Description

Technical Field

[0001] This utility model relates to the technical field of plastic running track production equipment, specifically a material mixing device for plastic running track production. Background Technology

[0002] Plastic running tracks are made from polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. They are increasingly favored due to their good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. During the manufacturing process, the uniformity of the mixing of the plastic running track materials directly determines the quality of the track. Uneven mixing will result in uneven color and unbalanced functionality.

[0003] According to a public notice (Announcement No.: CN221249439U) regarding a material mixing device for the production of plastic running tracks, the aforementioned application describes a device where the movement of a drive motor and lead screw, in conjunction with the use of a vertical rod, drives the slip ring to move up and down. The slip ring then drives the heating plate to move up and down. During the operation of the heater, the heat-conducting ring is heated by a heat-conducting wire, and the heat-conducting ring then heats the heating plate. This allows the heating plate to heat the material evenly and thoroughly, facilitating material mixing and improving mixing efficiency.

[0004] However, in actual use, the above-mentioned equipment cannot effectively mix the plastic track granules. When a large number of granules are placed inside the equipment, it is very likely to cause the slip ring to jam, making it impossible for the heat-conducting ring to move up and down effectively, thus failing to effectively heat and mix the material, which seriously affects the efficiency of production. In view of this, we propose a material mixing device for plastic track production. Utility Model Content

[0017] like Figures 1-5As shown, this utility model provides a technical solution: a material mixing device for the production of plastic running tracks, including a fixed base plate 1, a support plate 11 fixedly connected to the upper surface of the fixed base plate 1, a control console 12 fixedly connected to the upper surface of the fixed base plate 1, and a mixing mechanism 2 provided on the upper surface of the support plate 11. The mixing mechanism 2 includes: a mixing drum 21, a feeding port 22, a rotary motor 23, a sun gear 24, a planetary gear 25, a gear rail 26, a fixed shaft 27, a mixing rod 28, a mounting groove 29, an electric heating rod 210, and a fan 211.

[0018] In one embodiment of this utility model, the outer wall of the mixing drum 21 is fixedly connected to the upper surface of the support plate 11, and the support plate 11 can provide sufficient support force to the mixing drum 21. A feeding port 22 is fixedly connected to the upper surface of the mixing drum 21, and a movable door is hinged to the input end of the feeding port 22. The operator can feed materials into the feeding port 22 by pulling the movable door. A rotary motor 23 is fixedly connected to one end of the mixing drum 21 near the control console 12, and a sun gear 24 is fixedly connected to the output end of the rotary motor 23. Planet gears 25 mesh on the outer surface of the sun gear 24. The fixed end of the gear 26 is fixedly connected to the inner wall of the mixing drum 21. The toothed ends of the gear 26 mesh with the outer surface of the planetary gear 25. The end of the sun gear 24 away from the rotary motor 23 is fixedly connected to a fixed shaft 27. The output end of the rotary motor 23 drives the sun gear 24 to rotate. Furthermore, the sun gear 24 drives the planetary gear 25 to rotate around the gear 26 while maintaining its revolution. This further causes the fixed shaft 27 to rotate. The end of the fixed shaft 27 away from the rotary motor 23 has a mounting groove 29. The end of the mounting groove 29 is fixedly connected to an electric motor. A heating rod 210 and a mounting groove 29 are formed inside the fixed shaft 27. The heating rod 210 can heat the interior of the mixing drum 21. Multiple sets of stirring rods 28 arranged in a circumferential array are fixedly connected to the outer surface of the fixed shaft 27. The stirring rods 28 are hollow and have heat dissipation holes on their outer surfaces. The hollow stirring rods 28 dissipate the heat emitted by the heating rod 210, allowing them to penetrate deep into the plastic granules. While stirring, heating is also carried out. A fan 211 is fixedly connected to the end of the stirring drum 21 away from the rotary motor 23. The fan 211 can blow the heated heat into the interior of the stirring drum 21. The interior of the stirring rod 28 is connected to the mounting groove 29. A protective plate is abutted at the end of the sun gear 24 away from the rotary motor 23. The protective plate is circular in shape. The outer wall of the protective plate is rotatably connected to the inner wall of the stirring drum 21. The protective plate can protect the planetary gear system and prevent dust and fine particles generated by stirring from affecting the meshing between the gears.

[0019] In addition, an auxiliary mechanism 3 is provided inside the stirring drum 21. The auxiliary mechanism 3 includes a connecting shaft 31. One end of the connecting shaft 31 is fixedly connected to the end of the planetary gear 25 away from the rotary motor 23. One end of a spiral spring 32 is fixedly connected to the outer surface of the connecting shaft 31. The other end of the spiral spring 32 is fixedly connected to the inner wall of the connecting drum 33. A scraper 34 is fixedly connected to the outer wall of the connecting drum 33. The end of the scraper 34 away from the connecting shaft 31 abuts against the inner wall of the stirring drum 21. A circular through groove matching the size of the connecting shaft 31 is opened on the outer surface of the protective plate, and a circular cover plate is fixedly connected to the end of the connecting drum 33. By setting the spiral spring 32 and the connecting drum 33, the inner wall of the stirring drum 21 can be scraped when working with the scraper 34. When facing more stubborn impurities, the spiral spring 32 will coil and store force to prevent damage to the mechanism of the equipment due to hard contact.

[0020] In this embodiment of the present invention, a collection box 4 is fixedly connected to the upper surface of the fixed base plate 1, and a drawer 41 is slidably connected to the side wall of the collection box 4. A discharge port is fixedly connected to the lower surface of the mixing drum 21. The plastic granules after being fully mixed can be discharged through the discharge port. The material discharged through the discharge port can fall into the inside of the collection box 4. At this time, the operator can pull the drawer 41 to extract the mixed material. The discharge port is set above the collection box 4. The top surface of the support plate 11 is set as an arc surface that matches the outer surface of the mixing drum 21. The top surface of the support plate 11 with the arc surface can fully fit with the outer wall of the mixing drum 21 and can give the mixing drum 21 sufficient support. The electric heating rod 210 is provided with an electric heating wire inside. The electric heating wire inside the electric heating rod 210 can fully heat the inside of the mixing drum 21.

[0021] In this invention, during use, material is fed into the mixing drum 21 through the feeding port 22, and the rotary motor 23 is started to drive the sun gear 24 to rotate. The sun gear 24 drives the planetary gears 25 that mesh with it to move. Since the planetary gears 25 mesh with the gear rails 26 fixed on the inner wall at the same time, the planetary gears 25 generate their own rotation while revolving around the sun gear 24. The fixed shaft 27 connected to the sun gear 24 drives the hollow stirring rods 28 distributed in an outer circumferential array to rotate for stirring. At the same time, the electric motor in the mounting groove 29 at the end of the fixed shaft 27 is used for stirring. The heating rod 210 generates heat when energized, and the heat is conducted to the interior of the hollow stirring rod 28 through the mounting groove 29, and then evenly distributed to the material through the heat dissipation holes on the rod wall. In addition, the planetary gear 25 drives the spiral spring 32 and the connecting cylinder 33 through the connecting shaft 31, so that the scraper 34 on the connecting cylinder 33 rotates tightly against the inner wall of the stirring cylinder 21 to scrape off the adhering material. After the stirring is completed, the material falls into the collection box 4 drawer 41 below through the discharge port at the bottom. The control console 12 is responsible for controlling the entire stirring, heating and scraping process.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
