[0034] In the related art, a metal coil may include a reel and a metal strip wound around the reel. The metal coil may include an aluminum foil coil, a tin foil coil, etc.

[0035] In the production process of a tank container, it is necessary to use aluminum foil to improve the anti-corrosion performance and heat preservation performance of the tank container. Moreover, the tank container needs to use aluminum foil with a relatively large size and high integrity, so as to improve the heat preservation performance and anti-corrosion performance of the tank container.

[0036] Moreover, the aluminum foil strip contains aluminum metal wires. Compared with the tin foil strip, the cutting process of the aluminum foil strip is more difficult and the processing accuracy is lower, resulting in a lower production efficiency of the aluminum foil sheet, a higher production cost, and affecting the subsequent production efficiency of the tank container.

[0037] The present application provides an automatic processing device for metal sheets, which can unroll an aluminum foil coil and process the aluminum foil strip into an aluminum foil sheet to improve the processing accuracy, reduce the processing time, ensure the aluminum foil processing efficiency, and reduce the potential safety hazards caused by manual participation.

[0038] 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.

[0039] Figure 1 is a schematic structural diagram of the automatic processing device of the present invention.

[0040] Refer to Figure 1 , the present application provides an automatic processing device for metal sheets (hereinafter simply referred to as the automatic processing device), which can unroll the coil and cut the unrolled metal strip into metal sheets for the subsequent use of the metal sheets.

[0041] The automatic processing device may include a carrying platform 100, an uncoiling mechanism 200, a clamping mechanism 300, and a cutting mechanism 500. The carrying platform 100 is disposed on the working ground. The uncoiling mechanism 200 is disposed outside the carrying platform 100 for carrying and uncoiling the coil material. The clamping mechanism 300 and the cutting mechanism 500 are disposed on the carrying platform 100. The clamping mechanism 300 is used for clamping the free end of the metal strip of the coil material, and the cutting mechanism 500 is used for cutting the metal strip into metal flakes.

[0042] Refer to Figure 1 , for the convenience of understanding and description, the direction of the carrying platform 100 relative to the working ground is defined as the upper direction in the following text, and the direction away from the upper direction is defined as the lower direction in the following text. This up-and-down direction is the vertical direction; the relative direction between the carrying platform 100 and the uncoiling mechanism 200 is defined as the longitudinal direction in the following text; the direction perpendicular to the vertical direction and the longitudinal direction is defined as the transverse direction in the following text.

[0043] Figure 2 is Figure 1 the enlarged view of the structure at position A in the structure shown in

[0044] Refer to Figure 1 and Figure 2 , this application provides an automatic processing device, which may include: a carrying platform 100, an uncoiling mechanism 200, a clamping mechanism 300, and a cutting mechanism 500. The carrying platform 100 may be disposed on the working ground, and the carrying platform 100 may extend longitudinally. The uncoiling mechanism 200 may include a support frame 210 and a plurality of rollers 220. The support frame 210 may be disposed on the working ground and near one longitudinal end of the carrying platform 100. The plurality of rollers 220 are arranged at intervals longitudinally, and the rollers 220 extend transversely. The plurality of rollers 220 are all rotatably connected to the upper part of the support frame 210 around their own rotation axes. The plurality of rollers 220 may jointly form an arc-shaped support surface with a downward depression in the middle, and the arc-shaped support surface can carry the coil material. The clamping mechanism 300 is disposed on the carrying platform 100 so as to be reciprocally movable longitudinally. The clamping mechanism 300 is used for clamping the free end of the metal strip of the coil material to be able to drive the free end away from the uncoiling mechanism 200 and cause the coil material to roll and uncoil on the uncoiling mechanism 200. The cutting mechanism 500 may be disposed at one end of the carrying platform 100 close to the uncoiling mechanism 200, and the cutting mechanism 500 can cut the metal strip clamped by the clamping mechanism 300.

[0045] When the staff processes the coil material through the automatic processing device, the coil material is placed on the uncoiling mechanism 200, and then the free end of the metal strip on the coil material is limited on the clamping mechanism 300.

[0046] After the free end of the metal strip is limited behind the clamping mechanism 300, the clamping mechanism 300 can clamp the free end and move longitudinally away from the uncoiling mechanism 200, and the coil is uncoiled by rolling on the arc-shaped supporting surface. After the clamping mechanism 300 moves a preset distance and stops, the cutting mechanism 500 cuts the metal strip clamped by the clamping mechanism 300 to cut off the metal strip to form metal sheets.

[0047] After the metal strip is cut, the clamping mechanism 300 releases the metal sheet so that the metal sheet falls onto the bearing platform 100. Then, the clamping mechanism 300 can move towards the cutting mechanism 500 to continue clamping the free end of the metal strip on the coil, thereby realizing multiple cuts of the coil. The uncoiling mechanism 200 on the automatic processing device can quickly place the coil on the uncoiling mechanism 200 and can ensure continuous and stable uncoiling of the coil, effectively avoiding problems such as unsmooth feeding, crosstalk, and material breakage. Moreover, the automation of each functional component of the automatic processing device effectively improves the production efficiency of the metal sheet, ensures the processing accuracy of the metal sheet, and reduces potential safety hazards caused by manual participation.

[0048] Figure 3 It is a schematic structural diagram of the automatic processing device of the present invention from a lateral perspective.

