[0002] Cardboard boxes are packaging containers made from paper materials, mainly used to wrap and protect items. The production of packaging boxes requires the use of cardboard bending equipment, which uses mechanical, hydraulic, or pneumatic methods to fold flat cardboard into specific angles to meet the needs of cardboard boxes for wrapping items. This equipment can improve the efficiency of cardboard box production.

[0003] Currently, cardboard bending equipment still has some shortcomings, such as the inconvenience of manually pushing the cardboard.

[0004] To overcome the problem of inconvenient cardboard pushing, a prior art Chinese patent (publication number: CN220681767U) discloses a cardboard box production bending device. Its moving slider drives the electric telescopic rod and the baffle to move, thereby achieving the purpose of adjusting different baffle positions. Through different baffle positions, the automatic bending component can bend the cardboard at different positions. Through a PLC controller and an infrared distance sensor, the infrared distance sensor measures the distance of the baffle, thereby achieving the purpose of automatically adjusting different baffle positions.

[0005] However, the cardboard bending equipment currently in use still has certain shortcomings. The above document uses baffles to block different positions of the cardboard to achieve continuous bending, but the cardboard is not well pressed and fixed during the bending process, and it is easy to tilt during the bending process, which affects the bending effect. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a cardboard bending device for producing cardboard boxes, so as to solve the problems of instability and inconvenience in continuous bending of cardboard boxes mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cardboard bending device for producing cardboard boxes, comprising a conveying assembly, a pressing assembly connected to the top of the conveying assembly, a lifting assembly connected to the bottom of the conveying assembly, and a control panel installed at the front of the conveying assembly.

[0008] The pressing assembly includes a support frame and a hydraulic rod; the lifting assembly includes a support frame, a hydraulic rod, and a top plate; the conveying assembly includes a base, a drive roller, and a driven roller; the hydraulic output end of the pressing assembly is connected to a movable plate; rotating blocks are symmetrically connected to the top of the movable plate; a guide groove is provided inside the movable plate; and a pressing mechanism for improving the bending effect of the cardboard is provided inside the movable plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, such as Figures 1-5The present invention provides the following technical solution to address the problem of unstable cardboard boxes during bending in a bending machine: A pressing mechanism is disclosed, comprising a conveying assembly 1, a pressing assembly 2 connected to the top of the conveying assembly 1, a lifting assembly 3 connected to the bottom of the conveying assembly 1, and a control plate 4 installed at the front of the conveying assembly 1. The pressing assembly 2 includes a support frame and a hydraulic rod, the lifting assembly 3 includes a support frame, a hydraulic rod, and a top plate, the conveying assembly 1 includes a base, a drive roller, and a driven roller, and a movable plate 101 is connected to the hydraulic output end of the pressing assembly 2. A rotating plate 101 is symmetrically connected to the top of the movable plate 101. The movable block 102 and the movable plate 101 have a guide groove 103 inside. The movable plate 101 is equipped with a pressing mechanism to improve the bending effect of the cardboard. The pressing mechanism includes an electric push rod 104 installed inside the guide groove 103. The output end of the electric push rod 104 is connected to a guide block 105. Toothed plates 106 are fixed on both sides of the guide block 105. Both the toothed plates 106 and the guide block 105 slide inside the guide groove 103. A gear 107 is meshed with the top of the toothed plates 106. The gear 107 is installed on the side of the rotating shaft of the rotating block 102, and a pressing plate 108 is fixed on the side of the rotating block 102.

[0028] When using the cardboard bending machine, starting the conveyor assembly 1 moves the cardboard on the surface. Once the cardboard reaches the designated position, the bending point is at the top of the lifting assembly 3. At this point, pressing the pressing assembly 2 presses the movable plate 101 onto the surface of other parts of the cardboard. The stability of the cardboard is improved after being pressed. Then, starting the electric push rod 104 moves the guide block 105. When the guide block 105 moves, it moves the toothed plate 106. When the toothed plate 106 moves, it drives the gear 107 to mesh and rotate. When the gear 107 meshes and rotates, it drives the rotation... When block 102 rotates, it can rotate inside movable plate 101, and gear 107 can rotate inside movable plate 101. When block 102 rotates, it can drive extrusion plate 108 to rotate to the upper surface of cardboard. At this time, extrusion plate 108 and lifting component 3 are located on both sides of the cardboard folding position. Lifting component 3 will hydraulically drive the top plate to extrude the cardboard below. Because the cardboard is pressed by extrusion plate 108, the cardboard will bend. Other parts of the cardboard are pressed by movable plate 101, so the cardboard as a whole will not tilt, ensuring the bending effect.

[0029] Example 2, as follows Figure 1 , Figure 2 and Figure 6The present invention provides the following technical solution: In order to solve the problem that bending equipment is inconvenient for continuous bending and affects the production of cardboard boxes, based on embodiment one, an adsorption mechanism is disclosed: a fixed block 201 is symmetrically fixed on the top of the conveying component 1, an external plate 202 is connected to the inner side of the fixed block 201, and an adsorption mechanism for improving the continuous bending efficiency of cardboard is provided on the inner side of the fixed block 201. The adsorption mechanism includes an air pump installed on the top of the fixed block 201, and a double-ended pipe 203 is connected to the air inlet end of the air pump. The two ports of the double-ended pipe 203 are respectively connected to a connecting pipe 1 205 and a connecting pipe 2 206. A solenoid valve 207 is installed on the side of the connecting pipe 1 205 and the connecting pipe 2 206. Rubber nozzles 204 are symmetrically installed inside the external plate 202 and the extrusion plate 108. The back of the rubber nozzle 204 is connected through to the end of the connecting pipe 2 206 and the connecting pipe 1 205.

[0030] The cardboard needs to be bent in multiple places to form a shape. Therefore, after one side of the cardboard is bent, the air pump and pressing component 2 can be activated. The pressing component 2 will lift the movable plate 101 slightly, stopping the pressure on the cardboard. Then, the air pump can draw in air. The path of the drawn-in air is through the rubber nozzle 204 to the connecting pipe 206 and then to the double-ended pipe 203. At this time, the rubber nozzle 204 will generate suction force, which can hold the cardboard in place. The rubber material of the rubber nozzle 204 increases the airtightness between the cardboard and the nozzle. After the cardboard is held in place, activating the electric actuator 104 again can push the guide block 105 to slide. When the electric actuator 104 is activated, it can drive the rotating block 102 to rotate in the opposite direction. When the rotating block 102 rotates in the opposite direction, it can drive the extrusion plate 108 to rotate in the opposite direction. This allows the cardboard to rotate upwards. When the cardboard rotates to the bottom of the rubber nozzle 204 inside the outer plate 202, the solenoid valve 207 on the side of the connecting pipe 206 will close, while the solenoid valve 207 on the side of the connecting pipe 105 will open. The suction force of the air pump will be transmitted to the rubber nozzle 204 inside the outer plate 202 through the connecting pipe 105. The rubber nozzle 204 of the outer plate 202 will then hold the cardboard in place to prevent it from sagging or falling. Then, the pressing plate 108 will be reset by the electric push rod 104. After being reset, the pressing plate 108 can press the fold on the other side of the cardboard. Restarting the lifting assembly 3 can bend the other side of the cardboard. This method can achieve continuous bending of the cardboard in one operation, improving the efficiency of carton production.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
