Cement clinker large bag packaging machine

Abstract

The invention discloses a cement clinker large bag packaging machine. The cement clinker large bag packaging machine comprises a stock bin which is fixed on a floor slab, a hopper, a double-arc valve and a double-layer filling casing pipe are sequentially installed at the bottom of the stock bin, the double-arc valve is provided with a valve body, a discharging pipe which stretches into an inner cavity is installed on the top of the valve body, a discharge port is formed in the bottom of the valve body, a large arc plate and a small arc plate are arranged at the bottom of the discharging pipe, rotating arms are arranged at the front end portions and the rear end portions of the large arc plate and the small arc plate and hinged to the valve body through rotating shafts, and the rotating shafts on one side stretches out from the valve body and is externally connected with a mechanical driving device to control opening and closing of the large arc plate and the small arc plate. An automatic bag clamping device is installed on the double-layer filling casing pipe, a roller table conveyor is arranged below the double-layer filling casing pipe, a lifting device is installed on the floor slab located on the right side of the stock bin and provided with a crossed hanging bracket in a hanging mode through a connecting rod, and a plurality of hanging hooks are arranged at the bottom of the hanging bracket and all provided with automatic unhooking devices. The cement clinker large bag packaging machine is high in filling accuracy, accurate in weighing, and mainly used for automatically filling cement clinker into a large packaging bag.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to a cement clinker large bag packaging machine. Background technique [0002] Cement clinker refers to the semi-finished product obtained by using limestone, clay and iron raw materials as the main raw materials, which are prepared into raw meal in appropriate proportions, burned until part or all of them are melted, and cooled. [0003] In the cement industry, clinker big bag packaging is a shipping technology between bulk and ordinary bag (50kg weight). At present, the traditional cement clinker big bag packaging machine includes a silo, which is fixed on the floor, and the bottom of the silo is sequentially connected with a hopper, a manual gate valve and a double-layer filling casing. The double-layer filling casing is equipped with Automatic bag clamping device, roller conveyor arranged under the double-layer filling casing. There is a lifting device hoisted on th...

Problems solved by technology

The cement clinker big bag packaging machine of this traditional structure adopts manual gate valve, which not only has poor sealing effect, high labor intensity, much dust, and slow filling speed, but also causes filling metering due to the manual gate valve not being closed in time. poor precision
