CN203343023U - Coating defect removing device for smooth-roll coating product - Google Patents

Abstract

A coating defect removing device for a smooth-roll coating product comprises a knife rest, a metering roll and a coating roll which are all sequentially arranged, wherein a press roll is arranged above the coating roll, and a scraper and a powerful magnet are installed on the knife rest. The coating defect removing device for the smooth-roll coating product is simple in structure and easy in implementation, the powerful magnet is attracted on the knife rest to produce attractive force between the metering roll and the knife rest when the coating defect removing device is used, so that the bending deformation of the metering roll caused by the compression of the scraper is eliminated by the attractive force between the powerful magnet and the metering roll, paint is guaranteed to be uniformly and axially distributed on the coating roll, as a result, the quality defect that the middle part of a coating is thin and the two sides of the coating are thick on the coating product is overcome to improve the horizontal uniformity of the coating of the coating product, so as to improve product quality.

Description

A kind of smooth roll coated product holiday cancellation element

Technical field

The utility model belongs to smooth roll coating production equipment technical field, particularly a kind of smooth roll coated product holiday cancellation element.

Background technology

The smooth roll coating, because of the coated face excellence, is indispensable a kind of in numerous coating methods.In the smooth roll coating, the gap precision between applicator roll and metering roll is the key that guarantees the coating layer thickness precision, and surface roughness, linearity, radius run-out degree and assembly precision etc. when applicator roll and metering roll are manufactured are all closely bound up with the coating layer thickness precision.But, at the volley due to the radial pressure that is subject to scraper, metering roll can produce micro-flexural deformation to the applicator roll direction, make twice of coating intermediate thin on applicator roll thick, finally cause twice of coated product coating intermediate thin thick, affect product quality.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle and can overcome the smooth roll coated product holiday cancellation element of the thick defect in smooth roll coated product coating intermediate thin both sides.

For achieving the above object, the technical solution of the utility model is: a kind of smooth roll coated product holiday cancellation element, comprise the knife rest, metering roll and the applicator roll that set gradually, and the applicator roll top is provided with pressure roller, and scraper and strong magnets are installed on knife rest.

Described scraper is arranged on knife rest by the bolt of pressing plate and fixation clip.

Compared with prior art, the utility model has the advantages that:

1, the utility model comprises the knife rest set gradually, metering roll and applicator roll, the applicator roll top is provided with pressure roller, scraper and strong magnets are installed on knife rest, it is simple in structure, easy to implement, during use, strong magnets is pull-in on knife rest, produce gravitation between metering roll and knife rest, eliminate the flexural deformation of metering roll because produced by the scraper compressing by the gravitation between strong magnets and metering roll, guarantee that coating axial distribution on applicator roll is even, thereby the thick mass defect in coating intermediate thin both sides on the elimination coated product, to improve the horizontal uniformity of coating of coated product, thereby improve the quality of products.

2, scraper is arranged on knife rest by the bolt of pressing plate and fixation clip, is convenient to dismounting, is easy to safeguard.

The accompanying drawing explanation

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

The specific embodiment

Smooth roll coated product holiday cancellation element as shown in Figure 1, it comprises knife rest 1, metering roll 4 and the applicator roll 6 set gradually, above applicator roll 6, both sides are respectively equipped with a pressure roller 9, for adjusting the cornerite of coated product 5 and applicator roll 6.The scraper corresponding with metering roll 42 and strong magnets 3 are installed on knife rest 1, and scraper 2 is arranged on knife rest 1 by pressing plate 7 and the bolt 8 of fixation clip 7.

In the present embodiment, the installation quantity of strong magnets 3 is determined according to the bending strength of its magnetic force size and metering roll 4.

When the utility model is used, strong magnets 3 is pull-in on knife rest 1, produce gravitation between metering roll 4 and knife rest 1, eliminate the flexural deformation of metering roll 4 because produced by scraper 2 compressings by the gravitation between strong magnets 3 and metering roll 4, guarantee that coating axial distribution on applicator roll 6 is even, thereby eliminate the thick mass defect in coating intermediate thin both sides on coated product 5, to improve the horizontal uniformity of coating of coated product 5, thereby improve the quality of products.

Claims (2)

1. a smooth roll coated product holiday cancellation element, is characterized in that: comprise the knife rest, metering roll and the applicator roll that set gradually, above applicator roll, be provided with pressure roller, scraper and strong magnets are installed on knife rest.

2. smooth roll coated product holiday cancellation element as claimed in claim 1, it is characterized in that: described scraper is arranged on knife rest by the bolt of pressing plate and fixation clip.
