Description

Technical Field

[0001] The utility model belongs to the technical field of plastic bag spraying machines and relates to an anti-wrinkle spraying machine. Background Art

[0002] Plastic bag spraying technology mainly involves the application of coatings to achieve a protective or decorative effect. Some polymers can be dissolved in some solutions to form a solution containing a transparent coating. The plastic bag can be immersed in this solution to form a transparent protective coating. The thickness of the coating can be controlled by the dipping time and the dipping temperature. This method is simple and easy, but it requires finding a coating with high adhesion and anti-scratch properties suitable for the target plastic bag. The failure of the plastic bag to remain flat during the spraying process may cause a series of problems:

[0003] Plastic bags need to maintain a certain degree of flatness when spraying so that the paint can adhere evenly to the surface. If the plastic bag is not flat, uneven coating, blistering, cracks, etc. may occur during spraying, affecting the appearance and texture.

[0004] Uneven plastic bags may cause paint to flow, spatter, and accumulate during the spraying process, resulting in uneven surfaces and even obvious defects on the finished products. These defective products need to be reworked or scrapped, increasing production costs and defective product rates. If the paint cannot be evenly covered on the surface of the plastic bag during the spraying process, it will affect the plastic bag's moisture-proof, oil-proof, and UV-proof functions. This difference in performance may cause problems during use, such as moisture, oil stains, or UV damage to the packaged items.

[0005] If the plastic bag is uneven during the spraying process, it may take several repetitions of spraying to meet the requirements, which increases production time and labor costs. At the same time, rework and scrapping will also reduce production efficiency and affect overall production capacity. If the waste and defective products generated during the production process are not properly handled, they may cause environmental pollution. At the same time, unreasonable spraying technology may also cause waste and pollution of paint, which is not in line with the green and environmentally friendly production concept.

[0006] In summary, the failure of plastic bags to remain flat during the spraying process will cause a series of problems, including poor spraying effect, increased defective rate, performance impact, reduced production efficiency and environmental issues. Therefore, an anti-wrinkle sprayer is urgently needed to solve the above problems. Utility Model Content
