[0036] The second liner 31 is symmetrically mounted with a horizontal shaft 35 on the lower side of the opposite side. A pressure roller 36 is fixedly mounted in the middle of the horizontal shaft 35 and the pressure roller 36 is located on both sides of the film cutting blade 34. A servo motor 37 is fixedly connected to the end of the horizontal shaft 35 near the film supply assembly 2. The servo motor 37 is fixedly mounted on the side wall of the second liner 31.

[0037] The paper drum fixing assembly 5 includes an installation groove 51. The support plates 1 on both sides of the rectangular through groove 4 are symmetrically provided with installation grooves 51. A rotating disk 52 is rotatably installed in the installation groove 51. An annular sliding groove 53 is provided on the side wall of the rotating disk 52. A limiting rod 54 is fixedly installed on the side wall of the installation groove 51. The end of the limiting rod 54 is slidably installed in the annular sliding groove 53 and plays a limiting role for the rotating disk 52.

[0041] The pressure block 8 is made of foam material, and its lower end face has an upward concave arc-shaped structure in the middle, and the edges of the pressure block 8 are treated with arc-shaped chamfers.

[0042] Working principle:

[0043] The film roller 23 is sleeved on the film shaft 22. The film is drawn out from the film roller 23, passes under the guide roller 25 for guidance, and then passes under the pressure roller 36 to the vicinity of the paper drum fixing assembly 5, in preparation for subsequent film coating and film cutting.

[0044] First, manually move the frustum-shaped clamping blocks 58 to both sides to separate them, compressing the spiral spring 59. Then, place the paper drum in the rectangular through slot 4. The reaction force of the spiral spring 59 will cause the frustum-shaped clamping blocks 58 on both sides to move closer to each other, finally fixing the paper drum. At this time, the linkage rod 581 will be inserted into the insertion hole 582.

[0045] The film end is attached to the upper surface of the paper drum. At the same time, the electric push rod 7 is activated, which drives the film pressing block 8 to move downward and press the film end onto the upper surface of the paper drum. The drive motor 553 is activated, which drives the transmission gear 552 to rotate. Under the action of the reduction gear 551, the rotating shaft 55 drives the rotating disk 52, the rectangular frame 56, the "T" shaped rod 57, the frustum-shaped pressing block 58, and the paper drum after it is supported to rotate. The film covers the surface of the paper drum during the rotation of the paper drum. The film pressing block 8 is made of foam material. Its lower end face has an upward concave arc structure and the edges are rounded and chamfered, which can better fit the surface of the paper drum and press the film onto the paper drum to realize the film coating operation.

[0046] When the paper drum is about to be coated, the electric slider 33 is activated, which drives the film cutting blade 34 to move. With the cooperation of the pressure roller 36, the film is cut. The cut film continues to move towards the paper drum until the coating is completed. At this time, the coated paper drum is removed manually and the new paper drum is fixed in the rectangular through slot 4. At the same time, the servo motor 37 works and drives the horizontal shaft 35 near the film supply assembly 2 to rotate. The pressure roller 36 in the middle of the horizontal shaft 35 rotates accordingly, thereby conveying the subsequent film to the right for the next coating operation.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
