[0032] In the related art, the metal coil may include a reel and a metal strip wound on the reel. The metal coil may include an aluminum foil coil, a tin foil coil, and the like.

[0033] In the process of tank container production, aluminum foil is needed to improve the anti-corrosion and thermal insulation performance of the tank container. In addition, the tank container needs to use aluminum foil with larger size and higher integrity, so as to improve the thermal insulation and anti-corrosion performance of the tank container.

[0034] In addition, the aluminum foil tape contains aluminum metal wire.

[0035] The present application provides an automatic processing device for metal sheets, which can unwind aluminum foil coils and process aluminum foil strips into aluminum foil sheets to improve processing accuracy, reduce processing time, ensure aluminum foil processing efficiency, and reduce safety hazards caused by manual participation.

[0036] In some embodiments, the automatic processing device for metal sheets can be applied to the processing of metal coils such as aluminum foil and tin foil.

[0037] Figure 1 It is a schematic structural diagram of the automatic processing device of the present invention.

[0038] See also Figure 1 The present application provides an automatic processing device for metal sheets (hereinafter referred to as the automatic processing device), which can unwind a coil and cut the unwinding metal strip into metal sheets to facilitate the subsequent use of the metal sheets.

[0039] The automatic processing device may include a carrying platform 100, an unwinding mechanism 200, a clamping mechanism 300 and a cutting mechanism 500. The carrying platform 100 is arranged on the working ground. The unwinding mechanism 200 is arranged outside the carrying platform 100 to carry and unwind the coil. The clamping mechanism 300 and the cutting mechanism 500 are arranged on the carrying platform 100, the clamping mechanism 300 is used to clamp the free end of the metal strip of the coil, and the cutting mechanism 500 is used to cut the metal strip into metal sheets.

[0041] Figure 2 yes Figure 1 An enlarged view of the structure at structure A shown in FIG.

[0042] See also Figure 1 and Figure 2 The present application provides an automatic processing device, which may include: a carrying platform 100, an unwinding mechanism 200, a clamping mechanism 300 and a cutting mechanism 500. The carrying platform 100 can be set on the working ground, and the carrying platform 100 can extend in the longitudinal direction. The unwinding mechanism 200 may include a support frame 210 and a plurality of rollers 220. The support frame 210 can be set on the working ground and close to one end of the longitudinal direction of the carrying platform 100. The plurality of rollers 220 are arranged at intervals in the longitudinal direction, and the rollers 220 extend in the transverse direction. The plurality of rollers 220 can be rotatably connected to the upper part of the support frame 210 around their own rotation axis. The plurality of rollers 220 can jointly form an arc-shaped supporting surface with a downward concave middle portion, and the arc-shaped supporting surface can carry the coil. The clamping mechanism 300 is disposed on the carrier platform 100 so as to be reciprocatingly movable in the longitudinal direction. The clamping mechanism 300 is used to clamp the free end of the metal strip of the coil so as to drive the free end away from the coiling mechanism 200 and make the coil roll and unwind on the unwinding mechanism 200. The cutting mechanism 500 can be disposed on one end of the carrier platform 100 close to the unwinding mechanism 200. The cutting mechanism 500 can cut the metal strip clamped by the clamping mechanism 300.

[0043] When the staff processes the coil by the automatic processing device, the coil is placed on the unwinding mechanism 200 , and then the free end of the metal strip on the coil is limited on the clamping mechanism 300 .

[0044] After the free end of the metal strip is limited to the clamping mechanism 300, the clamping mechanism 300 can clamp the free end and move away from the unwinding mechanism 200 in the longitudinal direction, and the coiled material rolls and unwinds on the arc-shaped support surface. The clamping mechanism 300 stops after moving a preset distance, and the cutting mechanism 500 cuts the metal strip clamped by the clamping mechanism 300 to cut the metal strip into a metal sheet.

[0045] After the metal strip is cut, the clamping mechanism 300 releases the metal sheet so that the metal sheet falls onto the carrying platform 100. Afterwards, the clamping mechanism 300 can move toward the cutting mechanism 500 to continue clamping the free end of the metal strip on the coil, thereby achieving multiple cutting of the coil. The unwinding mechanism 200 on the automatic processing device can quickly place the coil on the unwinding mechanism 200, and can ensure that the coil is continuously and stably unwound, effectively avoiding the problems of unsmooth discharge, movement, and breakage of the material. In addition, the automation of the various functional components of the automatic processing device effectively improves the production efficiency of the metal sheet, ensures the processing accuracy of the metal sheet, and reduces the safety hazards caused by manual participation.

[0046] Figure 3 It is a schematic structural diagram of the automatic processing device of the present invention from a horizontal perspective.

[0047] See also Figures 1 to 3 In this embodiment, the carrying platform 100 extends in the longitudinal direction. The carrying platform 100 may include a platform frame 110 and a carrying plate 120. The platform frame 110 may be a frame structure, so as to reduce the weight of the carrying platform 100 while ensuring the structural strength of the carrying platform 100, so as to facilitate the movement of the carrying platform 100. The carrying plate 120 may extend in the longitudinal direction. The carrying plate 120 is disposed on the upper side of the platform frame 110 to carry the metal sheet formed after the metal strip is cut.

[0048] In some embodiments, two clamping movable guide rails 130 may be further provided on the platform frame 110. The two clamping movable guide rails 130 may be respectively located on the lateral sides of the carrier plate 120. The clamping movable guide rails 130 extend longitudinally. The clamping mechanism 300 is provided on the clamping movable guide rails 130, and the clamping mechanism 300 can reciprocate longitudinally on the clamping guide rails, thereby improving the stability, reliability and safety of the clamping mechanism 300 when moving, and improving the cutting accuracy of the metal sheet.

