Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a three-dimensional laser cutting machine for plastic pipes. Background Technology

[0002] Plastic pipes are a high-tech composite chemical building material, belonging to the fourth major category of new building materials after steel, wood, and cement. They possess advantages such as energy saving, material saving, environmental friendliness, lightweight and high strength, corrosion resistance, smooth inner walls that do not scale, easy construction and maintenance, and long service life. They are widely used in building water supply and drainage, urban water supply and drainage, and gas pipelines. However, the length of plastic pipes often exceeds the actual required dimensions. To meet specific application needs, they must be cut to the appropriate length, thus requiring the use of a 3D laser cutting machine. 3D laser cutting machines use a non-contact cutting method when cutting plastic pipes, meaning the laser beam acts directly on the material surface without physical contact with the workpiece. This reduces potential mechanical stress and deformation during the cutting process. Furthermore, laser cutting machines provide high-precision cutting quality with smooth edges, eliminating the need for subsequent finishing processes. This is particularly important for processing plastic pipes that require high precision and a high-quality appearance.

[0003] An existing patent (application number 202120080859.3) discloses a dust removal laser cutting machine, including a worktable, a mounting plate slidably connected to the worktable, and a laser cutting head slidably connected to the mounting plate. The mounting plate is provided with a dust removal device, which includes a dust removal fan connected to the end of the mounting plate, a dust suction pipe connected to the dust removal fan, and a dust collection part connected to the dust suction pipe. The end of the dust suction pipe facing away from the dust removal fan is close to the laser cutting head, and the dust collection part is connected to the side wall of the mounting plate.

[0004] Therefore, existing 3D laser cutting machines do not have a good dust collection structure when performing laser cutting, especially when cutting plastic pipes, which makes it easier to generate dust. If this dust is not treated, it will accumulate on the cutting table, which will not only affect the cutting of the device, but also affect the working environment due to the dust spreading. Utility Model Content

[0005] Therefore, it is necessary to address the technical problem that 3D laser cutting machines lack a good dust collection structure during laser cutting, especially when cutting plastic pipes, where dust is more easily generated. If this dust is not handled properly, it will accumulate on the cutting table, affecting not only the cutting process but also the working environment. Therefore, a 3D laser cutting machine for plastic pipes should be provided.

[0006] A three-dimensional laser cutting machine for plastic pipes includes a cutting worktable. Four support columns are fixedly installed at the lower front and lower rear of the cutting worktable. Anti-slip pads are fixedly installed at the lower ends of all eight support columns. A sliding groove is formed at the front of the cutting worktable, within which a support seat is slidably installed. A dust collection device is fixedly installed on the upper end of the support seat. An adjustment device is fixedly installed at the right end of the sliding groove. Clamping devices are fixedly installed at the upper front and upper rear of the cutting worktable. The laser cutting machine body is installed in the middle of the upper part of the cutting worktable. A controller is fixedly installed at the right rear of the cutting worktable. The dust collection device includes a fan and an exhaust pipe. The machine has an air outlet at the front end and an air inlet at the rear end. A filter screen is fixedly installed at the front end of the exhaust pipe, and a mounting box is fixedly installed at the lower end of the exhaust pipe. A receiving box is installed at the right end of the mounting box. The adjustment device includes a servo motor, and a threaded rod is fixedly installed at the output end of the servo motor. A slider is fixedly installed at the rear end of the support base, and a threaded groove is opened through the right end of the slider. The clamping device includes a first fixed base and a second fixed base. An electric telescopic rod is fixedly installed at one end of each of the first and second fixed bases. A clamping seat is fixedly installed at the output end of each of the two electric telescopic rods, and a clamping groove is opened at one end of each of the two clamping seats.

[0007] In one embodiment, the exhaust pipe is inserted and fixedly installed on the air inlet, and the fan is fixedly installed on the upper end of the support base.

[0008] Before use, connect the controller to an external power source. When the laser cutting machine is cutting plastic pipes and generating dust, start the fan on the dust collection device. The suction pipe installed on the fan inlet will generate suction, which will suck in the debris and dust generated by the plastic pipes, thus preventing a large amount of dust from accumulating on the cutting table. The sucked debris and dust will be filtered by the filter screen and fall into the receiving box on the mounting box, preventing these debris and dust from entering the fan.

[0009] In one embodiment, the slider is threaded onto a threaded rod via a threaded groove, and the slider is located within the groove. The threaded rod is rotatably mounted within the groove, and the servo motor is inserted and fixedly mounted at the right end of the groove.

