For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Please see Figures 1-4 This utility model provides an embodiment of a residual material collection device for a double-layer co-extrusion extruder for rubber hoses, including a receiving block 1. A storage tank 5 is provided at the lower end of the receiving block 1, and a snap-fit ​​block 15 is fixedly connected to the lower end of the receiving block 1. The receiving block 1 is snapped onto the storage tank 5 by the snap-fit ​​block 15.

The power component and the snap-fit ​​component are used in conjunction and are connected to each other. The snap-fit ​​component is used to connect to an external double-layer co-extrusion extruder. At the same time, the power component can be used to provide air or water power to the internal pipes of the extruder, thereby quickly cleaning them and ensuring that the internal residual material is completely removed.

[0024] In this embodiment, the power assembly includes a water inlet 9, a fixing block 10, an air intake grille 11, a fan 12, an air intake slot 13, a double-way ball valve 16, a servo motor 17, a ball valve chamber 18, an adjusting slot 19, an air intake channel 20, an air outlet channel 21, and an adjusting rod 22. A ball valve chamber 18 is fixedly connected inside the receiving block 1. An adjusting slot 19 is provided inside the ball valve chamber 18. A double-way ball valve 16 is rotatably connected inside the ball valve chamber 18 and is placed within the adjusting slot 19. An air outlet channel 21 and an air intake channel 20 are provided on the surface of the double-way ball valve 16. The air intake channel 20 and the air outlet channel 21 are perpendicularly arranged and interconnected. An adjusting rod 22 is fixedly connected to the surface of the double-way ball valve 16. The adjusting rod 22 and the air outlet channel 21 are on the same horizontal line. A servo motor 17 is fixedly connected to the surface of the ball valve chamber 18. 7. One end of the adjusting rod 22 is fixedly connected to the output end of the servo motor 17. A water inlet 9 is fixedly connected to the upper end of the ball valve chamber 18. A fixing block 10 is fixedly connected to the surface of the ball valve chamber 18. A fixing block 10 is fixedly connected to the fixing block 10, and the output end of the fixing block 10 is connected to the adjusting groove 19. An air inlet groove 13 is opened in the receiving block 1. An air inlet grille 11 is provided at one end of the receiving block 1. The air inlet grille 11 is connected to the air inlet groove 13. The fan 12 is placed in the air inlet groove 13. The servo motor 17 can drive the adjusting rod 22 to rotate. At the same time, the rotation can drive the double-pass ball valve 16 to rotate synchronously. At this time, the opening of the air inlet groove 20 can switch between the fixing block 10 and the water inlet 9, so as to provide wind or water to the water inlet pipe 8. At this time, the water inlet 9 needs to be connected to an external water supply source.

[0025] In this embodiment, the snap-fit ​​assembly includes a discharge pipe 2, a discharge port connector 3, a first sealing rubber gasket 4, a second sealing rubber gasket 6, a feed port connector 7, a water inlet pipe 8, and a residual material feed trough 14. One end of the receiving block 1 is fixedly connected to the discharge pipe 2, and the other end of the discharge pipe 2 is fixedly connected to the discharge port connector 3. The first sealing rubber gasket 4 is fixedly connected to the inner wall of the discharge port connector 3. A residual material feed trough 14 is provided inside the receiving block 1. One end of the discharge pipe 2 is placed in the residual material feed trough 14, which is connected to the storage tank 5. One end of the receiving block 1 is fixedly connected to the water inlet pipe 8, and the other end of the water inlet pipe 8 is fixedly connected to the ball valve chamber 18. The water inlet pipe 8 is connected to the regulating tank 19. The end of the water inlet pipe 8 away from the ball valve chamber 18 is fixedly connected to the feed port connector 7. The inner wall of the feed port connector 7 is fixedly connected to the second sealing rubber gasket 6. The device is connected to the feed port of the extruder through the feed port connector 7 and to the discharge port through the discharge port connector 3. At this time, the first sealing rubber gasket 4 and the second sealing rubber gasket 6 can ensure the airtightness of the entire passage. When the feed port connector 7 outputs air or water, it can be guided into the extruder and carry out the residual material. The residual material carried out by the air can be directly reused, while the water can be used to remove the residual material that is difficult to remove, ensuring internal cleanliness.

[0026] The receiving block 1 is snapped onto the storage tank 5 via the snap-fit ​​block 15, ensuring a tight connection. The device is then connected to the inlet and outlet of the double-layer co-extrusion extruder via the inlet connector 7 and outlet connector 3 in the snap-fit ​​assembly. The second sealing rubber gasket 6 in the inlet connector 7 and the first sealing rubber gasket 4 in the outlet connector 3 ensure a tight seal at the connection point, preventing air or water leakage. The blower 12 is started, drawing in air through the air intake grille 11. The air passes through the air intake slot 13 and enters the ball valve chamber 18. The servo motor 17 is started, driving the adjusting rod 22 to rotate. Simultaneously, the rotation of the adjusting rod 22 causes the double-way ball valve 16 to rotate within the adjusting slot 19. By controlling the rotation angle of the servo motor 17, the valve can be adjusted... The position of the double-way ball valve 16 is such that its air inlet groove 20 is aligned with the fixed block 10 or the water inlet 9. If air cleaning is required, the adjusting rod 22 aligns the air inlet groove 20 of the double-way ball valve 16 with the fixed block 10. Air enters the water inlet pipe 8 through the air inlet groove 20, and then enters the extruder through the feed port connector 7. If water cleaning is required, the adjusting rod 22 aligns the air inlet groove 20 of the double-way ball valve 16 with the water inlet 9. Water enters the adjusting groove 19 through the water inlet 9, then enters the water inlet pipe 8 through the air inlet groove 20, and finally enters the extruder through the feed port connector 7. The air can quickly carry out the residual material in the pipe. This residual material enters the residual material feed trough 14 through the discharge pipe 2, and finally falls into the storage tank 5. Since the residual material carried out by the air does not contain moisture, it can be directly reused. The water is used to clean the residual material that is difficult to remove by the air, ensuring that the inside of the pipe is thoroughly cleaned. The excess material carried out by the hydraulic system also enters the excess material feed trough 14 through the discharge pipe 2, and finally falls into the storage tank 5.

[0027] The power component can provide either wind or water flushing to the inlet pipe 8, and can switch between the two. This allows for the secondary removal of residual material that is difficult to remove by wind using water. The residual material removed by wind alone is not rich in moisture and can be directly reused. At the same time, the snap-fit ​​component can better fix the two connectors to the double-layer co-extrusion extruder, realize the interconnection inside the pipe, and improve its airtightness.

[0028] This specification describes the embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
