Description

Technical Field

[0001] This utility model relates to the field of plastic processing and pipe manufacturing technology, and in particular to a polyethylene pipe processing and coating device. Background Technology

[0002] In modern industry and infrastructure construction, polyethylene pipes are widely used in water supply and drainage, gas transmission, agricultural irrigation, municipal engineering, and many other fields due to their excellent chemical stability, flexibility, and cost advantages. However, untreated polyethylene pipes are susceptible to environmental factors during long-term use, such as corrosive substances in the soil, ultraviolet radiation, and abrasion from the transported medium, leading to a decline in pipe performance, a shortened service life, and even safety hazards such as leaks. Therefore, a polyethylene pipe processing and coating device has been developed to address this need.

[0003] The device uses a specific coating process to form one or more functional coatings on the surface of polyethylene pipes. These coatings can enhance their corrosion resistance to adapt to complex underground soil environments, improve their wear resistance to withstand long-term erosion of the transported medium, increase their UV resistance to extend their service life in outdoor environments, and optimize the sealing performance of the pipes to ensure the safe and stable operation of the transport system.

[0004] In the prior art, the pipes in some devices are prone to displacement due to their own roundness deviation or slight external disturbance, which can lead to misalignment between the pipe edge and the coating area, resulting in local missed coating or over-coating, and can also cause instability of the rotation center, resulting in significant differences in coating thickness in the circumferential direction of the pipe. To address these issues, a polyethylene pipe processing and coating device is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a polyethylene pipe processing and coating device, which aims to improve the problem in the prior art where the pipe is prone to displacement due to its own roundness deviation or slight external disturbance, which can lead to misalignment between the pipe edge and the coating area, resulting in local missed coating or over-coating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A polyethylene pipe processing and coating device includes a base plate, a mounting frame fixedly connected to the top of the base plate, multiple support legs fixedly connected to the bottom of the base plate, a motor fixedly connected to the outside of the mounting frame, an installation pipe fixedly connected to the drive end of the motor, two clamping mechanisms installed outside the installation pipe, a sliding column fixedly connected inside the mounting frame, a sliding plate slidably connected inside the sliding column, an installation mechanism installed at the bottom of the sliding plate, a support plate detachably connected to the bottom of the installation mechanism, and multiple spray nozzles fixedly connected to the bottom of the support plate. The clamping mechanism includes a support frame, a disc frame rotatably connected inside the support frame, a drive assembly fixedly connected inside the support frame, and multiple mounting columns fixedly connected to the outside of the support frame. Rotating plates are rotatably connected to the outside of each of the multiple mounting columns, and rotating wheels are rotatably connected to the inside of each of the multiple rotating plates. As a further description of the above technical solution: The drive assembly includes a second motor, a threaded rod fixedly connected to the drive end of the second motor, a fixed block fixedly connected to the outside of the threaded rod, a sliding block slidably connected to the outside of the threaded rod, and a connecting plate rotatably connected to the outside of the sliding block slidably. As a further description of the above technical solution: The installation mechanism includes an installation block 1, a connecting column is fixedly connected inside the installation block 1, a sliding block 2 is slidably connected to the outside of the connecting column, a limit block is fixedly connected to the outside of the connecting column, and the installation block 2 is detachably connected to the outside of the installation block 1. As a further description of the above technical solution: The second mounting block has a groove inside, and multiple support blocks are fixedly connected inside the second mounting block. Springs are fixedly connected to the outside of each of the multiple support blocks, and the other end of each spring is fixedly connected to the second fixing block. As a further description of the above technical solution: The disc frame has multiple grooves inside, the rotating plate is rotatably connected to the inside of the disc frame, and the rotating wheel is rotatably connected to the outside of the mounting tube. As a further description of the above technical solution: The fixing block is externally fixedly connected to the outside of the support frame, and the connecting plate is externally fixedly connected to the outside of the disc frame. As a further description of the above technical solution: The first mounting block is fixedly connected to the outside of the sliding plate, and the second mounting block is detachably connected to the outside of the support plate. As a further description of the above technical solution: The second fixing block is externally slidably connected to the inside of the second mounting block, and the second fixing block is externally slidably connected to the outside of the connecting column.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the second motor drives the threaded rod to rotate. The rotation of the threaded rod causes the first sliding block to move outside the threaded rod. The first sliding block drives the connecting plate to move, which in turn causes the connecting plate to drive the disc frame to rotate. When the disc frame rotates, it drives the rotating plate to rotate inside the disc frame. When multiple rotating plates rotate, they clamp the installation pipe, which can effectively avoid the problems of axial deviation, radial shaking or bending and sagging of the pipe during the coating process. This allows the coating to be evenly adhered to every area of ​​the pipe surface, reducing defects such as local overcoating, missed coating, and sagging caused by changes in the position of the pipe, and ensuring the stability of the coating quality from the source.

