Description

Technical Field

[0001] This invention relates to the field of material handling technology, and in particular to an automated conveying device for heat treatment of formed copper tubes. Background Technology

[0002] In the heat treatment of formed copper tubes, automated conveying systems are a crucial component. They not only transport the copper tubes from one process stage to another but may also be involved in heating and cooling functions. The design and operation of automated conveying systems directly affect the heat treatment effect of the copper tubes. With the increasing intelligence and automation of industrial production, intelligent heat treatment production lines are gradually becoming an indispensable part of the copper tube processing industry. Intelligent production lines integrate advanced information technology, sensing technology, automatic control systems, and big data analysis, enabling them to significantly improve production efficiency and achieve energy conservation and emission reduction while ensuring copper tube quality.

[0003] In automated conveying devices for heat treatment of formed copper tubes, conveying rollers are typically used to transport the copper tubes. Since the conveying rollers usually operate in a high-temperature environment, their surfaces are prone to accumulating contaminants such as metal shavings and oil stains. However, existing conveying devices are not convenient for automatic maintenance of the conveying rollers, which can lead to the accumulation of contaminants on the surface of the conveying rollers. This may increase the friction of the conveying rollers, thereby increasing the conveying resistance and slowing down the conveying speed of the copper tubes. Long-term uncleaned contaminants may cause wear on the surface of the conveying rollers. Especially under high-temperature conditions, oil stains and metal shavings may react chemically or physically with the conveying rollers, resulting in damage or corrosion to the surface of the conveying rollers and reducing their service life.

[0004] In summary, the existing technology lacks a technology for automatic maintenance of the conveyor roller surface. Summary of the Invention

[0013] Preferably, the transmission mechanism includes a transmission wheel A, which is meshed with a driving wheel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a conveyor roller maintenance seat, when the conveyor roller maintenance seat moves upward, the rubber wheel on its internal brush rod will contact the conveyor roller. At this time, when the conveyor roller rotates, it can drive the brush rod to rotate and drive the scraper to move back and forth. This allows the scraper to automatically maintain the surface of the conveyor roller, timely removing contaminants such as metal shavings and oil stains, avoiding the trouble of manual cleaning, improving cleaning efficiency, and keeping the surface of the conveyor roller clean helps to maintain high-efficiency conveying performance. By reducing manual intervention, improving cleaning efficiency, extending equipment life, and ensuring product quality, it improves the stability and efficiency of the overall production process, which has great advantages.

[0017] 2. By installing a rotatable protective cover on the outside of the conveyor roller, it can cover the conveyor roller when it is not in use, which can effectively prevent external contaminants from directly contacting the surface of the conveyor roller, keep the conveyor roller clean, avoid the accumulation of contaminants, thereby extending the service life of the equipment and reducing the frequency of cleaning and maintenance. When the conveyor roller is not in use, the protective cover can effectively shield the surface of the roller track, prevent the roller track from being subjected to external physical impact or corrosion, reduce the wear of the roller track surface, and protect its long-term stable operation.

[0018] 3. By setting up a transmission mechanism and an air compressor seat, while the conveying roller rotates to transport the copper tube, it can drive the transmission mechanism, which in turn drives the piston plate inside the air compressor seat to move quickly. This allows the exhaust pipe on the air compressor seat to spray air onto the copper tube, effectively removing metal shavings, dust, oil, and other contaminants from the surface of the copper tube. Keeping the surface of the copper tube clean helps improve product quality and prevents contaminants from affecting the subsequent heat treatment process of the copper tube.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-9An automated conveying device for heat treatment of formed copper tubes is shown, comprising a conveying frame 1, a plurality of conveying rollers 2 rotatably connected to the conveying frame 1, a conveying roller protection mechanism 3 rotatably connected to the conveying frame 1, a fixed frame 4 fixedly connected to the conveying frame 1, a movable seat 5 slidably fitted on the fixed frame 4, a mounting seat 6 slidably fitted on the movable seat 5, a conveying roller maintenance seat 7 movably inserted into the mounting seat 6, a plurality of transmission mechanisms 8 rotatably connected to one side of the conveying frame 1, and a plurality of compressed air seats 9 fixedly connected to one side of the conveying frame 1.

