Abstract

The invention discloses a printing cutter which consists of a plurality of components, wherein the cutter can be replaced only by changing the circumference diameter of the cutter, so that the processing efficiency is improved. The cutting knife provided by the invention is composed of a plurality of components, the pair of step columns are connected through the tail ends, the round steps on the step columns are gradually increased from the tail ends to the outer ends, so that the rolling discs can be arranged on the round steps with the same outer diameter on the pair of step columns, the plurality of round steps can be provided with the rolling discs with different outer diameters, and when the cutting knife is replaced, only the rolling discs and the blades on the rolling discs are required to be replaced, so that the cutting knife is very convenient and fast, and the processing efficiency is improved.

Description

Printing cutting knife

Technical Field

The invention relates to printing equipment, in particular to a printing cutter.

Background

In ink printing products, especially printed packages, it is often necessary to perform a cutting operation after the printing is completed. The printing ink is printed by adopting an ink roller, the ink roller can complete one-time printing after finishing one-time rolling, a rolling cutting knife is arranged in front of the ink roller, the length or width dimension of product package can be measured by rolling the cutting knife for one-time rolling, the circumference diameter of the cutting knife is generally required to be set to be the length or width of a printed matter to be cut, the cutting knife cuts after measuring the dimension, and meanwhile, the following ink roller can complete printing, and the whole process realizes automatic operation. The existing cutting knife can cut printed matters with single length, and can not cut printed matters with different lengths. When the printed matter needs to be replaced, a new cutting knife needs to be replaced at the same time, the operation of replacing the new cutting knife is complex, time and labor are wasted, and the production cost is obviously increased.

Disclosure of Invention

The invention aims to provide a printing cutter which is composed of a plurality of components, and the cutter can be replaced only by changing the circumference diameter of the cutter, so that the processing efficiency is improved.

In order to solve the technical problems, the technical scheme of the invention is as follows: the printing cutter comprises a group of step columns, wherein a plurality of stepped circular steps are arranged at the outer ends of the step columns from the tail ends, and the circular steps are gradually increased from the tail ends of the step columns to the outer ends; the pair of step columns are in threaded connection through the tail ends; each round step of the step column is provided with a connecting hole respectively; a pair of rolling discs are arranged on a pair of circular steps with the same outer diameter on the pair of step columns, the side walls of the rolling discs are recessed with first radial mounting holes, and the first mounting holes are provided with first connecting bolts which can be fixedly connected with the connecting holes on the circular steps; the upper side wall of the rolling disc is provided with a clamping groove, and a pair of clamping grooves of a pair of rolling discs are provided with blades.

Further, the tail ends of the pair of step posts are in threaded connection in a clockwise direction.

Further, the first connecting hole is a threaded hole, and the first connecting bolt is a bolt.

Further, a second mounting hole corresponding to the clamping groove is recessed in the side wall of the rolling disc, and a second connecting bolt capable of abutting against the fixed blade is mounted in the second mounting hole.

Compared with the prior art, the invention has the beneficial effects that

The cutting knife provided by the invention is composed of a plurality of components, the pair of step columns are connected through the tail ends, the round steps on the step columns are gradually increased from the tail ends to the outer ends, so that the rolling discs can be arranged on the round steps with the same outer diameter on the pair of step columns, the plurality of round steps can be provided with the rolling discs with different outer diameters, and when the cutting knife is replaced, only the rolling discs and the blades on the rolling discs are required to be replaced, so that the cutting knife is very convenient and fast, and the processing efficiency is improved.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1 and 2, a printing cutter comprises a group of step columns 1, wherein a plurality of stepped circular steps 2 are arranged at the outer ends of the step columns 1 from the tail ends, and the plurality of circular steps 2 are gradually increased from the tail ends of the step columns 1 to the outer ends; the pair of step columns 1 are connected through the tail ends in a threaded manner; each circular step 2 of the step column 1 is provided with a connecting hole 3; a pair of rolling discs 4 are arranged on a pair of circular steps 2 with the same outer diameter on the pair of step columns 1, first mounting holes 5 along the radial direction are recessed in the side walls of the rolling discs 4, and first connecting bolts 6 are arranged in the first mounting holes 5 and can be fixedly connected with the connecting holes 3 on the circular steps 2; the upper side wall of the rolling disc 4 is provided with clamping grooves 7, and a pair of clamping grooves 7 of the rolling disc 4 are provided with blades 8.

The ends of the pair of step posts 1 of the present embodiment are screwed in a clockwise direction, and the clockwise screw structure is not loosened when the cutter rotates clockwise.

The first connecting hole 5 of this embodiment is a threaded hole, the first connecting bolt 6 is a bolt, and it is convenient to replace the rolling disc, and only the first connecting bolt 6 needs to be movably detached.

The side wall of the rolling disc 4 of the embodiment is recessed with a second mounting hole 9 corresponding to the clamping groove 7, and a second connecting bolt 10 capable of abutting against the fixed blade 8 is mounted in the second mounting hole 9. The blade 8 is fastened in the clamping groove 7 by the second connecting bolt 10, and the blade 8 is also detached when the rolling disc 4 is detached, so that the installation and the storage are convenient.

The cutting knife provided by the invention is composed of a plurality of components, the pair of step columns 1 are connected through the tail ends, the round steps 2 on the step columns 1 are gradually increased from the tail ends to the outer ends, so that the rolling discs 4 can be arranged on the round steps 2 with the same outer diameter on the pair of step columns 1, the plurality of round steps 2 can be provided with the rolling discs 4 with different outer diameters, and when the cutting knife is replaced, only the rolling discs 4 and the blades 8 on the rolling discs 4 are replaced, so that the cutting knife is very convenient and fast, and the processing efficiency is improved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
