Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a cardboard box creasing device for cardboard box production. Background Technology

[0002] Traditional cardboard boxes come in various sizes during production, and creases are applied in different locations on different boxes. A utility model patent (CN 221641915 U) proposes a cardboard box creasing device for cardboard box production. This device uses an electric telescopic rod to extend and lower a pressure plate, which then creases the cardboard box by aligning it with the top edge of a support plate. However, the creasing area lacks a corresponding support plate structure, hindering slow pressing and potentially causing shearing and breakage at the operating location, resulting in poor production quality. Furthermore, it lacks synchronously connected auxiliary positioning components, preventing simultaneous pressing and requiring separate pressing and positioning, leading to low efficiency. Therefore, we propose a cardboard box creasing device for cardboard box production. Utility Model Content

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-5As shown, this utility model is a cardboard creasing device for cardboard box production, including a frame 1 with support legs 11. The support legs 11 are fixedly connected to the bottom of the frame 1. The frame 1 is fixed by the support legs 11 on both sides, and can be connected to a conveying device to transport cardboard for creasing operation. The ends of the frame 1 are provided with hinge seats 12, and the sides of the hinge seats 12 are hinged with support plates 13. The hinged support plates 13 can provide auxiliary support for the ends of the cardboard box, and can be rotated synchronously when pressed down to avoid excessive bending and shearing damage, thus ensuring high safety. The front end of the support plate 13 is provided with an arc-shaped surface 14, and the upper surface of the frame 1 is provided with a U-shaped mounting bracket. 15. An electric telescopic rod 16 is fixedly installed at the upper end of the U-shaped mounting bracket 15. The head of the electric telescopic rod 16 is provided with a horizontal plate 17, and one end of the horizontal plate 17 is provided with an operating plate 18. By extending the electric telescopic rod 16, the horizontal plate 17 can be pushed downward, thereby moving the operating plate 18 downward for convenient operation. A rubber protective strip 19 is fixedly connected to the bottom of the operating plate 18, and a right-angle push rod 2 is fixedly connected to the rear surface of the operating plate 18. During the downward movement of the operating plate 18, the right-angle push rod 2 first pushes the support plate 13 to flip, and then the rubber protective strip 19 at the bottom of the operating plate 18 can push the protruding part of the cardboard to bend. This creates indentations along the end of the frame 1, facilitating operation. An auxiliary positioning component 21 is provided on the lower surface of the horizontal plate 17. The auxiliary positioning component 21 includes a connecting rod 22, a connecting cylinder 23 sleeved with the connecting rod, and an auxiliary pressure plate 24. The auxiliary pressure plate 24 is fixedly connected to the lower end of the connecting cylinder 23, and the upper end of the connecting rod 22 is fixedly connected to the lower surface of the horizontal plate 17. Both the horizontal plate 17 and the auxiliary pressure plate 24 are slidably mounted on the inner side of the U-shaped mounting bracket 15. When the electric telescopic rod 16 pushes the horizontal plate 17 to move, it simultaneously moves the connecting rod 22 downwards, thereby moving the connecting cylinder 23 and the auxiliary pressure plate 24 downwards. The auxiliary pressure plate 24 can first contact the cardboard surface to press and position it. As the horizontal plate 17 continues to move downward, it pushes the connecting rod 22 to slide inside the connecting cylinder 23, thereby avoiding collisions. The larger the bending assistance, the greater the downward movement distance, and the greater the pressing force of the auxiliary pressure plate 24, thus ensuring the stability of the pressing and positioning. This allows for synchronous operation and control, which is efficient and stable. After the creasing process is completed, the electric telescopic rod 16 is controlled to retract, taking the horizontal plate 17 back to its original position. The connecting rod 22 can then take the connecting cylinder 23 and the auxiliary pressure plate 24 upward to release the cardboard, facilitating continued conveying. This is convenient and efficient. Furthermore, a protective rubber pad 25 is fixedly attached to the lower surface of the auxiliary pressure plate 24. The protective rubber pad 25 is located above the frame 1. Connecting the protective rubber pad 25 can protect the surface of the carton and prevent scratches and damage. Furthermore, the lower end of the connecting rod 22 is provided with a push block 26, and a compression spring 27 is fixedly installed on the lower surface of the push block 26; Furthermore, the push block 26 and the compression spring 27 are both slidably installed inside the connecting cylinder 23. The compression spring 27 is pressed against the upper surface of the auxiliary pressure plate 24. The push block 26 and the compression spring 27 are installed through the connecting rod 22, which can push the auxiliary pressure plate 24 downward to first contact the surface of the carton for pressing and positioning. After compressing the compression spring 27, it can continue to push downward to avoid interference and facilitate combination and use. Furthermore, a reset component 3 is provided below the pallet 13. The reset component 3 includes an arc-shaped cylinder 31, an arc-shaped rod 32 slidably connected to the arc-shaped cylinder 31, and a limiting screw 33 threadedly connected to the arc-shaped cylinder. The arc-shaped rod 32 is fixedly connected to the lower surface of the pallet 13, and the arc-shaped cylinder 31 is fixedly connected to the lower surface of the frame 1. Furthermore, the end of the arc-shaped rod 32 is provided with a guide block 34, and a return spring 35 is fixedly connected to one side of the guide block 34. The guide block 34 and the return spring 35 are connected through the arc-shaped rod 32, which can slide inside the arc-shaped cylinder 31, thereby restoring support for the tray 13 and facilitating repeated use. Furthermore, the reset spring 35 and the guide block 34 are both slidably installed inside the arc-shaped cylinder 31, with the guide block 34 located on one side of the limit screw 33; In practical use, the right-angle push rod 2 can push the tray 13 downward to flip it over, thereby providing auxiliary support when bending the cardboard and ensuring safety and stability. Simultaneously, it can slide the arc rod 32 inside the arc cylinder 31, which can also push the return spring 35 through the guide block 34 to compress and avoid interference. When the right-angle push rod 2 is released, the return spring 35 unfolds, which can push the guide block 34 and the arc rod 32 to slide, thereby pushing the tray 13 to flip upward and reset. This can realign the upper surface of the frame 1, which is beneficial for supporting the protruding part of the carton. The guide block 34 can be tightened to the position of the limit screw 33 to prevent the arc rod 32 from coming out, while limiting the upward flipping angle to ensure that the tray 13 is in a horizontal position, avoiding interference and ensuring precision and stability.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