[0049] See also Figures 1 to 3 In this embodiment, the unwinding mechanism 200 is used to support the coil. The coil can be rolled and limited on the unwinding mechanism 200 to ensure the stability of the coil when unwinding, and to prevent the coil from rolling out of the unwinding mechanism 200, effectively avoiding the problems of unsmooth unwinding, movement and breakage.

[0050] The unwinding mechanism 200 may include a support frame 210 and a plurality of rollers 220. The support frame 210 may be disposed at one end of the longitudinal direction of the carrying platform 100. The plurality of rollers 220 may be rotatably limited to the upper portion of the support frame 210. The plurality of rollers 220 may form a downwardly concave arc-shaped support surface for supporting the coil, and allow the coil to roll in the arc-shaped support surface, so that the coil can be continuously rolled and unwound, thereby ensuring the unwinding efficiency of the coil, improving the stability of the unwinding of the coil, preventing the coil from moving, and improving the processing efficiency of the metal sheet.

[0051] See also Figures 1 to 3 In this embodiment, the support frame 210 may include a support frame body 211 and two limit plates 212. The support frame body 211 may be set on a working surface. The two limit plates 212 may be spaced apart at two lateral sides of the support frame body 211, and the two limit plates 212 extend longitudinally. The two limit plates 212 may each be provided with a plurality of relatively disposed slots 2121, and the plurality of slots 2121 on the two limit plates 212 are respectively used to engage and limit the two ends of the plurality of rollers 220.

[0052] A plurality of relatively arranged slots 2121 are provided on the two limit plates 212 for accommodating the two ends of a plurality of rollers 220 respectively. On the one hand, it is convenient for installing, disassembling and repairing the rollers 220. On the other hand, it is convenient for the unwinding mechanism 200 to selectively install different numbers of rollers 220 according to the type, shape, unwinding speed, etc. of the coil, thereby improving the convenience of the unwinding mechanism 200.

[0053] In some embodiments, the support frame 211 can be fixedly connected to the supporting frame to ensure the spacing and relative position between the support frame 211 and the supporting frame, thereby preventing the unwinding mechanism 200 from being skewed relative to the supporting platform 100, ensuring that the coil is unrolled stably and reliably, preventing the coil from moving during unwinding, and ensuring the cutting efficiency of the metal coil.

[0054] See also Figures 1 to 3 In this embodiment, the two limit plates 212 can be fixedly connected to the support frame 211. The upper end of the limit plate 212 is provided with a plurality of downwardly concave slots 2121. In a plane perpendicular to the horizontal direction, the bottom projections of the plurality of slots 2121 on the limit plate 212 are all located on a downwardly concave arc track. Therefore, after the plurality of rollers 220 are accommodated in the plurality of slots 2121 on the limit plate 212, the plurality of rollers 220 form a downwardly concave arc support surface.

[0055] In some embodiments, in a plane perpendicular to the horizontal direction, the shape of the bottom of the multiple slots 2121 in the limit plate 212 can be adapted to the shape of the end of the roller 220, so that after the roller 220 is accommodated in the slot 2121, the roller 220 can rotate around its own rotation axis, and can prevent the roller 220 from jumping vertically or deviating longitudinally in the slot 2121, so as to ensure the stability and reliability of the roller 220 during rotation, thereby ensuring the stability of the coil when unwinding.

[0056] See also Figures 1 to 3 In this embodiment, the upper parts of the two limit plates 212 can extend upward beyond the roller 220. The upper parts of the two limit plates 212 can respectively abut the lateral sides of the coil, so that the rotation axis of the coil is parallel to the rotation axis of the roller 220, thereby preventing the coil from moving or deflecting when unwinding, so that the coil can be unwound continuously and stably, and the coil cutting efficiency is improved.

[0057] In some embodiments, the upper portions of the two limiting plates 212 can extend upward beyond the adjacent rollers 220 to facilitate installation and removal of the rollers 220 .

[0058] See also Figure 2 In this embodiment, the roller 220 may include a roller shaft 221 and a rolling body 222. Both ends of the roller shaft 221 are engaged in the slot 2121, so that the roller shaft 221 is stably limited on the limiting plate 212. The rolling body 222 is rotatably sleeved on the roller shaft 221, so that the rolling body 222 can rotate around the axis of the roller shaft 221. When the roller 220 carries the coil, the coil is supported on the rolling body 222. When the coil is unrolled, the coil rotates around its own rotation axis and can roll on the arc-shaped support surface. The rolling body 222 rotates around the axis of the roller shaft 221, thereby realizing stable and reliable unwinding of the coil and preventing the coil from being deflected and stuck.

[0059] In some embodiments, in a plane perpendicular to the horizontal direction, the cross-sections at both ends of the roller 221 may be rectangular, star-shaped, triangular, or other structures, so that the roller 221 can be stably and reliably limited in the slot 2121 of the limiting plate 212 to prevent the roller 221 from rolling or jumping, and to prevent the roller 220 from affecting the unwinding of the coil.

[0060] In other embodiments, in a plane perpendicular to the horizontal direction, the cross section of the end of the roller shaft 221 may also be an ellipse. In other embodiments, in a plane perpendicular to the horizontal direction, the cross section of the end of the roller shaft 221 may also be an irregular shape, so that the roller shaft 221 can be stably engaged with the limiting plate 212.

[0061] See also Figures 1 to 3In this embodiment, a plurality of rollers 220 can form a downwardly concave arc-shaped support surface. When the staff places the coil on the unwinding mechanism 200 or the coil is unwinding, the coil is in a semi-free state. The coil can roll toward the bottom of the arc-shaped support surface under its own gravity. The limit plate 212 can abut against the lateral side walls of the coil to adapt to the arc-shaped support surface and guide the coil so that the rotation axis of the coil is parallel to the rotation axis of the roller 220, thereby preventing the coil from deflecting when rolling and unwinding, solving the problem of material jamming and unsmooth material discharge, improving the efficiency of coil discharge and unwinding, and ensuring the processing efficiency of metal sheets.

