[0002] A panel box, also known as a foldable panel box or a foldable turnover box, is a packaging container commonly used in logistics, warehousing and transportation. It is reusable, foldable and has a stable structure. Panel boxes are usually made of wood, plastic or metal to support goods and facilitate forklift transportation.

[0003] In the prior art, the plastic sheet material of the panel box is generally a plastic honeycomb panel, which has good strength. At the same time, because it is made of plastic material, it can be deformed to a certain extent, so as to be mechanically processed into the form of a panel box.

[0030] Furthermore, the loading component 200 adopts a chain transmission structure to load the plastic honeycomb panel, and the top of the loading component 200 is kept horizontally arranged so that the plastic honeycomb panel always remains parallel to the frame 100 during the loading process of the bending operation, so as to facilitate the bending of the plastic honeycomb panel. At the same time, the number of bending components 300 is set to four groups, and the four groups of bending components 300 are evenly distributed in a linear array on the upper surface of the frame 100, and the slide frames 311 corresponding to the four groups of bending components 300 are connected to each other through fixed connecting parts, and at the same time, the output end of the driving cylinder 310 is connected to the slide frame 311 on the side of the frame 100 closest to the driving cylinder 310, so that under the drive of the driving cylinder 310, the four groups of bending components 300 can perform synchronous movement in the horizontal direction on the upper surface of the frame 100, thereby synchronously realizing the bending of the plastic honeycomb panel.

[0031] In addition, there are two groups of lower connecting members 312 and lower cylinders 313, and the two groups of lower connecting members 312 and lower cylinders 313 are symmetrically arranged on the left and right sides of the slide frame 311 with the vertical central axis of the frame 100 as the symmetry axis, and the support frame 314 is kept parallel to the top surface of the slide frame 311. Further, the lower cylinder 313 is arranged vertically. At the same time, the support frame 316 is arranged between the roller 315 and the slide frame 311, and a heating pipe is arranged on the top of the support frame 314, and the top arc surface of the roller 315 is kept flush with the upper surface of the support frame 316. During the bending process, the plastic honeycomb panel at the top of the heating pipe is heated by the heating of the heating pipe, so that the heated part of the plastic honeycomb panel is softened to a certain extent. , so that it can be bent better, and after the bending process is completed, it is supported by the roller 315 to avoid interference with the loading and unloading of the plastic honeycomb panel, making its movement in the horizontal direction more stable. Specifically, there are two groups of upper connecting members 317 and upper cylinders 318, and the two groups of upper connecting members 317 and upper cylinders 318 are symmetrically arranged with the vertical central axis of the U-shaped frame 320 as the symmetry axis. In addition, the positioning frame 319 is arranged directly above the supporting frame 316. During the bending process, the upper cylinder 318 and the lower cylinder 313 are arranged, and the upper and lower limit fixation of the supporting frame 316 and the positioning frame 319 is coordinated to fix and limit one side of the plastic honeycomb panel, thereby facilitating the bending process of the plastic honeycomb panel by the bending plate 324.

[0032] In an embodiment of the present invention, a central controller is provided inside the control box 321, and the central controller is electrically connected to the feeding assembly 200, the driving cylinder 310, the lower cylinder 313, the upper cylinder 318, the pressurizing cylinder 322 and the heating pipe arranged above the support frame 314, so as to automatically control the bending processing of the plastic honeycomb panel to realize the automated processing of the bending of the plastic honeycomb panel of the enclosure box. At the same time, there are two groups of U-shaped frames 320, and the two groups of U-shaped frames 320 are symmetrically arranged on the left and right sides of the slide frame 311 with the central axis of the slide frame 311 as the symmetry axis. In addition, there are multiple groups of pressurizing cylinders 322, and the multiple groups of pressurizing cylinders 322 are evenly distributed in a linear array above the slide frame 311. Specifically, the vertical plate 323 and the bending plate 324 are both arranged vertically. At the same time, a triangular edge is provided at the bottom of the bending plate 324, so as to better realize the bending work of the plastic honeycomb panel.

[0033] Specifically, the bending plate 324 is arranged above the support plate 325 and the trapezoidal bracket 326. During the bending process, the pressurized cylinder 322 is started to drive the vertical plate 323 and the bending plate 324 to move downward, so as to extrude and bend the plastic honeycomb panel above the trapezoidal bracket 326. Furthermore, the trapezoidal bracket 326 includes a wide side and a narrow side, and the narrow side is arranged at the top to ensure the bending work of the plastic honeycomb panel while ensuring the stability of the trapezoidal bracket 326 itself.

[0035] In the present invention, when in use, the plastic honeycomb panel is driven to be transported linearly on the surfaces of the rollers 315 and the auxiliary rollers 330 through the operation of the loading assembly 200. After the plastic honeycomb panel moves to a fixed position above the frame 100, the heating pipe on the top of the support frame 314 is controlled to heat the plastic honeycomb panel on the top of the heating pipe, thereby softening the heated part of the plastic honeycomb panel to a certain extent. After heating for a predetermined time, the driving cylinder 310 is controlled to start to push the slide frame 311 The upper surface of the frame 100 is displaced in the horizontal direction, and the displacement distance is the spacing between the heating tube and the bending plate 324, so as to ensure that the preheated and softened part of the plastic honeycomb panel moves to the bottom of the bending plate 324. At this time, the pressurized cylinder 322 is controlled to start to drive the vertical plate 323 and the bending plate 324 to move downward, so that the softened part of the plastic honeycomb panel is squeezed and bent. Through the arrangement of the four groups of bending components 300, the plastic honeycomb panel is bent four times synchronously to complete the processing of the components of the enclosure panel.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