[0049] Refer to Figures 1 to 3 In this embodiment, the bearing platform 100 extends longitudinally. The bearing platform 100 may include a platform frame 110 and a bearing plate 120. The platform frame 110 may be a frame structure to reduce the weight of the bearing platform 100 while ensuring the structural strength of the bearing platform 100, facilitating the movement of the bearing platform 100. The bearing plate 120 may extend longitudinally. The bearing plate 120 is disposed on the upper side of the platform frame 110 for bearing the metal sheets formed after the metal strip is cut.

[0050] In some embodiments, two clamping movement guide rails 130 may also be provided on the platform frame 110. The two clamping movement guide rails 130 may be respectively located on the lateral sides of the bearing plate 120. The clamping movement guide rails 130 extend longitudinally. The clamping mechanism 300 is disposed on the clamping movement 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 movement of the clamping mechanism 300 and improving the cutting accuracy of the metal sheet.

[0051] Refer to Figures 1 to 3 In this embodiment, the uncoiling mechanism 200 is used to support the coil. The coil is rotatably limited on the uncoiling mechanism 200 to ensure the stability of the coil during uncoiling and to prevent the coil from rolling out of the uncoiling mechanism 200, effectively avoiding problems such as unsmooth feeding, crosstalk, and material breakage.

[0052] 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 longitudinal end of the loading platform 100. The plurality of rollers 220 are rotatably limited to the upper part of the support frame 210. The plurality of rollers 220 can form a downwardly concave arc-shaped support surface for supporting the coil, enabling the coil to roll within the arc-shaped support surface, so that the coil can continuously unwind, ensuring the unwinding efficiency of the coil, improving the stability of coil unwinding, preventing the coil from shifting, and improving the processing efficiency of the metal sheet.

[0053] Refer to Figures 1 to 3 , in this embodiment, the support frame 210 may include a support frame body 211 and two limiting plates 212. The support frame body 211 may be disposed on the working ground. The two limiting plates 212 may be spaced apart on the transverse sides of the support frame body 211, and both the two limiting plates 212 extend longitudinally. A plurality of oppositely arranged card slots 2121 may be formed on both the two limiting plates 212, and the plurality of card slots 2121 on the two limiting plates 212 are respectively used for clamping and limiting the two ends of the plurality of rollers 220.

[0054] A plurality of oppositely arranged card slots 2121 are formed on the two limiting plates 212 for respectively accommodating the two ends of the plurality of rollers 220. On the one hand, it facilitates the installation, disassembly, and maintenance of the rollers 220. On the other hand, it also enables the unwinding mechanism 200 to selectively install different numbers of rollers 220 according to the type, size, unwinding speed, etc. of the coil, improving the convenience of the unwinding mechanism 200.

[0055] In some embodiments, the support frame body 211 may be fixedly connected to the load-bearing frame to ensure the spacing and relative position between the support frame body 211 and the load-bearing frame, thereby preventing the unwinding mechanism 200 from tilting relative to the loading platform 100, ensuring stable and reliable unwinding of the coil, preventing the coil from shifting during unwinding, and ensuring the cutting efficiency of the metal coil.

[0056] Refer to Figures 1 to 3 , in this embodiment, the two limiting plates 212 may be fixedly connected to the support frame body 211. A plurality of downwardly concave card slots 2121 are formed at the upper ends of the limiting plates 212. In a plane perpendicular to the transverse direction, the bottom projections of the plurality of card slots 2121 on the limiting plates 212 are all located on a downwardly concave arc-shaped track. Thus, after the plurality of card slots 2121 on the limiting plates 212 accommodate the plurality of rollers 220, the plurality of rollers 220 form a downwardly concave arc-shaped support surface.

[0057] In some embodiments, in a plane perpendicular to the lateral direction, the shape of the bottoms of the multiple card slots 2121 in the limit plate 212 can be set to match the shape of the end of the idler roller 220, so that after the idler roller 220 is received in the card slot 2121, the idler roller 220 can rotate around its own rotation axis, and moreover, the idler roller 220 can be prevented from jumping vertically or deflecting longitudinally in the card slot 2121, so as to ensure the stability and reliability of the idler roller 220 during rotation, and thus ensure the stability during the uncoiling of the coil material.

[0058] Refer to Figures 1 to 3 , in this embodiment, the upper parts of the two limit plates 212 can extend upward beyond the idler roller 220. The upper parts of the two limit plates 212 can respectively abut against the two lateral sides of the coil material, so that the rotation axis of the coil material is parallel to the rotation axis of the idler roller 220, thereby preventing the coil material from moving and deflecting during uncoiling, enabling the coil material to be uncoiled continuously and stably, and improving the cutting efficiency of the coil material.

[0059] In some embodiments, it is sufficient that the upper parts of the two limit plates 212 extend upward beyond the adjacent idler roller 220, so as to facilitate the installation and disassembly of the idler roller 220.

[0060] Refer to Figure 2 , in this embodiment, the idler roller 220 can include a roller shaft 221 and rolling elements 222. The two ends of the roller shaft 221 are clamped in the card slot 2121, so that the roller shaft 221 is stably limited on the limit plate 212. The rolling elements 222 are rotatably sleeved on the roller shaft 221, so that the rolling elements 222 can rotate around the axis of the roller shaft 221. When the idler roller 220 bears the coil material, the coil material abuts against the rolling elements 222. When the coil material is uncoiled, the coil material rotates around its own rotation axis and can roll on the arc-shaped support surface, and the rolling elements 222 rotate around the axis of the roller shaft 221, thereby realizing the stable and reliable uncoiling of the coil material and preventing the coil material from deflecting and jamming.

