The mounting plate 203 is located inside and above the U-shaped frame 201 and is a key component connecting the first electric push rod 204 and the cutting knife 212. There are four first electric push rods 204, fixed at the top corners of the U-shaped frame 201, with their bottoms connected to the mounting plate 203. Through the extension and retraction movement of the first electric push rod 204, the vertical position of the mounting plate 203 and the cutting knife 212 below it can be adjusted to adapt to non-woven materials of different thicknesses. The cutting knife 212 is arranged on the left and right sides below the mounting plate 203 and can slide horizontally, allowing the cutting knife 212 to adjust the distance as needed while ensuring stability during cutting.

[0026] Further, the workbench 101 is fixedly connected with support legs 102 at the four corners of the bottom, and mounting grooves 103 are provided on the left and right sides of the workbench 101. Inside the left and right mounting grooves 103, there are respectively rotatably connected unwinding rollers 105 and winding rollers 106. The surfaces of the unwinding rollers 105 and the winding rollers 106 are rotatably connected with the spunlace non-woven fabric body A.

[0027] The support legs 102 are fixedly connected to the bottom corners of the workbench 101, providing additional stability and height adjustment to ensure that the entire device remains stable during operation. The mounting grooves 103 are located on the left and right sides of the workbench 101, providing installation space for the unwinding rollers 105 and the winding rollers 106. The unwinding rollers 105 are responsible for releasing the spunlace non-woven fabric body A to be processed, allowing the non-woven fabric material to be unwound smoothly and at the desired speed onto the workbench 101. The winding rollers 106 are arranged in the right mounting groove 103 and are used to collect non-woven fabric materials that have completed the cutting process, which helps maintain the cleanliness of the work area and prepares the finished or semi-finished products for the next process. The spunlace non-woven fabric body A passes over the workbench 101 from the surface of the unwinding roller 105 to the winding roller 106, forming a continuous working path on which the non-woven fabric can be cut and processed.

[0028] Further, the unwinding rollers 105 and the winding rollers 106 are fixedly connected with rotating rods 104 on their inner walls, and the two rotating rods 104 are respectively rotatably arranged inside the two mounting grooves 103.

[0029] The rotating rods 104 are fixedly connected to the inner walls of the unwinding rollers 105 and the winding rollers 106, and the two rotating rods 104 are respectively rotatably arranged inside the mounting grooves 103 on both sides of the workbench 101, allowing the unwinding rollers 105 and the winding rollers 106 to freely rotate within the mounting grooves 103, thereby achieving smooth unwinding and winding of the spunlace non-woven fabric body A.

[0030] Further, the front end of the left end rotating rod 104 extends to the front side outside the workbench 101 and is fixedly connected with the first motor 107, the rear end of the two rotating rods 104 extends to the rear side outside the workbench 101 and is rotatably connected therewith, the rear end surface of the two rotating rods 104 is fixedly sleeved with the chain wheels 108, and the chain wheels 108 are meshingly connected with the chain 109.

[0031] By starting the first motor 107, the rotation of the unwinding roller 105 can be controlled, and then the unwinding speed of the spunlace non-woven fabric body A is controlled. The rear end of the two rotating rods 104 extends to the rear side outside the workbench 101, and the chain wheels 108 are fixedly sleeved on the surface thereof. The chain wheels 108 are meshingly connected with the chain 109. This chain transmission mode can ensure the synchronous rotation of the unwinding roller 105 and the winding roller 106, maintain the coordination between the two, and avoid problems such as material stretching or folding caused by speed difference.

[0032] Further, the top of the mounting plate 203 is provided with a slot 205, a horizontal bidirectional threaded rod 206 is rotatably connected above the top of the mounting plate 203, a second motor 207 is fixedly connected to the top of one side of the mounting plate 203, and the output shaft of the second motor 207 is fixedly connected with one end of the horizontal bidirectional threaded rod 206.

[0033] The slot 205 is arranged on the top of the mounting plate 203, which provides a horizontal sliding path for the horizontal threaded sleeve 208. The horizontal bidirectional threaded rod 206 is rotatably connected above the top of the mounting plate 203. Its particularity lies in that it adopts a bidirectional threaded design, that is, the screw threads on one side of the threaded rod are opposite to those on the other side. This design allows the horizontal bidirectional threaded rod 206 to drive the two horizontal threaded sleeves 208 to move in opposite directions or towards each other at the same time when it rotates. By starting the second motor 207, the rotation of the horizontal bidirectional threaded rod 206 can be controlled, and then the positions of the two horizontal threaded sleeves 208 can be changed.

[0034] Further, the horizontal limiting rod 209 is fixedly connected to the inside top of the mounting plate 203, the horizontal threaded sleeves 208 are threadedly connected to the left and right sides of the surface of the horizontal bidirectional threaded rod 206 respectively, the two horizontal threaded sleeves 208 penetrate through the slot 205 and are slidably connected with the horizontal limiting rod 209, and the two horizontal threaded sleeves 208 are slidably connected with the inner wall of the slot 205.

