Description

Technical Field

[0001] This utility model belongs to the field of pipe cutting technology, and relates to laser pipe cutting machines, and in particular to a conveying structure for a laser pipe cutting machine. Background Technology

[0002] Laser tube cutting machines are mainly used to cut various hollow round tubes of non-metallic solid materials, such as plastic tubes, PVC tubes, PVB tubes, and other industrial and civil materials. These laser machines use CO2 metal laser tubes and consume approximately 100W-500W of power, making them the preferred processing machinery for small and medium-sized enterprises.

[0003] For example, the laser tube cutting machine disclosed in CN218253465U includes a machine body, a left chuck device, a laser tube cutting machine, and a right chuck device. A lifting assembly is provided above the machine body. The lifting assembly includes a fixed base frame. A double-rotational screw is rotatably installed inside the fixed base frame. Lower moving seats are threaded to both sides of the double-rotational screw. A connecting pad is provided above the fixed base frame. Connecting seats are fixedly installed on both sides of the upper surface of the connecting pad. A double-rotational screw is rotatably installed between the two connecting seats. Upper moving seats are threaded to both sides of the double-rotational screw. A support roller is rotatably installed on the top of the upper moving seat.

[0004] However, in the above-mentioned solution, after the laser tube cutting machine finishes cutting the tube, the tube is automatically transported to the collection box for collection. However, the cut tube is not inspected. Staff need to inspect each tube individually, which is troublesome, consumes a lot of labor, is inconvenient, and affects the efficiency of collection and transportation. Utility Model Content

[0005] This invention provides a conveying structure for a laser pipe cutting machine, which can automatically inspect pipes, thereby saving labor and improving the efficiency of collection and conveying.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a conveying structure for a laser tube cutting machine, comprising a machine body, a laser cutting main body slidably connected to the machine body, and a clamping component fixedly connected to the machine body. The laser cutting main body is located above the clamping component; a slide is fixedly connected to one side of the machine body near the clamping component; an inclined surface is provided on the top surface of the slide; a limiting plate is rotatably connected to the inclined surface; a discharge port is opened below the limiting plate on the inclined surface; and a connection is formed between the limiting plate and the inclined surface that communicates with the discharge port. The feed inlet has a detection plate located below the feed outlet on the inclined surface. Several protrusions are fixedly connected to the detection plate. When the pipe enters the feed outlet, it falls onto the detection plate through the feed inlet, and the protrusions engage with the holes on the pipe. One end of the detection plate is hinged to the inclined surface. An electromagnetic plate is located on the contact surface of the inclined surface at the other end of the detection plate. The detection plate has sensing elements connected to the electromagnetic plate on both sides of the protrusions. When the protrusions engage with the holes on the pipe, the sensing elements control the electromagnetic plate to be energized, the magnetism of the electromagnetic plate disappears, and the detection plate rotates.

[0007] A further preferred embodiment of this invention is that both the detection plate and the limiting plate are arc-shaped plates.

[0008] A further preferred technical solution of this utility model is as follows: the inclined surface is located on the side of the limiting plate away from the feed port and a fixed connection indicator light is provided. The indicator light is connected to the sensing element and has red and green colors. When the protrusion is inserted into the hole on the pipe, the sensing element contacts the pipe and the indicator light turns green. When the pipe is on the protrusion, the sensing element separates from the pipe and the indicator light turns red.

[0009] A further preferred technical solution of this utility model is as follows: a rotating shaft that can abut against the pipe is rotatably connected to both sides of the discharge port. When the pipe falls onto the detection plate, the rotating shaft rotates and drives the pipe to rotate.

[0010] A further preferred embodiment of this utility model is as follows: two motors are fixedly connected to one side wall of the slide, and the output ends of the two motors are respectively connected to two rotating shafts, and the motors drive the rotating shafts to rotate continuously.

[0011] A further preferred embodiment of this invention is that an anti-slip pad is fixedly connected to the surface of the rotating shaft.

[0012] A further preferred embodiment of this utility model is as follows: the width of the feed inlet is equal to the diameter of the pipe; when the pipe passes through the feed inlet, the limiting plate rotates and the width of the feed inlet changes; when the pipe is above the protrusion, the limiting plate rotates.