[0061] In some embodiments, in a plane perpendicular to the lateral direction, the cross-sections at both ends of the roller shaft 221 can be in structures such as rectangular, star-shaped, triangular, etc., as long as the roller shaft 221 is stably and reliably limited in the card slot 2121 of the limit plate 212, so as to prevent the roller shaft 221 from rolling and jumping and avoid the idler roller 220 from affecting the uncoiling of the coil material.

[0062] In some other embodiments, in a plane perpendicular to the lateral direction, the cross-section of the end of the roller shaft 221 can also be oval. In some other embodiments, in a plane perpendicular to the lateral direction, the end cross-section of the roller shaft 221 can also be an irregular shape, as long as the roller shaft 221 is stably clamped on the limit plate 212.

[0063] Refer to Figures 1 to 3, in this embodiment, multiple idlers 220 can form a downwardly concave arc-shaped support surface. When a staff member places the coil on the uncoiling mechanism 200 or when the coil is uncoiled, the coil is in a semi-free state. The coil can roll towards the bottom of the arc-shaped support surface under its own gravity. The limit plates 212 can abut against the lateral side walls of the coil to fit and guide the coil with the arc-shaped support surface, so that the rotation axis of the coil is parallel to the rotation axis of the idlers 220, thereby preventing the coil from skewing during rolling uncoiling, solving the problems of material jamming and unsmooth feeding, improving the coil feeding and uncoiling efficiency, and ensuring the processing efficiency of the metal sheet.

[0064] In some embodiments, the arc-shaped support surface can be a symmetric structure. Multiple idlers 220 are symmetrically arranged with respect to the center line extending transversely along the arc-shaped support surface, so as to facilitate the coil to be placed on the arc-shaped support surface, and can effectively prevent the coil from rolling to the outside of the arc-shaped support surface, improving the stability and reliability of the uncoiling mechanism 200.

[0065] In some embodiments, ten idlers 220 can be provided on the support frame 210. The ten idlers 220 can be symmetrically arranged along the center line extending transversely along the arc-shaped support surface to ensure that the coil can be uncoiled stably and continuously.

[0066] In other embodiments, four, six, eight, or twelve idlers 220 can be provided on the support frame 210, so that the coil finally lies 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 jamming.

[0067] In some embodiments, nine idlers 220 can be provided on the support frame 210. The nine idlers 220 can be symmetrically arranged along the center line extending transversely along the arc-shaped support surface, and the rotation axis of one idler 220 is located on the center line of the arc-shaped support surface, and the other eight idlers 220 are symmetrically arranged along the center line extending transversely to ensure that the coil can be uncoiled stably and continuously.

[0068] In other embodiments, three, five, seven, or eleven idlers 220 can be provided on the support frame 210, so that the coil finally lies 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 jamming.

[0069] In other embodiments, the arc-shaped support surface can be an asymmetric structure, so that when the coil is fed onto the arc-shaped support surface or rolled and uncoiled on the arc-shaped support surface, the coil finally rolls to the bottom of the arc-shaped support surface to prevent the coil from rolling to the outside of the uncoiling mechanism 200.

[0070] Refer to Figures 1 to 3, in this embodiment, the distance between any two adjacent rollers 220 is less than the diameter of the reel. When the metal strip on the coil is used up, it prevents the reel from falling into the support frame 210 through the gap between two adjacent rollers 220, thus facilitating the replacement of the coil material and improving the processing efficiency of the metal sheet.

[0071] Refer to Figures 1 to 3 , in this embodiment, in a plane perpendicular to the transverse direction, the arc length of the projection of the arc-shaped trajectory can be greater than 1 / 3 of the outer circumference of the coil. Thus, when the staff feeds the material onto the arc-shaped support surface or the coil unwinds and rolls, it can prevent the coil from rolling outside the arc-shaped support surface, ensuring the stability and reliability during coil unwinding and preventing the potential safety hazard of the coil rolling to the outside and injuring the staff.

[0073] Refer to 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 jaws 330. The two clamping seats 310 may be respectively arranged oppositely on the transverse sides of the bearing platform 100, and both clamping seats 310 can reciprocate longitudinally on the bearing platform 100. The clamping connecting rod 320 may extend transversely. The two ends of the clamping connecting rod 320 may be respectively fixedly connected to the two clamping seats 310. A plurality of clamping jaws 330 may be arranged at intervals transversely on the clamping connecting rod 320, and the clamping jaws 330 can clamp the free end in an openable and closable manner, so that the free end can move away from the unwinding mechanism 200 following the two clamping seats 310.

[0074] When the coil is placed on the unwinding mechanism 200, the free end of the coil moves towards the clamping mechanism 300 and is limited on a plurality of clamping jaws 330. The two clamping seats 310 can move synchronously longitudinally on the bearing platform 100 to drive the clamping connecting rod 320, a plurality of clamping jaws 330 and the free end to move away from the unwinding mechanism 200 simultaneously.

[0075] Refer to Figure 1 , Figures 3 to 5, in this embodiment, the two clamping seats 310 are respectively movably arranged on the transverse sides of the platform frame 110 and are located outside the bearing plate 120. The two clamping seats 310 can move transversely on the platform frame 110 so that the metal strip is located above the bearing plate 120. When the cutting mechanism 500 cuts the metal strip into metal flakes, the metal flakes fall onto the bearing plate 120, facilitating the stacking of multiple metal flakes and enabling the operator to move multiple stacked metal flakes simultaneously, thereby improving the utilization efficiency of the metal flakes.

