Description

Technical Field

[0001] The present application relates to the technical field of masterbatch processing, and in particular to a screening device for masterbatch processing. Background Art

[0002] Masterbatch is a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins that are well dispersed. Masterbatch is generally composed of three basic elements: pigments or dyes, resin carriers and additives. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material.

[0003] Traditional masterbatch processing requires that various materials be mixed evenly first, and then extrusion is performed. The extruded finished product needs to be pelletized. In order to ensure the consistency of the finished product particles, a screening device is usually added after the pelletizing operation to screen the cut masterbatch and remove unqualified finished products. Currently, the most commonly used is the linear vibrating screen. The linear vibrating screen uses the principle of vibration motor excitation. The two motors move synchronously in opposite directions, so that the material is thrown up on the screen surface and moves forward in a jumping straight line, so as to reasonably match the screen to achieve the purpose of screening.

[0004] Most of the linear vibrating screens in the prior art are open structures, which leads to flying dust during the screening process and affects the use; there is also a linear vibrating screen with a cover plate in the prior art, such as a Chinese patent with authorization announcement number CN208894584U and publication date of May 24, 2019, which discloses a linear vibrating screen, including a base frame and a screen box, the screen box and the base frame are connected by at least four springs, a vibration motor is provided at the bottom of the screen box, a screen plate is provided in the screen box to divide the screen box into an upper cavity and a lower cavity, and screen holes are provided on the screen plate. The upper end of the screen box is detachably connected with a cover plate, and the front end of the cover plate is provided with a hopper for adding materials to the upper cavity. The tail of the screen box is provided with a first discharge hopper connected to the upper cavity for receiving materials that have not passed through the screen plate, and the tail of the screen box is also provided with a second discharge hopper connected to the lower cavity for receiving materials that have passed through the screen plate. A plurality of buckle hooks are provided on both sides of the cover plate, and a latch-type quick clamp corresponding to the buckle hooks is provided on the side of the screen box to fix the cover plate on the screen box.

[0005] In the above application, a cover plate is provided on the screen box to reduce dust generated during operation, and a hook and a latch-type quick clamp are used to quickly fix the screen box. However, the inventor believes that the fixing in the application is a clamp and hook structure, which cannot be adjusted. After long-term use, the connection may become loose and cannot be fixed, thus affecting the use effect. Utility Model Content
