Detailed Implementation

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 6As shown in the figure, a double-sided folding and creasing machine of this utility model includes a folding worktable, a fixed support 5, a top beam 1, and a creasing assembly. The two ends of the top beam 1 are respectively connected to the upper part of one of the fixed supports 5. A folding worktable is arranged opposite to each other on both sides of the top beam 1. One side of the lower part of the fixed support 5 is connected to one of the folding worktables, and the other side of the lower part of the fixed support 5 is connected to another folding worktable. A creasing gap is provided between the two folding worktables. The creasing assembly is arranged above the creasing gap and is connected to the top beam 1. The folding workbench includes a main board 7, a folding plate 9, and a hinge assembly. One side of the main board 7 is connected to the lower part of the fixed bracket 5, and the other side of the main board 7 is rotatably connected to the folding plate 9 through the hinge assembly.

[0026] The working principle of this utility model is as follows: When it is necessary to creasing paper during the actual use of the creasing machine, the paper can be placed on two folding worktables, and the part to be creasing is aligned with the creasing gap. Then, the creasing component is pressed so that the creasing component and the creasing gap cooperate to creasing the paper. Then, the paper is moved to creasing again. When it is necessary to transport the whole device, the folding plate 9 can be flipped so that the folding plate 9 is flipped under the main board 7 through the hinge component to complete the folding. Then, the whole device can be transported.

[0027] Furthermore, the hinge assembly includes a rotating seat 17 and a rotating shaft 18. The rotating seat 17 is provided on the side of the main board 7 away from the indentation assembly, and the rotating shaft 18 is provided on the side of the folding plate 9 close to the main board 7. The rotating shaft 18 is rotatably connected to the rotating seat 17.

[0028] As can be seen from the above description, the folding plate 9 is better connected to the main board 7 by the rotating seat 17 and the rotating shaft 18, which makes it easier to fold and reduce the packaging volume during storage and transportation.

[0029] Furthermore, the indentation assembly includes a pressing component, a tool holder 6, an indentation tool 4, and a reset component. The pressing component is connected to the top beam 1. The tool holder 6 is disposed on the inner side of the top beam 1. The pressing component is connected to the tool holder 6. Both sides of the tool holder 6 are slidably connected to a fixed bracket 5. The indentation tool 4 is connected to the tool holder 6 and is disposed above the indentation gap. The tool holder 6 is connected to the top beam 1 through the reset component.

[0030] As can be seen from the above description, when it is necessary to creasing paper, the paper can be placed on the creasing gap, and then the pressing component is pressed down, so that the pressing component drives the knife holder 6 to slide down on the fixed bracket 5. At the same time, the knife holder 6 drives the creasing knife 4 to creasing the paper. Then, the hand is released, so that the knife holder 6 is reset under the action of the reset component.

[0031] Furthermore, the fixed bracket 5 is provided with a sliding groove 21, and the tool holder 6 is slidably connected to the sliding groove 21. The width of the upper part of the sliding groove 21 is greater than the width of the lower part of the sliding groove 21.

[0032] As can be seen from the above description, the upper-wide and lower-narrow groove 21 is conducive to better guiding the knife holder 6, so that the knife holder 6 and the creasing knife 4 can achieve higher precision when creasing paper.

[0033] Furthermore, the pressing assembly includes a rotating handle 2 and an extrusion member 20. One side of the rotating handle 2 is rotatably connected to the top beam 1 via a rotating shaft. The extrusion member 20 is provided on the rotating handle 2. The top beam 1 is provided with a through hole. The extrusion member 20 passes through the through hole and is connected to the knife holder 6.

[0034] As can be seen from the above description, when it is necessary to push the tool holder 6 down, the other side of the rotating handle 2 can be pressed to make the rotating handle 2 drive the pressing member 20 to abut against the top of the tool holder 6 and drive the tool holder 6 to move downward.

[0035] Furthermore, the reset assembly includes a mounting rod 3 and a reset spring 22. The upper part of the mounting rod 3 is detachably connected to the top beam 1, and the tool holder 6 is slidably connected to the mounting rod 3. The reset spring 22 is sleeved on the outside of the mounting rod 3, and a limit block 23 is provided at the lower part of the mounting rod 3. One end of the reset spring 22 abuts against the outer surface of the tool holder 6, and the other end of the reset spring 22 abuts against the outer surface of the limit block 23.

[0036] As can be seen from the above description, when the tool holder 6 moves downward, it slides on the mounting rod 3, and at the same time, the tool holder 6 compresses the return spring 22. After the downward pressure is released, the tool holder 6 returns to its original position under the action of the return spring 22.

[0037] Furthermore, reinforcing plates 14 are provided on both sides of the indentation gap.

[0038] As can be seen from the above description, it is beneficial to improve the strength of the indentation gap and extend the service life.

[0039] Furthermore, it also includes a positioning component. Both sides of the motherboard 7 and the folding plate 9 are provided with slide rails 19, and the positioning component is slidably connected to the slide rails 19. The positioning component includes a positioning rod 8 and a locking element 13. The positioning rod 8 is slidably connected to the main board 7 and the folding plate 9 via the slide rail 19. A locking element 13 is provided on both sides of the positioning rod 8. The positioning rod 8 is detachably connected to the slide rail 19 via the locking element 13.

[0040] As can be seen from the above description, the positioning rod 8 can slide and adjust its position on the main board 7 and the folding plate 9 via the slide rail 19, and after the adjustment is completed, the positioning rod 8 is locked by the locking member 13, so that the paper that needs to be creasing can be positioned against the positioning rod 8. When it is necessary to creasing the spine of the paper, the paper can first be placed against one positioning rod 8 and creasing is performed by the creasing component. Then the paper can be placed against another positioning rod 8 and creasing is performed by the creasing component, thereby completing the double-sided continuous creasing.

[0041] Furthermore, the positioning rod 8 is provided with an anti-penetration protrusion 15 on the side near the main board 7, and the upper surfaces of the main board 7 and the folding plate 9 are provided with anti-penetration grooves 12 that are adapted to the anti-penetration protrusion 15. The anti-penetration protrusion 15 of the positioning rod 8 and the anti-penetration groove 12 are slidably connected.

[0042] As can be seen from the above description, the positioning rod 8 can slide in the anti-penetration groove 12 through the anti-penetration protrusion 15, which prevents the metal sheet from entering the gap between the positioning rod 8 and the main board 7 when the metal sheet is indented, thus making the positioning more accurate.

[0043] Furthermore, the upper surfaces of the main board 7 and the folding plate 9 are also provided with a ruler groove 10, and a scale sticker is provided in the ruler groove 10.

[0044] As can be seen from the above description, this helps to fit the scale sticker into the groove 10, preventing the positioning rod 8 from peeling off the scale sticker when it moves.

[0045] Furthermore, both the main board 7 and the folding plate 9 are provided with support feet 16 at their lower parts, and both the main board 7 and the folding plate 9 are provided with clearance holes 11 that are adapted to the support feet 16.

[0046] As can be seen from the above description, it is beneficial to support the motherboard 7 and the folding plate 9 through the support foot 16, while the support foot 16 in the folded state is stored and avoided through the clearance hole 11. Example 1
