Coater scraper apparatus

Abstract

The invention relates to a coater scraper apparatus. The apparatus comprises a scraper rack connected to a coater frame, a scarper having a cutting edge corresponding the coating roller of a coater is press-fitted on the scraper rack through a scraper press plate, a scraper rack adjusting shaft paralleling to the scraper rack is movably arranged on the coater frame in a penetrating mode, the scraper rack is connected with the scraper rack adjusting shaft and rotate around the scraper rack adjusting shaft, an adjusting worm gear is fixedly connected with the scraper rack adjusting shaft in a penetrating mode, the coater frame supports an adjusting worm having a driving cooperation with the adjusting worm gear, and the adjusting worm is connected with a hand wheel. The coater scraper apparatus accurately controls the adjustment between the scraper and the coating roller by adopting the scraper rack rotatablely far from or close to the coating roller and combining the scraper adjusting seat and a trimming cylinder, so the apparatus has the advantages of simple and compact structure, convenient and accurate adjustment, and effective ensure of the thickness of a glue solution on the coating roller for the uniform adjustment, and is suitable for the use of various different specification coating rollers and coating thicknesses.

Description

technical field [0001] The invention relates to the field of coater equipment, in particular to a scraper device used for scraping glue by a coater. Background technique [0002] Coating machine is a kind of equipment that paints a layer of glue, paint or ink with specific functions on the rolled film material. After the film material is painted, it needs to be dried and rolled up. The thickness of the coating machine glue is usually controlled by the scraper corresponding to the glue roller, which is the guarantee of the uniform glue coating of the coater, and the gap between the scraper and the glue roller directly determines the coating thickness of the glue solution. When different coating thicknesses are required, it is usually necessary to adjust the gap between the scraper and the glue roller. In the prior art, for example, the patent No. 201020650477.1 discloses a scraper adjustment device for a coating machine. The slideway groove slides up and down relative to the...

Problems solved by technology

In the prior art, for example, the patent No. 201020650477.1 discloses a scraper adjustment device for a coating machine. The slideway groove slides up and down relative to the sliding frame through the upper and lower top wires, and the sliding frame and the scraper groove slide back and forth relative to the scraper frame through the front and rear top wires. In order to achieve the purpose of adjusting the gap and relative position between the scraper and the roller, but its disadvantage is that the edge of the scraper is always tilted upward, and when the scraper scrapes off the excess thickness of the glue on the roller, the glue flows along the scraper. The adjustment device will be blocked in the adjustment device, which will affect the normal adjustment and use; the relative position and angle between the support frame and the scraper are fixed. When changing the rollers of different specifications, the up and down, front and back position adjustment of the scraper has the problem that it cannot correspond to the roller, and the applicability is poor. ;The position adjustment of the scraper is completely adjusted by the top wire. During manual operation, the operation sequence of the top, bottom, front and rear top wires has different effects on the error of the gap between the scraper and the roller. The adjustment accuracy of the gap between the scraper and the roller is low, which is not conducive to improving the coating Adhesive thickness control, final coating product quality is not stable