[0031] like Figure 2 As shown, a drive wheel 201 is fixedly connected to one end of the conveyor roller 2.

[0032] like Figure 3 As shown, the conveyor roller protection mechanism 3 includes a motor A301, which is fixedly connected to the conveyor frame 1. A transmission shaft 302 is fixedly connected to the output end of the motor A301. Multiple worm sleeves 303 are fixedly connected to the outer wall of the transmission shaft 302. A worm wheel sleeve 304 is meshed and driven on one side of the worm sleeve 303. The worm wheel sleeve 304 is rotatably connected to one end of the conveyor roller 2. A protective cover 305 is fixedly connected to the worm wheel sleeve 304.

[0033] like Figure 4 As shown, a threaded rod 401 is rotatably connected to the fixed frame 4. One end of the threaded rod 401 passes through the fixed frame 4 and is fixedly connected to a motor B402. The motor B402 is fixedly connected to the fixed frame 4, and the threaded rod 401 is threadedly connected to the movable seat 5.

[0034] like Figure 5 As shown, an electric actuator 601 is fixedly connected to the bottom of the mounting base 6. The electric actuator 601 is fixedly connected to the movable base 5. Mounting holes 602 are provided on both sides of the mounting base 6.

[0035] like Figure 6 , Figure 7 As shown, mounting rods 701 are fixedly connected to the bottom of both sides of the conveyor roller maintenance seat 7. The mounting rods 701 are movably inserted into the mounting holes 602. A brush rod 702 is provided on the inner wall of the conveyor roller maintenance seat 7. Rubber wheels 703 are fixedly connected to both ends of the brush rod 702. The rubber wheels 703 are in frictional contact with the outer wall of the conveyor roller 2. Bending rods 704 are fixedly connected to both ends of the brush rod 702. The other end of the bending rod 704 is rotatably connected to the inner wall of the conveyor roller maintenance seat 7.

[0036] A guide rod 705 is fixedly connected to the inner wall of the conveyor roller maintenance seat 7. A scraper 706 is slidably fitted on the guide rod 705. The scraper 706 is in frictional contact with the outer wall of the conveyor roller 2. Inclined trough plates 707 are fixedly connected to both ends of the scraper 706.

A connecting rod 709 is rotatably connected to the top end of the push rod 708. The other end of the connecting rod 709 is rotatably connected to the outer wall of the bent rod 704. The rotating conveyor roller 2 can drive the brush rod 702 connected to the rubber wheel 703 to rotate. At the same time, under the action of the scraper 706, the oil stains on the outer wall of the conveyor roller 2 can be scraped off. Meanwhile, the bent rods 704 at both ends of the brush rod 702 can drive the push rod 708 connected to the connecting rod 709 to move back and forth. At this time, the push rod 708 will drive the scraper 706 connected to the inclined trough plate 707 to move back and forth.

[0037] By setting up a conveyor roller maintenance seat 7, when the conveyor roller maintenance seat 7 moves upward, the rubber wheel 703 on its internal brush rod 702 will contact the conveyor roller 2. At this time, when the conveyor roller 2 rotates, it can drive the brush rod 702 to rotate, and drive the scraper 706 to move back and forth. This allows the scraper 706 to automatically maintain the surface of the conveyor roller 2, and remove contaminants such as metal shavings and oil stains in a timely manner, avoiding the trouble of manual cleaning and improving cleaning efficiency. Keeping the surface of the conveyor roller 2 clean helps to maintain efficient conveying performance. By reducing manual intervention, improving cleaning efficiency, extending equipment life and ensuring product quality, it improves the stability and efficiency of the overall production process, which has great advantages.

