Description

TECHNICAL FIELD

[0001] The application relates to the technical field of single-sex fluid pumps, in particular to an air compressor noise reduction device. BACKGROUND

[0002] The air compressor plays a key role in the production of white wine bottle caps and is mainly applied to the following links: bottle cap injection molding: compressed air drives pneumatic actuators to control the opening and closing of the mold and the ejection mechanism, ensuring the precision of bottle cap injection. Pneumatic demolding: high-pressure gas (usually 0.6-0.8 MPa) assists in rapid demolding to reduce product deformation. Bottle cap compression and sealing: the air compressor provides power for the automatic capping machine to achieve tight compression of the bottle cap and the bottle opening. Sealing detection: compressed air is injected into the bottle to pressurize (0.2-0.3 MPa), and the sealing performance is detected by pressure decay. Cleaning and surface treatment: blowing residual materials; printing and code spraying assistance: compressed air drives code spraying equipment to ensure clear bottle cap surface markings. Automated transmission: bottle caps are transferred between stations through air conveying pipelines (negative or positive pressure systems). The air compressor is a device used to compress gas, which converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. The air compressor needs to be noise-reduced during operation.

[0016] The beneficial effects of the air compressor noise reduction device described in this invention are as follows:

[0017] Because of the opening mechanism, the opening plate is opened by four rotating shafts, which can expel the hot air inside the installation box.

[0018] Due to the setting of the heat dissipation mechanism one, the water source in the storage tank is transported to the water outlet pipe by the water pump, enters the circulating pipe and returns to the storage tank, forming a closed cooling loop, which removes the heat inside the air compressor through the water flow, realizes the basic heat dissipation function, and reaches a certain degree, the inductor automatically opens the water cooling mode and the wind energy mode, in the water cooling mode, the whole is closed, which plays a noise isolation effect; in the double mode, through the perforated sound absorption plate, the perforated sound absorption plate not only has good air permeability, but also can achieve good heat dissipation effect, and its unique perforated structure can effectively absorb and disperse noise, further improve the noise reduction effect, the combination of the perforated sound absorption plate and the air cooling system can not only maintain a low noise level while efficiently dissipating heat, but also can achieve good noise reduction effect, providing a more quiet and comfortable working environment for users, and the double mode works together to further enhance the heat dissipation effect, in the water cooling mode, the water flow accelerates in the circulating pipe, taking away more heat, so that the temperature inside the air compressor can quickly drop, and after the wind energy mode is started, the fan speed at the ventilation opening is accelerated, a large amount of cold air is sucked into the device, fully contacts the surface of the air compressor, quickly takes away the heat and discharges it to the outside, at the same time, the system will automatically adjust the power of the water pump and the fan to achieve the best heat dissipation combination when the inductor opens the double mode, the water pump will accurately control the speed and flow of the water flow according to the specific value of the temperature, to ensure the maximum rate of water cooling effect;

[0019] Due to the setting of the heat dissipation mechanism two, the heat generated by the noise reduction device during work can be dissipated in time, avoiding equipment failure or performance decline caused by high temperature, so as to ensure the stable operation of the air compressor, the two side heat dissipation rods one drive the fan blades to rotate at high speed, forming a convection wind field, accelerating the exhaust of hot air inside the installation box, realizing forced heat dissipation;

[0020] Due to the setting of the cleaning mechanism, the cleaning roller will roll on the surface of the filter screen under the action of the hydraulic cylinder two, removing the dust and impurities attached to the filter screen, keeping the filter screen clean, thereby improving the operation efficiency and air quality of the air compressor, at the same time, the design of the cleaning shell can effectively protect the cleaning roller from being damaged during cleaning, prolonging the service life of the cleaning device;