[0062] In some embodiments, the arc-shaped support surface may be a symmetrical structure. The plurality of rollers 220 are arranged symmetrically relative to the center line extending laterally from the arc-shaped support surface, so as to facilitate placing the coil on the arc-shaped support surface, effectively prevent the coil from rolling to the outside of the arc-shaped support surface, and improve the stability and reliability of the unwinding mechanism 200.

[0063] In some embodiments, ten rollers 220 may be disposed on the support frame 210. The ten rollers 220 may be symmetrically arranged along a center line extending laterally along the arc-shaped support surface to ensure that the coil can be stably and continuously unrolled.

[0064] In other embodiments, four, six, eight or twelve rollers 220 may be provided on the support frame 210 so that the coil is finally located at the bottom of the arc-shaped support surface after rolling, thereby improving the reliability and safety of the coil and preventing the coil from getting stuck.

[0065] In some embodiments, nine rollers 220 may be provided on the support frame 210. The nine rollers 220 may be arranged symmetrically along the center line extending laterally along the arc-shaped support surface, wherein the rotation axis of one roller 220 is located on the center line of the arc-shaped support surface, and the other eight rollers 220 are symmetrically arranged along the center line extending laterally, so as to ensure that the coil can be stably and continuously unwound.

[0066] In other embodiments, three, five, seven or eleven rollers 220 may be provided on the support frame 210 so that the coil is finally located at the bottom of the arc-shaped support surface after rolling, thereby improving the reliability and safety of the coil and preventing the coil from getting stuck.

[0067] In other embodiments, the arcuate support surface may be an asymmetric structure, so that the coil is unloaded onto the arcuate support surface or rolled on the arcuate support surface to unwind, and the coil eventually rolls to the bottom of the arcuate support surface, preventing the coil from rolling to the outside of the unwinding mechanism 200.

[0068] See also Figures 1 to 3In this embodiment, the distance between any two adjacent rollers 220 is smaller than the diameter of the reel. When the metal strip on the coil is used up, the reel is prevented from falling into the support frame 210 through the gap between the two adjacent rollers 220, thereby facilitating the replacement of the coil and improving the processing efficiency of the metal sheet.

[0069] See also Figures 1 to 3 In this embodiment, in a plane perpendicular to the horizontal direction, the arc length of the projection of the arc trajectory can be greater than 1 / 3 of the circumference of the outer circumference of the coil, so that when the staff releases the material onto the arc support surface or the coil is unrolled and rolled, the coil can be prevented from rolling to the outside of the arc support surface, thereby ensuring the stability and reliability of the coil when unrolling, and preventing the coil from rolling to the outside and crushing the staff.

[0071] See also Figure 1 , Figures 3 to 5 In this embodiment, the clamping mechanism 300 may include two clamping seats 310, a clamping connecting rod 320 and a plurality of clamping claws 330. The two clamping seats 310 may be respectively arranged on the lateral sides of the carrying platform 100, and the clamping seats 310 may be able to move back and forth longitudinally on the carrying platform 100. The clamping connecting rod 320 may extend in the lateral direction. The two ends of the clamping connecting rod 320 may be fixedly connected to the two clamping seats 310, respectively. A plurality of clamping claws 330 may be arranged on the clamping connecting rod 320 at intervals in the lateral direction, and the clamping claws 330 may open and close to clamp the free end, so that the free end may move away from the rolling mechanism 200 following the two clamping seats 310.

[0072] When the coil is placed on the unwinding mechanism 200, the free end of the coil moves toward the clamping mechanism 300 and is restrained on the plurality of clamping claws 330. The two clamping seats 310 can move synchronously along the longitudinal direction on the carrying platform 100 to drive the clamping connecting rod 320, the plurality of clamping claws 330 and the free end to move away from the unwinding mechanism 200 at the same time.

[0073] See also Figure 1 , Figures 3 to 5In this embodiment, the two clamping seats 310 are movably disposed on the lateral sides of the platform frame 110 and are located outside the carrier plate 120. The two clamping seats 310 can move laterally on the platform frame 110 so that the metal strip is located above the carrier plate 120. When the cutting mechanism 500 cuts the metal strip into metal sheets, the metal sheets fall onto the carrier plate 120, so that multiple metal sheets can be stacked and placed, and it is convenient for the staff to move the stacked multiple metal sheets at the same time, thereby improving the use efficiency of the metal sheets.

[0074] In some embodiments, the two clamping seats 310 are slidably disposed on the two clamping movable guide rails 130 , respectively, so as to ensure the stability, reliability and safety of the movement of the clamping seats 310 and improve the cutting accuracy of the metal sheet.

[0075] In some embodiments, multiple clamps 330 are disposed on the clamping connecting rod 320, and, in a plane perpendicular to the vertical direction, the projections of the multiple clamps 330 are located within the enclosed range of the supporting plate 120, so that the multiple clamps 330 can clamp the free ends of the metal strips and facilitate the metal sheets to fall onto the supporting plate 120.

[0076] In this embodiment, the clamp 330 can be an electric clamp 330 or a pneumatic clamp 330, so that the clamp 330 can be closed to clamp the free end of the metal strip, and can also be opened to loosen the free end of the metal strip, thereby facilitating the clamping mechanism 300 to reciprocately clamp the free end of the metal strip to achieve cyclic cutting of the metal strip.

