Description

Fixed length paper cutting device

technical field

The utility model relates to the field of paper processing devices, in particular to a fixed-length paper cutting device.

Background technique

At present, the processing of paper is usually divided into fixed-width processing and fixed-length processing. The so-called fixed-length processing is to cut the roll paper into a certain length of paper, usually including paper feed rollers, guide rollers, and drive rollers. And the paper cutting mechanism; the roll paper is placed on the paper supply roller, passed to the driving roller through the guide roller, and then according to the intermittent work of the driving roller, it cooperates with the paper cutting mechanism to achieve a fixed length of cut paper. However, in the existing equipment, since the driving roller works intermittently, the acceleration and deceleration process of the paper during the intermittent movement is very large, and wrinkles are easily formed upstream of the driving roller, resulting in large fluctuations in the paper. Causes poor paper cutting quality, uneven length control and so on.

Further, the leveling mechanism includes a leveling frame and a sliding leveling frame that is arranged on the leveling frame and can move along the paper moving direction; the leveling frame includes two pressing rods perpendicular to the paper moving direction and two slide rails respectively arranged on both sides of the paper and in the same direction as the paper moving direction; the two slide rails and two pressing bars are connected to each other to form a square frame structure; the sliding leveling frame includes The two ends of the leveling bar are provided with sliding parts that can move and cooperate with the slide rails.

Further, the slide rail is a rack, and the sliding member is a gear; the gears on both sides are installed on the same transmission shaft, and a driving handwheel is arranged at one end of the transmission shaft.

Further, the slide rail is a slide bar, and the slide piece is a slide sleeve; the slide sleeve fits on the slide bar.

Further, the leveling mechanism can be installed on the whole platform with adjustable height through adjusting screws.

Further, the leveling frame can be installed on the whole platform with adjustable height through adjusting screws.

The beneficial effects of the utility model are: by setting a leveling mechanism upstream of the driving roller, a flat section of paper is formed on the upstream of the driving roller, so that the paper can be greatly reduced due to the presence of a flat section between the guide roller and the driving roller. Paper wrinkling, but also reduce paper fluctuations. Moreover, by setting the sliding leveling frame, the paper in the leveling section can also be manually leveled. The utility model can improve the cutting quality of the paper, and avoid the insufficient precision of the paper cutting length caused by paper folds or fluctuations.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the scope of protection of the utility model is not limited to the following specific embodiments, and those skilled in the art can make modifications, equivalent replacements, Improvements and the like should all belong to the protection scope of the present utility model.

As shown in Figures 1 to 3, the fixed-length paper cutting device described in the utility model, along the moving direction of the paper 1, sequentially includes a paper supply roller 2, a guide roller 3, a driving roller 4 and a paper cutting mechanism 5, and also includes The leveling platform 6 and the leveling mechanism 7, the leveling mechanism 7 is installed on the leveling platform 6; the leveling platform 6 is arranged on the upstream of the driving roller 4, and is positioned at the downstream of the guide roller 3; Mechanisms 7 pass through to form a smooth section 8, and the driving roller 4 is arranged at the end of the smooth section 8.

The function of the leveling mechanism 7 is to level the paper, so as to avoid wrinkling of the paper or fluctuation of the paper when the driving roller 4 works intermittently. The utility model preferably has the leveling mechanism 7 of the following structure, as shown in Figure 2 and Figure 3: the leveling mechanism 7 includes a leveling frame 71 and is arranged on the leveling frame 71 and can move along the moving direction of the paper 1 The sliding leveling frame 72; the leveling frame 71 includes two pressure rods 711 perpendicular to the moving direction of the paper 1 and two slide rails 712 respectively arranged on both sides of the paper and in the same direction as the moving direction of the paper 1; Two slide rails 712 and two pressing rods 711 are connected to each other to form a square frame structure; the sliding leveling frame 72 includes a leveling bar 721 perpendicular to the moving direction of the paper 1, and two ends of the leveling bar 721 are provided with Slide rail 712 moves a mating slider 722 .
