[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0030] Please refer to Figure 1 and Figure 2 As shown, a laser tube cutting machine comprises a feeding mechanism 1, a propulsion mechanism 2 and a laser cutting device 3; the feeding mechanism 1 comprises a first conveyor belt 11 and a transfer robot 12, the first conveyor belt 11 is used to transport the tube to be processed, and the transfer robot 12 is used to transfer the tube to be processed on the first conveyor belt 11 to the propulsion mechanism 2;

[0031] The propulsion mechanism 2 includes a workbench 21, a movable clamping claw 22 and a static clamping claw 23; the workbench 21 is provided with a track 211 along the length direction, and the workbench 21 is provided with a liftable support wheel 212 along the length direction, and the wheel surface of the support wheel 212 is provided with a groove 2121 along the circumferential direction, and the groove 2121 is used to sink the pipe to be processed;

[0032] The movable claw 22 is slidably disposed on the track 211, and the static claw 23 is disposed on the workbench 21, and the static claw 23 is located at one end of the track 211;

[0033] The feeding end of the laser cutting device 3 is located at an end of the static clamping jaw 23 away from the movable clamping jaw 22 .

[0034] From the above description, it can be seen that the beneficial effect of the present invention is that the pipe to be processed can be transported by the first conveyor belt 11, and then the transfer robot 12 clamps the pipe to be processed and transfers it to the support wheel 212 on the workbench 21, and then the groove 2121 of the support wheel 212 prevents the pipe to be processed from falling from the support wheel 212, and then the transfer robot 12 is reset, and then the movable claw 22 approaches one end of the pipe to be processed along the track 211 and clamps it, and then the movable claw 22 continues to move along the track 211 toward the static claw 23 until the other end of the pipe to be processed is stuck in the static claw 23, and then the support wheel 212 descends to avoid the movable claw 22, and finally the movable claw 22 can continuously push the pipe to be processed so that the pipe to be processed enters the laser cutting equipment 3 for laser cutting.

[0035] Please refer to Figure 3 As shown, further, a lifting mechanism 4 is arranged below the support wheel 212, and the lifting mechanism 4 includes a support frame 41, a movable frame 42 and a first cylinder 43; the support frame 41 is arranged in the workbench 21, the movable frame 42 is connected to the support wheel 212, and the movable frame 42 is vertically slidably arranged on the support frame 41 and is connected to the movable end of the first cylinder 43.

[0036] It can be known from the above description that the first cylinder 43 drives the movable end to move, which can drive the movable bracket 42 to move in the vertical direction of the support frame 41, thereby controlling the lifting and lowering of the support wheel 212.

[0037] Please refer to Figure 3 As shown, further, the groove 2121 includes a first notch 2121-1, a second notch 2121-2 and a third notch 2121-3 that are interconnected, and the width and depth of the first notch 2121-1 to the second notch 2121-2 gradually increase, and the width and depth of the second notch 2121-2 to the third notch 2121-3 gradually decrease.

[0038] From the above description, it can be seen that since the groove 2121 has the first slot 2121-1, the second slot 2121-2 and the third slot 2121-3 which are interconnected, and the width and depth from the first slot 2121-1 to the second slot 2121-2 gradually increase, and the width and depth from the second slot 2121-2 to the third slot 2121-3 gradually decrease, before the loading process, the support wheel 212 can be rotated according to the size of the pipe to be processed, so that the width and depth of the groove 2121 for placing the pipe to be processed can be better adapted.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4As shown, further, the transfer robot 12 includes a second conveyor belt 121, a first motor group 122, a first moving seat 123 and a pneumatic claw 124; the first motor group 122 is connected to the driving wheel of the second conveyor belt 121, the first moving seat 123 is connected to the belt of the second conveyor belt 121, and the pneumatic claw 124 is arranged on the first moving seat 123.

