A kind of preparation method of plastic machine rubber roller

Abstract

The invention discloses a method for preparing rubber rollers of plastic laminating machines. The preparation method of the rubber roller of the plastic laminating machine comprises the following steps: (1) after the metal roller core is cleaned and dried, then an adhesive is applied on the surface of the metal roller core; (2) the metal roller core is placed in the mold , the foam rubber material is wrapped on the outside of the metal roller core by compression molding to form a foam rubber layer; (3) the foam rubber layer is ground until the thickness is uniform to obtain a semi-finished product; (4) the semi-finished product Placed in the mould, the non-foamed rubber material is wrapped on the outside of the foamed rubber layer by compression molding to form a non-foamed rubber layer; (5) heat-treating the semi-finished product processed in step (4); (6) ) After the heat treatment, the semi-finished product is further processed by fine grinding on the rubber surface to get the rubber roller of the plastic machine. The plastic laminating rubber roller prepared by the method can effectively avoid large changes in the contact pressure of the plastic laminating rubber roller in a heated state, and then can realize excellent plastic sealing by one-time laminating.

Description

technical field [0001] The invention relates to the technical field of preparation of plastic machine rubber rollers, in particular to a preparation method of plastic machine rubber rollers. Background technique [0002] Laminating machine is also called plastic sealing machine or laminating machine or laminating machine, which is a special equipment for plastic sealing photos or documents. Its working principle is to place the items to be plastic-sealed in the middle of the plastic-sealed film, and then press them together through the high temperature and pressure of the rubber rollers of the plastic machine. The items after plastic sealing are beautiful and firm, and at the same time have functions such as waterproof, anti-scratch, anti-fouling, anti-wrinkle, anti-fading, etc., which can extend the shelf life. [0003] Laminating machine rubber roller is the core component of the laminating machine, and the quality of plastic sealing is closely related to the laminating m...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the technical deficiencies in the prior art that the plastic laminating machine cannot achieve excellent plastic sealing by one-pass rolling, and reduce the deterioration of the plastic sealing effect caused by voltage and frequency differences in different countries; provide a plastic laminating machine glue Method of making the roll

[0005] In the research, the present invention finds that the reason why the plastic laminating machine in the prior art cannot achieve excellent plastic sealing by one-pass roller is that the existing plastic machine rubber rollers often only have one layer of rubber roller material, and the volume of one layer of rubber roller material when heated The change is large, resulting in a large change in the contact pressure under heating; and the existing rubber rollers of plastic machines cannot adapt to the changes in contact pressure brought about by voltage and frequency differences in different countries; thus, it is impossible to achieve excellent plastic sealing through one pass
