Abstract

The utility model relates to a bimetal embossing roll group for an embossing machine. Convex patterns of one embossing roll is composed of a movable convex pattern sleeve which can be replaced and a press plate. Pressing patterns can be replaced, and therefore, one machine of manufacturers can be produce various paper products; the other embossing roll is provided with soft metal, and the soft metal can be replicated with concave patterns corresponding to the convex pattern embossing roll. Therefore, the paper products with clear patterns and soft texture can be pressed. After multiple times of use, the patterns on the soft metal are not clear. Clear patterns can be replicated without replacing the embossing rolls.

Description

The embossing machine bimetallic knurling rolls group of replaceable decorative pattern

The utility model relates to a kind of knurling rolls group of embossing machine.

Existing embossing machine knurling rolls group is a figuratum steel rider and wool roller knurling rolls group that partners, because the wool roller is softer, the ply of paper decorative pattern concave-convex sense of extrusion is not strong, and the repressed back of paper is soft reduces greatly, influences the paper quality of embossing.Non-exchange because of figuratum knurling rolls decorative pattern, so a machine extrusion decorative pattern is single, changes decorative pattern as need and must change knurling rolls, cause waste.

Task of the present utility model is at the deficiencies in the prior art, designs the embossing machine bimetallic knurling rolls group of replaceable decorative pattern.

The utility model is finished the work like this: the knurling rolls group is made of the knurling rolls of two metal materials, one is the steel knurling rolls of protruding decorative pattern, it is made up of knurling rolls body and decorative pattern cover, pressing plate, dog screw, another knurling rolls constitute by the steel knurling rolls with in the soft metal of knurling rolls surface setting, the soft metal is relative steel matter knurling rolls and selecting, for example aluminium, tin, lead or their alloy etc.By the bimetallic knurling rolls group of such combination, during the mutual roll extrusion of two knurling rolls, under the effect of pressure, complete being replicated on the soft metal of decorative pattern with the knurling rolls of protruding decorative pattern, two knurling rolls decorative patterns form concavo-convex die cavity about making, and during work, the gap of adjusting between two rollers is 0.2MM., can suppress 2～3 layers at every turn, more multi-layered if desired, can adjust two roller gaps and reach, can go up tangible raised and concave figures with clearly suppressing on the paper of being pressed like this.Duplicated the gap that keeps 0.1-0.3MM between two knurling rolls of decorative pattern during work, optimum value is 0.2MM, the paper flexibility during with the maintenance embossing.If use because of long-term, the pattern blurring of die flower roller also can be adjusted into 0, two roller with two roller gaps the decorative pattern that rolls protruding patterned roll is copied on the recessed patterned roll once more, reaches nonexpondable purpose.

Accompanying drawing 1 is a structure diagram of the present utility model.

Be described with reference to the accompanying drawings the utility model now: the knurling rolls group is made of the knurling rolls of two metal materials, one is the steel knurling rolls (1) of protruding decorative pattern, it is made up of knurling rolls body (2) and protruding decorative pattern cover (3), pressing plate (4), dog screw (5), and another knurling rolls (6) constitute by steel matter knurling rolls bodies (7) with in the soft metal (8) of knurling rolls surface setting.Soft metal (8) is relative steel matter knurling rolls (1) epirelief decorative pattern covers (3) and selecting, for example aluminium, tin, lead or their alloy etc.When two mutual roll extrusion of knurling rolls, with complete being replicated on the soft metal of decorative pattern of the knurling rolls of protruding decorative pattern, making up and down, two knurling rolls decorative patterns form concavo-convex die cavity.The soft metal of recessed patterned roll can the whole bag of tricks processing, for example hot-cast, plating or twine to inlay to carve in the groove of steel knurling rolls body (7) with the soft metal silk and all can.

This reality is novel compared with prior art to be had the following advantages: existing embossing machine knurling rolls group Softer because of wool roller quality, the machine power loss is bigger during embossing molding, extrusion made of paper Product produce the phenomenon that hardens, and flexibility is poor, and wool roller cost height, and this practicality is new Type is because the bimetallic knurling rolls have the working clearance, and power loss is little, and can make the paper products can Keep original flexibility; The soft metal of recessed patterned roll can repeatedly be used, and greatly reduces Cost.
