[0003] A search revealed that Chinese patent CN223047792U, in the prior art, discloses a "lace fabric slitting device," which includes an equipment box. Inside the equipment box, two motor-controlled cylindrical shafts are rotatably mounted. The upper shaft is concentrically fixed with several cutters, and the lower shaft is concentrically fixed with several bottom cutters. A conveyor belt is installed inside the equipment box. An electric telescopic rod-controlled lifting plate is slidably mounted inside the equipment box, controlling the movement of the upper cylindrical shaft. Two horizontal plates are slidably mounted inside the equipment box, each with several pressure rollers rotatably mounted. The equipment box also contains control components that match the two horizontal plates. The lace fabric is conveyed to the space between the cutters and bottom cutters via the conveyor belt. The electric telescopic rod controls the lifting plate to descend, and the motor drives the cutters to rotate via the cylindrical shafts, cutting the lace fabric into slits.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] Example: Figures 1-5As shown, this embodiment proposes a lace fabric slitting device, including a slitting plate 1, a slitting component 2 for slitting lace fabric is fixedly installed on the top of the slitting plate 1, an adjustment component 3 for adjusting the slitting depth is provided on one side of the slitting component 2, and a feeding component 4 for assisting slitting is rotatably installed on the inner side of the slitting plate 1. The slitting assembly 2 includes a bracket 201 bolted to the top of the slitting plate 1. A connecting rod 202 is slidably installed on the inner side of the bracket 201. An electric push rod 203 is passed through the connecting rod 202. A U-shaped plate 204 is fixedly connected to the bottom of the electric push rod 203. A first motor 205 is fixedly connected to one side of the U-shaped plate 204. A first rotating shaft 206 is installed at the output end of the first motor 205. A cutter disc spacer 207 is bolted to the outer side of the first rotating shaft 206. The cutter disc spacer 207 is located inside the U-shaped plate 204 and is equipped with a disc cutter 208. During the slitting operation, the electric push rod 203 can push the U-shaped plate 204 downward, which in turn drives the first motor 205, the first rotating shaft 206, the cutter disc spacer 207, and the disc cutter 208 downward together, so that the disc cutter 208 contacts the lace fabric for slitting. After the first motor 205 is started, its output end drives the first rotating shaft 206 to rotate, and the first rotating shaft 206 drives the cutter disc spacer 207 to rotate, thereby causing the disc cutter 208 to rotate, achieving precise slitting of the lace fabric. By adjusting the extension and retraction of the electric push rod 203, the slitting depth of the disc cutter 208 can be controlled to meet the slitting needs of lace fabrics of different thicknesses.

[0018] like Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes a second motor 301 bolted to the top of the bracket 201. A lead screw 302 is installed at the output end of the second motor 301. The connecting rod 202 and the lead screw 302 are slidably connected by a slider. A vertical plate 303 is bolted to the bottom of the connecting rod 202. A rotating rod 304 is rotatably installed on the inner side of the vertical plate 303. A pressing roller 305 is provided on the outer side of the rotating rod 304. In actual operation, after the second motor 301 starts, it drives the lead screw 302 to rotate. Since the connecting rod 202 and the lead screw 302 are connected by a slider, the rotation of the lead screw 302 will cause the slider to move up and down along the lead screw 302, thereby driving the connecting rod 202 and the U-shaped plate 204 to move up and down inside the bracket 201. When the U-shaped plate 204 moves down, the pressing roller 305 will move down and press on the lace fabric. The pressing roller 305 can press the lace fabric, keeping the fabric flat during the cutting process and avoiding inaccurate cutting due to fabric wrinkles, thus improving the cutting accuracy and quality. The up and down movement of the pressing roller 305 is controlled by the rotation of the lead screw 302 driven by the second motor 301. The pressing force can be flexibly adjusted according to the lace fabric of different thicknesses and materials, enhancing the adaptability and versatility of the device.

[0019] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the feeding assembly 4 includes a third motor 401 fixedly connected to one side of the slitting plate 1. A second rotating shaft 402 is mounted on the output end of the third motor 401. A third rotating shaft 403 is rotatably mounted on the inner side of the slitting plate 1. The second rotating shaft 402 and the third rotating shaft 403 are connected by a tensioned belt. After the third motor 401 starts, it drives the second rotating shaft 402 to rotate. Since the second rotating shaft 402 and the third rotating shaft 403 are connected by a tensioned belt, the rotation of the second rotating shaft 402 will drive the third rotating shaft 403 to rotate synchronously through the belt, thereby stably and continuously conveying the lace fabric to the slitting position and ensuring the continuity of the slitting process.

