Description

Technical Field

[0001] The utility model relates to the field of uncoilers, in particular to a double-station cutting production line. Background Art

[0002] The uncoiler is a specialized machine for leveling metal sheets. It is used to level uneven steel sheets and can be configured to form an uncoiler, leveling, shearing line, or other sheet product production lines. It is suitable for use in industries such as machinery, vehicles, metal products, household appliances, steel structures, and decoration.

[0003] A search revealed Chinese patent application number CN111085566A, which discloses an internal expansion uncoiler. The patent comprises a support base with a bearing support seat mounted on the support base. The uncoiler head is secured to the bearing support seat via a rotating bearing support system. The working side of the uncoiler head extends beyond the vertical surface of the support base. Several arc-shaped clips extend outward from the working surface of the uncoiler head. These arc-shaped clips are mounted on an expansion drive via a connecting rod mechanism. The expansion drive is a screw drive mechanism with a slider hinged to the connecting rod mechanism. The expansion drive mechanism rotates the connecting rod mechanism, thereby driving the arc-shaped clips to expand outward or retract inward. This simple structure raises the steel strip coil through internal tensioning motion, improving the reliability of the uncoiler.

[0004] However, in actual use, when the weight of the coil is large, the coil is simply tightened and fixed on the unwinding machine body by the expansion device, which still leads to insufficient stability of the coil placement and needs further improvement. Utility Model Content

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] A double-station cutting production line, such as Figure 1 and Figure 2 As shown, it includes a conveyor platform 1, and an uncoiler 2, a longitudinal cutting mechanism 3 and a transverse cutting mechanism 4 are sequentially arranged along the conveying direction of the conveyor platform 1. The coil 12 is placed on the uncoiler 2 to be continuously conveyed forward after unwinding. When passing through the longitudinal cutting mechanism 3, longitudinal cutting is achieved on both sides to achieve the required width, and then the coil 12 is cut to the required length through the transverse cutting mechanism 4. The longitudinal cutting and transverse cutting processing are simultaneously completed while the coil 12 is unwound, thereby effectively improving production efficiency.

[0029] like Figure 1As shown, the uncoiler 2 includes a frame 5, which is rotatably connected to a support shaft 6, and a placement groove 7 for placing the coil 12 is formed between adjacent support shafts 6. The width of the placement groove 7 is smaller than the outer diameter of the inner core of the coil to prevent the coil 12 from falling. A driving source 8 is provided at the bottom of the frame 5, and the driving source 8 is a driving motor. A sprocket 9 is provided on the output end of the driving motor and the support shaft 6. The transmission is achieved through a chain 10 between each sprocket 9. A tensioning block 11 is also provided on the frame 5 to tension the chain 10, ensuring that the chain 10 is in a tensioned state to maintain good transmission. In this way, the support shaft 6 can be driven to rotate by the driving motor, and the rotating support shaft 6 drives the coil 12 to roll to realize the material discharge operation. Moreover, such a support structure for placing the coil 12 can meet the placement of coils 12 with different outer diameters, and has good placement stability and is not prone to shaking.

[0030] like Figure 1 As shown, a limit column 13 for guiding and limiting the end of the coil 12 is also provided on the frame 5. The limit column 13 is located between two adjacent support shafts 6. The height of the limit column 13 is slightly lower than the support shaft 6. With the help of the limit column 13, the end of the coil 12 can be guided to a certain extent to avoid the end of the coil 12 from curling upward when it is retracted or released. With the help of the limit column 13, its end can be transported forward horizontally.

[0031] like Figure 1 As shown, two adjacent support shafts 6 form a placement station for placing the coil 12. There are at least two placement stations. In this embodiment, there are two placement stations. The two placement stations are arranged in sequence along the conveying direction of the conveyor platform 1, so that the uncoiler 2 can place two groups of coils 12 at the same time. In actual use, they can be switched and adjusted as needed to meet more actual production needs and improve corresponding production efficiency.

[0032] like Figure 1 and Figure 2As shown, the longitudinal cutting mechanism 3 includes a chassis 14, a base 15 and a longitudinal cutting knife. Two longitudinal cutting knives are symmetrically arranged. The longitudinal cutting knife includes a knife seat 16 and a knife body 17. The knife body 17 is vertically slidably connected to the knife seat 16, and a power source 18 is provided on the knife body 17 to drive it to rotate to achieve cutting. The power source 18 is a motor and drives the knife body 17 to rotate. A first cylinder 19 is provided on the top of the knife seat 16 to drive the knife body 17 to rise and fall vertically. In this way, when longitudinal cutting is required, the knife body 17 is driven downward by the first cylinder 19, and then the knife body 17 rotates under the action of the power source 18. In the process of conveying the coil 12 forward, the longitudinal cutting is achieved under the action of the cutter body 17, so that the width of the coil 12 can meet the production needs; in addition, a driving roller is provided on the side of the base 15 close to the uncoiler 2, and the driving roller is distributed up and down and is rotatably connected to the base 15. The driving roller includes an active roller 20 and a driven roller 21. The coil 12 passes between the active roller 20 and the driven roller 21. When the active roller 20 continuously rotates, the coil 12 is further driven to be conveyed forward. In addition, a meter 22 for calculating and measuring the length of the coil 12 is provided at the end of the uncoiler 2.

[0033] like Figure 1 and Figure 2 As shown, the knife seat 16 is horizontally slidably connected to the base 15, and the sliding direction of the knife seat 16 is perpendicular to the conveying direction of the coil 12. A guide rail 23 is provided on the base 15 for the knife seat 16 to slide with, and a screw rod 24 is also rotatably connected to the base 15. The screw rod 24 passes through the knife seat 16 and is threadedly connected to it. One end of the screw rod 24 passes through the base 15 and is fixedly provided with a hand wheel 25. In this way, by rotating the hand wheel 25, the knife seat 16 can be driven to move horizontally to achieve position adjustment. The screw rod 24 and the knife seat 16 are set in a one-to-one correspondence, so that the two knife seats 16 can be independently adjusted. Then, in the actual cutting process, the position of the longitudinal cutting knife can be adjusted as needed, and the coils 12 of different widths can be cut to meet the processing needs, which has better applicability.

[0034] like Figure 1 and Figure 2 As shown, the base 15 is horizontally slidably connected to the base frame 14, and the sliding direction of the base 15 is perpendicular to the conveying direction of the coil 12. The sliding base 15 can realize synchronous adjustment of the positions of the two knife seats 16. When the unwound coil 12 is not in the conveying center, the purpose of correction compensation can be achieved, and the comprehensiveness of the longitudinal cutting knife position adjustment is further improved, which is more practical. The sliding drive method of the base 15 can also be achieved by a screw or a cylinder.

[0035] like Figure 1As shown, the cross-cutting mechanism 4 includes a body 26 and a cross-cutting knife. The cross-cutting knife is vertically slidably connected to the body 26, and a second cylinder is provided on the body 26 to drive the cross-cutting knife to rise and fall vertically. When the coil 12 is transported to the cross-cutting mechanism 4 and meets the length requirements, the second cylinder drives the cross-cutting knife to descend and cut the coil 12 to achieve horizontal cutting, and finally obtain a coil body of the required width and length.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
