Next, the working principle of the flexible article coating jig 10 and the cover thereof according to the present invention will be briefly described with reference to the drawings and the first embodiment.

When the flexible article needs to be coated, the flexible article is vertically placed into the accommodating space 1110 of the supporting unit 11, the anti-roll assembly 113 in the supporting unit 11 is adjusted according to the size of the flexible article, if the flexible article is large in size, the anti-roll assembly 113 is adjusted upward along the central shaft 112, if the flexible article is small in size, the anti-roll assembly 113 is adjusted downward along the central shaft 112, or the diameter of the baffle 1131 in the anti-roll assembly 113 is changed, so that the anti-roll assembly 113 can support the upper portion of the flexible article to prevent the flexible article from being inclined toward the central shaft 112 during the process of rotating the coating film along with the supporting assembly 111.

After the flexible article is placed and the relative position between the anti-tilt assembly 113 and the flexible article is adjusted, the cover accommodating body 21 in the cover body 20 of the flexible article coating jig is covered on the outer surface of the supporting unit 11, and the cover body cover 22 is placed at the second end 2112 of the cover accommodating body 21, so that the cover body 20 of the flexible article coating jig can cover the flexible article coating jig 10 therein.

In the process of coating the flexible article, since neither end of the cover body 211 completely covers the supporting unit 11, the coating gas enters the supporting unit 11 through the gas inlet 2110 on the cover body 211 and both ends of the cover body 211, and finally reaches the surface of the flexible article in the accommodating space 1110 of the supporting unit 11. Because the cover body 211 is provided with the air inlets 2110 with different pitches and different apertures, the air flow of the coating gas entering the supporting unit 11 can be homogenized, so that the coating gas reaching the surface of the flexible article is homogenized, and the problems of uneven coating or different colors of coating on the flexible article are avoided.

Fig. 7 shows a modified embodiment of the flexible article coating jig 10 according to the first embodiment of the present invention.

Unlike the first embodiment, in the modified embodiment of the present invention, a guide groove 1120 is disposed on the central shaft 112, the baffle ring 1132 is fixed in the guide groove 1120 of the central shaft 112 and can move along the guide groove 1120, a locking member 1134 is fixed on the baffle ring 1132, and the locking member 1134 can fix the baffle ring 1132 to the central shaft 112, so that the baffle ring 1132 can move and be fixed relative to the central shaft 112, so that the anti-roll assembly 113 can provide anti-roll supporting force for flexible articles with different sizes.

Accordingly, in this modified embodiment, the baffle 1131 is also fixed in the guide groove 1120 of the central shaft 112 and can move along the guide groove 1120, and the lock 1134 is also fixed on the baffle 1131, and the lock 1134 can fix the baffle 1131 to the central shaft 112, so that the baffle 1131 can move and be fixed relative to the central shaft 112.

In this variant embodiment, the baffle 1131 and the baffle ring 1132 can be used to provide anti-tilt support force for flexible articles of different sizes, since the baffle 1131 and the baffle ring 1132 can be moved up and down and fixed relative to the central shaft 112, respectively. That is, even if the flexible objects of different sizes are coated simultaneously, the baffle 1131 and the baffle ring 1132 can provide support force for them respectively. And the locking or unlocking by the locking member 1134 can provide a convenient operation, which is time-saving and labor-saving relative to screws in adjusting and/or fixing the positions of the baffle 1131 and the baffle ring 1132.

In addition, because the baffle 1131 and the baffle ring 1132 are moved up and down along the guide groove 1120, when the baffle 1131 and the baffle ring 1132 are set to be asymmetric shapes, the up and down positions of the baffle 1131 and the baffle ring 1132 are adjusted in time, and the relative positions of the baffle 1131 and the baffle ring 1132 and the supporting unit are not changed, that is, the baffle 1131 and the baffle ring 1132 only perform axial displacement along the guide groove 1120, and radial displacement or deviation is not generated. Therefore, the working efficiency and the application range of the flexible article coating jig can be further improved by adopting the deformation embodiment of the invention.

In addition, the anti-roll assembly 113 can be connected to the central shaft 112 by any suitable means, such as screwing and fixing, or by using a combination of screwing and locking, which is within the scope of the present invention. In other words, as long as the same or similar technical solution as the present invention is adopted on the basis of the above disclosure, the same or similar technical problem as the present invention is solved, and the same or similar technical effect as the present invention is achieved, all of which belong to the protection scope of the present invention, and the specific implementation manner of the present invention is not limited thereto.
