Description
Technical field:
The utility model relates to cable production fields, are especially a kind of back-twist device of stranding machine.
Background technique:
In cable production, when core wire especially particle size copper wire combines twisted wire through stranding machine, since single copper wire is from winding
It is unwound on drum, causes torsion excessive, be easy to cause plying not close after plying, shadow is caused to the cable quality of finished product
It rings.
Utility model content:
Technical problem to be solved by the utility model is to provide the strands that one kind can reduce torsion of the copper wire before twisted
The back-twist device of line machine.
The technical solution of the utility model is to provide a kind of back-twist device of stranding machine, including is fixed on stranding machine
Rectangular adjustable plate on main shaft, adjustable plate are equipped at intervals with 3 fixation holes along its length, are equipped with bolt in fixation hole,
The screw rod of bolt is just facing the back side from adjustable plate and is being arranged on fixation hole, the screw rod of adjustable plate front side rotatably
Roller is combined with nut on the screw rod of adjustable plate reverse side, adjustment hole is additionally provided between adjacent fixation holes, adjustment hole is strip
Hole, and be arranged along the width direction of adjustable plate, it is equipped with adjusting bolt in adjustment hole, adjusts bolt and is located at adjustable plate front side
It is arranged with rotatable roller, adjusting bolt is located at adjustable plate reverse side and is fastened with locking nut.
After using the above structure compared with prior art, the utility model has the advantage that by stranding machine main shaft
On the setting back-twist device, so that copper wire is first passed through the back-twist device before twisted to reduce torsion, copper wire made to become straight, this
Sample can be tighter with obvolvent when twisted, improves cable quality.
Preferably, 3 fixation holes are close to the top setting of adjustable plate, and the distance apart from adjustable plate top is consistent.
Preferably, adjustable plate is fixed on the main shaft of stranding machine by anchor ear.
Further, the circumference of roller is equipped with annular groove.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the rearview of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1 and Figure 2, a kind of back-twist device of stranding machine, including the rectangular tune being fixed on stranding machine main shaft
Plate 1 is saved, adjustable plate 1 is equipped at intervals with 3 fixation holes along its length, is equipped with bolt in fixation hole, and the screw rod of bolt is from adjusting
Plate is just facing the back side and is being arranged with rotatable roller 2 on fixation hole, the screw rod of the positive side of adjustable plate 1, and adjustable plate 1 is carried on the back
It is combined with nut 3 on the screw rod of face side, adjustment hole 4 is additionally provided between adjacent fixation holes, adjustment hole 4 is strip hole, and along tune
The width direction setting of plate is saved, is equipped in adjustment hole 4 and adjusts bolt 5, adjusting bolt 5 is located at adjustable plate front side and is arranged with
Rotatable roller 2, adjusting bolt 5 are located at adjustable plate reverse side and are fastened with locking nut 6.By the tune in adjustment hole when use
Section bolt is adjusted to suitable position, and copper wire is allowed successively to pass through each idler wheel, realizes the adjustment to copper wire torsion.Wherein, 3 fixations
Hole is close to the top setting of adjustable plate, and the distance apart from adjustable plate top is consistent, and adjustable plate is fixed on twisted wire by anchor ear
On the main shaft of machine, the circumference of roller is equipped with annular groove, and annular groove can accommodate copper wire, in addition, due to the tune in adjustment hole
Section bolt needs to be fastened on adjustable plate, adjusts and is arranged with casing on bolt, casing one end offsets with bolt head, and casing is another
End is resisted against adjustable plate front, and then roller is set on casing, and can facing sleeve rotation.Certainly, for screw bolt and nut
Cooperation, tie spacer ought to be customary means.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
