[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figure 1-5 As shown, a surface coating device for polyethylene pipe production includes: a top plate 1, a bottom plate 2 below the top plate 1, multiple support columns 3 symmetrically installed at the bottom edge of the top plate 1, the bottom ends of the support columns 3 connected to the bottom plate 2, a clamping assembly 4 for positioning and fixing polyethylene pipes on the top of the top plate 1, which can position and fix the polyethylene pipes from both ends and rotate them after positioning and fixing, thus facilitating subsequent coating work; and a collection tray 30, located on the top of the top plate 1, with a side panel for performing the polyethylene pipe surface coating process. The spraying component 12, together with the clamping component 4, can achieve complete spraying of the outer surface of the polyethylene pipe. At the same time, the collection tray 30 located at the top of the top plate 1 can also collect the fallen paint, thereby avoiding paint turbulence and affecting the production environment. On the other side of the collection tray 30, there is a lifting component 17 to replace manual handling of the polyethylene pipe and reduce the difficulty of loading. By setting the lifting component 17, the machine can replace manual handling of the polyethylene pipe to be coated, thereby simplifying the loading process, reducing the difficulty of loading, and enabling the polyethylene pipe to be better positioned and fixed for outer surface spraying.

[0018] The clamping assembly 4 includes a first pipe support 41 fixed to the top of one end of the top plate 1, and a second pipe support 42 located at the top of the other end of the top plate 1. Both the first pipe support 41 and the second pipe support 42 are rotatably connected to a rotating shaft 43. Hydraulic chucks 45 are fixedly mounted at the ends of the two rotating shafts 43 that are close to each other. A first motor 44 is fixedly mounted on one side of the first pipe support 41. One end of one of the rotating shafts 43 passes through the first pipe support 41 and is connected to the output end of the first motor 44. Figure 1 , Figure 3 As shown, it should be noted that the hydraulic chuck 45 is a commonly used workpiece clamping device in the prior art. It can realize the conversion of axial force to radial clamping force through hydraulic drive of the wedge mechanism, thereby completing the rapid clamping or release of the workpiece. In actual use, by operating the multiple jaws on the outside of the hydraulic chuck 45 to expand outward, it can be positioned and fixed from the inner walls of both ends of the polyethylene pipe to be coated. When the coating work is carried out, the first motor 44 and the rotating shaft 43 can drive the polyethylene pipe between the hydraulic chuck 45 to rotate as a whole. With the help of the spraying assembly 12, the outer surface of the polyethylene pipe can be completely sprayed.

[0019] A guide groove 5 is provided inside the top plate 1, located below the second pipe support 42. A quadrilateral frame 6 is fixedly connected to the bottom of the guide groove 5. A ball screw 9 is provided inside the quadrilateral frame 6, and the ball screw 9 is rotatably connected to both sides of the inner wall of the quadrilateral frame 6 via bearings. A screw nut 7 is helically connected to the outer side of the ball screw 9, and the top of the screw nut 7 is connected to the second pipe support 42. A second motor 8 is fixedly installed on one side of the quadrilateral frame 6. One end of the ball screw 9 passes through the quadrilateral frame 6 and is connected to the output end of the second motor 8. First sliders 10 are fixedly connected to both sides of the screw nut 7. A first groove 11 corresponding to the first slider 10 is provided on the inner wall of the quadrilateral frame 6, and the first slider 10 is located inside the first groove 11. Figure 1 , Figure 2 and Figure 3 As shown, the second motor 8 and ball screw 9 can drive the second pipe support 42 on the top of the screw block 7 to move closer to the first pipe support 41, thereby achieving the positioning and fixing of the polyethylene pipe to be coated between the first pipe support 41 and the second pipe support 42, which facilitates the polyethylene pipe coating work.

[0020] The spraying assembly 12 includes a liquid storage tank 121 disposed at one end of the top plate 1. The bottom of the liquid storage tank 121 is connected to the bottom plate 2. A base 122 is fixedly connected to the top of one side of the bottom plate 2. A column 123 is disposed above the base 122. An atomizing nozzle 124 is fixedly installed at the top of the column 123. One end of the atomizing nozzle 124 is connected to an inlet bend 125. A liquid injection port 128 is disposed at the top of one side of the liquid storage tank 121. A paint pump 127 is fixedly installed at the bottom of one side of the liquid storage tank 121. The inlet of the paint pump 127 is connected to the inside of the liquid storage tank 121. The outlet of the paint pump 127 is connected to an inlet hose 126. One end of the inlet hose 126 is connected to the inlet bend 125. Figure 1 , Figure 3 As shown, the paint pump 127 can drive the paint inside the storage tank 121 through the inlet hose 126 and the inlet bend 125 to the inside of the atomizing nozzle 124. The atomizing nozzle 124 then evenly sprays the paint onto the outer surface of the rotating polyethylene pipe, thereby achieving complete coating of the outer surface of the polyethylene pipe. At the same time, the paint can be replenished to the storage tank 121 through the injection port 128, thus ensuring the steady progress of the polyethylene pipe coating work.

