The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

Referring to accompanying drawing 1-10, in the present embodiment, this adjustable speed changing box curtain machine, the top of its frame 1 is equipped with and is pushed away screen frame (unit) 24 and line crotch 25, a plurality of line forks are housed on the line crotch 25, and each line fork connects transmission with chain 26, and transmission device is installed in the bottom of frame 1, belt wheel combination comprises the driven pulley 10 and the small pulley 3 that are sleeved on the driving shaft 4, is sleeved on the big belt wheel 2 on the driven shaft 12 in this transmission device, and wherein driven pulley 10 is connected transmission with the output shaft of motor by being with.With the organic gear 5 of engagement on the gear wheel 7 of driven pulley 10 coaxial settings, with the chain 26 that is with on the driven sprocket 6 of these machine gear 5 coaxial packages with line fork interlock.Wherein: on the cam 15 in the transmission device rolling bearing 16 is housed, the power transmission shaft 17 of this cam 15 is connected transmission with driven shaft 12 usefulness conical tooth wheels 14, the axle head of driven shaft 12 is hinged by bolt and crank 13, this crank 13 1 ends and rod hinge connection, and the connecting rod other end has an adjustable plate 9 with bolting, this adjustable plate 9 is sleeved on the axle head of driving shaft 4, also is set with pinion 8 and gear wheel 7 on the driving shaft 4 of adjustable plate 9 inboards successively, and gear wheel 7 is meshed with machine gear 5.Frame 1 top push away the travelling carriage 22 that is welded with a coherent arc on the screen frame (unit) 24, with bolting fork-shaped locating rack 21 is arranged on the line crotch 25, a pulley 23 is housed on this locating rack 21, this pulley 23 places on the travelling carriage 22, in pushing away the process that screen frame (unit) 24 boosts and fall, this pulley 23 slides on travelling carriage 22.

Big belt wheel 2 is the stepped speed change belt wheels in side, driving belt can be sleeved on the wheel of different ladders, to realize speed change; And cam 15 is the shift cam of helicoidal structure, and its lateral surface is also stepped, can be by rolling bearing 16 is placed on the not contour wheel face, to realize pushing away the motion change of screen frame (unit) 24.

Adjustable plate 9 is a rectangular block, and its lower end is welded with an annulus cover, is used to be sleeved on the axle head of driving shaft 4, and adjustable plate 9 is provided with the end that four adjustment holes 18 are used to be connected and fixed connecting rod, also is provided with one and is used for fixing the circular hole of dialling plate 19.Pinion 8, group plate 19 and adjustable plate 9 constitute speed change moving tooth mechanisms.

Gear wheel 7 is provided with four circle holes 20, this locating hole 20 is groove, the hole count of its ecto-entad is followed successively by 12 holes, 6 holes, 4 holes, 3 holes, in addition, a locating piece 11 also is installed on the frame 1, ball is equipped with in the inside of this locating piece 11, and this ball is placed in the locating hole 20 on the gear wheel 7 according to actual needs, improves the stability of speed change moving tooth.

With the reed curtain is example, in manufacturing process, and the line style of the rotational angle of line fork and speed decision finished product; The external diameter change control of cam 15 pushes away the motion of screen frame (unit) 24, decision just pushes away when how many angles screen frame (unit) 24 online forks rotate and promotes the reed curtain, as shown in accompanying drawing 5, when rolling bearing 16 moves to the d point by the e point on shift cam 15, push away screen frame (unit) 24 and open, this moment, the line fork rotated; When rolling bearing 16 moves to the e point by the d point, push away screen frame (unit) 24 and close up, this just determines the density degree of finished product, this process is back and forth carried out with the rotation of axle.

The use of cam 15: when on a face that rolling bearing 16 is pressed in shift cam 15, when pushing away screen frame (unit) 24 online forks and turning over 180 °, promote the reed curtain; When being pressed on the b face, promote the reed curtain when pushing away screen frame (unit) 24 online forks and turning over 360 °; When being pressed on the c face, promote the reed curtain when pushing away screen frame (unit) 24 online forks and turning over 540-720 °, so just realized the control of reed curtain density.

The use of adjustable plate 9: speed change moving tooth mechanism is used to realize the anglec of rotation and the speed of control line fork.When the adjustment hole 18 of the top that crank 13 is sleeved on adjustable plate 9, ball in the locating piece 11 is placed in the locating hole 20 of outmost turns on the gear wheel 7, driven shaft 12 revolutions move a week, dial plate 19 and stir tooth of pinion 8 rotations, under the effect of gear wheel 7 and machine gear 5, rotate 180 ° by chain control line fork; When crank 13 being sleeved on second adjustment hole 18 of adjustable plate 9, ball in the locating piece 11 is placed in the locating hole 20 of second circle of ecto-entad on the gear wheel 7, driven shaft 12 revolutions move a week, dial plate 19 and stir two teeth of pinion 8 rotations, under the effect of gear wheel 7 and machine gear 5, rotate 360 ° by chain control line fork; By parity of reasoning, can realize that the line fork rotates 540 ° and 720 °, forms different line styles.