[0077] In some embodiments, the plurality of clamping jaws 330 may be nine clamping jaws 330 , and the nine clamping jaws 330 are arranged on the clamping connecting rod 320 at intervals in the transverse direction to improve the connection strength between the clamping mechanism 300 and the free end of the metal strip.

[0078] In other embodiments, for coils of different axial lengths, the nine clamping jaws 330 can be selectively opened and closed, so that part of the clamping jaws 330 relative to the coil is opened and closed, and the other part of the clamping jaws 330 is stopped, thereby reducing the use cost of the clamping mechanism 300.

[0079] In other embodiments, the plurality of clamping jaws 330 may be two, three, five, six, seven or eight clamping jaws 330 , so long as the free end of the metal strip can be clamped stably and reliably.

[0080] In some embodiments, multiple clamping jaws 330 are movably disposed on the clamping connecting rod 320 in the transverse direction, so that the multiple clamping jaws 330 can move to different positions for coils of different axial lengths, thereby improving the clamping stability and reliability of the clamping mechanism 300.

[0081] In other embodiments, a tension adjustment member (not shown in the figure) is further provided between the clamping jaw 330 and the clamping connecting rod 320 to facilitate real-time adjustment of the relative position of the clamping jaw 330 and the clamping connecting rod 320 .

Figure 8 yes Figure 7 Schematic diagram of part of the structure of DD. Fig. 9 It is one of the structural schematic diagrams of the longitudinal perspective of the automatic processing device of the present invention.

[0083] See also Figures 4 to 9 In this embodiment, the automatic processing device may further include a clamping drive mechanism 400. The clamping drive mechanism 400 may include a clamping driver 410, a synchronous rotating shaft 430 and two transmission belts 440. The clamping driver 410 may be arranged at the lower part of the carrying platform 100 so as to be able to output a driving force. The synchronous rotating shaft 430 is transmission-connected to the clamping driver 410, and the two ends of the synchronous rotating shaft 430 are transmission-connected to the two transmission belts 440 respectively so as to be able to drive the two transmission belts 440 to rotate synchronously. The two transmission belts 440 extend in the longitudinal direction, and the two transmission belts 440 are transmission-connected to the two clamping seats 310 respectively so as to enable the two clamping seats 310 to move synchronously.

[0084] In some embodiments, the clamping drive 410 may be an electric motor. In other embodiments, the clamping drive 410 may be a servo motor.

[0085] In some embodiments, a differential 420 may be provided between the clamping driver 410 and the synchronous shaft 430 to control the rotation speed of the synchronous shaft 430 , thereby controlling the translation speed of the clamping mechanism 300 in the longitudinal direction.

[0086] See also Figure 4 , Figures 7 to 9 In this embodiment, the synchronous shaft 430 is rotatably connected to the lower side of the platform frame 110. The synchronous shaft 430 extends in the lateral direction, so that the lateral ends of the synchronous shaft 430 are respectively connected to the two transmission belts 440, thereby driving the two transmission belts 440 to rotate synchronously.

[0087] See also Figure 4 , Figures 7 to 9 In this embodiment, the two transmission belts 440 are respectively located at the lower side of the platform frame 110 and at the lateral sides of the platform frame 110. The two transmission belts 440 are respectively connected to the two clamping seats 310 to drive the two clamping seats 310 to reciprocate on the two clamping moving guide rails 130, thereby improving the cutting accuracy and cutting efficiency of the metal sheet.

[0088] The transmission belt 440 may include two end shafts 441 and a transmission belt body 442. The two end shafts 441 are arranged at intervals in the longitudinal direction, and the two end shafts 441 extend in the transverse direction so that the two end shafts 441 can rotate around their own rotation axis. The end shafts 441 on the same side of the two transmission belts 440 in the longitudinal direction are transmission-connected to the synchronous shaft 430. The transmission belt body 442 is rotatably sleeved outside the two end shafts 441 so as to rotate with the end shafts 441.

[0089] The clamping driver 410 can drive the one end shaft 441 of the two transmission belts 440 to rotate through the synchronous shaft 430, so that the transmission belt body 442 rotates around the two end shafts 441, so that the transmission belt 440 can drive the clamping mechanism 300 to approach the cutting mechanism 500 and clamp the free end of the metal belt, and the transmission belt 440 can drive the clamping mechanism 300 away from the cutting mechanism 500, so as to facilitate the unwinding of the coil and the cutting mechanism 500 to cut the metal belt, thereby improving the production efficiency of the metal sheet.

[0090] In some embodiments, the transmission belt body 442 is fixedly connected to the clamping seat 310 so that when the transmission belt body 442 rotates around the two end shafts 441, it can drive the clamping seat 310 to move longitudinally to facilitate multiple clamping of the free end of the metal belt.

[0091] In some embodiments, the clamping drive mechanism 400 is disposed close to the cutting mechanism 500 to facilitate the arrangement of circuits inside the automatic processing device and to facilitate the maintenance and inspection of the clamping drive mechanism 400 by the staff.

[0092] In some embodiments, the clamping drive mechanism 400 may further include a distance sensor (not shown in the figure), which can detect the rotation distance of the transmission belt body 442 so as to obtain the longitudinal movement distance of the clamping seat 310, thereby facilitating the automatic processing device to process metal sheets of different lengths and improve the production efficiency of the product.

[0093] In some embodiments, the distance sensor may be a laser distance sensor, an ultrasonic distance sensor, an infrared distance sensor, or the like.

[0094] In other embodiments, the distance sensor can also directly obtain the moving distance of the moving seat in the longitudinal direction, so as to realize the processing and production of metal sheets of different lengths.

[0095] Fig.10 It is another structural schematic diagram of the longitudinal perspective of the automatic processing device of the present invention.