[0076] In some embodiments, the two clamping seats 310 are respectively slidably arranged on the two clamping movement guide rails 130, which can ensure the stability, reliability and safety of the movement of the clamping seats 310 and improve the cutting accuracy of the metal flakes.

[0077] In some embodiments, multiple jaws 330 are arranged on the clamping connecting rod 320. And in a plane perpendicular to the vertical direction, the projections of the multiple jaws 330 are within the enclosure range of the bearing plate 120, facilitating the multiple jaws 330 to clamp the free end of the metal strip and enabling the metal flakes to fall onto the bearing plate 120.

[0078] In this embodiment, the jaws 330 can be electric jaws 330 or pneumatic jaws 330, enabling the jaws 330 to close to clamp the free end of the metal strip and to open to release the free end of the metal strip, thus facilitating the clamping mechanism 300 to reciprocally clamp the free end of the metal strip and realizing the cyclic cutting of the metal strip.

[0079] In some embodiments, the multiple jaws 330 can be nine jaws 330. The nine jaws 330 are arranged at intervals transversely on the clamping connecting rod 320 to improve the connection strength between the clamping mechanism 300 and the free end of the metal strip.

[0080] In other embodiments, for coils with different axial lengths, the nine jaws 330 can be selectively opened and closed so that some of the jaws 330 relative to the coil open and close while the other part of the jaws 330 stop being used, thereby reducing the usage cost of the clamping mechanism 300.

[0081] In other embodiments, the multiple jaws 330 can be two, three, five, six, seven or eight jaws 330 as long as they can stably and reliably clamp the free end of the metal strip.

[0082] In some embodiments, the multiple jaws 330 are movably arranged transversely on the clamping connecting rod 320 so that the multiple jaws 330 can all move to different positions for coils with different axial lengths, thereby improving the clamping stability and reliability of the clamping mechanism 300.

[0083] In some other embodiments, a tension adjusting member (not shown in the figure) is further provided between the clamping jaws 330 and the clamping connecting rod 320 to facilitate real-time adjustment of the relative positions of the clamping jaws 330 and the clamping connecting rod 320.

[0084] Figure 6 is Figure 5 Partial cross-sectional view taken along C-C in. Figure 7 is Figure 1 Bottom view structural schematic diagram of the structure shown in. Figure 8 is Figure 7 Partial structural schematic diagram taken along D-D in. Figure 9 is one of the structural schematic diagrams of the automatic processing device of the present invention from a longitudinal perspective.

[0085] Refer to 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 disposed at the lower part of the carrying platform 100 to be able to output a driving force. The synchronous rotating shaft 430 is in transmission connection with the clamping driver 410, and both ends of the synchronous rotating shaft 430 are respectively in transmission connection with the two transmission belts 440 to be able to drive the two transmission belts 440 to rotate synchronously. The two transmission belts 440 extend longitudinally, and the two transmission belts 440 are respectively in transmission connection with the two clamping seats 310 to enable the two clamping seats 310 to move synchronously.

[0086] In some embodiments, the clamping driver 410 may be an electric motor. In some other embodiments, the clamping driver 410 may be a servo motor.

[0087] In some embodiments, a differential 420 may be provided between the clamping driver 410 and the synchronous rotating shaft 430 to be able to control the rotation speed of the synchronous rotating shaft 430, thereby controlling the translational speed of the clamping mechanism 300 in the longitudinal direction.

[0088] Refer to Figure 4 , Figures 7 to 9 , in this embodiment, the synchronous rotating shaft 430 is rotatably connected to the lower side of the platform frame 110. The synchronous rotating shaft 430 extends transversely so that the transverse ends of the synchronous rotating shaft 430 are respectively in transmission connection with the two transmission belts 440, thereby driving the two transmission belts 440 to rotate synchronously.

[0089] Refer to 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 are respectively located on the transverse two sides of the platform frame 110. The two transmission belts 440 are respectively connected to the two clamping seats 310 to be able to drive the two clamping seats 310 to reciprocate on the two clamping movement guide rails 130, thereby improving the cutting accuracy and cutting efficiency of the metal sheet.

[0090] The conveyor belt 440 may include two end shafts 441 and a conveyor belt body 442. The two end shafts 441 are arranged at intervals along the longitudinal direction, and both end shafts 441 extend along the transverse direction so that both end shafts 441 can rotate around their own rotation axes. The end shafts 441 at the ends of the two conveyor belts 440 on the same side in the longitudinal direction are drivingly connected to the synchronous shaft 430. The conveyor belt body 442 is rotatably sleeved outside the two end shafts 441 to be able to rotate following the end shafts 441.

[0091] The clamping driver 410 can drive the rotation of one end shaft 441 of the two conveyor belts 440 through the synchronous shaft 430, so that the conveyor belt body 442 rotates around the two end shafts 441, thereby enabling the conveyor belt 440 to drive the clamping mechanism 300 to approach the cutting mechanism 500 and clamp the free end of the metal strip, and also enabling the conveyor belt 440 to drive the clamping mechanism 300 away from the cutting mechanism 500, facilitating the uncoiling of the coil and the cutting mechanism 500 to cut the metal strip, thereby improving the production efficiency of the metal sheet.

