In this embodiment, the cutting assembly 5 is a carbon dioxide laser cutting head 51 of the prior art. The laser cutting head 51 is fixedly installed on one side of the transverse sliding assembly 1 through a support frame 52. The relative height between the laser cutting head 51 and the upper end surface of the adsorption assembly 3 is fixed. The adsorption assembly 3 is used to suck the material to be cut flat to prevent the uneven surface of the material from causing unstable power of the laser cutting head 51 on the material. The pressing assembly 4 is used to fix the relative position of the material and the adsorption assembly 3 to prevent the material from shifting under force and improve the cutting quality.

[0027] The horizontal sliding assembly 1 can drive the vertical sliding assembly 2 and the adsorption assembly 3 to slide along the X-axis direction.

The control mode and circuit connection will not be explained in detail in this article. The driving motor 12 is a servo motor in the prior art. The controller controls the forward and reverse rotation of the servo motor to realize the lead screw 13 driving the slider 14 to slide on the bottom plate 11. Thus, the horizontal sliding assembly 1 and the vertical sliding assembly 2 drive the adsorption assembly 3 to displace.

[0028] The adsorption assembly 3 includes a box body 31. The box body 31 is fixedly installed at the upper end of the vertical sliding assembly 2. An adsorption plate 32 is arranged at the upper end of the box body 31. Adsorption holes are evenly distributed on the adsorption plate 32.

And the pressing plate 46 can approach or move away from the adsorption assembly 3 through the linear driver 45. The pressing assembly 4 is used to fix the relative position of the material and the adsorption plate 32. The material to be cut in this embodiment is a plastic nylon woven bag blank. When producing large bulk bags, the bag blank is relatively large. It is necessary to fix the relative position of the bag blank and the adsorption plate 32 through the pressing plate 46 on the pressing assembly 4. To prevent the bag blank from shifting when the horizontal sliding assembly 1 and the vertical sliding assembly 2 move. So as to improve the production quality.

The other end of the connecting rod 48 is connected to a low-pressure plate. The linear actuator 45 is a linear motor of the prior art. The controller can control the output end of the linear motor to drive the pressing plate 46 to approach or move away from the adsorption plate 32. When the linear electric drive drives the pressing plate 46 to approach and press against the adsorption plate 32, the spring 49 can provide a floating space for the pressing plate 46 and the connecting rod 48, so as to reduce the selection requirements of the linear motor, prevent the linear motor from pushing the low-pressure plate into hard contact with the adsorption plate 32, causing equipment damage, reducing the input cost, and improving the service life of the parts.

[0031] As Figure 3 shown, the cross-section of the pressing plate 46 is an L-shaped structure to increase the area where the low-pressure plate presses against the above-mentioned bag blank, and it does not interfere with the cutting path of the laser cutting head 51. In this embodiment, the laser cutting head 51 can cause melting and bonding on multiple cutting surfaces of the plastic nylon woven bag blank, which can effectively prevent the plastic nylon woven bag blank from drawing. One end of the slide rod 42 is provided with a linear actuator 45, and the other end of the slide rod 42 is provided with a baffle 44. The baffle 44 is used to limit the relative position of the slide rod 42. In order to enable the slide rod 42 to slide in the sliding sleeve 43 without relative rotation, the outer contour of the slide rod 42 is a polygonal structure, and the inner circle of the sliding sleeve 43 matches the outer contour of the slide rod 42.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
