Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to an automatic packaging machine for rewinding silicon steel. Background Technology

[0002] Silicon steel sheets produced by silicon steel sheet manufacturers need to be stored and transported after being wound into coils. During storage and transportation, they need to be packaged to prevent moisture and oxidation.

[0003] Existing technologies also offer some solutions. For example, a patent application with publication number CN207311941U describes a silicon steel coil packaging support, which includes two parallel longitudinal tracks connected and fixed by a crossbar. A packaging paper support frame is fixedly installed at the front end of each longitudinal track. The packaging paper support frame includes an upper crossbeam, a lower crossbeam, and uprights. The lower crossbeam is welded to the longitudinal tracks, and an upward-facing upright is welded to each end of the lower crossbeam. The upper crossbeam is welded between the two uprights. This design is simple in structure, convenient to use, time-saving, labor-saving, and safe and reliable. The longitudinal tracks are wrapped with a rubber outer layer to prevent damage to the silicon steel coil. It improves efficiency and safety during the packaging process and reduces operational difficulty.

[0004] While the above application improves efficiency in the packaging process, other problems still exist in actual use. For example, in order to prevent the silicon steel coil from coming into contact with the ground during subsequent transportation, which may cause the surface of the silicon steel coil to be scratched, it is necessary to wrap the silicon steel coil with tape of a certain thickness so that it is placed on the ground with a certain distance. However, this packaging operation is relatively troublesome and requires manual assistance.

[0005] Therefore, the present invention provides an automatic packaging machine for rewinding silicon steel. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic silicon steel rewinding and packaging machine, including a work frame, which is composed of two vertical frames and a transmission plate is arranged between the two vertical frames. In use, the silicon steel coil is placed on the transmission plate. A positioning frame is installed on the upper end face of the transmission plate. The positioning frame is used to fix and position the silicon steel coil to be packaged. A packaging ring is rotatably provided on the side wall of the work frame. The surface of the packaging ring is covered with protective tape. The packaging ring can rotate on the side wall of the work frame to wrap the silicon steel coil with protective tape.

[0007] In one embodiment of the present invention, multiple positioning frames are arranged in an array above the transmission plate. A positioning plate is slidably mounted on the upper surface of each positioning frame. The shape of the positioning plate matches the arc shape of the silicon steel coil. A U-shaped fixing frame is provided on the surface of the positioning plate, and a threaded fastening rod is provided on the surface of the U-shaped fixing frame. The U-shaped fixing frame is used to fix and limit the positioning plate. A rubber pad is provided at the contact position between the positioning plate and the silicon steel coil. During operation, when the silicon steel coil is located between two adjacent positioning plates, the adjacent positioning plates can be controlled... The two positioning plates are brought close together, so that the two adjacent positioning plates abut against the outer circumference of the silicon steel coil. Under the action of the two adjacent positioning plates, the silicon steel coil can be fixed, which facilitates the subsequent packaging and protective tape. Moreover, under the action of the U-shaped fixing frame and the threaded fastening rod, the position of the threaded fastening rod can be adjusted so that the end of the threaded fastening rod abuts against the side wall of the positioning plate, thereby maintaining the vertical position of the positioning plate and supporting the silicon steel coil. This prevents the positioning plate from tilting due to supporting different silicon steel coils for a long time.

[0008] In one embodiment of the present invention, a contact point one is installed on the side wall of the positioning frame, and a contact point two is installed on the side wall of the work frame. When the positioning frame moves the silicon steel coil, it will move the contact point one closer to the contact point two and make contact with the contact point two.

[0009] In one embodiment of the present invention, a connecting frame is installed on the side wall of the work frame, and an mounting platform is installed at the end of the connecting frame away from the work frame. Multiple sets of drive wheels are rotatably arranged on the inner wall of the mounting platform. The drive wheels are designed in a two-by-two circular array. The packing ring is disposed between two sets of drive wheels, and the outer surface of the drive wheels is in contact with the outer surface of the packing ring. During operation, when the controller receives the contact signal of contact point two and the positioning frame stops moving, the controller controls all drive wheels to rotate. Since the outer surface of all drive wheels is in contact with the surface of the packing ring, when all drive wheels rotate, the drive wheels will drive the packing ring to rotate, and the packing ring will drive the protective tape to rotate. Thus, the protective tape will gradually wrap around the surface of the silicon steel coil, realizing automatic packing of the silicon steel coil.