[0092] In some embodiments, the conveyor belt body 442 is fixedly connected to the clamping seat 310, so that when the conveyor belt body 442 rotates around the two end shafts 441, it can drive the clamping seat 310 to move longitudinally, facilitating the multiple clamping of the free end of the metal strip.

[0093] In some embodiments, the clamping drive mechanism 400 is arranged close to the cutting mechanism 500, facilitating the routing of the lines inside the automatic processing device and facilitating the maintenance and inspection of the clamping drive mechanism 400 by the staff.

[0094] In some embodiments, the clamping drive mechanism 400 may further include a distance sensor (not shown in the figure). The distance sensor can detect the rotation distance of the conveyor belt body 442 to obtain the moving distance of the clamping seat 310 along the longitudinal direction, thereby facilitating the automatic processing device to process metal sheets of different lengths and improving the production efficiency of the product.

[0095] In some embodiments, the distance sensor may be a laser distance sensor, an ultrasonic distance sensor, an infrared distance sensor, etc.

[0096] In some other embodiments, the distance sensor can also directly obtain the moving distance of the moving seat along the longitudinal direction to enable the processing and production of metal sheets of different lengths.

[0097] Figure 10 It is another schematic structural view of the automatic processing device of the present invention from the longitudinal perspective.

[0098] Refer to Figure 1 、 Figure 4 、 Figure 6 andFigure 10 , in this embodiment, the cutting mechanism 500 may include a base 510, a connecting frame 520, an auxiliary pressing structure 540 and a cutter 560. The base 510 is connected to one end of the carrying platform 100 close to the uncoiling mechanism 200, and the base 510 is used for carrying the metal strip. The connecting frame 520 may be connected to the carrying platform 100. The connecting frame 520 and the upper surface of the base 510 are arranged at intervals in the vertical direction to form a passage interval 530, and the passage interval 530 is used for the metal strip to pass through. The auxiliary pressing structure 540 is connected to the connecting frame 520 in a liftable manner, and the auxiliary pressing structure 540 can move towards the base 510 to press the metal strip against the base 510. The cutter 560 is arranged on the connecting frame 520 so as to be movable in the transverse direction, so as to be able to cut the metal strip into metal flakes.

[0099] After the clamping jaw 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 uncoiling mechanism 200 through the transmission belt 440, so that the coil is uncoiled, and a part of the metal strip of the coil passes through the passage interval 530 to move away from the uncoiling mechanism 200.

[0100] After the clamping seat 310 clamps the free end and moves a preset distance away from the uncoiling mechanism 200, the clamping driver 410 stops running, so that the clamping seat 310 stops on the clamping movement guide rail 130. The auxiliary pressing structure 540 moves towards the base 510 to press and limit a part of the metal coil on the base 510.

[0101] After that, the cutter 560 moves in the transverse direction to cut the metal strip into metal flakes, so as to effectively improve the cutting efficiency and cutting accuracy of the coil and improve the production efficiency of the metal flakes.

[0102] One end of the metal flake close to the cutting mechanism 500 first falls onto the bearing plate 120. After one end of the metal flake falls onto the bearing plate 120, the clamping jaw 330 releases the other end of the metal flake, so that the other end of the metal flake falls flat onto the bearing plate 120, thereby preventing the metal flake from being wrinkled and the like, and facilitating the subsequent use of the metal flake.

[0103] Refer to Figure 1 、 Figure 4 、 Figure 6 And Figure 10 , in this embodiment, the base 510 is fixedly connected to the platform frame 110 and is located at one end of the bearing plate 120 facing the uncoiling mechanism 200 to ensure the stability of the base 510, thereby ensuring the cutting accuracy of the cutter 560.

[0104] Refer to Figure 1 、 Figure 3 And Figure 4, in this embodiment, vertically, the upper surface of the base 510 is higher than the arc-shaped supporting surface of the uncoiling mechanism 200, so as to facilitate the pressing of the metal strip on the base 510. Moreover, when the auxiliary pressing structure 540 presses the metal strip, the auxiliary pressing structure 540 will not drive the coiled material to uncoil, thus ensuring the cutting size accuracy of the metal sheet.

[0105] Refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 9 and Figure 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 respectively located on the transverse two sides of the base 510. 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 transversely, and the two ends of the connecting frame body 522 are respectively 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 interval 530 is formed between the connecting frame body 522 and the base 510. The passage interval 530 is used for the free end of the metal strip to pass through, so as to facilitate the free end of the metal strip to be limited on the clamping jaw 330.

[0106] In some embodiments, both the connecting seat 521 and the connecting frame body 522 are of a frame structure, so as to reduce the weight of the connecting frame 520 while ensuring the structural strength of the connecting seat 521 and the connecting frame body 522, and facilitate the installation, disassembly and maintenance of the cutter 560 and the auxiliary pressing structure 540.

[0107] Refer to Figure 3 , Figure 4 , Figure 6 , Figure 9 and Figure 10 , in this embodiment, the auxiliary pressing structure 540 is disposed on the connecting frame body 522 in a liftable manner, and the auxiliary pressing structure 540 can move towards the base 510 to press and limit the metal strip on the base 510, so as to facilitate the cutter 560 to cut the metal strip.

