DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a PETG film production mixing device, comprising a mixing barrel 12, the two ends of the mixing barrel 12 are respectively rotatably connected with a first end cap 3 and a second end cap 13, such as Figure 3 As shown, annular grooves 19 are coaxially provided at both ends of the mixing barrel 12, and annular holders 18 are provided at the ends of the first end cover 3 and the second end cover 13 close to the mixing barrel 12, which are matched with the annular grooves 19. Specifically, a bearing is provided on the annular holder 18, and the bearing is placed in the annular grooves 19, thereby ensuring that the mixing barrel 12 can rotate stably between the first end cover 3 and the second end cover 13, and can improve the sealing of the connection.

[0021] At the same time, in order to ensure the stable placement of the device, Figure 1 , 2 As shown, the first end cover 3 and the second end cover 13 are fixed by symmetrically arranged U-shaped connecting seats 5, so that a stable frame structure is formed between the first end cover 3, the second end cover 13 and the two U-shaped connecting seats 5, so that the mixing barrel 12 located therein can achieve stable rotation.

[0022] like Figure 1 , 2 As shown, a feed hopper 1 for facilitating the transportation of raw materials is connected to the outer wall of the first end cover 3. In actual use, a sealing cover is hinged on the top of the feed hopper 1 to prevent the internal raw materials from falling from the feed hopper 1. At the same time, a discharge pipe 15 for facilitating the discharge of materials is fixedly connected to the outer wall of the second end cover 13. At the same time, in order to control the stable discharge of materials, a valve is fixedly connected to the discharge pipe 15. The valve is a solenoid valve. In actual use, a control switch is fixedly connected to the second end cover 13 or the first end cover 3, and the solenoid valve is connected to the control switch.

[0023] like Figure 1 , 2As shown in the figure, in order to achieve the stable rotation of the mixing drum 12, a second motor 10 is fixedly connected to the top of the first end cover 3 through a motor base 6. A fixed frame 8 with a U-shaped structure is fixedly connected to the top of the second motor 10. A gear 9 is coaxially connected to the output end of the second motor 10, and the end of the output end of the second motor 10 is rotatably connected to the side wall of the fixed frame 8, realizing the stable rotation of the gear 9. A number of teeth 7 are circumferentially connected to the outer wall of the mixing drum 12, and the gear 9 is meshed with the teeth 7. The second motor 10 drives the gear 9 to rotate, and then the mixing drum 12 can be driven to rotate and mix materials through the cooperation of the gear 9 and the teeth 7.

[0024] As Figure 3 shown in the figure, in order to improve the mixing efficiency, a rotating shaft 14 is rotatably connected between the first end cover 3 and the second end cover 13, and a spiral blade 21 is fixedly connected to the rotating shaft 14. One end of the rotating shaft 14 is coaxially connected to a first motor 2, and the first motor 2 is fastened to the outer wall of the first end cover 3. The first motor 2 drives the spiral blade 21 to rotate, which can drive the raw materials inside to rotate. At the same time, in actual use, by setting the rotation directions of the first motor 2 and the second motor 10 in the opposite direction, efficient mixing can be achieved.

[0025] As Figure 3 shown in the figure, in order to ensure that the raw materials located on the inner wall of the mixing drum 12 are also fully mixed, a spiral side plate 20 is fixedly connected to the inner wall of the mixing drum 12, and the spiral blade 21 is located inside the spiral side plate 20 and coaxially arranged with it, thereby avoiding the accumulation of raw materials on the inner wall of the mixing drum 12 and further improving the mixing efficiency.

[0026] As Figure 1 、 2 shown in the figure, support frames 11 are rotatably connected to the outer walls of the U-shaped connecting seats 5, and the support frames 11 are vertically connected to the top of the support base 4. An electric telescopic rod 17 is rotatably connected between the bottom of the first end cover 3 and the support base 4. Hinge seats 16 are fixedly connected to both the bottom of the first end cover 3 and the top of the support base 4, and the end of the electric telescopic rod 17 is rotatably connected to the hinge seat 16. This not only ensures the stable placement of the device, but also, when performing the feeding operation, by controlling the electric telescopic rod 17 to drive the first end cover 3 to rotate downward, the mixed raw materials in the mixing drum 12 can be easily accumulated inside the first end cover 3, and by controlling the solenoid valve to open, the raw materials can be discharged from the discharge pipe 15.

[0027] In summary, when the PETG film production mixing device is in use, the raw materials to be mixed are fed from the feed hopper 1 into the mixing cylinder 12. Under the simultaneous rotation of the mixing cylinder 12 and the spiral blade 21, the raw materials inside can be fully mixed. Moreover, the mixed raw materials can be quickly discharged through the electric telescopic rod 17 and the discharge pipe 15. It not only has a simple structure but also can improve the mixing efficiency of the raw materials and ensure the quality of film production.
