[0015] like Figure 1-Figure 3 As shown, a feeding automatic deviation correction structure of a die-cutting machine includes a frame 1 and a mounting seat 2 arranged on both sides of the top surface of the frame 1, and an upper clamping roller 3, a lower clamping roller 4 and a guide roller 5 are arranged between the mounting seats 2 in parallel, the upper clamping roller 3 is arranged above the lower clamping roller 4, and the guide roller 5 is arranged on the side of the line connecting the upper clamping roller 3 and the lower clamping roller 4. The upper clamping roller 3 and the lower clamping roller 4 initially clamp and adjust the material, and then the guide roller 5 pulls and opens it. In this embodiment, the horizontal height of the guide roller 5 is higher than the clamping point of the upper clamping roller 3 and the lower clamping roller 4, which is conducive to the guiding and tensioning effect of the guide roller 5. It can be set on this side of the guide roller 5 alone, or it can be set with an auxiliary roller 8 as in this embodiment. It also includes a camera assembly 17 that outputs a deviation correction control signal. The camera gives a signal to the servo motor. The servo motor drives the ball screw through a belt. The ball screw is connected to a shaft. Two baffles are designed on the shaft. The baffle clamps the paper and moves left and right to achieve a deviation correction effect. See below for details.

[0016] A driving mechanism for driving the guide roller 5 to rotate is provided on one side of the mounting seat 2, and a connecting seat 6 connected to each other is provided between the upper clamping roller 3, the lower clamping roller 4 and the guide roller 5. A limiting plate 7 is sleeved on the guide roller 5, and the limiting plate 7 is blocked and limited with the connecting seat 6 in the axial direction of the guide roller 5. The connecting seat 6 strengthens the tightness of the connection between the roller shafts and is also conducive to maintaining the preset tightness. The setting of the limiting plate 7 prevents the deviation of the material during the conveying process, and also prevents the material from being too close to the edge of the roller shaft and being involved in other mechanisms.

[0017] It also includes an auxiliary roller 8 that cooperates with the guide roller 5 to clamp, and a coupling seat 2 9 is provided between the lower clamping roller 4, the auxiliary roller 8 and the guide roller 5. The auxiliary roller 8 is more conducive to tensioning the material in the space between the upper clamping roller 3 and the guide roller 5, and the coupling seat 2 9 is provided to strengthen the tightness of the connection between the auxiliary roller 8 and other roller shafts. It should be pointed out that in this embodiment, the lower clamping roller 4 and the guide roller 5 are not directly connected to the mounting seat 2, but are connected through the coupling seat 1 6 or the coupling seat 2 9, and the relative independence is more conducive to stable operation and maintenance.

[0018] The upper clamping roller 3 is provided with a limiting sleeve 10 for limiting the axial movement of the coupling seat 6, thereby enhancing the positioning stability of the coupling seat 6. The limiting sleeve 10 is a cylindrical structure, and one end of the limiting sleeve 10 is distributed in a step shape, and the limiting sleeve 10 is nested with the coupling seat 6. This structure is easy to produce and process, and is quick to install. It can generate resistance by its own weight alone, but it is by no means limited to this.

[0019] The driving mechanism includes a transmission belt 11, an upper transmission wheel 12, a lower transmission wheel 13, a tension wheel 14 and a motor 15. The upper transmission wheel 12 is assembled in linkage with the guide roller 5. The upper transmission wheel 12, the tension wheel 14 and the lower transmission wheel 13 are assembled in linkage with the transmission belt 11. The transmission belt 11 is arranged on one side of the line connecting the upper transmission wheel 12 and the lower transmission wheel 13. This is a form of transmission structure. The synchronous belt transmission is stable and reliable, reducing the influence of factors such as vibration during operation and reducing polarization interference on material transportation. The bottom of the limit plate 7 has an inclined extension plate 16, which is extended to avoid the stretching of the material when it is sent out to affect the correction.

[0020] The guide roller 5 is a ball screw, and the servo motor drives the ball screw to correct the deviation through a synchronous belt. The deviation is corrected in real time according to the printed pattern. This method is more practical and accurate.
