Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene pipe fitting processing, in particular to a trimming device for polyethylene pipe fitting processing. Background Technique

[0002] A polyethylene composite pipe refers to a pipe made by using two different density polyethylene resins, plasticizing and melting them respectively with two extruders at the same time, and then simultaneously extruding the molten materials into a mold capable of forming a composite pipe. At present, after the polyethylene composite pipe is produced, a grinding device is required to grind and deburr it.

[0003] For example, patent CN210731981U proposes a trimming device for polyethylene composite pipe processing. The polyethylene composite pipe is placed on the top surface of the supporting device, and then the clamping plate is pulled by the handle under the action of the spring to fix the end of the polyethylene composite pipe. At this time, the first servo motor works to drive the disc to rotate. At this time, the polyethylene composite pipe located on one side of the disc will rotate accordingly. Then the second servo motor works to drive the grinding disc to rotate. At this time, the second threaded rod is rotated by the handwheel. At this time, the T-shaped slider screwed on the outer wall of the second threaded rod will move to one side and approach the end of the polyethylene composite pipe for grinding and trimming. In this way, the end of the polyethylene composite pipe can be made smoother and flatter, so as to facilitate connection and make installation more convenient.

[0004] The deficiencies in the above solution are as follows: After clamping the pipe fitting in the solution, one end is ground and trimmed, while the other end needs to be disassembled and reinstalled before continuing to trim, which is rather inconvenient. At the same time, only the two ends can be trimmed, and the outer surface cannot be ground. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a trimming device for polyethylene pipe fitting processing to solve the problems put forward in the above background technique. The structure of the utility model is novel. The pipe body is clamped and fixed by the clamping plates in two collars, and the clamping position can be adjusted according to the length of the pipe body. One end of the pipe body corresponds to the grinding disc, and the outer surface corresponds to the grinding roller. The trimming of the port and the outer surface can be realized simultaneously. At the same time, the slide rail can be flipped and the first electric push rod can be advanced to quickly switch the two ends of the pipe body for grinding, saving the replacement time.

[0006] To achieve the above object, the utility model is realized through the following technical solutions: A trimming device for processing polyethylene pipe fittings, including a base, on the top of the base, a slide rail is rotatably installed through a bearing, and two sliding seats are symmetrically and slidably installed on the slide rail. A hollow plate is fixed on the top of the sliding seat, and a collar is rotatably installed on the surface of the hollow plate through a bearing. A pipe body is installed between the two groups of collars. A grinding disc driven by a motor is installed at one end of the base, and a moving component is arranged on one side of the base where the pipe body is located. The moving component includes a connecting frame, on the surface of the connecting frame, a grinding roller driven by a motor is installed, and the grinding roller is in contact with the surface of the pipe body. Two groups of clamping plates are arranged inside the collar, and a second electric push rod is fixed at a position corresponding to the clamping plate on the outer side of the collar.

[0007] Further, a toothed ring is sleeved on the outer ring of the collar on one side of the slide rail. A first motor is fixed on the top of the hollow plate corresponding to the toothed ring, and a gear is fixed at the output end of the first motor. The gear is meshed with the toothed ring.

[0008] Further, two groups of first electric push rods are fixed on both sides of the slide rail, and the extending ends of the first electric push rods are respectively fixedly connected with the two end sliding seats.

[0009] Further, the moving component further includes a screw rod. The screw rod is rotatably installed inside the connecting frame through a bearing, and a second motor is fixed at the outer end of the connecting frame. The output end of the second motor is fixedly connected with the screw rod. The grinding roller is threadedly sleeved on the screw rod through a mounting seat.

[0010] Further, a plug board is slidably inserted into one end of the sliding seat facing the connecting frame, and the top of the plug board slides along the bottom of the connecting frame.

[0011] Further, a moving notch is opened at the top of the collar, and a connecting plate is fixed at the extending end of the second electric push rod. The connecting plate passes through the moving notch.

