Automatic mixing device for polyester chips

Abstract

The invention discloses an automatic mixing device for polyester chips, and relates to the technical field of stirring, and particularly relates to an automatic mixing device for polyester chips. Theautomatic mixing device comprises a stirring box, wherein the upper surface of the stirring box is fixedly connected with a protective box; the upper surface of the protective box is fixedly connectedwith a support frame; the interior of the support frame is fixedly connected with a motor; the lower end of an output shaft of the motor is fixedly connected with a first rotary shaft; the outer surface of the first rotary shaft is rotationally connected with a fixed sleeve; and the outer surface of the fixed sleeve is fixedly connected with a connecting plate. The automatic mixing device for thepolyester chips has the advantages that by arranging an electric telescopic rod, a gear sleeve, a first gear, a second gear, a third gear and a fourth gear in a matching way, the gear sleeve can be pulled by the extending and retracting of the electric telescopic rod in the use process, so as to change the matching of different gears, change the rotation speed of the stirring rod, and reach the purpose of uniform stirring.

Description

technical field [0001] The invention relates to the technical field of mixing, in particular to an automatic mixing device for polyester chips. Background technique [0002] Polyester chips usually refer to the polyester raw materials obtained by polymerization, which are generally processed into flake particles of about 4*5*2 mm. The process routes of polyester production include direct esterification method (PTA method) and transesterification method (DMT method). The PTA method has the advantages of low raw material consumption and short reaction time, and has become the main process and preferred technical route of polyester since the 1980s. The large-scale production line is a continuous production process, while the semi-continuous and batch production process is suitable for various small and medium-sized production devices. The uses of polyester now include fibers, various containers, packaging materials, films, films, engineering plastics and other fields. [000...

AI Technical Summary

Problems solved by technology

[0003] Polyester chips often need to be mixed with different types before they can be used better. However, the existing polyester chip mixing devices are often not stirred evenly during use, which affects the use effect of the polyester chip mixture. At the same time, the existing mixing devices are generally fixed, which is very inconvenient when moving. The existing automatic mixing devices for polyester chips have problems such as uneven mixing and inconvenient movement.
