A double frequency conversion speed regulation granulator

Abstract

The invention discloses a granulator and aims to provide a double frequency conversion speed regulation granulator. The key points of the technical solution are: comprising a main body of the granulator, on which a material cutting mechanism, a It is a feeding mechanism for transporting plastic raw materials into the material cutting mechanism, and is characterized in that: the feeding mechanism includes a power roller and a pressure roller that is attached to the outer surface of the power roller, and the material cutting mechanism includes a granulator The main body is connected in rotation and is used to cut the rotary cutter assembly of plastic raw materials. The main body of the granulator is also equipped with a power part and a control part for driving the power roller and the rotary cutter assembly to rotate respectively. The control part uses It is used to control the rotation speed of the power part that drives the power roller and the rotary cutter assembly to rotate.

Description

technical field [0001] The present invention relates to a granulator, more specifically, it relates to a granulator capable of realizing double frequency conversion speed regulation. Background technique [0002] The transmission line is a line-shaped device that transmits electromagnetic energy. It is an important part of the telecommunication system. It is used to transport the electromagnetic waves carrying information from one point to another along the route specified by the transmission line. It has been widely used in people's production, In various fields of life, the transmission line mainly includes wires and outer cladding used to transmit electric energy and signals inside. The material of the outer cladding is usually made of plastic, and the raw material for producing the plastic outer cladding is granular plastic raw material. [0003] The machine that produces the plastic outer cladding from the granular plastic raw material usually adopts a plastic extruder,...

Problems solved by technology

[0004] In addition, once it is used to produce the outer cladding of precision wires such as missile signal transmission lines, the large plastic extruder cannot be used because the wire diameter of the missile signal transmission line is small, and the extrusion of the plastic extruder The output screw will also be relatively small, which will lead to the following problems: firstly, it is difficult for the small screw to convey the plastic raw material with large particles; secondly, the plastic raw material with large particles can only be melted at a higher temperature, even at It cannot be guaranteed to be in a completely molten state at a temperature of 380°, which does not meet the requirements of environmental protection and energy saving; the solution to the above problems is usually to reduce the volume of traditional plastic raw material particles, so that it can be applied to the production of special transmission lines

[0005] The raw materials used for the above-mentioned large and small plastic raw materials are similar, but due to their different sizes, it will directly cause the manufacturers of their plastic raw materials to set up multiple processing equipment for processing. The shape of the plastic raw materials is basically For elongated shape, the processing equipment generally adopts a granulator, and the plastic raw material is cut into granular raw materials by the granulator, such as a Chinese patent granulator with application number 201280048273.2, which includes a cutting device, the cutting device is driven by a driving device, wherein the driving device is housed in a pelletizer housing, and the cutting device is housed in a module housing, the wood block housing is detachable Attached to and removable from the granulator housing, and wherein the cutting device is connected to the drive by a releasable connector, the cover cutting device is removable from the module housing Together as a unit, it is removed from the granulator body. The granulator with the above structure achieves the purpose of detachable module shell. However, in the actual production process, it is impossible to realize that a granulator can produce various specifications and lengths. The purpose of plastic raw material pellets
