In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. 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.
[0021] Please see Figures 1-4 This utility model provides an embodiment of a water-cooled feeding device for a double-layer co-extrusion extruder for rubber tubes, including a main body box 1. A receiving base 4 is fixedly connected to one end of the main body box 1. A condensation component is installed inside the main body box 1, and a heat dissipation component is installed inside the receiving base 4. The heat dissipation component and the condensation component are interconnected. A drain valve 6 and a water injection valve 7 are fixedly connected to the surface of the main body box 1. The drain valve 6 is located directly below the water injection valve 7. The condensation component can quickly cool the discharge connecting pipe 20, thereby quickly shaping the tubular product entering it and ensuring the normal use of the subsequent coating. At the same time, the heat dissipation component can dissipate heat from the tubular product and the cooling water, so that it can have a good heat conduction effect when used again.
[0022] In this embodiment, the condensation assembly includes a water tank 15, a water pump 16, a water filling pipe 17, a surrounding cooling pipe 18, a cooling chamber 19, and a discharge connection pipe 20. The discharge connection pipe 20 is installed through the main body box 1, and the cooling chamber 19 is opened inside the main body box 1. The surrounding cooling pipe 18 is sleeved on the surface of the discharge connection pipe 20. One end of the surrounding cooling pipe 18 is fixedly connected to the water filling pipe 17, and the lower end of the water filling pipe 17 is fixedly connected to the water pump 16. The water tank 15 is opened inside the main body box 1, and the water pump 16 is placed inside the water tank 15. The drain valve 6 and the water filling valve 7 are both connected to the water tank 15. By surrounding the cooling pipe 18 on the surface of the discharge connection pipe 20, when the controlled product is placed inside the discharge connection pipe 20, the heat in the product can be introduced into the surrounding cooling pipe 18, and the heat can be carried away by the flowing water. The water pump 16 can provide a power source for the water inside the pipe.
[0023] In this embodiment, the heat dissipation assembly includes an auxiliary roller 2, a fixed frame 3, an exhaust grille 5, a cooling fan 8, a fan mounting slot 9, a fixed plate 10, a heat dissipation chamber 11, a condenser 12, an atomizing nozzle 13, a first connecting pipe 14, a second connecting pipe 21, and a rotary bearing 22. A set of fixed frames 3 is fixedly connected to the upper end of the receiving base 4, and an auxiliary roller 2 is arranged between two opposing fixed frames 3. Rotary bearings 22 are fixedly connected to both ends of the auxiliary roller 2, and the auxiliary roller 2 is rotatably connected to the fixed frame 3 through the rotary bearings 22. On the fixed frame 3, a heat dissipation chamber 11 is provided inside the receiving base 4. A fixed plate 10 is fixedly connected inside the receiving base 4. A condenser 12 is fixedly connected to one end of the fixed plate 10. The condenser 12 is placed inside the heat dissipation chamber 11. An atomizing nozzle 13 is fixedly connected to the input end of the condenser 12. A first connecting pipe 14 is fixedly connected to one end of the atomizing nozzle 13. One end of the first connecting pipe 14 is fixedly connected to the surrounding cooling pipe 18. A second connecting pipe 21 is fixedly connected to the output end of the condenser 12, and one end of the second connecting pipe 21 is placed inside the cooling pipe 18. Inside the water tank 15, a set of fan mounting slots 9 are provided on the upper end of the receiving base 4. A cooling fan 8 is installed inside the receiving base 4 and is placed in the fan mounting slots 9. The fan mounting slots 9 are connected to the heat dissipation chamber 11. A set of air outlet grilles 5 are provided on the surface of the receiving base 4 and are connected to the heat dissipation chamber 11. The water inside the cooling pipe 18 can be introduced into the condenser 12 through the first connecting pipe 14 and atomized by the atomizing nozzle 13 before entering the condenser 12. The atomized water with heat is rapidly cooled inside the condenser 12 and then introduced back into the water tank 15 through the second connecting pipe 21. The cooling fan 8 can draw the heat of the outside air into the heat dissipation chamber 11 and then discharge it from the heat dissipation chamber 11 through the air outlet grilles 5. The product can be conveyed in parallel by the auxiliary roller 2. During the conveying process, the cooling fan 8 draws in air and simultaneously draws the heat on the surface of the product into the heat dissipation chamber 11, thereby providing secondary heat dissipation for the product.
[0024] Cooling water is injected into the water tank 15 through the water injection valve 7. The water pump 16 is turned on to start the cooling water circulation system. The rubber tube enters the discharge connection pipe 20 from the extruder outlet. The cooling water surrounding the cooling pipe 18 quickly absorbs the heat of the rubber tube, causing it to cool down and solidify rapidly. After absorbing heat, the cooling water flows back to the water tank 15 through the heat dissipation component. The water pump 16 continues to draw cooling water from the water tank 15 to maintain circulation. Before entering the condenser 12 through the first connection pipe 14, the cooling water is atomized into fine water droplets by the atomizing nozzle 13. The atomized water droplets increase the contact area with the air, thereby rapidly cooling inside the condenser 12. However, the condensed water returns to the water tank 15 through the second connecting pipe 21. The cooling fan 8 starts, drawing cold air from outside into the cooling chamber 11, while simultaneously expelling the hot air in the cooling chamber 11 through the air outlet grille 5. The auxiliary roller 2 guides the rubber tube for parallel conveying. The cold air drawn in by the cooling fan 8 can also remove the heat from the surface of the rubber tube, achieving secondary heat dissipation. The cooling water circulates between the condensation component and the heat dissipation component, ensuring that the rubber tube remains at a low temperature during the discharge process. Through continuous cooling and heat dissipation, the device can operate stably for a long time without the need for frequent addition of flowing water, greatly saving production costs.
[0025] By using a condensation component, the discharge connection pipe 20 can be rapidly cooled, enabling it to assist in the discharge of the controlled product when connected to the extruder outlet and to rapidly cool it, ensuring the internal pipes remain stable during subsequent secondary coating. The heat dissipation component can provide secondary cooling for the controlled product on the auxiliary roller 2, and simultaneously dissipate heat from the cooling water when air is drawn into the heat dissipation chamber 11, allowing the device to operate continuously. Compared to traditional cooling structures, there is no need to continuously add flowing water, greatly saving production costs.
[0026] This specification describes 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.
