Abstract
Description
Technical Field
[0001] This utility model relates to a material handling device for uncoiling steel coils, belonging to the field of steel coil uncoiling technology. Background Technology
[0002] Steel coils produced by steel mills are typically processed into steel plates by a slitting and leveling production line. After being unrolled by a slitting machine, the coils are then cut to specific widths by a slitting machine. The equipment used in this production line generally includes an uncoiler, a clamping device, a pre-aligning machine, a trimming shear, a web-aligning device, and a slitting machine. The steel coils first need to be uncoiled by the uncoiler; before entering the uncoiler, the binding steel straps on the coils need to be removed. Then, a material handling device lifts the head of the steel coil and rotates it.
[0003] The existing material handling device uses a swing-type structure for both the material handling roller and the pressure head roller. Its pressure point is unreasonable, operation is inconvenient, and space is limited. The shovel head adopts a flat shovel method, which makes it inconvenient to lift the material head and cannot effectively cooperate with the pressure head roller to flatten the material head. Summary of the Invention
[0004] This invention addresses the shortcomings of existing steel coil uncoiling and feeding devices by providing a direct-pressure uncoiling feeding device that offers accurate pressure points, stable and efficient feeding, and high efficiency.
[0005] The unwinding direct-pressure feeding device of this utility model adopts the following technical solution:
[0006] The device includes a shovel head mechanism and a material handling mechanism. The shovel head mechanism is mounted on a shovel head frame, and the material handling mechanism is mounted on a material handling frame. The material handling mechanism includes a shovel head, a shovel head telescopic mechanism, and a shovel head swing mechanism. The shovel head is mounted on the shovel head telescopic mechanism, and the shovel head telescopic mechanism is connected to the shovel head swing mechanism. The material handling mechanism includes a direct pressing mechanism and a material handling mechanism, both of which are mounted on the material handling frame.
[0007] The shovel head frame and the material handling frame are an integrated structure.
[0008] The shovel head telescopic mechanism includes a shovel head housing and a telescopic mechanism. The shovel head housing is hinged to the shovel head frame, and the telescopic mechanism is disposed inside the shovel head housing. The shovel head is connected to the power output end of the telescopic mechanism. The telescopic mechanism employs a telescopic cylinder, and the shovel head is connected to the piston rod of the telescopic cylinder. The telescopic cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The telescopic cylinder extends or retracts the shovel head by extending or retracting its piston rod.
[0009] The end of the shovel head is equipped with a shovel blade to facilitate cutting the steel coil packing straps and shoveling up the end of the steel coil.
[0010] The shovel head swing mechanism is a swing cylinder, which is hinged to the shovel head frame. Its piston rod is hinged to the shovel head telescopic mechanism (specifically, the shovel head housing). The swing cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The piston rod of the swing cylinder drives the shovel head telescopic mechanism (shovel head housing) to rotate to the steel coil.
[0011] The direct pressure mechanism includes a direct pressure cylinder, a direct pressure seat, and a pressure head roller. The direct pressure cylinder is mounted on the material handling frame, the direct pressure seat is connected to the piston rod of the direct pressure cylinder, and the pressure head roller is mounted on the direct pressure seat. A direct pressure guiding mechanism is provided between the direct pressure seat and the material handling frame. The direct pressure guiding mechanism can be a guide rail mounted on the material handling frame, with the direct pressure seat mounted on the guide rail and connected to the piston rod of the direct pressure cylinder. Alternatively, the guiding mechanism can be a guide shaft mounted on the direct pressure seat, with a guide sleeve mounted on the material handling frame. The guide shaft extends into the guide sleeve and moves up and down with the direct pressure seat, providing a guiding function. The direct pressure cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The direct pressure cylinder drives the direct pressure seat and the pressure head roller to move up and down through its piston rod, causing the pressure head roller to press against the steel coil.
[0012] The direct pressure mechanism is mounted on the transverse movement mechanism to adjust the direct pressure position. The transverse movement mechanism includes a transverse movement cylinder and a transverse movement seat. The transverse movement cylinder is mounted on the material handling frame, and the transverse movement seat is mounted on the material handling frame via a guide rail and connected to the piston rod of the transverse movement cylinder. The direct pressure mechanism is mounted on the transverse movement seat. The transverse movement cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. Its piston rod drives the transverse movement seat to move laterally on the material handling frame, thereby adjusting the position of the direct pressure mechanism (pressure head roller).
