Paper-plastic tableware spraying device and technology

Abstract

The invention discloses a paper-plastic tableware spraying device and technology. The spraying device comprises a feeding module, a spray module and a spinning module which are connected through a transfer mechanism from left to right in sequence, wherein the feeding module is used for conveying to-be-processed paper-plastic tableware to the spray module; the spray module is used for spraying water-proof and oil-proof paint to the paper-plastic tableware conveyed from the feeding module from top to bottom; the spinning module is used for spinning the paint accumulated on the surface of the paper-plastic tableware to be uniform, and recycling the paint which are thrown out. According to the spraying device, the extra accumulated paint is thrown out through the spinning module, the paint layer on the surface of the product is smooth and even, the situation that a lot of paint spatters or produces fog in air during spraying can be prevented, the paint can be recycled, and the paint utilization rate is increased. The extra paint is recycled through a recycling water tank arranged on the bottom of a conveying belt, little cost is increased, the recycled extra paint can be reused, and pipelined production can be achieved, and the spraying device has the advantages of being high in production and production rate, and the like.

Description

technical field [0001] The invention relates to the technical field of paper-plastic tableware processing, in particular to a paper-plastic tableware spraying equipment and process. Background technique [0002] At present, it is generally to add water-repellent and oil-repellent to pulp to realize the waterproof and oil-proof effect of paper-plastic tableware. However, the anti-oil agent contains fluorine and its organic substances, which will cause great harm to the natural environment and human health. European and American countries are legislating to ban the use of fluorine-containing products in packaging. At present, there is no other non-fluorine oil repellent that can replace the existing oil repellent and put into use, so at present, the process is basically achieved by surface spraying to achieve the effect of waterproof and oil repellent. [0003] The Chinese utility model patent with the authorized announcement number CN2362597Y discloses a multifunctional aut...

AI Technical Summary

Problems solved by technology

[0005] (1) Due to the rough and porous surface of the paper-plastic tableware, if the current spraying method is to ensure that the paper-plastic tableware achieves the waterproof and oil-proof effect, it is necessary to use excess spraying (the material is excessively covered on the surface of the product), which will cause the bottom Accumulation, after drying, it is impossible to achieve a uniform and beautiful surface effect, such as color cast, foaming, etc.;

[0006] (2) The current spraying technology uses airless spray gun high-pressure spraying or air spray gun for spraying. These two spraying methods will cause a large amount of splashing / fogging of the paint in the air, making it difficult to recycle the paint and the paint utilization rate is low;

[0007] (3) The current spraying technology will produce a large amount of flying fog in the spraying process. If there is no absorption and discharge device, it will pollute the environment of the production workshop and damage the health of the on-site personnel.

And to set up the absorption device will not only increase the equipment cost, but also the absorbed atomized paint cannot be recycled
