Technical Field

[0001] The invention relates to an oil scraper device, in particular to an oil scraper device for coating polyester tire base cloth. Background Art

[0002] The coating machine is a key equipment in the existing process of modified asphalt waterproofing membrane with tires. The function of the coating machine is to dip the modified material on the tire base fabric such as non-woven fabric to form a coiled material, so that it reaches the set thickness and ensures the uniform thickness of the coiled material. The modified material is a mixture of rubber, resin, high molecular polymer, rubber powder, oxidized asphalt or other fillers. After heating to 180 degrees Celsius, it is dipped onto the tire base fabric through roller extrusion in the coating machine. Some substances in the modified material are easy to agglomerate and adhere to the rollers, resulting in an uneven surface of the coiled material, affecting the appearance and quality of the finished product.

[0003] The existing technical solution is to set a scraper on the roller, and the scraper is tightened by multiple sets of springs to continuously scrape impurities on the surface of the roller. Under long-term high-temperature operation, the spring deformation causes uneven force on the scraper, and the scraping effect is reduced. It is necessary to stop work frequently to adjust or replace the spring of the scraper. Summary of the invention

[0014] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1 As shown, the figure includes a coating machine archway frame 3, on which two coating machine rollers 5 are installed, which are arranged upper and lower. Each coating machine roller 5 is connected to a roller traction reducer 2, and the upper ends of the coating machine rollers 5 above the coating machine archway frame 3 are connected to the extrusion reducer 4. The unwinding side of the coating machine archway frame 3 is provided with two sets of coating machine scraper groups, which include a coating machine scraper 9, a bearing seat 7, an adjustable cylinder 8, a support plate 10 and a 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, and 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.

[0016] The two sets of coating machine scraper knife groups are respectively located above and below the roll-out side of the coating machine archway frame 3.

[0017] The support plate 10 is provided with a bend, which fits the bearing of the bearing seat 7. The support plate 10 plays a supporting role, and the bearing seat 7 provides a fulcrum for the movement of the oil scraper of the coating machine. When the bearing seat 7 rolls, the upper and lower positions are adjusted through the provided bend.

[0018] The coating machine scraper 9 is fixed on the heater 6 by bolts. The electric heating plate 6 heats the scraper to 200 degrees Celsius to heat and scrape off the impurities adhered to the roller.

[0019] The bearing seat 7 is fixed to the side of the coating machine archway frame 3 by bolts. The bearing seat 7 provides a fulcrum for the movement of the coating machine scraper knife. The adjustable cylinder is connected to the coating machine scraper knife support plate.

[0020] The coating machine rollers 5 are installed on the coating machine archway 3 and are rotated by the roller traction reducer 2, wherein the upper rollers can move up and down under the traction of the extrusion reducer 4; the tire base cloth enters the coating machine archway 3 from the left side after being impregnated with the modified material in the coating machine oil pool to form a coil 1, and goes out from the right side after being pressed by two coating machine rollers 5, and the winder of the production line provides power for the coil; there are two sets of coating machine scraper knives, both of which are installed on the unwinding side of the coating machine archway. The coating machine scraper knives are mainly divided into three parts, including scrapers, electric heating plates, and support plates. The coating machine scraper knives 9 are made of brass, and the upper end thereof is provided with waist-shaped holes with adjustable installation positions, which are respectively at a certain angle to the roller surfaces of the coating machine rollers. The electric heating plate can heat the scraper to 200 degrees Celsius, and the support plate plays a supporting role. The bearing seat provides a fulcrum for the movement of the coating machine scraper knife, and the adjustable cylinder is connected to the coating machine scraper knife support plate.

[0021] During operation, the coil 1 moves under the traction of the winder, and the coating machine rollers 5 rotate in the opposite direction to the moving direction of the coil to press the coil; as needed, the extrusion reducer 4 can control the upper coating machine rollers 5 to move up and down to adjust the thickness of the coil; the electric heating plate 6 at the coating machine scraper 9 heats the scraper to 200 degrees Celsius to heat and scrape off the impurities adhered to the rollers. The scraper is made of brass and will wear itself during the process of scraping impurities without wearing the roller surface. The scraper can adjust the installation position; regardless of whether the scraper is worn, the cylinder can control the coating machine scraper to always form a certain angle with the roller surface of the coating machine through telescopic control to ensure the scraping effect, which will not affect the operation of the production line.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
