DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] The utility model discloses a dynamic laser cutting device, which includes a bed 1 and a linear guide pair 21 located above the bed 1. A conveyor belt 2 and a roller 3 are also installed above the bed 1. The outer periphery of the roller 3 contacts the conveyor belt 2 and can tighten the conveyor belt 2. When the roller 3 rotates, it can drive the conveyor belt 2 to move. When the device is used to process a sheet material, the sheet material is placed above the conveyor belt 2, thereby achieving flexible contact between the conveyor belt 2 and the sheet material, which can avoid scratches on the surface of the sheet material.

[0029] like Figure 1 , Figure 2 As shown, roller seats 4 are fixed at both ends above the bed 1, and the rollers 3 are installed in the roller seats 4, wherein a driving motor A5 is installed on one side or both sides of the bed 1, and the output end of the driving motor A5 is connected to one end of the roller 3 through a transmission belt 6, thereby, when the driving motor A5 rotates, it can drive the conveyor belt 2 to move.

[0030] like Figure 1 , Figure 3 As shown, the linear guide rail pair 21 is arranged on both sides of the bed 1 and extends along a first direction, the first direction is consistent with the length direction of the bed 1, and the second direction is perpendicular to the first direction. A dynamic roller group 7 and a laser head moving module 8 are also installed above the bed 1.

[0031] like Figure 4 As shown, the dynamic roller group 7 includes a moving frame 9 and a slide plate A10. The moving frame 9 extends along the second direction, i.e., the width direction of the bed 1, and the two ends of the moving frame 9 are respectively located above the two linear guide rail pairs 21. The moving frame 9 can support the conveyor belt 2. A roller frame 11 is also installed on the moving frame 9, and each moving frame 9 is provided with a plurality of roller frames 11, and the plurality of roller frames 11 are arranged at intervals on the moving frame 9 along the second direction. Figure 4 As shown, the bottom of the roller frame 11 is fixed to the movable frame 9, and the top of the roller frame 11 extends along the first direction. A plurality of rollers are installed on the top of each roller frame 11. The roller frame 11 can increase the supporting area of ​​the dynamic roller group 7 for the conveyor belt 2, thereby improving the stability of the sheet material above the conveyor belt 2.

[0032] The slide plate A10 is installed below the two ends of the moving frame 9, and a driving motor B12 is installed on the slide plate A10. The housing of the driving motor B12 is fixed to the slide plate A10, and a gear is installed on the output end of the driving motor B12 after passing through the slide plate A10. Correspondingly, racks are fixed in the linear guide rails 21 on both sides of the bed 1, and the racks are meshed with the gears at the output end of the driving motor B12. Therefore, when the driving motor B12 rotates, the slide plate A10 can move along the linear guide rails 21 in the first direction, thereby realizing the movement of the dynamic roller group 7.

[0033] The laser head moving module 8 includes a transverse beam 13, a column 14 and a slide plate B15. Figure 3As shown, the transverse beam 13 is located above the conveyor belt 2 and extends along the second. The lower ends of the transverse beam 13 are respectively fixed to the upper ends of the columns 14, and the lower ends of the columns 14 are fixed to the slide B15, and the slide B15 is located above the linear guide pair 21. Specifically, a drive motor C16 is installed on the slide B15, and the housing of the drive motor C16 is fixed to the slide B15. The output end of the drive motor C16 passes through the slide B15 and is installed with a gear. The gear at the output end of the drive motor C16 meshes with the rack in the linear guide pair 21, so that when the drive motor C16 rotates, the laser head moving module 8 can move along the linear guide pair 21 in the first direction.

[0034] like Figure 5 As shown, a laser head 17 is installed on the transverse beam 13, and the laser head 17 can move along the second direction on the transverse beam 13 to achieve cutting of the sheet material. On the other hand, a belt guide mechanism is arranged above the slide B15, and the belt guide mechanism is relatively fixed to the slide B. The belt guide mechanism includes two first guide rollers 18 and two second guide rollers 19 located below the first guide rollers 18. Specifically, a vertical plate is fixed above the slide B, and the ends of the first guide roller 18 and the second guide roller are rotatably mounted on the vertical plate above the slide B. As shown Figure 2 , Figure 6 As shown, a concave cavity can be formed after the conveyor belt 2 passes over the first guide roller 18 and the second guide roller 19. Thus, a cutting seam can be formed between the two first guide rollers 18, and the synchronous movement of the cutting seam and the laser head 17 is achieved. It should be understood that the laser head 17 is located directly above the cutting seam.

[0035] like Figure 6 , Figure 7 As shown, the belt passes through the cavity formed by the first guide roller 18 and the second guide roller 19 and extends in the second direction. A waste collection box 20 is also installed in the cavity, and the opening on the upper side of the waste collection box 20 faces the cutting seam formed by the two first guide rollers 18. In addition, a waste conveyor belt and a flue are also installed in the waste collection box 20.
