It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1

[0029] A carpet cutting device, such as Figures 1 to 7 As shown, it includes a frame 1, on which a lower conveying roller 3, an upper conveying roller 2, a workbench 6, a cutting mechanism, and a material pressing mechanism 5 are sequentially arranged along the traveling direction of the carpet 4, the lower conveying roller 3 is arranged below the front end of the frame 1, the upper conveying roller 2 is arranged above the front end of the frame 1, the workbench 6 is arranged in the middle position of the upper surface of the frame 1, and mounting plates 10 are respectively arranged on the tops of the two rear support columns 18 behind the frame 1, a connecting plate 20 is connected between the two mounting plates 10, and a fixing block 22 is arranged in the middle position of the connecting plate 20;

[0030] The cutting mechanism includes a moving assembly, a telescopic cylinder 9, a cutter assembly 8, and a calibration assembly 7 which are connected in sequence. The moving assembly includes a screw rod 23 which is respectively rotated between a fixed block 22 and two mounting plates 10, a moving motor 11 which drives the screw rod 23 to rotate, and a moving block 12 which is threadedly matched with each screw rod 23. The moving block 12 extends downward, and one side is connected to the telescopic cylinder 9, and the other side is slidably connected to the connecting plate 20. Specifically, a T-shaped block is provided on the connecting plate 20, and a track is provided on the other side of the moving block 12 so that the T-shaped block is slidably arranged in the track. The moving motor 11 is fixed to the mounting plate 10.

[0031] The cutter assembly 8 includes a receiving block 82 connected to the telescopic end of the telescopic cylinder 9, a cutting knife 83 rotatably arranged at the front side of the receiving block 82, and a cutting motor 84 driving the cutting knife 83 to rotate, and the cutting motor 84 is fixed at the rear side of the receiving block 82;

[0032] The calibration assembly 7 includes a connection block 71 disposed on a receiving block 82 close to one side of the workbench 6, a moving plate 73 mounted on the connection block 71, and a laser sensor 75 disposed on the moving plate 73. The laser sensor 75 and the cutting knife 83 are located on the same horizontal line.

[0033] The laser sensor 75 is used to sense the side lines of the carpet pattern. When the carpet deviates during the conveying process, the position of the laser sensor 75 and the cutting knife 83 can be adjusted by the moving assembly. At this time, the laser sensor 75 and the moving motor 11 can be electrically connected through the controller 19. When the laser sensor 75 does not sense the pattern edge line, the controller 19 controls the moving motor 11 to start, drive the screw rod 23 to rotate, so that the moving block 12 moves on the screw rod 23, and then adjusts the position of the laser sensor 75 and the cutting knife 83 until the laser sensor 75 recognizes and senses the carpet pattern edge line, and the moving motor 11 stops working, so that the cutting knife can be automatically calibrated during cutting to avoid cutting deviation, thereby improving cutting quality and efficiency;

[0034] The above operation can also be performed by setting the switch 21 of the mobile motor 11. When the laser sensor cannot sense the edges on both sides of the carpet pattern, manual fine adjustment can be performed through the switch.

[0035] An oblong hole 72 is vertically provided on the connecting block 71, and the rear side of the moving plate 73 is connected to the oblong hole 72 by bolts 76. The height of the moving plate 73 can be adjusted by the cooperation of the oblong hole and the bolt, thereby adjusting the optimal sensing position of the laser sensor 75 from the carpet.

The laser sensor 75 is connected to the moving plate 73 through an adjustment plate 74, and the adjustment plate 74 is connected to the oblong hole 72 through a bolt 76. The cooperation between the longitudinal oblong hole and the bolt can be used for precise adjustment of the initial position of the laser sensor, so that it can be aligned with the edge of the carpet pattern.

[0037] The pressing mechanism 5 includes a lower pressing roller 17 and an upper pressing roller 16 which are rotatably arranged between two rear support columns 18, and the upper surface of the upper pressing roller 16 is flush with the upper surface of the workbench 6 and the upper conveying roller 2, and the upper pressing roller 16 can move in the vertical direction of the rear support column 18 toward the lower pressing roller 17 through a moving mechanism. The moving mechanism includes a slide 14 provided on one side opposite to the two rear support columns 18, a slider 15 slidably connected in the slide 14, and a pressing cylinder 13 arranged on the top of the rear support column 18. The two ends of the upper pressing roller 16 are respectively rotatably arranged on the corresponding slider 15 through a roller shaft, and the piston end of the pressing cylinder 13 moves through the rear support column 18 and extends into the slide 14 to connect with the slider 15. The slider 15 is driven by the pressing cylinder 13 to move toward the lower pressing roller 17 and clamp the carpet, and the driving motor is used to drive the lower pressing roller 17 to rotate, so that the upper pressing roller 17 rotates together, driving the cut carpet to move.

[0038] A “┍”-shaped protective plate 81 is connected to the upper end of the front side of the receiving block 82, and the upper end of the cutting knife 83 extends to the inside of the protective plate 81. The protective plate 81 plays a protective role in installation to prevent the staff from being cut during operation.

[0039] When the utility model is working, first one side of the carpet is pulled to the left side of the lower conveying roller 3, then it bypasses the upper surface of the upper conveying roller and is pulled between the upper pressing roller 16 and the lower pressing roller 17, and then the pressing cylinder 13 is started to drive the slider 15 to move downward in the slide groove 14 and press the carpet tightly so that it can be transmitted during the cutting process; at this time, the position of the cutter assembly 8 and the calibration assembly 7 is adjusted by the switch 21, and then the height of the movable plate 73 is adjusted by the cooperation of the vertical oblong hole and the bolt on the connecting block 71, and then the position of the bolt on the movable plate in the longitudinal oblong hole is adjusted, and then the front and rear position of the laser sensor is adjusted to align it with the edge lines on both sides of the carpet pattern, and finally the laser sensor is located at the best sensing position; then The driving motor 24 is started to drive the lower pressing roller 17 to rotate, thereby causing the upper pressing roller 16 to rotate together to convey the carpet. At the same time, the telescopic cylinder 9 is started to extend to move the cutter assembly 8 and the calibration assembly downward so that the cutting knife 83 can cut the carpet 4. When the carpet deviates during the cutting process, the laser sensor 75 can be controlled by the controller to always track the side lines of the carpet pattern. In this process, the moving motor 11 is controlled to drive the screw rod 23 to rotate, so that the moving block 12 moves along the connecting plate 20 on the screw rod 23, thereby adjusting the position of the laser sensor 75 to always sense the edge of the carpet, so that the cutting knife 83 can cut accurately, avoid cutting deviation, and then improve the cutting quality and yield guarantee.

The positioning mechanisms include a "┍"-shaped fixed baffle 53, a plurality of mounting frames 52 arranged inside the fixed baffle 53, and a pressure roller 51 rotatably arranged in the mounting frame 52. A guide column 54 is connected to the top of the mounting frame 52, and the upper end of the guide column 54 movably extends to the upper end of the fixed baffle 53 and is connected to a limiting block 55. A buffer spring 56 is sleeved on the guide column 54 between the lateral part of the mounting frame 52 and the fixed baffle 53. The pressure roller 51 presses the two sides of the carpet 4, and elastically presses the buffer spring 56, so as to position the carpet when cutting, prevent deviation, and make the cutting position more accurate. In addition, the buffer spring 56 can also provide a certain buffer for the pressure roller 51. When in use, the limiting block 55 can be pulled up to lift the pressure roller 51 to press the two sides of the carpet under the pressure roller 51.
