Description

Inprovement type electric power-driven doffer

The utility model relates to a kind of modified electro-automatic doffer in the textile machine.

Of the prior art doffing abroad, generally adopts the manipulator imitation manually to doff, its automaticity height, but mechanism's complexity, and the cost height, the speed of doffing is slow, and the yarn that on average whenever falls needs about 4 minutes.Adopt electro-automatic doffer to doff at home, utilize two disks to dial yarn, the defeated pipe of screw rod, Double-edged scissors is cut off yarn, and the yarn tail is around to spindle, and behind the whole end-of-job that doffs, doffer returns automatically.This machine is simple in structure, and cost is low, and group yarn, defeated pipe carry out simultaneously, dial yarn time weak point, but this machine are still perfect inadequately, and be not enough as rigidity, is difficult for assembling and adjusting, and closure is poor, disperses manipulation, electric switch generation spark phenomenon etc.

The purpose of this utility model designs a kind of modified electro-automatic doffer exactly, overcomes above-mentioned defective, makes it more perfect.

Detailed content of the present utility model is described below referring to accompanying drawing:

Doffer of the present utility model is by frame, dial yarn feeding device, defeated cannula device, block yarn feeding device, shear mechanism, transmission mechanism and electric switch constitutes.

Dial yarn feeding device and be made of pre-pine dish (3) and group yarn dish (4), this device installs on the base plate (1), and base plate (1) installs on the frame (2), and frame (2) is the angle steel welding, as depicted in figs. 1 and 2.

Defeated cannula device is by screw rod (5), pipeline (6), (7) and intubate are chewed (8) and constituted up and down, as shown in Figure 3, following pipeline (7) global formation, last pipeline (6) sealing, as shown in Figure 4, strengthened the rigidity of pipeline like this, pipeline is connected by hinge up and down, be convenient to the flexible rotation of pipeline (7) down, intubate is chewed the position of (8) and can be regulated by screw (9), to improve the success rate of intubate, following pipeline (7) is sent by establishing spring mechanism in the hollow cylinder, work finishes, this mechanism position of deactivating, and following pipeline is regained immediately.

Blocking yarn feeding device is to constitute by blocking yarn device and linkage, as shown in Figure 4, yarn blocking rod (10) and fork (12) adopt semi arch to be threaded with spring (11) respectively, and the turnover position of yarn blocking rod (10) can be regulated by screw, be provided with forked link (13) in the linkage, when yarn blocking rod (10) was deactivated the position, rocking bar (14) did not surmount frame (2) outside, and the phenomenon of having avoided the people to hang clothes when the other walking of machine takes place.

Shear mechanism is made of two wheel cut scissors (16), as shown in Figure 1 and Figure 4, every scissors (16) is gone up the fluted disc (15) of having had the guide effect, so that scissors is reliably cut off yarn, the rotation of scissors (16) is to be controlled by belt (17) by the pre-pine dish of dialling in the yarn feeding device (3), dial yarn and stop, scissors also stops operating immediately.

Transmission mechanism is gear drive, and integrally closed.

Electric switch is to be used for connecting power supply, makes complete machine in running order, in be provided with the travel switch that constitutes by static contact and moving contact (21), as shown in Figure 5.Moving contact (21) is controlled by control position bar (22) that it moves, control lever (22) links to each other with tooth bar (20), its position is regulated by screw (23), tooth bar (20) is meshed with sector gear (19) on the handle (18), turning handle (18), outer contact (24) immediately with power connection, by the transmission of gear (19) with tooth bar (20), driving control position bar (22) moves forward, behind control position bar (22) the contact moving contact (21), drive moving contact (21) and move forward together, thereby it is contacted with static contact, entire circuit is connected.Travel switch has avoided outer contact (24) to connect power supply, and entire circuit is connected at once, and contact (24) is gone up the spark phenomenon that takes place outside, has prevented the danger in the cotton mill breaking out of fire.

In addition, the manipulation of electric switch and group yarn feeding device is centralized control, as long as the workman stands in the operating position, and order control crank (25), (18), can carry out work, bring convenience to the workman, as shown in Figure 6, simultaneously, complete machine is except that dialling the yarn part, the complete machine sealing has not only reduced the intrusion of dust, and has beautified the outward appearance of complete machine.

Not only cost is low for modified doffer of the present utility model, and the speed of doffing is fast, and approximately speed is per 50 seconds, 204 ingots, and good rigidity, not yielding in the transportation, simple in structure, operation, easy to adjust, electric switch is safe and reliable, gear drive sealing, during outage, but also hand push doff, intubate, simultaneously, this machine closure is good, and good looking appearance is a kind of fairly perfect electro-automatic doffer.
