Deslagging scraper device for oven return roller

Abstract

The invention provides a deslagging scraper device for an oven return roller, and relates to the technical field of papermaking equipment. The deslagging scraper device comprises a driving roller, a return roller, a drive chain, an adjusting chain wheel, a scraper part and an adjusting part, wherein the scraper part comprises a scraper, a scraper seat, a scraper shaft and an adjusting piece; the adjusting part comprises an upper fixing frame connected with the oven wall, a lower fixing frame connected with the adjusting piece and a connecting frame for connecting the upper fixing frame and thelower fixing frame; an adjusting support plate is arranged on the upper fixing frame, an adjusting screw is arranged on the adjusting support plate, and a tension spring connected with the scraper shaft is connected to the end, away from the adjusting support plate, of the adjusting screw; the lower fixing frame rotates around the joint with the connecting frame. The deslagging scraper device forthe oven return roller has simple structure, can clean residual adhesives on the surface of the return roller in real time, does not need an operator to hold a cleaning tool to clean the surface of the return roller, ensures continuity of production, increases the automation degree of the device, and reduces potential safety hazards.

Description

Technical field [0001] The invention relates to the technical field of papermaking equipment, [0002] In particular, the present invention relates to a scraper device for removing dross from the turning back roll of an oven. Background technique [0003] In the production process of paper-making flakes, the flakes are sequentially coated, dried, formed, pre-pressed, packaged, and bundled along with the netting, guide belt, and conveyor belt. Finally, the finished flakes are transported to the finished product warehouse for storage. [0004] After the coated substrate paper enters the drying process, the coating liquid will adhere to the drying net, the guide belt, and the conveyor belt during the transportation of the paper. Due to the absorbent capacity of the netting itself and the adhesion of the coating liquid, the paper will change The drying net, the guide belt, and the conveyor belt enter the oven, and then into the gap between the tension return roller and the clothing, so ...

AI Technical Summary

Problems solved by technology

[0004] The coated substrate paper enters the drying process, and the coating liquid will adhere to the dry net, guide belt, and conveyor belt during the conveying process of the paper. Due to the adsorption capacity of the net blanket itself and the adhesion of the coating liquid, the paper will The dry web, guide belt, and conveyor belt enter the oven, and then enter the gap between the tensioning return roller and the net blanket, so that the paper is wound around the tensioning return roller, resulting in an increase in the shaft diameter of the tensioning return roller, and the blanket is too tense , prone to deviation or tearing of the net blanket

When the paper winding of the tensioning return roller is serious and the bearing becomes larger, the service life of the net blanket, guide belt, conveyor belt, and guide roller will be greatly reduced; The wrapped paper on the surface is not easy to clean, which is easy to cause mechanical damage and poses a safety hazard; the paper machine needs to be shut down to replace the tensioning return roller, which will affect the continuity of production and production efficiency, and will cause waste of manpower, material resources and energy
