Description

Technical Field

[0001] The utility model relates to the technical field of air filter processing equipment, in particular to an air filter adsorption and transfer device. Background Art

[0002] After air filters are boxed and packaged, they need to be stacked from bottom to top onto pallets for transport. Conventional manual handling is time-consuming, labor-intensive, and inefficient. Alternatively, some methods utilize vacuum suction to lift the air filters and their packaging boxes together for transport and stacking. This method works by first placing a vacuum suction cup in contact with the air filter packaging box, activating the vacuum device to create negative pressure within the cup, thereby securing the packaging box. This allows the air filters to be lifted and transported. Once the air filters are transferred and stacked, air is steadily inflated into the cup until the negative pressure reaches zero or a slightly positive level. The cup then releases the air filter packaging box, completing the transfer. In this method, since the vacuum cup is attached to the air filter packaging box, the surface quality of the box and the quality of the tape used to wrap the box can lead to unstable suction. This poses a safety risk of the air filter falling during transport, making it difficult to meet the transport requirements of filters. Utility Model Content

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] like Figure 1-7 The air filter adsorption transfer device of this embodiment is shown, which can lift and transfer the air filter to a designated location. In this embodiment, the air filter is a packaged air filter, that is, an air filter including an outer packaging carton.

[0031] The suction transfer device comprises a main hanger 1 and several independent units spaced laterally on the main hanger 1. The main hanger 1 is equipped with a lifting ring 12, which allows a crane or other lifting equipment to lift and move the main hanger 1. The independent units comprise a vacuum suction assembly and a steering support assembly. The vacuum suction assembly is used to suction the air filter. Specifically, the vacuum suction assembly comprises a crossbeam 2, a vacuum suction cup 3, and a vacuum extraction device. The crossbeam 2 extends laterally and has a closed air cavity 21 formed therein. The vacuum suction cups 3 are spaced laterally below the crossbeam 2. The vacuum suction cups 3 are conventional components of the prior art, and their operating principles are described in the Background Technology section. Threaded holes 23 are machined on the bottom surface of the crossbeam 2, corresponding to the vacuum suction cups 3. These threaded holes 23 communicate with the air cavity 21. The suction end of the vacuum suction cup 3 is threadedly connected to the threaded hole 23, thereby securely connecting the vacuum suction cup 3 to the crossbeam 2 and communicating with the air cavity 21. The vacuum pump is connected to the air cavity 21 and is used to evacuate the air cavity 21, thereby creating a vacuum inside the vacuum cup 3 so that it can be attached to the target object. In this embodiment, the vacuum pump is a conventional device that is arranged on the ground or on a lifting device such as a crane. A connection port 24 that communicates with the air cavity 21 is machined on the top surface of the crossbeam 2. The air pipe of the vacuum pump is connected to the connection port 24, so that it communicates with the air cavity 21 through the connection port 24.

[0032] The steering support assembly includes a longitudinal beam 4, a sleeve 5, a drive assembly, a steering rod 6, and a support plate 61. The longitudinal beam 4 is arranged longitudinally and fixedly mounted on the crossbeam 2. The crossbeam 2 and longitudinal beam 4 intersect to form a cross-shaped structure. The sleeve 5 is a hollow structure, mounted at each end of the longitudinal beam 4, and has a vertically extending central axis. Mounting holes are machined at each end of the longitudinal beam 4, into which the sleeve 5 is installed with a clearance fit. The sleeve 5 is positioned vertically on the longitudinal beam 4, allowing it to rotate about its central axis within the mounting holes. The drive assembly is fixedly mounted on the longitudinal beam 4 and is used to drive the sleeves 5 on both sides to rotate about their central axes between a first position and a second position. Specifically, the drive assembly includes a driver 7 and an arm 71. The driver 7 has two ends that move synchronously. The driver 7 is preferably a conventional bidirectional telescopic cylinder. An air compressor is located on a lifting device such as a crane or on the ground to provide air to the bidirectional telescopic cylinder.

[0033] The aforementioned long arms 71 are arranged on either side of the actuator 7. The first end of the long arms 71 is rotatably connected to the sleeve 5, and the second end is rotatably connected to the corresponding end of the actuator 7. With this structural design, when the two ends of the actuator 7 move synchronously, the sleeves 5 on both sides rotate synchronously under the linkage of the long arms 71, allowing them to switch back and forth between the first and second positions.

