Abstract

The invention discloses a film coating device, which comprises a bottom plate, a drainage pool and an immersion pool are arranged on the bottom plate, a liquid inlet pipe is arranged at the end of the dipping pool, a filter screen is set inside the liquid inlet pipe, and a filter net is set on the bottom plate. There is a support rod, the end of the support rod is provided with a top plate, the lower end of the top plate is provided with a connecting rod, the lower end of the connecting rod is provided with a guide wheel, the support rod is provided with a traction wheel, and the traction The pulley is docked with the guide wheel, and the traction wheel and the guide wheel are wound with a backguy, one end of the backguy is a free end, and the other end of the backguy is provided with a suction cup, and the suction cup is arranged in the dipping tank. The invention can pour the paste polyvinyl chloride resin liquid into the dipping tank through the liquid inlet pipe, and can place the metal horn shell in the dipping pool, thereby conveniently coating the surface of the metal horn shell, and the coating efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of a coating device, in particular to a coating device. Background technique [0002] The iron shell speaker is a kind of air-cushion horn, so its development history is consistent with the development of the air-cushion horn. Improve the problem of rapid attenuation of low frequency caused by the rigid air of general closed speakers. The dynamic monomer is usually composed of a cone and a voice coil. The edge of the cone is supported by an elastic material, which makes it unable to have a free air vibration frequency. If the air-tight speaker is filled with sound-absorbing materials, the speaker system will generate a vibration frequency higher than that of a single driver. Edgar Villchur installed a monomer with a free air vibration frequency of about 10Hz into a 1.7 cubic foot air-tight speaker. The resonance frequency of the speaker is increased to 43Hz. Since then, the iron-shell speaker in the air-c...
