Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrical machinery, specifically related to a constant tension take-up and pay-off electrical machinery equipment of frequency conversion drive. BACKGROUND

[0002] In many fields of industrial production, such as papermaking, printing, textile, cable manufacturing and other industries, there is a high requirement for tension control during take-up and pay-off. With the rapid development of industrial automation and power electronics technology, constant tension take-up and pay-off electrical machinery equipment driven by frequency conversion emerges as the times require. With the help of advanced frequency conversion speed regulation technology, the equipment can accurately adjust the motor speed in real time, cooperate with the tension detection and feedback system, automatically compensate the tension change caused by factors such as material diameter change and mechanical resistance fluctuation during take-up and pay-off, and ensure that the material maintains stable tension during the entire take-up and pay-off process, greatly improving product quality and production stability and continuity, and becoming an indispensable key equipment in modern industrial production.

[0003] At present, the chain transmission part is prone to wear at the connection between chain links under long-term operation and lack of good lubrication, resulting in chain elongation. After the chain elongation, tooth skipping phenomenon occurs, affecting the transmission accuracy and interfering with the constant tension control. At the same time, if the lubricating grease is not added in time or the amount is insufficient, the friction at the chain will increase, generating too much heat and accelerating the wear of the chain, affecting the smoothness of equipment operation and causing small range tension fluctuation.

[0031] The design of the lubricating mechanism 200 helps to solve the problem of untimely or insufficient addition of lubricating grease, the storage box 201 is used for storing lubricating grease and provides sufficient grease source for lubrication of chain and other components, the adjusting support 202 can adjust the position of the oil injection part 204 so as to better align the parts needing lubrication of the chain, the extraction hose 203 extracts the lubricating grease in the storage box 201 and delivers it to the oil injection part 204, and finally the lubricating grease is accurately added to the chain and other components through the oil outlet pipe head 204d, thereby ensuring the timeliness and accuracy of the addition of lubricating grease, avoiding the problems of increased friction, excessive heat and chain wear caused by insufficient lubrication and maintaining the stability of equipment operation and reducing tension fluctuation.

[0032] The structural design of the oil injection part 204 further optimizes the lubrication process, the pipe body 204a serves as a delivery channel of lubricating grease and is installed at the rotating shaft of the outer side of the adjusting support 202 and can be flexibly adjusted in direction, the illuminating lamp 204b at the top provides illumination for oil injection operation, which facilitates the operator to accurately align the oil outlet pipe head 204d with the parts of the chain needing lubrication, especially in a dark working environment, which helps to improve the accuracy of oil injection, the extension hollow rod 204c can be adjusted in length according to actual needs, making the oil injection more flexible and being able to adapt to the lubrication needs of the chain in different positions and working conditions, ensuring that the lubricating grease can be evenly added to each part of the chain and effectively preventing the chain wear from being aggravated due to insufficient local lubrication, thereby ensuring the stability of chain transmission and reducing the interference with constant tension control.

The flow guide strip 102a-2 can guide the excess grease added to the chain to flow into the collection groove 102a-3 to avoid the random flow of the grease. The through hole 102a-4 and the oil injection hole 102a-5 facilitate the oil injection operation of the chain transmission component and the discharge of the moisture or other impurities that may accumulate in the protective shell 102a-1, which helps to maintain a good lubrication environment, further reduces the wear of the chain, ensures the transmission precision of the chain, and thus ensures the stability of the constant tension control.
