Description

Technical Field

[0001] This utility model relates to the field of metal sheet roll feeding, and in particular to a metal sheet feeding machine. Background Technology

[0002] Metal sheets (such as steel, aluminum, and copper) are typically rolled into rolls after production for long-distance transport. Upon arrival at the factory, these rolls are first unrolled using a specialized unwinding machine. Therefore, the unwinding machine is a crucial component of the metal sheet processing production line, usually used in conjunction with subsequent equipment such as stamping, shearing, and bending to achieve automated production. However, during metal sheet processing, the unwinding machine needs to be intermittently started and stopped to match the production rhythm of subsequent processing equipment. Currently, when the unwinding machine stops, the drive motor that powers the unwinding rack is in a temporary state. Due to its inertia, the metal coil mounted on the rack continues to rotate even after the motor stops, resulting in continuous unwinding even when the machine is stopped. This disrupts the normal operation of subsequent production equipment, and the continued rotation of the unwinding rack also has a reaction effect on the drive motor, negatively impacting its performance. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding machine for metal sheets, which solves the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a metal sheet feeding machine, comprising a frame, a horizontal rotating cylinder rotatably mounted on the frame, and a drive motor for driving the rotating cylinder to rotate at the top of the frame; both ends of the rotating cylinder extend to the outside of the frame, one end of the rotating cylinder is provided with a feeding rack for mounting a metal sheet roll, and the other end of the rotating cylinder is fixedly fitted with a brake disc; a brake seat is fixedly mounted on the frame near the brake disc, a first brake pad is fixedly mounted on one side of the brake seat, and a brake cylinder is fixedly mounted on the outside of the brake seat away from the first brake pad, the telescopic end of the brake cylinder extends into the interior of the brake seat and is fixedly mounted with a second brake pad corresponding to the first brake pad, and one end of the brake disc extends into the interior of the brake seat and is located between the first brake pad and the second brake pad.

[0006] Furthermore, a speed reducer is fixedly installed on the top of the frame, the drive motor is fixedly installed on the speed reducer and its drive shaft is connected to the input end of the speed reducer, and the output end of the speed reducer is connected to the rotating cylinder drive.

[0007] Furthermore, the output end of the reducer is provided with a drive gear, and the rotating shaft is fitted with a driven gear that meshes with the drive gear.

[0008] Furthermore, the frame is provided with a protective cover on the outside of the driving gear and the driven gear.

[0009] Furthermore, the feeding rack includes a sliding sleeve slidably fitted outside the rotating shaft cylinder. Multiple first connecting seats are uniformly fixedly arranged circumferentially on the outer peripheral wall of the sliding sleeve. Multiple pairs of connecting struts are hinged to each first connecting seat at uniform intervals. The other ends of the multiple pairs of connecting struts hinged to the same first connecting seat are respectively hinged to a second connecting seat. An arc-shaped support plate is fixedly arranged on the outer side of each second connecting seat. A limiting disc is fixedly fitted on the rotating shaft cylinder at the position between the driven gear and the sliding sleeve. Multiple limiting grooves, the same number as the number of second connecting seats, are uniformly opened circumferentially on the limiting disc. The end of each second connecting seat near the frame slides in cooperation with each limiting groove on the limiting disc. A limiting head is fixedly arranged on both sides of the limiting disc at each second connecting seat.

[0010] Furthermore, a horizontal hydraulic cylinder is fixedly installed on the side of the brake disc away from the frame. The telescopic rod of the hydraulic cylinder passes through the rotating shaft and has a connector at its end. The connector is fixedly connected to the end of the sliding sleeve away from the frame.

[0011] Furthermore, a hydraulic station for providing power to the hydraulic cylinder is fixedly installed at the bottom of the frame, and the hydraulic cylinder is connected to the hydraulic oil pipeline of the hydraulic station through a rotary joint.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] When applied to a metal sheet processing production line, this invention allows the brake cylinder to extend and engage with the first brake pad to clamp the brake disc, causing it to stop rotating immediately. As the brake disc stops rotating, the rotating shaft and the feeding rack on it also stop rotating synchronously. This prevents the feeding rack from continuing to feed material after the machine stops, facilitating coordination with the intermittent start-stop cycle of subsequent metal sheet processing equipment, ensuring the normal operation of the metal sheet processing production line, and reducing adverse effects on the feeder's drive motor.

[0021] like Figures 1-5 As shown, a metal sheet feeding machine includes a frame 1, on which a horizontal rotating cylinder 2 is rotatably mounted, and a drive motor 3 for driving the rotating cylinder 2 to rotate is mounted on the top of the frame 1. The two ends of the rotating cylinder 2 extend to the outside of the frame 1.

