Air suction inverted twisting type single-sheet feeding device

Abstract

The invention discloses an air suction inverted twisting type single-sheet feeding device. The air suction inverted twisting type single-sheet feeding device comprises a sheet feeding table, and the sheet feeding table comprises a rack, a lifting mechanism and a sheet feeding plate; the rack of the sheet feeding table comprises a vertical plate in the middle and side supporting plates arranged at the left and right ends; the lifting mechanism is mounted at the back of the vertical plate; the sheet feeding plate is mounted on the lifting mechanism; a suction nozzle air guide tube and a cam driving shaft are horizontally mounted between the two side supporting plates; at least two suction nozzles which communicate with the suction nozzle air guide tube are sequentially mounted on the suction nozzle air guide tube in the length direction; the suction nozzle air guide tube is above the sheet feeding plate; the cam driving shaft is in front of the vertical plate; and a moving groove is formed in each of the two side supporting plates, so that the suction nozzle air guide tube can drive the suction nozzles to cross to the position in front of the vertical plate. According to the air suction inverted twisting type single-sheet feeding device, a scattered sheet baffle plate is vertical and rod-like, the rigidity and strength can be fully guaranteed, the front ends of sheets on the sheet feeding table are horizontal and consistent, wavy concave and convex parts are avoided, and the front ends of the sheets are synchronously bent according to the amount of elastic deformation and bow tension of the sheets.

Description

technical field [0001] The invention relates to a sheet-fed paper feeding device, in particular to an air-suction inverted twist type sheet-fed paper feeding device. Background technique [0002] The paper feeding platform equipped with printing and packaging equipment such as printing machines, laminating machines, glue machines, glazing machines, die-cutting machines, scribing machines, folding machines, and collating machines has slow paper feeding speed and unstable transmission. 1. It is difficult to ensure the shortage of single-sheet paper supply, and it is often prone to double-sheet or multiple-sheet paper supply. And double or multiple sheets of paper will directly affect the later process, and bring irreparable losses. For example: when printing invoices and other printed materials with continuous ticket numbers, double or multiple sheets of paper will cause the number of the invoice to be broken, and the entire roll of invoices may be invalidated.
