Description

Technical Field

[0001] This utility model relates to a conveying device for sheared steel plates on a steel coil slitting and leveling production line, belonging to the field of sheared plate conveying technology. Background Technology

[0002] The steel coil uncoiling, leveling, and slitting production line is used to perform a series of operations such as uncoiling, leveling, and shearing on metal coils leaving the factory, ultimately processing them into sheet metal. (See also...) Figure 1 The main components include a leveling machine 1 and a shearing machine 2. After uncoiling and leveling, the sheet material is longitudinally sheared into narrower strips of the required width by the slitting machine, and then cut to length by the shearing machine 2 into flat sheets of the required length. The shearing machine performs both longitudinal and transverse shearing on the sheet material. Longitudinal shearing refers to cutting along the direction of the sheet material (specifically, slitting and edge trimming) to cut the width of the sheet. Transverse shearing refers to cutting perpendicular to the direction of the sheet material to cut the length of the sheet.

[0003] The existing layout of the steel coil uncoiling, leveling, and slitting production line involves arranging a lifting platform behind the shearing machine 2, onto which the sheared sheet slides. This method causes scratches on the sheet as it slides onto the lifting platform during the shearing machine's cross-cutting, and also prevents automatic stacking and flipping. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing lifting platforms located behind shearing machines by providing a multi-functional conveying device for steel coil slitting and leveling production lines that prevents scratches on sheet metal and features automatic stacking and flipping stacking.

[0005] This utility model relates to a multi-functional conveying device for a steel coil slitting and leveling production line, and adopts the following technical solution:

[0006] The device includes a front conveying device and a rear conveying device arranged in sequence; the front conveying device includes a front conveyor and a front lifting mechanism, with the front conveyor mounted on the front lifting mechanism; the rear conveying device includes a rear conveyor, a rear lifting mechanism, and a stacking mechanism, with the rear conveyor mounted on the rear lifting mechanism, and a stacking mechanism fixedly mounted on the outside of the rear conveyor. The stacking mechanism includes a gantry frame and an alignment mechanism and a tapping mechanism mounted on the gantry frame, with a material turning mechanism mounted on the alignment mechanism and the tapping mechanism.

[0007] The front and rear conveyors have the same structure, including a conveyor frame and a transmission mechanism. The conveyor frame is connected to a lifting mechanism, and idlers are installed on the conveyor frame. At least one idler is connected to the transmission mechanism, and adjacent idlers are connected via an inter-roller chain drive. The transmission mechanism includes a motor, a conveyor shaft, and a drive chain drive. Both the motor and the conveyor shaft are connected to the conveyor frame. The conveyor shaft is connected to the motor's rotating shaft, and the conveyor shaft is connected to at least one idler via a drive chain drive. The motor drives the idler to rotate via the conveyor shaft and chain drive, and the remaining idlers then rotate via chain drive, causing the material placed on the idlers to move accordingly.

[0008] Both the front and rear lifting mechanisms employ lifting cylinders, which can be hydraulic, pneumatic, or electric cylinders. Multiple sets of lifting cylinders can be installed, and each cylinder can be mounted in a pit. The front and rear conveyors (specifically, the conveyor frames on them) are connected to the piston rods of each lifting cylinder. To ensure smooth operation, guide rods are installed on the piston rods of the lifting cylinders.

[0009] The alignment mechanism includes an alignment frame and alignment seats. The alignment frame is mounted on a gantry frame, and the alignment seats are mounted on the alignment frame. Multiple alignment seats are provided on the alignment frame, and one side of the steel plate rests against the alignment seat to achieve alignment.

[0010] The alignment frame is connected to an alignment traverse mechanism mounted on the gantry. The alignment traverse mechanism drives the alignment frame to move on the gantry to adjust its position. The alignment traverse mechanism includes an alignment drive motor and an alignment lead screw mounted on the gantry. One end of the alignment lead screw is connected to the shaft of the alignment drive motor. The alignment frame is provided with a nut that is threadedly connected to the alignment lead screw. The alignment drive motor drives the alignment frame to move through the lead screw and nut pair, adjusting its position according to the width of the steel plate.

[0011] The striking mechanism includes a striking frame, a striking cylinder, and a striking head. The striking frame is mounted on a gantry frame, the striking cylinder is mounted on the striking frame, and the striking head is connected to the piston rod of the striking cylinder. The striking cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The striking head strikes the steel plate by extending and retracting the piston rod of the striking cylinder, aligning the steel plate onto the alignment seat.

