With this structure, the cardboard folding machine is equipped with a clamping assembly that can press or release the cardboard between the upper and lower roller assemblies. When processing is required, the clamping assembly presses the cardboard between the upper and lower roller assemblies for processing. When a paper jam occurs and the cardboard needs to be cleared, simply operating the clamping assembly to release the cardboard between the upper and lower roller assemblies allows for easy removal of the cardboard, avoiding disruption to machine operation and damage, and improving production efficiency.

[0026] As a specific embodiment rather than a limitation, in order to make the upper wheel group assembly 111 and the upper wheel group assembly 112 compressible or loosable, the upper wheel group assembly 11 comprises a side plate part 111, the compression assembly 3 is fixedly connected to the side plate part 111, and the compression assembly 3 comprises a quick compression piece 31 for pressing down or lifting the side plate part 111 and a bracket 32 for fixing the quick compression piece 31. The quick compression piece 31 comprises a compression handle 311, a guide column 312 and a fixed table 313, the compression handle 311 is swingable to abut against the fixed table 313, the fixed table 313 is fixed to the bracket 32, the guide column 312 penetrates the fixed table 313, the compression handle 311 is connected to the guide column 312, when the compression handle 311 swings, the guide column 312 moves along the axial direction, and the guide column 312 is connected to the side plate part 111. When the edge folding is needed, the paperboard is transmitted through the transmission gap between the upper wheel group assembly 111 and the lower wheel group assembly 112, when the compression handle 311 is swung and pressed down, the guide column 312 is lifted, the guide column 312 is connected to the side plate part 111, so that the upper wheel group assembly 11 moves away from the lower wheel group assembly 12 and the paperboard is loosened, when the compression handle 311 is vertical, the guide column 312 is pressed down, so that the upper wheel group assembly 11 moves towards the lower wheel group assembly 12 and the paperboard is compressed.

[0027] Further, in order to make the compression more easily, the quick compression piece 31 comprises a supporting spring 314 sleeved on the guide column 312, the guide column 312 is fixedly provided with an abutting block 3121, the supporting spring 314 is abutted at the lower end against the abutting block 3121 and at the upper end against the fixed table 313, and the supporting spring 314 is used for moving the upper wheel group assembly 11 towards the lower wheel group assembly 12. When the guide column 312 is pressed down, the elastic force of the supporting spring 314 acts on the abutting block 3121, so that the guide column 312 presses down the upper wheel group assembly 11, thereby moving the upper wheel group assembly 11 towards the lower wheel group assembly 12.

[0028] Further, in order to successfully fold the edge of the paperboard, the edge folding guide rail 2 comprises a lower guide plate 21, the lower guide plate 21 is provided with a pressing plate 22 for clamping the paperboard in cooperation with the lower guide plate 21 and a folding guide plate 123 for folding the paperboard, the folding guide plate 123 is connected to the pressing plate 22 in a head-tail mode, the folding guide plate 123 is curved at the front end to form a curved part 231. The paperboard passes through the lower guide plate 21 and the pressing plate 22, is fixed in the z-axis direction by the pressing plate 22, is moved along the lower guide plate 21 by the conveying assembly 1, and is transmitted to the folding guide plate 23. Since the folding guide plate 23 is curved at the front end to form the curved part 231, the paperboard is folded along the curved part after passing through the curved part 231, thereby forming the edge folding.

[0029] Furthermore, to enable simultaneous folding of both sides of the cardboard and to accommodate cardboard of different sizes, the folding guide rails 2 are movably positioned on both sides of the conveying assembly 1. When a larger cardboard fold is required, the folding guide rails 2 are positioned further away from the conveying assembly 1, and two sets of conveying assemblies 1 are installed between the two folding guide rails 2, forming a wider folding space, thereby enabling the folding of larger cardboard.

[0031] Furthermore, to prevent the cardboard from easily falling off after folding, the input end of the folding guide rail 2 is equipped with a glue spraying device 7 for applying glue to the cardboard. By setting up the glue spraying device 7 before folding, molten glue is applied to the cardboard, allowing the cardboard to adhere well during folding.

[0032] like Figures 5 to 7 The illustrated paperboard folding machine includes a folding mechanism for folding the edges of cardboard.

[0033] As a specific implementation and not a limitation, the invention includes two cardboard folding machines, a conveying mechanism 4, a rotating mechanism 5, and a box-forming mechanism 6.

The rotating mechanism 5 is used to rotate the folded cardboard and convey the rotated cardboard to the other cardboard folding mechanism for further folding. Finally, the cardboard is conveyed to the box-forming mechanism 6 for box-forming to form a complete box.

[0034] Furthermore, such as Figure 8 The rotating mechanism shown includes a rotating assembly 51 and a clamping assembly 52. ​​The rotating assembly 51 rotates the cardboard after the clamping assembly 52 clamps it. The clamping assembly 52 includes a pressure roller 521, a clamping plate 522, and a pressure cylinder. The pressure cylinder causes the clamping plate 522 to cooperate with the pressure roller 521 to clamp the cardboard. The folded cardboard is transferred to the clamping plate 522 in the rotating mechanism 5. The pressure cylinder operates, pushing the clamping plate 522 upward, causing it to press against the pressure roller 521 and clamp the cardboard. Simultaneously, the rotating assembly 51 rotates, causing the cardboard to rotate by 90°.

[0035] Furthermore, such asFigure 7 The shown box forming mechanism 6 comprises a mold 61, a mold motor 62 and a box collecting assembly 63, the mold 61 is fixed on the mold motor 62, the box collecting assembly 63 is a cage-shaped collecting device, the flanged paperboard is transmitted to the open end of the box collecting assembly 63 in the box forming mechanism 6, the mold motor 62 starts to work, pushes the mold 61 out to the middle of the paperboard, so that the paperboard around is adhered to the box collecting assembly 63 and is folded, and then a complete box body is formed.

[0036] The specific embodiment of the utility model is:
