Treatment process after hot melt adhesive preparation

Abstract

The invention relates to a treatment process after hot melt adhesive preparation, which uses a treatment machine after hot melt adhesive preparation. The machine comprises a workbench, supporting rods, an mounting frame and a film wrapping device, the supporting rods are evenly installed at the positions, close to the four corners, of the lower end face of the workbench, the mounting frame is installed in the middle of the upper end of the workbench, and the film wrapping device is arranged on the mounting frame. According to the treatment process after hot melt adhesive preparation, the problems that after an existing rod-shaped hot melt adhesive is prepared, the hot melt adhesive often needs to be subjected to film wrapping treatment, a traditional manual film wrapping method can cause poor film wrapping effect, the fitting degree between a film and the surface of the rod-shaped hot melt adhesive is not high, the conditions of bubbles, wrinkles and the like possibly occur, the quality of the hot melt adhesive is affected, and when an existing rod-shaped hot melt adhesive is subjected to film wrapping, the two ends of the hot melt adhesive are usually manually clamped for rotary film wrapping, the operation steps are tedious, the film wrapping force and speed need to be manually controlled, and manpower and material resources are wasted are solved.

Description

technical field [0001] The invention relates to the technical field of colloid preparation, in particular to a post-treatment process for hot melt adhesive preparation. Background technique [0002] Hot-melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless. It is an environmentally friendly chemical product. Since the hot-melt adhesive itself is a solid , so it is convenient for packaging, transportation and storage, and hot melt adhesive is a kind of non-polluting and non-toxic material, which has the advantages of simple production process, high added value, high bonding strength and fast speed, so it is widely used as a material for bonding Adhesives used directly. [0003] At present, after the hot-melt adhesive is prepared, there are usually the following defects: 1. After the existing rod-shaped hot-melt adhesive is prepare...

Problems solved by technology

[0005] The present invention can solve the problem that after the preparation of the existing rod-shaped hot-melt adhesive, it is often necessary to wrap the hot-melt adhesive with a film, but the traditional method of artificial film-wrapping will make the film-wrapping effect not good, and the surface of the film and the rod-shaped hot-melt adhesive The fit degree is not high, and it is more likely to have bubbles, wrinkles, etc., which will affect its quality, and when the existing rod-shaped hot-melt adhesive is wrapped, the two ends of the hot-melt adhesive are usually manually clamped to rotate the film, and the operation The steps are cumbersome, and it is necessary to manually control the strength and speed of the film, which wastes manpower and material resources, etc.
