The two sides of the stand are fixedly connected to positioning plates, and the outer side of the positioning plates is fixedly connected to mounting blocks. The mounting blocks are inserted into the inside of the connecting grooves.

[0010] As a further technical solution of this utility model, a fixing frame is fixedly connected to the front end of the left side of both the first connecting seat and the second connecting seat. A threaded rod is vertically arranged at the front end of the left side of the first connecting seat and the second connecting seat.

[0025] Please see Figure 1-4 A casting apparatus for preparing a high-barrier composite film includes a first connecting seat 8 and a second connecting seat 12. The second connecting seat 12 is arranged parallel to the first connecting seat 8 directly below it. A base 1 is fixedly connected to the left side of the first connecting seat 8 and the second connecting seat 12. The front end of the base 1 is provided with a component that is easy to disassemble and assemble.

[0026] The components that are easy to assemble and disassemble include a socket 17, a support frame 3 fixedly connected to the top and bottom of the front end of the base 1, a winding drum 2 parallel to the front end of the base 1, a movable rod 16 running through the inside of the winding drum 2, the top of the support frame 3 being concave inward in an arc shape, and a stand 15 fixedly connected to the bottom of the arc concavity, and positioning plates 18 fixedly connected to both sides of the stand 15, and two sets of sockets 17 being provided, which are respectively sleeved on the outer ends of the two sets of stand 15.

The top end of the movable rod 16 is fixedly connected to the first drive motor 4.

[0028] The socket 17 has inwardly recessed connecting grooves 22 on both sides of its inner end. The upright 15 has positioning plates 18 fixedly connected to both sides. The positioning plates 18 have mounting blocks 14 fixedly connected to the outer side of the positioning plates 18. The mounting blocks 14 are inserted into the inside of the connecting grooves 22.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, during use, both ends of the movable rod 16 are inserted into the interior of the corresponding upright 15, and the socket 17 is fitted onto the outer end of the upright 15. The two ends of the movable rod 16 are installed at the inner end of the socket 17, ensuring the movable connection between the two. This continues until the mounting block 14 is inserted and fixed inside the connecting groove 22, fixing the socket 17 in the current position. After the first drive motor 4 runs, it drives the winding drum 2 to rotate flexibly between the two sets of uprights 15 through the movable rod 16, winding up the high-barrier composite film.

[0030] The front ends of the left side of the first connecting seat 8 and the second connecting seat 12 are both fixedly connected to the fixing frame 19.

The auxiliary rotating shaft 6 cooperates with the active rotating shaft 10 to ensure that the raw material moves outward on the surface of the conveyor belt 11 for stable conveying. After the servo motor 5 runs, it drives the threaded rod 13 to rotate flexibly between the two sets of fixed frames 19. According to the thread direction on the surface of the threaded rod 13, the movable seat 26 installed on its outside moves flexibly. The scraper 20 separates the raw material from the high-barrier composite film. The two ends of the movable rod 16 are respectively inserted into the interior of the corresponding upright 15. The socket 17 is sleeved and installed on the outer end of the upright 15, and the two ends of the movable rod 16 are respectively installed on the inner end of the socket 17, ensuring the movable connection between the two until the mounting block 14 is inserted and fixed inside the connecting groove 22, fixing the socket 17 in the current position.
