Knife roller belt transmission and tensioning device of leather shaving machine

Abstract

The invention discloses a knife roller belt transmission and tension device of a leather shaving machine, comprising a driving belt wheel, a driven belt wheel installed at one end of a knife roller shaft, and a transmission belt. A tension device is arranged on the transmission belt and comprises a tensioning belt wheel seat, a seat shaft, a tensioning belt wheel, a tensioning belt wheel shaft, a tensioning spring and a tensioning oil cylinder, the tensioning belt wheel seat can pass by the seat shaft and freely rotate around the seat shaft, the seat shaft is connected with a lathe body, the tensioning belt wheel can pass by the tensioning belt wheel shaft and freely rotate around the tensioning belt wheel shaft, the tensioning belt wheel shaft is connected with the tensioning belt wheel seat, one end of the tensioning spring is connected with the lathe body, the other end of the tensioning spring is connected with the tensioning belt wheel seat, an oil cylinder seat of the tensioning oil cylinder is connected with the lathe body, and a piston rod is connected with the tensioning belt wheel seat. The knife roller belt transmission and tension device of the leather shaving machine is simple in structure and good in practicability, can be used for conveniently adjust the pretightening force, the service life of the transmission belt is prolonged, the transmission capacity of the transmission belt and the shaving quality are improved, and good economic benefit and good social effect are achieved.

Description

technical field [0001] The invention relates to a leather shaving machine, in particular to a leather shaving machine knife roller belt drive tensioning device. Background technique [0002] The shaving machine is a precision processing equipment in the leather processing process. During the leather shaving process, the smoothness of the knife roller transmission has an important influence on the shaving quality of the leather. During the belt transmission process, due to the elongation of the transmission belt, the transmission of the knife roller shaft is unstable, which has an adverse effect on leather shaving. In order to eliminate this effect, a preload is often applied to the belt transmission, that is, to increase the belt Transmission tensioning device. The tensioning wheel is the most commonly used tensioning method for leather shaving machines. Due to the compact structure of the shaving machine, it is very inconvenient to adjust the pre-tightening force of the t...

AI Technical Summary

Problems solved by technology

Due to the compact structure of the shaving machine, it is very inconvenient to adjust the preload of the tensioning wheel and install and disassemble it.

Either the transmission belt is always in a tensioned state, which affects the service life of the transmission belt; or due to the inconvenience of adjusting the pre-tightening force, the transmission belt is slack due to long-term work, which affects the transmission stability of the knife roller of the shaving machine, thus affecting the shaving quality
