1. First, check the reason for the falling off of the hinge. If the hinge itself is broken, just replace it with a new hinge; if the screw on the hinge is loose, just replace the screw. It is recommended to replace it. Choose a larger screw and screw it on, so that the hinge is repaired.


2. Hinged installation: Align the hole of the hinge with the hole of the cabinet door, and then fix it with screws. After fixing, try to close the door to make sure that it is correct.

According to the type of lubricating oil, it is also divided into grease lubrication and oil lubrication. Grease lubrication generally needs to choose different greases according to the premise and situation. Under normal circumstances, every 100 kilometers of work, grease lubrication needs to be supplemented. Oil lubrication requirements Linear guides are coated with anti-rust oil, and only linear guides coated with anti-rust oil can be lubricated.
It is worth noting that in the use of very low temperature, the lubricating oil will often be washed away, and the slide rail will reduce the lubricity of the linear guide. Therefore, for places with low temperature, pay attention to the degree of lubrication and lubricate it at any time. Improve the lubrication frequency and the amount of lubrication, so that the linear guide is well maintained and maintained. The above are the tips on the lubrication of linear guides. I remind everyone that when choosing a lubricant, it must be decided according to the purpose of the work, so as to ensure better use.

The workload of sugarcane harvesting accounts for about 55% of the total sugarcane planting work, and the leaf stripping time accounts for about 60% of the sugarcane harvesting time. The key link of planting mechanization operation level. Sugarcane planting in the United States, Brazil, Cuba, Australia and other countries is mostly large-scale contiguous planting, and the whole process of mechanization of planting, management, and harvesting has been basically realized. Most sugarcane harvesting uses efficient high-power combined harvesting.
Before the sugarcane is harvested, the stems and leaves of the sugarcane are burned with fire, and then the sugarcane is cut into cane segments by a large combine harvester, and the remaining wrapped leaves are removed by the axial flow exhaust fan on the harvester. The harvester does not have a leaf stripping mechanism.
Most of the sugarcane areas in China, Japan, India, Thailand, the Philippines and other Asian countries are hilly areas, mostly on hillsides and small plots. The terrain is complex, and the sugarcane planting is irregular and not in pieces. It is not suitable for large-scale combine harvesters. The main promotion is a small segmented harvesting system composed of sugarcane harvester, sugarcane leaf stripper, and transport machinery. Sugarcane leaf stripping is mainly completed by using an independent sugarcane leaf stripper or installing a leaf stripping mechanism on a full-bar sugarcane harvester. The peeling mechanism is the core device of the sugarcane leaf peeling machine.
Since the 1980s, relevant scientific research institutes and colleges and universities in China have increased the research and development of sugarcane harvesting machinery, including the sugarcane leaf peeling machine. They have introduced advanced models from Japan, Australia, and other countries for digestion and absorption, and successfully developed a batch of leaf strippers whose main technical indicators have reached the level of similar foreign models. These leaf strippers are mainly equipped with centrifugal drum-type leaf stripping mechanisms. However, the leaf stripping effect of the centrifugal drum-type sugarcane leaf stripper is still unsatisfactory, and the main technical indicators such as impurity content, skin damage rate, breakage rate, leaf stripping element life, and machine adaptability still cannot meet market requirements. Specifically, the leaf stripping element life is short and the impurity content is high, which hinders the popularization of sugarcane leaf strippers.
Therefore, it is of great importance to strengthen the research and development of sugarcane leaf stripping mechanisms for improving the mechanized operation level of China's sugarcane planting industry.
Currently, the nation's domestic market for leaf stripping machines mainly utilizes centrifugal drum-type leaf stripping mechanisms composed of a feeding wheel, a stripping roller, and stripping elements. However, several issues exist with this design.
Firstly, the leaf stripping effect is not ideal. The centrifugal drum-type sugarcane leaf stripping mechanism relies on repeated blows, friction, and dragging from the leaf stripping elements to remove the sugarcane leaves. Due to the arrangement of two leaf stripping rollers along the sugarcane radial direction, there is a blind area where the leaves are not completely peeled off, leading to a high impurity rate and skin damage rate.
Secondly, the leaf stripping elements have a short service life. The repeated impact and friction during work cause wear and tear, with stripping elements such as rubber fingers and nylon wire being particularly susceptible to damage. Additionally, steel wire and steel brush leaf stripping elements have a high skin damage rate.
Thirdly, maintaining the leaf stripping elements is inconvenient. The small and sealed space in which the leaf stripping elements are installed makes maintenance and replacement troublesome.
Lastly, the centrifugal drum-type leaf stripping mechanism has poor adaptive ability. With sugarcane mainly grown in typhoon-prone areas with varying curvatures, the fixed structure of the transmission and transmission devices makes it difficult to automatically adapt to sugarcane with different diameters and curvatures, resulting in a high breakage rate.
To address these problems, a new design for the leaf stripping mechanism has been proposed. This design includes a spring hinge adaptive leaf stripping mechanism and a caudal lobe cutting and peeling mechanism.
The caudal lobe cutting and peeling mechanism is responsible for cutting off the tail of the sugarcane and peeling off the young leaves at the tail to prepare for the peeling of the sugarcane stems and leaves. It consists of a tail cutting saw blade, a tail cutting knife barrel, a tail leaf peeling knife installation rod, and a tail leaf peeling knife.
The main leaf stripping mechanism, on the other hand, consists of a feeding wheel, leaf stripping knife, spring hinge mechanism, and other parts. The leaf stripping knives are connected to the fixed frame through hinges and are pressed by springs. The rotation of the leaf stripping knife rod around the hinge allows for automatic adaptation to changes in sugarcane diameter. The upper leaf stripping knife is opened under gravity, while the lower leaf stripping knife is lifted upwards by the spring force. This design ensures that four stripping knives wrap the sugarcane stem concentrically, allowing for efficient and thorough peeling of the sugarcane stems and leaves.
The leaf stripping machine, designed as a double-station trolley type, also integrates two tail leaf cutting and stripping mechanisms. These mechanisms, along with the main leaf stripping mechanism, have shown excellent leaf stripping effects, strong self-adaptive ability, and a long leaf stripping knife service life.
In conclusion, the new design of the leaf stripping mechanism offers improved performance over the centrifugal drum-type leaf stripping mechanism. The spring hinge adaptive leaf stripping mechanism and caudal lobe cutting and peeling mechanism address the shortcomings of the previous design, resulting in enhanced peeling efficiency, lower impurity and skin damage rates, and easier maintenance and repair. By implementing these improvements, China's sugarcane planting industry can achieve higher levels of mechan

