[0049] Combine Figures 1 to 5 As shown, a folding device for a packaging box includes a belt conveyor 1, a frame 2, a clamping assembly 3, a folding assembly 4, a pressing assembly 5 and an adjusting assembly 6.

[0050] The belt conveyor 1 is used to convey packaging boxes; the frame 2 is arranged on both sides of the belt conveyor 1; the clamping assembly 3 is arranged on the frame 2, and the clamping assembly 3 is located above the belt conveyor 1, and is used to clamp and position the packaging boxes; the folding assembly 4 is arranged above the clamping assembly 3, and is used to fold the packaging boxes; the pressing assembly 5 is arranged on one side of the frame 2, and the pressing assembly 5 is located above the belt conveyor 1, and is used to press the packaging boxes; the pressing assembly 5 is installed on the frame 2 through the adjusting assembly 6, and the adjusting assembly 6 is used to adjust the height of the pressing assembly 5.

[0051] Among them, through the coordinated work of the belt conveyor 1, the clamping component 3, the folding component 4 and the pressing component 5, the automated process of folding the packaging box is realized, which reduces manual intervention, reduces labor intensity, and ensures the safety and continuity of the operation. At the same time, an adjustment component 6 is provided between the frame 2 and the pressing component 5, so that under the action of the adjustment component 6, the utility model can flexibly adapt to packaging boxes of different heights and sizes, so as to effectively adjust the pressing component 5 according to actual conditions, and achieve the effect of pressing processing on packaging boxes of different heights and sizes without replacing equipment or making complicated adjustments, thereby greatly improving the efficiency and flexibility of packaging box folding.

[0052] Combine Figure 2 As shown, the adjustment assembly 6 includes: a mounting plate 61, a mounting bracket 63, a threaded rod 65, a first drive motor 66, and a cross bar 67. The mounting plate 61 is provided with a mounting hole 62; the mounting bracket 63 is provided on one side of the mounting plate 61, and a mounting cavity 64 is vertically provided on one side of the mounting bracket 63; the threaded rod 65 is rotatably disposed in the mounting cavity 64, and the top end of the threaded rod 65 passes through the mounting bracket 63 and extends to the outside of the mounting bracket 63; the first drive motor 66 is provided on the upper portion of the mounting bracket 63, and the output end of the first drive motor 66 is connected to the threaded rod 65; the cross bar 67 is provided between the two mounting brackets 63, with both ends of the cross bar 67 respectively embedded in the mounting cavity 64 and both ends of the cross bar 67 respectively sleeved on the threaded rod 65.

[0053] When the height of the pressing assembly 5 needs to be adjusted, the first drive motor 66 is activated to rotate the threaded rod 65. Since both ends of the crossbar 67 are respectively mounted on the threaded rod 65, as the threaded rod 65 rotates, the crossbar 67 moves along the axial direction of the threaded rod 65, thereby driving the pressing assembly 5 up and down to adjust the height of the pressing assembly 5. By controlling the rotation of the threaded rod 65 by the first drive motor 66, the height of the pressing assembly 5 can be precisely adjusted, ensuring that the pressing force is appropriate and the folding effect is not affected by over- or under-pressure. At the same time, it can also achieve the pressing effect of packaging boxes of different heights and sizes.

[0054] To further illustrate, the mounting bracket 63 is L-shaped. The L-shaped structure enables the mounting bracket 63 to vertically mount the threaded rod 65 within a limited space, making full use of vertical space resources and making the entire device more compact.

[0055] Combine Figure 3 As shown, a pressing assembly 5 is provided on one side of the crossbar 67. The pressing assembly 5 comprises a mounting frame 51. A plurality of rollers 52 are rotatably provided on the mounting frame 51 along its length. The mounting frame 51 is a U-shaped structure.

[0056] Among them, by providing multiple rollers 52, multiple contact points can be formed on the packaging box, thereby achieving uniform pressure on the surface of the packaging box, ensuring that the packaging box is not deformed or damaged by excessive local pressure during the folding process. The rollers 52 can automatically adjust the contact angle as the surface of the packaging box changes, adapt to packaging boxes of different shapes and sizes, and improve the versatility and adaptability of the equipment. The use of rollers 52 can reduce the hard impact of direct contact between the pressing component 5 and the packaging box, reducing damage to the packaging box, especially when handling packaging boxes made of thinner or softer materials. The mounting frame 51 is designed to be a U-shaped structure that can not only effectively carry and fix the pressing component 5, but also protect the rollers 52.

