Description

Technical Field

[0001] The utility model belongs to the technical field of proportioning equipment for paint production, and particularly relates to a proportioning device for paint production. Background Art

[0002] The proportioning device used in paint production is one of the key equipment in the paint production line. It is responsible for accurately controlling the proportions of various raw materials to ensure the quality and performance of the paint products. The proportioning device used in paint production is widely used in various paint production lines, such as automotive paints, architectural paints, industrial paints, etc. There are many types of proportioning devices used in paint production, including manual or semi-automatic proportioning devices, flow control proportioning devices, volumetric proportioning devices, PLC-controlled intelligent proportioning systems, automatic weighing proportioning devices, etc.

[0003] Automatic weighing and proportioning devices are a very common and widely used type of device in paint production. Their principle is mainly based on the working principle of weighing sensors and computer control technology. Automatic weighing and proportioning devices achieve automatic proportioning and precise feeding of paint through the coordinated work of components such as weighing sensors, scales, weighing instruments, control devices and actuators. This device has the advantages of simple structure, easy operation and low cost. It is suitable for the feeding and proportioning of single raw materials and has been widely used in small and medium-sized paint production enterprises. The process of using an automatic weighing and proportioning device is as follows: when the raw materials are placed on the scale, pressure acts on the weighing sensor to cause it to deform. The resistance strain gauge inside the sensor will produce a change in resistance, and then this change is converted into an electrical signal output. After being processed by the amplification circuit and analog-to-digital converter, the electrical signal is converted into a digital signal and sent to the computer or weighing instrument for processing and display.

[0004] The overall structure of the automatic weighing and proportioning device is relatively simple and easy to install and maintain. However, since all weighing is concentrated on the bracket and its scale body, and all proportioning functions are concentrated on the raw material barrel, once the bracket scale body or related weighing sensor fails, the entire proportioning device may stop working. Since all accessories are assembled as a whole, there is no space for convenient maintenance. It is necessary to disassemble the raw material barrel, the bracket and its scale body, etc., and increase the maintenance space by disassembling the entire device for maintenance; when the bracket of the automatic weighing and proportioning device and the weighing sensor on its scale body fail, there is a problem in the design that the device bracket and the raw material barrel are an integral combination and the position of the bracket and the raw material barrel cannot be adjusted to increase the maintenance space. For this reason, the present application proposes a proportioning device for paint production. Utility Model Content
