The permanent tension force lapping device of twining package tape
Technical field
The invention belongs to the electric wire technical field of processing equipment, be specifically related to the permanent tension force lapping device of a kind of twining package tape
Background technology
As is known in the industry, at the electric wire production industry, often relate to the operation of the twining package tape that outside conductor and/or cable core, is wrapped, twining package tape such as mica tape, mylar tape, aluminium foil strip, cotton paper band, etc., play shielding, insulation or fire retardation to cable according to the heterogeneity of twining package tape and technological requirement.
Aforesaid twining package tape is processed into disc configuration usually, and the total length of a coiling band is hundreds of rice at least, and thousand and tens of thousands meter at most, the wrapped efficient and the appropriateness that improve winding machine so that the dish frequency is changed in minimizing alleviate workman's manipulation strength.And then as is known in the industry, technological factor aspect in the wrapped process outside conductor or cable core with twining package tape, mainly considering two, the one, packet stack rate, the 2nd, the tension force of twining package tape, control to packet stack rate in the prior art is masterly, namely there is not technology barrier at all, but the control to twining package tape tension force suffers from industry for a long time all the time, because, with regard to whole coiling band, along with the quantity of the twining package tape on the wrapped tep reel reduces gradually, the diameter of wrapped tep reel is corresponding to diminish, and the tension force of twining package tape changes simultaneously.Theoretically, when twining package tape is in the dishful state, the rotating speed of wrapped tep reel is corresponding slowly, otherwise along with the quantity of twining package tape on wrapped tep reel is that sum reduces gradually, the then corresponding raising of the rotating speed of wrapped tep reel, move back band (withdrawing from from wrapped tep reel) linear velocity with the compensation twining package tape, the linear velocity that is to say twining package tape remains at same degree and is not subjected to the variable effect of the total length on the wrapped tep reel is the perfect requirement of around-packing technology, but often is difficult to satisfy this requirement in the operation process of reality.
Figure 3 shows that the schematic diagram of the twining package tape tenslator in the prior art.Comprise a frame 1, on this frame 1, be provided with rotationally a frictional disk 11, and on frame 1, also be equipped with one for the friction force adjustment mechanism 12 that the frictional force of frictional disk 11 is adjusted, this friction force adjustment mechanism 12 comprises adjusting bolt 121, lever 122, extension spring 123 and friction are with 124, the middle part pivot of the length direction of lever 122 is arranged on the lever branching holder 1221, lever branching holder 1221 is fixed on the frame 1, one end of lever 122 is provided with a tape guide roller 1222 rotationally, adjusting bolt 121 is arranged on the frame 1, and be arranged with a spring 1211 in this adjusting bolt 121, one end of extension spring 123 is fixed on the frame 1, and the other end of extension spring 123 is connected with the other end of lever 122, friction is connected with adjusting bolt 121 with an end of 124, the middle part envelope is on frictional disk 11, and friction is fixed on the frame 1 with 124 the other end.During use, the wrapped tep reel 2 that will have twining package tape 21 is nested with on the frictional disk axle of frictional disk 11, be that wrapped tep reel 2 is coaxial with frictional disk 11, by way of tape guide roller 1222 with pivot and introduce illustrated coiler device 10 after being arranged on transition tape guide roller on the frame 1, twining package tape 21 is wrapped outside conductor 20 making under the work of coiler device 10 successively for the twining package tape 21 of drawing from wrapped tep reel 2.Minimizing along with the quantity of twining package tape 21 on wrapped tep reel 2, by the workman adjusting bolt 121 is regulated, make friction with 124 frictional force that reduce frictional disk 11, the faster rotational speed of frictional disk 11, because wrapped tep reel 2 is coaxial with frictional disk 11, therefore the also corresponding raising of rotating speed of wrapped tep reel 2, the Speed improving that twining package tape 21 withdraws from from wrapped tep reel 2, otherwise with example.Although this tenslator can satisfy the tension force control requirement to twining package tape, but because the minimizing process of the twining package tape on the wrapped tep reel is continuation, it is variation at all times, again because the workman is period (or claiming interim) to the adjusting of adjusting bolt, therefore, can not guarantee that twining package tape continues constant tension force, thereby be difficult to the wrapped effect that the guarantee phase gets.In addition, because tension adjustment relies on workman's manual operations to realize, therefore not only be subject to the impact of workman's experience and sense of duty difference, but also be subject to the impact of workman's mood, thereby make tension force control lose science and labor strength large (for example being in the biotonus of height).
In view of above-mentioned prior art, be necessary to be improved, the applicant has done useful design for this reason, has finally formed technical scheme described below, and test in the applicant plant area under the strict secrecy provision having taked, it is practicable that the result proves
