Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-5As shown, this utility model is a hot-rolled strip steel rolling device with a lubrication mechanism. It includes a frame 1 with a receiving tray 11, which is fixedly connected to the lower inner side of the frame 1 to receive overflowing lubricating fluid for easy recycling and to avoid waste. Cylindrical support seats 12 are fixedly connected to both sides of the upper end of the frame 1. Rollers 13 are rotatably mounted on the sides of the cylindrical support seats 12. One end of the roller 13 is connected to a drive motor 14 via a shaft. The drive motor 14 rotates the roller 13, aligning it with the mill frame. This allows for relative rotation adjustment with other rollers, facilitating the rolling of hot-rolled steel strip. An adjusting disc 15 is rotatably sleeved on the shaft end of the roller 13. A support cylinder 16 is fixedly connected to the outer side of the adjusting disc 15. Thus, the adjusting disc 15 and the roller 13... Roller 13 does not rotate synchronously. During the rotation of the driving roller 13, the adjusting disc 15 can be rotated independently to adjust the angle, avoiding interference. The support cylinder 16 is rotatably sleeved on the outer surface of the cylindrical support base 12. The two support cylinders 16 are respectively connected to the cylindrical support bases 12 on both sides. Combined with the cross plate 2 fixedly connected between the adjusting discs 15, the lateral position can be fixed and will not move, ensuring structural stability. One end of the support cylinder 16 is threaded with a positioning screw 17. The support cylinder 16 and the positioning screw 17 are installed through the adjusting disc 15, thereby connecting to the cylindrical support base 12. In this way, the support cylinder 16 is sleeved on the cylindrical support base 12, which can support and position the adjusting disc 15. Combined with the positioning screw 17 being tightened onto the cylindrical support base 12, it can directly... The locking and positioning mechanism ensures that the inner wall of the support cylinder 16 fits against the surface of the cylindrical support base 12, thereby increasing frictional resistance and locking the support cylinder 16 in place. This ensures the stability of the adjusting disc 15 and allows for a stable connection to the horizontal plate 2, preventing the horizontal plate 2 from changing its angular position relative to the roll 13. When adjustment is needed, the support cylinder 16 can be rotated on the surface of the cylindrical support base 12, causing the adjusting disc 15 to rotate and the horizontal plate 2 to be rotated to different angular positions on the roll 13. Then, the positioning screw 17 is tightened to reposition the plate, facilitating adjustment and use. Lubrication can be applied from above, sides, or below, offering high adaptability. This prevents interference with other equipment or steel strips, ensuring safety and stability. The positioning screw 17 is installed on the cylindrical support base 12 through threaded holes. A horizontal plate 2 is fixedly connected to the outside of the column support 12 and the side of the adjusting plate 15. A conduit 21 is fixedly connected to the middle of the horizontal plate 2. A branch pipe 22 is fixedly connected to the lower end of the conduit 21. A nozzle 23 is fixedly installed on the lower surface of the branch pipe 22. The nozzle 23 installed below the branch pipe 22 allows lubricant to be introduced through the conduit 21 and sprayed directly from the nozzle 23 onto the surface of the roll 13, providing lubrication and cooling, facilitating protection, and ensuring the safety of rolling production. A coating component 24 is sleeved on the surface of the nozzle 23. The coating component 24 includes a square frame 25 and a coating sponge block 26 fixed inside the square frame 25. The upper end of the coating sponge block 26 is fixedly connected inside the square frame 25, while the lower end extends outward to avoid interference during coating.The application sponge block 26 is fitted onto the outer surface of the nozzle 23. After installing the application assembly 24, its height can be adjusted to switch lubrication modes. When fitted above the nozzle 23, it does not affect the nozzle 23's port position, allowing direct lubrication. When adjusted downwards, it fits at the nozzle 23's port position, spraying lubricant into the interior of the application sponge block 26, which then adheres to the surface of the roller 13 for even lubrication, resulting in a more uniform application and ease of use. In practical use, the support cylinder 16 can be fixed to position the adjusting plate 15, thereby stabilizing the position of the horizontal plate 2, which also fixes the angle of the branch pipe 22 and the nozzle 23 toward the roller. Lubricant can be sprayed for lubrication and protection. When adjustment is needed, the positioning screw 17 can be loosened, and the support cylinder 16 can rotate on the cylindrical support base 12, which can change the angle of the adjusting plate 15 and the horizontal plate 2. This changes the spraying position of the nozzle 23. The adjusting plate 15 and the roller 13 rotate coaxially, which can ensure that the nozzle 23 is facing the roller and avoid misalignment. This makes the nozzle highly adaptable. Furthermore, both ends of the square frame 25 are rotatably mounted with adjusting screws 27. The adjusting screws 27 are threaded onto both ends of the branch pipe 22. The height of the square frame 25 can be adjusted by adjusting the threads of the adjusting screws 27, which facilitates switching between uses. Furthermore, the inside of the application sponge block 26 is provided with a socket 28, and the two sides of the socket 28 are provided with a partition slit 29. Furthermore, the inner diameter of the socket 28 is no greater than the outer diameter of the nozzle 23. The socket 28 is fitted onto the outer surface of the nozzle 23. By setting the socket 28 and the partition 28, the nozzle can be fitted for sliding adjustment. The partition 28 can be expanded to increase the inner diameter to avoid interference. After being adjusted to the position below the nozzle, the outlet can be narrowed, thereby ensuring that the lubricant is sprayed into the application sponge block 26, which is convenient for control and precise and efficient. During specific adjustments, the adjusting screw 27 can be rotated to push the square frame 25 downwards, and the coating sponge block 26 fitted on the upper end of the nozzle 23 can move downwards to cover the outlet position of the nozzle 23. The coating sponge block 26 can be pressed down to contact the surface of the roller 13. In this way, the lubricant sprayed from the nozzle 23 first wets the coating sponge block 26, and when the roller 13 rotates, it can be directly applied to the surface for lubrication, reducing splashing, making it safe and environmentally friendly, and facilitating switching between uses. Furthermore, a feeding assembly 3 is provided on the outside of the frame 1. The feeding assembly 3 includes a material box 31, a pump head 32, and a hose 33 connected to the outlet of the pump head 32. The feeding assembly 3 is fixedly connected to the outside of the frame 1. Furthermore, the pump head 32 is fixedly installed at the upper end of the material box 31, and the end of the hose 33 is fixedly connected to the inside of the conduit 21. The inlet of the pump head 32 is connected to the material extraction pipe, which is inserted into the material box 31 for positioning. Then, by installing the pump head 32 and the hose 33 through the material box 31, lubricant can be drawn and passed into the hose 33, thereby supplying it to the inside of the conduit 21, which facilitates spraying lubrication and is convenient for operation. Furthermore, the upper end of the material tank 31 is provided with a feeding pipe 34, which is located on one side of the pump head 32, making it convenient to add lubricating fluid and replenish it. In practical use, after the lubricant is prepared, it is added into the material box 31 through the feeding pipe 34 for storage. After the pump head 32 is powered on, the lubricant is drawn through the extraction pipe and introduced into the hose 33, which can be directly introduced into the conduit 21 and the branch pipe 22. Then it is sprayed out from the multiple nozzles 23 below, which can be directly sprayed onto the surface of the roll 13 for lubrication and cooling, which is beneficial for safety protection. In summary, this invention, through the combination of an adjustable nozzle and a coating component, enables flexible switching between spraying and coating lubrication methods, effectively avoiding interference issues and improving lubrication uniformity and equipment adaptability.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
