Description

Technical Field

[0001] The utility model relates to the technical field of plastic particles, and particularly to an intelligent temperature-controlled plastic particle melting and extrusion device. Background Technique

[0002] The raw materials used for plastic molding in industry mainly include powder materials, granular materials, solutions and dispersions. In some molding processes, monomers and prepolymers are used. The powder materials and granular materials are more widely used. The powder materials are prepared by uniformly mixing and dispersing powdery raw material resins and various different additives. The granular materials are obtained by plastifying the powder materials through plastification operations and making them into mixed granular materials by different methods.

[0003] In the prior art, for example, Chinese Patent Publication No. CN221339487U discloses a screw extruder for particle production, which includes a bottom plate. One side of the top of the bottom plate is provided with a drive box. One end of the drive box is provided with a feeding assembly. The feeding assembly includes a feeding sleeve arranged at one end of the drive box. The middle of the top of the bottom plate is provided with an extrusion mechanism connected to the feeding assembly. The other side of the top of the bottom plate is provided with a cooling assembly connected to the extrusion mechanism. Both ends of both sides of the bottom of the bottom plate are provided with moving support assemblies, which can realize the efficient melting and extrusion process of plastic raw materials, improve the production efficiency of particles. The feeding assembly ensures the smooth feeding and conveying of plastic raw materials. The extrusion mechanism extrudes the molten plastic raw materials into continuous particle extrusion strips through heating and extrusion. The cooling assembly is used to cool and solidify the extruded particle extrusion strips, providing reliable equipment support for particle production.

[0004] However, in the existing plastic particle extrusion equipment, the heated molten plastic is usually put into an extruder, extruded into strips, then water-cooled, and then cut into particles by another device. Therefore, in the actual production of plastic particles, two devices are required to complete the process, resulting in a high space cost and easy contamination with dust and debris during transportation, and the molding quality of plastic particles is low. In view of this, we propose an intelligent temperature-controlled plastic particle melting and extrusion device. Content of the Utility Model

In this way, the cutting blade 23 can move back and forth along the chute 25 to realize the cutting of the extruded plastic particles.

[0023] Please refer to Figure 1 As shown in the figure, in this embodiment, a cooling box 12 is fixedly connected to the side of the cutting frame 2 away from the storage bin 11. An extrusion head 13 is movably connected to the side of the cooling box 12 close to the cutting frame 2. The extrusion head 13 can be replaced with different models according to production requirements, so that the device can adapt to the production of plastic particles with different shapes and specifications, enhancing the flexibility and versatility of the device.

[0024] Please refer to Figure 3 As shown in the figure, further, a extrusion barrel 14 is fixedly connected to the side of the cooling box 12 away from the cutting frame 2. A rotating shaft 42 is arranged in the inner cavity of the extrusion barrel 14. A spiral conveying blade 15 is fixedly connected to the surface of the rotating shaft 42.

Then start the second motor 4, which drives the spiral conveying blade 15 on the surface of the rotating shaft 42 to rotate. The material is transported to the cooling box 12 through the spiral conveying blade 15. When passing through the cooling box 12, the material will form a softer solid, which is convenient for extrusion. Then start the electric push rod 41 to push the movable push plate 43 and seal the feeding port 31 with the sealing cover 32. During the process of the electric push rod 41 pushing the movable push plate 43, the material is extruded from the extrusion head 13 through the internal air pressure. The extrusion head 13 can be replaced according to the shape of the material to be produced. When the material is extruded, the first motor 21 drives the threaded rod 22 to rotate, so that the cutting blade 23 cooperates with the slider 24 at the bottom to move back and forth, achieving the effect of cutting the extruded material. During the cutting process, the back-and-forth movement speed can be adjusted to cut the material into the required length. The cut material enters the storage box 11.
