[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] See Figures 1-3 A rubber powder mixing device for processing waste tires into recycled rubber includes a mixing tank 1, which is mainly used to hold the rubber powder that needs to be mixed.

[0032] The stirring assembly 2 and the stirring drive assembly 7.

[0033] The stirring assembly 2 is installed inside the stirring tank 1. The stirring assembly 2 is mainly used to stir rubber powder or rubber granules. The stirring drive assembly 7 is installed at the other end of the first rotating column 4. The stirring drive assembly 7 is mainly used to drive the stirring assembly 2.

[0034] The stirring assembly 2 includes a first fixed rod 3, a first rotating column 4 perpendicular to the bottom of the stirring tank 1, several stirring rods 5, and stirring blades 6, which are twice the number of stirring rods 5.

[0035] The first fixed rod 3 is welded to the top of the mixing tank 1. One end of the first rotating column 4 is rotatably mounted on the first fixed rod 3, and the other end of the first rotating column 4 is rotatably mounted at the bottom of the mixing tank 1. The first rotating column 4 passes through the bottom of the mixing tank 1. Each stirring rod 5 is welded to the outer wall of the first rotating column 4. In this embodiment, twelve stirring rods 5 are preferably provided, and the length of each stirring rod 5 is equal to the radius of the mixing tank 1. The stirring rods 5 are mainly used to stir and mix the rubber granules. Each stirring blade 6 is welded to the first rotating column 4. Since the number of stirring blades 6 is twice the number of stirring rods 5, twenty-four stirring blades 6 are preferably provided in this embodiment. The stirring blades 6 are staggered with the stirring rods 5, and the length of the stirring blades 6 is equal to the radius of the mixing tank 1. Since the stirring rods 5 and stirring blades 6 are fixed on the first rotating rod, when the first rotating column 4 is rotated, the first rotating column 4 rotates, driving the stirring blades 6 and stirring rods 5 to rotate, so that the stirring rods 5 mix the rubber granules, and the stirring blades 6 crush large pieces of rubber, so that the rubber granules are mixed more thoroughly.

[0036] First, refer to Figures 4-5 In this embodiment, a heating resistance wire 8 is also included. The heating resistance wire 8 is installed on the outer wall of the mixing tank 1. The heating resistance wire 8 is mainly used to heat the rubber granule powder, making the raw materials easier to mix. A fixing ring 9 is welded to the top of the mixing tank 1. The diameter of the fixing ring 9 is the same as the diameter of the mixing tank 1. A protective barrel 10 is welded to the bottom of the fixing ring 9. The fixing ring 9 is mainly used to fix the protective barrel 10 and provide an installation platform for the protective barrel 10. The protective barrel 10 is mainly used to protect the heating resistance wire 8 and prevent workers from being burned due to overheating of the device.

[0037] Then, refer to Figure 6 In this embodiment, the stirring drive assembly 7 includes a first motor 11, which is installed at the bottom of the protective tank 10. A first gear 12 is fixed to the output shaft of the first motor 11 by a key. Since the first gear 12 is fixed to the output shaft of the first motor 11, the rotation of the first motor 11 drives the first gear 12 to rotate. The other end of the first rotating column 4 is fixed to a second gear 13 by a key, and the second gear 13 meshes with the first gear 12. The first motor 11 drives the first gear 12 to rotate, and the rotation of the first gear 12 drives the second gear 13 to rotate.

[0038] Secondly, see Figures 7-8In this embodiment, a sealing drive assembly 14 is also included. The sealing drive assembly 14 is installed on the outer wall of the protective barrel 10 and is mainly used to control the opening and closing of the iris valve 19. The sealing drive assembly 14 includes a first fixing plate 15, which is welded to the outer wall of the protective barrel 10. A second motor 16 is installed on the first fixing plate 15 by screws. The first fixing plate 15 is mainly used to fix the second motor 16 and provide an installation platform for the second motor 16. A third gear 17 is fixed on the output shaft of the second motor 16 by a key. The third gear 17 is fixed on the output shaft of the second motor 16. When the second motor 16 rotates, the second motor 16 drives the third gear 17 to rotate. A fourth gear 18 is rotatably arranged on the fixing ring 9. The fourth gear 18 meshes with the third gear 17. The rotation of the third gear 17 drives the fourth gear 18, which meshes with the third gear 17, to rotate.

[0039] It also includes an iris valve 19, the bottom of which is fixedly installed on the top of the fourth gear 18. The iris valve 19 is mainly used to control the feed port of the device. When feeding, the iris valve 19 is opened to allow the raw material to enter the mixing tank 1. When mixing, the iris valve 19 is closed to prevent the raw material from splashing out and being wasted.

[0040] See again Figure 9 In this embodiment, a collection frame 20 is also included. The collection frame 20 is welded to the top of the iris valve 19. The collection frame 20 is mainly used to facilitate the workers to pour the raw materials into the mixing tank 1 and prevent the waste of raw materials when pouring.

[0041] Finally, see Figures 10-12 In this embodiment, a collection valve 21 is also included. The collection valve 21 is installed at the bottom of the mixing tank 1. The collection valve 21 is a solenoid valve. By controlling the opening and closing of the solenoid valve, the mixed raw materials are discharged. A cut 22 is provided on the protective tank 10. A collection basket 23 is slidably arranged inside the cut 22. The cut 22 is mainly used to provide an installation position for the collection basket 23. The collection basket 23 is mainly used to collect the mixed raw materials discharged by the solenoid valve. The shape of the collection basket 23 is adapted to the shape of the cut 22. A handle 24 is welded on the collection basket 23. The handle 24 is mainly used to assist the operator in sliding the collection basket 23, making it convenient for the operator to collect the mixed raw materials.

[0042] Working principle:

[0043] The rubber powder mixing device for processing waste tires into recycled rubber is used as follows: First, the device is placed in the desired location. Then, the worker pours the raw materials into the mixing tank 1 through the collection frame 20. The heating resistance wire 8 is then activated, heating the mixing tank 1, which in turn heats the raw materials. Once the appropriate temperature is reached, the second motor 16 is activated. The second motor 16 drives the third gear 17, which in turn drives the fourth gear 18, which meshes with the third gear 17. The fourth gear 18 then closes the iris valve 19 to prevent material from splashing out during mixing and causing waste. The first motor 11 rotates, driving the first gear 12 to rotate. Because the first gear 12 meshes with the second gear 13, the rotation of the first gear 12 drives the rotation of the second gear 13, which in turn drives the first rotating rod to rotate. Since the stirring rod 5 and the stirring blade 6 are fixed on the first rotating rod, when the first rotating rod rotates, it drives the stirring blade 6 and the stirring rod 5 to rotate, causing the stirring rod 5 to mix the rubber granules and powder, and the stirring blade 6 to crush large pieces of rubber. Then, the solenoid valve is activated to open and discharge the mixed raw materials. After the discharge is complete, the worker pulls the handle 24 to remove the collection basket 23 and collect the mixed raw materials.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
