One, use
    SH series mixing unit, mainly used for mixing and coloring of polyvinyl chloride resin, coloring and drying of polyethylene and polypropylene particles, such as hygroscopic resin such as ABS, polycarbonate, drying before processing, mixing of phenolic resin, etc. And then cooling it with cooling to prevent agglomeration, preventing the degradation of the hot mix material, allowing the additive in the hot mix material to continue to penetrate into the plastic resin, to remove residual gas from the hot mix material, and to store the hot mix material Cooling speed, cooling uniformity of the characteristics of the unit stable and reliable, durable, easy to operate, compact structure, etc., to meet the requirements of plastic production process, is used for a variety of plastic products industry in the ideal equipment.

Third, the main structure Description:
   The unit consists of rack, drive, pot body, lift, discharge and electrical control box composed of seven parts. The machine adopts a closed structure, the thermal mixer and the cooling mixer are compact and arranged to save space. The motor of the hot mixer is assembled within the platform and the structure is more reasonable. The platform provides enough space for operating the machine and storing other items The (See Figure 1).
   The pan body is made of stainless steel, the inner surface is extremely smooth and hard, with wear resistance, corrosion resistance, easy sticky material and so on. Hot mixing machine pot with heating sleeve and resistance heating ring temperature is heated by the jacket in the high-ignition heat transfer oil to the pot body, so that the pot heat evenly, adjust the heating temperature can control the temperature of the pot material. The jacket is covered with asbestos insulation. The cold mixers do not cool the jacket and cool through the cooling water to achieve the effect of cooling.
   The hot mixers are made of aluminum alloy. The inner surface is polished by fine car, which is rotated from the cylinder and can be rotated horizontally in the vertical direction (rotated by 70 ℃). The lid is covered with resin, plasticizer, stabilizer hole and ventilation hole. According to their own arrangements. Do not use the lid too much force to prevent bumps against the pot wall. In order to prevent the lid is not covered, stirring liquid rotation caused by personal accident, especially set the motor protection. The lower part of the cold mixer is a cooling ring, and the material is cooled by circulating water.
   The heat mixer baffle is used to enhance the mixing effect. The baffle has a nearly streamlined surface, and the baffle affects the flow of the material. Its most advantageous position depends on the material to be mixed. The baffle in the pot body can be freely adjusted in the diversion angle and can be adjusted vertically, the external clamping device, fixed deflector angle. The thermocouple is assembled in the deflector and its connection is led out through the conduit to the terminal head and connected to the thermometer of the electronic control box. The material temperature can be read on the indicator meter for automatic control of the output port Unloading. (See Figure 2)
   The hot mixer is stirred and driven by the motor via the triangular belt. The motor is AC two-speed motor, simply press the low, high speed button to achieve low speed. But must pay attention to: To high-speed rotation, the motor should be low-speed start stable, then high-speed start. The spindle is supported by two deep groove bearings. The upper part of the spindle has three mixing pulp, it is clockwise rotation, so that the material along the pot wall rotation, but also up and down the cycle of turning, coupled with the role of the baffle, the mixing effect is better, because the material is high-speed rotation, Between the material and the friction between the pulp and the heat is very large, it makes the material temperature rose rapidly, not only the corresponding reduction in the pot wall heating, but also conducive to the resin on the plasticizer absorption effect. Mixing pulp is made of stainless steel, and after careful mechanical processing, polishing, wear, corrosion resistance.
   The drive part of the cooling mixer is driven by the starting motor via the triangular belt. Through the gear box to the spindle, so that the mixing of hot mix material, the rack with adjustable handle, adjustable transmission V-belt tape elastic, open the door can be replaced with V-belt and mounting frame fixed and maintenance, maintenance purposes.
   The material is made of aluminum alloy. Each equipped with a pneumatic discharge door, connected by the cylinder and discharge door line. Compact and reliable, good sealing, opening and closing flexible. Use a 0.39-0.49Mpa air compressor one (by the user self). Discharge method can be automatically controlled by the temperature inside the pot, with the button to manually control the two ways to control the discharge gate opening and closing, fixed on the base of the outlet cover has a hose nozzle blowing head , Which is used to blow off (with compressed air) attached to the mixing port within the material.
