Paper web stabilizer of high-speed paper machine

Abstract

The invention discloses a paper web stabilizer for a high-speed paper machine. A windpipe in parallel with the axis center of a baking cylinder is arranged between the baking cylinder and a vacuum roller; the windpipe is divided into a blowing area and a suction area; the suction area is uniformly provided with three rows of suction holes with the diameter of 10-80mm and the spacing of 40-60mm atthe lower end and two sides of the windpipe; a paper guide area occupying 1 / 3 of the pipe length at one end of the windpipe is internally provided with an open / close valve; the blowing area is provided with a blowing pipe at the center of the windpipe; the inlet of the blowing pipe connected with a fan is arranged at one end of the windpipe; the circumference of the windpipe is welded and assembled with a partition plate by a steel plate; the wind in the blowing pipe flows by a space formed by the partition plate through the outlet at the middle part of the windpipe and blows out of a wind nozzle formed by the partition plate seam through the upper end and the lower end of the windpipe. When guiding the paper, the paper guide area can be separated from other areas, thus ensuring the paperto be closely attached to a dry blanket; the produced paper generates no rumple and is not easy to be broken; furthermore, the speed of the paper machine can be improved and paper guiding without rope can be realized.

Description

technical field [0001] The invention relates to a web stabilizer for a high-speed paper machine. Background technique [0002] Existing high-speed paper machines are mainly only equipped with a single row of drying cylinders and vacuum rolls, which have the following disadvantages: during the transfer process of the paper sheets between the drying cylinders and vacuum rolls, the paper sheets cannot stick to the dry felt, and will float away from the dry felt, causing Air pockets are formed in the paper sheet, causing paper to wrinkle; and it is easy to break the paper; the speed of the whole paper machine is slow, and paper threading is difficult. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a high-speed paper machine web stabilizer. In order to realize that the paper sheet can be closely attached to the dry felt, no air pockets will be formed, and the produced paper will not produce wrinkles; th...
