Summary of the invention

The objective of the invention is to seek a kind of simple in structure, be active in one's movements, low-cost and can increase substantially the dancer institutional reform and the device of the up-and-down movement of adjusting dancer tension force precision.

Technical scheme of the present invention is:

A kind of dancer mechanism on the cutting machine, one end piston rod of two bar double-acting cylinders is connected to the top of an end of dancer with stay cord, the other end piston rod of two bar double-acting cylinders is connected to the below of the dancer other end with another root stay cord, connect remaining top and bottom, dancer two ends with the 3rd stay cord by several pulleys again, the displacement pickup afterbody is installed on the framework, external part is installed in an end rod end of two bar double-acting cylinders, the two ends of dancer by bearing installation to line slideway, two bar double-acting cylinder one actions, dancer just can be done up-and-down movement up and down on line slideway.

There is remarkable advantages in this dancer mechanism for the dancer mechanism on other cutting machine, generally speaking can reduce simple in structure, cost reduces, be active in one's movements, resistance reduces, be easy to control and guaranteed that the dancer two ends can synchronization action.Dancer on the cutting machine all had two cylinders in the past, control the two ends of dancer respectively, because the influence of control cock in some characteristics of gas and the gas circuit, can not guarantee that the dancer two ends move simultaneously, and then reduced the dancer control precision of tension, even can make film produce fold, shake, speed is cut in influence, reduces end product quality.The present invention only adopts two bar double-acting cylinders to drive dancer and has just solved the problems referred to above, and has saved cost, is beneficial to control.The dancer two ends circular roller bearing units of band boss among the present invention, the relative form of roller two ends captive joint in the past, this bearing has certain automatic aligning function, the problem of shake when having reduced the roller motion that brings owing to installation error.
