Description

Technical Field

[0001] The invention relates to the technical field of steel coil processing, in particular to longitudinal shearing and slitting equipment. Background Art

[0002] The patent document with the Chinese patent authorization announcement number CN215151825U discloses a technical solution named "A striping device for coil processing", which includes the following technical features: including an unwinder, a leveler, a lifting and guiding mechanism, a laminating machine, a striping machine, a side material winding machine, a tension machine, and a winding machine arranged from right to left. In this technical solution, the steel coil is directly transported to the leveler by the unwinder. Since the diameter of the steel coil will gradually decrease during the unwinding process, the output speed of the steel coil is prone to change, which not only easily leads to low accuracy in the transfer of the steel coil, but also easily causes the steel coil to be scratched or scratched due to the leveling process of the leveler, which greatly affects the quality of the steel coil processing. In addition, in this technical solution, the striping is directly performed after the steel coil is coated, so the accuracy of the striping is limited, which will affect the striping quality of the steel coil. At the same time, in this technical solution, the steel coil is directly transported to the winding machine using a tension machine. Although the unwound steel coil is flattened, it will still be deformed during the subsequent transportation and processing. Direct rewinding will not only easily affect the stability of the steel coil, but also easily lead to poor quality of the steel coil.

The longitudinal moving frame 121 can make longitudinal reciprocating motion between the material support gap 111 and the uncoiler 13, the lifting drive mechanism 122 is arranged on the longitudinal moving frame 121, and the material support frame 123 is arranged on the lifting end of the lifting drive mechanism 122, so that the material support frame 123 can be lifted and lowered in and out of the material support gap 111 and can longitudinally enter and exit the material support gap 111. Such a material preparation platform 11 and transfer vehicle 12 are very simple and reliable, which can not only accurately position the steel coil, but also accurately transfer the steel coil, thereby helping to further improve the speed and accuracy of the steel coil up and down, and thus improve production safety and efficiency.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, a longitudinal guide rail 124 is provided between the material preparation table 11 and the uncoiler 13, and a travel roller 125 is provided on the longitudinal moving frame 121, and the travel roller 125 is driven by a first motor 126 provided on the longitudinal moving frame 121; the lifting drive mechanism 122 uses a hydraulic cylinder to realize lifting drive. This not only facilitates manufacturing, but also ensures that the longitudinal transfer of the steel coil is very accurate and stable, thereby helping to further improve the reliability and applicability of the longitudinal shearing and slitting equipment.

[0040] like Figure 1 and Figure 2 As shown, the unwinding shaft 131 is rotatably connected at the rear end and suspended at the front end, and a swinging support shaft mechanism 14 is provided on the side of the uncoiler 13. The swinging support shaft mechanism 14 is driven by a hydraulic cylinder to swing a bracket to lift the front end of the unwinding shaft 131. A roller is provided on the swing end of the swing bracket to roll with the unwinding shaft 131. This not only facilitates the unwinding shaft 131 to support the unwinding extremely stably, but also facilitates the up and down movement of the steel coil, thereby better meeting the needs of actual use.

The longitudinal roller body 1232 can remain unchanged after long-term use, so it does not need to be replaced frequently, which can help reduce the cost of use and maintenance.

[0043] like Figure 4 As shown, the steel cylinder 1234 is coated with a polyurethane coating layer 1237, which can avoid scratches or wear on the steel coil.

[0044] like Figure 5As shown, the front clamping shearing machine 2 and the rear clamping shearing machine 9 include a pair of roller clamping mechanisms 21 and a lifting and shearing mechanism 22 which are arranged in sequence side by side along the conveying direction of the steel coil. The lifting and shearing mechanism 22 includes a fixed frame 221, a lifting frame 222, an upper blade 223, a lower blade 224, and an elastic pressing mechanism 225. A supporting platform 226 is provided on the fixed frame 221. The lifting frame 222 can be vertically movably arranged on the fixed frame 221.

The roller clamping mechanism 21 can stably improve the accuracy and stability of the steel coil transfer. The elastic material pressing mechanism 225 can be used to elastically press the steel coil when the lifting and shearing mechanism 22 shears the steel coil, thereby facilitating a smoother and more accurate shearing process, thereby further helping to improve the shearing quality.

