Silicone Kneading Machine Introduction

The silicone kneading machine is a mixing equipment specially designed for the characteristics of materials such as silicone and mold glue. It is an ideal equipment for kneading silicone and mold glue. The following is a detailed introduction:

1. Working principle:
- The silicone kneading machine mainly relies on a pair of rotating blades (usually in Z shape or sigma shape) that cooperate with each other to produce a strong shearing effect. During the rotation of the blades, the semi-dry or rubbery and viscous plastic materials, silicone and other materials are stirred to make the materials react quickly, thereby obtaining a uniform mixing effect. During stirring, it not only has a shearing effect on the materials, but also extrude and crush the block materials, so that the materials can be fully mixed and kneaded.
2. Structural composition:
- Kneading part: It is composed of a cylinder body, a paddle shaft, a wall panel, a cylinder cover, etc., and is the main place for material kneading. The shape and size of the cylinder body are designed according to different production requirements. The shape and arrangement of the blades on the paddle shaft are also key factors affecting the kneading effect.
- The base part: It plays the role of supporting and fixing the entire equipment to ensure the stability of the equipment during operation.
- Hydraulic system: Usually a hydraulic station is used to operate the oil cylinder, which is responsible for opening and closing the large cover, turning the mixing cylinder, etc., to facilitate operations such as feeding, discharging, and cleaning and maintenance of the equipment.
- Transmission system: It consists of a motor, a reducer and gears, and a motor of corresponding power is matched according to the model of the kneading machine. During the transmission process, the synchronous speed of the motor is transmitted to the reducer through the elastic coupling, and the output device drives the fast slurry to reach the specified speed. Some kneading machines can also be adjusted by frequency converters to meet the mixing requirements of different materials.
- Vacuum system: For some silicone materials that need to be kneaded in a vacuum environment, the kneading machine is equipped with a vacuum system, which can extract the air in the equipment, eliminate the bubbles generated by the material during the mixing process, and improve the quality of the material.
- Electronic control system: There are manual and automatic electronic control systems for users to choose from, which are easy and reliable to operate and can monitor and control the operating status of the equipment.
3. Scope of application: widely used in the mixing, kneading, crushing, dispersion, repolymerization and other processes of various high-viscosity elastic-plastic materials, such as high-viscosity sealants, silicone rubber, neutral acid glass glue, fiber rubber and other industries. In the food field, it can be used for the production of chewing gum, jam, chocolate and other products; in the toy industry, it can be used to make clay, plasticine, etc.; in the electronic and electrical appliances, it can be used for the processing of electronic silicone and battery slurry.
4. Temperature adjustment method: generally there are jacket, steam, oil heating, water cooling and other methods. For silicone kneading machines with smaller volumes, it is recommended to use jacket electric heating structure; for large kneading machines, circulating heat transfer oil heating and other methods can be used.
5. Discharging method: including hydraulic cylinder dumping, ball valve discharging, screw extrusion, hydraulic flap discharging, etc. Among them, the screw discharging kneading machine is equipped with a push screw in the bottom discharging trough, and the material is pushed to the outside of the box by the rotation of the screw.
6. Equipment maintenance:
- After installation, first clean, decontaminate and wipe the anti-rust grease, check each lubrication point, and inject lubricating oil (grease).
- Before driving, check the tightness of the V-belt and move the motor to the appropriate position by adjusting the bolts; at the same time, check whether the fasteners are loose, whether the steam pipe is leaking, and whether the circuit and electrical equipment are safe.
- When using steam for heating, a safety valve and a pressure gauge should be installed at the inlet pipe, and the steam pressure should not exceed the mixing tank use pressure requirements.
- During the operation of the equipment, each lubrication part should be frequently oiled, and attention should be paid to the wall panel sealing part without raw material leakage.

Our advantages:

1. Good mixing effect:
- Uniform mixing: A pair of rotating blades (usually in Z-shape or Sigma-shape) that cooperate with each other can produce a strong shearing effect, so that the material is fully sheared, squeezed and folded during the kneading process, allowing the material to react quickly, thereby obtaining a uniform mixing effect. Whether it is a high-viscosity material or a variety of materials with different ingredients, high-quality mixing can be achieved.
- No dead angle stirring: The special blade design and stirring method ensure that the material inside the kneader can be fully stirred, there is no stirring dead angle, and the consistency of the product is ensured.
2. High kneading efficiency:
- Reasonable structural design: The overall structural design of the silicone kneader, such as the transmission system composed of motors, reducers and gears, can provide sufficient power and stable speed for the stirring paddle, so that the stirring process can be carried out efficiently; at the same time, its reasonable layout and compact structure reduce energy loss and improve the operating efficiency of the equipment.
- Large capacity design: Some large silicone kneaders have a large working capacity and can process a large amount of silicone materials at one time, meeting the needs of large-scale production, reducing the number of frequent feedings, and improving production efficiency.
3. Strong adaptability:
- Applicable to a variety of materials: not only suitable for silicone, mold glue, etc., but also widely used in high-viscosity sealants, neutral acid glass glue, fiber rubber, chewing gum, toothpaste, plastics, dyes, pigments, inks, food glue bases, pharmaceuticals, architectural coatings and other high-viscosity elastic-plastic materials mixing, kneading, crushing, dispersion, repolymerization and other processes.
- Can meet different process requirements: According to the needs of the production process, different heating methods (such as electric heating, steam heating, circulating hot oil heating, etc.) and discharging methods (such as hydraulic cylinder dumping, ball valve discharging, screw extrusion, etc.) can be selected, and can be made into three types of vacuum, pressure, and normal pressure to meet the kneading needs of different materials under different process conditions.
4. Convenient operation:
- High degree of automation: Some silicone kneading machines are equipped with automatic control systems, such as automatic feeding, automatic stirring and automatic discharging, which greatly reduces the tediousness of manual operation and reduces labor intensity, while also improving the stability and accuracy of production.
- Easy to operate: The operation interface of the equipment is simple and clear. The operator can master the operation method of the equipment after simple training, which is easy to use.
5. Reliable equipment quality:
- Made of high-quality materials: The cylinder body and the paddle blades that contact the material are usually made of high-quality stainless steel materials such as SUS304 or SUS316L, which have good corrosion resistance and wear resistance, ensuring the long service life of the equipment and ensuring that the quality of the product is not affected by the material of the equipment.
- Good performance of key components: Key components such as motors, reducers, electrical control systems, etc. are made of well-known domestic and foreign brands, ensuring the stable operation of the equipment and reducing the failure rate of the equipment.
6. Easy to maintain and clean:
- The structure is easy to disassemble: The structural design of the equipment is easy to disassemble and assemble, which is convenient for maintenance and cleaning of the inside of the equipment, reducing the time and cost of equipment maintenance.
- Easy to clean materials: The smooth surface of the cylinder body and paddle blades is not easy to adhere to the material, so that the kneaded material can be discharged smoothly, reducing the residue of the material inside the equipment, which is convenient for the next use.
