[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figure 1 As shown, a foil winding machine for reactor production according to one embodiment of this utility model includes a foil winding machine main unit 1, a driver 2, an air shaft 3, and a drum 4. The foil winding machine main unit 1 is wound with foil and an insulating material matching the foil. The driver 2 is located on one side of the foil winding machine main unit 1. The air shaft 3 is rotatably connected to the driver 2, and the driver 2 can drive the air shaft 3 to rotate. The drum 4 is mounted on the air shaft 3 and can rotate with the rotation of the air shaft 3. The foil and insulating material are alternately mounted on the drum 4. The driver 2 drives the air shaft 3 to rotate, causing the insulating material and foil to be wound into a foil coil.

[0028] like Figures 1-6 As shown, in order to improve cutting efficiency, the foil winding machine main unit 1 is equipped with a cutting component 5. The cutting component 5 can clamp the foil material and cut the foil material. The cutting component 5 includes a pair of first connecting arms 6, which are fixedly connected to both sides of the foil winding machine main unit 1. The first connecting arms 6 are detachably mounted on the foil winding machine main unit 1 by bolts 7.

[0029] like Figures 1-3 As shown, a foil pressing mechanism is fixedly connected to the first connecting arm 6, whose main function is to further improve the stability and precision of foil winding. Specifically, the foil pressing mechanism includes a pair of second connecting blocks 17, which are fixedly connected to the opposite surfaces of the two first connecting arms 6 respectively. A pressure roller 21 is rotatably connected to the second connecting block 17. The foil passes between the two pressure rollers 21 to achieve compression of the foil, which to some extent counteracts the slack tendency of the foil during operation.

[0030] like Figures 1-3 As shown, a pair of second connecting blocks 17 have second grooves 1702 on their opposite surfaces. A slider 20 matching the pressure roller 21 is installed within the second groove 1702. Mounting holes 2002 are formed on the opposite surfaces of the pair of sliders 20. A second bearing 22 matching the mounting hole 2002 is fixedly connected to the pressure roller 21, and the pressure roller 21 is rotatably connected to the mounting hole 2002 via the second bearing 22. The sliders 20 are slidably connected within the second grooves 1702 to control the distance between the two pressure rollers 21, thereby adapting to foil materials of different thicknesses.

[0031] Specifically, such as Figures 1-3 As shown, a through hole 1701 is provided on the upper end face of the second connecting block 17, extending from top to bottom through the second connecting block 17. A bidirectional screw 18 is rotatably connected inside the second connecting block 17. A first bearing 19 matching the through hole 1701 is fixedly connected to the bidirectional screw 18. A threaded hole 2001 matching the bidirectional screw 18 is provided on the slider 20, and the bidirectional screw 18 and the threaded hole 2001 are threadedly connected. To adjust the distance between the two pressure rollers 21, simply rotate the bidirectional screw 18 clockwise or counterclockwise. When rotating clockwise, the two pressure rollers 21 move in opposite directions to reduce the distance between them. When rotating counterclockwise, the two pressure rollers 21 move in opposite directions to increase the distance between them.

[0032] To facilitate the rotation of the bidirectional screw 18, a handwheel 1801 is fixedly connected to the upper end of the bidirectional screw 18. Since the second connecting block 17 is provided at both ends of the pressure roller 21, the two bidirectional screws 18 should be rotated simultaneously as much as possible during rotation to avoid one of them rotating and affecting the threaded engagement between the other bidirectional screw 18 and the threaded hole 2001.

[0033] Of course, the bidirectional screw 18 can also be driven by a motor in addition to being rotated by the handwheel 1801. Two motors can be driven simultaneously to achieve simultaneous rotation of both bidirectional screws 18. Generally, since the adjustment of the pressure roller 21 is not particularly frequent, in order to save costs, it is sufficient to have two people simultaneously rotate the handwheel 1801.