[0022] In this embodiment, a reducer 4 is fixedly mounted on the top of the frame 1, and the drive motor 3 is fixedly mounted on the reducer 4 with its drive shaft connected to the input end of the reducer 4. The output end of the reducer 4 is connected to the rotating shaft cylinder 2 via a transmission connection. Specifically, a drive gear 5 is mounted on the output end of the reducer 4, and a driven gear 6 meshing with the drive gear 5 is fitted on the rotating shaft cylinder 2. In this embodiment, the output power of the drive motor 3 is amplified by the reducer 4 to increase torque, and then the rotating shaft cylinder 2 is driven to rotate through the meshing transmission action of the drive gear 5 and the driven gear 6.

[0023] The frame 1 is equipped with a protective cover 7 on the outside of the driving gear 5 and the driven gear 6. The protective cover 7 serves to shield and protect the driving gear 5 and the driven gear 6, preventing external dust and other impurities from accumulating on the gears. In addition, it can prevent workers from accidentally coming into contact with the rotating gears, reducing safety hazards.

[0024] One end of the rotating shaft cylinder 2 is provided with a feeding rack for mounting and fixing the metal sheet roll, and the other end of the rotating shaft cylinder 2 is fixedly fitted with a brake disc 8. A brake seat 9 is fixedly installed on the frame 1 near the brake disc 8. A first brake pad 10 is fixedly installed on one side of the brake seat 9, and a brake cylinder 11 is fixedly installed on the outside of the brake seat 9 away from the first brake pad 10. The telescopic end of the brake cylinder 11 extends into the interior of the brake seat 9 and is fixedly installed with a second brake pad 12 corresponding to the first brake pad 10. One end of the brake disc 8 extends into the interior of the brake seat 9 and is located between the first brake pad 10 and the second brake pad 12, with the first brake pad 10 close to the corresponding side of the brake disc 8.

[0025] When applied to a metal sheet processing production line, this invention allows the brake cylinder to extend and engage with the first brake pad to clamp the brake disc, causing it to stop rotating immediately. As the brake disc stops rotating, the rotating shaft and the feeding rack on it also stop rotating synchronously. This prevents the feeding rack from continuing to feed material after the machine stops, facilitating coordination with the intermittent start-stop cycle of subsequent metal sheet processing equipment, ensuring the normal operation of the metal sheet processing production line, and reducing adverse effects on the feeder's drive motor.

[0026] In this example, the feeding rack includes a sliding sleeve 13 that is slidably fitted onto the outside of the rotating shaft cylinder 2. Multiple first connecting seats 14 are uniformly fixedly installed circumferentially on the outer peripheral wall of the sliding sleeve 13. Multiple pairs of connecting struts 15 are hingedly installed at uniform intervals on each of the first connecting seats 14. The other ends of the multiple pairs of connecting struts 15 hinged to the same first connecting seat 14 are respectively hinged to a second connecting seat 16. A support plate 17 with an arc-shaped cross-section is fixedly installed on the outer side of each second connecting seat 16. A limiting disk 18 is fixedly fitted onto the rotating shaft cylinder 2 at the position between the driven gear 6 and the sliding sleeve 13. Multiple limiting grooves 19, the same number as the second connecting seats 16, are uniformly opened circumferentially on the limiting disk 18. The end of each second connecting seat 16 near the frame 1 slides in cooperation with each of the limiting grooves 19 on the limiting disk 18. A limiting head 20 is fixedly installed on each of the second connecting seats 16 at the positions located on both sides of the limiting disk 18.

[0027] A horizontal hydraulic cylinder 21 is fixedly mounted on the side of the brake disc 18 away from the frame 1. The telescopic rod of the hydraulic cylinder 21 passes through the rotating shaft 2 and a connector 22 is fixedly provided at its end. The connector 22 is fixedly connected to the end of the sliding sleeve 13 away from the frame 1. In addition, a hydraulic station 23 for providing power to the hydraulic cylinder 21 is fixedly mounted at the bottom of the frame 1. The hydraulic cylinder 23 is connected to the hydraulic oil pipeline (not shown in the figure) of the hydraulic station 23 through a rotary joint 24.

[0028] In practical applications, the present invention uses a crane or forklift to place the metal sheet roll onto the unloading rack. The extension of the hydraulic cylinder causes the connector 22 to drive the sliding sleeve 13 to slide linearly. During the linear sliding of the sliding sleeve 13, multiple pairs of connecting struts hinged between the first and second connecting seats simultaneously drive multiple support plates to expand outward. Each support plate expands and supports the metal sheet roll, ensuring stable unloading during subsequent operation of the unloading machine.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
