Description

Technical Field

[0001] This utility model relates to the technical field of tinplate production, and in particular to a six-stand continuous rolling mill for tinplate production. Background Technology

[0002] Tinplate refers to steel sheets with a thin layer of metallic tin plated on their surface. Tinplate is made by rolling low-carbon steel into sheets approximately two millimeters thick, followed by pickling, cold rolling, electrolytic cleaning and annealing, leveling, edge trimming, cleaning, electroplating, remelting, passivation, oiling, and finally cutting into finished tinplate sheets. The tin used in tinplate plating is high-purity tin. The tin layer can also be applied using hot-dip plating, which results in a thicker tin layer, requires a larger amount of tin, and does not require purification after plating. Continuous rolling of tinplate is a technology that strengthens and improves the corrosion resistance of steel through continuous rolling. Its specific principle is to utilize the high temperature and pressure generated during continuous rolling to rearrange the steel's grains, thereby enhancing the steel's strength and stability. Furthermore, due to the high temperature and pressure during continuous rolling, continuous rolling of tinplate can also effectively improve the corrosion resistance of steel.

[0003] The existing Chinese utility model patent with application number CN202022359761.X relates to a four-rolling mill equipment, including the main body of the equipment, support, single rolling mechanism, rolls, rotating shaft, lifting channel and top frame, etc. It can be used for hot rolling of aluminum bars of various thicknesses. The rotation of the rolls can be driven by a motor. The four-rolling mill equipment is simple to operate and easy to adjust.

[0004] However, in actual use, the conveying distance of the above-mentioned devices is usually long during continuous rolling. Debris in the plant environment will adhere to the surface of the metal plate during transportation, thereby damaging the surface of the steel plate during the rolling process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a six-stand continuous rolling mill for tinplate production, which uses a conveying device to transport metal plates during the continuous rolling process, a cleaning device to clean the surface of the metal plates, and a drying device to dry the surface of the metal plates, thereby reducing the impact of residual liquid on the surface of the metal plates on subsequent processing and improving the practicality of the device.

[0006] This utility model discloses a six-stand continuous rolling mill for tinplate production; it includes a conveying device, a cleaning device, and a drying device. The cleaning device is installed on the conveying device, and the drying device is installed on the conveying device. The conveying device transports the metal sheet during the continuous rolling process, the cleaning device cleans the surface of the metal sheet, and the drying device dries the surface of the metal sheet, thereby reducing the impact of residual liquid on the surface of the metal sheet on subsequent processing and improving the practicality of the device.

[0007] Preferably, the conveying device includes a conveyor frame, a single rolling mechanism, conveying rollers, and a first reduction motor. The single rolling mechanism is installed on the left side of the conveyor frame, and multiple sets of conveying rollers are horizontally installed on the conveyor frame. Multiple sets of first reduction motors are installed on the front end face of the conveyor frame, and the output ends of the multiple sets of first reduction motors are respectively connected to the multiple sets of conveying rollers. The multiple sets of conveying rollers carry and assist in the transportation of the metal sheet during the continuous rolling process. The first reduction motor is turned on to transmit power to the conveying rollers connected to it, thereby driving the conveying rollers to rotate and thus providing assistance for the transportation of the metal sheet. The single rolling mechanism processes the metal sheet, improving the practicality of the device.

[0008] Preferably, the device also includes a cleaning frame, an upper cleaning roller, and a second geared motor. The upper cleaning roller is mounted on the upper end face of the conveyor frame via the cleaning frame, and the second geared motor is mounted on the front end face of the cleaning frame. The output end of the second geared motor is connected to the upper cleaning roller. When the second geared motor is turned on, power is transmitted to the upper cleaning roller to drive the upper cleaning roller to rotate, thereby assisting in cleaning the upper surface of the metal sheet, reducing the dirt adhering to the upper surface of the metal sheet, and improving the practicality of the device.

[0009] Preferably, the cleaning device includes an electric cylinder, a U-shaped frame, a lower cleaning hole roller, auxiliary support wheels, and a third reduction motor. An electric cylinder is installed on the lower end face of the conveyor frame, and a U-shaped frame is installed on the moving end of the electric cylinder. The lower cleaning hole roller is horizontally installed on the U-shaped frame. A set of grooves is provided at the front and rear of the upper end face of the U-shaped frame, and auxiliary support wheels are installed in the grooves. A third reduction motor is installed on the rear end face of the U-shaped frame, and the output end of the third reduction motor is connected to the lower cleaning hole roller. The U-shaped frame is located between two adjacent sets of conveyor rollers. By controlling the extension of the electric cylinder, the height of the U-shaped frame is controlled, allowing the lower cleaning hole roller to contact the lower end face of the metal sheet. The third reduction motor is activated to transmit power to the lower cleaning hole roller, causing it to rotate and thus cleaning the lower end face of the metal sheet. Multiple sets of auxiliary support wheels provide auxiliary support to the metal sheet, preventing excessive pressure between the lower cleaning hole roller and the metal sheet from causing equipment damage, thus improving the practicality of the device.

[0010] Preferably, the air-drying device includes a gantry, a fan, a V-shaped mounting bracket, strip nozzles, and a pressurizing nozzle. The gantry is installed on the upper surface of the conveyor frame, located on the right side of the upper cleaning frame of the U-shaped frame. The fan is installed on the upper surface of the gantry, and a V-shaped mounting bracket is installed on the top surface of the gantry, with the tip of the V-shaped mounting bracket pointing to the left. A set of strip nozzles is inclinedly arranged at the front and back of the lower part of the V-shaped mounting bracket, and a pressurizing nozzle is installed at the left tip of the V-shaped mounting bracket. The fan is turned on to pressurize the outside air and deliver it to the strip nozzles and pressurizing nozzles. The airflow from the pressurizing nozzles splits the liquid on the upper surface of the metal plate to the left and right, and the gas from the two sets of strip nozzles blows the liquid off the plate from both sides. The V-shaped mounting bracket itself is designed to reduce liquid residue on the metal plate, improving the practicality of the device.

[0011] Preferably, the device also includes a mounting plate, rinsing nozzles, a storage tank, and a water pump. The mounting plate is installed at an angle on the left side of the cleaning frame, and multiple sets of rinsing nozzles are evenly installed on the lower end of the mounting plate. A storage tank is installed on the rear end of the conveyor frame, and a water pump is installed on the storage tank.

The cleaning liquid is stored in the storage tank, and the water pump is turned on to extract and pressurize the cleaning liquid before sending it to the rinsing nozzles for spraying, thereby rinsing the upper cleaning roller and the upper end of the metal plate. This reduces manual maintenance costs and improves the practicality of the device.
