In order to solve the problem of above-mentioned proposition; The utility model provides following technological scheme: a kind of netting machine free wheel device; Comprise that star-wheel, outer toroid, said outer toroid are installed on the star-wheel outside, said star-wheel outer rim is provided with the wedge gap, the built-in roller in said wedge gap; Said wedge gap is surrounded by base, side and star-wheel external arc, and the base in said wedge gap and the angle of side are greater than 90 °.
Preferably, the netting machine free wheel device of the utility model, the material of said star-wheel, outer toroid are Gcr15, the material Gcr15SiMn of said roller.
Preferably, the netting machine free wheel device of the utility model, said star-wheel external diameter are greater than 100mm, and the quantity in said wedge gap is 5, is uniformly distributed in the outer rim of said star-wheel.
Preferably, the netting machine free wheel device of the utility model, said star-wheel external diameter is less than or equal to 100mm, and the quantity in said wedge gap is 3, is uniformly distributed in the outer rim of said star-wheel.
Preferably, the netting machine free wheel device of the utility model, the inboard of said star-wheel also is provided with keyway.
Preferably, the netting machine free wheel device of the utility model, the base in said wedge gap and the angle of side are 115 °.
Preferably, the netting machine free wheel device of the utility model also is provided with clearance groove on the side in said wedge gap, and being shaped as of said clearance groove is cylindrical.
Preferably, mounting spring in the netting machine free wheel device of the utility model, said clearance groove is installed ejector pin on the said spring.
Preferably, the netting machine free wheel device of the utility model, the diameter of said roller is greater than the diameter of said clearance groove.
Preferably, the netting machine free wheel device of the utility model, the diameter of said roller equals the diameter of said clearance groove.
After adopting said structure, the utlity model has following beneficial effect:
1, can make the netting machine free wheel device realize unidirectional drive outer toroid rotation simply and easily;
2, make the quantity of this netting machine free wheel device working stability, high life, the sick net of reduction, improved the knitmesh quality.
Description of drawings
Fig. 1 is the utility model first embodiment's a structural drawing;
Fig. 2 is the sectional view of the A-A direction shown in Figure 1 of the utility model;
Fig. 3 is the utility model second embodiment's a structural drawing.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
Embodiment one
Referring to Fig. 1-shown in Figure 2; The utility model provides a kind of netting machine free wheel device; Comprise that star-wheel 1, outer toroid 2, said outer toroid 2 are installed on star-wheel 1 outside, said star-wheel 1 outer rim is provided with wedge gap 3, said wedge gap 3 built-in rollers 4; Said wedge gap 3 is surrounded by base 31, side 32 and star-wheel 1 external arc, and the base 31 in said wedge gap 3 and the angle of side 32 are greater than 90 °; Wherein, the material of said star-wheel 1, outer toroid 2 is Gcr15, the material Gcr15SiMn of said roller 4; When said star-wheel 1 external diameter during greater than 100mm, the quantity in said wedge gap 3 is 5, is uniformly distributed in the outer rim of said star-wheel 1; The inboard of said star-wheel 1 also is provided with keyway 5; The base 31 in said wedge gap 3 is 115 ° with the angle of side 32; Also be provided with clearance groove 6 on the side 32 in said wedge gap 3, being shaped as of said clearance groove 6 is cylindrical; Mounting spring 8 in the said clearance groove 6 is installed ejector pin 7 on the said spring 8; The diameter of said roller 4 is greater than the diameter of said clearance groove 6.
The concrete working procedure of the utility model is: in use, an axle is installed, through the rotation of axle and the effect of keyway 5 on star-wheel 1 inboard; To drive star-wheel 1 rotation, when star-wheel 1 turned clockwise, the roller 4 that is positioned at wedge gap 3 i.e. the less clearance in the leftmost side in wedge gap 3; Hold out against roller 4 by ejector pin 7; At this moment, because the effect of roller 4 drives outside outer toroid 2 and rotates together; When star-wheel 1 is rotated counterclockwise; The roller 4 that is positioned at wedge gap 3 is promptly in bigger gap, the rightmost side in wedge gap 3; And can get on the side 32 of being located at wedge gap 3 in the clearance groove 6, ejector pin 7 is return under the effect of roller 4 in star-wheel 1 hole, thereby; Because do not have the effect of roller 4, outer toroid 2 is along with star-wheel 1 rotates together.
