[0002] The plastic pipe forming device heats plastic raw materials to a molten state, and through the rotation of the screw of the extruder to push, the plastic melt is extruded through the die of the head under a certain pressure to form a plastic pipe blank with a specific cross-sectional shape and size, and then through processes such as cooling and shaping, traction and cutting, etc., to obtain the finished plastic pipe.

[0003] After the pipe is extruded by the extruder, it needs to be quickly cooled and shaped. The conventional method is to use the way of spraying water for shaping. In order to ensure the cooling effect, the pipe needs to be treated with spraying water for a long time, which also leads to a large volume of the entire spraying water system and occupies more space in the processing workshop. In order to increase the output, it is necessary to reduce the spraying distance of water, so it is necessary to improve the existing equipment. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In one embodiment, please refer to Figures 1 - 13 , a plastic pipe forming device, including a base 1, a winding assembly 3 and an extrusion assembly 2 are symmetrically arranged on the sides of the base 1, and further including an air-cooling mechanism 5 and a water-cooling mechanism 6. The extrusion assembly 2 is arranged on the right side of the rear side of the base 1, and the winding assembly 3 is arranged on the left side of the front side of the base 1. Therefore, the plastic pipe 4 produced by the extrusion assembly 2 can be wound by the winding assembly 3 after being cooled by the water-cooling mechanism 6 and the air-cooling mechanism 5;

[0031] The air-cooling mechanism 5 includes support seats 18 arranged on the left and right sides of the upper surface of the base 1. The support seats 18 are arranged with three rods inclined and crossed to reduce wind resistance. A rotatable seat 21 arranged in the left-right direction is rotatably connected to the upper end of the support seat 18. Three support rods 22 are arranged on the outer side of the rotatable seat 21. The support rods 22 extend towards the center direction of the base 1, and the left and right ends of the rotary winding roller 20 are fixedly connected to the ends of the support rods 22 close to the center of the base 1. The rotary winding roller 20 is arranged directly above the base 1 in the left-right direction. A spiral placement groove 39 is arranged on the outer side of the rotary winding roller 20. Anti-slip protrusions are arranged inside the spiral placement groove 39, and the plastic pipe 4 produced by the extrusion assembly 2 is wound around the outside of the rotary winding roller 20 in a spiral state, and the plastic pipe 4 is exactly located inside the spiral placement groove 39. An air flow generating device 19 is arranged at the left end of the base 1. The air flow generating device 19 is arranged at the same height as the rotary winding roller 20. The air flow generating device 19 is a fan that can generate air flow. The air flow generated by the fan flows through the rotary winding roller 20 from left to right, so as to cool the plastic pipe 4 wound around the outside of the rotary winding roller 20 through the air flow, realizing air-cooling treatment;

[0032] The water cooling mechanism 6 includes a heat dissipation pipe 28 provided on the side wall of the rotary winding roller 20. The heat dissipation pipe 28 is arranged horizontally from left to right and is symmetrically arranged with respect to the central circumference of the rotary winding roller 20. A rotating water pipe 25 arranged horizontally from left to right is provided in the middle of the rotating seat 21. A water distribution plate 26 is provided at one end of the rotating water pipe 25 close to the rotary winding roller 20. The water distribution plate 26 is connected to the left and right ends of the heat dissipation pipe 28 through a connecting pipe 27. And a water storage tank 23 is provided in the middle of the upper surface of the base 1. The water storage tank 23 is an open-top container. A pressure pump 24 is provided at the bottom of the right side wall of the water storage tank 23. The pressure pump 24 is a water pump. The water inlet end of the pressure pump 24 communicates with the bottom of the water storage tank 23. The water outlet end of the pressure pump 24 is connected to the lower end of the right water guiding hose 31. The upper end of the right water guiding hose 31 is connected to the right end of the right rotating water pipe 25. The left end of the left rotating water pipe 25 is connected to the lower end of the left water guiding hose 31. The upper end of the left water guiding hose 31 is connected to the water spraying assembly 30. The water spraying assembly 30 is located directly above the rotary winding roller 20. The rotary winding roller 20 is located directly above the water storage tank 23. Therefore, the pressure pump 24 pumps the water in the water storage tank 23 into the right rotating water pipe 25. The water flow in the rotating water pipe 25 enters the heat dissipation pipe 28 through the right water distribution plate 26. The water in the heat dissipation pipe 28 flows from right to left. The water flow flows into the left water distribution plate 26 and the rotating water pipe 25. And the water flow enters the water spraying assembly 30 through the left water guiding hose 31. The flowing water drops from the water spraying assembly 30 to the outside of the rotary winding roller 20. The water body drips into the water storage tank 23 after flowing through the outer wall of the rotary winding roller 20. Thus, the treatment of the entire water cycle is realized. The heat of the plastic pipe 4 can be carried away during the water cycle process, and the water cooling treatment of the plastic pipe 4 is realized.

