Description

Technical Field

[0001] This utility model relates to the field of PVC plastic granule mixing technology, and in particular to a high-efficiency mixing device for PVC plastic granule production. Background Technology

[0002] The mixing unit in PVC plastic granule production is mainly used to uniformly mix polyvinyl chloride resin with other additives (such as stabilizers, fillers, colorants, etc.) to form a mixture suitable for extrusion, injection molding, and other processes. The mixing unit achieves uniform mixing and dispersion of raw materials through mechanical stirring, ensuring the stability of each component in subsequent processing. For example, a twin-screw extruder can directly use the mixed powder for hot extrusion molding, simplifying the production process. Hot mixing process: At high temperature, twin-screw stirring homogenizes the material into a multiphase homogenate state, while simultaneously completing pre-plasticization treatment (such as lubricant melting) to improve fluidity. Cold mixing stage: At low temperature, wood powder (such as poplar powder, bamboo powder) is mixed with PVC resin to ensure granule uniformity.

[0003] An existing high-efficiency mixing device for PVC plastic granule production is inconvenient for workers to collect the mixed material after the equipment has finished mixing, which affects the overall processing efficiency of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency mixing device for the production of PVC plastic granules.

[0005] This utility model is achieved by the following technical solution: a high-efficiency mixing device for PVC plastic granule production, including a mixing tank, a control cabinet fixedly connected to the front of the mixing tank, a sealing cover plate threadedly connected to the top of the mixing tank, a fixing support ring fixedly connected to the top of the sealing cover plate, a drive motor inserted inside the fixing support ring, a transmission shaft fixedly connected to the output end of the drive motor, and a mixing roller fixedly connected to the surface of the transmission shaft.

[0006] A sealing baffle is inserted into the bottom of the mixing tank. A bearing support rod is fixedly connected to the bottom of the mixing tank. A fixed horizontal plate is fixedly connected to the surface of the bearing support rod. A collection box is slidably connected to the top of the fixed horizontal plate. A rotating column is fixedly connected to the bottom of the fixed horizontal plate. A limit baffle is hinged to the surface of the rotating column. A fixing frame is fixedly connected to the rear end of the fixed horizontal plate. A limit spring is fixedly connected to the front of the fixing frame.

[0007] The above technical solution, with the mixing roller located at the top of the sealing baffle, allows the raw materials to be fully tumbled and kneaded in the closed cavity, shortening the mixing cycle and improving uniformity. The control cabinet is integrated at the bottom of the sealing cover, which can precisely control the motor speed to adapt to different formulation process requirements.

[0008] As a further improvement to the above solution, the bottom of the drive motor contacts the top surface of the sealing cover, the control cabinet is located at the bottom of the sealing cover, and the drive shaft is rotatably connected inside the mixing tank.

[0009] As a further improvement to the above solution, the mixing roller is rotatably connected inside the mixing tank, the drive shaft is located at the top of the sealing baffle, and the mixing roller is located at the top of the sealing baffle.

[0010] Through the above technical solution, the top of the mixing tank forms a sealed space with the fixed support ring through a threaded sealing cover plate. The drive motor is inserted into the fixed support ring, and the transmission shaft connected to its output end drives the mixing roller to rotate at high speed.

[0011] As a further improvement to the above solution, the number of the supporting rods is set to several, and the several supporting rods are symmetrically distributed around the mixing tank, with the collection box located at the bottom of the sealing baffle.

[0012] Through the above technical solution, several load-bearing supports symmetrically distributed around the mixing tank, together with the fixed cross plate, form a multi-point support system, which significantly enhances the overall stability of the equipment.

[0013] As a further improvement to the above scheme, the number of the rotating column and the limiting baffle is set to two, and the two rotating columns and the limiting baffle are symmetrically distributed on the left and right sides with the fixed horizontal plate as the center.

[0014] As a further improvement to the above solution, the front of the limiting spring contacts the rear surface of the collection box, and the number of the limiting springs is set to two, with the two limiting springs symmetrically distributed on the left and right sides with the fixing frame as the center.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows the mixed material to be conveyed to the collection box by sliding the sealing baffle out from the inside of the mixing tank. When the limiting baffle is rotated and moved away from the front of the collection box, the limiting spring on the front of the fixing frame extends and retracts to slide and squeeze the collection box on the fixing plate, making it convenient for workers to take out the mixed material.

