Description

Technical Field

[0001] The invention relates to the technical field of packaging box transfer, and in particular to a multi-layer transfer device for processing plastic packaging boxes. Background Art

[0002] Plastic packaging boxes are a type of container widely used for packaging, transporting and storing various items. They are lightweight, durable and multifunctional. Plastic packaging boxes are usually made of high-strength plastic materials and can withstand greater impact and pressure. There are many types of plastic packaging boxes. For example, in the processing of diamond-shaped plastic packaging boxes, a transfer device is generally used to store and transfer the diamond-shaped plastic packaging boxes in layers. Since the diamond-shaped plastic packaging boxes are lighter, a clamping device is required to push the packaging boxes so that adjacent packaging boxes are close to each other, reducing the distance between adjacent packaging boxes, and facilitating the clamping of multiple packaging boxes on the layering board. The larger the mass volume of the packaging box, the larger the gap between adjacent placement layers, which changes the clamping position of the clamping device and the outside of the packaging box. The larger the volume of the packaging box, the more curved its external curvature, resulting in less contact between the clamping device and the outside of the packaging box, which makes it easy for the clamping device to slide when clamping the packaging box, and it is necessary to frequently adjust the angle of the packaging box, increasing the time required for the packaging box transfer. Summary of the invention

[0003] The object of the present invention is to provide a multi-layer transfer device for processing plastic packaging boxes. By setting a limiting component, a stable interference between the limiting partition plate and the diamond-shaped packaging box can be achieved, so that there is a larger contact surface between the limiting partition plate and the diamond-shaped packaging box, which is conducive to the stable placement of the diamond-shaped packaging box in the shipping box vehicle, ensuring that the diamond-shaped packaging box has good stability, and can reduce the number of times the angle of the diamond-shaped packaging box is adjusted, reducing the time required for transferring the diamond-shaped packaging box, so as to solve the above-mentioned deficiencies in the technology.

[0022] The compensation component 4 includes a soft pad plate 41 installed on the top of the diamond-shaped swing plate 27 and a limit groove 42 opened on the top of the diamond-shaped swing plate 27 for the soft pad plate 41 to slide. The bottom end of the soft pad plate 41 and the bottom wall inside the limit groove 42 are both installed with support blocks 43, a spring seat 45 is installed between the two support blocks 43, and a spring 44 is installed between the two spring seats 45.

[0023] Through the above technical solution: When the diamond-shaped packaging box 11 is impacted, the threaded column plate 57 is first taken out of the threaded groove 51 to contact the restriction of the impact plate 53, and the impact plate 53 is pulled to drive the latch column 54 to slide along the guide hole 56, and then the latch column 54 slides out along one of the latch grooves 55. At this time, the first swing arm 25 is rotated to drive the adjustment ring 52 to rotate along the slider 21. However, the rotation of the first swing arm 25 drives the diamond-shaped swing plate 27 to rotate in the limiting partition plate 28. As the diamond-shaped swing plate 27 rotates, its top is moved toward the outside of the diamond-shaped packaging box 11, so that the top of the diamond-shaped swing plate 27 is in contact with the outside of the diamond-shaped packaging box 11, and then the soft pad plate 41 is pre-contacted with the outside of the diamond-shaped packaging box 11, and the soft pad plate 41 and the diamond packaging box 11 are squeezed by each other through the contact between them, and the soft pad plate 41 is pushed to move into the limiting groove 42, and one of the support blocks 43 is close to the other support block 43, and the two spring seats 45 are contracted, so that The spring 44 is squeezed and contracted between the two spring seats 45, and then the spring 44 itself is elastic, giving one side thrust to one of the support blocks 43, so that one of the support blocks 43 pushes the cushion plate 41 to move outside the diamond-shaped packaging box 11, so that the cushion plate 41 and the diamond-shaped packaging box 11 are adaptive, and then the top of the cushion plate 41 is squeezed and deformed, increasing the contact surface between the diamond-shaped swing plate 27 and the outside of the diamond-shaped packaging box 11, so that the diamond-shaped swing plate 27 and the diamond-shaped packaging box 11 can be stably fitted, and the contact plate 53 is pushed in the reverse direction to move the latch column 54 along the guide hole 56 into the slider 21, and then the latch column 54 is inserted into another latch groove 55, and the adjustment ring 52 and the first swing arm 25 are pre-restricted in the slider 21, and then the threaded column plate 57 is rotated to screw it with the threaded groove 51, and the contact plate 53 is squeezed and fixed between the threaded column plate 57 and the slider 21.
