Description

Technical Field

[0001] This utility model relates to the technical field of aluminum tube processing equipment, specifically to an aluminum tube inner wall spraying equipment. Background Technology

[0002] During the production and processing of aluminum tubes, due to the relatively reactive chemical properties of aluminum, it is usually necessary to use a spraying machine to spray the inner wall of the aluminum tube, making it difficult for the aluminum tube to react with other substances inside.

[0003] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.

[0004] The patented technology, disclosed in patent number "CN219400738U", discloses an aluminum tube inner wall spraying machine capable of uniform spraying. It includes an inner wall spraying machine body, on which an aluminum tube body is detachably mounted. A fixing device is fixedly installed in the middle of the inner wall spraying machine body, and an adjusting device is fixedly installed on the outer surface of the fixing device. This technology allows the double-threaded screw to rotate within a fixed frame by rotating a first knob. This causes the transmission rod, clamping plate, and soft pad to slide towards each other along the inner wall of the fixed frame, clamping and fixing the aluminum tube body. The inner wall spraying machine body then rotates the aluminum tube body while its spraying device vertically descends to uniformly spray the inner surface of the aluminum tube body. Conversely, rotating the first knob in the opposite direction releases the fixing of the aluminum tube body, allowing it to be removed. This structure ensures that the aluminum tube body is stably fixed to the base of the inner wall spraying machine body while rotating, preventing it from shaking and thus resulting in more uniform spraying.

[0005] However, the above-mentioned device still has the following problems during implementation:

[0006] Dust and other impurities may remain during the processing and storage of aluminum tubes. This spraying machine does not have the function of cleaning aluminum tubes. If these impurities are not thoroughly removed, they may cause the coating to have poor adhesion to the inner wall of the aluminum tube, making the coating easy to peel off, fall off or blister, thus affecting the quality and service life of the aluminum tube. Utility Model Content

[0007] The purpose of this invention is to provide an aluminum tube inner wall spraying device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A spraying device for the inner wall of an aluminum tube includes a connecting block and a machine body. Two connecting seats are fixedly connected to the outer wall of the connecting block. A first motor is fixedly installed at the end of one of the connecting seats away from the connecting block. A rotating rod is fixedly connected to the output shaft of the first motor, and a cleaning mechanism is provided at the end of the rotating rod away from the connecting seat.

[0010] The cleaning mechanism includes a fixed block, an outer shell fixedly connected to the outer wall of the fixed block, and a sliding plate slidably connected to the inner wall of the outer shell. A first groove is formed at one end of the sliding plate, and a sliding rod is slidably connected to the inner wall of the first groove. A second groove is formed through the inner wall of the first groove. A protrusion is fixedly connected to the outer wall of the sliding rod, and the outer wall of the protrusion is slidably connected to the inner wall of the second groove. A spring is fixedly connected to one end of the sliding rod, and the end of the spring away from the sliding rod is fixedly connected to the inner wall of the first groove. A cleaning head is fixedly connected to the end of the sliding rod away from the spring. The side wall of the sliding plate has toothed grooves.

[0011] Preferably, a connecting rod is rotatably and fixedly connected to the inner wall of the outer casing, a first gear is rotatably connected to the outer wall of the connecting rod, and the teeth of the first gear mesh with the inner wall of the tooth groove; a toothed ring is rotatably connected to the inner wall of the outer casing; a second gear is rotatably connected to the outer wall of the connecting rod, and the teeth of the second gear mesh with the teeth of the toothed ring; a second motor is fixedly installed on the inner wall of the outer casing, and a third gear is fixedly connected to the output shaft of the second motor, the teeth of the third gear mesh with the teeth of the toothed ring; and multiple connecting plates are fixedly connected between the outer wall of the fixing block and the inner wall of the outer casing.

[0012] Preferably, a mounting block is fixedly connected to the top of the machine body, and a hydraulic cylinder is fixedly mounted on the top of the mounting block.

[0013] Preferably, the sidewall of the connecting block is fixedly connected to the output shaft of the hydraulic cylinder.

[0014] Preferably, a spraying assembly is fixedly installed at the end of another connecting seat away from the connecting block.

[0015] Preferably, a processing disc is rotatably connected to the side wall of the machine body.

