Description

Technical Field

[0001] This application relates to the technical field of plastic pellet mixing, and in particular to a plastic pellet mixer that facilitates unloading. Background Technology

[0002] Plastic granule mixing is a crucial step in plastic processing. It involves uniformly mixing plastic granules of different types, colors, or properties to ensure the consistency of the final product's performance. For example, in the production of colored plastic products, masterbatch needs to be thoroughly mixed with base plastic granules to achieve a uniform color. This also ensures that the plastic granules are in full contact with and evenly dispersed with various additives (such as plasticizers, stabilizers, and flame retardants), thereby improving the plastic's processing and performance characteristics. For instance, adding flame retardants can enhance the fire resistance of plastics.

[0003] A search revealed Chinese Patent Publication No. CN 220940538 U, which discloses a mixer for easy unloading. The mixer includes a base, a mixing drum, a collection box, and two support plates. Both support plates are fixedly connected to the base. Two threaded posts are fixedly connected to the upper surface of the mixing drum, and a top cover is movably contacted on the upper surface. Rotary shafts are fixedly connected to both ends of the side surface of the mixing drum. Each rotating shaft has a through hole on its side. Circular grooves are formed on the opposite sides of the two support plates. A limiting groove is formed on the front surface of each support plate. Each circular groove communicates with a nearby limiting groove and a nearby through hole. Each rotating shaft is rotatably connected to a nearby support plate via a circular groove. This device allows agricultural products to be automatically unloaded again through the feed inlet after mixing, improving operational convenience.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: existing mixers rely on scrapers to remove materials during unloading. However, when using the scrapers, materials tend to adhere to their surface, resulting in incomplete unloading and requiring manual secondary cleaning. This not only increases labor costs but also increases the intensity of manual labor. Utility Model Content

[0006] This application provides a plastic granule mixer for easy unloading, which adopts the following technical solution: It includes a bottom frame, a bottom support plate rotatably mounted on the outer side of one end of the bottom frame via a rotating rod, a track fixedly mounted on the middle of the upper surface of the bottom support plate, a pulley frame slidably mounted on the upper surface of the track, a top plate fixedly mounted on the top of the pulley frame, a mixing tank fixedly mounted on the middle of the upper surface of the top plate, a side fixing plate fixedly mounted on the left end of the top plate, an extension rod rotatably mounted on the middle of the front of the side fixing plate via a rotating groove, an eccentric wheel rotatably mounted on the end of the extension rod away from the side fixing plate via a rotating rod, the middle of the eccentric wheel fixedly sleeved on the outer side of the output shaft on one side of the motor, a vertical plate fixedly mounted on the bottom of the motor, the bottom of the vertical plate fixedly mounted on the upper surface of a support plate, a hydraulic rod fixedly mounted on the bottom of the support plate, and the bottom of the hydraulic rod fixedly mounted on the middle of the upper surface of one end of the bottom frame.

[0007] Sliding plates are fixedly installed at both ends of the upper surface of the pallet. A horizontal shaft is slidably inserted into the middle of the sliding plate. A slider is fixedly installed at the end of the horizontal shaft away from the sliding plate. The end of the slider away from the horizontal shaft is slidably installed on the inner wall of the groove on the inner side of the column. The bottom of the inner side of the column is fixedly installed on the outer side of one end of the bottom frame.

[0008] Optionally, two bottom support plates are provided, located on both sides of the bottom frame, with the inner side of the bottom support plates away from the outer side of the bottom frame.

[0009] Optionally, a tail baffle is fixedly installed at the end of the top plate. The front of the tail baffle is fixedly connected to the bottom of the mixing tank, and the middle part of the tail baffle near the bottom is connected to the discharge switch of the mixing tank.

[0010] Optionally, a cover plate is fitted onto one end of the mixing tank, and a stirring shaft is fixedly installed in the middle of the cover plate. Stirring rods are evenly arranged on the outer surface of the end of the stirring shaft away from the cover plate, and a groove is provided in the middle of the end of the stirring shaft at one end of the cover plate.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This invention incorporates components such as a top plate, pulley frame, eccentric wheel, and extension rod. The eccentric wheel, driven by a motor, causes one end of the extension rod to move in an arc. With the extension rod length fixed, the top plate wobbles back and forth, allowing the entire mixing tank to sway during unloading. This shaking helps all the plastic particles inside fall out, eliminating the need for secondary manual cleaning and improving unloading efficiency.

[0016] This invention incorporates components such as a hydraulic rod, a sliding plate, and a slider. The hydraulic rod drives the support plate to change its vertical position, thereby altering the tilt angle of the upper mixing tank. This facilitates the placement of different quantities of materials, prevents splashing during mixing, and ensures that the plastic granules are not lost during mixing. Furthermore, changing the angle of the mixing tank allows the plastic to fall more smoothly, preventing material accumulation inside. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a plastic pellet mixer that facilitates unloading. For example... Figure 1As shown, it includes a bottom frame 1. A bottom support plate 2 is rotatably mounted on the outer side of one end of the bottom frame 1 via a rotating rod. There are two bottom support plates 2, which are located on both sides of the bottom frame 1. The inner side of the bottom support plate 2 is away from the outer side of the bottom frame 1. The bottom support plates 2 are rotatably mounted on both sides of the bottom frame 1, so that the bottom support plates 2 and the top plate 4 above can change their angles.

