Description
[technical field]
The utility model relates to wrapped field of mechanical technique, particularly a kind of winding machine constant tension control device.
[background technology]
Winding machine is a kind of equipment applied in the production and processing of cable, and it is wrapped in wire periphery by being rotated by the material strip of sub-thread or multiply difference in functionality, makes it have the performances such as wear-resistant, anti-interference.Material strip is drawn continuously from discharge plate, in order to make material strip closely be wrapped in cable surface, needs the constant tension making material strip.If tension force is too little, can there is fold in wrapped rear material strip, affects cable profile and some function, if tension force is too large, material strip accumulation extension distortion can cause being pulled off, so that produces pause.
Therefore, be necessary to provide a kind of winding machine constant tension control device to solve the problems referred to above.
[utility model content]
Main purpose of the present utility model is to provide a kind of winding machine constant tension control device.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of winding machine constant tension control device, comprise support and rotate the discharge plate be fixed on described support, described discharge plate is coaxially fixed with a friction pulley near described support side, described friction pulley has a belt, pressure adjustable between described belt and described friction pulley saves, and described friction pulley side is provided with the flange for limiting described belt position.
In some embodiments, described support is provided with a substrate, and described belt has a stiff end and a free end, and described belt stiff end is fixed on described substrate side, the activity of described belt free end be fixed on described substrate opposite side.
In some embodiments, described belt free end is fixed on one end of a stud, and described substrate is provided with one for wearing the through hole of described stud, and described stud is arranged with an adjusting nut through the other end of described substrate.
Preferably, a spring is clamped between described adjusting nut and described substrate.
Preferably, described through hole inside is provided with guiding convex ridge, and described stud flank is provided with the gathering sill for accommodating described guiding convex ridge.
With prior art mutually this, the beneficial effect of the utility model winding machine constant tension control device is:
1, controlled the tension force of the material strip of releasing from blowing band by the frictional force between belt and friction pulley, and the size of tension force can lean on the degree of tightness of belt simply to control, easy to use.
2, when flange can prevent belt and friction pulley relative motion, friction pulley deviate from by belt.
3, substrate is as the adjustment basis of belt tension, the tension on belt when adjusting nut precession, and pre-set tension becomes large; When adjusting nut screws out, belt loosens, and pre-set tension diminishes.
4, because the degree of tightness of Tensity size to belt is sensitive, the suitable displacement of adjusting nut and stud can be weakened on the impact of tension force by spring, make adjustment be more prone to control.
5, the guiding convex ridge in through hole and the gathering sill on stud coordinate stud when can prevent adjusting nut from regulating sway so that regulate inconvenience.

[embodiment]
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of winding machine constant tension control device of the present utility model, comprise support 1 and rotate the discharge plate 2 be fixed on support 1, discharge plate 2 is coaxially fixed with a friction pulley 3 near support 1 side, friction pulley 3 has a belt 4, belt 4 has stiff end 41 and a free end 42, and belt 4 controls the pressure between itself and friction pulley 3 by free end 42.Friction pulley 3 side is provided with the flange 31 for limiting belt 4 position.Belt 4 opposite brackets 1 is static, and friction pulley 3 is in rotation, owing to there is stable pressure between belt 4 and friction pulley 3, to produce stable frictional force, friction pulley 3 and discharge plate 2 synchronous axial system, discharge plate 2 is subject to the traction of material strip, balances, make the conveyance tension of material strip constant so the torque of belt 4 frictional force and the torque of material strip tension force produce.
As shown in Figure 1 and Figure 2, support 1 is provided with a substrate 5, belt 4 stiff end 41 is fixed on substrate 5 side, belt 4 free end 42 is fixed on the upper end of a stud 6, on substrate 5, opposite side is provided with a through hole 51, stud 6 other end passes through hole 51 and is arranged with an adjusting nut 7, clamps a spring 8 between adjusting nut 7 and substrate 5.Adjusting nut 7 can by the degree of tightness regulating the relative position of itself and stud 6 to regulate belt 4, because spring 8 is compressible, therefore can weaken the impact that adjusting nut 7 brings with stud 6 relative displacement when adjusting nut 7 regulates, make the degree of tightness degree of regulation of belt 4 more easy to control.
As shown in Figure 3, through hole 51 inside is provided with guiding convex ridge 52, and stud 6 flank is provided with the gathering sill 61 for accommodating guiding convex ridge 52.Thus, be subject to the restriction of guiding convex ridge 52, stud 6 cannot do larger rotation around axle, therefore when adjusting nut 7 regulates, stud 6 can be retreated along through hole 51 direction, changes the tensioning of belt 4 with this, and can not rotate together with adjusting nut 7 and do not reach adjustment object.
During use, first unscrewed by adjusting nut 7, the material strip coiled is loaded onto discharge plate 2 and is started wrapped operation, because material strip is drawn, naturally sends from discharge plate 2, but due to frictional force less, material strip is not yet tightened; Slowly tighten adjusting nut 7, bolt 4 can affect belt 4 to be packed tightly by friction pulley 3 gradually, along with the pressure of belt 4 with friction pulley 3 constantly increases, the frictional force of belt 4 pairs of friction pulleys 3 also increases gradually, the moment that the moment that frictional force is produced and material strip tension force produce balances gradually, material strip will keep suitable tensioned state at the uniform velocity to send, and the tension force of such material strip just can be controlled.
Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
