Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2As shown in the figure, a TPU raw material pretreatment device according to an embodiment of the present invention includes a housing 1; the top of the housing 1 is connected to an inlet 2, multiple grooves are opened on the inner side of the housing 1, a filter plate 3 is provided on the inner side of the housing 1, the filter plate 3 is slidably connected to the grooves, a first motor 4 is fixedly connected to the side of the housing 1, a first rotating rod 5 is fixedly connected to the output end of the first motor 4, the first rotating rod 5 is rotatably connected to the housing 1, a striking block 6 is fixedly connected to the surface of the first rotating rod 5, a guide plate 7 is fixedly connected to the side of the filter plate 3, a heating tank 8 is fixedly connected to the inside of the housing 1, a hot air blower 9 is fixedly connected to the outside of the housing 1, the air outlet of the hot air blower 9 is connected to the heating tank 8, and the surface of the heating tank 8... The filter plate 3 has an opening, and the guide plate 7 is slidably connected to the opening. A second motor 10 is fixedly connected to the top of the outer casing 1. A second rotating rod 11 is fixedly connected to the output end of the second motor 10. A scraper 12 and a spiral blade 13 are fixedly connected to the surface of the second rotating rod 11. A sealing assembly is provided inside the opening. During operation, the first rotating rod 5 is driven to rotate by the first motor 4. The first rotating rod 5 drives the impact block 6 to rotate the roller 18. When the roller 18 rotates to the top, it can impact the bottom of the filter plate 3, pushing the filter plate 3 to move upward. When the roller 18 moves to the bottom, the spring 17 pulls the filter plate 3 to reset, causing the filter plate 3 to shake up and down. When the first rotating rod 5 rotates, it causes the guide plate 7 to slide up and down within the inlet. Simultaneously, the guide plate 7 moves the limiting plate 20 within the chute, allowing the raw material to be poured into the outer casing 1 through the feed inlet 2. The raw material falls onto the filter plate 3 through the feed inlet 2 and is separated by the diverting plate 19. The continuous rotation of the first rotating rod 5 causes the filter plate 3 to shake up and down, agitating the raw material on its surface for filtration. The shaking of the filter plate 3 allows the raw material on its surface to pass through the guide plate 7 and enter the heating tank 8. The hot air blower 9 heats the heating tank 8. The second rotating rod 11 rotates via the second motor 10, which in turn rotates the spiral blades 13 and scraper 12. There are two scraper 12s. 2. The raw material at the bottom of the heating tank 8 is stirred. When there is a lot of raw material, the spiral blades 13 drive the raw material to move upward. By setting up a chute, a first rotating rod 5, a ram 6 and a guide plate 7, the rotation of the first motor 4 can drive the ram 6 to rotate, which pushes the guide plate 7 to shake up and down, screening and filtering the raw material on the guide plate 7 to prevent the raw material from accumulating. By setting up a hot air blower 9, a second motor 10, a second rotating rod 11, a scraper 12 and a spiral blade 13, the second motor 10 can drive the scraper 12 to rotate in the heating tank 8, stirring the raw material at the bottom of the heating tank 8. The spiral blades 13 drive the raw material to move upward, which can effectively prevent the raw material from accumulating and sticking at the bottom of the heating tank 8.

[0024] like Figure 2As shown, an opening is provided on the side of the outer casing 1, and a collection box 14 is slidably connected to the inner side of the outer casing 1. A baffle 15 is fixedly connected to the bottom of the filter plate 3. During operation, impurities in the raw material fall through the filter plate 3 and enter the collection box 14. The baffle 15 blocks the falling impurities. By setting the opening, the collection box 14 and the baffle 15, the collection box 14 can catch the filtered impurities at the bottom of the filter plate 3. A handle is fixedly connected to the side of the collection box 14. The handle can be pulled through the opening to pull the collection box 14 out of the outer casing 1 for replacement and cleaning of the impurities inside. The baffle 15 can block the impurities passing through the filter plate 3, making it easier for them to enter the collection box 14.