[0016] Preferably, the sidewall of the processing disk is provided with a plurality of processing positions.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. During the spraying process, the end of the aluminum tube presses against the outer surface of the cleaning head, which then enters the aluminum tube. A spring applies pressure to the cleaning head, keeping its outer surface in constant contact with the inner wall of the aluminum tube. The cleaning head then slides and rotates against the inner wall of the aluminum tube, efficiently cleaning dust and other impurities. The high-speed rotation of the fixed block blows out any loose impurities, ensuring the cleanliness of the inner wall of the aluminum tube meets the spraying requirements. This guarantees uniform spraying inside the aluminum tube, prevents corrosion of the inner wall, and extends the service life of the aluminum tube.

[0019] 2. Before the spraying operation, the gear ring drives multiple second gears to rotate, causing the first gear to drive the corresponding sliding plate to spread outward, thereby changing the diameter of the aluminum tube being cleaned. Through the adjustability and adaptability of the cleaning head height, the same equipment can handle aluminum tubes of various sizes without replacing or adjusting the entire device. This greatly improves the flexibility and practicality of the equipment, reduces equipment costs, and increases production efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A spraying device for the inner wall of an aluminum tube includes a connecting block 1 and a machine body 6. Two connecting seats 2 are fixedly connected to the outer wall of the connecting block 1. A first motor 3 is fixedly installed at the end of one connecting seat 2 away from the connecting block 1. A rotating rod 4 is fixedly connected to the output shaft of the first motor 3, and a cleaning mechanism 5 is provided at the end of the rotating rod 4 away from the connecting seat 2.

[0028] Furthermore, the cleaning mechanism 5 includes a fixing block 501, with a housing 502 fixedly connected to the outer wall of the fixing block 501, and a sliding plate 503 slidably connected to the inner wall of the housing 502. A first groove 504 is formed at one end of the sliding plate 503, and a sliding rod 505 is slidably connected to the inner wall of the first groove 504. A second groove 506 is formed through the inner wall of the first groove 504. A protrusion 507 is fixedly connected to the outer wall of the sliding rod 505, and the outer wall of the protrusion 507 is slidably connected to the inner wall of the second groove 506. A spring 508 is fixedly connected to one end of the sliding rod 505. One end of 508 away from the slide bar 505 is fixedly connected to the inner wall of the first slide groove 504. The end of the slide bar 505 away from the spring 508 is fixedly connected to the cleaning head 509. The side wall of the sliding plate 503 is provided with a toothed groove 510. The top of the machine body 6 is fixedly connected to the mounting block 7, and the top of the mounting block 7 is fixedly installed with a hydraulic cylinder 9. The side wall of the connecting block 1 is fixedly connected to the output shaft of the hydraulic cylinder 9. The other connecting seat 2 is fixedly installed with a spraying assembly 8 at one end away from the connecting block 1. The side wall of the machine body 6 is rotatably connected to the processing plate 10, and the side wall of the processing plate 10 is provided with several processing positions 11.

[0029] More specifically, in this embodiment, during the processing and storage of aluminum tubes, dust and other impurities may remain on the inner wall of the aluminum tubes. The presence of these impurities has an adverse effect on the coating effect and quality of the aluminum tubes. Therefore, cleaning the aluminum tubes before coating helps to improve the effect of subsequent coating.

[0030] First, power is supplied to the equipment, causing the processing disc 10 to rotate intermittently on the inner wall of the processing position 11. Then, the aluminum tube to be coated is placed in the processing position 11. The rotation of the processing disc 10 then transports the aluminum tube to the position corresponding to the cleaning mechanism 5. Next, the hydraulic cylinder 9 drives the connecting block 1 to move, which in turn moves the connecting seat 2 synchronously. Then, the first motor 3 drives the rotating rod 4 to move the cleaning mechanism 5 into the aluminum tube, causing the cleaning head 509 to slide against the inner wall of the aluminum tube. During this process, the end of the aluminum tube presses against the surface of the cleaning head 509, causing the cleaning head 509 to drive the sliding rod 505 to slide along the inner wall of the first sliding groove 504. Simultaneously, the protrusion 507 slides along the inner wall of the second sliding groove 506, making the sliding process of the sliding rod 505 more stable. Then, the spring 508 is compressed, and the force generated by the compression always applies pressure to the cleaning head 509 through the sliding rod 505, causing the cleaning head 509 to... 9 remains attached to the inner wall of the aluminum tube. When the hydraulic cylinder 9 retracts after outputting, the first motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 drives the outer shell 502 to rotate through the fixed block 501. Then, the outer shell 502 drives the cleaning head 509 to rotate through the sliding rod 505. During the rotation of the cleaning head 509, its outer surface polishes and cleans the inner wall of the aluminum tube, causing dust and other impurities to fall off the inner wall of the aluminum tube. Multiple connecting plates are fixedly connected between the outer wall of the fixed block (501) and the inner wall of the outer shell (502). When the cleaning mechanism 5 rotates at high speed, the multiple connecting plates connected to the fixed block 501 and the outer shell 502 are tilted to achieve the effect of a fan, which blows the fallen impurities outward, thereby achieving the function of cleaning the aluminum tube. After the hydraulic cylinder 9 retracts, the processing plate 10 rotates to transport the cleaned aluminum tube to the spraying station corresponding to the spraying component 8. Example 2:

