[0030] In this embodiment, when in use, the container to be sealed is placed on the support table 28, and the moving cylinder 29 is started to drive the support table 28 to move, and the container is moved to the bottom of the film pressing mechanism, and the driving motor 11 is started at the same time. The driving motor 11 drives the driving roller 12 to rotate, and drives the film to move through the transmission roller 14. The film drives the feed roller 13 to rotate when moving, and the deceleration spring 17 is in a compressed state. The elastic force of the deceleration spring 17 causes the deceleration plate 18 to move toward the side of the electromagnet 19. The friction between the electromagnet 19 and the deceleration plate 18 decelerates the rotation of the feed roller 13, thereby preventing the feed roller 13 from rotating too fast, causing the film to loosen and affecting the film quality.

[0031] See also Figure 2-3 As an implementation method of the safety cover body 4: a fixing groove 20 is provided on the fixing rod 5, a fixing column 21 is provided in the fixing groove 20 of the limiting plate 7, sliding grooves 22 are provided on both sides of the fixing groove 20, sliding blocks 23 are provided on both sides of the fixing column 21, a fixing spring 24 is provided between the fixing column 21 and the fixing groove 20, and a fixing handle 25 is provided on the safety cover body 4.

[0032] More specifically, when moving the safety cover body 4, the limit plate 7 is moved outward, and the limit plate 7 drives the limit rod 8 to disengage from the limit hole 9. At the same time, the limit plate 7 drives the fixed column 21 to move outward in the fixed groove 20, and stretches the fixed spring 24. The sliding block 23 moves in the sliding groove 22 to limit the moving direction of the fixed column 21. The safety cover body 4 is flipped over by the fixed handle 25, so that the fixed rod 5 moves in the arc groove 6. After the movement is completed, the limit plate 7 is released. The limit plate 7 moves toward the side of the fixed rod 5 under the elastic force of the fixed spring 24, and then the limit plate 7 drives the limit rod 8 to be inserted into the limit hole 9, thereby fixing the position of the safety cover body 4 and protecting the staff through the safety cover body 4.

[0033] In summary, when the overall equipment is in use or running: when in use, place the container to be sealed on the support table 28, start the moving cylinder 29 to drive the support table 28 to move, move the container to the bottom of the film pressing mechanism, and start the drive motor 11 at the same time. The drive motor 11 drives the drive roller 12 to rotate, and drives the film to move through the transmission roller 14. The film drives the feed roller 13 to rotate when moving, and the deceleration spring 17 is in a compressed state. The elastic force of the deceleration spring 17 causes the deceleration plate 18 to move toward the side of the electromagnet 19. Through the friction between the electromagnet 19 and the deceleration plate 18, the rotation of the feed roller 13 is decelerated, thereby preventing the feed roller 13 from rotating too fast, causing the film to loosen and affecting the film quality.

[0034] When moving the safety cover body 4, the limit plate 7 is moved outward, and the limit plate 7 drives the limit rod 8 to disengage from the limit hole 9. At the same time, the limit plate 7 drives the fixed column 21 to move outward in the fixed groove 20, and stretches the fixed spring 24. The sliding block 23 moves in the sliding groove 22 to limit the moving direction of the fixed column 21. The safety cover body 4 is flipped over by the fixed handle 25, so that the fixed rod 5 moves in the arc groove 6. After the movement is completed, the limit plate 7 is released. The limit plate 7 moves to the side of the fixed rod 5 under the elastic force of the fixed spring 24, and then the limit plate 7 drives the limit rod 8 to be inserted into the limit hole 9, so as to fix the position of the safety cover body 4 and protect the staff through the safety cover body 4.
