With the development of automation technology, some automatic folding equipment has emerged. However, existing equipment suffers from problems such as complex structure, difficult debugging, and poor adaptability to different packaging box sizes. Therefore, it is necessary to design and modify intelligent packaging box folding equipment to effectively prevent inconvenience in its use. Utility Model Content

[0013] 2. This utility model, through the arrangement of a third electric cylinder, support plates, limiting rods, tension springs, and clamping plates, allows the extension of the third electric cylinder to bring the support plates on both sides closer together, which in turn brings the limiting rods, tension springs, and clamping plates on both sides closer together, and further brings the pressure detectors and anti-slip pads on both sides closer together until the anti-slip pads are in contact with the packaging box. At this point, the support plates on both sides continue to move closer, causing the tension springs to be stretched, thus applying a clamping force to the packaging box. The pressure detectors can detect the magnitude of the pressure applied by the clamping plates to both sides of the packaging box, preventing damage to the packaging box due to excessive pressure. This application has a control component on the right side of the fixing frame, through which the pressure detector controls the third electric cylinder.

Motor 10, the output end of the first motor 10 is fixedly connected to the actuating frame 9, movable columns 11 are slidably connected to both sides inside the drive box 4, a first positive and negative threaded rod is rotatably connected inside the drive box 4, the first positive and negative threaded rod is threadedly connected to the movable column 11, a dual-axis motor 13 is fixedly connected inside the movable column 11, an adjusting frame 14 is fixedly connected to the output end of the dual-axis motor 13, a second motor 12 is fixedly connected to the right side of the drive box 4, the output end of the second motor 12 is fixedly connected to the first positive and negative threaded rod, and a conveyor 31 is fixedly connected to the top of the base plate 1.

[0021] refer to Figure 1 Both sides of the fixed frame 2 are fixedly connected to a third electric cylinder 15. The output end of the third electric cylinder 15 is fixedly connected to a support plate 16. The inside of the support plate 16 is slidably connected to a limit rod 17. The surface of the limit rod 17 is fixedly connected to a clamping plate 19. The surface of the support plate 16 is fixedly connected to a tension spring 18. The tension spring 18 is fixedly connected to the limit rod 17.

[0022] As a technical optimization of this utility model, by setting up a third electric cylinder 15, a support plate 16, a limiting rod 17, a tension spring 18, and a clamping plate 19, the extension of the third electric cylinder 15 can drive the support plates 16 on both sides to move closer to each other, thereby driving the limiting rods 17, tension springs 18, and clamping plates 19 on both sides to move closer to each other, and then driving the pressure detectors 20 and anti-slip pads 21 on both sides to move closer to each other until the anti-slip pads 21 are in contact with the packaging box. At this time, the support plates 16 on both sides continue to move closer, thereby stretching the tension springs 18. At this time, a clamping force is applied to the packaging box. The pressure detectors 20 can detect the pressure applied by the clamping plates 19 to both sides of the packaging box, avoiding damage to the packaging box due to excessive pressure. This application provides a control component on the right side of the fixing frame 2. The pressure detectors 20 control the third electric cylinder 15 through the control component. The pressure detectors 20 and the control component are common existing technologies, and will not be described in detail in this application.

[0023] refer to Figure 2The top of the drive box 4 is provided with a sliding groove, and movable frames 22 are slidably connected to both sides inside the sliding groove. A fourth electric cylinder 23 is fixedly connected to the surface of the movable frame 22. A pressure plate 24 is fixedly connected to the output end of the fourth electric cylinder 23. Limit blocks 25 are fixedly connected to both sides of the top of the drive box 4. A second positive and negative threaded rod 27 is rotatably connected inside the limit block 25. A third motor 26 is fixedly connected to the right side of the right limit block 25. The output end of the third motor 26 is fixedly connected to the second positive and negative threaded rod 27. The second positive and negative threaded rod 27 is threadedly connected to the movable frame 22.

[0024] As a technical optimization of this utility model, by setting up a sliding groove, movable frame 22, fourth electric cylinder 23, pressure plate 24, limit block 25, second positive and negative threaded rod 27 and third motor 26, the rotation of the third motor 26 drives the rotation of the second positive and negative threaded rod 27, thereby driving the movable frames 22 on both sides to move closer or further away from each other, thereby driving the fourth electric cylinder 23 and pressure plate 24 on both sides to move closer or further away from each other.