[0045] like Figure 5 and Figure 6 As shown, the elastic pressing mechanism 225 includes a positioning block 2251, a vertical shaft 2252, a spring 2253, a pressing block 2254, and at least one anti-falling nut 2255. The positioning block 2251 is arranged on the side wall of the lifting frame 222. The upper end of the vertical shaft 2252 can vertically slide through the positioning block 2251. The anti-falling nut 2255 is threadedly mounted on the upper end of the vertical shaft 2252 that passes through the positioning block 2251. The anti-falling nut 2255 can prevent The vertical shaft 2252 is prevented from disengaging downward from the positioning block 2251, and the spring 2253 is sleeved on the vertical shaft 2252 below the positioning block 2251. The pressing block 2254 is arranged on the lower end of the vertical shaft 2252, and the upper and lower ends of the spring 2253 are elastically pressed against the bottom surface of the positioning block 2251 and the top surface of the pressing block 2254 respectively; a rubber pad 2256 is arranged on the bottom surface of the pressing block 2254, and the rubber pad 2256 is located directly above the supporting platform 226.

[0046] like Figures 7 to 9As shown, the upper and lower film laminating device 3 includes a frame 31, a pair of roller film pressing mechanisms 32, an upper film placing mechanism 33, and a lower film placing mechanism 34. The pair of roller film pressing mechanisms 32 are arranged in the middle of the frame 31, and the upper film placing mechanism 33 and the lower film placing mechanism 34 are respectively arranged on the upper and lower ends of the frame 31; the upper film placing mechanism 33 and the lower film placing mechanism 34 include a winding roller 331 and a swing positioning mechanism 332.

Such an upper and lower laminating device 3 can stably achieve the effect of upper and lower laminating, thereby ensuring that the quality of upper and lower laminating is very high. By setting a small shaft portion 3312 on the end face of the other end of the unwinding roller 331, and setting a guiding cone surface 3313 extending to the small shaft portion 3312 on the corner of the other end of the unwinding roller 331, the outer end of the small shaft portion 3312 is also made into a truncated cone end 3314 with a small outer side and a large inner side. This can not only greatly facilitate the installation of the end of the paper roll on the unwinding roller 331, but also reduce the probability of the end of the paper roll being folded during the installation process, which can greatly improve the convenience of installing the protective film roll. By setting a positioning convex ring 3311 on the outer circumferential surface of one end of the unwinding roller 331, it can help the positioning convex ring 3311 to quickly and accurately define the installation position of the protective film roll, thereby improving the convenience and accuracy of the installation and positioning of the protective film roll. By setting the swing positioning mechanism 332, not only can the purpose of accurately and stably positioning the other end of the unwinding roller 331 be achieved, but also the swing positioning mechanism 332 can be prevented from affecting the installation process of the protective film roll.

Such a swing positioning mechanism 332 is very reliable. When the swing rod body 3322 is clamped and positioned by the locking screw 3324 and the limit block 3325, the sleeve hole on the swing rod body 3322 is sleeved on the round table end 3314, which can achieve the purpose of stably positioning the unwinding roller 331. Such a swing positioning mechanism 332 is very reliable. Moreover, such a swing positioning mechanism 332 is very convenient to operate, which helps to improve the convenience of use.

[0048] The other end of the limit rod 3323 can swing in and out of the swinging area of ​​the swinging rod body 3322, and the locking screw 3324 is screwed on the other end of the limit rod 3323.

This can make the unwinding roller 331 rotate very smoothly, thereby helping to improve the reliability and applicability of the longitudinal cutting and slitting equipment.

[0050] like Figures 7 to 9As shown, the frame 31 includes a support frame 311 and a sliding frame 312. The support frame 311 is provided with an adjusting screw rod 313.

The film coating roller pressing assembly 32 is arranged on the support frame 311, one end of the unwinding roller 331 can be rotatably arranged on the sliding frame 312, and the swing positioning mechanism 332 is arranged on the sliding frame 312. In this way, the purpose of adjusting the position of the unwinding roller 331 can be achieved, which can not only achieve the processing and assembly errors of the trimming components, but also facilitate the matching of the position of the steel coil, so as to better meet the needs of actual use.

[0051] like Fig. 9 As shown, the sliding frame 312 and the supporting frame 311 are arranged to slide horizontally via a linear slide rail 3121 , which can meet the requirements of stable assembly and sliding.