[0012] Further, an arc-shaped frame is slidably connected at a position corresponding to the connecting plate on the upper surface of the connecting frame. One end of the connecting plate slides along the arc-shaped frame. The arc-shaped frame and the center of the collar are on the same axis.

[0013] Further, a third electric push rod is fixed at the outer end of the arc-shaped frame. A jack is opened at one end of the connecting plate inserted into the arc-shaped frame, and the extending end of the third electric push rod can be inserted into the jack.

[0014] The beneficial effects of the utility model:

[0015] 1. In the present utility model, the extended end of the third electric push rod is inserted into the jack. Then, when the second electric push rod adjusts the position of the clamping plate according to the size of the pipe body, the connecting plate will drive the moving component to move synchronously, keeping the grinding roller in contact with the surface of the pipe body, thus saving the time for subsequent adjustment. When rotating, the extended end of the third electric push rod is retracted, the collar rotates, and the connecting plate can rotate along the arc frame without causing rotational interference. At the same time, when adjusting the distance between the two collars along the slide rail, the arc frame can slide along the top of the connecting frame.

[0016] 2. In the present utility model, the second motor drives the screw to rotate, and the mounting seat of the grinding roller cooperates with the screw to drive the grinding roller to translate for grinding the surface of the pipe body. By connecting the insertion plate with the connecting frame, the position of the connecting frame can be adjusted. And when the collar moves, the insertion plate can also slide along the bottom of the connecting frame to maintain the connection with the connecting frame.

[0017] 3.

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation mode.

[0026] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a trimming device for polyethylene pipe fittings, including a base 1. The top of the base 1 is rotatably installed with a slide rail 2 through a bearing, and two slide blocks 21 are symmetrically and slidably installed on the slide rail 2. The top of the slide block 21 is fixed with a hollow plate 22, and the surface of the hollow plate 22 is rotatably installed with a sleeve 23 through a bearing. A pipe body 3 is installed between the two groups of sleeves 23. One end of the base 1 is installed with a motor-driven grinding disc 11, and a moving component 4 is arranged on one side of the base 1 where the pipe body 3 is located. The moving component 4 includes a connecting frame 41. The surface of the connecting frame 41 is installed with a motor-driven grinding roller 43, and the grinding roller 43 is in contact with the surface of the pipe body 3. Two groups of clamping plates 29 are arranged inside the sleeve 23, and a second electric push rod 210 is fixed at a position corresponding to the clamping plate 29 on the outside of the sleeve 23. The extending end of the second electric push rod 210 is fixedly connected with the clamping plate 29. When using the device, adjust the positions of the two groups of hollow plates 22 and sleeves 23 along the slide rail 2 according to the length of the pipe body 3. Insert both ends of the pipe body 3 into the inside of the sleeve 23 and pass through the hollow plate 22. The clamping plate 29 clamps and fixes the pipe body 3. Make one end of the pipe body 3 contact with the grinding disc 11, and grind the surface and both ends of the pipe body 3 through the grinding disc 11 and the grinding roller 43 to improve the grinding efficiency.

[0027] In this embodiment, an outer ring of a collar 23 on one side of the slide rail 2 is sleeved with a toothed ring 26. A first motor 24 is fixed to the top of the hollow plate 22 corresponding to the toothed ring 26, and a gear 25 is fixed to an output end of the first motor 24. The gear 25 is meshed with the toothed ring 26. Two groups of first electric push rods 27 are fixed to both sides of the slide rail 2, and the extended ends of the first electric push rods 27 are respectively fixed to the two end slides 21. The first motor 24 drives the gear 25 to rotate and mesh with the toothed ring 26, thereby driving the collar 23 to rotate, so that the pipe body 3 rotates and contacts the grinding disc 11 and the grinding roller 43. The positions of the two collars 23 can be adjusted by the first electric push rods 27. At the same time, when the clamping plate 29 in one collar 23 is fixed and the clamping plate 29 in the other collar 23 is released from clamping, the pipe body 3 is pushed by the first electric push rod 27 to contact the grinding disc 11 for edge trimming and grinding.