[0021] A motor guide rail 13 is provided on the top of the base 122. A linear motor 14 is slidably mounted on the outer side of the motor guide rail 13. The bottom end of the column 123 is connected to the linear motor 14. A sliding column 15 is slidably connected inside the column 123. A fixed seat 16 is fixedly connected to one side of the top plate 1. The sliding column 15 is connected to the fixed seat 16 and the liquid storage tank 121 respectively. Figure 1 , Figure 3 As shown, it should be noted that the linear motor 14 is a device that directly converts electrical energy into linear motion mechanical energy. Its core function is to drive the load to move in a straight line through electromagnetic force, thereby achieving precise positioning and driving. In actual use, the linear motor 14 can drive the atomizing nozzle 124 to move back and forth along the length of the motor guide rail 13. In conjunction with the first motor 44, it drives the polyethylene pipe that has been positioned and fixed to rotate. This allows the atomizing nozzle 124 to spray onto any position on the outer surface of the polyethylene pipe, thus ensuring that the paint can be completely coated on the outer surface of the polyethylene pipe.

[0022] The lifting assembly 17 includes a support plate 171 disposed above the base plate 2. Vertical plates 172 are vertically mounted on the top of both sides of the support plate 171. A quadrilateral frame 173 is provided between the vertical plates 172. A lifting plate 174 is fixedly connected to one side of the quadrilateral frame 173. A horizontal plate 175 is vertically mounted on one side of the lifting plate 174. A placement seat 176 is fixedly mounted on the top of the horizontal plate 175. Figure 3 , Figure 4 As shown, in the initial state, the quadrilateral frame 173 is located at a low position. When loading polyethylene pipes, workers can place the polyethylene pipes into the placement seat 176, and then use the quadrilateral frame 173, lifting plate 174, and horizontal plate 175 to lift the placement seat 176 and the polyethylene pipes to the same height as the clamping assembly 4. This replaces manual handling of the polyethylene pipes to be coated, reducing the workload of workers.

[0023] An electric hoist 18 is fixedly installed on the top of one side of the support plate 171. A wire rope 19 is provided on the outside of the electric hoist 18. The top of the wire rope 19 is connected to the quadrilateral frame 173. A guide wheel 20 is provided above the quadrilateral frame 173. L-shaped plates 21 are provided on both sides of the guide wheel 20. One end of the L-shaped plate 21 is connected to the vertical plate 172. The guide wheel 20 is rotatably connected to the L-shaped plates 21 on both sides through bearings. A connecting plate 24 is provided above the guide wheel 20. The connecting plate 24 is connected to the vertical plates 172 at both ends. A second slider 22 is fixedly connected to both sides of the quadrilateral frame 173. A second groove 23 corresponding to the second slider 22 is opened on the inner wall of the vertical plate 172. The second slider 22 is located inside the second groove 23. Figure 4 , Figure 5 As shown, after the polyethylene pipe is placed inside the placement seat 176, the electric hoist 18 can be used to wind up the wire rope 19. After passing the guide wheel 20, the wire rope 19 can drive the polyethylene pipe to rise to the same height as the clamping assembly 4, which facilitates the subsequent positioning and fixing of the polyethylene pipe. At the same time, by setting the second slider 22 and the second slide groove 23, the polyethylene pipe can be kept smooth during the lifting and displacement process, which is conducive to improving the working stability of the lifting assembly 17.

[0024] A third motor 26 is fixedly installed at the bottom of the support plate 171. Side plates 25 are provided on both sides of the third motor 26. The top of the side plates 25 is connected to the support plate 171. The output end of the third motor 26 extends through to the outside of the side plates 25 and is fixedly connected to a main traveling wheel 27. Auxiliary traveling wheels 28 are provided on both sides of the main traveling wheel 27. One end of each auxiliary traveling wheel 28 is rotatably connected to the side plate 25. A limiting groove 29 corresponding to the main traveling wheel 27 is provided on the top of the base plate 2. Figure 4 , Figure 5 As shown, it should be noted that the third motor 26 is a dual-axis motor. After the polyethylene pipe is lifted, the third motor 26 can drive the main traveling wheel 27 to rotate. The main traveling wheel 27, together with the auxiliary traveling wheel 28, can drive the support plate 171 to move closer to the top plate 1 until the polyethylene pipe and the axis of the hydraulic chuck 45 are aligned to achieve the centering operation. Compared with the common method of manually handling polyethylene pipes for loading, this simplifies the loading process, reduces the difficulty of loading, and reduces the workload of the workers. It also allows the polyethylene pipe to be better positioned and fixed and to be sprayed on the outer surface.

[0025] Working principle: First, the lifting component 17 allows the machine to move the polyethylene pipe to be coated, which simplifies the loading process, reduces the difficulty of loading, and reduces the workload of the workers. After the axis of the polyethylene pipe is aligned with that of the hydraulic chuck 45, the clamping component 4 can position and fix the polyethylene pipe from both ends. Then, with the help of the spraying component 12, the outer surface of the polyethylene pipe in the rotating state can be completely sprayed. At the same time, the collection tray 30 on the top of the top plate 1 can also collect the fallen paint to avoid the paint flowing around and affecting the production environment.
