[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a cutting machine with a roll material conveying device. The cutting machine with a roll material conveying device includes a frame 10 and a conveying device 20, a positioning device 30 and a cutting device 40 disposed on the frame 10. The cutting device 40 is disposed on the rear side of the conveying device 20. There are two positioning devices 30, which are disposed on the front and rear sides of the cutting device 40.

[0022] The conveying device 20 includes a feeding roller group 21 and a clamping device 22. The feeding roller group 21 includes a discharge roller 211, a conveying roller 212, an adjusting device 213, a clamping roller group 214, and a hot pressing roller group 215 arranged sequentially from front to back. The flexible circuit board substrate is rolled onto the discharge roller 211. The adjusting device 213 includes two mounting plates 216 and an adjusting assembly disposed between the two mounting plates 216. The adjusting assembly is mounted on the corresponding side mounting plate 216 via a rotating shaft and can rotate along the mounting plate 216. The adjusting assembly includes two positioning plates 217 and three adjusting rollers 218 disposed inside the two positioning plates 217. The three adjusting rollers 218 are arranged horizontally at intervals. The positioning plates 217 are mounted on the corresponding side mounting plates 216 via a rotating shaft.

[0023] The clamping roller assembly 214 includes two clamping rollers arranged vertically opposite each other, forming a material passage between the two clamping rollers. The hot pressing roller assembly 215 includes two hot pressing rollers arranged vertically opposite each other, forming a passage between the two hot pressing rollers that corresponds horizontally to the material passage of the clamping rollers. In this embodiment, the hot pressing rollers are equipped with a heating device. During conveying, the flexible plate passes from the feeding roller 211 through the conveying roller 212 into the gap between two adjacent adjusting rollers of the adjusting device 213, then through the material passage of the clamping roller assembly 214, and then into the hot pressing roller assembly 215 for hot pressing to improve flatness. The hot pressing rollers not only play a conveying role but also a hot pressing and leveling role. In addition, when the conveyed material belt is too loose, the adjusting device 213 rotates to tighten the material belt, ensuring smooth conveying.

[0024] The frame 10 includes a base 11 and side plates 12 disposed on both sides of the base 11. Two guide rails 13 are disposed on the side plates 12, extending along the conveying direction. The clamping device 22 is mounted on the guide rails 13 at both ends and can move along the guide rails 13. The clamping device 22 includes a mounting frame 221 and several positioning clamps 222 disposed on the front side of the mounting frame 221. Each positioning clamp 222 includes an upper plate 2221, a lower plate 2222, and a drive motor 2223 disposed opposite to each other. The upper plate is mounted on the drive motor 2223, which drives the upper plate 2221 to move up and down. In this embodiment, soft pads are disposed on the bottom surface of the upper plate 2221 and the top surface of the lower plate 2222. The soft pads can be made of silicone.

[0025] In this embodiment, the positioning clip 222 can be multiple small positioning clips (such as...). Figure 2 As shown), during use, they are clamped at both ends and the middle area of ​​the flexible sheet material strip, respectively. It is understood that only one positioning clamp 222 may be provided (e.g., Figure 5 As shown), the lengths of its upper plate 2221 and lower plate 2222 are slightly longer than the width of the flexible sheet material strip. Furthermore, in this embodiment, the guide rail 13 extends from front to back below the rear side of the positioning device 30, below the cutting device 40, below the rear positioning device 30, and extends to its rear side. Additionally, a guide groove is provided on the side of the mounting bracket 221, and the inner end of the positioning clamp 222 is installed in the guide rail and can move along the guide groove for position adjustment.

[0026] The positioning device 30 includes a positioning frame 31, a driving device 32, a moving plate 33, and a base plate 34. The two ends of the positioning frame 31 are mounted on the side plates 12. The driving device 32 is mounted on the positioning frame 31, and the moving plate 33 is movably mounted on the bottom surface of the positioning frame 31. The base plate 34 is located directly below the moving plate 33. The driving device drives the moving plate 33 to move towards the base plate 34 and clamp the material strip. The cutting device 40 includes a fixed frame 41 and a cutter 42 disposed on the bottom surface of the fixed frame 41. The cutter 42 can move up and down to perform cutting processing. Furthermore, a pad (not shown) is provided at the bottom of the fixed frame 41, and the top surface of the pad is flush with the top surface of the base plate 34.

[0027] During operation, the flexible strip is first guided along the conveyor 20 to the rear of the preceding positioning device 30. The clamping device 22 moves forward to the rear of the positioning device 30, clamping the end of the flexible strip. It then moves the flexible strip backward to the required position, ensuring the length behind the cutting device is the required cutting length. At this point, the bottom surface of the flexible strip is level with the top surface of the base plate 34 at the bottom of the positioning device 30 and the top surface of the pad directly below the cutting device 40, with the bottom surface in contact with them. The two positioning devices 30 move downward to clamp and fix the flexible strip. Then, the cutting device 10 drives the cutter downward to cut the strip. After cutting, the cutting device 10 and the subsequent positioning device 40 move upward, and the clamping device 22 moves the cut sheet onto the rear conveyor belt for transport to the next process. Then the clamping device 22 moves forward again, clamping the end of the material strip behind the previous positioning device 30. The previous positioning device 30 moves upward, and the clamping device 22 pulls the material strip backward, repeating this process. In addition, in this embodiment, while the clamping device 22 pulls the material strip, the feeding roller group 21 will rotate actively and feed the material synchronously.

[0028] In summary, this utility model feeds the flexible sheet roll using a conveying device 20, a clamping roller group 214, a hot pressing roller group 215, and an adjusting device 213. The adjusting device 213 prevents the flexible sheet roll from becoming too loose, which could lead to partial folding and indentations. The hot pressing roller group 215 can level the roll while feeding it. Furthermore, the clamping device 22 feeds the roll to the cutting device 40, and positioning devices 30 are installed on the front and rear sides of the cutting device 40 to position the roll. Compared to traditional cutting methods, the cutting operation in this utility model is more stable, produces better cutting results, and has higher work efficiency. This utility model is highly practical and has significant potential for widespread application.

[0029] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
