Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-8 The present application provides a technical solution: an automatic feeding device for an uncoiler, comprising a body 1, a discharging assembly 2 is arranged on one side of the body 1, a mounting plate 3 is fixedly connected to the front side of the body 1, a first support 4 is fixedly connected to the top of the mounting plate 3 near one side of the discharging assembly 2, a dust collection assembly 5 is arranged at the bottom of the first support 4, the dust collection assembly 5 comprises an electric push rod 501 fixedly installed below the first support 4, a fixed frame 502 is fixedly connected to the output end of the electric push rod 501, a dust collection pipe 503 is arranged at the bottom of the fixed frame 502, a dust collection frame 505 is fixedly connected to one side of the first support 4, a connecting pipe 504 is fixedly connected between the dust collection frame 505 and the fixed frame 502, an exhaust fan 506 is installed in the dust collection frame 505, and an air outlet 507 is formed in one side of the dust collection frame 505.

[0029] When the unwinding assembly 2 unwinds the coiled material, the laser thickness gauge 604 detects the thickness of the coiled material, and the data of the thickness of the coiled material is transmitted to remotely start the electric push rod 501, and the output end of the electric push rod 501 can drive the fixed frame 502 to move up and down, so as to adjust the distance between the dust collection pipe 503 and the surface of the coiled material. When the fixed frame 502 moves, the placement block 601, the placement plate 602 and the scraping brush 603 can move up and down. When the scraping brush 603 contacts the coiled material, it can scrape off the dust and impurities on the surface of the coiled material. Then, the air extractor 506 is remotely started to generate negative pressure, and the dust on the surface of the coiled material is sucked into the inside of the fixed frame 502 through the connecting pipe 504, and finally enters the inside of the dust collection box 505, thereby achieving the effect of collecting dust.

[0030] It should be noted that the unwinding assembly 2 is equivalent to the coiled material bearing mechanism in the existing conventional uncoiler, including an inflatable reel for fixing the center hole of the coiled material, a driving device for providing power, etc.

[0031] It should be noted that the laser thickness gauge 604 and the first visual detection sensor 605 are both prior art. The laser thickness gauge 604 emits laser and receives reflected light, and calculates the thickness of the coiled material by measuring the flight time or phase difference of the laser.

[0033] The remote start first motor 8, the output end of the first motor 8 can drive the first threaded rod 9 to rotate, the first threaded rod 9 can drive the externally fixed first pulley 10 to rotate, the first pulley 10, the belt body 11 and the second pulley 12 drive the second threaded rod 13 to rotate, and the connecting frame 14 connected with the first threaded rod 9 and the second threaded rod 13 can move up and down, so as to adjust the height of the tensioning roller 15, and then change the tension of the coiled material.

[0034] As shown in Figure 6 , Figure 7 The connecting frame 14 is provided with a correction assembly 17 on both sides, the correction assembly 17 comprises two groups of fixed frames 1701 fixedly connected with the connecting frame 14, one side of the two groups of fixed frames 1701 is fixedly installed with a gas cylinder 1702, the output end of the gas cylinder 1702 is fixedly connected with a connecting frame 1703, and the inside of the connecting frame 1703 is bearing-connected with a guide roller 1704.

[0035] During the tension conveying process of the coiled material, the remote control gas cylinder 1702 is started, so that the output end of the gas cylinder 1702 drives the guide roller 1704 to move, and then the position of the guide roller 1704 is adjusted, so that the edge of the coiled material is in contact with the outer surface of the guide roller 1704, thereby preventing the coiled material from deviating during the conveying process.

[0036] As shown in Figure 8 The first support plate 18 is fixedly connected with the first support plate 18, and the second support plate 19 is provided above the first support plate 18. The top of the first support plate 18 and the bottom of the second support plate 19 are both provided with a placing groove 20. The hydraulic cylinder 21 is installed in the placing groove 20 on the top of the first support plate 18. The output end of the hydraulic cylinder 21 is fixedly connected with the placing groove 20 at the bottom of the second support plate 19. The first support plate 18 and the second support plate 19 are both provided with two groups of second motors 22. The output ends of the two groups of second motors 22 are connected with the flattening rollers 23. The first support plate 18 and the second support plate 19 are both provided with two groups of flattening rollers 23, which are respectively arranged between the first support plate 18 and the second support plate 19. The first support plate 18 is fixedly installed with a second visual detection sensor 24, and the other side of the machine body 1 is provided with a straightening device 25.

[0037] Remote start hydraulic cylinder 21, hydraulic cylinder 21 drive second support plate 19 up and down, adjust the distance between the two groups of flattening roller 23, to adapt to different thickness of the coil, remote start second motor 22, the output end of the second motor 22 can drive the flattening roller 23 rotation, thereby flattening the coil, to achieve the preliminary straightening, straightening device 25 can further accurate straightening of the coil after preliminary straightening, and then eliminate the coil due to the deformation caused by curl, essentially is to the open after the coil shape correction, for the coil shape and surface state adjustment and recovery, let it from the uneven state, such as curl, wave, warping, make it to the required flatness and shape accuracy.

