Description

Technical Field

[0001] The utility model relates to the technical field of packing box production, in particular to a folding device for packing box production. Background Technique

[0002] As the name implies, a packing box is a box used to pack products. Corrugated cardboard is made into a corrugated cardboard box through die-cutting, creasing, nailing or gluing. Corrugated cardboard boxes are the most widely used packaging products, and their usage has always been the first among various packaging products, including calcium plastic corrugated cardboard boxes. For more than half a century, corrugated cardboard boxes have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance.

[0003] In the application document of a folding device for paper packing box processing proposed in the application number 202320876498.2, through the setting of the conveyor belt and the partition rod, the corrugated cardboard box can be effectively conveyed and moved. Then, the vertical creasing rod and the horizontal creasing rod are used to press the creases of the corrugated cardboard box through the electric telescopic rod. Through the setting of the placing box and the pushing rod, the creased corrugated cardboard box can be effectively made to fall downward through the sliding plate, and then recycled and placed through the movement of the pushing rod, which can effectively improve work efficiency.

[0004] Although the above application meets the usage requirements of users to a certain extent, there are still certain defects in the usage process. The specific problems are as follows: directly folding the packing box causes the vertical creasing rod and the horizontal creasing rod to easily come into direct contact with the packing box during the downward movement, which in turn easily leads to the problem of damage to the packing box, and it is also easy to cause the vertical creasing rod and the horizontal creasing rod to get stuck, resulting in the problem of low folding efficiency of the packing box.

Specific embodiments

[0022] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0023] Embodiment: As Figures 1-3 shown, the present utility model provides a technical solution, a folding device for producing packaging boxes, including a conveyor belt 1. Both ends of the top of the conveyor belt 1 are fixedly installed with motor boxes 2. Both ends of the bottom of the motor box 2 are fixedly installed with electric telescopic columns 3. The bottoms of the two electric telescopic columns 3 are connected by a longitudinal crease rod 4, and the bottoms of the other two electric telescopic columns 3 are connected by a transverse crease rod 5;

[0024] A drive motor 6 is fixedly installed on the top of the conveyor belt 1. The output shaft of the drive motor 6 is fixedly connected to a first bidirectional threaded rod 7. Both ends of the outside of the first bidirectional threaded rod 7 are threadedly connected with a moving plate 8. One end of the moving plate 8 is internally slidably connected with a limit column 9. The limit column 9 is fixedly installed on the top of the conveyor belt 1 to facilitate the limitation of the moving plate 8 and ensure the stability of the movement of the moving plate 8. The bottom of the moving plate 8 is installed with a driving rod 10 by screws. A first electric telescopic rod 11 is installed on the top of the conveyor belt 1 by screws. The bottom of the first electric telescopic rod 11 is installed with an adjusting rod 12 by screws. Both the adjusting rod 12 and one end of the pushing rod 14 are provided with an inclination angle to facilitate pushing one end of the packaging box. One end of the adjusting rod 12 is installed with a second electric telescopic rod 13 by screws. One end of the second electric telescopic rod 13 is installed with a pushing rod 14 by screws;

[0025] One end of the top of the conveyor belt 1 is fixedly installed with a fixed rod 16. One end of the fixed rod 16 is rotatably connected with a second double-threaded screw rod 15. Both ends of the outer side of the second double-threaded screw rod 15 are threadedly connected with connecting rods 18. A limiting rod 17 is slidably connected inside the connecting rod 18. The limiting rod 17 is fixedly installed at one end of the fixed rod 16. The bottom of the connecting rod 18 is installed with a limiting frame 19 by screws. A roller 20 is evenly rotatably connected inside the limiting frame 19.

[0026] The operator places the packing box on the conveyor belt 1, turns on the conveyor belt 1 to convey the packaging bag, and then turns on the driving motor 6 to drive the first double-threaded screw rod 7 to rotate. The moving plate 8 is driven to move by the rotating rod of the first double-threaded screw rod 7, and then the driving rod 10 is driven to move, so that the driving rod 10 pushes the lid of the packing box at the top, and then the lid is initially folded. Then the driving motor 6 is turned on to reset the driving rod 10. Then the conveyor belt 1 is turned on to move the packaging line to the bottom of the transverse crease rod 5. The electric telescopic column 3 is turned on to move and drive the transverse crease rod 5 to move to fold the packing box. Then the electric telescopic column 3 is turned on again to reset the transverse crease rod 5. Then the conveyor belt 1 is turned on again to realize the transportation of the packing box. As the packing box is transported, the lid on one side of the packing box first contacts the adjusting rod 12 to initially fold the lid of the packing box on the side. Then the first electric telescopic rod 11 is turned on to raise the adjusting rod 12. After the packing box is transported to one end of the pushing rod 14, the first electric telescopic rod 11 and the second electric telescopic rod 13 are turned on to initially fold the lid at the other end of the packing box. After the initial folding is completed, the packing box is moved to the bottom of the longitudinal crease rod 4, and the electric telescopic column 3 is turned on to drive the longitudinal crease rod 4 to move to realize the folding of the side lid of the packing box, thus completing the folding of the packing box. The packing box can be folded multiple times to ensure the folding effect of the packing box. And through the pre-folding of the packing box, the problem of jamming when the longitudinal crease rod 4 and the transverse crease rod 5 fold the packing box can be prevented.

[0027] And when folding the packing box, the second double-threaded screw rod 15 is rotated to drive the connecting rod 18 and the limiting frame 19 to move, so as to limit both ends of the packing box, and then ensure the stability of the packing box during transportation, so that the packing box can be folded better and the problem of jamming during the folding of the packing box can be avoided.

[0028] Finally, it should be noted that the above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
