Description

Technical Field

[0001] This utility model belongs to the field of cardboard folding devices, and particularly relates to a size-adaptive folding structure. Background Technology

[0002] After cutting the cardboard to a cross shape, it is folded to form an unclosed paper frame. In a typical folding device, the cardboard cross is placed on a base plate with the folding line on the base plate. By adjusting the structure, the folding line on the cardboard cross is placed at the edge of the base plate and pressed down to complete the folding. When adjusting the cardboard cross, one of the cardboard sections to be folded is usually clamped and moved for adjustment. The dimensions are generally fixed. If the width and length of the section to be folded change, such as if the width of the folded section changes, it may exceed the length of the pressing structure, resulting in part of the folding line of the paper not being pressed down by the pressing structure. If both the width and length of the folded section need to be changed, adjusting the structure may also cause the folding line of the paper not to be placed at the edge of the base plate. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a size-adaptive folding structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This embodiment provides a size-adaptive folding structure, combined with Figure 1-3 As shown, the machine includes a frame 10, a base plate 11 at the bottom of the frame 10, a pressure plate 12 that can be raised and lowered in the vertical direction above the base plate 11, a cardboard alignment and stretching structure 13 on the side of the base plate 11, the cardboard alignment and stretching structure 13 being movably mounted on the frame 10, and a folding and pressing structure 14 that can be raised and lowered in the vertical direction and can be extended laterally above the base plate 11.

[0023] In this embodiment, a cross-shaped cardboard is placed on a base plate 11. One section of the cardboard to be folded extends out of the base plate 11, and its left and right positions are adjusted by an alignment and stretching structure 13 to center the folded section. Then, the alignment and stretching structure 13 pulls the cardboard so that the fold line is at the edge of the base plate 10. The folding and pressing structure 14 adjusts its length according to the length of the fold line, ensuring its length matches the fold line. Finally, the folding and pressing structure 14 moves downwards to press down on the fold line, thus completing the folding of this section. The cardboard alignment and stretching structure 13 adapts to the width and length of different folded sections of the cross-shaped cardboard, and the folding and pressing structure 14 adapts to the length of different fold lines.

[0024] The cardboard alignment and stretching structure 13 includes a transverse frame 15, which is mounted on the frame 10 and can move horizontally to move away from or towards the base plate 11. The transverse frame 15 has alignment moving plates 16 at both ends, which are connected to the output shaft of a linear driver 17 mounted on the transverse frame 15. The alignment moving plates 16 can move closer to or further away from each other.

[0025] In this embodiment, during the process of moving the cross-shaped cardboard, the cross-shaped cardboard is placed on the base plate 10, and the part to be folded is located between the two alignment moving plates 16. The operation of the linear driver 17 causes the two alignment moving plates 16 to move an appropriate distance, clamping the part of the cardboard to be folded between the two alignment moving plates 16 and moving the cardboard so that the cardboard is located in the center position.

[0026] The cardboard alignment and stretching structure 13 also includes a pair of flexible clamps 18 disposed on the transverse frame 15. The flexible clamps 18 are connected to a drive device disposed on the transverse frame 15, and the flexible clamps 18 are located on one side of the base plate 11.

[0027] In this embodiment, there is a gap between the two flexible clamping plates 18. After the cross-shaped cardboard is placed on the base plate 10, the part of the cross-shaped cardboard to be folded is extended between the two flexible clamping plates 18 by the movement of the cardboard alignment and stretching structure 13. The part of the cross-shaped cardboard to be folded is clamped between the two alignment moving plates 16 and the cardboard is moved to the center position. After the cardboard is in the center position, the flexible clamping plates 18 clamp the part to be folded and the folding line is moved to the edge of the base plate 10 by the movement of the transverse frame 15 on the frame 10.

[0028] The transverse frame 15 has a cardboard backing surface 19 on the side away from the base plate 11, two alignment moving plates 16 are located at both ends of the cardboard backing surface 19, and there is a gap between the alignment moving plates 16 and the cardboard backing surface 19. The flexible clamping plate 18 is located at the center of the cardboard backing surface 19.

[0029] In this embodiment, after the cross-shaped cardboard is placed on the base plate 10, the transverse frame 15 moves forward so that the cardboard abuts against the cardboard abutment surface 19 of the transverse frame 15 and simultaneously moves the cardboard between the two flexible clamping plates 18. Then, the part of the cross-shaped cardboard to be folded is clamped between the two alignment moving plates 16 and the cardboard is moved so that the cardboard is in the center position. After that, the flexible clamping plates 18 clamp the part to be folded and the folding line is moved to the edge of the base plate 10 by the movement of the transverse frame 15 on the frame 10.

[0030] The surface of the alignment moving plate 16 is smooth.

[0031] The folding press structure 14 includes a lifting rod 20 slidably disposed on the frame 10. A first folding plate 21 is provided on the lifting rod 20. Second folding plates 22 are slidably disposed at both ends of the first folding plate 21. The second folding plates 22 are connected to an extension drive structure disposed on the lifting rod 20.

[0032] In this embodiment, the two second folding plates 22 are moved synchronously by the extension drive structure, the position of the second folding plates 22 is adjusted according to the length of the folding line, and then the folding line is pressed down by the downward movement of the lifting rod 20.

[0033] The extension drive structure includes a rotary motor 23 mounted on the lifting rod 20. A rotating rod 25 is mounted on the output shaft of the rotary motor 23. An extension rod 24 is slidably mounted on the lifting rod 20 on each side of the output shaft of the rotary motor 23. The extension rod 24 is connected to the corresponding second folding plate 22. The output shaft of the rotary motor 23 and the extension rod 24 are connected through the rotating rod 25. The two ends of the rotating rod 25 are rotatably connected to the output shaft of the rotary motor 23 and the extension rod 24, respectively.

[0034] In this embodiment, when adjusting the position of the second folding plate 22, the rotating motor 23 operates, and the rotation of the rotating rod 25 causes the two second folding plates 22 to move synchronously, moving away from or closer to each other, thereby adjusting the length of the entire folding and pressing structure 14 to match the length of the folding line.

[0035] The first folding plate 21 is provided with slide rods 26 at both ends, and the second folding plate 22 is slidably disposed on the corresponding slide rods 26. The first folding plate 21 and the second folding plate 22 are flush with the outer surface of the base plate 11.

[0036] The base plate 11 and the pressure plate 12 are respectively connected to a cardboard drive motor 27.

[0037] In this embodiment, after one of the folding parts completes the folding step, the base plate 11 and the pressure plate 12 rotate synchronously to make the cardboard rotate so as to fold the next part. The center part of the cardboard is the same size as or slightly larger than the base plate 11, which can provide some adjustment space during adjustment.
