Preparation method for polyethylene foamed cotton material

Abstract

The invention relates to a preparation method for a polyethylene foamed cotton material. A bottom plate, a placing device and a cutting device are included. The placing device is mounted at the upper end of the bottom plate, the cutting device is arranged above the placing device, and the cutting device is mounted on the upper end surface of the bottom plate. The preparation method can solve the problem that existing equipment does not have a function of processing foamed cotton boards of different dimensions on same equipment when the existing equipment forms U-shaped slots in the polyethylene foamed cotton boards, so that the adaptability of the equipment is improved, and meanwhile, the preparation method solves the problems that the using occasion of the equipment is reduced as the slotting depth cannot be adjusted, and the slotting effect of the foamed cotton boards is reduced as the surface of the cut position is not even as the foamed cotton boards are easily lifted up and the problems that the slotting shape is irregular as the cut slot wall cannot be leaned and limited and the slot wall which shrinks affects slotting.

Description

technical field [0001] The invention relates to the technical field of foamed plastic processing, in particular to a method for preparing polyethylene foamed cotton material. Background technique [0002] Polyethylene foamed cotton is a new type of environmentally friendly material. Polyethylene foamed cotton is non-toxic, odorless, sound-proof, sound-absorbing, heat-insulating, and has no pollution to the atmosphere when incinerated. It has good resilience and can adjust its hardness and thickness at will. Light weight and other characteristics, it is irreplaceable by other foamed cotton materials, can be hot-pressed, and can also produce flame-retardant type, suitable for sports protective gear, handbags, automobiles, aerospace, construction, shoe materials, toys, Air conditioning, oil pipeline insulation. [0003] At present, the existing equipment usually has the following deficiencies when opening U-shaped grooves for polyethylene foamed cotton boards: 1. The existing ...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that existing equipment cannot process foamed cotton boards of different sizes on the same equipment when opening U-shaped grooves for polyethylene foamed cotton boards, thereby improving the applicability of the equipment, and at the same time , the slotting depth cannot be adjusted, which reduces the use of the equipment. When cutting, the foamed cotton board is prone to lift off, resulting in uneven cutting surface, thus reducing the slotting effect of the foamed cotton board. , and it is not possible to tighten and limit the groove wall after cutting, and the shrinkage of the groove wall will affect the subsequent grooving, resulting in problems such as irregular groove shape