[0108] The auxiliary pressing structure 540 may include a pressing plate 541, lifting guide columns 542, and a lifting driver 543. The pressing plate 541 extends transversely. The pressing plate 541 is located within the passage interval 530 above the base 510. The upper ends of the lifting guide columns 542 are slidably inserted through the connecting frame body 522, and the lower ends of the lifting guide columns 542 are connected to the pressing plate 541, so that the lifting guide columns 542 can stably and reliably guide the lifting of the pressing plate 541 and improve the lifting accuracy of the pressing plate 541. The lifting driver 543 is disposed on the connecting frame body 522, and the lifting end of the lifting driver 543 is fixedly connected to the pressing plate 541 to drive the pressing plate 541 to lift.

[0109] In some embodiments, the length of the pressing plate 541 in the transverse direction is greater than or equal to the length of the metal strip in the transverse direction, so as to be able to completely press the metal strip onto the base 510 and ensure the cutting accuracy and cutting efficiency of the cutter 560. In other embodiments, the length of the metal strip in the transverse direction is less than or equal to the length of the base 510 in the transverse direction.

[0110] In other embodiments, there may be a plurality of lifting guide columns 542, and the plurality of lifting guide columns 542 are spaced apart on the connecting frame body 522 to further improve the stability and reliability of the auxiliary pressing structure 540.

[0111] In other embodiments, there may be a plurality of lifting drivers 543, and the plurality of lifting drivers 543 are spaced apart on the connecting frame body 522 to improve the lifting efficiency of the pressing plate 541 and ensure the lifting safety and reliability of the pressing plate 541.

[0112] In some embodiments, the lifting driver 543 may be a lifting cylinder. The cylinder body of the lifting cylinder is connected to the connecting frame body 522, and the lifting end of the lifting cylinder is connected to the pressing plate 541 to drive the pressing plate 541 to lift.

[0113] In other embodiments, the lifting driver 543 may also be structures such as a lifting lead screw and a lifting chain, as long as the pressing plate 541 can be lifted relative to the connecting frame body 522.

[0114] 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 in 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.

[0115] In some embodiments, the cutter 560 may be a cutting saw or a laser cutter.

[0116] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 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 passing interval 530. The cutting guide rail 550 extends transversely. The cutter 560 is movably connected to the cutting guide rail 550 so that the cutter 560 can cut the metal strip transversely into metal sheets. The cutting drive structure 570 is drivingly connected to the cutter 560 so that the cutter 560 can move transversely on the cutting guide rail 550.

[0117] After the clamping mechanism 300 clamps the free end away from the uncoiling mechanism 200, the lifting end of 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. The cutting drive structure 570 drives the cutter 560 to move on the cutting guide rail 550 to move from one side to the other side of the metal strip transversely, 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, so as to effectively ensure that the cutting trace of the metal sheet is smooth, the cutting accuracy is high, the cutting efficiency is high, and moreover, it can also reduce the safety hazards caused by manual participation.

[0118] In some embodiments, there may be multiple cutting guide rails 550. The multiple cutting guide rails 550 can be respectively connected to one side wall of the connecting frame body 522 longitudinally away from the uncoiling mechanism 200, or can be respectively connected to one side wall of the two connecting seats 521 longitudinally away from the uncoiling mechanism 200. The multiple cutting guide rails 550 can improve the stability and reliability of the cutter 560 when moving transversely, and ensure the cutting efficiency and cutting accuracy of the cutter 560.

[0119] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 10 In this embodiment, the cutting drive structure 570 is disposed on the connecting frame 520 to be drivingly connected to the cutter 560, so as to drive the cutter 560 to reciprocate transversely. The cutting drive structure 570 may refer to the structure of the above-mentioned transmission belt 440.

[0120] 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 both of 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 following the two cutting rollers 571. The cutting belt body 572 is connected to the cutter 560 so that the cutting belt body 572 reciprocates to drive the cutter 560 to reciprocate. The cutting driver 573 is arranged on the connecting frame 520, and the cutting driver 573 is in transmission connection with the cutting roller 571 to be able to drive the cutting belt body 572 to rotate, thereby being able to drive the cutter 560 to reciprocate.

[0121] In some embodiments, the cutting drive structure 570 does not need to include the cutting rollers 571 and the cutting belt body 572. The cutting drive structure 570 may include a cutting driver 573. The cutting driver 573 is arranged on the cutter 560. A gear is arranged on the driving end of the cutting driver 573. A rack is arranged on the cutting guide rail 550. The gear can be in threaded connection with the rack to drive the cutter 560 to reciprocate on the cutting guide rail 550.

[0122] In some other embodiments, the cutting drive structure 570 does not need to include the cutting rollers 571 and the cutting belt body 572. The cutting drive structure 570 may further include a cutting driver 573 and a transmission lead screw. The cutting driver 573 is in threaded connection with the transmission lead screw. The transmission lead screw is rotatably arranged on the connecting frame 520, and the transmission lead screw penetrates through the cutter 560 and is in threaded connection with the cutter 560 so that when the transmission lead screw rotates around its own rotation axis, it can drive the cutter 560 to reciprocate on the cutting guide rail 550.

[0123] The above embodiments are only illustrative descriptions of the structures. The structures in each embodiment are not fixedly combined structures. Without structural conflicts, the structures in multiple embodiments can be combined and used arbitrarily.

[0124] In some other embodiments, the cutting drive structure 570 may also be applied to the above-mentioned transmission belt 440.

