Anti-oxidation batch filling system for coating material production line and filling method thereof

Abstract

The invention discloses an anti-oxidation batch filling system for a coating material production line and a filling method thereof. The anti-oxidation batch filling system for the coating material production line comprises a conveying device, a piston type filling head, an air exhausting device, a nitrogen supplying source, a coating material supplying source and a barrel lid buckling mechanism. The piston type filling head partially extends into a coating material barrel, so that a variable coating material filling space is formed between the bottom of the piston type filling head and the inner bottom of the coating material barrel. The air exhausting device is used for exhausting air in the variable coating material filling space. The nitrogen supplying source is used for feeding nitrogen into the variable coating material filling space to enable the variable coating material filling space to form a nitrogen filling environment. The coating material supplying source is used for filling the variable coating material filling space in the nitrogen filling environment with the coating material. A temporary seal barrel lid is buckled to a mouth of the coating material barrel through the barrel lid buckling mechanism to seal the coating material barrel containing the coating material. By the adoption of the anti-oxidation batch filling system for the coating material production line, the manner that the air is exhausted and then the nitrogen is filled is adopted, so that the variable coating material filling space of the coating material barrel can form the nitrogen filling environment, and therefore the phenomenon that the coating material is in contact with the air and is oxidized in the filling process is avoided.

Description

technical field [0001] The invention belongs to the technical field of paint production equipment, and in particular relates to an anti-oxidation batch filling system for a paint production line and a filling method thereof. Background technique [0002] Existing paint filling equipment has the following deficiencies: [0003] 1. There is no anti-oxidation protection to isolate the air during the filling operation, which leads to oxidation of the paint in contact with the air, which greatly affects the quality of the paint; [0004] 2. When the paint barrel or paint tank is in an open state during the transportation process, the upper paint will be oxidized directly in contact with the air, which will also affect the middle and lower paint in the barrel or tank, reducing the product qualification rate. [0005] Based on the above reasons, the present invention designs an anti-oxidation batch filling system and its filling method for the paint production line. The variable p...
