Description

A hot-melt adhesive granulation extrusion device

technical field

The utility model relates to a hot-melt glue granulation device used in the granulation production link, which can be widely used in the production and packaging process.

Background technique

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, so it is often used in the field of production and processing. Due to the requirements of melting equipment, hot melt adhesives need to be made into solid shapes such as blocks, strips, and granules for easy transportation and use.

The working principle of the existing extrusion pelletizing system: the raw material of hot melt adhesive is made into a liquid product by heating the reactor, and then enters the gear pump through the filter, and the gear pump is transported forward to the extrusion nozzle by centrifugal force, and becomes a soft rubber close to the softening point The shape of the strip, the strip enters the cooling water tank and drops to the normal temperature to fix the shape, and then enters the granulator for granulation, and then completes the drying and packaging processes.

The traditional extrusion and granulation system is mainly completed by large-scale complete sets of equipment, which covers a large area, requires a large amount of capital investment, and has a large production capacity, which puts a lot of financial pressure on new entrants to small and medium-sized enterprises, and the equipment has a high idle rate.

Utility model content

The utility model provides a hot-melt glue extruding pelletizing device with simple structure, small occupied area, and reduced production and equipment costs.

The technical scheme of the utility model is achieved in that:

A hot-melt adhesive granulation extrusion device, including an extruder, an extrusion die, a cooling water tank, a pelletizer and a breathable collection basket, wherein the extrusion die is arranged at the side end above the extruder, and the cooling water tank is arranged It is fixed between the extruder and the pelletizer, and the air-permeable collection basket is fixed at the output end of the pelletizer.

The hot-melt adhesive pelletizing and extruding device provided by the utility model simplifies the hot-melt adhesive pelletizing device, and has the advantages of less cost investment, less floor space, easy disassembly, and less energy consumption, so that new entrants and new projects Easier to implement and implement.
