[0002] ABS, or acrylonitrile-butadiene-styrene copolymer, is a thermoplastic. This material combines the properties of acrylonitrile (A), butadiene (B), and styrene (S), thus possessing excellent physical, chemical, and electrical properties.

[0003] The mixer used in ABS production lines is a crucial piece of equipment in the plastics processing industry. It is mainly used to uniformly mix ABS resin granules with other additives to ensure the quality and performance of the final product. In the existing technology, the inner wall of the mixer needs to be manually cleaned after use, which increases the workload and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing mixers, such as the need for manual cleaning of the inner wall after use, which increases the workload and makes them inconvenient to use. This invention proposes a mixer for ABS production lines with an automatic cleaning function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixer for an ABS production line with automatic cleaning function includes a mixing cylinder, with support legs fixed at the four corners of the bottom of the mixing cylinder, and a discharge pipe provided at the bottom of the mixing cylinder, with a flow regulating valve inside the discharge pipe;

[0007] The mixing cylinder has a top plate fixed at its top end, a stirring shaft rotating at its bottom end, and four stirring blades fixed on the surface of the stirring shaft for mixing the raw materials. Two scrapers are provided at the far ends of the four stirring blades, and a set of positioning components is provided inside each of the four stirring blades. The four sets of positioning components are used to drive the two scrapers away from the inner wall of the mixing cylinder.

[0008] The fifth groove is provided with a connecting plate. Two cleaning nozzles for spraying cleaning water are fixedly connected to the surface of the connecting plate. The stirring shaft has a sixth groove. The connecting plate slides in the sixth groove. A fixed connecting pipe is fixedly connected to the top of the connecting plate. The fixed connecting pipe moves upward and penetrates the top plate.

[0009] And a squeezing assembly used in conjunction with four sets of positioning components, the squeezing assembly being used to drive two scrapers to adhere to the inner wall of the mixing cylinder and to drive two cleaning nozzles away from the fifth groove;

[0010] The drive assembly is located inside the top plate and is used to drive four stirring blades for stirring. The drive assembly is also used to drive two scrapers for rotating cleaning.

[0011] In one possible design, each of the positioning components includes a third groove formed within the stirring blade, a first extrusion block sliding within the third groove, a connecting rod fixed to the side end of the first extrusion block, the connecting rod moving outward through the side end of the stirring blade, a scraper fixed to the side end of the connecting rod, a positioning spring fixed to the side end of the first extrusion block, the side end of the positioning spring fixed within the third groove, and the positioning spring sleeved on the surface of the connecting rod.

[0012] In one possible design, the extrusion assembly includes two connecting grooves, both of which are formed inside the stirring shaft. Each of the two connecting grooves is connected to four third grooves. A second extrusion block slides within each of the two connecting grooves. A single vertical rod is fixed within each of the two second extrusion blocks. The vertical rod moves upwards and penetrates into a sixth groove, which is in contact with the bottom end of a connecting plate. A fourth groove is formed inside the stirring shaft, and a connecting plate slides within this fourth groove. The connecting plate is fixed to the surface of the vertical rod, and a lifting spring is fixed to the bottom end of the connecting plate. The bottom end of the lifting spring is fixed within the fourth groove, and the lifting spring is sleeved on the surface of the vertical rod. The two second extrusion blocks are in contact with the four first extrusion blocks.

[0013] In one possible design, the extrusion assembly further includes a first groove formed in the top plate, a slide plate sliding in the first groove, the fixed connecting pipe being rotatably connected to the slide plate, an electric push rod being fixed to the top of the top plate, and the slide plate being fixed to the output end of the electric push rod.

[0014] In one possible design, the drive assembly includes a drive motor fixed in a first groove, a second groove formed in the top plate, a first gear fixed on the surface of the stirring shaft, a second gear rotating in the second groove and meshing with the first gear, and the drive motor connected to the second gear via a coupling.

[0015] In one possible design, the top end of the fixed connecting pipe is rotatably connected to a water delivery pipe, which is connected to the outlet of the water pump.

