Problems solved by technology

In the foaming production line of the refrigerator, the mold trolley needs to be started and stopped frequently during the movement process, which may easily cause the driving chain to loosen and cause inaccurate positioning. The above-mentioned mechanical structure is used to adjust the tension of the chain, and it is necessary to stop the equipment frequently to tension the chain. , the adjustment process is complicated and time-consuming, resulting in low production efficiency

Abstract

The invention discloses an automatic take-up hydraulic device for a chain of a heavy load production line. The automatic take-up hydraulic device comprises two hydraulic motors simultaneously connected with the chain of the production line, wherein the two hydraulic motors are respectively connected different hydraulic pumps with different driving pressures, and the two hydraulic motors are respectively driven to rotate in different direction through the two hydraulic pumps, but one hydraulic motor with the lower driving pressure is co-rotated along with the driving of the other hydraulic motor due to small torque. The device can be automatically taken-up and simply controlled, and can greatly improve production efficiency, and simultaneously improve working accuracy and equipment stability.

Description

technical field [0001] The invention relates to an automatic production line, in particular to an automatic tensioning hydraulic device for production line chains in heavy-duty working conditions. Background technique [0002] The automatic production line, especially the heavy-duty production line, has a large load. After the chain is used for a long time, it will become loose due to the increased gap, which will affect the production accuracy and the quality of the processed product. In order to avoid adverse effects caused by chain loosening, it is necessary to set up a special chain tensioning device. After the chain is loose, the chain is tensioned in time to ensure production accuracy and product quality. For example, in the production line of multi-station refrigerator box foaming, there is a tensioning device with mechanical structure. The production line uses a hydraulic motor to drive a large chain to drive the foaming mold trolley to run on the track. When the mol...
