Abstract

The invention relates to the technical field of plastic film production, in particular to a cutting device for plastic film processing. The cutting device for plastic film processing comprises a turnover frame, a first bearing block, a second bearing block, a flattening roller, a transition roller, a rodless air cylinder assembly, a cutting assembly and a cutting control system. The first bearingblock is slidably connected to the turnover frame through a sliding block and sliding groove structure. Two ends of a spring are fixed to the first bearing block and the second bearing block correspondingly, and a first motor is fixed to the outer side of the second bearing block at one end. The cutting assembly comprises a lead screw transmission mechanism, a guide rod air cylinder mechanism anda cutting tool mechanism. The cutting control system is connected with and controls the turnover frame, the rodless air cylinder assembly, the lead screw transmission mechanism, the guide rod air cylinder mechanism and the first motor respectively. According to the cutting device for plastic film processing, during cutting, the film tension force is high, the cutting speed is high, the tool cutting edge using efficiency is high, and a flattening function is fulfilled.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a cutting device for plastic film processing. Background technique [0002] With the increasingly intensified competition in the plastics industry, film blowing machines are developing towards high speed and wide width. Film blowing machines also require larger and larger diameters of film rolls, and higher and higher quality film rolls. With the development of air pressure technology, the high-speed automatic film blowing machine can fold the film in half with a width of 2.1m, a speed of more than 80m / min, a film diameter of 1m, and an output of 400kg / min under the high quality of the film roll. h. The traditional roll changing mechanism is not only cumbersome to operate and labor-intensive during the roll changing process, but also easily produces waste. Therefore, the processing and production of existing plastic films mostly use PLC to control the roll chang...
