Description

Technical Field

[0001] The utility model relates to the field of extruder equipment, and specifically relates to a four-color plastic extrusion die. Background Technique

[0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent plastic extrusion molding machine supporting it is called the auxiliary machine. After more than 100 years of development, the plastic extruder has evolved from the original single-screw to double-screw, multi-screw, and even screwless models. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, films, rods, monofilaments, flat filaments, packing straps, wire meshes, plates (sheets), profiles, granulation, and cable coating to form various plastic extrusion molding production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machine types in the plastic processing industry, both now and in the future. The existing extruder melts plastic particles and directly extrudes them through a screw. During the extrusion process, it does not have the function of filtering the extruded material, resulting in more impurities in the extruded material and affecting the product quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a four-color plastic extrusion die to solve the problem in the above background technique that the existing extruder melts plastic particles and directly extrudes them through a screw. During the extrusion process, it does not have the function of filtering the extruded material, resulting in more impurities in the extruded material and affecting the product quality.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a four-color plastic extrusion die, including an extrusion component and a filtering component;

[0005] Among them: the extrusion component includes a first extruder, a second extruder, a third extruder, and a fourth extruder. Extrusion screws are installed inside the first extruder, the second extruder, the third extruder, and the fourth extruder. One end of the first extruder, the second extruder, the third extruder, and the fourth extruder is connected to a discharge section. One end of the discharge section is connected to a connection section. One ends of the four connection sections are commonly connected to a four-color polymerization die body. One end of the four-color polymerization die body is connected to a die head.

[0006] The filtering component includes that one end of the discharge section and one end of the extruder body are both connected to a connection flange, and a filter screen is installed inside the connection flange.

[0007] As a preferred scheme of the utility model: the two connection flanges are fixedly connected by bolts.

[0008] As a preferred scheme of the utility model: heating coils are installed outside the discharge section, the connection section, the four-color polymerization die body, and the die head.

[0011] As a preferred embodiment of this utility model, a round-headed copper sleeve is provided at the connection between the discharge section and the connecting section.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) A connecting flange is connected to one end of the discharge section and one end of the extruder. The connecting flanges are fixedly connected by bolts. A filter screen is installed inside the connecting flange. The filter screen filters the extruded material to remove impurities and then squeezes it towards the discharge section. The filtered material is then conveyed to the connecting section through the discharge section. The filtered extruded material greatly reduces internal impurities, thus ensuring the quality of the subsequent extruded products.

[0014] (2) Through the provided extrusion assembly, through the provided first extruder, second extruder, third extruder and fourth extruder, extrusion screws are installed inside the four extruders. The molten plastic is extruded through the extrusion screws. The extruded material is conveyed through the discharge section. One end of the discharge section is connected to a connecting section. The four connecting sections are connected to the surface of the four-color polymerization mold, so that the four-color polymerization mold is extruded and polymerized at the same time. Finally, the four colors are extruded through the die to form a solid plastic bar with four colors evenly distributed. Attached Figure Description
