[0002] A surface grinding device for steel-plastic composite pipes is a device specifically used for grinding the surface of steel-plastic composite pipes. The steel-plastic composite pipe consists of an inner layer of plastic and an outer layer of steel, and this composite pipe is commonly used in application scenarios that require both strength and corrosion resistance. To ensure that the surface of the pipe reaches the required smoothness and processing effect, this grinding device adopts various technical means and design features. Specifically, the grinding device may include multiple adjustable grinding components, such as rotary brushes, grinding wheels or abrasive belts, which can be adjusted according to the diameter and surface condition of the pipe to achieve uniform and efficient grinding. The device may also be equipped with an automatic feeding system to ensure that the pipe material maintains a stable speed and position during the grinding process, thereby improving the processing accuracy;

[0003] After retrieval, the Chinese patent with the publication number of CN208811723U discloses a surface grinding device for steel-plastic composite pipes. The patent records that the second motor drives the rotating shaft to drive the plate to rotate simultaneously, which can drive the steel-plastic composite pipe to rotate in the groove, ensuring that the steel-plastic composite pipe can be ground in multiple aspects. Its grinding method is relatively flexible, with low usage limitations, strong usage effects, and high practicability; moreover, the wind generated by the blower can transport the metal debris in the support table to the recycling box, and its working mode is relatively diverse, facilitating the handling of the debris generated during the grinding process, thereby improving its usage reliability.

Moreover, sliding or shaking of the steel-plastic composite pipe during grinding will directly affect the grinding effect and cause damage to the steel-plastic composite pipe, thus affecting the quality of the product. To solve this technical problem, the utility model proposes a surface grinding device for steel-plastic composite pipes. Content of the Utility Model

[0014] (3) Beneficial effects

[0015] The utility model provides a surface grinding device for steel-plastic composite pipes. It has the following beneficial effects:

[0016] (1) An electric push rod one is installed on the workbench. By pushing the base to move with it, the base is guided by the slider in the chute to ensure its stable movement. When the base moves, the connecting ring also moves accordingly and is positioned at the supporting position of the steel-plastic composite pipe body. Then, the electric push rod two starts to push the arc-shaped plate to move. The arc-shaped plate is accurately limited in the positioning block through the positioning rod to ensure that the arc-shaped plate is in the correct position. The movement of the arc-shaped plate fixes the steel-plastic composite pipe body firmly on the fixed block. The fixed block is equipped with rollers, which reduces the friction. Through the cooperation of these components, the device can quickly and accurately position and fix the steel-plastic composite pipe body, solving the problems of insufficient accuracy, excessive friction and difficult positioning in the positioning and fixing process of the traditional device, thereby improving the working efficiency and processing quality of the device.

[0017] (2) The motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the grinding cylinder to rotate at a high speed, thereby effectively grinding the workpiece to be processed. During the grinding process, the outer shell wraps the grinding cylinder to prevent the generated debris from flying everywhere. To solve the problems of heat and dust generated during the grinding process, the water pump is started to pump the water in the water tank, and it is conveyed to the vicinity of the grinding cylinder through the water supply pipe and the water passing hose to achieve cooling and dust removal. When the water flow passes through the grinding cylinder, the water flow is guided to the water leakage port through the guide plate, and the waste water then flows into the waste liquid tank for centralized collection. Through their cooperation, the device not only effectively reduces the heat and dust during the grinding process, but also realizes the rapid collection and treatment of waste water, thereby improving the safety of the working environment and the grinding efficiency, and solving the problem of debris flying in the traditional device.

[0023] 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.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] Embodiment 1: A surface grinding device for a steel-plastic composite pipe, including a workbench 1. A pair of electric push rods 1 are fixedly connected to the top of the workbench 1. The output end of each electric push rod 1 is fixedly connected with a base 3. A pair of chutes 4 are opened at the top of the workbench 1. A slider 5 is fixedly connected to the bottom of each base 3, and the slider 5 is slidably connected inside the chute 4. A connecting ring 6 is fixedly connected to the top of each base 3. Two pairs of electric push rods 2 are fixedly connected inside the connecting ring 6. The output end of each electric push rod 2 is fixedly connected with an arc plate 8. Two pairs of fixing blocks 9 are fixedly connected to the inner side wall of the arc plate 8. A roller 10 is rotatably connected between the two side fixing blocks 9. A pair of positioning blocks 11 are fixedly connected to the outer side wall of each electric push rod 2. A pair of positioning rods 12 are fixedly connected to the outer side wall of each arc plate 8. At the same time, the positioning rod 12 passes through the positioning block 11 and extends to the outside of the connecting ring 6. At the same time, the positioning rod 12 is slidably connected inside the positioning block 11 and the connecting ring 6. A steel-plastic composite pipe body 13 is arranged inside the two side connecting rings 6.

