Integrated miniature multi-hole air knife

Abstract

The invention discloses an integrated miniature multi-hole air knife. The integrated miniature multi-hole air knife comprises a shell body, an air inlet pipe, a sealing rubber strip, a mounting and fixing device, a distance adjusting device, a connecting rod, a fixing sleeve, air outlets, first telescopic springs, sliding grooves, elastic cleaning strips, a first sliding block, a first fixing rodand bristles, wherein the center of one side of the shell body is provided with the air inlet pipe, the sealing rubber strip is fixed between the air inlet pipe and the shell body through adhesion, the air outlets are uniformly formed in the center of the other side of the shell body, the sliding grooves are correspondingly formed in the two sides of the shell body, the inner portions of the sliding grooves are provided with first sliding blocks, the first telescopic springs are connected between one sides of the first sliding blocks and the inner walls of one sides of the corresponding sliding grooves, the sides, close to the air outlets, of the first sliding blocks are movably connected with the elastic cleaning strips through hinges, and the bristles are distributed uniformly at the inner sides of the elastic cleaning strips. The integrated miniature multi-hole air knife has the advantages that installation and fixing are convenient, smudginess is convenient to clean, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of panels, PCBs, and semiconductor wet process equipment, in particular to integrally formed miniature porous air knives. Background technique [0002] Air knives are often used in the industrial field to remove water and dust by blowing, such as blowing off dust and moisture on the surface of steel plates, aluminum alloy profiles, beverage bottles and packaging cans, blowing off impurities, dust and residual liquid on the surface of products, and cleaning Conveyor belt cleaning, etc. The air knife can be driven by a vortex fan or a high-pressure centrifugal fan instead of high-energy compressed air. It blows out the gas at a high speed with a thin sheet with a thickness of only 0.05 mm. Through the Coanda effect principle and the special geometric shape of the air knife, this sheet The air curtain can gradually form a thin high-strength, high-flow impingement air curtain. Air knives can be divided into tw...

AI Technical Summary

Problems solved by technology

However, the air knife of this design is made in a combined way, that is, the volume of the perforated plate, the substrate water storage structure and the supporting skeleton structure is huge, and the assembly space required for the overall assembly is relatively large

At the same time, there are also problems of inconvenient installation and fixation, inconvenient cleaning and dirt, and weak practicability. In daily use, it is difficult to clamp for different heights of the clamping position, and then it is necessary to use the help of external parts to complete the reservation. The clip operation makes the installation space further enlarged, and it is easy to fall off due to the influence of external force when the installation is fixed. its cleaning operation
