Description

DOUBLE AND TAPER SCREW COMPOUND EXTRUDER
Technical Field
The invention relates to an extruder which improves the production quality and speed by providing the removal of the heat that is generated with friction by increasing the advancing ratio of the compound melt in the space between the screw and the barrel without affecting the physical, mechanical and chemical properties of the product.
State of the Art
Today, extruders can be used in all processes where the plastic raw material needs to be melted.
An extruder is a machine which brings the plastic material to the melting heat under heat and high pressure and renders the same a usable raw material.
The structure of the extruder simply consists of an actuating motor and a screw barrel mechanism. Thanks to the helical screw grooves on the screw piece, it moves the raw material as it rotates. In this process, it provides for the melting and pressure increase.
Extruders are divided into classes among themselves such as double- screw and planet extruders. Additionally, the extruder screw design displays differences based on the raw material to be manufactured.
Plastic extrusion is a high-volume production process wherein war plastic is melted and shaped in a continuous profile. With extrusion, pipes, hoses, plastic wicks, fences, window profiles, thermoplastic coatings and cable insulation products are manufactured.
The compound is the product obtained by adding additive and filling materials into the raw materials whose carrier consists of polymers to improve its mechanical properties, heat resistance, chemical resistance, electrical and heat insulation, dimensional stability, fire resistance, etc. The additives and fillers to be used for each property that is wished to be improved change, as well as their ratios in the composition. Depending on these changes, the production processes differ as well.
The most important one of the production parameters is the distribution of the components within the mixture. There are two factors as mixing and kneading, which provide for the correct distribution, and the product which is exposed to these factors starts to lose its properties during production. The limiting factors caused the variation of the compound machines and machines that have different operating systems to produce different products.
The constant increase in oil prices today triggers the raw material price increase in the plastics sector in the same way. Hundreds and thousands of different properties are required from the main plastic materials which have specific properties and a totaling number of 20 in the best case. The only method to provide this diversification lies within compounding. For example; combustible plastic can become fireproof, the prices can be lowered, they can be more resistant to sunlight, and improving the various endurance values such as the impact, pull, and elongation is possible with compounding.
With compounding, especially thermoplastic materials and new materials whose binding is provided by mixing thermal treatment and pressurized are developed. The machine required for compounding is the double screw extruder which rotates in the same direction. With this machine, it is possible to produce less expensive materials with new properties. For example; it is possible to manufacture fireproof composite sheets for aluminum facade sidings. It is possible to manufacture sheets directly with the fireproof additive being mixed into the carrier. In the same way, it is possible to make both compound and film with the double screw extruder in the film extrusion used in the production of bags. Additionally, it is possible to manufacture more profitable products by formulating the ingredients correctly.
The utility model application titled “Melt Filter Used in the Production of Plastic Pipes” application number 2019/01129 ‘relates to a melt filter (A) which is positioned in the extruder machines that perform plastic pipe production and prevents the material quality from being impaired by holding the contaminated microscopic particles within the melted plastic coming from the extruder and other foreign materials that can harm the pipe head unit. ’ The utility model application mentioned above is related to the extruder machine used in the production of pipes, and it is different from the said invention with its melt filter feature which prevents the quality of the material from being impaired.
The patent application titled “Single Outlet Multiple Profile or Pipe Production Method” application number 2017/08685 ‘relates to the production method of single-outlet multiple profiles or pipe production in extruder machines. In the invention, the raw material given to the extruder machine (1) leaves the product mold (3) as multiple and single piece profile (4) or pipe (5) and the profile (4) or pipe (5) is sliced or cut from the point of the junction by means of a cutting tool (6) and thus separated.’
The said invention relates to the multiple profiles or pipe production from a single outlet, and is different from the said invention.
The Object of the Invention
The invention improves the production quality and speed by providing the removal of the heat that is generated with friction by increasing the advancing ratio of the compound melt in the space between the screw and the barrel without affecting the physical, mechanical and chemical properties of the product.

Description of the Invention
During compound production, screws are commonly used for the transfer of manufactured compound as melt, passing of the same through a perforated plate by creating pressure, and cutting by means of a rotational blade placed at the front side of the perforated plate. The screw and transfer systems used show similarities with each other, and they differ depending on the ratio of the compound within the product, the production speed, and the shape, geometry, size and temperature control method that are different based on the physical and chemical properties of the compounds.
The system consists of a long screw (2) and short screw (1) placed within the barrel (8) and driven by a reducer (7) that has a double outlet connected to one electric motor (6). It consists of the taper screw (3) placed at the front of the long screw (2) and the temperature control system (5) placed within the long screw (2). The rotational direction of the screw can be changed to rotate in the same or opposite direction depending on the mechanical, physical, and chemical properties and requirements of the products to be manufactured.
To provide the mixing and kneading effect of the products to be produced by using the invention and manufacture products that have different requirements, the long screw (2) and taper screw (3) are moved forward and backward in the axial direction and the pressure and kneading effect to affect the product is changed, and the product range is increased. The profiles of the screws are designed in a way to allow the forward and backward movement.
The mixture in the form of dust, granules or melt is fed to the system by means of the feeding orifice (4) which is located near the reducer (7) side of the long screw (2) and short screw (1) that operate simultaneously.
Short screw (1) and long screw (2) provide for the advancement of the materials in the space between the screws and barrel, as well as pressurizing. Thanks to the pockets (9) on the channel or channels placed helically on the taper screw (3) in front of the long screw (2) near the material exit, the materials that have melted and that are already melted are kneaded and compressed as they advance. When the design of the taper screw (3) is compared with the traditional screw structures of the melt materials, they advance to a longer distance and they are repeatedly kneaded by filling the pockets (9) in and out as they advance. Thereby, the same kneading and mixing effect is provided with a much shorter screw in total length, compared to the traditional screws.
