BOPET (Biaxially Oriented Stretching Polyester Film) biaxially oriented stretching sheet transmission

Abstract

The invention discloses a BOPET (Biaxially Oriented Stretching Polyester Film) biaxially oriented stretching sheet transmission which comprises a bed, bases, a main transmission and a driven transmission. The main transmission and the driven transmission are arranged on the corresponding bases. The bases are arranged on the bed by bearings and bearing shafts. Both the main transmission and the driven transmission can drive a regulating screw rod by a speed reducer to implement the left-and-right movement, so that the problems that the integral transmission accuracy is low, the amplitude cannot be regulated and the like, which are caused by the case that the left-and-right direction cannot be regulated, are solved. A drive motor is arranged on a main transmission assembly of the main transmission and a hydraulic tensioning assembly is arranged on a driven transmission assembly of the driven transmission, so that the problems of poor operability of equipment, inaccuracy for positioning and high rejection rate are solved, and thus, the BOPET biaxially oriented stretching sheet transmission has the characteristics of high transmission accuracy, adjustable amplitude, good operability, accuracy for positioning, low rejection rate and the like.

Description

technical field [0001] The invention relates to a plastic film stretching device, in particular to a transmission device for a BOPET biaxially stretched sheet. technical background [0002] The BOPET biaxially stretched sheet transmission device includes the main transmission device and the passive transmission device, of which the BOPET biaxially stretched sheet main transmission device is mainly used for the transmission and fixture clamping of the fixture on the plastic film biaxially stretched sheet equipment. Adjustment of sheet width to meet the requirements of BOPET sheet stretching of different widths; BOPET biaxially stretched sheet passive transmission device is mainly used for plastic film biaxially stretched sheet equipment, the transmission of the fixture and the clamping of the BOPET biaxially stretched sheet The adjustment of the stretched sheet width, as well as the timely tension adjustment of the clamp chain used by the clamp, can meet the requirements of d...

AI Technical Summary

Problems solved by technology

[0007] The beneficial effect of the present invention is that: by installing the base with bearings and bearing shafts, neither the main transmission device nor the passive transmission device is fixed, which solves the problems of low overall transmission accuracy and inability to adjust the amplitude caused by the inability to adjust the left and right directions. problem, the transmission motor and hydraulic tensioning assembly set on the main transmission assembly and the passive transmission assembly solve the problems of poor operability of the equipment, inaccurate positioning, and high scrap rate, so that the present invention has high transmission precision, adjustable amplitude, and operability Good, precise positioning, low scrap rate, etc.
