Description

Double coating head coating machine

technical field

The utility model relates to a coating machine with double coating heads in the protective film industry.

Background technique

The coating machine is mainly used for the coating production of plastic film surface protection adhesive tape. It is a kind of equipment that coats the rolled base material with a layer of glue with specific functions, and winds it up after drying. At present, in the protective film industry A common coating machine has a single coating head structure. When the main net coating head applies glue to the passing substrate, the coating machine with a single coating head applies uneven glue, which affects the performance and quality of the product. Especially when applying glue to wide-width substrates, the wide-width substrates are easy to discount, and the phenomenon of uneven glue coating is more likely to occur, so that the quality of the product cannot be guaranteed. In view of the above shortcomings, it is necessary to make improvements .

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a double coating head coating machine with reasonable structure, uniform glue coating and improved product quality.

The technical scheme that the utility model solves its technical problem adopts is:

Double coating head coating machine, including the main net coating head gluing machine and the pre-coating head gluing machine, the main net coating head gluing machine is equipped with a rubber plate I that can be lifted up and down, and is set above the rubber plate I There is an anilox roller, on the side of the anilox roller, there is a scraping knife Ⅰ, and an anilox rubber pressure roller is set above the anilox roller, and the anilox rubber pressure roller moves up and down through the cylinder drive device Ⅰ to make it Separated or pressed together with the anilox roller, the main screen coating head gluing machine is also equipped with a pre-coating head glue uniform roller, a main screen coating head glue uniform roller, and the pre-coating head gluing machine is equipped with an upper and lower There is a pre-coating anilox roller on the top of the rubber plate II, a scraper knife II is located on the side of the pre-coating anilox roller, and an adjustable guide roller is set on the top of the pre-coating anilox roller, which is driven by an air cylinder. The device II drives the adjustment guide roller to move up and down, and the pre-coating head gluing machine is also equipped with a guide roller.

The beneficial effects of the utility model are: During the coating process, the base material is first conveyed by the feeding device from the guide roller of the pre-coating head gluing machine. The angle position of the anilox roller is in soft contact, and the pre-coating anilox roller (the direction of rotation is opposite to the forward direction of the substrate) is used to pre-coat the substrate (coincidence gluing), and at the same time, the scraping knife II is applied to the pre-coating anilox roller The glue on the top is scraped, so that the pre-coating anilox roller can evenly glue the glue to the substrate; The same progress) first scrape off the excess glue on the substrate, after that, the substrate is sent to the anilox roller, and the anilox adhesive pressure roller directly presses the substrate so that the substrate directly touches the anilox roller and glues it Bring it in along the forward direction of the substrate, and at the same time scrape the glue on the anilox roller with the squeegee knife Ⅰ, so that the anilox roller can coat the glue on the substrate again, and finally the substrate passes through the glue uniform roller of the main screen coating head (rotating The direction is opposite to the forward direction of the base material) scrape off the excess glue on the base material again and fill in the incomplete gluing position and send it out to complete the double gluing process. After that, the product enters the dryer for drying; the utility model adopts After pre-coating and main-net gluing, the glue can be evenly coated on the substrate, especially when gluing wide-width substrates, avoiding the phenomenon of uneven coating due to easy discounts on wide-width substrates , effectively improving the quality of the product.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Detailed ways

Referring to Fig. 1, the double-coating head coating machine includes a main net coating head glue coating machine 1 and a pre-coating head glue coating machine 2, and the main net coating head glue coating machine 1 is provided with a rubber plate that can be lifted up and down Ⅰ3. An anilox roller 4 is set above the rubber disc Ⅰ3, a scraper knife Ⅰ5 is located on the side of the anilox roller 4, and an anilox rubber pressure roller 6 is set above the anilox roller 4, driven by the cylinder driving device Ⅰ7 The anilox back glue pressing roller 6 moves up and down to separate or press together with the anilox roller 4, and the main net coating head gluing machine 1 is also equipped with a pre-coating head glue uniform roller 8, a main net coating head glue Uniform roll 9, the pre-coating head gluing machine 2 is provided with a rubber disc II 10 that can be lifted up and down, and a pre-coating anilox roller 11 is arranged above the rubber disc II 10, and is located on the side of the pre-coating anilox roller 11.
