Abstract

The utility model discloses an aramid fiber pay-off-stand with constant tension, which includes a frame, yarn releasing cylinders at the front part of the frame, and a thread collecting die at the rear part of the frame, and further includes a main shaft rotationally arranged on the frame, a power device for providing power to the main shaft, a rotating side plate fixing the yarn releasing cylinders and fixed on the main shaft, a front thread-crossing ceramic guider fixed on the main shaft and located at the front part of the rotating side plate, and a rear thread-crossing ceramic guider fixed on the main shaft and located at the rear part of the rotating side plate, wherein a through hole allowing aramid fiber to move from the front thread-crossing ceramic guider to the rear thread-crossing ceramic guider is formed on the rotating side plate, and a manual tensioner corresponding to the yarn releasing cylinders is arranged on the main shaft as well as between the rotating side plate and the rear thread-crossing ceramic guider. The aramid fiber pay-off-stand with constant tension has the advantages of constant tension, simple adjustment of the tension and low manufacturing cost.

Description

Permanent tension force aramid fiber pay off rack

Technical field

The utility model relates to a kind of permanent tension force aramid fiber pay off rack, mainly plays the effect that aramid fiber in the cable production process adds, and the running by this equipment is wound into the multiply aramid fiber on the cable core, to reach the technological requirement of product.

Background technology

The existing maximum deficiency of existing aramid fiber pay off rack is a relatively difficulty of Tension Control, and tension force was different fully when traditional pay off rack dishful and tray were put yarn, can not meet technological requirement; If realize Tension Control by electrical control, not only electrical structure complexity, failure rate height, and also control neither be very accurate.

The utility model content

Technical problem to be solved in the utility model provides and a kind ofly can keep constant tension, the simple aramid fiber pay off rack of Tension Control.

For solving above technical scheme, the utility model is taked following technical scheme: a kind of permanent tension force aramid fiber pay off rack, comprise framework, what be arranged on frame front puts the yarn tube, be arranged on the line concentration mould of frame rear portion, also comprise: rotate the main shaft that is arranged on the framework, be used for providing the power set of power to this main shaft, be fixed on a plurality of rotation side plates of putting the yarn tube of having fixed on this main shaft, be fixed on this main shaft and be positioned at and rotate leading with the above-mentioned corresponding preceding line porcelain of crossing of yarn tube of putting respectively of side plate front portion, be fixed on this main shaft and be positioned at corresponding with the above-mentioned yarn tube respectively back line porcelain of crossing that rotates the side plate rear portion and lead, also offer on the described rotation side plate and make aramid fiber can be in the past cross the line porcelain to lead and move to the back and cross the through hole that the line porcelain is led, on the described main shaft also the rotation side plate with the back the line porcelain also be fixed with the manual tensioner corresponding between leading with putting the yarn tube.

Described power set comprise the reducing motor that is fixed on the framework, be used to connect the synchronous band mechanism of described reducing motor and described main shaft.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: (1), this pay off rack can be used for many aramid yarns are wrapped on the product with constant tension force, the external diameter of laying tension and yarn tube and the rotary speed of main shaft are irrelevant, and traditional pay off rack dishful and tray when putting yarn tension force different fully; (2), can directly control the laying tension of aramid fiber (traditional unwrapping wire employing active or passive type by regulating manual tensioner, laying tension is all realized by electrical control, failure rate is higher), both conveniently controlled, winding process is simple, but also significantly reduced the appearance of electric fault; (3), the integral production cost descends after this architecture advances, only is equivalent to half of original identical device cost.

Description of drawings

Fig. 1 is that master of the present utility model looks partial sectional view;

Wherein: 1, reducing motor, 2, be with mechanism synchronously, 3, main shaft, 4, the preceding line porcelain of crossing leads, 5, the rotation side plate, 6, put the yarn tube, 7, manual tensioner, 8, the back crosses the line porcelain and lead, 9, the line concentration mould, 10, die frame, 11, framework, 100, cable core, 200, aramid fiber.

Embodiment

Permanent tension force aramid fiber pay off rack as shown in Figure 1 comprises framework 11, is arranged on putting yarn tube 6, being arranged on the line concentration mould 9 at framework 11 rear portions of framework 11 front portions, and this front portion is relative production technology with the rear portion, is the rear portion as the figure left side for anterior, right side.

This pay off rack also comprises and rotates the main shaft 3 be arranged on the framework 11, the power set that are used for providing power to this main shaft 3, described power set comprise the reducing motor 1 that is fixed on the framework 11, be used to connect the synchronous band mechanism 2 of described reducing motor 1 and described main shaft 3, and this reducing motor 1 can be the structure of driven by motor decelerator.

Be fixed with rotation side plate 5 on the described main shaft 3, fix 10 on the described rotation side plate 5 and put the yarn tube, being positioned at rotation side plate 5 front portions on the described main shaft 3 is fixed with respectively with the above-mentioned corresponding preceding line porcelain of crossing of yarn tube 6 of putting and leads 4, being positioned at rotation side plate 5 rear portions on the described main shaft 3 is fixed with respectively back the cross line porcelain corresponding with above-mentioned yarn tube 6 and leads 8, also offer on the described rotation side plate 5 and make aramid fiber can be in the past cross the line porcelain to lead 4 and move to the back and cross the line porcelain and lead 8 through hole, on the described main shaft 3 also rotation side plate 5 with the back the line porcelain lead and also be fixed with the manual tensioner 7 corresponding between 8 with putting yarn tube 6.

The operation principle of above-mentioned pay off rack is: cross the line porcelain before putting aramid fiber 200 on the yarn tube 6 and at first passing and lead 4, the through hole through offering on the side plate 5 passes through manual tensioner 7 more again, passes the back again and crosses the line porcelain and lead 8, concentrates at last on the line concentration mould 9.Manually the front and back station of tensioner 7 is that porcelain is led, and therefore just can guarantee aramid fiber 200 constant tensions, not put yarn tube 6 diameters and main shaft 3 rotating speeds influence by the setting of adversary's dynamic tension device 7.

Reducing motor 1 drives band mechanism 2 synchronously, drives main shaft 3 rotations, and other tracting mechanism drives cable core 100 towards right motion, then aramid fiber 200 relatively cable core spin motion, be wrapped on the cable core 100 in a spiral manner.
