Main equipment used in the production of PVC floor tiles by calendering
1. High speed kneading machine
The high-speed kneader is a device that performs high-speed stirring and kneading of the solid-liquid mixture to be charged in a closed container. High-speed kneading machines have capacities of 10L, 50L, 100L and 200L. It can be used for dispersion mixing of wet and non-lubric materials. The number of rotations of the paddle can reach 900r/min. Heating methods include electric heating, oil heating, steam heating, and the like.
Its main components:
The mixing pot is a jacket structure welded from a boiler steel plate with a smooth inner surface. The jacket is used to pass a heating or cooling medium to ensure the temperature required for the material to mix in the pot. The jacket is covered with insulation and insulation material.
The stirring device is generally composed of two stirring blades, and its function is to rotate the stirring material at a high speed under the driving of the motor. The stirring device is placed at the bottom of the mixing pot.
Discharge device: When the discharge valve is closed, the valve and the mixing pan are integrated to form a dense and non-leaking pot. When the materials are mixed, the valve is disengaged from the pot and discharged.
The main function of the baffle is to block the material moving in a circular motion, resulting in fluidized motion and promoting uniform mixing of the materials.
2. Internal mixer
The internal mixer is mainly composed of a mixing chamber, a rotor, a pressing device, a discharging device, a heating and cooling device, and a transmission system. The internal mixer is characterized by being able to give the material a large shear energy in a short period of time and to masticate in the case of insulating air, which is superior to labor conditions, mastication effect and prevention of material aging. Open mill. The total capacity of the internal mixer is 4.3 to 75 L or more.
3. Two-roller simple plastic mixer
The main component of the mastication operation in the machine is a pair of parallel rollers with opposite rotation directions. The length to diameter ratio is about 2.5, the rotation speed is 17 to 20r/min, and the front and rear roller rotation ratio is 1: (1.05 to 1.10). There is a circulation heating or cooling carrier in the cylinder. The roller diameter is 160 to 550 m or more.
The plastic mixer mainly subjects the material to shear stress, squeezing force and heating, so that the material is mixed and masticated. In the industry, the raw materials are mixed and plasticized by a plasticizer to produce semi-finished products, or for calendering.
4. Two-roll calender
The structural features are the same as the double roller plastic mixer. In addition, there are auxiliary machines for calendering: lead-off devices, cooling devices, conveyor belts, printing embossing devices, tension rollers, punching machines, etc.