[0012] The patting frame is connected to a patting traversing mechanism mounted on the gantry frame. The patting traversing mechanism drives the patting frame to move on the gantry frame to adjust its position. The patting traversing mechanism includes a patting drive motor and a patting screw mounted on the gantry frame. One end of the patting screw is connected to the shaft of the patting drive motor, and the patting frame is provided with a nut that is threadedly connected to the patting screw. The patting drive motor drives the patting frame to move through the screw-nut pair, adjusting its position according to the width of the steel plate.

[0013] The material turning mechanism includes a material turning frame, a material turning roller, and a material turning cylinder. The material turning cylinder is installed on an alignment mechanism (alignment frame) or a slapping mechanism (slapping frame). The material turning frame is hinged to the alignment mechanism (alignment frame) or the slapping mechanism (slapping frame) and connected to the piston rod of the material turning cylinder. The material turning rollers are distributed longitudinally (in the direction of steel plate conveying) on ​​the material turning frame.

[0014] A front conveyor and a rear conveyor are sequentially installed on the discharge side of the shearing machine.

[0015] This utility model can achieve two functions: firstly, the stacking function of slit boards, and secondly, the board material conveying function of cross-cut boards, enabling cross-cut boards to be flipped and stacked, thus improving the board surface quality; it has the following characteristics:

[0016] 1. A front conveyor with lifting function is installed at the outlet of the shearing machine, and rotating rollers are installed on it. When the sheet metal is used for longitudinal and transverse shearing, the lifting roller table can be used as a stacking mechanism to complete the functions of longitudinal and transverse shearing and stacking.

[0017] 2. When the sheet material is only used for cross-cutting, the idler rollers of the front conveyor device rise and rotate, which can be used as idler rollers to transport the cross-cut sheet material to the flipping and stacking stage, thus completing the cross-cutting and stacking function and avoiding scratches on the sheet material.

[0027] like Figure 1 As shown, the multi-functional conveying device for a steel coil slitting and leveling production line of this utility model includes a front conveying device 3 and a rear conveying device 4 arranged sequentially on the discharge side of the shearing machine 2.

[0028] like Figure 2 As shown, the front conveying device 3 includes a conveyor and a lifting mechanism. The conveyor includes a conveying frame 7 and a transmission mechanism 6. The conveying frame 7 is connected to the front lifting mechanism, which uses multiple front lifting cylinders 5 (which can be hydraulic cylinders, pneumatic cylinders, or electric cylinders). Each front lifting cylinder 5 can be installed in a pit, and the conveying frame 7 is connected to the piston rod of each front lifting cylinder 5. To ensure smooth operation, guide rods 11 are provided on the piston rods of the lifting cylinders 5. Parallel idler rollers 10 are installed on the conveying frame 7, and at least one idler roller 10 is connected to the transmission mechanism 6. Adjacent idler rollers 10 are connected through an inter-roller chain drive. The transmission mechanism includes a motor 6, a conveying shaft 8, and a drive chain drive 9. The motor 6 and the conveying shaft 8 are both connected to the conveying frame 7. The conveying shaft 8 is connected to the rotating shaft of the motor 6, and the conveying shaft 8 is connected to one idler roller 10 through the drive chain drive 9. The motor 6 drives the idler roller 10 to rotate through the conveying shaft 8 and the drive chain drive 9, and the remaining idler rollers 10 then rotate through the inter-roller chain drive, causing the material placed on the idler roller 10 to move accordingly.

[0029] like Figure 3 As shown, the rear conveying device 4 includes a rear conveyor 12, a rear lifting mechanism, and a stacking mechanism. The rear conveyor 12 is mounted on the rear lifting mechanism, which employs multiple rear lifting cylinders 13 and is equipped with guide rods 27. The stacking mechanism is fixedly mounted on the outer side of the rear conveyor 12. The stacking mechanism includes a gantry frame 14, an alignment mechanism, and a tapping mechanism. The alignment mechanism is connected to the alignment transverse movement mechanism, and the tapping mechanism is connected to the tapping transverse movement mechanism to achieve position adjustment of the alignment and tapping mechanisms. Both the alignment transverse movement mechanism and the tapping transverse movement mechanism are located on the upper part of the gantry frame 14. Opposite turning mechanisms are provided on the alignment and tapping mechanisms.