[0016] In this application, when it is necessary to clean the inner wall of the mixing cylinder, the electric push rod is activated to drive the slide plate downward. The downward movement of the slide plate drives the fixed connecting pipe downward, which in turn drives the connecting plate downward. The connecting plate will drive the cleaning nozzle to leave the fifth groove. The connecting plate will drive the vertical rod downward, which will drive the two second extrusion blocks downward. The two second extrusion blocks will respectively extrude the first extrusion blocks on both sides. The first extrusion blocks on both sides will be extruded and move in opposite directions. The four first extrusion blocks will drive the two scrapers to adhere to the inner wall of the mixing cylinder through the four connecting rods. The water pump will be activated to send water to the two cleaning nozzles for spraying to clean the inner wall of the mixing cylinder. The drive motor will be activated to drive the second gear to rotate. The rotation of the second gear will drive the first gear to rotate. The rotation of the first gear will drive the stirring shaft to rotate. The stirring shaft will drive the scraper to perform a circular motion, and the scraper will scrape and clean the inner wall of the mixing cylinder.

[0017] After cleaning, the electric push rod is activated to reset the slide plate, which in turn resets the fixed connecting pipe and the connecting plate. The elasticity of the lifting spring pushes the connecting plate to reset, which in turn resets the vertical rod. The vertical rod then resets the two second pressing blocks. The first pressing block loses its pressing force, and the scraper is reset by the elasticity of the positioning spring.

[0018] Beneficial Effects: This invention provides a mixer for an ABS production line with an automatic cleaning function. By incorporating a scraper and positioning components, the scraper maintains a distance from the inner wall of the mixing cylinder during mixing, preventing interference with the mixing process. Furthermore, when cleaning is required, the extrusion component drives the scraper to adhere to the inner wall of the mixing cylinder for effective cleaning, thus solving the problem of raw material residue.

[0019] In this invention, a mixer for an ABS production line with automatic cleaning function is provided. By setting a cleaning nozzle and an extrusion assembly, when cleaning is required, the extrusion assembly drives the cleaning nozzle to leave the fifth groove and spray cleaning liquid onto the inner wall of the mixing cylinder. At the same time, the scraper is driven to rotate and clean, which improves the cleaning efficiency and cleaning effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figures 1-4 A mixer includes a mixing cylinder 1. Support legs 2 are welded to the four corners of the bottom of the mixing cylinder 1. A discharge pipe is provided at the bottom of the mixing cylinder 1, and a flow regulating valve is installed inside the discharge pipe to control the discharge volume of the mixed ABS raw material. A top plate 3 is welded to the top of the mixing cylinder 1. A stirring shaft 4 rotates at the bottom of the top plate 3. Four stirring blades 5 are welded to the surface of the stirring shaft 4. Scrapers 6 are provided at the far ends of the four stirring blades 5. The scrapers 6 are used to scrape off the raw material adhering to the inner wall of the mixing cylinder 1 during mixing to prevent raw material residue. Each of the four stirring blades 5 is provided with a set of positioning components. The four sets of positioning components are used to drive two scrapers 6 away from the inner wall of the mixing cylinder 1.

[0027] A fifth groove 25 is formed on the side wall of the mixing cylinder 1. A connecting plate 23 is provided in the fifth groove 25. Two cleaning nozzles 24 are fixedly connected to the surface of the connecting plate 23 for spraying cleaning liquid to clean the inner wall of the mixing cylinder 1. A sixth groove 27 is formed in the stirring shaft 4. The connecting plate 23 slides in the sixth groove 27. A fixed connecting pipe 11 is fixedly connected to the top of the connecting plate 23. The fixed connecting pipe 11 moves upward through the top plate 3 and is connected to an external water pump to provide cleaning liquid to the cleaning nozzles 24.

[0028] In addition, it includes a squeezing assembly that works in conjunction with four positioning assemblies. The squeezing assembly is used to drive two scrapers 6 to adhere to the inner wall of the mixing cylinder 1 when cleaning is required, and to drive two cleaning nozzles 24 out of the fifth groove 25 so that they can spray cleaning liquid onto the inner wall of the mixing cylinder 1.

