Technical Field

The application relates to a scraper clamp, in particular to a scraper clamp for a lifting base cylinder.

Background

In the production process of the paper industry, a roller is used, and a scraper device is widely applied equipment. If foreign materials, paper lint, etc. are attached to the surface of the roll of the paper machine, they are removed by a doctor blade. A typical doctor apparatus has a full width doctor blade mounted on the outer circumferential surface (in the axial direction) of a roll. The edge of the doctor blade is pressed against the outer circumferential surface of the roll by a suitable pressure to remove foreign matter and the like on the outer circumferential surface. The scraper is fixed by a special clamp. The foreign matter that raises the base cylinder surface need use great line pressure to remove, arouses the vibration of scraper blade easily, and in addition, the scraper blade belongs to the consumable article, and the scraper blade after wearing and tearing can not reuse, has aggravated manufacturing cost's input. Accordingly, improvements are needed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 and 2, a scraper clamp for a lifting cylinder, including a scraper clamp fixed on a scraper frame 1 and a scraper blade 2 installed in the scraper clamp, the scraper clamp includes a rotating shaft 3 fixed on the scraper frame 1 and a plurality of finger-shaped clamping blocks 4 rotatably arranged on the rotating shaft 3, one end of each finger-shaped clamping block 4 far away from the scraper frame 1 is convexly provided with an upper pressing block 41 and a lower pressing block 42, the upper pressing block, the lower pressing block and the finger-shaped clamping blocks are integrally formed, a clamping opening for placing the scraper blade 2 is formed between the upper pressing block 41 and the lower pressing block 42, a plurality of stepped grooves 43 are processed in the clamping opening, pluggable pad cutter strips 44 are arranged in the stepped grooves 43, the tail end of the scraper blade 2 abuts against the pad cutter strips 44, and an air bag 5 is arranged between one end of the finger-shaped clamping block 4 deviating from the clamping opening and the scraper frame.

Among this technical scheme, scrape knife rest and scraper blade and belong to prior art, have not been repeated for one's sake of difference here, this scraper anchor clamps simple structure, offset the pressure deviation of the whole width of cloth line that the cylinder pressurization arouses through the gasbag, scraper blade and roll surface flexible contact have good following nature, can steadily corrugate the scraper function under the condition of very high line pressure, the scraper of the applicable different broad width in ladder groove, scraper blade after the wearing and tearing can grind the back, the position through adjustment pad sword strip is reused, and production cost is reduced.

Further, the side of the end of the scraper holder 1 near the scraper blade 2 is provided with a mounting groove, and the rotating shaft 3 is fixed in the mounting groove through a shaft collar 6.

Among this technical scheme, the fixed knot of collar and pivot constructs to belong to conventional structure, and the equidistant interval of finger-shaped clamp splice sets up in the pivot, and can revolute the pivot and scrape the knife rest rotation relatively for the horizontal different positions of scraper blade can be along with the fluctuation on dryer surface, hug closely dryer surface with invariable pressure, thereby improve pincher trees rate and cleaning efficiency.

Furthermore, a limiting boss 45 arranged corresponding to the air bag 5 protrudes from the side surface of one end of the finger-shaped clamping block 4, which is far away from the clamping opening.

In the technical scheme, the limiting boss is used for limiting the position of the air bag, and the air bag is prevented from sliding out of the position between the finger-shaped clamping block and the scraper frame.

Further, the side of the finger grip 4 facing away from the doctor holder 1 is provided with an ash baffle 7.

In the technical scheme, the bad results caused by the fact that external foreign matters fall between the finger-shaped clamping blocks to influence the rotation of the finger-shaped clamping blocks and the like are avoided.

Furthermore, the ash blocking plate 7 is bent to form a clamping portion 71 at one end close to the upper pressing block 41, and the end portion of the upper pressing block 41 is clamped in the clamping portion 71.

In the technical scheme, the ash blocking plate is integrally formed by bending a metal thin plate, a certain deformation amount is allowed, different transverse parts of the scraper blade cannot interfere with the fluctuation of the surface of the drying cylinder, and in order to enhance the fixing strength of the ash blocking plate, the ash blocking plate can be additionally fixed on the corresponding finger-shaped clamping blocks by screws.

Further, two ends of the scraper frame 1 are respectively provided with an adjusting bolt 8, and the adjusting bolts 8 are respectively connected to the corresponding finger-shaped clamping blocks 4.

In the technical scheme, through holes corresponding to the adjusting screws are formed in the two finger-shaped clamping blocks at the end parts, and the adjusting bolts are matched with the nuts, so that the finger-shaped clamping blocks are kept in a range relative to the movement of the scraper frame, namely, the force of the scraper blade on the base lifting cylinder is kept in a limited range.

In conclusion, the scraper fixture for the lifting base cylinder is simple in structure, the pressure deviation of the whole width line caused by the pressurization of the air cylinder is offset through the air bag, the scraper blade is in flexible contact with the roll surface, the scraper fixture has good follow-up performance, the function of a wrinkling scraper can be stably carried out under the condition of very high line pressure, the stepped groove is suitable for scrapers with different widths, the abraded scraper blade can be reused after being ground, and the production cost is reduced.