[0125] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 10, in this embodiment, the automatic processing device may further include a guiding mechanism 600. The guiding mechanism 600 may include two guiding plates 610 and a plurality of guiding rollers 620. The two guiding plates 610 are disposed on one end wall of the carrying platform 100 facing the uncoiling mechanism 200, and the two guiding plates 610 are arranged at intervals in the transverse direction. The plurality of guiding rollers 620 are rotatably connected between the two guiding plates 610, and the rotation axes of the plurality of guiding rollers 620 are all parallel to the rotation axis of the supporting roller 220. The plurality of guiding rollers 620 together form an upwardly convex arc-shaped guiding surface, and the uppermost end of the arc-shaped guiding surface is flush with the upper surface of the base 510. The arc-shaped guiding 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 rubbing against the base 510 during the uncoiling process of the coil, thereby protecting the surface quality of the metal strip and preventing the metal strip from being scratched.

[0126] In some other embodiments, the guiding plates 610 extend longitudinally. Between the two guiding plates 610, there may be a first guiding roller 620, a second guiding roller 620, and a third guiding roller 620 that all extend transversely. The first guiding roller 620, the second guiding roller 620, and the third guiding roller 620 are arranged at intervals in the longitudinal direction in sequence. The first guiding roller 620 and the second guiding roller 620 are at the same vertical height. The third guiding roller 620 is disposed close to the uncoiling mechanism 200, and in the vertical direction, the second guiding roller 620 is higher than the third guiding roller 620, and the third guiding roller 620 is higher than the arc-shaped supporting surface, so that after the free end of the metal strip passes through the passage interval 530 and is limited on the clamping jaw 330 after successively adhering to the outer sides of the third guiding roller 620, the second guiding roller 620, and the first guiding roller 620, the tension degree of the metal strip can be increased, so as to ensure the taut state of the metal strip when the auxiliary pressing structure 540 presses the metal strip, facilitate the high-efficiency cutting of the cutter, improve the cutting accuracy of the cutting device 560, and ensure the smoothness of the cutting trace of the metal sheet.

[0127] In some embodiments, the structure of the guiding roller 620 may be set with reference to the structure of the supporting roller 220.

[0128] In some embodiments, the guiding roller 620 may include a roller shaft 221 and rolling elements 222. Both ends of the roller shaft 221 are respectively fixed on the two guiding plates 610. The rolling elements 222 are rotatably sleeved on the roller shaft, so that the rolling elements 222 can rotate around the roller shaft under the action of the frictional force of the metal strip.

[0129] In some embodiments, the uppermost end of the arc-shaped guiding surface, the upper surface of the base 510, and the clamping jaws 330 are located in the same longitudinal plane, so that after being guided by the arc-shaped guiding surface, the metal strip moves longitudinally onto the upper surface of the base 510 and finally onto the clamping jaws 330, thereby ensuring the stability of the metal strip. During the uncoiling of the coil, the movement of the free end, the pressing of the auxiliary pressing structure 540, and the cutting by the cutter 560, the metal strip will not vibrate in the up-and-down direction, ensuring the cutting accuracy of the cutter 560.

[0130] In some embodiments, the guiding mechanism 600 may include a guiding roller 620, so that the metal strip can be bent and attached to a part of the guiding roller 620, and after passing through the guiding roller 620, the metal strip is located in the same longitudinal plane as the upper surface of the base 510 and the clamping jaws 330.

[0131] In this embodiment, the automatic processing device may further include a pressing frame (not shown in the figure). The pressing frame may include two rotating rods and a pressing roller that can rotate around its own rotation axis. One end of each of the two rotating rods is rotatably connected to the opposite sides of the two guiding plates 610, and the other ends of the two rotating rods are rotatably connected to both ends of the pressing roller. The rotation axis of the pressing roller is parallel to the rotation axis of the guiding roller 620. The pressing roller can rotate around the rotation axis of the rotating rod to a position between the guiding mechanism 600 and the uncoiling mechanism 200 to press on the metal strip.

[0132] When the free end of the coil passes through the guidance of the arc-shaped guiding surface, it passes through the passage interval 530 and is limited within the clamping jaws 330. The pressing frame can rotate downward around the rotation axis of the rotating rod under its own gravity, so that the pressing roller presses on the upper surface of the metal strip. Thus, when the clamping mechanism 300 clamps the free end and moves away from the uncoiling mechanism 200, the tension of the metal strip can be increased, making the metal strip in a taut state. Therefore, after the auxiliary pressing structure 540 presses the metal strip, the cutting accuracy and cutting efficiency of the metal strip can be improved, and the quality of the cut metal sheet can be improved.

[0133] In some embodiments, the structure of the pressing roller may refer to the structure of the above-mentioned supporting roller 220. The pressing roller may include a roller shaft 221 and rolling elements 222. The roller shaft 221 is fixedly connected to the rotating rod, and the rolling elements 222 are rotatably sleeved on the roller shaft to be able to press the metal strip and move relative to the metal strip.

[0134] 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.

[0135] In some embodiments, the controller is also capable of controlling the output rotation speed, running time, etc. of the clamping driver 410. In some other embodiments, the controller is also capable of adjusting the preset distance for the movement of the clamping mechanism 300, so as to be able to adjust the size of the metal sheet. In some other embodiments, the controller is also capable of controlling the output rotation speed, running time, etc. of the cutting driver 573, so as to be able to control the moving speed of the cutter 560 in the transverse direction.

[0136] In some embodiments, the controller is also electrically connected to the cutter 560 to control the cutting speed of the cutter 560. In some other embodiments, when the cutter 560 is a cutting saw, the controller can control the rotation speed of the cutting saw, so as to control the cutting speed of the cutting saw.

