Description

Technical Field

[0001] The present invention belongs to the technical field of capacitor film winding, and specifically refers to a capacitor film winding device. Background Art

[0002] During the production process of capacitor film, it will ultimately be wound into a wide-width roll shape. This winding does not have very strict requirements for tightness because when using the capacitor film to produce specific parts, it is necessary to cut the wide-width film roll into corresponding widths and then unfold and use it. Therefore, the tightness of the film winding does not affect its subsequent unfolding and use.

[0003] When the film roll is being wound, it is impossible to always be completely perpendicular to the reel. However, the deviation angle should not be too large, otherwise the film will shift horizontally towards one end of the reel during the winding process. But once this deviation occurs, it often continues. Therefore, it is necessary to sense this deviation during the film winding process and correct it in a timely manner. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention proposes a capacitor film winding device that can sense the deflection direction and deflection amplitude of the film body and automatically correct the angle of the winding roller. The present invention can sensitively sense and feedback the errors of the film body itself through a roller swing mechanism, and automatically and slowly adjust and correct the winding roller through a hydraulic linkage method. Moreover, the present invention also feeds back the progress of the winding process through a winding induction component. When the winding reaches a certain degree under the continuous rotation of the universal joint fork, the power transmission is automatically cut off and the film body is cut.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a capacitor film winding device, including a frame assembly, a roller swing mechanism, a winding induction component, a power transmission mechanism, and an automatic cutting mechanism. The frame assembly includes a first side plate, a second side plate, a connecting roller, and a film body.

The winding induction component is arranged on the first side plate, the power transmission mechanism is arranged on the first side plate, and the automatic cutting mechanism is arranged on the first side plate.

[0006] Further, the roller swing mechanism includes a hydraulic linkage component, a roller support component, and a roller deviation correction component. The hydraulic linkage component is arranged on the second side plate, the roller support component is arranged on the first side plate and the second side plate, and the roller deviation correction component is arranged on the roller support component.

[0007] The roller swing mechanism can not only sense the tightness on both sides of the film body, thereby providing feedback on the degree of deflection of the central axis of the film body; but also realize the deflection control of the winding roller through hydraulic linkage, so that the axis of the winding roller always remains perpendicular to the central axis of the film body, thereby avoiding the situation where the film body continues to deviate to one side during the process of being wound on the winding roller.

[0045] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0046] As Figures 1 to 12 shown, the present invention provides a capacitance film winding device, including a frame assembly 1, a roller swing mechanism 2, a winding induction assembly 3, a power transmission mechanism 4 and an automatic cutting mechanism 5. The frame assembly 1 includes a first side plate 6, a second side plate 7, a connecting roller 8 and a film body 9. The connecting roller 8 is rotatably arranged on the first side plate 6 and the second side plate 7, and the film body 9 is rollingly arranged on the connecting roller 8; the winding induction assembly 3 is arranged on the first side plate 6, the power transmission mechanism 4 is arranged on the first side plate 6, and the automatic cutting mechanism 5 is arranged on the first side plate 6.

[0047] The roller swing mechanism 2 includes a hydraulic linkage assembly 10, a roller support assembly 11 and a roller deviation correction assembly 12. The hydraulic linkage assembly 10 is arranged on the second side plate 7, the roller support assembly 11 is arranged on the first side plate 6 and the second side plate 7, and the roller deviation correction assembly 12 is arranged on the roller support assembly 11;

[0048] Through the roller swing mechanism 2, not only can the tightness on both sides of the film body 9 be sensed, so as to feedback the deflection degree of the central axis of the film body 9; and through the hydraulic linkage method, the deflection control of the winding roller 54 is realized, so that the axis of the winding roller 54 is always perpendicular to the central axis of the film body 9, thereby avoiding the situation that the film body 9 continuously deflects towards one side during the winding process on the winding roller 54.

[0049] The hydraulic linkage assembly 10 includes a hydraulic cylinder support 13, a hydraulic cylinder body 14, a telescopic push rod 15 and a hydraulic pipeline 16. The hydraulic cylinder support 13 is fixedly connected to the outside of the second side plate 7, the hydraulic cylinder body 14 is clamped in the hydraulic cylinder support 13, the telescopic push rod 15 is clamped and slidably arranged in the hydraulic cylinder body 14, and the hydraulic pipeline 16 is arranged between the two hydraulic cylinder bodies 14.

[0050] The roller support assembly 11 includes a fixed frame 17, a sliding frame 18, a rotating base 19 and a sliding bracket 20. The fixed frame 17 is fixedly connected to the first side plate 6, the sliding frame 18 is clamped and slidably arranged in the second side plate 7, the rotating base 19 is rotatably arranged in the fixed frame 17 and the sliding frame 18, and the sliding bracket 20 is fixedly connected to the telescopic push rod 15.

