[0002] Steel is a material with a specific shape, size, and properties, made from steel ingots, billets, etc., through pressure processing. Most steel processing involves pressure processing, causing the steel to undergo plastic deformation and thus become the shape required by the producer. Depending on the processing temperature, it can be divided into cold working and hot working. Cold rolling is a type of cold working. When processing steel, no heating treatment is required. Cold rolling is carried out at room temperature. Cold rolling requires the use of a cold rolling mill, and a protective device is needed at the discharge port of the cold rolling mill to support the material.

Although the above-mentioned prior art achieves protection when unloading the spiral blades, in actual use, the lateral movement and lifting action of the prior art are controlled by independent motors, resulting in a complex structure of the entire drive system, high manufacturing cost, and the need to configure multiple sets of control circuits, which increases the equipment failure rate and maintenance difficulty. In view of this, we propose a switchable cold rolling mill discharge protection device to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a switchable cold rolling mill discharge protection device, including a movable base 1, a fixed plate 2 fixedly connected to the upper surface of the base 1, a vertical plate 3 slidably connected inside the fixed plate 2 to provide installation space for components, a bearing hopper 4 for carrying materials on both sides of the vertical plate 3, a sliding groove 5 opened inside the vertical plate 3, two first threaded rods 6 for transmission rotatably connected inside the sliding groove 5, two connecting plates 7 for support slidably connected inside the sliding groove 5, the connecting plates 7 are threadedly sleeved on the outside of the first threaded rods 6, the connecting plates 7 and the bearing hoppers 4 are fixedly connected, a first cavity 10 opened inside the vertical plate 3, a transmission component is arranged inside the first cavity 10, a second cavity 11 opened inside the vertical plate 3, a transverse component is arranged inside the second cavity 11.

[0019] The transmission assembly includes two first rotating rods 12 for transmission. Both first rotating rods 12 are rotatably connected inside the first cavity 10. The lower ends of both first rotating rods 12 rotatably penetrate into the interior of the sliding groove 5. The two first rotating rods 12 are respectively fixedly connected to two first threaded rods 6.

[0020] Both first rotating rods 12 are fixedly fitted with transmission gears 13 for transmission. The two transmission gears 13 are meshed and connected. A motor 14 for providing power is fixedly connected to the upper surface of the vertical plate 3. The output shaft of the motor 14 rotates through the interior of the vertical plate 3 and is fixedly connected to the front first rotating rod 12 through a coupling. The motor 14 can be started by an external controller to drive the rotation of the front first rotating rod 12. At this time, the two first rotating rods 12 can be driven to rotate in opposite directions through the transmission of the transmission gears 13. The rotation of the two first rotating rods 12 can drive the two first threaded rods 6 to rotate in opposite directions, so that when the front bearing bucket 4 descends, the rear bearing bucket 4 will rise, thereby achieving the effect of unloading material from the front bearing bucket 4 and continuing to carry material from the rear bearing bucket 4.

[0021] The fixed plate 2 has a second threaded rod 9 for transmission fixedly connected inside, and the vertical plate 3 is movably sleeved on the outside of the second threaded rod 9.

[0022] The lateral movement assembly includes a second rotating rod 15 for rotation. The second rotating rod 15 is rotatably connected to the top wall of the second cavity 11. The upper end of the second rotating rod 15 rotatably penetrates into the interior of the sliding groove 5 and is fixedly connected to the front first threaded rod 6. The lower end of the second rotating rod 15 is fixedly connected to a first bevel gear 16 for transmission. The rotation of the first threaded rod 6 drives the rotation of the second rotating rod 15, which in turn drives the first bevel gear 16 to rotate. A threaded sleeve 17 is rotatably connected inside the second cavity 11. The threaded sleeve 17 is threadedly sleeved on the outside of the second threaded rod 9. A transmission mechanism is fixedly sleeved on the outside of the threaded sleeve 17. The second bevel gear 18 is connected to the first bevel gear 16. The rotation of the first bevel gear 16 drives the rotation of the second bevel gear 18, which in turn drives the rotation of the threaded sleeve 17. Since the threaded sleeve 17 is rotatably connected inside the second cavity 11 and the thread is sleeved outside the second threaded rod 9, the rotation of the threaded sleeve 17 will cause the vertical plate 3 to slide inside the fixed plate 2. This will result in the rear bearing bucket 4 rising and the front bearing bucket 4 falling, while also causing a lateral displacement, so that the rear bearing bucket 4 can be aligned with the discharge port of the cold rolling mill.

[0023] In the above embodiment, in actual use, it is only necessary to align the middle of the device with the unloading end of the cold rolling mill. At this time, the high-positioned support bucket 4 will also be located in the middle of the base 1, that is, aligned with the unloading end of the cold rolling mill. Subsequently, when the low-positioned support bucket 4 rises, it will also move laterally to the middle of the base 1, so that the rising support bucket 4 will automatically align with the unloading end of the cold rolling mill without any additional operation.

