Dual-frequency speed-control pelletizer

Abstract

The invention discloses a pelletizer, and aims to provide a dual-frequency speed-control pelletizer. The key points of the technical scheme are that the dual-frequency speed-control pelletizer comprises a pelletizer main body; a cutting mechanism and a feeding mechanism are sequentially mounted on the pelletizer main body; and the feeding mechanism is used for transporting plastic raw material into the cutting mechanism. The dual-frequency speed-control pelletizer is characterized in that the feeding mechanism comprises a power roller and a pressure roller clung to the outer surface of the power roller; the cutting mechanism comprises a rotary cutter component rotationally connected with the pelletizer main body and used for cutting the plastic raw material; power parts which are respectively used for driving the power roller and the rotary cutter component to rotate, and a control part are arranged on the pelletizer main body; and the control part is used for controlling the rotation speeds of the power parts used for driving the power roller and the rotary cutter component 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
