Description
Technical Field
[0001] This utility model relates to the technical field of closed rubber mixing mills, and more specifically, it relates to a dust-proof rubber mixing mill. Background Technology
[0002] A closed-type rubber mixing mill, also known as an internal mixer or kneader, is mainly used for the plasticizing and mixing of rubber. An internal mixer is a machine equipped with a pair of rotors of specific shapes that rotate relative to each other, intermittently plasticizing and mixing polymer materials under adjustable temperature and pressure in a closed environment. It mainly consists of a mixing chamber, rotors, rotor sealing devices, feeding and pressing devices, unloading devices, transmission devices, and a base.
[0003] When raw materials are fed into the internal mixer, dust is easily generated because the particles in the raw materials are small. This dust not only pollutes the working environment, but may also have adverse effects on the health of the workers. Utility Model Content

[0023] Reference Figures 1 to 3 This utility model provides a technical solution: a dust-proof rubber internal mixer, including a mixer body 1, a column 2 fixedly connected to the mixer body 1, a material hopper 3 fixedly connected to the column 2, and a feeding port 4 opened on the side wall of the material hopper 3. Figure 2 Raw materials can be fed into the feeding hopper 3 through the feeding port 4. A motor 5 is installed on the feeding hopper 3, and the output shaft of the motor 5 is connected to a vertical shaft 6 via a coupling. A spiral blade 7 is fixedly connected to the vertical shaft 6. Figure 2 The output shaft of motor 5 drives the vertical shaft 6 to rotate, which in turn drives the spiral blades 7 on it to rotate. The spiral blades 7 then agitate the raw materials in the material bucket 3, stirring them and dispersing dust. A fan 8 is installed on the material bucket 3, and a dust suction pipe 9 is connected to the air inlet of the fan 8. The end of the dust suction pipe 9 furthest from the fan 8 is connected to the interior of the material bucket 3. Figure 2 The dust suction pipe 9 can extract the dust generated at the feeding port 4 when the raw materials are fed into the feeding hopper 3, and also extract the dust generated when the spiral blades 7 agitate the raw materials. A filter screen 10 is fixedly connected to the end of the dust suction pipe 9 furthest from the fan 8. Figure 2 The filter screen 10 can filter the dust drawn by the dust suction pipe 9, thereby preventing the dust from drifting outside the material bucket 3 and protecting the working environment and personnel health. The bottom of the material bucket 3 is connected to the feed pipe 11. The end of the feed pipe 11 away from the material bucket 3 is connected to the feed port of the internal mixer body 1. After the raw materials are mixed, they enter the internal mixer body 1 through the feed pipe 11. A valve 12 is installed on the feed pipe 11 to control the opening and closing of the feed pipe 11.

A driven bevel gear 15 is fixedly connected to one end of the horizontal shaft 14, and a driving bevel gear 16 is meshed with the driven bevel gear 15. The driving bevel gear 16 is fixedly connected to the vertical shaft 6, and a brush plate 17 is fixedly connected to the other end of the horizontal shaft 14. The bristles of the brush plate 17 rub against the filter screen 10.
[0025] like Figure 2 and Figure 3 The vertical shaft 6 can drive the active bevel gear 16 to rotate. The active bevel gear 16 drives the horizontal shaft 14 to rotate through the driven bevel gear 15. The horizontal shaft 14 drives the brush plate 17 to rotate.

[0027] like Figure 2 and Figure 3 When there is no raw material inside the material bucket 3, turn off the blower 8 and clean the filter screen 10 through the brush plate 17. At this time, the impurities cleaned off the filter screen 10 will fall into the collection box 19. The cleaned impurities can be collected and the collection box 19 can be pulled out for cleaning.
[0028] Specifically, a support plate 20 is fixedly connected to the side wall of the material hopper 3, and the support plate 20 abuts against the lower end of the collection box 19, such as... Figure 2 The tray 20 can help support the collection box 19.

[0030] Specifically, a glass window 22 is fixedly connected to the side wall of the material barrel 3 to facilitate observation of the interior of the material barrel 3.
[0031] Working principle: The output shaft of motor 5 drives the vertical shaft 6 to rotate, and the vertical shaft 6 drives the spiral blades 7 on it to rotate. The spiral blades 7 can stir the raw materials in the material bucket 3, stir the raw materials, and throw out the dust in the raw materials. The dust generated at the feeding port 4 when the raw materials are put into the material bucket 3 can be extracted through the dust suction pipe 9, and the dust generated when the spiral blades 7 stir the raw materials can also be extracted. The filter screen 10 can filter the dust extracted by the dust suction pipe 9, thereby preventing the dust from drifting outside the material bucket 3 and protecting the working environment and personnel health.