[0033] In a case of this embodiment, the rotary winding roller 20 is a rotating body structure with a raised middle part. A through hole is provided in the middle of the rotary winding roller 20, and heat dissipation fins 29 are arranged inside the through hole. The heat dissipation fins 29 are arranged parallel to the axis line of the rotary winding roller 20. The heat dissipation fins 29 are arranged in the left-right direction. The airflow passing through the heat dissipation fins 29 can take away the heat on the heat dissipation fins 29, thereby improving the heat dissipation effect of the rotary winding roller 20, enabling the heat of the plastic pipe 4 to be cooled more quickly through the rotary winding roller 20 itself. Moreover, the heat dissipation fins 29 are also in contact with the heat dissipation pipe 28, so that the heat dissipation pipe 28 itself can be better cooled, taking away the heat of the water body inside the heat dissipation pipe 28 to achieve the cooling process, so that the water body can then be cooled by water through the water spraying assembly 30. And because the middle part of the rotary winding roller 20 is in a raised state, looking from left to right, the rotary winding roller 20 is composed of four parts: a cylinder in the left-right direction, a frustum of a cone with an inclined surface to the left, a frustum of a cone with an inclined surface to the right, and a cylinder in the left-right direction. Therefore, after the water flow dripping from the water spraying assembly 30 drips along the rotary winding roller 20, the water flow will flow along the outer wall of the rotary winding roller 20 towards the center direction of the rotary winding roller 20, so that the water flow can finally drip better into the water storage tank 23. And because the airflow moves from left to right, at this time the airflow blows the water flow on the left side of the rotary winding roller 20 towards the center direction of the rotary winding roller 20. However, after the airflow flows to the right side of the rotary winding roller 20, due to the decrease in the diameter of the rotary winding roller 20, the air pressure outside the rotary winding roller 20 decreases at this time, thus forming a vortex. Looking from the official drawing, at this time, a clockwise airflow vortex is formed above the right side of the rotary winding roller 20, and a counterclockwise airflow vortex is formed above the right side of the rotary winding roller 20. This vortex can better make the water flow on the right side of the rotary winding roller 20 flow towards the center direction of the rotary winding roller 20, thereby further ensuring that the water flow will finally drip into the water storage tank 23, avoiding the waste of water body.

[0034] In a case of this embodiment, the heat dissipation fins 29, the heat dissipation pipe 28, and the rotary winding roller 20 are all made of heat-conducting materials, and the airflow direction generated by the airflow generating device 19 is opposite to the water flow direction inside the heat dissipation pipe 28. That is to say, during the process of the airflow flowing from left to right, the airflow can achieve the following cooling process:

[0035] First, the airflow can directly cool the plastic pipe 4 wound outside the rotary winding roller 20;

[0036] Second, the airflow can cool the rotary winding roller 20 through the heat dissipation fins 29, and then the rotary winding roller 20 cools the plastic pipe 4 wound outside;

[0037] Third, the airflow can cool the water droplets dripping from the water spraying component 30 and the water droplets dripping from the rotating winding roller 20, so as to cool the water in the water path and further improve the cooling efficiency of water cooling;

[0038] Fourth, the airflow can cool the heat dissipation pipe 28 through the heat dissipation fins 29, so as to cool the water in the heat dissipation pipe 28. The cooled water can be sprayed out through the water spraying component 30 to cool the plastic pipe 4.

[0039] In one case of this embodiment, the end of the rotating water pipe 25 is rotatably connected to the water guiding hose 31. Therefore, when the rotating water pipe 25 rotates with the rotating seat 21, the water guiding hose 31 can stably maintain the stable flow of the water path with the rotating water pipe 25. A rolling motor 35 is arranged on the support seat 18. The output shaft of the rolling motor 35 is fixedly connected with a first belt pulley 36. The first belt pulley 36 is connected to a second belt pulley 38 through a synchronous belt 37. The second belt pulley 38 is fixedly connected to the rotating seat 21. Therefore, the rolling motor 35 rotates the rotating winding roller 20 through a belt drive method, and connects the rotating seat 21 and the rotating winding roller 20 through a support rod 22. The diameter of the support rod 22 is small, which reduces the wind resistance and enables the airflow to enter the inside of the rotating winding roller 20 more smoothly.

