[0002] The bending straightening machine has a good correction effect on the plate shape of the plate. However, in the straightening process of galvanized plates, due to the bending and stretching of the plate by the bending straightening machine, as well as the rolling friction between the roller and the plate, the zinc powder of the galvanized plate is very easy to fall off and stick to the roller of the bending straightening machine. Over time, it will accumulate, thus affecting the straightening performance of the bending straightening machine.

[0003] The usual solution to the problem of zinc powder sticking to the rollers of galvanized strips is to replace the spare roller box, and then manually clean and maintain the rollers, or use felt to clean the rollers. However, both methods are time-consuming and labor-intensive, affecting the production and processing efficiency and capacity of the strips, and the results are not ideal. First of all, disassembling and assembling the roller box to clean the rollers is troublesome in operation, and the maintenance time is short.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the cleaning device of the wet stretch-bending and straightening machine 5 of the utility model mainly includes a spray device 1, a scraper device 2, a sealing and draining device 3, and a purging device 4; the spray device 1 is located on the transmission side of the wet stretch-bending and straightening machine 5, the scraper device 2 is installed at the inlet and outlet turning rollers of the wet stretch-bending and straightening machine 5, the sealing and draining device 3 wraps and seals the wet stretch-bending and straightening machine 5 except for the channel through which the plate and strip pass, and the purging device 4 is located on the outlet side of the wet stretch-bending and straightening machine 5.

[0021] The roller surfaces of all roller systems of the wet tension and bending straightening machine 5 are chrome-plated. The chrome plating of the rollers has the functions of enhancing the surface hardness of the rollers, preventing rust and corrosion, and improving the smoothness of the roller surface. For galvanized strips, a smoother roller surface helps to reduce the adhesion of the roller surface and reduce the adhesion of zinc powder. Therefore, roller chrome plating is a good measure to improve the process of galvanized strip straightening equipment.

[0022] Spraying helps to clean the rollers and strips, remove the zinc powder that falls off the strips, and the zinc powder that sticks to the rollers, and prevent dust from flying. The main spray pipe 1-7 of the spray device 1 is installed with an automatic control valve 1-2 and a manual control valve 1-1 for controlling the opening and closing of the water circuit, as well as a flow meter 1-3 for detecting the water speed. The branch spray pipe 1-5 includes a branch valve 1-4 and a plurality of nozzles 1-6 for controlling the interruption of the branch water flow. The branch spray pipes 1-5 are respectively located above and below the strips, passing from the transmission side of the wet straightening machine 5 to the operating side, and the main spray pipe 1-7 is fixed on the frame of the wet straightening machine 5. Usually, there are seven branch spray pipes 1-5, four above the strips and three below the strips, which can be increased according to actual requirements. During use, the automatic control valve 1-2, the manual control valve 1-1 and the branch valve 1-4 are opened, and water flows through the main spray pipe 1-7 into each branch spray pipe 1-5, and finally sprays out from each nozzle 1-6 in a fan shape, flushing the detached zinc powder into the sealed drainage device 3 for discharge.

[0023] The mounting hole at one end of the scraper 2-1 of the scraper device 2 is sleeved on the output shaft of the hand-cranked reduction motor 2-2, and the other end is mounted on the bearing seat 2-3. The hand-cranked reduction motor 2-2 controls the blade of the scraper 2-1 to be close to the roller surface of the steering roller or separated from the roller surface of the steering roller. The hand-cranked reduction motor 2-2 and the bearing seat 2-3 are fixed on the bracket of the wet tension bending straightening machine 5. There are pneumatic control and mechanical control for the control of the scraper 2-1. This embodiment is a mechanically controlled scraper device 2. For the problem that the steering roller is difficult to disassemble and thus the sticky zinc powder is difficult to clean, the utility model adopts, in addition to the roller chrome plating, the installation of a scraper device 2 to clean the zinc powder. It is simple to use and has a good cleaning effect.

[0024] The sealing drainage device 3 is composed of an upper sealing plate 3-4 on the operating side, an upper sealing plate 3-1 on the transmission side, a lower sealing plate 3-8 on the operating side, a lower sealing plate 3-2 on the transmission side, a top cover plate 3-5, a water receiving trough 3-6, an operating side side plate 3-7, a transmission side side plate 3-3, a lower lifting device sealing cover 3-11, a water collecting trough 3-9, an operating side sealing door 3-12, a transmission side sealing door 3-13, and a water outlet flange 3-10; the upper sealing plate 3-4 on the operating side, the upper sealing plate 3-1 on the transmission side, the lower sealing plate 3-8 on the operating side, the lower sealing plate 3-2 on the transmission side, the top cover plate 3-5, the operating side side The plate 3-7, the transmission side side plate 3-3, the lower lifting device sealing cover 3-11, the operating side sealing door 3-12, and the transmission side sealing door 3-13 wrap and seal the wet tension and bending straightening machine 5, the water receiving trough 3-6 is connected to the outer wall of the operating side and transmission side frames of the wet tension and bending straightening machine 5, the operating side and the transmission side of the water receiving trough 3-6 are respectively connected to one end of the operating side side plate 3-7 and the transmission side side plate 3-3 through a hose, and the other end of the operating side side plate 3-7 and the transmission side side plate 3-3 is connected to the water collecting trough 3-9, and the outlet flange 3-10 is arranged below the water collecting trough 3-9, which is more conducive to the discharge of waste liquid. The spray liquid of the spray device 1 is sprayed out from the nozzle 1-6 and flows directly into the water collection tank 3-9 through the plate strip. Some of the waste liquid splashed outside the wet bending straightening machine 5 is discharged into the operating side plate 3-7 and the transmission side plate 3-3 through the water receiving tank 3-6 by the hose, and then flows into the water collection tank 3-9, and finally discharged from the outlet flange 3-10 to the circulation system for reuse. The waste liquid generated in the production process is no longer collected after passing through multiple places, but directly enters the water collection tank 3-9 and then discharged into the circulation system, which plays a good role in dust prevention and splash prevention, and effectively protects the cleanliness of the production environment.

[0025] The main purge pipe 4-7 of the purge device 4 is fixed on the frame of the wet-type straightening machine 5. The main purge pipe 4-7 is connected to one end of the hose 1 4-2 and the hose 2 4-3 through the three-way joint 4-1. The other ends of the hose 1 4-2 and the hose 2 4-3 are connected to one end of the purge pipe 1 4-4 and the purge pipe 2 4-5 respectively. The other ends of the purge pipe 1 4-4 and the purge pipe 2 4-5 pass through the wet-type straightening machine 5, are fixed on the frame of the wet straightening machine 5, and are connected to the plug 4-6. The purge pipe 1 4-4 and the purge pipe 2 4-5 are respectively located above and below the plate strip. During the processing of the plate strip, the running speed is relatively fast. During the spraying process, it is inevitable that some spray liquid will not be discharged in time and will be carried out of the equipment by the plate strip, causing waste liquid to splash out, or be carried into the next process, thereby causing the subsequent equipment without anti-rust measures to rust. The blowing device 4 of the utility model can use wind power to blow the waste liquid into the wet stretch bending straightening machine 5, and at the same time air dry the plate strip.
