AI Technical Summary
In current cardboard box production, the offset of the creasing knife causes the cardboard box edges to become distorted, affecting the appearance, leading to market complaints and increased costs.
It adopts a die-cutting machine roller and circular die structure, and elastic sponge pressure strips are installed on both sides of the crease cutter. The height is slightly higher than the crease cutter. The relative movement of the rollers realizes the accurate forming of corrugated paper, reduces crease offset and corrugation crushing, and improves edge distortion.
It effectively reduces the distortion of cardboard box edges, lowers market complaints and rejection rates, improves forming accuracy, and saves labor costs.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to corrugated case production equipment and process technical field, especially, it relates to a device that can improve paper box edge line distortion. BACKGROUND
[0002] At present, the edge line die of paper box production plant is generally lower than the line pressing knife on both sides, the structure is just pressed to the corrugated edge valley and parallel to the corrugated paper box in ideal situation, and the edge line of paper box after forming the box will be very straight, but in actual production, the line pressing knife cannot be just pressed to the corrugated edge valley and parallel to the corrugated paper box in most cases, which will cause the line pressing deviation during die cutting, and the corrugated paper box on both sides of the line pressing cannot be pressed flat or crushed, and the vertical edge line of the paper box after forming the box will be distorted due to the line pressing deviation and the accumulation of the corrugated paper box near the edge line, from the role of packaging parts, the protection effect is not reduced, but the market demand for packaging materials is getting higher and higher, and the paper box with distorted edge line will cause complaints and rejection in domestic and foreign market sales and storage end due to the ugly appearance, and the selection and sorting will also cause the waste of paper box and the increase of overall cost. SUMMARY
[0003] Technical scheme: in order to solve the above technical problems, the utility model provides a device that can improve the distortion of paper box edge line, which comprises a die cutting machine roller one, a die cutting machine roller two, a round die structure, a line pressing knife and a pressing strip, the two ends of the die cutting machine roller one and the die cutting machine roller two are fixed on the support of the die cutting machine and installed in the structure of upper and lower parallel, the rotating directions of the two rollers are opposite, the round die structure is fixedly installed on the outer surface of the lower end of the die cutting machine roller two, the line pressing knife is installed, and a plurality of line pressing knives are distributed in the surface of the round die structure in the form of interval and parallel, wherein the two sides of the outer side wall of each line pressing knife are provided with a pressing strip, the outer surface of the pressing strip is an arc-shaped elastic structure, and the inner side surface is in abutment with the outer side surface of the line pressing knife.
[0004] As an improvement, the height d1 of the line pressing knife and the height d2 of the pressing strip are 1.01~1.1.
[0005] As an improvement, the setting direction of the line pressing knife is parallel to the rotating direction of the roller.
[0006] As an improvement, the pressing strip is a structure prepared from sponge.
[0007] Beneficial Effects: The device proposed in this utility model for improving the distortion of corrugated cardboard edges has two advantages. First, by setting the circular mold structure between two interlocking rollers, the relative movement of the rollers enables the corrugated paper to be crimped in one go, saving labor costs and improving accuracy. Second, by installing pressure strips on both sides of the crimping knife, with a height slightly greater than the height of the crimping knife, the elasticity of the sponge pressure strips and their slightly higher height allow the cardboard to be pressed firmly before crimping, reducing the degree of crimping deviation and increasing the crushing amplitude of the corrugations on both sides of the crimping knife, effectively reducing the degree of edge distortion after the box is formed.

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the examples. These examples are used to illustrate this utility model, but are not intended to limit its scope.
[0013] See Figure 1 As shown, a device for improving the distortion of carton creases includes a die-cutting machine roller 1, a die-cutting machine roller 2, a circular die structure 3, crease cutters 4, and pressure strips 5. The two ends of the die-cutting machine roller 1 and the die-cutting machine roller 2 are fixed on the support of the die-cutting machine and installed in a parallel manner, with the two rollers rotating in opposite directions. The circular die structure 3 is fixedly installed on the outer surface of the lower die-cutting machine roller 2. Multiple crease cutters 4 are installed, spaced apart and parallel to each other on the surface of the circular die structure 3. Each crease cutter 4 has a pressure strip 5 installed on both sides of its outer outer wall. The outer surface of the pressure strip 5 is an arc-shaped elastic structure, and its inner surface abuts against the outer surface of the crease cutter.
[0014] See Figures 2-3 This is a specific embodiment of the present invention. The height d1 of the creasing knife 4 and the height d2 of the creasing strip 5 are given, where d2:d1 = 1.01~1.1. Furthermore, the creasing strip 5 is designed with a structure made of sponge. This device significantly reduces the degree of twisting by optimizing the height and material of the creasing strips on both sides of the die-cutting creasing knife, improving the appearance of the television set carton and preventing complaints and rejections from domestic and international sales and warehousing ends.
[0015] In the utility model, the setting direction of the line pressing cutter 4 is parallel to the rotating direction of the roller. Embodiment
[0016] In the utility model, the height of the pressing strip is 22.5mm, and the height of the line pressing cutter is 22mm. The pressing strip is made of sponge strip with slightly soft hardness. The elasticity of the sponge pressing strip and the height slightly higher than the line pressing cutter are utilized to press the paperboard first and then press the line, so that the line offset degree is reduced, the crushing range of the corrugation on both sides of the line pressing cutter is increased, and the line distortion degree after boxing is effectively reduced.
[0017] The improved paper box obtained by the device can overcome the problems of easy line deviation and line distortion after boxing, so as to reduce the defective rate, improve the quality, reduce market complaints and rejection.
[0018] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
