Description
Technical field
The utility model belongs to large circle machine field, relates to a kind of drawing and winding device of large circle machine in particular.
Background technology
Knitting machine utilizes knitting needle that the yarn of various raw material and kind is formed coil, connects into a kind of Weaving device of the technical process of knitted fabric again through string cover.And large circle machine is common a kind of circular knitter, the cloth that existing large circle machine is produced generally carries out rolling by winding up roller, and its cloth is easily wrinkling thus affect the quality of yardage roll in wrapup procedure.
The Chinese patent of application number position 201420469932.6 discloses the cloth retracting device on a kind of large circle machine, comprise two supporting bases, crossbeam and pressure pin, crossbeam is positioned at the downside of pressure pin, the two ends of crossbeam are separately fixed on two supporting bases, the two ends of pressure pin are hinged on two supporting bases respectively, the both sides of pressure pin are respectively by there being retracting roller, the supporting base of pressure pin both sides forms respectively the gathering sill of arc, the gathering sill that the two ends of retracting roller are each passed through two supporting bases is hinged on the middle part of connecting rod, the lower end of connecting rod is hinged on supporting base, top forms driving lever, driving lever is fixed with switch on the supporting base of side, supporting base sideline.The Scroll that it adopts by tension be pressed against with pressure pin on thus make to limit by the yardage roll in wrapup procedure, prevent yardage roll wrinkling, but cloth needed through tensioning apparatus before entering wrap-up, there is fold because each several part tension force is uneven in cloth between tensioning apparatus to Scroll, even if be so subject to the extruding of pressure pin, cloth is still buckle condition.
Utility model content
For the deficiencies in the prior art, the utility model provides one and can launch cloth, make cloth be wound on Scroll before fully stretch, prevent fold, and then avoid the cloth generation fold that is wound on Scroll and affect the drawing and winding device of the large circle machine of cloth quality.
For achieving the above object, the utility model provides following technical scheme: a kind of drawing and winding device of large circle machine, comprise two supporting bases, Scroll is provided with between two supporting bases, spread roller is also provided with between described two supporting bases, the surface of described spread roller is provided with the contrary helical raised of the hand of spiral by middle part to two ends, and described spread roller and Scroll are all connected with motor.
Further described spread roller is provided with two, and the line of described two spread rollers and Scroll side is triangular in shape.
Further described spread roller is that hollow is arranged, and described helical raised and spread roller surface form helical groove, described helical groove offer penetrating the first wind inlet to spread roller inside.
Further be provided with aspiration channel between described two supporting bases, described aspiration channel is positioned at spread roller hollow space, and the cross section of aspiration channel is fan-shaped, the cambered surface of described aspiration channel offers the second wind inlet.
Aspiration channel further in described two spread rollers is connected with an induced-draught fan jointly.
Compared with prior art, the beneficial effects of the utility model are: two spread rollers walked around successively by cloth, and make cloth between two spread rollers in " S " shape, finally be wound on Scroll, when Scroll is reeled to cloth by driven by motor, first cloth will pass through spread roller, helical raised reverse on spread roller will carry out launching to both sides to cloth rapidly, cloth is made no longer to have fold, cloth walks around spread roller in " S " shape, increase the contact area of spread roller and cloth, namely spread roller is strengthened to the expansion effect of cloth, simultaneously by the air draught of induced-draught fan, make to form negative pressure in the first wind inlet, the fine hair of cloth surface is removed, make cloth cleaner, avoid fine hair fly and affect the operation of equipment everywhere simultaneously.

Reference numeral: 1, supporting base; 2, motor; 3, induced-draught fan; 5, Scroll; 6, spread roller; 61, helical raised; 62, groove; 63, the first wind inlet; 7, aspiration channel; 8, cloth.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the embodiment of the drawing and winding device of the utility model large circle machine is described further.
A kind of drawing and winding device of large circle machine, comprise two supporting bases 1, Scroll 5 is provided with between two supporting bases 1, spread roller 6 is also provided with between described two supporting bases 1, the surface of described spread roller 6 is provided with the contrary helical raised of the hand of spiral 61 by middle part to two ends, and described spread roller 6 and Scroll 5 are all connected with motor 2.
When using, spread roller 6 and Scroll 5 rotate simultaneously, and the linear velocity of spread roller 6 is greater than the linear velocity of Scroll 5, by the surface of knitting good cloth 8 by spread roller 6, then be wound on Scroll 5, along with the rotation of Scroll 5, cloth 8 is wound on Scroll 5, meanwhile, first cloth 8 need by spread roller 6, the reverse helical raised 61 that spread roller 6 surface is arranged rotates being greater than under cloth 8 transfer rate, cloth 8 will be made fast to launch, even if cloth 8 has fold, also will be launched by helical raised 61, avoid the cloth 8 be wound on Scroll 5 that fold occurs.
The preferred described spread roller 6 of the present embodiment is provided with two, the line of described two spread rollers 6 and Scroll 5 side is triangular in shape, as shown in Figure 3, the position relationship of preferred two the spread rollers 6 of the present embodiment and Scroll 5, two Scrolls 5 walked around by cloth 8, and the cloth 8 on two Scrolls 5 is in " S " shape, finally be wound on Scroll 5, by above setting, greatly increase cloth 8 and the contact area on spread roller 6 surface, strengthen the spread effect of spread roller 6.
The preferred described spread roller 6 of the present embodiment is arranged in hollow, described helical raised 61 forms helical groove 62 with spread roller 6 surface, described helical groove 62 offers penetrating the first wind inlet 63 to spread roller 6 inside, just knitting cloth 8 surface has more fine hair, by the hollow space of spread roller 6 is connected air intake device, make to form negative pressure in spread roller 6, spread roller 6 is carrying out in spread process to cloth 8, first wind inlet 63 is removed making the fine hair on cloth 8 surface towards the side of cloth 8, makes cloth 8 clean surface; And be positioned on helical groove 62 due to the first wind inlet 63, can't occur directly to contact with cloth 8, prevent from causing scratch to cloth 8 on the one hand, can remove of cloth 8 piece region fine hair when air draught on the other hand.
The present embodiment is preferably provided with aspiration channel 7 between described two supporting bases 1, described aspiration channel 7 is positioned at spread roller 6 hollow space, the cross section of aspiration channel 7 is fan-shaped, the cambered surface of described aspiration channel 7 offers the second wind inlet, due to when cloth 8 contacts with spread roller 6 and not all spread roller 6 is all wrapped up, so by part that the cambered surface side of aspiration channel 7 is wrapped up towards spread roller 6 by cloth 8, when by induced-draught fan 3 air draught, no matter how spread roller 6 rotates, it only has the first wind inlet 63 air draught contacting side with spread roller 6, can avoid the waste of power.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
