Description

The head feeder cart device that is used for band rewinding and rip cutting manufacturing line

The utility model is a kind of head feeder cart device that is used for band rewinding and rip cutting manufacturing line, and specifically it is to pinch to take the lead and the device of magnetic tape trailer by kink hole in the manufacturing line.

In prior art, the band rewinding is mainly used in side cut or the rip cutting of finishing band with the rip cutting manufacturing line and becomes many arrowbands and be rolled into the work that finished product is rolled up.At present, the manufacturing line of domestic public use as shown in Figure 4, it is mainly deposited platform 1, skip car 2, decoiling unit 3, beginning straightener 4, crop shears 5, upright deflector roll 6, circle shear 7, kink hole 8, send a dolly 9, tension force pressing plate 10, inspecting stand 11, feeding roller 12, is cut and cut 13, slewing rollers 14, reeler 15, unload volume car 16, products storage platform 17, folding-and-seaming press 18 and form by blank.During this manufacturing line work, earlier will leave blank in by skip car 2 deposits on the blank on the platform 1 to decoiling unit 3, after the decoiling unit work, to take the lead to send into the beginning straightener, and arrive crop shears 5 through the aligning back, crop shears will take the lead to cut away, arrive circle shear 7 through upright deflector roll 6 forward again then, circle shear cuts away the blank longitudinal edge or the blank rip cutting is become many required arrowbands, thereby finishes the side cut and the rip cutting operation of blank, and wherein side crops is rolled by folding-and-seaming press 18.Be provided with a kink and cheat 8 after circle shear, band forms a kink by this kink hole the time, can make the feeding speed of front and back, kink hole that bigger setting range is arranged like this.The described dolly 9 that send will will be taken the lead or magnetic tape trailer sent kink hole, delivers to feeding roller 12 by tension force pressing plate 10 and inspecting stand 11 always, and then then forward by feeding roller 12, cut 13 by cutting, slewing rollers 14 deliver to reeler 15, carry out batching of finished product volume by reeler, when the diameter that batches reaches requirement, cut to cut band is cut off, the finished product volume is unloaded by dummy car 16, deposits on the products storage platform.At present, send a dolly to draw by two chains to walk in this manufacturing line, this traveling gear is difficult for making the tractive force of both sides to reach in full accord, makes dolly occur crooked in walking and derailment occurring takes place; Moreover, adopt the electromagnetic clamp plate holder to hold on the dolly and take the lead, need manually switch on and power operation, make operation inconvenience.

The purpose of this utility model is at derailing in the prior art and unhandy problem, and a kind of improved head feeder cart device that is used for band rewinding and rip cutting manufacturing line is provided.

For achieving the above object, solution of the present utility model is as follows: it comprises the traveling gear and the walking driver train of the one pair of guide rail that is located at this place, manufacturing line kink hole, the dolly of walking, dolly on guide rail, its key structure is: described carriage walking mechanism is made up of a pair of drive sprocket or the gear that are laid on chain or tooth bar on the guide rail, are located on the dolly and are meshed with chain or tooth bar on the guide rail, and described carriage walking driver train and described drive sprocket or gear wheel shaft link; Described guide rail is the channel-section steel structure, and the road wheel of dolly is positioned at the groove of channel-section steel guide rail; Also be provided with a pinch roll mechanism on dolly, this pinch roll mechanism comprises the pinch roll frame that is located on the dolly, be located at a pair of pinch roll on the frame, be located at separate roller before the pinch roll, be located at the hoist cylinder of pinch roll top, the feeding driver train that is located at a side of pinch roll constitutes.

By above-mentioned solution as can be seen, walking on chain or tooth bar has reached dolly both sides driving equilibrium of forces to the utility model with a pair of drive sprocket or gear, simultaneously, the version that has also adopted the road wheel of dolly to walk in the groove of channel-section steel guide rail has prevented the generation of derailment occurring effectively.Have, this carriage device adopts the pinch roll mechanisms grip to take the lead again, and after will taking the lead to send the kink hole, again by pinch roll feeding forward, these are operated with the realization of pressing a button, thereby have overcome unhandy shortcoming.

Describe structure of the present utility model and principle of work in detail according to embodiment below.

Fig. 1, integral structure scheme drawing of the present utility model.

Fig. 2, plan structure scheme drawing of the present utility model.

The constructional drawing of Fig. 3, parallelism adjusting pad.

The work scheme drawing of Fig. 4, band rewinding and rip cutting manufacturing line.

Referring to Fig. 1,2, sequence number 20 is described one pair of guide rail bracket, and it adopts the channel-section steel structure, and is located at the bank, both sides in kink hole 8; The 21st, the dolly car body is provided with two pairs of road wheels 22 on this car body, and this road wheel is along walking in the groove of channel-section steel guide rail.On described guide rail 20, also laid one pair of chain 23, and on dolly a pair of and chain 23 ingear drive sprockets 24, the driver train of dolly is made of motor 25 and cycloidal planetary gear speed reducer 26, and this reductor links by the type of drive of sprocket wheel and chain and the wheel shaft 27 of dolly drive sprocket.When motor 25 work, drive sprocket wheels 24 by retarder 26 and rotate, thereby driving trolley move along guide rail, the forward and backward of control motor can make dolly crank motion on guide rail.The described pinch roll mechanism that is located on the dolly is made of frame 28, pinch roll 29, separate roller 30, hoist cylinder 31, feeding driver train 32,33.Wherein pinch roll is installed on the frame 28 by bearing seat, and the bearing seat of top roll drives lifting by oil cylinder 31, realizes the adjustment of upper and lower roll spacing; Lower roll is driven by the feeding driver train, realizes pinching band, and the feeding driver train is made of motor 32 and worm reduction gear 33.Be respectively equipped with guide plate 34,35 in the front and back of separate roller and pinch roll, take the lead to arrive separate rollers,, forward again after the taking the lead of a plurality of arrowbands will separate by separate roller if band is become a plurality of arrowbands by rip cutting by guide plate 34; If band is just cut edge, need taking down on the separate roller every dish.

For the spacing between the upper and lower roll two ends is equated, prevent the feeding sideslip, between the bearing seat at the two ends of upper and lower roll, be respectively equipped with a parallelism adjusting pad 36.Referring to Fig. 3, this adjusting pad by screw bolt seat 36-1, be spun on the screw rod 36-2 in the screw bolt seat, the clamp nut 36-3 that is spun on the screw rod and constitute.The turn screw rod makes its upper and lower moving, and the spacing at upper and lower roll two ends is adjusted to consistent location, fixes with clamp nut again, thus the adjustment of realization upper and lower roll parallelism.
