Abstract
The utility model discloses a tension controller with balance tension output, which is characterized in that a stationary cylinder is mounted on the base, the base is connected with a rocker through a rockshaft on which a motional cylinder is arranged, and the motional cylinder is tangent to the stationary cylinder. The beneficial effects are that the utility model suppresses the high frequency and low frequency tension fluctuation simultaneously to provide stable tension output after the wires or yarns with tension fluctuation go through the utility model, and thus satisfies the requirement for high accuracy winding and composite material manufacturing.
Description
Technical field:
The utility model relates to the technical field of high-frequency and low frequency tension fluctuation control setup, the device of a kind of specifically energy control and stable motion wire rod vertically or yarn tension, particularly its mechanical connecting structure.
Background technology:
Currently known wire tension device depends on the Be Controlled object mostly, as textile yarn or metal wire rod, and the friction between the tensioner obtains tension increment, is generally undertaken by the normal pressure of the friction pair between change yarn or metal wire rod and the tensioner for the control of this increment.This mode exists obvious defects: the Be Controlled object is had mechanical damage.In addition, enter before the tensioner because of the tension fluctuation due to a variety of causes can't be suppressed, increase to some extent even for wire rod.Other tensioners are to utilize rolling frictional resistance that the elastomeric material pressurized causes to obtain the tension increment of wire rod, are to obtain by change elastic body deformation quantity to the control of tension increment.This mode is better than depending on the mode of wire rod and tensioner friction, not only there is not friction in this mode with controlled object, and owing to some parts in the tensioner roll with wire rod, therefore can utilize the rotor inertia of this rolling member that existing high-frequency tension fluctuation before the wire rod input tensioner is suppressed, but this mode only has inhibit function for high-frequency or paroxysmal tension fluctuation, can't suppress for the low frequency tension fluctuation.The tensioner that also has is to utilize electromagnetic force to reach Tension Control and stable purpose, but parts cost an arm and a leg, and exist during low-speed running device intrinsic because of the tension fluctuation of magnetic pole due to discontinuous.
Summary of the invention:
The purpose of this utility model is to provide a kind of tension control assembly that obtains balance tension output, and it can overcome the shortcoming that existing technology can't suppress high-frequency and low frequency tension fluctuation simultaneously.
To achieve these goals, technical scheme of the present invention is: a kind of tension control assembly that obtains balance tension output, it mainly comprises base, it is characterized in that: described base position is provided with the stationary cylindrical body, base is connected by rocker with rocking bar, the rocking bar place is provided with the motion cylinder, and motion cylinder and stationary cylindrical body are tangent.
The utility model discloses a kind of tension control assembly that obtains balance tension output, its beneficial effect is, can suppress high-frequency and low-frequency tension fluctuation simultaneously, make the wire rod or the yarn that have tension fluctuation obtain very constant tension force output valve, satisfy the requirement that high precision is twined, composite material is made through behind the utility model.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the utility model structural representation.
The specific embodiment:
With reference to the accompanying drawings, the utility model further is described.
The utility model is a kind of tension control assembly that obtains balance tension output, it mainly comprises base 7, it is different from prior art and is: described base 7 places are provided with stationary cylindrical body 10, base 7 is connected by rocker 8 with rocking bar 6, the rocking bar place is provided with motion cylinder 11, motion cylinder 11 is tangent with stationary cylindrical body 10, motion cylinder 11 and stationary cylindrical body 10 are by center shaft 4, ball 5, outside race 3, elastomeric material 2 constitutes, can be provided with 1-60 ball 5 between its center shaft and the outside race, the outside race skin can be provided with elastomeric material 2, rocking bar one side can be provided with seal wire spare 1, and the center shaft 4 of motion cylinder 11 and stationary cylindrical body 10 is parallel to each other.
In the specific implementation, what a pair of surface coated elastomeric material can freely rotate also tangent motion cylinder and stationary cylindrical body around axle separately, both parallel axes are arranged, the center shaft of stationary cylindrical body is fixed, the cylindrical center shaft that moves is fixed in the rocking bar place, rocking bar can rotate around a rocker, the face rocker fix and with two cylinder axis line parallels, control effort acts on rocking bar, the elastic body distortion that forms a moment and exert pressure and make surface both to the stationary cylindrical body by mobile cylinder with respect to rocker.There is not slip at mobile periphery in wire rod or the yarn movement, thereby because of the rolling frictional resistance that areal deformation produces the wire rod in the motion applied a tension increment by cylinder.Wire rod or yarn are folded to after mobile periphery forms an angle of contact, its tension force make a concerted effort by mobile cylinder act on rocking bar form one with the opposite moment of moment direction that forms by control effort, so the moment with respect to rocker is the vectorial sum of control effort and wire rod or yarn tension moment that produces on rocking bar on the rocking bar.Because the cylinder rolling frictional resistance depends on that it is in contact with one another the deformation extent at a place, and deformation extent depends on the normal force of both contact points, so this device has formed a degeneration factor.When the control effort that acts on rocking bar was constant, the input tension force of wire rod or yarn was big more, and the moment on the rocking bar is just more little, the normal force of contact point is more little, the deflection of periphery is just more little, and deflection is more little, and cylinder is just more little to the tension increment of wire rod or yarn.Otherwise tension increment is just big more.As long as the moment that control effort produces is not less than the moment that wire rod or yarn tension cause, this negative feedback just exists all the time.This inverse feedback has realized suppressing the target of any period tension fluctuation with the intrinsic rotor inertia of this system.