[0017] This invention features two symmetrically distributed rotating columns with hinged limit baffles on their surfaces, forming a linkage mechanism with limit springs on the fixed frame. When the collection box is pulled out, the limit springs are compressed and store energy, pushing the collection box to automatically return to its original position. The limit baffles restrict the maximum travel of the collection box, preventing derailment and ensuring both operational safety and rapid positioning. Attached Figure Description

[0027] A sealing baffle 8 is inserted into the bottom of the mixing tank 1. A supporting rod 9 is fixedly connected to the bottom of the mixing tank 1. A fixed horizontal plate 10 is fixedly connected to the surface of the supporting rod 9. A collection box 11 is slidably connected to the top of the fixed horizontal plate 10. A rotating column 12 is fixedly connected to the bottom of the fixed horizontal plate 10. A limit baffle 13 is hinged to the surface of the rotating column 12. A fixed frame 14 is fixedly connected to the rear end of the fixed horizontal plate 10. A limit spring 15 is fixedly connected to the front of the fixed frame 14. When the sealing baffle 8 is pulled out from the inside of the mixing tank 1, the mixed material can be conveyed to the inside of the collection box 11. When the limit baffle 13 is rotated and moved away from the front of the collection box 11, the extension and retraction of the limit spring 15 on the front of the fixed frame 14 will slide and squeeze the collection box 11 on the fixed horizontal plate 10, making it convenient for the staff to take out the mixed material.

[0028] The design of the mixing roller 7 located on top of the sealing baffle 8 allows the raw materials to be fully tumbled and kneaded in the closed cavity, shortening the mixing cycle and improving uniformity. The control cabinet 2 is integrated at the bottom of the sealing cover 3, which can precisely control the motor speed to adapt to different formula process requirements.

[0029] The bottom of the drive motor 5 contacts the top surface of the sealing cover 3, the control cabinet 2 is located at the bottom of the sealing cover 3, and the drive shaft 6 is rotatably connected inside the mixing tank 1.

[0030] The mixing roller 7 is rotatably connected inside the mixing tank 1, and the drive shaft 6 is located on top of the sealing baffle 8.

[0031] The top of the mixing tank 1 is connected to the sealing cover plate 3 by a threaded connection and the fixed support ring 4 to form a closed space. The drive motor 5 is inserted into the fixed support ring 4, and the transmission shaft 6 connected to its output end drives the mixing roller 7 to rotate at high speed.

[0032] The number of support rods 9 is set to several, and the several support rods 9 are symmetrically distributed around the mixing tank 1. The collection box 11 is located at the bottom of the sealing baffle 8.

[0033] Several load-bearing support rods 9 are symmetrically distributed around the mixing tank 1, and together with the fixed cross plate 10, they form a multi-point support system, which significantly enhances the overall stability of the equipment.

[0034] The number of rotating columns 12 and limiting baffles 13 is set to two. The two rotating columns 12 and limiting baffles 13 are symmetrically distributed on the left and right with the fixed horizontal plate 10 as the center. The limiting baffles 13 are hinged to the surfaces of the two symmetrically distributed rotating columns 12, forming a linkage mechanism with the limiting springs 15 on the fixed frame 14. When the collection box 11 is pulled out, the limiting springs 15 are compressed and stored, pushing the collection box 11 to return to its original position automatically. The limiting baffles 13 limit the maximum stroke of the collection box 11 to prevent derailment, thus ensuring operational safety and achieving rapid positioning.

[0035] The front of the limiting spring 15 contacts the rear surface of the collection box 11. The number of limiting springs 15 is set to two, and the two limiting springs 15 are symmetrically distributed on the left and right sides with the fixing frame 14 as the center.

[0036] The implementation principle of the high-efficiency mixing device for PVC plastic granule production in this embodiment is as follows: When the sealing baffle 8 is pulled out from the inside of the mixing tank 1, the mixed material can be transported to the inside of the collection box 11. When the limiting baffle 13 is rotated and moved away from the front of the collection box 11, the limiting spring 15 on the front of the fixed frame 14 is extended and retracted to slide and extrude the collection box 11 on the fixed horizontal plate 10, which makes it convenient for the staff to take out the mixed material. By setting two left and right symmetrically distributed rotating columns 12 with the limiting baffle 13 hinged on their surfaces, a linkage mechanism is formed with the limiting spring 15 on the fixed frame 14. When the collection box 11 is pulled out, the limiting spring 15 is compressed and stored, pushing the collection box 11 to automatically return to its position. By setting the limiting baffle 13, the maximum stroke of the collection box 11 is limited to prevent derailment, which ensures both operational safety and rapid positioning.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
