[0007] A counterweight block is slidably connected to the transmission plate, and an insert rod is slidably connected inside the counterweight block.

[0008] Preferably, a magnet is installed inside the insertion rod, and a spring is installed on the surface of the transmission plate.

[0010] Preferably, the rotating plate is fixedly connected to the L-shaped rod, the telescopic rod is rotationally connected to the box body, and the sliding block is slidably connected to the transmission plate.

[0011] Preferably, a guide dust removal device is provided on the surface of the transmission plate, and the guide dust removal device includes an arc-shaped plate, an impeller is rotatably connected inside the arc-shaped plate, and a protrusion is fixedly connected to the surface of the transmission plate.

[0015] A method for producing an anode foil production device for an aluminum electrolytic capacitor comprises the following steps:

[0016] Step 1: Adjust the number of counterweights according to the thickness of the anode foil, insert the rod into the corresponding counterweight and push the counterweight and the counterweight above it upwards, so that the magnet in the rod and the external magnet attract each other, thereby limiting the position of the rod and the counterweight;

[0017] Step 2: At this time, the transmission plate will move under the pressure of the remaining counterweight blocks, and the transmission plate will drive the briquetting machine to press on the surface of the anode foil, making the anode foil straight;

[0018] Step 3: The fan rotates to blow air into the box, and the baffle guides the wind direction to blow air toward the two outlets of the box;

[0019] Step 4: The roller will then roll up the straightened and dust-free anode foil.

[0020] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0021] 1. The method for producing anode foil for aluminum electrolytic capacitors is to adjust the number of counterweights according to the thickness of the anode foil, insert a rod into the corresponding counterweight and push it and the counterweights above it upward, so that the magnet in the rod and the external magnet attract each other, thereby limiting the position of the rod and the counterweight. At this time, the transmission plate will move under the pressure of the remaining counterweights, and the transmission plate will drive the briquetting machine to press on the surface of the anode foil, so that the anode foil is straightened. Compared with the straightening by two rollers, this method is more convenient.

[0022] 2. The anode foil production method for the aluminum electrolytic capacitor can blow air into the box through the rotation of the fan, and the baffle will guide the wind direction to blow air to the two outlets of the box, thereby blowing out the dust at the outlets to prevent external dust from entering and falling on the anode foil. At the same time, the slider can be driven to move upward by pushing the counterweight block upward, and the upward movement of the slider will drive the telescopic rod to rotate, and the telescopic rod will drive the L-shaped rod to move downward, and the L-shaped rod will pull the rotating plate to open. At this time, the wind blown by the fan will be blown onto the anode foil through the guidance of the rotating plate, thereby blowing away the dust on the surface of the anode foil.

[0023] 3. The anode foil production method for aluminum electrolytic capacitors is that the wind passing through the rotating plate will blow on the arc plate, and the wind will be guided by the arc plate to blow toward the outlet, so that the blown dust will be blown out directly from the outlet, and at the same time, the blowing wind will drive the impeller to rotate, and the rotation of the impeller will knock the bump, so that the bump drives the transmission plate to generate a small vibration, and the vibration can help the dust on the surface of the anode foil to fall off.

[0024] 4. The anode foil production method for aluminum electrolytic capacitors is as follows: when the device is wound up, the slider will reset and drive the upper inner magnet to reset together. At this time, the inner magnet will be flush with the outer magnet and push the outer magnet to move outward through repulsion. The outer magnet will drive the limit block to move so that it clamps the fan, which can prevent the fan from blowing when the next anode foil is placed after the end, thereby affecting the placement of the next anode foil.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0033] A method for producing anode foil for aluminum electrolytic capacitors, such as Figure 1-Figure 6 As shown, it includes a stretching device, which is installed on the inner wall of the top of the box body 1. The inner wall of the box body 1 is rotatably connected to two rollers 2, and the two rollers 2 are connected through the anode foil transmission. A fan 3 with a relatively slow rotation speed is installed on the surface of the box body 1. The stretching device also includes:

[0034] A transmission plate 4, both sides of which are slidably connected to the inner wall of the top of the box body 1, a pressing block 8 for maintaining the tension of the anode foil is fixedly connected to the bottom of the transmission plate 4, and an external magnet 7 is movably installed on the top of the box body 1;

[0035] The counterweight block 9 has a surface that is slidably connected to the inner wall of the transmission plate 4 , and the inner wall of the counterweight block 9 is slidably connected to an insertion rod 10 for lifting the counterweight block 9 .

