Internal mixer discharging 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] Banbury mixer is mainly used for plasticizing and mixing of rubber, and can also be used for mixing plastic, asphalt material, linoleum material, enamel material and various synthetic resins. During the working process of the internal mixer, it is necessary to open and close the discharge door intermittently to realize the cycle of discharging and charging of the internal mixer. The unloading door shaft is a long shaft as a whole. There are several shoulders with different diameters processed on the shaft. There is a door seat at each end of the bottom of the unloading door. The unloading door shaft passes through the two doors. One of the door seats is fixedly connected with the discharge door shaft to transmit torque. [0003] The main disadvantages of the unloading door shaft structure of the internal mixer w...

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
