Waste edge cutting device for machining special film for automobile blanket

Abstract

The invention discloses a waste edge cutting device for machining a special film for an automobile blanket, and belongs to the technical field of special films for the automobile blankets. The waste edge cutting device comprises a base and cutting mechanisms, wherein a mounting groove is arranged in the middle of the base; supporting plates are symmetrically and fixedly connected to the left sideand the right side of the upper end of the base; a roller shaft is movably connected to the lower ends of the supporting plates; a rotating roller is fixedly connected to the middle of the roller shaft; one side of the roller shaft is sleeved with a transmission belt; the end, away from the roller shaft, of the transmission belt is sleeved with a motor shaft; and a driving motor is fixedly connected to one side of the motor shaft and is fixed to the corresponding supporting plate. According to the waste edge cutting device, sliding blocks are slidably connected to the middles of mounting frames in the cutting mechanisms arranged at the left end and the right end of a mounting base, spring sets are symmetrically and fixedly connected to the upper ends and the lower ends of the sliding blocks, the mounting frames are fixedly connected to the ends, away from the sliding blocks, of the spring sets, cutting pieces fixedly connected to the middles of rotating shafts are movably connected tothe ends, away from the mounting frames, of the sliding blocks, waste edges are conveniently cut off, and the cutting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of special films for automobile blankets, in particular to a waste edge cutting device for processing special films for automobile blankets. Background technique [0002] Films for automobiles usually use polyvinyl alcohol aqueous solution and have good film-forming properties; polyvinyl alcohol films have many characteristics different from other plastic films; , but its unique performance is still recognized by the market; with the further development of manufacturing and processing technology and the expansion of the scope of use, the demand is increasing year by year; polyethylene drunk film mainly has the following four types, that is, used for fiber product packaging Soft film, release film for moldings such as polyester, water-soluble film and film for food packaging; about 90% of the current production is for fiber product packaging; [0003] However, the cutting method used in the film processing p...

Problems solved by technology

[0003] However, the cutting method used in the processing of the film in the prior art mostly uses a unified cutting device for cutting, and it is not flexible. During processing, the cutting cannot be adjusted according to the size of the film, and the processing efficiency is low.