[0008] 2. In this utility model, by moving the second mounting block, the spring is compressed according to its own elastic properties, thereby driving the second fixed block to slide, and then the second fixed block and the second sliding block come into contact, so that the second sliding block slides outside the connecting column. When it comes into contact with the limiting block, the second fixed block disengages from the contact of the second sliding block, and the second sliding block slides back to its original position. At this time, the second mounting block disengages from the locking position, so that the nozzle can be disassembled and replaced, thereby realizing the quick installation and removal of the nozzle. Replacement or disassembly and maintenance can be completed without complicated tools, significantly shortening downtime and improving the effective operating rate of the equipment.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of a polyethylene pipe processing and coating device, including a base plate 1, a mounting frame 2 fixedly connected to the top of the base plate 1, and multiple support legs 3 fixedly connected to the bottom of the base plate 1. The support legs 3 are used to support the entire device and ensure the stability of the device during operation. A motor 4 is fixedly connected to the outside of the mounting frame 2. An installation pipe 5 is fixedly connected to the drive end of the motor 4. When the motor 4 starts, the drive end drives the installation pipe 5 to rotate, so that the pipe on the installation pipe 5 rotates accordingly, which facilitates the spray head 11 to coat the pipe in all directions. Two clamping mechanisms 6 are installed on the outside of the installation pipe 5. The two clamping mechanisms 6 clamp the pipe from different positions to enhance the stability of the clamping.

[0013] The mounting bracket 2 has a sliding column 7 fixedly connected inside. The sliding column 7 provides guidance and support for the sliding plate 8, ensuring that the sliding plate 8 moves smoothly. The sliding plate 8 is slidably connected inside the sliding column 7. The movement of the sliding plate 8 can drive the mounting mechanism 9 and the nozzle 11 to move, adjusting the relative position of the nozzle 11 and the pipe to adapt to the coating requirements of pipes of different lengths. The mounting mechanism 9 is installed at the bottom of the sliding plate 8. The mounting mechanism 9 is used to install and fix the support plate 10 and the nozzle 11, and at the same time facilitates the disassembly and replacement of the nozzle 11. The support plate 10 is detachably connected to the bottom of the mounting mechanism 9. The support plate 10 provides an installation platform for multiple nozzles 11, making the nozzle 11 layout more reasonable. Multiple nozzles 11 are fixedly connected to the bottom of the support plate 10. The simultaneous operation of multiple nozzles 11 can improve coating efficiency and ensure coating uniformity.

[0014] The clamping mechanism 6 includes a support frame 61, which provides a mounting base for other components of the clamping mechanism 6, ensuring the stability of each component's position. A disc frame 62 is rotatably connected inside the support frame 61. When the disc frame 62 rotates, it can drive the rotating plate 65 to move, thereby clamping or releasing the mounting tube 5. A drive assembly 63 is fixedly connected inside the support frame 61, which provides power for the rotation of the disc frame 62, ensuring that the clamping action is carried out in an orderly manner. Multiple mounting columns 64 are fixedly connected to the outside of the support frame 61. The mounting columns 64 provide a rotation fulcrum for the rotating plate 65, ensuring that the rotating plate 65 can rotate flexibly. The rotating plates 65 are rotatably connected to the outside of the multiple mounting columns 64. The rotating plates 65 rotate under the drive of the disc frame 62, thereby driving the rotating wheel 66 to move closer to or away from the mounting tube 5, thereby clamping or releasing.

[0015] Multiple rotating plates 65 are each rotatably connected to rotating wheels 66. When the rotating wheels 66 contact the mounting tube 5, they rotate with the mounting tube 5, reducing frictional damage to the surface of the mounting tube 5. The drive assembly 63 includes a second motor 631, which is the power source for the drive assembly 63, providing power for the rotation of the threaded rod 632. The drive end of the second motor 631 is fixedly connected to the threaded rod 632. When the second motor 631 starts, the drive end drives the threaded rod 632 to rotate, causing the sliding block 634 to move on the threaded rod 632. The external fixed connection is a fixed block 633, which can limit the movement range of the sliding block 634 and prevent the sliding block 634 from disengaging from the threaded rod 632. The external sliding connection of the threaded rod 632 is the sliding block 634. When the sliding block 634 moves on the threaded rod 632, it drives the connecting plate 635 to move, thereby driving the disc frame 62 to rotate. The external rotating connection of the sliding block 634 is the connecting plate 635, which converts the linear motion of the sliding block 634 into the rotational motion of the disc frame 62, thereby realizing power transmission.

