Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic capacitor processing technology, and specifically to a foil cutting device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors are electrolytic capacitors with aluminum metal as the core material. Their basic structure consists of an aluminum cylinder (negative electrode), a liquid electrolyte, and a bent aluminum strip (positive electrode). An aluminum oxide film is formed on the surface of the positive electrode as the dielectric through DC voltage treatment. They have the characteristics of large capacity and low cost, but they have large leakage current and poor stability. They are mainly used for power supply filtering or low-frequency circuits.

[0003] In the processing of aluminum electrolytic capacitors, aluminum foil is required, and this foil needs to be cut by a foil cutting device.

[0004] Existing foil cutting machines for aluminum electrolytic capacitor processing can cut aluminum foil rolls as a whole, but this cutting method is very easy to cause wrinkles in the aluminum foil at the cut, and the aluminum foil cannot be separated after cutting.

[0005] To address the aforementioned technical issues, CN220218658U discloses a foil cutting machine slitting device for processing aluminum electrolytic capacitors. This device fixes the aluminum foil roll using a hanging coil, then passes the aluminum foil between the blade ring and the bottom roller, thus cutting the aluminum foil. Because this cutting method only cuts each point once, and because the aluminum foil is extremely thin, the cut aluminum foil will not contact the blade ring again, preventing wrinkles. The cut aluminum foil is then wound into a winding roll, allowing it to be placed separately for easy handling by workers.

[0006] The existing technology still has the following shortcomings: in actual use, the slit foil needs to be wound up by a winding component, and the winding process can easily cause the wound foil to loosen, resulting in wrinkles in the wound material. Utility Model Content

[0007] The purpose of this invention is to provide a foil cutting device for aluminum electrolytic capacitors, which has the advantages of stable and uniform foil winding, and makes the wound foil tight and neat, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a foil cutting device for aluminum electrolytic capacitors, comprising a base plate;

[0009] A foil cutting mechanism is provided at one end of the top of the base plate for cutting the foil, and a material-blocking mechanism is provided at the other end of the top of the base plate for blocking the material during winding.

[0010] The foil cutting mechanism includes:

[0011] A blade used for cutting foil to a preset width;

[0012] The material receiving mechanism includes:

[0013] An electric slide table is installed on the top of the base plate for adjusting the material support position. The top of the electric slide table is provided with a load-bearing component for elastic connection and a rolling component that contacts the foil.

[0014] Both ends of the bottom of the bearing component are provided with limiting components for sliding support of the bearing component.

[0015] Preferably, the carrier component includes:

[0016] A support is installed on the top of the moving end of the electric slide table. The inner side wall of the support is equipped with a connecting block for supporting the rolling assembly and a crossbar adapted to the connecting block. A spring is provided on the outer side of the crossbar for connecting the support and the connecting block.

[0017] Preferably, the scrolling component includes:

[0018] The bracket installed on the top of the connecting block and the abutment roller rotatably connected to the inner side wall of the bracket, with the bracket in contact with the top surface of the support.

[0019] Preferably, the limiting component includes:

[0020] A sliding rod and a matching sliding block are installed on the top of the base plate, with the top of the sliding block installed on the bottom of the support to provide sliding support for the support.

[0021] Preferably, the foil cutting mechanism includes:

[0022] A drive assembly for power output during foil cutting and a rotating assembly adapted to the drive assembly for rotary foil cutting.

[0023] Preferably, the driving component includes:

[0024] A motor for outputting to the rotating assembly and a support plate for supporting the motor are mounted on top of the base plate.

[0025] Preferably, the rotating assembly includes:

[0026] The rotating roller is installed on the inside of the support plate. The top and bottom of the rotating roller are provided with grooves and sliders that are adapted to the grooves.

[0027] Preferably, the top of the base plate is provided with a feeder for assisting in feeding foil, and the top of the base plate is also provided with a winding machine for winding the foil.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] This invention achieves the advantage of assisting in the winding of foil after slitting by setting up a material-stopping mechanism, so as to ensure the uniformity and neatness of the winding process and avoid loosening and wrinkles. The material-stopping roller that directly contacts the foil can be adjusted by using an electric slide table, as well as a crossbar, connecting block and spring that can be adapted to the winding process of the winding machine to elastically stop the material, so that after the material-stopping assistance winding is performed in the adjusted position, it can also elastically stop the material to assist in the winding operation of the foil, thereby meeting people's needs for material-stopping winding in the winding process.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides a foil cutting device for aluminum electrolytic capacitors, including a base plate 1;

[0038] A foil cutting mechanism 2 is provided at one end of the top of the base plate 1 for cutting foil, and a material abutting mechanism 4 is provided at the other end of the top of the base plate 1 for abutting the material during winding.

