Preparation method of rubber roller of laminator

Abstract

The invention discloses a preparation method of a rubber roller of a laminator. The preparation method of the rubber roller of the laminator comprises the following steps: (1) cleaning and drying a metal roller core, and then coating the surface of the metal roller core with an adhesive; (2) placing the metal roller core in a mold, and wrapping the metal roller core with a foamed rubber material by adopting a press-fit forming method to form a foamed rubber layer; (3) grinding the foamed rubber layer until the thickness is uniform to obtain a semi-finished product; (4) placing the semi-finished product in a mold, and wrapping the foamed rubber layer with a non-foamed rubber material by adopting a press-fit forming method to form a non-foamed rubber layer; (5) carrying out heat treatment onthe semi-finished product treated in the step (4); and (6) further carrying out rubber surface fine grinding treatment on the semi-finished product subjected to heat treatment to obtain the rubber roller of the laminator. According to the rubber roller of the laminator prepared by the method, the contact pressure of the rubber roller of the laminator in a heating state can be effectively prevented from being greatly changed, and excellent plastic packaging can be realized through one-time roller passing.

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
