New aliphatic polyurethane paint mixing device

Abstract

The invention discloses an aliphatic polyurethane paint mixing device, which comprises a kettle and a kettle cover connected to the kettle. The aliphatic polyurethane paint mixing device is characterized in that a stirring shaft penetrates through the kettle cover, the stirring shaft outside the kettle cover is connected to a stirring motor, the stirring shaft inside the kettle cover is provided with a stirring paddle, a rotating wheel is arranged at the center of the bottom of the kettle, the rotating wheel is connected to a scraper which can rotate closely to the inner wall of the kettle, the rotating wheel is connected to a drive motor on the outer side of the kettle, and a liquid level sensor, a heater and a temperature sensor are also arranged in the kettle. According to the aliphatic polyurethane paint mixing device, the materials of the aliphatic polyurethane paint are uniformly mixed, residues on the kettle wall can be effectively cleared, situation of liquid level in the mixing kettle can be monitored in real time, meanwhile required temperature is provided for mixing the aliphatic polyurethane paint, and product quality is ensured.

Description

technical field [0001] The invention relates to the field of paint production equipment, in particular to a novel aliphatic polyurethane paint mixing device. Background technique [0002] The new aliphatic polyurethane paint mixing device is mainly used for mixing and toning the aliphatic polyurethane paint. The existing paint mixing device has a complex structure and single function, and is generally only placed along the inside of the paint mixing kettle. Rotating in one direction will cause the paint to be mixed unevenly, or make the color of the aliphatic paint color paste added to the mixing kettle mixed with the polyurethane paint in the kettle to be uneven, and because the paint generally has a certain viscosity The consistency makes it easy to stick to the inner wall of the paint mixing kettle during the mixing process. If it goes on for a long time, a thick layer of paint will accumulate on the wall of the kettle, which will not only waste raw materials, but also ea...

[0002] The new aliphatic polyurethane paint mixing device is mainly used for mixing and toning the aliphatic polyurethane paint. The existing paint mixing device has a complex structure and single function, and is generally only placed along the inside of the paint mixing kettle. Rotating in one direction will cause the paint to be mixed unevenly, or make the color of the aliphatic paint color paste added to the mixing kettle mixed with the polyurethane paint in the kettle to be uneven, and because the paint generally has a certain viscosity The consistency makes it easy to stick to the inner wall of the paint mixing kettle during the mixing process. If it goes on for a long time, a thick layer of paint will accumulate on the wall of the kettle, which will not only waste raw materials, but also easily damage the paint. Mixing Kettle Causes Damage

[0003] At the same time, the existing paint mixing device lacks a liquid level monitoring device in the mixing tank, and the operator cannot observe the liquid level in the mixing tank in time, resulting in the phenomenon that more materials are added and it is difficult to mix, and even the material liquid refluxes.

Moreover, the aliphatic polyurethane paint needs to be mixed at a certain temperature to complete a good mixing process. When the temperature is low, it is not conducive to its mixing and affects the product quality.