[0096] See also Figure 1 , Figure 4 , Figure 6 and Fig.10 In this embodiment, the cutting mechanism 500 may include a base 510, a connecting frame 520, an auxiliary clamping structure 540 and a cutter 560. The base 510 is connected to one end of the carrying platform 100 close to the unwinding mechanism 200, and the base 510 is used to carry the metal strip. The connecting frame 520 can be connected to the carrying platform 100. The connecting frame 520 and the upper surface of the base 510 are arranged vertically to form a passage gap 530, and the passage gap 530 is used for the passage of the metal strip. The auxiliary clamping structure 540 is connected to the connecting frame 520 in a movably manner, and the auxiliary clamping structure 540 can move toward the base 510 to press the metal strip on the base 510. The cutter 560 is movably arranged on the connecting frame 520 in the horizontal direction to be able to cut the metal strip into metal sheets.

[0097] After the clamping claw 330 in the clamping mechanism 300 clamps the free end, the clamping driver 410 can drive the clamping seat 310 to move away from the unwinding mechanism 200 through the transmission belt 440 to unwind the coil, and part of the metal strip of the coil passes through the passage gap 530 to move away from the unwinding mechanism 200.

[0098] When the clamping seat 310 clamps the free end away from the rolling mechanism 200 and moves a preset distance, the clamping driver 410 stops running, so that the clamping seat 310 stops on the clamping moving guide rail 130. The auxiliary pressing structure 540 moves toward the base 510 to press and limit part of the metal roll on the base 510.

[0099] Afterwards, the cutter 560 moves in the transverse direction to cut the metal strip into metal sheets, thereby effectively improving the cutting efficiency and cutting accuracy of the coiled material and improving the production efficiency of the metal sheets.

[0100] The end of the metal sheet close to the cutting mechanism 500 first falls onto the carrier plate 120. After one end of the metal sheet falls onto the carrier plate 120, the clamping jaw 330 releases the other end of the metal sheet so that the other end of the metal sheet falls evenly onto the carrier plate 120, thereby preventing the metal sheet from wrinkling and facilitating subsequent use of the metal sheet.

[0101] See also Figure 1 , Figure 4 , Figure 6 and Fig.10 In this embodiment, the base 510 is fixedly connected to the platform frame 110 and is located at one end of the carrier plate 120 facing the unwinding mechanism 200 to ensure the stability of the base 510 and thus ensure the cutting accuracy of the cutter 560 .

[0102] See also Figure 1 , Figure 3 and Figure 4In this embodiment, in the vertical direction, the upper surface of the base 510 is higher than the arc-shaped supporting surface of the unwinding mechanism 200, so that the metal strip is pressed on the base 510, and when the auxiliary clamping structure 540 clamps the metal strip, the auxiliary clamping structure 540 will not cause the coil to unwind, thereby ensuring the cutting size accuracy of the metal sheet.

[0103] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 and Fig.10 In this embodiment, the connecting frame 520 may include two connecting seats 521 and a connecting frame body 522. The two connecting seats 521 may be located on both sides of the base 510 in the horizontal direction. The two connecting seats 521 extend vertically, and the lower ends of the connecting seats 521 may be fixedly connected to the platform frame 110 to ensure the stability of the connecting seats 521. The connecting frame body 522 extends horizontally, and the two ends of the connecting frame body 522 are fixedly connected to the upper ends of the connecting seats 521. The connecting frame body 522 is located above the base 510, so that a passage gap 530 is formed between the connecting frame body 522 and the base 510, and the passage gap 530 is used for the free end of the metal belt to pass through, so as to facilitate the free end of the metal belt to be limited on the clamping claw 330.

[0104] In some embodiments, the connection seat 521 and the connection frame body 522 are both frame structures, so as to reduce the weight of the connection frame 520 while ensuring the structural strength of the connection seat 521 and the connection frame body 522, and facilitate the installation, disassembly and maintenance of the cutter 560 and the auxiliary clamping structure 540.

[0105] See also Figure 3 , Figure 4 , Figure 6 , Fig. 9 and Fig.10 In this embodiment, the auxiliary clamping structure 540 is movably disposed on the connecting frame 522, and the auxiliary clamping structure 540 can move toward the base 510 to press and limit the metal strip on the base 510, thereby facilitating the cutter 560 to cut the metal strip.

[0106] The auxiliary clamping structure 540 may include a clamping plate 541, a lifting guide column 542 and a lifting driver 543. The clamping plate 541 extends in the transverse direction. The clamping plate 541 is located in the passage space 530 above the base 510. The upper end of the lifting guide column 542 is lifted and disposed on the connecting frame 522, and the lower end of the lifting guide column 542 is connected to the clamping plate 541, so that the lifting guide column 542 can stably and reliably guide the lifting of the clamping plate 541, thereby improving the lifting accuracy of the clamping plate 541. The lifting driver 543 is disposed on the connecting frame 522, and the lifting end of the lifting driver 543 is fixedly connected to the clamping plate 541, so as to be able to drive the clamping plate 541 to lift and lower.

[0107] In some embodiments, the length of the pressing plate 541 along the lateral direction is greater than or equal to the length of the metal strip along the lateral direction, so that the metal strip can be completely pressed on the base 510 to ensure the cutting accuracy and cutting efficiency of the cutter 560. In other embodiments, the length of the metal strip along the lateral direction is less than or equal to the length of the base 510 along the lateral direction.

[0108] In other embodiments, there may be a plurality of lifting guide pillars 542 , and the plurality of lifting guide pillars 542 are disposed at intervals on the connecting frame 522 to further improve the stability and reliability of the auxiliary pressing structure 540 .

[0109] In other embodiments, there may be multiple lifting drivers 543 , and the multiple lifting drivers 543 are spaced apart on the connecting frame 522 to improve the lifting efficiency of the clamping plate 541 and ensure the lifting safety and reliability of the clamping plate 541 .

