A storage device and its working method

Abstract

A storage device is characterized by comprising a synchronous transmission device, storage rollers, fixed conveying rollers, a connecting plate and a linear guide bar. The synchronous transmission device is connected with the connecting plate, the connecting plate and the linear guide bar are in clearance fit through a guide groove, the storage rollers are mounted on the connecting plate, and the fixed conveying rollers mounted below the connecting plate are fixed on a wall plate together with the linear guide bar. The operating method of the storage device includes that when in need of feeding, the synchronous transmission device drives the connecting plate and the storage rollers to move linearly to the feeding direction; and after the process is completed, the synchronous transmission device drives the connecting plate and the storage rollers to move linearly to the storage direction. The storage device has the advantages that the storage device is capable of moving linearly back and forth without speed difference to realize storage and feeding, is better in effect during hot stamping or cold stamping, free of width limits during linear moving, more stable in control due to linear moving, has a counter-tensioning function so that stamping materials are saved and wide-width process can be completed.

Description

(1) Technical field: [0001] The invention is suitable for printing machinery, especially for hot stamping machines and cold stamping machines of printing machinery, that is, a material storage device and its working method. (two) background technology: [0002] With the market's increasing requirements for packaging, more and more commodity packaging adopts hot stamping technology, especially large-scale hot stamping. The graphics and texts stamped by anodized aluminum can show a strong metallic luster, bright colors, and eternal. It does not fade, so that the product has a high-end feeling and gives people a beautiful enjoyment. Therefore, the hot stamping effect is good, the hot stamping registration accuracy is high, and the large format hot stamping has become the basic condition for high-end packaging. The quality of hot stamping effect, the accuracy of hot stamping registration, and whether it can do large-format hot stamping are inseparable from the material storage ...

AI Technical Summary

Problems solved by technology

However, with the increase of the swing angle, the tangential speed of the swing rod will change more and more, and the speed control of the feeding material will be inaccurate, which will cause the speed of the material and the substrate to be out of sync, which will affect the hot stamping effect.

At the same time, due to the limited swing angle of the pendulum, the length of material storage and feeding will not be too long, resulting in the inability to do large-format bronzing process

When the existing equipment is used for large format, the anodized aluminum and the paper are basically run synchronously. There is no anodized aluminum reverse pull mechanism, and the waste of anodized aluminum is extremely serious.
