Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, specifically to a pneumatically driven mechanical transfer device. Background Technology

[0002] Mechanical transfer equipment is a type of mechanical device used for automated handling, transfer, and sorting of materials, widely used in manufacturing, logistics, and warehousing. This type of equipment effectively improves production efficiency, reduces labor costs, and ensures rapid material flow. However, in certain specific working environments, mechanical transfer equipment requires the use of pneumatic motors for drive, to achieve greater flexibility and safety.

[0003] Pneumatic motors use compressed air as a power source and have advantages such as simple structure, high output torque, and smooth operation, making them particularly suitable for use in environments requiring high safety and reliability. The operation of a pneumatic motor requires a stable supply of compressed air, which necessitates the use of an air pump to provide the necessary air source. The air pump compresses air and delivers it to the pneumatic motor, providing power to drive the normal operation of the mechanical transfer equipment.

[0004] The connection between an air pump and a pneumatic motor typically involves pipe connections and interface mating. The air pump delivers compressed air to the air inlet of the pneumatic motor through pipes, usually using quick couplings or threaded connections to ensure the stability and sealing of the air supply.

[0005] In the process of an air pump supplying compressed air to a pneumatic motor, air quality is crucial to ensure the efficient operation of the motor and extend the equipment's lifespan. This necessitates the use of filters to remove impurities from the compressed air. However, current filters on the market are often inconvenient to maintain and replace, potentially affecting the normal operation and maintenance efficiency of the equipment in practical applications. Therefore, we propose an air pump-driven mechanical transfer device. Utility Model Content

[0006] The purpose of this invention is to provide a pneumatically driven mechanical transfer device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pneumatic pump-driven mechanical transfer device includes a U-shaped conveyor frame with a transfer conveyor belt inside. The transfer conveyor belt is used for automated material transfer, improving work efficiency. A pneumatic motor for driving the transfer conveyor belt is located at the front of the U-shaped conveyor frame. The pneumatic motor is powered by compressed air, has explosion-proof characteristics, and is suitable for flammable and explosive environments. A reversing valve is located at the front of the U-shaped conveyor frame. The reversing valve is used to switch the airflow direction to control the forward and reverse rotation of the pneumatic motor. The reversing valve is equipped with a first air guide pipe, a first connecting pipe, and a second connecting pipe. The first connecting pipe and the second connecting pipe are respectively connected to the two air guide ends of the pneumatic motor. The first connecting pipe and the second connecting pipe achieve the adjustment of the pneumatic motor's rotation direction through bidirectional air guidance.

[0009] The bottom of the U-shaped conveyor frame is equipped with a U-shaped bracket, which is used to fix the air compressor pump and filter to ensure stable operation of the equipment. The air compressor pump and filter are mounted on the U-shaped bracket. The air compressor pump is powered by an external power source and generates a high-pressure air source by compressing ambient air to provide power to the system. The filter includes a filter housing. The right side of the filter housing is equipped with an air inlet port, which is used to receive compressed air output from the air compressor pump. The output end of the air compressor pump is connected to the air inlet port through a second air guide pipe. The second air guide pipe ensures that the compressed air enters the filter smoothly for processing. The left side of the filter housing is equipped with an air outlet port, which is connected to the first air guide pipe. The air outlet port delivers the purified clean air to the pneumatic motor.

[0010] The filter box contains, from right to left, a coarse filter plate, a medium-efficiency filter plate, and a fine filter plate. The coarse filter plate is a mesh metal filter used to intercept large particulate pollutants, the medium-efficiency filter plate is a polyester fiber filter used to adsorb medium-sized particles, and the fine filter plate is an activated carbon filter used to remove fine particles to ensure air purity.

[0011] The filter box has an internally threaded fixing tube in the middle of the rear side of the inner wall, which provides a fixing point for the threaded rod and ensures the stable pressing of the cover plate. The filter box has a cover plate in the front side, and a circular mounting hole is opened in the middle of the front side of the cover plate. The circular mounting hole is connected to the threaded rod, which is threaded into the internally threaded fixing tube. A circular pressure plate is provided on the outer wall of the threaded rod near the front end. The circular pressure plate applies pressure by rotating to press the cover plate to prevent air leakage. The front end of the threaded rod is provided with a rotating wheel, which is easy to operate manually to realize the quick opening or locking of the cover plate.

[0012] Preferably, an air collection hood is provided on the left side of the inner wall of the filter box. The air collection hood is connected to the air outlet port. The air collection hood is used to collect the filtered clean air and guide it to the air outlet port. A pressure sensor is provided on the inner wall of the air collection hood. The pressure sensor monitors the air pressure inside the filter box in real time. When the air pressure decreases, the pressure sensor feeds back an electrical signal to the controller for an abnormal warning.

[0013] Preferably, a buzzer is provided on the left side of the filter box, which is powered by an external power source. The buzzer sounds an alarm when the air pressure is abnormal, prompting the staff to clean the coarse filter plate, medium-efficiency filter plate and fine filter plate in time. A controller is provided on the top of the filter box. The buzzer and the pressure sensor are electrically connected to the controller through wires. The controller receives the pressure sensor signal and controls the buzzer to realize the automatic alarm function.

