[0002] When producing and processing engineering plastics such as polystyrene composites, the materials need to be mixed by stirring to form the corresponding composite materials. During stirring, the raw materials can be processed by a mixer. However, the current mixers use a single stirring method, which has poor stirring efficiency.

[0003] The prior art (Chinese patent publication number CN215139147U, published on December 14, 2021) discloses a high-rigidity, high-gloss polystyrene mixing device, comprising a polystyrene mixing chamber, a mixing motor, a cleaning device, and a bottom movable pad. The mixing motor is fixedly installed at the upper end of the polystyrene mixing chamber. The cleaning device is fixedly installed on the outer side of the upper end of the mixing drive shaft. A cleaning infusion pipe is fixedly installed at the right end of the upper end of the polystyrene mixing chamber, extending inward into the interior of the polystyrene mixing chamber and fixedly connected to the cleaning device. A cleaning nozzle is fixedly installed at the lower end of the cleaning device, with the nozzles evenly distributed at the lower end. A bottom movable pad is installed below the mixing drive shaft. This high-rigidity, high-gloss polystyrene mixing device, with its detachable bottom movable pad used in conjunction with a leak-proof rubber pad, achieves a more thorough cleaning of residual materials, facilitating subsequent work.

[0004] While some current mixers can perform mixing and rinsing functions, materials tend to stick inside the mixer due to their own viscosity. This sticking prevents the materials from being fully mixed, and the sticky materials are also difficult to rinse off, reducing the mixing effect and ease of use of the mixer. Utility Model Content

[0005] The purpose of this invention is to provide a mixer for the production of polystyrene composite materials that can quickly mix materials, thereby solving the problem mentioned in the background art where materials tend to stick together inside the mixer due to their own viscosity, which prevents them from being fully mixed and makes subsequent rinsing of the stuck materials difficult.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixer for the rapid mixing of polystyrene composite materials, comprising a support base, a mixing chamber, and a fixed base. The mixing chamber is disposed on the inner side of the support base, and the fixed base is disposed on the outer side of the mixing chamber. The fixed base and the support base are fixedly connected. A top cover is disposed on the top of the mixing chamber, and a base is detachably connected to the bottom of the mixing chamber. A discharge pipe is installed below the base. The mixing chamber and the fixed base are rotatably connected. A gear ring is fixed on the outer side of the mixing chamber. A movable shaft is rotatably mounted below the top cover, and a stirring rod is fixed on the surface of the movable shaft. The stirring rod is located inside the mixing chamber.

A transmission shaft is fixed above the movable shaft, and a transmission mechanism is disposed on the outer side of the transmission shaft. The transmission mechanism controls the transmission shaft and the gear ring to rotate in opposite directions.

[0007] To further optimize this technical solution, a feed inlet is provided above the top cover to provide a feeding channel for the mixing chamber.

[0008] To further optimize this technical solution, ball bearings are evenly installed on the upper and lower sides of the gear ring to assist the rotation of the gear ring within the fixed seat.

[0009] To further optimize this technical solution, the transmission mechanism includes a transmission gear, an output shaft, a motor, and a transmission belt;

[0010] The transmission gear is positioned on the outside of the gear ring and forms a meshing connection with the gear ring;

[0011] The output shaft is fixed in the middle of the transmission gear, and a rotatable connection is formed between the output shaft and the fixed base;

[0012] The motor is located below the output shaft and connected to the output shaft to control the rotation of the output shaft;

[0013] A drive belt is positioned above the output shaft, and the output shaft is connected to the drive shaft via the drive belt.

[0014] To further optimize this technical solution, the base and the mixing chamber are connected by a thread, and an auxiliary positioning mechanism is provided below the mixing chamber.

[0015] To further optimize this technical solution, the auxiliary positioning mechanism includes an auxiliary groove and a positioning rod;

[0016] An auxiliary tank is located below the mixing chamber;

[0017] The positioning rod and the auxiliary groove form a concave-convex fit structure, and the positioning rod and the base form a threaded connection.

[0018] To further optimize this technical solution, a connecting groove is provided on the left side of the base, and the connecting groove is designed to be vertically continuous. A positioning plate is provided on the left side of the connecting groove, and a control head is fixed on the left side of the positioning plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By attaching the cleaning plate and the inner wall of the mixing chamber, the cleaning plate can clean the material adhering to the inner wall of the mixing chamber, avoid the material from sticking together, and make it better mixed. At the same time, the material sticking together will not affect the subsequent cleaning.

[0021] (2) The materials in the mixing chamber are mixed by the stirring rod, and the rotation of the stirring rod and the cleaning plate can be synchronized, reducing the need for a power source. The rotation of the stirring rod can be synchronized with the rotation of the mixing chamber, further reducing the need for a power source.

[0022] (3) The material can be moved by the rotation of the mixing chamber, and the rotation of the mixing chamber is opposite to the rotation of the mixing rod, thereby improving the mixing and cleaning effect and improving the mixing efficiency.

