Abstract
The utility model discloses a small capacity capacitor capacity adjusting device which comprises an upper roller shaft and a lower roller shaft. A first tapered roller is arranged on the upper roller shaft through a sliding bearing. A reset spring is arranged between the first tapered roller and a retaining wall. An adjusting nut is arranged on the front end of the upper roller shaft. The rear end of the adjusting nut tightly abuts against an inner bearing on the blunt end of the tapered roller. A first retaining ring is arranged on the tip of the first tapered roller. A second tapered roller is arranged on the lower roller shaft through a fixed bearing. The tip of the second tapered roller is back to a winding machine retaining wall. A second retaining ring is arranged on the tip. An axial space is between the first retaining ring and the second retaining ring, and the space is adjusted by the adjusting nut. According to the utility model, when a winding machine carries out winding, in advance of aluminum foil transmission, the lamination width of an aluminum foil is precisely adjusted; the capacity of a film capacitor is conveniently and precisely adjusted; and the device has the advantage of high practicability, and is worthy of promotion.
Description
Technical field
The utility model relates to the manufacturing technology of film capacitor, relates in particular to a kind of low value capacitor capacity regulating device.
Background technology
The making of current thin film capacitor is all to adopt up-coiler to carry out, and refers to Fig. 1, and film capacitor mainly contains two aluminium foils 6 and two insulating barriers 7 form, and wherein, the capacity of capacitor is by two W
1the aluminium foil of width and W
2superimposed part effective width W between the foil electrode of width
0determine W
0the capacity of larger electric capacity is larger, otherwise just less, under current technology, and the W of aluminium foil
1and W
2the minimum widith of cutting be 3 millimeters, when producing the film capacitor of 101 specifications, (capacity is that 0.0001 μ is f) or more when low capacity specification product, even if its capacity of aluminium foil of the superimposed 1 millimeter of width of the aluminium foil of the width of 3 millimeters is also far beyond the capability value requiring, and because aluminium foil inevitably exists and swings in curly course, make superimposed width W
0also exist and change, therefore at present in industry the film capacitor of 101 specifications and more low capacity specification product production difficulty even cannot produce.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of low value capacitor capacity regulating device.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: a kind of low value capacitor capacity regulating device, comprises the upper roll shaft and the lower roller shaft that are fixed on up-coiler barricade one side and be arranged in parallel; On described upper roll shaft, by sliding bearing, the first conical drum is installed, the tip of described the first conical drum is towards up-coiler barricade, and tip is provided with the first baffle ring, between described the first baffle ring and up-coiler barricade, be provided with the back-moving spring that is placed on roll shaft, the front end of the described upper roll shaft adjusting nut that is threaded, the rear end of described adjusting nut holds out against in the inner bearing of the blunt end of described the first conical drum; On described lower roller shaft, by rigid bearing, the second conical drum is installed, the tip of described the second conical drum is back in up-coiler barricade, and tip is provided with the second baffle ring, axially upper tool between described the first baffle ring and the second baffle ring is at regular intervals, and this spacing size regulates by adjusting nut.
Compared with prior art, the utility model can be used on up-coiler, mainly at up-coiler during in curling operation, in advance in the time that aluminium foil transmits, just regulate the superimposed width of aluminium foil, thereby regulate the capacitance of film capacitor, make existing up-coiler can produce the capacitor that capacity is less, and capacity qualification rate has been high.Two conical drums that wherein adopt are crisscross arranged, can be by spacing two aluminium foils on the inclined-plane of conical drum, then regulate the upper conical cylinder of adjusting upper roll axle by the nut arranging, thereby regulate up-coiler in the time of curling operation, superimposed width between two aluminium foils, and practical, easy for installation, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is the structural representation of the film capacitor of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 2, the low value capacitor capacity regulating device the utility model proposes, comprises and is fixed on up-coiler barricade 1 one sides and the upper roll shaft 2 be arrangeding in parallel and lower roller shaft 3; On upper roll shaft 2, by sliding bearing 21, the first conical drum 4 is installed, sliding bearing 21 is two, at the two ends of the first conical drum 4, such the first conical drum 4 just can move left and right on upper roll shaft 2, the tip of the first conical drum 4 is towards up-coiler barricade 1, and tip is provided with the first baffle ring 41, between the first baffle ring 41 and up-coiler barricade 1, be provided with the back-moving spring 42 that is placed on roll shaft 2, the front end of upper roll shaft 2 adjusting nut 43 that is threaded, the rear end of adjusting nut 43 holds out against the inner bearing 44 in the blunt end of the first conical drum 4; On lower roller shaft 3, by rigid bearing 31, the second conical drum 5 is installed, rigid bearing 31 is two, be separately positioned on the two ends of the second conical drum 5, the tip of the second conical drum 5 is back in up-coiler barricade 1, and tip is provided with the second baffle ring 51, axially upper tool between the first baffle ring 41 and the second baffle ring 51 is at regular intervals, and this spacing size regulates by adjusting nut 43.
The utility model mainly arranges on up-coiler, mainly to be adjusted in before curling work, in advance by spacing on the inclined plane of first, second conical drum two aluminium foils 6, because be inclined plane, so in the time that aluminium foil transmits, aluminium foil 6 is along with conical drum tilts, and first, second baffle ring arranging just can be by spacing aluminium foil 6 on two conical drums, and aluminium foil 6 one side and baffle ring maintain an equal level, and now between the aluminium foil of the first conical drum and the aluminium foil of the second conical drum, have in the axial direction a spacing W
0, in fact W
0the superimposed width W of two aluminium foils 6 while being exactly up-coiler rolling
0, wherein the first conical drum can also be by sliding bearing 21, uses adjusting nut 43 to move left and right the first conical drum, so just spacing W according to actual needs
0, and the back-moving spring 42 arranging, can coordinate the adjusting work of adjusting nut 43, left and right promotes the first conical drum.
Above-described embodiment has only been expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the utility model patent and protection range should be as the criterion with appended claims.
