Description

Masterbatch vibration screening device for shrink film production Technical Field The utility model relates to the technical field of masterbatch screening of shrink films, in particular to a masterbatch vibration screening device for shrink film production. Background The shrink film is mainly used for packaging products with regular and irregular shapes, is nontoxic and environment-friendly, has high transparency, high shrinkage performance and good heat sealing performance, and is widely applied to the processing fields of automobile products, plastic products, stationery, books, circuit boards and the like. The processing technology of the shrink film generally comprises the steps of mixing materials in an internal mixer, manufacturing master batches by a granulator, vibrating and screening the master batches, extruding sheets, foaming and the like, wherein the purpose of the master batch vibrating and screening technology is to screen out larger and smaller master batch particles, so that master batches with approximately the same particle size are obtained. At present, the most used in the masterbatch screening process is the linear vibrating screen, and during operation, the masterbatch is poured to the higher side of the vibrating screen through one side of the vibrating screen, and the masterbatch vibrates under the action of a vibrating motor, so that the masterbatch moves to the lower side of the vibrating screen. In order to make the master batch move along the middle as far as possible and ensure that the master batch moves stably, the vibrating motor is usually arranged on the symmetry axis of the vibrating screen, namely, arranged at the center of the width direction, so that the vibration amplitude of the center position is larger on the screen surface structure of the linear vibrating screen, the vibration effect is stronger, and at the moment, the master batch close to the periphery of the symmetry axis of the linear vibrating screen is more subjected to the vibration effect, and is easier to be thrown up to move forwards. In contrast, the vibration amplitude of the screen surface edge position is smaller, the vibration effect is relatively weaker, and the material moving speed at the edge is slower. Meanwhile, the through holes formed in the edge of the vibrating screen surface can further prevent the master batch from moving forwards. Due to the two reasons, the situation that the material is accumulated due to unsmooth movement of the master batch tends to occur at the edge of the linear vibrating screen, and the screening efficiency of the master batch is seriously affected. In addition, because the master batch is piled up, the master batch at the edge needs to be manually cleaned in time, and the labor intensity is greatly increased. Disclosure of utility model The utility model aims to solve the technical problems in the prior art and provides a masterbatch vibration screening device for producing a shrink film, which can prevent masterbatch accumulation at the edge of a vibrating screen and reduce labor intensity.
