Active trimming knife device of laminating machine

Abstract

The invention provides an active trimming knife device of a laminating machine and relates to the technical field of trimming knives of laminating machines. The active trimming knife device comprisesa base plate, the outer wall of the upper end of the base plate is fixedly connected with a supporting frame, a transmission shaft is inserted inside the supporting frame, the surface of the transmission shaft is rotatably connected with the supporting frame with the help of a bearing, the side wall of the supporting frame is fixedly connected with a driving motor, and an output shaft of the driving motor is fixedly connected with one end of the transmission shaft. A steel-made cutting knife is adsorbed and positioned through magnetism of a magnetic strip inside the knife rest, and a cushion block made of rubber and provided with grooves in the surface arranged between the cutting knife and the knife rest is utilized to buffer impact force between the same, so that the problem that a bladeis prone to serious wear when the blade cuts woven fabric with heavy gram weight is lowered; when the being worn, the cutting knife is broken to break a cutting knife breaking groove, in this way, effect of quick replacing of the blade is realized.

Description

technical field [0001] The invention relates to the technical field of edge trimming knife for a laminating machine, in particular to an active edge trimming knife device for a laminating machine. Background technique [0002] In the lamination production, it is necessary to trim the laminated cloth surface online to ensure the neatness of the edge of the woven cloth surface and the consistency of the width of the cloth surface. However, when the woven fabric is cut at high speed, especially when cutting some heavy and thick woven fabrics, when cutting with a passive straight blade, since only one point is always cutting, the blade is extremely easy to wear, and Straight blades bear a relatively large impact force when cutting thick woven fabrics. In order to ensure the rigidity of the straight blades, the thickness of the blades needs to be thickened, so that the cutting edges are more likely to become blunt, and the blades are frequently disassembled and replaced, thereby ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an active edge trimming knife device for a laminating machine, which reduces the impact between the blade and the woven cloth, reduces the loss of the blade, and solves the problem that the blade needs to be disassembled as a whole
