[0018] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below, obviously, the described embodiment only is the embodiment of a part of the utility model, is not all the embodiment. Based on the embodiment in the utility model, all other embodiments that the person skilled in the art obtains without making the creative labor should belong to the scope of the protection of the utility model.

[0019] As shown in the accompanying Figures 1-3 Drawings.

[0020] A film stretching device for a film coating machine includes a base frame 1. A placement seat 11 for placing goods is provided in the middle of the base frame 1. A hydraulic cylinder 2 is provided on each side of the base frame 1. The telescopic rod of the hydraulic cylinder 2 is connected to the top frame 21 above. Multiple mounting brackets 3 are provided on the outside of the base frame 1. A lifting groove 31 for mounting a movable plate 4 is opened in the mounting bracket 3. A pull plate 5 is installed at the end of the movable plate 4 facing the placement seat 11. A movable plate 6 is installed above the movable plate 4. A T-shaped sliding groove 61 is opened in the movable plate 6. A pull rod 9 is installed in the top frame 21 and directly above the movable plate 6. The lower end of the pull rod 9 is provided with a hanging sleeve 91 that is embedded in the sliding groove 61 in the movable plate 6. Based on the above structure, when the hydraulic cylinder 2 extends and pushes the top frame 21 to lift, the movable plate 6, the movable plate 4, and the pull plate 5 can be driven to rise under the action of the pull rod 9 and the hanging sleeve 91.

[0021] A lifting plate 7 is placed above the movable plate 6. Movable slots 32 for limiting the stable lifting of the lifting plate 7 are provided on both sides of the mounting frame 3. A motor 8 is installed above one end of the lifting plate 7. A gear 81 is connected to one side of the motor 8 and above the movable plate 6. A toothed groove 62 that meshes with the gear 81 is provided on one side of the movable plate 6. Based on this structure, when the motor 8 rotates, the movable plate 6, the movable plate 4, and the pull plate 5 can move in the horizontal direction through the meshing of the gear 81 and the toothed groove 62.

[0022] The procedure for using this device is as follows: (see attached) Figure 1 As shown, the goods requiring film covering are placed above the placement seat 11. Then, the extension of the hydraulic cylinder 2 raises the movable plate 6, the moving plate 4, and the pull plate 5 to a position higher than the goods. The film is then placed over the pull plates 5 in the multiple mounting frames 3. At this time, by starting the motor 8 in each mounting frame 3, the moving plate 4 moves in the opposite direction to the placement seat 11, thus stretching the film. At this time, the hydraulic cylinder 2 retracts, causing the movable plate 6, the moving plate 4, and the pull plate 5 to descend synchronously, thus covering the surface of the goods with the stretched film. Since the height of the pull plate 5 is lower than the placement seat 11, the film covering is completed when the moving plate 4 descends to contact the base frame 1, and the film-covered goods can then be taken out.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