[0023] (4) The base can be removed by means of the detachable setting between the base and the mixing chamber, so that the inside of the mixing chamber can be exposed, which makes it convenient to clean the device and to deal with the residue on the base.

[0024] (5) The base and the mixing chamber are threaded together. The rotation of the base can be restricted by the connection of the positioning plate and the connecting groove. Then, the connection between the base and the mixing chamber can be automatically released by the rotation of the mixing chamber, which facilitates the disassembly of the base.

The mixing chamber 2 is provided on the inner side of the support base 1, and the fixed base 3 is provided on the outer side of the mixing chamber 2. The fixed base 3 and the support base 1 are fixedly connected.

[0034] Example 1:

[0035] This embodiment provides the following technical solution: a top cover 4 is provided above the mixing chamber 2, and a base 5 is detachably connected to the bottom of the mixing chamber 2. A discharge pipe 6 is installed below the base 5. The mixing chamber 2 and the fixed base 3 are rotatably connected. A gear ring 10 is fixed to the outside of the mixing chamber 2. A movable shaft 7 is rotatably installed below the top cover 4. A stirring rod 8 is fixed to the surface of the movable shaft 7 and is located inside the mixing chamber 2. A cleaning plate 9 is fixed to the surface of the movable shaft 7 and is fitted against the inner wall of the mixing chamber 2. A transmission shaft 14 is fixed above the movable shaft 7, and a transmission mechanism is provided on the outside of the transmission shaft 14. The transmission mechanism controls the transmission shaft 14 and the gear ring 10 to rotate in opposite directions.

[0036] During use, the transmission mechanism controls the rotation of the transmission shaft 14 and the gear ring 10. The transmission shaft 14 drives the movable shaft 7 to rotate, which in turn drives the stirring rod 8 and the cleaning plate 9 to rotate, thus stirring the materials in the stirring chamber 2. At the same time, the cleaning plate 9 cleans the inner wall of the stirring chamber 2 to prevent the materials from sticking together. When the movable shaft 7 rotates, the gear ring 10 will drive the stirring chamber 2 to rotate in the opposite direction, causing the materials to move and improving the uniformity of the stirring.

[0037] Example 2:

[0038] Based on Embodiment 1, a feed inlet 401 is provided on the top of the cover 4 to provide a feeding channel for the mixing chamber 2. Ball bearings are evenly installed on the upper and lower sides of the gear ring 10 to assist the rotation of the gear ring 10 in the fixed seat 3. The transmission mechanism includes a transmission gear 11, an output shaft 12, a motor 13, and a transmission belt 15. The transmission gear 11 is located on the outside of the gear ring 10 and forms a meshing connection with the gear ring 10. The output shaft 12 is fixed in the middle of the transmission gear 11 and forms a rotatable connection with the fixed seat 3. The motor 13 is located below the output shaft 12 and connected to the output shaft 12 to control the rotation of the output shaft 12. The transmission belt 15 is located above the output shaft 12 and the output shaft 12 is connected to the transmission shaft 14 through the transmission belt 15.

[0039] When controlling the rotation of the gear ring 10, the motor 13 can be started, which drives the transmission gear 11 to rotate through the output shaft 12. The transmission gear 11 drives the gear ring 10 to rotate through meshing with it. At the same time, when the output shaft 12 rotates, it will drive the transmission shaft 14 to rotate through the transmission belt 15, so that the transmission shaft 14 and the gear ring 10 rotate in opposite directions, providing stirring power for the device.

[0040] Example 3:

[0041] Based on Embodiment 1, a threaded connection is disclosed between the base 5 and the mixing chamber 2, and an auxiliary positioning mechanism is provided below the mixing chamber 2. The auxiliary positioning mechanism includes an auxiliary groove 16 and a positioning rod 17. The auxiliary groove 16 is located below the mixing chamber 2. The positioning rod 17 and the auxiliary groove 16 form a concave-convex fit structure, and the positioning rod 17 and the base 5 form a threaded connection. A connecting groove 18 is provided on the left side of the base 5, and the connecting groove 18 has a vertical through-structure design. A positioning plate 19 is provided on the left side of the connecting groove 18. A control head 20 is fixed on the left side of the positioning plate 19. The control head 20 and the support base 1 form a left-right sliding structure, and a return spring 21 is provided on the right side of the control head 20.

[0042] When it is necessary to disassemble the base 5, the positioning rod 17 can be rotated first to disconnect the connection between the positioning rod 17 and the auxiliary groove 16, so that the base 5 can rotate relative to the mixing chamber 2. Then, the connecting groove 18 and the positioning plate 19 are aligned, and the control head 20 is pressed to push the positioning plate 19 into the connecting groove 18. Then the mixing chamber 2 can be controlled to rotate. When the mixing chamber 2 rotates, the base 5 is limited, and the threaded connection between the base 5 and the mixing chamber 2 will be released, making it convenient to disassemble the base 5.
