Description

Technical Field

[0001] This application relates to the field of single-fluid pump technology, and in particular to a noise reduction device for an air compressor. Background Technology

[0002] Air compressors play a crucial role in the production of liquor bottle caps, primarily in the following stages: Bottle cap injection molding: Compressed air drives pneumatic actuators to control the mold opening and closing and ejection mechanisms, ensuring injection precision. Pneumatic demolding: High-pressure gas (typically 0.6-0.8 MPa) assists in rapid demolding, reducing product deformation. Bottle cap pressing and sealing: The air compressor provides power to the automatic capping machine, achieving a tight seal between the bottle cap and the bottle neck. Sealing performance testing: Compressed air is injected into the bottle and pressurized (0.2-0.3 MPa), and sealing performance is tested by pressure decay. Cleaning and surface treatment: Residues are blown away; Printing and coding assistance: Compressed air drives the coding equipment to ensure clear markings on the bottle cap surface. Automated transfer: Bottle caps are transferred between workstations via airflow pipelines (negative or positive pressure systems). An air compressor is a device used to compress gas, converting the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy. Noise reduction is necessary during air compressor operation.

[0007] The beneficial effects of the air compressor noise reduction device described in this invention are as follows: Because of the opening mechanism, the opening plate is opened by four rotating shafts, which can expel the hot air inside the installation box. Because of the integrated heat dissipation mechanism, water from the storage tank is pumped to the outlet pipe, enters the surrounding pipe, and then circulates back to the storage tank, forming a closed cooling loop. The water flow carries away heat from the air compressor, achieving basic heat dissipation. When a certain level is reached, the sensor automatically activates, simultaneously switching between water-cooling and air-cooling modes. In water-cooling mode, the entire unit is sealed, providing noise isolation. In dual-mode, perforated sound-absorbing panels, which not only have excellent air permeability and heat dissipation but also effectively absorb and disperse noise due to their unique perforated structure, further enhance noise reduction. The combination of the perforated sound-absorbing panels and the air-cooling system allows the device to maintain low noise levels while achieving efficient heat dissipation. The sound level also provides a good noise reduction effect, providing users with a quieter and more comfortable working environment. The dual-mode working together further enhances the heat dissipation effect. In water cooling mode, the water flow accelerates in the surrounding pipe, taking away more heat and allowing the temperature inside the air compressor to drop quickly. When the wind power mode is activated, the fan speed at the vent increases, and a large amount of cold air is drawn into the device, making full contact with the air compressor surface, quickly taking away the heat and expelling it to the outside. At the same time, the system automatically adjusts the power of the water pump and fan the moment the sensor activates the dual mode to achieve the best heat dissipation combination. The water pump will precisely control the speed and flow rate of the water according to the specific temperature value to ensure the maximum efficiency of water cooling. Because of the second heat dissipation mechanism, the heat generated by the noise reduction device during operation can be dissipated in time, avoiding equipment failure or performance degradation caused by excessive temperature, thus ensuring the stable operation of the air compressor. The heat dissipation rods on both sides drive the fan blades to rotate at high speed, forming a convective airflow field, accelerating the discharge of hot air inside the mounting box, and achieving forced heat dissipation. Because of the cleaning mechanism, the cleaning roller rolls on the surface of the filter screen under the action of the hydraulic cylinder, removing the dust and impurities attached to the filter screen and keeping the filter screen clean, thereby improving the operating efficiency of the air compressor and the air quality. At the same time, the design of the cleaning shell can effectively protect the cleaning roller, prevent it from being damaged during the cleaning process, and extend the service life of the cleaning device. Because of the material receiving mechanism, when the drawer moves to the front, it can be automatically pulled out to empty the dust and impurities inside, and then cleaned. This improves work efficiency and effectively avoids secondary pollution from dust and impurities. At the same time, the cooperation between the drive motor and the screw enables the drawer to move smoothly and automatically, further improving the automation level of the entire air compressor noise reduction device. Because of the energy-saving mechanism, when the air compressor is running, the vibration is transmitted to the spring plate through the damping plate. When the vibration amplitude exceeds the set threshold, the pressing plate deforms and presses down with the spring plate, contacts the pressing plate and triggers the mechanical linkage. The pressing plate drives the slider to slide vertically down the guide column through the rigid connecting rod, compresses the spring and drives the slot to move synchronously. Because of the shock absorption and buffer mechanism, the shock-absorbing plate can be automatically vibrated by the control button and the vibration motor, which are connected to the battery and the corresponding control button by wires respectively.

