Problems solved by technology

[0003] The object of the present invention is to provide a kind of equipment for producing modified polypropylene chopped engineering fiber, in order to solve the problem that in the chopping process, generally the two ends of the fiber are clamped first, and then the fiber is cut by the rapid movement of the cutter. , the tensile stress at both ends is large when clamping, and the stress is released after cutting, and the short fibers with double-sided incisions are broken, so that the silk threads are scattered on the conveyor belt. Flying technical issues in the environment

Abstract

The invention discloses a device for producing modified polypropylene chopped engineering fibers. The signal end of the box and the signal end of the electric control box are electrically connected, the motor is controlled by the electric control box, and a transmission crawler is provided in the input groove. The mechanism fits on the slideway, and presses the roller along the arc surface of the slideway to contact the chopped fibers on the output crawler belt. Because the slideway has the function of height adjustment between the arc surface and the horizontal surface, the gap between the roller wheel and the monofilament fiber can be reduced. The distance between the rollers makes the chopped engineering fibers evenly disperse on the output crawler when the pressing roller advances obliquely, reducing the dispersing process when the engineering fibers are mixed with concrete in the later stage, and the pressing plate is pressed on the dispersed fibers. , so that the output crawler will not fly in the working environment when the monofilament fiber is sent out.

Description

technical field [0001] The invention relates to the technical field of engineering fiber production, in particular to a device for producing modified polypropylene chopped engineering fibers. Background technique [0002] Polypropylene fiber is also referred to as PP fiber, polypropylene fiber, and is also called concrete and mortar crack-resistant synthetic fiber in engineering. The polypropylene fiber that improves the performance of concrete mainly includes bundled monofilament polypropylene fiber and mesh polypropylene fiber. There are two kinds of fibers, the length of these two kinds of polypropylene fibers is 6-50mm, due to their different shapes and deniers, the tensile strength they can withstand is quite different, and other physical properties are basically the same. The polypropylene raw materials used to produce fibers It is a regular crystalline polymer, which is a milky white, odorless, tasteless, non-toxic thermoplastic. The bundled monofilament polypropylene...