[0038] Need to be added, straightening device 25 belongs to the existing technology of curved coil leveling mechanism, including multiple groups of straightening roller group, roller gap adjusting mechanism, driving mechanism and guide mechanism, by the driving mechanism of multiple groups of roller, the coil is applied to the continuous bending extrusion force, the internal fiber length of the material inside tends to be consistent, finally realize the open flat.

[0039] Working principle: the feeding assembly 2 feeds the coiled material, which is the starting point of uncoiling. The feeding assembly 2 serves as the initial bearing and releasing device of the coiled material, and is responsible for the preliminary unwinding of the coiled raw material. The laser thickness gauge 604 is used to detect the thickness value of the coiled material. When the coiled material with large thickness is fed, the remote control electric push rod 501 retracts, so that the fixed frame 502 drives the scraping assembly 6 to move upwards, reducing the excessive friction of the scraping brush 603 on the surface of the coiled material to prevent scratches. When the coiled material with small thickness is fed, the remote control electric push rod 501 extends, so that the fixed frame 502 drives the scraping assembly 6 to move downwards, increasing the friction of the scraping brush 603 on the surface of the coiled material to prevent dust and debris from adhering to the surface of the coiled material. Then, the suction fan 506 is started to generate negative pressure, so that the dust is sucked into the dust collection frame 505. After the coiled material cleaning is completed, the tensioning structure is entered. The first motor 8 is started by remote control. After the first motor 8 is started, the first threaded rod 9, the first belt pulley 10, the belt body 11, the second belt pulley 12 and the second threaded rod 13 are rotated, driving the tensioning roller 15 to move up and down, adjusting the tensioning pressure, avoiding the relaxation, wrinkles or excessive stretching of the coiled material during unwinding, ensuring that the coiled material is "smoothly unwound" from the coiled material in a stable state, meeting the requirements of the uncoiler for "continuous and uniform feeding". Then, the unwound coiled material enters the preliminary straightening assembly 17. The cylinder 1702 drives the guide roller 1704 to move, so that the edge of the coiled material is in close contact with the guide roller 1704, thereby realizing the effect of preventing deviation and ensuring the accuracy of the uncoiling direction. According to the thickness of the coiled material measured by the laser thickness gauge 604, the distance between the first support plate 18 and the second support plate 19 is adjusted by remotely starting the hydraulic cylinder 21, thereby adjusting the distance between the flattening rollers 23. Finally, the coiled material is accurately straightened by the straightening device 25, thereby eliminating the deformation of the coiled material caused by curling. In essence, it is a "morphological correction" of the coiled material after uncoiling. The coiled material changes from a state of curling, waving, warping and other irregularities to a flat state that meets the production requirements, ensuring that the uncoiled material meets the subsequent processing requirements, which belongs to the extension and optimization of the uncoiling process.

[0040] Specifically, in the control system, the normal value of the thickness of the coiled material is D monitored by the laser thickness gauge 604. The initial tensioning pressure of the pressure sensor 16 at the tensioning roller 15 is P. The second visual detection sensor 24 is used to monitor the surface conveying condition of the coiled material, and the surface of the coiled material is detected by the first visual detection sensor 605 to have a normal value of a of the surface scratch area.

[0041] It should be noted that the normal value of the scratch area a is generally caused by the presence of dust, fibers and other impurities in the environment during the feeding process, which adhere to the surface of the coiled material or contact components and are crushed or rubbed during the conveying process, forming scratches or being in contact with other hard objects during the feeding process, causing scratches.

[0042] If the coil thickness value is monitored in real time by the laser thickness gauge 604, the value D1>D, and the tension roller 15 is monitored in real time by the pressure sensor 16, the tension pressure value is P1>P, if the coil surface appears slight stretch lines at this time, the second visual detection sensor 24 can capture the lines through high-definition imaging, and compare with the normal coil surface image through the preset image processing algorithm, and then identify the abnormal stretch line features, which indicates that the tension force is too large at this time, the coil is stretched too much, and long-term operation may cause the coil thickness to thin or risk of rupture, so the tension pressure should be reduced at this time;

[0043] If the coil surface scratch area value is a1>a at this time, the first visual detection sensor 605 can detect, and the inkjet marker in the control system can be used to spray ink on the scratch to mark the scratch;

[0044] It should be noted that the inkjet marker is a prior art and will not be described in detail here;

[0045] If the marked coil area is unwound and flattened by the tension structure and the flattening structure, and the second visual detection sensor 24 detects the unwound coil scratch area value, if the marked scratch area value is a2, a

[0046] If the marked coil scratch area value after unwinding is a2, 2a

[0047] Specifically, the first motor 8 is started remotely to rotate in the forward direction, so that the output end of the first motor 8 drives the first threaded rod 9 and the first pulley 10 to rotate, the first pulley 10 drives the belt body 11, the second pulley 12, and the second threaded rod 13 to rotate, so that the connecting frame 14 connected with the first threaded rod 9 and the second threaded rod 13 moves downward, and the tension pressure value is controlled in the range of ≤P, and then the tension pressure is accurately controlled to protect the coil;

