Abstract
The utility model relates to an enhanced feeding device of a hopper of a bottle cap extruder. The enhanced feeding device comprises a screw rod of an extruder, wherein the screw rod comprises a material roller which is driven to rotate by a motor, a left stirring rod, a right stirring rod and an extruding blade are arranged on the material roller, the diameters of two ends of the material roller are less than the diameter of the middle part of the material roller, the extruding blade is arranged from the outer wall of the middle part of the material roller, is of a spiral shape and downwards stretches to the bottom of the material roller, and the width of the extruding blade at the middle part of the material roller is more than that of the extruding blade at the bottom of the material roller. According to the enhanced feeding device of the hopper of the bottle cap extruder, materials enter the hopper of the extruder, the material roller is driven to rotate by a low-speed torsion motor, the materials are uniformly stirred by the stirring rods, the inverted-trapezoid spiral extruding blade at the outer wall of the material roller is matched with the material roller to stir the materials in the hopper by rotation, an extruding force from top to bottom is generated on the materials, and the materials are forced to be discharged towards a spiral direction of the screw rod of the extruder, the extruding of the materials by the screw rod is improved, the occurrence of the material reverting is avoided, the feeding is guaranteed to be uniform and stable, and the lid making requirement is met.
Description
Technical field
The utility model relates to plastic extruder, particularly relates to the reinforced pay-off of plastic bottle closure extruder hopper, mainly for the production of bottle caps such as mineral water bottle, oil bottles.
Background technology
Produce the equipment of the plastic bottle closures such as mineral water bottle, edible blend oil, mainly comprise extruder, scraper feed mechanism and compression molding system, after the plastics that extruder is extruded arrive discharging opening, delivered in the die forming machine by the quantitative material of the each scraping of scraping mechanism, because the speed of bottle cap processed is very fast, and each feeding amount is fewer, so require the scraping material accurate, otherwise scraper is too much, cause waste, scraper is very few, causes that bottle cap lacks material and is difficult to moulding, causes and scraps, it is accurate to reach each scraper amount, at first requires the discharging of extruder even.Because extruder relies on screw rod that material is extruded, and because of the characteristic of screw rod, does not only have charging on the N cambered surface, can produce down returning charge on the contrary, because plastics have the characteristic of light weight, how can cause the feed of extruder discharging mouth unstable again.When the feed of extruder discharging mouth occurs when unstable, just make scraper, feeding inhomogeneous, cause at last the plastic bottle closure of mold pressing to go out waste product.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provide a kind of and at the extruder hopper mandatory feed mechanism is set, the raising screw rod is extruded material, guarantees that feed is stable, satisfies the reinforced pay-off of plastic bottle closure extruder hopper that system is covered needs.
The technical scheme of the reinforced pay-off of the utility model plastic bottle closure extruder hopper is: the screw rod that comprises extruder, described screw rod comprises material roller, material roller rotates through driven by motor, two stirring bars and material extrusion blade about being shaped with on the material roller, it is characterized in that the diameter at described material roller two is less than the diameter at middle part, outer wall begins to be shaped with the material extrusion hinge at the material roller middle part, the material extrusion hinge is twist down to the material roller bottom, and the hinge width of described material extrusion hinge in the middle part of material roller is greater than the hinge width of bottom.
The utility model discloses the reinforced pay-off of a kind of plastic bottle closure extruder hopper, when material enters in the hopper of extruder, rotated by low speed torsion driven by motor material roller, two stirring bars stir material about material roller top, make material stirring even, and the terraced spiral material extrusion hinge of falling on the material roller outer wall cooperates the thick material roller of two detail section, stir material in hopper by rotation, and to a kind of extruding force from top to down of material generation, force material toward the hand of spiral feed of extruder screw, the raising screw rod is extruded material, avoids producing returning charge, guarantee the even of feed, stable, satisfy system and cover needs.
Description of drawings
Fig. 1 is the schematic perspective view of the reinforced pay-off of plastic bottle closure extruder hopper.
The specific embodiment
The utility model relates to the reinforced pay-off of a kind of plastic bottle closure extruder hopper, as shown in Figure 1, the screw rod 1 that comprises extruder, described screw rod comprises material roller 2, material roller rotates through driven by motor, two stirring bars 3 and material extrusion blade 4 about being shaped with on the material roller, it is characterized in that the diameter at described material roller 2 two is less than the diameter at middle part, outer wall begins to be shaped with material extrusion hinge 4 at the material roller middle part, the material extrusion hinge is twist down to the material roller bottom, and the hinge width of described material extrusion hinge 4 in the middle part of material roller is greater than the hinge width of bottom.When material enters in the hopper of extruder, by 2 rotations of low speed torsion driven by motor material roller, 3 pairs of materials of two stirring bars stir about material roller top, make material stirring even, and the terraced spiral material extrusion hinge 4 of falling on material roller 2 outer walls cooperates the thick material roller 2 of two detail section, stir material in hopper by rotation, and to a kind of extruding force from top to down of material generation, force material toward the hand of spiral feed of extruder screw 1, improve extruding of 1 pair of material of screw rod, avoid producing returning charge, guarantee the even, stable of feed, satisfy system and cover needs.
