Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, specifically a high-efficiency feeding device for an internal mixer. Background Technology

[0002] An internal mixer is a piece of equipment used for mixing plastics or rubber. It primarily operates within a closed, cylindrical container, where the rotation of an impeller equipped with blades shears the material. The main component of an internal mixer is the mixing chamber, also known as the plasticizing chamber. The upper part houses the feeding device, and the lower part is the discharge port, with a bolt at both the top and bottom. When the upper and lower bolts are closed, a closed plasticizing chamber is formed.

[0003] Extensive searches revealed that the Chinese Utility Model Patent Publication No. CN221733674U discloses a high-efficiency feeding device for an internal mixer, including an auxiliary material tank. Multiple fixing rods are fixedly connected to the upper inner side of the auxiliary material tank. A support plate is fixedly connected to all the fixing rods. An electric motor is fixedly installed at the upper end of the support plate. The output shaft of the electric motor passes through the support plate and is connected to the support plate via a bearing. A connecting sleeve is bolted to the end of the output shaft. A connecting seat is fixedly connected to the bottom of the connecting sleeve, and two stirring rods are fixedly connected to the bottom of the connecting seat.

[0004] While the above scheme has many advantages, it also has the following disadvantages: By setting up a stirring rod to stir the material, the material can be dispersed. However, the stirring range of the stirring rod is limited, and there will be dead zones in the stirring. This will affect the material dispersion effect and cause material to accumulate in the dead zones, which will affect the filtration effect of the screen. This reduces the practicality and working efficiency of the high-efficiency feeding device of the internal mixer. Summary of the Invention

[0021] 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.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a high-efficiency feeding device for a mixer, including a device body 1. An agitation chamber 10 is provided on the inner wall of the device body 1. The vertical cross-section of the agitation chamber 10 is a circular cavity. The top and bottom walls of the agitation chamber 10 are provided with openings 16. A screen 2 is fixedly connected to the bottom opening 16. The screen 2 has an arc-shaped structure, and its center coincides with the center of the circular cavity. Rotating rings 3 are rotatably connected to the inner walls on both sides of the agitation chamber 10. A pusher plate 4 distributed in a circular array is fixedly connected between the two rotating rings 3. The outer wall of the pusher plate 4 is in contact with the inner wall of the agitation chamber 10 and the top wall of the screen 2. An agitation mechanism is rotatably connected to the center of the agitation chamber 10.

[0023] The material is fed into the cavity of the mixing chamber 10 through the top opening 16, and the agitation mechanism is used to break up the clumps of material so that the screen 2 can filter it. The filtered material enters the feed inlet of the internal mixer through the bottom opening 16.

[0024] In this process, by rotating the rotating ring 3, the rotating ring 3 drives the pusher plate 4 to move around the inner wall of the stirring chamber 10. The pusher plate 4 scrapes off the attached material on the inner wall of the stirring chamber 10, thus improving the cleaning efficiency of the device body 1. At the same time, the pusher plate 4 pushes the material on the screen 2 to move above the stirring mechanism, so that the material can pass through the stirring range of the stirring mechanism again and be dispersed a second or multiple times, thus improving the material dispersion efficiency and effect.

[0025] like Figure 3 and Figure 4 As shown, the agitation mechanism includes two shafts 5 that are rotatably connected to each other. The two shafts 5 are respectively rotatably connected to the inner walls on both sides of the agitation chamber 10. Agitation rods 6 arranged in a circular array are fixedly connected to the outer side of the shafts 5.

[0026] By rotating shaft 5, the material is stirred by stirring rod 6.

[0027] like Figure 2 and Figure 4 As shown, the device body 1 has two mounting slots 11. An internal gear ring 7, a first gear 8, and a second gear 9 are rotatably connected to the inner wall of the mounting slot 11. A connecting plate is fixedly connected between the internal gear ring 7 and the nearest rotating ring 3. The two sides of the first gear 8 are respectively meshed with the inner wall of the internal gear ring 7 and one side of the second gear 9. The shaft center of one side of the second gear 9 is fixedly connected to the end of the shaft rod 5. The two mounting slots 11 are located on both sides of the stirring chamber 10. An annular groove and a shaft hole are provided between the mounting slot 11 and the stirring chamber 10. The connecting plate is rotatably connected in the cavity of the annular groove. The end of the shaft rod 5 is set in the cavity of the shaft hole. The outer diameter of the second gear 9 is smaller than the outer diameter of the first gear 8.

[0028] By rotating the second gear 9, the second gear 9 drives the shaft 5 to rotate. At the same time, the second gear 9 drives the internal gear ring 7 to rotate through the first gear 8, and the internal gear ring 7 drives the rotating ring 3 to rotate through the connecting plate.

[0029] By utilizing the fact that the outer diameter of the second gear 9 is smaller than that of the first gear 8, the rotational speed of the ring 3 is reduced while the rotational speed of the shaft 5 remains constant, thereby improving the stability of the linkage of its various structures.

[0030] like Figure 2 and Figure 4 As shown, the first gears 8 in the cavities of the two mounting slots 11 are arranged symmetrically to each other, and the two first gears 8 are located on both sides of the second gear 9 respectively;

[0031] The two first gears 8 are arranged opposite each other, which causes the two shafts 5 to rotate relative to each other, thus improving the stirring efficiency and effect of the stirring mechanism.

[0032] like Figure 3 and Figure 4As shown, an arc plate 12 is fixedly connected to the inner wall of the stirring chamber 10. The outer wall of the arc plate 12 is in contact with the side of the pusher plate 4 near the stirring mechanism, and the arc plate 12 is located on one side of the stirring mechanism. The center of the arc plate 12 coincides with the center of the stirring chamber 10.

[0033] By rotating the rotating ring 3, the material is pushed by the pusher plate 4 to the cavity between the outer wall of the arc plate 12 and the stirring chamber 10, so that the material can be moved to the top of the stirring mechanism and thus fall into the stirring range of the stirring mechanism for mixing.

[0034] like Figure 1 - Figure 4 As shown, a servo motor 15 is installed on one side of the device body 1. The movable end of the servo motor 15 is fixedly connected to the shaft center on one side of the second gear 9. The servo motor 15 is electrically connected to the power supply.

[0035] The second gear 9 is driven to rotate by the servo motor 15.

[0036] like Figure 1 As shown, a hopper 13 is installed at the bottom of the device body 1, and a feeding scale 14 is provided at the material inlet at the bottom of the hopper 13.

[0037] The specific related structures of the feeding scale 14 and the feeding hopper 13, as well as the connection methods and usage methods of the related structures, are all existing technologies. For a detailed description, please refer to the corresponding structures and components in the publication number CN221733674U, "A High-Efficiency Feeding Device for a Mixer". This application will not elaborate further.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
