Description

Technical Field

[0002] Closed plastic refining machine is referred to as internal mixer. The main component of the internal mixer is the internal mixing chamber, also known as the plastic refining chamber, with a feeding device on the upper part and a discharge device on the lower part, and a bolt on the upper and lower parts; when the upper and lower bolts are closed, a closed plastic refining chamber is formed. There is a pair of rotors rotating in opposite directions in the plastic refining chamber. The rotors are pear-shaped in cross section and Z-shaped spirals along the longitudinal direction. The rotor speeds are slightly different, and there is a constant speed ratio between the rotors and between the rotors and the inner wall of the plastic refining chamber. There is a cooling (heating) jacket on the outer wall of the plastic refining chamber to heat and cool the materials. Due to the limitation of the on-site space, it is very inconvenient to clean the pressure weight of the internal mixer. If the cleaning is not done properly, the powder will stick to the pressure support. When the internal mixer is discharged in the last step of the rubber refining process, the powder on the pressure support will occasionally fall into the internal mixer and be discharged from the internal mixer together with the plasticized rubber, which will have a serious impact on the product quality. Therefore, how to develop a feeding device for a closed plastic refining machine has become an urgent problem to be solved by technicians in this field. Utility Model Content
