Description

Technical Field

[0001] The utility model relates to the field of paper processing equipment design, in particular to a page tearing machine without paper holes. Background Art

[0002] After the production and processing of paper, its original size is often large. A page tearing machine is a machine used to paginate paper. After the original size of paper is processed by the page tearing machine, it can be divided into several unit papers of specific sizes. The page tearing machine can be used for processing various types of leaflets, tickets, forms, bills, payment notices, etc.

[0003] When the existing page tearing machine is tearing pages, the paper to be torn needs to be preset with holes. During processing, the page tearing machine is positioned by the holes on the paper to tear the pages. However, the above-mentioned page tearing machine is positioned by the holes, and the positioning speed is slow, which affects the processing efficiency. Moreover, on the processed paper, it is often necessary to cut off a lot of paper edges to effectively remove the holes on the paper, which wastes a lot of materials, increases processing costs, and has weak market competitiveness. Utility Model Content

The traction paper feeding roller group can pull the paper with a preset cross-rolling line to the front tearing roller group. The paper can move to the conveying roller group after passing through the front tearing roller group and the rear tearing roller group. The conveying roller group can convey the paper to the belt conveying device.

[0007] The front tearing roller group includes a front upper roller and a front lower roller, and the rear tearing roller group includes a rear upper roller and a rear lower roller. The front lower roller is provided with a first convex position, and the rear lower roller is provided with a second convex position. The first convex position and the second convex position can simultaneously abut against the paper passing through the front tearing roller group and the rear tearing roller group.

[0008] The beneficial effect of the utility model is that in the utility model, the paper can be input into the utility model by pulling the paper feeding roller group, and with the conveyance of each roller group, when the paper passes through the specific required length of the rear tearing roller group, that is, the length and the length of the horizontal rolling line on the paper are matched, the first convex position and the second convex position can be simultaneously pressed against the paper passing through the front tearing roller group and the rear tearing roller group, and as the paper continues to be conveyed, the paper of a specific length can be torn off to obtain the paper of a specific length. Therefore, the utility model does not need to set holes on the paper for positioning the tearing of the paper, which reduces the waste of materials, and it is easy to adjust the rotation speed of the front tearing roller group and the rear tearing roller group to match the required paper length, which has strong flexibility and market competitiveness.

[0009] In some embodiments, the utility model further comprises a tension balancing roller set, which is mounted on a frame and can be against the paper. The setting of the tension balancing roller set can provide a certain tension for the transportation of the paper, effectively reducing the probability of folding of the paper during transportation.

[0010] In some embodiments, the tension balancing roller group includes an upper pressing roller and a lower pressing roller, both of which are installed on a frame, and both of which are against the paper.

[0011] In some embodiments, the utility model further comprises a paper shaking table and a stand, wherein the paper shaking table is mounted on the stand, the paper shaking table is provided with a paper holding cavity, and the belt conveying device can convey paper to the paper holding cavity. The setting of the paper shaking table can facilitate the collection and arrangement of the torn paper towels.

[0012] In some embodiments, the traction paper feeding roller set includes a first guide roller and a second guide roller, both of which are mounted on a frame, and the first guide roller and the second guide roller can be set at different heights, and the paper can bypass the guide roller and the power roller. Then, the first guide roller can adapt to the subsequent height setting of other roller sets, and the second guide roller can adapt to the height of an external paper conveying device, so that the traction paper feeding roller set can effectively adapt to the use of the utility model and the external paper conveying device.

[0013] In some embodiments, the conveying roller set includes a first conveying roller and a second conveying roller, both of which are mounted on a frame, and the paper can pass between the first conveying roller and the second conveying roller.

[0014] In some embodiments, the frame includes a base and a mounting plate, the mounting plate is connected to the base, and the traction paper feed roller group, front tearing roller group, rear tearing roller group, conveying roller group and belt conveying device are all installed on the mounting plate.

[0015] In some embodiments, the utility model further comprises a first side plate and a second side plate, wherein the first side plate is connected to one side of the base, and the second side plate is connected to the other side of the base. The first side plate and the second side plate can be arranged to hide and protect the installation part of most roller groups to reduce pollution of the installation part by the outside world.
