A coating mold with quick cleaning function

Abstract

The invention discloses a laminating mold with quick cleaning function. Its structure includes a laminating mold, a sealing briquetting block, a guide frame, a guide hand wheel, and a transmission screw rod. The laminating mold is composed of a mold body, a laminating compression flow channel, The cleaning mechanism, the die head flow channel, the feeding installation flange, the heating plate, and the recovery box are composed. The cleaning mechanism is isolated from the laminating compression flow channel by using the sealing isolation insert, so as to prevent the laminating material from penetrating into the cleaning mechanism when it flows. The magnetic field is driven by the magnetic field ring to cooperate with the armature to attract the magnetic field, so as to drive the moving roller to move, and use the pusher to clean out the residual impurities in the coating compression flow channel, and then stick some small particles through the sticky ring to prevent the particles from entering the coating. The film head will block the mold opening, resulting in uneven coating of the product, or even cracking. This design improves the stability and repeatability of the laminating mold cleaning work.

Description

technical field [0001] The invention relates to the field of molds, in particular to a coating mold with a quick cleaning function. Background technique [0002] Laminating refers to using a laminating machine to spray a layer of polyethylene or polypropylene with a thickness of 0.01-0.07mm on the surface of the cardboard, so that the air tightness and tensile strength of the cardboard are better improved, and at the same time, the cardboard’s Moisture-proof, water-proof, oil-proof and dirt-proof properties have been greatly improved. In recent years, with the continuous prosperity of the market economy, there will be more and more demand for coated paperboard for liquid beverages, solid frozen foods and other products, and the technology of coating is becoming more and more mature. According to the use characteristics of the product, the coating processing of the cardboard can be single-sided or double-sided. For double-sided coated cardboard, printing quality control is ...

AI Technical Summary

Problems solved by technology

For double-sided coated cardboard, printing quality control is very important. If the process is not properly controlled, it is prone to the quality problem of overprinting. The coating of the product is uneven, or even cracked. The ink is printed on the non-absorbent PE coating, which is easy to stick to the back of the printed product, and the coating mold is cleaned manually. The effect is quite good, but it takes a lot of time and manpower. , so we need a coating mold that can be cleaned quickly