[0010] When the fan is running, the servo motor on the adjustment device is activated, which in turn drives the threaded rod to rotate in the slide groove. At this time, the slider on the outer surface of the threaded rod slides and adjusts in the slide groove, thereby adjusting the support base and the fan on it. This allows the exhaust pipe to adjust its dust suction position as needed, further improving the dust removal effect of the device.

[0011] In one embodiment, the first fixing seat is fixedly installed on the upper left side of the cutting worktable, and the second fixing seat is fixedly installed on the upper right side of the cutting worktable.

[0012] Place the plastic pipe between the two clamping seats. Then, activate the two electric telescopic rods. The two electric telescopic rods can push the clamping seats, which can then fix the plastic pipe in place. Moreover, the arc-shaped clamping grooves on the clamping seats can not only fit the round plastic pipe better, but the two clamping seats can also be adjusted to clamp round plastic pipes of different sizes.

[0013] In one embodiment, a slot is provided in the middle of the upper part of the cutting workbench, and a receiving box is engaged in the slot.

[0014] Material receiving boxes are also installed on the cutting worktable. These boxes can initially collect the dust generated during cutting, and then extract it through the exhaust pipe.

[0015] In one embodiment, the exhaust duct is T-shaped.

[0016] In one embodiment, both the first fixing seat and the second fixing seat are L-shaped and symmetrically distributed from left to right.

[0017] In one embodiment, the clamping groove is an arc-shaped groove.

[0018] In one embodiment, the anti-slip pad is made of rubber.

[0019] In one embodiment, the controller is electrically connected to the laser cutting machine body, the fan, the servo motor, and the electric telescopic rod.

[0020] 1. The aforementioned three-dimensional laser cutting machine for plastic pipes, when cutting plastic pipes, first places the plastic pipe between two clamping seats on the clamping device. Then, by activating two electric telescopic rods, the clamping seats are pushed, thus fixing the plastic pipe in place. The arc-shaped clamping grooves on the clamping seats not only better fit the round plastic pipe, but the two clamping seats are also adjustable to hold round plastic pipes of different sizes. After the plastic pipe is clamped, the laser cutting machine body cuts the pipe. When the cutting process generates dust, activating the fan on the dust collection device generates suction through the exhaust pipe installed at the fan inlet. It can suck up debris and dust generated by plastic pipes, preventing a large amount of dust from accumulating on the cutting table. The sucked debris and dust are filtered by a filter screen and fall into the receiving box on the mounting box, preventing them from entering the fan. When the fan is running, the servo motor on the adjustment device is activated, which in turn drives the threaded rod to rotate in the slide groove. At this time, the slider on the outer surface of the threaded rod slides and adjusts in the slide groove, thereby adjusting the support base and the fan on it. This allows the exhaust pipe to be adjusted to the dust suction position as needed, further improving the dust removal effect of the device. In addition, receiving boxes are also installed on the cutting table. The receiving boxes can initially collect the dust generated during cutting, and then extract it through the exhaust pipe.

[0031] Please refer to the following: Figures 1 to 5 This utility model provides a three-dimensional laser cutting machine for plastic pipes, including a cutting worktable 1. Four support columns 8 are fixedly installed at the front and rear of the lower end of the cutting worktable 1. Anti-slip pads 9 are fixedly installed at the lower ends of all eight support columns 8. A sliding groove 10 is opened at the front end of the cutting worktable 1, and a support seat 5 is slidably installed within the groove 10. A dust collection device 2 is fixedly installed on the upper end of the support seat 5. An adjustment device 3 is fixedly installed at the right end of the sliding groove 10. Clamping devices 4 are fixedly installed at the front and rear of the upper end of the cutting worktable 1. A laser cutting machine body 6 is installed in the middle of the upper end of the cutting worktable 1. A controller 7 is fixedly installed at the rear right end of the cutting worktable 1. The dust collection device 2 includes a fan 20 and an exhaust pipe 21. An air outlet 25 is installed at the front end of the fan 20, and an air inlet 25 is installed at the rear end of the fan 20. The exhaust pipe 21... A filter screen 24 is fixedly installed at one end of the exhaust pipe 21, and a mounting box 22 is fixedly installed at the lower end of the exhaust pipe 21. A receiving box 23 is installed at the right end of the mounting box 22. The adjustment device 3 includes a servo motor 30, and a threaded rod 31 is fixedly installed at the output end of the servo motor 30. A slider 32 is fixedly installed at the rear end of the support base 5, and a threaded groove 33 is opened through the right end of the slider 32. The clamping device 4 includes a first fixed base 40 and a second fixed base 41. An electric telescopic rod 42 is fixedly installed at one end of each of the first fixed base 40 and the second fixed base 41. A clamping seat 43 is fixedly installed at the output end of each of the two electric telescopic rods 42, and a clamping groove 44 is opened at one end of each of the two clamping seats 43. The controller 7 is electrically connected to the laser cutting machine body 6, the fan 20, the servo motor 30, and the electric telescopic rod 42. The anti-slip pad 9 is made of rubber.

