Description

Technical Field

[0001] The utility model relates to the technical field of fabric cutting devices, and particularly relates to an automatic cutting device for fabrics. Background Art

[0002] In the field of fabric production and processing, it is often necessary to cut a whole piece of fabric into strips of different widths to meet diverse needs.

[0003] However, there are many deficiencies in the existing fabric cutting technology. Traditional fabric cutting devices usually have difficulty automatically cutting fabrics into strips of different widths according to actual requirements, which leads to cumbersome operations when facing various width requirements. For example, if strips of multiple widths need to be cut, it is often necessary to frequently change the cutting tools, and even use multiple cutting devices of different specifications. This not only consumes a large amount of time and manpower, but also seriously affects work efficiency.

[0004] Moreover, the method of manually adjusting the cutting width not only has difficulty in ensuring accuracy, but also easily causes damage and wrinkles to the fabric during the operation, thus affecting the quality of the strips.

[0005] In summary, due to the inability of existing fabric cutting devices to flexibly cut fabrics into strips of different widths, the efficiency and quality of fabric cutting are restricted. Therefore, it is urgent to develop an automatic cutting device that can cut fabrics into strips of different widths according to requirements. Content of the Utility Model

A unwinding motor 301 is provided on the right outer side of the mounting frame 3, and the output shaft of the unwinding motor 301 is fixedly connected to the right end of the unwinding roller 4; A knife shaft 7 is rotatably installed between the two frames 2. A plurality of mounting rings 8 are movably sleeved on the knife shaft 7 through a tool adjusting mechanism. A slitting cutter disc 9 for slitting the fabric 5 in and out is fixedly sleeved on the mounting ring 8; A mounting groove is provided on the frame 2 on the left side of the knife shaft 7. A rotating motor 6 is fixedly installed in the mounting groove, and the output shaft of the rotating motor 6 is fixedly connected to the left end of the knife shaft 7;

[0024] The tool adjusting mechanism includes a guiding chute 702 provided at the top of the tool shaft 7. A sliding box 14 is fixedly connected to the inner wall of the top of the mounting ring 8. The sliding box 14 is slidably mounted in the guiding chute 702 in the horizontal direction. A positioning component for positioning the mounting ring 8 and the slitting cutter head 9 is further provided on the sliding box 14. A horizontal groove 701 is provided at the bottom of the tool shaft 7. A straight rack 13 is fixedly mounted in the horizontal groove 701. A first stepping motor 11 is fixedly mounted on the inner wall of the bottom of the mounting ring 8. The output end of the first stepping motor 11 is fixedly sleeved with a gear 12, and the gear 12 meshes with the straight rack 13. A first cloth guiding roller 201 and a second cloth guiding roller 202 for guiding and conveying the cloth 5 are respectively rotatably mounted between the two frames 2.

[0025] Among them, the positioning component includes a second stepping motor 141 fixedly mounted in the sliding box 14. The output end of the second stepping motor 141 is fixedly connected with a screw rod 142. The bottom end of the screw rod 142 is threadedly connected with a positioning block 143. The bottom end of the positioning block 143 movably penetrates below the sliding box 14 and abuts against and is in positioning cooperation with the bottom inner wall of the guiding chute 702.

[0026] Among them, a threaded groove 144 is provided at the top of the positioning block 143. The bottom end of the screw rod 142 is arranged in the threaded groove 144 and is threadedly connected with the threaded groove 144. An anti-slip pad 145 is fixedly arranged at the bottom end of the positioning block 143. A through hole is provided on the bottom inner wall of the sliding box 14, and the bottom end of the positioning block 143 and the anti-slip pad 145 both movably penetrate through the through hole. Vertical sliding blocks are arranged on both sides of the positioning block 143, and slide rails are arranged on both inner walls of the sliding box 14, and the vertical sliding blocks are slidably mounted on the slide rails in the vertical direction.

[0027] Among them, a controller 10 is arranged on the front surface of the slitting machine table 1. The controller 10 is electrically connected to the unwinding motor 301, the rotating motor 6, the first stepping motor 11, and the second stepping motor 141 for electrical control.

[0028] Such as Figures 1-4An automatic slitting device for fabrics can automatically adjust the spacing between each slitting cutter disc 9 according to actual needs during the fabric slitting process, so as to slit the fabric into strips of different widths. When in use, the unwinding motor 301 drives the unwinding roller 4 to rotate and unwind the fabric 5, and the fabric 5 is also conveyed by the first fabric guiding roller 201 and the second fabric guiding roller 202. At the same time, the rotating motor 6 drives the cutter shaft 7, the mounting ring 8 and the slitting cutter disc 9 to rotate, and then the fabric can be slit into strips. When it is necessary to adjust the slitting width, first, the second stepping motor 141 drives the screw rod 142 to rotate, so that the positioning block 143 is threadedly driven upward on the screw rod 142 through the thread groove 144. The upward movement of the positioning block 143 also drives the anti-slip pad 145 to move upward, and then the abutting positioning of the positioning block 143 and the anti-slip pad 145 against the guiding chute 702 can be released. Subsequently, the first stepping motor 11 drives the gear 12 to rotate forward or backward. When the gear 12 rotates, it meshes with the straight rack 13 for transmission, and then the gear 12, the first stepping motor 11, the mounting ring 8 and the slitting cutter disc 9 can move left or right. When the slitting cutter disc 9 is moved and adjusted to the required position, the second stepping motor 141 drives the screw rod 142 to rotate reversely, so that the positioning block 143 is threadedly driven downward on the screw rod 142 through the thread groove 144, and the anti-slip pad 145 at the bottom of the positioning block 143 can abut against and position the guiding chute 702.

[0029] Finally, this not only facilitates automatically adjusting the spacing between each slitting cutter disc 9 according to actual needs to slit the fabric into strips of different widths, but also after adjustment, through the abutting positioning of the anti-slip pad 145 at the bottom of the positioning block 143 against the guiding chute 702, it can ensure the stable positioning of the mounting ring 8 and the slitting cutter disc 9 on the cutter shaft 7, ensure stable use after adjustment, and has a simple structure, is convenient for adjustment and use, avoids the trouble of manual adjustment in the past, not only reduces the labor consumption, but also improves the work efficiency. Finally, it can flexibly slit the fabric into strips of different widths, ensuring the efficiency and quality of fabric slitting.