[0029] It also includes a drive assembly, which is located inside the top plate 3 and is used to drive four stirring blades 5 to stir. At the same time, the drive assembly is also used to drive two scrapers 6 to rotate and clean, so as to improve cleaning efficiency.

[0030] Each positioning assembly includes a third groove 16 formed within the stirring blade 5. A first extrusion block 18 slides within the third groove 16. A connecting rod 15 is welded to the side end of the first extrusion block 18, and the connecting rod 15 extends outward through the side end of the stirring blade 5. A scraper 6 is welded to the side end of the stirring blade 5 and fixed to the connecting rod 15. A positioning spring 17 is welded to the side end of the first extrusion block 18, and the side end of the positioning spring 17 is welded within the third groove 16. The positioning spring 17 is sleeved on the surface of the connecting rod 15. Under the elastic force of the positioning spring 17, the first extrusion block 18 can push the connecting rod 15 and the scraper 6 outward, maintaining a distance from the inner wall of the mixing cylinder 1. This prevents the scraper 6 from rubbing against the inner wall of the mixing cylinder 1 during mixing, reducing wear and tear.

[0031] The extrusion assembly includes two connecting grooves, both of which are located within the stirring shaft 4 and are connected to four third grooves 16. Second extrusion blocks 26 slide within each of the two connecting grooves, and a single vertical rod 22 is welded to each of the two second extrusion blocks 26. The vertical rod 22 moves upwards through a sixth groove 27 and makes extrusive contact with the bottom end of a connecting plate 23. A fourth groove 19 is also located within the stirring shaft 4, and a connecting plate 21 slides within this groove. The connecting plate 21 is welded to the surface of the vertical rod 22. A lifting spring 20 is welded to the bottom end of the connecting plate 21, and its bottom end is welded to the fourth groove 19. The lifting spring 20 is fitted onto the surface of the vertical rod 22. Under the elastic force of the lifting spring 20, the vertical rod 22 can cause the second extrusion blocks 26 to release the extrusion state of the first extrusion block 18. At this time, under the elastic force of the positioning spring 17, the scraper 6 maintains its distance from the inner wall of the mixing cylinder 1. When cleaning is required, the vertical rod 22 is moved downwards, causing the second extrusion block 26 to press against the first extrusion block 18, and the scraper 6 can adhere to the inner wall of the mixing cylinder 1. At the same time, the vertical rod 22 can also move the connecting plate 23 and the cleaning nozzle 24 upwards, causing them to leave the fifth groove 25 for spray cleaning.

[0032] The extrusion assembly also includes a first groove 7 formed within the top plate 3, a slide plate 8 sliding within the first groove 7, and a fixed connecting pipe 11 rotatably connected within the slide plate 8. An electric push rod 10 is welded to the top of the top plate 3, and the slide plate 8 is welded to the output end of the electric push rod 10. By extending and retracting the electric push rod 10, the slide plate 8 and the fixed connecting pipe 11 can be moved up and down, thereby causing the connecting plate 23 and the cleaning nozzle 24 to move up and down.

[0033] This application can be used for mixing in ABS production lines, or in other fields applicable to this application.

[0034] Example 2: Reference Figures 1-4 A mixer with automatic cleaning function for ABS production lines is disclosed. Based on Embodiment 1, this improvement includes a drive assembly comprising a drive motor 9 welded into a first groove 7, a second groove 12 formed in the top plate 3, a first gear 13 welded to the surface of the stirring shaft 4, and a second gear 14 rotatably meshing with the first gear 13 within the second groove 12. The drive motor 9 is connected to the second gear 14 via a coupling. The rotation of the drive motor 9 drives the second gear 14 and the first gear 13 to rotate, thereby driving the stirring shaft 4 and the stirring blades 5 to rotate, thus mixing the ABS raw materials. Simultaneously, when cleaning is required, the drive motor 9 can also drive the scraper 6 to rotate for cleaning, improving cleaning efficiency.

[0035] The top end of the fixed connecting pipe 11 is rotatably connected to a water supply pipe, which is connected to the outlet of the water pump and the inlet of the water pump is connected to an external water source to provide cleaning fluid to the cleaning nozzle 24.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 9 and the electric push rod 10 are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