[0013] A further preferred embodiment of this utility model is that the free end of the limiting plate is provided with an arc-shaped surface.

[0014] A further preferred embodiment of this utility model is as follows: the detection plate is hinged to the slide by a pin, and a torsion spring for driving the detection plate to reset is sleeved on the pin.

[0015] A further preferred embodiment of this invention is that the diameter of the protrusion gradually decreases from bottom to top.

[0016] Compared with the prior art, the present invention has a slide fixedly connected to the body of the machine, and an inclined surface is provided on the top surface of the slide. A limiting plate is rotatably connected to the inclined surface. A feeding port is opened below the limiting plate on the inclined surface. A feeding port communicating with the feeding port is formed between the limiting plate and the inclined surface. A detection plate is provided below the feeding port on the inclined surface. Several protrusions are fixedly connected to the detection plate. One end of the detection plate is hinged to the inclined surface, and an electromagnetic plate is provided on the contact surface of the other end of the inclined surface. Sensors are provided on both sides of the detection plate. Therefore, before conveying the cut pipe, the pipe falls onto the detection plate through the feeding port. When the protrusions can be smoothly inserted into the holes on the pipe, the pipe contacts the sensor. At this time, the pipe is compliant. The sensor controls the electromagnetic plate to be energized. At this time, the magnetism of the electromagnetic plate disappears, and the detection plate rotates under the influence of gravity, thereby screening out the compliant pipe. This design can automatically perform quality inspection after the pipe is cut, thereby reducing labor and improving the efficiency of subsequent conveying and storage by making the inspection process convenient and fast.

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] Figure 1 As shown, a conveying structure for a laser tube cutting machine includes a body 1, a laser cutting main body 2 slidably connected to the body 1, and a clamping component 3 fixedly connected to the body 1. The laser cutting main body 2 is located above the clamping component 3. When laser cutting the tube, the tube is clamped on the clamping component 3, and the tube is fixed. The laser cutting main body 2 then makes holes or grooves and cuts on the surface of the tube, thereby completing the laser cutting of the tube.

[0029] Figures 1-5 As shown, a slide 6 is fixedly connected to one side of the clamping member 3 on the machine body 1. An inclined surface 5 is provided on the top surface of the slide 6. A limiting plate 4 is rotatably connected to the inclined surface 5. A feeding port is opened below the limiting plate 4 on the inclined surface 5. A feeding port 12 communicating with the feeding port is formed between the limiting plate 4 and the inclined surface 5. A detection plate 8 is provided below the feeding port on the inclined surface 5. Several protrusions are fixedly connected to the detection plate 8. When the pipe enters the feeding port, the pipe falls onto the detection plate 8 through the feeding port 12 and the protrusions are inserted into the holes on the pipe. One end of the detection plate 8 is hinged to the inclined surface 5. An electromagnetic plate 16 is provided on the contact surface of the other end of the detection plate on the inclined surface 5. Since the detection plate 8 is made of metal, when the electromagnetic plate 16 is not energized, the electromagnetic plate 16 has magnetism and thus attracts the detection plate 8. Sensing elements 17 connected to the electromagnetic plate 16 are provided on both sides of the protrusions on the detection plate 8.

[0030] Figures 1-5As shown, after the tube is laser-cut, the clamp 3 releases its fixation on the tube. At this time, the tube rolls down the inclined surface 5 on the slide 6 until it passes through the feed port 12 and the discharge port and lands on the detection plate 8. Since the tube is mostly round, the detection plate 8 and the limiting plate 4 are both arc-shaped plates, which can better contact the surface of the tube. The limiting plate 4 plays a role in stopping the tube during this process, preventing the tube from missing the feed port 12, and limiting the rolling range of the tube.

[0031] Figures 1-5 As shown, when the pipe falls onto the detection plate 8, if the protrusion on the detection plate 8 just inserts into the hole on the pipe, then the pipe is a compliant pipe. At this time, the pipe comes into contact with the sensor 17 on the detection plate 8. After sensing, the sensor 17 transmits a command to the electromagnetic plate 16. At this time, the electromagnetic plate 16 is energized and its magnetism disappears. The detection plate 8 rotates due to the weight of the pipe and gravity, thereby opening the discharge port. At this time, the compliant pipe falls into the slide 6 for collection.