[0040] From the above description, it can be seen that when transferring the pipe to be processed, the pneumatic claw 124 clamps the pipe to be processed, and then the first motor group 122 drives the second conveyor belt 121 to drive the first moving seat 123 to move, thereby realizing the transfer of the pipe to be processed on the first conveyor belt 11.

[0041] Please refer to Figure 5 As shown, further, the pneumatic claw 124 includes a mounting plate 1241, a gear 1242, a second cylinder 1243, an active claw plate 1244 and a driven claw plate 1245;

[0042] One end surface of the mounting plate 1241 is connected to the first movable seat 123, and the gear 1242 is rotatably arranged on one end surface of the mounting plate 1241 away from the first movable seat 123; the second cylinder 1243 is arranged on one end surface of the mounting plate 1241 away from the first movable seat 123;

[0043] The active claw plate 1244 is vertically slidably disposed on an end surface of the mounting plate 1241 away from the first movable seat 123 and connected to the movable end of the second cylinder 1243. The active claw plate 1244 is provided with a rack meshing with the gear 1242 on an end surface close to the mounting plate 1241.

[0044] The driven claw plate 1245 is vertically slidably arranged on an end surface of the mounting plate 1241 away from the first moving seat 123 , and an end surface of the driven claw plate 1245 close to the mounting plate 1241 is provided with a rack meshing with the gear 1242 .

[0045] From the above description, it can be seen that during the operation of the pneumatic claw 124, the second cylinder 1243 drives the movable end to move, driving the active claw plate 1244 to move on the mounting plate 1241, and the gear 1242 is driven to rotate through the rack of the active claw plate 1244. Since the rack of the driven claw plate 1245 is meshed with the gear 1242, when the gear 1242 rotates, the driven claw plate 1245 will also move on the mounting plate 1241, thereby completing the clamping and release of the pneumatic claw 124 on the pipe to be processed.

[0046] Please refer to Figure 2 and Figure 4As shown, further, a material storage mechanism 5 is provided at the feeding end of the first conveyor belt 11, and the material storage mechanism 5 includes a cloth belt 51, a tightening wheel 52, a column 53 and a second motor group 54;

[0047] The cloth belt 51 is used to carry the pipe to be processed. One end of the cloth belt 51 is wound around the tightening wheel 52. The tightening wheel 52 is used to tighten the cloth belt. The other end of the cloth belt 51 is connected to the column 53 and the installation height is higher than the tightening wheel 52. A sinking space is enclosed between the column 53 and the tightening wheel 52. When the tightening wheel 52 tightens the cloth belt 51, the pipe to be processed will enter the feeding end of the first conveyor belt 11. When the tightening wheel 52 loosens the cloth belt 51, the pipe to be processed will sink into the sinking space. The second motor group 54 is connected to the tightening wheel 52 for transmission.

[0048] From the above description, it can be known that when the pipe to be processed is fed onto the first conveyor belt 11, the pipe to be processed is placed on the cloth belt 51 and sunk in the sinking space formed between the column 53 and the tightening wheel 52. The second motor group 54 drives the tightening wheel 52 to rotate and reel in the cloth belt 51, so that the cloth belt 51 is gradually straightened. The pipe to be processed will roll into the feed end of the first conveyor belt 11 by itself under the action of gravity.

[0049] Please refer to Figure 2 and Figure 4 As shown, further, a return mechanism 6 is provided above the first conveyor belt 11, and the return mechanism 6 includes a third conveyor belt 61, a third motor group 62, a second moving seat 63, a third cylinder 64 and a return block 65;

[0050] The third motor group 62 is transmission-connected to the driving wheel of the third conveyor belt 61, the second movable seat 63 is connected to the belt of the third conveyor belt 61, the third cylinder 64 is arranged on the second movable seat 63, and the return block 65 is vertically slidably arranged on the second movable seat 63 and connected to the movable end of the third cylinder 64.

