Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing technology, specifically to a rapid cutting and cleaning device for corrugated pipes. Background Technology

[0002] A bellows is a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows require cutting and cleaning during production to facilitate their use after leaving the factory.

[0003] In the prior art, a utility model patent with publication number CN214517862U and titled "A Corrugated Pipe Cutting Device" includes a base frame. The top of the base frame is fitted with a partition to form an installation chamber. A transmission device is installed inside the installation chamber. Two mounting plates are mounted on the transmission device. Brushes are mounted on the surfaces of the mounting plates. A support filter is mounted on the top of the installation chamber. A set of support plates is symmetrically arranged at the center of the surface of the support filter. Sliding grooves are formed on the inner sides of each support plate. A set of placement plates is symmetrically arranged in the middle of the set of support plates. The bottom of the placement plate has a through opening, and a threaded rod is installed within the opening. Both ends of the threaded rod extend into the sliding groove and are slidably connected to it. Nuts are mounted on the outer side of the front support plate. This corrugated pipe cutting device, by incorporating placement plates, support plates, threaded rods, brushes, and support filters, has the advantages of improved safety and reduced production costs.

[0004] The equipment of this patent can quickly clean up the dust generated during the corrugated pipe cutting process; however, the equipment of this patent still has the following technical defects during use: (1) When cutting the corrugated pipe, the equipment of this patent needs to first mark the corrugated pipe to determine the cutting position, then clamp and fix the outer wall of the corrugated pipe, and then repeatedly align the cutting machine body with the marked position of the corrugated pipe. Only after alignment can cutting be carried out. This operation is not only time-consuming, but also prone to deviation of the cutting position due to the staff's lack of careful observation, which can reduce the overall cutting accuracy of the equipment; (2) After the corrugated pipe is cut, waste will be left at the pipe opening. Although the equipment of this patent can clean up the waste generated during the cutting process, some debris will still adhere to the inner wall of the corrugated pipe and is not easy to clean. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid cutting and cleaning device for bellows.

[0006] The technical problem solved by this invention is:

[0007] (1) Existing equipment has the problem of low cutting accuracy during cutting;

[0008] (2) The existing equipment is inconvenient to clean the waste debris adhering to the inner wall of the corrugated pipe.

[0009] This invention can be achieved through the following technical solution: a rapid cutting and cleaning device for corrugated pipes, including a cutting machine body floatingly connected to a worktable, a main cleaning mechanism for adsorbing dust on the worktable's bottom wall, two top outer clamping plates slidably connected to the worktable on both sides of the cutting machine body to facilitate alignment between the cutting machine body and the corrugated pipe, a shielding plate for blocking excess light source is fixedly installed on the top outer clamping plates, a gap is formed between the two top outer clamping plates, the gap being equal to the thickness of the cutting machine body, and bottom outer clamping plates corresponding one-to-one with the top outer clamping plates are slidably connected to the worktable. The relative movement of the two top outer clamping plates and the bottom outer clamping plates facilitates the fixing of the corrugated pipe to be cut, preventing the corrugated pipe from shifting position during the cutting process, thereby ensuring the overall cutting accuracy of the equipment;

[0010] An auxiliary cleaning mechanism for cleaning dust inside the bellows is installed on the workbench between the top outer clamping plate and the bottom outer clamping plate.

[0011] A further technical improvement of the present invention is that: a driving mechanism is provided on the worktable to allow two top outer clamping plates and two bottom outer clamping plates to slide relative to each other. The driving mechanism includes an annular plate fixed on the worktable. The top and bottom ends of the sidewall of the annular plate are provided with inner grooves. The inner cavities of the two inner grooves are vertically and elastically slidably connected to two L-shaped plates. The two L-shaped plates are fixedly connected to the top outer clamping plate and the bottom outer clamping plate, respectively.

[0012] A further technical improvement of the present invention is that: the side wall of the annular plate is provided with a limiting component to restrict the relative sliding of the two L-shaped plates. The limiting component includes a rotating ring that is rotatably connected to the side wall of the annular plate. Two locking plates that engage with the L-shaped plates are fixedly connected at equal intervals on the inner circumferential wall of the rotating ring. Rotating the rotating ring causes the L-shaped plates to engage with the locking plates.

