Description
Technical field
The utility model relates to a kind of steel cord and produces device used, relates in particular to a kind of payoff tensioner, belongs to mechanical device technical field.
Background technology
Steel cord is material requested during rubber tyre is manufactured, it is formed by many all-steel cords twisting on strander, at present in cord twisting process, because the full wheel unwrapping wire arm of force is different from the wheel end unwrapping wire arm of force, cause and initially completely take turns that laying tension is less, return pulley monofilament laying tension is larger, thereby affect the inhomogeneities of cord twisting.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of payoff tensioner, makes monofilament laying tension in twisting process remain uniformity, has avoided the inhomogeneities of cord twisting.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of payoff tensioner, comprise the unwrapping wire arm of force that gland is connected with gland by extension spring with lower end, the upper end of the described unwrapping wire arm of force is provided with unwrapping wire base frictional disk around the fricting strip contacting, be provided with a friction arm of force in described unwrapping wire arm of force lower end, the top of the described friction arm of force is connected with a friction plate by fixing expansion link, described friction plate contacts with unwrapping wire base frictional disk, and described friction plate and fricting strip are oppositely arranged.
Further, described friction plate is T shape friction plate.
Further, the described expansion link of fixing is connected with the friction arm of force by bearing pin, can fix expansion link and regulate it also fixing with the connection angle of the friction arm of force by bearing pin, thereby regulate the horizontal level of fixing T shape friction plate.
Further, the described friction arm of force is weldingly fixed on unwrapping wire arm of force lower end.
Further, the described friction arm of force is 60 ° with the crossing angle of the unwrapping wire arm of force.
Usefulness of the present utility model is: by the payoff tensioner after improving, ensured laying tension size evenly, made monofilament tension force in twisting process remain uniformity, avoided the inhomogeneities of cord twisting; And the utility model is little to the repacking of existing lathe, repacking cost is less, can put into production fast, improves the laying tension fluctuation of cord.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Fig. 1 is the structural representation of the present embodiment actinobacillus device; Fig. 2 is the utility model structural representation;
As illustrated in fig. 1 and 2: the present embodiment is a kind of payoff tensioner, comprise the unwrapping wire arm of force 4 that gland 1 is connected with gland 1 by extension spring 2 with lower end, the upper end of the unwrapping wire arm of force 4 is provided with unwrapping wire base 6 frictional disks around the fricting strip 5 contacting, be provided with a friction arm of force 3 in the unwrapping wire arm of force 4 lower ends, the top of the friction arm of force 3 is connected with a T shape friction plate 9 by fixing expansion link 7, T shape friction plate 9 contacts with unwrapping wire base 6 frictional disks, and described T shape friction plate 9 is oppositely arranged with fricting strip 5; Wherein, can fix expansion link 7 and be connected with the friction arm of force 3 by bearing pin 8, can fix expansion link 7 and regulate it also fixing with the connection angle of the friction arm of force 3 by bearing pin 8, thereby regulate the horizontal level of fixing T shape friction plate 9; In the present embodiment, the friction arm of force 3 is weldingly fixed on the unwrapping wire arm of force 4 lower ends; And the friction arm of force 3 is 60 ° with the crossing angle of the unwrapping wire arm of force 4.
On the upper thread unwrapping wire base of DTU lathe of producing 1622 heart yearns, the friction arm of force 3 is weldingly fixed on to the unwrapping wire arm of force 4 lower ends, the friction arm of force 3 angle crossing with the unwrapping wire arm of force 4 is 60 °; The top of the friction arm of force 3 is connected with a T shape friction plate 9 by fixing expansion link 7, regulate the connection angle that can fix expansion link 7 and the friction arm of force 3 by bearing pin 8, further regulate contact angle and the position of T shape friction plate 9 and unwrapping wire base 6 frictional disks, T shape friction plate 9 is under static state just contacted with the frictional disk of unwrapping wire base 6, after adjusting, can fix expansion link 7 and be fixed on the friction arm of force 3 tops by bearing pin 8; In the time of return pulley monofilament unwrapping wire, because being pulled to return pulley, monofilament make tension force larger, and now T shape friction plate 9 does not contact with the frictional disk of unwrapping wire base 6; Regulate fricting strip 5, make laying tension FThe endMeet technological requirement, on this basis, in the time of full wheel monofilament unwrapping wire, completely take turns drawing because of monofilament and make tension force less, now regulate T shape friction plate 9 to contact with the frictional disk of unwrapping wire base 6, ensure now tension force FJustWith FThe endIdentical, the tension force while reaching full wheel unwrapping wire with return pulley unwrapping wire is identical.
It is 1.6N that the present embodiment is tested return pulley monofilament laying tension in advance; In the time that monofilament unwrapping wire is completely taken turns in replacing, adjustment can be fixed expansion link 7 fixing and locking, and T shape friction plate 9 is contacted with the frictional disk of unwrapping wire base 6, raise and initially completely take turns laying tension to 1.6N, thereby the tension force while having reached full wheel unwrapping wire with return pulley unwrapping wire is identical.
The utility model, by the payoff tensioner after improving, has ensured laying tension size evenly, makes monofilament tension force in twisting process remain uniformity, has avoided the inhomogeneities of cord twisting; And the utility model is little to the repacking of existing lathe, repacking cost is less, can put into production fast, improves the laying tension fluctuation of cord.
More than show and described general principle of the present utility model, principal character and advantage; the technical staff of the industry should understand; above-described embodiment does not limit the utility model in any form; all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