[0034] The aforementioned steering rod 6 is inserted into the sleeve 5 for vertical movement. A limiting structure is arranged between the steering rod 6 and the sleeve 5 to restrict relative rotation between the two. This limiting structure allows the steering rod 6 to rotate synchronously with the sleeve 5 and to move up and down relative to the sleeve 5. Specifically, the limiting structure includes a cooperating positioning protrusion 51 and a positioning recess 64. The positioning protrusion 51 is machined on the inner wall of the sleeve 5, while the positioning recess 64 is machined on the outer wall of the steering rod 6. During assembly, when the steering rod 6 is inserted into the sleeve 5, the positioning protrusion 51 is simultaneously inserted into the positioning recess 64, thereby acting as a limiting mechanism.

[0035] A limit block 62 is installed at the top of the steering rod 6 to limit the downward movement of the steering rod 6 relative to the sleeve 5. A support plate 61 is installed at the bottom of the steering rod 6, and the support plate 61 extends in the horizontal direction. When the sleeve 5 rotates to the aforementioned first position, the steering rod 6 rotates accordingly and drives the support plate 61 to extend under the vacuum adsorption assembly, so that upper and lower limit spaces are formed between the support plate 61 and the vacuum adsorption assembly. When the sleeve 5 rotates to the second position, the steering rod 6 rotates accordingly and drives the support plate 61 away from the bottom of the vacuum adsorption assembly to stay away from the space below the vacuum adsorption assembly, thereby preventing the support plate 61 from interfering with the descent of the vacuum adsorption assembly, allowing the vacuum adsorption assembly to descend and contact and adsorb on the air filter.

[0036] A counterweight 63 is mounted on the limiting block 62. The counterweight 63 can increase the overall weight of the steering rod 6 and the supporting plate 61, thereby allowing the steering rod 6 and the supporting plate 61 to descend smoothly.

[0037] In this embodiment, the main hanger 1 is equipped with a laterally extending guide rod. The crossbeams 2 of each vacuum suction assembly are slidably mounted on the guide rods through guide holes, allowing for transverse movement on the main hanger 1. This allows for adjustment of the lateral position of each independent unit on the main hanger 1. A locking mechanism is installed between the crossbeam 2 and the main hanger 1. When locked, the locking mechanism restricts movement of the crossbeam 2 relative to the main hanger 1, thereby securing each independent unit in its current position. Specifically, the locking mechanism includes a positioning pin 13. A plurality of first positioning holes 11 are formed at intervals along the crossbeam 2. A plurality of second positioning holes are formed at intervals along the main hanger 1. The positioning pins 13 engage with the corresponding first and second positioning holes 11 and 22 to achieve the aforementioned locked position. This structural design allows for adjustment of the lateral position of each independent unit on the main hanger 1, thereby adjusting the suction range of the vacuum suction assembly to meet the suction and transfer requirements of air filters of varying lengths.

[0038] During operation, the actuator 7 rotates the sleeves 5 to their second position. The steering rods 6 rotate accordingly, driving the support plates 61 away from below the vacuum assembly. A crane or other lifting equipment then lowers the main hanger 1 and each of the individual units. As the vacuum assembly descends to contact the air filter, the steering rods 6 and support plates 61 contact the ground or other objects surrounding the air filter and move upward, allowing the vacuum assembly to descend smoothly without being blocked by the steering rods 6. The vacuum pump is activated, allowing the vacuum cups 3 to adhere to the top surface of the air filter. After the vacuum cups 3 have completed their attachment, the main hanger 1 is lifted. During this lifting process, the steering rods 6 and support plates 61 move downward under their own weight until they are restrained by the stop blocks 62. The actuator 7 rotates the sleeves 5 to their first position. The steering rods 6 rotate accordingly, driving the support plates 61 below the air filter to support the air filter in and out. After this operation is complete, the main hanger 1 is lifted again to transfer the air filter. Through this method, the air filter can be transferred by vacuum adsorption, and the air filter can be supported from below during the transfer process to prevent the air from falling during the transfer process, effectively meeting the transfer and transportation requirements of the air filter. During the adsorption and transfer process, the adsorption operations of the vacuum adsorption components of each independent unit do not interfere with each other. If one or more groups of vacuum adsorption components fail, the overall structure can still temporarily perform the adsorption and transfer operation, thus providing effective safety protection for the air filter transfer process and strong practicality.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
