As shown in fig. 12 to 16, the present application also discloses a transfer film produced based on the above transfer film production process, which comprises a roll 141, a transfer film body 13 wound on the roll 141 and having a plurality of easy-to-tear lines formed at equal intervals along the length direction, a first protection plate 15 and a second protection plate 16 respectively disposed at both ends of the roll 141 and respectively used for protecting both ends of the transfer film body 13, a connection assembly 17 disposed between the first protection plate 15 and the second protection plate 16 and used for detaching the first protection plate 15, the second protection plate 16 and the roll 141, and a clamping assembly 18 detachably disposed on the first protection plate 15 and the second protection plate 16 and used for clamping and fixing the ends of the transfer film body 13;
The clamping assembly 18 includes two elastic clamping plates 181 having one ends connected to each other, a clamping area for clamping the transfer film body 13 is formed between the two elastic clamping plates 181, and a plurality of first connection grooves 151 for connecting the two elastic clamping plates 181 and for forcing the two elastic clamping plates 181 to deform until clamping the transfer film body 13 are formed on the first protection plate 15 and the second protection plate 16 at intervals along the circumferential direction of the drum 141.
In this embodiment, the first protection plate 15 and the second protection plate are detachably connected to the two ends of the winding drum 141 through the connection assembly 17 to protect the two ends of the transfer film body 13 on the winding drum 141, so that pollution is avoided, the first protection plate 15 and the second protection plate 16 can be used for multiple times, the use cost is reduced, and meanwhile, the two elastic clamping plates 181 are connected to the first connection groove 151 to clamp the end part of the transfer film body 13.
In detail, when the transfer film is used, the two elastic clamping plates 181 are detached from the first connecting groove 151, the end part of the transfer film body 13 is taken out from the two elastic clamping plates 181, and then the transfer film body 13 is torn off through the easy-to-tear line, in addition, when the transfer film body 13 is torn off, the two elastic clamping plates 181 are connected in the first connecting groove 151 and abutted against the surface of the transfer film body 13 to limit, so that the transfer film body 13 is convenient to tear off, and when the transfer film on the winding drum 141 is used up, the first protection plate 15 and the second protection plate are detached, and then a new winding drum 141 with the transfer film body 13 can be replaced.
It should be noted that, the first connecting groove 151 is provided with a chamfer or a rounded corner which is convenient for the two elastic clamping plates 181 to slide in.
Further, as shown in fig. 13 to 15, the connection assembly 17 includes connection plates 171 provided on the first protection plate 15 at equal intervals in the circumferential direction of the roll 141, and connection rings 172 provided on the second protection plate 16 and screwed to the respective connection plates 171, and when the connection rings 172 are connected to the connection plates 171, the connection plates 171 deform and support the inner circumferential surface of the roll 141;
the inner annular surface of the connecting ring 172 is provided with a second connecting groove 173 for connecting the clamping assembly 18.
In this embodiment, through setting up go-between 172 threaded connection in a plurality of connecting plates 171, force the connecting plate 171 to take place deformation and support the interior ring face of reel 141, realize dismantling between first protection plate 15, the second board protection shield and the reel 141 and connect, easy dismounting, convenient to use, and connection stability is high, installs supporting component in second spread groove 173 simultaneously, and equipment when being convenient for production, prevent again that supporting component exposes in the transportation and easily takes place to drop outward.
In detail, during assembly, the clamping assembly 18 is connected in the second connecting groove 173, and the two connecting arms 7331 of the tightening member 733 clamp the clamping assembly 18, so that the connecting ring 172 can be rotatably connected in the connecting plate 171 along with the clamping assembly 18, and the installation is convenient.
The connection plate 171 and the elastic clamping plate 181 may be made of plastic, and have a certain strength and a certain deformability.
Further, as shown in fig. 16, the transfer film body 13 includes two transfer layers 131 disposed at intervals and patterned on the sides apart from each other, two first separation layers 132 disposed on the patterned sides of the two transfer layers 131, respectively, and a second separation layer 133 disposed between the two transfer layers 131.
In the present embodiment, the first isolation layer 132 is disposed in cooperation with the second isolation layer 133 to prevent the transfer layer 131 from being contaminated.
In detail, when in use, the first isolation layer 132 is torn off, and the pattern on the transfer layer 131 can be transferred.
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "front and rear", "left and right", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or component in question must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.
Of course, in this disclosure, those skilled in the art will understand that the term "a" or "an" is to be interpreted as "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, and in another embodiment, the number of elements may be multiple, and the term "a" is not to be construed as limiting the number.
The foregoing is merely a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions easily conceivable by those skilled in the art under the technical teaching of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