[0010] In one embodiment of the present invention, the drive wheel is made of rubber, and the inner wall of the mounting platform is provided with a rotating shaft adapted to the drive wheel. The packing ring is an incomplete ring, that is, the surface of the packing ring is provided with a gap, the height of which is greater than the height of the silicon steel coil. During operation, since the drive wheel is made of rubber, the drive wheel can easily rotate the packing ring when all the drive wheels rotate, which is beneficial for packing the silicon steel coil. Moreover, since the packing ring is an incomplete ring, the silicon steel coil can be easily moved to the inside of the packing ring, which makes it easy for the packing ring to rotate along the inner wall of the silicon steel coil and wrap the protective tape around the surface of the silicon steel coil.

[0011] In one embodiment of the present invention, an L-shaped support plate is installed on the side wall of the work frame, and a clamping unit is installed at the end of the L-shaped support plate away from the work frame. The clamping unit is used to clamp the protective tape.

[0012] In one embodiment of the present invention, the clamping unit includes an electric push rod, which is mounted on the side wall of the L-shaped support plate. The telescopic end of the electric push rod is provided with a fixed inclined plate. The side wall of the fixed inclined plate is slidably provided with an attachment roller and an attachment roller. The attachment roller and the attachment roller are used to clamp the protective tape. The attachment roller and the attachment roller are designed to be relatively inclined, with the attachment roller being located above the attachment roller.

[0013] In one embodiment of the present invention, an electric telescopic column is installed at the telescopic end of the electric push rod one, and the fixed inclined plate is installed at the telescopic end of the electric telescopic column. The side wall of the L-shaped support plate is provided with a groove that matches the electric push rod one. During operation, when the protective tape adheres to the surface of the silicon steel coil, the telescopic end of the electric telescopic column is controlled to drive the fixed inclined plate to move, so that the fixed inclined plate drives the first and second attaching rollers away from the protective tape, thereby preventing the first and second attaching rollers from affecting the rotation of the packing ring during the subsequent rotation process.

[0014] In one embodiment of the present invention, two electric push rods are installed on the side wall of the fixed inclined plate. The telescopic ends of the two electric push rods are respectively connected to the side walls of the first and second attaching rollers. The first and second attaching rollers are made of non-stick material. During operation, if the first and second attaching rollers fail to stably clamp the protective tape during normal use, the telescopic ends of the electric push rods can be controlled to move, so that the telescopic ends drive the first and second attaching rollers to move, that is, the first and second attaching rollers will move closer to each other and abut against each other, which facilitates the clamping of the protective tape.

[0015] In one embodiment of the present invention, an electric push rod three is installed on the inner wall of the packing ring, and a cutter is installed on the telescopic end of the electric push rod three. During operation, after the silicon steel coil is packed once, the electric push rod one can be controlled to drive the fixed inclined plate and the first and second attaching rollers to return to their initial positions. Then, the positions of the first and second attaching rollers are adjusted, and one side of the protective tape is clamped. After that, the telescopic end of the electric push rod three is controlled to move, so that the telescopic end drives the cutter to move down and cut the protective tape. This makes it convenient for the second attaching rollers to pull the remaining protective tape to the surface of the subsequent silicon steel coil, so as to achieve continuous packing of silicon steel coils.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The present invention discloses an automatic packaging machine for rewinding silicon steel. By controlling an electric push rod, a fixed inclined plate and two attaching rollers (one and two) are moved closer to the silicon steel coil. Since the first attaching roller is located above the second attaching roller, it will first contact the upper surface of the silicon steel coil, while the second attaching roller will press against the outer circumference of the silicon steel coil. Protective tape will adhere to the surface of the silicon steel coil. Since the first and second attaching rollers are slidably mounted on the side wall of the fixed inclined plate, once the protective tape adheres to the surface of the silicon steel coil, the first and second attaching rollers can be moved away from the silicon steel coil. This facilitates the rotation of the subsequent packaging ring.

