Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to a raw material mixing device for PVC sheet processing. Background Technology

[0002] In the production process of PVC (polyvinyl chloride) sheets, the mixing of raw materials is one of the key steps.

[0003] Existing raw material mixing devices rely solely on a stirring shaft to agitate the raw materials, resulting in poor mixing performance and the creation of dead zones. Furthermore, existing devices fail to fully utilize high-speed airflow to fluidize the plastic masterbatch during the mixing process, thus limiting the mixing speed and effectiveness.

[0004] Therefore, we propose a raw material mixing device for PVC sheet processing to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a raw material mixing device for PVC sheet processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for PVC sheet processing, comprising a tank, a stirring shaft, and a differential rod. The outer wall of the tank is provided with a support assembly, and the top opening of the tank is provided with a cover. The stirring shaft is rotatably mounted on the cover via a drive assembly, and the differential rod is rotatably mounted on the stirring shaft via a differential assembly. The drive assembly and the differential assembly are in a gear-tooth meshing relationship, and an air passage is provided on the differential rod.

[0007] Preferably, the drive assembly consists of a base, a motor, and a gear ring. The base is disposed on the upper surface of the cover, the motor is disposed on the base, and the upper end of the stirring shaft protrudes from the upper surface of the cover.

[0008] Preferably, the gear ring is located at the top of the stirring shaft, and the gear ring is meshed with the gear at the output end of the motor.

[0009] Preferably, the differential assembly consists of a cross plate, a gear shaft, and a half-gear shaft. The cross plate is mounted on the base of the drive assembly, the gear shaft is rotatably mounted on the cross plate, the lower end of the gear shaft meshes with the gear ring of the drive assembly, and the differential lever protrudes from the upper end of the stirring shaft and is rotatably mounted on the cross plate.

[0010] Preferably, the half-tooth shaft is located at one end of the differential lever protruding cross plate, and one half of the half-tooth shaft has a gear structure, and the half-tooth structure of the half-tooth shaft is in a gear-tooth meshing state with the upper end of the gear shaft.

[0011] Preferably, the upper end of the tank is provided with vent holes at equal intervals.

[0012] Preferably, the cover has a feed inlet and the bottom of the tank has a discharge outlet, and both the feed inlet and the discharge outlet are equipped with valve structures.

[0013] Preferably, the support assembly consists of legs and a base ring, the base ring being located at the lower end of the outer wall of the tank, and the top ends of each of the legs being located on the lower surface of the base ring and distributed in a ring array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During use, the raw material mixing device for PVC sheet processing of this utility model can introduce various plastic masterbatch granules for PVC sheet processing into the tank through the inlet, and then close the inlet and outlet.

[0016] Then, an external power source is connected to enable the motor to operate. Through the meshing of the gear teeth, the motor drives the gear ring to rotate, which in turn causes the stirring shaft to rotate on the cover. This stirring shaft mixes various plastic masterbatches inside the tank. At the same time, the air passage at the top of the differential rod is rotatably connected to the air supply pipe of an external air pump structure, thereby introducing high-speed airflow into the tank. The airflow fluidizes the plastic masterbatches, causing the plastic masterbatches particles to suspend, reducing friction between particles, increasing particle flowability, and thus accelerating the mixing of plastic masterbatches in conjunction with the rotation of the stirring shaft.

[0017] Furthermore, during the rotation of the gear ring, the meshing action between the gear ring and the lower end of the gear shaft drives the gear shaft to rotate. The meshing action between the gear shaft and the half-gear shaft drives the differential rod to rotate. The rotation of the differential rod also ensures that the high-speed airflow can be more evenly distributed to all parts of the tank, avoiding local over-stirring or uneven mixing that may be caused by direct airflow impact. Through the distribution of the teeth on the half-gear shaft, the rotational speed of the differential rod relative to the stirring shaft can be reduced. It can create different stirring speed zones, which helps to form more complex flow patterns and further improve the uniformity of mixing. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] like Figures 1-5 As shown, the present invention proposes a raw material mixing device for PVC board processing, including a tank 6, a stirring shaft 7 and a differential rod 9. The outer wall of the tank 6 is provided with a support assembly, and the top opening of the tank 6 is provided with a cover 4. The stirring shaft 7 is rotatably mounted on the cover 4 through a drive assembly, and the differential rod 9 is rotatably mounted on the stirring shaft 7 through a differential assembly. The drive assembly and the differential assembly are in a gear meshing relationship, and an air passage 16 is provided on the differential rod 9.

[0028] Based on Example 1:

[0029] During use, the raw material mixing device for PVC sheet processing of this utility model can introduce various plastic masterbatch granules for PVC sheet processing into the tank 6, and at this time the inlet 3 and outlet 8 are closed.

[0030] Then, an external power source is connected to make the motor 14 work. Through the meshing of the gear teeth, the motor 14 drives the gear ring 15 to rotate, thereby causing the stirring shaft 7 to rotate on the cover 4. The stirring shaft 7 stirs and mixes various plastic masterbatches inside the tank 6. At the same time, the air passage 16 at the top of the differential rod 9 is rotatably connected to the air supply pipe of the external air pump structure, thereby introducing high-speed airflow into the tank 6 through the air passage 16. The airflow fluidizes the plastic masterbatches, causing the plastic masterbatches particles to suspend, reducing the friction between particles, increasing the fluidity of the particles, and thus accelerating the mixing of plastic masterbatches in conjunction with the rotation of the stirring shaft 7.

[0031] Furthermore, during the rotation of the gear ring 15, the meshing action between the gear ring 15 and the lower end of the gear shaft 12 drives the gear shaft 12 to rotate. The meshing action between the gear shaft 12 and the half gear shaft 13 drives the differential lever 9 to rotate. The rotation of the differential lever 9 also ensures that the high-speed airflow can be more evenly distributed to all parts of the tank 6, avoiding local over-stirring or uneven mixing that may be caused by direct airflow impact. Through the distribution of the teeth on the half gear shaft 13, the rotational speed of the differential lever 9 relative to the stirring shaft 7 can be reduced. It can create different stirring speed zones, which helps to form more complex flow patterns and further improve the uniformity of mixing.

[0036] The differential assembly consists of a horizontal plate 11, a gear shaft 12, and a half-gear shaft 13. The horizontal plate 11 is mounted on the base 5 of the drive assembly.

Half of the gear structure of the half-tooth shaft 13 is in a gear tooth meshing state with the upper end of the gear shaft 12. During the rotation of the gear ring 15, the gear shaft 12 is driven to rotate through the meshing action of the gear ring 15 and the lower end of the gear shaft 12. Through the meshing action of the gear shaft 12 and the half-tooth shaft 13, the differential lever 9 is driven to rotate.

[0038] Ventilation holes 10 are provided at equal intervals at the upper end of the tank body 6. Through the design of the ventilation holes 10, the airflow entering the tank body 6 is discharged from the tank body 6 through the ventilation holes 10.
