Description

Technical Field

[0001] The present invention relates to the technical field of capacitor winding, and particularly to a metallized film capacitor winding machine. Background Art

[0002] The usual method for manufacturing a thin film capacitor is to wind an aluminum or other metal foil as an electrode and a plastic film together after overlapping them. However, there is another manufacturing method for thin film capacitors called metallized film, in which a very thin layer of metal is vacuum-evaporated onto a plastic film as an electrode. In this way, the thickness of the electrode foil can be saved, and the volume per unit capacitance of the capacitor can be reduced. Therefore, it is easier to make a thin film capacitor small in size and large in capacitance.

[0003] When processing a capacitor, the film roll conveying track on the winding machine generally has a tension device for tightening the tension of the film during transportation. During the process of film roll consumption and the operation of the winding machine, the roll gradually becomes smaller, and thus the tension applied by the tension device also changes, resulting in insufficient tension during film transportation, and wrinkles or insufficient adhesion in the overlap of the electrode and the film, thereby causing the production quality of the capacitor to be unable to be guaranteed. Therefore, improvement is needed. Summary of the Invention

[0041] To make the above objects, features, and advantages of the present invention more obvious and understandable, the specific implementation manner of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0042] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0043] Example, refer to Figures 1 to 11 , which is the first embodiment of the present invention. This embodiment provides a metallized film capacitor winding machine, which can realize the function of automatically correcting the tension while providing the tension of the electrode roll and the film roll, and can also limit the tension value. It includes a tensioning component 100, which includes a main body component 101, and a tension component 102 fixed on the upper and lower sides of the end face of the main body component 101. It also includes a track component 103 fixed in the middle of the tension component 102, and an expansion component 104 rotating at the end of the track component 103. The expansion component 104 is adapted to the tension component 102, and the expansion component 104 can drive the tension component 102 to expand;

[0044] A trigger component 200, which includes an intermittent component 201 fixed on the main body component 101, and a torsion component 202 fixed at the end of the intermittent component 201. The torsion component 202 is connected to the expansion component 104. The intermittent component 201 can be driven by the main body component 101 to intermittently trigger the torsion component 202 to drive the expansion component 104 to operate;

[0045] Adjusting component 300, which includes an elastic component 301 that moves within the track component 103, and a ratchet component 302 that slides at the end of the elastic component 301. The ratchet component 302 is connected to the track component 103 and the expansion component 104. It also includes an adjusting component 303 that slides within the ratchet component 302. When the expansion component 104 operates, it drives the elastic component 301 to cooperate with the track component 103 for compression, and after the operation of the expansion component 104 is completed, it is limited by the ratchet component 302.

[0046] Specifically, as Figure 2 shown in [reference], the main body component 101 includes a winding machine 101a, and drive shafts 101b that rotate at the upper and lower ends of the end face of the winding machine 101a. The drive shafts 101b have drive ends inside the winding machine 101a. It also includes a material roll 101c that is pivotally connected to the outer wall of the drive shaft 101b, and a support roller 101d that rotates on the inner side of the end face of the winding machine 101a corresponding to the material roll 101c. It also includes a polymerization roller 101e that rotates in the middle of the end face of the winding machine 101a. During use, the material on the material roll bypasses through the inner side of the support roller 101d, and after passing through the tension component 102, it is guided to the polymerization roller 101e. Thus, the materials on the two material rolls 101c on both sides can overlap.

[0047] Furthermore, as Figure 6 shown in [reference], the tension component 102 includes a fixed frame 102a fixed to the left side of the end face of the winding machine 101a corresponding to the support roller 101d. The fixed frame 102a is provided with sliding grooves 102b on both sides at one end of the winding machine 101a. It also includes a tension roller 102c that slides on both sides of the fixed frame 102a. The material of the material roll 101c is supported by the right tension roller 102c and then wound crosswise to the left tension roller 102c.

[0048] Furthermore, as Figure 7 shown in [reference], the track component 103 includes a fixed tube 103a fixed to the middle of the fixed frame 102a. The inner wall of the fixed tube 103a is provided with two spiral grooves 103b. The two spiral grooves 103b are arranged oppositely on the inner wall of the fixed tube 103a, and a rotating ring 103c that rotates on the outer wall of the fixed tube 103a. When the material of the material roll 101c passes through the tension component 102, the material needs to pass through the rotating ring 103c.

[0049] Furthermore, as Figure 8 shown in [reference], the expansion component 104 includes a receiving tube 104a that rotates at one end of the fixed tube 103a where the winding machine 101a is located, and a drive disk 104b fixed to the end of the receiving tube 104a. An arc-shaped groove 104c is provided on the end face of the drive disk 104b corresponding to the sliding groove 102b. The angle of the arc-shaped groove 104c is the same as that of the spiral groove 103b. It also includes a slider 104d that slides within the arc-shaped groove 104c. The slider 104d is connected to the tension roller 102c.

[0050] Further, as shown in Figure 9 , the intermittent component 201 includes an intermittent gear 201a fixed to the main body component 101. The intermittent gear 201a is fixed to the outer wall of the drive shaft 101b in the main body component 101. Only a part of the intermittent gear 201a has teeth, and a pinion gear 201b is movably connected to the bottom of the intermittent gear 201a. When the teeth of a part of the intermittent gear 201a mesh with the pinion gear 201b, the pinion gear 201b can be driven to rotate half a turn.

