[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, the present invention provides an aluminum coil edge finishing mechanical device, comprising a base frame 1, on which an unwinding roller 2 is rotatably mounted, an aluminum strip 3 is wound on the unwinding roller 2, and the aluminum strip 3 is wound on the unwinding roller 2 to form an aluminum coil;

[0034] A guide roller 15 is rotatably mounted on the base frame 1 and adjacent to the unwinding roller 2;

[0035] The microcontroller 13 and the unwinding motor are mounted on the base frame 1, and the output shaft end of the unwinding motor is fixedly connected to the unwinding roller 2;

[0036] Two tensioning systems for elastically tensioning the aluminum strip 3 are provided on the base frame 1;

[0037] The tensioning system includes a tensioning frame 29, on which a group of T-shaped guide rods 30 are mounted. Each T-shaped guide rod 30 is slidably connected to the base frame 1. A tensioning spring 31 is sleeved on the T-shaped guide rod 30 and corresponds to the position between the base frame 1 and the tensioning frame 29. A tensioning roller 32 is rotatably mounted on the tensioning frame 29 to contact the aluminum strip 3.

[0038] During the aluminum coil edge finishing process, the unwinding roller 2 unwinds the aluminum strip 3, and the aluminum strip 3 passes through the guide roller 15 and comes into contact with the tensioning roller 32. The T-shaped guide rod 30 on the tensioning frame 29 can slide on the base frame 1. The tensioning spring 31 is sleeved on the T-shaped guide rod 30. Its elastic force causes the tensioning roller 32 to exert elastic tension on the aluminum strip 3. This elastic tension can effectively prevent the aluminum strip 3 from becoming loose or wrinkled during transportation, ensuring that the aluminum strip 3 is in a stable tension state during the subsequent finishing process, providing a good foundation for subsequent shaping, turning and grinding operations, and improving the finishing quality.

[0039] A power system is provided on the base frame 1 and at a position corresponding to the two tensioning systems. A vertical oscillating frame 4 that can be moved back and forth in the vertical direction is installed on the power system. A trimming frame 5 that can be moved back and forth along the axis of the unwinding roller 2 is installed on the vertical oscillating frame 4. The displacement stroke and displacement frequency of the vertical oscillating frame 4 and the trimming frame 5 change cyclically.

[0040] The power system includes a servo motor 17 mounted on the base frame 1, a first key shaft 18 is mounted on the output shaft end of the servo motor 17, a second key shaft 19 and a vertical screw 20 are rotatably mounted on the base frame 1, and a second synchronous toothed belt is connected between the second key shaft 19 and the vertical screw 20;

[0041] The vertical screw 20 is in transmission connection with the vertical vibration frame 4, on which the first hollow shaft 21 driven by the first key shaft 18, the second hollow shaft 22 linked to the second key shaft 19, and the longitudinal screw 23 are rotatably mounted;

[0042] The first hollow shaft 21 is provided with a first hollow groove with openings at both ends and slidingly connected to the first key shaft 18. The second hollow shaft 22 is fixedly provided with a second hollow groove with openings at both ends and slidingly connected to the second key shaft 19. The cross sections of the first hollow groove, the second hollow groove, the first key shaft 18 and the second key shaft 19 are all regular hexagons. A straight shaft 28 is rotatably mounted on the vertical vibration frame 4. A third synchronous toothed belt is connected between the straight shaft 28 and the second hollow shaft 22. A first bevel gear is mounted on the straight shaft 28 and the longitudinal screw 23, and the two first bevel gears are orthogonally meshed.

[0043] The first hollow shaft 21 is respectively mounted with a large-angle sector gear 24 and a small-angle sector gear 25. The first hollow shaft 21 is provided with two symmetrically arranged non-transmission sections at positions corresponding to the large-angle sector gear 24 and the small-angle sector gear 25.