[0014] Preferably, the inner wall of the filter box is provided with three U-shaped positioning grooves. The coarse filter plate, the medium-efficiency filter plate, and the fine filter plate are respectively inserted into the three U-shaped positioning grooves. The U-shaped positioning grooves ensure that the coarse filter plate, the medium-efficiency filter plate, and the fine filter plate are accurately positioned, avoiding displacement that could lead to sealing failure.

[0015] Preferably, a rectangular sealing plate is provided on the rear side of the cover plate. The front sides of the coarse filter plate, medium-efficiency filter plate, and fine filter plate all abut against the rear side of the rectangular sealing plate. The rectangular sealing plate blocks the leakage path of unfiltered air by tightly fitting the front side of the filter. A first frame-shaped rubber gasket is fitted on the outer side of the rectangular sealing plate. The outer side of the first frame-shaped rubber gasket is tightly fitted with the inner wall of the filter box. The first frame-shaped rubber gasket fills the gaps and enhances the side sealing effect of the rectangular sealing plate.

[0016] Preferably, a second frame-shaped rubber pad is provided on the rear side of the cover plate near the outer edge. The rear side of the second frame-shaped rubber pad is in close contact with the front side of the filter box. The second frame-shaped rubber pad provides a secondary seal between the cover plate and the filter box to prevent air leakage.

[0017] Preferably, positioning tubes are provided on the rear side of the inner wall of the filter box and near the four corners. Four positioning rods are arranged in a matrix on the rear side of the rectangular sealing plate. The four positioning rods are respectively inserted into the four positioning tubes. The positioning rods cooperate with the positioning tubes to realize the rapid alignment of the rectangular sealing plate and ensure installation accuracy.

[0018] Preferably, the rear side of the circular pressure plate is provided with sealing rubber, and the rear side of the sealing rubber is in close contact with the front side of the cover plate. The sealing rubber fills the gap between the threaded rod and the cover plate by deforming under pressure, preventing local air leakage.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This air pump-driven mechanical transfer device, through the quick opening and closing design of the threaded rod and the rotating wheel, allows operators to easily remove the cover plate and directly replace the three-stage filter element without the use of additional tools, greatly shortening maintenance time and reducing the impact of equipment downtime on production efficiency. At the same time, the modular plug-in structure of the filter element and the positioning components work together to ensure that the replacement process is accurate and efficient.

[0021] 2. This air pump driven mechanical transfer equipment adopts a combination sealing scheme of rectangular sealing plate and double frame rubber gasket, combined with the structural design of circular pressure plate pressing the sealing rubber, to achieve all-round airtight protection inside the filter box. This design effectively isolates the leakage path of unfiltered air, avoids impurities from bypassing and contaminating the pneumatic motor, and ensures that there is no pressure loss during the transportation of high-pressure gas, maintaining the efficient operation of the pneumatic system.

[0022] 3. This air pump-driven mechanical transfer device uses a monitoring system that integrates pressure sensors and controllers to capture real-time changes in air pressure inside the filter box. When the filter element becomes clogged, causing abnormal pressure differences, the buzzer immediately triggers an audible and visual alarm to indicate the need for maintenance. This function not only avoids the lag of manual inspections but also prevents equipment damage caused by filter element failure, significantly improving system reliability.

[0037] Specifically, a buzzer 68 is installed on the left side of the filter housing 60. It is powered by an external power source. The buzzer 68 will sound an alarm when the air pressure is abnormal, prompting the staff to clean the coarse filter plate 61, the medium-efficiency filter plate 62, and the fine filter plate 63 in time.

[0043] In this embodiment, the air pump driven mechanical transfer equipment is started after the power of the air compressor pump 5 is turned on. The air compressor pump 5 generates a high-pressure airflow by compressing ambient air, which is transmitted to the air inlet port 600 of the filter 6 through the second air guide pipe 8. After the compressed air enters the filter box 60, it passes through three stages of filtration: a coarse filter plate 61, a medium-efficiency filter plate 62, and a fine filter plate 63. The coarse filter plate 61 intercepts large particulate pollutants, the medium-efficiency filter plate 62 adsorbs medium-sized particles and moisture, and the fine filter plate 63 removes oil mist and small impurities. The purified clean air is delivered to the reversing valve 7 through the first air guide pipe 70 via the air outlet port 601. By adjusting the reversing valve 7, the airflow direction is controlled, so that the compressed air drives the pneumatic motor 3 to rotate forward and backward through the first connecting pipe 71 or the second connecting pipe 72, thereby driving the transfer conveyor belt 2 to complete the automated transfer of materials.

[0044] When maintenance or filter replacement is required, rotating wheel 652 loosens threaded rod 65 and removes cover plate 64. At this time, coarse filter plate 61, medium-efficiency filter plate 62 and fine filter plate 63 can be quickly pulled out for replacement. The cooperation between positioning rod 644 and positioning tube 604 ensures that rectangular sealing plate 641 is accurately reset. After installation, tightening wheel 652 causes circular pressure plate 650 to press cover plate 64 through sealing rubber 651. First frame rubber pad 642 and second frame rubber pad 643 seal the gap between cover plate 64 and filter box 60. During operation, pressure sensor 67 monitors the air pressure change in the air collection hood 603 in real time. When the pressure is lower than the threshold, controller 69 triggers buzzer 68 to alarm, prompting cleaning or replacement of filter screen, ensuring continuous and efficient operation of equipment.