[0025] like Figure 3 As shown, a fixing block 16 is fixedly connected to the inner side of the outer casing 1, and a spring 17 is fixedly connected to the top of the fixing block 16. The top of the spring 17 is fixedly connected to the filter plate 3. During operation, the filter plate 3 moves upward, and the spring 17 pulls the filter plate 3 downward. By setting the fixing block 16 and the spring 17, the spring 17 can pull the filter plate 3 to move downward automatically, so that the filter plate 3 can contact the impact block 6 more quickly, increasing the vibration frequency of the filter plate 3.

[0026] like Figures 3 to 4 As shown, a roller 18 is rotatably connected to the inner side of the impact block 6. The surface of the roller 18 is in contact with the filter plate 3. During operation, the impact block 6 drives the roller 18 to rotate, and the surface of the roller 18 contacts the bottom surface of the filter plate 3, pushing the filter plate 3 to shake. By setting the roller 18 so that its surface can contact the bottom of the filter plate 3, the friction and noise between the impact block 6 and the filter plate 3 are reduced.

[0027] like Figure 4 As shown, a flow divider 19 is fixedly connected to the top of the filter plate 3. There are several flow dividers 19. During operation, the raw material is separated by the flow dividers 19 and then enters the guide plate 7. By setting the flow dividers 19, which have a rhomboid structure and are several in number, it can prevent the raw material on the surface of the filter plate 3 from flowing too fast on the surface of the filter plate 3, thus increasing the filtration time on the filter plate 3.

[0028] like Figure 5 As shown, the sealing assembly includes a limiting plate 20, and a sliding groove is provided at the bottom of the opening. The limiting plate 20 is slidably connected to the sliding groove. During operation, the guide plate 7 drives the limiting plate 20 to move up and down. The limiting plate 20 moves up and down in the sliding groove. By setting the limiting plate 20 and the sliding groove, the limiting plate 20 can move up and down inside the sliding groove, preventing the raw material from falling out of the opening through the bottom of the guide plate 7, and thus sealing the opening.

[0029] Working principle: The first motor 4 drives the first rotating rod 5 to rotate, which in turn drives the impact block 6 to rotate the roller 18. When the roller 18 rotates to the top, it impacts the bottom of the filter plate 3, pushing the filter plate 3 upward. When the roller 18 moves to the bottom, the spring 17 pulls the filter plate 3 back to its original position, causing the filter plate 3 to swing up and down. As the filter plate 3 moves, it drives the guide plate 7 to slide up and down within the opening. The guide plate 7 simultaneously drives the limiting plate 20 to move within the chute, allowing the raw material to be poured into the outer shell 1 through the feed inlet 2. The raw material falls onto the filter plate 3 through the feed inlet 2 and is separated by the diverting plate 19. The continuous rotation of the first rotating rod 5 causes the filter plate 3 to swing up and down, agitating the raw material on the surface of the filter plate 3 for filtration. The filtered impurities pass through the filter plate 3 into the collection box 14. Pulling the handle on the outside of the collection box 14 to the left moves it out of the outer shell 1. The material on the surface of the filter plate 3 is shaken and enters the heating tank 8 through the guide plate 7. The hot air blower 9 blows air into the heating tank 8 for heating. The second motor 10 drives the second rotating rod 11 to rotate. The second rotating rod 11 drives the spiral blade 13 and scraper 12 to rotate. There are two scrapers 12. The scrapers 12 stir the material at the bottom of the heating tank 8. When there is a lot of material, the spiral blade 13 drives the material to move upward to prevent the material from accumulating and causing insufficient heating. The top of the heating tank 8 is equipped with a pressure relief valve to release the pressure inside the heating tank 8 and prevent the internal air pressure of the heating tank 8 from being too high. After heating is completed, the bottom of the heating tank 8 is connected to the discharge valve. The material in the heating tank 8 is discharged through the discharge valve at the bottom of the outer shell 1.
