Manufacturing method of high-air-tightness adjustable silencer manufacturing device

1. This utility model relates to the field of muffler manufacturing, in particular to a high-airtightness adjustable muffler manufacturing device.

Background technique:

2. With people's pursuit of living and working environment, the demand for noise cancellation in the working environment is also increasing, and mufflers can be roughly divided into resistive mufflers, resistant mufflers, and impedance composite mufflers There are six types of silencer, micro-perforated plate silencer, small hole silencer and active silencer.

3. The Chinese patent with application number cn202021925582.1 published a resistive ventilation muffler using universal muffler components, including a protective shell, a first muffler component, a second muffler component and a muffler cooling device, the first The muffler assembly includes a cylinder, a muffler, a shaft core, a bearing, a spoke, and a dust screen. The muffler is connected to the shaft and can rotate autonomously under the action of airflow. The spokes are located on the top of the cylinder and can be fixed. A bearing, the shaft core is rotatably connected with the bearing, the second muffler assembly includes a box body, a muffler sheet, a fixed block and a fixed plate, and the muffler sheet is connected to the box body through the fixed plate and the fixed block. The muffler cooling device includes a water inlet pipe, a water outlet pipe, a cooling water pipe and a water tank, the cooling water pipe is connected to the water through the water inlet pipe and the water outlet pipe, the protective casing is located outside the cooling water pipe, and the water tank is divided into a cold water part and a hot water part , The returned hot water is output through the pipeline for daily needs.

4. However, the internal dimensions of the existing resistive muffler cannot be changed arbitrarily during processing, so when the sound-absorbing sheet is nailed, the parts in contact with the air flow are all nailed with lacquer foam, and the rest are nailed with shoe nails. When nailing, you need to add a layer of gasket to the bubble nail. This process requires manual operation, which leads to manual fixation by hand after installation, and then the nail bubble nail operation. If the operation is improper, it may cause the bubble nail to be nailed. Into the human hands, resulting in construction safety accidents, and at the same time the manual fixing of the gasket is not convenient, which affects the processing efficiency.