[0044] The longitudinal screw 23 is in transmission connection with the trimming frame 5. The rotation connection between the vertical screw 20 and the base frame 1 and the rotation connection between the longitudinal screw 23 and the vertical vibration frame 4 are both provided with a steering torsion spring 26. Two differential gears 27 are mounted on the second hollow shaft 22. The two differential gears 27 are in transmission connection with the large-angle sector gear 24 and the small-angle sector gear 25 respectively.

[0045] The center angle corresponding to the large-angle sector gear 24 is 180°, the center angle corresponding to the small-angle sector gear 25 is 110°, and the center angles corresponding to the two non-transmission sections are both 35°. The radius of the large-angle sector gear 24 is 1.7 times the radius of the small-angle sector gear 25. The radius of the large-angle sector gear 24 is 13 times the radius of one corresponding differential gear 27, and the radius of the small-angle sector gear 25 is 10 times the radius of the other corresponding differential gear 27.

[0046] After the servo motor 17 is started, the first key shaft 18 installed on its output shaft end begins to rotate. At the same time, the second key shaft 19 and the vertical screw 20 are respectively rotatably installed on the base frame 1. The second key shaft 19 and the vertical screw 20 are connected by a second synchronous toothed belt. When the servo motor 17 drives the first key shaft 18 to rotate, it will indirectly drive the second key shaft 19 to rotate, and then rotate the vertical screw 20 through the second synchronous toothed belt. The vertical screw 20 is connected to the vertical vibration frame 4. The rotation of the vertical screw 20 will drive the vertical vibration frame 4 to move back and forth in the vertical direction.

[0047] During this process, a steering torsion spring 26 is provided at the rotational connection between the vertical screw 20 and the base frame 1. The function of the steering torsion spring 26 is to provide a certain elastic resistance and restoring force during the rotation of the vertical screw 20. When the vertical screw 20 rotates forward to cause the vertical vibration frame 4 to move upward, the steering torsion spring 26 will store elastic potential energy.

[0048] When the vertical screw 20 rotates in the opposite direction, the steering torsion spring 26 releases elastic potential energy to assist the vertical vibration frame 4 in moving downward, and affects the displacement stroke and frequency of the vertical vibration frame 4 through its elastic characteristics, causing it to form a cyclic change;

[0049] The first key shaft 18 drives the first hollow shaft 21 to rotate. When the first hollow shaft 21 rotates, the large-angle fan gear 24 and the small-angle fan gear 25 will rotate accordingly. Due to the existence of the non-transmission section, the large-angle fan gear 24 and the small-angle fan gear 25 will periodically engage and disengage with the differential gear 27 on the second hollow shaft 22. When the large-angle fan gear 24 or the small-angle fan gear 25 engages with the differential gear 27, it will drive the second hollow shaft 22 to rotate. The second hollow shaft 22 drives the longitudinal screw 23 to rotate through a series of transmission components. The longitudinal screw 23 is connected to the trimming frame 5. The rotation of the longitudinal screw 23 will drive the trimming frame 5 to move back and forth along the axis of the unwinding roller 2.

[0050] At the same time, a steering torsion spring 26 is also provided at the rotation connection between the longitudinal screw 23 and the vertical vibration frame 4. The steering torsion spring 26 also provides elastic resistance and restoring force during the rotation of the longitudinal screw 23, affecting the displacement stroke and frequency of the trimming frame 5, so that it forms a cyclic change like the vertical vibration frame 4;

[0051] The displacement stroke and displacement frequency of the vertical oscillating frame 4 and the trimming frame 5 are cyclically changed, so that the shaping roller 6 installed on the trimming frame 5 and the finishing assembly installed in the turning frame 7 on the vertical oscillating frame 4 can process the edge of the aluminum strip 3 at different positions and frequencies;