[0052] like Figure 7 As shown, the coating rolling assembly 32 includes a limit frame 321, a coating lower roller 322, a coating upper roller 323, and at least one lifting hydraulic cylinder 324. The lifting hydraulic cylinder 324 is vertically arranged on the support frame 311. The limit frame 321 can be vertically slidably arranged on the support frame 311, and the limit frame 321 is driven and connected with the lifting hydraulic cylinder 324. The coating lower roller 322 can be rotatably arranged horizontally on the support frame 311. The coating upper roller 323 is horizontally arranged above the coating lower roller 322, and the coating upper roller 323 is rotatably connected with the limit frame 321. The coating upper roller 323 and the coating lower roller 322 are parallel to each other, and the coating upper roller 323 can make reciprocating motion away from and close to the coating lower roller 322 under the drive of the lifting hydraulic cylinder 324. Such a coating roller assembly 32 can not only coat steel coils of different thicknesses, but also adjust the coating pressure, thereby being conducive to obtaining different coating effects, thereby helping to further improve the application scope of the longitudinal cutting and slitting equipment.

[0053] like Figure 8 As shown, one end of the unwinding roller 331 passes through the sliding frame 312, and a counterweight wheel 3315 is mounted on the end of the unwinding roller 331 that passes through the sliding frame 312. When the swing positioning mechanism 332 swings away from the other end of the unwinding roller 331, the counterweight wheel 3315 can offset the gravity exerted on the other end of the unwinding roller 331, so that the unwinding roller 331 can be stably maintained in a horizontal state, thereby reducing the probability of deformation of related components, and further improving the reliability of the longitudinal cutting and slitting equipment.

[0054] like Figure 2 and Fig.10As shown, two edge material take-up devices 61 are arranged on one side of the output end of the longitudinal shearing main machine 6, and the two edge material take-up devices 61 are respectively located on both sides of the steel coil conveying direction, and a guide device 62 is arranged between the two edge material take-up devices 61 and the longitudinal shearing main machine 6; the guide device 62 includes a lifting drive assembly 621, a rectangular guide hole 622, two longitudinal guide rollers 623, and two vertical guide rollers 624. A horizontally penetrating mounting hole 6211 is opened on the movable end of the lifting drive assembly 621, and the two longitudinal guide rollers 623 are arranged side by side and parallel to each other in the mounting hole 6211, and the two vertical guide rollers 624 are arranged side by side and parallel to each other in the mounting hole 6211, and the rectangular guide hole 622 is arranged horizontally through the center of the mounting hole 6211, and the rectangular guide hole 622 passes between the two longitudinal guide rollers 623, and also passes through the two vertical guide rollers 624. The lifting and lowering can be achieved by a cylinder, an oil cylinder, or an electric push rod through the lifting drive assembly 621. The rectangular guide hole 622 can guide the edge material strip cut from the side of the steel coil to accurately enter the edge material winding device 61, and the height position of the rectangular guide hole 622 can be changed by the lifting drive assembly 621, so that the edge material can be evenly and stably rolled up, which can improve the stability of the edge material winding. The rectangular guide hole 622 can make the edge material be constrained by the guide roller in the four directions of up, down, left and right, so that even if the diameter of the edge material roll becomes larger, due to the constraint of the vertical guide roller 624, the edge material can be guided to the edge material winding device 61, so that the edge material is evenly wound along the height direction of the edge material winding device 61, so as to obtain an evenly distributed and tightly wound edge material roll, which is beneficial to the transportation and stacking of the edge material roll, and also beneficial to the stable operation of the edge material winding device 61. Secondly, regardless of the diameter of the edge material coil formed on the edge material winding device 61, the relative angle formed between the edge material and the steel coil is always maintained within a relatively fixed range through the rectangular guide hole 622, that is, within the range defined by the width of the rectangular guide hole 622. In this way, the stretching angle of the edge material on the steel coil can also be kept within a reasonable range, thereby preventing the edge material from exerting excessive pulling force on the steel coil in the width direction, which is beneficial to ensuring that the force on the blade of the edge material cutting tool is balanced, reducing the probability of chipping, and greatly improving the service life of the tool; at the same time, it can also ensure that the edge of the steel coil is sheared smoothly, greatly improving the quality of the steel coil.

