Description

Technical Field

[0001] The present application relates to the field of copiers, and in particular to an anti-paper jam mechanism for copiers. Background Art

[0002] A copier is an electrostatic copying device that analyzes the image of the original to produce a latent image that is a combination of electric charge and light energy. This latent image is then attached to a charged photosensitive drum, and then through the adsorption of toner, a replica that is identical or similar to the original is formed.

[0003] Patent document with announcement number CN216434678U discloses a copier that facilitates heat dissipation. In the above application document, an exhaust fan in the exhaust chamber promotes air flow inside the copier, generating a thermal convection effect, so that excess heat is discharged outside the copier, thereby achieving the purpose of cooling. By specially constructing the five sides of the exhaust chamber except the bottom surface, a certain shielding effect is achieved on dust entering the copier, thereby ensuring a dust-free environment inside the copier to a certain extent.

[0004] Although this application can cool down the interior of the copier, when in use, paper is mostly transported through a paper feed roller. When the paper feed roller is transporting paper, it has no limiting device, which can easily cause paper deviation and thus cause paper jam. Utility Model Content

[0026] When the above-mentioned equipment is in use, the first hydraulic cylinder 64 drives the pushing frame 65 to move upward, and the upward movement of the pushing frame 65 drives the sliding frame 66 to flip inward and upward on the fixed plate 67, and the inward and upward flipping of the sliding frame 66 drives the first connecting plate 68 to move inward, and the inward movement of the first connecting plate 68 drives the first pull plate 69 on the outside to move inward on the support frame 613, so that the moving frame 611 on the second pull plate 610 at the bottom of the first pull plate 69 moves upward on the limit frame 612, so that the moving frame 611 can move upward stably, and the upward movement of the moving frame 611 drives the connecting frame 615 to move upward, and the upward movement of the connecting frame 615 drives the pressure plate 3 to move upward from the feed port 2, and the opposite movement can achieve downward movement.