[0052] At different parts of the edge of the aluminum strip 3, according to the degree of defects and material properties, the shaping roller 6 can shape the aluminum strip 3 at different pressures and positions, and the finishing component can perform turning and grinding operations at different angles and forces. This can more effectively remove burrs and uneven defects on the edge of the aluminum strip 3, making the edge surface of the aluminum strip 3 smoother and flatter, thereby improving the finishing quality of the edge of the aluminum strip 3;

[0053] Through the cyclically changing displacement stroke and frequency, the shaping roller 6, the turning tool 10, the turning roller 11 and the grinding roller 12 can complete multiple processing operations in one processing process, reducing the processing steps and time. In one reciprocating displacement process, the shaping roller 6 can shape the edge of the aluminum strip 3 multiple times, and the finishing assembly can turn and grind the edge of the aluminum strip 3 multiple times, thereby improving the processing efficiency of the edge finishing of the aluminum strip 3;

[0054] During production, transportation, or storage, the edges of the aluminum strip 3 may be slightly deformed, uneven, or bent. If not shaped, subsequent turning may result in uneven thickness, over- or under-cutting of parts, affecting the finishing quality and accuracy. Furthermore, the uneven edges of the aluminum strip 3 may cause unstable contact between the turning tool 10 and the aluminum strip 3, resulting in vibration and jitter, which not only affects the surface finish of the turning, but also aggravates wear of the turning tool 10 and may even damage the turning tool 10, increasing production costs.

[0055] At the same time, the turning process requires that the material has a certain degree of flatness and regularity. Shaping can make the aluminum strip 3 better adapt to the turning requirements. Shaping improves the turning accuracy, allowing the turning tool 10 to cut more accurately along the predetermined trajectory, reducing errors, and making the edge size and shape of the aluminum strip 3 more in line with the design requirements.

[0056] Through pre-shaping, the turning surface quality is improved, the stable contact reduces vibration and runout, making the surface smoother and the roughness reduced;

[0057] At the same time, the shaping method prolongs the service life of the turning tool 10, stabilizes turning, reduces wear and damage, reduces the frequency and cost of tool replacement, and reduces production downtime;

[0058] The realization of pre-shaping effect enhances the consistency of finishing effect, makes the processing effect of each part more uniform, and improves the stability and reliability of finishing quality;

[0059] Two shaping rollers 6 are rotatably mounted on the trimming frame 5. Both shaping rollers 6 are made of stainless steel. The length of the shaping rollers 6 is 1.4 times the width of the aluminum strip 3.

[0060] The shaping roller 6 is equipped with a built-in electric heating rod;

[0061] An electric heating block 16 is installed in the trimming frame 5, and the heating temperature of the electric heating rod and the electric heating block 16 is 450°C;

[0062] The electric heating block 16 and the electric heating rod are both equipped with built-in temperature sensors, which are linked to the microcontroller 13 for precise temperature control of the electric heating block 16 and the electric heating rod;

[0063] When the aluminum strip 3 passes through the shaping roller 6, the electric heating rod built into the shaping roller 6 and the electric heating block 16 in the trimming frame 5 start to heat up to 450°C. At this temperature, the material properties of the aluminum strip 3 will change, and its hardness and toughness will be adjusted, making the aluminum strip 3 easier to shape. The shaping roller 6 is made of stainless steel and its length is 1.4 times the width of the aluminum strip 3. It can effectively shape the entire width direction of the aluminum strip 3. By heating and shaping the aluminum strip 3, some minor deformations and unevenness at the edge of the aluminum strip 3 can be eliminated, making the edge of the aluminum strip 3 more regular, providing a better foundation for subsequent turning and grinding processes;

[0064] A turning frame 7 is fixedly mounted on the vertical vibration frame 4, and a pitch adjustment component and a reversing shaft 8 are mounted on the turning frame 7. The reversing shaft 8 is driven by a power system and periodically changes the direction and speed of rotation. Two symmetrically arranged turning tables 9 with adjustable spacing are installed on the pitch adjustment component, and finishing components are mounted on the two turning tables 9.

