Novel paint drying device

Abstract

The invention discloses a novel paint drying device, which comprises an oven, a turntable motor, a mechanical arm motor, a main circuit, an alternating current control circuit and a direct current control circuit. The oven has an openable window for taking and placing a workpiece; a bracket, which is divided into a plurality of equal sections and rotationally hold the workpiece, is arranged at the bottom of the cavity in the oven, and the plurality of brackets form a turntable; heating tubes are uniformly distributed on the two sides of the cavity; the cavity wall of the cavity is a thermal-insulation layer; and a mechanical arm for taking and placing the workpiece is arranged on the opposite side of the window. A plurality of groups of heating tubes and frequency converters are arranged in the main circuit, and a programmable controller is arranged in the direct current control circuit. In the invention, the heat loss is small, the energy-saving effect is obvious, the automation degree is high, the temperature control is accurate, the baking time is accurate, labor resources are saved, product quality is guaranteed, economic benefit is great, delivery can be made quantitatively on time, lean product requirement is met, production arrangement is made easier, volume is small and space is saved.

Description

technical field [0001] The invention relates to a novel paint drying device for drying the paint surface after spraying paint on the surface during the production process of nonferrous metal die-casting products. Background technique [0002] In the production process of non-ferrous metal die-casting products, painting the surface of die-casting products is a relatively common surface treatment method, and drying the paint has always been a very energy-consuming production process. There are many disadvantages in the current general-purpose drying equipment, such as: high energy consumption, excessive internal air flow that pollutes the paint causing many defective products, uneven temperature control causing overheating of the paint surface, etc. There are two main types of paint drying equipment commonly used today and the corresponding disadvantages are as follows: [0003] 1. Drying wire: The drying wire must be able to meet the requirements of mass production and lean ...

AI Technical Summary

Problems solved by technology

However, the energy consumption is huge, and the open air circulation is easy to pollute the paint surface, and the defective rate is high;

[0004] 2. Drying oven: The oven has less capacity and has intermittent time intervals, which cannot meet the requirements of lean production

The drying box also has uneven temperature control, which is likely to cause overheating of the paint surface and cause defective products;

[0005] The above two types of equipment must be connected to or placed in the clean room, which will cause pollution in the clean room
