Abstract

The utility model relates to a wire feeder which feeds wires through a pair of glue rollers which are longitudinally provided with grooves through the transmission and rolling of a motor and a synchronous belt; wherein one glue roller is arranged on a swing arm and can swing; the most proper clearance between the swing glue roller and another glue roller and a pressure most suitable for a wire beam are adjusted by the swing arm, a jack-prop, a compression spring, a compaction adjusting bolt and a clearance adjusting bolt; moreover, a swing rod is pushed by a poke rod on the swing arm to be capable of triggering an approach switch to alarm during curling round the roller.

Description

Threads feeding apparatus

Technical field

The utility model relates to by feeding the threads feeding apparatus that silk also can be prevented curling round the roll.

Background technology

At present, in carbon fibre precursor is produced, all the coiled spinning cake after precursor is produced, because spinning cake is in transport process, spinning cake two ends sharp corner easily collapse limit and damage, and precursor is a kind of very expensive raw material, so the loss that causes is bigger, unfavorable in production.For overcoming above-mentioned deficiency, now adopted a kind of new technology mode, the method is after precursor is produced, precursor is the coiled spinning cake no longer, but adopts the mode of bucket, and precursor is evenly dropped in the silk bucket, utilize the silk bucket to transport, thereby overcome spinning cake flimsy deficiency in transhipment.But carbon fibre precursor is more tender and lovely, and very easily damage when adopt barrel technology, is fed Si Shiyi and squeezed and hinder fiber and curling round the roll easily.

Summary of the invention

For guaranteeing the enforcement of new process, overcome the unfavorable factor that is produced when adopting this new technology to feed silk, the purpose of this utility model provides a kind of can be guaranteed under new process, the reliable silk of feeding, and do not squeeze and hinder fiber and can prevent curling round the roll, and the threads feeding apparatus of warning can be provided when the contingency curling round the roll.

The technical solution of the utility model is: threads feeding apparatus, pass by driven by motor and synchronous band, two feed roll dies to rolling, by guide chase ring tow is fed to the silk bucket that falls, one of them feeds the roll dies swing, guide chase ring is equipped with in the place ahead of feeding roll dies at wire inlet end, moving rubber roll and rubber roll have the roller of longitudinal groove, and moving rubber roller is contained in the swing arm, and the one side of swing arm is equipped with the top cover, the compression spring is arranged in the cover, link by a fore-set and the adjustment screw that compresses that is contained on the frame, the another side of swing arm is equipped with push rod, and the push rod end face abuts against on the dog screw that is contained on the frame, poke rod is housed in the swing arm, and an end of poke rod is inserted in the groove of a fork.Feed in the silk gum roller for two, have a rubber roll when the contingency curling round the roll, because of tow is entangled on the roller, to be entangled in the tow thickening on the rubber roll around a spot wobble, the rubber roll that promotion can be swung by a test rod that connects firmly in swing arm, touches and reports to the police near switch.

The beneficial effects of the utility model are: can reliably feed silk, not squeeze and hinder fiber, anti-curling round the roll also can be reported to the police when the contingency curling round the roll.

The specific embodiment

Embodiment 1: as shown in Figure 1 and Figure 2, moving rubber roll 2, rubber roll 3 are positioned at the dead ahead of frame 1 side by side, guide chase ring 4 is installed on the guide chase ring support 5, be positioned at the right edge of frame 1, height is parallel with the Up Highway UHW of glue axle 3, tow passes the guide hole of guide chase ring 4, walk around rubber roll 3 and by moving rubber roll 2 under the force feed wire vent; In Fig. 4, rubber roll 3 is contained on the rubber roller 8, and rubber roller 8 is installed on the frame 1 by two square seat ball bearings 16, and left end links by shaft coupling and motor reducer.Synchronous pulley 9 is housed on the rubber roller 8; In Fig. 5, moving rubber roll 2 is contained on the moving rubber roller 15, and moving rubber roller 15 is installed in the swing arm 7 by two square seat ball bearings 16, on the moving rubber roller 15 synchronous pulley 9 is housed, and swing arm 7 hangs on the balance staff 6, and can drive moving rubber roll 2 together around balance staff 6 swings.In Fig. 3, holddown spring 12, fore-set 11 are housed in the lower-left square hole of swing arm 7, the adjustment screw 10 that compresses that is installed on the frame 1 holds out against on the left side of fore-set 11.The bottom-right round lug end face of swing arm 7 abuts against on the dog screw 13 that is loaded on the frame 1, behind the driven by motor rubber roller 8, by synchronous cog belt 14 and 4 synchronous pulley transmissions, makes rubber roll 3 and the reverse synchronous rotational speed of moving rubber roll 2 rotation directions.In Fig. 5, poke rod 17 is housed in the swing arm 7, fork fulcrum 18 is fixed on the frame 1, fork 19 is installed on the fork fulcrum 18 and can swings around fork fulcrum 18, the left end of poke rod 17 is inserted in the groove of fork 19 lower ends, the upper end of fork 19 is close, and the upper end of fork 19 is longer than the lower end near switch 20, thereby the small sway of lower end is reported to the police near switch than the triggering of moving of big distance on can stirring.

Starter motor, pass through Synchronous Belt Drives, moving rubber roll 2, rubber roll 3 be rotation simultaneously oppositely, moving rubber roll 3 is pressed on the rubber roll 2 with the pressure of setting, the groove mutual alignment that vertically has on two rubber rolls be tooth to tooth, groove to groove, tow through guide chase ring 4, walk around rubber roll 3 certain cornerites after the soft roll surface of two rubber rolls is clamped and sent, guaranteed in the reliable undamaged silk bucket that falls of sending into the below of tow, owing to have groove on the rubber roll, reduced the contact length of tow and rubber roll and be interrupted the contact, so be difficult for curling round the roll.

As shown in Figure 3, compress adjustment screw 10,, change the decrement of holddown spring 12, can regulate the pressure that is pressed on the tow, make tow can obtain suitable tractive force through swing arm 7, moving rubber roller 15, moving rubber roll 2 through fore-set 11 by adjustment.Regulate dog screw 13, can make the gap between two rubber rolls obtain best according to the thickness of feeding tow through swing arm 7.

As shown in Figure 5, when moving rubber roll 2 or rubber roll 3 curlings round the roll, because tow twines thickness on roller more and more thicker, thereby promoting moving rubber roll 2 moves to right, make swing arm 7 swings through moving rubber roller 15, promote fork 19, make the upper end of fork 19 close near switch 20 by poke rod 17, when tow is wound into certain thickness, close the arriving in the time of triggering near switch 20 actions in upper end of fork 19 reported to the police.
