Problems solved by technology

The aforementioned vibratory screening equipment has the advantage of high screening efficiency, but relatively large noise will be generated during the entire vibratory screening process, which will affect the production and working environment. The thermoplastic particles in the net are easily affected by vibration, and the thermoplastic particles are prone to collision and friction with each other, thereby reducing the screening quality

Abstract

The invention discloses a roller type screening device of thermoplastic plastic particles. In the structure of the roller type screening device, a screening roller assembly is additionally arranged in an opening in the top of an equipment body, and the screening roller assembly is mainly composed of a pair of mounting cross arms and at least two screening rollers located between the pair of mounting cross arms; the roller faces of every two adjacent screening rollers keep tangent; inclined tangent plates are arranged on the other pair of side walls of the equipment body, and the lower edges of the tangent plates and the roller faces of the screening rollers corresponding to the tangent plates keep tangent; the one or more screening rollers spaced each phase in the screening roller assembly are subjected to transmission through a transmission assembly; a power mechanism driving screening roller sets corresponding to the transmission assembly to rotate in the same direction is arranged on the transmission assembly; and the rotating directions of every two adjacent screening rollers are opposite. The roller type screening device achieves the technical aim of preventing noise from being generated in the screening process of the thermoplastic plastic particles different in particle size, and the work environment of enterprise production workshops can be improved; and meanwhile a good screening effect is achieved on the thermoplastic plastic particles different in particle size.

Description

technical field [0001] The invention relates to a screening device for thermoplastic plastic particles, in particular to a roller type screening device for thermoplastic plastic particles. Background technique [0002] Thermoplastics are generally polymerized from monomers that use petroleum as raw materials. The polymerized product is generally powder. Powder is not convenient for storage and transportation, and it is also inconvenient to process and shape. Generally, thermoplastic pellets are prepared by extruder granulation. The granulation process generally adds additives such as antioxidants to increase the storage time of the raw materials and give the materials other functions. [0003] At present, the screening of thermoplastic particles generally uses a vibrating screen with sieve holes. The vibrating screen is set on the frame, and the frame-shaped screen is driven by a geared motor to vibrate, so as to realize the screening of thermoplastic particles of different ...
