Abstract
The utility model discloses an injection molding machine suitable for bioplastics. The injection molding machine is composed of a screw head, a loosing section, a pressure reducing section, a homogenizing section, a compressing section and a feeding section which are arranged in sequence, wherein the screw head is conical. Compared with a common screw, the injection molding machine screw rod provided by the utility is additionally provided with the loosing section and the pressure reducing section, so that the shearing force is small, biodegradation for material degrading can not be caused; due to the proper arrangement of the loosing section, the depth of a screw groove is increased, the severe shearing to materials is alleviated, a melt is uniformly heated, pressure and temperature fluctuation is eased, and simultaneously improvement of the plasticizing capacity of the screw rod and reduction of the power consumption are facilitated; and the head of the screw rod is changed to be conical so as to beneficial to thorough material discharging during injection, and avoid the overheated degrading phenomenon caused by overlong staying time of the melt in a charging barrel, and therefore, the difficulty that the common screw rod can not be suitable for injecting bioplastics is solved.
Description
Technical field
The utility model relates to a kind of injection machine accessory, particularly a kind of screw in injection molding machine.
Background technology
The structure of common screw as shown in Figure 1, this screw rod is made of screw head A, homogenizing zone B, compression section C and feeding section D, screw head A is by crossing glue head 1, cross cushion rubber 2, cross glue meson 3 and constitute, and this screw rod is fit to that injection moulding processing plasticity is good, the plastics of Heat stability is good.At present, the raw material of injection moulding has a kind of biodegradable plastic, biodegradable plastic refers to can resolve into class plastics of micromolecular compound under the effect of the microorganism that nature exists such as bacterium, fungi, mould and algae, its processing characteristics is bad, flowability and heat endurance are very poor, exist fusion speed slow with common screw injection moulding always, and temperature fluctuation is big, plastify shortcomings such as inhomogeneous, easy degraded.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of screw in injection molding machine that is applicable to biological plastics.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of screw in injection molding machine that is applicable to biological plastics is made of the screw head that is arranged in order, slack sections, decompression section, homogenizing zone, compression section, feeding section, and described screw head is taper.
The beneficial effects of the utility model are: screw rod of the present utility model is compared with common screw, increased slack sections, the decompression section, shear less, can not cause the biodegradation that material decomposes, slack sections has suitably increased spiral groove depth, reduced the violent shearing to material, cause melt to be heated evenly, reduced the pressure and temperature fluctuation, also help the plasticizing capacity that improves screw rod simultaneously and reduce power consumption, change screw head into taper, discharge is clean when being conducive to inject, prevent that melt from resting in the barrel overlong time and producing the phenomenon of thermal degradation, has solved the difficult problem that common screw is not suitable for the injection moulding biological plastics.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of common screw;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 2, a kind of screw in injection molding machine that is applicable to biological plastics is made of the screw head A, the slack sections E that are arranged in order, decompression section F, homogenizing zone B, compression section C, feeding section D, and described screw head A is taper.
Screw rod of the present utility model is compared with common screw, increased slack sections, the decompression section, shear less, can not cause the biodegradation that material decomposes, slack sections has suitably increased spiral groove depth, reduced the violent shearing to material, cause melt to be heated evenly, reduced the pressure and temperature fluctuation, also help the plasticizing capacity that improves screw rod simultaneously and reduce power consumption, change screw head into taper, discharge is clean when being conducive to inject, prevent that melt from resting in the barrel overlong time and producing the phenomenon of thermal degradation, has solved the difficult problem that common screw is not suitable for the injection moulding biological plastics.
