[0004] However, during the use of this utility model, after the cutting mechanism cuts the non-woven fabric, the staff needs to manually place other non-woven fabrics on the conveyor table. At the same time, it is impossible to stack the cut non-woven fabrics, which affects the processing efficiency and cannot meet the production needs. Therefore, a non-woven bag cutting device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a non-woven bag cutting device that facilitates the stacking of non-woven fabrics. It solves the problem that after the cutting mechanism cuts the non-woven fabric, workers need to manually place other non-woven fabrics on the conveyor table, and the cut non-woven fabrics cannot be stacked, which affects processing efficiency and fails to meet production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-woven bag cutting device, comprising a workbench and a gantry frame slidably connected to the top of the workbench, wherein the workbench is provided with an adjustment mechanism capable of adjusting the gantry frame;

[0007] The adjustment mechanism includes a pneumatic clamping device fixedly installed on the side of the gantry frame near the worktable. A threaded rod is rotatably connected inside the worktable, and a threaded sleeve is threadedly connected to the outside of the threaded rod. A drive motor capable of driving the threaded rod is fixedly installed inside the worktable, and a connecting block is fixedly connected between the threaded sleeve and the gantry frame.

[0008] Furthermore, a positioning guide rod is fixedly connected to the side of the workbench away from the threaded rod, and a positioning sleeve is slidably connected to the outside of the positioning guide rod. A connecting rod is fixedly connected between the positioning sleeve and the threaded sleeve.

[0009] Furthermore, the positioning sleeve is fixedly connected to the gantry frame via a connecting block, and the upper surface of the workbench is provided with a movable groove that matches the connecting block.

[0010] Furthermore, a support platform is provided on the top of the workbench, and two support plates are fixedly connected between the support platform and the workbench, with a cutting table fixedly connected between the two support plates.

[0011] Furthermore, a telescopic cylinder extending to the bottom of the support platform is fixedly installed on the top of the support platform, and a cutting blade is fixedly connected to the output end of the telescopic cylinder. A limiting rod penetrating the support platform is fixedly connected to the side of the cutting blade near the telescopic cylinder.

[0012] Furthermore, there are two limiting rods, which are symmetrically distributed on the left and right sides of the telescopic cylinder. The limiting rods are slidably connected to the support platform, and the upper surface of the cutting table is provided with a cutting groove adapted to the cutting blade.

[0013] Furthermore, two mounting plates are fixedly connected to the top of the workbench on the side away from the gantry frame, and a winding drum is rotatably connected between the two mounting plates. A servo motor capable of driving the winding drum is fixedly installed on one side of the right mounting plate.

[0014] Compared with the prior art, this utility model provides a non-woven bag cutting device, which has the following features:

[0015] Beneficial effects:

[0016] 1. This non-woven bag cutting device uses a drive motor to rotate a threaded rod, which in turn moves a threaded sleeve and a connecting block. This allows the threaded sleeve to move the gantry frame back and forth. By using a positioning guide rod and a positioning sleeve, the threaded sleeve can be limited, while improving the stability of the gantry frame movement. By using a pneumatic clamping device, the non-woven fabric can be stretched, thus facilitating the cutting of non-woven fabrics of different lengths.

[0017] 2. This non-woven bag cutting device uses a servo motor to drive the winding drum to rotate, facilitating the winding and unwinding of the non-woven fabric. Combined with an adjustment mechanism, it can stretch the non-woven fabric, keeping it taut and improving the cutting effect. This solves the problem that after the cutting mechanism has cut the non-woven fabric, the operator needs to manually place other non-woven fabrics on the conveyor table, and the cut non-woven fabrics cannot be stacked, which affects processing efficiency and cannot meet production needs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of a nonwoven bag cutting device includes a workbench 1 and a gantry frame 2 slidably connected to the top of the workbench 1. The workbench 1 is characterized by having an adjustment mechanism inside that can adjust the gantry frame 2. The adjustment mechanism includes a pneumatic clamping device 3 fixedly installed on the side of the gantry frame 2 near the workbench 1. A threaded rod 4 is rotatably connected inside the workbench 1. A threaded sleeve 5 is threadedly connected to the outside of the threaded rod 4. A drive motor 6 that can drive the threaded rod 4 is fixedly installed inside the workbench 1. A connecting block is fixedly connected between the threaded sleeve 5 and the gantry frame 2.

[0025] The workbench 1 has a positioning guide rod 7 fixedly connected to the side away from the threaded rod 4 inside. The positioning guide rod 7 is slidably connected to a positioning sleeve 8. A connecting rod 9 is fixedly connected between the positioning sleeve 8 and the threaded sleeve 5. The positioning sleeve 8 is fixedly connected to the gantry frame 2 through a connecting block. The upper surface of the workbench 1 has an active groove that matches the connecting block.

[0026] It should be noted that a controller is fixedly installed on one side of the workbench 1, and a bearing adapted to the threaded rod 4 is fixedly installed inside the workbench 1. The threaded rod 4 is rotated by the drive motor 6, and then the threaded sleeve 5 and the connecting block are displaced by the threaded rod 4, so that the threaded sleeve 5 can drive the gantry 2 to move back and forth. The threaded sleeve 5 can be limited by the positioning guide rod 7 and the positioning sleeve 8, and the stability of the movement of the gantry 2 can be improved. The pneumatic clamping device 3 is set to facilitate the stretching of the non-woven fabric, thereby facilitating the cutting of non-woven fabrics of different lengths.

[0027] In this embodiment, a support platform 10 is provided on the top of the workbench 1. Two support plates 11 are fixedly connected between the support platform 10 and the workbench 1. A cutting table 15 is fixedly connected between the two support plates 11. A telescopic cylinder 12 extending to its bottom is fixedly installed on the top of the support platform 10. A cutting blade 13 is fixedly connected to the output end of the telescopic cylinder 12. A limiting rod 14 penetrating the support platform 10 is fixedly connected to the side of the cutting blade 13 near the telescopic cylinder 12.

[0028] There are two limiting rods 14, which are symmetrically distributed on the left and right sides of the telescopic cylinder 12. The limiting rods 14 are slidably connected to the support platform 10. The upper surface of the cutting table 15 is provided with a cutting groove that is compatible with the cutting blade 13.

[0029] It should be noted that the height of the cutting table 15 is equal to the height of the pneumatic clamping device 3, which facilitates clamping and stretching of the non-woven fabric.

[0030] In this embodiment, two mounting plates 16 are fixedly connected to the top of the workbench 1 on the side away from the gantry 2, and a winding drum 17 is rotatably connected between the two mounting plates 16. A servo motor 18 capable of driving the winding drum 17 is fixedly installed on one side of the right mounting plate 16.

[0031] When the drive motor 6 moves the gantry 2 backward, the servo motor 18 drives the take-up drum 17 to unload the material. When the pneumatic clamping device 3 clamps the nonwoven fabric, the servo motor 18 stops running, thus achieving continuous cutting.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the worker installs the take-up drum 17 containing non-woven fabric between two mounting plates 16. Then, the servo motor 18 is started to drive the take-up drum 17 to rotate, thereby feeding the non-woven fabric. At this time, the worker pulls the non-woven fabric through the cutting blade 13 and the cutting table 15. Then, the non-woven fabric is clamped and fixed by the pneumatic clamping device 3. The drive motor 6 is started to drive the gantry 2 to move forward, and the telescopic cylinder 12 is started to drive the cutting blade 13 to move downward, so that the non-woven fabric can be cut.
