Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically a cardboard box bending and forming mechanism. Background Technology

[0002] Cardboard boxes are containers made of cardboard used for packaging, transporting, and storing goods. They have good rigidity and strength and can widely replace wooden and plastic packaging. They are a green, environmentally friendly, reusable, and cost-effective form of product packaging. A wide variety of products are packaged using corrugated cardboard boxes. During the production process, cardboard boxes often need to be bent and shaped at both ends.

[0003] For small processing workshops, due to economic cost constraints, fully automated processing equipment cannot be used, and only manual bending machines can be used. These tools are usually made of simple metal and can maintain a certain angle and pressure during the bending process; however, in order to ensure that the cardboard does not move during the bending process, this type of manual bending machine requires the use of clamps to fix the cardboard; then the bending component bends the end of the cardboard. The fixing and bending steps need to be performed separately, resulting in poor continuity. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a cardboard box bending and forming mechanism, including a workbench 1, a lifting plate 4 located above the workbench 1 and capable of vertical movement, L-shaped connecting strips 5 fixedly connected to both ends of the lifting plate 4, and bending strips 6 fixedly connected to the other end of the L-shaped connecting strips 5, and multiple sets of pressing components 7 provided at the bottom of the lifting plate 4. When the cardboard 10 is placed on the surface of the workbench 1, the lifting plate 4 is driven to descend, the multiple sets of pressing components 7 fix the cardboard 10, and the bending strips 6 bend the ends of the cardboard 10.

[0026] Each set of pressing components 7 includes at least two telescopic guides 72 fixed to the bottom of the lifting plate 4 and pressure strips 71 fixed to the bottom of multiple sets of telescopic guides 72. A spring 73 is fixedly connected between the top of the pressure strip 71 and the lifting plate 4, and the spring 73 is sleeved on the guide 72. As the lifting plate 4 continues to descend, it will also drive the bending strip 6 to squeeze and bend the end of the cardboard 10.

[0027] The telescopic guide 72 includes a guide sleeve 721 and a guide rod 722 movably inserted inside the guide sleeve 721. The upper end of the guide rod 722 is fixedly connected to the lifting plate 4, and the lower end of the guide sleeve 721 is fixedly connected to the pressure strip 71.

[0028] When the lifting plate 4 is lowered, the pressure strip 71 first contacts the cardboard 10. Under the pressure, the spring 73 is continuously compressed, and the guide sleeve 721 slides on the guide rod 722. At this time, the pressure strip 71 can fix the cardboard 10 to ensure stability when bending.

[0029] In addition, a baffle 2 is fixedly connected to the rear edge of the workbench 1. The baffle 2 is set perpendicular to the workbench 1. When bending the end of the cardboard 10, the cardboard 10 to be bent is placed on the workbench 1, and the rear side wall of the cardboard 10 abuts against the baffle 2.

[0030] Furthermore, it also includes a lifting assembly 3 for driving the lifting plate 4 to move vertically. The lifting assembly 3 includes a horizontally arranged support plate 31 and a motor 32 fixedly installed at the bottom of the support plate 31. A screw 33 is fixedly connected to the output end of the motor 32. A nut block 35 is threaded on the screw 33. The end of the nut block 35 is fixedly connected to the lifting plate 4. Two limit rods 34 are fixedly connected to the support plate 31. The limit rods 34 are movably inserted through the nut block 35.

[0031] Next, the motor 32 is started, driving the screw 33 to rotate. The screw 33 drives the nut block 35 and the lifting plate 4 to descend. The pressure strip 71 first contacts the cardboard 10. At this time, the spring 73 is continuously compressed, so that the pressure strip 71 presses and fixes the cardboard 10. Then, the bending strip 6 will come into contact with the end of the cardboard 10 to achieve the purpose of bending the end of the cardboard 10. This device can fix and bend the cardboard 10 at the same time, with smooth continuity, improving the efficiency of product processing.

[0032] In addition, four rectangularly distributed support legs 8 are fixedly connected to the bottom of the workbench 1, with a crossbeam 9 fixedly connected between two support legs 8, and a support plate 31 fixedly connected to the crossbeam 9.

[0033] The length of the cardboard 10 in the front-to-back direction is less than the length of the bending strip 6 in the front-to-back direction. The contact area between the bending strip 6 and the cardboard 10 will be larger, which can distribute the pressure evenly and avoid excessive local pressure that could cause the cardboard 10 to deform or break.
