An arc-shaped pressing plate is arranged on the vibration rotating disc in a radial sliding mode through a second spring. The bidirectional damper can generate a hysteresis effect on the movement of the sliding plate in any direction, so that the movement of the sliding plate always lags behind a water pipe wound on the reel, and the hysteresis property enables the water pipe on the sliding plate to always bear a force opposite to the winding direction of the reel, so that generation of a gap is effectively avoided, and the service life of the water pipe is prolonged. And the arc-shaped pressing plate on the vibration rotating disc can continuously hit the water pipe, so that the water pipe continuously vibrates, and the problem that adjacent water pipes are mutually laminated is avoided.

Description

Technical Field

[0001] The present invention belongs to the technical field of sprinklers, and specifically refers to a pipe winding device for a sprinkler. Background Art

[0002] During the assembly process before the sprinkler leaves the factory, the winding process of the PE water pipe is a key link. The currently adopted winding method has obvious technical defects: as the number of layers on the reel increases, the winding radius of the water pipe gradually increases, which directly causes the winding linear speed to increase linearly. This non-constant winding speed will cause a series of problems.

[0003] First of all, due to the unstable speed, the water pipe is prone to disordered arrangement during the winding process. Specifically, there are irregular gaps between the water pipes on the same layer, or the adjacent water pipes are overlapped with each other. This disordered pipe phenomenon not only affects the appearance quality of the product, but also reduces the service life of the water pipe.

[0004] Secondly, in order to ensure the winding quality, the operator must closely monitor the winding process throughout the whole process and frequently use tools to straighten and adjust the water pipe, which increases the labor intensity and production cost and seriously restricts the production efficiency.

[0005] More notably, this unstable winding process may cause uneven stress distribution on the water pipe, which may affect the physical properties of the pipe material in the long run. At the same time, the quality fluctuations caused by manual intervention are also inevitable, bringing challenges to product quality control. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a pipe winding device for a sprinkler, which at least partially solves the above problems.

[0007] The technical solution adopted by the present invention is as follows: A pipe winding device for a sprinkler proposed by the present invention includes a slide plate configured to reciprocate in a direction perpendicular to its plate surface. A wheel set is rotatably provided on the slide plate. A tensioning wheel is slidably connected to the slide plate through a first spring. The wheel set and the tensioning wheel are used to guide the water pipe; A two-way damper, including a telescopic rod and a piston. The telescopic rod is provided on the plate surface of the slide plate. The piston is provided on the telescopic rod. An exchange hole is provided on the piston; A vibrating turntable configured to be driven to rotate. An arc-shaped pressing plate is radially slidably provided on the vibrating turntable through a second spring. The arc-shaped pressing plate is in continuous vibrating contact with the water pipe.

[0008] In some embodiments, a first guide wheel is rotatably provided on the slide plate. A second guide wheel is rotatably provided obliquely below the first guide wheel. The tensioning wheel is slidably provided above the second guide wheel.

[0009] In some embodiments, a pipe winding device of a sprinkler irrigation machine proposed by the present invention further includes a wire arranging bracket. The sliding plate is slidably arranged on the wire arranging bracket. A reciprocating lead screw is arranged on the wire arranging bracket. A guiding column is arranged inside the reciprocating lead screw. Both the guiding column and the reciprocating lead screw penetrate through the sliding plate. The reciprocating lead screw is used to drive the sliding plate to move back and forth.

[0010] In some embodiments, the bidirectional damper is fixed on the wire arranging bracket.

[0011] In some embodiments, a pipe winding device of a sprinkler irrigation machine proposed by the present invention further includes a rolling bracket and a reel. The rolling bracket is arranged on one side of the sliding plate. The reel is rotatably arranged on the rolling bracket. A pipe joint is arranged on the reel.

[0012] In some embodiments, mounting blocks are symmetrically embedded on both sides of the rolling bracket. The reel is rotatably arranged in the mounting blocks.

[0013] In some embodiments, a driven wheel is fixed on the side wall of the reel. A winding motor is fixed on the rolling bracket. A driving wheel is arranged on the output shaft of the winding motor. The driving wheel meshes with the driven wheel.

