They have the advantages of high capacity, low cost, and the ability to withstand high ripple current. The production process of aluminum electrolytic capacitors includes aluminum foil etching, cutting, winding, impregnation, etc. Among them, cutting includes cutting aluminum foil.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] See also Figure 1-Figure 10The aluminum foil cutting equipment for aluminum electrolytic capacitor production includes a slitting machine body 1, a knife shaft frame 2 connected to the slitting machine body 1, and a plurality of circular knives 3 connected to the knife shaft frame 2. A rectangular block 10 is arranged above the top of the circular knife 3. The number of the rectangular blocks 10 corresponds to the number of the circular knives 3. A knife groove 24 is opened in the rectangular block 10. The top of the circular knife 3 is located in the knife groove 24. Brackets 5 are fixedly connected to both sides of the mounting frame of the slitting machine body 1. A fixed shaft 4 is connected between the two brackets 5. The fixed shaft 4 is slidably connected to a mounting piece. The mounting piece is connected to the mounting piece. The tops of the rectangular blocks 10 are connected, blast grooves 25 are provided on both sides of the inner wall of the knife groove 24, a U-shaped blast channel 26 connected to the two blast grooves 25 is provided in the rectangular block 10, blast vents 15 are fixedly connected on both sides of the outer wall of the rectangular block 10, a blast duct 16 is connected between the blast vents 15 on both sides of each rectangular block 10, a blower 9 installed on the slitting machine body 1 is fixedly connected to the starting end of the blast duct 16, the air outlet of the blower 9 is fixedly connected to the blast duct 16, and a dust collection component is connected to the rectangular block 10.

[0035] The aluminum foil cutting equipment for aluminum electrolytic capacitor production in the present invention, when the circular knife 3 is cutting the aluminum foil in self-rotation, the knife groove 24 in the rectangular block 10 can just cover a part of the blade of the circular knife 3, and the inner wall of the knife groove 24 does not contact the circular knife 3. When the circular knife 3 generates heat during the self-rotation cutting movement, the blower 9 is turned on, and the blower 9 blows air into the blast tuyere 15 on the rectangular block 10 through the blast duct 16. The wind flow is then infused into the U-shaped blast channel 26 and the blast groove 25 through the blast tuyere 15. The wind flow is transmitted to the next rectangular block 10 through the blast tuyere 15 on the outer wall of the rightmost rectangular block 10 until multiple rectangular blocks 10 are blown by the wind flow. Since a plurality of blast grooves 25 are located on both sides of the inner wall of the knife groove 24, the blade of the circular knife 3 can be blown to achieve heat dissipation of the blade of the circular knife 3, thereby reducing the heat generated by the circular knife 3 when cutting the aluminum foil, thereby increasing the service life of the circular knife 3.

[0036] Through the cooperation between the knife groove 24, the U-shaped blast channel 26, the blast groove 25, the blast pipe 16 and the blower 9 in the rectangular block 10, the circular knife 3 can be located in the middle of the knife groove 24, and through the guidance of the blast groove 25, the wind flow is directly aimed at the blade position of the circular knife 3 for heat dissipation, thereby reducing the heat generated by the circular knife 3 when cutting aluminum foil, thereby increasing the service life of the circular knife 3.

[0037] As a preferred technical solution of the present invention, the dust suction component includes a suction fan 8, and suction grooves 23 are provided on both sides of the inner wall of the knife groove 24 in the rectangular block 10 below the blast groove 25. Two U-shaped suction channels 29 connected to the suction grooves 23 are provided in the rectangular block 10. Suction vents 17 connected to the suction grooves 23 are fixedly connected on both sides of the outer wall of the rectangular block 10. The ends of the suction vents 17 on the outer walls of both sides of each rectangular block 10 are connected to suction ducts 18, and the starting end of the suction duct 18 is fixedly connected to the outer side of the air outlet of the suction fan 8. A dust collection box 35 is detachably connected to one side of the suction fan 8, and the suction fan 8 is installed on the outer wall of the slitting machine body 1.

