Adjustable telescopic automatic chain pressing device

Abstract

The invention provides an adjustable telescopic automatic chain pressing device. The adjustable telescopic automatic chain pressing device comprises a first chain pressing adjusting device, a second chain pressing adjusting device, a positioning sliding groove and a moving sliding groove. A first inner groove and a first through groove are formed in the positioning sliding groove, the first chain pressing adjusting device is arranged in the first inner groove so as to generate downward pressing force on a transmission chain penetrating through the first through groove, a guide sliding way is arranged on the side wall of the first through groove in the axial direction, and the guide sliding way is communicated with the first inner groove. A second inner groove and a second through groove are formed in the movable sliding groove, and a second chain pressing adjusting device is arranged in the second inner groove so as to generate upward jacking force on the transmission chain penetrating through the second through groove. The movable sliding groove is provided with a sliding block, the sliding block is detachably connected with the guide sliding way in a sliding mode, and the chain pressing position and the chain pressing length of the chain are adjusted when the movable sliding groove slides left and right along the guide sliding way and the positioning sliding groove. The transmission efficiency of the transmission chain can be improved, the running stability of the chain is improved, and the service life of the chain is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of the transmission chain tensioning equipment, in particular to an adjustable telescopic automatic chain pressing device. Background [0002] Chain drive equipment relies on the meshing of sprocket teeth and chain links to transmit movement and power, and is widely used in the silk production line of tobacco factories. Chain transmission according to the length of the chain, most occasions need tensioning device, common chain tensioning device for unilateral tension pressure sprocket, easy to produce loose edges and tight edges, the equipment in two-way movement of this phenomenon is more prominent, resulting in chain transmission instantaneous transmission ratio is not accurate, the transmission of dynamic load, resulting in poor rotation performance and other defects, easy to cause the chain instantaneous load is too large, so that chain fatigue damage caused by fault shutdown. In the actual production...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an adjustable telescopic automatic chain pressing device, which solves the problem that the transmission chain of the existing transmission equipment is prone to detachment and chain jamming due to the loose chain, can automatically adjust the tightness and compression state of the chain, and increase the transmission chain. Transmission efficiency, improve the stability and service life of the chain operation
