AI Technical Summary
Existing printing slitting machines have difficulty effectively separating the cutting area from the printing area of label printing products, resulting in increased substrate consumption and inability to reduce costs.
A novel printing slitting tool assembly is designed, employing an upper and lower tool holder. Each tool holder is equipped with two coaxial blades, and a gear transmission system enables precise cutting. The blade spacing is reduced to the millimeter level, allowing simultaneous cutting of the cutting area and the printing area.
This allows for printing more rows of labels on the same substrate, reducing substrate waste and lowering costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the printing field, and in particular to a novel printing slitting tool set. Background Technology
[0002] In the printing industry, slitting machines are commonly used to cut printed thin products into strips. A slitting machine, also called a cutting machine, typically consists of an upper and lower blade holder. The blades on the upper and lower blade holders cut the conveyed thin product apart by their relative positions. For the upper blade holder, the blades are mounted on a blade shaft via a blade holder. The blade holder has an open design similar to a clamp structure and is equipped with a locking bolt. Loosening the locking bolt allows the blade holder to slide on the blade shaft; tightening the locking bolt locks the blade holder onto the blade shaft, causing the blade holder to rotate with the blade shaft, which in turn drives the blades to rotate and cut the printed thin product.
[0003] Currently, the industry standard allows only one blade to be installed on a single blade holder, and the holder occupies a certain width, thus easily enabling the cutting of an entire printed sheet into multiple strips. However, for label printing, a row of labels typically has blank cutting areas on both sides. Existing blades can only separate the labels column by column, but cannot separate the blank cutting areas from the printing area. Figure 3 As shown in the diagram, the dashed line represents the cutting trajectory, and the white area represents the cutting zone. Furthermore, using existing cutting tools, a relatively wide area needs to be left in the cutting zone for stable cutting, which increases the consumption of printing substrate and prevents cost reduction. Utility Model Content
[0004] The purpose of this application is to provide a novel printing slitting tool assembly, which aims to solve the problems existing in the prior art.
[0005] This application provides a novel printing slitting tool assembly, including an upper tool holder and a lower tool holder. The upper and lower tool holders are rotatably connected to side baffles at both ends. The upper tool holder includes an upper tool shaft, upper blades, and an upper tool seat. The upper tool seat is slidably mounted on the upper tool shaft, and a blade groove is provided on the side of the upper tool seat. There are two upper blades, coaxially mounted in the blade groove, with a washer installed between the two upper blades. A pressure spring is installed on the outer periphery of the washer. A retaining spring is installed on the outer side of the upper blade.
[0006] Furthermore, the lower tool holder includes a lower tool shaft, a lower blade, and a lower tool seat; the lower tool seat is slidably mounted on the lower tool shaft, and the lower blade is mounted on the lower tool seat. The lower blade is positioned corresponding to the upper blade. A pad is also slidably mounted on the lower tool shaft, and the pad is located on the side of the lower tool seat. The outer diameters of the lower blade, the lower tool seat, and the pad are all equal.
[0007] Further, one end of the upper cutter shaft is provided with a first gear, and the other end is rotatably connected to the other side baffle; one end of the lower cutter shaft is provided with a second gear, and the other end is rotatably connected to the other side baffle; the first gear is in meshing connection with the second gear and is in driving connection with the external motor.
[0008] Further, the upper support rod and the lower support rod are fixedly connected between the two side baffles and are diagonally distributed on the side baffles; the lower support rod is provided with a scale.
[0009] Further, the interval between the two upper blades on the same upper blade seat is 5mm; and the diameter of the blade pressing spring is less than 5mm.
[0010] The utility model discloses the beneficial effects are: the utility model discloses two blades on a blade seat, can make the interval of blade reduce to millimeter level, not only can the printed matter be divided into strips, but also can cut off the cutting area and the printing area at one time, for example Figure 4 As shown, the dotted line is the cutting track. Because the blade can cut narrower, the cutting area can also be smaller when printing, and more columns of labels can be printed on the same base material, thereby reducing the loss of base material and reducing the cost.

DETAILED DESCRIPTION
[0017] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the present utility model.
[0018] As Figure 1 indicated in the novel printing slitting cutter set, including upper tool rest and lower tool rest. Specifically, the upper tool rest and the lower tool rest both ends are rotatably connected with side baffle 1, the upper tool rest includes upper tool shaft 2, upper blade 3 and upper tool seat 4, the upper tool seat 4 is slidably arranged on the upper tool shaft 2, the side of the upper tool seat 4 is provided with blade slot 5. The structure of the upper tool seat 4 is the same as the existing one, the difference lies in that the length of the blade slot 5 is increased, therefore the function of the upper tool seat 4 in the present utility model is the same as the function of the conventional upper tool seat 4, both including sliding along the upper tool shaft 2 and locking. The upper blade 3 is two, two upper blades 3 are coaxially installed in the blade slot 5, as Figure 2 indicated, a gasket 6 is installed between the two upper blades 3, the outer periphery of the gasket 6 is installed with a blade pressing spring 7.
