Adopt a kind of mechanical transmission-type of the present invention to draw a kind of mechanical transmission-type of method of designing design-calculated of bag mechanism to draw bag mechanism, it comprises front apron 2, back shield 7, reinforced rib 9, motor 10, gear, it is characterized in that: further comprising be fixed between front apron 2 and the back shield 7, two torque rod assemblies 1 of consistency from top to bottom; Torque rod assembly 1 is made up of axis 12, clamping bar 13, plum blossom flywheel 18, torsion spring 15, pin 16, torsion spring gim peg 17, last curved boom 14; Axis 12 passes the inboard that front apron 2 and 7, two plum blossom flywheels 18 of back shield are pressed close to front apron 2 and back shield 7, is sleeved on the two ends of axis 12; The top of four spiders of plum blossom flywheel 18 all has draw-in groove, and last curved boom 14 lower ends are embedded in the described draw-in groove, is linked at by the torsion spring gim peg 17 that is with torsion spring 15 on four spiders of plum blossom flywheel 18; The upper arm of torsion spring 15 hangs on the pin 16 that is fixed in curved boom 14 lateral surfaces, and the underarm of torsion spring 15 is fixed on the same spider lateral surface of plum blossom flywheel 18; Four clamping bars 13 are parallel with axis 12, and two ends are fixed on the upper end of curved boom 14.
As shown in Figure 1: front apron 2 and back shield 7 two couples by upper and lower side (four) reinforced rib 9 is fixed as one, motor 10 is fixed on the electric machine support 8, be arranged on the same side of back shield 7 with gear cluster, the torsion bar general name 1 of two consistencies from top to bottom is fixed between back shield 7 and the front apron 2, the axis 12 of torsion bar 1 passes front apron 2 and back shield 7, the lower end of front apron 2 opposite sides is fixed with photoelectric switch 1, and described gear comprises: a pair of large straight gear 4, a large umbrella gear 5 and a small umbrella gear 6; Motor 10 shaft heads overlap a small umbrella gear 6; Small umbrella gear 6 meshes with large umbrella gear 5 in vertical direction, large umbrella gear 9 is connected with a pair of intermeshing large straight gear 4 by the axis 12 of the torsion bar general name 1 of below, and intermeshing large straight gear 4 is placed in respectively on the axis 12 of two torsion bars 1 up and down.
Motor 10 is connected with small umbrella gear 6, is meshed with large umbrella gear 5 by small umbrella gear 6, drives straight gear 4 and rotates, and is in contact with one another thereby drive torsion bar general name 1, realizes the encapsulation of object and draws bag descending.
As Fig. 2, Fig. 3, shown in Figure 4: torque rod assembly 1 by axis 12, clamping bar 13, plum blossom flywheel 18, torsion spring 15, pin 16, torsion spring gim peg 17, go up curved boom 14 and form; Axis 12 passes the inboard that front apron 2 and 7, two plum blossom flywheels 18 of back shield are pressed close to front apron 2 and back shield 7, is sleeved on the two ends of axis 12; The top of four spiders of plum blossom flywheel 18 all has draw-in groove, and last curved boom 14 lower ends are embedded in the described draw-in groove, is linked at by the torsion spring gim peg 17 that is with torsion spring 15 on four spiders of plum blossom flywheel 18; The upper arm of torsion spring 15 hangs on the pin 16 that is fixed in curved boom 18 lateral surfaces, and the underarm of torsion spring 15 is fixed on the same spider lateral surface of plum blossom flywheel 18; Four clamping bars 13 are parallel with axis 12, and two ends are fixed on the upper end of curved boom 14.The full swing angle is 30 ° between the spider of described upward curved boom 14 and plum blossom flywheel 18.Torque rod assembly right side view of the present invention is identical with Fig. 3 left side view.Described torsion spring 15 is to be entwined by stainless steel wire, and spring 15 upperarm lengths are that 12. 5mm, upper end curve the opening crotch that diameter is 5mm, and 15 times brachiums of spring are 12. 5mm.
Torsion spring gim peg 17 is in orthogonal position with axis 12, clamping bar 13.Because torsion spring 15 only just can reverse under certain stress condition, when no external force put on torque rod assembly 1, torsion spring 15 was in its state of nature all the time, and any elastic deformation does not promptly take place.When motor 10 starts, when driven gear and axis 12 rotate, because the mutual contraposition contact of every group of clamping bar 13, make extraneous stress put on curved boom 14, simultaneously, the extraneous stress of torsion spring 15 impressions carries out elastic deformation, curved boom 14 carries out bending in the drive, at this moment, one group of clamping bar being in contact with one another 13 continues running downwards, and the spider bending of going up curved boom 14 and plum blossom flywheel 18 in an angle, when the angle angle is increased to certain value (being not more than 30 °), one group of clamping bar 13 of contraposition separates, and at this moment, does not have extraneous stress and puts on the torsion spring 15, torsion spring 15 sets back, last curved boom 14 is 0 ° with the spider angle of plum blossom flywheel 18, and last curved boom 14 is the straight-bar state with the spider of plum blossom flywheel 18, and object is descending smoothly with the separation of this group clamping bar 13.Be in on-state as motor 10, then every group of torque rod assembly 1 all repeats this state of kinematic motion always.Stop energising as motor 10, then torque rod assembly 1 is in the flashy state of outage, switches on until next time.
Method of designing of the present invention makes and adopts design-calculated of the present invention to draw bag mechanism that volume is little, and is safe and convenient to use, can handle material whenever and wherever possible owing to adopt integrated design.
