The driving source is arranged at one end of the cutting platform 1, and a braking force is applied to the positioning screw 3 and the opposing screw 12, so that the positioning screw 3 drives the cutting head 7 to move and drives two sets of flat pressing components 8 to flat press in opposite directions. Based on the conversion drive control of the driving source, before cutting the cloth piece, the opposing screw 12 can be driven to rotate, and the rotation force The two sets of flattening components 8 are converted into horizontal force to push the two opposite sets of flattening components 8 to move in opposite directions toward the two ends of the cutting platform 1 in a central opposite displacement manner, and the cloth pieces on the cutting platform 1 are flattened and leveled to keep the cloth pieces flat for cutting. Then, when cutting the cloth pieces, the direction-changing drive positioning screw 3 is rotated to convert the rotational force into horizontal force to push the cutting head 7 to move, so that the two sides of the guide rail components can be linked to each other using a set of driving components to improve the braking accuracy, and the three-way displacement precision cutting process of the cutting head 7 can be realized under the linkage displacement of the translation guide rail 5 and the lifting guide rail 6. Specifically:

[0031] See also Figure 2-8 The driving source has a driving end, which includes a brake motor 21 arranged in the middle of the cutting platform 1 bracket.

The meshing transmission of the transmission worm 32 and the transmission worm wheel 31 is used as a driving component to transmit the driving force to the prismatic brake sleeve 30.

[0032] In addition, the driving source includes a spline shaft 25 arranged between the first spline gear sleeve 23 and the second spline gear sleeve 24, a transmission shaft 26 is provided on one side of the spline shaft 25, and a prismatic transmission end 27 is provided at the other end of the transmission shaft 26, a prismatic brake sleeve 30 is slidably connected to the prismatic transmission end 27, and a limiting shaft ring 29 rotatably connected to the brake seat 16 is provided on the outer side of the sleeve of the prismatic brake sleeve 30, and the other end of the prismatic transmission end 27 is connected to an electric push rod 28 fixed to the brake seat 16, and when the prismatic brake sleeve 30 rotates, the prismatic transmission end 27 is driven to rotate, and then the transmission shaft 26 at one end of the prismatic transmission end 27 and the spline shaft 25 are driven to rotate in combination. Due to the sliding rotation characteristics of the prismatic transmission end 27 and the prismatic brake sleeve 30, the spline shaft 25 can be pushed into the first spline gear sleeve 23 and the second spline gear sleeve 24 in sequence by controlling the telescopic braking of the electric push rod 28, so as to form different driving states in an integrated reversing driving manner, wherein:

[0034] A second driving pulley 15 is provided on the brake seat 16 away from the first driving pulley 11, and a second driven pulley 13 opposite to the second driving pulley 15 is provided at one end of the opposing screw rod 12, and the second driven pulley 13 and the second driving pulley 15 are connected to each other through a second transmission belt 14.

The opposing screw rod 12 is provided with two groups of opposing slides 19 along its axial direction. A flattening assembly 8 is arranged on one side of each group of opposing slides 19. During the rotation of the opposing screw rod 12, the rotational thrust is converted into a horizontal thrust, which pushes the opposing slide 19 to slide along its axial direction, and then pushes the flattening assembly 8 to move along the center of the cutting platform 1 to both ends, so as to perform a flattening process on the cloth pieces on the cutting platform 1.

By utilizing the passive meshing transmission between the differential transmission assembly 20 and the transmission rack 18, the opposing lead screw 12 pushes the flat pressing assembly 8 to translate, while driving the differential transmission assembly 20 and the transmission rack 18 to combine transmission, converting the rotational force into a driving force to drive the micro generator 83 to generate electricity. Specifically:

[0037] The differential transmission assembly 20 includes a transmission housing 201, a first differential shaft 202 is provided inside the transmission housing 201, and a second differential shaft 203 is provided inside the transmission housing 201 away from the first differential shaft 202, a transmission gear 204 meshing with the transmission rack 18 is provided at one end of the first differential shaft 202, and a first differential gear 205 is provided on the first differential shaft 202 away from the transmission gear 204, a second differential gear 206 meshing with the first differential gear 205 is provided on the second differential shaft 203, and the second differential shaft 203 is away from the second differential gear The wheel 206 is provided with a third differential gear 207, and the third differential gear 207 is meshed and connected with a driving gear 208 provided on the input shaft of the micro-generator 83. The meshing transmission of the transmission gear 204 and the transmission rack 18 is utilized to accelerate the passive meshing transmission force through the differential of the first differential gear 205, the second differential gear 206, and the third differential gear 207, and transmit it to the driving gear 208. The rapid rotation of the driving gear 208 is utilized to provide rotational force for the micro-generator 83 to generate electricity, so that the power of the micro-generator 83 is transmitted to the electromagnetic magnet 87.

[0038] Please note that Figure 9-10 The flat pressing assembly 8 includes a flat support frame 81, and the flat support frame 81 is provided with a plurality of groups of magnetic magnets 86 arranged along the plate frame direction thereof, and each group of magnetic magnets 86 is provided with a lifting guide rod 84 running through the inside, and one end of the lifting guide rod 84 is provided with an electromagnetic magnet 87 magnetically opposite to the magnetic magnet 86, and the other end of the lifting guide rod 84 is provided with a flat pressing plate 82 of the flat pressing cutting platform 1, and a return spring 85 with a pier seat on the flat pressing plate 82 is provided on the lifting guide rod 84. Both ends of the bracket of the flat support frame 81 are provided with a plurality of groups of magnetic magnets 86 arranged along the plate frame direction, and each group of magnetic magnets 86 is provided with a lifting guide rod 84. A micro-generator 83 is provided to provide electric energy to the electromagnetic magnet 87. When the flattening assembly 8 moves along the cutting platform 1, the micro-generator 83 generates electricity synchronously and transmits electricity to the electromagnetic magnet 87. The electromagnetic magnet 87 and the magnetic magnet 86 are magnetically locked to overcome the pressure of the reset spring 85, and the lifting guide rod 84 is pushed downward, so that the flattening plate 82 is pressed flat on the cutting platform 1, and the cloth pieces on the cutting platform 1 are flattened in a sliding and flat manner to improve the cutting accuracy.

[0039] Also, see Figure 1 The positioning screw 3 is provided with a positioning slide 4 along its axial direction, and a translation guide rail 5 is provided on the positioning slide 4. The translation slide of the translation guide rail 5 is provided with a lifting guide rail 6, and the lifting slide of the lifting guide rail 6 is provided with a cutting head 7. The translation guide rail 5 and the lifting guide rail 6 are both screw slide structures with the same transmission method as the positioning screw 3. The positioning screw 3 pushes the positioning slide 4 to slide along the positioning guide rail 17. Under the integrated drive of the driving source, the driving and braking are more precise, reducing the deviation influence caused by the traditional separate control drive, and the translation guide rail 5 and the lifting guide rail 6 usually only need to be driven by a single driving component, so the variable displacement control of the cutting head 7 is more precise, and the cutting accuracy is higher.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
