Full-automatic foam thin cutting device

Abstract

The invention discloses a full-automatic foam thin cutting device. The full-automatic foam thin cutting device comprises a rack, a foam feeding mechanism and a cutting mechanism, wherein the foam feeding mechanism and the cutting mechanism are arranged on the rack; the foam feeding mechanism comprises a feeding base and a driving device for driving the feeding base to move; the cutting mechanism comprises a band knife support, an annular band knife device installed on the band knife support, a band knife operation precision control device and an inching feeding control device; and the annularband knife device uses a band knife to cut a foam part, the band knife operation precision control device controls the stability and precision of the band knife during cutting, and the inching feedingcontrol device controls the cutting position of a band knife cutting edge. According to the full-automatic foam thin cutting device, the continuously running annular band knife is used for cutting the foam part, the running precision of the band knife is controlled, and meanwhile, the band knife and the feeding base are controlled and matched through the inching feeding control device, so that cutting marks are prevented from being left on the cutting surface by a band knife joint, uniform slicing is realized, the cutting surface is smooth and flat, few chips are generated in the cutting process, and environmental protection and health are achieved.

Description

technical field [0001] The invention relates to a material cutting device, in particular to a fully automatic foam thinning device. Background technique [0002] Rigid foam usually needs to be cut into foam sheets with a specific layer thickness, such as polymethacrylimide foam (hereinafter referred to as PMI foam), because of its large molecular weight and good hardness, it is currently a new type of high-density foam with the best overall performance. Molecular structure foam materials have the characteristics of light weight, high strength, high / low temperature resistance, etc., but they often need to be cut when they are used in aviation core materials and other fields. [0003] Usually, the thick foam block is reciprocally sawed or sliced ​​by a saw blade to cut into pieces, but the foam block is hard, and sawing will produce a large amount of foam slag, and will cause the cutting surface to be uneven, and because the thickness of the saw blade is limited, During the s...

Problems solved by technology

[0003] Usually, the thick foam block is reciprocally sawed or sliced ​​by a saw blade to cut into pieces, but the foam block is hard, and sawing will produce a large amount of foam slag, and will cause the cutting surface to be uneven, and because the thickness of the saw blade is limited, During the sawing process, the friction between it and the foam slab is large, which makes it impossible to achieve thin cutting, and the loss of the tool is relatively large, and the tool needs to be replaced frequently; while the piece cutting needs to first cut the foam plate thin and then use the roller to clamp and position , but there will be raw material damage or waste

In addition, the existing cutting equipment cannot realize the precise adjustment and control of the cutting size of foam materials, the cutting efficiency is low, and it is difficult to meet the utilization requirements of thin-cut foam sheets
