Description

Material box device capable of arbitrarily changing coating width Technical Field The invention belongs to the technical field of material boxes, and particularly relates to a material box device capable of randomly changing coating width. Background The material box is a device which is commonly used in industries such as paper making, printing, diaphragm manufacturing and the like and provides stable and adjustable flow for coating operation, the working principle is that a solution to be coated in stirring equipment is pumped to the material box by a pump, the flow can be adjusted by adjusting the rotating speed of the pump, and the material box can be divided into a plurality of combination modes of upper liquid inlet, lower liquid inlet, upper liquid outlet and lower liquid outlet due to different coating modes. In order to ensure that the solution is uniform when the solution is fed into the material box, the fluctuation of the liquid level is avoided, so that the conditions of uneven coating, missing coating and the like are caused, and the common material box adopts a structure with uniformly distributed multiple liquid feeding pipes. However, most of the current material boxes adopt fixed breadth, namely the breadth is customized according to the requirement, and taking the lithium battery diaphragm industry as an example, the domestic existing coating mode basically adopts two main modes of roller coating and spraying, and the coating material boxes basically have no influence on the whole coating effect under the condition of the fixed breadth in the existing two modes, so the material boxes are basically not changed greatly. However, with the improvement of product requirements and coating modes, the fixed-width material box is more and more difficult to meet the requirements. For example, some products require white at two ends, white in the middle and zebra stripes, and for example, a novel diaphragm coating mode is also adopted, namely, a plate roller is added after an anilox roller compared with the traditional roller coating due to the uniqueness of the point coating mode, the anilox roller also changes the effect of the anilox roller from original coating into transferring slurry, and the plate roller can not enable a milky coating head with the slurry to directly contact with a back roller during the coating operation, so that only a scheme that the width of a base film is larger than that of the plate roller can be adopted at present, and if the base film is required to be saved, only the plate roller with different widths can be customized according to the product. Disclosure of Invention In view of the shortcomings of the prior art, the invention aims to provide a cartridge device with a coating width capable of being changed at will, which can be used for coating base films with different widths. The aim of the invention is achieved by the following technical scheme. A material box device capable of changing coating width at will comprises a material box and a sliding rail, wherein a structure which is sunken towards the inside of the material box is formed on the right side surface of the material box, a bin is arranged at the sunken position, an anilox roller is horizontally arranged, the axial direction of the anilox roller is parallel to the length direction of the material box, the left part of the anilox roller is positioned in the bin and is used for being contacted with the slurry in the bin, an upper scraper is fixedly arranged outside the material box above the anilox roller, a lower scraper is fixedly arranged outside the material box below the anilox roller, the upper scraper and the lower scraper are used for scraping the slurry outside ink holes on the anilox roller, the length direction of the sliding rail is parallel to the length direction of the material box, the sliding rail is fixedly arranged in the material box, at least one sliding block is connected with the left side surface of the bin, the length direction of the second strip-shaped opening is parallel to the length direction of the material box, an upper scraper is fixedly arranged on each sliding block, a liquid inlet pipe is fixedly arranged at the left side surface of the sliding block, the upper scraper is fixedly connected with the left side surface of the material box, the sealing member is arranged at one side of the sealing member, and the left side of the sealing member is positioned at one side of the sealing member and is opposite to the left side of the sealing member. In the above technical scheme, the top end of the liquid inlet pipe is contacted with the edge of the second strip-shaped opening, and a gap is formed between the bottom end of the liquid inlet pipe and the edge of the second strip-shaped opening, so that redundant slurry in the storage bin overflows from the gap into the slurry box. In the above technical scheme, a baffle is fixedly arranged in the slurry box on the right side of