[0018] The automatic packaging machine for rewinding silicon steel described in this invention, when the controller receives the contact signal from contact point two and the positioning frame stops moving, controls all drive wheels to rotate. Since the outer surface of all drive wheels is in contact with the surface of the packaging ring, when all drive wheels rotate, the drive wheels will drive the packaging ring to rotate, and the packaging ring will drive the protective tape to rotate. Thus, the protective tape will gradually wrap around the surface of the silicon steel coil, realizing the automatic packaging of the silicon steel coil. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Reference Figures 1 to 11 As shown in the embodiment of the present invention, an automatic silicon steel rewinding and packaging machine includes a work frame 1, which is composed of two vertical frames and a transmission plate 2 is arranged between the two vertical frames. In use, the silicon steel coil 201 is placed on the transmission plate 2. A positioning frame 3 is installed on the upper end face of the transmission plate 2. The positioning frame 3 is used to fix and position the silicon steel coil 201 to be packaged. A packaging ring 4 is rotatably arranged on the side wall of the work frame 1. A protective tape 401 is installed on the surface of the packaging ring 4. The packaging ring 4 can rotate on the side wall of the work frame 1, thereby wrapping the silicon steel coil 201 with the protective tape 401.

[0034] During operation, the silicon steel coil 201 to be packaged is placed above the conveyor plate 2, and the silicon steel coil 201 is fixed by two adjacent positioning frames 3 above the conveyor plate 2. Then, the positioning frames 3 and the silicon steel coil 201 are moved closer to the packaging ring 4 by the conveyor plate 2. When the silicon steel coil 201 moves to the side of the packaging ring 4, the movement of the conveyor plate 2 stops. Then, the rotation of the packaging ring 4 drives the protective tape 401 to rotate, so that the protective tape 401 will rotate along the surface of the silicon steel coil 201 and wrap around the surface of the silicon steel coil 201, realizing the automatic packaging of the silicon steel coil 201. After the packaging ring 4 rotates a certain number of times, the surface of the silicon steel coil can be packaged with tape of a certain thickness, which facilitates its subsequent transfer.

[0035] See attached document Figure 11 As shown, this is a top view of silicon steel coil 201 after it has been packaged.

[0036] Multiple positioning frames 3 are arranged in an array above the transmission plate 2. A positioning plate 301 is slidably mounted on the upper surface of the positioning frame 3. The shape of the positioning plate 301 is adapted to the arc shape of the silicon steel coil 201. A U-shaped fixing frame 5 is provided on the surface of the positioning plate 301. A threaded fastening rod 501 is provided on the surface of the U-shaped fixing frame 5. The U-shaped fixing frame 5 is used to fix and limit the positioning plate 301. A rubber pad is provided at the contact position between the positioning plate 301 and the silicon steel coil 201. A rubber pad is also provided on the transmission plate 2.

[0037] During operation, when the silicon steel coil 201 is located between two adjacent positioning plates 301, the two adjacent positioning plates 301 can be controlled to move closer to each other, so that the two adjacent positioning plates 301 abut against the outer circumference of the silicon steel coil 201. That is, under the action of the two adjacent positioning plates 301, the silicon steel coil 201 can be fixed, which facilitates the subsequent packaging with protective tape 401. Moreover, under the action of the U-shaped fixing frame 5 and the threaded fastening rod 501, the position of the threaded fastening rod 501 can be adjusted so that the end of the threaded fastening rod 501 abuts against the side wall of the positioning plate 301, thereby maintaining the vertical position of the positioning plate 301 and supporting the silicon steel coil 201, preventing the positioning plate 301 from tilting due to supporting different silicon steel coils 201 for a long time.

[0038] The side wall of the positioning frame 3 is equipped with a contact point 6, and the side wall of the working frame 1 is equipped with a contact point 101. When the positioning frame 3 moves the silicon steel coil 201, it will move the contact point 6 closer to the contact point 101 and make contact with the contact point 101.

[0039] During operation, when the transmission plate 2 moves the positioning frame 3 and the silicon steel coil 201 on its upper surface toward the side closer to the packing ring 4, the positioning frame 3 will simultaneously move the first contact 6. Then, the first contact 6 will contact the second contact 101, and the second contact 101 will transmit the contact signal to the external controller. The controller will first control the transmission plate 2 to stop the movement of the positioning frame 3, and then control the packing ring 4 to rotate, so that the packing ring 4 drives the protective tape 401 to rotate, and the protective tape 401 will wrap around the surface of the silicon steel coil 201, realizing the automatic packing function of the silicon steel coil 201.

