Description

Blade dismounting clamp

Technical Field

The utility model relates to a blade dismouting appurtenance field, concretely relates to blade dismouting anchor clamps.

Background

The paper machine net part roller and the drying part drying cylinder are both provided with independent scrapers for scraping attachments on the surfaces of the roller body and the drying cylinder, so that the surface is kept clean, and the paper forming quality and the equipment operation are facilitated. During normal production, the scraper is in a loading closed state, and the scraper is closed and loaded to scrape attachments on the surface of the cylinder body. The length of the scraper blade is different along with the difference of the width of the paper machine and the width of the roller body, the scraper blade is generally consistent with the width of the roller body, carbon fibers and polymer composite materials are used as the materials of the scraper blade, and the scraper blade is good in flexibility and bendable. The scraper blade needs to be changed when processing the paper of different specifications or when the scraper loss is too big and regular change maintenance process, and this type of scraper length generally is more than 1 meter, and weight is heavier, mainly dismantle the back by the workman and change at present, not only waste time and energy, and need many people to cooperate, the cost of labor is high, and simultaneously, wide paper machine scraper is longer, when many people cooperate to hold in the palm the blade installation, lift the condition that unsmooth scraper blade and sword groove take place the dislocation easily, the installation accuracy is not enough, and, need hold in the palm the flat linearity with the scraper when taking out and take out, the groove can take place to take off the scraper and the slope of anchor clamps lip groove level, cause production and incident, the security is not good.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, chinese patent document discloses a support frame [ CN201920640773.4] for replacement of a scraper of a paper machine, which includes a base, a support frame provided on the base, a scraper placing plate fixed on the support frame, a dovetail-shaped sliding groove fixed on a bottom surface of the scraper placing plate, a scraper support frame provided on a bottom surface of the scraper placing plate, a dovetail-shaped slider fixed on a center of a top surface of the scraper support frame, a ball screw provided in the dovetail-shaped sliding groove, a driving motor fixed on a side portion of the scraper support frame, the dovetail-shaped slider screwed on the ball screw, vertical circular holes provided at both ends of the scraper support frame, two clamping blocks provided on a bottom surface of the scraper support frame, a winding motor fixed on a top surface of the scraper support frame, a scraper placing groove provided on a bottom surface of the clamping block, and a locking screw fixed on a side portion of the clamping block.

Above-mentioned scheme has solved the scraper dismouting inefficiency and the high problem of cost of labor of paper grade (stock) among the prior art to a certain extent, but this scheme still has a great deal of not enough, for example: dislocation easily occurs during installation, the accuracy is low, and in addition, the groove easily takes place to take off when taking out the scraper blade, causes production and incident, and the security is not good.
