Description

Technical Field

[0001] The invention belongs to the technical field of plastic pipe production equipment, and in particular relates to water conservancy irrigation plastic pipe production equipment. Background Art

[0002] As an important component of building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene (PPR) hot water pipes. Plastic pipes are widely used in the field of water conservancy and irrigation. Due to long-term exposure to the ground, plastic pipes are usually subject to wear and tear, which will cause leakage in the pipeline over a long period of time. In addition, plastic pipes themselves are brittle and easily damaged. In order to solve this problem, the existing technology usually wraps a wire layer on the outside of the plastic pipe, but the manual wrapping method is inefficient and cannot effectively connect the wire layer to the plastic pipe. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a water conservancy irrigation plastic pipe production device that can automatically wrap a wire layer on the outside of the plastic pipe to improve the production efficiency of the plastic pipe.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] The present invention relates to a water conservancy irrigation plastic pipe production device, comprising an extruder, a die head arranged at the outlet of the extruder, a support tube for the plastic pipe being axially arranged at the outlet of the extruder, a traction assembly for the plastic pipe being arranged at one end away from the extruder, and a wire rope winding assembly being arranged between the traction assembly and the extruder; the wire rope winding assembly comprising a telescopic device, a support seat, a rotating disk, a rotation drive assembly, a support plate, a connecting rod, a radial slider, and a radial guide rail, the rotating disk being rotatably matched with the support seat, the center of the rotating disk being provided with a central through hole for the plastic pipe to pass through, the rotating disk being driven to rotate by the rotation drive assembly, the support plate being rotatably arranged at the center of the rotating disk, the outer circle of the support plate being connected to a radial slider via a connecting rod, the radial slider being slidably matched with the radial guide rail; the slider being provided with a through hole for the wire rope to pass through, the radial guide rail being provided with an open groove corresponding to the through hole, the radial guide rail and the telescopic device being fixed to the surface of the rotating disk, the output shaft of the telescopic device being eccentrically connected to the support plate, and the support plate being capable of driving the radial slider to move via the connecting rod.

[0006] The beneficial effects of the present invention are:

[0007] The present invention relates to a water conservancy irrigation plastic pipe production device. One end of the plastic pipe is extruded by an extruder, and the other end is pulled by a traction component. Through the axial action of the traction force, the plastic pipe can be ensured to maintain a certain rigidity during the molding process, so that the cord winding component can better wind the cord on the surface of the plastic pipe, with good consistency, and relatively high winding accuracy and quality.

[0008] In the production equipment of the present invention, when the rotating disk rotates, the radial slider is driven to rotate, so that multiple groups of ropes can be wound on the outside of the plastic pipe. The winding density is high and it can be applied to the winding of multiple different ropes in the same process, which greatly improves work efficiency.

[0009] In the production equipment of the present invention, the radial slider can be controlled by setting a telescopic device, so that the radial position of the radial slider on the rotating disk is changed. When it is located at the outermost end, the rope is tighter. Therefore, by controlling the radial position of the radial slider, the pre-tightening degree of the rope wrapped around the surface of the plastic pipe can be controlled, and it can adapt to different winding standards.

[0010] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figures 1 to 7 As shown, the present invention provides a water conservancy irrigation plastic pipe production equipment, including an extruder 1 and a die head 2 arranged at the outlet of the extruder 1. The extruder 1 and the die head 2 both adopt existing technologies. The extruder 1 is provided with a quantitative device, which can be normally used to discharge plastic pipes. After discharge, the material is discharged from the central outlet of the die head 2.

[0021] Specifically, a support tube 3 for the plastic pipe is axially arranged at the outlet of the extruder 1. The diameter of the support tube 3 is equivalent to the inner diameter of the plastic pipe. A traction assembly 4 for the plastic pipe is arranged at the end away from the extruder 1. The plastic pipe is pulled by the traction assembly 4 to ensure that the plastic pipe is discharged at a normal speed. A wire rope winding assembly 5 is arranged between the traction assembly 4 and the extruder 1; the wire rope 22 is wound on the outside of the plastic pipe by the wire rope winding assembly 5.

[0022] The wire rope winding assembly 5 includes a telescopic device 6, a support base 7, a rotating disk 8, a rotating drive assembly, a support plate 9, a connecting rod 10, a radial slider 11, and a radial guide rail 12. One end of the telescopic device 6 is fixed to the mounting structure on the rotating disk 8, and the support base 7 can be fixed to the frame 29 of the device. The rotating disk 8 and the support base 7 rotate in conjunction with each other to ensure that the rotating disk 8 can rotate around its own center but is axially limited to prevent the rotating disk 8 from escaping from the support base 7 or causing displacement in other directions. A central through hole 13 is opened in the center of the rotating disk 8 for the plastic pipe to pass through, and the rotating disk 8 is driven to rotate by the rotating drive assembly.

