Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to an auxiliary limiting device for paper cutters. Background Art

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer-controlled, color-display, full-image operation-guided visual processing, and computer-aided cutting systems with external programming and editing of production data, making production preparation time shorter, cutting more accurate, labor-intensive, and safer to operate.

[0003] However, the existing paper cutter needs to be manually limited when working. If the staff makes a mistake, the cut paper will not meet the requirements. At the same time, the cutter is not easy to replace quickly, which reduces the work efficiency.

[0004] The existing patent (publication number: CN217345722U) discloses an auxiliary limit device for a paper cutter. In the process of realizing the utility model, the inventor found that the prior art has the following problems: 1. The device uses a support platform and an auxiliary push plate in combination to prevent the top layer of paper from being deviated when being cut, but the paper pressing mechanism cannot completely limit and fix the paper, and the paper will still deviate when being cut, resulting in poor quality; 2. The device uses a manual method to adjust the distance between the limit plate and the cutter, but there will still be a large error during manual adjustment, resulting in damage to the paper during the cutting process. Utility Model Content

[0021] In this embodiment, Figure 1 and Figure 2 As shown, two identical cylinders 4 and limiting plates 5 are provided, and are symmetrically distributed about the central axis of the shell 3; since two identical cylinders 4 and limiting plates 5 are provided, and are symmetrically distributed about the central axis of the shell 3, when the paper is against the push plate 7, the cylinders 4 on both sides are started, and the limiting plates 5 are driven by the cylinders 4 to move, so that the limiting plates 5 are completely against the two sides of the paper, and the paper is fixed in one position, so that there will be no deviation when the push plate 7 pushes the paper.

[0022] In this embodiment, Figure 3 As shown, the cylinder 2 6 penetrates the shell 3 and extends to the inner side of the push plate 7, and the push plate 7 is located between the limit plates 5; before use, put the paper into the shell 3 so that the paper is completely against the push plate 7, and when the paper cutter is working, start the cylinder 2 6, and drive the push plate 7 to move through the cylinder 2 6, and drive the paper forward through the push plate 7, while ensuring that the paper is completely in the same plane to prevent the different positions of the paper from causing the quality of the cut paper to be reduced.

[0023] In this embodiment, Figure 3As shown, cylinder three 8 passes through the shell 3 and extends to the upper end of the pressure plate 9, and the center lines of cylinder three 8 and the pressure plate 9 are located on the same vertical line; before the paper is cut, it is necessary to start cylinder three 8, and the pressure plate 9 is driven by cylinder three 8 to move, so that the pressure plate 9 is against the uppermost end of the paper, to prevent the top layer of paper from shifting when the cutter 12 is cutting, causing the subsequent paper to shift in the opposite direction, thereby reducing the error rate of cutting.

[0024] In this embodiment, Figure 1 and Figure 4 As shown, electric telescopic rods 11 are arranged on both sides of the lower end of the connecting plate 10, and the electric telescopic rods 11 are symmetrically distributed about the center line of the connecting plate 10; because the electric telescopic rods 11 are arranged on both sides of the lower end of the connecting plate 10, and the electric telescopic rods 11 are symmetrically distributed about the center line of the connecting plate 10, the paper is completely fixed by the limit plate 5, the push plate 7 and the pressure plate 9, and the cutter 12 is driven by the electric telescopic rods 11 on both sides to cut, so that the paper size required can be quickly obtained.

[0025] In this embodiment, Figure 4 As shown, the same number of connecting posts 13 and connecting holes 14 are provided, and the connecting posts 13 and connecting holes 14 are plug-connected; the connecting posts 13 are aligned with the connecting holes 14 so that the connecting posts 13 completely enter the interior of the connecting holes 14, and the installation between the cutter 12 and the electric telescopic rod 11 can be completed. If the cutter 12 fails, it can also be quickly disassembled, thereby improving work efficiency.

[0026] The use method and advantages of the utility model: When the auxiliary limit device for the paper cutter is used, the working process is as follows:

[0027] like Figures 1 to 4As shown, first, before use, put the paper into the shell 3 so that the paper is completely against the push plate 7. Since two identical cylinders 1 4 and limit plates 5 are provided and are symmetrically distributed about the central axis of the shell 3, when the paper is against the push plate 7, the cylinders 1 4 on both sides are started, and the limit plates 5 are driven to move by the cylinders 1 4, so that the limit plates 5 are completely against both sides of the paper, and the paper is fixed in a position, so that there will be no deviation when the push plate 7 pushes the paper. When the paper cutter is working, the cylinder 2 6 is started, and the push plate 7 is driven to move by the cylinder 2 6, and the paper is driven forward by the push plate 7, and at the same time, it is ensured that the paper is completely in the same plane to prevent the different positions of the paper from causing the quality of the cut paper to become low. Before the paper is cut, it is necessary to start the cylinder 3 8, and the cylinder 3 8 is driven by the cylinder 3 8 The pressing plate 9 is driven to move so that the pressing plate 9 is against the uppermost end of the paper, preventing the topmost paper from being offset when the cutter 12 is cutting, causing the subsequent paper to be offset in the opposite direction, thereby reducing the error rate of cutting. Since the electric telescopic rods 11 are arranged on both sides of the lower end of the connecting plate 10, and the electric telescopic rods 11 are symmetrically distributed about the center line of the connecting plate 10, the limit plate 5, the push plate 7 and the pressing plate 9 completely fix the paper, and the cutter 12 is driven to cut by the electric telescopic rods 11 on both sides, so that the paper size required can be quickly obtained, and the connecting column 13 is aligned with the connecting hole 14 so that the connecting column 13 completely enters the interior of the connecting hole 14, the installation between the cutter 12 and the electric telescopic rod 11 can be completed. If the cutter 12 fails, it can also be quickly disassembled, thereby improving work efficiency.
