Problems solved by technology

[0003] However, it is difficult to ensure the mobility of the doctor blade relative to the support, because of the high costs involved in cleaning the support or the doctor blade located in the support together with its guide
Especially if only a narrow margin of error is designed on the slide for the movement of the scraper relative to the support, this makes the slide relatively sensitive to contamination
This can cause the scraper to get jammed, for example

Embodiment Construction

[0035] in such as Figure 1 to Figure 3 In the illustrated embodiment of the doctor blade holder, the doctor blade holder is shown in the closed state on the left side of the figure and the doctor blade holder is shown in the open state on the right side of the figure, respectively. In addition, components with the same function are denoted by the same reference numerals in all the figures.

[0036] like figure 1 The doctor block shown has a carrier 1 on which a stationary holding clip 2 is arranged. The support 1 is, for example, a beam extending across the width of the material web to be coated in the transverse direction of a coating device (not shown), on which a doctor element 6 is mounted. exist figure 1 The scraper element is shown as scraper blade 6 in FIG.

[0037] The stationary holding clip 2 has a clamping part 21 and a guide part 22, the guide part 22 has a guide, which engages with the doctor element 6 when the doctor element 6 is clamped, and with respect to...

Abstract

The present invention relates to a squeegee holder, in particular to a coating apparatus for coating materials such as paper or paperboard. The squeegee holder is provided with a plurality of keeping clamping sheets, a squeegee component can be kept among the keeping clamping sheets, the keeping clamping sheets can mutually guide through at least one flexible component and can move relative to each other under the condition that at least one flexible component deforms. The flexible component can be a spring component or a soft bendable component capable of deforming under the condition of not having a recovery force. At least one operating component can be preferably arranged, and the keeping clamping sheets can move relative to each other through the operating component.

Description

technical field [0001] The invention relates to a doctor frame, in particular in a coating device for coating material webs, with which a doctor element can be held releasably. Background technique [0002] The doctor holders known from the prior art have a slide that is movable on a support and has a holding clip that interacts with a stationary or fixed holding clip mounted on the support. The doctor blade holder is forcibly exposed to and contaminated by the coating color. According to the prior art, an outlet is provided on the doctor blade and / or the supporting member, and when the doctor blade holder is cleaned, the coating paint or cleaning agent can flow out from the outlet. [0003] However, it is difficult to ensure the displaceability of the scraper relative to the carrier, since a high level of effort is required for cleaning the carrier or the scraper located in the carrier together with its guide. In particular, if only a narrow margin of error is provided on...