[0051] The two telescopic push rods 15 are both stationary in a semi-extended state in an initial state. Under the linkage action of the hydraulic pipeline 16, the two telescopic push rods 15 are extended and retracted alternately.

[0052] The roller correction assembly 12 includes a sensing roller 21, a rigid connecting rod 22, a roller support spring 23, a roller toggle spring 24 and a winding roller 54.

[0053] Because the horizontally placed telescopic push rod 15 and the winding roller 54 are flexibly connected via the second connecting rod 34, when the winding roller 54 is corrected, it will only have a tendency to deflect; the rigid connection between the longitudinally placed telescopic push rod 15 and the sliding frame 18 can improve the speed and sensitivity of the sensor feedback, and the flexible transmission between the transversely placed telescopic push rod 15 and the sliding frame 18 can not only realize the correction of the winding roller 54, but also make the process as slow and gentle as possible, thereby avoiding the embarrassing situation of partial folding of the film body 9.

[0054] The power transmission mechanism 4 includes a split universal joint assembly 30, a toggle clutch assembly 31 and an integral universal joint assembly 32. The split universal joint assembly 30 is connected to the winding roller 54, and the integral universal joint assembly 32 is connected to the split universal joint assembly 30. The toggle clutch assembly 31 is engaged and slidably arranged on the split universal joint assembly 30. The integral universal joint assembly 32 includes a universal joint yoke 40 and a cross shaft 41. The cross shaft 41 is rotatably arranged in the universal joint yoke 40.

[0055] The power transmission mechanism 4 transmits power through the universal joint, which can not only ensure the continuity of power transmission of the winding roller 54 during the swaying process, but also control the interruption and connection of power transmission through the sliding of the sliding sleeve 35; through the cooperation of the triangular portion 29 and the slope portion 42, after the film body 9 on the winding roller 54 is wound to a certain diameter, the power transmission can be interrupted by automatically shifting the sliding sleeve 35 by the sliding fork 37, thereby automatically stopping the rotation of the winding roller 54 without starting and stopping the motor.

[0056] The split universal joint assembly 30 includes a first connecting rod 33, a second connecting rod 34, a sliding sleeve 35 and a sleeve return spring 36. The first connecting rod 33 is arranged on the winding roller 54. The first connecting rod 33 and the second connecting rod 34 are rotatably connected. The sliding sleeve 35 is slidably arranged on the first connecting rod 33 and the second connecting rod 34 through a sliding groove. The sleeve return spring 36 is arranged between the sliding sleeve 35 and the second connecting rod 34. The fork frame part of the second connecting rod 34 and the universal joint fork frame 40 are connected through a cross shaft 41.

[0057] The shift clutch assembly 31 includes a sliding fork 37, a fork guide slide rod 38 and a fork return spring 39. The fork guide slide rod 38 is fixed to the outer side of the first side plate 6. The sliding fork 37 is slidably arranged on the fork guide slide rod 38. The sliding fork 37 is provided with a slope portion 42 matching the fork return spring 39. The fork return spring 39 is arranged between the disc portion of the fork guide slide rod 38 and the sliding fork 37.

[0058] The automatic cutting mechanism 5 includes a sliding cutting component 43 and a cutting locking component 44. The sliding cutting component 43 includes a circular fixed shaft 45, a sliding blade 46 and an elastic element 47. The circular fixed shaft 45 is fixedly connected to the first side plate 6 and the second side plate 7. The circular fixed shaft 45 is provided with a through groove portion 52. The sliding blade 46 is engaged and slidably arranged in the through groove portion 52. A locking block 53 is provided on the sliding blade 46. One end of the elastic element 47 is arranged on the second side plate 7, and the other end of the elastic element 47 is arranged on the sliding blade 46. The cutting locking component 44 is arranged on the inner side of the first side plate 6.

[0059] By moving the limit baffle 49 by the long connecting rod 27, when the film body 9 wound on the winding roller 54 reaches a certain diameter, the sliding blade 46 can be automatically released to complete the cutting of the film body 9.

[0060] The cutting locking assembly 44 includes a sliding buckle 48, a limiting baffle 49, a spring bottom plate 50 and a baffle return spring 51. The sliding buckle 48 is fixedly connected to the inner side of the first side plate 6, the limiting baffle 49 is slidably engaged in the sliding buckle 48, the spring bottom plate 50 is fixedly connected to the first side plate 6, and the baffle return spring 51 is arranged between the limiting baffle 49 and the spring bottom plate 50.

