[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Embodiment 1

[0026] like Figure 1 and Figure 2 As shown, the traceless correction device for flexible materials includes a frame 1 and a grabbing clamp 2, wherein the grabbing clamp 2 is a prior art, and specific reference may be made to a staggered puncture grabbing device disclosed in the Chinese Patent Library (application number: 202320770687.1), and in actual use, the grabbing clamp 2 is adaptively adjusted according to different setting positions.

[0027] Specifically,

[0028] The frame 1 is provided with horizontal beams 3, and there are at least three beams 3 arranged in parallel along the width direction of the beams 3, and a row of grabbing fixtures 2 arranged at intervals along the length direction of the beams 3 is provided under each beam 3. In the actual product, the number of beams 3 is 4, and naturally the number of beams 3 can also be set to 3, 5, etc. according to different sizes of workpieces.

[0029] Among them, the two beams 3 at the head and tail are both slidably arranged on the frame 1 along the width direction of the beam 3, and the frame 1 is provided with a driving mechanism for driving the two beams 3 at the head and tail to move closer to or away from each other; both ends of the remaining beams 3 are fixedly connected to the frame 1. Further explanation, power components are arranged at both ends of each beam 3; on the same beam 3, the two power components are respectively used to drive the two grasping clamps 2 at the head and tail to translate along the length direction of the beam 3, so that the correction device can pull the flexible material strongly all around, and obtain a better traceless correction effect, and at this time, the remaining grasping clamps 2 are directly arranged on the corresponding beam 3.

[0030] The two cross beams 3 at the head and tail are driven by a driving mechanism to make the corresponding two rows of grabbing clamps 2 move closer to or away from each other as a whole to perform a correction action. In this way, the power source for driving the grabbing clamps 2 can be effectively reduced in actual design, making the structure of the entire correction equipment simpler, with the advantages of simple structure, stable operation and low cost.

[0031] In this embodiment,

[0032] like Figure 2 and Figure 3 As shown, the driving mechanism includes a horizontally arranged long lead screw 4 and a driving motor 5 for driving the long lead screw 4 to rotate. The length of the long lead screw 4 extends along the width direction of the cross beam 3, and both ends of the long lead screw 4 are rotatably arranged on the frame 1. The threads at both ends of the long lead screw 4 are opposite, and nuts 6 are installed at both ends of the long lead screw 4, and the two nuts 6 are respectively fixed to the two cross beams 3 at the head and tail. In this way, only one driving motor 5 and one long lead screw 4 are used to achieve the head and tail cross beams 3 to approach or move away from each other, which not only has stable operation, but also can further simplify the structure.

[0033] To further explain, the drive motor 5 is arranged on one side of the long lead screw 4, and the drive motor 5 is connected to the middle part of the long lead screw 4 through a transmission structure, so that the drive motor 5 drives the long lead screw 4 to rotate smoothly.

[0034] The transmission structure is a belt transmission structure or a gear transmission structure, which has the advantages of simple structure, stable operation, etc. The preferred transmission structure is a belt transmission structure to achieve flexible transmission.

[0035] The specific structure of the long lead screw 4 is as follows: the long lead screw 4 is composed of a coupling 4a and two short lead screws 4b arranged side by side, and the threads on the two short lead screws 4b are opposite. The ends of the two short lead screws 4b that are far away from each other are rotatably arranged on the frame 1 through a bearing 1, and the adjacent ends of the two short lead screws 4b are connected through a coupling 4a, and the above-mentioned transmission structure connects one of the short lead screws 4b. The long lead screw 4 adopts a split structure, which is convenient for design and processing. Further explanation, the end of one of the short lead screws 4b close to the other short lead screw 4b is rotatably arranged on the frame 1 through a bearing 2 7, and the bearing 2 7 is between the transmission structure and the coupling 4a, so that the long lead screw 4 as a whole can run more smoothly and improve the working stability of the equipment.

[0036] like Figure 2 As shown, the two beams 3 at the head and tail are slidably connected to the frame 1 through the guide rail slider group, so that the two beams 3 slide more smoothly. Among them, the guide rail slider group is an existing product and will not be introduced in detail here. Naturally, the two beams 3 at the head and tail are slidably connected to the frame 1 through the slide groove guide block group.

[0037] like Figure 2 and Figure 4 As shown, the power component includes a screw motor 8 and a base 9 slidably arranged on the beam 3 along the length direction of the beam 3, a nut 2 matched with the screw motor 8 is fixed on the base 9, and the two grabbing fixtures 2 at the head and tail of the same beam 3 are both installed on the corresponding base 9. Among them, the screw motor 8 is an existing product and can be directly purchased on the market. Embodiment 2
