Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment manufacturing, in particular to a roller coating machine with a lifting device. Background Art

[0002] With the development of plate and strip coating technology, the use of roller coaters has increased day by day, and the demand for roller coaters' coating effects has also gradually increased. The wrap angle between the coating roller and the support roller is one of the important factors affecting the coating quality. At present, the support rollers of roller coaters are all fixed. Roller coaters with fixed support rollers have the following defects: 1. When the plate and strip pass through, the plate and strip weld will rub against the roller surface, resulting in a reduction in the service life of the support roller; 2. After the plate and strip are formed and sliced, the fixed support roller will have some uneven defects, which greatly affects the quality of the plate and strip. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a roller coater with a lifting device to achieve adjustable wrap angles between the coating roller and the support roller.

[0004] To achieve the above-mentioned purpose of the invention, the linear guide rails of the present invention are installed on both sides of the support roller frame, the elevator is fixed on the support roller frame, the elevator is connected to the bottom of the bearing seat on both sides of the support roller, the bearing seat is supported on the linear guide rail through the elevator, the bearing seat is connected to the guide rail slider through the hexagon socket screw, and is driven by the elevator to perform lifting and lowering movements on the linear guide rail together with the guide rail slider; the support roller is installed and fixed on the bearing seat, the support roller moves with the bearing seat, and the lifting and lowering of the support roller makes the plate strip form the required wrap angle a with the coating roller during the back coating process; the elevators on both sides are connected by a synchronization mechanism; the scraper is connected to the end face of the bearing seat through the scraper support plate with the hexagon socket screw, so that the scraper is lifted and lowered together with the bearing seat when the support roller is lifted and lowered, and a liquid receiving pan for collecting the coating liquid scraped from the support roller is placed under the scraper.

[0005] Furthermore, the bearing seat is embedded with a bearing and is tightened by a bearing seat cover. One end of the bearing seat cover is fixed with a pin and a nut, and the other end is fixed by a ring nut. A stop washer is installed on the outside of the bearing and is fixed to the bearing seat by a round nut.

[0006] Furthermore, a U-shaped groove is provided on the scraper support plate for adjusting the distance of the scraper, and a gasket for pressing the scraper is provided above the scraper.

[0007] Furthermore, openings are provided on both sides of the support roller frame for facilitating installation and maintenance of the scraper and cleaning and replacement of the liquid receiving tray.

[0008] Compared with the prior art, the present invention has the following advantages: Under the premise of meeting the coating working requirements of the roller coater, the supporting roller component of the traditional roller coater is designed to be liftable, so that the elevator drives the supporting roller to rise and fall, and can adjust the wrap angle of the plate and strip passing through the coating roller during back coating, so that the wrap angle between the coating roller and the supporting roller can be adjusted, which can effectively ensure the forming quality and coating quality of the plate and strip.

[0009] A scraper device is added to the support roller. The scraper can move up and down together with the support roller, and can promptly clean the coating liquid flowing from the plate strip to the end surface of the roller, thus ensuring the stability of the roller coating machine operation.

[0010] An opening structure is designed on the support roller frame, which is very convenient for the installation, use, maintenance and replacement of the scraper, and is also easy to clean and replace the liquid receiving tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the roller coating machine with a lifting device of the present invention is mainly used for the supporting roller mechanism therein. The linear guide 7 is installed on both sides of the support roller frame 1, and the lifter 8 is fixed on the support roller frame 1. The lifter 8 is connected to the bottom of the bearing seat 3 on both sides of the support roller 2. The bearing seat 3 is supported on the linear guide 7 through the lifter 8. The bearing seat 3 is connected to the guide slider 9 through the hexagon socket screw and driven by the motor. The lifter 8 drives the guide slider 9 to perform lifting and lowering movements on the linear guide 7. The movement of the linear guide 7 can effectively ensure the movement accuracy of the support roller 2; the bearing seat 3 is embedded with a bearing 5 and is pressed by a bearing seat pressure cover 11. One end of the bearing seat pressure cover 11 is fixed with a latch 12 and a nut 13, and the other end is fixed by a ring nut 14. After the ring nut 14 is screwed out, the bearing seat pressure cover 11 can be quickly opened, so that the support roller 2 has a quick change function. A stop washer is installed on the outside of the bearing 5, and it is fixed to the bearing seat 3 through a round nut 15; the support roller 2 is installed and fixed on the bearing seat 3. After the support roller 2 is fixed on the bearing seat 3, it can be lifted and lowered with the lifting of the bearing seat 3. The lifting and lowering of roller 2 can make the strip form the required wrap angle a with the coating roller 17 during the back coating process to ensure the coating quality of the strip; the elevators 8 on both sides are connected by a synchronization mechanism 10, which can effectively ensure the stability of the lifting and lowering of the support roller 2; the scraper 4 is connected to the end face of the bearing seat 3 through the scraper support plate 16 with a hexagon socket screw, so that the scraper 4 can be lifted and lowered together with the bearing seat 3 when the support roller 2 is lifted and lowered. The scraper 4 can be lifted and lowered together with the support roller 2, and can timely clean the coating liquid that flows from the edge of the strip to the end face of the support roller 2 ; A liquid receiving tray 6 for collecting the coating liquid scraped from the support roller 2 is placed below the scraper 4 to avoid splashing of the coating liquid; a U-shaped groove is provided on the scraper support plate 16 for adjusting the distance of the scraper 4, so that the scraper 4 can touch the roller surface of the support roller 2 well, and a gasket for pressing the scraper 4 is provided above the scraper 4 to increase the connection strength between the scraper support plate 16 and the scraper support plate 16; openings 18 are provided on both sides of the support roller frame 1 to facilitate the installation and maintenance of the scraper 4, and to facilitate the cleaning and replacement of the liquid receiving tray 6.
