Description

Technical Field

[0001] This utility model is specifically a cooling device for steel strip production, belonging to the field of steel strip production technology. Background Technology

[0002] Steel strip is a type of steel with large output, wide application, and many varieties. It is classified into hot-rolled steel strip and cold-rolled steel strip according to processing method, thin steel strip and thick steel strip according to thickness, wide steel strip and narrow steel strip according to width, narrow steel strip is further divided into directly rolled narrow steel strip and narrow steel strip slid from wide steel strip, and steel strip with original rolled surface and coated surface according to surface condition. During the production process of steel strip, if the temperature of the produced steel strip is too high, a cooling device needs to be set up for cooling. Chinese Patent Publication No. CN214950115U discloses a cooling device for steel strip production, including a conveyor belt. A cooling box is fixedly connected to the top of the conveyor belt, and a motor is fixedly connected to the left side of the cooling box. A first helical gear is fixedly connected to the output end of the motor. This invention involves placing the steel strip on the surface of the conveyor belt, starting the motor after placement, and having the output end of the motor drive the first helical gear to rotate. The first helical gear drives the second helical gear to rotate, and the second helical gear drives the rotating rod to rotate. The rotating rod drives the moving block to move to the right. When the moving block reaches the end, the motor rotates in the opposite direction, causing the rotating rod to drive the moving block to move back, so that the cooling fan cools the steel strip, thus achieving the advantage of high-efficiency cooling. In the existing technology, when cooling steel strip, a cold air blower is used to blow cold air onto the steel strip to lower its temperature. Due to the lack of a more efficient heat transfer path, single air cooling cannot remove the heat inside the steel strip in time. The heat exchange efficiency between the cold air and the surface of the steel strip is low, resulting in a slow cooling rate of the steel strip. This still results in poor cooling effect, long cooling time, and reduced cooling efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cooling device for steel strip production in order to solve the above-mentioned problems. This device addresses the issue that the heat exchange efficiency between the cold air and the surface of the steel strip is too low in the prior art, resulting in a slow cooling rate of the steel strip, which in turn leads to poor cooling effect, long cooling time, and reduced cooling efficiency.

[0004] This utility model is achieved through the following technical solution: a cooling device for steel strip production, including a base plate, a rotating frame symmetrically fixed on the top of the base plate, a guide roller rotating between the two sides inside the rotating frame, a mounting frame fixed in the middle of the top of the base plate, a cooling mechanism connected to the inner side of the mounting frame, and a swing mechanism connected to the outer side of the mounting frame, the cooling mechanism being connected to the inside of the mounting frame through the swing mechanism.

[0005] Preferably, the cooling mechanism includes a mounting frame connected to the inner side of the mounting bracket via the swing mechanism. A mounting plate is fixed to the top between the two sides of the inner cavity of the mounting frame. Cooling fans are uniformly fixed to the bottom of the mounting plate. Fixing plates are symmetrically fixed to the bottom of the mounting frame. A diversion box is fixed to the bottom between the opposite sides of the two fixing plates. Atomizing nozzles are uniformly fixed to the bottom of the diversion box. A connecting pipe is fixed to the middle of one side of the diversion box. A pump is fixed to the top edge of the mounting bracket. A water outlet pipe is fixed to the outlet end of the pump.

[0006] Preferably, the cooling fan is located at the top of the atomizing nozzle, so that the cooling fan can blow the water mist sprayed from the atomizing nozzle toward the steel strip.

[0007] Preferably, the water outlet pipe is a flexible hose to prevent the hose from affecting the rotation when the mounting frame is deflected, and the outlet end of the water outlet pipe is fixed to the outside of the connecting pipe, so that the pump can send the external water source into the diversion box through the water outlet pipe.

[0008] Preferably, the swing mechanism includes a dual-axis motor fixed to the top center of the mounting frame, a turntable fixed to the end of the output shaft of the dual-axis motor, a connecting shaft fixed to one side of the turntable, connecting plates fixed at the four corners of the top of the mounting frame, sliding rods symmetrically fixed to the top of the opposite sides of the two connecting plates, an L-shaped rod sliding on the outside of the sliding rod, and a U-shaped rod fixed to one end of the L-shaped rod.

[0009] Preferably, the connecting shaft is located inside the spiral rod, and the deflection circumference diameter of the connecting shaft is smaller than the inner length of the spiral rod, so as to avoid motion interference between the connecting shaft and the spiral rod when the connecting shaft deflects.

[0010] Preferably, the top of both sides of the mounting frame is provided with a rotating shaft, one end of which is fixed with a gear. The rotating shaft is fixed to the middle of both sides of the mounting frame, and when the rotating shaft rotates, it causes the mounting frame to deflect.

