Description

Technical Field

[0001] The utility model relates to the technical field of film coating devices, and in particular to a film coating device for a woven bag production line with a quantitative spraying function. Background Art

[0002] Coating is a process whereby the woven bag manufacturer uses special equipment or machines to apply a layer of plastic film on the surface or inside of the woven bag, which is like a super glue that only sticks to the surface or inside of the woven bag to prevent water from entering or seeping out, thus playing a good sealing role. For example, bags for flour need to be coated to prevent water from entering. Bags for feed also need to be coated to seal the feed and prevent moisture.

[0003] Most of the coating devices used in woven bag production lines in the prior art do not supply materials in a quantitative manner during use, resulting in either insufficient pre-configured materials or excessive materials causing waste during the coating process. In addition, since quantitative supply is not possible, the quality of each batch of printed woven bags is inconsistent, affecting the user experience and product image.

[0004] Therefore, a coating device with quantitative spraying function for a woven bag production line is proposed. Utility Model Content
