Description

Technical Field

[0001] This utility model relates to the field of steel plate feeding technology, specifically an automatic feeding device for a cold rolling mill. Background Technology

[0002] Cold rolling mills are key pieces of equipment in the metal processing and manufacturing industry. They produce high-precision, high-performance thin sheets and strips by rolling metal billets at room temperature. On a cold rolling production line, feeding is the primary and highly repetitive process.

[0003] Currently, many cold rolling mills still rely on manual feeding during processing. Operators need to manually move and pick up stacked steel plates one by one and place them on the conveyor or at the mill inlet. This method has significant drawbacks: First, it greatly increases the labor intensity of workers, especially during batch processing, resulting in low efficiency; second, the inconsistent rhythm of manual operation makes it difficult to achieve efficient and continuous integration with subsequent automated rolling processes, becoming a bottleneck restricting the overall automation level of the production line; third, manual handling of heavy steel plates poses safety hazards and is prone to causing surface scratches due to improper operation, affecting product quality.

[0004] Therefore, developing a feeding device that can automatically and reliably complete the separation and conveying of steel plates is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic feeding device for a cold rolling mill to solve the problems mentioned in the background section.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-4 This utility model provides a technical solution: an automatic feeding device for a cold rolling mill of steel plates, including a roller conveyor 1, a base 2 fixedly installed on the ground on one side of the roller conveyor 1, a pair of C-shaped columns 3 fixedly installed on the base 2, a stop bar 4 fixedly installed on the upper end of the pair of C-shaped columns 3 near the roller conveyor 1, a plurality of baffles 22 fixedly installed between the upper surface of the base 2 and the lower surface of the stop bar 4, a placement plate 6 slidably installed inside the pair of C-shaped columns 3 along the height direction, and a plurality of steel plates are stacked on the top of the placement plate 6, a pair of guide cylinders 7 fixedly installed outside the pair of C-shaped columns 3, a portal frame 8 slidably installed inside the pair of guide cylinders 7 along the height direction, a rotating shaft 9 rotatably installed inside the portal frame 8, a plurality of rubber wheels 10 evenly distributed on the rotating shaft 9, and a drive motor 11 fixedly installed on the portal frame 8 to drive the rotating shaft 9 to rotate. When the placement plate 6 moves upward, the uppermost steel plate can contact the rubber wheels 10, and the rotation of the rubber wheels 10 pushes the steel plate towards the stop bar 4, thereby peeling off the uppermost steel plate.

[0017] As an embodiment of this utility model, a pair of sliders 5 are fixedly provided at both ends of the placement plate 6. The pair of sliders 5 are slidably connected in the grooves of a pair of C-shaped columns 3. A pair of threaded rods 15 are rotatably provided in the grooves of the pair of C-shaped columns 3. The pair of threaded rods 15 are threadedly connected to the pair of sliders 5. The placement plate 6 can be moved up and down by rotating the pair of threaded rods 15.

[0018] As an embodiment of this utility model, the bottom of a pair of threaded rods 15 passes through the base 2 and is fixedly provided with a bevel gear 16. A double-headed motor 17 is fixedly provided below the base 2. A rotating shaft 18 is fixedly provided at each of the two power output ends of the double-headed motor 17. A bevel gear 19 that meshes with the bevel gear 16 is fixedly provided at the end of the rotating shaft 18. The double-headed motor 17 drives the pair of threaded rods 15 to rotate simultaneously. The threads of the pair of threaded rods 15 have opposite directions to ensure that the pair of sliders 5 move up or down simultaneously.

[0019] As an embodiment of this utility model, a fixing block 12 is fixedly installed on the outside of the guide cylinder 7, and a fixing block 24 is fixedly installed at the bottom of the portal frame 8. A spring 13 is installed between the fixing block 12 and the fixing block 24. The spring 13 can push the portal frame 8 to move downward, so that the rubber wheel 10 can be pressed tightly on the steel plate, thereby increasing the friction on the steel plate.

[0020] As an embodiment of this utility model, a sloping plate 20 is fixedly provided on the side of the stop bar 4 near the roller conveyor 1. The sloping plate 20 extends above the roller conveyor 1. When the steel plate is peeled off by the rubber wheel 10, it will slide onto the sloping plate 20. The steel plate can slide on the sloping plate 20, so that the steel plate slides onto the roller conveyor 1.

[0021] As an embodiment of this utility model, a stop block 21 is fixedly provided on the side of the roller conveyor 1 away from the inclined plate 20. When the steel plate slides down from the inclined plate 20, it will generate inertia. The stop block 21 blocks the steel plate so that the steel plate can stay on the roller conveyor 1.

[0022] The working principle and usage process of this utility model are as follows: In use, a forklift moves multiple stacked steel plates onto the placement plate 6. Starting the dual-head motor 17 moves the placement plate 6 upwards, ensuring the top steel plate is above the upper surface of the stop bar 4, while preventing the second layer of steel plates from exceeding the stop bar 4. At this point, the top steel plate can contact the rubber wheel 10. Driven by the spring 13, the rubber wheel 10 presses firmly against the top steel plate. Starting the drive motor 11 rotates the rubber wheel 10, which, under its own weight, peels off the top steel plate and transports it to the inclined plate 20. The second layer of steel plates is blocked by the stop bar 4 and will not move with the top steel plate. Once the steel plates are on the inclined plate 20, they will move along the inclined plate under their own weight. Its inclined surface slides and eventually falls onto the roller conveyor 1. The stop block 21 can block the steel plate and keep it on the roller conveyor 1. The roller conveyor 1 then transports the steel plate to the cold rolling mill for processing. When feeding the next steel plate, the double-headed motor 17 controls the placement plate 6 to move upward. The upward movement distance is equal to the thickness of a single steel plate, so that the current topmost steel plate is higher than the stop bar 4, and the next steel plate can be prepared for feeding. The double-headed motor 17 is a servo motor connected to a servo system. The rotation number of the double-headed motor 17 is precisely controlled by an external controller, thereby precisely controlling the height of the placement plate 6. The servo system and servo motor adopt existing conventional technology, and the specific details will not be elaborated here.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