[0051] From the above description, it can be known that after the pipe to be processed enters the first conveyor belt 11, the third cylinder 64 drives the movable end to move, so that the return block 65 can be inserted behind the first pipe to be processed, and then the third motor group 62 drives the third conveyor belt 61 to drive the second movable seat 63 to move, and the excess pipe to be processed that enters the feed end of the first conveyor belt 11 behind the first pipe to be processed is pushed back onto the cloth belt 51, thereby ensuring that there is only one pipe to be processed on the first conveyor belt 11, thereby realizing orderly loading one by one.

[0052] Please refer to Figure 1 , Figure 6 and 7As shown, further, a support mechanism 7 is provided at the discharge end of the laser cutting device 3, and the support mechanism 7 includes a base 71, a rotating shaft 72, a transmission gear set 73, a threaded rod 74, a lifting block 75, a bracket 76 and a support plate 77;

[0053] The rotating shaft 72 is rotatably disposed on the base 71, the input gear of the transmission gear set 73 is transmission-connected with the rotating shaft 72, one end of the threaded rod 74 is transmission-connected with the output gear of the transmission gear set 73, and the extending direction of the threaded rod 74 is vertically upward;

[0054] The lifting block 75 is threadedly connected to the threaded rod 74 , the bottom of the bracket 76 is in contact with the lifting block 75 , and the support plate 77 is disposed on the bracket 76 , and the support plate 77 is used to support the pipe extending from the discharge end of the laser cutting device 3 .

[0055] From the above description, it can be seen that before processing the pipe to be processed, it is necessary to rotate the rotating shaft 72 according to the size of the pipe to be processed, so that the transmission gear set 73 drives the threaded rod 74 to rotate, and then the lifting block 75 will move in the vertical direction against the bracket 76, so that the support plate 77 can support the pipe extending from the discharge end of the laser cutting equipment 3, thereby preventing the part of the pipe extending from the discharge end of the laser cutting equipment 3 from swinging during laser cutting.

[0056] Please refer to Figure 7 As shown, further, one side of the support plate 77 is hinged on the bracket 76; a fourth cylinder 711 is hinged on the base 71, and the movable end of the fourth cylinder 711 is hinged to the other side of the support plate 77, and a material receiving bin 712 is provided on the base 71, and when the movable end of the fourth cylinder 711 contracts, the support plate 77 tilts toward the material receiving bin 712.

[0057] From the above description, it can be seen that after the laser cutting equipment 3 cuts the pipe, the processed pipe will fall onto the support plate 77, and then the movable end of the fourth cylinder 711 will shrink, which can make the support plate 77 tilt toward the receiving bin 712, and then the processed pipe will fall into the receiving bin 712 by itself under the action of gravity.

[0058] Please refer to Figure 6 As shown, further, the support plate 77 is hinged with a swing plate 771 at one end close to the laser cutting equipment 3, and the bottom surface of the support plate 77 is hinged with a fifth cylinder 772, and the movable end of the fifth cylinder 772 is hinged to the end of the swing plate 771 away from the support plate 77.

[0059] From the above description, it can be seen that if a shorter pipe needs to be processed, the active end of the fifth cylinder 772 is in a retracted state during the processing, and the swing plate 771 is tilted downward, so that the waste generated by cutting can be prevented from falling on the swing plate 771. When the laser cutting equipment 3 is ready to cut the pipe, the active end of the fifth cylinder 772 will extend to make the swing plate 771 parallel to the support plate 77, so that the processed pipe will fall on the swing plate 771, and then the active end of the fourth cylinder 711 will shrink, so that the support plate 77 together with the swing plate 771 can be tilted toward the material receiving bin 712, and then the processed pipe will fall into the material receiving bin 712 by itself under the action of gravity.