[0028] In this embodiment, the moving assembly 4 further includes a screw rod 45. The screw rod 45 is rotatably installed in the connecting frame 41 through a bearing, and a second motor 46 is fixed to the outer end of the connecting frame 41. The output end of the second motor 46 is fixed to the screw rod 45. The grinding roller 43 is threadedly sleeved on the screw rod 45 through a mounting seat. One end of the slide 21 facing the connecting frame 41 is slidably inserted with a plug board 42, and the top of the plug board 42 slides along the bottom of the connecting frame 41. The second motor 46 is started to drive the screw rod 45 to rotate, and the mounting seat of the grinding roller 43 cooperates with the screw rod 45 to drive the grinding roller 43 to translate, so as to grind the surface of the pipe body 3. By connecting the plug board 42 with the connecting frame 41, the position of the connecting frame 41 can be adjusted. When the collar 23 moves, the plug board 42 can also slide along the bottom of the connecting frame 41 to maintain the connection with the connecting frame 41. This sliding method is a simple sliding frame buckling method.

[0029] In this embodiment, a moving notch 28 is formed at the top of the collar 23, and a connecting plate 211 is fixed to the extending end of the second electric push rod 210. The connecting plate 211 passes through the moving notch 28. A circular arc frame 44 is slidably connected to the position corresponding to the connecting plate 211 on the upper surface of the upper end of the connecting frame 41. One end of the connecting plate 211 slides along the circular arc frame 44. The circular arc frame 44 and the center of the collar 23 are on the same axis. A third electric push rod 212 is fixed to the outer end of the circular arc frame 44. A jack 213 is formed at one end of the connecting plate 211 inserted into the circular arc frame 44, and the extending end of the third electric push rod 212 can be inserted into the jack 213. In the initial state, the outer end of the connecting plate 211 is inserted into the circular arc frame 44, and the extending end of the third electric push rod 212 is inserted into the jack 213. When the second electric push rod 210 adjusts the position of the clamping plate 29 according to the size of the pipe body 3, the connecting plate 211 will drive the moving assembly 4 to move synchronously, keeping the grinding roller 43 in contact with the surface of the pipe body 3, thus saving the time for subsequent adjustment. During rotation, the extending end of the third electric push rod 212 is retracted, the collar 23 rotates, and the connecting plate can rotate along the circular arc frame 44 without causing rotational interference. At the same time, when adjusting the distance between the two collars 23 along the slide rail 2, the circular arc frame 44 can slide along the top of the connecting frame 41.

[0030] When using the device, adjust the positions of the two groups of hollow plates 22 and collars 23 along the slide rail 2 according to the length of the pipe body 3. Insert both ends of the pipe body 3 into the collars 23 and pass through the hollow plates 22. The clamping plate 29 clamps and fixes the pipe body 3. Contact one end of the pipe body 3 with the grinding disc 11. When the extending end of the third electric push rod 212 is inserted into the jack 213, and then when the second electric push rod 210 adjusts the position of the clamping plate 29 according to the size of the pipe body 3, the connecting plate 211 will drive the moving assembly 4 to move synchronously, keeping the grinding roller 43 in contact with the surface of the pipe body 3, thus saving the time for subsequent adjustment. During rotation, the extending end of the third electric push rod 212 is retracted, the collar 23 rotates, and the connecting plate can rotate along the circular arc frame 44 without causing rotational interference. At the same time, when adjusting the distance between the two collars 23 along the slide rail 2, the circular arc frame 44 can slide along the top of the connecting frame 41. Turn on the second motor 46 to drive the screw 45 to rotate. The mounting seat of the grinding roller 43 cooperates with the screw 45 to drive the grinding roller 43 to translate and grind the surface of the pipe body 3. By connecting the insertion plate 42 with the connecting frame 41, the position of the connecting frame 41 can be adjusted, and when the collar 23 moves, the insertion plate 42 can also slide along the bottom of the connecting frame 41 to maintain the connection with the connecting frame 41. The surface and both ends of the pipe body 3 are ground by the grinding disc 11 and the grinding roller 43, improving the grinding efficiency.
