Description
Technical field
The utility model is related to winding tape apparatus, specially a kind of helix device.
Background technology
It is frequently encountered a kind of situation in the factory, exactly many belts of same size are stacked together, are played
The effect of cushion.For example, in the production of current dry-type transformer, it will usually multilayer DMD insulating papers be wound, Ran Hou
The copper foil of multilayer-wound on the DMD insulating papers outer surface wound.For better wind-cooling heat dissipating between every layer of copper foil, it will usually
I-shaped stay is laterally clipped between copper foil and realizes the gap formed between copper foil and copper foil convenient for air flowing, while can be in copper
The two sides of foil overlay two lateral edges of copper foil using the DMD insulating papers of multilayer, copper foil are propped up certain gap, at this time
Due to that in order to ensure certain heat dissipation gap between copper foil, can use stacked together not less than 5 to 6 layers of DMD insulating paper layers.But
It is that general DMD insulating papers are due to being band-like structure, and with regard to needing, a people is special to smooth out with the fingers five or six layers of DMD insulating papers
The lateral edges of copper foil are pressed in along after.So be typically that two people cooperate together in practical winding copper foil work, people's volume
Ensure that every layer of copper foil can be aligned around copper foil, another person is smoothed out with the fingers along the compacting of DMD insulating papers.Such working method efficiency is not
Height, and can also delay manufacturing schedule during manually smoothing out with the fingers along DMD insulating papers.
In this regard, the utility model proposes a kind of new solutions.It realizes liberation manpower work, improves production efficiency.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Shown in Fig. 1 to Fig. 5, a kind of helix device, including：
Rotating cylinder 1 is superimposed, is freely rotated with respect to mandrel 3, this mandrel 3 can be secured in the rack of up- coiler, be
The convenience used can also allow mandrel 3 to be directed at the lateral edges of copper foil, the structure of superposition rotating cylinder 1 be cylindrical structure and in
The heart is circular hollow, is superimposed rotating cylinder 1 in this way and is just very easily rotated relative to mandrel 3；1 outer surface of the superposition rotating cylinder is equipped with
The winding slot 2 of helical form U-shaped structure, the size of this winding slot 2 and the equivalent width of DMD insulating papers, can be in order to single laminate roll
Band 6 is just sticked into winding slot 2；And several split rotating cylinders 4, the aperture position of winding slot 2 is faced, and be arranged on folded
Add around 1 outer circumference surface of rotating cylinder；Single laminate roll band 6 on each split rotating cylinder 4 spiral in the same direction from winding slot 2 is superimposed
It is laid out after forming superposition winding 7 from same position；The center of the split rotating cylinder 4 is equipped with the split shaft 5 rotated freely.When
When single laminate roll band 6 is applied the rotation of rotating cylinder 1 superposition together, each split rotating cylinder 4 can be allowed to turn with superposition rotating cylinder 1
Dynamic and synchronous rotation, it is necessary, of course, to ensure that the direction being wound on superposition rotating cylinder 1 of each single laminate roll band 6 is all clockwise
Or counterclockwise, it is only necessary to ensure when the rotation of rotating cylinder 1 is superimposed, corresponding each split rotating cylinder 4 is also due to single laminate roll
It pulls and rotates with 6, and no matter the single laminate roll band 6 of how many layers of superposition, it can be neat folded together in winding slot 2
Add.Finally be superimposed neat single laminate roll band 6 can be wound copper foil worker pull after, be wound up into two sides of copper foil therewith
Edge.
In actual use, due to winding copper foil machine pulling force it is very big, not only copper foil can be stretched tight very tight, also can from
It is superimposed the superposition winding 7 on rotating cylinder 1 out and also stretches tight very tight.But in each single laminate roll band 6 all in the very big situation of pulling force
Under, due to ensureing that each single laminate roll band 6 will be completely fastened in winding slot 2 again, if somewhat deviation can lead to list
The edge of layer winding 6 is pressed onto the side edge of winding slot 2, in this case, along with pulling force causes greatly each single laminate roll band 6 taut very much
Must be very tight, therefore the edge of single laminate roll band 6 can be caused the situation of bending occur.In order to preferably prevent DMD insulating papers in winding
What is be bent in slot 2 happens, can further, and the cross sectional shape of the winding slot 2 is isosceles trapezoid.Adding isosceles
Behind trapezoidal cross section, even if there is DMD insulation paper edge not to be aligned with winding slot 2, the isosceles being inclined by that also can be quickly are terraced
Shape inclined-plane slides the bottom of big winding slot 2, can ensure the stabilization of work in this way.And can also using the bevel edge of isosceles triangle
The lateral edges of single laminate roll band 6 each in superposition winding 7 are softened, the superposition winding 7 after the softening of side can allow superposition winding 7 to have
There is the extruding force preferably born between copper foil.
, can also further in addition to above-mentioned section is isosceles trapezoid, the two sides of the winding slot 2 are the arcs of indent
Shape.Have the characteristics that landing is rapid compared to isosceles trapezoid inclined-plane using the structure of arc, and at the same time winding slot 2 can also be reached
Bottom have softening edge effect.
In order to which better fixed overlay rotating cylinder 1 and split rotating cylinder 4 realize better work, further, all splits turn
The both ends of axis 5 be fixed to two with to be superimposed rotating cylinder 1 concentric and generally on helical form fixed frame 8.Pass through spiral helicine fixation
Frame 8 can ensure that the split rotating cylinder 4 on each fixed frame 8 can be just snapped in winding slot 2, pass through spiral helicine fixed frame
8, it is ensured that each split rotating cylinder 4 will not conflict collision, and ensure more preferable stabilization allows each single laminate roll band 6 to be superimposed structure
Into superposition winding 7.
Operation principle：When in use, the split turn that single laminate roll band 6 is housed can be covered in each split shaft 5
Cylinder 4, is then pressed in single laminate roll band 6 in winding slot 2 successively according to the thread rotary orientation of winding slot 2, and then final superposition is rolled up
It is directly wound up on the lateral edges of copper foil with 7, with the rotation of fixed copper foil mold, tenses superposition winding also with rotation in this way
7, and then complete the purpose of superposition multilayer single laminate roll band 6.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case of the principle and spirit for not departing from the utility model, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