[0013] The material handling mechanism includes a material handling cylinder, a material handling seat, a passive material handling roller, a driving material handling roller, and a material handling power mechanism. The material handling cylinder is mounted on the material handling frame, and the material handling seat is connected to the piston rod of the material handling cylinder. The passive material handling roller and the driving material handling roller are mounted on the material handling seat, and the driving material handling roller is connected to the material handling power mechanism. The material handling power mechanism includes a drive motor and a chain drive mechanism. The driving sprocket in the chain drive mechanism is mounted on the shaft of the drive motor, and the passive sprocket is mounted on the driving material handling roller. A material handling guide mechanism is provided between the material handling seat and the material handling frame. The material handling guide mechanism can be a guide rail mounted on the material handling frame, with the material handling seat mounted on the guide rail and connected to the piston rod of the material handling cylinder; alternatively, the material handling guide mechanism can be a guide shaft mounted on a pressure seat, with a guide sleeve mounted on the material handling frame. The guide shaft extends into the guide sleeve and moves up and down with the material handling seat, providing a guiding function. The material handling cylinder can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The piston rod of the feeding cylinder extends and drives the passive and active feeding rollers to move down and press on the steel coil. The active feeding roller drives the steel coil to rotate. During the rotation, the end of the steel coil is lifted by the shovel head, causing the steel coil to unfold.
[0014] The material handling mechanism drives the steel coil to rotate, the shovel head swing mechanism drives the shovel head telescopic mechanism to swing onto the steel coil, the shovel head telescopic mechanism drives the shovel head to extend, cut the steel coil packing strap, and make it easy to pry open the end. The direct pressure mechanism presses on the unfolded steel coil, making it unfold flat and smooth.
[0015] This utility model has the following features:
[0016] 1. The shovel head has a straight-top structure and is telescopic, which can better cooperate with the pressing roller to flatten the arc of the steel coil end; the swinging of the shovel head can more easily cut the steel coil packing strap and make it easier to pry open the end.
[0017] 2. The pressure roller adopts a direct pressure structure, which can be adjusted laterally, has a larger lifting stroke, and can reach the pressure point more accurately.
[0018] 3. The feeding roller adopts a direct pressure structure to ensure that the feeding roller is always pressed on the center of the steel coil, resulting in more reasonable force distribution. The double roller arrangement improves the wrapping effect between the feeding roller and the steel coil. Attached Figure Description

[0022] The unwinding direct-pressure feeding device of this utility model, such as Figure 1 and Figure 2 As shown, the system includes a shovel mechanism and a material-collecting mechanism. The shovel mechanism is mounted on a shovel frame 1, and the material-collecting mechanism is mounted on a material-collecting frame 6. The shovel frame 1 and the material-collecting frame 6 can be an integral structure. The material-collecting mechanism includes a shovel head 5, a shovel head telescopic mechanism, and a shovel head swinging mechanism. The shovel head 5 is mounted on the shovel head telescopic mechanism, which is connected to the shovel head swinging mechanism. The material-collecting mechanism includes a direct-pressing mechanism and a material-collecting mechanism. The material-collecting mechanism drives the steel coil 17 to rotate. The shovel head swinging mechanism drives the shovel head telescopic mechanism to swing onto the steel coil 17. The shovel head telescopic mechanism drives the shovel head 5 to extend, cutting the packing strap of the steel coil 17 and prying open the end. The direct-pressing mechanism presses down on the unfolded steel coil 17, making it unfold smoothly and evenly.
[0023] The shovel head telescopic mechanism includes a shovel head housing 4, a shovel head 5, and a telescopic mechanism. The shovel head housing 4 is hinged to the shovel head frame 1, the telescopic mechanism is housed inside the shovel head housing 4, and the shovel head 5 is connected to the power output end of the telescopic mechanism. The telescopic mechanism uses a telescopic cylinder 3, which can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

The shovel head 5 is connected to the piston rod of the telescopic cylinder 3, and a shovel blade is provided at the end of the shovel head 5 to cut the steel coil packing strap and lift the end of the steel coil 17. The telescopic cylinder 3 extends or retracts the shovel head 5 by extending or retracting its piston rod.
