Abstract

The utility model relates to a mechanical differential-phase regulating device. A differential gear train is arranged on a driven gear and forms a 2K-H type planet gear train by conical gears, a planet gear and a train rod H. One of half shafts of two conical gears is connected with a driving device, and the other half shaft is connected with a regulating handle. Though adopting the pure mechanical device to manually regulate, the utility model has simple structure and can omit a DC motor and an electric control system. When the deviation of phase occurs, the mechanical differential-phase regulating device can realize non-step speed change under the condition of not stopping the device and having loads, and has the advantages of convenient and simple operation and good regulating effect. The utility model can be widely used for various occasions which need regulating the phase of work pieces, such as food industries, packing industries, printing industries, etc.

Description

The differential phase adjusting apparatus of mechanical type

The utility model relates to the phase adjusting apparatus that mechanical transmission is coordinated mutually, particularly a kind of mechanical type differential gear train phase adjusting apparatus

At present in industries such as food package, printing; because machine error, transmission cumulative error, line belt and be transmitted between thing factor such as adhesion deficiency; cause production line respectively to cooperate and transmit phase place generation deviation between workpiece; can not form acceptable product; thereby need often to shut down to adjust, influence the continuity of producing greatly.With existing apple bag automatic moulding machine is example, and this machine comprises that outer bag launches processing mechanism, inner bag shaping operation mechanism and folding sleeve forming processing mechanism three parts.Its outer bag development mechanism and inner bag former block by dc speed-regulating motor by speed reducer and chain drive.Owing between above-mentioned various errors and inside and outside bag body paper and the take off roll relative displacement is arranged, has a strong impact on the accuracy that overlaps when inside and outside bag folding overlaps.The measure of adjusting phase place at present mainly contains two kinds, and a kind of is to shut down jiggering, though this method need not increase equipment, and troublesome poeration, labor intensity is big, and holding time is many, continuity and manufacturing efficiency that influence is produced.Another kind is electrical control, adopts electronic technology or the automatic control phase of other Comprehensive Control Technology.This method need adopt two synchronous machines to drive respectively, must increase corresponding deceleration system and electric control system, though can improve automatization level, the equipment complexity costs an arm and a leg, and is difficult to adopt with medium-sized and small enterprises on the general device.

The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, and provides a kind of simple in structure, can not shut down the mechanical type phase adjusting apparatus of adjusting line speed under the on-load state.

Solution of the present utility model comprises driving gear and driven gear, it is characterized in that on driven gear, being provided with a differential gear train, this differential gear train is formed 2K-H type epicyclic gear train by two cone gears and planet wheel and tie-rod H, and tie-rod H and driven gear are fixed to be one; The center that the semiaxis of a cone gear passes driven gear is used for drive transmission; The semiaxis of another cone gear links to each other with handle.

The semiaxis of above-mentioned cone gear can link to each other with handle through worm gear, worm screw.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural scheme of mechanism of apple bag differential phae regulating device.

Referring to accompanying drawing, motor 10 drives driven gear 2 through driving gear 1.Gear 1 and gear 2 are fixed shaft gear trains.Motor drives outer bag transmission device 12 work with fixed drive ratio.The

transmission device

12,13 that needs control phase can be apple bag-shaping machine or other similar means.Two transmission devices are pressed direction of arrow relative movement among the figure.On driven gear 2, be provided with a differential gear train 8.With the fixed

cone gear

4,5 of two

semiaxis

14,15 and planet wheel 3,3 ' and and the tie-rod H of gear 2 fixed one form a 2K-H type differential gear train.In this differential gear train, when in three basic building blocks during given wherein two speed drive shaft, the rotating speed of its driven shaft is the synthetic of two driving shaft rotating speeds.Because the semiaxis 14 of gear 4 is driven by worm gear 6, and worm gear, worm screw have self-locking performance, promptly can only drive worm gear by worm screw, and can not be by the worm gear drives worm screw.Like this, gear 4 keeps motionless under the self-locking action of worm gear during proper functioning.Cone gear 5 drives 13 work of apple inner bag transmission device by planet wheel 3 driven rotary through semiaxis 15.At this moment, differential gear train fixedly becomes planetary gear train because of a central gear.When inside and outside bag transmission device phase difference occurs and need adjust, drive cone gear 4 rotations by handle 11, worm screw 7, worm gear 6 and semiaxis 14, at this moment the rotating speed of driven shaft 15 is that two driving shafts are the synthetic of tie-rod H and semiaxis 14 rotating speeds, shakes handle and can make driven half shaft 15 realize stepless change under the on-load state.The increase and decrease of its speed can realize by the direction that handle 11 changes the worm gear rotation.Here, handle 11 also can adopt motor, oil cylinder, gear, tooth bar or other electric executive component control, all belongs to protection domain of the present utility model.

The utility model compared with prior art has following advantage:

1 adopts pure mechanical device manually to adjust, simple in structure, can save traditional direct current generator and complicated Electric control system makes the cost of equipment decrease.

2. when the workpiece phase generate deviation that cooperatively interacts, can do not shut down realize under the on-load state electrodeless Speed change, simple to operation, adjust effective.

3. except the apple make-up machine, also can be widely used in needing to adjust the various occasions of phase place between workpiece, such as food In all conglomeraties such as product, packing and printing.
