Abstract

The invention discloses a gas-liquid pressurization device for a discharge door of an internal mixer, and belongs to the technical field of rubber internal mixers. The gas-liquid pressurization device for the discharge door of the internal mixer comprises a pneumatic hydraulic pump, wherein the pneumatic hydraulic pump is connected onto an oil inlet pipe of a hydraulic oil tank, and an oil inlet one-way valve and an oil filter are arranged on the oil inlet pipe; an oil outlet one-way valve, an energy accumulator, an electromagnetic reversing hydraulic valve and an oil cylinder of a discharge door locking mechanism are sequentially connected on an oil outlet pipe of the pneumatic hydraulic pump in series; and a liquid return pipeline connected onto the oil cylinder of the discharge door locking mechanism penetrates through the electromagnetic reversing hydraulic valve and is connected into the hydraulic oil tank. According to the gas-liquid pressurization device for the discharge door of the internal mixer, the discharge door locking mechanism can be opened and closed rapidly and reliably, stops operating automatically when set pressure is up to, automatically returns to work when pressurization is required, and doesn't consume energy when the locking mechanism stops operating.

Description

Technical field

[0001] The invention relates to the technical field of rubber-plastic internal mixers, in particular to a novel transmission device for locking the discharge door of the internal mixer, which can quickly and reliably realize the opening and closing of the discharge door locking mechanism, and is suitable for full-pressure driven Used in internal mixers. Background technique

[0002] Closed rubber mixing (plastic) mixer is abbreviated as internal mixer, which is an important equipment for rubber and plastic processing. Mainly used for mixing rubber or plastic with compounding agents. The internal mixer adopts the intermittent circulation method for mixing work. In each working cycle, the feeding mechanism, the pressing mechanism and the unloader should coordinate their actions accurately and reliably. The actions of these structures are generally driven by compressed air or hydraulic oil. The old low-pressure and low-speed internal mixer is driven by full air pr...