[0030] The alignment mechanism includes an alignment frame 18 and alignment seats 15. The alignment frame 18 is connected to the alignment transverse movement mechanism, which drives the alignment frame 18 to move on the gantry frame 14 to adjust its position. Multiple alignment seats 15 are provided on the alignment frame 18, and one side of the steel plate rests against the alignment seat 15 to achieve alignment.

[0031] The alignment and traversing mechanism includes an alignment drive motor 17 and an alignment lead screw 19 mounted on the upper part of the gantry frame 14. One end of the alignment lead screw 19 is connected to the shaft of the alignment drive motor 17, and a nut threadedly connected to the alignment lead screw 19 is provided on the alignment frame 18. The alignment drive motor 17 drives the alignment frame 18 to move through the lead screw and nut pair, adjusting its position according to the width of the steel plate.

[0032] The slapping mechanism includes a slapping frame 23, a slapping cylinder 25, and a slapping head 26. The slapping frame 23 is connected to a slapping lateral movement mechanism, which drives the slapping frame 23 to move on the gantry frame 14 to adjust its position. The slapping cylinder 25 is mounted on the slapping frame 23, and the slapping head 26 is connected to the piston rod of the slapping cylinder 25. The slapping cylinder 25 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The slapping head 26 slaps the steel plate by extending and retracting the piston rod of the slapping cylinder 25, aligning the steel plate onto the alignment seat 15.

[0033] The tackling and lateral movement mechanism includes a tackling drive motor 22 and a tackling screw 24 mounted on the gantry frame 14. One end of the tackling screw 24 is connected to the shaft of the tackling drive motor 22, and a nut is provided on the tackling frame 23 that is threadedly connected to the tackling screw 24. The tackling drive motor 22 drives the tackling frame 23 to move through the screw and nut pair, and its position is adjusted according to the width of the steel plate.

[0034] The material turning mechanism is mounted on the alignment frame 18 and the striking frame 23, with the turning mechanisms on the alignment frame 18 and the striking frame 23 arranged opposite to each other. The turning mechanism includes a turning frame 20, turning rollers 16, and a turning cylinder 21. The turning cylinder 21 is mounted on the striking frame 23 (or the alignment frame 18), and the turning frame 20 is hinged to the striking frame 23 (or the alignment frame 18) and connected to the piston rod of the turning cylinder 21. The turning rollers 16 are distributed longitudinally (in the steel plate conveying direction) on the turning frame 20.

[0035] The operation process of the above-mentioned device is as follows.

[0036] 1. When the sheet metal is being slitting or transverse shearing, the sheet metal cut by the shearing machine falls onto the idler rollers 10 in the front conveyor device 3. The front lifting cylinder 5 controls the raising and lowering of the idler rollers 10 in the front conveyor device 3 to adjust the receiving height. As the material falls, the idler rollers 10 descend, which can be used as a stacking mechanism to achieve the functions of slitting, transverse shearing, and stacking.

[0037] 2. When the sheet material is only used for cross-cutting, the conveyor in the front conveying device 3 is raised and lowered by the front lifting cylinder 5 so that the idler roller 10 of the conveyor in the front conveying device 3 is at the same height as the turning roller 16 in the front conveying device 4. The idler roller 10 rotates to transport the cross-cut sheet material to the turning roller 16.

[0038] By activating the alignment drive motor 17 and the patting drive motor 22, the positions of the patting frame 23 and the alignment frame 18 are adjusted so that both sides of the steel plate can be placed on the turning rollers 16 on the patting frame 23 and the alignment frame 18.

[0039] After the steel plate enters the turning roller 16 via the conveyor in the front conveyor device 3, the piston rod of the turning cylinder 21 extends, pushing the turning frame 20 and the turning roller 16 on it to swing downwards. The steel plate falls off the turning roller 16 and lands on the conveyor in the rear conveyor device 4 below.

[0040] The striking cylinder 25 drives the striking head 26 to extend, pushing the steel plates to the alignment seat 15 to achieve the function of cross-cutting and stacking, avoiding scratches on the plates. After the steel plates are stacked to a certain height, the control frame lowers to the bottom, and the conveyor in the conveying device 4 is started to transport the steel plates out.
