DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

[0026] Please refer to the attached Figure 1 、 2 As shown, a positionable cloth cutting machine includes a workbench 1, a first positioning device 2 is provided on the workbench 1, the first positioning device 2 includes a slide 201, the slide 201 is provided on both sides of the workbench 1, a first servo motor 202 is provided in the slide 201 on one side, a first screw rod 203 is provided on each of the two output ends of the first servo motor 202, and the end of the first screw rod 203 away from the first servo motor 202 is rotatably connected to the inner wall of the slide 201 through a first bearing seat 206, a slide rod 204 is provided in the slide 201 on the other side, a positioning frame 205 is provided on the first screw rod 203 and the slide rod 204, a lifting device 3 is provided in the positioning frame 205, and a first nut 207 is also provided in the positioning frame 205.

[0027] It should be noted that the workbench 1 is provided with a control panel 101, which is electrically connected to the first servo motor 202, the lifting motor 301, and the second servo motor 402. The control panel 101 can centrally control the first servo motor 202, the lifting motor 301, and the second servo motor 402, thereby facilitating operation for the operator and improving work efficiency.

[0028] It should be noted that when the first servo motor 202 is activated, its two output ends respectively drive the two first screw rods 203 to rotate in different directions. Because one end of the first screw rod 203 is rotatably connected to the inner wall of the slide 201 via the first bearing seat 206, the first screw rod 203 can rotate stably. The positioning frame 205, which is mounted on the first screw rod 203 and the slide rod 204, cooperates with the first screw rod 203 through the first nut 207 inside it. When the first screw rod 203 rotates, the first nut 207 drives the positioning frame 205 to move along the first screw rod 203 and the slide rod 204 within the slide 201 on both sides of the workbench 1, thereby achieving horizontal positioning adjustment.

[0029] Please refer to the attached Figure 3 、 4 As shown, the lifting device 3 includes a lifting motor 301, which is located at the top center of the positioning frame 205. Each of the two output shafts of the lifting motor 301 is connected to a rotating shaft 302. The end of the rotating shaft 302 away from the lifting motor 301 is connected to a first gear 303. A second gear 304 is provided below the first gear 303. The second gear 304 is connected to one end of the lifting screw rod 305. The first gear 303 on the rotating shaft 302 and the second gear 304 on the lifting screw rod 305 are meshed with each other and are transmission connected. The end of the lifting screw rod 305 away from the second gear 304 is rotatably connected to the positioning frame 205 through a lifting bearing seat 306. The two lifting screw rods 305 are sleeved with a second positioning device 4.

[0030] It should be noted that if the second positioning device 4 needs to be raised, the lifting motor 301 is controlled to rotate forward. At this time, the motor output shaft drives the rotating shaft 302 to rotate, and the first gear 303 on the rotating shaft 302 rotates accordingly. Through meshing transmission with the second gear 304, the lifting screw 305 rotates. Since the second positioning device 4 is mounted on the lifting screw 305, and the rotation of the lifting screw 305 is converted into linear motion of the second positioning device 4, the second positioning device 4 will rise along the lifting screw 305. If the second positioning device 4 needs to be lowered, the motor is controlled to rotate in the reverse direction.

[0031] Please refer to the attached Figure 5As shown, the second positioning device 4 includes a slide rail 401, a second servo motor 402 is provided at the center of the slide rail 401, and a second screw rod 403 is connected to each of the two output ends of the second servo motor 402. A positioning block 404 is sleeved on the second screw rod 403, and the end of the second screw rod 403 away from the second servo motor 402 is rotatably connected to the inner wall of the slide rail 401 through a second bearing seat 405. A lifting nut 307 is provided in the slide rail 401, a second nut 406 is provided in the positioning block 404, and a rubber block 407 is connected to the bottom of the positioning block 404.

[0032] It should be noted that the distance between the positioning blocks 404 can be changed according to the cutting requirements. If the positioning block 404 needs to be moved to one side to better fix the fabric or adjust the cutting position, the second servo motor 402 can be started, and the two output ends of the second servo motor 402 drive the two second screw rods 403 to rotate. Since the positioning block 404 is provided with a second nut 406 that cooperates with the second screw rod 403, the positioning block 404 will move along the slide rail 401 under the rotation of the second screw rod 403. When the positioning block 404 is moved to the appropriate position, the rubber block 407 at the bottom can fix the fabric while also protecting the fabric from being scratched. The elasticity of the rubber block 407 can adapt to fabrics of different thicknesses to ensure a good fixing effect.

[0033] The specific operation mode of the utility model is as follows:

[0034] First, start the first servo motor 202 through the control panel 101, and its two output ends respectively drive the two first screw rods 203 to rotate in different directions. The positioning frame 205 mounted on the first screw rod 203 and the slide rod 204 cooperates with the first screw rod 203 through the first nut 207 inside it. As the first screw rod 203 rotates, the first nut 207 drives the positioning frame 206 to move along the first screw rod 203 and the slide rod 204 in the slide groove 201 on both sides of the workbench 1 and adjust to the required horizontal position.

[0035] After determining the height to be adjusted for the second positioning device 4 according to the thickness and cutting requirements of the fabric, the lifting motor 301 is controlled through the control panel 101. If the second positioning device 4 needs to be raised, the lifting motor 301 is controlled to rotate forward, and the output shaft of the lifting motor 301 drives the rotating shaft 302 to rotate, and the first gear 303 on the rotating shaft 302 rotates accordingly, and the lifting screw rod 305 is rotated through the meshing transmission with the second gear 304. Since the second positioning device 4 is sleeved on the lifting screw rod 305, and the rotation of the lifting screw rod 305 will be converted into a linear motion of the second positioning device 4, the second positioning device 4 will rise along the lifting screw rod 305. If the second positioning device 4 needs to be lowered, the motor is controlled to reverse. Similarly, the second positioning device 4 will descend along the lifting screw rod 305.

[0036] After determining the distance between the positioning blocks 404 and the direction of position adjustment based on the cutting requirements, the second servo motor 402 is activated via the control panel 101. The two output terminals of the second servo motor 402 drive the two second screw rods 403 to rotate. Because the positioning blocks 404 are equipped with second nuts 406 that cooperate with the second screw rods 403, the positioning blocks 404 move along the slide rails 401 under the rotation of the second screw rods 403. Once the positioning blocks 404 are in the proper position, the rubber blocks 407 at the bottom secure the fabric while also protecting it from scratches. The elasticity of the rubber blocks 407 allows them to adapt to fabrics of varying thicknesses, ensuring a secure hold.

[0037] After completing the above positioning adjustment, start the cutting function of the cutting machine to cut the fabric.

[0038] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