[0036] A magnet is installed on the inner wall of the insertion rod 10, and the magnet is magnetically attracted to the external magnet 7. Springs are installed on both sides of the transmission plate 4, and the other end of the spring is fixedly connected to the inner wall of the top of the box body 1. The number of counterweights 9 is adjusted according to the thickness of the anode foil. The insertion rod 10 is inserted into the corresponding counterweight 9 and the counterweights 9 above it are pushed upward, so that the magnet in the insertion rod 10 and the external magnet 7 attract each other, thereby limiting the insertion rod 10 and the counterweight 9. At this time, the transmission plate 4 will move under the pressure of the remaining counterweights 9, and the transmission plate 4 will drive the briquetting machine 8 to press on the surface of the anode foil, so that the anode foil is straightened. Compared with the straightening of the two rollers 2, this method is more convenient, and while ensuring the surface tension of the anode foil by slightly pressing it to straighten it, the briquetting machine 8 can also smooth the axis edge.

[0037] The inner wall of the box body 1 is provided with two control isolation devices 5, which are respectively located on both sides of the transmission plate 4. The control isolation device 5 includes a slider 51. The front and rear parts of the slider 51 are rotatably connected to a telescopic rod 52 through a connecting rod. The surface of the telescopic rod 52 away from the slider 51 is rotatably connected to an L-shaped rod 53. The inner wall of the box body 1 is fixedly connected to a baffle 54 for guiding wind, and the interior of the baffle 54 is rotatably connected to a rotating plate 55 for opening the baffle 54.

[0038] The lower surface of the rotating plate 55 is fixedly connected to the end of the L-shaped rod 53 away from the telescopic rod 52, and the side of the telescopic rod 52 close to the transmission plate 4 is rotatably connected to the surface of the box body 1. The surface of the slider 51 is slidably connected to the inner wall of the transmission plate 4, and the bottom of the slider 51 is in contact with the top of the counterweight 9. The fan 3 can blow air into the box body 1. At the same time, the baffle 54 will guide the wind direction so that it blows air to the two outlets of the box body 1, and then blow out the dust at the outlet to prevent external dust from entering and falling on the anode foil. At the same time, the slider 51 can be driven to move up according to the upward push of the counterweight 9. The upward movement of the slider 51 will drive the telescopic rod 52 to rotate, and the telescopic rod 52 will drive the L-shaped rod 53 to move down. The L-shaped rod 53 will pull the rotating plate 55 to open. At this time, the wind blown out by the fan 3 will be blown on the anode foil through the guidance of the rotating plate 55, so as to blow away the dust on the surface of the anode foil.

[0039] A guide dust removal device 6 is provided on both sides of the transmission plate 4. The guide dust removal device 6 includes an arc plate 61. The inner wall at the top of the arc plate 61 is rotatably connected to an impeller 62. Both sides of the transmission plate 4 are fixedly connected to protrusions 63.

[0040] The arc center of the arc plate 61 is fixedly connected to the two sides of the transmission plate 4, and the surface of the impeller 62 is in contact with the surface of the protrusion 63. The wind passing through the rotating plate 55 will blow on the arc plate 61, and the wind will be guided to the outlet through the arc plate 61, so that the blown dust is directly blown out from the outlet. At the same time, the blown wind will drive the impeller 62 to rotate, and the rotation of the impeller 62 will hit the protrusion 63, so that the protrusion 63 drives the transmission plate 4 to generate a small vibration, and the vibration can help the dust on the surface of the anode foil to fall off.

[0041] An anti-blow device is provided on the side of the outer magnet 7 away from the transmission plate 4, and the anti-blow device includes an elastic sheet 71. A limiting recess block 72 is fixedly connected to the side of the outer magnet 7 away from the transmission plate 4, and an inner magnet 73 is fixedly connected to the top of the slider 51, and the inner magnet 73 and the outer magnet 7 magnetically repel each other.

