Laminating machine active trimming knife device

Abstract

The invention relates to an active trimming cutter device for a laminating machine. A sliding block is mounted in a sliding manner on a bracket; the sliding block implements reciprocating linear motion by a first driving device; a rotating device is fixedly mounted on the sliding block; an active round cutter is fixedly mounted on the rotating device; the rotating device drives the active round cutter to rotate; a second driving device and a third driving device are mounted on the sliding block; the third driving device drives the second driving device to implement reciprocating linear motion; the second driving device and the first driving device are arranged in parallel; a passive round cutter is fixedly mounted on the second driving device; a cutting edge of the passive round cutter is matched with a cutting edge of the active round cutter. According to the active trimming cutter device for the laminating machine, which is disclosed by the invention, the service life of a cutting knife is prolonged; different requirements of thick and thin woven cloth covers for a cutter gap are met; compression springs are uniformly distributed between the active round cutter and a tool rest and can repair a deviation in the mounting process and a size error caused by wearing in the using process; online regulation of the position can be realized for the entire active trimming cutter device.

Description

technical field [0001] The invention relates to the technical field of an active trimming device for a cloth surface after lamination, in particular to an active 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, resulting in frequent replacement of the blades, the...

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, resulting in frequent replacement of the blades, which affects the quality of the product.
