[0002] High-polymer ASA is a functional polymer powder made primarily of acrylonitrile-styrene-acrylate copolymer. It possesses excellent resistance to ultraviolet radiation, oxidation, and temperature differences. Therefore, high-polymer ASA powder is not prone to aging, discoloration, or cracking during long-term outdoor use. During production, a twin-screw extruder is required to melt-blend various raw materials.

[0003] The existing twin-screw extruders have fixed feeding hoppers. The production of high-polymer ASA requires a large amount of raw material, necessitating manual stirring and unblocking for smooth feeding, which is time-consuming and labor-intensive. Furthermore, the feeding hopper is located at the top, posing a safety hazard to operators who need to climb to operate it. Therefore, an innovative design based on the existing twin-screw extruder is urgently needed to address these issues. Summary of the Invention

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a raw material mixing device for the production of high-polymer ASA powder, including a twin-screw extruder 1, a feeding pipe 2, a corrugated hose 3, a feeding hopper 4, a support plate 5, a servo motor 6, a cam 7, a drag-reducing roller 8, a vertical plate 9, a horizontal plate 10, a positioning plate 11, a support roller 12, a limiting groove 13, a top frame 14, a limiting roller 15, and a spring telescopic rod 16. The feeding pipe 2 is installed on the top of the twin-screw extruder 1, and the corrugated hose 3 is fixed to the top of the feeding pipe 2. The top of the corrugated hose 3 is connected and fixed to the bottom of the feeding hopper 4. The support plate 5 is fixed on the top of the twin-screw extruder 1, and the servo motor 6 is fixed to the front side of the support plate 5. A servo motor 6 is mounted on the output shaft of the servo motor 6. Cam 7, one side of cam 7 is in contact with drag-reducing roller 8, drag-reducing roller 8 is rotatably mounted on one side of vertical plate 9, the top of vertical plate 9 is fixedly connected to the bottom of one end of horizontal plate 10, and a positioning plate 11 is fixed between the other side of vertical plate 9 and the bottom end of horizontal plate 10. A support roller 12 is rotatably mounted on one side of the top of support plate 5, the top of support roller 12 is in contact with the middle of the bottom surface of horizontal plate 10, and a top frame 14 is fixed on the other side of the top of support plate 5. A limiting groove 13 passes through the bottom of top frame 14, the limiting groove 13 is opened on the side of horizontal plate 10, and a limiting roller 15 is rotatably mounted on the inner side of top frame 14. The bottom end of limiting roller 15 is in contact with the top surface of horizontal plate 10, and the other end of horizontal plate 10 is connected and fixed to feeding hopper 4.

[0022] In this example, a spring telescopic rod 16 is fixedly installed on the other side of the support plate 5. The end of the spring telescopic rod 16 is connected and fixed to the middle of the outer wall of the feeding hopper 4. The spring telescopic rod 16 is horizontally symmetrically distributed about the center of the feeding hopper 4. The above structural design enables the horizontal plate 10 and the feeding hopper 4 to stably return to a horizontal position under the elastic force of the spring telescopic rod 16 when the cam 7 squeezes the drag-reducing roller 8.

[0023] The width of the support plate 5 is greater than the width of the horizontal plate 10, and the width of the horizontal plate 10 is greater than the outer diameter of the top of the feeding hopper 4. The above structural design makes the horizontal plate 10 more stable during movement, and the support plate 5 can provide stable support for the horizontal plate 10.

[0024] Both the cam 7 and the drag-reducing roller 8 have mirror surfaces. The cam 7 is distributed at equal intervals in the horizontal direction, and the drag-reducing roller 8 is distributed at equal intervals in the vertical direction. The above structural design makes the resistance small when the cam 7 and the drag-reducing roller 8 are in contact, ensuring the overall stability and smooth operation of the device.

[0025] The support rollers 12 are evenly spaced, and the length of the support rollers 12 is not less than half the width of the horizontal plate 10. The above structural design enables the support rollers 12 to provide stable support for the horizontal plate 10 and ensure the smooth horizontal movement of the horizontal plate 10.

[0026] The inner wall of the limiting groove 13 fits against the bottom of the top frame 14. The side view of the top frame 14 is an inverted "U" shape. The length of the limiting roller 15 installed on the inner side of the top frame 14 is greater than 3 / 4 of the width of the horizontal plate 10. The above structural design enables the top frame 14 to horizontally limit the horizontal plate 10. The horizontal plate 10 can slide stably relative to the bottom of the top frame 14 with the limiting groove 13, and the other end of the horizontal plate 10 is stably squeezed by the limiting roller 15 to ensure that the horizontal plate 10 remains horizontal and to prevent the horizontal plate 10 from tilting due to the weight of the feeding hopper 4 and the material.

[0027] Working principle: During production, the material is poured into the feeding hopper 4, and the servo motor 6 is started. The servo motor 6 drives the cam 7 to rotate in one direction. When the protruding part of the cam 7 contacts the drag-reducing roller 8, it squeezes the drag-reducing roller 8 and the vertical plate 9. Figure 2 The horizontal plate 10 slides horizontally to the left. The horizontal plate 10 slides steadily to the left on the support roller 12. The horizontal plate 10, along with the limiting groove 13, slides relative to the bottom of the top frame 14. The horizontal plate 10 also slides steadily to the left at the bottom of the limiting roller 15. At the same time, the horizontal plate 10, along with the feeding hopper 4, moves horizontally to the left, causing the corrugated hose 3 to slightly deform and bend, and squeezing the spring telescopic rod 16.

[0028] Subsequently, the protruding part of cam 7 separates from the drag-reducing roller 8. Under the elastic force of spring telescopic rod 16, horizontal plate 10 moves horizontally to the right and resets with feeding hopper 4. This process is repeated, and feeding hopper 4 performs small-amplitude high-frequency horizontal vibration, smoothly shaking the material in feeding hopper 4 into feeding pipe 2, realizing unmanned and smooth feeding. This is the working principle of the raw material mixing device for high-colloidal powder ASA production.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