[0110] In some embodiments, the lifting driver 543 may be a lifting cylinder, the cylinder body of which is connected to the connecting frame 522, and the lifting end of which is connected to the pressing plate 541 to drive the pressing plate 541 to move up and down.

[0111] In other embodiments, the lifting driver 543 may also be a lifting screw rod, a lifting chain or other structures, so that the pressing plate 541 can be lifted or lowered relative to the connecting frame 522 .

[0112] In some embodiments, the cutter 560 is located on the side of the connecting frame 520 away from the unwinding mechanism 200, and the cutter 560 and the base 510 are arranged at intervals along the longitudinal direction, so that after the cutter 560 cuts the metal strip, the clamping mechanism 300 can move longitudinally to approach the base 510 and clamp the free end of the metal strip on the base 510, thereby facilitating the reciprocating cutting of the metal strip, reducing manual participation, improving the degree of automation, and improving the processing efficiency of the metal sheet.

[0113] In some embodiments, the cutter 560 may be a cutting saw or a laser cutter.

[0114] See also Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 In this embodiment, the cutting mechanism 500 may further include a cutting guide rail 550 and a cutting drive structure 570. The cutting guide rail 550 may be disposed on the connecting frame 520. The cutting guide rail 550 is located above the passage interval 530. The cutting guide rail 550 extends in the transverse direction. The cutter 560 is movably connected to the cutting guide rail 550 so that the cutter 560 can cut the metal strip into metal sheets in the transverse direction. The cutting drive structure 570 is transmission-connected to the cutter 560 so that the cutter 560 can move in the transverse direction on the cutting guide rail 550.

[0115] When the clamping mechanism 300 clamps the free end away from the winding mechanism 200, the lifting end of the lifting driver 543 drives the clamping plate 541 to move toward the base 510 to hold the metal strip and limit it on the base 510. The cutting drive structure 570 drives the cutter 560 to move on the cutting guide rail 550 to move from one side of the metal strip to the other side in the horizontal direction, thereby cutting the metal strip into metal sheets. The clamping mechanism 300 cooperates with the auxiliary limiting mechanism to prevent the vibration amplitude and frequency of the metal strip during the cutting process, thereby effectively ensuring that the cutting marks of the metal sheet are smooth, the cutting accuracy is high, the cutting efficiency is high, and the safety hazards caused by manual participation can be reduced.

[0116] In some embodiments, there may be multiple cutting guide rails 550. The multiple cutting guide rails 550 may be respectively connected to a side wall of the connecting frame 522 that is longitudinally away from the unwinding mechanism 200, and may also be respectively connected to a side wall of the two connecting seats 521 that is longitudinally away from the unwinding mechanism 200. The multiple cutting guide rails 550 can improve the stability and reliability of the cutter 560 when it moves in the lateral direction, and ensure the cutting efficiency and cutting accuracy of the cutter 560.

[0117] See also Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 In this embodiment, the cutting drive structure 570 is disposed on the connecting frame 520 to be in driving connection with the cutter 560, so as to drive the cutter 560 to move back and forth in the lateral direction. The cutting drive structure 570 can refer to the structural arrangement of the transmission belt 440 described above.

[0118] The cutting drive structure 570 may include two cutting rollers 571, a cutting belt body 572 and a cutting driver 573. The two cutting rollers 571 are respectively arranged on the two connecting seats 521. The rotation axes of the two cutting rollers 571 extend longitudinally, and the two cutting rollers 571 can rotate around their own rotation axes. The cutting belt body 572 is sleeved on the two cutting rollers 571 so that the cutting belt body 572 can rotate with the two cutting rollers 571. The cutting belt body 572 is connected to the cutter 560 so that the cutting belt body 572 reciprocates and drives the cutter 560 to reciprocate. The cutting driver 573 is arranged on the connecting frame 520, and the cutting driver 573 is transmission-connected with the cutting roller 571 so as to drive the cutting belt body 572 to rotate, thereby driving the cutter 560 to reciprocate.

[0119] In some embodiments, the cutting drive structure 570 does not need to include the cutting roller 571 and the cutting belt body 572. The cutting drive structure 570 may include a cutting drive 573. The cutting drive 573 is disposed on the cutter 560. A gear is disposed on the driving end of the cutting drive 573. A rack is disposed on the cutting guide rail 550. The gear can be threadedly connected to the rack to drive the cutter 560 to reciprocate on the cutting guide rail 550.

[0120] In other embodiments, the cutting drive structure 570 does not need to include the cutting roller 571 and the cutting belt body 572. The cutting drive structure 570 may also include a cutting driver 573 and a transmission screw. The cutting driver 573 is threadedly connected to the transmission screw. The transmission screw is rotatably arranged on the connecting frame 520, and the transmission screw passes through the cutter 560 and is threadedly connected to the cutter 560, so that when the transmission screw rotates around its own rotation axis, the cutter 560 can be driven to reciprocate on the cutting guide rail 550.

[0121] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0122] In some other embodiments, the cutting drive structure 570 can also be applied to the transmission belt 440 mentioned above.

[0123] See also Figure 1 , Figure 3 , Figure 4 and Fig.10In this embodiment, the automatic processing device may further include a guide mechanism 600. The guide mechanism 600 may include two guide plates 610 and a plurality of guide rollers 620. The two guide plates 610 are arranged on one end wall of the carrying platform 100 facing the unwinding mechanism 200, and the two guide plates 610 are arranged in a lateral interval. The plurality of guide rollers 620 are rotatably connected between the two guide plates 610, and the rotation axes of the plurality of guide rollers 620 are parallel to the rotation axis of the supporting roller 220. The plurality of guide rollers 620 together form an arc-shaped guide surface protruding upward, and the uppermost end of the arc-shaped guide surface is flush with the upper surface of the base 510. The arc-shaped guide surface can guide the metal strip to pass through the passage interval 530 and then be connected to the clamping mechanism 300, and can prevent the surface of the metal strip from scratching the base 510 during the unwinding process of the coil, thereby protecting the surface quality of the metal strip and preventing the metal strip from being scratched.

