Description
Technical field
The utility model is related to extruder, especially a kind of novel plastic extrusion machine.
Background technology
In plastic extruding forming equipment, plastic extruder is normally referred to as host, and the follow-up equipment mating with it is moulded
Expect that extrusion shaping machine is then known as subsidiary engine.Plastic extruder (host) can with tubing, film, hold in both hands material, monofilament, flat filament, strap,
The various plastic shaping subsidiary engine matchings such as net, plate (piece) material, profile shapes, granulation, cable cladding are squeezed, form various plastic extruding formings
Production line produces various plastic products.Therefore, plastic extruding forming machinery no matter now or in the future, be all plastic processing industry
In one of the machine be used widely.The host of plastic extruder is extruding machine, it is cooled down by screw rod, driving mechanism and heating
Mechanism forms, and the effect of driving mechanism is to drive screw rod, feed screw required torque and rotating speed in extrusion, usually
It is made of motor, retarder and bearing etc., and during plastic molten melt, needs just make plastics by spiro rod length setting is longer
Fragment becomes molten condition, if screw rod it is too short or in casing the residence time it is too short, it is not complete to be easy to cause plastic pieces
Running down；Without clearing up metal in material and other sundries during feed intake, it is easily damaged the components such as screw rod, foreign matter
It is not easy to take out in into machine, wastes raw material；The plurality of raw materials of input is all put into modeling again by mixing machine mixing in advance
Expect in extruder, it is close since the density of different material, grain size are different when raw material is put into the charge door of plastic extruder
Larger, the smaller more bottoms for being in charge door of grain size are spent, the raw material that density is smaller, grain size is larger is more in charge door
Top causes the plastics plurality of raw materials entered in casing to be unevenly distributed, and coloring is uneven, influences product quality.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides a kind of novel plastic extrusion machine, solves
Plastic raw materials cannot melt in time, and charging is uneven and is not avoided that the problem of sundries such as metal enter in machine.
To achieve the above object, the utility model employs following technical solution：
A kind of novel plastic extrusion machine, including casing, supporting rack, screw rod, driving mechanism and heating arrangements, heating arrangements and
Screw rod is all located in casing, and one end of screw rod and the output axis connection of driving mechanism, driving mechanism and casing are located on supporting rack,
It is characterized in that：Screw pitch in the middle part of screw rod is less than the screw pitch at screw rod both ends, and casing one end is equipped with charge door, and charge door inner wall is equipped with
Magnet adsorption layer is additionally provided with inclined isolation board in charge door and charge door is divided into two by isolation board, one end of isolation board with
One side bottom of charge door inner wall is affixed and charge door with isolation board in funnel-form, isolation board is equipped with multiple openings and multiple opens
Mouth is located at the upper, middle and lower of isolation board respectively, and valve is equipped in multiple openings；Feed inlet inner wall is consolidated with isolation board
Connect and locate opposite side and be equipped with transparent windows, one end and the feed inlet outer wall of observation window are hinged, the other end of observation window and into
The outer wall of material mouth is equipped with the latching device to match；The other end of casing is equipped with discharge port, the bottom angled of discharge port.
Compared with the prior art, the utility model has the advantages that：
1. being equipped with inclined isolation board in feed inlet, three on isolation board are open can open opening as needed, three
A opening can cause the raw material of different densities and grain size is uniformly added into casing to process, keep away positioned at the different parts of isolation board
Exempting from addition raw material unevenness causes plastic quality bad.
2. the screw pitch in the middle part of screw rod is less than the screw pitch at screw rod both ends, the raw material that the intensive screw thread in screw rod middle part makes rests on spiral shell
Time and travel in the middle part of bar is elongated so that raw material fully melts.
3. in the factory for processing a large amount of plastics, inevitably have metal class sundries and be mixed into raw material, magnet adsorption layer is effective
Metal sundries when avoiding charging enter the situation of casing with raw material.
