Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic granule mixing device. Background Technology

[0002] Plastic granules are simply plastic particles, primarily existing as semi-finished plastic products, facilitating storage, transportation, and processing. Plastic granules possess numerous properties, including mechanical properties, heat resistance, low-temperature resistance, aging resistance, flexural strength, and electrochemical properties. Their applications are diverse, primarily in films, packaging, woven plastic products, injection molding, and pipe and profile products.

[0003] In the current production process of plastic products, various plastic granules are mixed together before processing, thus requiring the use of a mixing device. When using this device, different plastic granules need to be poured into the mixing tank separately according to appropriate proportions. However, existing mixing devices typically lack a batching function, requiring manual batching, which easily leads to inaccurate batching and inconsistent product quality. Utility Model Content

[0004] The purpose of this invention is to provide a plastic granule mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic granule mixing device, comprising a support, a mixing tank fixedly mounted above the support, and a mixing assembly disposed within the mixing tank. The mixing tank is equipped with a dispensing assembly, which includes a U-shaped tube fixedly mounted above the support, a dispensing box, a counterweight, inserts A and B respectively fixedly mounted below the dispensing box and the counterweight, sealing plugs A and B respectively fixedly mounted below inserts A and B, a feed pipe fixedly mounted above the mixing tank, a valve A mounted on the feed pipe, a conveying pipe, and a control assembly. The U-shaped tube is filled with oil. The dispensing box is located in front of the counterweight. Sealing plugs A and B are both inserted into the U-shaped tube and connected to the oil. A convex ring is fixedly mounted at the top of the U-shaped tube. Inserts A and B are located inside the convex ring and connected to it. The two ends of the conveying pipe are connected to the inside of the dispensing box and the feed pipe, respectively.

[0006] Preferably, the control assembly includes a controller fixedly mounted above the mixing tank, a metal plate fixedly mounted above the ingredient box, and a metal sensor fixedly mounted above the counterweight. The metal plate is located on the rear side of the ingredient box, and the detection head of the metal sensor faces forward. Valve A is an electric valve, and both valve A and the metal sensor are connected to the controller via wires.

[0007] Preferably, the stirring assembly includes a rotating shaft fixedly and rotatably disposed inside the stirring tank, a plurality of stirring plates fixedly disposed on the rotating shaft, and a motor fixedly disposed above the stirring tank. The output shaft of the motor is fixedly connected to the rotating shaft, and a plurality of triangular grooves are formed on the stirring plates.

[0008] Preferably, the conveying pipe is an elastic pipe.

[0009] Preferably, the outside of the mixing tank is wrapped with a heating belt.

[0010] Preferably, a discharge pipe is fixedly installed below the mixing tank, and a valve B is installed on the discharge pipe.

[0011] Preferably, a plurality of protrusions are fixedly provided on the left and right sides of the stirring plate, and the protrusions are in contact with the inner sidewall of the stirring tank.

