Description

Technical Field

[0001] The invention relates to a paper folding device, in particular to a paper folding device used for card packaging. Background Art

[0002] The last step in smart card production is to pack the smart card and instruction page into an envelope. Before packaging, the instruction page needs to be folded to reduce the horizontal area, and finally the smart card and instruction page are placed in the envelope.

[0003] As automation technology matures, most operations are done directly by machines, such as the folding of instruction pages.

[0004] Existing folding shapes mainly include C-shape (i.e. folded in half, with one crease) and Z-shape, wherein the Z-shape includes two creases in opposite directions. Existing Z-shaped origami devices either fold on both sides at the same time, or fold one side first and then flip and fold the other side. Not only are the structures complex and space-consuming, but they can only be folded into specified shapes, and their versatility is poor. Summary of the invention

[0045] See also Figure 1-11 The working principle of the paper folding device for card packaging in this embodiment is as follows:

[0046] During operation, the paper to be folded is conveyed to the two sets of bending conveying components of the bending conveying mechanism close to the first set of paper folding modules 1, and the bending conveying components are driven to rotate in the corresponding direction by the bending conveying driving mechanism, and the two sets of bending conveying components squeeze and convey the paper to be folded forward, such as Figure 5 When the front end of the paper to be folded moves a certain distance in the bending and conveying assembly, the bending and conveying drive mechanism stops driving. At this time, a part of the paper to be folded is located between the two sets of bending and conveying assemblies, and the other part of the paper to be folded is at the rear. Figure 6 The turning frame 3 is driven to turn in the corresponding direction by the bending and turning driving mechanism, and the two sets of bending and conveying components are clamped with the paper to be folded and turned synchronously; as the turning angle increases, the position corresponding to the turning corner of the paper to be folded and the turning guide 4 begins to bend. At this time, the paper to be folded is not in a straight position, such as Figure 7 and 8 After the flip angle is greater than 90 degrees, the portion of the paper located behind the bent position begins to stick to the arc surface of the flip guide 4 until it flips to 180 degrees. At this time, the front end of the paper flips to the upstream of the paper conveying channel, and the bent position is located downstream of the paper conveying channel. Fig. 9 Next, the bending conveying assembly is driven to rotate in the opposite direction by the bending conveying driving mechanism, and the two sets of bending conveying assemblies continue to convey the paper forward. At this time, the bending position of the paper is located at the front end. When the bending position of the paper is close to the two flattening conveying rollers 19, the two flattening conveying rollers 19 press on the bending position of the paper to flatten the bending position of the paper and continue to convey the paper forward. Figure 10-11 For paper that is folded in half, just complete the above steps without folding it again.

[0047] For paper with at least two creases, it is necessary to continue folding; the next group of paper folding modules 1 takes over the paper, and according to the operation of the previous group of paper folding modules 1, the corresponding turning frame 3 is driven in the same direction by the bending and turning driving mechanism to turn it over, so that creases in the same direction can be obtained; the corresponding turning frame 3 is driven in the opposite direction by the bending and turning driving mechanism to turn it over, so that creases in the opposite direction can be obtained.

[0048] Follow the above steps until you have completed all the folding operations on the paper.

[0049] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
