Paper pulp moulded product die cleaning method

Abstract

The invention provides a paper pulp moulded product die cleaning method. The cleaning method comprises the following steps that the laser cleaning machine laser output average power, pulse width, repeated frequency and scanning speed are set, and fiber left on a die reaches the vaporization value through lasers; an air extraction nozzle is aligned with a laser beam acting point; the correspondingscanning manner is set according to the thickness of the fiber on a filter net; and according to the shape of a to-be-cleaned face, the motion path consistent to the shape of the to-be-cleaned face isset for the air extraction nozzle and an output head of a laser cleaning machine, and the running speed is consistent.

Description

technical field [0001] The invention relates to the field of mold maintenance of pulp molded products, in particular to a cleaning method for molds of pulp molded products. Background technique [0002] Pulp molded cushioning and shockproof packaging products (referred to as pulp molded products) are formed by vacuum-absorbing pulp on a special metal mold to form a wet blank product, and then drying, hot-pressing and trimming the formed wet blank. [0003] After a long period of production on the special metal mesh mold for pulp molding products, the metal mesh will be oxidized to a certain extent, and some fibers will be included in the interlayer, which will directly affect the quality of pulp molding products. Therefore, it is necessary to regularly check the surface of the metal mesh mold. For cleaning and maintenance, the existing cleaning methods mainly use high-pressure water gun and dry ice cleaning, which is easy to cause damage to the mold itself during the cleanin...
