Description

Technical Field

[0001] This invention relates to the field of aluminum coil processing technology, specifically to a cutting and leveling device for color-coated aluminum coils. Background Technology

[0002] A slitting machine is a mechanical device used for uncoiling, leveling, and shearing metal coils. It mainly consists of an uncoiler, leveling rollers, a servo feeding system, and a shearing and stacking device. In practical applications, color-coated aluminum coils often need to be leveled and sheared by a slitting machine to cut the entire coil into a large number of aluminum sheets before they can be put into normal use.

[0003] Patent publication number CN119159379B relates to the field of aluminum single-panel processing technology. It includes a base, with a first vertical plate, a second vertical plate, a conveying device, and a placement box fixedly connected to the top of the base. The top of the base is equipped with a cutting mechanism, a flattening mechanism, and a first limiting mechanism. The top of the placement box is equipped with a second limiting mechanism. A folding rod is also provided on the top of the base. The cutting mechanism includes a first motor and a first rotating rod. The first motor is fixedly connected to the bottom of the folding rod, and the first rotating rod is fixedly connected to the output end of the first motor via a coupling. The first motor is used to drive the first rotating rod to rotate. A first gear and a second half gear are fixedly connected to the outer wall of the first rotating rod. This invention uses the reciprocating motion of the sliding sleeve to drive the cutting blade to reciprocate, enabling reciprocating cutting of the sheet metal, achieving automatic sheet metal cutting, and improving cutting efficiency.

[0004] The aforementioned patent utilizes the reciprocating motion of the sliding sleeve to drive the cutting blade in a reciprocating motion, enabling reciprocating cutting of the sheet metal and achieving automatic cutting, thus improving cutting efficiency. However, in practical use, while the existing patent can complete the conveying and cutting of aluminum sheets, it has significant shortcomings in terms of shearing fixation and sheet metal protection. Due to the lack of a clamping mechanism, the aluminum sheet is easily affected by the shearing impact force during cutting, resulting in vibration and burrs on the cut edge. Furthermore, the patent employs a unidirectional force shearing mode. When the aluminum sheet is solid below, the blade directly contacts the rigid table, easily causing chipping or curling; if the sheet is suspended below, the unidirectional shearing force forces the aluminum sheet to bend downwards, causing hidden damage to the surface coating or cross-sectional distortion. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for cutting and leveling color-coated aluminum coils, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a color-coated aluminum coil leveling and cutting device, comprising a leveling machine tool, wherein an arc-shaped support is fixedly installed at one end of the leveling machine tool, and the color-coated aluminum coil leveling and cutting device further comprises: The support frame is fixedly installed on the leveling machine tool; A cutting mechanism for cutting and transporting leveled aluminum plates is mounted on an arc-shaped support, which includes a blade holder that is slidably embedded in the arc-shaped support.

[0009] According to the above technical solution, multiple springs are installed between the fixing plate and the blade holder, the blade surfaces of the top cutter and the bottom cutter are parallel to each other and will not collide with each other when moving, and the transmission gear and the rack mesh with each other.

[0010] According to the above technical solution, the positioning mechanism includes a guide plate, a connecting rod, a slider, and a positioning plate. The guide plate is fixedly installed on one side of the arc-shaped support. The slider is slidably embedded in the guide plate. One end of the connecting rod is hinged to the fixed plate, and the other end is hinged to the slider. The positioning plate is slidably embedded at the bottom of the guide plate.

[0011] According to the above technical solution, the positioning mechanism further includes an elastic pull rod and a connecting rod II. The fixed end of the elastic pull rod is fixedly connected to the positioning plate, and one end of the connecting rod II is hinged to the slider I, and the other end is hinged to the elastic pull rod.

[0012] According to the above technical solution, the elastic tie rod is slidably embedded in the guide plate, and the connecting rod 2 slides on the top of the guide plate.

[0013] According to the above technical solution, the storage mechanism includes a storage box, a front baffle, a second slider, and a side baffle. The storage box is fixedly installed at the bottom of the arc-shaped support. The front baffle is rotatably installed on the storage box on the side away from the arc-shaped support. The second slider is slidably embedded in the bottom of the storage box. The side baffle is rotatably installed on the top of the second slider.

[0014] According to the above technical solution, the storage mechanism further includes a balancing plate, a limiting plate, and a fixing plate. The balancing plate is installed on the inner wall of the storage box, the front baffle, and the side baffle, respectively. The limiting plate is slidably embedded on the outer wall of the side baffle, and the fixing plate is slidably embedded on the outer wall of the side baffle.