[0051] Further, as shown in Figure 9 , the torsion component 202 includes a transmission disc 202a fixed to the center of the pinion gear 201b, and a torsion spring 202b fixed to the end face of the transmission disc 202a. The transmission disc 202a and the torsion spring 202b are both located inside the receiving tube 104a. The torsion spring 202b is connected to the expansion component 104, and the torsion spring 202b is fixed to the receiving tube 104a in the expansion component 104.

[0052] Further, as shown in Figure 10 , the elastic force component 301 includes a force-receiving disc 301a movably connected to the inner wall of the fixed tube 103a, and an orbital block 301b fixed to the outer wall of the force-receiving disc 301a. The number of the orbital blocks 301b is adapted to the spiral groove 103b, and the orbital block 301b is adapted to the spiral groove 103b. The orbital block 301b slides inside the spiral groove 103b. It also includes a large spring 301c fixed between the force-receiving disc 301a and the fixed tube 103a. The torsion force of the torsion spring 202b is greater than the elastic force of the large spring 301c.

[0053] Further, as shown in Figure 10 , 11 , the ratchet component 302 includes a transmission block 302a sliding inside the force-receiving disc 301a. The transmission block 302a is connected to the expansion component 104, and the transmission block 302a is fixed to the receiving tube 104a in the expansion component 104. It also includes ratchet teeth 302b sliding on both sides of the transmission block 302a. An inclined groove 302c is provided at the side end of the ratchet teeth 302b. It also includes a small spring 302d fixed between the two ratchet teeth 302b. It also includes a ratchet ring 302e movably connected to the outside of the ratchet teeth 302b. The ratchet ring 302e is connected to the track component 103, and the ratchet ring 302e is fixed to the fixed tube 103a in the track component 103.

[0054] Further, as shown in Figure 10 , 11Among them, the adjusting component 303 includes a threaded pipe 303a that is movably connected to the end of the track component 103. The threaded pipe 303a is threadedly connected to the fixed pipe 103a in the track component 103, and a round rod 303b that is movably connected to the inner wall of the threaded pipe 303a. The round rod 303b penetrates through the ratchet component 302 and is fixedly connected to a trigger block 303c. The round rod 303b penetrates through the transmission block 302a in the ratchet component 302. A triangular groove 303d is provided at the end of the trigger block 303c. The triangular groove 303d is adapted to the ratchet component 302. The triangular groove 303d is adapted to the inclined groove 302c on the ratchet tooth 302b in the ratchet component 302. During use, by twisting the threaded pipe 303a, the distance between the end of the threaded pipe 303a and the force-receiving disc 301a can be adjusted. Thus, the distance by which the force-receiving disc 301a presses the large spring 301c is limited. From this, the compression distance of the large spring 301c can be known, and thus the elastic force of the spring can be obtained. Thus, the elastic force limit of the large spring 301c can be preset in advance. And when it is necessary to release the limit of the ratchet component 302, by pressing the round rod 303b to drive the trigger block 303c close to the ratchet tooth 302b. Thus, the triangular groove 303d will press the inclined groove 302c, causing the two ratchet teeth 302b to move inward to press the small spring 302d, and the ratchet tooth 302b will also disengage from the limit with the ratchet ring 302e.

[0055] In use, by twisting the threaded tube 303a, the distance between the end of the threaded tube 303a and the force-receiving disc 301a can be adjusted. Thus, the distance by which the force-receiving disc 301a presses the large spring 301c is limited. From this, the compression distance of the large spring 301c can be known, and thus the elastic force of the spring can be obtained. Then, the elastic force limit of the large spring 301c can be preset in advance. Subsequently, when the material roll 101c on the drive shaft 101b operates, the drive shaft 101b will drive the intermittent gear 201a to rotate. When a part of the teeth of the intermittent gear 201a meshes with the small gear 201b, it will drive the small gear 201b to rotate half a turn. The small gear 201b will drive the transmission disc 202a to twist the torsion spring 202b, and the torsion force of the torsion spring 202b will drive the receiving tube 104a to rotate. The receiving tube 104a will drive the transmission block 302a, the force-receiving disc 301a, and the track block 301b to rotate. When the track block 301b rotates in the spiral groove 103b, it will drive the force-receiving disc 301a to press the large spring 301c. During this process, the transmission block 302a will drive the ratchet tooth 302b to rotate, and the ratchet tooth 302b can rotate on the ratchet ring 302e in cooperation with the small spring 302d. When the large spring 301c cannot be pressed, the ratchet assembly 302 will stop and be limited. At the same time, the receiving tube 104a will drive the drive disc 104b to rotate. When the drive disc 104b rotates, the arc groove 104c will drive the slider 104d and the tension roller 102c to expand, thus completing the tension reset on one side. And each time for calibration, it can stop when the force-receiving disc 301a touches the threaded tube 303a. This is the preset tension range. Thus, the tension of the material roll 101c can be calibrated within a specific time. When it is necessary to reset the whole, by pressing the round rod 303b to drive the trigger block 303c to approach the ratchet tooth 302b, the triangular groove 303d will press the inclined groove 302c, causing the two ratchet teeth 302b to move inward to press the small spring 302d, and the ratchet teeth 302b will also disengage from the limit with the ratchet ring 302e. Thus, the large spring 301c can press the force-receiving disc 301a and the subsequent structures to reset.

[0056] In summary, through the tensioning component 100, the triggering component 200, and the adjusting component 300, while providing the tension for the electrode roll and the film roll, it has the function of automatically resetting the tension degree, and the required tension force can be preset in advance. Thus, it solves the problem that during the operation of the electrode roll and the film roll, the tension degree is unstable, resulting in the inability to guarantee the processing accuracy and quality of the capacitor.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
