Description

[Technical field]

[0001] The invention relates to the technical field of bottle blowing machines, and in particular to an internal cleaning process of an air storage cylinder of a bottle blowing machine. [Background technology]

[0002] Blow Molding Machine refers to a machine that blows bottles. The most common explanation is that it is a machine that can blow plastic particles (softened into liquid) or finished bottle embryos into bottles through certain process means. Blow molding machines are convenient and fast, with a large molding volume. After their appearance, they replaced most manual bottle blowing and were adopted by most beverage companies. The air cylinder of the blow molding machine is used to store the gas compressed by the air compressor (air pump). In order to reduce the manufacturing cost of the blow molding machine, the high-pressure and low-pressure air cylinders of the blow molding machine are currently made of carbon steel. After welding, the exterior surface is sprayed with paint for rust prevention, but the interior of the air cylinder cannot be polished and cleaned, and the welding slag at the welding point cannot be effectively polished and removed, so the quality of the air cylinder cannot be guaranteed, which directly affects the quality of the blow molding bottle.

[0003] During the bottle blowing process, the bottle blowing machine finds welding slag, iron filings, etc. inside the bottle, which is usually related to the fact that the internal cleaning of the gas cylinder inside the bottle blowing machine is not done well. These foreign objects and iron filings are directly blown into the bottle during high-pressure blowing. For example, the prior art CN220169156U is a horizontal gas tank that is easy to clean, which relates to the technical field of gas tanks, including a gas tank body, which is connected to a tank cover by threads, and a cleaning mechanism is provided on one side of the tank cover. The cleaning mechanism includes a low-speed motor, a shaft frame and a brush, and a bearing is provided at one end of the shaft frame. A brush is installed on one side of the shaft frame, and one side of the brush fits the inner wall of the gas tank body. This prior art uses a brush to clean the inner wall of the gas tank, but the brush is a soft material, and the cleaning effect is poor when facing foreign objects such as welding slag and iron filings that are strongly attached to the inner wall of the tank body.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Summary of the invention]
