Description
Technical Field
[0001] This utility model relates to the field of plastic pipe processing technology, specifically a punching device for processing plastic pipes. Background Technology
[0002] In the production and processing of plastic pipes, when plastic pipes are used as irrigation pipes, it is necessary to punch holes in the irrigation pipes to form water spray holes and achieve uniform water spraying. Therefore, a punching device is required.
[0003] A Chinese patent with authorization announcement number CN220373423U discloses a punching device for processing plastic pipes, including a gantry frame with a sliding groove on the top. A cylinder is slidably mounted on the gantry frame, with the cylinder's drive end sliding within the sliding groove. The cylinder's drive end is fixedly connected to a connecting seat, which houses a small motor. Two clamping blocks are slidably mounted in rectangular slots. A drive assembly is provided on the gantry frame, and a transmission assembly is located on one side of the base. By bringing the two clamping blocks close together, plastic pipes of different diameters can be clamped and fixed, preventing the plastic pipes from shaking during punching and affecting the punching effect. By controlling the drive motor, the spacing of the holes can be controlled to meet different usage conditions. The device is simple to operate and improves work efficiency.
[0004] However, the aforementioned punching device still has some problems. In practical applications, the punched discs will fall directly into the plastic tube. Some plastic tubes are quite long, making it difficult to remove the discs, which can cause blockages when the tube is used later. Therefore, a punching device for processing plastic tubes is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a punching device for processing plastic pipes.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A punching device for processing plastic pipes, comprising a workbench, a fixing frame installed at the top edge of the workbench, a groove inside the bottom end of the fixing frame, a telescopic rod installed on the inner wall of the top side of the groove, an mounting plate installed at the working end of the telescopic rod, a collection box installed on one side of the mounting plate, a negative pressure motor installed on one side of the collection box, a rotating shaft installed at the output end of the negative pressure motor, three fan blades equidistantly installed at one end of the rotating shaft, a filter screen installed on the inner wall of the collection box, an exhaust pipe connected to one top end of the collection box, and the other end of the rotating shaft extending movably through the filter screen. Two thin rods are symmetrically installed on the outside of the collection box. A rotating cylinder is mounted on the outside of the thin rods. One end of the rotating cylinder is rotatably mounted on one side of the collection box. Several dust suction holes are equidistantly opened on the outside of the rotating cylinder. A spiral auger is assembled on the outside of the rotating cylinder. During the rotation of the spiral auger, it can form a continuous conveying force. When the perforated disc produced by punching enters the inside of the rotating cylinder, the spiral auger will quickly convey the perforated disc along the axial direction of the rotating cylinder, avoiding the accumulation of the perforated disc in the plastic tube. At the same time, the dust suction holes can form a strong suction force under the action of the negative pressure motor. The fine dust generated during the punching process will be quickly sucked into the collection box through these dust suction holes, reducing the pollution to the working environment.
[0007] Preferably, a servo motor is installed on one side of the worktable, and a bidirectional lead screw is installed at the output end of the servo motor. Two sliding grooves are symmetrically opened at the middle of the worktable, and sliding blocks are slidably installed inside the sliding grooves. Screw holes are opened inside the sliding blocks, and one end of the bidirectional lead screw passes through the screw holes and is rotatably installed inside one side of the sliding groove. Fixed clamping plates are installed on the top side of each sliding block. By controlling the rotation direction and number of revolutions of the servo motor, the distance between the two fixed clamping plates can be flexibly adjusted, thereby achieving the fixation of plastic tubes of different sizes. This effectively prevents the plastic tubes from shifting or rotating, ensuring the accuracy of the punching position.
[0008] Preferably, a reciprocating motor is installed on one side of the top of the fixing frame, and a threaded rod is installed on the output end of the reciprocating motor. A slide rail is provided inside the top side of the fixing frame, and a slider is slidably installed inside the slide rail. A threaded hole is provided inside the slider. One end of the threaded rod passes through the threaded hole and is rotatably installed inside one side of the fixing frame. By controlling the rotation of the reciprocating motor, the position of the slider in the lateral direction can be precisely adjusted, thereby driving the punching assembly installed at the bottom of the slider to move in the lateral direction, enabling the punching assembly to perform punching operations at different positions on the plastic tube.
[0009] Preferably, a cylinder is mounted on the bottom side of the slider, a mounting frame is mounted on the working end of the cylinder, a drive motor is mounted on one side of the mounting frame, a rotating shaft is mounted on the output end of the drive motor, four mounting blocks are equidistantly mounted on the outer side of the rotating shaft, mounting rings are movably fitted on the outer side of each mounting block, and punching heads are mounted on the bottom side of each mounting ring. The punching heads are all of different sizes, and fastening bolts are rotatably fitted through each mounting block. By controlling the rotation of the rotating shaft through the drive motor, punching heads of different sizes can be easily rotated to meet the punching requirements of different hole diameters in plastic tubes. When it is necessary to replace the punching head, simply loosen the fastening bolts to remove the mounting ring from the mounting block, then replace it with a new punching head and retighten the fastening bolts.
