Description

Technical Field

[0001] The invention belongs to the technical field of PE pipe production and processing, and specifically relates to a PE pipe production and processing device and a processing method. Background Art

[0002] PE pipes, also known as polyethylene pipes, are water supply pipes used inside buildings. They are cost-effective and therefore widely used. After the production of some PE pipes, burrs or unevenness easily appear on the inner wall, so grinding equipment is needed to grind the inner wall of the PE pipe.

[0003] A patent with publication number CN215510515U discloses a small-diameter PE pipe attached inner wall polishing device, including a base. The pipe is first clamped and fixed by a fixing mechanism, and then the height of an adjustable grinding head is adjusted by two pairs of linear guides to meet the inner wall polishing requirements of pipes with different wall thicknesses. The adjustable grinding head is then driven to move in the pipe by the linear guide to meet the inner wall polishing requirements of pipes of different lengths. The adjustable grinding head can adjust the position of the arc-shaped grinding sheet for pipes with different inner diameters so that the arc-shaped grinding sheet fits the inner wall of the pipe, and then the arc-shaped grinding sheet can be driven by a motor to rotate to polish the inner wall of the pipe.

[0004] There are still some problems in the actual application of the above scheme. In the process of using the above-mentioned polishing device to polish the inner wall of the PE pipe, the inner wall of the PE pipe is polished by multiple arc-shaped polishing sheets. However, since the polishing process generates heat, the temperature of the inner wall of the PE pipe increases. This temperature increase may cause the polished chips or cutting residues to soften over a period of time and adhere to the inner wall of the pipe, thereby increasing the difficulty of removal. It may even be necessary to perform secondary polishing on these chips or cutting residues adhered to the inner wall of the PE pipe, thereby affecting the production efficiency of PE pipe polishing.

[0050] 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.

[0051] Embodiment 1

[0052] like Figures 1 to 11As shown, a PE pipe production and processing device and processing method described in an embodiment of the present invention include a workbench 1, a guide rail 2 is provided on the upper surface of the workbench 1, a first motor 21 is slidably provided on the guide rail 2, a mold 22 is fixedly connected to the output end of the first motor 21, two auxiliary rollers 4 are rotatably provided in the middle of the upper surface of the workbench 1, a second motor 28 is provided at one end of one of the auxiliary rollers 4, a first strip steel 29 is transmission-connected to the output end of the second motor 28, and the other end of the first strip steel 29 is transmission-connected to the auxiliary roller 4, a support column 5 is provided on one side of one of the auxiliary rollers 4, a second hydraulic cylinder 51 is fixedly connected to the top of the support column 5, and a connecting block 5 is fixedly connected to the output end of the second hydraulic cylinder 51. 3. Two auxiliary rings 52 are fixedly connected to the lower surface of the connecting block 53; a cleaning assembly is provided at the output end of the first motor 21, and the cleaning assembly includes a cleaning roller 23 fixedly connected to the output end of the first motor 21; a plurality of brushes are provided on the circumferential surface of the cleaning roller 23; a water storage tank 24 is provided at the side of the auxiliary roller 4 away from the first motor 21, and the water storage tank 24 has a built-in pressure pump; a nozzle 25 is provided at one side of the water storage tank 24, and the nozzle 25 is designed as a "nozzle" type; and a drainage groove 27 is provided on the upper surface of the workbench 1, and there are two drainage grooves 27, which are located at both ends of the two auxiliary rollers 4; and a collecting frame 7 is clamped on one side of the workbench 1, and the collecting frame 7 is located directly below the outlet of the drainage groove 27.

[0053] Specifically, in the process of using the existing polishing device to polish the inner wall of the PE pipe, the inner wall of the PE pipe is polished by multiple arc-shaped polishing sheets. However, since the polishing process generates heat, the temperature of the inner wall of the PE pipe increases. This temperature increase may cause the polished debris or cutting residues to soften over a period of time and adhere to the inner wall of the pipe, thereby increasing the difficulty of removal. It may even be necessary to perform secondary polishing on the debris or cutting residues adhered to the inner wall of the PE pipe, thereby reducing the polishing efficiency of the PE pipe polishing device.