[0015] According to the above technical solution, the storage box and the front baffle have a fixed slot, the balance plate is provided with a return torsion spring between the storage box, the front baffle and the side baffle, and the fixed insert plate is provided with a spring two between the front baffle and the storage box.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when shearing an aluminum plate, the blade holder is lowered, which drives the top cutter and the fixed plate to descend together. At the same time, the bottom cutter is driven to rise synchronously through engagement. When the fixed plate descends, the elastic pusher also descends and is pressed back into the fixed end when it contacts the ratchet. Due to the presence of the pawl, the ratchet will not rotate at this time. After the fixed plate fixes the aluminum plate, as the blade holder continues to descend, the top cutter and the bottom cutter cut the aluminum plate. After the cutting is completed, the blade holder is raised, and the fixed plate rises with it. When the fixed plate rises, the elastic pusher contacts the ratchet, and the ratchet rotates. The two rollers are driven to rotate through belt one and belt two to transport the cut aluminum plate. The aluminum plate is fixed by a fixing plate, which reduces the possibility of burrs caused by vibration during cutting. At the same time, the aluminum plate is cut by top and bottom cutters. This avoids the blade from colliding with the solid part of the aluminum plate and damaging it, and also avoids bending of the aluminum plate due to unidirectional processing when the bottom of the aluminum plate is hollow, which may affect the processing effect. Finally, after the cutter holder is lifted, the rollers will automatically transport the aluminum plate above forward, ensuring processing efficiency.

[0017] 2. In this invention, when the fixed plate descends, connecting rod one pushes slider one to slide along the guide plate. When slider one slides, it pulls connecting rod two, causing connecting rod two to move and drive the elastic pull rod to move towards the center of the guide plate. The elastic pull rod drives the positioning plate to move towards the center of the guide plate. After the positioning plate and the aluminum plate are in contact, the extended end of the elastic pull rod is pulled out as the pull rod two moves. When the fixed plate is raised, the extended end of the elastic pull rod first retracts into the fixed end, and then the positioning plate begins to reset. Before the positioning plate resets, the roller will move the aluminum plate forward. By positioning and limiting the movement space of the aluminum plate, the aluminum plate can be accurately placed into the storage box.

[0018] 3. In this invention, when the aluminum plate slides into the storage box, it first contacts the balancing plate on the side baffle, pressing the balancing plate into the side baffle. The side baffle adjusts the sliding angle of the aluminum plate and reduces the impact force when the aluminum plate slides down. Subsequently, the aluminum plate contacts the balancing plate on the front baffle and the storage box, making the aluminum plate parallel to the bottom of the storage box. In addition, lifting the limiting plate will automatically pop out the fixing plate, releasing it from the locking slot. The balancing plate enables quick collection and protection of the aluminum plate, while the limiting plate and fixing plate simplify the aluminum plate removal process. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 One embodiment of the present invention is: a color-coated aluminum coil leveling and cutting device, which includes a leveling machine tool 1, one end of which is fixedly mounted with an arc-shaped support 3, and the color-coated aluminum coil leveling and cutting device further includes: Support frame 2 is fixedly installed on the leveling machine tool 1 and support frame 2; in order to ensure the magnitude of the shearing force, a hydraulic device is also installed on the top of support frame 2.

[0022] A cutting mechanism for cutting and transporting leveled aluminum plates is installed on an arc-shaped support 3, which includes a blade holder 4 that is slidably embedded in the arc-shaped support 3. A positioning mechanism for positioning the cut aluminum plate is installed on the support frame 2. A storage mechanism for collecting the cut aluminum sheets is installed at the bottom of the support frame 2.

[0023] The cutting mechanism also includes a fixed plate 41, an L-shaped connecting block 42, an elastic push block 43, a ratchet 44, and a pawl 45. The fixed plate 41 is slidably embedded in the tool holder 4. The L-shaped connecting block 42 is fixedly installed on one side of the fixed plate 41. The elastic push block 43 is fixedly installed on the bottom of the L-shaped connecting block 42. The ratchet 44 is installed on the inner wall of the support frame 2, and the pawl 45 is installed on the inner wall of the support frame 2. The descent of the fixed plate 41 can drive the L-shaped connecting block 42 and the elastic push block 43 to descend together. At the same time, during the descent, because the protruding end of the elastic push block 43 is inclined, it will be pressed back to the fixed end when it touches the ratchet 44, and will pop out after moving away from the ratchet 44. Due to the obstruction of the pawl 45, the ratchet 44 will not rotate even if it comes into contact with the elastic push block 43 when it descends.

