Abstract

The utility model relates to a doctor for a drying cylinder, which comprises a blade, pressing marks, a doctor bracket and a power device, wherein, the utility model has a plurality of pressing marks which are not contacted mutually. The pressing marks is rotationally connected with the doctor bracket, and an air bag is arranged between the pressing marks and the doctor bracket. The blade fully attaching to the surface of the drying cylinder as the accidented fluctuation of the surface of the dry cylinder is guaranteed. Thereby, the wrinkle rate is improved.

Description

Scraper

The utility model relates to a kind of drying cylinder scraper.

Present common drying cylinder scraper, generally by blade, press mark, doctor blade holder, compositions such as power set, wherein blade inserts and presses in the mark, pressure is designated as one, and it is fixed on the doctor blade holder, and doctor blade holder is connected with power set, it is manual or electronic that power set mostly are, under the effect of power set, blade is with pressing mark and doctor blade holder together to rotate, and sticks or breaks away from the drying cylinder face, stick on blade on the drying cylinder to the effect of curl folding, perhaps the cylinder face is played scavenging action, after the scraper of this structure, scraper stick on the drying cylinder face, when the concavo-convex fluctuating of drying cylinder face, blade can not rise and fall thereupon, therefore can not can not effectively remove the cylinder face effectively to the paper wrinkle; Have, the manual power device operates more loaded down with trivial details again, and electric power device is easy and simple to handle, but its adjustment precision often is weak.

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of blade that can make fully to stick on the drying cylinder face, thereby improves the scraper of tortuosity and clear cylinder effect.

Another purpose of the present utility model is to provide a kind of powered device easy, adjusts the high scraper of precision.

The utility model is achieved in that it comprises blade, presses mark, doctor blade holder, power set, and wherein the blade insertion is pressed in the mark, presses mark to be connected with doctor blade holder, and doctor blade holder is connected with power set, and pressure indicates a plurality of, and does not contact mutually; Press mark to be connected with random blade holder turns, pressing between mark and the doctor blade holder has an air bag.

Adopt the utility model,, can guarantee that blade is with the concavo-convex fluctuating of drying cylinder face by air bag and the leverage of pressure target, fully stick on the drying cylinder face, thereby improve tortuosity and clear cylinder effect, adopt the pneumatic power device not only easy and simple to handle, and the requirement that sticks of be content with very little blade and drying cylinder face.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view of Fig. 1;

Fig. 3 is the structural representation of support plate in the utility model;

Fig. 4 is the cutaway view of Fig. 3.

Referring to accompanying drawing, with 1575 paper machine scrapers is example, the utility model comprises blade 1, presses mark 2, doctor blade holder 3, power set 4, wherein press mark 2 to have 39, press mark 2 not contact each other, blade 1 inserts presses in the mark 2, press between mark 2 and the doctor blade holder 3 support plate 5 is arranged, this support plate 5 is fixed on the doctor blade holder 3 by screw, 19 continuously arranged connecting plates 51 are arranged at support plate 5 tops, this connecting plate 51 is provided with pin-and-hole 52, and the pressure mark place corresponding with connecting plate pin-and-hole 52 is provided with corresponding pressure mark pin-and-hole 21, and support plate 5 is rotationally connected at the pin-and-hole place by split pin 6 with pressing mark 2; Between pressure mark 2 bottoms and support plate 5, an air bag 7 is arranged, gassy in this air bag, air bag 7 is a band tubing; Power set 4 adopt cylinder piston type, and doctor blade holder 3 is connected with cylinder 9 by lever 8.

Adopt the utility model, when the concavo-convex variation of drying cylinder face, the pressure at corresponding blade 1 place mark 2 rotates around split pin 6, thereby blade 1 is risen and fallen synchronously with the drying cylinder face under the effect of air bag 7, reaches the effect that fully sticks on the drying cylinder face.

Claims

1, a kind of scraper, it comprises blade, presses mark, doctor blade holder, power set, and wherein the blade insertion is pressed in the mark, presses mark to be connected with doctor blade holder, and doctor blade holder is connected with power set, it is characterized in that, and pressure indicates a plurality of, and does not contact mutually; Press mark and doctor blade holder to be rotationally connected, pressing between mark and the doctor blade holder has an air bag.

2, scraper according to claim 1, it is characterized in that, one support plate of fixedlying connected with doctor blade holder is arranged, a plurality of continuously arranged connecting plates are arranged at support plate top, this connecting plate is provided with pin-and-hole, the pressure mark place corresponding with the connecting plate pin-and-hole is provided with corresponding pressure mark pin-and-hole, and support plate is rotationally connected at the pin-and-hole place by split pin with pressing mark.
