Description

Oilproof paper folding machine Technical Field The utility model relates to a paper extraction folding machine, in particular to an oil-proof paper folding machine. Background The utility model discloses a chinese utility model publication No. CN222714751U discloses bottom paper extraction folder, and paper passes through between two paper folding rollers, and the side of two paper folding rollers all is equipped with V groove and the lower blade that the interval set up, and lower blade is pressed this part paper into the V groove of paper folding roller, V groove and negative pressure chamber intercommunication, and the paper laminating is at the surface of paper folding roller, accomplishes folding, but the paper extraction of materials such as oil-proof paper, aluminium foil paper, waxing paper can't be through negative pressure absorption subtended paper, folds. Disclosure of utility model In view of the technical problems in the background art, the utility model aims to provide the oilproof paper folding machine, the paper inserting knife presses part of paper between the fixed block and the paper clamping block, the cam drives the paper clamping block to clamp the fixed block, the paper can be reliably clamped, and the folding effect is good. In order to solve the technical problems, the oil-proof paper folding machine comprises a paper feeding assembly, a paper cutting assembly, a paper folding assembly and a shifting fork, wherein the paper cutting assembly is connected with the paper feeding assembly and is positioned between the two groups of paper feeding assemblies, the paper folding assembly is arranged below the paper cutting assembly and comprises two mutually matched folding rollers, an inserting assembly and a positioning assembly are alternately arranged on the periphery of each folding roller, the inserting assembly is matched with the positioning assembly, the shifting fork is arranged on the discharging side of the paper folding assembly, the shifting fork is used for pressing down materials, the inserting assembly comprises a paper inserting knife, the paper inserting knife is arranged on the folding rollers in a swinging mode, a first elastic piece is arranged between the paper inserting knife and the folding rollers, the positioning assembly comprises a fixing block and a paper clamping block which are mutually matched, the paper clamping block is arranged on a paper clamping installation shaft, the paper clamping installation shaft is rotatably arranged on the folding rollers, and the paper clamping installation shaft is connected with a driving arm and is provided with a cam.
