[0002] A cutting machine is an automated industrial device primarily used for the precise cutting of sheet materials, completing the segmentation process without the need for molds. Controlled by system software, it cuts materials according to preset parameters and is widely used in electronics manufacturing, garment processing, packaging, and other fields. Flattening is a crucial step in the cutting process. Insufficient or incomplete flattening of fabric leads to inaccurate cutting and material waste. Existing flattening machines use upper and lower rollers for flattening, with a thickness gauge typically placed on the upper roller to adjust the distance between the rollers according to the fabric thickness. However, simply using upper and lower rollers for flattening is only effective for very small wrinkles; the flattening effect is poor for deeper wrinkles.

[0003] In summary, existing technologies suffer from poor flattening effects and the inability to adjust the flattening distance according to the fabric. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, to address the problems of poor flattening effect and inability to adjust the flattening distance according to the fabric in existing technologies, this utility model discloses a fabric flattening device for a cutting machine. It includes side baffles 4, with a main flattening roller 22 positioned between the two side baffles 4. One inner core of the main flattening roller 22 is connected to a first motor, which is located in a motor housing 7 outside the side baffles 4. When the first motor starts, the main flattening roller 22 moves the fabric in the cutting direction. The other side of the main flattening roller 22 is rotatably connected to another side baffle 4, ensuring that it will not detach during rotation. A fixing box 13 is located on the outer side, and a control panel for a PLC control unit is mounted on the fixing box 13. The control panel allows selection of different temperatures corresponding to different fabrics. Through input on the control panel, the PLC control unit can adjust the temperature to prevent excessively high or low temperatures from affecting fabric flattening.

[0023] The main flattening roller 22 has a rotating resistance wire inside its outer ring, which is controlled by a second switch located on the inner core of the main flattening roller 22. Support columns 3 are mounted on the motor housing 7 and the fixed housing 13, and are connected to the top plate 2. An air pump 1 is located above the top plate 2, connected to the pressure plate 16 via a telescopic column 14. A first switch is built into the top plate 2. An aluminum foil heat-insulating layer 15 is located in the middle of the pressure plate 16, and a heating plate 17 is located below the aluminum foil heat-insulating layer 15. The aluminum foil heat-insulating layer 15 prevents the temperature of the heating plate 17 from affecting the normal operation of the air pump 1. The heating plate 17 is controlled by the first switch. The first switch, the second switch, the air pump 1, and the first motor are all connected to a PLC control unit. Control by the PLC control unit avoids errors from manual flattening and ensures the quality of flattening.

[0024] The main spreading roller 22 and the heating plate 17 are of the same length. An air shaft 10 is located in front of the main spreading roller 22, and a fixing rod 12 is located between the main spreading roller 22 and the air shaft 10, below both. The main spreading roller 22, the air shaft 10, and the fixing rod 12 are all inside the side baffle 4. The function of the air shaft 10 is to fix the fabric shaft, and the function of the fixing rod 12 is to initially spread the fabric to ensure the quality of subsequent spreading.

[0025] The side baffle 4 is connected to the bottom of the base plate 9, and four support feet 5 are provided at the four corners of the base plate 9. A first rotating shaft 11 is provided on the outside of the fixing rod 12. A laser measuring instrument 18 is provided on the fixing rod 12 perpendicular to the base plate 9, and the laser measuring instrument 18 is connected to the PLC control unit. The laser measuring instrument 18 can measure the distance between the fabric and the first rotating shaft 11, and the thickness of the fabric can be obtained by simple difference calculation. This is because the use of thickness gauges is affected by temperature. When the heating plate 17 and the main spreading roller 22 are heated, the thickness cannot be measured accurately. Therefore, the use of the laser measuring instrument 18 can make up for this deficiency. The laser measuring instrument 18 transmits the measured data to the PLC control unit, and the PLC control unit controls the air pump 1 to adjust the distance between the heating plate 17 and the main spreading roller 22 to meet the flattening requirements of fabrics of different thicknesses.

[0026] One side of the air shaft 10 is fixedly connected to the stop block 19, and the other side is connected to the spiral column 21. The spiral column 21 is adapted to the fixing nut 8. The fixing rod 12 is fixed inside the side baffle 4 by the fixing nut 8 and the spiral column 21. The stop block 19 is provided with an air inlet and outlet, and a protruding key 20 is provided near the stop block 19. The air shaft 10 is detachable. The spiral column 21 is fixed by the fixing nut 8 to limit the fabric tube on the air shaft 10. The setting of the stop block 19 and the protruding key 20 strengthens the stability of the air shaft 10. When the fabric tube needs to be replaced, the fixing nut 8 is removed, the air is released through the air outlet on the stop block 19, and the protruding key 20 is deflated. Then the air shaft 10 is removed, and the fabric tube is replaced.

[0027] Specific implementation principle: When using this utility model, firstly, the fabric cylinder is placed on the air expansion shaft 10, and air is injected through the air inlet on the stop block 19 to make the convex key 20 protrude, thus fixing the air expansion shaft 10. To ensure the stability of the air expansion shaft 10, the spiral column 21 is fixed a second time by the fixing nut 8. The laser measuring instrument 18 is started to measure the distance from the base plate 9 to the first rotating shaft 11. The fabric is passed through the bottom of the first rotating shaft 11 and connected to the main flattening roller 22 and the conveying device of the cutting machine. The conveying device can be a conveyor belt, etc. The laser measuring instrument 18 measures the distance again, measuring the distance between the base plate 9 and the fabric. After selecting the fabric through the control panel, the PLC control unit controls the air pump 1, the first switch and the second switch to operate, adjusting the flattening distance and flattening temperature. After adjustment, the PLC control unit controls the first motor to operate, performing the flattening operation. The motor box 7 is equipped with a ventilation plate 6 for heat dissipation of the first motor.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
