[0002] Sofa fabric is a general term or abbreviation for the textile fabrics used to manufacture various sofas. Sofa fabrics often need to be slit before processing. Slitting machines cut strips longitudinally into strips of the required specifications. The base is welded from shaped steel and steel plates and undergoes qualitative treatment. The slitting machine production line mainly consists of: a feeding trolley, an uncoiler, a leveling machine, a slitting machine, a waste edge winding machine, a tensioning machine, a winding machine, and an unloading device.

[0004] However, in actual use, the fabric of the above-mentioned slitting machine will gradually shift due to different pressures during the transmission process. The fabric shift will cause the cutting line to be crooked, making the product unable to meet the quality standards and increasing the scrap rate. In view of this, we propose a fabric slitting machine with a positioning structure. Utility Model Content

[0015] Compared with the prior art, this utility model provides a sofa fabric slitting machine with a positioning structure, which has the following beneficial effects:

[0016] 1. This sofa fabric slitting machine with a positioning structure uses guide block one, guide block two, and an arc-shaped plate. The arc-shaped plate is higher in the middle and lower on both sides, causing the sofa fabric strips to shift towards the middle of the arc-shaped plate. This aligns the sofa fabric strips with the center line of the device, improving the cutting or processing accuracy. The pressure on the sofa fabric strips between guide block one and guide block two is less than the pressure on the sides, allowing the cut sofa fabric strips to shift towards the middle of guide block one and guide block two. This enables the cutting component to more accurately align the cutting edge of the fabric strips, reducing deviation and ensuring that the cut fabric strips move stably along the center line. This facilitates subsequent precise processing and winding, avoids twisting or irregular overlapping of the fabric strips, and improves the winding effect and flatness.

[0017] 2. This sofa fabric slitting machine with a positioning structure extends guide block one and guide block two through the setting of slide bars and extension blocks. The length of guide block one and guide block two can be flexibly adjusted according to the width of the sofa fabric strips to adapt to the needs of different width strips, thereby improving the applicability of the slitting machine.

[0024] like Figure 1-Figure 5 As shown, this utility model provides a technical solution: a sofa fabric slitting machine with a positioning structure, including a support 1, a frame 2 fixedly connected to the top end face of the support 1, a cutting component 3 and a positioning component 4 provided on the side wall of the frame 2, the positioning component 4 including a crossbar 401, a guide block 1 402, a connecting block 403, a guide block 2 404, a slot 405, a mounting bracket 406, and an arc plate 407.

[0025] In one embodiment of this utility model, a crossbar 401 is fixedly connected to the side wall of the frame 2. A guide block 402 is provided on the side wall of the crossbar 401. A connecting block 403 is fixedly connected to the side wall of the guide block 402. A second guide block 404 is provided on the side wall of the crossbar 401. A slot 405 is provided on the side wall of the second guide block 404. The slot 405 is inserted into the connecting block 403. The connecting block 403 is threadedly connected to a bolt. The bolt is threadedly connected to the inner wall of the second guide block 404. The guide block 402 and the second guide block 404 are tightly fixed to the side wall of the crossbar 401 by the bolt. A mounting bracket 406 is fixedly connected to the top end face of the frame 2. An arc plate 407 is fixedly connected to the inner top surface of the mounting bracket 406.

[0026] The cutting assembly 3 includes a first motor 301, which is fixedly connected to the side wall of the frame 2. A rotating shaft 302 is fixedly connected to the output end of the first motor 301. A first cutting blade 303 is disposed on the side wall of the rotating shaft 302. A cutting head 304 is fixedly connected to the side wall of the first cutting blade 303. A plug-in block 305 is fixedly connected to the bottom of the first cutting blade 303. A second cutting blade 306 is disposed on the side wall of the rotating shaft 302. A slot 307 is formed on the top end face of the second cutting blade 306, and the slot 307 connects to the plug-in block. 305 is plugged in, slot 307 is threadedly connected to countersunk bolt 308, plug block 305 is threadedly connected to countersunk bolt 308, motor 2 is fixedly connected to the side wall of frame 2, and take-up roller 6 is fixedly connected to the output end of motor 2. Limit roller 1 7 and limit roller 2 8 are sleeved on the side wall of frame 2. Limit cylinder 9 is sleeved on the side wall of frame 2. Limit roller 1 7 is set between cutting blade 1 303 and guide block 1 402. Limit roller 2 8 is set between arc plate 407 and cutting blade 1 303.

[0027] The curved plate 407 has a higher center and lower sides, which causes the fabric strips to shift towards the center of the curved plate 407, thereby aligning the fabric strips with the center line of the device and improving the accuracy of cutting or processing.

[0028] Adjust the number and spacing of the cutting components 3 according to the required width of the fabric strips to be cut. Then move the positions of guide block 1 402 and guide block 2 404 so that they are positioned between the two sets of cutting components 3. Since the diameter between guide block 1 402 and guide block 2 404 is narrower than the diameter on both sides, the pressure on the fabric strip in the middle of guide block 1 402 and guide block 2 404 is less than the pressure on both sides. This allows the cut fabric strips to shift towards the middle of guide block 1 402 and guide block 2 404, enabling the cutting components 3 to more accurately align with the edge of the fabric strips for cutting, reducing deviation, ensuring that the cut fabric strips move stably along the center line, facilitating subsequent precise processing and winding, avoiding twisting or irregular overlapping of the fabric strips, and improving the winding effect and flatness.

[0029] In addition, the side wall of guide block 402 is provided with a mounting groove 10, which is slidably connected to slide rod 12. An extension block 11 is fixedly connected to the end face of slide rod 12. The arc-shaped surface of guide block 402 is threadedly connected to countersunk bolt 13. Countersunk bolt 13 abuts against the outer wall of slide rod 12, thereby extending guide block 402 and guide block 404. The length of guide block 402 and guide block 404 can be flexibly adjusted according to the width of sofa fabric strips to adapt to the needs of different width fabric strips, thereby improving the applicability of the slitting machine.

[0030] In this invention, during use, the middle of the arc plate 407 is higher and the two sides are lower, causing the fabric strips to shift towards the middle of the arc plate 407. The fabric strips are aligned with the center line of the device. The number and distance between the cutting components 3 are adjusted according to the required width of the fabric strips to be cut. The positions of guide block 1 402 and guide block 2 404 are moved so that guide block 1 402 and guide block 2 404 are located between the two sets of cutting components 3, ensuring that the cut fabric strips move stably along the center line.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
