[0002] A mixer is a vital piece of industrial equipment, primarily used for mixing, kneading, and plasticizing polymer materials such as rubber and plastics. A mixer is used to mix raw rubber with compounding ingredients, and can also plasticize natural rubber. In the rubber industry, mixers uniformly blend raw rubber with various compounding ingredients (such as vulcanizers, accelerators, antioxidants, reinforcing fillers, and liquid softeners). In the plastics industry, mixers are used to fuse different plastic particles. In the chemical industry, mixers play a key role in evenly dispersing solids, liquids, and gases.

[0003] During the production of existing packaging films, a mixer is also required to mix the raw materials. However, most existing mixers directly put the raw materials and auxiliary materials into the mixer during use, and the auxiliary materials are not fully dispersed, resulting in the mixer taking a long time to mix the materials. This not only reduces the mixing efficiency of the mixer, but also increases energy consumption, reducing the applicability of the mixer during use. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5As shown, the packaging film three-layer co-extrusion high-efficiency mixing machine includes a mixing barrel 1, which is composed of a barrel body, mounting legs, a feed pipe and a discharge valve. Under this action, the mixing barrel 1 is convenient for mixing and discharging. A servo motor 2 is bolted to the top of the mixing barrel 1. The output shaft of the servo motor 2 is fixedly connected to a first gear 3. A second gear 4 is engaged with one side of the first gear 3. The bottom of the second gear 4 passes through the interior of the mixing barrel 1 and is rotatably connected to the inner wall of the penetration. The bottom of the second gear 4 is fixedly connected to a distributing plate 5. The bottom of the distributing plate 5 is fixedly connected to a mixing frame 6. Under this action, the second gear 4 can drive the distributing plate 5 to rotate under the cooperation of the servo motor 2 and the first gear 3, thereby rotating the mixing frame 6 through the cooperation of the distributing plate 5. With the cooperation of the mixing rack 6, the raw materials inside the mixing barrel 1 are mixed to make the raw materials more uniform. The mixing rack 6 is composed of a vertical rod and several horizontal rods, and is used in conjunction with the mixing barrel 1. Under this function, the mixing efficiency of the materials inside the mixing barrel 1 can be further improved through the action of the mixing rack 6. A distributor 7 is provided on the top of the mixing barrel 1. The bottom of the distributor 7 penetrates into the interior of the mixing barrel 1 and is fixedly connected to the inner wall of the penetration. The top of the distributor 7 is connected to the storage hopper 8. Under this function, the staff can place the auxiliary materials that need to be put in inside the storage hopper 8, and under the action of the auxiliary materials' own weight, they can be discharged into the interior of the mixing barrel 1 through the distributor 7. When the second gear 4 rotates, it will drive the distributor plate 5 to rotate, and When the material distribution plate 5 rotates, the auxiliary material will be broken up and discharged into the interior of the mixing barrel 1, so that the auxiliary material can be more evenly distributed when added to the interior of the mixing barrel 1, effectively facilitating the subsequent mixing efficiency of the material by the mixer, and improving the applicability of the mixer. The top of the material distribution plate 5 is designed as an inclined structure, and the top of the material distribution plate 5 is fixedly connected to a baffle plate 16. Under this action, after the auxiliary material is discharged to the surface of the material distribution plate 5 through the distributor 7, the baffle plate 16 can assist in breaking up the auxiliary material with the cooperation of the baffle plate 16, and it can also make the auxiliary material discharge distance farther, effectively improving the discharge effect of the material distribution plate 5 on the auxiliary material, and further improving the use efficiency of the mixer. Connecting grooves 10 are provided on both sides of the inner cavity of the storage hopper 8, and a shaking mechanism is installed inside the connecting groove 10. 9. The other side of the second gear 4 is meshed with a driven gear 11. The top of the driven gear 11 is fixedly connected to a fixed rod 12. The upper surface of the fixed rod 12 is fixedly connected to a cam 13. The cam 13 cooperates with the rocking mechanism 9. Under this action, the driven gear 11 can be driven by the second gear 4 to drive the cam 13 to push the rocking mechanism 9 through the fixed rod 12, thereby reducing the blockage of the auxiliary material inside the storage hopper 8 and effectively improving the disturbance of the auxiliary material inside the storage hopper 8. The surface of the fixed rod 12 is rotatably connected to a support seat 14. One side of the support seat 14 is fixedly connected to the surface of the storage hopper 8. Under this action, the fixed rod 12 can be supported by the support seat 14, so that the fixed rod 12 can be more stable when rotating.To prevent the fixed rod 12 from being unstable during rotation and affecting the coordination between the cam 13 and the rocking mechanism 9, two support legs 15 are fixedly connected to both sides of the storage hopper 8. The other end of the support leg 15 is fixedly connected to the top of the mixing barrel 1. Under this function, the support legs 15 can support the storage hopper 8, making the storage hopper 8 more stable during use, and preventing the storage hopper 8 from easily shifting and affecting the coordination between the rocking mechanism 9 and the cam 13.

[0023] The rocking mechanism 9 includes a fixed plate 91 that slides on the inner wall of the connecting groove 10. A tension spring 92 is fixedly connected to the surface of one side of the fixed plate 91. The other end of the tension spring 92 is fixedly connected to the inner wall of the connecting groove 10. Two places on one side of the fixed plate 91 are fixedly connected to connecting plates 93. The surface of the connecting plate 93 is slidably connected to the surface of the cam 13. Under this action, the fixed plate 91 can be easily returned to its original position after the fixed plate 91 moves, so that after the cam 13 drives the fixed plate 91 to move through the connecting plate 93, under the action of the tension spring 92, when the cam 13 does not squeeze the connecting plate 93, the tension spring 92 can drive the connecting plate 93 to return to its original position, so that the connecting plate 93 moves back and forth to disturb the auxiliary material inside the storage hopper 8, thereby reducing the blockage of the auxiliary material inside the storage hopper 8.

[0024] It is worth noting that the technical features such as the mixing barrel 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, the staff discharges the raw materials into the interior of the mixing barrel 1 through the feeding pipe on the surface of the mixing barrel 1. When it is necessary to add auxiliary materials to the interior of the mixing barrel 1, the staff pours the auxiliary materials into the interior of the storage hopper 8. Under the influence of gravity, the auxiliary materials will be discharged into the interior of the mixing barrel 1 through the distributor 7. Then the staff turns on the servo motor 2. Under the action of the servo motor 2, the first gear 3 and the second gear 4 drive the distribution plate 5 to rotate. Under the cooperation of the distribution plate 5 and the baffle plate 16, the auxiliary materials can be broken up and thrown out, so that the auxiliary materials can be evenly distributed. The raw materials and auxiliary materials are mixed into the mixing barrel 1, and the mixing frame 6 can mix the raw materials and auxiliary materials, which effectively improves the mixing efficiency of the materials. When the second gear 4 rotates, the fixed rod 12 drives the cam 13 to rotate under the action of the driven gear 11, so that the cam 13 squeezes the surface of the connecting plate 93, thereby disturbing the material inside the storage hopper 8 under the action of the fixed plate 91 and the connecting plate 93, and the connection plate 93 can be reciprocated by the cooperation of the tension spring 92 and the cam 13, thereby reducing the blockage inside the storage hopper 8.