[0063] In the application, when the air compressor 8 needs to be cooled, the water pump is started, the water source in the storage tank 5 is delivered to the water outlet pipe 6 through the water pump, and then flows back to the storage tank 5 after circulating in the surrounding pipe 10, forming a closed cooling loop. The water flow carries away the heat inside the air compressor, realizes the basic cooling function, reduces the core temperature of the air compressor through water cooling circulation, and at the same time, the hot air is discharged through the air vent, forming an internal and external circulation cooling system, which significantly improves the cooling efficiency. When the temperature of the cooling air reaches the preset threshold value, the inductor automatically opens the water cooling mode and the wind energy mode, and the double modes work together to further enhance the cooling effect. In the water cooling mode, the water flow accelerates in the surrounding pipe, carrying away more heat, so that the temperature inside the air compressor can quickly drop. After the wind energy mode is started, the fan speed at the air vent is accelerated, a large amount of cold air is sucked into the device, fully contacts the surface of the air compressor, quickly carries away the heat and discharges it to the outside. At the same time, the inductor opens the double mode, the system automatically adjusts the power of the water pump and the fan to achieve the best cooling combination. The water pump accurately controls the speed and flow of the water flow according to the specific value of the temperature, ensures the maximization of the water cooling effect, and the fan also adjusts the wind speed according to the temperature change, so that the wind energy can play an efficient role. Under the joint action of the double mode, even if the noise reduction device is in a high-load running state, it can also maintain a stable low-temperature environment, effectively avoiding the problems of equipment damage and performance decline caused by high temperature. Moreover, this intelligent cooling mode switching method greatly improves the automation degree of the device, reduces manual intervention, reduces use cost and maintenance difficulty, and makes the air compressor run more stably and efficiently. In the water cooling mode, the whole is closed, and the noise isolation effect is achieved; in the double mode, the perforated sound absorption plate,