[0035] The horizontal limiting rod 209 ensures the stability and linearity of the horizontal threaded sleeves 208 during horizontal movement, avoiding rotation caused by threaded connection. Each horizontal threaded sleeve 208 is connected with a cutting knife 212, so that the horizontal movement of the horizontal threaded sleeves 208 can directly affect the position of the cutting knife 212.

[0036] Further, the bottoms of the two horizontal threaded sleeves 208 are fixedly connected with U-shaped frames 210, the inner walls of the two U-shaped frames 210 are fixedly connected with third motors 211, and the output shafts of the two third motors 211 extend to the outside of the U-shaped frames 210 and are fixedly sleeved with cutting knives 212.

[0037] The U-shaped frames 210 provide mounting platforms for the cutting knives 212 and keep the cutting knives 212 stable during horizontal movement, and the inner walls of each U-shaped frame 210 are fixedly connected with a third motor 211, which is used for directly driving the corresponding cutting knife 212, thereby ensuring the power transmission efficiency and stability during cutting.

[0038] Further, the front and rear ends of the U-shaped frames 201 away from each other are fixedly connected with L-shaped rods 213, the ends of the four L-shaped rods 213 away from the U-shaped frames 201 are fixedly connected with clamping seats 214, the inner walls of the four clamping seats 214 are attached to the bottom surface of the spunlace non-woven fabric body A, the interiors of the four clamping seats 214 are provided with pressing plates 215, the top parts of the four clamping seats 214 are fixedly connected with second electric push rods 216, the bottom telescopic ends of the four second electric push rods 216 extend to the interiors of the clamping seats 214 and are fixedly connected with the top parts of the pressing plates 215, and the bottom parts of the four pressing plates 215 are attached to the top surface of the spunlace non-woven fabric body A.

[0039] The L-shaped rods 213 provide mounting positions for the clamping seats 214 and ensure that the positions of the clamping seats 214 relative to the workbench 101 are fixed, the ends of the four L-shaped rods 213 away from the U-shaped frames 201 are fixedly connected with clamping seats 214, and the inner walls of each clamping seat 214 are attached to the bottom surface of the spunlace non-woven fabric body A, thereby ensuring that the material remains flat during cutting and avoiding displacement or wrinkling. The interiors of the four clamping seats 214 are provided with pressing plates 215, and the pressing plates 215 are used to firmly press the spunlace non-woven fabric body A before cutting, so as to ensure that the material does not move during cutting, thereby improving cutting accuracy. By controlling the extension and retraction of the second electric push rods 216, the pressure of the pressing plates 215 on the spunlace non-woven fabric body A can be adjusted, thereby ensuring that the material can be stably fixed in the case of different thicknesses and hardnesses.

[0040] When the operation starts, the first motor 107 is started to drive the left end rotating rod 104 to rotate, thereby driving the unwinding roller 105 to release the spunlace non-woven fabric body A. Due to the action of the sprocket 108 and the chain 109, the winding roller 106 at the right end also rotates synchronously, the spunlace non-woven fabric body A passes above the workbench 101 from the unwinding roller 105 to the winding roller 106, forming a continuous working path, and in this process, the material is stably conveyed to the cutting area.

[0041] Before cutting, the controller 202 starts the four No. 2 electric push rods 216 to make the pressing plate 215 close to the top surface of the spunlace nonwoven body A, ensuring the stability of the material during the entire cutting process, and the inner wall bottom of the clamping seat 214 is in close contact with the bottom surface of the spunlace nonwoven body A, further ensuring the flatness of the material without displacement.

[0042] According to the position to be cut, the second motor 207 is started to drive the horizontal bidirectional threaded rod 206 to rotate, so that the two horizontal threaded sleeves 208 and the U-shaped frame 210 below them move horizontally along the slot 205, and the cutting knife 212 is accurately positioned to the required cutting position. The No. 1 electric push rod 204 adjusts the height of the mounting plate 203 according to the thickness of the material or the cutting depth requirement, thereby changing the contact angle and pressure between the cutting knife 212 and the material. Once the cutting knife 212 reaches the specified position, the controller 202 starts the corresponding third motor 211, and the output shaft of the third motor 211 drives the cutting knife 212 to rotate, starting to cut the spunlace nonwoven body A. Each cutting knife 212 has an independent motor drive, and the cutting parameters can be adjusted according to the actual needs.

[0043] After cutting is completed, the first motor 107 continues to run, and the winding roller 106 collects the nonwoven fabric that has completed the cutting process, which helps to maintain the neatness of the working area and prepares the finished product or semi-finished product for the next process. After cutting is completed, the controller 202 issues an instruction to make the No. 2 electric push rod 216 retract, loosen the pressing plate 215, and allow the operator to take out the cut material or continue to send the uncut part into the cutting area.

[0044] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