[0032] The exhaust pipe 21 is inserted and fixedly installed on the air inlet, and the fan 20 is fixedly installed on the upper end of the support base 5; the exhaust pipe 21 is T-shaped.

[0033] Before use, connect the controller 7 to an external power source. When the laser cutting machine body 6 cuts the plastic pipe and generates dust, the fan 20 on the dust collection device 2 is started. The exhaust pipe 21 installed on the air inlet of the fan 20 generates suction, which can suck in the debris and dust generated by the plastic pipe, thus preventing a large amount of dust from accumulating on the cutting worktable 1. The sucked debris and dust are filtered by the filter screen 24 and fall into the receiving box 23 on the mounting box 22, preventing these debris and dust from entering the fan 20.

[0034] The slider 32 is threaded onto the threaded rod 31 through the threaded groove 33, and the slider 32 is located in the slide groove 10. The threaded rod 31 is rotatably mounted in the slide groove 10, and the servo motor 30 is inserted and fixedly mounted on the right end of the slide groove 10.

[0035] When the fan 20 is running, the servo motor 30 on the adjustment device 3 is started, and the servo motor 30 drives the threaded rod 31 to rotate in the slide groove 10. At this time, the slider 32 on the outer surface of the threaded rod 31 slides and adjusts in the slide groove 10, so that the support base 5 and the fan 20 on it slide and adjust accordingly, so that the exhaust pipe 21 can adjust its dust suction position as needed, further improving the dust removal effect of the device.

[0036] The first fixing seat 40 is fixedly installed on the upper left side of the cutting worktable 1, and the second fixing seat 41 is fixedly installed on the upper right side of the cutting worktable 1; the clamping groove 44 is an arc-shaped groove; the first fixing seat 40 and the second fixing seat 41 are both L-shaped and symmetrically distributed on the left and right.

[0037] The plastic pipe is placed between two clamping seats 43. At this time, by activating two electric telescopic rods 42, the two electric telescopic rods 42 can push the clamping seats 43 on them, and the clamping seats 43 can fix the plastic pipe. Moreover, the design of the arc-shaped clamping groove 44 on the clamping seat 43 can not only fit the round plastic pipe better, but also the two clamping seats 43 can be adjusted to clamp round plastic pipes of different sizes.

[0038] The upper middle part of the cutting workbench 1 has a slot 50, and a receiving box 51 is attached to the slot 50.

[0039] A receiving box 51 is also installed on the cutting workbench 1. The receiving box 51 can initially collect the dust generated during cutting, and then extract it through the exhaust pipe 21.

[0040] This invention provides a three-dimensional laser cutting machine for plastic pipes. When cutting plastic pipes, the plastic pipe is first placed between two clamping seats 43 on the clamping device 4. Then, by activating two electric telescopic rods 42, the clamping seats 43 are pushed, thus securing the plastic pipe. The arc-shaped clamping grooves 44 on the clamping seats 43 not only better fit the round plastic pipe, but the two clamping seats 43 are also adjustable to hold round plastic pipes of different sizes. After the plastic pipe is clamped, it is cut by the laser cutting machine body 6. When the cutting process generates dust, the fan 20 on the dust collection device 2 is activated. The suction pipe 21 installed on the air inlet of the fan 20 generates suction, which removes dust from the plastic pipe. The dust and debris generated by the material are sucked in, preventing a large amount of dust from accumulating on the cutting workbench 1. The sucked-in dust and debris are filtered by the filter screen 24 and fall into the receiving box 23 on the mounting box 22, preventing these dust and debris from entering the fan 20. In addition, when the fan 20 is running, the servo motor 30 on the adjustment device 3 is activated, which in turn drives the threaded rod 31 to rotate in the slide groove 10. At this time, the slider 32 on the outer surface of the threaded rod 31 slides and adjusts in the slide groove 10, thereby allowing the support base 5 and the fan 20 on it to slide and adjust accordingly. This allows the exhaust pipe 21 to adjust its dust suction position as needed, further improving the dust removal effect of the device. In addition, a receiving box 51 is also installed on the cutting workbench 1. The receiving box 51 can initially collect the dust generated during cutting, and then extract it through the exhaust pipe 21.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