[0026] The steel-plastic composite pipe body 13 is fixed by passing through the inside of the connecting ring 6. First, start the electric push rod 1 at the top of the workbench 1 to push the base 3 to move. During the movement of the base 3, it is limited in the chute 4 by the slider 5, and at the same time drives the connecting ring 6 to move accordingly to find a suitable support point. Then, start the electric push rod 2 on the inner wall of the connecting ring 6 to push the arc plate 8 to move along its track. The arc plate 8 is limited inside the positioning block 11 by the positioning rod 12 to ensure accurate positioning. Under the action of the electric push rod 2, the arc plate 8 moves towards the outer wall of the steel-plastic composite pipe body 13 and cooperates with the roller 10 on the fixing block 9 to reduce the friction force, so as to realize the rapid positioning and stable support of the steel-plastic composite pipe body 13. Through this precise cooperation and positioning mechanism, the forward movement and shaking of the steel-plastic composite pipe body during the grinding process are avoided, thereby significantly improving the work quality and processing accuracy.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a bracket 14 is fixedly connected to the top of the workbench 1, a hydraulic cylinder 15 is fixedly connected to the top of the bracket 14, and a connecting frame 16 is fixedly connected to the output end of the hydraulic cylinder 15. A motor 18 is fixedly connected inside the connecting frame 16. At the same time, a rotating shaft 19 is fixedly connected to the output end of the motor 18, and a grinding cylinder 20 is fixedly connected to the outer wall of the other end of the rotating shaft 19. A housing 21 is fixedly connected to the outer side wall of the connecting frame 16. The grinding cylinder 20 is rotatably connected inside the housing 21. Flow guide plates 22 are fixedly connected to both sides of the housing 21. A water tank 23 is fixedly connected to the top of the workbench 1. At the same time, a water pump 25 is fixedly connected to the outside of the water tank 23, and a water passing hose 26 is fixedly connected to the output end of the water pump 25. The other end of the water passing hose 26 is inserted into the flow guide plate 22. A water leakage port 28 is opened inside the workbench 1, and a waste liquid tank 29 is arranged at the bottom of the workbench 1. At the same time, the water leakage port 28 corresponds to the flow guide plate 22, and the water leakage port 28 corresponds to the waste liquid tank 29. A water adding pipe 24 is arranged at the top of the water tank 23. A pair of limiting rods 17 are fixedly connected to the top of the connecting frame 16, and the limiting rods 17 are slidably connected inside the bracket 14. A feeding component 27 is arranged on the top of the workbench 1.

[0028] Start the hydraulic cylinder 15 at the top of the bracket 14 to push the connecting frame 16 to move. The connecting frame 16 is positioned by the limiting rods 17. When the connecting frame 16 moves, it will drive the housing 21, the motor 18 and the grinding cylinder 20 to move downward together. When the grinding cylinder 20 aligns with the outer surface of the steel-plastic composite pipe body 13, start the motor 18. The rotation of the motor 18 drives the rotating shaft 19 to rotate, and then the grinding cylinder 20 starts to rotate to grind the outer surface of the steel-plastic composite pipe body 13. The debris generated during the grinding process is effectively blocked by the housing 21. At the same time, start the water pump 25 outside the water tank 23. The water pump 25 extracts water from the water tank 23 and cools and removes dust from the grinding cylinder 20 through the water passing hose 26 to keep the grinding process clean and stable. The waste water generated by grinding is thrown towards the flow guide plate 22 under the action of the high-speed rotation of the grinding cylinder 20 and finally flows into the waste liquid tank 29 through the water leakage port 28 for collection. This system effectively avoids the possible injuries caused by the flying debris during the grinding process and realizes the rapid collection of debris and waste water, significantly improving the work efficiency and operation safety. At the same time, the existing feeding component 27 can rotate and move the steel-plastic composite pipe, further optimizing the working effect during the grinding process.

[0029] Working principle: When the staff needs to polish the outer surface of the steel-plastic composite pipe body 13, first pass the steel-plastic composite pipe body 13 through the inside of the connecting ring 6 and extend it into the feeding component 27. First, start the electric push rod 1 on the top of the workbench 1. Under the action of the electric push rod 1, the base 3 is pushed to move. When the base 3 moves, it is limited in the chute 4 through the slider 5. When the base 3 moves, it drives the connecting ring 6 to move, so as to find a suitable support point. At this time, start the electric push rod 2 on the inner wall of the connecting ring 6. Under the action of the electric push rod 2, the arc plate 8 is pushed to move. When the arc plate 8 moves, it is limited in the positioning block 11 through the positioning rod 12. At this time, the arc plate 8 moves towards the outer wall of the steel-plastic composite pipe body 13 under the action of the electric push rod 2. At the same time, the roller 10 on the fixed block 9 is used to reduce the friction during movement. Through their cooperation, the rapid positioning and fixed support of the steel-plastic composite pipe body 13 are realized, preventing forward movement and shaking during polishing, and improving the work quality. At this time, start the hydraulic cylinder 15 on the top of the bracket 14. Under the action of the hydraulic cylinder 15, the connecting frame 16 is pushed to move. The connecting frame 16 is limited by the limiting rod 17. When the connecting frame 16 moves, it drives the housing 21, the motor 18 and the polishing cylinder 20 to move down at the same time. When the polishing cylinder 20 corresponds to the outer surface of the steel-plastic composite pipe body 13, start the motor 18 at this time. Under the action of the motor 18, the rotating shaft 19 is driven to rotate. Through the rotation of the rotating shaft 19, the polishing cylinder 20 is driven to rotate, so as to start polishing the outer surface of the steel-plastic composite pipe body 13. The debris generated by polishing is blocked by the housing 21. Cooperate with starting the water pump 25 outside the water tank 23. Under the action of the water pump 25, the water inside the water tank 23 is pumped and passed through the water pipe 26 to cool and remove dust from the polishing cylinder 20. The waste water will be thrown into the guide plate 22 under the rapid rotation of the polishing cylinder 20 and drip into the water leakage port 28, and flow into the waste liquid tank 29 through the water leakage port 28 for collection. Through their cooperation, it avoids the debris from splashing and hurting the staff, and realizes the effect of rapid collection, improving the work efficiency. The steel-plastic composite pipe is rotated and moved through the existing feeding component 27.
