[0002] Plastic granulation is a process in plastic mechanical processing. In the process of plastic granulation, it is necessary to explore and master the skills based on the performance of the machine and practical experience in order to continuously improve the quality and process of plastic products.

[0003] Currently, in the plastic granulation process, the material needs to be stirred and preheated before entering the screw extruder. However, the agitator inside the feeding hopper comes into contact with the raw material, which can cause the material to stick and clump together, making it difficult to clean. In addition, the operating space for the agitator inside the feeding hopper is small, which increases the difficulty of maintaining the agitator. Utility Model Content

[0004] The purpose of this invention is to provide a plastic granulation mixing device to solve the problem of inconvenient maintenance of the internal agitator of the feeding hopper mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic granulation and mixing device, including a screw extruder, a feeding hopper provided on the top of the screw extruder, a heater provided in the inner jacket of the feeding hopper, and a sealing assembly provided on the top of the screw extruder;

[0006] The sealing assembly includes a fixed plate fixed to the top of the screw extruder, a sealing strip with a ring structure on the inner side of the fixed plate, a feeding hopper inserted inside the sealing strip, the bottom of the feeding hopper corresponding to the opening position at the top of the screw extruder, and an agitator rotatably connected inside the feeding hopper.

[0007] Preferably, a fixing frame is fixedly connected to the top side of the screw extruder, and the fixing frame has an "L" shaped structure.

[0008] Preferably, a drive motor is mounted on the top of the fixed frame, and a stirrer is rotatably connected to the bottom of the fixed frame, with the top of the stirrer connected to the shaft of the drive motor.

[0009] Preferably, the sealing strip has through holes on both sides, and a connecting block is inserted into the through holes. The feeding hopper has grooves on both sides, and the grooves correspond to the positions of the through holes. One end of the connecting block is inserted into the groove of the feeding hopper.

[0010] Preferably, a screw is threadedly connected to the fixing plate, and one end of the screw is rotatably connected to the connecting block.

[0011] Preferably, a connecting rod is fixedly connected to the top side of the feeding and processing hopper, and multiple through holes are longitudinally opened on the connecting rod, with one end of the connecting rod inserted into the fixed frame.

[0012] Preferably, one end of the fixing frame is threaded with a locking bolt, and one end of the locking bolt passes through the fixing frame and is connected to the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device facilitates the cleaning and maintenance of the feeding hopper and agitator, thereby ensuring the hygiene of the feeding hopper and agitator.

[0015] (2) This device separates the feeding hopper from the screw extruder and installs the agitator inside the feeding hopper while connecting one end of the agitator to the fixed frame. This allows the feeding hopper to be separated from the screw extruder and the agitator to be fully exposed, making it easier to clean the agitator and the feeding hopper separately and reducing the difficulty of cleaning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a plastic granulation and mixing device, including a screw extruder 7, a feeding hopper 6 on the top of the screw extruder 7, and a fixed frame 2 fixedly connected to the top side of the screw extruder 7. The fixed frame 2 has an "L" shaped structure; this fixed frame 2 can ensure the stable installation of the drive motor 1; the drive motor 1 is installed on the top of the fixed frame 2, and an agitator 4 is rotatably connected to the bottom of the fixed frame 2. The top of the agitator 4 is connected to the shaft of the drive motor 1; this structure can drive the agitator 4 to rotate automatically through the drive motor 1, so that the agitator 4 can stir and heat the raw materials;

[0023] A heater 8 is installed in the inner jacket of the feeding hopper 6, and a sealing assembly 9 is installed on the top of the screw extruder 7;

[0024] The sealing assembly 9 includes a fixing plate 93 fixed to the top of the screw extruder 7. A screw 92 is threaded onto the fixing plate 93, and one end of the screw 92 is rotatably connected to a connecting block 91. This structure allows the connecting block 91 to move by rotating the screw 92, enabling it to connect or separate from the feeding hopper 6. A connecting rod 5 is fixedly connected to the top side of the feeding hopper 6. The connecting rod 5 has multiple through holes longitudinally opened, and one end of the connecting rod 5 is inserted into the fixing frame 2. This structure allows the height of the feeding hopper 6 to be adjusted by moving the connecting rod 5. When the feeding hopper 6 is raised, it can be separated from the agitator 4, facilitating separate cleaning of the agitator 4 and the feeding hopper 6, and providing a larger operating space. A locking bolt 3 is threaded onto one end of the fixing frame 2, and one end of the locking bolt 3 passes through the fixing frame 2 and connects to the connecting rod 5. This structure allows the feeding hopper 6 to be connected to the top side of the feeding hopper 6 by moving the connecting rod 5. Bolt 3 can lock or separate the fixing frame 2 and the connecting rod 5; a sealing strip 94 is provided on the inner side of the fixing plate 93, and through holes are opened on both sides of the sealing strip 94. A connecting block 91 is inserted into the through holes. Grooves are opened on both sides of the feeding hopper 6, and the grooves correspond to the positions of the through holes. One end of the connecting block 91 is inserted into the groove of the feeding hopper 6. This structure, through the connection of the connecting block 91 and the feeding hopper 6, can ensure the stability of the connection between the feeding hopper 6 and the screw extruder 7; the sealing strip 94 has a ring structure, and the feeding hopper 6 is inserted into the sealing strip 94. The bottom of the feeding hopper 6 corresponds to the opening position of the top of the screw extruder 7. An agitator 4 is rotatably connected inside the feeding hopper 6; this device can ensure the sealing of the gap between the screw extruder 7 and the feeding hopper 6 when the screw extruder 7 is connected to the feeding hopper 6 through the sealing strip 94.

[0025] Working principle: When using this plastic granulation mixing device, the raw material is first added to the feeding hopper 6 and heated by the heater 8. During the heating process, the agitator 4 stirs the raw material. Then, the raw material enters the screw extruder 7 for the next processing step. If it is necessary to clean the feeding hopper 6 and the agitator 4, the screw 92 is rotated while the machine is stopped, so that the connecting block 91 at one end of the screw 92 is separated from the outer wall of the feeding hopper 6. Then, the locking bolt 3 is loosened and the feeding hopper 6 is pushed upward, so that the connecting rod 5 on the top side of the feeding hopper 6 slides on the fixed frame 2. When the feeding hopper 6 is at a suitable height, the locking bolt 3 is rotated to fix the connecting rod 5 to the fixed frame 2, and the feeding hopper 6 and the agitator 4 can be cleaned. After the cleaning is completed, the feeding hopper 6 and the connecting block 91 are reset in sequence.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