[0008] This invention can reduce noise in air compressors while also providing heat dissipation. During operation, it can also reduce vibration and achieve energy saving, thus improving the overall performance. Attached Figure Description

[0023] In this invention, when cooling the air compressor 8 is required, the water pump is activated. Water from the storage tank 5 is pumped to the outlet pipe 6, enters the surrounding pipe 10, and then circulates back to the storage tank 5, forming a closed cooling loop. The water flow carries away the heat inside the air compressor, achieving basic heat dissipation. The water cooling circulation lowers the core temperature of the air compressor, while hot air is exhausted through the vents, forming an internal and external circulation cooling system that significantly improves heat dissipation efficiency. When the temperature of the cooling air reaches a preset threshold, the sensor automatically activates both the water cooling mode and the fan mode simultaneously. The dual modes work together to further enhance the heat dissipation effect. In water cooling mode, the water flow accelerates in the surrounding pipe, carrying away more heat and causing the temperature inside the air compressor to drop rapidly. When the fan mode is activated, the fan speed at the vents increases, drawing a large amount of cool air into the device and ensuring full contact with the air compressor surface. The system rapidly removes heat and expels it to the outside. Simultaneously, the moment the sensor activates the dual-mode, the system automatically adjusts the power of the water pump and fan to achieve the optimal cooling combination. The water pump precisely controls the water flow rate and speed based on the specific temperature value to maximize the water cooling effect. The fan also adjusts its speed according to temperature changes, ensuring efficient airflow. Under the combined effect of the dual modes, even when the noise reduction device is operating under high load, it maintains a stable low-temperature environment, effectively preventing equipment damage and performance degradation caused by excessive temperature. Moreover, this intelligent cooling mode switching method greatly improves the automation level of the device, reduces manual intervention, lowers operating costs and maintenance difficulty, and allows the air compressor to operate more stably and efficiently. In water-cooled mode, the entire unit is sealed, providing noise isolation; in dual-mode, perforated sound-absorbing panels... The perforated sound-absorbing panel not only has good air permeability and heat dissipation, but its unique perforated structure also effectively absorbs and disperses noise, further enhancing the noise reduction effect. The combination of the perforated sound-absorbing panel and the air-cooling system allows the device to maintain a low noise level while achieving efficient heat dissipation, providing a quieter and more comfortable working environment for users. When it is necessary to open the four through holes 12 for heat dissipation, the drive motor is started. Its output shaft drives one of the rotating shafts 13 to rotate, which in turn drives one of the gears 14, which in turn drives three other gears 14. The four rotating shafts 13 then open the opening plate 15, allowing the contents of the mounting box 1 to be opened. The hot air is discharged. Simultaneously, when it is necessary to open the arc-shaped plate 23 on the surrounding tube 10, one of the rotating shafts 13 drives the first sprocket 18 to rotate, which in turn drives the second sprocket 20 to rotate via chain 19. The second sprocket 20 simultaneously drives the rotating rod 21, the first bevel gear 25, the second bevel gear 28, the rotating rod 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 arc-shaped plate 23 to open, exposing the surface of the surrounding tube 10 and enhancing air convection cooling efficiency. When it is necessary to cool the air inside the mounting box 1, the drive motor 3 is started, and its output shaft drives one of the cooling rods 30 to rotate. One of the cooling rods 30 drives one of the fourth bevel gears 32 to rotate. The fourth bevel gear 32 drives one of the fifth bevel gears 34 to rotate, which in turn drives one of the second heat sink rods 35 to rotate. The second heat sink rod 35 then drives one of the third sprockets 36 to rotate, which in turn drives another third sprocket 36 via a chain 37. This third sprocket 36 then drives another second heat sink rod 35 to rotate, which in turn drives another fifth bevel gear 34 to rotate. This fifth bevel gear 34 then drives another fourth bevel gear 32 to rotate, which in turn drives another first heat sink rod 30 to rotate. The two first heat sink rods 30 drive the two fan blades 31 to rotate, generating airflow during rotation. The air flows out through the heat dissipation holes on the mounting box 1, thereby dissipating heat