At this time, the adjusting block will move downward due to gravity. At this time, the connecting frame in contact with the adjusting block will also rotate downward, so that the connecting frame can be tilted, so that the pipe on the connecting frame can be discharged. When the adjusting block moves downward, it will push the gas in the hollow block from the connecting pipe into the connecting groove.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figures 1 to 5 As shown, the production equipment of ultra-high molecular polyethylene pipes described in the embodiment of the present invention includes a workbench 1 and a cutting mechanism; the inner wall of the workbench 1 is provided with a connecting frame 8, and the inner wall of the connecting frame 8 is fixedly connected with two groups of connecting frames 9 arranged symmetrically, and the end of the connecting frame 9 away from the inner wall of the connecting frame 8 is rotatably connected with a roller 10, and the pipe can be placed on the roller 10, and the workbench 1 is provided with an inclined structure for tilting the connecting frame 8; the cutting mechanism includes a moving groove 2 opened on both sides of the workbench 1, and a driving wheel 4 is slidably connected in the moving groove 2, and the top surface of the driving wheel 4 is provided with a first motor for driving the driving wheel 4 to rotate, and the top surface of the first motor is fixedly connected with a mounting plate 3 through a bracket; the bottom surface of the mounting plate 3 is fixedly connected with an electric telescopic rod 5, and the output end of the electric telescopic rod 5 is fixedly connected with a mounting block 6, and the inner wall of the mounting block 6 is installed with a blade 7, and the side wall of the mounting block 6 is provided with a second motor for driving the blade 7 to rotate;

[0035] When the present application is cutting the polyethylene pipe, the polyethylene pipe can be placed on the connecting frame 8, at which time the polyethylene pipe will contact the roller 10, and then the driving wheel 4 is driven to rotate by the first motor, thereby driving the mounting plate 3 to move. After the mounting plate 3 moves to a suitable position, the pipe can be cut to meet the needs of cutting the pipe into sections of different standard lengths, and then the electric telescopic rod 5 can be started to allow the output end to push the blade 7 to move downward, while the second motor drives the blade 7 to rotate, so that the blade 7 completes the cutting of the pipe, and then the mounting plate 3 continues to move to the next position, and the blade 7 continues to be used to cut the pipe. After the pipe cutting is completed, the connecting frame 8 can be tilted with the help of a tilting mechanism, causing the pipe to slide off the connecting frame 8 under the action of the roller 10, thereby realizing the discharge work.

[0036] The tilting structure includes a hollow block 21 fixedly connected to the bottom surface of the inner wall of the workbench 1, the top surface of the hollow block 21 is sealed and slidably connected with an adjusting block 22, the top surface of the adjusting block 22 is in contact with the connecting frame 8, the connecting frame 8 is rotatably connected to the inner wall of the workbench 1, the side wall of the workbench 1 is provided with a connecting groove 26, a connecting pipe 25 is connected between the connecting groove 26 and the hollow block 21, a driving block 27 is sealed and slidably connected in the connecting groove 26, the side of the driving block 27 away from the hollow block 21 is in an inclined shape, and a limiting component for limiting the adjusting block 22 is provided in the hollow block 21;

[0037] When the connection frame 8 needs to be tilted, the limiting component can no longer limit the adjusting block 22. At this time, the adjusting block 22 will move downward, and the connection frame 8 in contact with the adjusting block 22 will also rotate downward, allowing the connection frame 8 to tilt, so that the pipeline on the connection frame 8 can be discharged. When the adjusting block 22 moves downward, it will push the gas in the hollow block 21 from the connecting pipe 25 into the connecting groove 26. At this time, the gas will push the driving block 27 to slide outward in the connecting groove 26. When the pipeline discharge is completed and the connection frame 8 needs to be reset, the mounting plate 3 can be driven to push the driving block 27. At this time, the driving block 27 will push the gas in the connecting groove 26 from the connecting pipe 25 into the hollow block 21, and then the adjusting block 22 is moved upward under the action of the gas, thereby pushing the connection frame 8 to rotate upward for reset, and then the connection frame 8 is limited by the limiting component. Through the above mechanism, the connection frame 8 can be automatically tilted and reset to facilitate the discharge of the pipeline.