[0020] like Figure 2 , Figure 4 Figure 5 As shown, a conveyor belt 5 is provided on the outer side of the second rotating shaft 402 and the third rotating shaft 403, and the conveyor belt 5 is located at the bottom of the pressing roller 305. The conveyor belt 5 effectively increases the friction between the lace fabric and the fabric, preventing the fabric from slipping during the conveying process and ensuring that the fabric can be stably and accurately conveyed to the slitting position.

[0021] like Figure 2 and Figure 3 As shown, the disc cutter 208 is located at the top of the conveyor belt 5, and nine sets of disc cutters 208 are evenly distributed on the outer side of the rotating shaft. These nine sets of disc cutters 208 can simultaneously perform multiple slitting operations on the lace fabric, greatly improving slitting efficiency. When the conveyor belt 5 stably transports the lace fabric to the slitting position, the disc cutters 208 can accurately slit the fabric, ensuring the accuracy and consistency of the slitting.

[0022] like Figure 3 and Figure 4 As shown, the U-shaped plate 204 is located inside the upright plate 303, and ten sets of pressing rollers 305 are symmetrically distributed on both sides of the U-shaped plate 204. The pressing rollers 305 press the lace fabric evenly, keeping the fabric flat during the conveying process. This effectively avoids wrinkles or twisting deformation of the fabric, laying a solid and reliable foundation for subsequent precise slitting operations. After the slitting operation is completed, the pressing rollers 305 continue to play a role, pressing the slitting lace fabric again to prevent it from shifting in subsequent processes and ensuring stable product quality.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a winding device 6 is fixedly installed on one side of the slitting plate 1, and the winding device 6 is located on one side of the conveyor belt 5. The winding device 6 orderly winds up the slit lace fabric, which facilitates subsequent storage, transportation and further processing.

[0024] Working Principle: This utility model provides a lace fabric slitting device. The specific steps are as follows: Step 1: Lay the lace fabric with slits flat on the conveyor belt 5. After the third motor 401 starts, it drives the second rotating shaft 402 to rotate. Since the second rotating shaft 402 and the third rotating shaft 403 are connected by a tensioned belt, the rotation of the second rotating shaft 402 will drive the third rotating shaft 403 to rotate synchronously through the belt, thereby stably and continuously conveying the lace fabric to the slitting position, ensuring the continuity of the slitting process. Continuation; Step 2: After the second motor 301 starts, it drives the lead screw 302 to rotate. Since the connecting rod 202 and the lead screw 302 are connected by a slider, the rotation of the lead screw 302 will cause the slider to move up and down along the lead screw 302, thereby driving the connecting rod 202 and the U-shaped plate 204 to move up and down inside the bracket 201. When the U-shaped plate 204 moves downward, the pressing roller 305 will move downward and press on the lace fabric. The pressing roller 305 can press the lace fabric, so that the fabric... Maintaining flatness during the slitting process avoids inaccurate slitting due to fabric wrinkles, thus improving slitting precision and quality. The second motor 301 drives the lead screw 302 to rotate, controlling the up-and-down movement of the pressing roller 305. The pressing force can be flexibly adjusted according to the thickness and material of the lace fabric, enhancing the adaptability and versatility of the device. Step 3: During the slitting operation, the electric push rod 203 can push the U-shaped plate 204 downwards, thereby driving the first motor 205, the first rotating shaft 206, and the cutter... The disc spacer 207 and the disc cutter 208 move downwards together, so that the disc cutter 208 contacts the lace fabric for cutting. After the first motor 205 is started, its output end drives the first rotating shaft 206 to rotate. The first rotating shaft 206 then drives the cutter disc spacer 207 to rotate, thereby causing the disc cutter 208 to rotate, achieving precise cutting of the lace fabric. By adjusting the extension and retraction of the electric push rod 203, the cutting depth of the disc cutter 208 can be controlled to meet the cutting needs of lace fabrics of different thicknesses.

[0025] All technical features in this embodiment can be freely combined according to actual needs.
