Description

The improved structure of slide fastener make-up machine pay-off

Technical field

The utility model is the improved structure of relevant a kind of slide fastener make-up machine pay-off, refers to a kind of wire frame outer rim of utilizing especially as touch surface, and increases the line sending stability of slide fastener make-up machine pay-off, and effectively improves the dimensional accuracy of slide fastener moulding.

Background technology

Press, slide fastener make-up machine pay-off is after slide fastener monofilament bobbin feeding a period of time, its external diameter will have the gesture of dwindling gradually because of the minimizing of silk amount, and the big volume state of the little volume state of its yarn angle when reduced diameter during with full yarn has great difference, the slide fastener compact dimensions inequality when this will cause large and small volume state; And when shutting down, the monofilament bobbin forms idle running, and the problem that the monofilament of deriving gets loose when starting shooting as going under the situation that gets loose at monofilament, has the situation of fracture of wire often again, not only increases operational trouble, and will improve the fraction defective of slide fastener finished product.

Moreover, because monofilament is to be wound on the monofilament bobbin with the reciprocating type translation in the left and right sides, the monofilament winding is not even up and down proper alignment on bobbin, but the high and low is fluctuated, constantly beat, therefore, pay-off is when the monofilament bobbin is pulled out monofilament, and the yarn path of monofilament is the mode that swings that is about height, the situation that this will cause the monofilament bobbin constantly to be beated, and then the stability that influences yarn is to hard iron.

For this reason, the improved structure of one slide fastener make-up machine pay-off commonly used is arranged, and it is with behind a counterweight sail bag 1 ccontaining several balancing weights 2, directly contacts on the coil 3 and reaches, and be the below that is hung on wire frame fixed mount 5, on the board 4 of slide fastener make-up machine and set up wire frame 6; When carrying out the line sending operation when wire frame 6 rotations, canvas bag 1 can suppressing coil 3 makes its stable line sending by the weight of balancing weight 2, and is extremely shown in Figure 1 as Fig. 1.

Only, this dust head, as if being touch surface with coil 3, then because the winding uniformity of line body 3a is limited, therefore, beating of dimensional tolerance is interval big; In addition the wheel of the winding portion of coil 3 footpath may justify inadequately, and therefore, line sending speed also has unsettled phenomenon; In addition because the external diameter of coil 3 can successively decrease with line sending speed, therefore, when coil 3 external diameters gradually hour, line sending speed is not a stationary value; Be with, to the greatest extent desirable yet in the practicality.

Moreover, when the line material of coil 3 more after a little while, the influence of inertia phenomena is bigger, therefore, line sending speed has unsettled phenomenon; And the winding tension of general coil 3 differs, and its tightness is different, and then counterweight sail bag 1 will make the slack strand of coil 3 progressively be accumulate to opposite side, and then may cause phenomenon such as be entangled with, break, come off, as shown in figure 13.

Summary of the invention

Edge this, this creator is because of because the desirable part to the greatest extent that all still has commonly used, actively design and actual tests develop the improved structure that the utility model slide fastener make-up machine pay-off that can significantly promote practical effect, then with the demand in response to reality.

Main purpose of the present utility model, be the improved structure that a kind of slide fastener make-up machine pay-off is provided, be to utilize the touch surface of the wire frame outer rim of slide fastener make-up machine as the line sending stabilising arrangement, and by a telescopic unit, make guide wheel can be pressed on the outer rim of wire frame, use intermarginal formation one compacting elastic force outside guide wheel and wire frame, and make line sending speed more stable.

An of the present utility model purpose promptly is to provide a kind of improved structure of slide fastener make-up machine pay-off; it also can be by a spring pressure device; effectively adjust the pressure state of monofilament bobbin when large and small volume state; yarn angle with homogenizing monofilament bobbin; and the phenomenon that gets loose of the monofilament tension force in the time of can preventing to shut down, and further improve the dimensional accuracy of slide fastener moulding.

The utility model is further created the improved structure that purpose promptly is to provide a kind of slide fastener make-up machine pay-off, it is can sending in the yarn path in wire frame and quantitative feed between centers, further be provided with one and stablize pay-off, use suppress monofilament because of about swing the jumping phenomena that the yarn path is caused, and keep a stable yarn speed, and further promote the dimensional accuracy of slide fastener moulding.

The utility model is in order to reach above-mentioned purpose and effect, and the technological means that it adopted comprises:

A kind of improved structure of slide fastener make-up machine pay-off be with the touch surface of wire frame outer rim as the line sending stabilising arrangement, and this line sending stabilising arrangement comprises again:

Should illustrate around here, the utility model can be in sending the yarn path, but further be provided with the guide pin bushing 99 of a left and right sides slippage, after then single line 51 is drawn, after can passing guide pin bushing 99 earlier, enter quantitative feed axle 70 again, and deliver to (quantitative feed axle 70 and rotary disc feeder 71 in the rotary disc feeder 71, be found in the separate case that the utility model people before filed an application, hold and do not give unnecessary details), because guide pin bushing 99 can be gone up left and right sides slippage freely in beam barrel 99A, thus can subdue because of single line 51 vibration that move left and right produced on wire frame 50, and reduce the factor that influences formed precision.

To shown in Figure 10, in the 3rd embodiment, the utility model can further be provided with one and stablize pay-off 90 in the sending in the yarn path of 70 on wire frame 50 and quantitative feed axle as Fig. 7; As shown in the figure:

Should stablize pay-off 90, be to stablize axle 96, an Extendible flake 97, reach an insulator 98 etc. and constituted by a firm banking 91, two bearings 92,93; And two bearings 92,93 is fixedly arranged on respectively on two

side shaft holders

94,95 of firm banking 91, wears for stablizing

axle

96, and 97 of Extendible flakes can be provided with an insulator 98 and be fixed on the bearing block 95;

By this, make monofilament 51 before entering quantitative feed axle 70, can pass insulator 98 earlier, and can be in stablizing on the axle 96 around a few, and suppress monofilament 51 because of about swing the jumping phenomena that the yarn path is caused, keeping a stable yarn speed, and further promote the dimensional accuracy of slide fastener moulding.