[0014] In some embodiments, a vibration motor is arranged on the sliding plate. The output shaft of the vibration motor penetrates through the sliding plate and is arranged on a vibration turntable.

[0015] The beneficial effects achieved by the present invention are as follows: 1. The bidirectional damper can produce a hysteresis effect on the movement of the sliding plate in any direction, making its movement always lag behind the water pipe wound on the reel. This lag makes the water pipe on the sliding plate always receive a force opposite to the winding direction of the reel, thereby promoting the continuously winding water pipe to continuously approach the adjacent water pipe. The adjacent water pipes can be closely attached to each other, effectively avoiding the generation of gaps. 2. The tensioning wheel can slide on the sliding plate, and its sliding distance is greater than the difference between the maximum winding radius and the minimum winding radius. When sliding in this area, the tensioning wheel can adapt to the change of the winding linear speed, keep the water pipe always tense and evenly stressed, and avoid the influence of winding stress fluctuation on the physical properties of the water pipe. 3. The arc-shaped pressing plate on the vibration turntable can continuously strike the water pipe, making the water pipe continuously vibrate, and avoiding the problem that adjacent water pipes are mutually overlapped.

[0019] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation manners

[0020] 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; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0022] As Figures 1-3 shown, a pipe winding device of a sprinkler provided by an embodiment of the present invention includes a slide plate 8, a bi-directional damper 11, and a vibration turntable 13. The slide plate 8 is configured to reciprocate along a direction perpendicular to its plate surface. A wheel set is rotatably provided on the slide plate 8. The water pipe is placed in the groove of the wheel set. There is a groove at the upper end of the slide plate 8. A tensioning wheel 17 is slidably provided in the groove at the upper end of the slide plate 8. A first spring 18 is connected between the side wall of the groove of the slide plate 8 and the tensioning wheel 17. The first spring 18 always pushes the tensioning wheel 17 in the direction of the water pipe incoming material. While the tensioning wheel 17 slides in the groove, it can also rotate itself. Both the wheel set and the tensioning wheel 17 are used to guide the water pipe, and the water pipe forms asFigure 3 The path shown is L. It should be noted that the sliding stroke of the tension pulley 17 in the groove should be greater than the difference between the maximum winding radius and the minimum winding radius of the water pipe. When sliding in this area, the tension pulley 17 can adapt to the change of the winding line speed and automatically slide to an appropriate position, avoiding excessive stretching of the water pipe due to the speed difference between winding and feeding, making the stress on the water pipe uniform and avoiding the influence of winding stress fluctuation on the physical properties of the water pipe.

[0023] In some embodiments, a rolling bracket 1 is provided on one side of the sliding plate 8. A winding disc 2 is rotatably provided on the rolling bracket 1. A pipe joint 14 is provided on the winding disc 2. One end of the water pipe needs to be fixed in the pipe joint 14 before winding. The pipe joint 14 is both the water inlet end and the fixed end.

[0024] In some embodiments, mounting blocks 6 are symmetrically embedded on both sides of the rolling bracket 1. The winding disc 2 is rotatably arranged in the mounting blocks 6. Since the volume and weight of the winding disc 2 are relatively large, it is not convenient to hoist and disassemble by directly fixing it on the rolling bracket 1. Therefore, through the fitting mounting blocks 6, the winding disc 2 can be pre-installed outside the line, and then the winding disc 2 and the mounting blocks 6 are simultaneously embedded into the rolling bracket 1. This connection method is convenient for material replacement and model change processing, which is convenient and fast.

[0025] In some embodiments, a driven wheel 3 is fixed on the side wall of the winding disc 2, and a winding motor 5 is fixed on the rolling bracket 1. A driving wheel 4 is provided on the output shaft of the winding motor 5. The driving wheel 4 meshes with the driven wheel 3. When the winding motor 5 is started, the winding disc 2 is driven to rotate through the driving wheel 4 and the driven wheel 3. When the winding disc 2 rotates, it will drive the water pipe connected to the pipe joint 14 to rotate together. During the rotation process, the water pipe is simultaneously driven to wind.