[0065] The finishing assembly includes a turning tool 10 mounted on a turning table 9 and a turning roller 11 and a grinding roller 12 rotatably connected to the turning table 9. A first synchronous toothed belt is connected between the turning roller 11 and the grinding roller 12, and the grinding roller 12 is driven by a reversing shaft 8.

[0066] A waste storage drawer 14 with an open top is clamped on the inner wall of the base frame 1 and corresponding to the position below the turning roller 11;

[0067] The grinding roller 12 is evenly covered with steel wire bristles, the thickness of the steel wire bristles is 2.5 cm, the height of the grinding roller 12 and the turning roller 11 are both 7 times the thickness of the aluminum strip 3, and the axes of the grinding roller 12 and the turning roller 11 are perpendicular to the horizontal plane;

[0068] A third hollow shaft 34 is rotatably mounted on the turning table 9. A third hollow groove is fixedly formed inside the third hollow shaft 34, with both ends open and slidably connected to the reversing shaft 8. The cross-sections of the third hollow groove and the reversing shaft 8 are both regular hexagonal. Second bevel gears are mounted on the grinding roller 12 and the third hollow shaft 34, and the two second bevel gears are orthogonally meshed. A belt connecting section 35 is provided on the reversing shaft 8, and an elastic tensioning transmission belt 36 is connected to the longitudinal screw 23 through a transmission connection.

[0069] The elastic tensioning transmission belt 36 is made of rubber. The elastic tensioning transmission belt 36 can elastically compensate for the displacement of the trimming frame 5. The length of the belt connecting section 35 is 8 times the width of the elastic tensioning transmission belt 36.

[0070] The surface of the elastic tensioning transmission belt 36 is provided with anti-slip textures;

[0071] When the aluminum strip 3 passes through the turning frame 7, the distance adjustment component can adjust the distance between the two turning tables 9 according to the actual width of the aluminum strip 3 to meet the finishing requirements of aluminum strips 3 of different specifications. The power system drives the reversing shaft 8 to rotate, and the reversing shaft 8 periodically changes the rotation direction and rotation speed, and drives the longitudinal screw 23 to rotate through the belt connecting section 35 and the elastic tensioning transmission belt 36. The longitudinal screw 23 drives the grinding roller 12 to rotate through the third hollow shaft 34 and the second bevel gear. The grinding roller 12 drives the turning roller 11 to rotate through the first synchronous toothed belt. The turning tool 10 on the turning table 9 performs a turning operation on the edge of the aluminum strip 3 to remove excess parts and burr defects on the edge of the aluminum strip 3;

[0072] The turning roller 11 further performs fine processing on the surface after turning, and the wire brush bristles evenly distributed on the grinding roller 12 grind the surface after turning and turning roller 11 processing, so that the edge surface of the aluminum strip 3 is smoother. At the same time, the waste storage drawer 14 connected to the inner wall of the base frame 1 corresponding to the position below the turning roller 11 can collect waste generated during the turning and grinding process, and keep the working environment clean. The elastic tensioning transmission belt 36 is made of rubber material, which can elastically compensate for the displacement of the trimming frame 5 to ensure the stability of the transmission. Compared with the existing technology, the turning and grinding assembly can perform comprehensive and fine processing on the edge of the aluminum strip 3 through the coordinated action of the turning tool 10, the turning roller 11 and the grinding roller 12, thereby improving the finishing quality of the edge of the aluminum strip 3, and the waste collection design is more environmentally friendly and humane.