[0039] The foil cutting mechanism 2 includes:

[0040] Blade 26 is used to cut foil to a preset width;

[0041] Material receiving mechanism 4 includes:

[0042] An electric slide 41 is installed on the top of the base plate 1 for adjusting the material support position. The top of the electric slide 41 is provided with a bearing component for elastic connection and a rolling component that contacts the foil.

[0043] Both ends of the bottom of the load-bearing component are equipped with limiting components for sliding support of the load-bearing component.

[0044] Preferred;

[0045] like Figure 3 As shown, the carrier component includes:

[0046] A support 42 is installed on the top of the moving end of the electric slide table 41. The inner side wall of the support 42 is equipped with a connecting block 44 for supporting the rolling assembly and a crossbar 43 adapted to the connecting block 44. A spring 45 is provided on the outer side of the crossbar 43 for connecting the support 42 and the connecting block 44.

[0047] The position of the support 42 and its top components can be directly adjusted via the electric slide table 41, thereby adapting to the winding drum in the winding machine 5;

[0048] The elastic connecting block 44 allows the abutment roller 47 and the winding drum to make elastic contact, resulting in a certain elastic space during adjustment and winding, and always maintaining the same pressure to assist in the winding operation.

[0049] further;

[0050] like Figure 3 As shown, the scrolling component includes:

[0051] The bracket 46 is mounted on the top of the connecting block 44 and the abutting roller 47 is rotatably connected to the inner side wall of the bracket 46. The bracket 46 contacts the top surface of the support 42. The bracket 46 supports the abutting roller 47 and is rotatably connected to it, thereby assisting the winding drum in the foil winding operation.

[0052] Going a step further;

[0053] like Figure 3 As shown, the limiting component includes:

[0054] The slide rod 49 and the slide seat 48 that are adapted to the slide rod 49 are installed on the top of the base plate 1. The top of the slide seat 48 is installed on the bottom of the support 42, which provides sliding support for the support 42 and can assist it in sliding during adjustment.

[0055] During the winding process, the electric slide table 41 is directly started to indirectly drive the upper abutment roller 47 to approach the winding drum in the winding machine 5 until the wound foil is pressed between the abutment roller 47 and the winding drum. Then, the electric slide table 41 drives the abutment roller 47 to move slightly until the abutment roller 47 drives the connecting block 44 to slide on the outside of the crossbar 43 through the bracket 46 and squeeze the spring 45. At this time, the foil is elastically pressed to assist it in the winding operation.

[0056] After being cut, the foil passes through the bottom of the abutment roller 47 and is then wound up on the surface of the winding drum. As the diameter of the wound foil gradually increases, the spring 45 is pre-compressed, which increases the clamping force on the foil. At this time, the electric slide 41 works again, further driving the abutment roller 47 to move away from the foil. The abutment roller 47 is always in the original state of clamping the foil and slightly pressing the spring 45 until the winding is completed.

[0057] It is worth explaining;

[0058] like Figure 2 As shown, the foil cutting mechanism 2 includes:

[0059] A drive assembly for power output during foil cutting and a rotating assembly adapted to the drive assembly for rotary foil cutting.

[0060] in;

[0061] like Figure 2 As shown, the driving component includes:

[0062] The motor 22 for outputting to the rotating component and the support plate 21 for supporting the motor 22 are mounted on the top of the base plate 1. The support plate 21 can cut the foil before it is wound up. Several sets of blades 26 are provided as shown in the figure.

[0063] in addition;

[0064] like Figure 2 As shown, the rotating assembly includes:

[0065] The rotating roller 23 is installed inside the support plate 21. The top and bottom of the rotating roller 23 are provided with grooves 24 and sliders 25 that are adapted to the grooves 24. The rotating roller 23 realizes the transmission of rotational force and is used to slide and fix the grooves 24 and sliders 25. The sliders 25 are fixed to the inner wall of the grooves 24, i.e. the rotating roller 23, by bolts.

[0066] During the sliding process, the slider 25 slides inside the groove 24 and is adjusted to the required position by the added scale. Then, the corresponding blade 26 and slider 25 are added according to the required quantity and fixed with bolts. The rotating roller 23 is connected to the rotating end of the inner side of the support plate 21 by a flange. During slitting, the aluminum foil passes directly through the blade 26 and is driven by the motor 22 to rotate the blade 26 to slit the foil. Afterward, the aluminum foil passes between two sets of feeding cylinders, which are set up vertically. As shown in the figure, the upper feeding cylinder can be adjusted vertically, which can be adjusted by using the existing electric push rod.

[0067] at last:

[0068] like Figure 1 and 4 As shown, a feeder 3 for assisting in feeding foil is provided on the top of the base plate 1, and a winding machine 5 for winding the foil is also provided on the top of the base plate 1. The feeder 3 and the winding machine 5 respectively assist in feeding and winding the slit foil.

[0069] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