[0069] Please refer to Figure 1 , Figure 6 and 7 As shown, the discharge end of the optical cutting device 3 is provided with a supporting mechanism 7, and the supporting mechanism 7 includes a base 71, a rotating shaft 72, a transmission gear set 73, a threaded rod 74, a lifting block 75, a bracket 76 and a support plate 77; the rotating shaft 72 is rotatably set on the base 71, the input gear of the transmission gear set 73 is transmission connected with the rotating shaft 72, one end of the threaded rod 74 is transmission connected with the output gear of the transmission gear set 73, and the extension direction of the threaded rod 74 is vertically upward; the lifting block 75 is threadedly connected to the threaded rod 74, the bottom of the bracket 76 is abutted against the lifting block 75, and the support plate 77 is set on the bracket 76, and the support plate 77 is used to support the pipe extending from the discharge end of the optical cutting device 3.

And rotate the support wheel 212, so that the notch of the groove 2121 that adapts to the size of the pipe to be processed faces upward; then place multiple pipes to be processed on the cloth belt 51 of the storage mechanism 5, and sink them in the sinking space formed between the column 53 and the tightening wheel 52.

[0073] During the feeding process, the second motor group 54 drives the take-up wheel 52 to rotate and reel in the cloth belt 51, so that the cloth belt 51 is gradually straightened, and the pipe to be processed will roll into the feed end of the first conveyor belt 11 by itself under the action of gravity.

Then the first conveyor belt 11 starts to carry the pipe to be processed to the designated position, and the pneumatic claw 124 of the transfer robot 12 starts to work, and the active end of the second cylinder 1243 extends out, driving the active claw plate 1244 to move vertically downward on the mounting plate 1241, and the gear 1242 is driven to rotate through the rack of the active claw plate 1244. Since the rack of the driven claw plate 1245 is meshed with the gear 1242, when the gear 1242 rotates, the driven claw plate 1245 will also rotate accordingly. It moves vertically upward on the mounting plate 1241 to clamp the pipe to be processed, and then the first motor group 122 drives the second conveyor belt 121 to drive the first movable seat 123 to move toward the propulsion mechanism 2 until the pipe to be processed is moved above the support wheel 212, and then the movable end of the second cylinder 1243 contracts to place the pipe to be processed into the groove 2121 of the support wheel 212, and then the first motor group 122 drives the second conveyor belt 121 to drive the first movable seat 123 to reset.

[0074] During the processing, the movable clamping claw 22 approaches one end of the pipe to be processed along the track 211 and clamps it, and then the movable clamping claw 22 continues to move along the track 211 toward the static clamping claw 23 until the other end of the pipe to be processed is clamped into the static clamping claw 23, and then the movable end of the first cylinder 43 contracts, so that the movable bracket 42 moves with the supporting wheel 212 toward the supporting bracket 41, thereby sinking into the workbench 21. Then the movable clamping claw 22 can continuously push the pipe to be processed, so that the pipe to be processed enters the laser cutting device 3 for laser cutting.

[0075] When a longer pipe is required for processing, the active end of the fifth cylinder 772 is always in a retracted state during the processing, and the swing plate 771 is tilted downward, so that the waste generated by the cutting will not remain on the support mechanism 7. After the laser cutting equipment 3 cuts the pipe, the processed pipe will fall directly onto the support plate 77, and then the active end of the fourth cylinder 711 will shrink, which can make the support plate 77 tilt toward the receiving bin 712, and then the processed pipe will fall into the receiving bin 712 by itself under the action of gravity.

[0076] When a shorter pipe is required for processing, the active end of the fifth cylinder 772 is in a retracted state during the processing, and the swing plate 771 is tilted downward, so that the waste generated by the cutting will not remain on the support mechanism 7. When the laser cutting equipment 3 is ready to cut the pipe, the active end of the fifth cylinder 772 will extend to make the swing plate 771 parallel to the support plate 77, so that the processed pipe will fall on the swing plate 771, and then the active end of the fourth cylinder 711 will shrink, so that the support plate 77 together with the swing plate 771 can be tilted toward the material receiving bin 712, and then the processed pipe will fall into the material receiving bin 712 by itself under the action of gravity.

Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