[0010] Preferably, a collection trough is provided inside the other end of the workbench. The collection trough is located on the bottom side of one end of the auger. A movable door is installed on one side of the collection box through a hinge. After the auger delivers the perforated plate, the perforated plate will fall directly into the collection trough. When a certain amount of dust is collected in the collection box, the operator can open the movable door to clean the filter screen in the collection box to ensure the filtration effect of the filter screen.
[0011] Preferably, a control panel is installed on one side of the mounting bracket, and the control panel is electrically connected to the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device.
[0012] The advantages of this utility model are:
[0013] 1. The telescopic rod of this utility model extends to push the mounting plate, so that the spiral auger fits against the inner wall of the bottom side of the pipe. The negative pressure motor starts, and the rotating shaft drives the fan blade to rotate, creating a negative pressure in the collection box. The fine dust generated by punching is sucked in through the dust suction hole on the rotating cylinder. After being filtered by the filter screen, the air is discharged from the exhaust pipe. At the same time, the rotating shaft drives the thin rod to rotate the rotating cylinder, and the spiral auger rotates synchronously, pushing the perforated plate axially into the collection groove, effectively preventing the perforated plate from accumulating in the pipe.
[0014] 2. This utility model controls the rotation of the shaft by a drive motor. The shaft drives the mounting block to rotate, and the punching heads of different sizes mounted on it rotate accordingly. When the required punching head rotates to the working position, the drive motor stops to adapt to different punching requirements. Subsequently, the cylinder extends, pushing the mounting frame and punching head downward to punch the pipe. After completing one punching, the cylinder retracts. If a new punching head needs to be replaced, the fastening bolts can be loosened, the mounting ring can be removed to replace the new punching head, and then the bolts can be tightened to fix it.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figure 1-4As shown, a punching device for processing plastic pipes includes a workbench 1. A fixing frame 2 is installed on the top edge of the workbench 1. A groove is formed inside the bottom end of the fixing frame 2. A telescopic rod 3 is installed on the top inner wall of the groove. An installation plate 4 is installed on the working end of the telescopic rod 3. A collection box 5 is installed on one side of the installation plate 4. A negative pressure motor 6 is installed on one side of the collection box 5. A rotating shaft 7 is installed at the output end of the negative pressure motor 6. Three fan blades 8 are installed at equal intervals on one end of the rotating shaft 7. A filter screen 9 is installed on the inner wall of the collection box 5. An exhaust pipe 10 is connected to one end of the top side of the collection box 5. The other end of the rotating shaft 7 extends movably through the filter screen 9 to the outside of the collection box 5 and has two thin rods 11 symmetrically installed. A rotating cylinder 12 is installed on the outside of the thin rods 11. One end of the rotating cylinder 12 is rotatably installed on one side of the collection box 5. A plurality of dust suction holes 13 are formed at equal intervals on the outside of the rotating cylinder 12. A spiral auger 14 is assembled on the outside of the rotating cylinder 12.
[0024] The other end of the workbench 1 is provided with a collection trough 15, which is located on the bottom side of one end of the spiral auger 14. The collection box 5 is provided with a movable door 33 on one side by means of a hinge.
[0025] A control panel 34 is installed on one side of the fixing frame 2. The control panel 34 is electrically connected to the electrical components inside the device. During operation, in practical applications, the punching discs produced during punching will fall directly into the plastic tube. Some plastic tubes are quite long, making it difficult to remove the punching discs, which can cause blockages in subsequent use. During the punching process, the telescopic rod 3 extends, pushing the mounting plate 4 and the connected collection box 5, rotating cylinder 12, and auger 14 downwards until the auger 14 contacts the inner wall of the bottom side of the tube, preparing for chip removal. The negative pressure motor 6 starts, carrying... The rotating shaft 7 and fan blades 8 rotate, and the rotation of fan blades 8 creates negative pressure in the collection box 5. Fine dust is sucked into the collection box 5 through the dust suction hole 13 on the outside of the rotating cylinder 12. After being filtered by the filter screen 9, the air is discharged from the exhaust pipe 10. At the same time, the rotation of the rotating shaft 7 causes the thin rod 11 to drive the rotating cylinder 12 to rotate. The spiral auger 14 rotates synchronously with the rotating cylinder 12, conveying the perforated discs produced by punching along the axial direction. Finally, the perforated discs fall into the collection groove 15 in the workbench 1, which avoids the perforated discs from accumulating in the plastic tube. When dust accumulates in the collection box 5 and affects the filtration effect, the movable door 33 can be opened to clean the filter screen 9.
[0026] Please see Figure 1 , 2As shown in Figures 3 and 5, a servo motor 16 is installed on one side of the workbench 1, and a bidirectional lead screw 17 is installed at the output end of the servo motor 16. Two slide grooves 18 are symmetrically opened at the middle position of the workbench 1. A sliding block 19 is slidably installed inside the slide groove 18. A screw hole is opened inside the sliding block 19. One end of the bidirectional lead screw 17 passes through the screw hole and is rotatably installed inside one side of the slide groove 18. A fixing clamp 20 is installed on the top side of each sliding block 19.