[0040] A connecting frame 7 is installed on the side wall of the work frame 1. An installation platform 8 is installed at the end of the connecting frame 7 away from the work frame 1. Multiple sets of drive wheels 9 are rotatably arranged on the inner wall of the installation platform 8. The drive wheels 9 are designed in a two-by-two circular array. The packing ring 4 is arranged between the two sets of drive wheels 9. The outer surface of the drive wheel 9 is in contact with the outer surface of the packing ring 4.

[0041] During operation, when the controller receives the contact signal from contact point 101 and the positioning frame 3 stops moving, the controller controls all drive wheels 9 to rotate. Since the outer surface of all drive wheels 9 is in contact with the surface of the packing ring 4, when all drive wheels 9 rotate, the drive wheels 9 will drive the packing ring 4 to rotate, and the packing ring 4 will drive the protective tape 401 to rotate. Thus, the protective tape 401 will gradually wrap around the surface of the silicon steel coil 201, realizing automatic packing of the silicon steel coil.

[0042] The drive wheel 9 is made of rubber, and the inner wall of the mounting platform 8 is provided with a rotating shaft that is compatible with the drive wheel 9. The packing ring 4 is an incomplete ring, that is, the surface of the packing ring 4 is provided with a gap, and the height of the gap is greater than the height of the silicon steel coil 201.

[0043] During operation, since the drive wheel 9 is made of rubber, the drive wheel 9 can easily rotate the packing ring 4 when all the drive wheels 9 rotate, which is beneficial for packing the silicon steel coil 201. Since the packing ring 4 is an incomplete ring, the silicon steel coil 201 can easily move to the inside of the packing ring 4, which makes it easy for the packing ring 4 to rotate along the inner wall of the silicon steel coil 201 and wrap the protective tape 401 around the surface of the silicon steel coil 201.

[0044] The side wall of the work frame 1 is equipped with an L-shaped support plate 10, and the end of the L-shaped support plate 10 away from the work frame 1 is equipped with a clamping unit, which is used to clamp the protective tape 401.

[0045] The clamping unit includes an electric push rod 11, which is mounted on the side wall of the L-shaped support plate 10. The telescopic end of the electric push rod 11 is provided with a fixed inclined plate 12. The side wall of the fixed inclined plate 12 is slidably provided with an attachment roller 13 and an attachment roller 24. The attachment roller 13 and the attachment roller 24 are used to clamp the protective tape 401. The attachment roller 13 and the attachment roller 24 are designed to be relatively inclined, with the attachment roller 13 located above the attachment roller 24.

[0046] During operation, in the initial state, the positions of the first attachment roller 13 and the second attachment roller 14 are as shown in the attached figure. Figure 8As shown, since the first attaching roller 13 and the second attaching roller 14 are designed to be relatively inclined, that is, they are not on the same vertical line, the first attaching roller 13 and the second attaching roller 14 can clamp the protective tape 401. When the silicon steel coil 201 moves between the two packing rings 4, the control electric push rod 11 drives the fixed inclined plate 12 and the first attaching roller 13 and the second attaching roller 14 to move towards the side closer to the silicon steel coil 201. Since the first attaching roller 13 is located above the second attaching roller 14, the subsequent... The first attaching roller 13 will first contact the upper end face of the silicon steel coil 201, while the second attaching roller 14 will press against the outer circumference of the silicon steel coil 201, and the protective tape 401 will adhere to the surface of the silicon steel coil 201. Since the first attaching roller 13 and the second attaching roller 14 are slidably set on the side wall of the fixed inclined plate 12, when the protective tape 401 adheres to the surface of the silicon steel coil 201, the first attaching roller 13 and the second attaching roller 14 can be controlled to move away from the silicon steel coil 201, which facilitates the subsequent rotation of the packaging ring 4.