[0013] A further technical improvement of the present invention is that: the auxiliary cleaning mechanism includes a circular plate fixedly connected to the annular plate, and an inner clamping plate is floatingly connected to the center of the top and bottom walls of the circular plate. An arc-shaped suction head is fixedly installed in the inner cavity of the inner clamping plate. The relative movement of the two inner clamping plates facilitates the fixing of the inner wall of the corrugated pipe with different diameters. After fixing, the arc-shaped suction head is driven to accurately adsorb the waste debris on the inner wall of the corrugated pipe, thereby facilitating the effective cleaning of the waste debris in the corrugated pipe.

[0014] A further technical improvement of the present invention is that: the inner cavity of the circular plate is provided with an adjustment assembly for relative movement of two inner clamping plates. The adjustment assembly includes a rectangular plate fixed to the inner cavity of the circular plate. The inner cavity of the rectangular plate is symmetrically provided with two sliding grooves for sliding of the inner clamping plates. Rollers are rotatably connected to the opposite side of the two inner clamping plates. A rotating rod is rotatably connected through the center of the rectangular plate. Two rotating plates are symmetrically fixedly connected to both ends of the rotating rod and located in the inner cavity of the circular plate. The inner cavity of the rotating plates is provided with a figure-eight shaped through groove for sliding of the rollers.

[0015] A further technical improvement of the present invention is that a rotating disk is fixedly installed at one end of the rotating rod, and the outer peripheral wall of the rotating disk is provided with a plurality of locking holes that are adapted to the L-shaped plate.

[0016] A further technical improvement of the present invention is that: the annular plate is slidably connected to the worktable, and the annular plate and the worktable are fixed by a positioning pin.

[0017] A further technical improvement of the present invention is that: a first telescopic rod is fixedly installed between the L-shaped plate and the top outer clamping plate and the bottom outer clamping plate; a second telescopic rod is fixedly installed between the annular plate and the circular plate; and a third telescopic rod is fixedly installed between the rotating disk and the rotating rod.

[0018] A further technical improvement of the present invention is that the main cleaning mechanism includes a dust storage hopper that is fixedly connected to the bottom wall of the workbench, and a dust collection box is fixedly installed between the two support legs at the bottom of the workbench. The dust collection box and the dust storage hopper are connected by a fan.

[0019] A further technical improvement of the present invention is that the arc-shaped dust suction head is connected to the inner cavity of the dust collection box through a control valve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This invention involves placing a corrugated tube with the marked cutting area onto two inner clamping plates, aligning the marked area with the cutting machine body. The shielding plates on both sides of the cutting machine body effectively block excess light from the outside, preventing workers from looking at the tube at an angle. This ensures the cutting area of ​​the corrugated tube is directly below the cutting machine body. After alignment, one end of the corrugated tube abuts against the annular plate. The relative movement of the two inner clamping plates then clamps the inner wall of the corrugated tube. After clamping the inner wall, the tube is rotated... The circular ring disengages the clamping plate on the inner circumference of the rotating ring from the slot in the L-shaped plate. At this point, the limiting position of the L-shaped plate can be released. The elastic force of the compression spring causes the two L-shaped plates to move relative to each other. This relative movement of the two L-shaped plates facilitates the synchronous movement of the top and bottom outer clamping plates to assist in clamping the outer wall of the corrugated pipe. By clamping the inner and outer walls, the stability of the pipe during cutting is ensured, preventing the cutting position from shifting. This further guarantees the cutting accuracy of the equipment and makes it easier for operators to use.

[0022] 2. This invention uses two inner clamping plates to clamp the corrugated pipe, and a fan to easily adsorb dust and other waste generated during the cutting process. The control valve on the dust suction pipe facilitates the effective cleaning of waste inside the corrugated pipe, thereby ensuring the cleaning effect of the equipment and conveniently meeting the user's needs.

