Description

Technical Field

[0001] This utility model relates to the field of plastic mixing equipment technology, and more specifically, to a plastic granule mixer with automatic feeding capability. Background Technology

[0002] Plastic granules are a type of granular plastic. During production, various plastic granules can be mixed and stirred to form a mixed raw material. Plastic granule mixing and stirring machines are a common processing equipment used to mix different types or colors of plastic granules to produce specific plastic products. However, existing equipment has certain problems in use and still needs continuous improvement.

[0003] A search revealed that patent publication number CN219686202U discloses a plastic granule mixing and stirring device, including a base with two support seats mounted on the upper surface of the base. A mixing chamber is rotatably mounted between the two support seats. A motor is fixed to one side of each support seat; a tray is fixed to one side of each support seat, and a lead screw is rotatably mounted on the upper surface of the tray. A ball nut is threaded onto the surface of the lead screw, and a cover plate is fixed to one side of the ball nut. A second motor is fixed to the lower surface of the tray. Two guide rods are fixed to the upper surface of the base, allowing the cover plate to be raised and lowered. This keeps the mixing chamber clean and tidy, facilitating subsequent cleaning of residual material on the inner wall. The cover plate can also be automatically raised and lowered by the second motor, eliminating the need for manual opening and closing, reducing labor costs. After mixing, the first motor can drive the mixing chamber to rotate, allowing for rapid discharge of the mixed granules, improving mixing efficiency. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When in use, the device is operated by manually pulling the handle, which causes the I-shaped slider to move the scraper in the mixing chamber to clean the inner wall of the mixing chamber. During long-term use, the scraper will wear down, and in order to ensure the scraper's performance, it needs to be replaced regularly. However, the I-shaped slider and the scraper are fixedly connected, making it inconvenient to disassemble and replace the scraper.

[0005] Therefore, a plastic pellet mixer with automatic feeding capability is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic granule mixer with automatic feeding capability to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding plastic granule mixer, comprising a base, two support seats symmetrically welded to the upper surface of the base, a mixing chamber fixedly connected between the two support seats, a set of connecting seats on both sides of the mixing chamber, a lead screw rotatably connected in each set of connecting seats, a moving plate threaded on the outer side of the two lead screws, a fixed plate welded to the moving plate, a plurality of insertion holes equally spaced on the surface of the fixed plate, a scraper provided below the fixed plate, a limit plate welded to the surface of the scraper, a plurality of insertion rods equally spaced through the surface of the limit plate and connected to the insertion holes, a stop block fixedly connected to the outer side of the insertion rods, and a compression spring sleeved on the outer side of each of the insertion rods.

[0008] Preferably, the compression spring is disposed between the stop block and the limiting plate, and both ends of the compression spring are fixedly connected to the stop block and the limiting plate respectively, and one end of several of the insert rods is connected to a pulling rod for pulling the insert rods.

[0009] Preferably, a discharge port is provided at the bottom of one end of the mixing chamber, and a cover plate is provided at the top of the mixing chamber. A connecting block is fixedly welded to both ends of the cover plate. A fixing block is welded to the back of each of the two support seats. A cylinder is installed on each of the two fixing blocks, and the output ends of the two cylinders are connected to the connecting blocks.

[0010] Preferably, a main stirring shaft is rotatably connected to the cover plate, and two driven stirring shafts are rotatably connected to the cover plate on both sides of the main stirring shaft. Stirring rods are fixedly installed on the outer side of the main stirring shaft and the two driven stirring shafts.

[0011] Preferably, two pulleys are provided on the outer side of the upper end of the main stirring shaft, and one pulley is provided on the outer side of the upper end of each of the two driven stirring shafts. The two pulleys on the main stirring shaft and the pulleys on the two driven stirring shafts are respectively connected by a transmission belt.

[0012] Preferably, a drive motor is bolted to the upper surface of the cover plate, and the drive motor is connected to one end of the main stirring shaft via a coupling.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the existing technology, by squeezing the stop block fixedly connected to the outside of the insertion rod by the compression spring, the stop block moves upward. The upward movement of the stop block drives the insertion rod to move closer to the fixed plate, so that multiple insertion rods are inserted into multiple insertion holes opened on the surface of the fixed plate, thereby completing the limiting connection between the moving plate and the scraper. The setting of this structure can quickly and conveniently realize the installation, use and disassembly of the scraper, improving the practicality of the device.

[0015] 2. Compared with the existing technology, by simultaneously connecting the lead screw and the moving plate by thread, the rotating lead screw can drive the moving plate, thereby causing the moving plate to drive the scraper to scrape off the plastic particles attached to the inner wall of the mixing chamber, and at the same time push the plastic particles that have been mixed in the mixing chamber, so that the plastic particles can be discharged from the discharge port set at the bottom of one end of the mixing chamber.

[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] Example 1

[0023] As attached Figures 1 to 4The illustrated automatic feeding plastic pellet mixer includes a base 1. Two support seats 2 are symmetrically welded to the upper surface of the base 1. A mixing chamber 3 is then fixedly connected between the two support seats 2. A set of connecting seats 5 is provided on both sides of the mixing chamber 3. A lead screw 6 is rotatably connected to each set of connecting seats 5, and a servo motor is bolted to each set of connecting seats 5. The servo motor is connected to one end of the lead screw 6 via a coupling, allowing the servo motor to drive the lead screw 6 to rotate. A movable plate 7 is threaded onto the outer side of both lead screws 6. The movable plate 7 is welded with… A fixed plate 8 is attached, and a number of insertion holes 9 are evenly spaced on the surface of the fixed plate 8. A scraper 10 is provided below the fixed plate 8. A limit plate 11 is welded to the surface of the scraper 10. A number of insertion rods 23 that are inserted and connected to the insertion holes 9 are evenly spaced on the surface of the limit plate 11. A stop block is fixedly connected to the outside of the insertion rods 23. A compression spring 13 is sleeved on the outside of each insertion rod 23. The compression spring 13 is located between the stop block and the limit plate 11, and both ends of the compression spring 13 are fixedly connected to the stop block and the limit plate 11, respectively. A pulling rod 12 that pulls the insertion rods 23 is connected to one end of each insertion rod 23.