[0073] After the servo motor 17 is started, the first key shaft 18 at its output shaft end rotates, driving the first hollow shaft 21 to rotate. The large-angle sector gear 24 and the small-angle sector gear 25 on the first hollow shaft 21 periodically engage with the differential gear 27 on the second hollow shaft 22. Due to the different radii of the large-angle sector gear 24 and the small-angle sector gear 25 and the existence of the non-transmission section, the speed and direction of the second hollow shaft 22 change periodically, and are transmitted to the reversing shaft 8 through the power system to achieve its reciprocating speed change;

[0074] The reciprocating change of the rotation direction of the grinding roller 12 and the turning roller 11 is related to the movement of the reversing shaft 8. The rotation direction and speed change of the reversing shaft 8 are transmitted to the grinding roller 12 through the power system. The turning roller 11 and the grinding roller 12 are connected by the first synchronous toothed belt drive, and the rotation direction changes accordingly.

[0075] The grinding roller 12 and the turning roller 11 reciprocate and vibrate in a direction perpendicular to the aluminum strip 3 because the vertical screw 20 in the power system rotates under the drive of the second key shaft 19 and the second synchronous toothed belt, causing the vertical vibration frame 4 to move back and forth in the vertical direction. The turning frame 7 is fixed on the vertical vibration frame 4, thereby driving the grinding roller 12 and the turning roller 11 installed on the turning table 9 to reciprocate and vibrate in a direction perpendicular to the aluminum strip 3.

[0076] By changing the rotation speed in cycles, burrs and uneven defects can be removed more effectively, making the edge surface of the aluminum strip 3 smoother and flatter, thereby improving the finishing quality;

[0077] The reciprocating rotation of the grinding roller 12 and the turning roller 11 can process the edge of the aluminum strip 3 from different directions, avoiding the problems of lines and unevenness caused by single rotation processing, and further improving the surface quality of the edge of the aluminum strip 3;

[0078] The reciprocating vibration in the direction perpendicular to the aluminum strip 3 enables the grinding roller 12 and the turning roller 11 to contact the edge of the aluminum strip 3 more comprehensively, and can effectively process some tiny defects hidden inside the edge, thereby enhancing the finishing effect;

[0079] This complex motion mode can complete multiple processing operations in one processing process, reducing the processing steps and time, and improving the efficiency of the aluminum strip 3 edge finishing;

[0080] The pitch adjustment assembly includes a pitch adjustment screw 33 rotatably connected to the turning frame 7. A clamping motor is mounted on the side of the turning frame 7. The output shaft end of the clamping motor is fixedly connected to the pitch adjustment screw 33. The pitch adjustment screw 33 is provided with a forward thread segment and a reverse thread segment. The forward thread segment and the reverse thread segment are respectively connected to the two turning tables 9 in a transmission manner.

[0081] When performing edge finishing on aluminum strips 3 of different widths, the clamping motor on the side of the turning frame 7 is started, and the clamping motor drives the pitch-adjusting screw 33 to rotate. The forward and reverse thread segments on the pitch-adjusting screw 33 are respectively connected to the two turning tables 9. When the pitch-adjusting screw 33 rotates, the two turning tables 9 move closer to or further away from each other according to the rotation direction of the screw, thereby adjusting the distance between the two turning tables 9. This adjustable distance design enables the aluminum coil edge finishing mechanical device to adapt to the finishing requirements of aluminum strips 3 of different specifications, thereby improving the versatility and applicability of the device.

[0082] The tail of the base frame 1 is provided with a clamping and discharging system.

[0083] The clamping and discharging system includes a discharging motor 37 installed on the base frame 1 and two clamping racks 38 installed on the base frame 1. The output shaft end of the discharging motor 37 is connected to the fourth synchronous toothed belt, and the two shaping rollers 6 are connected to the fourth synchronous toothed belt. Two clamping rollers 39 are rotatably installed on each clamping rack 38. A gap for clamping and conveying the aluminum strip 3 is fixedly arranged between the two clamping rollers 39. Linking gears are installed on the two clamping rollers 39. The two linkage gears are connected in transmission. Multiple clamping rollers 39 are linked through the fifth synchronous toothed belt, and one clamping roller 39 is connected to the fourth synchronous toothed belt.