[0027] A reciprocating motor 21 is installed on one side of the top of the fixed frame 2. A threaded rod 22 is installed at the output end of the reciprocating motor 21. A slide rail 23 is provided inside the top side of the fixed frame 2. A slider 24 is slidably installed inside the slide rail 23. A threaded hole is provided inside the slider 24. One end of the threaded rod 22 passes through the threaded hole and is rotatably installed inside one side of the fixed frame 2.
[0028] A cylinder 25 is mounted on the bottom side of the slider 24. A mounting frame 26 is mounted on the working end of the cylinder 25. A drive motor 27 is mounted on one side of the mounting frame 26. A rotating shaft 28 is mounted on the output end of the drive motor 27. Four mounting blocks 29 are equidistantly mounted on the outer side of the rotating shaft 28. A mounting ring 30 is movably mounted on the outer side of the mounting block 29. A punch head 31 is mounted on the bottom side of each mounting ring 30. The punch heads 31 are all of different sizes. The mounting ring 30 is rotatably mounted with fastening bolts 32 through the mounting block 29. During operation, in the plastic pipe production process, when the plastic pipe is used as an irrigation pipe, it is necessary to punch holes in the irrigation pipe to form water spray holes to achieve uniform water spraying. Therefore, a punching device is required. First, the pipe is sleeved on the outside of the spiral auger 14. The bidirectional screw 17 is driven to rotate by the servo motor 16. The rotation of the bidirectional screw 17 will cause the two fixed clamping plates 20 to move in opposite directions along the slide groove 18, thereby clamping pipes of different diameters.
[0029] Next, when it is necessary to adjust the lateral position of the punch, the reciprocating motor 21 is started through the control panel 34. The reciprocating motor 21 drives the threaded rod 22 to rotate. The slider 24 will slide laterally in the slide rail 23 because the internal threaded hole cooperates with the threaded rod 22, thereby driving the bottom cylinder 25, the mounting frame 26 and the punching assembly to move, so as to achieve precise positioning of the punching position.
[0030] According to the required hole diameter of the pipe, the drive motor 27 controls the rotating shaft 28 to rotate. The rotating shaft 28 drives the mounting block 29 to rotate, and the punch heads 31 of different sizes mounted on it rotate accordingly. When the required punch head 31 rotates to the working position, the drive motor 27 stops to adapt to different punching requirements. Then, the cylinder 25 extends, pushing the mounting frame 26 and the punch head 31 to move downward to punch the pipe. After completing one punching, the cylinder 25 retracts. If a new punch head 31 needs to be replaced, the fastening bolt 32 can be loosened, the mounting ring 30 can be removed to replace the new punch head 31, and then the bolt can be tightened to fix it.
[0031] Working principle: First, the pipe is sleeved on the outside of the spiral auger 14. The servo motor 16 drives the bidirectional screw 17 to rotate. The rotation of the bidirectional screw 17 will cause the two fixed clamping plates 20 to move in opposite directions along the slide groove 18, thereby clamping pipes of different diameters.
[0032] Next, when it is necessary to adjust the lateral position of the punch, the reciprocating motor 21 is started through the control panel 34. The reciprocating motor 21 drives the threaded rod 22 to rotate. The slider 24 will slide laterally in the slide rail 23 because the internal threaded hole cooperates with the threaded rod 22, thereby driving the bottom cylinder 25, the mounting frame 26 and the punching assembly to move, so as to achieve precise positioning of the punching position.
[0033] According to the required hole diameter of the pipe, the drive motor 27 controls the rotating shaft 28 to rotate. The rotating shaft 28 drives the mounting block 29 to rotate, and the punch heads 31 of different sizes mounted on it rotate accordingly. When the required punch head 31 rotates to the working position, the drive motor 27 stops to adapt to different punching requirements. Then, the cylinder 25 extends, pushing the mounting frame 26 and the punch head 31 to move downward to punch the pipe. After completing one punching, the cylinder 25 retracts. If a new punch head 31 needs to be replaced, the fastening bolt 32 can be loosened, the mounting ring 30 can be removed to replace the new punch head 31, and then the bolt can be tightened to fix it.
[0034] During the punching process, the telescopic rod 3 extends, pushing the mounting plate 4 and the connected collection box 5, rotating cylinder 12 and spiral auger 14 downwards until the spiral auger 14 contacts the inner wall of the bottom side of the pipe, preparing for chip removal. The negative pressure motor 6 starts, driving the rotating shaft 7 and fan blade 8 to rotate. The rotation of the fan blade 8 creates negative pressure in the collection box 5, and fine dust is sucked into the collection box 5 through the dust suction hole 13 on the outside of the rotating cylinder 12. After being filtered by the filter screen 9, the air is discharged from the exhaust pipe 10. At the same time, the rotation of the rotating shaft 7 causes the thin rod 11 to drive the rotating cylinder 12 to rotate. The spiral auger 14 rotates synchronously with the rotating cylinder 12, conveying the punched discs axially. Finally, the discs fall into the collection trough 15 in the workbench 1, preventing the discs from accumulating in the plastic pipe. When dust accumulates in the collection box 5 and affects the filtration effect, the movable door 33 can be opened to clean the filter screen 9.