[0054] Therefore, the present invention improves the grinding efficiency of the grinding device by timely cleaning the PE pipe after grinding. First, the polyethylene pipe 11 to be ground is placed between the two auxiliary rollers 4, and then the second hydraulic cylinder 51 is started. The second hydraulic cylinder 51 will drive the connecting block 53 fixedly connected to its output end to move downward. The downward movement of the connecting block 53 will drive the two auxiliary rings 52 fixed to the lower surface of the connecting block 53. The cross-sections of the two auxiliary rings 52 are arc-shaped. Then, the polyethylene pipe 11 placed between the two auxiliary rollers 4 will be limited to prevent it from being displaced during the grinding process. After the polyethylene pipe 11 is limited, the first motor 21 is started at this time. The first motor 21 will drive the grinding of its output end. The tool 22 rotates, and then the first motor 21 is driven to move toward the polyethylene tube 11 by starting the guide rail 2. When it moves to just abut against the end of the polyethylene tube 11, the second motor 28 is started. The start of the second motor 28 drives one of the auxiliary rollers 4 to rotate, thereby driving the polyethylene tube 11 to rotate slowly. The rotation direction is opposite to that of the first motor 21. Then, when the grinding tool 22 is grinding and polishing the inner wall of the polyethylene tube 11, the reverse rotation of one of the auxiliary rollers 4 and the rotation direction of the grinding tool 22 can form an interactive force on the polyethylene tube 11, so that the grinding tool 22 can better grind the inner wall of the polyethylene tube 11 during grinding, thereby improving the grinding effect.

[0055] At the same time, when the mold 22 starts to grind, the pressure pump in the water tank 24 is started, and the water in the water tank 24 is pressurized and sprayed into the polyethylene tube 11 along the nozzle 25, and then the mold moves forward for grinding. The sprayed water mist can cool the polyethylene tube 11, and also protect the mold 22 to a certain extent, extending the service life of the mold 22. After the mold 22 enters the polyethylene tube 11, the cleaning roller 23 located behind the mold 22 will also enter the polyethylene tube 11, so as to clean the debris or softened debris just formed by grinding until the grinding of the mold 22 is completed. Move out of the polyethylene tube 11, and then the cleaning roller 23 will also move out of the polyethylene tube 11 with the debris, and then when the first motor 21 stops and resets, the cleaning roller 23 will clean the inner wall of the polyethylene tube 11 again to further prevent the debris from remaining on the inner wall of the polyethylene tube 11, and the sprayed water gathered during the working process will carry part of the debris out of the polyethylene tube 11, and then flow into the drainage groove 27, and then enter the collection frame 7 along the drainage groove 27, thereby completing the timely cleaning of the polyethylene tube 11, and achieving the effect of improving the production efficiency of the polyethylene tube 11;

[0056] The problem that the temperature of the polyethylene tube 11 rises during the grinding process, and then the debris generated by the grinding softens due to the high temperature and adheres to the inner wall of the polyethylene tube 11, thereby forming secondary burrs is solved.

[0057] like Fig. 9 As shown, in this embodiment, a plurality of first grooves 54 are formed on the lower surface of each auxiliary ring 52 , and a rotating wheel 55 is rotatably disposed in each first groove 54 .

[0058] Specifically, in the process of using the auxiliary ring 52, in order to enable the auxiliary ring 52 to limit the polyethylene tube 11 while not affecting the slow rotation of the polyethylene tube 11, thereby achieving a better grinding effect on the inner wall of the polyethylene tube 11, a plurality of first grooves 54 are provided on the lower surface of each auxiliary ring 52, and then a rotating wheel 55 is rotatably provided in each first groove 54, thereby achieving the effect of not affecting the rotation of the polyethylene tube 11 while limiting it.