[0084] When the unwinding motor is working, the servo motor 17 works synchronously, and its output shaft end drives the two shaping rollers 6 to rotate through the fourth synchronous toothed belt, and also drives one of the pinch rollers 39 to rotate. The pinch roller 39 drives the other pinch rollers 39 to rotate through the fifth synchronous toothed belt. The interlocking gears on the pinch rollers 39 transmit to each other, ensuring the synchronization of the rotation of the pinch rollers 39. The gap between the two pinch rollers 39 clamps and conveys the aluminum strip 3, and the finished aluminum strip 3 is smoothly sent out of the device. This clamping and conveying method can ensure that the aluminum strip 3 will not deviate or relax during the discharge process, ensuring the stable quality of the finished aluminum strip 3;

[0085] The working principle and use process of the present invention:

[0086] When the aluminum coil edge finishing mechanical device of the present invention is working, the unwinding motor drives the unwinding roller 2 to rotate and release the aluminum strip 3. The aluminum strip 3 is fitted with the tensioning roller 32 after passing through the guide roller 15. The T-shaped guide rod 30 on the tensioning frame 29 of the tensioning system slides on the base frame 1. The tensioning spring 31 makes the tensioning roller 32 elastically tension the aluminum strip 3 to prevent the aluminum strip 3 from loosening and wrinkling, providing a stable foundation for subsequent processes. The servo motor 17 is started, and the first key shaft 18 at its output shaft end rotates, driving the first hollow shaft 21 to rotate, and the large-angle fan gear 24 and the small-angle fan gear 25 rotate accordingly. Due to the existence of the non-transmission section, they periodically engage and disengage with the differential gear 27 on the second hollow shaft 22, driving the second hollow shaft 22 to rotate, thereby rotating the longitudinal screw 23 and driving the finishing frame 5 to move back and forth along the axis direction of the unwinding roller 2;

[0087] At the same time, the second key shaft 19 drives the vertical screw 20 to rotate through the second synchronous toothed belt, so that the vertical vibration frame 4 moves back and forth in the vertical direction. The steering torsion spring 26 at the rotational connection between the vertical screw 20 and the base frame 1, and the longitudinal screw 23 and the vertical vibration frame 4 affects the displacement stroke and frequency, causing it to change cyclically. When the aluminum strip 3 passes through the shaping roller 6, the electric heating rod built into the shaping roller 6 and the electric heating block 16 in the trimming frame 5 are heated to 450°C to adjust the material properties of the aluminum strip 3. The shaping roller 6 made of stainless steel and with a length 1.4 times the width of the aluminum strip 3 shapes the entire width of the aluminum strip 3, eliminating minor deformations and unevenness, and providing a better foundation for turning and grinding;

[0088] The power system drives the reversing shaft 8 to rotate, which in turn drives the longitudinal screw 23 to rotate via the belt connecting section 35 and the elastic tensioning drive belt 36. The longitudinal screw 23 drives the grinding roller 12 to rotate via the third hollow shaft 34 and the second bevel gear. The grinding roller 12 drives the turning roller 11 to rotate via the first synchronous toothed belt. The turning tool 10 on the turning table 9 turns the edge of the aluminum strip 3. The turning roller 11 finely processes the turned surface. The wire brush on the grinding roller 12 polishes the surface to make the edge of the aluminum strip 3 smoother. The waste storage drawer 14 collects waste generated by turning and grinding.

[0089] Finally, the output shaft end of the servo motor 17 drives the two shaping rollers 6 to rotate through the fourth synchronous toothed belt, and at the same time drives a pinch roller 39 to rotate. The pinch roller 39 drives the other pinch rollers 39 to rotate through the fifth synchronous toothed belt. The interlocking gears on the pinch rollers 39 ensure the synchronization of rotation. The gap between the two pinch rollers 39 clamps and conveys the aluminum strip 3, and the finished aluminum strip 3 is smoothly sent out of the device.
