Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1, the embodiment discloses an anti-scratch coating mechanism, which includes a roller assembly and a scraper assembly, wherein the roller assembly can transmit and coat the film body 100, and the roller assembly is matched with the position limitation of the scraper 4, so that the thickness uniformity of the coating colloid 3 on the surface of the film body 100 can be effectively ensured, and the risk of scratching is avoided.

In the present embodiment, the roller assembly includes a first roller 1 disposed vertically, and a second roller 2 disposed corresponding to the first roller 1, wherein the first roller 1 is located above the second roller 2. Preferably, the first roller 1 and the second roller 2 both rotate clockwise, and a gap for the film body 100 to penetrate through is formed between the first roller 1 and the second roller 2. Wherein, the motors for driving the first roller 1 and the second roller 2 to rotate are all servo motors.

In the above arrangement, the surface of the film body 100 facing the first roller 1 can contact the surface of the first roller 1, and is further driven by the first roller 1 to perform effective conveying. The second roller 2 has the colloid 3 in a semi-solidified state on the surface thereof, and the colloid 3 in a semi-solidified state is able to contact the surface of the film body 100 while the second roller 2 continues to rotate, thereby completing the process of applying the colloid 3 in a semi-solidified state to the surface of the film body 100.

It should be noted that, in order to reduce the influence of the inertia force on the film body 100 of the semi-solidified colloid 3, the rotation direction of the second roller 2 is opposite to the conveying direction of the film body 100 in the present embodiment, which can effectively solve the above-mentioned technical problem.

In this embodiment, the scraper assembly includes a scraper element 4 and a driving element, and the scraper element 4 is disposed corresponding to the first roller 1 and is located on the left side of the first roller 1. It is noted that the scraper element 4 can be moved towards or away from the film body 100 by the driving member, so that the distance between the acting part 5 of the scraper element 4 and the surface of the film body 100 is equal. In the above arrangement, the acting part 5 of the scraper element 4 can contact the semi-solidified glue 3 coated on the film body 100 and scrape the excessive semi-solidified glue 3 off the film body 100, so that the glue 3 remained on the film body 100 has the same thickness.

It is worth noting that the action part 5 of the scraper element 4 is provided with a scraping-proof element made of nylon material, so that in the process of high-speed transmission of the film body 100, the contact stress between the scraper element 4 and the film body 100 or the colloid 3 in a semi-solidified state can be reduced, and the risk of scraping the film body 100 is further reduced.

Because the glue coating amount of different film bodies 100 in unit area has different requirements, the second roller 2 in the mode can be made of ceramic materials or steel, and the different requirements of the glue coating amounts can be effectively met through the difference of the mesh number. Wherein preferably said second roller 2 is detachably arranged on the mounting.

In this application, the mechanism further comprises a storage tank 6 for storing the colloid 3 in a semi-solidified state, the upper end of the storage tank 6 has an opening through which part of the second roller 2 can be immersed in the colloid 3 in the storage tank 6. Wherein, the bottom of the storage tank 6 is provided with a glue outlet 7 which can discharge the glue 3.

In the present application, the mechanism includes a tension roller 8 for adjusting the tension of the film body 100, the tension roller 8 being located at the front end of the first roller 1 in the conveying direction of the film body 100. The long-time conveying action may cause the loose joint between the film body 100 and the first roller 1, and the disadvantages encountered by the adjustment by the tension roller can be effectively solved.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