[0031] Based on the above embodiments, a connecting rod 511 is rotatably and fixedly connected to the inner wall of the outer shell 502, and a first gear 512 is rotatably connected to the outer wall of the connecting rod 511, and the teeth of the first gear 512 mesh with the inner wall of the tooth groove 510.

[0032] Furthermore, a gear ring 514 is rotatably connected to the inner wall of the housing 502, and a second gear 513 is rotatably connected to the outer wall of the connecting rod 511. The teeth of the second gear 513 mesh with the teeth of the gear ring 514. A second motor 515 is fixedly installed on the inner wall of the housing 502, and a third gear 516 is fixedly connected to the output shaft of the second motor 515. The teeth of the third gear 516 mesh with the teeth of the gear ring 514.

[0033] More specifically, in this embodiment, before spraying the aluminum tube, the cleaning mechanism 5 can be adjusted according to the size of the aluminum tube. The second motor 515 drives the third gear 516 to rotate, and then the third gear 516 drives the gear ring 514 to rotate inside the housing 502, causing the gear ring 514 to drive multiple second gears 513 to rotate. Then, the second gears 513 drive the first gear 512 to rotate through the connecting rod 511. The rotation of the first gear 512 can drive the sliding plate 503 to slide on the inner wall of the housing 502. At the same time, the sliding plate 503 drives the cleaning head 509 to slide outward through the sliding rod 505. By sliding multiple cleaning heads 509 outward, the diameter that can be cleaned on the aluminum tube is expanded, so that the cleaning mechanism 5 can handle the spraying of aluminum tubes of various sizes. This structure allows for precise adjustment according to the size of the aluminum tube, so that the same equipment can handle aluminum tubes of various sizes without replacing or adjusting the entire device, which greatly improves the flexibility and practicality of the equipment.

[0034] Working principle: First, power is supplied to the equipment, causing the processing disc 10 to rotate intermittently on the inner wall of the processing position 11. Then, the aluminum tube to be sprayed is placed in the processing position 11. The rotation of the processing disc 10 then transports the aluminum tube to the position corresponding to the cleaning mechanism 5. Next, the hydraulic cylinder 9 drives the connecting block 1 to move, which in turn moves the connecting seat 2 synchronously. Then, the first motor 3 drives the rotating rod 4 to move the cleaning mechanism 5 into the aluminum tube, causing the cleaning head 509 to slide against the inner wall of the aluminum tube. During this process, the end of the aluminum tube presses against the surface of the cleaning head 509, causing the cleaning head 509 to drive the sliding rod 505 to slide along the inner wall of the first sliding groove 504. Simultaneously, the protrusion 507 slides along the inner wall of the second sliding groove 506, making the sliding process of the sliding rod 505 more stable. Then, the spring 508 is compressed, generating… The force will always apply pressure to the cleaning head 509 through the slide rod 505, keeping the cleaning head 509 in contact with the inner wall of the aluminum tube. When the hydraulic cylinder 9 retracts after outputting, the first motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 will drive the outer shell 502 to rotate through the fixed block 501. Then, the outer shell 502 will drive the cleaning head 509 to rotate through the slide rod 505. During the rotation of the cleaning head 509, its outer surface will polish and clean the inner wall of the aluminum tube, causing dust and other impurities to fall off the inner wall of the aluminum tube. Multiple connecting plates are fixedly connected between the outer wall of the fixed block 501 and the inner wall of the outer shell 502. When the cleaning mechanism 5 rotates at high speed, the multiple connecting plates connected to the fixed block 501 and the outer shell 502 will be tilted to achieve the effect of a fan, blowing the fallen impurities outward, thereby achieving the function of cleaning the aluminum tube.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
