[0009] A positioning mechanism is provided in the cylinder cover and is used to support the film roll;

[0010] When the cap flips from the open position to the closed position, the positioning mechanism gradually approaches the film roll to lift it up and suspend it inside the roll.

[0011] As described above, in a film-coating device, the positioning mechanism includes a positioning cone, a connecting shaft connected to the positioning cone, and a rotating handle connected to the connecting shaft. The positioning cone and the rotating handle are located on the inner and outer sides of the cylinder cover, respectively.

[0012] In the film coating device described above, the positioning mechanism further includes a bearing disposed between the connecting shaft and the cylinder cover.

[0013] As described above, in a coating device, the positioning mechanism further includes a bushing disposed inside the cylinder cover, the bushing having a mounting cavity for the bearing to be embedded in, the bushing being connected to the cylinder cover to confine the bearing within the mounting cavity.

[0014] In the film coating device described above, a spring is provided between the positioning cone and the connecting shaft, so that the positioning cone can move relative to the connecting shaft along the axial direction of the connecting shaft.

[0015] As described above, in a film coating device, one end of the positioning cone is provided with a conical surface for insertion into the film roll, and the other end is provided with an inner cavity for mounting the spring. The connecting shaft is provided with a sliding groove, and the positioning cone is provided with a positioning pin that passes through the sliding groove.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a locking mechanism 96 for locking the cap 94 in the closed position. After the locking mechanism locks the cap, the positioning cone can maintain support for the film roll.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking mechanism 96 includes a locking pin 961 disposed on the cylinder cover 94, a locking buckle 962 hinged to the cylinder body 921, and a locking knob 963 threadedly connected to the cylinder body 921. When the cylinder cover 94 is in the closed position, the locking buckle 962 rotates to engage with the locking pin 961, and the locking knob 963 presses the locking buckle 962 to restrict its rotation.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking mechanism 96 further includes a support member 964 disposed on the cylinder body 921. The support member 964 is provided with a guide ramp 965. When the cylinder cover 94 is flipped from the open position to the closed position, the locking pin 961 moves along the guide ramp 965 onto the support member 964 and is restrained between the locking buckle 962 and the support member 964. This prevents the locking pin from disengaging and strengthens the support for the cylinder cover.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the cylindrical cover 94 is hinged to the connecting bracket 93.

[0043] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application.
