Longitudinal cutting device for rubber sheet cooler

Abstract

The invention discloses a longitudinal cutting device for a rubber sheet cooler. The device comprises a longitudinal cutting frame and at least one group of longitudinal cutter devices fixed on the longitudinal cutting frame, wherein the longitudinal cutter device comprises a cylinder fixed on a support; the piston rod end of the cylinder is fixedly connected with a slide bar; and a longitudinal cutter is fixed on the slide bar end; and the support is fixedly connected with the longitudinal cutting frame through a transition block. The longitudinal cutter device is fixed on the transition block which can be adjusted along the longitudinal cutting frame, according to the requirement of manufacturers, the number of the longitudinal cutters can be regulated, the distance among the cutters can be adjusted, and upper and lower gaps among the cutters can be tuned; the longitudinal cutters are driven by a double-acting air cylinder to realize control automation; the slide bar is set to be a square structure, and is limited in a square groove of the transition block to avoid deflection of the cutter device, protect the air cylinder and improve the impact resistance; the cutters are fixed by a left splint and a right splint to increase the distance between a cutter bed and a cutter rest, the cutters rotate flexibly, so the glue plugging phenomenon is prevented, and the blade can be adjusted and changed conveniently; the cutters is in a double-sided edge structure to ensure that two sides of the cutter are stressed uniformly, the deflection force is reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tire rubber machinery, and mainly relates to a device for vertically cutting rubber materials on the film cooling line of a banburying workshop. Background technique [0002] The cooling device is a traditional auxiliary equipment for rubber processing. It is mainly used to hang and cool the thermal film. It generally includes a receiving device, a slitting device, a joint compacting device, a soaking device, an air-cooled conveying device, and a swing lamination device. . [0003] The original film coolant slitting device is to directly fix multiple groups of slitting knife devices on the slitting frame through the double-rod cylinder, and screw the knife holder with internal thread into the piston rod end of the double-rod cylinder , and then locked with a hexagonal thin nut. The knife seat is fixed with the knife and the knife holder through the small shaft, and there are two bearings in the knife ho...

Problems solved by technology

[0004] However, the distance between the slitting knives in the prior art cannot be adjusted. For the rubber film, its thickness and toughness are relatively large, especially at the joint of the rubber material, which has a great impact on the blade. Deflection, the disc knife is twisted and damaged by force, which will also reduce the life of the knife, and the disc knife is too small, which will cause material blocking or incomplete cutting.