[0024] The cutting mechanism also includes a first belt 461, a second belt 462, a roller 47, a top cutter 481, a bottom cutter 482, a transmission gear 491, and a rack 492. The roller 47 is rotatably mounted on the arc-shaped support 3. One end of the first belt 461 is fitted onto the pawl 45, and the other end is fitted onto the roller 47. Both ends of the second belt 462 are respectively fitted onto the two rollers 47. The top cutter 481 is fixedly mounted on the bottom of the cutter holder 4, and the bottom cutter 482 is slidably embedded in the support frame 2. The transmission gear 491 is respectively mounted on the arc-shaped support 3 and the support frame 2, and the rack 492 is respectively mounted on the cutter holder 4 and the bottom cutter 482. When the elastic pusher 43 is lifted, its extended end contacts the ratchet 44, causing the ratchet 44 to rotate. This rotation, via belt 461 and belt 462, drives the roller 47 to rotate, causing the aluminum plate on the curved support 3 to move forward. Simultaneously, due to the presence of the transmission gear 491 and rack 492, the top cutter 481 and bottom cutter 482 always move synchronously in opposite directions. It should be noted that to ensure the proper functioning of belts 461 and 462, their wrap angle should not be less than 120°.

[0025] Multiple springs are installed between the fixed plate 41 and the blade holder 4. The blades of the top cutter 481 and the bottom cutter 482 are parallel to each other and will not collide with each other during movement. The transmission gear 491 and the rack 492 mesh with each other. The springs allow the blade holder 4 to continue to descend after the fixed plate 41 is in contact with the aluminum plate, so that the top cutter 481 can cut the aluminum plate. The bottom cutter 482 is designed to ensure that the top cutter 481 will not be damaged by the solid bottom of the aluminum plate or bend the aluminum plate by the groove bottom. Instead, the aluminum plate is cut by the parallel shearing of the top cutter 481 and the bottom cutter 482.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a color-coated aluminum coil cutting and leveling device further includes a positioning mechanism and a storage mechanism.

[0027] The positioning mechanism includes a guide plate 5, a connecting rod 51, a slider 52, and a positioning plate 53. The guide plate 5 is fixedly installed on one side of the arc-shaped support 3. The slider 52 is slidably embedded in the guide plate 5. One end of the connecting rod 51 is hinged to the fixed plate 41, and the other end is hinged to the slider 52. The positioning plate 53 is slidably embedded at the bottom of the guide plate 5.

[0028] The positioning mechanism also includes an elastic pull rod 54 and a connecting rod 55. The fixed end of the elastic pull rod 54 is fixedly connected to the positioning plate 53. One end of the connecting rod 55 is hinged to the slider 52, and the other end is hinged to the elastic pull rod 54. When the fixed plate 41 descends, the connecting rod 51 drives the slider 52 to descend along the guide plate 5. During the descent, the connecting rod 55 is pulled, which in turn drives the elastic pull rod 54, causing the elastic pull rod 54 to move the positioning plate 53. After the positioning plate 53 is in contact with the surface of the aluminum plate, as the fixed plate 41 descends, the connecting rod 55 pulls out the extended end of the elastic pull rod 54, thereby avoiding affecting the descent of the fixed plate 41.

[0029] The elastic tie rod 54 is slidably embedded in the guide plate 5, and the connecting rod 55 slides on the top of the guide plate 5.

[0030] The storage mechanism includes a storage box 6, a front baffle 61, a second slider 62, and a side baffle 63. The storage box 6 is fixedly installed at the bottom of the curved support 3. The front baffle 61 is rotatably installed on the side of the storage box 6 away from the curved support 3. The second slider 62 is slidably embedded in the bottom of the storage box 6, and the side baffle 63 is rotatably installed on the top of the second slider 62. The side baffle 63 can accommodate aluminum plates of different widths by adjusting the slider 62.

[0031] The storage mechanism also includes a balancing plate 64, a limiting plate 65, and a fixing plate 66. The balancing plate 64 is installed on the inner walls of the storage box 6, the front baffle 61, and the side baffle 63, respectively. The limiting plate 65 is slidably embedded in the outer wall of the side baffle 63, and the fixing plate 66 is slidably embedded in the outer wall of the side baffle 63. When the aluminum plate slides down to the top of the storage box 6, it will first contact the balancing plate 64 on the side baffles 63. As the balancing plate 64 is pressed into the side baffles 63, the angle of the aluminum plate is adjusted and the descent speed of the aluminum plate is slowed down, so as to prevent the aluminum plate above from damaging the surface of the stacked aluminum plates below due to the tilt angle and impact force.

