Abstract
The utility model relates to a coaxial-cable knitting tension buffer which can stabilize the tension of a core wire so as to improve the echo test index of the cable; and the coaxial-cable knitting tension buffer has a simple structure and is convenient to use; in the technical scheme, the coaxial-cable knitting tension buffer is characterized in that the buffer is arranged at the bottom of a rack of a cable knitting machine between a lead frame and a core wire disc of the cable knitting machine, and the buffer comprises a guide wheel for buffering the tension of the core wire and two guide rollers for locating the core wire; the axis of the guide wheel is arranged along the horizontal direction and is vertical to the central line of the core wire, and two guide rollers are vertically arranged between the guide wheel and the core wire disc side by side; and a circle of groove of which the diameter is adaptive to the diameter of the core wire is manufactured at the outer edge of the guide wheel along the circumferential direction, and the distance between the two guide rollers is from 0.8cm to 1.5cm.
Description
Technical field
The utility model relates to a kind of cable braiding machine, is specifically related to a kind of coaxial cable knitting tension buffer.
Background technology
The high speed cable braiding machine is a kind of production equipment that outer conductor was made during cable was produced, and is used for the screen (being outer conductor) of braid; After the heart yearn of cable and aluminium foil passed the Go-over mould of braiding machine, Aluminium Foil Package was rolled in the outer wall of heart yearn, and knitting mechanism is woven into the layer of metal silk screen with braided wires outside aluminium foil then, and this layer woven wire and aluminium foil form described screen together.Conventional cable braiding machine as shown in Figure 1, the rack 1 that comprises frame 2 and be arranged on upper rack, it is (clean and tidy for making drawing that knitting mechanism is installed in the rack, omitted among the figure and do not drawn), the bottom of rack is provided with lead frame 6, heart yearn 5 is extracted out from core line disk 3, is pulled into knitting mechanism with aluminium foil after passing through described lead frame.The defective of such cable braiding machine is: owing to be wound with the multilayer heart yearn on the core line disk, the winding direction of adjacent two layers heart yearn is opposite, therefore heart yearn swings back and forth about meeting when core line disk is extracted out, cause the tension force instability of heart yearn, cause heart yearn insulating barrier in the braiding process to deform, influence the aluminium foil evenness (evenness of screen) in when parcel, the echo test index of cable is impacted.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of coaxial cable knitting tension buffer is provided, this buffer should be able to be stablized the tension force of heart yearn, with the echo test index of raising cable, and has characteristics simple in structure, easy to use.
The utility model is by the following technical solutions:
Coaxial cable knitting tension buffer, it is characterized in that: described buffer is arranged on the bottom of cable braiding machine frame, between the lead frame and core line disk of cable braiding machine, comprise a directive wheel that is used to cushion heart yearn tension force, to two deflector rolls of heart yearn location; The axis along continuous straight runs of described directive wheel is arranged and is vertical with the center line of heart yearn; Two deflector rolls vertically are arranged between described directive wheel and the core line disk side by side.
The outer rim of described directive wheel along the circumferential direction is shaped on one and encloses the groove that adapts with core line diameter.
Spacing between described two deflector rolls is 0.8-1.5cm.
Operation principle of the present utility model is: heart yearn is pulled from core line disk, heart yearn can swing back and forth in this process, through behind two deflector rolls and the directive wheel (directive wheel plays cushioning effect), amplitude of fluctuation reduces greatly, again through after the lead frame guiding, amplitude of fluctuation was very little when heart yearn entered vertical bag mould, can not cause the insulating barrier distortion of heart yearn, aluminium foil also can be wrapped on the heart yearn well, improves the screen evenness greatly.
The beneficial effects of the utility model are: directive wheel of the present utility model and two deflector rolls can cushion the tension force of heart yearn, make heart yearn in compilation process, keep comparatively stable tension, improved the evenness of screen greatly, promoted the echo test index of cable, and the utility model is simple in structure, realize that easily cost is also lower.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of normal cable braiding machine.
Fig. 2 is a main TV structure schematic diagram of the present utility model.
Fig. 3 is the right TV structure schematic diagram that cable braiding machine of the present utility model is installed.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As Fig. 2, shown in Figure 3, coaxial cable knitting tension buffer described in the utility model is arranged on the bottom of cable braiding machine frame 2, between the lead frame 6 and core line disk 3 of cable braiding machine, comprises a directive wheel 7, two deflector rolls 8; Described directive wheel is used to cushion the tension force of heart yearn 5, directive wheel is installed on the base plate 2-1 of frame bottom by door font rotating shaft 9 (also can select other rotating shafts for use), the axis along continuous straight runs of directive wheel arranges that its outer rim along the circumferential direction is shaped on one and encloses the groove 7-1 that adapts with core line diameter; Described two deflector rolls are used for heart yearn location (reducing the amplitude that it swings back and forth), and two deflector rolls vertically are arranged between described directive wheel and the heart yearn pay off rack side by side, and the spacing between two deflector rolls and the diameter of heart yearn adapt, and the recommendation spacing is 0.8-1.5cm.
As shown in Figure 3, during work, heart yearn passes between two deflector rolls, is installed in then in the groove of directive wheel bottom, enters knitting mechanism after passing lead frame.Behind cable braiding machine configuration the utility model, how to swing when no matter cable is drawn out of, because the cushioning effect of directive wheel, tension force when heart yearn enters knitting mechanism always is stabilized in definitely in the scope, make aluminium foil entirely to be wrapped on the heart yearn, the screen evenness that knits out is higher, has promoted the echo test index of cable.
Described directive wheel and deflector roll buyable obtain or self-control, and the diameter of directive wheel is determined according to actual needs.Also has heart yearn pay off rack 4 among the figure.
