A PVC ultra-permeable film calendering and winding device

Abstract

The invention discloses a novel PVC super-transparent thin film coiling device. The Novel PVC super-transparent thin film coiling device comprises a rack, rollers connected to the two ends of the rack correspondingly, lifting tables symmetrically arranged on the two sides of the rollers, and cross beams located above the rollers. Pressurization rollers are arranged above the rollers. Two bearing seats are symmetrically arranged at the two ends of the rollers. A first synchronizing shaft and a second synchronizing shaft are connected to the two bearing seats correspondingly in a sleeved mode. The ends, far away from the rollers, of the two bearing seats are symmetrically provided with a first swing device and a second swing device correspondingly. A first holding frame and a second holding frame are symmetrically connected to the first synchronizing shaft and the second synchronizing shaft through the first swing device and the second swing device correspondingly. A sliding rail is arranged between a first synchronous gear and a bear and slidably connected with an L-shaped hook plate. Lifting devices are symmetrically arranged on the side, far away from the L-shaped hook plate, of the rack and are connected with pipe hook plates. One sides of the lifting devices are provided with lever mechanisms. An inclined plate with a limiting switch is arranged between the L-shaped hook plate and the pipe hook plates. A first cylinder is arranged above the inclined plate. A controller is arranged above the first cylinder.

Description

technical field [0001] The invention relates to a plastic processing equipment, in particular to a PVC ultra-permeable film coiling device. Background technique [0002] The existing PVC ultra-permeable film is processed from the plastic film that has been cooled and shaped by the rear cooling wheel from the calender, and then heated and rolled by the rubber wheel. The existing PVC coiler consists of two air The expansion shaft is composed of circulation, and the pressure roller is fixed on the holding table. When the finished product arrives at the yard, the rubber roller breaks away from the ultra-thin film product, and then the air expansion shaft switches to the cutting position, and then cuts off the film and circulates. At this time, the pressure roller is away from the ultra-transparent film for too long. During the time when the pressure roller is separated from the ultra-transparent film, air will enter the film during the winding process. During the period when th...

Problems solved by technology

At this time, the pressure roller is away from the ultra-transparent film for too long. During the time when the pressure roller is separated from the ultra-transparent film, air will enter the film during the winding process. During the period when the pressure roller is separated from the product, there will be air bubbles, and the transparency of the film will increase. Poor, the quality cannot be guaranteed after the rubber roller is separated, and it will cause waste; therefore, a super-permeable pressurization machine for PVC calendering and coiling machine is developed, which is simple in structure, easy to use, and the shorter the time for the pressure roller to leave the finished product, the better. The device has become an urgent problem to be solved in related industries