[0038] The limiting assembly includes a "U"-shaped driving rod 23 which is sealingly and slidingly connected to the side wall of the hollow block 21, and the end of the driving rod 23 away from the hollow block 21 can be pushed by the mounting plate 3. A fixing ring 24 is fixedly connected to the surface of the driving rod 23, and a first spring is fixedly connected between the fixing ring 24 and the side wall of the hollow block 21. When the hollow block 21 needs to move downward, the driving rod 23 can be pushed with the help of the mounting plate 3 so that the driving rod 23 moves away from under the moving rod 12. At this time, the adjusting block 22 will move downward due to gravity, and then in the process of the mounting plate 3 pushing the driving block 27, the mounting plate 3 will move away from the moving rod 12. At this time, the first spring will pull the driving rod 23, and then in the process of the adjusting block 22 rising, when the bottom surface of the adjusting block 22 is higher than the driving rod 23, the driving rod 23 will move to the bottom surface of the adjusting block 22 under the drive of the first spring to limit the adjusting block 22.

[0039] The mounting plate 3 is provided with a clamping mechanism, which includes a fixing rod 11 fixedly connected to the top surface of the mounting plate 3, and a moving rod 12 is sealingly and slidably connected to one end of the fixing rod 11 away from the mounting plate 3, and a second spring (not shown in the figure) is fixedly connected between the top surface of the moving rod 12 and the inner wall of the fixing rod 11, and a clamping block 13 is fixedly connected to the bottom surface of the moving rod 12, and a moving component for driving the moving rod 12 to move is provided on the electric telescopic rod 5; when the present application cuts the pipeline, the moving rod 12 can be driven downward by the moving component, so that the clamping block 13 presses the pipeline to prevent the pipeline from moving when cutting the pipeline, thereby affecting the cutting effect of the pipeline, and after the pipeline is pressed, the blade 7 is used to cut the pipeline.

[0040] The moving assembly includes an extrusion ring 16 fixed to the output end surface of the electric telescopic rod 5, a connecting ring 14 is fixedly connected to the surface of the electric telescopic rod 5, a hollow elastic ring 15 is fixedly connected to the bottom surface of the connecting ring 14, a conduit 17 is connected between the elastic ring 15 and the fixed rod 11, and a first control valve is arranged on the conduit 17;

[0041] When the movable rod 12 needs to move upward, the output end of the electric telescopic rod 5 can be moved upward with the help of the extrusion ring 16 to squeeze the elastic ring 15, so that the gas in the elastic ring 15 enters the fixed rod 11 from the conduit 17. At this time, the gas will push the movable rod 12, allowing the clamping block 13 to clamp the pipeline, thereby achieving the effect of fixing the pipeline. When the output end of the electric telescopic rod 5 moves downward, the first control valve can be closed, so that the fixed rod 11 is in a closed space, so that the movable rod 12 is always in the original position. When the movable rod 12 needs to be reset, the first control valve is opened. At this time, the movable rod 12 will be reset under the pull of the second spring, and the gas in the fixed rod 11 will be pushed into the elastic ring 15.

[0042] The inner wall of the clamp block 13 is fixedly connected with a hollow and elastic arc-shaped piece 18, a through slot 19 is vertically penetrated in the moving rod 12, a second control valve is arranged in the through slot 19, a connecting hole 20 is vertically penetrated in the clamp block 13 and communicated with the through slot 19, and a circular hole is opened on the outer wall of the arc-shaped piece 18 and communicated with the connecting hole 20; since polyethylene pipes have pipes of different sizes during production, the size of the clamp block 13 remains unchanged, and if the outer diameter of the pipe is smaller than the inner diameter of the clamp block 13, the contact surface between the clamp block 13 and the pipe The clamping block 13 in the present application clamps the pipeline, and the arc-shaped piece 18 will contact the pipeline, and then open the second control valve, and then let the extrusion ring 16 continue to squeeze the elastic ring 15, so that the gas in the elastic ring 15 continues to enter the pipeline rod, and then the gas passes through the through groove 19, the connecting hole 20 and the circular groove into the arc-shaped piece 18. At this time, the arc-shaped piece 18 will expand and fit the pipeline, thereby increasing the clamping area of ​​the pipeline to improve the clamping effect of the pipeline, and then close the second control valve.

