Q1: What is the basic structure of a vacuum kneading machine?
The vacuum kneading machine is mainly composed of six parts:
Kneading part: including cylinder body, paddle shaft (usually Z-shaped or Sigma-shaped), wallboard, cylinder cover, etc., responsible for mixing and shearing materials.
Transmission system: composed of motor, reducer and gear, driving the paddle to rotate.
Hydraulic system: the cylinder is used to control the opening and closing of the cylinder cover and the turning of the mixing cylinder, and the design pressure can reach 7.0MPa.
Vacuum system: used to maintain a vacuum environment during the kneading process to prevent material oxidation or bubble generation.
Electronic control system: supports manual/automatic control, and some models are equipped with PLC to monitor temperature, time and other parameters in real time.
Machine base part: fix the equipment and provide stability.
Q2: What is the working principle of the vacuum kneading machine?
Through a pair of Z-shaped or Sigma-shaped paddles with different speeds, strong shearing, extrusion and stirring are applied to high-viscosity materials to make the materials quickly mixed and evenly mixed. The vacuum environment can prevent the material from generating bubbles or oxidation at high temperature or during the reaction process.
Q3: What industries and materials are suitable for vacuum kneading machines?
The main application areas include:
Chemical industry: sealants, silicone rubber, glass glue, resins, plastics, etc.
Medicine and cosmetics: ointments, creams, cosmetic bases.
Food industry: chewing gum, bubble gum, food gum base.
Other fields: battery slurry, ink, pigment, carbon materials, etc.
Q4: How to choose a suitable vacuum kneading machine model?
The following parameters should be considered for selection:
Capacity: From laboratory small machine (1L) to industrial large machine (6000L).
Material: carbon steel, stainless steel (such as SUS304) or special material, selected according to the corrosiveness of the material.
Heating method: electric heating, steam, thermal oil or water cooling.
Discharging method: hydraulic cylinder flipping, ball valve discharging, screw extrusion, etc.
Control mode: manual, automatic or PLC intelligent control.
Q5: What are the maintenance points of the vacuum kneading machine?
Lubrication management: Regularly add lubricating oil to bearings, gears and other components.
Cleaning and inspection: Clean the residual material in the cylinder after each use and check whether the fasteners are loose.
Sealing maintenance: Regularly check the shaft seal and vacuum system to prevent leakage.
Electrical system: Ensure that the electronic control components are dry to avoid short circuits.
Q6: What safety precautions should be taken when operating a vacuum kneading machine?
Pre-start inspection: Confirm that the equipment has no abnormal noise and the hydraulic system pressure is normal.
Operation monitoring: Avoid overload operation and deal with abnormal vibration or temperature rise in time.
Discharging operation: Ensure that personnel are away from dangerous areas when hydraulically turning the cylinder.
Comply with regulations: Strictly operate in accordance with technical standards and safety specifications.
Q7: What are the common types of vacuum kneading machines?
By function: ordinary type, pressure type, vacuum type, high temperature type.
By material: carbon steel, stainless steel, special alloy (such as titanium alloy).
By discharging method: hydraulic cylinder turning type, screw extrusion type, ball valve type.
Q8: What is the price range of the vacuum kneading machine?
The reference price of the basic model starts at about 10,000 yuan (such as 5L capacity), and the price of industrial-grade large-scale equipment can reach tens of thousands to hundreds of thousands of yuan, depending on the configuration (such as PLC control, special materials).
Q9: Does the vacuum kneading machine support customized needs?
Yes. Manufacturers can customize capacity, materials, heating methods and control systems according to needs, such as explosion-proof type, variable frequency speed regulation type or special industry-specific models.