[0025] refer to Figure 2 The drive box 4 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 4, while the inner ring of the bearing is fixedly connected to the first positive and negative thread rod.

[0026] As a technical optimization of this utility model, by setting the bearing, the friction between the drive box 4 and the first positive and negative thread rod can be reduced, thereby facilitating the rotation of the first positive and negative thread rod.

[0027] refer to Figure 1 A cylinder 28 is fixedly connected to all four sides of the bottom of the base plate 1. A first threaded rod 29 is threadedly connected inside the cylinder 28. A support pad 30 is fixedly connected to the bottom of the first threaded rod 29.

[0028] As a technical optimization of this utility model, by setting up the cylinder 28, the first threaded rod 29 and the support pad 30, the operator can rotate the first threaded rod 29, thereby driving the first threaded rod 29 and the support pad 30 to move up or down, thereby adjusting the height or level of the base plate 1.

[0029] refer to Figure 3 A pressure detector 20 is fixedly connected to the surface of the clamping plate 19, and an anti-slip pad 21 is fixedly connected to the surface of the pressure detector 20.

[0030] As a technical optimization of this utility model, by setting up the pressure detector 20 and the anti-slip pad 21, the pressure detector 20 can detect the pressure between the anti-slip pad 21 and the packaging box, and the anti-slip pad 21 can improve the stability of the packaging box positioning.

[0031] The working principle and usage process of this utility model are as follows: In use, the operator places the packaging box on top of the conveyor 31, and then adjusts the drive box 4 upwards or downwards according to the height of the packaging box. This, in turn, moves the fixing block 5, the second electric cylinder 6, and the folding frame 7 upwards or downwards, so that the height of the folding frame 7 is slightly higher than the height of the packaging box. The front of the folding frame 7 is arc-shaped, which can push the cover plate on the back of the top of the packaging box to rotate and close towards the front. When the center of the top of the packaging box is aligned with the front of the folding frame 7, the operator starts the first motor 10 to rotate, driving the actuating frame 9 to rotate, which in turn actuates the cover plate on the front side of the top of the packaging box to rotate and close. From the right-hand view, the actuating frame 9 rotates counterclockwise. Then, the conveyor 31 transports the packaging box to the back, causing the folding frame 7 to close the cover plates on the front and back sides of the top of the packaging box. Then, the second motor 12 is started to rotate, driving the first positive and negative threaded rod to rotate, which in turn drives the movable columns 11 on both sides, the dual-axis motor 13 and the adjusting frame 14 to move closer to each other. The dual-axis motor 13 drives the two adjusting frames 14 in front and behind to rotate. The left adjusting frame 14 rotates counterclockwise and the right adjusting frame 14 rotates clockwise, which in turn moves the two sides of the packaging box to rotate towards each other, so that the angle between the two top coverings of the packaging box and the top plane of the packaging box is an acute angle. Then, the operator adjusts the pressure plate 24 to move down, and at the same time, adjusts the folding frame 7 to move up, so that the pressure plate 24 presses down the two top coverings of the packaging box, thereby completing the folding and closing of the coverings around the top of the packaging box. Then, the conveyor 31 transports the folded packaging box to the sealing box, and then the box is sealed.

[0032] To address the folding requirements of different packaging box models, this invention incorporates a series of flexible adjustment mechanisms. Firstly, the first electric cylinder 3 easily adjusts the vertical position of the drive box 4, causing the connected fixing block 5, the second electric cylinder 6, and the folding frame 7 to rise and fall synchronously, thus adapting to packaging boxes of varying heights. Secondly, the extension of the third electric cylinder 15 pushes the two side support plates 16 closer together, causing the limiting rod 17, tension spring 18, and clamping plate 19 to move closer as well. The clamping force generated by the tension spring 18, combined with the pressure detector 20 monitoring the pressure applied by the clamping plate 19 to both sides of the packaging box in real time, not only securely fixes packaging boxes of different specifications but also effectively prevents damage due to excessive pressure. Furthermore, the third motor 26 drives the second threaded rod 27 to rotate, causing the two movable frames 22 to move the fourth electric cylinder 23 and the pressure plate 24 closer or further apart, further enhancing the equipment's adaptability to packaging boxes of different sizes and fully meeting diverse production needs.
