Foam material three-dimensional embossing process

Abstract

A foam material three-dimensional embossing process comprises the following steps that S1, a plate and a PE film are synchronously fed into an embossing device, wherein the PE film is located at the upper end of the plate; s2, fusing and embossing the PE film and the plate are realized in one step through a hot pressing process of the embossing device; and S3, after the fused and embossed plate is cooled, slitting is conducted, and the three-dimensional embossed plate is obtained. According to the invention, the integrated embossing process can be realized in one step, and the production efficiency is greatly improved. The invention further provides the embossing device, and the purpose of completing fusion of the PE film and the plate and the embossing process in one device is achieved; and the device has the advantages of being low in equipment cost, high in production efficiency and good in embossing effect.

Description

technical field [0001] The invention belongs to the technical field of foam boards, and in particular relates to a three-dimensional embossing process for foam materials. Background technique [0002] At present, the PE foam board on the market is composed of board and PE film. The PE film is blown to the required width and thickness after the PE raw material is processed by the blown film method, and then cooled and rolled, and then the rolled PE The film is put into the embossing machine. At this time, the board is also put into the embossing machine. The PE film and the board are fused by heating the PE film again, and finally the fused PE film and the board are embossed to form a PE hair. Foam board, the embossed PE foam board is put into the slitting machine for cutting to complete the finished product. The above-mentioned production process needs to be transported to different equipment for processing in actual production, which not only has high equipment cost, but a...

Problems solved by technology

[0003] However, the device that simultaneously realizes fusion and embossing processes still needs to overcome a large number of problems during operation, such as the problem that the deflection of the foamed board causes the pattern to be inclined. The document of the authorized notification number CN208247834U discloses a foamed board embossing machine, including The body, the embossing mechanism and the traction mechanism arranged on the body, guide plates are arranged on both sides of the body, and the limit mechanism for limiting the position of the foam plate is arranged on the two guide plates. The chute perpendicular to the movement direction of the foam board, the two clamping parts slidingly connected with the chute and the driving mechanism that drives the two clamping parts to slide towards each other to clamp the foam board, and the side wall of the material guide plate is provided with Limit assembly to limit the position of the clamp

Although this device solves the problem of foam board offset to a certain extent, the cost of adding an additional traction mechanism and introducing a new motor is relatively high, and the device needs to be adjusted every time according to the width of the foam board. If it is too large, the offset distance will be too large to affect the pattern. If the adjustment is too small, it will be directly squeezed to both ends of the foam board, causing the film at both ends of the foam board to wear, so it is not suitable for the embossing process of PE-coated boards.