[0040] In one case of this embodiment, the water spraying component 30 includes a water spraying frame 33 fixedly connected to the base 1. A water dividing plate 32 is arranged in the middle of the water spraying frame 33. The water inlet end of the water dividing plate 32 is connected to the water guiding hose 31. A spray head 34 is arranged on the side of the water dividing plate 32 close to the rotating winding roller 20. The water spraying frame 33 is arranged on the left and right sides of the base 1 in a U-shaped structure. A water dividing plate 32 arranged in the left and right directions is arranged at the upper end of the water spraying frame 33. The left end of the water dividing plate 32 is communicated with the upper end of the left water guiding hose 31. Spray heads 34 are arranged on the lower surface of the water dividing plate 32. Water flows into the water dividing plate 32 through the water guiding hose 31. The spray heads 34 spray water downward, and the water droplets fall outside the rotating winding roller 20, thus realizing the water cooling treatment.

[0041] In one case of this embodiment, the extrusion component 2 includes an extrusion bracket 16 fixedly connected to the side of the base 1. A spiral extrusion head 17 is arranged on the extrusion bracket 16. The output end of the spiral extrusion head 17 extrudes the plastic pipe 4. The extrusion bracket 16 is vertically arranged on the right side of the rear side of the base 1. The spiral extrusion head 17 extrudes the plastic pipe 4 forward, and the hot plastic pipe 4 is directly wound around the outside of the rotating winding roller 20.

[0042] In a case of this embodiment, the winding assembly 3 includes a winding bracket 7 vertically arranged on the left side of the front side of the base 1. A roller mounting frame 9 is arranged at the upper end of the winding bracket 7. A sliding beam 11 arranged in the left-right direction is slidably connected to the upper part of the roller mounting frame 9. Vertical support plates 12 are arranged on the left and right sides of the upper surface of the sliding beam 11. A winding rotating shaft 14 arranged in the left-right direction is rotatably connected to the upper ends of the support plates 12. A chuck 15 is slidably connected to one end of the winding rotating shaft 14 close to the roller mounting frame 9. The left and right ends of the chuck 15 are detachably connected to the left and right ends of the winding roller 8. The inside of the chuck 15 is an internal hexagonal structure, and the left and right ends of the winding roller 8 are external hexagons. Therefore, after the winding roller 8 is inserted into the chuck 15, the winding roller 8 can rotate synchronously with the chuck 15. And a spring cooperating with the winding rotating shaft 14 is arranged inside the chuck 15. The spring will push the chuck 15 outward, so that the chuck 15 is pressed against the two ends of the winding roller 8, realizing the fixation treatment of the winding roller 8. A winding motor 13 is arranged on the left support plate 12. The output shaft of the winding motor 13 is fixedly connected to the left end of the left winding rotating shaft 14. Therefore, the winding motor 13 can drive the winding roller 8 to rotate, thus realizing the winding treatment of the plastic pipe 4. An electric telescopic rod 10 is arranged below the roller mounting frame 9. The extending end of the electric telescopic rod 10 is fixedly connected to the sliding beam 11. By pushing the sliding beam 11 to move left and right through the electric telescopic rod 10, the winding roller 8 can move left and right when winding the plastic pipe 4, so that the plastic pipe 4 can be wound more stably on the outside of the winding roller 8.

[0043] During the implementation of this embodiment, raw materials are filled into the internal part of the spiral extrusion head 17 according to the operation method of an ordinary extruder. The spiral extrusion head 17 is started. The spiral extrusion head 17 extrudes the plastic pipe 4. An artificial hand holds the free end of the plastic pipe 4, winds the plastic pipe 4 around the outside of the rotating winding roller 20, and finally winds the plastic pipe 4 around the outside of the winding roller 8. The chucks 15 are separated to both sides, and the winding roller 8 is placed in the middle of the chucks 15. The chucks 15 clamp the winding roller 8. At this time, the preparation treatment of the plastic pipe 4 is completed.

[0044] The air flow generating device 19 is started. The air flow generating device 19 blows out a cooling air flow to the right. The pressure pump 24 is started. The water flows from the water storage tank 23 from right to left through the heat dissipation pipe 28, and the water body finally sprays onto the outside of the rotating winding roller 20 through the nozzle 34. At this time, the plastic pipe 4 generated by the spiral extrusion head 17 is shaped after being completed with air cooling and water cooling. The shaped plastic pipe 4 is wound around the outside of the winding roller 8.

[0045] The present invention is applicable to a plastic pipe forming device. By winding the plastic pipe 4 around the outside of the rotating winding roller 20, the plastic pipe 4 can be quickly cooled down through the double cooling of the water cooling mechanism 6 and the air cooling mechanism 5 in a limited space, so that the volume of the whole forming device is smaller. By designing the rotating winding roller 20 into a structure with a raised middle part, the water flow flowing through the outside of the rotating winding roller 20 can better converge towards the middle and drip into the water storage tank 23, and the unidirectional air flow generated by the air flow generating device 19 can blow the water bodies on both sides towards the middle through the change of the outer diameter of the rotating winding roller 20, so that the water flow can better converge towards the middle, avoiding the waste caused by the splashing of the water body.

[0046] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
