Caustic soda flake packaging machine

Abstract

The invention discloses a caustic soda flake packaging machine. A feeding and weighing device conducts feeding through a spiral feeding machine, and a weighing barrel receives materials discharged bythe spiral feeding machine and weighs the materials. After grabbing hands grab a packaging bag which is horizontally placed, the packaging bag is rotated to be located at the vertical position. An absorption disc absorbs a bag opening, a bag opening stretching device transversely moves to open the bag opening, and the opened packaging bag is tightly pressed on the weighing barrel in the circumferential direction by a clamping device. A bag supporting platform moves upwards when material filling operation is conducted, the bag supporting platform moves downwards when the material filling operation is accomplished, the bag supporting platform bears the packaging bag all the time in the blanking process, and the phenomenon that due to the fact that the packaging bag suddenly drops, the impactfall happens is avoided. The bag supporting platform can vibrate in the material filling process, and the materials can be evenly dispersed in the packaging bags. The air in the space located above the materials can be pressed out of the packaging bag by an air exhaust transfer device. When a conveying belt drives the packaging bag to arrive at an opening sealing device, the opening sealing device is used for sealing the bag opening of the packaging bag, and the packaging process is accomplished. The automatic weighing, filling and packaging operation of the materials is achieved, the automatic operation is achieved, and the packaging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of product packaging, and further relates to a caustic soda packaging machine. Background technique [0002] The chemical name of caustic soda is sodium hydroxide. It is a white translucent flake solid. It is a basic chemical raw material. , rubber and chemical industries, oil drilling, refining petroleum oils and refining tar oil industry. [0003] Because caustic soda has extremely strong corrosiveness and strong hygroscopicity, it is not suitable for manual weighing and packaging, and traditional weighing methods require more manual participation, and it is difficult to ensure sufficient accuracy; for those skilled in the art, How to design a kind of equipment that can automatically pack caustic soda is a technical problem to be solved at present. Contents of the invention [0004] The invention provides a caustic soda packaging machine, which can realize automatic packaging of caustic soda, and the s...
