Description

Technical Field

[0001] This utility model is an internal mixer with an adjustable working chamber position, belonging to the field of internal mixer technology. Background Technology

[0002] Internal mixers are industrial equipment used for the plasticizing and mixing of rubber and plastics, and are mainly used in industries such as tires, seals, cables, and hoses.

[0003] When using an internal mixer, because there are many raw materials and diverse formulas involved in rubber internal mixing, conventional internal mixers usually require multiple mixers or need to be cleaned after each step before they can be used. This results in cumbersome work steps and low efficiency. Therefore, to address the above situation, an internal mixer with an adjustable working chamber position is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an internal mixer with an adjustable working chamber position to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an internal mixer with an adjustable working chamber position, the structure of which includes a mixing chamber, a first feed inlet, a first discharge outlet and a motor on the mixing chamber, a connecting frame connected to the mixing chamber and a small mixing chamber connected to the connecting frame, the small mixing chamber being provided with a second motor, a second feed inlet and a second discharge outlet. The feed inlet, discharge outlet and motor are all conventional settings and can all be switched on and off by electronic control. This is conventional technology and therefore will not be described in detail.

[0006] Furthermore, a conveying pipe is connected to the second discharge port, and the conveying pipe connects the second discharge port to the mixing chamber.

[0007] Furthermore, there are two motors arranged side by side, and the output shafts of both motors extend into the mixing chamber and are connected to a first stirring rod.

[0008] Furthermore, a rotating rod is rotatably connected inside the small mixing chamber, and the rotating rod is connected to the output shaft of the second motor. Several second stirring rods are equidistantly distributed on the rotating rod.

[0009] Furthermore, the small mixing chamber is also provided with several fixed rods, which are arranged alternately and located between two adjacent rotating rods.

[0010] Furthermore, the first stirring rod is provided with stirring blades, which are arranged alternately in front and left on the first stirring rod. There is a gap between two stirring blades on the same straight line. The two first stirring rods are arranged side by side, and the stirring blade on one of the first stirring rods is located in the gap of the other first stirring rod.

[0011] Furthermore, the tip structure of the second stirring rod and the fixing rod is rhomboid.

[0012] The beneficial effects of this utility model are:

[0013] 1. By having two chambers, a deep mixing chamber and a small deep mixing chamber, the two chambers can work independently or in combination, which not only greatly improves flexibility but also increases efficiency during deep mixing.

[0014] 2. The mixing chamber is the main mixing chamber and the chamber is relatively large. Therefore, two first stirring rods are set to rotate in the same direction. Since the gap between the first stirring rod and the inner wall of the mixing chamber is large, a "tangential shearing" zone is formed, which can effectively break up the compounding agent clumps and promote dispersion.

[0015] 3. The small mixing chamber is a secondary mixing chamber and is relatively small. Therefore, a second stirring rod and a fixed rod are set up to work together in an alternating manner. The two work together to form a "scissor-like" shearing zone. The surface of both rods has a prismatic shape and the gap between the ridge and the inner wall of the mixing chamber is extremely small, ensuring that the material is forcibly sheared.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-5 This utility model provides a technical solution for an internal mixer with an adjustable working chamber position: its structure includes an internal mixing chamber 1, the internal mixing chamber 1 is provided with a first feed port 2, a first discharge port 3 and a motor 4, the internal mixing chamber 1 is connected to a connecting frame 5 and a small internal mixing chamber 6 is connected to the connecting frame 5, and the small internal mixing chamber 6 is provided with a second motor 7, a second feed port 8 and a second discharge port 9;

[0025] The second discharge port 9 is connected to a conveying pipe 10, which connects the second discharge port 9 to the mixing chamber 1.

[0026] Two motors 4 are provided and arranged side by side. The output shafts of both motors 4 extend into the mixing chamber 1 and are connected to a first stirring rod 11. The first stirring rod 11 is provided with stirring blades 15. The stirring blades 15 are arranged alternately in front and left on the first stirring rod 11. There is a gap 16 between two stirring blades 15 on the same straight line. The two first stirring rods 11 are arranged side by side and the stirring blade 15 on one of the first stirring rods 11 is located in the gap 16 of the other first stirring rod 11.

[0027] The small mixing chamber 6 is rotatably connected to a rotating rod 12, which is connected to the output shaft of the second motor 7. Several second stirring rods 13 are equidistantly distributed on the rotating rod 12. Several fixed rods 14 are also provided in the small mixing chamber 6. Each fixed rod 14 is alternately arranged and located between two adjacent rotating rods 12. The tips of the second stirring rods 13 and the fixed rods 14 are rhomboid in shape.

[0028] For example, during use, different materials required for mixing can be added to the mixing chamber 1 and the small mixing chamber 6 respectively. After working separately, the materials in the small mixing chamber 6 are sent to the mixing chamber 1 through the second discharge port 9 and the conveying pipe 10 for mixing, thereby ensuring the crushing effect of the materials and the uniformity of the mixture.

[0029] Alternatively, only the mixing chamber 1 can be used for operation, while the small mixing chamber 6 can serve as a material chamber, where materials are only added to the mixing chamber 1.
