Abstract
A self-locking bidirectional clutch comprises a driving shaft linked with a transmission shaft of a soft packing machine and a driving wheel arranged on the driving shaft, and is characterized in that the driving wheel is at least provided with two radial grooves, springs and pawls are arranged in the grooves, an internal tooth type ratchet wheel is arranged outside the driving wheel, and the ratchet wheel is controlled by an electromagnetic braking device of the soft packing machine. The advantages are that: the feeding precision is high, no error exists, the feeding device is durable, money and labor are saved, the feeding is reliable, and the phenomenon of slipping does not occur.
Description
The utility model relates to the self locking type bidirectional clutch that a kind of soft-packaged machine film feeding mechanism is used.
Twin-direction clutch on the former flexible package axle is the electromagnetic type twin-direction clutch, utilize position limit switch control power on/off, make magnetic clutch adhesive or disconnection, the magnetic clutch adhesive of energising back, frictional force by two face friction plates is come transmitting torque, the every counterclockwise rotation hexagonal angle of clutch degree draws a gage length with flexible packaging film, and the can envelope is cut into type then.It is very strict that the weight of soft packing food requires, so the length of the package bag of leaving behind must be consistent at every turn.A former new electromagnetism twin-direction clutch used less than two months, and the two sides friction plate so just causes the transmission skidding with regard to serious wear, make the package bag size of at every turn leaving behind uneven, reject rate increases, and has encroached on Consumer's interests, has also influenced the reputation of manufacturer.
The purpose of this utility model provide a kind of new structure with the matching used self locking type bidirectional clutch of soft-packaged machine, it can overcome existing shortcoming in the prior art.
The purpose of this utility model is achieved in that the self-locking clutch comprises with the driving shaft of soft-packaged machine transmission shaft interlock and is installed in driving wheel on the driving shaft, it is characterized in that driving wheel has two radial grooves at least, spring and ratchet are housed in the groove, driving wheel is equipped with the internal gear type ratchet outward, and ratchet is by the electro-magnetic braking device control of soft-packaged machine.Electro-magnetic braking device is to be controlled by position limit switch when at self locking type bidirectional clutch counterclockwise rotation 120 degree angles packing film being drawn next gage length, the ratchet of self locking type bidirectional clutch is held, make it can not about, when the positive hour hands of the driving wheel of self locking type bidirectional clutch go back to 120 degree angles, electro-magnetic braking device is opened at once, makes the self locking type bidirectional clutch successfully carry out film feeding next time.
Characteristics of the present utility model are: 1, feed accuracy height does not have error; 2, durable in use, it is laborsaving to save money; 3, feeding does not reliably have skidding.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Fig. 2 is the side view of Fig. 1.
Self locking type bidirectional clutch packing driving shaft 1 and be installed in driving wheel 2 on the driving shaft, driving shaft 1 links by the rotating shaft on chain and the wrapping machine, when the 2 positive hour hands commentaries on classics 120 of driving shaft 1 drive driving wheel are spent, just turning in the journey of 120 degree, ratchet 5 is braked by electromagnet, under the pressure of ratchet 5 helical teeth, four ratchets, 4 pressure springs 3 on the driving wheel slip over 120 degree angles to clockwise direction, four ratchets 4 on the driving wheel are according to the calibration of science, zero-bit is spent in each revolution 120 all has 1-2 ratchet to stop so just having guaranteed the sack unanimity of at every turn leaving behind at the bottom of some teeth of ratchet.When driving wheel counter-rotating 120 was spent, the electromagnetic braking outage stopped braking, and driving wheel draws next length with ratchet 5 counterclockwise rotations 120 degree with film by ratchet 4, the can involution, circulation makes the soft wrapping bag length unanimity that at every turn goes out repeatedly, can not produce big pouch phenomenon because of cltuch slipping.
