Technical Field
The utility model relates to the technical field of plastic extrusion, in particular to plastic film raw material mixing equipment.
Background
Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging, and as a film coating, and the plastic films are processed by a plastic extruder.
A plastic extruder is an apparatus for producing plastic articles by adding thermoplastic particles (e.g., polyethylene, polypropylene, etc.) to the barrel of an extruder and then extruding them into a desired shape at high temperature and pressure. Such equipment is widely used in the manufacture of various plastic articles such as pipes, sheets, films, containers, etc.
The main components of the plastic extruder comprise:
and (3) a feeding system: comprises a feed hopper, a feeder, a feed inlet and the like, and is used for feeding granular plastic raw materials into a screw cylinder for extrusion.
And (3) a screw rod: is the core component of the extruder and is typically made of high strength alloy steel. During rotation of the screw, the plastic granules are gradually heated and extruded by friction and pressure.
However, the feeding system introduces raw materials into the screw barrel, moves to a melting area under the conveying of the screw rod, is extruded and led out, but the raw materials are pushed forward by the helical blades of the screw rod, the mixing effect is poor, so that the raw materials are unevenly distributed, and when melting is caused, the raw material proportions are different, so that the extrusion quality of the plastic film is affected.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model provides plastic film raw material mixing equipment.
The utility model provides the following technical scheme: the utility model provides a plastic film raw materials mixing arrangement, includes the screw rod of extruder, the screw rod includes the pay-off region and melts regional and installation region, install a plurality of groups puddler that become spiral distribution on the pay-off region, the end of screw rod is installed and is used for carrying out the mixing end of stirring to the material that melts, and the surface of mixing end is equipped with a plurality of groups and is used for stirring the sawtooth of material.
Preferably, a baffle plate for blocking the material is arranged on the screw rod between the feeding area and the installation area.
Preferably, the height of the stirring rod does not exceed the heights of the helical blades of the feeding area and the melting area.
Preferably, fan blades for mixing materials are arranged on the screw rod between the feeding area and the melting area.
Preferably, the diameter of the rotation of the fan blade does not exceed the diameter of the spiral blade in the feeding area and the melting area.
Compared with the prior art, the utility model has the following beneficial effects:
this plastic film raw materials mixing apparatus, raw materials are carried in the pay-off district, and the puddler on it can constantly stir the raw materials under the rotation of screw rod, makes its distribution even, and melts the back in melting the district at the raw materials, under the stirring of mixing the end, further mix for the raw materials intensive mixing that melts, thereby guarantee the quality after the material is extruded.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
In the figure: 1. a screw; 2. a feeding area; 3. a melting region; 4. a mounting area; 5. a stirring rod; 6. a mixing end; 7. a baffle; 8. and (3) a fan blade.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, a technical solution of the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings of the embodiments of the present disclosure, and detailed descriptions of known functions and known components are omitted from the present disclosure in order to avoid unnecessarily obscuring the concept of the present disclosure.
Referring to fig. 1, a plastic film raw material mixing apparatus includes a screw 1 of an extruder, the screw 1 includes a feeding area 2, a melting area 3, and a mounting area 4, raw materials fall into the feeding area 2 through a feeding system, and rotation of the screw 1 causes spiral blades on the feeding area 2 and the melting area 3 to push the raw materials forward, so that the raw materials are led out.
The stirring rods 5 which are distributed in a spiral mode are arranged on the feeding area 2, the heights of the stirring rods 5 are not higher than the heights of the spiral blades of the feeding area 2 and the melting area 3, the spiral blades of the feeding area 2 are only used for pushing raw materials to move forward, therefore, the stirring effect is poor, the raw materials are conveyed in the feeding area 2, the stirring rods 5 on the feeding area 2 continuously stir the raw materials under the rotation of the screw 1, so that the raw materials are uniformly distributed, the mixing of the raw materials is enhanced, various raw materials are uniformly distributed, and the raw materials are led into the melting area 3 in such a way, and the proportion of the melted materials is close to that of the raw materials.
The baffle 7 for blocking the material is arranged on the screw 1 between the feeding area 2 and the mounting area 4, one end of the charging barrel is prevented from being blocked by the baffle 7, the spiral blade on the feeding area 2 can convey the material, but the material is excessively concentrated between the feeding area 2 and the mounting area 4, and the feeding area 2 cannot convey the material, so that the material is isolated by the baffle 7 and prevented from entering the area between the feeding area 2 and the mounting area 4.
The end of the screw 1 is provided with a mixing end 6 for stirring the melted material, the surface of the mixing end 6 is provided with a plurality of groups of saw teeth for stirring the material, and the rotation of the screw 1 can drive the saw teeth on the mixing end 6 to stir the melted raw materials, so that the raw materials are further mixed.
Install the flabellum 8 of mixed material on the screw rod 1 between pay-off region 2 and the region of melting 3, the rotatory diameter of flabellum 8 does not exceed the spiral blade diameter in pay-off region 2 and the region of melting 3, and the spiral blade size between pay-off region 2 and the region of melting 3 is different, melts regional 3 and compares pay-off region 2 spiral blade more closely, therefore the material is too much concentrated in the region between pay-off region 2 and the region of melting 3 easily, mixes the raw materials through flabellum 8, later melts by melting regional 3 transport, improves the raw materials mixing effect.
The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
