Automatic belt-cutting machine capable of disconnecting braid adhesion

Abstract

The invention discloses an automatic belt-cutting machine capable of disconnecting braid adhesion, comprising a braid conveying mechanism and a braid cutting mechanism; the braid cutting mechanism comprises at least one cutting board and a hot knife assembly correspondingly arranged above the cutting board; the top surface, in contact with a braid, of the cutting board is axially upward, and the rear end, close to the braid conveying mechanism, of the cutting board is provided with a guide groove; the side of the rear end of the cutting board is mounted with a gas nozzle, and the nozzle of thegas nozzle just faces the guide groove; the front end of the top surface of the cutting board is provided with a vertical guiding slot, the vertical guiding slot is internally provided with an abhesion top plate, and a jacking mechanism capable of ejecting the abhesion top plate to be higher than the top surface of the cutting board is arranged below the abhesion top plate; the abhesion top plateis capable of ejecting the adhesion end of the braid which has been cut into sections under the effect of the jacking mechanism, and a return spring is arranged at the side surface of the abhesion top plate.By adopting the automatic belt-cutting machine provided by the invention, the defect that the subsequent cutting work is affected by the fact that the soft braid is adhered to the cutting board after hot cutting is solved, and the application range of the automatic belt-cutting machine is widened.

Description

technical field [0001] The invention relates to a webbing cutting device, in particular to an automatic webbing cutting machine capable of releasing the adhesion of webbing. Background technique [0002] As we all know, webbing is woven from many yarns. If it is cut with a cold knife, the fracture will fall apart. Therefore, it must be cut with a hot knife, and the thermal melting of the hot knife can make the webbing at the cutting cut stick together without falling apart. [0003] Although the hot knife melting and cutting has solved the problem of the incision spreading out. However, hot knife cutting relies on high temperature to dissolve chemical fibers. Chemical fibers will produce some stickiness when melting, and stick the fibers at the fracture to the chopping board. The adhesion when the chemical fiber melts does not affect the normal work of the webbing with a certain hardness, because the thrust of the webbing with a certain hardness is greater than the adhesiv...
