The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, exhibition yarn balance tension of the present utility model mechanism, this exhibition yarn balance tension mechanism comprise that support 10, supporting mechanism, equalization of strain are opened up fine device and promoted equalization of strain and open up the adjustable pushing power apparatus that fine device carries out folding.The below is elaborated to every part:
With reference to Fig. 3, an end of supporting mechanism is fixed on the support, and supporting mechanism is positioned at the side that equalization of strain is opened up fine device.Because the structure of support is more single, equalization of strain open up fine device one end and support shape shape hinged after, supporting mechanism mainly is the auxiliary other end that equalization of strain is opened up fine device that connects, like this, all there is the strong point at the two ends that make equalization of strain open up fine device, under the active force of adjustable pushing power apparatus, can make equalization of strain open up fine device and carry out folding.The supporting mechanism preferred forms is in the utility model: supporting mechanism comprises roller shaft 20, bearing 21, end cap 22 and bindiny mechanism, one end of roller shaft 20 is connected with end cap 21, be fixed with the first screw 23 on the end cap 21, this first screw can be connected with equalization of strain fine device by extension spring and connect.The other end of roller shaft 20 is connected with bearing 21, and bearing 21 is fixedly connected with bindiny mechanism.This bindiny mechanism comprises sleeve 24, connection cover 25, back shaft 26, sleeve 24 is enclosed within on the bearing 21, connection cover 25 is fastenedly connected with the axial end of sleeve, one end of back shaft 26 is inserted in the sleeve after passing connection cover 25, the other end of back shaft 26 and support 10 are fixing, back shaft is provided with the second screw 27, and this second screw can be connected with equalization of strain fine device by extension spring and connect.
Certainly, the supporting mechanism in the utility model also can adopt the structure of comparatively simplifying, and namely supporting mechanism just is a support bar.
See figures.1.and.2, it is hinged that equalization of strain is opened up an end and the support of fine device, and the other end that equalization of strain is opened up fine device is connected with supporting mechanism by extension spring.Under the effect of adjustable pushing power apparatus, equalization of strain is opened up fine device and can be rotated around bearing pin like this, simultaneously by the effect of extension spring, can avoid left swing arm or right swing arm self to rotate around bearing pin under Action of Gravity Field.Described equalization of strain is opened up fine device and is comprised left swing arm 30, right swing arm 31, pressure roller 32, are connected with right swing arm with left swing arm 30 respectively and are connected in the two ends of pressure roller 32, one end of left swing arm 30 and right swing arm 31 is articulated in respectively on the support 10, the other end that left swing arm 30 is connected with right swing arm connects respectively attaching parts that are used for extension spring 33, these attaching parts comprise bearing 34 and the bolt 35 that is L-type, one end of bearing 34 is provided with through hole, bolt 35 is clamped on the bearing by binding nut 36, one end of bolt 35 is provided with the hole that connects extension spring 33, and extension spring is articulated in this hole.The other end of bearing 34 is fixed on left swing arm or the right swing arm.The end of left swing arm and right swing arm is fixed with respectively the thrust part 37 that contacts with the adjustable pushing power apparatus, and this thrust part 37 is bearing.Under the active force of adjustable pushing power apparatus, promote thrust part 37, by thrust part 37 with transmission of power to left swing arm 30 or right swing arm 31, left swing arm 30 or right swing arm 31 are rotated around bearing pin, so that opening up fine device, equalization of strain carries out open and close movement like this, because yarn can be opened up fine device through equalization of strain, when equalization of strain is opened up fine device and is opened, yarn is balanced at the pulling force of input and output, when equalization of strain under the extension spring effect is opened up fine device closure, yarn imposed add a pressure-acting, yarn is formed the fine effect of exhibition.
