[0002] The existing film laminating method generally adopts manual loose piece laminating, and the positioning difference of loose piece materials is large. During the laminating process, the accuracy of material laminating is poor. Moreover, after the film laminating is completed, personnel need to manually flatten the film, which may easily cause dirt and damage to the product. For this reason, the utility model patent with publication number CN205905523U discloses a bottom film flattening mechanism, a bottom film flattening mechanism, which includes an adjustable cantilever; the adjustable cantilever is placed horizontally; an L-shaped cylinder fixing frame is arranged at the end of the adjustable cantilever; one end of the cylinder fixing frame is horizontally fixed to the bottom side of the adjustable cantilever, and the other end is perpendicular to the adjustable cantilever and fixed with a downward pressure cylinder on the outer surface; the ends of the two piston rods of the downward pressure cylinder are fixed with connecting fixing blocks; the bottom side of the connecting fixing block is fixed with a long strip of foam pressing block. The utility model provides a bottom film flattening mechanism, which drives a foam pressing block to repeatedly perform a downward pressing action through a downward pressing cylinder, and can flatten the bottom film in stages. The action is fast, and no secondary damage is caused to the bottom film. The utility model is easy to use, has a high downward pressing efficiency, and has a good flattening effect. However, in specific use, the above-mentioned foam pressing block needs to be cleaned when it is not used for a long time. In the existing method, in the above-mentioned structure, the cleaning of the foam pressing block must be carried out under the entire mechanism, which is inconvenient for the staff to operate, so how to solve this problem needs to be considered.

DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] Reference Figure 1-Figure 3A bottom film flattening mechanism includes a connecting block 1 and a U-shaped plate 4. The lower end of the connecting block 1 is symmetrically fixedly connected to two hydraulic telescopic rods 2. Both of the two hydraulic telescopic rods 2 are multi-section telescopic rods. The telescopic rod ends of the two hydraulic telescopic rods 2 are commonly fixedly connected to a rectangular block 3. The upper end of the U-shaped plate 4 is fixedly connected to a limiting block 6. It also includes a flattening mechanism. The flattening mechanism includes a foam pressing block 5 provided on the inner side of the U-shaped plate 4. The foam pressing block 5 is connected to the U-shaped plate 4 by a plurality of limiting screws 7. It also includes a limiting mechanism. The limiting mechanism is used to limit the rectangular block 3 and the limiting block 6. The limiting mechanism includes a rectangular groove 15 provided at the lower end of the rectangular block 3. The upper end of the limiting block 6 extends to the rectangular groove. 15, slide grooves 9 are provided on the inner walls on the left and right sides of the rectangular groove 15, and the two slide grooves 9 are provided with inserting strips 11 that can slide left and right, and the opposite sides of the two inserting strips 11 are extended into the slot 8, and the opposite sides of the two inserting strips 11 are elastically connected to the inner walls of the corresponding slide grooves 9 through springs 10, and the opposite sides of the two inserting strips 11 are rotatably connected with rotating columns 14, and the opposite sides of the two inserting strips 11 are elastically connected to the inner walls of the corresponding slide grooves 9 through springs 10, and the other ends of the two rotating columns 14 extend to the outside and are fixedly connected to the abutment plate 13, and the left and right sides of the rectangular block 3 are fixedly connected with rectangular strips 12, and the two rectangular strips 12 are respectively matched with the corresponding abutment plates 13.

[0015] When in use, if the foam pressing block 5 needs to be cleaned, it is only necessary to pull the push plate 13 to move, so that the corresponding insertion strip 11 can be left from the corresponding slot 8 by using the rotating column 14, and then the rotating column 14 is rotated so that the right side of the push plate 13 contacts the rectangular strip 12. At this time, the push plate 13 cannot move to the right, and the spring 10 is in a stretched state. Similarly, the other side also performs synchronous operation. Under the action of gravity, the limit block 6, the U-shaped plate 4 and the foam pressing block 5 will fall. At this time, the whole can be taken to the cleaning place for cleaning, which is convenient for the cleaning operation. Subsequently, the limit block 6 is reinserted into the rectangular groove 15, and then the two push plates 13 are rotated to restore the original state. At this time, under the elastic action of the spring 10, the two insertion strips 11 are inserted into the slot 8 again to complete the limiting. If the foam pressing block 5 needs to be replaced, it is only necessary to remove the multiple limit screws 7, and then replace the new foam pressing block 5, and limit it by the limit screws 7.
