The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Embodiment 1

[0031] See also Figure 1-Figure 7The present invention provides a technical solution: a cloth laser cutting device, comprising a workbench 1, connecting frames 2 for fixing a mother roll roller 3 and a recycling roller 4 are arranged at both ends of the workbench 1, a material unloading component 5 is arranged on the inner wall of the workbench 1, a cutting component 6 is arranged on the top surface of the workbench 1, and the cutting component 6 comprises an electric slider 603, a transversely arranged guide rail 604 is installed on one side of the outer wall of the electric slider 603, a rodless cylinder 605 is slidably connected to the surface of the guide rail 604, a laser cutting head 607 and a laser measuring head 606 adapted to the laser cutting head 607 are arranged on the bottom surface of the rodless cylinder 605, the guide rail 604 is installed on the surface of the workbench 1 in a sliding manner parallel to the surface of the cloth through the electric slide rail 601 and the electric slider 603, the rodless cylinder 605 is installed on the surface of the electric slider 603 in a sliding manner parallel to the surface of the cloth through the guide rail 604, and there is a gap between the laser measuring head 606 and the laser cutting head 607 and the cloth.

[0032] When in use, first fix the mother roll roller 3 with the cloth to be cut on the connecting frame 2, then fix the recovery roller 4 on another connecting frame 2, and then pass one end of the cloth through the conveying roller 608 and the rodless cylinder 605 and connect it to the recovery roller 4, then start the cutting component 6, and through the sliding of the rodless cylinder 605 on the surface of the guide rail 604 and the sliding of the electric slider 603 on the surface of the electric slide rail 601, the laser measuring head 606 locates the surface of the cloth, and then the laser cutting head 607 cuts the cloth, and the cut cloth will fall onto the surface of the conveyor belt 503, and start the unloading component 5 to convey the new cloth to be cut to the top of the workbench 1, and at the same time the conveyor belt 503 can unload the cut cloth.

[0033] See also Figure 5 As shown in the figure, the surface of the electric slider 603 is provided with an adsorption mechanism, which includes a conveying roller 608 and a suction pipe 610 located inside the conveying roller 608, and both ends of the suction pipe 610 are fixedly connected to the electric slider 603, and the surface of the conveying roller 608 along the outer periphery is provided with a plurality of suction holes 609, and the top surface of the suction pipe 610 is provided with a groove 611 adapted to the suction holes 609, and the side of the electric slider 603 away from the conveying roller 608 is provided with a connecting pipe 612 adapted to the suction pipe 610, and the surface of the electric slider 603 is provided with a support bar 613 adapted to the conveying roller 608, and the conveying roller 608 is installed on the surface of the electric slider 603 by a rotating mechanism in a rotating manner parallel to the surface of the workbench 1.

[0034] When in use, first connect the connecting pipe 612 to the suction fan, then after the cloth passes through the conveying roller 608 and the rodless cylinder 605, the air inside the conveying roller 608 is extracted through the suction pipe 610 to reduce the air pressure inside the conveying roller 608, so that the conveying roller 608 can absorb external air through the suction hole 609. Since the outer wall of the suction pipe 610 is in contact with the inner wall of the conveying roller 608, the conveying roller 608 can only pass through the suction hole 609 directly above the groove 611 when sucking air through the suction hole 609, so that the cloth can be adsorbed on the surface of the conveying roller 608, and the cloth is limited to ensure the stability of the cloth during cutting, and the toxic smoke generated by laser cutting of the cloth can be absorbed into the interior of the conveying roller 608. At the same time, the two groups of support strips 613 symmetrically arranged directly above the conveying roller 608 can ensure the flatness of the cloth on the surface of the conveying roller 608, so as to prevent inaccurate cutting shape caused by uneven cloth.

[0035] See also Figure 3 As shown in the figure, the rotating mechanism includes a rack 602, the surface of the electric slide rail 601 is fixedly connected with the rack 602, the inner wall of the bottom end of the electric slider 603 is provided with a double gear 614 adapted to the rack 602, one end surface of the double gear 614 is meshed with a chain 615, and the two ends of the conveying roller 608 located inside the electric slider 603 are provided with external gear rings 616 adapted to the chain 615.

[0036] When in use, the double gear 614 is engaged with the rack 602 so that the electric slider 603 can drive the double gear 614 to rotate when sliding on the surface of the electric slide rail 601, and the conveying roller 608 is driven to rotate synchronously on the surface of the cloth through the engagement of the chain 615 and the outer gear ring 616, so that when the cutting position of the cloth is changed, the rotation of the conveying roller 608 cooperates with the limitation of the suction hole 609 by the suction pipe 610 so that the suction holes 609 on the surface of the conveying roller 608 can absorb the cloth in sequence as the electric slider 603 moves, preventing the conveying roller 608 from pulling the cloth through the suction holes 609 when the electric slider 603 moves, thereby changing the tension of the cloth.

[0037] See also Figure 6As shown in the figure, tension adjustment mechanisms are provided at both ends of the electric slider 603, and the tension adjustment mechanisms include a connecting column 619 and a roller 622 adapted to the connecting column 619. A limiting groove is provided on the outer periphery of the roller 622 which is on the same horizontal line as the cloth.

The connecting column 619 rotates with the movement of the electric slider 603 through a linkage structure.

[0038] When in use, put the two ends of the cloth into the inside of the limiting grooves on the surface of the roller 622, cooperate with the guide sleeve 627 to limit the pressing ring 624, press the end of the pressing ring 624 facing the cloth downward, and lift the end away from the cloth upward, so that one end of the pressing ring 624 presses the surface of the cloth, thereby ensuring that the tension of the cloth can remain stable, and the roller 622 will rotate synchronously when the electric slider 603 moves. When the roller 622 rotates, the pressing ring 624 is driven to rotate synchronously through the cooperation of the limiting column 625 and the connecting groove 626, and cooperates with the guide sleeve 627 to enable the pressing ring 624 to always press the two ends of the cloth, and the spring 623 can pull the other end of the pressing ring 624 upward, so that the tension of the cloth can always remain stable.

[0039] See also Figure 7 As shown in the figure, the linkage structure includes a transmission gear 618, a transmission gear 618 adapted to the rack 602 is provided at one end of the connecting sleeve 617 close to the electric slide rail 601, a connecting plate 620 is fixedly connected to the outer wall of one end of the connecting column 619 close to the transmission gear 618, and a transmission bar 621 adapted to the transmission gear 618 is provided on the outer wall of one end of the connecting plate 620 close to the transmission gear 618.

[0040] When in use, the electric slider 603 drives the transmission gear 618 to rotate through the meshing of the transmission gear 618 and the rack 602. When rotating, the transmission gear 618 will squeeze the transmission bar 621, thereby pushing the transmission bar 621 to move, and then pushing the connecting disk 620 to rotate, and driving the roller 622 to rotate through the connection between the connecting disk 620 and the connecting column 619.

[0041] See also Figure 1 and Figure 2As shown in the figure, the unloading assembly 5 includes a driving motor 501 and a loading mechanism. A connecting shaft 502 adapted to the driving motor 501 is provided on the inner wall of the workbench 1, and a conveyor belt 503 is attached to the surface of the connecting shaft 502.

[0042] When in use, the cut cloth will fall onto the surface of the conveyor belt 503, and an external power source is connected to start the drive motor 501, and the conveyor belt 503 is driven to rotate through the connecting shaft 502, so that the cut cloth can be unloaded.