[0059] like Figure 7 As shown, in this embodiment, slots 71 are provided on both sides of the inner wall of the collecting frame 7, and an insertion rod 73 is inserted into each slot 71. The bottom ends of the two insertion rods 73 are fixedly connected to the same filter screen 72.

[0060] Specifically, after the water carrying debris enters the drainage trough 27, since this part of the water does not have serious pollutants, it is only necessary to filter the debris and recycle the water for secondary use. By inserting the filter screen 72 in the collection frame 7, the water can be recycled, thereby achieving the effect of saving resources and rationally utilizing resources.

[0061] like Figure 3 As shown, in this embodiment, a sealing cover 26 is provided on the upper surface of the water storage tank 24 , and the sealing cover 26 is used to increase the amount of water stored in the water storage tank 24 .

[0062] Specifically, after the water tank 24 has been used for a certain period of time, the water level in the water tank 24 is insufficient, and the pressure pump cannot spray out a sufficiently strong water mist. Therefore, a sealing cover 26 is provided at the top of the water tank 24. When water needs to be replenished, the sealing cover 26 can be opened, and then water can be poured into the water tank 24 to complete the timely replenishment of the water tank 24.

[0063] Embodiment 2

[0064] like Figures 2 to 11 As shown, compared with Example 1, another embodiment of the present invention is: a first hydraulic cylinder 12 is arranged between the two auxiliary rollers 4, and a push block 13 is fixedly connected to the output end of the first hydraulic cylinder 12; two bottom blocks 62 are arranged on one side of one of the auxiliary rollers 4, and an inclined plate 613 is fixedly connected between the two bottom blocks 62, and the length of the inclined plate 613 is the same as the length of the polyethylene tube 11.

[0065] Specifically, after the polyethylene pipe 11 is polished and the first motor 21 is reset, the first hydraulic cylinder 12 is started, and the output end of the first hydraulic cylinder 12 is fixedly connected with an arc-shaped push block 13. Then the arc-shaped push block 13 will push the polyethylene pipe 11 to tilt toward the inclined plate 613, and then pass through the limit of the two bottom blocks 62, slide out along the inclined plate 613, and be collected uniformly.

[0066] like Fig.10 and Fig.11 As shown, in this embodiment, the upper surfaces of the two bottom blocks 62 are fixedly connected to the same blanking frame 6, and a first cavity 61 is provided inside the blanking frame 6. A second slot body 63 is provided on the side of the two bottom blocks 62 close to each other, and a third slot body 64 is provided on the inner wall of each second slot body 63. A fixing rod 69 is fixedly connected to each third slot body 64. A compression spring 610 is sleeved on the circumferential surface of each fixing rod 69, and a sliding column 611 is sleeved on one end of each fixing rod 69. Each sliding column 611 is fixed to one end of the compression spring 610, and a connecting rod 612 is fixedly connected to the surface of each sliding column 611. The ends of the two connecting rods 612 away from the sliding column 611 are fixedly connected to the same guide plate 66.

[0067] Specifically, in the process of the polyethylene tube 11 being lifted up and sliding down along the inclined plate 613, the impact force of the polyethylene tube 11 itself falling will push the sliding column 611 in the third groove body 64 of each bottom block 62, thereby pushing the sliding column 611 to slide upward along the fixed rod 69. The fixed rod 69 and the third groove body 64 are both arc-shaped, so the trajectory of the sliding column 611 is also arc-shaped. The sliding of the sliding column 611 will also drive the connecting rod 612 fixed to its surface. The rotation arc of the connecting rod 612 is opposite to the movement arc of the sliding column 611. After the connecting rod 612 rotates, it will pull it away from the guide plate 66 at one end of the sliding column 611. The rotation of the guide plate 66 will guide the unpolished polyethylene tube 11 in the upper unloading frame 6 to between the two auxiliary rollers 4, thereby realizing automatic loading and achieving the effect of improving the grinding efficiency of the polyethylene tube 11.

