Internal mixer discharge door shaft structure

Abstract

The invention discloses an internal mixer discharging door shaft structure. The structure comprises a door shaft and a discharging door; the left side of the bottom of the discharging door is fixedly mounted with a first door seat; the right side of the bottom of the discharging door is fixedly with a second door seat; discharging door shaft is composed of an active door shaft and a driven door shaft; one end of the active door shaft is installed with a rotation oil cylinder, and the other end of the active door shaft is fixedly arranged in the first door seat; one end of the driven door shaft is fixedly arranged in the second door seat and extends outside, and the other end of the driven door shaft is provided with a swivel joint; and a water circulation pipeline is arranged in the swivel joint, the driven door shaft and the discharging door shaft. According to the above discharging door shaft structure of the internal mixer, the active door shaft and the driven door shaft have low processing precision requirements and long usage life, so as to substantially reduce processing cost and facilitate installation and maintenance of the discharging door shaft.

Description

technical field [0001] The invention relates to an internal mixer, in particular to an internal mixer discharge door shaft structure. Background technique [0002] The internal mixer is mainly used for plasticizing and mixing of rubber, and can also be used for mixing of plastics, asphalt materials, linoleum materials, enamel materials and various synthetic resins. During the working process of the internal mixer, the discharge door needs to be opened and closed intermittently to realize the cycle of discharging and loading of the internal mixer. The opening of the discharge door is realized by rotating the shaft of the discharge door through the rotating cylinder. The traditional The shaft of the discharge door is a long shaft as a whole. There are many shoulders with different diameters processed on the shaft. There is a door seat at both ends of the bottom of the discharge door, and the shaft of the discharge door passes through the two doors. seat, and one of the door s...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of the discharge door shaft structure of the internal mixer with the above structure are: the length of the discharge door shaft is long, and there are many shoulders with different diameters processed on the shaft, which makes the machining accuracy of the shaft higher. It is difficult to ensure the shape accuracy of the shaft during the machining process. The shape accuracy error will cause uneven force on the discharge door shaft and accelerate the wear of the discharge door shaft, thereby reducing the service life of the discharge door shaft; in addition, because the discharge door shaft It is a long shaft as a whole, and the operation is very complicated during installation and maintenance
