AI Technical Summary

Technical Problem

The existing film production equipment lacks guidance on the cutting edge during the cutting process, resulting in the cut edge being squeezed at the cutting knife, interfering with the travel of the remaining film material.

Method used

A PVC film edge cutting device is designed, using an arc cutter and a lifting mechanism. The arc cutter is driven to move on the workbench through the lifting mechanism, and the cut edge moves along one side of the cutter to avoid disturbing the normal movement of the film material. At the same time, the cutting knife adjustment mechanism can be independently adjusted.

Benefits of technology

It effectively avoids the cutting edge interfering with the movement of the film material, improves the cutting effect of the film, and flexibly adjusts the cutting position of the edge by independently adjusting the cutting knife position.

[0028] A lifting slot 204 is provided downwardly at the center of the top of the side plate 201, a top plate 205 is provided on the top of the lifting slot 204, a lifting cylinder 206 is fixedly installed on the top of the top plate 205, the output shaft of the lifting cylinder 206 passes through the top plate 205 and is fixedly connected to the lifting seat 207, and the lifting cylinder 206 can drive the lifting seat 207 to move up and down;

[0029] Specifically, in this solution, the front and rear side walls of the lifting slot 204 are vertically provided with lifting rails 208, and the front and rear side walls of the lifting seat 207 are provided with slide grooves 209 corresponding to the lifting rails 208. The lifting seat 207 is stuck in the lifting rails 208 through the slide grooves 209 to limit its displacement in the horizontal direction.

[0030] In this solution, in order to improve the stability of the two lifting mechanisms 2, the side plates 201 of the two lifting mechanisms 2 are fixedly connected by at least four connecting rods 202;

[0031] The cutter adjustment mechanism 3 is used to adjust the position of the cutter 4 in the left-right direction, thereby adjusting the width of the cutting edge of the cutter;

[0032] like Figure 6-8 The cutter adjustment mechanism 3 includes a mounting tube 301, a trapezoidal lead screw 303 and a sleeve 306;
