Special adhesive tape for novel half-feeding rice harvester
Technical field
The present invention relates to a kind of drive belt, particularly relate to a kind of special adhesive tape for novel half-feeding rice harvester.
Background technique
Half feeding rice harvester drive belt because of Environmental Conditions harsh, be easily absorbed in earth, require higher to the tensile strength of adhesive tape, simultaneously due to adhesive tape in use working surface extrude by belt wheel, require that adhesive tape has higher lateral stiffness.At present, there is lateral stiffness difference in half traditional feeding rice harvester drive belt, transmission power is low, and the shortcoming of impact resistance difference and resistance to reverse flexibility difference, causes the working life of drive belt shorter.
Summary of the invention
The object of the present invention is to provide a kind of special adhesive tape for novel half-feeding rice harvester, it has, and impact resistance is strong, and transmitted power is high, the feature of the good and long service life of resistance to reverse flexibility.
The object of the invention is to be achieved through the following technical solutions:
A kind of special adhesive tape for novel half-feeding rice harvester, it is coated on primer within infantees and face glue, and wherein, arrange aramid fiber tension cotton rope between described primer and face glue, and be all embedded with short fibre in described primer and face glue, described infantees adopts Wide-angle cloth.
Especially, described Wide-angle cloth is greater than angle in transverse direction in the angle of longitudinal direction.
Especially, described Wide-angle cloth is 120 ° in the angle of longitudinal direction, is 60 ° in the angle of transverse direction.
Beneficial effect of the present invention is, described special adhesive tape for novel half-feeding rice harvester uses aramid cord as tensile materials, improves impact resistance and the transmitted power of adhesive tape; In primer, bury horizontal short fibre underground, improve the lateral stiffness of adhesive tape, in the glue of face, add short fibre, substantially increase the lateral stiffness of adhesive tape, improve the transmission efficiency of adhesive tape; Infantees uses Wide-angle cloth, improves the resistance to reverse flexibility of adhesive tape.

Fig. 2 is the graticule structural drawing of the infantees of special adhesive tape for novel half-feeding rice harvester of the present invention.
In figure:
1, primer; 2, face glue; 3, aramid fiber tension cotton rope; 4, infantees; 5, short fibre.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of special adhesive tape for novel half-feeding rice harvester, it is coated on primer 1 within infantees 4 and face glue 2, arrange aramid fiber tension cotton rope 3 between described primer 1 and face glue 2, and be all embedded with short fibre 5 in described primer 1 and face glue 2, described infantees 4 adopts Wide-angle cloth, described Wide-angle cloth in angle A=120 ° of longitudinal direction, in angle B=60 ° of transverse direction.
Described aramid fiber tension cotton rope 3 is as tensile materials, improve impact resistance and the transmitted power of adhesive tape, because reaper is in use easily absorbed in earth, now adhesive tape will bear very large impact force, aramid cord has the advantages that tensile strength is high, elongation rate of tensile failure is low, most suitable as the framework material of adhesive tape.
Bury horizontal short fibre 5 underground in described primer 1, improve the lateral stiffness of adhesive tape, in face glue 2, also add short fibre 5, substantially increase the lateral stiffness of adhesive tape, improve the transmission efficiency of adhesive tape.
Described infantees 4 uses Wide-angle cloth, improves the resistance to reverse fatigability of adhesive tape.It is the feature of A=120 °, good springiness that Wide-angle cloth has in the angle of longitudinal direction, and in angle B=60 ° of transverse direction, substantially increases the longitudinally flexible of adhesive tape.
