[0002] In the production process of a cold rolling mill, the feeding device is one of the key links to ensure the smooth progress of the production process. Traditionally, conveyor belts are mostly used as the main way to transport materials in the feeding device of a cold rolling mill. However, with the continuous development of industrial technology and the improvement of product quality requirements, the inherent limitations of the traditional conveyor belt feeding method have gradually emerged.

[0003] In the prior art, the authorized announcement number is: CN214211752U, and the name is a feeding and conveying device for a cold rolling mill. This patent includes a base, a feeding mechanism, and a discharging component. The feeding mechanism is fixed on the base, and the discharging component is located on one side of the feeding mechanism and is fixedly arranged above the base to ensure that the discharging end of the feeding mechanism corresponds to the feeding end of the discharging component. This device automatically feeds cold rolling steel bars through the feeding mechanism, replacing the traditional manual feeding method, significantly improving the production efficiency. At the same time, the discharging component can achieve the equal - amount conveying of cold rolling steel bars to ensure the orderly progress of the feeding process. This device has a simple structure, a high degree of automation, does not require manual operation, the feeding is equal - amount and is convenient for subsequent processing, and has high practicability and efficiency.

[0004] However, when this patent transports materials through a conveyor belt, there are problems of instability and low precision.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] Example 1

[0027] As Figures 1 to 5 shown, this embodiment proposes a loading device for a cold rolling mill, including a loading cart base 1. Two symmetrically arranged connecting plates 2 are fixedly connected to the bottom of the loading cart base 1. Two symmetrically arranged loading cart guide columns 3 are fixedly connected to the bottom of the loading cart base 1. Two symmetrically arranged through grooves 22 are respectively opened in the two connecting plates 2. Guide wheel shafts 8 are rotatably installed in the two through grooves 22. Driven guide wheels 23 and driving guide wheels 9 are respectively fixedly sleeved on the outer parts of the two guide wheel shafts 8. Through the settings of the hopper main body 7 and the driving guide wheel 9 and other structures, the driving guide wheel 9 is arranged on the guide rail, and it is driven by the hydraulic motor 14 to rotate so as to achieve the effect of movement. The overall movement is more flexible and precise. Through the setting of the grooves on the hopper main body 7, the steel coil can be placed on it to form a certain effect, so that the materials to be transported are placed more stably, and the overall transportation effect is improved.

[0028] As Figures 1 to 5 shown, mounting plates 11 are fixedly connected to one side of the two connecting plates 2 respectively. Hydraulic motors 14 are installed on one side of the two mounting plates 11 respectively. The output end of the hydraulic motor 14 is fixedly connected with a coaxial rotating rod 13 through a coupling. One end of the rotating rod 13 is fixedly connected with a driving gear 12.

[0029] As Figures 1 to 5 shown, guide rail gears 10 are fixedly connected to one side of the two guide wheel shafts 8 located on the driving guide wheel 9 respectively. The two guide rail gears 10 are respectively meshed with the two driving gears 12.

[0030] As Figures 1 to 5 shown, a lifting hydraulic cylinder 4 is installed inside the loading cart base 1. The output end of the lifting hydraulic cylinder 4 extends out of the inside of the loading cart base 1. Four telescopic rods 5 are fixedly connected to the top of the loading cart base 1. Four hopper limit columns 6 are fixedly connected to the top of the loading cart base 1.

[0031] As Figures 1 to 5 shown, the four telescopic rods 5 and the top of the output end of the lifting hydraulic cylinder 4 are jointly fixedly connected with a hopper main body 7. The four hopper limit columns 6 are slidably connected inside the hopper main body 7. The hopper main body 7 is in the shape of a groove.

[0032] In this embodiment, when in use, the driven guide wheel 23 and the driving guide wheel 9 need to be arranged on the groove of the guide rail to provide the ability to move. The loading cart guide post 3 can play a certain limiting role to prevent the guide wheel from derailing during the movement. During the movement, the hydraulic motor 14 is started to drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it drives the driving gear 12 to rotate. The driving gear 12 drives the rotation of two of the guide wheel shafts 8 by meshing with the guide rail gear 10. The two guide wheel shafts 8 drive the two driving guide wheels 9 to rotate, thereby realizing the movement of the entire device. Through the setting of the guide rail and the guide wheel, the movement of transportation can be realized more accurately, with fewer restrictions compared to the conveyor belt. After moving to the designated position, the setting of the lifting hydraulic cylinder 4 can push the hopper body 7 to change its longitudinal position. During the lifting process, the material falls onto the hopper body 7, and then it is transported and the steel coil is sleeved on the reel by moving. Since the horizontal and vertical positions can be controlled arbitrarily, more flexible docking for loading can be achieved.

[0033] Embodiment 2

[0034] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that an auxiliary component 15 is provided on the hopper body 7. The auxiliary component 15 includes a protective shell 16. The protective shell 16 is fixedly connected to one side of the hopper body 7. A driving motor 18 is installed on one side of the protective shell 16. Through the settings of structures such as the clamping plates 19 and the pushing plate 21, in the case of an overly long steel coil, in order to avoid unstable placement, the two clamping plates 19 can be used to stably clamp and fix the steel coil. After reaching the designated position, the steel coil is released. Through the setting of the pushing plate 21, it can assist in loading, achieving a better fixing effect.

[0035] As Figures 1 to 5 shown, the output end of the driving motor 18 is fixedly connected with a coaxial bidirectional screw rod 17 through a coupling. The bidirectional screw rod 17 is rotatably installed inside the protective shell 16. Opposite threads are provided on the outside of the bidirectional screw rod 17. The outside of the two threads is equipped with clamping plates 19 through ball nuts. A limiting groove is opened at the top of the protective shell 16, and the two clamping plates 19 are both slidably connected inside the limiting groove.

[0036] As Figures 1 to 5 shown, an electric control cylinder 20 is installed on the other side of the hopper body 7. A pushing plate 21 is fixedly connected to the telescopic end of the electric control cylinder 20.

[0037] In this embodiment, when the steel coil is placed on the hopper main body 7, since the length of the steel coil is not necessarily fixed, when encountering a longer steel coil, it is likely to tip over when placed on the hopper main body 7. Therefore, by starting the driving motor 18, the bidirectional screw 17 is rotated. Driven by its rotation, the two clamping plates 19 move towards each other to fix the steel coil. After fixation, the steel coil is transported. After the steel coil is sleeved on the drum, the driving motor 18 rotates in reverse. At this time, the clamping plates 19 release the steel coil, and then the push plate 21 is driven to move by the telescopic movement of the electric control cylinder 20 to assist the feeding of the longer steel coil.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
