DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A carton folding mold that is convenient for stably adjusting the folding knife head includes a moving frame 1 and two folding knives 6. The moving frame 1 is also provided with two telescopic rods 2, which are connected to the remaining components by means of the telescopic rods 2.

[0023] A double-headed screw 3 is provided on the movable frame 1 through a driving motor 4, a nut 10 is threadedly sleeved on the double-headed screw 3, a connecting plate 8 is provided on the nut 10 through a synchronization mechanism, a hanging channel 9 is provided on the connecting plate 8, a hanging rod 12 is provided in the hanging channel 9, the end of the hanging rod 12 is connected to the folding knife 6, a vertical groove 13 is provided on the hanging rod 12, a positioning block 14 is provided in the vertical groove 13 through a pressing mechanism, a positioning hole 20 is provided on the connecting plate 8, a limit frame 5 is provided on the movable frame 1, a transverse groove 17 is provided on the connecting plate 8, and an anti-slip block 11 is provided in the transverse groove 17 through an extrusion mechanism.

[0024] The synchronization mechanism includes a synchronization block 7 arranged on the outer wall of the nut 10, a contact groove 18 is provided on the surface of the connecting plate 8 in contact with the nut 10, and a synchronization groove 16 is provided on the inner wall of the contact groove 18. As shown in the figure, multiple synchronization blocks 7 are provided. By replacing the synchronization block 7 entering the synchronization groove 16, the installation position of the folding knife 6 relative to the nut 10 can be achieved.

[0025] The pressing mechanism includes a vertical spring 15 arranged in the pressing groove. The two ends of the vertical spring 15 are elastically connected to the outer wall of the positioning block 14 and the inner wall of the vertical groove 13 respectively. The vertical spring 15 realizes the pressing operation of the positioning block 14 and can squeeze the positioning block 14 into the positioning hole 20.

[0026] The extrusion mechanism includes a transverse spring 19 arranged in the transverse groove 17. The two ends of the transverse spring 19 are elastically connected to the outer wall of the anti-slip block 11 and the inner wall of the transverse groove 17 respectively. The transverse spring 19 realizes the extrusion of the anti-slip block 11 and can squeeze the anti-slip block 11 into the limit frame 5.

[0027] A limit rod is provided in the movable frame 1, which is arranged parallel to the double-headed screw 3. The limit rod slides through the two nuts 10. The limit rod is not drawn in the figure. It realizes the limitation of the nut 10, thereby preventing it from rotating with the double-headed screw 3, and plays a limiting role.

[0028] The vertical cross-section of the hanging channel 9 is T-shaped, and the vertical cross-section of the hanging rod 12 is also T-shaped. The above T-shaped structure allows the hanging rod 12 to only move laterally to complete the installation and disassembly with the hanging channel 9, and has a limiting effect in the vertical direction.

[0029] The reference disclosure (announcement) number of this utility model is CN218615664U, which is specifically "a carton folding mold that is convenient for stable adjustment of the folding knife head". It only improves the equipment components on the movable frame 1. Therefore, in this solution, only the above-mentioned components are described in detail.

[0030] The driving motor 4 can drive the double-headed screw 3 to rotate. When the double-headed screw 3 rotates, the nut 10 installed thereon can move. The movement of the nut 10 can synchronously drive the connecting plate 8 to move. When the connecting plate 8 moves, the folding knife 6 can be driven by the hanging rod 12 to move to complete the spacing adjustment.

[0031] In this solution, the anti-slip block 11 in the limit frame 5 is pressed, and the anti-slip block 11 compresses the transverse spring 19, and then the anti-slip block 11 enters the transverse groove 17 and disengages from the limit frame 5, and then the connection between the connecting plate 8 and other components and the nut 10 is released, so that the connecting plate 8 and other components can be disassembled.

[0032] In this solution, five synchronization blocks 7 are provided on each nut 10. The synchronization blocks 7 entering the synchronization groove 16 can be replaced to realize asymmetric adjustment of the distance between the two folding knives 6. For example, the folding knife 6 on the left is 20 cm away from the center position of the moving frame 1, and the folding knife 6 on the right can be 30 cm away from the center position of the moving frame 1. This design solution can realize asymmetric processing.

[0033] In this solution, after the positioning block 14 in the positioning hole 20 is pushed up and disengaged from the positioning hole 20, the limit of the hanging rod 12 is released, and the hanging rod 12 can be moved horizontally to drive the folding knife 6 and the connecting plate 8 to be disassembled. After disassembly, it is easier to inspect, maintain or replace the folding knife 6.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