[0061] The winding sensing assembly 3 includes a sensing lever 25, a lever return spring 26 and a long connecting rod 27. The sensing lever 25 is slidably arranged in the first side plate 6. The sensing lever 25 is provided with an arc portion 28 on the inner side of the first side plate 6. The sensing lever 25 is provided with a triangular portion 29 on the outer side of the first side plate 6. The lever return spring 26 is arranged between the sensing lever 25 and the first side plate 6. The long connecting rod 27 is fixedly connected to the sensing lever 25.

[0062] The arc portion 28 can sense the diameter of the winding roller 54 after winding, and the power transmission mechanism 4 can be unlocked and controlled by the push of the long connecting rod 27; setting the arc portion 28 at one end close to the fixed frame 17 can not only shorten the spatial distance between the winding sensing component 3, the power transmission mechanism 4, and the automatic cutting mechanism 5, but also minimize the error caused by the deflection of the winding roller 54.

[0063] like Figure 13 As shown, the dotted line b is the central axis of the winding roller 54, and the dotted line a is the central axis of the film body 9. Under normal circumstances, the straight lines a and b are perpendicular to each other. When a deviates to the dotted line c, b also needs to deviate to the dotted line d with O as the center to keep the central axis of the film body 9 and the winding roller 54 perpendicular to each other to avoid lateral deviation during the winding process.

[0064] During specific use, the winding roller 54 is designed as a quick-release structure. After the winding roller 54 is installed, the film body 9 is first wound around the winding roller 54, and then the universal joint fork 40 is driven by an external mechanism to rotate the winding roller 54. The winding roller 54 will continue to reel in and wind the film body 9 during the rotation process.

[0065] Since the film body 9 will inevitably have errors, and the film body 9 cannot be limited from both sides like rigid materials, if the central axis of the film body 9 deviates, the film body 9 will move laterally in the direction of the deflection during the winding process. The present device can automatically correct this problem.

[0066] If the film body 9 deviates due to its own error, the tightness of the two sides of the film body 9 will become different. If the side close to the sliding frame 18 is relatively loose, one end of the sensing roller 21 will deflect longitudinally under the elastic force of the roller support spring 23. At this time, the sliding frame 18 located on the sensing roller 21 slides up and extends the telescopic push rod 15 out of the hydraulic cylinder body 14. At this time, the transmission fluid in the horizontal hydraulic cylinder body 14 will enter the vertical hydraulic cylinder body 14 through the hydraulic pipe 16, so the horizontal telescopic push rod 15 will retract;

[0067] According to the above-mentioned offset direction, the central axis of the film body 9 actually deflects toward the direction where the first side plate 6 is located. At this time, through the retraction of the horizontally placed telescopic push rod 15, a lateral force can be applied to the winding roller 54 through the sliding bracket 20 and the roller toggle spring 24, so that the winding roller 54 has a tendency to deflect toward the direction where the connecting roller 8 is located. Under the action of this thrust, the winding roller 54 will deflect to an angle perpendicular to the film body 9;

[0068] The rigid connection between the longitudinal telescopic push rod 15 and the sliding frame 18 can improve the speed and sensitivity of the sensor feedback, while the flexible transmission between the transverse telescopic push rod 15 and the sliding frame 18 can not only realize the deviation correction of the winding roller 54, but also make the process as slow and gentle as possible, thereby avoiding the embarrassing situation of partial folding of the film body 9.

[0069] The external mechanism transmits power through the universal joint yoke 40. If the external mechanism is not a separate motor, the rotation and stop of the external mechanism often cannot be freely controlled according to the requirements of the winding process. Therefore, for the winding process, the universal joint yoke 40 is continuously rotated;

[0070] During the winding process of the winding roller 54 , its diameter continues to increase, and the diameter of the winding roller 54 can be sensed by the arc portion 28 , and the sensing lever 25 can be pushed to slide by the winding roller 54 .

[0071] When the diameter of the winding roller 54 increases to a certain extent, the sensing lever 25 pushes the sliding fork 37 away from the first side plate 6 through the triangular portion 29, and the sliding fork 37 overcomes the elastic force of the sleeve return spring 36 to shift the sliding sleeve 35. After the sliding sleeve 35 slides away from the first connecting rod 33 and the second connecting rod 34 from the state of being connected, the rotation of the second connecting rod 34 cannot drive the first connecting rod 33 to rotate, thereby realizing power interruption;

[0072] At the same time, the long connecting rod 27 also contacts the restriction of the locking block 53 by pushing the limit baffle 49. After being unlocked, the sliding blade 46 slides from one end of the circular fixed shaft 45 to the other end of the circular fixed shaft 45 under the elastic force of the elastic element 47, and the cutting of the film body 9 is completed in the process.

[0073] After the cutting is completed, the winding roller 54 is removed as a whole and replaced with a new winding roller 54, and then the sliding blade 46 is pulled back to reset to carry out the next winding cycle.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0075] The above description of the present invention and its implementation manners is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
