Plastic foam cutting device

Abstract

The invention relates to the field of manufacturing of plastic foams, and particularly discloses a plastic foam cutting device. The plastic foam cutting device comprises a rack, a moving mechanism andcutting mechanisms, wherein the rack is provided with a track; the moving mechanism comprises a sliding block, a hydraulic jack and a mounting seat; fixing holes are formed in the rack; positioning holes are formed in the sliding block; the mounting seat comprises a base and supports; the two cutting mechanisms are oppositely arranged along the base; each cutting mechanism comprises a heating piece, a stepping motor and winding rolls; a groove is formed in each support; a heating piece is fixed in each groove; a cutting rope is arranged on the mounting seat; the cutting rope penetrates through the side wall, which is opposite to an opening, of each groove; and two ends of the cutting rope are separately fixed on the two winding rolls; a fan is fixed on the mounting seat; and a worktable is arranged on the rack. According to the scheme, plastic foam melting is relieved in a cutting process by the cutting device.

Description

technical field [0001] The invention relates to the field of plastic foam manufacturing, in particular to the field of plastic foam cutting. Background technique [0002] Plastic foam is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, corrosion resistance, etc., and is easy to form and has good water resistance. Price It is also very cheap, so it is widely used in packaging, heat preservation, waterproof, heat insulation, shock absorption and other fields. It is one of the most widely used plastics in the world today. [0003] The preparation of plastic foam generally first introduces gas into liquid or molten plastic to generate micropores; then the micropores grow to a certain volume; then the microporous structure is fixed by physical or chemical methods to obtain plastic foam. However, companies that need to use plastic foam ...

Problems solved by technology

The raw material of plastic foam is generally polystyrene, and the cutting of plastic foam boards is generally to heat the cutter first. When cutting, the heat will melt the plastic foam boards in contact with the cutter, but due to the high temperatu
