Melting film equipment suitable for flexible polyurethane foam coils and method for realizing melting film based on the melting film equipment

Abstract

High-efficiency and safe melting film equipment for flexible polyurethane foam coils and its processing method. One of the existing foam blasting melt film technologies is to cut the rectangular foam blocks into coils after melting the film, which wastes man-hours and materials, and the surface pore size and physical properties of the unfolded coils are not uniform; The membrane reticulation coil is put into the melting film equipment of the rectangular container to melt the membrane reticulation, resulting in a waste of melting film space, deformation or damage of the coil; the existing equipment is simple and unfavorable to safe operation, process design and uniform distribution of blasting force. The method of the present invention includes: a circular pressure-resistant container (1), the circular pressure-resistant container is connected to a circular quick-opening upper door (3) through a circular chuck (2), and the circular quick-opening upper door is connected to a lift A translation device (4); wherein, the bottom of the circular pressure-resistant container is connected to a group of gas injection ports (5), and the circular quick-opening upper door is connected to a gas extraction port (6). The invention is used for reticulated foam processing.

Description

[0001] Technical field: [0002] The invention relates to a high-efficiency and safe melting film equipment for flexible polyurethane foam coils and a processing method thereof. [0003] Background technique: [0004] Existing production methods of reticulated foam coils: one is to use a rotary cutting device to cut off the four corners of the rectangular foam block after the melt film is reticulated to form a cylinder, and then perform spiral cutting. Gradually cut, the cylindrical foam block is cut into a super long thin sheet with use value, and then packed in rolls for storage and transportation. [0005] Another method is to cut the extra-long unmelted film reticulated rectangular foam block from top to bottom into super-long thin sheets of required thickness layer by layer, and then roll them into rolls, and then roll the rolls The material is put into the melting film equipment of the rectangular container for melting film reticulation treatment to obtain reticulated fo...

AI Technical Summary

Problems solved by technology

[0010] The present invention solves the problem that the blasting force at each point in the container is unevenly distributed when the existing circular foam coil is put into a rectangular melt film container and the melt film exists, which easily causes deformation and damage to the coil.