[0026] As Figure 4 shown, the inside of the two-way damper 11 includes a telescopic rod 19 and a piston 20. The telescopic rod 19 is arranged on the plate surface of the sliding plate 8, the piston 20 is arranged on the telescopic rod 19, an exchange hole 21 is provided on the piston 20, and both sides of the piston 20 are filled with hydraulic oil. When the sliding plate 8 compresses the telescopic rod 19 and slides, the telescopic rod 19 drives the piston 20 to reciprocate. Since the size of the exchange hole 21 on the piston 20 is small, the hydraulic oil on both sides of the piston 20 cannot flow quickly, and its flow rate is limited by the cross-section of the piston 20 and the aperture of the exchange hole 21. There will be obvious hysteresis in the flow of the hydraulic oil, so as to achieve the effect of continuous damping, and this damping phenomenon is not limited by direction and position. When the sliding plate 8 moves, it will always be blocked, and the water pipe in the wheel set and the tension pulley 17 will always lag behind the water pipe wound on the winding disc 2. This lag makes the water pipe on the sliding plate 8 always receive a force opposite to the winding direction of the winding disc 2, thereby promoting the continuously winding water pipe to continuously approach the adjacent water pipe, and the adjacent water pipes can be closely attached to each other, effectively avoiding the generation of gaps.

[0027] AsFigure 2 and Figure 5 As shown in Figure 5 , the vibrating turntable 13 is rotatably arranged on the side wall of the sliding plate 8. A vibrating motor 12 is arranged on the sliding plate 8. The output shaft of the vibrating motor 12 penetrates through the sliding plate 8 and is arranged on the vibrating turntable 13. And the vibrating turntable 13 is located above the tension pulley 17. A plurality of arc-shaped pressing plates 22 are slidably arranged on the circumferential side of the vibrating turntable 13. The arc-shaped pressing plates 22 slide along the radial direction of the vibrating turntable 13. A second spring 23 is connected between the arc-shaped pressing plate 22 and the vibrating turntable 13. The second spring 23 always pushes the arc-shaped pressing plate 22 outward. When the water pipe is wound on the reel 2 to different diameters, the tangency angle of the water pipe relative to the tension pulley 17 is also different, and the position angle of the water pipe relative to the vibrating turntable 13 is also different. When the vibrating motor 12 rotates, it will drive the arc-shaped pressing plate 22 to rotate. The arc-shaped pressing plate 22 extends outward to the position in contact with the water pipe under the action of the second spring 23 and is blocked by the water pipe. The arc design of the arc-shaped pressing plate 22 can avoid damaging the water pipe when contacting it. The spaced arc-shaped pressing plates 22 periodically apply pressure to the water pipe, so that the water pipe generates vibration. When the side walls of adjacent water pipes start to overlap, the vibration will cause them to slide off again, avoiding the mutual overlap of adjacent water pipes.

[0028] In some embodiments, as Figure 3 shown in Figure 3 , a first guide wheel 15 is rotatably arranged on the sliding plate 8. A second guide wheel 16 is rotatably arranged obliquely below the first guide wheel 15. The tension pulley 17 is slidably arranged above the second guide wheel 16. The obliquely arranged second guide wheel 16 can provide enough sliding stroke for the tension pulley 17 to adapt to the change of the winding diameter of the water pipe on the reel 2.

[0029] In some embodiments, as Figure 1 shown in Figure 1 , a pipe arranging bracket 7 is further included in a pipe winding device of a sprinkler irrigation machine proposed by an embodiment of the present invention. The sliding plate 8 is slidably arranged on the pipe arranging bracket 7. A reciprocating lead screw 9 is arranged on the pipe arranging bracket 7. The reciprocating lead screw 9 is configured to be driven by external power. A guide post 10 is arranged inside the reciprocating lead screw 9. Both the guide post 10 and the reciprocating lead screw 9 penetrate through the sliding plate 8. When the reciprocating lead screw 9 rotates, it drives the sliding plate 8 to slide periodically back and forth. A bidirectional damper 11 is fixed on the pipe arranging bracket 7. The stroke of the bidirectional damper 11 is greater than the winding length of the reel 2.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0031] The above describes the present invention and its embodiments. Such a description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the spirit of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
