Hot-drying stress removal equipment

Abstract

The invention discloses hot-drying stress removal equipment which comprises a thermal insulation box body, a conveying system and a heating air-supply system. The conveying system is arranged inside the thermal insulation box body. The conveying system contains a conveyor belt used for bearing and conveying workpieces. The heating air-supply system comprises a thermal insulation cover fixed inside the thermal insulation box body. The thermal insulation cover is disposed above the conveyor belt. A position regulation device used for regulating distance between a workpiece and the heating air-supply system is mounted between the thermal insulation cover and the conveyor belt. With the arrangement of the conveying system, the heating air-supply system and a temperature control device, multiple dirt filtrating screens can be conveyed and heated simultaneously, so as to enhance production efficiency of products. In addition, each dirt filtrating screen is uniformly heated. Thus, concentrated stress of the dirt filtrating screens can be effectively removed, the structure of each dirt filtrating screen is remained flat, product quality is effectively raised, rejection rate is reduced, and economic benefit is better.

Description

technical field [0001] The invention relates to the field of heat drying equipment, and more specifically relates to a heat drying stress relief equipment. Background technique [0002] When the material cannot be displaced under the action of external force, its geometric shape and size will change, and this deformation is called strain; The concentration of internal force at a point is called stress. The product of stress and micro-area is the internal force, or when the object is deformed due to external factors (force, humidity change, etc.), the internal force that interacts between the various parts of the object is generated to resist the effect of this external factor, and try to make it The object returns from its deformed position to its pre-deformed position. [0003] The dust filter structure includes a filter net and a supporting frame formed on the filter net by injection molding. As a component for filtering dust and protecting the core, the dust filter net ...

AI Technical Summary

Problems solved by technology

However, at this stage, there is no good solution to the mesh deformation or mesh relaxation of the dust filter. If a hair dryer is used to manually heat a single piece of dust filter to remove stress, not only the efficiency is low, but the dust filter is heated unevenly. High scrap rate, resulting in increased costs and waste of resources
