Device for slitting waterproof material and method for slitting waterproof material

Abstract

The invention relates to equipment and a method in the technical field of waterproof materials, and provides a device for slitting a waterproof material and a method for slitting the waterproof material. The device for slitting the waterproof material comprises a machine frame, wherein a conveyor is arranged on the machine frame; a slitting knife driven by a power device is further arranged on the machine frame; the slitting knife operates downwards under the action of the power device to slit the waterproof material; slitting backing plates are arranged under and behind the slitting knife; and a first refrigeration part is arranged in each slitting backing plate. The method for slitting a waterproof material comprises the step of slitting the waterproof material at a low temperature of 0-5 DEG C. The device for slitting the waterproof material and the method for slitting the waterproof material have the advantages that the waterproof material is easy to slit, and the coating in the waterproof material is not likely to be adhered to the slitting knife.

Description

technical field [0001] The invention relates to equipment and methods in the technical field of waterproof materials, in particular to a waterproof material cutting device and a waterproof material cutting method. Background technique [0002] Waterproof materials are products made of waterproof coatings paved into thin sheets. The main components are denatured asphalt, resin glue and other materials. These waterproof coatings generally have the properties of softening at high temperatures and hardening at low temperatures. [0003] Cutting large pieces of waterproof materials into appropriate small pieces of waterproof materials is the cutting of waterproof materials; in the prior art, heating and cutting methods are generally used. Waterproof materials are relatively soft and easy to cut at high temperatures, but waterproof The viscosity of the material is also large at high temperature, so that the waterproof material is easily bonded to the slitting knife, which is incon...

AI Technical Summary

Problems solved by technology

[0003] Cutting large pieces of waterproof materials into appropriate small pieces of waterproof materials is the cutting of waterproof materials; in the prior art, heating and cutting methods are generally used. Waterproof materials are relatively soft and easy to cut at high temperatures, but waterproof The material is also viscous at high temperature, so that the waterproof material is easily bonded to the slitting knife, which is inconvenient for the next slitting agent

[0004] The waterproof material cutting device includes a frame with a transmission device on the frame and a cutting knife driven by a power device on the frame. The cutting knife moves downward under the action of the power device to cut the waterproof material , there is a slitting backing plate under and behind the slitting knife; in the prior art, there is a heating component on the slitting backing plate, which is to slit the waterproof material to be cut when it is softened after the waterproof material is softened. Such a cutting device has the disadvantage that the paint in the waterproof material is easily bonded to the cutting knife
