Abstract
Description
Technical Field
[0001] The utility model relates to a paper transfer mechanism. Background Art
[0002] In the complex paper printing process, it is generally necessary to transfer the paper. When transferring the paper, since the paper is thin and easy to curl, and because the paper has a certain temperature after printing and is more likely to curl, it is necessary to install an anti-curling mechanism on the paper transfer mechanism. At present, when the existing anti-curling mechanism encounters papers of different thicknesses, it is necessary to adjust the distance from the transfer table, which is troublesome to operate and time-consuming. Content of the Utility Model
[0003] The utility model provides a paper transfer mechanism.
[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:[[]]
[0005] A paper transfer mechanism includes a transfer table. The transfer table is an inclined structure with one end high and the other end low. There are opposite protrusions on both sides of the downward-sloping end of the transfer table. There is a first fixed rod inside the protrusion, and there is a gap between the first fixed rod and the transfer table. Taking the midline as the reference in the middle of the first fixed rod, there are two opposite fixed rings on both sides of the midline. An anti-curling mechanism is connected inside the two fixed rings. The anti-curling mechanism includes a first rotating rod and a second rotating rod. The bottom ends of the first rotating rod and the second rotating rod are both sleeved on the fixed rod and fixed on the fixed ring with an axis. Several connecting pieces are sleeved on the rod bodies of the first rotating rod and the second rotating rod. An installation piece is provided at the lower end of each connecting piece. An elastic piece extending outwards is provided at the inner end of the installation piece. The end of the elastic piece is connected with a paper pressing wheel by an axis. The center of the paper pressing wheel is connected to the axis. The elastic piece is parallel to the first rotating rod or the second rotating rod, and the lowest point of the paper pressing wheel is lower than the lowest point of the installation piece.
[0006] Preferably, a second fixed rod is provided at the upward-sloping top end of the transfer table, and there is a gap between the second fixed rod and the transfer table.
[0007] Preferably, the front ends of the first rotating rod and the second rotating rod are fixedly connected by a connecting rod.
[0008] Preferably, the connecting piece is a circular ring body structure with one end open, sleeved on the first rotating rod and the second rotating rod, and the open side is tightened and fixed with a screw.
[0009] Compared with the prior art, in the paper transfer mechanism of the present utility model, a plurality of paper pressing wheels are arranged on the first rotating rod and the second rotating rod. During the printing and transfer process, the paper pressing wheels pass over the paper, playing a role in preventing the paper from curling. Moreover, elastic pieces are used to connect the paper pressing wheels, so that the distance between the paper pressing wheels and the transfer table is not completely fixed, and it can adapt to the passage of more papers with different thicknesses.

[0012] Figure 3 of the present utility model Figure 1 An enlarged view of part B. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The present utility model will be further described in detail below in conjunction with the embodiments of the drawings.
[0014] As Figures 1 to 3 shown, a paper transfer mechanism includes a transfer table 1, which is placed between two printing presses. The transfer table 1 is an inclined structure with one end high and the other end low. On both sides of the lower inclined end of the transfer table 1, there are opposite protrusions. Inside the protrusions, there is a first fixing rod 2. A gap is provided between the first fixing rod 2 and the transfer table 1 to allow the paper to pass through. At the upper inclined end of the transfer table 1, there is a second fixing rod. A gap is provided between the second fixing rod and the transfer table 1 to allow the paper to pass through, and at the same time, it plays a role in flattening the paper.
[0015] Taking the middle line of the first fixing rod 2 as the reference, on both sides of the middle line, there are two opposite fixing rings 21. Inside the two fixing rings 21, there is an anti - curling mechanism 3 connected. The anti - curling mechanism 3 includes a first rotating rod 31 and a second rotating rod 32. The front ends of the first rotating rod 31 and the second rotating rod 32 are fixedly connected by a connecting rod. The bottom ends of the first rotating rod 31 and the second rotating rod 32 are both sleeved on the fixing rod 2 and fixed on the fixing rings 21 by shafts, so that the first rotating rod 31 and the second rotating rod 32 can rotate around the fixing rod 2.
[0016] A plurality of connecting members 4 are sleeved on the rod bodies of the first rotating rod 31 and the second rotating rod 32. The connecting member 4 is a ring body structure with one end open. It is sleeved on the first rotating rod 31 and the second rotating rod 32, and the open side is tightened and fixed with screws. The position of the connecting member 4 on the first rotating rod 31 and the second rotating rod 32 can be changed according to specific situations and requirements; an installation member 5 is provided at the lower end of each connecting member 4. An elastic piece 6 extending outward is provided at the inner end of the installation member 5. The end of the elastic piece 6 is connected with a paper pressing wheel 7 by a shaft. The center of the paper pressing wheel 7 is connected to the shaft and can rotate around the shaft; the elastic piece 6 is parallel to the first rotating rod 31 or the second rotating rod 32, but the direction can be adjusted according to actual needs and can face the front end of the first rotating rod 31 or the second rotating rod 32 or the rear end of the first rotating rod 31 or the second rotating rod 32; the lowest point of the paper pressing wheel 7 is lower than the lowest point of the installation member 5.
[0017] When using the device, rotate the first rotating rod 31 and the second rotating rod 32 to the transfer table 1 so that the paper pressing wheel 7 is in contact with the transfer table 1. When the paper slides from the high end to the low end of the transfer table 1, since the just-printed paper has a certain temperature and is relatively easy to curl, during the transfer process, multiple paper pressing wheels 7 can play a role in preventing curling. At the same time, since the paper pressing wheel 7 is connected between the elastic piece 6 and the installation member 5, the distance between the paper pressing wheel 7 and the transfer table 1 is not completely fixed and can adapt to more papers of different thicknesses passing through.
[0018] In the paper transfer mechanism of the present utility model, by providing a plurality of paper pressing wheels 7 on the first rotating rod 31 and the second rotating rod 32, during the printing and transfer process, the paper pressing wheels 7 pass through the paper and play a role in preventing curling. And the elastic piece 6 is used to connect the paper pressing wheel 7, so that the distance between the paper pressing wheel 7 and the transfer table 1 is not completely fixed and can adapt to more papers of different thicknesses passing through.
[0019] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present utility model and do not limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
