Description

High-speed cutting device of paper

Technical Field

The utility model relates to a printing machine technical field especially relates to a high-speed cutting device of paper.

Background

At present, the cut-off knife of using on digital ink jet printer is generally all bulky, and the adjustment of cut-off knife is also inconvenient with the change, still can not cut the paper of short, simultaneously because the cutting edge generally adopts flat sword, does not have the angle, whole cutting edge is simultaneously with the paper contact completion paper cutting action, so easy wearing and tearing, life is shorter, need servo motor and speed reducer to provide powerful power in addition in the use, consequently the noise is also bigger when cutting.

SUMMERY OF THE UTILITY MODEL

Based on the problem, the utility model aims to provide an installation is dismantled conveniently, and the noise is little, and long service life rotates through the roller axle, and servo motor provides the high-speed cutting device of paper that less power just can accomplish the cut paper action.

Aiming at the problems, the following technical scheme is provided: a high-speed cutting device of paper which characterized in that: including bottom plate, hob shaft and lower blade holder, the both ends of bottom plate are equipped with vertical relative backup pad, install in the backup pad at the both ends of lower blade holder, the upper end installation of lower blade holder is equipped with cutting edge up lower cutter, the both ends of hob shaft are rotatable install in the backup pad and with lower cutter from top to bottom corresponding setting, the winding is equipped with the hobbing cutter on the outer peripheral face of hob shaft, the cutting edge of hobbing cutter is the heliciform around the axial of hob shaft and distributes, the cutting edge of hobbing cutter contacts and forms the cutting edge of cut-off paper at the hob shaft rotation in-process with the cutting edge of lower cutter.

The utility model discloses further set up to, the angle that the cutting edge spiral setting of hobbing cutter was between the both ends of hobbing cutter axle is 8-10 degrees.

The utility model discloses further set up to, the hob shaft passes through the servo motor drive and rotates.

The utility model has the advantages that: the cutting edges of the hob cutters in the high-speed paper cutting device are spirally distributed on a hob shaft at an angle of 8-10 degrees, and the cutting edges of the hob cutters are in contact with the cutting edge of the lower cutter to form the cutting edges of the paper cutting; when paper is cut, the servo motor drives the hob shaft to rotate, when the front end of the cutting edge of the hob contacts the paper, the hob shaft continuously rotates for 8-10 degrees to complete the paper cutting action, compared with the traditional cutter without angles, the paper cutting machine can cut at high speed, can complete the paper cutting action only by providing power with smaller power by the servo motor and the speed reducer, and has smaller noise; the bottom plate, the hob shaft and the lower tool holder are fixedly connected through screws, and when the cutting edges are worn, the bottom plate, the hob shaft and the lower tool holder are convenient to detach, adjust, replace and maintain, and the service life of the whole device is prolonged.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-3, a high-speed cutting device for paper comprises a bottom plate 1, a hob shaft 2 and a lower knife holder 3, wherein two ends of the bottom plate 1 are provided with vertically opposite supporting plates 4, two ends of the lower knife holder 3 are installed on the supporting plates 4, the upper end of the lower knife holder 3 is provided with a lower knife 5 with an upward cutting edge, two ends of the hob shaft 2 are rotatably installed on the supporting plates 4 and are vertically arranged corresponding to the lower knife 5, a hob 6 is wound on the outer peripheral surface of the hob shaft 2, the cutting edge of the hob 6 is spirally distributed around the axial direction of the hob shaft 2, and the cutting edge of the hob 6 is in contact with the cutting edge of the lower knife 5 in the rotation process of the hob shaft 2 and forms a cutting edge of the paper. Further, as shown in fig. 2 and 3, the cutting edge of the hob 6 is spirally arranged at an angle of 8-10 degrees between the two ends of the hob shaft 2. The hob shaft 2 is driven to rotate by a servo motor.

In the structure, the cutting edges of the hob cutters 6 are spirally distributed on the hob shaft 2, and the cutting edges of the hob cutters 6 are contacted with the cutting edge of the lower cutter 5 to form the cutting edge for cutting paper; when paper is cut, the servo motor drives the hob shaft 2 to rotate, when the front end of the cutting edge of the hob 6 contacts with the paper, the hob shaft continues to rotate for 8-10 degrees to complete the paper cutting action, compared with the traditional cutter without an angle, the whole cutting edge simultaneously contacts with the paper to complete the paper cutting action, the high-speed cutting can be performed, the paper cutting action can be completed only by providing power with smaller power by the servo motor and the speed reducer, and the noise is greatly reduced; bottom plate 1, hob axle 2 and lower blade holder 3 pass through screw fixed connection, and when the cutting edge wearing and tearing back, convenient to detach, adjustment, change and maintenance increase the life of whole device.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations of the above assumption should also be regarded as the protection scope of the present invention.