[0016] The disc frame 62 has multiple grooves inside, which provide space for the rotation of the rotating plate 65 and prevent interference between the rotating plate 65 and the disc frame 62 during movement. The rotating plate 65 is externally rotatably connected to the inside of the disc frame 62, so that the rotating plate 65 can rotate synchronously under the drive of the disc frame 62 to clamp the mounting tube 5. The rotating wheel 66 is externally rotatably connected to the outside of the mounting tube 5. The contact between the rotating wheel 66 and the mounting tube 5 achieves clamping of the tube and reduces friction. The fixing block 633 is externally fixedly connected to the outside of the support frame 61, fixing the drive component 63 to the support frame 61 and ensuring the stability of the drive component 63 during operation. The connecting plate 635 is externally fixedly connected to the outside of the disc frame 62, so that the connecting plate 635 can effectively drive the disc frame 62 to rotate and ensure the effective execution of the clamping action.

[0017] Reference Figure 1 , Figure 4 and Figure 5 The installation mechanism 9 includes a first installation block 91, which provides an installation base for other components of the installation mechanism 9. A second sliding block 93 is slidably connected to the outside of the connecting column 92. When the second sliding block 93 slides on the connecting column 92, it cooperates with the second fixing block 98 to connect or separate the first installation block 91 and the second installation block 95. A limit block 94 is fixedly connected to the outside of the connecting column 92. The limit block 94 can limit the sliding range of the second sliding block 93 and prevent the second sliding block 93 from detaching from the connecting column 92. The second installation block 95 is detachably connected to the outside of the first installation block 91. The detachable connection between the second installation block 95 and the first installation block 91 facilitates the disassembly and replacement of the support plate 10 and the nozzle 11. A groove is provided inside the second installation block 95. The groove provides space for the sliding of the second fixing block 98 and ensures that the second fixing block 98 can move normally.

[0018] Multiple support blocks 96 are internally fixedly connected to mounting block 2 95. Support blocks 96 provide fixed fulcrums for spring 97, ensuring stable operation of spring 97. Springs 97 are externally fixedly connected to each of the support blocks 96. Springs 97, through their elasticity, drive fixing block 2 98 to reset, thus fixing mounting block 1 91 to mounting block 2 95. Fixing block 2 98 is fixedly connected to the other end of each spring 97. Fixing block 2 98, under the action of spring 97, contacts or separates from sliding block 2 93, locking or unlocking mounting block 1 91 and mounting block 2 95. The external fixed connection of mounting block 1 91 to the sliding block 2 95... The external of the movable plate 8 allows the mounting mechanism 9 to move together with the sliding plate 8, adjusting the position of the nozzle 11. The external of the second mounting block 95 is detachably connected to the external of the support plate 10, facilitating the installation and removal of the support plate 10 and the nozzle 11. The external of the second fixing block 98 is slidably connected to the internal of the second mounting block 95, allowing the second fixing block 98 to slide flexibly within the second mounting block 95, ensuring smooth locking and unlocking. The external of the second fixing block 98 is slidably connected to the external of the connecting post 92. When the second fixing block 98 contacts the connecting post 92, it enhances the stability of the connection between the first mounting block 91 and the second mounting block 95.

[0019] Working principle: When clamping the pipe, the clamping mechanism 6 first starts working, and the second motor 631 starts. When the second motor 631 starts, its drive end starts to drive the threaded rod 632 to rotate. The rotation of the threaded rod 632 causes the sliding block 634 to move outside the threaded rod 632. While the sliding block 634 is moving, it drives the connecting plate 635 to move. The connecting plate 635 is connected to the disc frame 62, which in turn drives the disc frame 62 to rotate. When the disc frame 62 rotates, it drives the rotating plate 65 to rotate inside the disc frame 62. When multiple rotating plates 65 rotate, they clamp the installation pipe 5, which can effectively avoid the problems of axial deviation, radial shaking or bending and sagging of the pipe during the coating process. This allows the coating to be evenly adhered to every area of ​​the pipe surface, reducing defects such as local overcoating, missed coating, and sagging caused by changes in the position of the pipe, and ensuring the stability of the coating quality from the source.

[0020] When disassembling and replacing the nozzle 11, firstly, the second mounting block 95 is moved. When the second mounting block 95 moves, the spring 97 is compressed according to its own elasticity, thereby driving the second fixed block 98 to slide, which in turn makes the second fixed block 98 contact the second sliding block 93. This allows the second sliding block 93 to slide outside the connecting column 92. When it contacts the limit block 94, the second fixed block 98 disengages from the contact of the second sliding block 93, and the second sliding block 93 slides back to its original position. At this time, the second mounting block 95 disengages, allowing the nozzle 11 to be disassembled and replaced. This achieves quick installation and removal of the nozzle 11, and replacement or disassembly maintenance can be completed without complicated tools, significantly shortening downtime and improving the effective operating rate of the equipment. At the same time, different nozzles 11 can be switched through simple operation, enabling the equipment to quickly respond to diverse production needs and improving the flexible production capability of the equipment.