[0038] Specifically, when the circular knife 3 is working, in order to prevent the aluminum ash particles generated by the circular knife 3 when cutting the aluminum foil from affecting the flatness after cutting, the suction fan 8 can be turned on. The suction fan 8 generates negative pressure, so that the suction groove 23 in each rectangular block 10 sucks air to adsorb the aluminum ash particles on the blade of the circular knife 3. The suction grooves 23 on both sides of the inner wall of the knife groove 24 are connected through a U-shaped suction channel 29, so that the dust on both sides of the outer wall of the circular knife 3 can be adsorbed. Each rectangular block 10 is connected through the suction vent 17 and the suction duct 18, so that the dust adsorption of each circular knife 3 can be achieved.

[0039] Through the cooperation of the suction groove 23, the U-shaped suction channel 29 and the suction fan 8, the dust generated by the circular knife 3 during the aluminum foil cutting process can be adsorbed to achieve dust cleaning; at the same time, with the blowing of the blast groove 25, the dust on the blade of the circular knife 3 can be blown up first and then adsorbed by the suction groove 23. This cooperation can achieve a better dust cleaning effect.

[0040] The blower 9 and suction fan 8 here are existing mature technologies, so they are not described in detail here; it should be noted that the air blast vent 15 and the air suction vent 17 on the outer wall of the last rectangular block 10 away from the blower 9 and the suction fan 8 should be provided with sealing plugs to prevent air leakage from affecting the effect, and the sealing plug is an existing mature technology, so it is not described in detail here.

[0041] As a preferred technical solution of the present invention, arc plates 12 are rotatably connected on both sides of the outer wall of the rectangular block 10, the arc plates 12 are located on the outside of the circular knife 3, a U-shaped groove 13 for protecting the blade of the circular knife 3 is opened in the arc plate 12, and a limiting member is connected between the top of the arc plate 12 and the outer wall of the rectangular block 10.

[0042] Specifically, when the worker needs to adjust the spacing between the two circular knives 3, in order to facilitate the adjustment of the rectangular block 10, the worker can rotate the arc plate 12 so that the arc plate 12 is engaged with the outer wall of the circular knife 3, that is, the U-shaped groove 13 on the arc plate 12 is engaged with the circular knife 3, so that the rectangular block 10 and the circular knife 3 form a whole, so that when the circular knife 3 moves on the knife shaft frame 2, the rectangular block 10 can be driven to move synchronously, and there is no need to adjust the spacing of the rectangular blocks 10.

[0043] By setting a rotating arc plate 12 on the outer wall of the rectangular block 10, the arc plate 12 can be clamped with the circular knife 3, thereby facilitating the circular knife 3, the arc plate 12 and the rectangular block 10 to form a whole. When the circular knife 3 moves, the rectangular block 10 is driven to move without adjusting the spacing of the rectangular blocks 10.

[0044] As a preferred technical solution of the present invention, the mounting part includes two U-shaped blocks 11 which are sleeved on the outer wall of the fixed shaft 4, the bottom of the two U-shaped blocks 11 is fixedly connected with a slider 27, the top of the rectangular block 10 is provided with a slide groove 28 corresponding to the position of the slider 27, the fitting surfaces of the two U-shaped blocks 11 are provided with spring grooves 21, and the inner walls of the spring grooves 21 opposite to each other are fixedly connected with a tensioning spring 22, the outer walls of the two U-shaped blocks 11 are fixedly connected with a traction rope 14, and the other end of the traction rope 14 is fixedly connected to the outer wall of the arc plate 12.

[0045] Specifically, when the arc plate 12 is rotating, in order to make the U-shaped block 11 loose on the outside of the fixed shaft 4 and facilitate the rectangular block 10 to move with the movement of the circular knife 3, when the arc plate 12 is rotated to be engaged with the circular knife 3, the arc plate 12 will drive the traction rope 14 to pull the U-shaped block 11, and the slider 27 at the bottom of the U-shaped block 11 will slide on the top of the rectangular block 10, and at the same time, the two U-shaped blocks 11 will be separated from each other, and the tension spring 22 will be pulled. At this time, the U-shaped block 11 is loosened on the outside of the fixed shaft 4, and when the circular knife 3 moves, the rectangular block 10 also moves, and at the same time drives the U-shaped block 11 to move on the outside of the fixed shaft 4;