[0055] like Figure 1As shown, the first buffer pit 4 is provided with a lifting material guide mechanism 41, and a plurality of first material guide rollers 411 arranged side by side along the conveying direction of the steel coil are arranged on the top surface of the lifting end of the lifting material guide mechanism 41; the pit opening of the second buffer pit 7 is provided with a swinging material guide mechanism 71 that can swing up and down, and a plurality of second material guide rollers 711 arranged side by side along the conveying direction of the steel coil are arranged on the top surface of the swinging end of the swinging material guide mechanism 71. In this way, the steel coil can pass through the first buffer pit 4 and the second buffer pit 7 more smoothly while meeting the buffering requirements, thereby helping to further improve the accuracy and stability of the steel coil transfer, and further helping to further improve the quality of steel coil processing.

[0056] like Figure 1 and Figure 2 As shown, the winding device 20 includes a winding machine 201, a discharge vehicle 202, and a horizontal rotating mechanism 203. At least one horizontal supporting arm 2031 is provided on the horizontal rotating end of the horizontal rotating mechanism 203. The horizontal rotating mechanism 203 is arranged beside the winding machine 201, and the horizontal supporting arm 2031 can be driven by the horizontal rotating mechanism 203 to face the winding machine 201. The discharge vehicle 202 can reciprocate horizontally between the winding machine 201 and the horizontal supporting arm 2031. The discharge vehicle 202 can unload the steel coil from the winding machine 201 and put the steel coil on the horizontal supporting arm 2031. The horizontal rotating mechanism 203 is adopted, and at least one horizontal supporting arm 2031 is provided on the horizontal rotating end of the horizontal rotating mechanism 203. Such a horizontal support arm 2031 can stably take over and stably lift the steel coil directly from the unloading vehicle 202 without using a crane, and then directly carry out packaging operations such as tying straps and covering with waterproof film, and the steel coil is very stable during the packaging process, which can help make the packaging process more convenient and safe, thereby helping to improve the efficiency and safety of steel coil packaging. At the same time, after adopting such a winding device 20, the crane does not need to participate in the packaging process, which does not occupy the time of the crane to transport other items, which can help reduce the inconvenience of enterprise production management. The horizontal rotating mechanism 203 is set up to facilitate the adjustment of the position of the steel coil in a very stable manner, so that the steel coil can be kept away from the winder 201 so that the steel coil is in a relatively open position, which not only facilitates the packaging operation, but also improves the safety of packaging.

[0057] like Figure 2 , Fig.11 and Fig.12As shown, there are three horizontal supporting arms 2031, two of which are respectively located on the left and right side walls of the horizontal rotating end of the horizontal rotating mechanism 203, and another horizontal supporting arm 2031 is located on the front wall of the horizontal rotating end of the horizontal rotating mechanism 203, and the horizontal supporting arm 2031 is arranged vertically with the other two horizontal supporting arms 2031. This not only enables the longitudinal cutting and slitting device to have sufficient supporting capacity, but also avoids mutual influence between the steel coils supported by the three horizontal supporting arms 2031, which helps to further improve the applicability of the longitudinal cutting and slitting device.

[0058] like Fig.12 and Fig.13 As shown, the horizontal support arm 2031 includes two horizontal support rods 2032, one end of each of the two horizontal support rods 2032 is connected to the horizontal rotation end of the horizontal rotation mechanism 203, and the two horizontal support rods 2032 are arranged parallel to each other, and a clearance gap 2033 is reserved between the two horizontal support rods 2032. The use of two horizontal support rods 2032 can have a very stable and reliable supporting capacity; the reserved clearance gap 2033 can provide space for the strapping tape to pass through the inner side of the steel coil, which can facilitate the strapping tape to axially strap the steel coil by passing through the inner hole of the steel coil; thus, it can be convenient to meet more packaging needs, which helps to further improve the applicability of the longitudinal cutting and slitting equipment.

[0059] like Figures 11 to 13 As shown, a detachable support bar 2034 is provided on the top surface of the horizontal support rod 2032. In this way, the support bar 2034 can be used to support the steel coil, and the horizontal support rod 2032 does not need to directly support the steel coil, so the horizontal support rod 2032 will not wear out during use, and when the support bar 2034 wears out, a good support effect can be quickly obtained by replacing the support bar 2034, and the maintenance cost is also very low.

[0060] like Fig.13 As shown, the radial cross section of the support bar 2034 is circular, the bottom surface of the support bar 2034 is a horizontal surface 2035, and the support bar 2034 is horizontally pressed on the top surface of the horizontal support rod 2032 through the horizontal surface 2035. This not only enables the support bar 2034 to have a stronger supporting capacity, but also plays a certain guiding role, so that the steel coil can be more stably and smoothly placed on and off the support bar 2034.

