[0002] Plastic products are essential in people's lives, such as tableware, tables and chairs, vehicle accessories, and toys. Traditional plastic coloring methods include direct spraying, which is simple but produces poor color results and is prone to fading. Therefore, plastic color mixing machines were invented. These machines primarily mix plastic raw materials (plastic granules) and color powder in a specific ratio, stirring to coat the surface of the plastic raw materials with color powder, and then conveying the mixture to the barrel of an injection molding machine for heating and mixing. Plastic color mixing machines mainly consist of a plastic raw material feeding device, a color powder feeding device, a mixing device, and a storage device. The plastic raw material feeding device includes a hopper and a feeding valve, which is driven by a motor to open or close. Currently, the shaft of the feeding valve is usually rotatably connected to the feeding hopper, meaning the feeding valve, hopper, and motor are assembled together. When the feeding hopper needs to be disassembled for cleaning, the hopper, valve, and motor must all be removed together, followed by the motor and valve, making installation and disassembly very cumbersome. Summary of the Invention

[0014] This utility model relates to a feeding device for a plastic color matching machine, such as... Figure 1 — Figure 5As shown, the machine includes a body 1, a feeding hopper 2 at the top of the body 1, a storage tank 3 on one side of the body 1, a mixing tank 4 above the storage tank 3, a cover plate 5 on the mixing tank 4, and a feeding inlet 51 in the cover plate 5. The lower opening of the feeding hopper 2 corresponds to the feeding inlet 51, and the feeding inlet 51 communicates with the interior of the mixing tank 4. An electric lifting assembly is located on one side of the body 1 below the feeding hopper 2, and a lifting rod 21 is installed in the electric lifting assembly. A connecting piece 22 is installed on the lifting rod 21 to connect... A long strip-shaped connecting groove 23 is provided in the component 22, and an opening 24 is provided on one side of the connecting groove 23. Two connecting plates 41 are provided on one side of the mixing tank 4. A feed valve 42 is provided between the two connecting plates 41. The feed valve 42 is rotatably connected to the connecting plate 41 via a rotating shaft. The feed valve 42 cooperates with the feed port 51. A connecting seat 43 is provided at the lower part of the feed valve 42. A connecting pin 44 is provided in the connecting seat 43. The connecting pin 44 cooperates with the connecting groove 23 of the connecting component 22.

[0015] Furthermore, the electric lifting assembly includes a feeding motor 25, the output shaft of which is connected to a transmission gear set 26. The transmission gear set 26 is connected to a lead screw 27, and a lifting seat 28 is mounted on the lead screw 27. The lifting seat 28 and the lead screw 27 are engaged by a threaded limit mechanism for lifting. A lifting rod 21 is mounted on the lifting seat 28. The output shaft of the feeding motor 25 drives the transmission gear set 26 to rotate. The transmission gear set 26 can be made up of multiple meshing transmission gears to achieve speed reduction. The lead screw 27 is connected to the last transmission gear. The feeding motor 25 drives the lead screw 27 to rotate via the transmission gear set 26. The lead screw 27 drives the lifting seat 28 to move up and down via the threads on its outer wall. The lifting seat 28 then drives the lifting rod 21 to move up and down.

[0016] Furthermore, a housing 29 is provided outside the lead screw 27 and the lifting seat 28, and the lifting seat 28 makes limiting contact with the inner wall of the housing 29.

[0017] Furthermore, a guide groove 45 is formed on the connecting plate 41, and a guide pin 46 is provided on one side of the feed valve 42, the guide pin 46 cooperating with the guide groove 45. With the guide groove 45 and the guide pin 46, the rotation of the feed valve 42 can be guided and limited.

[0018] This utility model discloses a feeding device for a plastic color matching machine. When the feed inlet 51 is to be closed, the lifting rod 21 of the electric lifting assembly moves upward, the lifting rod 21 drives the connecting piece 22 to move upward, the connecting piece 22 drives the connecting pin 44 to move upward, and the connecting pin 44 drives the connecting seat 43 and the feed valve 42 to rotate upward around the rotating shaft. While the connecting pin 44 rotates upward, it slides along the elongated connecting groove 23, thereby converting the up-and-down movement of the connecting piece 22 into the rotational movement of the connecting pin 44, until the feed inlet 51 is completely closed. When the feed inlet 51 is to be opened, the electric lifting assembly drives the lifting rod 21 and the connecting piece 22 to descend, and the connecting piece 22 drives the connecting pin 44, the connecting seat 43 and the feed valve 42 to rotate downward, thereby opening the feed inlet 51. This solution provides a feeding device for a plastic color matching machine. The up-and-down movement of the electric lifting assembly lifting rod 21 and the connecting piece 22 drives the connecting pin 44, the connecting seat 43, and the feeding valve 42 to rotate and open or close. This allows an opening 24 to be provided on one side of the connecting groove 23 of the connecting piece 22, facilitating the installation and disassembly of the feeding valve 42 and the electric lifting assembly. When changing to different plastic raw materials, it is convenient for people to remove the feeding hopper 2, the cover plate 5, and the feeding valve 42 separately for cleaning, avoiding the mixing of some of the original plastic raw materials with the new plastic raw materials (plastic raw materials of different materials) in corners.
