Technical Field

[0001] This utility model relates to an oil scraper device, and more particularly to an oil scraper device with polyester base fabric coating. Background Technology

[0002] The existing process for fabricated modified bitumen waterproof membranes includes a key piece of equipment: a coating machine. The coating machine's function is to impregnate a base fabric (such as non-woven fabric) with the modified material to form the membrane, achieving the set thickness and ensuring uniform thickness. The modified material is a mixture of rubber, resin, polymer, rubber powder, oxidized bitumen, or other fillers. After being heated to 180 degrees Celsius, it is applied to the base fabric by extrusion through rollers in the coating machine. Some components of the modified material tend to clump and adhere to the rollers, resulting in an uneven surface on the membrane, affecting the appearance and quality of the finished product.

[0003] The existing technical solution involves installing oil scrapers on the rollers, with the scrapers held in place by multiple sets of springs to continuously scrape away impurities from the roller surface. Under prolonged high-temperature operation, spring deformation causes uneven force on the oil scrapers, reducing their scraping efficiency and requiring frequent shutdowns to adjust or replace the scraper springs.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0016] like Figure 1As shown in the figure, the coating machine frame 3 is included. Two coating machine rollers 5 are installed on the coating machine frame 3, one above the other. Each coating machine roller 5 is connected to a roller traction reducer 2. The upper end of the coating machine roller 5 above the coating machine frame 3 is connected to an extrusion reducer 4. Two sets of coating machine scraper assemblies are provided on the coil exit side of the coating machine frame 3. The coating machine scraper assemblies include coating machine scraper 9, bearing seat 7, adjustable cylinder 8, support plate 10 and heater 6. The front end of the support plate 10 is connected to the heater 6, and the coating machine scraper 9 is fixedly connected to the heater 6. The coating machine scraper 9 is attached to the edge of the coating machine roller 5. The rear end of the support plate 10 is connected to the adjustable cylinder 8, and the support plate 10 is attached to the bearing seat 7.

[0017] The two sets of oil scraper assemblies for the coating machine are located above and below the roll-out side of the coating machine frame 3, respectively.

[0018] The support plate 10 has a bend that fits into the bearing of the bearing housing 7. The support plate 10 provides support, and the bearing housing 7 provides a fulcrum for the movement of the oil scraper of the coating machine. When the bearing housing 7 rolls, its vertical position is adjusted by the bend.

[0019] The coating machine scraper 9 is fixed to the heater 6 by bolts. The electric heating plate 6 heats the scraper to 200 degrees Celsius to heat and scrape off the impurities adhering to the rollers.

[0020] The bearing housing 7 is fixed to the side of the coating machine frame 3 by bolts. The bearing housing 7 provides a fulcrum for the movement of the coating machine scraper blade. The adjustable cylinder is connected to the coating machine scraper blade support plate.

[0021] The coating machine rollers 5 are mounted on the coating machine frame 3 and rotated by the roller traction reducer 2. The upper roller can move up and down under the traction of the extrusion reducer 4. After the base fabric is impregnated with modified materials in the coating machine oil bath to form a roll 1, it enters the coating machine frame 3 from the left side. After being pressed by the two coating machine rollers 5, it exits from the right side. The winding machine of the production line provides power for the roll. There are two sets of coating machine scrapers, both installed on the roll exit side of the coating machine frame. The coating machine scraper is mainly divided into three parts, including the scraper, the electric heating plate, and the support plate. The coating machine scraper 9 is made of brass and has an adjustable waist-shaped hole at the upper end, which is at a certain angle to the roller surface of the coating machine rollers. The electric heating plate can heat the scraper to 200 degrees Celsius. The support plate provides support, and the bearing seat provides a fulcrum for the movement of the coating machine scraper. The adjustable cylinder is connected to the coating machine scraper support plate.

[0022] During operation, the roll 1 moves under the traction of the winding machine, and the coating machine rollers 5 rotate in the opposite direction to the roll's movement to press it down. As needed, the extrusion reducer 4 can control the up and down movement of the coating machine rollers 5 above to adjust the roll thickness. The electric heating plate 6 at the coating machine scraper 9 heats the scraper to 200 degrees Celsius, heating and scraping away impurities adhering to the rollers. The scraper is made of brass and will wear itself during the scraping process without wearing down the roller surface. The scraper's installation position can be adjusted. Regardless of whether the scraper is worn, the cylinder can control the coating machine scraper to always maintain a certain angle with the coating machine roller surface through extension and retraction to ensure the scraping effect without affecting the operation of the production line.