[0038] like Figure 8 As shown, the transmission mechanism 8 includes a transmission wheel A801, which meshes with the drive wheel 201. A transmission wheel B802 is fixedly connected to one side of the transmission wheel A801, and the transmission wheel B802 is rotatably connected to the conveyor frame 1. A driven wheel 803 is meshed with the upper side of the transmission wheel B802, and the driven wheel 803 is rotatably connected to the conveyor frame 1. A rotating rod 804 is fixedly connected to the driven wheel 803, and a pressing wheel 805 is rotatably connected to the other end of the rotating rod 804. When the conveyor roller 2 rotates, it drives the connected drive wheel 201 to rotate. At this time, the drive wheel 201 drives the transmission wheel A801 ​​to rotate, which in turn drives the connected transmission wheel B802 to rotate. The transmission wheel B802 then drives the connected driven wheel 803 to rotate, which in turn drives the connected rotating rod 804 to rotate.

[0039] like Figure 9As shown, a piston plate 901 is slidably fitted onto the inner wall of the air compressor seat 9. Multiple springs 902 are fixedly connected to the bottom of the piston plate 901, and the other end of each spring 902 is fixedly connected to the inner wall of the bottom of the air compressor seat 9. An exhaust pipe 903 is slidably fitted through the piston plate 901 and fixedly connected to the air compressor seat 9. One end of the exhaust pipe 903 passes through the conveyor frame 1 and is fixedly connected to multiple sets of nozzles in an arc shape. An air inlet pipe is fixedly connected through the inner wall of the bottom of the air compressor seat 9. The top surface of the piston plate 901 is in slidable contact with the extrusion wheel 805. The extrusion wheel 805 on the rotating rod 804 contacts and extrudes the piston plate 901, causing the piston plate 901 to compress the air inside the air compressor seat 9 into the exhaust pipe 903, which then ejects the air through the nozzles on the exhaust pipe 903.

[0040] Working principle: When copper tubes need to be heat treated, the copper tubes are first transported to the heat treatment position using the conveyor roller 2. When the conveyor roller 2 is used, the motor A301 drives the connected drive shaft 302 to rotate. At this time, the drive shaft 302 drives the connected worm sleeve 303 to rotate. Then, the worm sleeve 303 drives the protective cover 305 connected to the worm gear sleeve 304 to rotate downward and retract.

[0041] The copper tube is then placed on the conveyor frame 1 and conveyed by the rotating conveyor roller 2. As the conveyor roller 2 rotates, it drives the connected drive wheel 201 to rotate. At this time, the drive wheel 201 drives the transmission wheel A801 ​​to rotate, which in turn drives the connected transmission wheel B802 to rotate. The transmission wheel B802 then drives the connected driven wheel 803 to rotate, which in turn drives the connected rotating rod 804 to rotate. Then, the extrusion wheel 805 on the rotating rod 804 contacts and extrudes the piston plate 901, causing the piston plate 901 to expel the air in the air pressure seat 9 into the exhaust pipe 903, and then spray it out through the nozzle on the exhaust pipe 903 to clean the surface of the copper tube.

[0042] Then, when the conveyor roller 2 is finished and needs maintenance, first rotate the protective cover 305 above the conveyor roller 2, then use the motor B402 to drive the threaded rod 401 to rotate, so that the threaded rod 401 can drive the moving seat 5 to move, so that the conveyor roller maintenance seat 7 is aligned with the conveyor roller 2, and then use the electric push rod 601 to drive the connected mounting seat 6 to move upward, so that the scraper 706 and the rubber wheel 703 contact the outer wall of the conveyor roller 2.

[0043] Then, the rotating conveyor roller 2 can drive the brush rod 702 connected to the rubber wheel 703 to rotate. At the same time, under the action of the scraper 706, the oil stains on the outer wall of the conveyor roller 2 can be scraped off. Meanwhile, the bent rods 704 at both ends of the brush rod 702 can drive the push rod 708 connected to the connecting rod 709 to move back and forth. At this time, the push rod 708 will drive the scraper 706 connected to the inclined chute plate 707 to move back and forth, improving its cleaning efficiency. At the same time, the rotating brush rod 702 can sweep the oil stains on the scraper 706 off and collect them in the conveyor roller maintenance seat 7.
