Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, in t...

Abstract

The invention discloses a novel sealing structure for a piston rod of an internal mixer. The novel sealing structure for the piston rod of the internal mixer comprises an internal mixer main body, a shifting fork rod and a compensation mechanism. The internal mixer main body comprises a transition plate and a piston rod. The compensation mechanism is fixed to the transition plate and arranged on one side of the piston rod. The shifting fork rod is transversely arranged between the compensation mechanism and the piston rod. One end of the shifting fork rod is detachably connected with the compensation mechanism, and the other end of the shifting fork rod is used for being detachably connected with a sealing ring arranged on the piston rod in a sleeving manner. The compensation mechanism is used for driving the shifting fork rod to swing in the movement direction of the piston rod, and therefore the end, away from the compensation mechanism, of the shifting fork rod can press the sealing ring driven by the piston rod to the designated position. According to the technical scheme, the compensation mechanism drives one end of the shifting fork rod to press the sealing ring arranged on the piston rod in a sleeving manner all the time, force can be applied to the sealing ring for a long time, the sealing ring is kept in a sealed state, and manual inspection is not needed for sealing of the sealing ring.

Description

technical field [0001] The invention relates to the technical field of internal mixers, in particular to a novel internal mixer piston rod sealing structure. Background technique [0002] Most of the upper bolts of internal mixers are now in the form of hydraulic upper bolts, and because the piston rod needs to reciprocate up and down frequently, the internal powder will be sprayed out when the internal mixer is working, or the powder will stick to the paste. On the surface of the piston rod, causing the seal to fail. Therefore, the sealing of the piston rod of the internal mixer is very important to the appearance of the internal mixer. [0003] At present, the structure of the piston rod of the internal mixer is: the piston rod moves up and down in the flange sleeve, and the flange sleeve is fixed on the transition plate by bolts. In order to play a sealing role, there is a combined sealing ring in the flange sleeve. The composite sealing ring is made of cloth rubber, an...