[0034] like Figures 1-6 As shown, a crossbar 8 is fixedly connected between a pair of first connecting arms 6. The crossbar 8 is generally fixed to the first connecting arms 6 by welding. A first sliding groove 801 is formed on the lower end face of the crossbar 8. An electric slider 9 that matches the first sliding groove 801 is slidably connected to the crossbar 8. The electric slider 9 can slide within the first sliding groove 801. Since the electric slider 9 is common knowledge to those skilled in the art, it will not be described in detail here.

[0035] like Figures 4-6 As shown, the lower end of the electric slider 9 is fixedly connected to the cutting machine 10. The cutting machine 10 can cut the foil material and polish the cut surface of the foil material to remove burrs. This reduces the possibility of the insulation material being scratched by burrs, which helps to ensure the overall quality and service life of the reactor.

[0036] like Figures 4-6As shown, the cutting machine 10 includes a second connecting arm 1001. A first cutter 1002 and a second cutter 1003 are fixedly connected to both ends of the second connecting arm 1001. A grinding block 11 is installed between the first cutter 1002 and the second cutter 1003. A grinding layer 13 for grinding the cut surface is installed on the grinding block 11. Specifically, the first cutter 1002 and the second cutter 1003 enable the electric slider 9 to cut the foil material during its first movement and also during its second return movement. That is, the cutting machine 10 does not need to perform a reset action after cutting, avoiding the time wasted on the return movement of the cutting machine 10.

[0037] Specifically, the grinding block 11 has a groove 1101 that matches the cutting surface. The groove 1101 is trapezoidal, and a rubber pad 12 is fixedly connected between the groove wall of the groove 1101 and the grinding layer 13. Due to the presence of the rubber pad 12, the grinding layer 13 and the foil are in an interference fit, which can increase the friction between the foil and the grinding layer 13, thereby improving the grinding effect to a certain extent.

[0038] Furthermore, the grinding block 11 is positioned between the first cutter 1002 and the second cutter 1003, so that the grinding block 11 can grind the cutting surface of the foil material regardless of whether it is the first movement or the return movement.

[0039] Preferably, buttons (not shown in the figure) for controlling the first cutter 1002 and the second cutter 1003 are fixedly connected to the opposite surfaces of a pair of first connecting arms 6. The two buttons are used to start and stop the first cutter 1002 and the second cutter 1003 respectively, so as to avoid the first cutter 1002 and the second cutter 1003 starting at the same time and reduce power consumption.

[0040] like Figures 4-6 As shown, debris is generated during the polishing process. In order to avoid debris falling on the insulating material as much as possible, a storage box 14 is installed at the lower end of the polishing block 11. The storage box 14 can cover the first cutter 1002 and the second cutter 1003. It has a deep storage groove to collect the fallen debris.

[0041] Specifically, such as Figures 4-6 As shown, a limiting groove 1102 is formed on the lower end face of the grinding block 11. A first connecting block 15 is fixedly connected to the middle of the storage box 14, and a connecting protrusion 16 that matches the limiting groove 1102 is fixedly connected to the first connecting block 15. The storage box 14 is installed in the limiting groove 1102 through the cooperation of the first connecting block 15 and the connecting protrusion 16, so as to realize the detachable installation of the storage box 14, so as to facilitate the handling of debris inside the storage box 14.

[0042] In use, the insulating material on the foil winding machine main unit 1 is wound onto the drum 4, and then the foil is passed through the pressure roller 21 and wound onto the drum 4, securing both to the drum 4. Then, the driver 2 is activated, and the air shaft 3 rotates, forming a foil coil. When foil needs to be cut, simply activate the electric slider 9 and the corresponding first cutter 1002 or second cutter 1003. During the movement of the electric slider 9, the first cutter 1002 or second cutter 1003 cuts the foil. Since the cutting point is located between the two pressure rollers 21 and is fixed by the pressure rollers 21, the cut foil is not easily loosened. In this state, the polishing layer 13 contacts the cutting surface, polishing the cutting surface to remove burrs. The debris falls into the storage box 14, which collects the debris.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
