Description

[Technical field]

[0001] The utility model relates to a paper web thickness adjustment technology in papermaking, in particular to a bidirectional adjustment and deviation adjustment device for a coating machine. [Background technology]

[0002] In the papermaking industry, a coater is a device used to coat a layer of specified material on the surface of a material. As an important component of the coater, once the tension roller of the coater deviates, it will directly affect the production quality and even endanger the normal service life of the equipment.

[0003] However, in the papermaking process, due to the influence of many factors such as the pulp feeding method, the accuracy of the forming area, the difference in dehydration rate of different areas of the wire surface and the felt, concentration fluctuations, the height and wear of each pressing roller, and the difference in drying intensity in different areas of the drying section, the paper web has uneven cross-section thickness. Since the existing coating machine can only be adjusted in a single vertical direction, this unevenness is difficult to adjust, resulting in inconsistent cross-section thickness of the paper web, and serious quality problems such as shaking and wrinkling of the paper web at the tensioning roller, which affects the production quality of the paper web. [Contents of the utility model]

[0004] The utility model provides a bidirectional adjustment and deviation adjustment device for a coating machine, which effectively overcomes the problems of shaking and wrinkling in the paper web forming process, ensures that the banner thickness of the output paper web is uniform, and effectively improves the production quality and production efficiency of paper.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A vertical adjustment mechanism for adjusting the longitudinal displacement of the operating side bearing and the tensioning roller in the vertical direction according to the paper width is installed on the inner side of the operating side bearing frame seat perpendicular to the paper feeding direction;

[0008] A horizontal adjustment mechanism is installed on the inner side of the transmission side bearing frame seat in parallel with the paper feeding direction to adjust the lateral displacement of the transmission side bearing and the tensioning roller in the horizontal direction according to the paper format.

[0009] Preferably, the vertical adjustment mechanism includes an operating side bearing positioning seat, an operating side adjusting screw, an operating side adjusting hand wheel and an operating side reverse locking wheel, the operating side bearing positioning seat is provided with a sliding groove for the operating side bearing to move up and down in the vertical direction, the operating side adjusting screw is threadedly connected to the top side of the operating side bearing positioning seat, and the lower end of the operating side adjusting screw is rotatably connected to the top of the operating side bearing, the operating side adjusting hand wheel is fixed to the top end of the operating side adjusting screw, the operating side adjusting screw is driven by the operating side adjusting hand wheel to move forward and reversely, driving the operating side bearing in the sliding groove to move up and down in the vertical direction, and after the operating side bearing is in place, the operating side reverse locking wheel on the operating side adjusting screw rotates in the opposite direction and abuts against the top end surface of the operating side bearing positioning seat to lock the operating side adjusting screw and the operating side bearing connected thereto.

[0010] Preferably, the horizontal adjustment mechanism includes a transmission side bearing positioning seat, a transmission side adjusting screw, a transmission side adjusting hand wheel and a transmission side reverse locking wheel. A sliding groove for the transmission side bearing to be displaced forward and backward in the horizontal direction is provided in the transmission side bearing positioning seat.

[0011] The beneficial effects of the utility model are:

[0012] In view of the problem that the tensioning roller of the existing coating machine can only be adjusted in one direction, the tensioning roller is manually adjusted by means of a vertical adjustment mechanism and a horizontal adjustment mechanism, which can be displaced up and down in the vertical direction and forward and backward in the horizontal direction respectively, thereby realizing the vertical longitudinal and horizontal transverse adjustment of the tensioning roller during coating, effectively solving the quality problems of paper web shaking and wrinkling at the tensioning roller, ensuring that the banner thickness of the output paper web is uniform, and effectively improving the production quality and efficiency of paper.