[0042] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0043] Please see Figure 1-3 As shown, a rapid cutting and cleaning device for corrugated pipes includes a workbench 1. Two baffles 2 are symmetrically fixedly installed on the top wall of the workbench 1. The baffles 2 are preferably transparent acrylic plates.

[0046] Please see Figure 2-3 As shown, a clamping mechanism for limiting the corrugated tube is provided on the workbench 1 and directly below the cutting machine body 23. The clamping mechanism includes an annular plate 3 slidably connected to the workbench 1. The top and bottom ends of the side wall of the annular plate 3 are both provided with an inner groove 31. An L-shaped plate 33 is slidably connected to the inner cavity of the inner groove 31. A compression spring 32 is fixedly connected to the inner wall of the inner groove 31 and fixedly connected to the L-shaped plate 33. A first telescopic rod 34 is fixedly installed on the side wall of the L-shaped plate 33. Two shielding plates 37 are symmetrically slidably connected at the top of the side wall of the annular plate 3 and between the two baffles 2. The shielding plates 37 are used to shield excess light sources to prevent workers from looking at them sideways. A top outer clamping plate 35 is fixedly installed at the bottom end of the two shielding plates 37. The first telescopic rod 34 is fixedly connected to the shielding plate 37 on the side near the first telescopic rod 34. The first telescopic rod 34 at the bottom end of the side wall of the annular plate 3 is fixedly connected to a bottom outer clamping plate 36 corresponding to the two top outer clamping plates 35.

[0047] Please see Figure 2-4 As shown, the inner cavity of the workbench 1 is provided with a limiting mechanism to restrict the horizontal sliding of the annular plate 3. The limiting mechanism includes a slider 4 that is slidably connected to the inner cavity of the workbench 1 and corresponds to the annular plate 3. A U-shaped support plate 41 is fixedly installed on the slider 4. The U-shaped support plate 41 is fixedly connected to the annular plate 3. One side of the slider 4 passes through the workbench 1 and extends to the outside of the workbench 1. A moving handle 42 is fixedly connected to the end of the slider 4 that extends to the outside of the workbench 1. The moving handle 42 is fixed to the workbench 1 by a positioning pin 43.

[0048] Please see Figure 1 , 5As shown, the side wall of the annular plate 3 is provided with an auxiliary cleaning mechanism for cleaning the corrugated pipe opening. The auxiliary cleaning mechanism includes at least two second telescopic rods 6 fixedly connected to the side wall of the annular plate 3. A circular plate 5 is fixedly connected to the side of the second telescopic rod 6 away from the annular plate 3. A sliding rod 54 is slidably connected to the center of the top wall and the bottom wall of the circular plate 5. An inner clamping plate 59 is fixedly installed on the side of the sliding rod 54 away from the circular plate 5. An arc-shaped dust suction head 510 is fixedly installed in the inner cavity of the inner clamping plate 59. One end of the arc-shaped dust suction head 510 is fixedly connected to a dust suction pipe 51. The dust collection box 7 and the dust suction pipe 51 are connected through a control valve.

[0049] Please see Figure 6-8 As shown, the inner cavity of the circular plate 5 is provided with a driving assembly for the relative movement of two sliding rods 54. The driving assembly includes a rectangular plate 52 fixed to the inner cavity of the circular plate 5. The inner cavity of the rectangular plate 52 is symmetrically provided with two sliding grooves 53 for the sliding rods 54 to slide. Rollers 55 are rotatably connected to the opposite side of the two sliding rods 54. A rotating rod 56 is rotatably connected through the center of the rectangular plate 52. Two rotating plates 57 are symmetrically fixedly connected to both ends of the rotating rod 56 and located in the inner cavity of the circular plate 5. The inner cavity of the rotating plate 57 is provided with a figure-eight shaped through groove 58 for the rollers 55 to slide.

[0050] Please see Figure 6 As shown, one end of the rotating rod 56 passes through the circular plate 5 and extends to the outside of the circular plate 5. A third telescopic rod 61 is fixedly installed at the end of the rotating rod 56 that extends to the outside of the circular plate 5.