[0023] Furthermore, the support plate 9 is rotatably arranged at the center of the rotating disk 8. The support plate 9 can rotate around the axial direction of the plastic pipe. The outer circle of the support plate 9 is connected to the radial slider 11 through the connecting rod 10. The two ends of the connecting rod 10 are hinged to the support plate 9 and the radial slider 11 respectively. The radial slider 11 slides with the radial guide rail 12. The guide rail is arranged along the radial direction of the rotating disk 8. There are three groups of guide rails on the rotating disk 8. The three groups of guide rails are evenly distributed along the circumference of the rotating disk 8; a through hole 14 is provided on the slider for the rope 22 to pass through. The diameter of the through hole 14 is equivalent to the diameter of the rope 22. An open slot 15 corresponding to the through hole 14 is provided. One end of the rope 22 is connected to the reel 23, and the other end passes through the through hole 14 and the open slot 15 and is wound around the outside of the plastic pipe. The radial guide rail 12 and the telescopic device 6 are fixed to the surface of the rotating disk 8. The output shaft of the telescopic device 6 is eccentrically connected to the support plate 9. When the telescopic device 6 is extended or shortened, it can drive the support plate 9 to rotate. The support plate 9 can drive the radial slider 11 to move through the connecting rod 10, and can realize the synchronous movement of each radial slider 11, which can reduce the control equipment while making the winding of the three groups of ropes 22 more uniform.

[0024] In this embodiment, the rotation drive assembly includes a rotating ring 16, a ring gear 17, a gear, and a first motor. The rotating ring 16 is simultaneously rotatably coupled to the support base 7. The rotating ring 16 and the ring gear 17 are coaxially arranged. The ring gear 17 is fixed to the outside of the rotating ring 16 and meshes with the gear. The gear is connected to the output shaft of the first motor. The first motor is fixed to the frame 29. Rotation of the first motor drives the gear via the output shaft, thereby facilitating the control of the rotation of the rotating disk 8.

[0025] In this embodiment, a protective tube 18 is fixed to the inner side of the through hole 14. The axial direction of the protective tube 18 is parallel to the length direction of the plastic pipe. The rope 22 passes through the protective tube 18. The protective tube 18 can be made of rubber material to reduce the friction between the rope 22 and the inner wall of the through hole 14 or the inner wall of the opening groove 15, thereby protecting the rope 22. The protective tube 18 also passes through the opening groove 15 to provide more complete protection.

[0026] In this embodiment, a guide seat 19 is provided between the traction assembly 4 and the cord winding assembly 5. A boss 20 is provided at the upper end of the guide seat 19. A guide hole 21 is formed in the center of the boss 20 for the passage of the plastic pipe. This guide hole 21 can be used to guide the plastic pipe that has just been wound, so that the cord 22 can be more stably wound around the outside of the plastic pipe. The cord 22 of the present invention is connected to a reel 23, which is coaxially connected to the output shaft of a second motor 24. The second motor 24 is fixed to a bracket 25, and the rotation of the second motor 24 can actively release the cord 22.

[0027] In this embodiment, the traction assembly 4 includes a driving wheel 26, a driven wheel 27, and a third motor 28. The axes of the driving wheel 26 and the driven wheel 27 are perpendicular to the axis of the plastic pipe. The driving wheel 26 and the driven wheel 27 are separated to form a gap for conveying the plastic pipe. The driving wheel 26 is coaxially connected to the output shaft of the third motor 28, and the driven wheel 27 is rotatably connected to the frame 29. The plastic pipe is conveyed by the clamping action between the driving wheel 26 and the driven wheel 27, avoiding the central arrangement position of the plastic pipe, making the layout of the entire invention device more reasonable, and the automatic control of the third motor 28 can also facilitate the control of the output speed of the plastic pipe.

[0028] In this embodiment, the extruder 1 includes a shell 30, a feed pipe 31 connected to one side of the shell 30, and a spiral conveying shaft 32 rotatably arranged in the feed pipe 31. One end of the feed pipe 31 forms a discharge port corresponding to the die head 2. A support tube 3 is coaxially arranged at the center of the spiral conveying shaft 32. The support tube 3 passes through the die head 2 and extends to the traction assembly 4. By setting the spiral conveying shaft 32, the support tube 3 can be supported. The remaining positions of the support tube 3 can also be supported by the traction assembly 4, the guide seat 19 and the rotating disk 8 after cooperating with the plastic pipe to prevent the bending problem caused by the bending of the support tube 3.

[0029] In this embodiment, at least one cooling assembly 33 is axially arranged on the outer side of the feeding pipe 31. The cooling assembly 33 is a cooling pipe. The outer side of the cooling pipe can be connected to the cold air generating device through a pipeline.

[0030] In this embodiment, a cutting assembly 34 is provided on the side of the traction assembly 4 away from the extruder 1. The cutting assembly 34 includes a cutting turntable 35, a fourth motor 36, a motor support 37, a transverse slider 38, a transverse guide rail 39, and a linear motor 40. The cutting turntable 35 is coaxially connected to the output shaft of the fourth motor 36. The fourth motor 36 is fixedly arranged on the motor support 37. The motor support 37 is fixedly connected to the transverse slider 38. The transverse slider 38 slides with the transverse guide rail 39, and the transverse guide rail 39 is connected to the output end of the linear motor 40.

[0031] In this embodiment, a cold air nozzle 41 is provided at the outer end of the support tube 3 . The cold air nozzle 41 is connected to the cold air generating device, and the nozzle of the cold air nozzle 41 faces the support tube 3 .

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
