[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-6 A multi-color film production device includes a work platform 1 and a casting machine 2. A plurality of shells 3 are provided on the surface of the work platform 1 corresponding to the casting machine 2. A mixing worm 4 and a hot air pipeline 5 are provided in the shell 3. A melt mixing tube 6 is provided at one end of the shell 3. The output end of the melt mixing tube 6 is fixedly connected to the input end of the casting machine 2. A mounting seat 7 is provided at the other end of the shell 3. A stirring barrel 8 is provided on the top of the shell 3. A plurality of feed ports 9 are opened on the top of the stirring barrel 8. A stirring assembly is provided in the stirring barrel 8.

[0026] A plurality of sleeves 10 are provided on one side of the mounting base 7 corresponding to the housing 3 , and a hybrid motor 11 is provided on the other side of the mounting base 7 .

[0027] It should be noted that the sheet casting machine 2 is the starting end of the tape casting production line, and the tape casting production line is a prior art.

[0028] Furthermore, a mixing chamber 12 is provided in the shell 3, and a heating chamber 13 for heating raw materials is provided between the shell 3 and the mixing chamber 12. Pipe grooves 14 matching the hot air pipeline 5 are provided at the four corners of the heating chamber 13. An extrusion port 15 matching the input end of the melt mixing tube 6 is provided at the output end of the shell 3, and the extrusion port 15 is fixedly connected to the input end of the melt mixing tube 6.

[0029] Furthermore, the mixing worm 4 is located in the mixing chamber 12, one end of the mixing worm 4 is set to be conical, and the other end of the mixing worm 4 is fixedly connected to the rotating shaft 16, the center of the rotating shaft 16 is fixedly connected to the driving rod 17, the rotating shaft 16 is rotatably connected to the mounting seat 7, and the driving rod 17 passes through the mounting seat 7 and is rotatably connected to the driving mixing motor 11.

[0030] Furthermore, the hot air pipeline 5 includes a connecting pipe 18, the hot air pipeline 5 is located in the heating chamber 13 and is flange-connected to each other through the connecting pipe 18, a special-shaped coil 19 is provided at the input end of the hot air pipeline 5 corresponding to the shell 3, the input end of the hot air pipeline 5 is connected to the hot air delivery pipe 20 through the sleeve 10, and the output end of the hot air pipeline 5 is connected to the hot air recovery pipe 21 through the sleeve 10.

[0031] A further advantage of adopting the above method is that, when in use, multiple mixing chambers 12 can be heated simultaneously by a single hot air blower, and the hot air can be discharged from the hot air recovery pipe 21 to the heat recovery device, thereby saving energy. By arranging the special-shaped coil 19 to avoid the output end of the mixing barrel 8, the shell 3 does not need to be provided with an unnecessary extension part to connect to the mixing barrel 8, thereby saving space.

[0032] Furthermore, a mounting ring 22 is fixedly connected to the intersection inside the melt mixing tube 6 , and a spiral blade 23 is fixedly connected to the inner wall of the mounting ring 22 .

[0033] A further advantage of adopting the above method is that the monochrome melt enters the melt mixing tube 6 from the extrusion port 15 after being rotated, extruded and pushed by the mixing worm 4. During the transportation process, the monochrome melt will converge at the intersection of the melt mixing tube 6. The merged multi-color melt is insufficiently stirred by the spiral blades 23 and then output to the casting machine 2, and a film with disordered color marks is made by the casting machine 2.

[0034] Furthermore, the stirring assembly includes a stirring rod 24, the top end of which passes through the stirring barrel 8 and is rotatably connected to a stirring motor 25, and the bottom of the stirring rod 24 is fixedly connected to a feeding worm 26, which can evenly transport the masterbatch to the mixing chamber 12 while stirring the masterbatch.

[0035] When the utility model is in use, hot air is input into the hot air pipeline 5 through the hot air delivery pipe 20, and the mixing chamber 12 is preheated by the hot air pipeline 5. After the mixing chamber 12 reaches the working temperature, the industrial computer starts the mixing motor 11 and the stirring motor 25. The mixing motor 11 drives the mixing worm 4 to rotate in the mounting seat 7, and the stirring motor 25 drives the stirring rod 24 and the feeding worm 26 to rotate;

[0036] The raw materials required for the two colors are respectively input from the feed port 9, and the raw materials are stirred by the stirring rod 24 and evenly fall into the bottom of the stirring barrel 8, and are uniformly transported to the mixing chamber 12 by the feeding worm 26. Through the shearing of the mixing worm 4 and the heating of the hot air pipeline 5, uniform single-color melts are formed respectively. After the single-color melt is rotated, extruded and pushed by the mixing worm 4, it enters the melt mixing tube 6 from the extrusion port 15. During the transportation process, the single-color melt will converge at the intersection of the melt mixing tube 6, and the merged multi-color melt will be insufficiently stirred by the spiral blade 23. After the insufficiently stirred multi-color melt enters the casting machine 2, it is made into a membrane with disordered color marks by the casting machine 2. The membrane with disordered color marks is stretched by the cast production line to form a multi-color film with disordered color marks, thereby realizing the direct production of multi-color film. Since the multi-color film is integrally formed, it will not fade due to wear, thereby extending its service life.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