[0032] Figures 1-5 As shown, the detection plate 8 is hinged to the slide 6 via a pin 9. A torsion spring 18 is sleeved on the pin 9 to drive the detection plate 8 to reset. Therefore, when the magnetism of the electromagnetic plate 16 disappears, the detection plate 8 rotates around the pin 9 due to gravity and the weight of the pipe. At this time, the torsion spring 18 deforms due to the force. When the pipe falls into the slide 6, the weight on the detection plate 8 is reduced, and the deformed torsion spring 18 drives the detection plate 8 to rotate in the opposite direction, thereby resetting and closing the outlet 14. At this time, the sensing element 17 does not sense the pipe, thus sending a command to the electromagnetic plate 16. The electromagnetic plate 16 is de-energized and the magnetism is restored, thereby attracting the detection plate 8, making it easier to catch the pipe next time.

[0033] Figures 1-5 As shown, the top surface of the sensing element 17 and the inner bottom surface of the detection plate 8 are at the same level, which can prevent the sensing element 17 from affecting the insertion of the protrusion 10 into the hole of the pipe.

[0034] Figures 1-5 As shown, the diameter of the protrusion gradually decreases from bottom to top. Therefore, when the pipe falls into the discharge port 14, it is easy for the protrusion 10 to be inserted into the hole of the pipe for quality inspection, which further improves the convenience of quality inspection.

[0035] Figures 1-5As shown, the width of the inlet 12 is equal to the diameter of the pipe, which facilitates the pipe to enter the outlet 14 through the inlet 12. When the pipe passes through the inlet 12, the limiting plate 4 rotates due to the pushing of the pipe, thereby increasing the width of the inlet 12. When the pipe is non-compliant and located above the protrusion, the limiting plate 4 also rotates due to the pushing of the pipe. At this time, the operator can open the outlet 14 by continuing to rotate the limiting plate 4 to remove the non-compliant pipe. Afterwards, the limiting plate 4 can be manually reset.

[0036] Figures 1-5 As shown, the free end of the limiting plate 4 is provided with an arc-shaped surface 15, which can further facilitate the pipe to enter the feed port 12 and prevent the pipe from getting stuck outside the feed port 12.

[0037] Figures 1-5 As shown, the inclined surface 5 is located on the side of the limiting plate 4 away from the discharge port, and the fixed connection port indicator light 11 is connected to the sensing element 17. The indicator light 11 has red and green lights. When the protrusion is inserted into the hole on the pipe, the sensing element 17 contacts the pipe and the indicator light 11 lights up green. When the pipe is on the protrusion, the sensing element 17 separates from the pipe and the indicator light 11 lights up red.

[0038] Figures 1-5 As shown, when a non-compliant pipe falls onto the detection plate 8, the protrusion cannot be fully inserted into the hole of the pipe, so the sensor does not detect the pipe. At this time, the indicator light 11 turns red to warn the staff. When the red light continues to illuminate, the staff can open the discharge port 14 by rotating the limit plate 4 to remove the abnormal pipe for separate inspection. This design serves to warn of abnormal pipes and reduces the number of pipes that staff need to inspect, thereby reducing labor and improving the convenience of quality inspection.

[0039] Figures 1-7 As shown, rotating shafts 13 are rotatably connected to both sides of the discharge port, which can abut against the pipe. When the pipe falls on the detection plate 8, the rotating shafts 13 rotate and drive the pipe to rotate. Two motors 7 are fixedly connected to one side wall of the slide 6. The output ends of the two motors 7 are respectively connected to the two rotating shafts 13. The motors 7 drive the rotating shafts 13 to rotate continuously. Anti-slip pads are fixedly connected to the surface of the rotating shafts 13.

[0040] Figures 1-7 As shown, the motor 7 drives the rotating shaft 13 to rotate continuously. When the pipe enters the discharge port 14, the rotating shaft 13 drives the pipe to rotate, thereby preventing the holes on the pipe from misaligning with the protrusions 10. The anti-slip pad can increase the friction between the pipe and the rotating shaft 13, so that the rotating shaft 13 can drive the pipe to rotate better, making it easier for the protrusions 10 to be inserted into the holes of the pipe, further improving the convenience of quality inspection.
