Description

Technical Field

[0001] The utility model relates to the technical field of metal belt cooling, in particular to a cooling mechanism for a metal belt. Background Art

[0002] After hot rolling, in order to achieve rapid cooling of the metal strip to facilitate subsequent processing, it is often necessary to use a cooling structure to cool the metal strip.

[0003] A Chinese patent with patent number CN216557924U discloses a metal strip cooling device, including a clamping component, wherein two clamping components are provided, and the two clamping components clamp the metal strip at the top and bottom of the metal strip respectively; the clamping component includes an anti-scratch sheet, a water tank and a baffle from the inside to the outside; the two anti-scratch sheets are used to clamp the metal strip, and the metal strip passes through the gap between the anti-scratch sheets of the two clamping components; the bottom of the water tank abuts against the anti-scratch sheet, and the water tank is used to cool the metal strip and the anti-scratch sheet; the baffle is used to close the water tank, and a limit assembly is also provided on the side of the baffle, and the limit assembly is used to limit the anti-scratch sheet from sliding out of the clamping component.

[0004] Although the metal strip cooling device described in the above patent can cool the metal strip by passing the metal strip through the gap between the two water tanks, and use the anti-scratch sheet to avoid scratches on the surface of the metal strip during cooling, the above cooling mechanism cannot clean the residue on the surface of the metal strip after hot rolling when in use, which makes it easy for the residue to adhere firmly to the surface of the metal strip after cooling. On the other hand, the above cooling mechanism does not press and straighten the metal strip during the cooling process, and cannot prevent the deformation of the metal strip during the cooling process, resulting in poor final cooling quality of the metal strip.

[0019] Furthermore, an operation panel is connected to an outer side wall of the bracket by bolts, and the operation panel is electrically connected to the motor, the air cooler and the electric telescopic rod.

[0020] By adopting the above technical solution, the operation panel mainly controls the coordinated work of the motor, the air cooler and the electric telescopic rod by controlling the on-off of the circuit.

[0021] (III) Beneficial effects

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] like Figure 1-Figure 3 As shown, the cooling mechanism of the metal belt in this embodiment includes a support platform 5, and a bracket 13 is welded together on both sides of the upper end of the support platform 5. Two cleaning frames 2 are installed on one side wall of the bracket 13 in a symmetrical manner. A cleaning roller 3 is installed on each cleaning frame 2, and a flexible brush strip 4 is installed on the outer side of the cleaning roller 3. A motor 6 is installed on the roller shaft of the cleaning frame 2 opposite to the cleaning roller 3 through bolts. The motor 6 mainly provides power for the rotation of the cleaning roller 3, so that the flexible brush strip 4 can be used to clean the residue on the surface of the metal belt while the cleaning roller 3 rotates. An electric telescopic rod 14 is installed in the middle of the upper end of the support platform 5 and the middle of the top end of the bracket 13. The telescopic part of the electric telescopic rod 14 is connected to the jet hood 9, and a mounting groove 10 is reserved on the clamping surface of the jet hood 9. A clamping roller 12 is rotatably installed in the groove 10, and the electric telescopic rod 14 is mainly used to clamp the clamping roller 12 on the upper and lower sides of the metal belt so as to clamp and straighten the metal belt during the movement and cooling process of the metal belt. A lubricating sleeve 15 is fixed to the outside of the clamping roller 12, and the lubricating sleeve 15 is a graphene sleeve. The lubricating sleeve 15 can effectively reduce the friction molding wear between the surface of the clamping roller 12 and the metal belt. Jet holes 11 are evenly opened on both sides of the installation groove 10 on the clamping wall of the jet hood 9. A cooler 1 is installed in the middle of the top of the bracket 13. The air outlet of the cooler 1 is connected to a three-way pipe 8 for blowing air into the jet hood 9. Under the action of the three-way pipe 8, the cold air blown out by the cooler 1 is smoothly introduced into the jet hood 9, so that the cold air is blown to the surface of the metal belt through the spray hole to achieve cooling of the metal belt.

[0031] like Figure 1-Figure 3 As shown, in this embodiment, the cleaning frame 2 is welded to the bracket 13, and the cleaning roller 3 is rotatably connected to the cleaning frame 2, which can ensure the convenient rotation of the cleaning roller 3 relative to the cleaning frame 2. The motor 6 is connected to the cleaning roller 3 through a coupling, and the flexible brush strip 4 is bonded to the cleaning roller 3. The telescopic part of the electric telescopic rod 14 is bolted to the jet hood 9. The jet hood 9 has a hollow structure. The three-way pipe 8 is connected to the jet hood 9 through a telescopic hose. The bottom end of the clamping roller 12 extends into the installation groove 10, and the lubricating sleeve 15 is bonded to the clamping roller 12.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, an operation panel 7 is connected to an outer side wall of the bracket 13 by bolts, and the operation panel 7 is electrically connected to the motor 6, the air cooler 1 and the electric telescopic rod 14. The operation panel 7 mainly controls the coordinated work of the motor 6, the air cooler 1 and the electric telescopic rod 14 by controlling the on and off of the circuit.

[0033] The specific implementation process of this embodiment is as follows: during cooling, the metal strip in the continuous conveying process after hot rolling is first passed through two cleaning rollers 3 and the jet hood 9, and the clamping roller 12 is clamped on the metal strip under the action of the electric telescopic rod 14, and then the motor 6 and the cold air blower 1 are started. After the motor 6 is started, the cleaning roller 3 will be used to clean the residue on the surface of the metal strip to avoid the strong adhesion of the residue on the metal strip after cooling. When the cold air blower 1 is started, cold air will be blown into the jet hood 9 through the three-way pipe 8, so as to cool the metal strip after the cold air is sprayed onto the metal strip. Under the above cooling method, not only the existence of residue on the surface of the metal strip after cooling is avoided, but also the deformation of the metal strip after cooling is prevented, thereby improving the final cooling quality of the metal strip.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
