Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.

[0018] Reference Figures 1-4 This utility model discloses a steel strip uncoiling box, including an uncoiling box body 1 and a material preparation box 2. The material preparation box 2 is fixed to one side of the uncoiling box body 1, and a base plate 3 is fixed to the bottom of the uncoiling box body 1 and the material preparation box 2, and the base plate 3 is fixed to the ground. An uncoiling groove 11 is provided inside the uncoiling box body 1, and the steel strip coil 4 is placed in the uncoiling groove 11. A material stop block 12 is fixed on the side of the uncoiling box body 1 away from the material preparation box 2.

[0019] The material preparation box 2 has a material preparation trough 21. The bottom surface of the material preparation trough 21 is inclined, with the side of the bottom surface of the material preparation trough 21 closer to the uncoiling box body 1 being lower and the side of the material preparation trough 21 further away from the uncoiling box body 1 being higher. The material preparation trough 21 contains spare steel strip coils 4. After the steel strip coils 4 in the uncoiling box body 1 are processed, the spare steel strip coils 4 enter the uncoiling box body 1 along the material preparation trough 21. The bottom surface of the material preparation trough 21 has a receiving groove 22. The receiving groove 22 contains a first rotating shaft 23, which is rotatably connected to the groove wall of the receiving groove 22. One end of the first rotating shaft 23 extends out of the material preparation box 2. The receiving groove 22 contains a baffle 24, which is fixed to the first rotating shaft 23. A first drive assembly 5 for driving the first rotating shaft 23 to rotate is installed on the base plate 3. The first drive assembly 5 drives the first rotating shaft 23 to rotate, thereby causing the baffle 24 to rotate at a certain angle. The baffle 24 forms a certain angle with the bottom surface of the material preparation trough 21. The baffle 24 blocks the spare steel strip coil 4 in the material preparation trough 21, preventing the spare steel strip coil 4 from sliding towards the uncoiling box body 1.

[0020] When the spare steel strip coil 4 needs to enter the uncoiling box body 1, the baffle 24 rotates at a certain angle, and the baffle 24 rotates completely into the receiving groove 22, with the upper surface of the baffle 24 parallel to the bottom surface of the material preparation groove 21. The spare steel strip coil 4 is no longer obstructed and slides into the uncoiling box body 1.

[0021] The first drive assembly 5 includes a first hydraulic cylinder 51 and a rocker arm 52. One end of the rocker arm 52 is fixed to the first rotating shaft 23, and the other end of the rocker arm 52 is hinged to the piston rod of the first hydraulic cylinder 51. The tail of the first hydraulic cylinder 51 is hinged to the base plate 3. When the first hydraulic cylinder 51 retracts, it drives the rocker arm 52 to rotate towards the unwinding box body 1, thereby driving the baffle 24 to rotate into the receiving groove 22.

[0022] The bottom of the uncoiling box body 1 is provided with a first support limiting roller 6 and a second support limiting roller 7. Both the first support limiting roller 6 and the second support limiting roller 7 penetrate the uncoiling box body 1. The steel strip coil 4 inside the uncoiling box body 1 is located between the first support limiting roller 6 and the second support limiting roller 7. The first support limiting roller 6 and the second support limiting roller 7 are in contact with the steel strip coil 4.

[0023] Both ends of the first support and limiting roller 6 are fixed with a first drive shaft 61, and both ends of the first support and limiting roller 6 are provided with a first mounting block 62. The first drive shaft 61 is rotatably connected to the first mounting block 62. Both ends of the second support and limiting roller 7 are fixed with a second drive shaft 71, and both ends of the second support and limiting roller 7 are provided with a second mounting block 72. The second drive shaft 71 is rotatably connected to the second mounting block 72. A second drive assembly 8 is installed on the base plate 3 to drive the first drive shaft 61 and the second drive shaft 71 to rotate in the same direction.

[0024] The second drive assembly 8 includes a first sprocket 81, a second sprocket 82, and a chain 83. One end of the first drive shaft 61 extends out of the first mounting block 62 and is fixed to the first sprocket 81. One end of the second drive shaft 71 extends out of the second mounting block 72 and is fixed to the second sprocket 82. The sprockets mesh with the first sprocket 81 and the second sprocket 82. A motor 84 that drives the second sprocket 82 to rotate is fixed on the base plate 3.

[0025] The bottom of the steel strip coil 4 in the uncoiling box body 1 is located between the first support limiting roller 6 and the second support limiting roller 7. After the steel strip coil 4 in the uncoiling box body 1 has finished processing, the steel strip coil 4 in the material preparation box 2 slides into the uncoiling box body 1. The beginning of the new steel strip coil 4 in the uncoiling box body 1 needs to be welded and fixed to the end of the previous steel strip coil 4. At this time, the motor 84 needs to be started, which drives the first support limiting roller 6 and the second support limiting roller 7 to rotate, thereby driving the steel strip coil 4 in the uncoiling box body 1 to rotate, so that the workers can easily move the beginning end of the steel strip coil 4 to the welding platform.

[0026] The front and rear upper sidewalls of the uncoiling box body 1 are provided with a first through groove 13, a second through groove 14, and a third through groove 15, arranged vertically. An upper side limiting roller 16 is rotatably connected to the groove wall of the first through groove 13, and the top of the steel strip coil 4 is located between the two upper side limiting rollers 16. A lower side limiting roller 17 is rotatably connected to the groove wall of the third through groove 15, and the bottom of the steel strip coil 4 is located between the two lower side limiting rollers 17. The upper side limiting rollers 16 and the lower side limiting rollers 17 effectively prevent the steel strip coil 4 from contacting the inner sidewall of the uncoiling box body 1, thereby reducing the frictional force when the steel strip coil 4 is uncoiled.

[0027] A first fixing block 18 is provided in the second through groove 14, and the first fixing block 18 is fixed to the groove wall of the second through groove 14. A support plate 31 is provided on the base plate 3, and a support leg 32 is fixed to the bottom of the support plate 31. The support leg 32 is fixed to the base plate 3. A support block 33 is slidably connected to the support plate 31, and a second fixing block 34 is fixed to the support block 33. A second hydraulic cylinder 35 that drives the support block 33 to slide is fixed to the support plate 31. A bearing is fixed to the side of the second fixing block 34 near the first fixing block 18. A limit shaft 36 is fixed to the inner ring of the bearing. A connecting hole 181 is provided on the first fixing block 18, and the axis of the limit shaft 36 is aligned with the axis of the connecting hole 181. When the second hydraulic cylinder 35 drives the support block 33 to slide, the limit shaft 36 moves towards the first fixing plate. The limit shaft 36 passes through the connecting hole 181 and is rotatably connected to the first fixing block 18. The limit shaft 36 passes through the center of the steel strip coil 4.

[0028] As the amount of steel strip coil 4 inside the uncoiling box body 1 decreases, the entire steel strip coil 4 may detach from the uncoiling box body 1. To prevent the steel strip coil 4 from detaching from the uncoiling box body 1, a limiting shaft 36 is inserted at the center position of the steel strip coil 4. The limiting shaft 36 is rotatable and will not affect the uncoiling of the steel strip coil 4. Before the spare steel strip coil 4 slides from the material box 2 into the uncoiling box body 1, the second hydraulic cylinder 35 drives the limiting shaft 36 to exit the uncoiling box body 1. When the steel strip coil 4 reaches between the first support limiting roller 6 and the second support limiting roller 7, the second hydraulic cylinder 35 drives the limiting shaft 36 to insert into the connecting hole 181 of the first fixing block 18.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
