[0002] PC plastic is a polymer material with excellent mechanical, thermal, and electrical properties, and is widely used in the automotive, electronics, and medical fields. During the production and molding process of PC plastic, an extrusion device is required, and a screw extruder is generally used for plastic extrusion.

[0003] When a screw extruder is in use, plastic pellets in the hopper enter the extrusion tube, where they are heated and melted before being extruded. However, in existing screw extruders, the hopper is fixed to the extrusion tube. During the unloading process, the hopper remains stationary, relying solely on gravity for unloading. This can easily lead to blockage, which in turn affects the normal unloading process. Furthermore, the heating structure installed in the extrusion tube is an integral structure, making it difficult to disassemble and replace. If damaged, the entire structure must be replaced, which is extremely inconvenient and increases replacement costs. Utility Model Content

The bottom plate 8 is provided at the lower end of the base 1, a screw is provided inside the extrusion tube 2, and the screw is connected to the transmission gear inside the transmission box 4, and an extrusion end 6 is provided at the end of the extrusion tube 2. The heating structure 7 also includes a connecting rod 703, a mounting bolt 704, a terminal 705 and an electrical connection component 706. The connecting rod 703 is fixed to the first heating plate 701 and the second heating plate 702. The mounting bolt 704 runs through the connecting rod 703, and the end of the mounting bolt 704 is provided with a mounting nut. The terminal 705 is fixed. The first heating plate 701 and the second heating plate 702 are fixed, and the electrical connection component 706 is connected to the terminal 705. The electrical connection component 706 includes a connecting column 7061, a metal column 7062, a merging rod 7063, a terminal block 7064 and a fixing knob 7065. The connecting column 7061 is fixedly connected to the metal column 7062, and the metal column 7062 is plugged into the terminal 705. The merging rod 7063 is connected to the connecting column 7061, and the terminal block 7064 is fixed to the merging rod 7063. The terminal block 7064 is threadedly connected to the fixing knob 7065, and multiple heating structures 7 are arranged on the outside of the extrusion tube 2. The heating structure 7 is installed using mounting bolts 704, which is convenient for disassembly. The multiple heating structures 7 are independently arranged. When one of them is damaged, it only needs to be disassembled and replaced separately. There is no need to replace other heating structures 7, which reduces the replacement cost and improves the convenience of operation. An electrical connection component 706 is set on the terminal 705 to merge the circuits and reduce the connection of cables.

[0022] When using the extrusion device, the base 1 in the device is placed on the ground, and the bottom plate 8 is used in conjunction with the ground nails to ensure the stability of the device. A heating structure 7 is set on the extrusion tube 2. During installation, the first heating plate 701 and the second heating plate 702 are put on the extrusion tube 2, and the connecting rod 703 is fixed by using the mounting bolts 704 in conjunction with the mounting nuts, so that the two heating plates are fixed to the extrusion tube 2. Then, the electrical connection component 706 is connected, and the metal column 7062 at the lower end of the connecting column 7061 is plugged into the terminal 705. The corresponding terminal 705 is electrically connected to the terminal block 7064 on the merging rod 7063 through the metal column 7062. The cable is connected to the terminal block 7064 and the fixing knob is used. 7065 is fixed, so that the heating structure 7 is connected to the power supply, and then plastic particles are poured into the feeding structure 5. After starting the motor 3, the motor 3 drives the screw inside the extrusion tube 2 to run through the transmission gear inside the transmission box 4. After the plastic particles in the feeding structure 5 fall into the extrusion tube 2, the screw moves slowly with the plastic particles. When the particles move to the heating structure 7, the heating structure 7 melts the plastic particles into liquid. As the transportation continues, the liquid plastic cools down and is finally extruded and formed from the extrusion end 6, thus realizing the extrusion of the plastic. In this process, multiple heating structures 7 are used independently. When one of them is damaged, only the corresponding heating structure 7 needs to be disassembled and replaced.

[0023] According to the above embodiment, the feeding structure 5 includes a fixed pipe 501, a first connecting plate 502, a hopper 503, a second connecting plate 504, a cannula 505 and an elastic component 506. The fixed pipe 501 is fixedly connected to the first connecting plate 502, the hopper 503 is fixedly connected to the second connecting plate 504, the cannula 505 is installed at the lower end of the hopper 503, and the cannula 505 is connected in the fixed pipe 501. The elastic component 506 is located between the first connecting plate 502 and the second connecting plate 504. The feeding structure 5 also includes a connecting bolt 507. The first connecting plate 502 and the second connecting plate 504 are provided with circular holes. The connecting bolt 507 passes through the circular holes on the first connecting plate 502 and the second connecting plate 504, and the connecting bolt 507 passes through the elastic component 506. , a connecting nut is provided at the lower end of the connecting bolt 507, and the elastic component 506 includes a first clamping plate 5061, a second clamping plate 5062 and a spring 5063, and the ends of the spring 5063 are fixedly connected to the first clamping plate 5061 and the second clamping plate 5062 respectively, and the first clamping plate 5061 and the second clamping plate 5062 are provided with through holes. Through the setting of the feeding structure 5, a plug 505 is provided at the lower end of the hopper 503 and connected to the fixed pipe 501, and an elastic component 506 is arranged between the two connecting plates. During the operation of the device, due to the action of the elastic component 506, the hopper 503 has a certain degree of shaking, and then it can cause the material inside the hopper 503 to vibrate, which can effectively avoid the occurrence of blockage and ensure the normal progress of the unloading work.

[0024] When installing the feeding structure 5, the insert tube 505 at the lower end of the hopper 503 is inserted into the fixed tube 501, and an elastic component 506 is set between the first connecting plate 502 and the second connecting plate 504, so that the first clamping plate 5061 and the second clamping plate 5062 contact the first connecting plate 502 and the second connecting plate 504 respectively, and the connecting bolt 507 is passed through the two connecting plates and the elastic component 506, and the connecting nut is installed at the end of the connecting bolt 507, so that the hopper 503 is installed.