[0011] Preferably, a rack is fixed to the bottom end of the L-shaped rod, and the bottom of the rack meshes with the outer wall of the gear. When the rack moves, it facilitates the rotation of the gear, thereby driving the shaft to rotate.

[0012] This utility model provides a cooling device for steel strip production, which has the following beneficial effects: This application utilizes a cooling mechanism that draws external water from a pump, directs it into the outlet pipe, and then through a connecting pipe into the distribution box. Finally, the water is sprayed out through atomizing nozzles, creating a water mist. Simultaneously, a cooling fan is activated to generate airflow, which blows the sprayed water mist onto the steel plate, cooling it down. This combination of gas cooling and water mist cooling further enhances the cooling effect, reduces cooling time, and improves cooling efficiency.

[0013] This application utilizes a swing mechanism. By activating a dual-axis motor, the turntable rotates, causing the connecting shaft to move in a circular motion. This motion compresses the inner wall of the return rod, causing the return rod to move the L-shaped rod back and forth. This, in turn, causes the rack to move back and forth, resulting in the gears reciprocating and deflecting. This, in turn, causes the rotating shaft to reciprocate and deflect, which in turn causes the mounting frame to reciprocate and deflect, and the cooling mechanism to reciprocate and deflect. This increases the cooling range, facilitates the back-and-forth cooling of the steel strip, further improves the cooling effect, and enhances the practicality of the device.

At the same time, the cooling fan 503 is started to generate gas flow, which blows the sprayed water mist towards the steel plate, so that the water mist cools the steel plate, thereby combining gas cooling and water mist cooling to further improve the cooling effect, reduce the cooling time, and improve the cooling efficiency. Example

[0019] Please refer to it again. Figure 4The swing mechanism 6 includes a dual-axis motor 601 fixed to the middle of the top of the mounting frame 4. A turntable 602 is fixed to the end of the output shaft of the dual-axis motor 601. A connecting shaft 603 is fixed to one side of the turntable 602. Connecting plates 604 are fixed at the four corners of the top of the mounting frame 4. Slide rods 605 are symmetrically fixed to the top of the opposite sides of the two connecting plates 604. An L-shaped rod 606 slides on the outside of the slide rod 605. A return rod 607 is fixed to one end of the L-shaped rod 606. A rack 608 is fixed to the bottom end of the L-shaped rod 606. A rotating shaft 609 rotates through the top of both sides of the mounting frame 4. A gear 610 is fixed to one end of the rotating shaft 609. The connecting shaft 603 is located inside the return rod 607, and the deflection circumference diameter of the connecting shaft 603 is smaller than that of the rotation rod 607. The inner length of the return rod 607; the rotating shaft 609 is fixed to the middle of both sides of the mounting frame 501; the bottom of the rack 608 meshes with the outer wall of the gear 610; through the setting of the swing mechanism 6, by starting the dual-axis motor 601, the turntable 602 is driven to rotate, causing the connecting shaft 603 to move in a circular motion, which squeezes the inner wall of the return rod 607, thereby causing the return rod 607 to drive the L-shaped rod 606 to move back and forth, which in turn causes the rack 608 to move back and forth, causing the gear 610 to deflect back and forth, driving the rotating shaft 609 to deflect back and forth, thereby causing the mounting frame 501 to deflect back and forth, causing the cooling mechanism 5 to deflect back and forth, increasing the cooling range, facilitating the back and forth cooling of the steel strip, further improving the cooling effect, and enhancing the practicality of the device.

[0020] When using this utility model: Working principle: Connect the electrical components to an external power supply and control switch. Connect the external water source to the pump 508. Start the cooling fan 503, pump 508, and dual-shaft motor 601. The pump 508 draws the external water source and sends it into the outlet pipe 509. The water then enters the distribution box 505 through the connecting pipe 507 and is finally sprayed out through the atomizing nozzle 506, creating a water mist. Simultaneously, the cooling fan 503 is activated, generating airflow that blows the sprayed water mist onto the steel plate, cooling the steel plate and thus cooling the air and water mist. The cooling effect is further enhanced by combining cooling and heat dissipation. The start of the dual-axis motor 601 drives the turntable 602 to rotate, causing the connecting shaft 603 to move in a circular motion. This compresses the inner wall of the return rod 607, causing the return rod 607 to drive the L-shaped rod 606 to move back and forth. This, in turn, causes the rack 608 to move back and forth, causing the gear 610 to deflect back and forth. This drives the rotating shaft 609 to deflect back and forth, causing the mounting frame 501 to deflect back and forth, and the cooling mechanism 5 to deflect back and forth. This increases the cooling range and facilitates the back and forth cooling of the steel strip, further enhancing the cooling effect.
