[0019] The overall concept of this utility model is as follows: By activating the feeding component 4 and the two sets of second electric cylinders 44, the feeding box 43 can be rotated. After the feeding box 43 rotates, polyurethane raw material flows into the primary mixing component 2 through the outlet on the feeding box 43, enabling rapid feeding of the two polyurethane raw materials and saving time on step-by-step feeding. Through the primary mixing component 2, after the polyurethane raw material is injected onto the sieve plate 23, it can flow along the grid grooves of the sieve plate 23. Activating the first drive motor 24 drives the mixing rod 25 to rotate, completing the mixing operation of the polyurethane raw material in the mixing hopper 21. This completes the feeding of the polyurethane raw material. After processing, materials with apertures larger than the mesh grooves of the sieve plate 23 remain on the sieve plate 23. By activating the first electric cylinder 27, the push plate 28 can be quickly pushed to the left to push the polyurethane raw materials on the sieve plate 23 into the recycling box 6, thus quickly realizing the material recycling operation. Through the secondary mixing component 5, after the two polyurethane raw materials are mixed by the primary mixing component 2, they are further mixed by the conveying component 4, which ensures that the two polyurethane raw materials flowing into the secondary mixing component 5 are fully mixed. By activating the second drive motor 52, the two polyurethane raw materials can be further mixed, and the initiator can be injected through the liquid inlet pipe 54 to further improve the mixing effect of the polyurethane raw materials.

After the polyurethane raw material is injected into the screen plate 23, it can be discharged along the grid groove of the screen plate 23. By turning on the first drive motor 24, the mixing rod 25 can be driven to rotate to complete the mixing operation of the polyurethane raw material in the mixing hopper 21.
[0021] In some embodiments, more specifically, an extension plate 26 is detachably mounted at one end of the sieve plate 23, a first electric cylinder 27 is detachably mounted on the extension plate 26, a push plate 28 is detachably mounted on the output end of the first electric cylinder 27, and the push plate 28 is located at one end of the sieve plate 23. After the polyurethane raw material feeding operation is completed, the material with a aperture larger than the grid groove of the screen plate 23 stays on the screen plate 23. By activating the first electric cylinder 27, the push plate 28 can be quickly pushed to the left to push the polyurethane raw material on the screen plate 23 into the recycling box 6, which can quickly realize the material recycling operation.
[0022] Next, a more specific structure and construction of the feeding component 4 will be given for further explanation. The feeding component 4 includes a base plate 41, which is detachably mounted on the feeding rack 1. A vertical plate 42 is detachably mounted on the base plate 41. A feeding box 43 is rotatably arranged on one end of the vertical plate 42. A second electric cylinder 44 is detachably mounted on the base plate 41. A bearing 45 is detachably mounted on the edge of the feeding box 43, and the bearing 45 is rotatably connected to the output end of the second electric cylinder 44. Next, the working principle and effect of the feeding component 4 will be further explained. By opening the two sets of second electric cylinders 44 on the left and right, the feeding box 43 can be rotated. After the feeding box 43 rotates, the polyurethane raw material can flow into the primary mixing component 2 through the outlet on the feeding box 43, which can realize the rapid feeding operation of the two polyurethane raw materials and save the time of step feeding.
[0023] In some embodiments, in order to prevent material leakage when the feeding box 43 is in a balanced position, a leakage opening is provided on the feeding box 43, and the leakage opening is located at the upper part of the feeding box 43, while the upright plate 42 is located at the middle part of the feeding box 43.
[0024] Next, a more specific structure and construction of the secondary mixing component 5 will be given for further explanation. The secondary mixing component 5 includes a mixing tank 51, which is located inside the feeding rack 1.

[0027] In summary, by activating the feeding component 4 and the two sets of second electric cylinders 44, the feeding box 43 can be rotated. After the feeding box 43 rotates, polyurethane raw materials flow into the primary mixing component 2 through the openings on the feeding box 43. This enables rapid feeding of the two polyurethane raw materials, saving time spent on step-by-step feeding. Through the primary mixing component 2, after the polyurethane raw materials are injected onto the sieve plate 23, they flow along the grid grooves of the sieve plate 23. Activating the first drive motor 24 drives the mixing rod 25 to rotate, completing the mixing operation of the polyurethane raw materials in the mixing hopper 21. After the polyurethane raw material feeding operation is completed, the aperture is larger than... The material in the mesh groove of the sieve plate 23 remains on the sieve plate 23. By activating the first electric cylinder 27, the push plate 28 can be quickly pushed to the left to push the polyurethane raw material on the sieve plate 23 into the recycling box 6, which can quickly realize the material recycling operation. Through the secondary mixing component 5, after the two polyurethane raw materials are mixed by the primary mixing component 2, they are further mixed by the conveying of the feeding component 4, which can make the two polyurethane raw materials flowing into the secondary mixing component 5 fully mixed. By activating the second drive motor 52, the two polyurethane raw materials can be further mixed, and the initiator can be injected through the liquid inlet pipe 54 to further improve the mixing effect of the polyurethane raw materials.