[0057] Combine Figure 1 and Figure 5 As shown, the clamping assembly 3 includes: a telescopic cylinder 31 provided on the frame 2, an output end of the telescopic cylinder 31 passes through the frame 2, and is provided with a clamping plate 32.

[0058] Before the clamping action begins, the clamping plate 32 is in its initial position, at which point the package box can be conveyed normally via the belt conveyor. When the package box reaches the predetermined position, the control system sends a signal to the telescopic cylinder 31, which starts to move. The piston rod of the telescopic cylinder 31 extends, pushing the clamping plate 32 to one side of the package box to clamp the package box. The position of the clamping plate 32 can be adjusted according to the width of the package box to ensure that the package box can be stably clamped. The clamping plate 32 stably fixes the package box in the predetermined position to prevent displacement or offset during the subsequent folding process. When the folding assembly completes the folding process of the package box, the control system sends a signal to the telescopic cylinder 31 again, causing its piston rod to retract, and the clamping plate 32 returns to its initial position, releasing the package box. After the package box is released, it can continue to be transported forward via the belt conveyor to complete the subsequent processing flow.

[0059] Further explanation, the clamping plate 32 is made of rubber. Rubber has good flexibility and elasticity, which can reduce the hard collision between the clamping plate 32 and the packaging box, avoiding scratches or damage to the surface of the packaging box, which is especially important for packaging materials with fragile or sensitive surfaces.

[0060] Combine Figure 5 As shown, the clamping plate 32 is provided with a plurality of rubber bumps 33. The rubber bumps 33 can significantly increase the contact area between the clamping plate 32 and the packaging box, thereby increasing the friction and ensuring that the packaging box can be more firmly fixed in the predetermined position during the clamping process, avoiding the folding effect affected by sliding or movement.

[0061] Combine Figure 1 and Figure 4 As shown, the folding assembly 4 includes: a second drive motor 41, a bidirectional screw rod 42, a slider 43, a bracket 44, a pressure plate 45, a pressure roller 46, and a connecting rod 47. The second drive motor 41 is arranged on one side of the frame 2. The output end of the second drive motor 41 passes through the frame 2 and is connected to the bidirectional screw rod 42, which is rotatably arranged on the frame 2; the slider 43 is sleeved on both ends of the bidirectional screw rod 42; the bracket 44 is arranged on the frame 2 and is located on one side of the slider 43; the pressure plate 45 is rotatably arranged at the bottom of the bracket 44; the pressure roller 46 is rotatably arranged at the bottom of the pressure plate 45; one end of the connecting rod 47 is hinged to the slider 43, and the other end is hinged to the pressure plate 45.

[0062] Before the folding operation begins, the pressure plate 45 and pressure roller 46 are in their initial positions, waiting for the box to enter the folding area. When the box reaches the predetermined position, the control system activates the second drive motor 41, causing the motor's output to begin rotating. The output of the second drive motor 41 is connected to the bidirectional screw 42 via a coupling or other transmission method, causing the bidirectional screw 42 to begin rotating. A slider 43 is mounted on the bidirectional screw 42. As the screw 42 rotates, the slider 43 moves along the screw 42. Because the threads at the ends of the screw 42 have opposite directions, the slider 43 moves toward or away from the center, achieving synchronized and symmetrical movement. A connecting rod 47 is hinged at one end to the slider 43 and at the other end to the pressure plate 45. As the slider 43 moves, the connecting rod 47 pushes the pressure plate 45 to rotate, causing the pressure roller 46 to gradually move toward or away from the box. As the slider 43 continues to move, the pressure roller 46 applies pressure to the box, causing it to fold along the predetermined path. The coordinated action of the pressure plate 45 and pressure roller 46 ensures smooth folding of the box. When the packaging box is folded, the control system controls the second drive motor 41 to move in the opposite direction, the slider 43 returns to the initial position, and the pressing plate 45 and the pressing wheel 46 are also reset, waiting for the arrival of the next packaging box.

[0063] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