[0024] Please see Figure 1 A track 3 is fixedly installed in the middle of the upper surface of the bottom support plate 2. A pulley frame 20 is slidably installed on the upper surface of the track 3. A top plate 4 is fixedly installed on the top of the pulley frame 20. A tail baffle 5 is fixedly installed at the end of the top plate 4. The front of the tail baffle 5 is fixedly connected to the bottom of the mixing tank 6. The middle part of the tail baffle 5 near the bottom is connected to the discharge switch of the mixing tank 6. The tail baffle 5 supports the bottom of the mixing tank 6 to prevent the mixing tank 6 from falling off the top plate 4.

[0025] Please see Figure 1 and Figure 2 A mixing tank 6 is fixedly installed in the middle of the upper surface of the top plate 4. A cover plate 9 is sleeved on one end of the mixing tank 6, and the cover plate 9 seals and covers one end of the mixing tank 6. A stirring shaft 10 is fixedly installed in the middle of the cover plate 9. Stirring rods are evenly arranged on the outer surface of the end of the stirring shaft 10 away from the cover plate 9. The stirring shaft 10 can be picked up by moving the cover plate 9, so that plastic granules can be put into it after the stirring shaft 10 is taken out. A groove is provided in the middle of the end of the stirring shaft 10 at the cover plate 9. The groove at the end of the stirring shaft 10 can be easily engaged with the output shaft of an external motor. The stirring shaft 10 rotates under the action of the external motor.

[0026] Please refer to the previous reading. Figure 1 A side fixing plate 7 is fixedly installed on the left end of the top plate 4. An extension rod 8 is rotatably installed on the center of the front of the side fixing plate 7 through a rotating groove. An eccentric wheel 12 is rotatably installed on the end of the extension rod 8 away from the side fixing plate 7 through a rotating rod. The connection position between the eccentric wheel 12 and the extension rod 8 is located at the edge of the eccentric wheel 12. By connecting the extension rod 8 to the edge of the eccentric wheel 12, one end of the extension rod 8 can swing back and forth when the eccentric wheel 12 rotates. The extension rod 8 is a long rod with threads on both ends. A threaded sleeve is threadedly fitted in the middle of the extension rod 8. The length of the extension rod 8 of the cover plate 9 is changed by the rotation of the threaded sleeve, thereby changing the movement range of the side fixing plate 7. The middle of the eccentric wheel 12 is fixedly fitted to the outside of the output shaft on one side of the motor 11. A vertical plate 16 is fixedly installed at the bottom of the motor 11. The bottom of the vertical plate 16 is fixedly installed on the upper surface of the support plate 17.

[0027] Please see Figure 1Two identical sliding rods 22 are fixedly installed at both ends of the bottom of the support plate 17. The bottom of the sliding rods 22 is fixedly installed at one end of the upper surface of the bottom frame 1. The sliding rods 22 are installed at both ends of the bottom of the support plate 17. Under the action of the sliding rods 22, the support plate 17 is more stable when moving up and down. The width of the support plate 17 is the same as the width of the column 19. One side of the support plate 17 is away from the outer side of the side plate 21. A hydraulic rod 18 is fixedly installed at the bottom of the support plate 17. The bottom of the hydraulic rod 18 is fixedly installed at the middle of the upper surface of one end of the bottom frame 1.

[0028] Please see Figure 1 Sliding plates 14 are fixedly installed at both ends of the upper surface of the support plate 17. A support shaft 23 is rotatably inserted into the right end of the sliding plate 14. The two ends of the support shaft 23 are fixedly installed on the inner wall of the power groove at both ends of the side plate 21. The right side of the side plate 21 is fixedly installed on the left end of the two bottom support plates 2. The sliding plate 14 is rotatably installed on the outside of the support shaft 23 at both ends of the side plate 21. When the sliding plate 14 drives the side plate 21 to move up and down, motion conflict is avoided. A horizontal shaft 15 is slidably inserted into the middle of the sliding plate 14. A slider 13 is fixedly installed at the end of the horizontal shaft 15 away from the sliding plate 14. The end of the slider 13 away from the horizontal shaft 15 is slidably installed on the inner wall of the groove on the inner side of the column 19. The bottom of the inner side of the column 19 is fixedly installed on the outside of one end of the bottom frame 1.

[0029] The implementation principle of a plastic granule mixer for easy unloading according to an embodiment of this application is as follows: During use, the cover plate 9 is removed from the inlet of the mixing tank 6, and the plastic granules to be mixed are poured into the mixing tank 6. The cover plate 9 is then placed over one end of the mixing tank 6. An external motor is connected to one end of the mixing shaft 10. Under the action of the external motor, the mixing shaft 10 rotates inside the mixing tank 6, achieving the mixing of the plastic granules. When mixing is complete, the discharge switch at the bottom right end of the mixing tank is opened. Simultaneously, the hydraulic rod 18 is activated, causing the upper support plate 17 to move upwards. Under the action of the sliding plate 14, the side plate 21 also rises. The side plate 21 causes one end of the bottom support plate 2 to rise, changing the angle between the bottom support plate 2 and the upper mixing tank 6, facilitating material unloading. If some plastic granules are not unloaded... The starter motor 11 drives the eccentric wheel 12 to rotate. The eccentric wheel 12 drives one end of the extension rod 8 to make a circular motion. With the length of the extension rod 8 fixed, the side fixing plate 7 and the bottom support plate 2 on one side move back and forth. Under the action of the high-speed rotation of the motor 11, the bottom support plate 2 drives the upper mixing tank 6 to move back and forth quickly, causing the plastic particles inside to shake, thereby completely unloading the plastic particles inside without the need for secondary cleaning.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
