Description

Technical Field

[0001] The invention belongs to the technical field of capacitor preparation, and in particular relates to a winding machine flattening device and a use method thereof. Background Art

[0002] On the film capacitor winding machine, the film roll will be wrinkled to varying degrees due to the front-end process or storage process, and it may also be wrinkled during the winding process. Film wrinkling greatly affects the quality of the core winding in capacitor preparation, causing problems such as reduced product withstand voltage and capacity deviation. Therefore, a device that can flatten the film is needed.

[0003] Patent document with application number CN201210502550.4 discloses a film flattening roller, including a roller, ribs and a rotating shaft, wherein the surface of the roller is provided with ribs, and the rotating shafts are provided at both ends of the roller. In order to ensure smooth and smooth transmission of the film product, the ribs are composed of left spiral ribs and right spiral ribs, and the left spiral ribs and the right spiral ribs are distributed in a spiral shape on the surface of the roller. The ribs are welded to the surface of the roller by one or more round steel wires.

[0004] However, the structure of the above patent has limited flattening effect on film products, and its flattening effect is fixed. Because the flattening effect is determined by the angle of the convex ribs on its surface, this structure cannot adapt to the flattening of films with different degrees of wrinkling, and its usage scenarios are relatively limited.

[0005] At the same time, the structure of this patent requires that the center line of the film be as close as possible to the center line of the roller axis to obtain a better flattening effect. If the film deviates from the center line of the roller axis, or the film does not cover the center line of the roller axis, the structure loses the flattening effect.

[0006] The patent document with application number CN202210902819.1 discloses a diaphragm flattening device, which relates to the field of diaphragm winding technology, and in particular to a diaphragm flattening device, including: a flattening roller, the outer peripheral surface of the flattening roller is provided with at least two strip grooves, the two strip grooves are symmetrical and distributed in an eight-shaped shape along the radial section passing through the axial midpoint of the flattening roller, and the two ends of the two strip grooves form a large opening end and a small opening end respectively, and the flattening roller rotates circumferentially from the small opening end to the large opening end. The diaphragm flattening device of the present invention is provided with an eight-shaped groove on the flattening roller. When the diaphragm contacts the eight-shaped groove, the inclined strip groove will exert a lateral expansion force on the film, pushing the diaphragm to both sides, and effectively achieving the purpose of flattening the diaphragm. However, the device also has the above-mentioned defects, and requires the center line of the film to be as close as possible to the center line of the roller axis. Summary of the invention

[0017] Preferably, the bending arc of the connecting rod is 5-10 degrees, and the central angle formed by the connecting rod is 20-40 degrees.

[0018] A method for using a winding machine flattening device comprises the following steps:

[0019] S1: The fixing frame is installed at the film pulling-out position of the winding machine so that the film is placed above the rotating member. Since the connecting rod is bent, when the connecting rod is rotated until it does not contact the film, it is the minimum adjustable gear of the rotating ring. At this time, the flattening device has no flattening effect on the film.

[0020] S2: Rotate the rotating ring until the bending part of the connecting rod contacts the film. Continue to rotate the rotating ring to make the bending part of the connecting rod upward.

At this time, the flattening area of ​​the film by the flattening device is the largest.

[0021] The beneficial effects of the present invention are:

[0022] The present invention drives the connecting rod by adjusting the rotation of the mounting rod, so that the connecting rod and the film present different angles, which can adapt to the flattening of films with different wrinkle degrees; the maximum flattening effect can be achieved by making a curved rod with a higher curvature, which is better than the traditional flattening method. The connecting rod protrudes outward at any position, and the film can obtain a good flattening effect when passing through the device at any position; by rotating the rotating ring and observing the pointer and the scale line at the same time, the adjustable function of the flattening effect can be achieved: when the plane where the connecting rod is located is perpendicular to the direction of the film passing, the maximum flattening effect is achieved, and rotating to both sides will obtain a smaller flattening effect, and it has strong versatility.

