Description

Technical Field

[0001] The utility model relates to the technical field of paper folding machines, in particular to a thick paper folding machine. Background Art

[0002] In the current field of paper processing and printing technology, especially in application scenarios involving multi-dimensional folding processes, a significant limitation is the singleness of the existing technology for paper folding functions. Although there are many origami equipment on the market that play a role in their respective fields, most of them focus on folding operations in a single direction, either longitudinally or transversely. This means that in the actual production process, if the composite folding effect of paper is to be achieved (i.e., both longitudinally and transversely), it has to be completed by multiple operations or replacement of different equipment. This process is not only cumbersome and complicated, but also inefficient, increasing the frequency of manual intervention, which can easily lead to paper misalignment and inaccurate folding, affecting the quality of the finished product. In addition, frequent manual operations and equipment switching also limit the automation process of the production process, which is not conducive to improving overall production efficiency and reducing costs. In view of this, the market demand for equipment that can integrate and automatically complete the longitudinal and transverse continuous folding of paper is growing, aiming to solve the shortcomings of current technology in flexibility, precision, efficiency and automation, and promote the paper processing industry to develop in a more efficient and high-quality direction.

[0027] Embodiment 1:

[0028] Figure 1-Figure 6The utility model shows a thick paper folding machine provided by the utility model, which is used for folding paper longitudinally and transversely, and includes a barrier folder 1, a first transverse folding mechanism 2 and a second transverse folding mechanism 3. The barrier folder 1 is used for folding paper longitudinally, the first transverse folding mechanism 2 is arranged at the output end of the barrier folder 1, and can perform the first transverse folding on the paper, and the second transverse folding mechanism 3 is arranged at the output end of the first transverse folding mechanism 2, and can perform the second transverse folding on the paper.

[0029] In this embodiment, an existing fence-type folding machine 1 is used, which includes a paper feeding table, a fence page, and a paper pickup roller. When started, the paper on the paper feeding table is prevented from being drawn into the interior, and the paper is repeatedly folded in the longitudinal direction through the cooperation of the fence page and the paper pickup roller.

[0030] The input port of the first transverse folding mechanism 2 is connected to the output port of the fence-type folder 1 through a first longitudinally arranged paper feeding mechanism 4. The paper that has been repeatedly folded longitudinally is fed into the first transverse folding mechanism 2 by the first paper feeding mechanism 4. A first folding knife 21 with an up and down stroke and arranged transversely is provided above the output end of the first paper feeding mechanism 4. A first paper pickup roller group 22 cooperating with the first folding knife 21 is provided below the output end of the first paper feeding mechanism 4. The first folding knife 21 moves downward to squeeze the paper in the transverse direction so that it is folded transversely. In cooperation with the first paper pickup roller group 22, the paper after the first transverse folding can be output downward. A second transversely arranged paper feeding mechanism 5 is provided below the first paper pickup roller group 22. The second paper feeding mechanism 5 is used to receive the paper and transport it to the second transverse folding mechanism 3.

[0031] The second transverse folding mechanism 3 includes a third paper feeding mechanism 6 and a fourth paper feeding mechanism 7 which are arranged transversely. The input end of the third paper feeding mechanism 6 is connected to the output end of the second paper feeding mechanism 5. The output end of the third paper feeding mechanism 6 is provided with a folding frame 33, a second folding knife 31 which is arranged transversely, and a second paper pickup roller group 32. The second folding knife 31 has an up and down stroke and is arranged above the third paper feeding mechanism 6. The second paper pickup roller group 32 is arranged below the third paper feeding mechanism 6. The folding frame 33 is separated from the third paper feeding mechanism 6. When the paper is output from the third paper feeding mechanism 6, part of it is stuck in the folding frame 33. The folding frame 33 The gap between the second folding knife 31 and the third paper feeding mechanism 6 is sufficient for the second folding knife 31 to pass through. Similar to the first folding knife 21, the second folding knife 31 can move downward to squeeze the paper in the horizontal direction, so that it can be folded horizontally for the second time. In cooperation with the second paper pickup roller group 32, the paper after the first horizontal folding can be output downward to the fourth paper feeding mechanism 7. A receiving paper board is provided at the output end of the fourth paper feeding mechanism 7. A stopper 71 is provided on the receiving paper board corresponding to the outlet of the fourth paper feeding mechanism 7. The stopper 71 has a large weight. After being output from the fourth paper feeding mechanism 7, multiple papers are blocked by the stopper 71 and stacked at the stopper 71 and the output outlet of the fourth paper feeding mechanism 7.

[0032] Since the fence-type folding machine 1, the first transverse folding mechanism 2 and the second transverse folding mechanism 3 have different heights, and when folding paper, the height of the output port and the height of the input port have certain specifications, the second paper feeding mechanism 5 is set at an angle, and its inclination angle is set according to the actual situation, and the height requirement of paper input and output.

[0033] The middle part of the end of the first paper feeding mechanism 4 is connected vertically to form a first through slot 41, through which the folding knife can pass. Both sides of the first through slot 41 are inclined downward to form guide plates 42, which facilitate the folding of paper downwards and prevent paper jams.

[0034] A second through slot is formed at the upper end of the folding frame 33, and an adjustment plate 331 is movably connected to the second through slot. A baffle 332 is connected to the lower end of the adjustment plate 331, and the baffle 332 passes through the through slot and extends into the fixed frame to block the paper. An adjustment through slot 333 is formed on the adjustment plate 331, and a screw hole 334 is formed at the upper end of the fixed frame corresponding to the position of the adjustment through slot 333. When the bolt is tightened and fixed in the screw hole 334, the nut part thereof is pressed against the adjustment plate 331, and the position of the baffle 332 is changed by moving the adjustment plate 331, thereby changing the second horizontal folding position of the paper.

[0035] The first paper receiving mechanism, the first paper receiving mechanism, the first paper receiving mechanism, the first paper receiving mechanism, and the first paper receiving mechanism mentioned in this embodiment include at least one transmission mechanism and a limiting mechanism, which can clamp the paper and transport it.

[0036] Working principle:

[0037] First, the paper is stacked at the input port of the barrier folder 1. After the barrier folder 1 is started, the paper is repeatedly folded longitudinally, and then fed into the first transverse folding mechanism 2 through the first paper feeding mechanism 4. The first folding knife 21 in the first transverse folding mechanism 2 squeezes the paper to make it transversely folded for the first time. After folding, it is transported to the second folding knife 31 through the second paper feeding mechanism 5 and the third paper feeding mechanism 6. The second folding knife 31 squeezes the paper to make it transversely folded for the second time, and then it is sent to the receiving paper board through the fourth paper feeding mechanism 7.

[0038] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
