Description

Rotary film coating device

This creation is related to the outer covering device applied to the film applicator, especially a rotary film applicator that is convenient to operate and can easily replace the inner film applicator.

In the early film applicators (ie correction tapes), due to the normal exposure of the front end of the applicator (such as the tongue and the tape), it is inevitable that there will be problems of sticking to the surrounding objects when retracted; and most of them are known to use a press-type linkage mechanism and A device for housing and linking the film applicator with a housing, so that when the film applicator is not in use, the application part can be hidden in the housing, and when it is to be used, the user can push the button to drive the application part out of the housing, and After use, release the button to retract the application site into the housing; however, this type of pressing device applied to the film applicator can improve the problem of exposure of the application site, but when the button is squeezed (such as stored in a pencil case) or In the event of a collision, the smeared part will still be pressed out, which will cause sticking of the material tape and even damage to the tongue plate.

In addition, the conventional outer covering device applied to the film applicator has many and complicated components used in its linkage mechanism, and the components for pushing or resetting often fail to position the film applicator firmly, which may cause internal parts to collide when shaken. Sounds cause users' troubles. Moreover, when replacing the internal film applicator in the past outer covering devices, the interlocking components will inevitably fall off.