[0061] like Fig.13As shown, the support bar 2034 is provided with a plurality of vertically penetrating countersunk holes 2036 (not shown in the top view), and the countersunk holes 2036 are arranged side by side along the length direction of the support bar 2034. Each countersunk hole 2036 is a countersunk hole with a larger top and a smaller bottom. The countersunk holes 2036 are used to hide the nut end of a screw (not shown in the figure), and the threaded end of the screw passes through the lower end of the countersunk hole 2036 and is screwed to the horizontal support rod 2032. This not only makes the installation and positioning of the support bar 2034 very stable and reliable, but also facilitates disassembly and maintenance.

[0062] like Figures 11 to 13 As shown, the horizontal support rod 2032 is a slat-shaped support rod, and the plate surface of the horizontal support rod 2032 extends vertically. This not only enables the horizontal support rod 2032 to have a stable and reliable supporting capacity, but also controls the amount of material used, and facilitates the insertion of strapping tape at more locations of the inner hole of the steel coil, thereby facilitating the satisfaction of more packaging needs.

[0063] The slat-shaped horizontal support rod 2032 is a steel plate with a thickness of 50 mm, which not only controls the amount of material used, but also enables the horizontal support rod 2032 to have a very stable and reliable bearing capacity.

[0064] like Fig.12 As shown, a reinforcing rib 2037 is arranged between the ends of the two horizontal supporting rods 2032 connected to the horizontal rotating end of the horizontal rotating mechanism 203, and the reinforcing rib 2037 is connected to the horizontal rotating end of the horizontal rotating mechanism 203. The reinforcing rib 2037 can be composed of one plate-shaped reinforcing rib or a plurality of plate-shaped reinforcing ribs. This can help to enhance the installation strength of the two horizontal supporting rods 2032, so that the horizontal supporting arm 2031 can have a stronger supporting capacity. And the end of the reinforcing rib 2037 away from the horizontal rotating mechanism 203 is a horizontal plate-shaped reinforcing rib horizontally arranged on the lower end of the horizontal supporting rod 2032. The arrangement of the reinforcing rib 2037 can avoid adverse effects on the insertion of the strapping tape into the gap 2033.

[0065] like Fig.12 and Fig.13 As shown, the surfaces of the two horizontal support rods 2032 that are separated from each other are respectively provided with horizontally extending reinforcing protrusions 2038. This not only can enhance the structural strength of the horizontal support rods 2032, but also will not occupy the space of the gap 2033, which helps to further improve the reliability and applicability of the longitudinal cutting and slitting equipment.

[0066] like Fig.12 and Fig.13As shown, the outer surface of the reinforcing protrusion 2038 is an arc-shaped convex surface. This not only enables the reinforcing protrusion 2038 to have a reliable reinforcing effect, but also prevents the reinforcing protrusion 2038 from scratching the inner wall of the steel coil, thereby better meeting the needs of actual use.

[0067] like Fig.11 and Fig.12 As shown, the horizontal rotating mechanism 203 includes a positioning seat 204, a driving motor 205, a rotating disk 206, and a rotating shaft 207. The driving motor 205 is arranged on the positioning seat 204, and the rotating shaft 207 is arranged vertically. The lower end of the rotating shaft 207 can be horizontally rotatably embedded in the positioning seat 204, and the lower end of the rotating shaft 207 is drivingly connected to the driving motor 205. The rotating disk 206 is sleeved on the upper end of the rotating shaft 207, and one end of the horizontal supporting arm 2031 is fixed on the outer wall of the rotating disk 206. Such a horizontal rotating mechanism 203 is very simple and reliable, which is not only convenient for manufacturing, but also ensures that the horizontal rotation is very stable, thereby helping to further improve the reliability of the longitudinal shearing and slitting equipment.

[0068] The driving motor 205 is a hydraulic motor, which can make the driving of the driving motor 205 highly stable and reliable. A bearing is arranged between the rotating shaft 207 and the positioning seat 204 to realize the assembly capable of horizontal rotation, which can ensure that the rotation of the rotating shaft 207 is very stable.

