Method and device for stress elimination of paper plastic products

Abstract

The invention relates to the technical field of pulp molding production, and in particular relates to a device for stress elimination of paper plastic products, the device for stress elimination of the paper plastic products comprises a conveyor for conveying the formed paper plastic products to a next process, and a spray humidification zone for spraying and humidifying the paper plastic products, a heating zone for heating the paper plastic products, and a cooling zone for natural cooling of the paper plastic products are in turn arranged on the conveyor along the transportation direction ofthe paper plastic products. The invention also relates to a method for stress elimination of the paper plastic products, the method for stress elimination of the paper plastic products is mainly as follows: the conveyor conveys the formed paper plastic products to the next process, and allows the paper plastic products to in turn to be sprayed and humidified in the spray humidification zone, heated and dried in the heating zone and naturally cooled in the cooling zone during transportation to eliminate the stress of the paper-plastic products so as to directly enter the paper-plastic productsto the next process. The products can be continuously produced, and the production efficiency and the output of the products are improved.

Description

Technical field [0001] The invention relates to the technical field of pulp molding production, in particular to a method and equipment for stress relief of paper plastic products. Background technique [0002] In the production process of paper-plastic products, stress relief is required after the paper-plastic products are formed. The traditional method is to use aging treatment to eliminate the stress of paper-plastic products. This method has the following defects: [0003] 1. The paper-plastic product needs to be placed for 24 hours at room temperature or under natural conditions after being formed, which results in slow production progress in subsequent processes and affects product output. [0004] 2. When the paper-plastic product is standing still, the product needs to be taken to the static area to stand, and the product needs to be taken out of the static area when the next process is carried out, which leads to an increase in manpower and material resources, increased cos...

AI Technical Summary

Problems solved by technology

[0003] 1. Paper-plastic products need to be placed at room temperature or under natural conditions for 24 hours after molding, resulting in slow production progress in subsequent processes and affecting product output

[0004] 2. When the paper-plastic product is standing still, the product needs to be taken to the standing area for standing, and the product needs to be taken out of the standing area when the next process is carried out, which leads to an increase in manpower and material resources, increases costs, and cannot continue Production, and need to increase the use of site area to increase land costs

[0005] 3. Paper and plastic products are placed in the static area, which needs to occupy a large space, and has a great impact on some products with relatively high requirements and need to be dust-free and sterile

[0006] 4. The flatness of paper-plastic products after aging treatment is not good enough, which has a great impact on product quality
