Description

Technical Field

[0001] The utility model belongs to the technical field of granulating units, and in particular relates to a banburying single-screw granulating unit. Background Art

[0002] IXPP is the abbreviation of irradiated cross-linked polypropylene foam material. It is a new type of polymer foam material developed in recent years. It can be widely used in automotive interior, aerospace, ship machinery, sports and leisure industries. The main components of the internal mixing single screw granulator include feeding device, internal mixing chamber and screw. The working principle is based on changing the physical and chemical properties of the material to achieve the mixing, melting, chemical reaction and other operations of the material. The material first enters the internal mixing chamber through the feeding device. In the internal mixing chamber, the material is subjected to high temperature and high pressure to melt and mix. Subsequently, the molten material enters the screw. The spiral shape and rotational motion of the screw cause it to rub and mix with the material, while pushing the material forward. In the process of moving forward, the temperature and pressure of the material gradually decrease, causing it to solidify and form particles.

[0003] The common internal mixing single screw granulator has a relatively simple structure, which makes it difficult to quickly cool down the extruded material particles. At this time, the material particles have a certain viscosity and are easy to adhere to the surface of the equipment during transportation, which increases the difficulty of cleaning. At the same time, it will also increase the loss of production materials and increase production costs. Utility Model Content

[0004] The utility model aims to provide a single-screw mixing granulator unit to solve the technical problems of inconvenience in rapid cooling and large loss of production materials, so as to achieve the purpose of rapid cooling, reduced cleaning difficulty and reduced production cost.

[0008] Furthermore, the motor is fixedly connected to the fixing seat, and the output end of the motor is fixedly connected to the screw rod.

[0009] Furthermore, the delivery pipe is fixedly connected to the fixing seat, and the screw rod is adapted to the delivery pipe.

The rotation of the motor 202 can drive the screw 204 to rotate, so as to rub and mix the material melted by the internal mixer 1, and at the same time push the material to form particles through the leakage hole 206. The conveying pipe 203 is fixedly connected to the fixed seat 201, and the screw 204 is adapted to the conveying pipe 203. The fixed connection between the conveying pipe 203 and the fixed seat 201 can make the conveying pipe 203 more firm and improve the stability of use.
