Embodiment 1

[0029] 1) The raw material is beaten, the pulper is filled with water, the raw wood pulp is added, the motor is started for hydrolysis, the pulping time is set to 8 minutes, and the pulping concentration is guaranteed to be 5%;

[0030] 2) Adding additives, the slurry after beating is screened out by a vibrating screen to remove impurities in the wood pulp, and alkyl ketene polymer waterproofing agent, corn starch, and dehydration synergist are added in the thick stock tank. The three additives account for the total formula. The mass percentage content is: 1%, 5%, 0.5%, and the slurry is adjusted to a uniform level, and then supplied to the homogenization tank through a slurry pump;

[0031] 3) For slurry forming, select the fruit holder mold, install the mold on the press, set the suction time to 1.7s, the dehydration time to 8s, the mold passing time to 1s, and the demoulding time to 0.2s, and then the homogenate is directly supplied Forming machine, the forming machine uses...

Embodiment 2

[0036] 1) Beat raw materials, inject water into the pulper, add raw wood pulp boards, start the motor for hydraulic disintegration, set the pulping time to 8 minutes, and ensure that the pulping concentration is 7%;

[0037] 2) Adding additives, the slurry after beating is screened out by a vibrating screen to remove impurities in the wood pulp, and alkyl ketene polymer waterproofing agent, corn starch, and dehydration synergist are added in the thick stock tank. The three additives account for the total formula. The mass percentage content is: 3%, 8%, 0.8%, and the slurry is adjusted to uniformity, and then supplied to the homogenization tank through the slurry pump;

[0038] 3) Slurry supply molding, select the load-bearing tray mold, install the mold on the press, set the slurry suction time to 1.7s, the dehydration time to 8s, the mold passing time to 1s, and the demoulding time to 0.2s, and then the homogenate is directly supplied Forming machine, the forming machine uses...

Abstract

The invention discloses a process for producing a logistics tray. The process sequentially comprises the following steps of: pulping raw materials, adding accessory ingredients, molding pulp, drying, thermally pressing and integrating, and inspecting and packaging, namely pulping the raw materials by using a pulper, screening out impurities from wood pulp through a vibrating screen, adding the accessory ingredients, mixing the pulp until the pulp is uniform, arranging a die on a pressure machine, supplying the uniform pulp to a molding machine, performing absorption molding by using negative pressure generated by a vacuum pump and drying a molded wet blank, performing thermal pressing and integration, and finally inspecting the product and packing the product into a storehouse. The process has the advantages that: the produced logistics tray has light weight, high quality and low storehouse capacity and can be piled up and has higher strength, shock absorption property, air permeability, moisture resistance and the like; the production raw materials are rich, have low cost and can be recycled; furthermore, the automation degree of the production process is high, and scale production can be realized conveniently.

Description

technical field [0001] The invention relates to a production process of a logistics tray. Background technique [0002] As a commonly used packaging tool, pallets are widely used in the cushioning packaging of fragile products such as industrial instruments, electronic components, household appliances and daily appliances. Commonly used packaging materials mainly include plastic, paper, glass, metal, etc. Due to the short service life and large amount of packaging materials, especially plastic chemical composite products are not easy to recycle after being discarded, and are not easy to degrade by themselves, causing environmental pollution; plastic film The low recovery rate causes white pollution, and when incinerated, it releases chemicals that destroy the ozone layer, causing air pollution and aggravating the greenhouse effect. Too much and excessive packaging aggravates the process of environmental pollution and ecological damage. In order to protect the living enviro...
