Description

Bobbin-winding machine anti-overlapping planet gear differential mechanism

Technical field

The utility model relates to a kind of parts of bobbin-winding machine, particularly a kind of anti-overlapping device.

Background technology

In existing bobbin-winding machine, for prevent that yarn from overlapping in the winding process on the yarn tube, be provided with the corresponding structure measure, a kind of structure is to drive roller and groove drum respectively by two groups of servomotors, by control to two servomotors, liken to according to predetermined transmission in the groove of groove drum for guide wire and to move back and forth, be groove drum whenever turn around (360 °), guide wire is difference one predetermined angular value (as 10 °) in a unidirectional total travel, to realize preventing overlapping effect in the yarn additive process, and then get back to original position by predetermined value (as groove drum rotation 30 circles), repeat down the on-cycle operating process again, though said structure can realize preventing the yarn overlapping function, but two groups of driven by servomotor make structure greatly complicated, and in order to guarantee accurate transmitting ratio to keep its anti-overlapping function, must adopt the servomotor and the corresponding kit of function admirable, its price certain hour is very expensive, thereby equipment cost is obviously increased; Another kind of electronic type anti-overlapping structure, promptly frequent switch motor, its advantage is simple in structure, and shortcoming is that the coefficient of its anti-overlapping is a fuzzy quantity, easily produces anti-overlapping and loses efficacy, and therefore its applicable scope also is subjected to very big restriction in addition.

The utility model content:

Technical problem to be solved in the utility model is, a kind of bobbin-winding machine anti-overlapping planet gear differential mechanism is provided, and its can simplified apparatus structure, reduces equipment cost, and reliable, applied widely.

The technical scheme in the invention for solving the above technical problem is: an electrical motor drives respectively through a drive belt and connects a roller drive pulley and a groove drum drive pulley, is characterized in being bearing fit on the transmission shaft of the sheathed fixed conveyor at one end of groove drum belt pulley; Be connected at the other end of transmission shaft and the input end of sun and planet gear; The mouth of sun and planet gear is connected with groove drum.During work, electrical motor drives transmission shaft and roller simultaneously, and transmission shaft is through planetary gear construction driven rotary groove drum, and groove drum whenever turns around and transmission shaft difference one predetermined angular thereby form, and realizes preventing overlapping effect.

The utility model drives roller and groove drum simultaneously with a common electric machine, the structure of equipment is obviously simplified, and common electric machine and servomotor are relatively, the price difference of its separate unit is also very big, even make entire equipment under the condition that increases the number gear part, cost also can reduce greatly, and set member can guarantee the equipment reliability service, guarantee the reliability of anti-overlapping, can be suitable for various yarns, enlarge its Applicable scope.

The specific embodiment:

The utility model is driven respectively simultaneously through a driving band (as flat belt, cone belt, cog belt etc.) by a common motor and connects a roller drive pulley and a groove drum drive pulley, its middle roller drive pulley is captiveed joint with roller, groove drum drive pulley 4 is captiveed joint with transmission shaft 3, when being the electrical motor rotation, can drive roller and transmission shaft 3 rotations simultaneously; Groove drum 2, be a cylindrical body, cylindrical shell 21 is provided with can be for the groove 22 of guide wire slippage thereon, its structure is identical with conventional confguration, be provided with muscle in the cylindrical shell 21 and connect a hub portion, hub portion is provided with through hole, and this through hole can be set on the transmission shaft 3 and be bearing fit, be provided with the accentric rib in cylindrical shell 21, rib is provided with eccentric orfice (23).

The other end of drive pulley 4 is installed at transmission shaft 3, be provided with a planet gear structure 1, planetary gear construction 1 includes miniature gears 11, idle pulley 12, sun wheel 13, satellite gear 14, pinion carrier 15, connecting rod 16, fork 17 and bearing pin 18, shown in Fig. 1,2,3,4,5,6, wherein:

Miniature gears 11 is input ends of sun and planet gear 1, and miniature gears 11 is installed in transmission shaft 3 (shown in Figure 1 is to connect with pin, also can adopt other captive joint type of drive), miniature gears 11 and idle pulley 12 engagements;

Idle pulley 12, endoporus and anchor shaft 121 are slip (or rolling) and cooperate, and anchor shaft 121 1 ends are fixed on the housing, the big width of idle pulley 12 tools, one side and miniature gears 11 engagements, opposite side and sun wheel 13 engagements;

Sun wheel 13, its endoporus and transmission shaft 3 are bearing fit, can do freely to rotate sun wheel 13 and satellite gear 14 engagements on transmission shaft;

Satellite gear 14 is tape spool formula structures (as shown in Figure 4), and promptly the side extension one at gear has a shaft extension 140, and the stomidium 150 that this shaft extension 140 is extended through pinion carrier 15 is bearing fit;

Pinion carrier 15, shown in Fig. 3,5, its frame end is provided with a stomidium 150, and its middle part is provided with a centre hole 151, and centre hole 151 is set on the transmission shaft 3, fixes with pin (as shown in Figure 1) or similar other members, and promptly pinion carrier 15 and transmission shaft 3 are unitary rotation;
