Description

Technical Field

[0001] This utility model belongs to the field of internal mixer technology, specifically relating to a three-axis floor-standing tilting bucket energy-saving internal mixer. Background Technology

[0002] A closed-type rubber mixing mill, also known as an internal mixer, is mainly used for the plasticizing and mixing of rubber. An internal mixer is a machine equipped with a pair of stirring rods of a specific shape that rotate relative to each other, which intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure. Some internal mixers can flip the mixing chamber after the material is processed to facilitate the removal of the material.

[0003] When the existing internal mixer is working, the two stirring rods rotate relative to each other, clamping the material from the feed port and bringing it into the roller gap. The material is squeezed and sheared by the stirring rods, and after passing through the roller gap, it hits the sharp edge of the lower top bolt and is divided into two parts. They then return to the top of the roller gap along the gap between the front and rear chamber walls and the stirring rods. Although the amount of material produced in one mixing is several times that of an open mill, the rubber compound is prone to uneven dispersion and scrapping, wasting raw materials and having to be mixed again. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a three-axis floor-standing tilting bucket energy-saving internal mixer, which can make the rubber material more uniform.

The mixing chamber is rotatably mounted on the machine body, and the tilting assembly is mounted on the machine body and located on one side of the mixing chamber. The driving end of the tilting assembly is rotatably connected to the side wall of the mixing chamber. The first stirring rod, the second stirring rod, and the third stirring rod are arranged in parallel and rotatably inside the mixing chamber.

[0006] The machine body has a mixing motor on one side of the mixing chamber, and a gear transmission box is provided on the side of the mixing chamber facing the mixing motor. The gear transmission box is connected to the mixing motor in a driving connection, and the three stirring rods are respectively connected to the gear transmission box in a driving connection.

[0007] The gear transmission box is equipped with a first gear, a second gear, and a third gear.

The first gear and the second gear are meshed with each other. The third gear is connected to the second gear via a first transmission belt and is connected to the internal mixing motor.

[0008] The first and second stirring rods are each provided with two stirring blades, and the third stirring rod is provided with three stirring blades.

[0009] The gear transmission box is provided with a first drive wheel, a second drive wheel and a third drive wheel. The first drive wheel, the second drive wheel and the third drive wheel are coaxially connected to the first stirring rod, the second stirring rod and the third stirring rod respectively. The first drive wheel is provided with a first transmission belt that is connected to the second drive wheel.

[0016] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation. Example 1

[0017] like Figures 1-3 As shown, this embodiment provides a three-axis floor-standing tilting bucket energy-saving internal mixer, including a machine body 1, a mixing chamber 2, a tilting assembly 3, a first stirring rod 4, a second stirring rod 5, and a third stirring rod 6. The mixing chamber 2 is rotatably mounted on the machine body 1, and the tilting assembly 3 is mounted on the machine body 1 and located on one side of the mixing chamber 2. The drive end of the tilting assembly 3 is rotatably connected to the side wall of the mixing chamber 2. The first stirring rod 4, the second stirring rod 5, and the third stirring rod 6 are arranged side by side and rotated inside the mixing chamber 2. By setting three parallel stirring rods, the shear area during mixing is increased, making the mixing more uniform. Furthermore, the three stirring rods are arranged in a triangle. Regardless of the arrangement, the upper stirring rod will always obstruct the cleaning process, making it more difficult. However, the parallel stirring rods do not have the obstruction problem of the upper and lower stirring rods, making them easier to clean than the internal mixer with three stirring rods arranged in a triangle, and also increasing the uniformity of the mixing.

[0018] Furthermore, the machine body 1 has a mixing motor 7 on one side of the mixing chamber 2, and a gear transmission box 9 is provided on the side of the mixing chamber 2 facing the mixing motor 7. The gear transmission box 9 is connected to the mixing motor 7, and the three stirring rods are connected to the gear transmission box 9 respectively. The mixing motor 7, in conjunction with the gear transmission box 9, drives the three stirring rods to perform mixing and mixing.

[0019] Furthermore, the gear transmission box 9 is equipped with a first gear 10, a second gear 11, and a third gear 12. These gears are coaxially connected to the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6, respectively. The first gear 10 and the second gear 11 mesh with each other, and the third gear 12 is connected to the second gear 11 via a first transmission belt 13. The third gear 12 is also connected to the internal mixing motor 7. Specifically, the first stirring rod 4 and the second stirring rod 5 each have two stirring blades 14, and the third stirring rod 6 has three stirring blades 14. The meshing of the first gear 10 and the second gear 11 causes the first stirring rod 4 and the second stirring rod 5 to rotate in opposite directions for internal mixing, while the third stirring rod 6 rotates in the same direction as the second stirring rod 5, providing auxiliary mixing and ensuring uniform mixing. The three stirring blades 14 on the third stirring rod 6 increase the mixing area. Example 2

[0020] like Figures 4-5 As shown, the structural features differ from other embodiments in that: the gear transmission box 9 is provided with a first drive wheel 15, a second drive wheel 16, and a third drive wheel 17. The first drive wheel 15, the second drive wheel 16, and the third drive wheel 17 are coaxially connected to the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6, respectively. The first drive wheel 15 is provided with a first transmission belt 13 that is connected to the second drive wheel 16. The second drive wheel 16 is provided with a second transmission belt 18 that is connected to the third drive wheel 17. The third drive wheel 17 is connected to the internal mixing motor 7. Specifically, the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6 are each provided with two stirring blades 14. The first drive wheel 15, the second drive wheel 16, and the third drive wheel 17, in conjunction with the first transmission belt 13 and the second transmission belt 18, cause the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6 to rotate and stir in the same direction. This causes the mixture to be stirred and transferred from above the first stirring rod 4 to above the second stirring rod 5, then from above the second stirring rod 5 to above the third stirring rod 6, then from below the third stirring rod 6 to below the second stirring rod 5, and finally from below the second stirring rod 5 to below the first stirring rod 4, thus performing a cyclical stirring process. Example 3

[0021] like Figures 6-8As shown, the structural features differ from other embodiments in that: the gear transmission box 9 is provided with a first drive wheel 15, a first helical gear 19, a first gear 10, and a second gear 11. The first drive wheel 15, the first helical gear 19, and the first gear 10 are coaxially connected to the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6, respectively. The second gear 11 meshes with the first gear 10. The first drive wheel 15 is provided with a first transmission belt 13 that is connected to the second gear 11. The first gear 10 is connected to the internal mixing motor 7. The gear transmission box 9 is provided with a forward and reverse motor 20. The output end of the forward and reverse motor 20 is located inside the gear transmission box 9 and is provided with a second helical gear 21. The first helical gear 19 meshes with the second helical gear 21. Specifically, the first stirring rod 4, the second stirring rod 5, and the third stirring rod 6 are each provided with two stirring blades 14. The first drive wheel 15 and the second gear 11 work together to make the first stirring rod 4 and the third stirring rod 6 rotate in opposite directions to stir the mixture, so that the mixture will gather between the first stirring rod 4 and the third stirring rod 6. The output control of the forward and reverse motor 20 enables the second stirring rod 5 to rotate in both directions, that is, it rotates in opposite directions before the first stirring rod 4 and then rotates in opposite directions with the third stirring rod 6 to achieve uniform mixing.

Those skilled in the art should understand that this invention is not limited to the above embodiments.