[0030] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0031] Example:

[0032] like Figures 1 to 6As shown, a winding machine flattening device and a method of using the same include a supporting assembly and a flattening assembly, wherein the flattening assembly includes a mounting base plate 1, a mounting rod 3, a rotating member 4 and a connecting rod 5, wherein one end of the mounting rod 3 is connected to the supporting assembly after being rotatably connected to the mounting base plate 1, and the other end of the mounting rod 3 is connected to one end of the connecting rod 5, the connecting rod 5 is connected through the rotating member 4, and the other end of the connecting rod 5 is connected to the supporting assembly.

[0033] The mounting base plate 1 is provided with scale lines 2, the rotating member 4 is a high-speed bearing, the connecting rod 5 is bent, and a plurality of rotating members 4 are provided on the connecting rod 5. The arc formed by the connecting line of the edges of all rotating members 4 has the same arc as the connecting rod 5.

[0034] The support assembly includes a support frame 6 and a fixed frame 7. The bottom of the support frame 6 is connected to the fixed frame 7. The support frame 6 is set at two places, the top of the support frame 6 at one place is connected to the mounting rod 3, and the top of the support frame 6 at the other place is rotatably connected to the connecting rod 5.

[0035] The mounting rod 3 is provided with a rotating ring 31, and an anti-slip groove can be provided on the rotating ring 31 for easy rotation. The mounting rod 3 passes through the rotating ring 31 and is connected. A pointer 32 is provided on the rotating ring 31. The mounting rod 3 is rotated by rotating the rotating ring 31, and different scale lines 31 are aligned according to the pointer 32, so as to adjust the angle of the flattening device to the film 9.

[0036] The support frame 6 is provided with a rotating disk 8, the support frame 6 is rotatably connected with the rotating disk 8, and the support frame 6 is connected with the connecting rod 5 through the rotating disk 8. The rotating disk 8 is coaxially arranged with the mounting rod 3, and the rotating disk 8 is non-coaxially arranged with the connecting rod 5, and the diameter of the rotating disk 8 is larger than the diameter of the connecting rod 5. This arrangement can prevent the bent connecting rod 5 from being interfered with during rotation.

[0037] The support frame 6 and the fixing frame 7 are vertically connected, and the support frame 6 and the fixing frame 7 are connected by bolts or welding. The support frame 6 can be hollow to reduce weight.

[0038] The fixing frame 7 is provided with a hole 71 , and the fixing frame 7 can be connected to the mounting platform by passing a bolt through the hole 71 , thereby fixing the flattening device on the mounting platform.

[0039] When the film 9 passes through the device, the film is bent from a straight line to a curve by the rotating member 4 and the connecting rod 5, thereby increasing the width of the film 9 and causing the film 9 to be subjected to forces on both sides to achieve the effect of flattening and wrinkling.

[0040] The bending arc of the connecting rod 5 is 5-10 degrees, preferably 7 degrees, and the central angle formed by the connecting rod 5 is 20-40 degrees, preferably 27 degrees.

[0041] A method for using a winding machine flattening device comprises the following steps:

[0042] S1: The fixing frame 7 is installed at the film pulling-out position of the winding machine so that the film is placed above the rotating member 4. Since the connecting rod 5 is bent, when the connecting rod 5 is rotated until it is not in contact with the film, it is the minimum adjustable gear of the rotating ring 31. At this time, the flattening device has no flattening effect on the film. This state can be used for films without wrinkles.

[0043] S2: Rotate the rotating ring 31 until the bending part of the connecting rod 5 contacts the film. Continue to rotate the rotating ring 31 to make the bending part of the connecting rod 5 upward. Decide whether to continue rotating the rotating ring 31 according to the number of wrinkles on the film, until the bending part of the connecting rod 5 reaches the highest position. The connecting rod 5 lifts the film from the middle. At this time, the flattening area of ​​the film by the flattening device is the largest. After determining the angle, record the position of the pointer 32 corresponding to the scale line 2. Later, the wrinkle situation of the film can be directly adjusted to this angle by visually judging.