[0042] The side of the elastic sheet 71 close to the transmission plate 4 is fixedly connected to the surface of the outer magnet 7, and the side of the elastic sheet 71 away from the outer magnet 7 is fixedly connected to the upper surface of the box body 1. The inner wall of the limiting concave block 72 contacts the surface of the fan 3. When the device is wound up, the slider 51 will reset and drive the upper inner magnet 73 to reset together. At this time, the inner magnet 73 will be flush with the outer magnet 7 and push the outer magnet 7 to move outward through repulsion. The outer magnet 7 will drive the limiting concave block 72 to move so that it clamps the fan 3, which can prevent the fan 3 from blowing when the next anode foil is placed after the end, thereby affecting the placement of the next anode foil.

[0043] Working principle: the number of counterweights 9 is adjusted according to the thickness of the anode foil, and the rod 10 is inserted into the corresponding counterweight 9 to push the counterweight 9 and the counterweight 9 above it upward, so that the magnet in the rod 10 and the external magnet 7 attract each other, and then the rod 10 and the counterweight 9 are limited. At this time, the transmission plate 4 will move under the pressure of the remaining counterweights 9, and the transmission plate 4 will drive the briquetting machine 8 to press on the surface of the anode foil, so that the anode foil is straightened. Compared with the straightening of the two rollers 2, this method is more convenient, and the surface tension of the anode foil is ensured by slight pressure, and the briquetting machine 8 can also flatten the axis edge;

[0044] The fan 3 rotates to blow air into the box 1, and the baffle 54 guides the wind direction so that it blows air toward the two outlets of the box 1, thereby blowing out the dust at the outlets to prevent external dust from entering and falling on the anode foil. At the same time, the slider 51 can be driven to move upward by pushing the counterweight 9 upward, and the upward movement of the slider 51 will drive the telescopic rod 52 to rotate, and the telescopic rod 52 will drive the L-shaped rod 53 to move downward, and the L-shaped rod 53 will pull the rotating plate 55 to open. At this time, the wind blown by the fan 3 will be guided by the rotating plate 55 and blow on the anode foil, thereby blowing away the dust on the surface of the anode foil.

[0045] The wind passing through the rotating plate 55 will blow on the arc plate 61, and the arc plate 61 will guide the wind to the outlet, so that the dust blown down will be blown out directly from the outlet. At the same time, the wind will drive the impeller 62 to rotate, and the rotation of the impeller 62 will knock the protrusion 63, so that the protrusion 63 drives the transmission plate 4 to generate a small vibration, and the vibration can help the dust on the surface of the anode foil to fall off;

[0046] When the device is wound up, the slider 51 will reset and drive the inner magnet 73 above to reset together. At this time, the inner magnet 73 will be flush with the outer magnet 7 and push the outer magnet 7 to move outward through repulsion. The outer magnet 7 will drive the limiting concave block 72 to move so that it clamps the fan 3, which can prevent the fan 3 from blowing when the next anode foil is placed after the end, thereby affecting the placement of the next anode foil. Example

[0047] A method for producing an anode foil production device for an aluminum electrolytic capacitor comprises the following steps:

[0048] Step 1: Adjust the number of counterweights 9 according to the thickness of the anode foil, insert the rod 10 into the corresponding counterweight 9 and push the counterweight 9 and the counterweight 9 above it upward, so that the magnet in the rod 10 and the external magnet 7 attract each other, thereby limiting the rod 10 and the counterweight 9;

[0049] Step 2: At this time, the transmission plate 4 will move under the pressure of the remaining counterweight 9, and the transmission plate 4 will drive the briquetting machine 8 to press on the surface of the anode foil, so that the anode foil is straightened;

[0050] Step 3: The fan 3 rotates to blow air into the box 1, and the baffle 54 guides the wind direction so that it blows air toward the two outlets of the box 1;

[0051] Step 4: Roller 2 will then roll up the straightened and dust-free anode foil.

[0052] The present invention provides a method for producing an anode foil for an aluminum electrolytic capacitor. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention. All components not specified in this embodiment can be implemented using existing technologies.