[0024] The shovel head swing mechanism uses a swing cylinder 2, which can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The swing cylinder 2 is hinged to the shovel head frame 1, and its piston rod is hinged to the shovel head housing 4. When the piston rod of the swing cylinder 2 extends, it pushes the shovel head housing 4 to rotate to the steel coil 17. Then, the telescopic cylinder 3 drives the shovel head 5 to extend through its piston rod, cutting the packing strap of the steel coil. When the steel coil 17 rotates, the shovel head 5 picks up its end.
[0025] The direct pressure mechanism includes a direct pressure cylinder 7, a direct pressure seat 14, and a pressure roller 8. The direct pressure cylinder 7, mounted on the material handling frame 6, can be a hydraulic cylinder, pneumatic cylinder, or electric cylinder. The direct pressure seat 14 is connected to the piston rod of the direct pressure cylinder 7, and the pressure roller 8 is mounted on the direct pressure seat 14. The direct pressure cylinder 7 drives the direct pressure seat 14 and the pressure roller 8 to move up and down via its piston rod, causing the pressure roller 8 to press against the steel coil 17. To ensure smooth operation of the pressure roller 8, a direct pressure guide mechanism is provided between the direct pressure seat 14 and the material handling frame 6. The direct pressure guide mechanism can be a guide rail mounted on the material handling frame 6, with the direct pressure seat 14 mounted on the guide rail and connected to the piston rod of the direct pressure cylinder 7. Alternatively, the guide mechanism can be a guide shaft mounted on the direct pressure seat 14, with a guide sleeve mounted on the material handling frame 6. The guide shaft extends into the guide sleeve and moves up and down with the direct pressure seat 14, providing a guiding function.
[0026] To facilitate the adjustment of the lateral position of the pressure roller 8, a lateral movement mechanism is provided on the material handling frame 6, including a lateral movement cylinder 15 and a lateral movement seat 16. The lateral movement cylinder 15 is mounted on the material handling frame 6, and the lateral movement seat 16 is mounted on the material handling frame 6 via a guide rail and connected to the piston rod of the lateral movement cylinder 15. The direct pressure cylinder 7 in the direct pressure mechanism is mounted on the lateral movement seat 16. A direct pressure guide mechanism is provided between the direct pressure seat 14 and the lateral movement seat 16. The lateral movement cylinder 15 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. Its piston rod drives the lateral movement seat 16 to move laterally on the material handling frame 6, thereby realizing the position adjustment of the direct pressure mechanism (including the direct pressure cylinder 7, the direct pressure seat 14, and the pressure roller 8).
[0027] The material handling mechanism includes a material handling cylinder 9, a material handling seat 10, a passive material handling roller 11, a driving material handling roller 12, and a material handling power mechanism 13. The material handling cylinder 9 is mounted on the material handling frame 6 and can be a hydraulic cylinder, pneumatic cylinder, or electric cylinder. The material handling seat 10 is connected to the piston rod of the material handling cylinder 9. The passive material handling roller 11 and the driving material handling roller 12 are mounted on the material handling seat 10. The driving material handling roller 12 is connected to the material handling power mechanism 13. The material handling power mechanism 13 includes a drive motor and a chain drive mechanism. The driving sprocket in the chain drive mechanism is mounted on the shaft of the drive motor, and the passive sprocket 18 is mounted on the driving material handling roller 12 (see [link]). Figure 2 The piston rod of the picking cylinder 9 extends, driving the picking seat 10, the passive picking roller 11, and the active picking roller 12 to move downwards and press against the steel coil 17. The drive motor drives the active picking roller 12 to rotate via a chain transmission mechanism, which in turn drives the steel coil 17 to rotate. When the end of the steel coil 17 rotates to the shovel head 5, it is scooped up by the shovel head 5, causing the steel coil 17 to unfold. The pressure roller 8 presses down on the unfolded steel coil 17 to make it flat. To ensure smooth up-and-down movement of the picking seat 10, a picking guide mechanism is provided between the picking seat 10 and the picking frame 6. The picking guide mechanism can be a guide rail set on the picking frame 6, with the picking seat 10 set on the guide rail and connected to the piston rod of the picking cylinder 9. Alternatively, the picking guide mechanism can be a guide shaft set on the picking seat 10, with a guide sleeve set on the picking frame 6. The guide shaft extends into the guide sleeve and moves up and down with the picking seat 10, serving a guiding function.
