Embodiment Construction

[0036] Such as Figures 1 to 3 As shown, a device for reducing stickies of yellow board paper includes a scraper mechanism 3 for removing stickies on the drying cylinder 1 of a paper machine;

[0037] Described scraper mechanism 3 comprises the connection frame 31 that is fixedly connected on the frame of paper machine, the turret 32 ​​that is installed in the connection frame 31 and the scraper 33 that middle shaft is connected on the turret 32, and a plurality of air bag cylinders 34 are installed Between the turret 32 ​​and the scraper 33; each airbag cylinder 34 pushes one end of the scraper 33 to stick on the surface of the drying cylinder 1, and inflates the airbag cylinder 34 to push the scraper 33 to tilt toward the drying cylinder 1, so that the scraper The plate 33 can be attached to the surface of the drying cylinder 1 in real time, and the sticky matter adhered to the surface of the drying cylinder 1 is cleaned by using the scraper 33 to prevent the sticky matter f...

Abstract

The invention provides a reducing device and method for sticky substances for straw board paper. The device comprises a scraping mechanism used for removing the sticky substances on a paper machine drying cylinder; the scraping mechanism comprises a connecting frame fixedly connected with a paper machine frame, a rotating frame installed in the connecting frame, a scraping plate of which the middle shaft is connected with the rotating frame and a plurality of air cylinders installed in the connecting frame; and each air cylinder pushes one end of the scraping plate to be attached to the surface of the drying cylinder. The device and method provided by the invention are used for solving the problems that the straw board paper is easy to break and then void holes appear due to adhesion of the sticky substances in the drying process of the sticky substances.

Description

technical field [0001] The invention relates to a device and method for reducing stickies of yellow cardboard. Background technique [0002] With the multiple recycling of raw materials for packaging paper production (domestic yellow cardboard), the cumulative increase of stickies in cartons during the pulping process, coupled with the limited means of removing stickies from pulping equipment, has resulted in paper machines being in use When waste paper is used as the main raw material for the slurry, the normal production will be affected by sticky matter in the press section and drying section, mainly manifested as adhesion on the surface of the forming wire and press felt, affecting the dehydration efficiency of the mesh blanket, and causing voids in the paper sheet formation . At the same time, the adhesion of the sticky matter in the drying section increases due to the temperature rise, which causes serious blockage of the mesh mesh and affects the drying effect, until...
