Description

Technical Field

[0001] The utility model relates to the technical field of triangular rotors, in particular to a triangular rotor for a kneading machine. Background Art

[0002] The triangular rotor is a rotor structure used in internal mixers, also known as a triangular rotor. It is the core part of the internal mixer, playing the role of stirring, cutting, flipping and mixing materials. The triangular rotor is usually composed of three equal length edges and corners, and its shape is similar to a triangular cone. Its structural design has an important influence on the performance and effect of the entire internal mixer system. Through different speeds, rotor shapes and arrangements, different materials can be processed and mixed.

[0003] A kneading machine is a device used for plasticizing and mixing materials such as rubber and plastic. It is suitable for mixing and kneading viscous materials. The rotor in the kneading machine has a high operating intensity. When the three-sided rotor is in operation, the part that is most worn is the gear ring inside it, rather than the three edges of the three-sided rotor that are in contact with the operating chamber. In the prior art, the gear ring is fixed inside the Lelo triangle. When the gear ring is worn, it is impossible to maintain or replace the gear ring.

[0004] For this reason, we propose a three-edge rotor for a kneading machine. Utility Model Content

[0005] The utility model mainly solves the above technical problems and provides a three-edge rotor for a kneading machine.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a three-sided rotor of a kneading machine, comprising a shell and a center gear, the center gear being fixedly distributed at the internal center point of the shell, a Lelo triangle being arranged inside the shell, a connecting port being opened at the center point of the Lelo triangle, an annular groove being opened on the inner wall surface of the connecting port, a gear ring being detachably installed inside the Lelo triangle, the inner side surface of the gear ring being a serrated surface, a flange being opened on the outer circle of the gear ring, the three outer side surfaces of the Lelo triangle being penetrated by arc-shaped installation ports connected to the inside of the connecting port, the Lelo triangle being meshingly connected with the center gear through the gear ring.

[0007] Preferably, the gear ring is installed inside the connecting port through an arc-shaped installation port, a plurality of fastening holes are penetrated through the flange, and a plurality of installation holes are also provided on the front and rear sides of the Lelo triangle.

[0008] Preferably, fixed sealing columns are fixedly mounted on the Lelo triangle, and the fixed sealing columns are distributed at three edge positions close to the Lelo triangle.

[0009] Preferably, a plurality of groups of movable sealing columns made of rubber are rotatably mounted on the outer side surface of the Lelo triangle.

[0010] Preferably, a plurality of groups of movable sealing columns are sequentially arranged and distributed at corresponding edge positions on the outer surface of the Lelo triangle.

[0011] Beneficial Effects

[0012] The utility model provides a three-edged rotor for a kneading machine, which has the following beneficial effects:

[0013] (1) In the kneading machine, the three outer corners of the Lelo triangle move along the inner side of the operating chamber when the three-edge rotor is in operation. Since the friction and wear at the meshing connection between the gear ring and the center gear is the greatest when the three-edge rotor is in operation, the gear ring can be freely disassembled to facilitate people to replace the gear ring, thereby achieving the effect of facilitating maintenance and replacement of the gear ring of the wearing part.

[0014] (2) In the three-sided rotor of the kneading machine, when the Lelo triangle is in operation, the Lelo triangle contacts the inner side surface of the operating chamber through multiple sets of movable sealing columns, thereby improving the smoothness of the Lelo triangle during operation, thereby achieving the effect of improving the smoothness of the operation of the three-sided rotor.

[0022] 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.

[0023] Embodiment: A kneading machine three-edged rotor, such as Figure 1-Figure 3 As shown, it includes a shell 1 and a central gear 9, and the central gear 9 is fixedly distributed at the inner center point of the shell 1. A Lelo triangle 3 is arranged inside the shell 1, and a connecting port 5 is opened at the inner center point of the Lelo triangle 3. An annular groove 51 is opened on the inner wall surface of the connecting port 5. A gear ring 4 is detachably installed inside the Lelo triangle 3. The inner side surface of the gear ring 4 is a serrated surface, and a flange 41 is arranged on the outer circle of the gear ring 4. The three outer side surfaces of the Lelo triangle 3 are penetrated with an arc-shaped installation port 6 connected to the inside of the connecting port 5. The gear ring 4 is installed to the inside of the connecting port 5 through the arc-shaped installation port 6. A plurality of groups of fastening holes are penetrated on the flange 41. A plurality of groups of installation holes 10 are also opened on the front and rear sides of the Lelo triangle 3. When installing the gear ring 4, the gear ring 4 is set to the connecting port through the arc-shaped installation port 6. Inside the interface 5, the flange 41 will be distributed in the annular groove 51, and the gear ring 4 will be fixedly installed in the connection port 5 through the external fastening bolts passing through the multiple sets of mounting holes 10 that overlap inside and outside. The gear ring 4 is meshed and connected with the central gear 9 through the serrated surface set on the inner side. When the driving mechanism controls the Lelo triangle 3 to make a circular motion, the Lelo triangle 3 is meshed and connected with the central gear 9 through the gear ring 4, so that the central gear 9 limits the movement path of the Lelo triangle 3, so that the Lelo triangle 3 makes a circular motion while automatically, and the three outer edges of the Lelo triangle 3 move along the inner side of the running chamber 2 when the three-angle rotor is running. Because the friction and wear at the meshing connection between the gear ring 4 and the central gear 9 is the greatest, by setting a freely detachable gear ring 4, it is convenient for people to replace the gear ring 4;

[0024] A fixed sealing column 7 is fixedly installed on the Lelo triangle 3, and the fixed sealing column 7 is distributed at three edge positions close to the Lelo triangle 3. A plurality of groups of movable sealing columns 8 made of rubber material are rotatably installed on the outer side surface of the Lelo triangle 3. The plurality of groups of movable sealing columns 8 are arranged in sequence and distributed at the corresponding edge positions of the outer side surface of the Lelo triangle 3. When the Lelo triangle 3 is running, the Lelo triangle 3 contacts the inner side surface of the running cavity 2 through the plurality of groups of movable sealing columns 8, thereby improving the smoothness of the Lelo triangle 3 during operation.

[0025] The working principle of this utility model:

[0026] When the Lelo triangle 3 is in operation, the three outer corners of the Lelo triangle 3 move along the inner side of the operating chamber 2. When the three-cornered rotor is in operation, the friction and wear at the meshing connection between the gear ring 4 and the center gear 9 is the greatest. By providing a freely detachable gear ring 4, it is convenient for people to replace the gear ring 4.

[0027] When the Reuleaux triangle 3 is in operation, the Reuleaux triangle 3 contacts the inner side surface of the operation chamber 2 through a plurality of groups of movable sealing columns 8, thereby improving the smoothness of the Reuleaux triangle 3 in operation.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
