Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and more specifically, to a paper side positioning device. Background Art

[0002] A die-cutting machine processes paper. Existing die-cutting machines mainly include a conveying device, a die-cutting device, a waste removing device, and an output device. During the paper processing, the paper needs to be bitten. The bite edge is the part of the paper that is bitten for printing or cutting. The role of the bite edge is very important. After printing is completed, the paper is cut by biting it to ensure that the paper is consistent with the packing box.

[0003] Existing paper needs to be transported before reaching the biting position for convenient biting at a suitable position later. Therefore, a support device is currently set up. However, the current support device is a relatively large flat plate, which cannot provide good support for different papers, such as smaller papers, and is prone to deviation. In addition, a clamping force needs to be applied to the paper, otherwise the paper is prone to deviation during biting, resulting in inaccurate biting positions. Summary of the Utility Model

Both ends of the lead screw 6 are installed on bearings 7. The bearings 7 are installed on the mounting plates 5 and the support plates 3. One end of the lead screw 6 is connected to a speed reducer 8. The speed reducer 8 is connected to a motor 9. The speed reducer 8 is installed on the mounting plate 5. A lead screw nut 10 is installed on the lead screw 6. One end of the lead screw nut 10 is installed with a support block 11. A side panel 12 is installed on the top of the support block 11. A side return plate 13 is installed on the support block 11. The side return plate 13 is perpendicular to the support plate 3.

[0030] When the paper or cardboard is conveyed, it first reaches the panel 1 and the crossover plate 2. The motor 9 operates to drive the speed reducer 8, and the speed reducer drives the lead screw 6 to rotate. The lead screw 6 drives the lead screw nut 10 to move horizontally. The lead screw nut 10 drives the support block 11 to move, the support block 11 drives the side panel 12 to move, and the side panel drives the side return plate 13 to move. In this way, the cardboard or paper can only move between the two side return plates 13, realizing the restriction of the paper.

[0031] In an embodiment of the present invention, the support block 11 includes a support side block 111 and a support top block 112. The side panel 12 is installed on the support top block 112. The support side block 111 is arranged on one side of the support top block 112, and the lead screw 6 passes through the bottom of the support side block 111. The support top block 112 functions to install the side panel 12.

[0032] In an embodiment of the present invention, a guide plate mounting plate 14 is installed at the upper end of the side panel 12, and the guide plate 15 is installed on the guide plate mounting plate 14.