[0068] like Fig.11 As shown, in this embodiment, a rotating column 68 is rotatably provided on one side of the guide plate 66, and the rotating column 68 is rotatably provided between the two bottom blocks 62. A partition plate 65 is fixedly connected to one side of the guide plate 66 corresponding to the rotating column 68, and the cross section of the partition plate 65 is arc-shaped.

[0069] Specifically, when the guide plate 66 rotates, in order to prevent other polyethylene tubes 11 in the discharge frame 6 from rolling down, an arc-shaped partition 65 is fixedly connected to one side of the guide plate 66. The rotation of the guide plate 66 will drive the partition 65 to rotate. After the partition 65 rotates, it will block the discharge port of the discharge frame 6, so that only one polyethylene tube 11 can roll out at a time.

[0070] like Fig.11 As shown, a plurality of speed reduction strips 67 are fixedly connected to the surface of the guide plate 66 of this embodiment, and the material of the speed reduction strips 67 is rubber.

[0071] Specifically, during the process of the guide plate 66 guiding the polyethylene tube 11 to slide down, a plurality of rubber speed reduction strips 67 are fixedly connected to the guide plate 66 , so that the polyethylene tube 11 falls slowly during the process and can fall steadily between the two auxiliary rollers 4 , thereby achieving the effect of preventing the polyethylene tube 11 from rolling out from between the two auxiliary rollers 4 .

[0072] like Figure 2 As shown, a control console 3 is disposed on the upper surface of the workbench 1 in this embodiment, and the control console 3 is used for controlling the first motor 21 and the first hydraulic cylinder 12 .

[0073] Specifically, a PE pipe production and processing method comprises the following steps:

[0074] Step 1: Raw material preparation, select high-quality polyethylene resin as raw material, and then mix and process it;

[0075] Step 2: Extrusion molding, the mixed and processed polyethylene resin is fed into an extruder, and then the heated polyethylene resin is fed into a metal mold through the extruder, extruded into a tube through a specific shape of the mold, and finally cooled by cooling water or air to solidify it into shape;

[0076] Step 3: Pipe cutting, transferring the extruded long pipe to an automatic or semi-automatic cutting device, and then cutting it into polyethylene pipes 11 of corresponding lengths;

[0077] Step 4: Grinding the inner wall. Place the cut polyethylene tube 11 between the two auxiliary rollers 4 on the upper surface of the workbench 1, and then start the second hydraulic cylinder 51. The output end of the second hydraulic cylinder 51 will drive the auxiliary ring 52 to move downward. The auxiliary ring 52 will limit the polyethylene tube 11. Then start the first motor 21. The first motor 21 will drive the grinding tool 22 at its output end to rotate. Then start the electric guide rail 2 to drive the first motor 21 and the grinding tool 22 at its output end to move toward the direction of the polyethylene tube 11, and then insert it into the polyethylene tube 11, so as to grind and eliminate the burrs in the polyethylene tube 11.

[0078] Step 5: Packaging and transportation: the polished polyethylene pipes 11 are collected and packaged, and then shipped to customers.

[0079] Working principle: first, place the polyethylene tube 11 to be polished between the two auxiliary rollers 4, and then start the second hydraulic cylinder 51. The second hydraulic cylinder 51 will drive the connecting block 53 fixedly connected to its output end to move downward. The downward movement of the connecting block 53 will drive the two auxiliary rings 52 fixed to the lower surface of the connecting block 53. The cross-sections of the two auxiliary rings 52 are arc-shaped, and a plurality of first grooves 54 are provided on the lower surface of each auxiliary ring 52. Then, a rotating wheel 55 is rotatably provided in each first groove 54, so as to achieve the effect of not affecting the rotation of the polyethylene tube 11 while limiting it. After the limiting of the polyethylene tube 11 is completed, the first motor 21 is started at this time, and the first motor 21 will drive its output The grinding tool 22 at the end rotates, and then the first motor 21 is driven to move toward the polyethylene tube 11 by starting the guide rail 2. When it moves to just abut against the end of the polyethylene tube 11, the second motor 28 is started. The start of the second motor 28 will drive one of the auxiliary rollers 4 to rotate, thereby driving the polyethylene tube 11 to rotate slowly. The rotation direction is opposite to the rotation direction of the first motor 21. Then, when the grinding tool 22 is grinding and polishing the inner wall of the polyethylene tube 11, the reverse rotation of one of the auxiliary rollers 4 and the rotation direction of the grinding tool 22 can form an interactive force on the polyethylene tube 11, so that the grinding tool 22 can better grind the inner wall of the polyethylene tube 11 during grinding, thereby improving the grinding effect;