In recent years, the automobile industry in my country has experienced rapid development, particularly with the addition of self-owned brands and joint venture brands. This has led to a reduction in automobile prices and a flood of tens of thousands of cars entering the consumer market annually. As the times progress and people's incomes improve, owning a car has become a common means of transportation in thousands of households, contributing to increased production efficiency and improved quality of life.
However, the frequent occurrence of car recalls due to design problems in the automotive industry serves as a reminder that when developing new products, attention should not only be given to development cycles and costs, but also to product quality and user needs. To ensure better quality and satisfaction for consumers, the "Three Guarantees Act" for automotive products sets stricter requirements, including a minimum validity period of 2 years or 40,000 km, and a minimum validity period of 3 years or 60,000 km. Therefore, it is crucial to focus on the early stages of product development, optimize the design structure, and avoid the need to "make up for" any shortcomings later on.
One specific area of concern in the automotive industry is the occurrence of cracking in the inner panel at the hinge of the liftgate hinge reinforcement plate. This problem was encountered during road tests of actual vehicles, leading to the need to investigate how to reduce the sheet metal stress value in the hinge area. The aim is to optimize the structure of the hinge reinforcement plate and achieve the optimal state to reduce stress values and enhance the performance of the liftgate system. Using computer-aided engineering (CAE) tools for structural optimization can improve the quality of design, shorten the design cycle, and save testing and production costs.
The analysis of the cracking problem in the inner panel at the liftgate hinge revealed that the boundary at the hinge installation surface and the upper boundary of the hinge reinforcement plate were staggered, causing the inner panel to be under a single-layer stress state, which did not provide adequate protection to the inner plate. This resulted in a cut in the upper boundary of the hinge installation surface, leading to increased cracking. Furthermore, stress concentration at the lower end of the hinge mounting surface exceeded the yield strength of the plate, posing a risk of cracking.
To address these issues, various structural optimization schemes were proposed and analyzed through CAE calculations. Four different schemes were designed, and the stress values of the inner plates were calculated and compared. The results showed that all optimization measures were effective in reducing stress values, with scheme 4 achieving the greatest reduction. However, implementing scheme 4 would require significant changes to the manufacturing process, leading to high mold repair costs and a long renovation period. Scheme 2, which achieved a 35% reduction in stress values compared to the original scheme, was deemed the most feasible and cost-effective solution.
To validate the effectiveness of the chosen scheme, manual samples of the modified parts were created, and vehicle manufacturing and reliability road tests were conducted. The results showed that scheme 3 and scheme 4 were successful, while scheme 1 failed. Based on these findings, the optimal improved structural design scheme (Scheme 4) of the hinge reinforcement plate was determined. However, to address issues of process convenience and perceived quality, further improvements were made to the structure of Scheme 4, resulting in a final design that eliminated boundary staggering, improved process operation, and ensured consistent application of sealant.
In conclusion, the analysis, optimization, and validation of the hinge reinforcement plate structure demonstrated that the reduction of stress values in the inner plate at the hinge is closely related to the design of the hinge reinforcement plate. While increasing sheet metal or using special processes can achieve some reduction in stress values, these approaches often complicate the process and increase costs. Therefore, it is crucial to carefully design and optimize the structure of the hinge reinforcement plate from the early stages of product development to achieve the best results in terms of stress reduction. Continuous improvement in product design and manufacturing processes is essential to meet the increasing demands for quality and reliability in the automotive industry.