[0047] The telescopic end of the electric push rod 11 is equipped with an electric telescopic column 15, and the fixed inclined plate 12 is installed on the telescopic end of the electric telescopic column 15. The side wall of the L-shaped support plate 10 is provided with a groove that matches the electric push rod 11. During operation, when the protective tape 401 adheres to the surface of the silicon steel coil 201, the telescopic end of the electric telescopic column 15 is controlled to drive the fixed inclined plate 12 to move, so that the fixed inclined plate 12 drives the first attaching roller 13 and the second attaching roller 14 away from the protective tape 401, thereby preventing the attaching roller 13 and the second attaching roller 14 from affecting the rotation of the packing ring 4 during the subsequent rotation process.

[0048] Two electric push rods 16 are installed on the side wall of the fixed inclined plate 12. The telescopic ends of the two electric push rods 16 are respectively connected to the side walls of the first and second attachment rollers 13 and 14. The first and second attachment rollers 13 and 14 are made of non-stick material. During operation, if the first and second attachment rollers 13 and 14 fail to stably clamp the protective tape 401 during normal use, the telescopic ends of the electric push rods 16 can be controlled to move, so that the telescopic ends drive the first and second attachment rollers 13 and 14 to move, that is, the first and second attachment rollers 13 and 14 will approach each other and abut against each other, which facilitates the clamping of the protective tape 401.

[0049] Moreover, when the protective tape 401 adheres to the surface of the silicon steel coil 201, the first application roller 13 and the second application roller 14 can be controlled to move away from each other so that they no longer clamp the protective tape 401. Then, the fixed inclined plate 12 can be controlled to move the first application roller 13 and the second application roller 14 away from the protective tape 401. This can avoid the problem that the first application roller 13 and the second application roller 14 will take away the protective tape 401 adhering to the surface of the silicon steel coil 201 when they move.

[0050] Furthermore, the first and second rollers 13 and 14 are made of non-stick material, which facilitates their separation from the protective tape 401. Specifically, the non-stick material can be an anti-stick coating, such as Teflon, on the surface of the first and second rollers 13 and 14.

[0051] The inner wall of the packing ring 4 is equipped with an electric push rod 17, and the telescopic end of the electric push rod 17 is equipped with a cutter 18. During operation, after the silicon steel coil 201 is packed once, the electric push rod 11 can be controlled to drive the fixed inclined plate 12 and the attaching rollers 13 and 24 to return to their initial positions. The positions of the attaching rollers 13 and 24 are adjusted, and one side of the protective tape 401 is clamped. Then, the telescopic end of the electric push rod 17 is controlled to move, so that the telescopic end drives the cutter 18 to move down and cut the protective tape 401. This makes it convenient for the attaching rollers 13 and 2 to pull the remaining protective tape 401 to the surface of the subsequent silicon steel coil 201, so as to achieve continuous packing of the silicon steel coil 201.

[0052] Working principle: The silicon steel coil 201 to be packaged is placed on the conveyor plate 2 and fixed by two adjacent positioning frames 3 on the conveyor plate 2. Then, the positioning frames 3 and the silicon steel coil 201 are controlled by the conveyor plate 2 to move towards the side of the packaging ring 4. When the silicon steel coil 201 moves to the side of the packaging ring 4, the movement of the conveyor plate 2 stops. Then, under the rotation of the packaging ring 4, the protective tape 401 can be driven to rotate, so the protective tape 401 will rotate along the surface of the silicon steel coil 201 and wrap around the surface of the silicon steel coil 201, realizing the automatic packaging of the silicon steel coil 201.

[0053] When the silicon steel coil 201 is located between two adjacent positioning plates 301, the two adjacent positioning plates 301 can be controlled to move closer to each other, so that the two adjacent positioning plates 301 abut against the outer circumference of the silicon steel coil 201. That is, under the action of the two adjacent positioning plates 301, the silicon steel coil 201 can be fixed, which facilitates the subsequent packaging with protective tape 401. Moreover, under the action of the U-shaped fixing frame 5 and the threaded fastening rod 501, the position of the threaded fastening rod 501 can be adjusted so that the end of the threaded fastening rod 501 abuts against the side wall of the positioning plate 301, thereby maintaining the vertical position of the positioning plate 301 and supporting the silicon steel coil 201, preventing the positioning plate 301 from tilting due to supporting different silicon steel coils 201 for a long time.

