Abstract

The utility model provides an automatic paper folding machine, comprising four rollers, positioning plates, a paper feeding box, and a paper guiding plate. A driven roller (2) driven by a driving roller (5) plays a role of paper feeding; paper guided by the paper guiding plate (3) enters into the paper feeding roller group and then enters into the positioning plates (8), (9). The terminal end of the positioning plates is blocked, and the paper under the paper feeding roller group bearing the combined action of counterforce and the component force of downward force can bend. The folding paper driven by two roller surface of the paper folding roller group can enter the paper folding roller group; paper folding is completed; the folding paper is carried out. The positioning plates (8), (9) are at the lower part of the whole paper folding machine. The utility model has the advantages of small size, high efficiency, and good paper-folding quality, which can be driven by electric or by hand.

Description

Automatic paper folding machine

The utility model belongs to office equipments, is used for the automatic folding of file paper.

The utility model is to be the layboy of agent structure by four rolls and locating plate, a lot of printing machinery of reporting in patent and other document, paper feed, printing, folding, integrated process such as bind, cut a sheet of paper are finished, paper folding is part of functions wherein just, and independent folding machine is not reported.

The utility model its objective is the manual folding that replaces file paper, reduces labor intensity, and improves office efficiency.

The external form of layboy is consulted accompanying drawing (2), its structure is consulted accompanying drawing (1), keystone configuration is initiatively roll (5) and three idle rolls (2), (4), (7) and locating plate (8) and (9), sheet feed cassette (1), lateral paper guide (3) and splicing plate (6), the mode transmission that idle roll (2) and roll (5) initiatively contact with non-roll surface, promptly by transmissions such as chain or belts, do in the same way and rotate, see all from accompanying drawing (1) and to rotate counterclockwise, idle roll (4) is the friction of rolling transmission that the roller rest face contacts with (7) with active roll (5), direction is with initiatively roll is opposite, wherein initiatively roll (5) constitutes the feeding-in roll group with idle roll (4), can send paper downwards by lateral paper guide (3); Initiatively roll (5) constitutes paper folding roller group (that is exit roller group) with idle roll (7), and its function is that crooked letterweight is converted into trace and delivers to splicing plate (6).

Locating plate (8), (9) are original bench mark with the paper feed level below four rolls, and the clockwise direction meter is in 270 ° to the 360 ° scopes, and initiatively the available motor driven of roll (5) also can be moved with hand.

The process of finishing paper folding is as follows: because the motion of idle roll (2), paper is pushed ahead by sheet feed cassette (1), turn to down to lateral paper guide (3) and to enter the paper feeding roll stacks, then enter in locating plate (8) and (9), paper is obstructed at the locating plate end, but the feeding-in roll group continues downward paper feeding, paper produces antagonistic force, and and the component combined action that moves downward of feeding-in roll group, make paper bending, and under the drive of active roll (5) and idle roll (7) two roll surfaces, entering the paper folding roller group, splicing plate (6) is finished and is sent in paper folding.

The roll surface of four rolls is with the elastomeric material of certain degree of hardness, as formations such as polysulphide rubbers, nitrile rubber, elastoplast.

Locating plate (8) and (9) employing are taken out the cover mode and are combined, and its length can be regulated arbitrarily, to adapt to the paper of different size.

The utility model volume is little, and it is low to consume energy, the efficient height, and folding line is neat, can improve office efficiency.

Claims

1, by an active roll and three layboy that idle roll is formed, its technical characterictic is that initiatively roll (5) contacts with roll surface respectively with idle roll (4), (7) and does the friction of rolling transmission, initiatively roll (5) is the powered rollers of complete machine, again and idle roll (4) constitute the feeding-in roll group; Also and idle roll (7) constitute paper folding roller group (that is exit roller group), locating plate (8) and (9) are positioned at below four rolls.