[0080] At the same time, when the mold 22 starts to grind, the pressure pump in the water tank 24 is started, and the water in the water tank 24 is pressurized and sprayed into the polyethylene tube 11 along the nozzle 25, and then the mold moves forward for grinding. The sprayed water mist can cool the polyethylene tube 11, and also protect the mold 22 to a certain extent, extending the service life of the mold 22. After the mold 22 enters the polyethylene tube 11, the cleaning roller 23 located behind the mold 22 will also enter the polyethylene tube 11, so as to clean the debris or softened debris just formed by grinding, until the mold 22 is polished and moved out of the polyethylene tube 11, and then the cleaning roller 23 will also move out of the polyethylene tube 11 with the debris, and then in the process of the first motor 21 stopping and resetting, the cleaning roller 2 3 will also clean the inner wall of the polyethylene tube 11 again to further prevent debris from remaining on the inner wall of the polyethylene tube 11, and the water gathered by the spray during the working process will carry part of the debris out of the polyethylene tube 11, and then flow into the drainage groove 27, and then enter the collection frame 7 along the drainage groove 27. After the water carries the debris into the drainage groove 27, since this part of the water does not have very serious pollutants, it is only necessary to filter the debris and recycle the water to achieve secondary utilization. By plugging the filter 72 in the collection frame 7, the water is recycled and utilized, achieving the effect of saving resources and rationally utilizing resources. Finally, the polyethylene tube 11 is cleaned in time to achieve the effect of improving the production efficiency of the polyethylene tube 11.

[0081] After the polyethylene tube 11 is polished and the first motor 21 is reset, the first hydraulic cylinder 12 is started, and the output end of the first hydraulic cylinder 12 is fixedly connected with an arc-shaped push block 13, and then the arc-shaped push block 13 pushes the polyethylene tube 11 to tilt toward the inclined plate 613, and then passes through the limit of the two bottom blocks 62, slides out along the inclined plate 613, and is uniformly collected;

[0082] When the polyethylene tube 11 is lifted up and slides down along the inclined plate 613, the impact force of the polyethylene tube 11 itself will push the sliding column 611 in the third groove 64 of each bottom block 62, thereby pushing the sliding column 611 to slide upward along the fixed rod 69. The fixed rod 69 and the third groove 64 are both arc-shaped, so the trajectory of the sliding column 611 is also arc-shaped. When the sliding column 611 slides, it will drive the connecting rod 612 fixed to its surface. The arc of rotation of the connecting rod 612 is opposite to the arc of movement of the sliding column 611. After the connecting rod 612 rotates, it will pull the guide rod 612 away from one end of the sliding column 611. The guide plate 66, the rotation of the guide plate 66 will guide the unpolished polyethylene tube 11 in the upper unloading frame 6 to between the two auxiliary rollers 4, thereby realizing automatic loading, and achieving the effect of improving the grinding efficiency of the polyethylene tube 11. When the guide plate 66 rotates, in order to prevent other polyethylene tubes 11 in the unloading frame 6 from rolling down, an arc-shaped partition 65 is fixedly connected to one side of the guide plate 66. The rotation of the guide plate 66 will drive the partition 65 to rotate. After the partition 65 rotates, it will block the discharge port of the unloading frame 6, so that only one polyethylene tube 11 can roll out at a time.