[0046] When the circular knife 3 needs to rotate, it only needs to rotate the arc plate 12 to expand the arc plate 12 to a certain angle. At this time, the traction rope 14 is loosened, and under the action of the tension spring 22, the two U-shaped blocks 11 are brought close to each other and clamped to the fixed shaft 4. When the U-shaped blocks 11 are close, the slider 27 at the bottom of the U-shaped block 11 slides in the slide groove 28, ensuring the stable movement of the U-shaped block 11.

[0047] After the arc plate 12 is rotated and unfolded to a certain angle, it is still located outside the blade of the circular knife 3, and can still protect the blade of the circular knife 3 during operation.

[0048] By rotating the arc plate 12 to engage with the circular knife 3, the two U-shaped blocks 11 on the fixed shaft 4 can be synchronously driven to separate, so that the U-shaped block 11 can be loosened on the fixed shaft 4, which makes it convenient for workers to achieve synchronous movement of the rectangular block 10 while moving the circular knife 3, further making the operation more convenient.

[0049] As a preferred technical solution of the present invention, the limit member includes a side block 19, a rotating shaft 30 is fixedly connected inside the side block 19, a rotating plate 20 is fixedly connected to the top outer wall of the arc plate 12, a connecting shaft 34 is fixedly connected to the top of the rotating plate 20, a rotating groove 32 is opened in the connecting shaft 34, a groove 33 is opened on the inner wall of the rotating groove 32, and an elastic strip 31 fixedly connected to the outer wall of the connecting shaft 34 is rotatably connected in the groove 33.

[0050] Specifically, in order to ensure the stability of the curved plate 12 in both states, when the curved plate 12 rotates, it will drive the connecting shaft 34 at the top of the rotating plate 20 to rotate in the rotating shaft 30 in the side block 19, and at the same time make the groove 33 rotate on the outside of the elastic strip 31. This arrangement can limit the rotation of the curved plate 12 in both states, ensuring that the position of the curved plate 12 after rotation will not change easily.

[0051] As a preferred technical solution of the present invention, the outer wall of the slitting machine body 1 is fixedly connected with a mounting plate 7, and the blower 9 and the suction fan 8 can be detachably connected to the top of the mounting plate 7. In this way, the blower 9 and the suction fan 8 can be easily installed.

[0052] As a preferred technical solution of the present invention, a mounting groove 6 is opened in the bracket 5, and the fixed shaft 4 is located in the mounting groove 6. The mounting groove 6 consists of a vertical groove and a horizontal groove, and the fixed shaft 4 is slidably connected in the vertical groove and the horizontal groove.

[0053] Specifically, when the circular knife 3 needs to be replaced as a whole, it is only necessary to lift the fixed shaft 4 so that the two ends of the fixed shaft 4 move up in the vertical grooves in the installation groove 6 and move laterally into the transverse grooves. In this way, the fixed shaft 4 can be moved up and fixed laterally in the transverse grooves, so that the several rectangular blocks 10 are away from the circular knife 3, thereby making it convenient for people to replace the circular knife 3.

[0054] As a preferred technical solution of the present invention, the cross-sections of the elastic strip 31 and the groove 33 are semicircular.

[0055] Specifically, such an arrangement can reduce a certain resistance when the groove 33 rotates on the outer side of the elastic strip 31 .

[0056] As a preferred technical solution of the present invention, the cross-sections of the slide groove 28 and the slider 27 are T-shaped or wedge-shaped.

[0057] Specifically, the T-shape or wedge-shape can ensure that the slider 27 will not fall out of the slide groove 28, and can provide the manufacturer with multiple choices.

[0058] As a preferred technical solution of the present invention, the cross section of the fixed shaft 4 is circular or rectangular.

[0059] Specifically, when the cross section of the fixed shaft 4 is circular or rectangular, it can ensure that the U-shaped block 11 can slide on the outside of the fixed shaft 4, and it can be convenient for the manufacturer to have multiple choices.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
