[0021] In order to make the purpose and technical scheme of the utility model embodiment more clear, the following will be combined with the drawings of the utility model embodiment, and the technical scheme of the utility model embodiment is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0022] Figure 1 This is a schematic diagram of the film-cutting mechanism in this utility model. Figure 1 As shown, the film cutting mechanism 1 is an important component of the laminating machine, used to cut the waste film at the edge of the product on the mold after lamination. Figure 2 for Figure 1 The exploded view, combined with Figure 1 and Figure 2 It is known that the worktable 11 of the film cutting mechanism 1 has a mounting hole 111 at its center, and a fixing plate 12 is installed in the mounting hole 111. The fixing plate 12 has a first through hole 121 at its center, and at least one movable groove 122 is formed outward from the edge of the first through hole 121. A second through hole 123 is formed on the edge of each movable groove 122, and the second through holes 123 are formed around the first through hole 121. The shape and size of the first through hole 121 are based on the mold design, while the shape and size of the movable groove 122 are based on the tool design.

[0023] The first through hole 121 is used to house the carrier assembly 131, which passes through the fixing plate 12 and is clearance-fitted with the fixing plate 12. The carrier assembly 13 includes a mold 131 and a lifting rod 132, with the lifting rod 132 fixedly connected to the bottom of the mold 131. The mold 131 includes an inner cavity 1311 and a stretching portion 1312. The inner cavity 1311 is formed inside the mold 131, and the stretching portion 1312 extends outward from the upper edge of the inner cavity 1311. The inner cavity 1311 is accommodated within the first through hole 121. The mold 131 is used to support the paper-plastic product, and the upper surfaces of the inner cavity 1311 and the stretching portion 1312 are in direct contact with the paper-plastic product. The upper surface and inner surface of the mold 131 are provided with anti-slip textures to increase the friction and load stability between the mold 131 and the paper-plastic product, preventing the paper-plastic product from sliding during the lamination process. The bottom of the mold 131 is fixedly connected to one end of the lifting rod 132. By adjusting the extension and retraction of the lifting rod 132, the mold 131 can be axially displaced. The other end of the lifting rod 132 can be connected to the ground or other equipment.

[0024] Furthermore, a cutting assembly 14 is installed within the second through hole 123 and the movable groove 122. The cutting assembly 14 includes a blade 141, a first connecting block 142, a second connecting block 143, and a push rod 144. The blade 141 is vertically fixedly mounted on the first connecting block 142, and the second connecting block 143 is horizontally fixedly connected to the first connecting block 142 and the push rod 144. The blade 141 is designed according to the shape and size of the edge of the paper-plastic product, and the cutting edge of the blade 141 is aligned with the upper end face of the stretching part 1312 to ensure that the blade 141 accurately cuts the excess film on the side of the paper-plastic product. The first connecting block 142 is in direct contact with and matches the shape of the movable groove 122, which provides radially movable space for the first connecting block 142. Figure 3 for Figure 1 The sectional view, combined with Figures 1 to 3 It is known that the cutting tool 141 is fixedly mounted on the first connecting block 142, and the cutting edge of the cutting tool 141 extends out of the first connecting block 142. The upper end of the second connecting block 143 is fixedly connected to the first connecting block 142, and the upper end face of the second connecting block 143 is flush with the upper end face of the first connecting block 142. The second connecting block 143 passes through the second through hole 123, and the lower end of the second connecting block 143 is connected to the horizontally placed push rod 144. The push rod 144 is installed inside the worktable 11, and both ends of the push rod 144 are fixedly connected to the inner wall of the worktable 11 and the second connecting block 143, respectively. The second through hole 123 provides the second connecting block 143 with a horizontally movable space. Adjusting the extension of the push rod 144 can cause the second connecting block 143 to produce radial displacement, thereby driving the first connecting block 142 and the cutting tool 141 to move and cut the waste film. The push rod 144 and the lifting rod 132 are both connected to the control console (see... Figure 4 Electrical connection.

[0025] like Figure 4 As shown, the laminating machine includes a film cutting mechanism 1, a laminating fixture 2, a control console 3, a robotic arm 4, and at least one roller 5. The laminating fixture 2 is mounted above the film cutting mechanism 1, and the rollers 5 are provided on both sides of the laminating fixture 2. The control console 3 is electrically connected to the laminating fixture 2, the rollers 5, the film cutting mechanism 1, and the robotic arm 4. Figure 3 and Figure 4As shown, during operation of the film laminating machine, the paper-plastic product can be placed in the mold 131 by the mechanical arm 4, and the lifting rod 132 is adjusted to lift the mold 131 to a certain distance above the upper end surface of the fixed plate 12 to expose the side edge of the paper-plastic product. The film heating temperature is set, and the film on the roller 5 is adsorbed on the surface of the paper-plastic product by the film laminating jig 2 and wrapped around the side edge of the paper-plastic product. After the film covers all the surfaces of the paper-plastic product exposed outside, the lifting rod 132 is adjusted to lower the upper end surface of the mold 131 to be flush with the cutting edge of the cutter 141. Since the paper-plastic product is placed in the mold 131, and the lower end surface of the protruding part of the edge of the paper-plastic product is in contact with the upper end surface of the mold 131, the cutting edge of the cutter 141 is also flush with the lower end surface of the protruding part of the edge of the paper-plastic product. The cutter 141 is driven by the push rod 144 to move towards the mold 131 and cut off the waste film at the bottom of the protruding part of the edge of the paper-plastic product.

[0026] In summary, the film cutting mechanism and the film laminating machine are disclosed, at least one cutting assembly 14 is arranged around the carrier assembly 13, the cutting edge of the cutter 141 is aligned with the upper end surface of the mold 131, and the push rod 144 is adjusted to cut off the waste film at the edge sealing part of the paper-plastic product. The film cutting mechanism 1 has the advantages of simple structure, convenient operation and accurate cutting. The film cutting mechanism 1 can avoid manual film removal or secondary processing, which not only simplifies the operation process, but also improves the processing efficiency of the film laminating machine, and is beneficial to improving the economic benefits of the production link.
