Abstract
Description
Technical Field
[0001] The utility model relates to paper processing equipment, in particular to a transverse paper cutter. Background Art
[0002] A cross-cutting machine is a machine that cuts a whole roll of paper or film into sheets. Generally, a cross-cutting machine includes two front and rear traction mechanisms and a cross-cutting mechanism, and some also include a longitudinal cutting mechanism. The longitudinal cutting mechanism cuts the paper into strips in the longitudinal direction, and the cross-cutting mechanism cuts the paper in the transverse direction. The rear traction mechanism pulls the paper off the roll, and then passes through the feeding roller to the front traction mechanism. The front traction mechanism pulls the paper forward. The cross-cutting mechanism is located on the rear side of the front traction mechanism, and the longitudinal cutting mechanism is located on the front side of the front traction mechanism. Under the traction of the front traction mechanism, the paper is first cut longitudinally and then cut transversely. Since the longitudinal cutting mechanism is located on the rear side of the front traction mechanism, there are many feeding rollers on one side of the longitudinal cutting mechanism, so workers cannot come to the opposite side of the longitudinal cutting mechanism to replace, repair or adjust the longitudinal cutting mechanism. They can only squeeze in to operate, which is very inconvenient. Summary of the invention
[0003] In view of the deficiencies in the prior art, the utility model innovatively provides a top-feeding cross-cutting machine with an operating space.
[0004] A top-feed cross-cutting machine comprises a frame, a rear traction mechanism, a cross-cutting mechanism and a front traction mechanism, wherein the cross-cutting mechanism is located at the front side of the front traction mechanism, and is characterized in that an operating space accessible to people is provided between the front traction mechanism and the rear traction mechanism, a feed mechanism is installed on the frame, the feed mechanism is located above the operating space, the feed mechanism comprises a negative suction plate, and a plurality of negative suction holes which can be connected to a negative pressure source are distributed on the upper surface of the negative suction plate.
[0005] A paper pressing mechanism is installed on the frame, and the paper pressing mechanism includes a paper pressing board and a paper pressing power source for driving the paper pressing board to move up and down. The paper pressing board is located above the negative suction plate, and the paper pressing board can press the paper on the negative suction plate.
[0006] A longitudinal cutting mechanism is provided on the rear side of the front traction mechanism, and the longitudinal cutting mechanism includes a longitudinal cutting knife and a lower circular knife for cooperating in cutting. The longitudinal cutting knife is installed on the longitudinal cutting knife shaft, and the lower circular knife is installed on the lower circular knife shaft. The longitudinal cutting knife shaft is located on the rear side of the lower circular knife shaft.
[0007] The cross-cutting mechanism comprises an upper cross-cutting knife and a lower cross-cutting knife for cooperating with cutting.

[0016] Figure 5 It is a three-dimensional diagram of the cross-cutting mechanism. DETAILED DESCRIPTION
[0017] like Figure 1 and Figure 2 As shown, the top-feed crosscutting machine includes a frame 1, a rear traction mechanism 2, a crosscutting mechanism 8 and a front traction mechanism 7. The rear traction mechanism 2 can pull the paper off the roll, and the front traction mechanism 7 can transport the paper forward. Figure 2 As shown, the cross-cutting mechanism 8 is located at the front side of the front traction mechanism 7, and the cross-cutting mechanism 8 can cut the paper. In order to facilitate workers to enter the machine, as shown in FIG. Figure 1 As shown, there is an operating space 10 between the front traction mechanism 7 and the rear traction mechanism 2, and a material feeding mechanism is installed on the frame 1. The material feeding mechanism is located above the operating space 10, so that workers can easily enter the operating space 10 and come to the bottom of the material feeding mechanism to operate. Figure 1 As shown, the feeding mechanism includes a negative suction plate 3, and a plurality of negative suction holes that can be connected to a negative pressure source are distributed on the upper surface of the negative suction plate 3. When the paper comes out from the rear traction mechanism 2 and comes to the top of the negative suction plate 3, the negative suction holes on the negative suction plate 3 generate negative pressure to absorb the paper, so that the paper can be completely attached to the negative suction plate 3 and move forward stably, which can ensure the cutting accuracy of the subsequent longitudinal and transverse paper cutting and prevent the paper from having rough edges or cutting deviations.
[0018] In order to further improve the stability of paper feeding, a paper pressing mechanism 4 is installed on the frame 1. Figure 3 As shown, the paper pressing mechanism 4 includes a paper pressing paper 41 and a paper pressing power source 40 for driving the paper pressing paper 41 to move up and down. Figure 1As shown, the paper pressing plate 41 is located above the negative suction plate 3, and the paper pressing plate 41 can press the paper onto the negative suction plate 3. The lower surface of the paper is sucked by the negative suction plate 3, and the upper surface of the paper is pressed by the paper pressing plate 41, so that the paper does not float up and down, and the stable transportation of the paper is fully guaranteed.
[0019] like Figure 2 As shown, a longitudinal cutting mechanism 6 is provided on the rear side of the front traction mechanism 7. Figure 4 As shown, the longitudinal cutting mechanism 6 includes a longitudinal cutting knife 60 and a lower circular knife 61 for cutting. The longitudinal cutting knife 60 is installed on a longitudinal cutting knife shaft 62, and the lower circular knife 61 is installed on a lower circular knife shaft 63. The longitudinal cutting knife shaft 62 is located at the rear side of the lower circular knife shaft. The longitudinal cutting knife 60 and the lower circular knife 61 cooperate to cut the paper into strips. Since the longitudinal cutting knife 60 and the lower circular knife 61 are arranged in front and back positions, the paper scraps will fall directly to the ground and will not fall on the longitudinal cutting knife 60 and the lower circular knife 61, ensuring that the longitudinal cutting mechanism 6 is more stable.
[0020] like Figure 5 As shown, the cross-cutting mechanism 8 includes a cross-cutting upper knife 80 and a cross-cutting lower knife 81 for matching cutting. By the cross-cutting upper knife 80 and the cross-cutting lower knife 81 being tangent, the paper can be cut off.
[0021] In order to guide the paper to the negative suction plate 3 and to guide the paper out from the negative suction plate 3, as shown in FIG. Figure 2 As shown, guide rollers 5 are installed on both sides of the negative suction plate 3. The guide rollers 5 at the rear can smoothly guide the paper to the upper surface of the negative suction plate 3, and the guide rollers 5 at the front can smoothly guide the paper downward from the negative suction plate 3.
[0022] Finally, it is worth mentioning that the front traction mechanism 7 includes a front traction roller group and a front traction power source, and the front traction power source drives the front traction roller group to perform traction. The rear traction mechanism 2 includes a rear traction roller group and a rear traction power source, and the rear traction power source drives the rear traction roller group to perform traction. Of course, the front traction power source and the rear traction power source can be the same power source.