[0012] The beneficial effects of this utility model are as follows: When using this utility model, the oil is poured into the U-shaped tube, and both sealing plugs A and B are inserted into the U-shaped tube to contact and connect with the oil. Inserts A and B are positioned inside the convex ring and in contact with it. The mixing box is located in front of the counterweight. The dispensing port of the external dispensing device is placed above the mixing box. Valve A and the metal sensor are connected to the controller via wires. The controller is also connected to the control components of the external dispensing device via wires. The counterweight is greater than the weight of the mixing box, so the counterweight will be located below the mixing box. The external dispensing device is activated to pour the material into the mixing box. When the weight of the material in the mixing box equals the weight of the counterweight, the mixing box is flush with the top of the counterweight. At this time, the metal sensor detects the metal piece and transmits the signal to the controller. The controller then controls the external dispensing device to stop dispensing and open valve A. At this point, the mixing box... The internal materials enter the mixing tank through the conveying pipe and the feed pipe. After the material conveying is completed, valve A is closed and the external discharge device is opened (it is closed and opened at regular intervals according to the material conveying time required; for example, if the material conveying time is nine minutes, valve A is closed for ten minutes and then reopened). At this time, the counterweight is located below the batching box again, and a new round of feeding can be started. The weight of the material fed into the mixing tank each time will always be consistent, which plays a role in accurate batching. Multiple batching components can be set up to batch multiple materials at the same time. In summary, this utility model has the beneficial effect of accurate batching, which solves the problem that when using a mixing device, different plastic granules need to be poured into the mixing tank in appropriate proportions. Existing mixing devices usually do not have a batching function, and manual batching is used, which easily leads to inaccurate batching and inconsistent product quality. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a plastic granule mixing device, including a support 1, a mixing tank 2 fixedly mounted above the support 1, and a mixing assembly disposed inside the mixing tank 2. The mixing tank 2 is equipped with a dispensing assembly, which includes a U-shaped tube 3 fixedly mounted above the support 1, a dispensing box 4, a counterweight 5, inserts A6 and B7 respectively fixedly mounted below the dispensing box 4 and the counterweight 5, sealing plugs A8 and B9 respectively fixedly mounted below the inserts A6 and B7, and a fixedly mounted... The mixing tank 2 has a feed pipe 10 above it, a valve A11 installed on the feed pipe 10, a conveying pipe 12, and a control component. The U-shaped pipe 3 is filled with oil. The mixing box 4 is located in front of the counterweight 5. The sealing plugs A8 and B9 are inserted into the U-shaped pipe 3 and are in contact with the oil. A convex ring 13 is fixedly installed at the top of the U-shaped pipe 3. The inserts A6 and B7 are located inside the convex ring 13 and are in contact with the convex ring 13. The two ends of the conveying pipe 12 are connected to the inside of the mixing box 4 and the feed pipe 10, respectively. In use, the oil is poured into the U-shaped tube 3, and both sealing plugs A8 and B9 are inserted into the U-shaped tube 3 to contact the oil. Inserts A6 and B7 are positioned inside the convex ring 13 and in contact with it. The mixing box 4 is located in front of the counterweight 5. The dispensing port of the external dispensing device is placed above the mixing box 4. Valve A11 and metal sensor 16 are connected to controller 14 via wires. Controller 14 is also connected to the control unit of the external dispensing device via wires. The counterweight 5 is heavier than the mixing box 4 and will be positioned below it. The external dispensing device is activated to pour material into the mixing box 4. When the weight of the material in the mixing box 4 equals that of the counterweight 5, the top of the mixing box 4 and the counterweight 5 are aligned. At this point, the metal sensor 16 detects the metal piece 15 and transmits the signal to controller 14. Controller 14 then controls the external dispensing device to stop dispensing and open valve A11. At this time, the material inside the mixing box 4 will enter the mixing tank 2 through the conveying pipe 12 and the feeding pipe 10. After the material is conveyed, the valve A11 is closed and the external feeding device is opened (it is closed and opened at regular intervals according to the material conveying time. For example, if the material conveying time is nine minutes, valve A11 will be closed for ten minutes and then reopened). At this time, the counterweight 5 is back below the mixing box 4, and a new round of feeding can be started. The weight of the material fed into the mixing tank 2 each time will always be consistent, which plays a role in accurate feeding. Multiple sets of feeding components can be set to feed multiple materials at the same time. In summary, this utility model has the beneficial effect of accurate feeding. It solves the problem that when using a mixing device, different plastic particles need to be poured into the mixing tank 2 in appropriate proportions. Existing mixing devices usually do not have a feeding function. Using manual feeding can easily lead to inaccurate feeding and result in inconsistent product quality.

[0020] Preferably, the control assembly includes a controller 14 fixedly mounted above the mixing tank 2, a metal plate 15 fixedly mounted above the ingredient box 4, and a metal sensor 16 fixedly mounted above the counterweight 5. The metal plate 15 is located on the rear side of the ingredient box 4, and the detection head of the metal sensor 16 faces forward. The valve A11 is an electric valve, and both the valve A11 and the metal sensor 16 are connected to the controller 14 via wires. Since both the valve A11 and the metal sensor 16 are connected to the controller 14 via wires, it facilitates the control of the opening and closing of each component. (The functions to be implemented by each piece of hardware in this invention are supported by a large number of mature technologies. The essence of this invention lies in the fact that, for specific application scenarios, the above connection and control methods are all existing technologies and do not involve modifications to the internal software of the hardware.)

[0021] Preferably, the stirring assembly includes a rotating shaft 17 fixedly and rotatably disposed inside the stirring tank 2, a plurality of stirring plates 18 fixedly disposed on the rotating shaft 17, and a motor 19 fixedly disposed above the stirring tank 2. The output shaft of the motor 19 is fixedly connected to the rotating shaft 17. The stirring plates 18 are provided with a plurality of triangular grooves 20. Because the stirring plates 18 are provided with a plurality of triangular grooves 20, the space occupied by the stirring plates 18 is reduced. After the stirring plates 18 are grooved, multiple edges are formed, which can thoroughly mix and stir the materials.

[0022] Preferably, the feed pipe 12 is an elastic pipe. Because the feed pipe 12 is an elastic pipe, the elastic pipe will not fall off when the dispensing box 4 moves.

[0023] Preferably, the mixing tank 2 is wrapped with a heating belt 21. Since the mixing tank 2 is wrapped with a heating belt 21, when the material is somewhat damp, the heating belt 21 can be turned on to remove moisture from the material while it is being mixed.

[0024] Preferably, a discharge pipe 22 is fixedly installed below the mixing tank 2, and a valve B23 is installed on the discharge pipe 22. The valve B23 on the discharge pipe 22 facilitates material removal.

[0025] Preferably, a plurality of protrusions 24 are fixedly provided on the left and right sides of the stirring plate 18, and the protrusions 24 are in contact with the inner wall of the stirring tank 2. Since the protrusions 24 are in contact with the inner wall of the stirring tank 2, they play the role of stirring the material at the edge of the tank wall.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