[0054] When the transmission plate 2 moves the positioning frame 3 and the silicon steel coil 201 on its upper surface closer to the packing ring 4, the positioning frame 3 simultaneously moves the first contact 6. Then, the first contact 6 contacts the second contact 101, and the second contact 101 transmits a contact signal to the external controller. The controller first controls the transmission plate 2 to stop the movement of the positioning frame 3, and then controls the packing ring 4 to rotate. This causes the packing ring 4 to rotate the protective tape 401, and the protective tape 401 wraps around the surface of the silicon steel coil 201, achieving the desired effect on the silicon steel coil. The automatic packaging function of steel coil 201: When the controller receives the contact signal of contact point 2 101 and the positioning frame 3 stops moving, the controller controls all drive wheels 9 to rotate. Since the outer surface of all drive wheels 9 is in contact with the surface of the packaging ring 4, when all drive wheels 9 rotate, the drive wheels 9 will drive the packaging ring 4 to rotate, and the packaging ring 4 will drive the protective tape 401 to rotate. Thus, the protective tape 401 will gradually wrap around the surface of the silicon steel coil 201, realizing the automatic packaging of the silicon steel coil.

[0055] In the initial state, the positions of the first bonding roller 13 and the second bonding roller 14 are as shown in the attached figure. Figure 8 As shown, since the first attaching roller 13 and the second attaching roller 14 are designed to be relatively inclined, that is, they are not on the same vertical line, the first attaching roller 13 and the second attaching roller 14 can clamp the protective tape 401. When the silicon steel coil 201 moves between the two packing rings 4, the control electric push rod 11 drives the fixed inclined plate 12 and the first attaching roller 13 and the second attaching roller 14 to move towards the side closer to the silicon steel coil 201. Since the first attaching roller 13 is located above the second attaching roller 14, the subsequent... The first attaching roller 13 will first contact the upper end face of the silicon steel coil 201, while the second attaching roller 14 will press on the outer circumferential surface of the silicon steel coil 201, and the protective tape 401 will adhere to the surface of the silicon steel coil 201. Since the first attaching roller 13 and the second attaching roller 14 are slidably set on the side wall of the fixed inclined plate 12, when the protective tape 401 adheres to the surface of the silicon steel coil 201, the first attaching roller 13 and the second attaching roller 14 can be controlled to move away from the silicon steel coil 201, which facilitates the rotation of the subsequent packaging ring 4.

[0056] When the protective tape 401 adheres to the surface of the silicon steel coil 201, the telescopic end of the electric telescopic column 15 is controlled to move the fixed inclined plate 12, so that the fixed inclined plate 12 moves the first attachment roller 13 and the second attachment roller 14 away from the protective tape 401. This avoids the attachment rollers 13 and 14 affecting the rotation of the packing ring 4 during subsequent rotation. If the attachment rollers 13 and 14 fail to stably clamp the protective tape 401 during normal use, the telescopic end of the electric push rod 2 16 can be controlled to move, so that its telescopic end moves the attachment rollers 13 and 14. That is, the attachment rollers 13 and 14 will approach each other and abut against each other, which facilitates the clamping of the protective tape 401.

[0057] Furthermore, when the protective tape 401 adheres to the surface of the silicon steel coil 201, the first and second application rollers 13 and 14 can be controlled to move away from each other, so that they no longer clamp the protective tape 401. Then, the fixed inclined plate 12 can be controlled to move the first and second application rollers 13 and 14 away from the protective tape 401. This avoids the problem of the first and second application rollers 13 and 14 carrying away the protective tape 401 adhering to the surface of the silicon steel coil 201 when they move. After the silicon steel coil 201 is packaged in one go, the electric push rod 11 can be controlled to move the first application roller 11 to move the second application roller 14 away from the surface of the silicon steel coil 201. The fixed inclined plate 12 and the first and second attaching rollers 13 and 2 14 are returned to their initial positions. The positions of the first and second attaching rollers 13 and 2 14 are adjusted, and one side of the protective tape 401 is clamped. Then, the telescopic end of the electric push rod 3 17 is controlled to move, so that the telescopic end drives the cutter 18 to move down and cut the protective tape 401. This makes it convenient for the second attaching rollers 13 and 2 14 to pull the remaining protective tape 401 to the surface of the subsequent silicon steel coil 201, so as to achieve continuous packaging of the silicon steel coil 201.
