DETAILED DESCRIPTION

[0022] The utility model will be described in detail below in combination with the drawings and examples.

[0023] Example 1

[0024] This example provides an inlet material guiding assembly, please refer to Figure 1 , mainly used for the orderly introduction and transmission of materials in steel rolling mill, especially suitable for occasions that need to accurately control the position and height of materials. The structure of the assembly and its working principle will be described in detail below:

[0025] The device housing 1 is the main structure of the entire assembly, and a plurality of feeding rollers are installed inside. These feeding rollers are distributed in the order from top to bottom, and are sequentially the upper layer roller 2, the middle layer roller 3 and the lower layer roller 4. The upper layer roller 2 and the middle layer roller 3, and the middle layer roller 3 and the lower layer roller 4 form the upper layer feeding channel 6 and the lower layer feeding channel 7 respectively. The main function of these two channels is to guide the orderly movement of materials inside the assembly. When the material enters the assembly, it first enters the upper layer feeding channel 6 or the lower layer feeding channel 7 through the feeding inlet 8. With the rotation of the feeding roller, the material is gradually transmitted in the channel to the discharging outlet 9, and then leaves the assembly through the discharging outlet 9. During the transmission process, the movement assembly is located inside the device and is not affected by external conditions, so the conveying is more stable and the guidance is more accurate.

[0026] In order to improve the transmission efficiency of the material, conveying belt mechanisms 5 are installed between the adjacent feeding rollers on one side of the bottom of the upper layer feeding channel 6 and the lower layer feeding channel 7. These conveying belt mechanisms 5 play the role of auxiliary guiding and intermediate support during the material transmission process, ensuring that the material can be smoothly transmitted inside the channel and finally discharged from the discharging outlet 9.

[0027] Example 2

[0028] This example is a further embodiment based on example 1, please refer to Figures 1-3 In order to meet the needs of different material heights, the side of the device housing 1 where the discharging outlet 9 is installed is provided with a feeding height adjusting device 10. The device is mainly composed of a flexible guide sleeve 11 and a lifting feeding clamp plate 12. One end of the flexible guide sleeve 11 is connected to the discharging outlet 9 of the device housing 1, and the other end is connected to the lifting feeding clamp plate 12.

[0029] In order to increase the flexibility and stability of the adjustment, the flexible guide jacket 11 and the lifting feeding clamp plate 12 are arranged in two groups in the vertical direction within the height adjustment device 10, and are separated by the intermediate partition plate 13. This structure enables the assembly to simultaneously process two different heights of materials, improving work efficiency. Workers in the field can also set up three or more identical mechanisms to meet the feeding needs of different rolling mills.

[0030] Embodiment 3

[0031] This embodiment is a further implementation based on Embodiment 2, please refer to Figures 1-3 When the height of the material needs to be adjusted, the lifting feeding clamp plate 12 moves in the vertical direction within the height adjustment device 10. For example, the vertical movement can be achieved by adjusting the height adjustment screw 14. The end of the height adjustment screw 14 is connected with the driving motor 16, and the rotation of the driving motor 16 can drive the lifting of the lifting feeding clamp plate 12 on the screw, thereby driving the up and down movement of the lifting feeding clamp plate 12.

[0032] In order to ensure the smooth movement of the lifting feeding clamp plate 12, the inner wall of the height adjustment device 10 and the intermediate partition plate 13 can be connected with the guide rod 15. The main function of the guide rod 15 is to provide stable support and guidance, preventing the lifting feeding clamp plate 12 from shifting or shaking during lifting. The driving motor 16 is fixedly connected with the height adjustment device 10, and is connected with the lifting feeding clamp plate 12 through the height adjustment screw 14. When the driving motor 16 is started, it drives the rotation of the height adjustment screw 14, driving the up and down movement of the lifting feeding clamp plate 12, achieving height adjustment. This structure not only improves the accuracy and stability of the adjustment, but also simplifies the operation process, without the need for manual adjustment.

[0033] Embodiment 4

[0034] This embodiment is a further implementation based on Embodiment 1, please refer to Figure 1 , Figure 3 In order to facilitate the entry and support of the material, the outer wall of the device shell 1 is provided with a feeding support plate 17 corresponding to the position of the feeding port 8. The main function of the support plate is to provide a stable platform for the material to enter the feeding channel smoothly. This structure improves the practicability and stability of the assembly, and also reduces the possibility of jamming or blocking of the material when entering the assembly.

[0035] Embodiment 5

[0036] The embodiment is a steel rolling mill, which can apply the inlet material guiding assembly of any of the above embodiments, for example, connecting the inlet material guiding assembly to one side of the steel rolling mill, fixing the relative positions of the two through the base, adjusting the outlet feeding position of the inlet material guiding assembly according to the feeding requirement, and then putting the steel from the feeding port 8 after starting the inlet material guiding assembly, so that the steel can be guided to the rolling roller on the rolling mill for processing under the conveying of the inlet material guiding assembly, which is also applicable to the steel rolling mill with multiple roller groups.

[0037] The above embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
