Abstract

The invention relates to a paper cutting device, which comprises a frame, an unwinding roller, a knife roller with knife grooves, a cross bar, a knife disc arranged on the cross bar, a main rotating roller, an auxiliary rotating roller, a motor and a winding machine. Roller, both sides of the frame are provided with a horizontal first chute higher than the main rotating roller, and two first sliders are embedded in the first chute, and the first slider is equipped with a device to limit the falling of the paper roll. the limit rod; the first slider also has a vertical slot for the limit rod to slide up and down; both sides of the frame are provided with a square ring connecting frame for the two limit rods on the same side to pass through. The lower inner wall of the lower inner wall is provided with a plurality of inclined blocks, and the height of the inclined blocks gradually increases toward the nearest end of the connecting frame; the upper inner wall of the connecting frame is erected with a plurality of vertical plates, and the vertical plates and inclined blocks are arranged alternately up and down to form a zigzag channel. This solution not only skillfully prevents the paper roll from falling between the main rotating roller and the auxiliary rotating roller, but also effectively ensures the smooth winding of the base paper.

Description

technical field

[0001] The invention relates to the technical field of paper production, in particular to a paper cutting device. Background technique

[0002] The technological process of paper production is as follows: pulping→pulping→forming→drying→creping→rolling paper→base paper→rewinding. The rewinding includes three steps of unwinding the base paper, cutting the base paper and rolling up the base paper again. The function of rewinding mainly includes (1) cutting off the burrs of the base paper; (2) because the diameter and width of the base paper are large, the large roll of base paper can be cut into several rolls by a slitting device and rolled up again. Small paper rolls that meet the specifications are beneficial for subsequent processing to form finished products, and the most commonly used processing equipment in the rewinding process is the paper cutting device.

[0003] Such as Figure 5 , shown in the figure is a paper cutting device, including a frame 1, a...