[0024] In operation, the device is powered by a servo motor driving a lead screw 6 to rotate. This rotation, via the screw 6, drives a moving plate 7 and a scraper 10 connected to the moving plate 7 to move within the mixing chamber 3. The scraper 10 scrapes away plastic particles adhering to the inner wall of the mixing chamber 3 and simultaneously pushes the mixed plastic particles within the mixing chamber 3, facilitating their discharge from the discharge port 4 at one end of the mixing chamber 3. When the scraper 10 needs to be disassembled and replaced, the insertion rod 23 can be pulled down by the pulling rod 12, disengaging the insertion rod 23 from the insertion hole 9 on the surface of the fixed plate 8. After moving the scraper 10 a certain distance, it can be removed from the mixing chamber 3 for replacement. This design allows for quick and convenient installation, use, disassembly, and replacement of the scraper 10, improving the device's practicality.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, a discharge port 4 is provided at the bottom of one end of the mixing chamber 3, and a feed pipe is provided at the upper rear side of the mixing chamber 3. One end of the feed pipe is connected to the input end of the conveying air pump, which can automatically feed materials into the mixing chamber 3. The conveying air pump here is existing technology, such as the XFC-370 single-phase vortex air pump produced by Shanghai Liguan Electromechanical Equipment Co., Ltd., etc., so it will not be described in detail here. Next, a cover plate 14 is provided at the top of the mixing chamber 3, and a connecting block 17 is fixedly welded to both ends of the cover plate 14, and the two support seats 2 are opposite to each other. Each of the two fixed blocks 15 is welded with a fixing block 15, and a cylinder 16 is installed on each fixing block 15. The output end of each cylinder 16 is connected to a connecting block 17. A main stirring shaft 18 is rotatably connected to a cover plate 14. Two driven stirring shafts 19 are rotatably connected to the cover plate 14 on both sides of the main stirring shaft 18. Stirring rods 20 are fixedly installed on the outer side of the main stirring shaft 18 and the two driven stirring shafts 19. Two pulleys 21 are installed on the outer side of the upper end of the main stirring shaft 18, and one pulley 21 is installed on the outer side of the upper end of each of the two driven stirring shafts 19. Then, on the main stirring shaft 18... The two pulleys 21 on the main plate 14 are connected to the pulleys 21 on the two driven stirring shafts 19 by a transmission belt 22. A drive motor is bolted to the upper surface of the cover plate 14 and connected to one end of the main stirring shaft 18 via a coupling. Furthermore, during use, the two cylinders 16 push the cover plate 14 upwards via the connecting block 17, exposing the main stirring shaft 18, driven stirring shaft 19, and stirring rod 20 located on the bottom wall of the cover plate 14, facilitating cleaning. Simultaneously, the plastic particles in the mixing chamber 3 are... When the granules are mixed and stirred, the main stirring shaft 18 can be driven by the drive motor to rotate. Then, the rotating main stirring shaft 18 drives the two pulleys 21 set on the main stirring shaft 18 to rotate. At the same time, through the transmission belt 22 set between the two pulleys 21, the two driven stirring shafts 19 also rotate with the rotation of the main stirring shaft 18. Then, the rotating main stirring shaft 18 and the two driven stirring shafts 19 drive the stirring rod 20 to mix and stir the plastic granules in the mixing chamber 3. Finally, the mixed and stirred plastic granules are discharged through the discharge port 4.

[0028] The working process of this utility model is as follows: First, when the device is in use, the main stirring shaft 18 can be driven to rotate by the drive motor. Then, the rotating main stirring shaft 18 drives the two pulleys 21 set on the main stirring shaft 18 to rotate. At the same time, through the transmission belt 22 set between the two pulleys 21, the two driven stirring shafts 19 also rotate with the rotation of the main stirring shaft 18. Then, the rotating main stirring shaft 18 and the two driven stirring shafts 19 drive the stirring rod 20 to mix and stir the plastic particles in the mixing chamber 3. Finally, the mixed plastic particles are discharged through the discharge port 4. Then, the two cylinders 16 push the cover plate 14 upward through the connecting block 17, thereby exposing the main stirring shaft 18, driven stirring shaft 19 and stirring rod 20 set on the bottom wall of the cover plate 14, which facilitates the cleaning of some materials adhering to the main stirring shaft 18, driven stirring shaft 19 and stirring rod 20.

[0029] Simultaneously, during discharge, the lead screw 6 is driven to rotate by a servo motor. Then, the rotating lead screw 6 drives the moving plate 7 and the scraper 10, which is limited by the moving plate 7, to move within the mixing chamber 3. The moving scraper 10 scrapes off the plastic particles attached to the inner wall of the mixing chamber 3 and pushes the mixed plastic particles within the mixing chamber 3, facilitating their discharge from the discharge port 4 at the bottom of one end of the mixing chamber 3. When the scraper 10 needs to be disassembled and replaced, the insertion rod 23 can be pulled down by the pulling rod 12, thereby disengaging the insertion rod 23 from the insertion hole 9 on the surface of the fixed plate 8. After moving the scraper 10 a certain distance, the scraper 10 can be removed from the mixing chamber 3 for replacement, improving the practicality of the device. The above describes the working principle of this automatic feeding plastic particle mixer.