from the air inside the mounting box 1. The heat generated by the noise reduction device during operation can be dissipated in time, avoiding equipment failure or performance degradation caused by excessive temperature, thus ensuring the stable operation of the air compressor. The heat dissipation rods 30 on both sides drive the fan blades 31 to rotate at high speed, forming a convective airflow field, accelerating the discharge of hot air inside the mounting box 1, and achieving forced heat dissipation. When it is necessary to dampen the air compressor 8, the vibration generated by the air compressor 8 during operation is transmitted to the damping plate 7 through a rigid connection. The damping plate 7 acts as a vibration carrier, transmitting energy downward to the spring plate 38. It adopts a high-strength alloy steel helical spring, which has a large deformation range and high load-bearing capacity, and absorbs high-frequency vibration energy through elastic deformation.During operation, the air compressor 8 drives the damping plate 7 to vibrate, compressing the spring plate 38. A damper is installed on the top of the spring plate 38, effectively reducing the vibration amplitude and resonance amplitude during operation, preventing structural damage caused by excessive dynamic stress, thus ensuring the stability and durability of the equipment. When automatic vibration of the damping plate 7 is required, it can be achieved via control button 57 and vibration motor 59, which are connected to a battery and the corresponding control button 57 respectively via wires. When energy saving of the sensor is required, during the compression of the spring plate 38 during operation of the air compressor 8, the pressure plate will contact the sensor. When the press plate 60 moves downward, it simultaneously drives the slider 41, the slot 44, the spring 43, and the second quartz stone 42 downward. The second quartz stone 42 moves downward and comes into contact with the first quartz stone 40. When the two quartz stones are squeezed, a voltage difference is generated on their surfaces. If the two materials are connected by a wire, electrons will flow to form a current, which is stored in the storage tank and can be used to operate the noise reduction device later. When the air compressor 8 is running, the vibration is transmitted to the spring plate 38 through the damping plate 7. When the vibration amplitude exceeds the set threshold, the press plate deforms and presses down with the spring plate 38, contacting the press plate 60 and triggering the mechanical linkage. The press plate 60 drives the slider 41 to slide vertically down along the guide column through the rigid connecting rod, compressing the spring 43. This causes the slot 44 to move synchronously. When cleaning of the filter screen 3 is required, hydraulic cylinder 46 is activated, and its output shaft pushes the cleaning plate 45 forward. When it reaches the appropriate position, hydraulic cylinder 47 is activated, and its output shaft pushes the cleaning shell 48 forward. During this movement, the cleaning roller rolls on the surface of the filter screen 3 under the action of hydraulic cylinder 47, removing dust and impurities adhering to the filter screen and keeping it clean. This improves the operating efficiency of the air compressor and the air quality. Simultaneously, the design of the cleaning shell 48 effectively protects the cleaning roller, preventing damage during cleaning and extending the service life of the cleaning device. During the cleaning process, it can effectively remove dust and impurities. Dust is collected by starting drive motor 51, whose output shaft drives screw 52. As screw 52 rotates, it drives moving block 53 forward, which in turn drives drawer 49 forward. During cleaning, drawer 49 has an opening at the front end to facilitate the collection of dust and impurities. When drawer 49 moves to the front, it can be automatically pulled out to empty the dust and impurities inside for cleaning, which improves work efficiency and effectively avoids secondary pollution from dust and impurities. At the same time, the coordinated use of drive motor 51 and screw 52 enables the smooth and automatic movement of drawer 49, further enhancing the automation level of the entire air compressor noise reduction device.

[0024] Example 2

[0025] The difference between this embodiment and Embodiment 1 is that four pads are fixedly installed at the bottom of the mounting box 1. All four pads are made of rubber, which has good elasticity and wear resistance. This can effectively reduce the vibration and noise generated by the air compressor noise reduction device during operation, improve the stability and service life of the entire device, and the design of the pads can also increase the friction between the mounting box and the ground, prevent the device from sliding or shifting during use, and ensure the safety and reliability of the device.