[0024] The outer side of the carrying hopper 4 is provided with a side plate 19 to prevent material from falling. A rotating shaft 20 is provided between the side plate 19 and the carrying hopper 4. The side plate 19 and the carrying hopper 4 are rotatably connected through the rotating shaft 20. A U-shaped frame 23 is fixedly connected to the lower surface of the carrying hopper 4. A horizontal plate 24 is slidably connected inside the U-shaped frame 23. The end of the horizontal plate 24 abuts against the lower end of the side plate 19. Connecting blocks 25 are fixedly connected to both sides of the horizontal plate 24.

[0025] A guide rod 26 for limiting the movement trajectory of the connecting block 25 is fixedly connected to the surface of the C-shaped frame 23. The connecting block 25 is slidably sleeved on the outside of the guide rod 26. A reset spring 8 for resetting the horizontal plate 24 is fixedly connected between the C-shaped frame 23 and the connecting block 25. The reset spring 8 is movably sleeved on the outside of the guide rod 26. With the setting of the horizontal plate 24, when the horizontal plate 24 abuts against the bottom of the side plate 19, the side plate 19 cannot rotate, which can effectively limit the spiral blades located on the upper side of the bearing bucket 4.

[0026] Two vertical grooves 21 are provided on both sides of the vertical plate 3. A connecting groove 22 is provided at the bottom of the vertical groove 21. Two adjacent vertical grooves 21 are connected to each other through the connecting groove 22. The horizontal plate 24 extends into the interior of the vertical groove 21. When the carrying bucket 4 is at a high position, the end of the horizontal plate 24 inside the vertical groove 21 will abut against the inner wall of the vertical groove 21. At this time, the side plate 19 cannot rotate. When the carrying bucket 4 is at a low position, the horizontal plate 24 will be located inside the connecting groove 22. When the material is unloaded, the spiral blades come into contact with the side plate 19 and force the side plate 19 to flip. At this time, the side plate 19 will force the horizontal plate 24 to slide inside the U-shaped frame 23, and the return spring 8 will generate elastic deformation so that the horizontal plate 24 can reset the side plate 19 again.

[0027] In the above embodiments, a pulley can also be provided at one end of the horizontal plate 24 located inside the vertical groove 21, thereby reducing the friction between the horizontal plate 24 and the vertical groove 21 and ensuring the smoothness of the horizontal plate 24 when sliding.

[0028] Working principle: When in use, the switchable cold rolling mill discharge protection device is moved to the discharge port of the cold rolling mill via the base 1, that is, the front bearing hopper 4 located at the higher position is aligned with the discharge port of the cold rolling mill. Subsequently, the front bearing hopper 4 located at the higher position will carry materials. When the material is full and needs to be unloaded, the motor 14 is started by the external controller, which drives the rotation of the front first rotating rod 12. At this time, the transmission gear 13 drives the two first rotating rods 12 to rotate in opposite directions. The rotation of the two first rotating rods 12 drives the two first threaded rods 6 to rotate in opposite directions, so that when the front bearing hopper 4 descends, the rear bearing hopper 4 will rise, which facilitates the unloading of the front bearing hopper 4 and the continued carrying of materials by the rear bearing hopper 4.

[0029] In addition, the rotation of the first threaded rod 6 can drive the rotation of the second rotating rod 15, which in turn drives the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 can drive the rotation of the second bevel gear 18, which in turn drives the rotation of the threaded sleeve 17. Since the threaded sleeve 17 is rotatably connected inside the second cavity 11 and the threaded sleeve is fitted outside the second threaded rod 9, the rotation of the threaded sleeve 17 will drive the vertical plate 3 to slide inside the fixed plate 2. This will ultimately achieve the simultaneous lateral displacement of the rear bearing bucket 4 as it rises and the front bearing bucket 4 descends, so that the rear bearing bucket 4 can be aligned with the discharge port of the cold rolling mill.

[0030] In addition, when the front hopper 4 descends to facilitate unloading, it also causes the horizontal plate 24 to slide inside the vertical groove 21, that is, it causes the horizontal plate 24 to slide from the vertical groove 21 into the interior of the connecting groove 22. When the lower hopper 4 unloads, it forces the side plate 19 to tilt, that is, the side plate 19 forces the horizontal plate 24 to slide inside the U-shaped frame 23, and the return spring 8 will produce elastic deformation so that the subsequent horizontal plate 24 can make the side plate 19 return to its original position. Since the horizontal plate 24 of the rear hopper 4 located at the higher position is inside the vertical groove 21, the side plate 19 of the rear hopper 4 will not flip, thus ensuring the restriction of the spiral blade.

[0031] 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.
