Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as Figure 1-9 As shown, a paper clamping device includes a paper shelf 1 assembled on a speed printing machine or copier body 8, such as figure 1 As shown, and two cardboard assemblies arranged on the cardboard 1 at intervals in parallel, the described cardboard assembly includes a splint 2 and an additional board 3, and the splint 2 is arranged on the cardboard 1, as figure 2 As shown, the splint 2 can be an iron plate or a plastic plate, and the two splints 2 are connected through a linkage mechanism, and the two splints 2 can be synchronized to the two sides of the cardboard 1 through the action of the linkage mechanism. Translate sideways or in the middle to change the distance between the two splints 2 to adapt to the width of different papers, such as the width of A3 or A4 papers. The linkage mechanism is a conventional te...

The invention relates to a paper clamper, which comprises a paper laying plate (2) and two clamping plates on the paper laying plate, wherein said clamping plate comprises a clamping plate (2), an additional plate (3), while the clamping plate (2) is on the laying plate (1) and the additional plate (3) is at the outer side surface of clamping plate (2); there are at least two fixing columns (4) through at the back of additional plate (3) to be fixed with the clamping plate (2); the fixing column (4) is sheathed with flexible element (5); the inner side surface of additional plate (3) that exposing the clamping plate is fixed with friction block (6); and a driver is between the clamping plate (2) and the additional plate (3) to drive the additional plate far way the clamping plate (2); when the additional plate is near to the clamping plate most, the inner side surface of friction block (6) is inner the inner side surface of clamping plate (2); when the additional plate is far way the clamping plate most, the inner side of friction block (6) is at the outer side of inner side surface of clamping plate (2). The invention can be used to feed thick and thin papers, to avoid feeding several papers at one time.
Description
technical field [0001] The invention relates to a paper clamping device, which is widely used in various speed printing machines and printers. Background technique [0002] The paper clamping device in the paper feeding mechanism only plays the role of clamping the paper in the speed printer, and the paper enters the paper feeding system one by one through the paper feeding mechanism. In the original structure, due to the clamping on both sides The cardboard is an iron plate, which is suitable for the entry of slightly thicker paper. If the paper is too thin, it will be due to the effect of static electricity, and the friction between the paper and the iron clamping board is also prone to generate static electricity, resulting in double or multiple sheets. paper feed. In order to prevent double or multiple paper feeding, some speed printers adopt different paper feeding mechanisms for different paper thicknesses, which are divided into thin paper and thick paper positioning...
