Background technique

Paper cutter is a kind of cutting machine, which is widely used in paper processing. Since the production of printing, packaging, book binding, etc. from material cutting to printed finished products and the cutting of bound rough books all require paper cutters to cut, paper cutters are important equipment for paper product processing and have been widely used in printing and printing. Factory, bookbinding factory, packaging factory, paper product processing factory, etc.

At present, the transmission of paper is mainly realized by the conveyor belt, but in the actual operation process, since the conventional conveyor belt is not equipped with a limit mechanism for the paper, the paper may be shifted during the transmission process, which will affect the later cutting. The surface cut by the paper cutter is not parallel to the width direction of the paper, resulting in a high reject rate, resulting in increased input costs.

By adopting the above technical solution, when a stack of paper is conveyed on the second conveying belt, the bottom end of the paper is in rolling connection with the ball. Compared with the sliding of the bottom end of the paper on the plane of the frame, the friction force between the bottom end of the paper and the ball is small, which is convenient for paper transmission.

The utility model has the following advantages:

1. A plurality of limit mechanisms are evenly distributed on the frame, and each limit mechanism includes two symmetrically arranged limit blocks. The two limit blocks can limit the displacement of the paper on both sides along the width direction, thereby making the paper Move along the original trajectory without deviation;

2. The tensioning mechanism provided on the toothed belt makes the tension on the toothed belt equal everywhere, and then makes the toothed belt mesh with each driving part, ensuring that all the driving parts are respectively meshed with the toothed belt.

When a stack of paper is conveyed on the second conveying belt 3 , the bottom end of the paper is in rolling connection with the ball 12 . Compared with the sliding of the bottom end of the paper on the plane of the frame 1, the friction force between the bottom end of the paper and the ball 12 is small, which is convenient for paper transmission.

As shown in Figure 3, the limit mechanism 5 includes two limit blocks 51 arranged symmetrically and abutting against both sides of the paper along the width direction, and used to drive the two limit blocks 51 to approach and move away from each other in the horizontal direction. The drive assembly 52. The opposite sides of the two limiting blocks 51 are provided with placement grooves 511 , and a rotating roller 512 is installed in the placement grooves 511 , and both ends of the rotating rollers 512 are axially fixed and connected to the placement grooves 511 for circumferential rotation. The drive assembly 52 includes a two-way screw 521 that passes through the frame 1 in the horizontal direction and has a forward thread 5211 and a reverse thread 5212 in sequence, a driving member 522 for driving the two-way screw 521 to rotate, and is installed on the limit block. 51 is a limiting member 523 used to limit the rotation of the limiting block 51 , and the two limiting blocks 51 are screwed to the forward thread 5211 and the reverse thread 5212 respectively. The frame 1 is provided with a plurality of symmetrically arranged restricting grooves 13 , the restricting piece 523 passes through the two opposite restricting grooves 13 , and the two ends of the restricting piece 523 are respectively fixed on the frame 1 .