[0069] like Fig.11 As shown, a driving gear 2051 is mounted on the power output shaft of the driving motor 205, and a driven gear 2052 is mounted on the lower end of the rotating shaft 207, and the driven gear 2052 is meshed with the driving gear 2051. This can make the transmission connection between the rotating shaft 207 and the driving motor 205 very stable and reliable, thereby helping to improve the accuracy and stability of the rotation of the rotating shaft 207, and further help to further improve the accuracy and stability of the swing of the horizontal supporting arm 2031.

[0070] like Fig.11 As shown, a horizontally arranged thrust ball bearing 208 is embedded between the rotating disk 206 and the positioning seat 204, and the axial center line of the rotating shaft 207 is coaxial with the axial center line of the thrust ball bearing 208. This can not only meet the normal rotation requirements of the rotating disk 206, but also make the horizontal rotation of the rotating disk 206 very stable, and can make the rotating disk 206 have a higher bearing capacity, which helps to further improve the reliability and durability of the longitudinal shearing and slitting equipment.

[0071] like Figure 1 and Figure 2As shown, a weighing device 30 is arranged beside the horizontal rotating mechanism 203, and a supporting notch 301 is provided on the side wall of the weighing device 30 facing the horizontal rotating mechanism 203. A discharging vehicle 40 capable of horizontal reciprocating motion is arranged between the supporting notch 301 and the horizontal rotating mechanism 203, and the discharging vehicle 40 can transfer the steel coil on the horizontal supporting arm 2031 to the supporting notch 301. In this way, the steel coil can be weighed conveniently and safely, which not only facilitates the subsequent management and transportation of the steel coil by the enterprise, but also greatly improves the safety of production.

[0072] like Fig.14 As shown, the weighing device 30 is a floor scale, and the supporting notch 301 is a V-shaped notch opened on the load-bearing part of the floor scale. This can help the weighing device 30 to safely and stably support the steel coil, thereby further improving the safety and stability of weighing.

[0073] like Figure 1 and Fig.14 As shown, the unloading vehicle 202 and the discharging vehicle 40 include a guide rail 401, a motor-driven traveling vehicle 402, a hydraulic lifting drive assembly 403, and a supporting platform 404. The guide rail 401 is arranged horizontally, the traveling vehicle 402 is slidably embedded on the guide rail 401, the hydraulic lifting drive assembly 403 is arranged on the traveling vehicle 402, the supporting platform 404 is arranged on the lifting end of the hydraulic lifting drive assembly 403, and a V-shaped drag groove 4041 for supporting the steel coil is provided on the top surface of the supporting platform 404. Such unloading vehicle 202 and discharging vehicle 40 are very stable and reliable, which can greatly improve the accuracy and stability of the steel coil transfer, thereby better meeting the needs of actual use.

[0074] like Figure 2As shown, the winder 201 has a horizontally arranged winding shaft 2011, and one end of the winding shaft 2011 is suspended; when winding, the outer end of the winding shaft 2011 is held by a swinging lifting mechanism 2012; when unloading, the swinging lifting mechanism 2012 swings open to make room for the steel coil to horizontally leave the winding shaft 2011; the unloading cart 202 is an unloading cart that can move horizontally and can be lifted and lowered, so the unloading cart 202 can change the horizontal position and height position of the steel coil. The unloading car 202 is arranged between the horizontal rotating mechanism 203 and the coiler 201, and enables the unloading car 202 to perform horizontal reciprocating motion between the horizontal rotating mechanism 203 and the coiler 201; in the initial state, the horizontal supporting arm 2031 faces the direction of the unloading car 202; after the coiler 201 completes coiling, the steel coil is initially bundled with a strapping belt; then the unloading car 202 is used to support the steel coil and remove the steel coil from the coiler 201 by horizontal movement; then the unloading car 202 is used to put the steel coil on the horizontal supporting arm 2031; then the unloading car 202 is separated from the steel coil, and the horizontal rotating mechanism 203 is started to horizontally move the steel coil to a relatively open position for packaging operation. In this way, the packaging operation can be conveniently performed and the packaging safety can be improved. The operating principle of the unloading trolley 40 is similar to that of the unloading trolley 202. The unloading trolley 40 lifts the steel coil on the horizontal supporting arm 2031 through lifting movement; then uses horizontal movement to make the steel coil enter above the supporting gap 301; then the unloading trolley 40 uses descending movement to place the steel coil on the supporting gap 301; after the supporting platform 404 of the unloading trolley 40 is completely separated from the steel coil, the weighing device 30 can be used to weigh the steel coil, which can meet the actual use needs.