[0064] The perforated sound absorption plate not only has good air permeability, but also can achieve good heat dissipation effect. The unique perforated structure can effectively absorb and disperse noise, further improve the noise reduction effect, and the combination of the perforated sound absorption plate and the air cooling system can maintain a low noise level while achieving efficient heat dissipation, and can also achieve good noise reduction effect, providing a more quiet and comfortable working environment for users. When the four through holes 12 need to be opened for heat dissipation, the drive motor one is started, the output shaft drives one of the shafts 13 to rotate, one of the shafts 13 drives one of the gears one 14 to rotate, and three gears one 14 are driven by one of the gears one 14 to rotate. Four shafts 13 drive the opening plate 15 to open, which can exhaust the hot air inside the installation box 1. At the same time, when the arc-shaped plate 23 on the surrounding pipe 10 needs to be opened, one of the shafts 13 drives the first sprocket 18 to rotate, and the chain one 19 drives the second sprocket 20 to rotate, which in turn drives the rotating rod one 21, the first bevel gear 25, the second bevel gear 28, the rotating rod two 29, the third bevel gear 26, the rotating shaft 27 and the arc-shaped plate 23 to rotate together. The rotating shaft 27 controls the opening of the arc-shaped plate 23, exposing the surface of the surrounding pipe 10, and enhancing the air convection heat dissipation efficiency. When the air inside the installation box 1 needs to be cooled, the drive motor three is started, the output shaft drives one of the heat dissipation rods one 30 to rotate, one of the heat dissipation rods one 30 drives one of the fourth bevel gears 32 to rotate, one of the fourth bevel gears 32 drives one of the fifth bevel gears 34 to rotate, one of the fifth bevel gears 34 drives one of the heat dissipation rods two 35 to rotate, one of the heat dissipation rods two 35 drives one of the third sprockets 36 to rotate, and the chain two 37 drives the other third sprocket 36 to rotate. The other third sprocket 36 drives the other heat dissipation rod two 35 to rotate, the other heat dissipation rod two 35 drives the other fifth bevel gear 34 to rotate, the other fifth bevel gear 34 drives the other fourth bevel gear 32 to rotate, the other fourth bevel gear 32 drives the other heat dissipation rod one 30 to rotate, two heat dissipation rods one 30 drive two fan blades 31 to rotate, and two fan blades 31 generate air flow during rotation. The air flow flows out through the heat dissipation holes on the installation box 1, thereby achieving air cooling inside the installation box 1. The heat generated by the noise reduction device during operation can be dissipated in time, avoiding equipment failure or performance degradation due to high temperature, thereby ensuring the stable operation of the air compressor. The two heat dissipation rods one 30 drive the fan blades 31 to rotate at high speed, forming a convection wind field, accelerating the discharge of hot air inside the installation box 1, and achieving forced cooling. When the air compressor 8 needs to be cushioned, the vibration generated by the air compressor 8 during operation is transmitted to the damping plate 7 through rigid connection, and the damping plate 7 acts as a vibration carrier to conduct energy downward to the spring plate 38. The high-strength alloy steel spiral spring has large deformation and high bearing capacity, and can absorb high-frequency vibration energy through elastic deformation.The air compressor 8 will drive the damping plate 7 to vibrate during operation, which will compress the spring plate 38. The top of the spring plate 38 is provided with a damper, which can effectively reduce the vibration amplitude and resonance amplitude during operation, prevent structural damage caused by excessive dynamic stress, and ensure the stability and durability of the equipment. When the damping plate 7 needs to vibrate automatically, the control button 57 and the vibration motor 59 are connected with the battery and the corresponding control button 57 through wires, respectively, which can realize the automatic vibration function of the damping plate 7. When the sensor needs to be energy-saving, the pressing plate will contact the pressing plate 60 during the compression process of the spring plate 38 during the operation of the air compressor 8. When the pressing plate 60 moves downward, it will simultaneously drive the sliding block 41, the clamping groove 44, the spring 43 and the quartz stone two 42 to move downward. The quartz stone two 42 moves downward and contacts the quartz stone one 40. When the two quartz stones are pressed, a voltage difference will be generated on the surface. If the two materials are connected by wires, electrons will flow to form an electric current. The current is stored in the storage box, which can operate the noise reduction device in the subsequent process. When the air compressor 8 operates, the vibration is transmitted to the spring plate 38 through the damping plate 7. When the vibration amplitude exceeds the set threshold, the pressing plate deforms and presses down with the spring plate 38, contacts the pressing plate 60 and triggers the mechanical linkage. The pressing plate 60 drives the sliding block 41 to slide vertically along the guide column through the rigid connecting rod, compresses the spring 43 and drives the clamping groove 44 to displace synchronously. When the surface of the filter screen 3 needs to be cleaned, the hydraulic cylinder one 46 is started, and its output shaft pushes the cleaning plate 45 to move forward. When it moves to the appropriate position, the hydraulic cylinder two 47 is started, and its output shaft pushes the cleaning shell 48 to move forward. During the movement, the cleaning roller rolls on the surface of the filter screen 3 under the action of the hydraulic cylinder two 47, removes the dust and impurities attached to the filter screen, keeps the filter screen clean, and improves the operation efficiency of the air compressor and the air quality. At the same time, the design of the cleaning shell 48 can effectively protect the cleaning roller and avoid damage during cleaning, prolonging the service life of the cleaning device. During cleaning, dust can be collected by starting the drive motor two 51, which drives the screw 52 to rotate. The screw 52 drives the moving block 53 to move forward during rotation. The moving block 53 drives the drawer 49 to move forward at the same time. During cleaning, the front end of the drawer 49 is provided with an opening for the collection of dust and impurities. When the drawer 49 moves to the front end, it can be automatically pulled out to dump the dust and impurities inside, and then cleaned, improving the work efficiency and effectively avoiding secondary pollution of dust and impurities. At the same time, the cooperation of the drive motor two 51 and the screw 52 realizes the stable and automatic movement of the drawer 49, further improving the automation degree of the entire air compressor noise reduction device.