[0043] Embodiment 2: Figure 6 to Figure 7 As shown, in contrast to Example 1, another implementation of the present invention is as follows: a group of guide grooves 28 are provided on the inner wall of the workbench 1, and a magnetic block 29 is slidably connected to the inner wall of the guide groove 28, and the magnetic block 29 is magnetically attracted to the mounting block 6, and a pipe on one side of the magnetic blocks 29 close to each other is connected to a cleaning plate 30 in contact with the bottom surface of the workbench 1, and an inclined groove 31 is provided on one side of the workbench 1, and a hollow recovery block 32 is provided on the side of the workbench 1 close to the inclined groove 31, and the top end of the recovery block 32 is opened; in the present application, when the pipe is cut, the waste generated during the cutting process will fall onto the bottom surface of the workbench 1, and at this time, when the mounting plate 3 moves, the mounting plate 3 will drive the magnetic block 29 to move, so that the magnetic block 29 drives the cleaning plate 30 to clean the waste on the bottom surface of the workbench 1, and the waste will be pushed to the inclined groove 31 by the cleaning plate 30, and then slide from the inclined groove 31 to the recovery block 32 to be recovered, thereby achieving the effect of cleaning and recycling the waste.

[0044] like Figure 8 As shown, the production process of ultra-high molecular polyethylene pipes, which uses the above-mentioned production equipment for high molecular polyethylene pipes, includes the following steps:

[0045] S1: The raw material is a polyethylene resin with a molecular weight of more than 2 million, and then the polyethylene resin is transported to the hopper of the twin-screw extruder, and the polyethylene resin enters the extruder;

[0046] S2: The extruder melts the polyethylene resin by heating the screw. The screw of the extruder needs to work at a temperature between 200-260°C. The molten polyethylene flows along the mold under the push of the screw and is formed;

[0047] S3: The formed high molecular polyethylene pipe needs to be cooled in a water tank. The cooled pipe will be pulled by a traction machine to stabilize the size of the pipe and avoid deformation.

[0048] S4: After cooling and pulling, the pipe enters the cutting process, the polyethylene pipe is placed on the connection frame 8 to contact the roller 10, and the driving wheel 4 is driven to rotate by the first motor, thereby driving the mounting plate 3 to move, and the mounting plate 3 moves to a suitable position;

[0049] S5: Start the electric telescopic rod 5, let the output end push the blade 7 to move downward, and at the same time, the second motor drives the blade 7 to rotate, so that the blade 7 completes the cutting of the pipe, and then continues to move the mounting plate 3 to the next position, and continues to use the blade 7 to cut the pipe;

[0050] S6: After the pipe cutting is completed, the connection frame 8 can be tilted by means of a tilting mechanism, so that the pipe slides off the connection frame 8 under the action of the roller 10, thereby realizing the discharge work.

