Description

Technical Field

[0001] The utility model relates to a fixed-length cutting device for rubber plate processing, belonging to the technical field of rubber plate processing. Background Art

[0002] Rubber sheet is a sheet product with a certain thickness and a large area made of rubber as the main material through vulcanization. It is referred to as rubber sheet. Rubber sheet has high hardness and general physical and mechanical properties. It can work in air with low pressure and temperature of 20°~+140℃. Rubber sheet is made of mixed rubber through calendering and laminating or extrusion molding, vulcanized with a flat vulcanizer or continuously vulcanized with a drum vulcanizer.

[0003] The existing patent number is CN212608481U, which is a cutting device for processing rubber sheets. This device abuts the rubber sheet with the second limiting plate and the first limiting plate, so that the rubber sheet does not move horizontally during the rolling process, which solves the problem that the common cutting device for processing rubber sheets cannot ensure straight cutting because the rubber sheet is not fixed during cutting; thanks to the cooperation of the electric telescopic rod and the T-shaped slide groove, the horizontal movement of the second limiting plate is realized, thereby playing a role in adjusting the distance between the first limiting plate and the second limiting plate according to the width of the rubber sheet, thereby adapting to rubber sheets of different widths and increasing applicability; the function of turning the knob to drive the movable plate to move horizontally is realized through the cooperation of the screw rod, the slide rod and the movable plate. Thus, it plays the role of adjusting the cutting head horizontally, and solves the problem that the cutting head position is fixed when cutting with common cutting equipment for rubber sheet processing, and it is difficult to adjust the cutting position according to needs. However, although this device can limit the front and rear positions during the cutting process of the rubber sheet, it is difficult to automatically feed the rubber sheet, and it has a limiting effect when clamped by the limiting plate, and it cannot continuously cut the rubber sheet, thereby affecting the cutting efficiency of the rubber sheet; and it is difficult to cut a fixed length during the cutting process. Although the position of the cutting tool can be adjusted, it is also necessary to measure the cutting position, and it is impossible to continuously and automatically cut the rubber sheet at a fixed length. .
