Description

Technical Field

[0001] This utility model relates to a noise control device for blowing glass bottles, belonging to the field of noise control equipment. Background Technology

[0002] The existing blow molding machine consists of a mold base and a mold cap. The mold base is split for easy bottle removal, while the mold cap is a single unit fixed to the gas supply pipe. During bottle making, the mold cap, along with the gas supply pipe, is lifted a short distance by an upward and downward sliding device. Molten glass in a high-temperature state flows into the mold base. Then, the mold cap descends and presses against the mold base. The stationary gas supply valve then activates, and compressed air from the gas supply valve, gas supply pipe, and rubber hose ⑤ forces the molten glass into shape. After a few seconds, the mold cap lifts, and the compressed air is discharged at high speed into the atmosphere from the gap between the mold body and the mold cap, generating noise with a sound pressure level exceeding 90 dB(A). Furthermore, a single blow molding machine has 16 blow molding units, resulting in frequent noise generation, and workers are exposed to noise hazards while working next to the machine. Utility Model Content

[0003] The technical problem to be solved by this invention is that the compressed air in existing blow molding processes is discharged into the atmosphere at high speed from the gap between the mold body and the mold cap, resulting in high noise.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a noise control device for blowing glass bottles, including a silencer, an exhaust pipe and a connecting pipe. One end of the connecting pipe is connected to an air supply hose and the other end is connected to an air supply valve. One end of the exhaust pipe passes through the side wall of the connecting pipe and is sealed to the connecting pipe. The other end is provided with an exhaust valve, and the outlet of the exhaust valve is connected to the inlet of the silencer.

[0005] The exhaust valve in the above-mentioned device is a solenoid valve.

[0006] In the above-mentioned device, the connecting pipe and the exhaust pipe are connected to form a T-shaped three-way pipe structure.

[0007] Furthermore, the connection between the connecting pipe and the exhaust pipe in the above-mentioned device is welded and fixed.

[0008] In the above-mentioned device, the exhaust valve is threadedly connected to the end of the exhaust pipe and the inlet of the muffler.

[0009] The silencer in the above device is a hollow bottle-shaped structure with several through holes on its side wall.

[0010] Furthermore, the silencer in the above-mentioned device includes a base plate, a top plate, a fixing ring, and a connecting column. The base plate and the top plate are arranged in parallel. There is at least one fixing ring, which is arranged between the base plate and the top plate. The base plate, the top plate, and the fixing ring are connected by the connecting column. An external threaded pipe is provided in the middle of the top plate.

[0011] Furthermore, the connecting columns in the above-mentioned device are 2 to 6, and are spaced apart circumferentially.

[0012] Furthermore, the connecting columns in the above-mentioned device are 3 to 4.

[0013] In the above-mentioned device, the connecting pipe and the air supply hose are connected by a clamp.

[0014] The beneficial effects of this invention are: the device has a simple structure, is inexpensive to manufacture, and is safe and stable. This device effectively moves the bottle-blowing noise generated by the compressed air exhaust from between the mold base and the mold cap to the exhaust pipe. Simultaneously, a silencer is installed at the end of the exhaust pipe to reduce exhaust noise, without affecting the other operating procedures of the bottle-making machine.

One end of the exhaust pipe 1 is inserted into the side wall of the connecting pipe 8 and sealed to the connecting pipe 8, while the other end is equipped with an exhaust valve 2. The outlet of the exhaust valve 2 is connected to the inlet of the silencer 3. Those skilled in the art will understand that this device moves the compressed air discharge port originally located between the mold base 7 and the mold cover 6 to the exhaust pipe 1, effectively eliminating noise hazards to workers in the worker's work area. Simultaneously, the silencer 3 further reduces noise. Specifically, one end of the connecting pipe 8 is connected to the air supply hose 5, and the other end is connected to the air supply valve 4. Simultaneously, one end of the exhaust pipe 1 is inserted into the side wall of the connecting pipe 8 and sealed to the connecting pipe 8, while the other end is equipped with an exhaust valve 2. This forms a three-way pipe structure between the connecting pipe 8 and the exhaust pipe 1, facilitating connection to the air supply valve 4 and the exhaust valve 2.