[0051] Working principle: When the polyethylene pipe is cut, the polyethylene pipe can be placed on the connecting frame 8, and the polyethylene pipe will contact the roller 10. Then, the first motor drives the driving wheel 4 to rotate, thereby driving the mounting plate 3 to move. After the mounting plate 3 moves to a suitable position, the pipe can be cut to meet the needs of cutting the pipe into sections of different standard lengths. Then, the electric telescopic rod 5 can be started to allow the output end to push the blade 7 to move downward, and at the same time, the second motor drives the blade 7 to rotate, so that the blade 7 completes the cutting of the pipe. Then, the mounting plate 3 continues to move to the next position, and the blade 7 continues to be used to cut the pipe. After the pipe cutting is completed, the connecting frame 8 can be tilted with the help of the tilting mechanism, so that the pipe slides off the connecting frame 8 under the force of the roller 10, thereby realizing the discharge work;

[0052] When the connection frame 8 needs to be tilted, the limiting component can stop limiting the adjusting block 22. At this time, the adjusting block 22 will move downward, and the connection frame 8 in contact with the adjusting block 22 will also rotate downward, allowing the connecting frame 8 to tilt, so that the pipeline on the connecting frame 8 can be discharged. When the adjusting block 22 moves downward, it will push the gas in the hollow block 21 from the connecting pipe 25 into the connecting groove 26. At this time, the gas will push the driving block 27 to slide outward in the connecting groove 26. When the pipeline discharge is completed and the connection frame 8 needs to be reset, the mounting plate 3 can be driven to push the driving block 27. At this time, the driving block 27 will push the gas in the connecting groove 26 from the connecting pipe 25 into the hollow block 21, and then let the adjusting block 22 move upward under the action of the gas, thereby pushing The connecting frame 8 is rotated upward to reset, and then the connecting frame 8 is limited by the limiting assembly. The connecting frame 8 can be automatically tilted and reset by the above mechanism to facilitate the discharge of the pipeline; when the hollow block 21 needs to move downward, the driving rod 23 can be pushed by the mounting plate 3 so that the driving rod 23 is moved away from under the moving rod 12. At this time, the adjusting block 22 will move downward due to gravity, and then in the process of the mounting plate 3 pushing the driving block 27, the mounting plate 3 will be away from the moving rod 12. At this time, the first spring will pull the driving rod 23. Later, in the process of the adjusting block 22 rising, when the bottom surface of the adjusting block 22 is higher than the driving rod 23, the driving rod 23 will move to the bottom surface of the adjusting block 22 under the drive of the first spring to limit the adjusting block 22.

[0053] When the present application is cutting the pipeline, the moving rod 12 can be driven downward by the moving assembly, so that the clamping block 13 can press the pipeline to prevent the pipeline from moving when the pipeline is cut, which affects the cutting effect of the pipeline. After the pipeline is pressed, the blade 7 is used to cut the pipeline; when the present application needs to move the moving rod 12 upward, the output end of the electric telescopic rod 5 can be moved upward to allow the extrusion ring 16 to squeeze the elastic ring 15, so that the gas in the elastic ring 15 enters the fixed rod 11 from the conduit 17. At this time, the gas will push the moving rod 12, allowing the clamping block 13 to clamp the pipeline, thereby achieving the effect of fixing the pipeline. When the output end of the electric telescopic rod 5 moves downward, the first control valve can be closed, so that the fixed rod 11 is in a closed space, so that the moving rod 12 is always in the original position. When the moving rod 12 needs to be reset, the first control valve is opened. At this time, the moving rod 12 will be reset under the pull of the second spring, and the gas in the fixed rod 11 will be pushed into the elastic ring 15.

[0054] Since polyethylene pipes have different sizes during production, the size of the clamp block 13 remains unchanged. If the outer diameter of the pipe is smaller than the inner diameter clamped by the clamp block 13, the contact surface between the clamp block 13 and the pipe is limited, which will affect the clamping effect of the pipe. When the clamp block 13 in the present application clamps the pipe, the arcuate sheet 18 will contact the pipe, and then the second control valve will be opened, and then the extrusion ring 16 will continue to squeeze the elastic ring 15, so that the gas in the elastic ring 15 continues to enter the pipe rod, and then the gas passes through the through groove 19, the connecting hole 20 and the circular groove into the arcuate sheet 18. At this time, the arcuate sheet 18 will expand and fit the pipe, thereby increasing the clamping area of ​​the pipe to improve the clamping effect of the pipe, and then the second control valve will be closed.