[0137] Referring to Figures 1 to 10 , the present application provides an automatic processing device for metal sheets. When a staff processes a coil through the automatic processing device, the coil is first placed on the uncoiling mechanism 200. When the coil drops onto the arc-shaped support surface of the uncoiling mechanism 200, the coil rolls on the arc-shaped support surface under its own gravity and the guidance of the limiting plate 212, and finally stops at the bottom of the arc-shaped support surface. This feeding process is fast, efficient, and can effectively prevent problems such as material jamming, material movement, and material breakage during the uncoiling process of the coil.

[0138] After the coil stops at the arc-shaped support surface, the free end of the coil is moved to the arc-shaped guiding surface, and then the free end passes through the passing interval 530 and is limited within a plurality of jaws 330. Then, the clamping driver 410 drives the transmission belt 440 to rotate through the synchronous rotating shaft 430, so as to drive the clamping seat 310 to move longitudinally away from the base 510, and the free end follows the clamping seat 310 to move away from the base 510, and the coil uncoils and rolls on the uncoiling mechanism 200.

[0139] After the clamping mechanism 300 moves away from the base 510, the clamping driver 410 stops running, and the clamping mechanism 300 and the free end stop on the clamping guide rail. Then, the lifting driver 543 drives the pressing plate 541 to move towards the base 510 to press and limit the metal strip on the base 510, so that a part of the metal strip is limited between the clamping mechanism 300 and the cutting mechanism 500.

[0140] After a part of the metal strip is limited between the clamping mechanism 300 and the cutting mechanism 500, the cutting driver 573 drives the cutter 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, the end of the metal sheet close to the base 510 first drops onto the bearing plate 120, and then the jaws 330 release the other end of the metal sheet, so that the other end of the metal sheet drops onto the bearing plate 120, thereby facilitating the flat placement of the metal sheet.

[0141] After that, the clamping driver 410 is turned on. The clamping driver 410 moves the clamping seat 310 towards the base through the transmission belt 440, so that the clamping jaws 330 can continue 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 cuts of the coil, improving the production efficiency of the metal sheet, ensuring the processing accuracy of the metal sheet, and reducing the safety hazards caused by manual participation.

[0142] The present application also provides an automatic processing method for metal sheets, which is applied to any one of the above automatic processing devices, thereby enabling realization. The automatic processing method includes:

[0143] Step S110: Place the coil on the arc-shaped support surface of the uncoiling mechanism 200 with its axis along the transverse direction, and the coil rolls to the bottom of the arc-shaped support surface.

[0144] Step S120: Pass the free end of the coil through the cutting mechanism 500.

[0145] Step S130: The clamping mechanism 300 clamps the free end of the coil.

[0146] Step S210: The clamping mechanism 300 moves in the longitudinal direction away from the uncoiling mechanism 200, driving the free end away from the uncoiling mechanism 200, and the coil rolls on the arc-shaped support surface.

[0147] Step S220: After the clamping mechanism 300 moves to a preset distance and stops, the cutting mechanism 500 cuts the metal strip.

[0148] When the coil needs to be processed and used, place the coil on the arc-shaped support surface of the uncoiling mechanism 200 with its axis extending along the transverse direction. The coil rolls on the arc-shaped support surface and finally rolls to the bottom of the arc-shaped support surface.

[0149] 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 in the longitudinal direction away from the uncoiling mechanism 200, and the free end moves along the longitudinal direction following the clamping mechanism 300, and the coil rolls and unwinds on the arc-shaped support surface. When the coil rolls and unwinds on the arc-shaped support surface, the uncoiling mechanism 200 can effectively prevent the coil from skewing and jamming, and can prevent the coil from moving and breaking, improve the efficiency of coil processing, and prevent the occurrence of safety hazards.

[0150] 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. After that, the clamping mechanism 300 releases the metal sheet, so that the metal sheet falls onto the loading platform 100.

[0151] The clamping mechanism 300 moves longitudinally towards the cutting mechanism 500 to continue clamping the free end of the coil, so as to enable reciprocating cutting of the coil and improve the processing efficiency of the coil.

[0152] In this embodiment, the automatic processing method may further include:

[0153] Step S230, after the cutting mechanism 500 cuts off the metal strip, the clamping mechanism 300 releases the metal sheet, and the clamping mechanism 300 can move longitudinally towards the uncoiling mechanism 200 to continue clamping the free end of the coil.

[0154] After the clamping mechanism 300 releases the metal sheet, it moves towards the uncoiling mechanism 200 to continue clamping the free end of the coil, so as to enable reciprocating cutting of the coil and improve the processing efficiency of the coil.

[0155] 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 further include:

[0156] Step S221, after the clamping mechanism 300 moves longitudinally away from the uncoiling mechanism 200 by a preset distance, the auxiliary pressing structure 540 moves towards the base 510 to press the metal strip onto the base 510; the cutter 560 moves transversely to cut the metal strip into metal sheets.

[0157] The auxiliary pressing structure 540 presses the metal strip onto the base 510, and the cutter 560 moves transversely to cut the metal strip into metal sheets. A part of the metal strip is limited within the clamping mechanism 300 and the cutting mechanism 500, so as to ensure the reliability of the cutter 560 during the process of cutting the metal strip, improve the smoothness of the cutting trace, and ensure the cutting accuracy and efficiency of the metal sheet.
