They have a wide range of uses. In the processing of plastic particles, in order to achieve the specified model, extrusion equipment is usually required. The plastic particles are heated and pressurized by the extrusion equipment to form a fluid and then extruded through a die to obtain the required shape.

[0003] When existing plastic particle extrusion equipment is used, it is usually used in conjunction with a lower hopper to feed plastic particles. Due to the granular shape of the plastic particle raw materials, in order to ensure the efficiency of plastic particle feeding, a large amount of plastic particles are often fed into the lower hopper each time, which makes it easy for plastic particles to accumulate in the lower hopper. In addition, if the plastic particles adhere to each other, the lower hopper will be blocked, resulting in the phenomenon that the plastic particles cannot be discharged, affecting the normal processing of the plastic particles entering the extrusion equipment and reducing the effectiveness of plastic particle discharge. Therefore, in order to solve the above problems, a plastic particle extrusion equipment is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-4 The plastic particle extrusion equipment shown includes an extrusion structure 100 and a lower hopper 300 fixedly arranged on the extrusion structure 100. The extrusion structure 100 includes an extrusion barrel 101, an extrusion rod 102 and a drive assembly. The extrusion rod 102 is movably arranged in the inner cavity of the extrusion barrel 101 through the drive assembly. The drive assembly is arranged at one end of the extrusion barrel 101. The drive assembly includes two synchronous wheels 103, a synchronous belt 104 and a drive motor 105. The synchronous belt 104 is driven between the two synchronous wheels 103, and the drive motor 105 is driven by one of the synchronous wheels 103.

[0023] Specific reference Figure 1 and Figure 2 The extrusion rod 102 is spiral, and one end of the extrusion rod 102 is fixed to the center of the other synchronous wheel 103. The two synchronous wheels 103 are distributed in the upper and lower positions. The bottom ends of the extrusion barrel 101 and the drive motor 105 are both equipped with a base plate, which is used to support the overall structure. The drive motor 105 is electrically connected to the external power supply through an external control switch. By starting the drive motor 105, one of the synchronous wheels 103 is driven to rotate. Under the drive of the synchronous belt 104, the other synchronous wheel 103 rotates synchronously, thereby driving the extrusion rod 102 to rotate, so that the plastic particles entering the extrusion barrel 101 can be extruded. The lower hopper 300 is fixedly installed on the top of the extrusion barrel 101, and the lower hopper 300 is connected to the inner cavity of the extrusion barrel 101, which is convenient for feeding plastic particles.

[0024] A movable structure 200 is provided inside the lower hopper 300, and the movable structure 200 includes a movable wheel 201, a support frame 202 and a stirring rod 204. The movable wheel 201 is movably provided in the inner cavity of the extrusion structure 100, and the support frame 202 is fixedly provided on the inner wall of the lower hopper 300. A movable rod 203 is movably provided in the center of the support frame 202, and the stirring rod 204 is fixedly provided on the movable rod 203. The stirring rod 204 is used to stir the plastic particles in the lower hopper 300. The movable wheel 201 is fixedly sleeved on the outer wall of the extrusion rod 102, and both ends of the movable rod 203 are arc-shaped. The movable structure 200 also includes a connecting groove 205 and a connecting rod 206. The connecting groove 205 is opened on the movable rod 203, and the connecting rod 206 is fixedly provided on the inner wall of the support frame 202. The connecting rod 206 and the inner cavity of the connecting groove 205 are movably provided.

[0025] Specific reference Figure 2 and Figure 3 The movable wheel 201 is an eccentric wheel, which is fixedly mounted on the outer wall of the extrusion rod 102 and rotates with the rotation of the extrusion rod 102. The movable rod 203 is installed above the movable wheel 201 through the support frame 202 and is located inside the lower hopper 300. The arc-shaped end of the movable rod 203 is convenient for vertical movement under extrusion. As the movable wheel 201 rotates, the movable rod 203 will be squeezed. The squeezed movable rod 203 will move upward along the center of the support frame 202. While moving, it is connected with the connecting groove 205 and the connecting rod 206. The connecting groove 205 is spirally opened on the outer wall of the movable rod 203, so that the movable rod 203 moves upward while rotating, and the stirring rod 204 is driven to rotate synchronously while rotating, so that the lower hopper 300 can be effectively controlled. 00 is stirred, the probability of plastic particles accumulating in the lower hopper 300 is reduced, and the smoothness and orderliness of plastic particle discharge are improved. At the same time, the plastic particles enter the lower hopper 300 or the plastic particles accumulated in the lower hopper 300 generate pressure on the movable rod 203. At the same time, when the movable wheel 201 rotates to a position where it does not squeeze the movable rod 203, the movable rod 203 will lower its position with the help of the pressure of the plastic particles, and rotate in the opposite direction while descending, and also stir the plastic particles in the lower hopper 300 to ensure the continuous discharge of plastic particles and improve the effectiveness and uniformity of plastic particle discharge. As a result, the phenomenon of plastic particles in the lower hopper 300 being blocked can be effectively avoided, so that the lower hopper 300 can be effectively fed and the extrusion quality of the plastic particles is improved.

[0026] The support frame 202 includes two concentric rings of different diameters and two rods. The two rods are fixedly arranged between the two concentric rings. The length of the stirring rod 204 is greater than the length of the rod.

[0027] Specific reference Figure 2 and Figure 4The setting of the support frame 202 can not only support the position of the movable rod 203, but also provide space for the discharge of plastic particles to avoid affecting the orderly discharge of plastic particles. At the same time, the length of the stirring rod 204 is greater than the length of the rod body and smaller than the outer ring radius of the support frame 202, so that the stirring rod 204 can stir the plastic particles as the movable rod 203 rotates, and can also move down the position of the movable rod 203 to prevent the movable rod 203 from falling directly into the extrusion barrel 101, which plays a certain limiting role on the movable rod 203 and ensures the effectiveness of repeated vertical movement of the movable rod 203.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
