Description

Glass fiber feeding mechanism of screw extruder

Technical Field

The utility model relates to a fine feed mechanism of glass of screw extruder.

Background

In the plastic extrusion molding equipment, the plastic extruder is generally called a main machine, and the subsequent equipment matched with the plastic extruder is called an auxiliary machine. After the development of the plastic extruder for more than 100 years, multiple types of double screws, multiple screws and even no screws and the like are derived from the original single screw. The plastic extruder (main machine) can be matched with various plastic forming auxiliary machines for pipe material, film, bar material, monofilament, flat filament, packing belt, extruding net, plate (sheet) material, profiled bar, granulating and cable covering, etc. to form various plastic extrusion forming production lines to produce various plastic products. Therefore, the plastic extrusion molding machine is one of the machines widely used in the plastic processing industry at present or in the future. With the further development of the technology, plastic materials with overhigh strength and high toughness are needed in many fields, such as automobile chassis, but at present, many automobile chassis cannot give consideration to both of the materials, either the stretching is insufficient, the impact is insufficient, or the surface quality is not feasible.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a glass fiber feeding mechanism of a screw extruder, aiming at high glass fiber products, glass fiber feeding materials on glass fiber rolls are preheated before mixing, thus meeting the requirements of energy conservation and consumption reduction; the glass fiber feeding process is soft, the raw material glass fiber is not damaged, and impurities are not brought in the glass fiber feeding process.

In order to achieve the above object, the technical scheme of the utility model is to design a fine feed mechanism of glass of screw extruder, including setting up the fine peg of hanging that is used for in its frame of screw extruder, the fixed square box that is equipped with as the fine buffer memory of glass preheats the chamber on the side of its barrel of screw extruder. Therefore, before glass fiber is fed, the glass fiber before being fed is properly preheated by utilizing the residual temperature of the cylinder wall of the machine cylinder, the melting heat required by the glass fiber mixed with PA after entering the machine cylinder is reduced, and the consumption of heat energy is reduced.

The technical scheme is that a heat insulation guide wheel is rotationally arranged in a square box, and a glass fiber feeding port and a glass fiber discharging port are respectively arranged at two corners of a diagonal line on the square box; the square box is made of heat insulation materials and is in a square groove shape formed by five rectangular plates. The glass fiber is wound from the glass fiber finished product to the wire hanging rod and then enters the glass fiber feeding port, bypasses a plurality of heat insulation wheels of the glass fiber caching preheating cavity, and then comes out from the glass fiber discharging port until reaching the machine barrel, is heated and mixed with other raw materials such as PP or PA, and is extruded into wires by the screw extruder. Considering that the surface area of the machine barrel is increased instead by the arrangement of the protruded square box, the heat dissipation area is easily increased, and therefore the square box is made of heat insulation materials to reduce the heat dissipation.

The further technical scheme is that a flexible channel made of heat insulating materials is fixedly arranged at the glass fiber discharge port, one end of the flexible channel is connected with the mixing port of the machine barrel, and the other end of the flexible channel is connected with the glass fiber discharge port. The flexible channel may be made of a heat insulating rubber material. Therefore, the glass fiber enters the glass fiber cache preheating cavity and then is in a closed environment until reaching the inside of the machine barrel, so that heat loss is avoided, and the preheating effect is ensured.

The further technical scheme is that the wire hanging rod is fixedly arranged on the rack and horizontally arranged, and a plastic sleeve is rotatably sleeved on the wire hanging rod; the middle part of the plastic sleeve is provided with a ring groove for hanging the glass fiber. Like this directly to be taken during the fine material loading of glass directly to hang on the hanging wire pole in the past, the time has been for a long time on the hanging wire pole corrosion etc. easily abrade fine or make and bring impurity into after the fine feeding of glass, can avoid this problem behind the adoption plastic sheathing, the annular then plays the effect of direction, guarantees that fine falling into on the plastic sheathing rather than slipping from the plastic sheathing.

The technical scheme is that a plurality of glass fiber finished product roll placing plates are hinged to a rack below the machine barrel, and the glass fiber finished product roll placing plates are arranged from top to bottom. Therefore, the occupied area of the glass fiber finished product roll is reduced after the arrangement, and the glass fiber finished product roll placing plate is rotated and folded when the production is not carried out, so that the occupied space of equipment is saved.

The utility model has the advantages and the beneficial effects that: aiming at high glass fiber products, glass fiber materials on glass fiber rolls are preheated before being mixed, so that the requirements of energy conservation and consumption reduction are met; the glass fiber feeding process is soft, the raw material glass fiber is not damaged, and impurities are not brought in the glass fiber feeding process. The glass fiber is properly preheated before feeding by utilizing the residual temperature of the cylinder wall of the machine cylinder before feeding the glass fiber, so that the melting heat required by the glass fiber mixed with PA after entering the machine cylinder is reduced, and the consumption of heat energy is reduced. Considering that the surface area of the machine barrel is increased instead by the arrangement of the protruded square box, the heat dissipation area is easily increased, and therefore the square box is made of heat insulation materials to reduce the heat dissipation. The glass fiber enters the glass fiber cache preheating cavity and then reaches the inside of the machine barrel, the glass fiber cache preheating cavity is in a closed environment, heat loss is avoided, and the preheating effect is guaranteed. Directly take the string on the hanging wire pole when not having glass fibre material loading in the past, corrosion etc. easily abrade glass fibre or bring impurity into after making the glass fibre feeding on the hanging wire pole after the time has been of a specified duration, can avoid this problem behind the adoption plastic sheathing, the annular then plays the effect of direction, guarantees that glass fibre falls into on the plastic sheathing rather than slips from the plastic sheathing. The occupied area of the glass fiber finished product roll is reduced, and the glass fiber finished product roll placing plate is rotated and folded when the glass fiber finished product roll is not produced, so that the occupied space of equipment is saved.