[0124] In other embodiments, the guide plate 610 extends in the longitudinal direction. A first guide roller 620, a second guide roller 620 and a third guide roller 620, all extending in the transverse direction, may be included between the two guide plates 610. The first guide roller 620, the second guide roller 620 and the third guide roller 620 are arranged in sequence in the longitudinal direction. The first guide roller 620 and the second guide roller 620 are located at the same vertical height. The third guide roller 620 is arranged close to the unwinding mechanism 200, and in the vertical direction, the second guide roller 620 is higher than the third guide roller 620, and the third guide roller 620 is higher than the arc-shaped supporting surface, so that after the metal belt is successively attached to the outer sides of the third guide roller 620, the second guide roller 620, and the first guide roller 620, the free end passes through the passage gap 530 and is limited on the clamp 330, so as to increase the tension of the metal belt, thereby ensuring the taut state of the metal belt when the auxiliary clamping structure 540 clamps the metal belt, facilitating efficient cutting by the cutter, improving the cutting accuracy of the cutter 560, and ensuring the smoothness of the cutting marks of the metal sheet.

[0125] In some embodiments, the structure of the guide roller 620 can be set with reference to the structure of the support roller 220 .

[0126] In some embodiments, the guide roller 620 may include a roller shaft 221 and a rolling body 222. The two ends of the roller shaft 221 are respectively fixed on the two guide plates 610. The rolling body 222 is rollably mounted on the roller shaft so that the rolling body 222 can rotate around the roller shaft under the friction force of the metal belt.

[0127] In some embodiments, the uppermost end of the arc-shaped guide surface, the upper surface of the base 510 and the clamping jaw 330 are located in the same longitudinal plane, so that after being guided by the arc-shaped guide surface, the metal strip moves longitudinally to the upper surface of the base 510 and finally moves to the clamping jaw 330, thereby ensuring the stability of the metal strip. When the coil is unrolled, the free end moves, the auxiliary clamping structure 540 clamps, and the cutter 560 cuts, the metal strip will not vibrate in the up and down directions, thereby ensuring the cutting accuracy of the cutter 560.

[0128] In some embodiments, the guide mechanism 600 may include a guide roller 620 to bend the metal strip and fit it to a portion of the guide roller 620 , so that after the metal strip passes through the guide roller 620 , it is located in the same longitudinal plane as the upper surface of the base 510 and the clamp 330 .

[0129] In this embodiment, the automatic processing device may further include a holding frame (not shown in the figure). The holding frame may include two rotating rods and a holding roller that can rotate around its own rotation axis. One end of the two rotating rods is rotatably connected to the opposite sides of the two guide plates 610, and the other end of the two rotating rods is rotatably connected to the two ends of the holding roller, and the rotation axis of the holding roller is parallel to the rotation axis of the guide roller 620. The holding roller can rotate around the rotation axis of the rotating rod to between the guide mechanism 600 and the unwinding mechanism 200 to hold the metal strip.

[0130] After the free end of the coil is guided by the arc-shaped guide surface, it passes through the passage gap 530 and is confined in the clamping claw 330. The holding frame can rotate downward around the rotation axis of the rotating rod under the action of its own gravity, so that the holding roller is pressed on the upper surface of the metal belt, so that when the clamping mechanism 300 clamps the free end and moves away from the coiling mechanism 200, the tension of the metal belt is increased, so that the metal belt is in a taut state, so that the cutting accuracy and cutting efficiency of the metal belt can be improved after the auxiliary pressing structure 540 presses the metal belt, and the quality of the cut metal sheet can be improved.

[0131] In some embodiments, the structure of the holding roller can refer to the structure of the above-mentioned roller 220. The holding roller can include a roller shaft 221 and a rolling body 222. The roller shaft 221 is fixedly connected to the rotating rod, and the rolling body 222 can be rotatably sleeved on the roller shaft to be able to hold the metal strip and move relative to the metal strip.

[0132] In this embodiment, the automatic processing device may further include a controller. The controller may be electrically connected to the clamping jaws 330, the clamping driver 410, the differential 420, the lifting driver 543, and the cutting driver 573, so that the staff can control the opening and closing of the clamping jaws 330, the start and stop of the clamping driver 410, the speed change of the differential 420, the start and stop of the lifting driver 543, the start and stop of the cutting driver 573, etc. through the controller.

[0133] In some embodiments, the controller can also control the output speed, running time, etc. of the clamping driver 410. In other embodiments, the controller can also adjust the preset distance of movement of the clamping mechanism 300, so as to adjust the size of the metal sheet. In other embodiments, the controller can also control the output speed, running time, etc. of the cutting driver 573, so as to control the moving speed of the cutter 560 in the lateral direction.

[0134] In some embodiments, the controller can also be electrically connected to the cutter 560 to control the cutting speed of the cutter 560. In other embodiments, when the cutter 560 is a cutting saw, the controller can control the rotation speed of the cutting saw, thereby controlling the cutting speed of the cutting saw.

[0135] See also Figures 1 to 10 The present application provides an automatic processing device for metal sheets. When the staff processes the coiled material through the automatic processing device, the coiled material is first placed on the unwinding mechanism 200. When the coiled material falls onto the arc-shaped support surface of the unwinding mechanism 200, the coiled material rolls on the arc-shaped support surface under the guidance of its own gravity and the limit plate 212, and finally stops at the bottom of the arc-shaped support surface. The unwinding process is fast and efficient, and can effectively prevent the problems of the coiled material being stuck, moving, and breaking during the unwinding process.