[0051] Please see Figure 1 , 9 As shown, a rotating disk 62 is fixedly installed on the side of the third telescopic rod 61 away from the circular plate 5 and inside the annular plate 3. A handle 63 is fixedly installed on the side of the rotating disk 62 away from the third telescopic rod 61.

[0052] Please see Figure 9-10 As shown, the side wall of the annular plate 3 is provided with a linkage mechanism that restricts the free sliding of the L-shaped plate 33. The linkage mechanism includes a rotating ring 38 rotatably connected to the side wall of the annular plate 3. Two locking plates 39 corresponding to the L-shaped plate 33 are fixedly connected at equal intervals on the inner circumferential wall of the rotating ring 38. The side wall of the L-shaped plate 33 is provided with a locking groove corresponding to the locking plate 39.

[0053] More specifically, the two plates 39 are arranged in a ring array on the inner peripheral wall of the rotating ring 38;

[0054] At least one rotating handle 310 is fixedly installed on the outer peripheral wall of the rotating ring 38.

[0055] The outer peripheral wall of the rotating disk 62 has multiple locking holes that are adapted to the L-shaped plate 33. The multiple locking holes are distributed in a ring array at equal distances on the outer peripheral wall of the rotating disk 62.

[0056] In use, the corrugated tube marked with the cutting point is placed on the two inner clamping plates 59, and the marked point is aligned with the cutting machine body 23. The shielding plates 37 on both sides of the cutting machine body 23 can conveniently block excess light from the outside to prevent the operator from looking at the side, so that the cutting point of the corrugated tube is just below the cutting machine body 23. After alignment, one end of the corrugated tube abuts against the annular plate 3. During operation, the annular plate 3 is slid according to the length of the corrugated tube. When the annular plate 3 is slid, the positioning pin 43 in the moving handle 42 is removed first to release the limitation of the moving handle 42, and then the annular plate 3 is slid to the specified distance and fixed again by the positioning pin 43.

[0057] The bellows is then clamped and fixed. The rotating disk 62 is rotated by the handle 63. The rotation of the rotating disk 62 facilitates the synchronous rotation of the rotating rod 56. The rotation of the rotating rod 56 causes the two rotating plates 57 to rotate synchronously. The rotation of the rotating plates 57 causes the two rollers 55 to slide in the figure-eight through groove 58 in the rotating plate 57. The movement of the two rollers 55 drives the two inner clamping plates 59 to move relative to each other. At this time, the inner wall of the bellows can be clamped by the movement of the two inner clamping plates 59.

[0058] After the inner wall of the corrugated pipe is clamped, the rotating ring 38 is rotated to disengage the clamping plate 39 on the inner circumferential wall of the rotating ring 38 from the groove in the L-shaped plate 33. At this time, the limit of the L-shaped plate 33 can be released. The elastic force of the compression spring 32 causes the two L-shaped plates 33 to move relative to each other. The relative movement of the two L-shaped plates 33 facilitates the auxiliary clamping of the outer wall of the corrugated pipe by the synchronous movement of the top outer clamping plate 35 and the bottom outer clamping plate 36. By clamping the inner and outer walls, the stability of the pipe during cutting is ensured, and the cutting position of the equipment is avoided from shifting.

[0059] The relative movement of the two L-shaped plates 33 facilitates the L-shaped plates 33 entering the corresponding holes in the rotating disk 62, thereby facilitating the limiting of the rotating disk 62 and preventing it from reversing.

[0060] After the corrugated pipe is clamped between its inner and outer walls, the hydraulic telescopic rod 22, the cutting machine body 23, the control valve on the suction pipe 51, and the fan 72 are driven. The hydraulic telescopic rod 22 causes the cutting machine body 23 to move downward, which facilitates the cutting of the corrugated pipe. During the cutting process, the fan 72 helps to absorb dust and other debris generated during the cutting process, and the control valve on the suction pipe 51 helps to clean the debris inside the corrugated pipe, thus ensuring the cleaning effect of the equipment and making it convenient for workers to use.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
