Embodiment

As shown in Figures 1 to 4, the planetary crankshaft gear of the utility model comprises inner rotary table 3, outer rotary table 5, is provided with a plurality of bent axles 4 between inner rotary table 3 and the outer rotary table 5, and an end of bent axle 4 flexibly connects by inner rotary table bearing and inner rotary table 3; The other end of bent axle 4 is fixedlyed connected with outer rotary table 5 by the outer rotary table bearing, and this end of bent axle 4 connects one or more guide grooves 6, and guide groove 6 is used for support or transmits bar-shaped material.Four guide grooves 6 among Fig. 1, Fig. 3 can be provided with more guide groove 6 as required with respect to outer rotary table 5 circumference uniform distributions, and guide groove 6 can be not uniform with respect to outer rotary table 5 yet.

Guide groove 6 is provided with negative pressure hole or holds the cutter groove.

The gyration center 9 of outer rotary table 5 departs from the gyration center 8 of inner rotary table 3.There is angle theta between the gyration center line of the center line of bent axle 4 and inner rotary table 3.

The gyration center 9 of outer rotary table 5 is vertical distribution or horizontal distribution with the gyration center 8 of inner rotary table 3.As shown in Figure 1, the gyration center 9 of outer rotary table 5 is positioned at the top of the gyration center 8 of inner rotary table 3; As shown in Figure 3, the gyration center 9 of outer rotary table 5 is positioned at the left side of the gyration center 8 of inner rotary table 3.Inner rotary table 3 is connected the location by bearing with bearing support 2, and live axle 1 passes bearing support 2 and is connected with outer rotary table 5.

When the utility model was used for the support material, the guide groove 6 of bent axle 4 one ends was used for the bar-shaped material of support as reciprocating loudspeaker mouth.

When the utility model is used to transmit material, the guide groove 6 of bent axle 4 one ends is as spider hand or poking wheel, to indulge (axle) and directly become the motion that rotates in a circumferential direction to straight-line bar-shaped material, the bar-shaped material of the motion that perhaps will rotate in a circumferential direction directly becomes linear longitudinal movement.

During work, live axle 1 drives outer rotary table 5 rotations, makes bent axle 4 around 9 rotations (revolution) of the center of outer rotary table 5, and bent axle 4 and then drive inner rotary table 3 be 12 rotations in the counterclockwise direction around its center 8; Meanwhile, bent axle 4 is that 360 ° of rotations (rotation) are done around the one end in the center of circle with the inner rotary table bearing.Because bent axle 4 carries out rotation in revolution, bent axle 4 drives the guide groove 6 that is attached thereto and does planetary motion, makes guide groove 6 realize the regular motion of speed-controllable.

As shown in Figure 1 and Figure 2, continuous bar-shaped material 10 is along directly in 11 movement processes, and bar-shaped material 10 is by guide groove 6 supports, and by the cutting knife 7 of rotation along dividing otch 13 to cut, to obtain to meet the segmentation bar of technological requirement.

Guide groove 6 is done and is kept its opening direction constant in the planetary motion process, and promptly guide groove 6 parallel moving make guide groove 6 maintenance levels in the course of the work.

The utility model is compared with the rotation holder cigarette guide apparatus of planetary pinion transmission, do not need complicated gear transmission structure part and follow gear transmission and the lubricant method established, structure is simpler, keep in repair convenient, except bearing, do not have the contact friction between metal and the metal, thereby do not need to consider in addition that oil (fat) is lubricated.Comparing its robust motion with the to-and-fro motion crank connecting rod apparatus has improvement greatly, can not produce tangible motion noise, vibration and superheating phenomenon in the high-speed motion process.

As shown in Figure 1 and Figure 2, guide groove 6 of the present utility model is provided with when holding the cutter groove, can be used as rotation holder cigarette guide apparatus, be used for YJ19A type cigarette machine, substitute two of its planetary pinion transmission or three holder cigarette guide apparatus, in the cutting process of cutting device, play a supportive role the continuous plume of axial motion.The cutting knife cutting used time of plume is of short duration, also is relatively-stationary, thereby holder cigarette guide groove only need be synchronized with the movement with cutting knife and put in place, and supports plume and can achieve the goal in of short duration cutting process.The utility model also can be used for ZJ15 type rolling connection unit, ZJ17 type rolling connection unit, ZL22 type shaping machine set, ZL26 type shaping machine set etc.Appearance cutter groove is used for cutting knife and passes through so that cut off material.

As shown in Figure 3, Figure 4, when guide groove 6 of the present utility model is provided with negative pressure hole, can be used as the handing-over wheel apparatus, be used for cigarette machine and filter-stick forming device, can receive one by one and hand in the drum groove that rotates and reprocess continue to do the cigarette of axial linear movement or filter stick after cutting through cutting device.In this process, the moving direction of cigarette or filter stick acquires change---and become the motion that rotates in a circumferential direction by axial linear movement, and hand or transmit the position over to accurately and reliably.Perhaps the combined filter that rotates in the drum groove is pursued and processes again, the moving direction of combined filter is acquired change handing on the opium pipe track after receiving---motion becomes axial linear movement by rotating in a circumferential direction.Negative pressure hole can receive (absorption) or transfer (release) material in certain zone, realize the material transmission.

The utility model can be applied to also that rolling connection unit and filter stick formation unit etc. are similar to be needed support or transmit in the mechanism of bar-shaped material, as ZL41 type composite filter shaping machine set, ZJ15 type rolling connection unit, ZJ17 type rolling connection unit, ZJ19A type rolling connection unit, ZL22 type shaping machine set, ZL26 type shaping machine set etc.It is not accurate enough that the utility model has been eliminated transmission, obstruction, and complex structure easily, heating and the shortcoming that need lubricate especially.