[0048] If the pressure is reduced to ≤P, and the real-time state of the coil is still in the curved deformation state, and the thickness value D1D detected by the second visual detection sensor 24 at this time, it can be left for a period of time to observe whether the coil recovers from the deformation, if it recovers from the deformation and becomes flat, and the thickness value D1≤D at this time, it indicates that the coil can recover from the deformation in the tension pressure value P1>P range, but has hysteresis, the tension pressure value is at the critical value, and the coil quality is good;

[0049] If the pressure drops to ≤P, the remote hydraulic cylinder 21 is started, the output end of the hydraulic cylinder 21 is retracted, the distance between the first support plate 18 and the second support plate 19 is reduced, and the flattening pressure is increased.

[0050] If the local protruding coil is subjected to secondary flattening, the local protruding stress is easily dispersed, causing the coil to bend, at which time a period of time is needed to stand by, if the coil is restored to be flat, it indicates that the coil restores the deformation, if the coil is still in a bent state, the flattening operation can be performed again until the coil is restored to be flat;

[0051] After a period of time, if the deformation is still not restored and the coil still appears local bending, and the thickness value D1 < D, it indicates that the coil is damaged in the tension pressure value P1 > P range and cannot restore the deformation, the tension pressure value P1 needs to be included in the control range to prevent subsequent coils from being damaged.

[0052] Further, if the coil flattening operation is completed at this time, the local protrusion appears on the surface of the coil through the second visual detection sensor 24, it indicates that the thickness D1 > D of the coil at this time is larger, because the thicker coil has stronger resistance to compression, it needs larger pressure to flatten it, so the distance between the two groups of flattening rollers 23 is larger, and the pressure between the current flattening rollers 23 is smaller, which cannot adapt to the flattening requirement of the thicker coil;

[0053] It should be noted that the thicker coil needs larger flattening force to overcome the rigidity of the material to make the surface flat.

[0054] If the thickness value of the coil is monitored by the laser thickness gauge 604 in real time D2 < D, and the tension pressure is monitored in real time P2 < P, if the coil surface is subjected to flattening operation by the flattening roller 23, and the second visual detection sensor 24 detects that the coil surface appears wrinkles, it indicates that the tension pressure value is too small, and the coil conveying stability is poor;

[0055] Specifically, the first motor 8 is remotely started in reverse rotation, so that the output end of the first motor 8 drives the first threaded rod 9 and the first belt pulley 10 to rotate, the first belt pulley 10 drives the belt body 11, the second belt pulley 12 and the second threaded rod 13 to rotate, so that the connecting frame 14 which is threadedly connected with the first threaded rod 9 and the second threaded rod 13 moves upward, controls the tension pressure value in the range of ≥P, avoids the coil from further relaxing, and remotely controls the driving assembly in the discharging assembly 2 to operate in reverse, so that the coil is wound in reverse, and then the coil is conveyed in forward direction, so that the coil with surface wrinkles is tensioned and output again, and then the flattening operation is performed again;

[0056] If the control tensioning pressure value is controlled in the range of P, the coil material may be over-stretched to produce plastic deformation, and if the tensioning pressure disappears, the coil material may quickly rebound to form new wrinkles. At this time, if the coil material recovers the deformation, it indicates that the coil material quality is high, and if it cannot recover the deformation, it indicates that the coil material is permanently deformed.

[0057] Further, if the coil flattening operation is completed at this time, the surface of the coil material has a pressure mark through the second visual detection sensor 24, which can be judged whether the coil material is too thin and the pressure of the flattening roller 23 is too large, resulting in a pressure mark on the surface of the coil material. At this time, the hydraulic cylinder 21 should be remotely started, and the output end of the hydraulic cylinder 21 is extended to increase the distance between the first support plate 18 and the second support plate 19, thereby reducing the flattening pressure.

[0058] If the pressure mark still exists after the flattening operation, it can be checked by manual inspection whether the flattening roller 23 is insufficient in strength due to long-term use, and the roller body can be replaced.

[0059] The roughness detector can also be used to detect the outer surface of the roller body to check whether the surface of the flattening roller 23 is scratched, corroded, or attached with hard particles due to long-term use, thereby causing damage to the surface of the coil material.

[0060] It should be noted that the thinner coil material has weak deformation resistance, and excessive pressure will leave an unrecoverable pressure mark on the surface. Therefore, the flattening pressure should be dynamically adjusted according to the real-time data of the laser thickness gauge 604 to accurately flatten the coil material of different thicknesses, and to correct the shape of the coil material after uncoiling. The coil material is in a state of curling, waving, warping, etc. to achieve the required flatness and shape accuracy, and to ensure that the uncoiled material meets the subsequent processing requirements.