[0032] The storage box 6 and the forward baffle 61 have fixing slots. A return torsion spring is provided between the balance plate 64 and the storage box 6, the forward baffle 61, and the side baffle 63. A second spring is provided between the fixing plate 66 and the forward baffle 61 and the storage box 6. The torsion springs allow the balance plate 64 to automatically pop out after the aluminum plate passes through, and the second spring allows the fixing plate 66 to automatically pop out after the limiting plate 65 is removed, facilitating the unfolding of the storage mechanism to remove the stacked aluminum plates.

[0033] Working principle: First, adjust the positions of the side baffles 63 according to the required width of the aluminum coil to be cut, and insert the fixing plate 66 into the corresponding fixing slot. Then, the limiting plate 65 falls naturally under gravity to limit the fixing plate 66. After the aluminum coil to be cut is leveled into an aluminum plate by the leveling machine 1, it is pushed to the bottom of the support frame 2 by the action of the leveling machine 1. The hydraulic mechanism at the top of the support frame 2 can lower the cutter 4 to cut the aluminum plate through the top cutter 481. The cutter 4 is fixed when it descends. Plate 41 descends and first contacts the aluminum plate with the top cutter 481. The pressure from the descending cutter holder 4 fixes the aluminum plate. Simultaneously, the pressure from the cutter holder 4 compresses the spring in both plates, allowing the cutter holder 4 to continue descending. As the fixed plate 41 descends, it drives the L-shaped connecting block 42, causing the elastic push block 43 to descend as well. When the elastic push block 43 descends, its protruding inclined surface contacts the ratchet 44, pressing it into the fixed end. At the same time, due to the presence of the pawl 45, the ratchet 44 will not rotate. Simultaneously, as the cutter holder 4 lowers the fixed plate 41, the hinged slider 52 of the connecting rod 51 begins to descend along the guide plate 5, driving the connecting rods 55 on both sides to pull the elastic pull rod 54 towards the center. The elastic pull rod 54 then drives the positioning plate 53 towards the center. When the positioning plate 53 contacts the aluminum plate, the extended end of the elastic pull rod 54 is pulled out until the fixed plate 41 contacts the aluminum plate.

[0034] After the fixing plate 41 fixes the aluminum plate, the blade holder 4 continues to descend. At this time, the top cutter 481 contacts the aluminum plate. In addition, as the blade holder 4 descends, the rack 492 on the blade holder 4 meshes with the transmission gear 491, which drives the rack 492 mounted on the bottom cutter 482, causing the bottom cutter 482 to rise as the blade holder 4 descends. After the top cutter 481 and the bottom cutter 482 simultaneously contact the aluminum plate, they both apply force to the aluminum plate as the blade holder 4 descends. Since the top cutter 481 and the bottom cutter 482 are parallel, the aluminum plate is subjected to shearing force, which avoids bending of the aluminum plate and avoids damage caused by the collision of the blades of the top cutter 481 and the bottom cutter 482.

[0035] After one cut is completed, the blade holder 4 is raised. As the blade holder 4 is raised, the spring 1 returns to its original position and then pulls up the fixing plate 41, causing the top cutter 481 and the bottom cutter 482 to return to their original positions. When the fixing plate 41 is raised, the slider 52 is reset via the connecting rod 51, causing the extended end of the elastic pull rod 54 to retract into the fixed section first, and then the fixed end is reset, which in turn drives the positioning plate 53 to reset. Before the positioning plate 53 is reset, the elastic push block 43 rises along with the fixed plate 41. Since the ratchet 44 is no longer blocked, the extended end of the elastic push block 43 pops out and drives the ratchet 44 to start rotating after contacting it. When the ratchet 44 rotates, the two rollers 47 are driven to rotate via the belt 461 and the belt 462, which transports the aluminum plate above the arc support 3 forward. At this time, the positioning plate 53 has not yet been reset, which restricts the movement of the aluminum plate, thereby achieving the positioning of the aluminum plate so that it can fall accurately into the storage box 6.

[0036] After the aluminum plate slides into the storage box 6, it first contacts the balancing plates 64 on the side baffles 63 and presses the balancing plates 64 into the side baffles 63. At this time, the impact force and angle of the aluminum plate falling are adjusted by the balancing plates 64 to prevent the aluminum plate from falling directly at a certain angle and damaging the aluminum plate below. As the aluminum plate continues to fall, the balancing plates 64 on the storage box 6 and the front baffle 61 guide the angle of the aluminum plate again, so that the aluminum plate falls into the storage box 6 in a state parallel to the bottom of the storage box 6, reducing damage to the storage box 6. After the plate is cut, the fixing plate 66 will automatically pop out of the fixing slot by lifting the limit plate 65 spring 2. At this time, the finished aluminum plate can be removed by simply rotating the side baffles 63 and the front baffle 61.
