Description
Technical Field
[0001] The utility model relates to the technical field of particle melting equipment, in particular to a plastic particle heating and melting equipment. Background Art
[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.
[0003] In the process of injection molding production, it is sometimes necessary to heat and melt the plastic particles. At present, the generally used heating and melting devices for injection molding plastic particles are mostly simple in structure. Since the plastic particles are of different sizes, they are directly put into melting without screening, which will result in different melting times, thereby easily reducing the overall melting speed of the plastic particles. Although some heating and melting equipment also has a filtering screen plate, as the feeding continues, large particles will cause the screen plate to clog. At this time, the particles on the screen plate need to be cleaned. If necessary, the screen plate even needs to be disassembled and replaced after cleaning. The screening operation continues, and the replacement is more troublesome, which reduces people's work efficiency. Utility Model Content

The material conditions in the feed bin can be observed in real time through the transparent observation windows, which makes it easier to control the operation of the hot melt machine according to the material conditions in the feed bin, which is more convenient.