[0136] After the coil stops on the arc-shaped support surface, the free end of the coil is moved to the arc-shaped guide surface, and then the free end passes through the passage gap 530 and is limited in the plurality of clamping claws 330. Afterwards, the clamping driver 410 drives the transmission belt 440 to rotate through the synchronous shaft 430, thereby driving the clamping seat 310 to move away from the base 510 in the longitudinal direction, and the free end follows the clamping seat 310 to move away from the base 510, and the coil rolls on the unwinding mechanism 200 to unwind.

[0137] When the clamping mechanism 300 is away from the base 510, the clamping driver 410 stops running, and the clamping mechanism 300 and the free end stop on the clamping rail. Afterwards, the lifting driver 543 drives the pressing plate 541 to move toward the base 510 to press and limit the metal strip on the base 510, so that part of the metal strip is limited between the clamping mechanism 300 and the cutting mechanism 500.

[0138] After the metal strip is partially limited between the clamping mechanism 300 and the cutting mechanism 500, the cutting driver 573 drives the cutting mechanism to move on the cutting guide rail 550 to cut the metal strip into metal sheets. After the metal strip is cut into metal sheets, one end of the metal sheet close to the base 510 first falls onto the carrier plate 120, and then the clamping jaw 330 releases the other end of the metal sheet so that the other end of the metal sheet falls onto the carrier plate 120, thereby facilitating the flat placement of the metal sheet.

[0139] Afterwards, the clamping driver 410 is turned on, and the clamping driver 410 moves the clamping seat 310 toward the base through the transmission belt 440, so that the clamping claw 330 continues to clamp the free end of the coil. The lifting driver 543 controls the pressing plate 541 to move away from the base 510, so that the clamping mechanism 300 clamps the free end away from the cutting mechanism 500, thereby realizing multiple cutting of the coil, so as to improve the production efficiency of the metal sheet, ensure the processing accuracy of the metal sheet, and reduce the safety hazards caused by manual participation.

[0140] The present application also provides an automatic processing method for metal sheets, which is applied to any of the above automatic processing devices, so as to achieve. The automatic processing method includes: Step S110 , placing the coil on the arc-shaped support surface of the unwinding mechanism 200 with its axis in the horizontal direction, and rolling the coil to the bottom of the arc-shaped support surface.

[0141] Step S120 , passing the free end of the coil through the cutting mechanism 500 .

[0142] In step S130 , the clamping mechanism 300 clamps the free end of the coil.

[0143] In step S210, the clamping mechanism 300 moves in a longitudinal direction away from the rolling mechanism 200, driving the free end to move away from the rolling mechanism 200, and the coil rolls on the arc-shaped supporting surface.

[0144] In step S220 , the clamping mechanism 300 moves to a preset distance and then stops, and the cutting mechanism 500 cuts the metal strip.

[0145] When the coil needs to be processed, the coil is placed on the arc-shaped support surface of the unwinding mechanism 200 with its axis extending in the transverse direction. The coil rolls on the arc-shaped support surface and finally rolls to the bottom of the arc-shaped support surface.

[0146] After the staff passes the free end of the coil through the cutting mechanism 500, the clamping mechanism 300 clamps the free end of the coil. The clamping mechanism 300 moves away from the coiling mechanism 200 in the longitudinal direction, and the free end follows the clamping mechanism 300 to move in the longitudinal direction, and the coil rolls on the arc-shaped support surface to unwind. When the coil rolls on the arc-shaped support surface to unwind, the unwinding mechanism 200 can effectively prevent the coil from deflecting and jamming, and can prevent the coil from moving and breaking, thereby improving the efficiency of coil processing and preventing the occurrence of safety hazards.

[0147] When the clamping mechanism 300 moves a preset distance in the longitudinal direction and stops, the cutting mechanism 500 cuts the metal strip into metal sheets to improve the processing accuracy and processing efficiency of the metal sheets. Afterwards, the clamping mechanism 300 releases the metal sheets to make the metal sheets fall onto the carrying platform 100.

[0148] The clamping mechanism 300 moves longitudinally toward the cutting mechanism 500 to continue clamping the free end of the coil, thereby enabling reciprocating cutting of the coil and improving the processing efficiency of the coil.

[0149] In this embodiment, the automatic processing method may further include: In step S230 , after the cutting mechanism 500 cuts the metal strip, the clamping mechanism 300 releases the metal sheet and can move longitudinally toward the unwinding mechanism 200 to continue clamping the free end of the coil.

[0150] After releasing the metal sheet, the clamping mechanism 300 moves toward the unwinding mechanism 200 to continue clamping the free end of the coil, thereby enabling reciprocating cutting of the coil and improving the processing efficiency of the coil.

[0151] In this embodiment, the cutting mechanism 500 includes a base 510, a connecting frame 520, an auxiliary pressing structure 540 and a cutter 560. The automatic processing method may also include: In step S221 , after the clamping mechanism 300 moves away from the rolling mechanism 200 by a preset distance in the longitudinal direction, the auxiliary pressing structure 540 moves toward the base 510 to press the metal strip on the base 510 ; the cutter 560 moves in the transverse direction to cut the metal strip into metal sheets.

[0152] The auxiliary pressing structure 540 presses the metal strip onto the base 510, and the cutter 560 moves in the lateral direction to cut the metal strip into metal sheets. Part of the metal strip is limited in the clamping mechanism 300 and the cutting mechanism 500, so as to ensure the reliability of the cutter 560 in the process of cutting the metal strip, improve the smoothness of the cutting marks, and ensure the cutting accuracy and cutting efficiency of the metal sheets.
