Technical Field

[0001] This utility model belongs to the field of solid capacitor coating, specifically, it relates to a device for uniformly coating the electrolyte of solid capacitors. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with specific functions.

[0003] Most existing coating apparatuses for solid capacitor electrolyte formation use a pump to pressurize and deliver the electrolyte to the coating head to coat the surface of the capacitor substrate. The coating process covers the substrate surface with the electrolyte. However, the pressure of the electrolyte during coating can affect the uniformity of the coating. Furthermore, when double-sided coating is required, the substrate with one side already coated needs to be coated again in the opposite direction, which can easily affect the coating efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for uniformly coating electrolyte in solid capacitor formation, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A device for uniformly coating a solid capacitor electrolyte is provided, comprising: a coating box, wherein an inlet and an outlet are respectively provided on both sides of the coating box; a first roller, a second roller, and a third roller are rotatably coupled inside the coating box; the second roller is located on one side of the first roller; the third roller is located on the lower side of the middle of the first roller and the second roller; a solid capacitor roll is sleeved between the first roller, the second roller, and the third roller; and a motor is provided on one side of the coating box, which is driven by the first roller, the second roller, and the third roller.

[0008] The coating box is equipped with two pipes, each with multiple discharge coating heads on one side, and a controller and a valve on one side of each pipe. The controller corresponds to the two valves, and a first connecting pipe connects the two pipes.

[0009] Optionally, a flow sensor is provided on one side of each of the two pipes; a display screen is provided on one side of the coating box, and the display screen is electrically connected to the two flow sensors.

[0010] Optionally, a paint box is provided at the bottom of the coating box, a second connecting pipe is provided between the paint box and the first connecting pipe, a filter plate is provided inside the paint box, and a water pump corresponding to the second connecting pipe is provided on one side of the paint box.

[0011] Optionally, the coating box is rotatably fitted with a first rotating shaft, a second rotating shaft, and a third rotating shaft that are respectively fixedly connected to the first rotating roller, the second rotating roller, and the third rotating roller. A first pulley is provided around the first rotating shaft, and a second pulley is provided at one end of the second rotating shaft. A first transmission belt is sleeved between the first pulley and the second pulley.

[0012] Optionally, a third pulley is provided at one end of the second rotating shaft, a fourth pulley is provided at one end of the third rotating shaft, a second transmission belt is sleeved between the third pulley and the fourth pulley, the output end of the motor is fixedly connected to the third rotating shaft, a support plate is provided on one side of the coating box, and the motor is mounted on the upper side of the support plate.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] The controller can regulate the flow rate of the electrolyte in the two pipes by controlling the valves, which keeps the pressure of the multiple coating heads stable.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-3 As shown, this embodiment provides a device for uniformly coating the electrolyte of a solid capacitor, including: a coating box 1, with an inlet 33 and an outlet 34 on both sides of the coating box 1, a first rotating roller 2, a second rotating roller 3 and a third rotating roller 4 rotatably fitted inside the coating box 1, the second rotating roller 3 being located on one side of the first rotating roller 2, and the third rotating roller 4 being located on the lower side of the middle of the first rotating roller 2 and the second rotating roller 3, the solid capacitor roll being sleeved between the first rotating roller 2, the second rotating roller 3 and the third rotating roller 4, and a motor 23 being provided on one side of the coating box 1 for transmission cooperation with the first rotating roller 2, the second rotating roller 3 and the third rotating roller 4;

[0025] The coating box 1 is equipped with two pipes 7. Multiple discharge coating heads 18 are provided on one side of each pipe 7. Controllers 8 and valves 10 are provided on one side of each pipe 7. The controllers 8 correspond to the two valves 10. A first connecting pipe 11 connects the two pipes 7.

[0026] The controller 8 can control the valve 10 to regulate the flow rate of the electrolyte in the two pipes 7, which can keep the coating pressure of the multiple discharge coating heads 18 stable. This reduces the possibility that the pressure of the electrolyte may affect the uniformity of the coating on the substrate surface. The multiple discharge coating heads 18 on one side of the two pipes 7 can coat both sides of the solid capacitor roll material that moves along the outside of the first roller 2, the second roller 3 and the third roller 4, reducing the need for two coatings on both sides of the roll material and thus improving the efficiency of coating the solid capacitor roll material.

[0027] like Figure 1-2As shown, in this embodiment, a flow sensor 9 is provided on one side of each of the two pipes 7; a display screen 6 is provided on one side of the coating box 1, and the display screen 6 is electrically connected to the two flow sensors 9.

[0028] The display screen 6 can display the flow rate of the liquid detected by the two flow sensors 9 in the two pipes 7, and send the control to the controller 8 to control the valve 10 to adjust the flow rate of the electrolytic liquid in the two pipes 7. This can keep the coating pressure of the multiple discharge heads 18 stable, thereby reducing the possibility that the pressure of the electrolyte may affect the uniformity of the coating on the substrate surface.

[0029] like Figure 1-2 As shown, in this embodiment, a coating box 13 is provided at the bottom of the coating box 1, a second connecting pipe 12 is provided between the coating box 13 and the first connecting pipe 11, a filter plate 17 is provided inside the coating box 13, and a water pump 14 corresponding to the second connecting pipe 12 is provided on one side of the coating box 13.

[0030] The collection box 13 can collect the electrolyte dripping from the capacitor roll after coating, reducing the waste of electrolyte.

[0031] like Figure 3 As shown, in this embodiment, the coating box 1 is rotatably fitted with a first rotating shaft 20, a second rotating shaft 19, and a third rotating shaft 21, which are respectively fixedly connected to the first rotating roller 2, the second rotating roller 3, and the third rotating roller 4. A first pulley 22 is provided around the first rotating shaft 20, and a second pulley 24 is provided at one end of the second rotating shaft 19. A first transmission belt 28 is sleeved between the first pulley 22 and the second pulley 24. A third pulley 30 is provided at one end of the second rotating shaft 19, and a fourth pulley 31 is provided at one end of the third rotating shaft 21. A second transmission belt 32 is sleeved between the third pulley 30 and the fourth pulley 31. The output end of the motor 23 is fixedly connected to the third rotating shaft 21. A support plate 29 is provided on one side of the coating box 1, and the motor 23 is located on the upper side of the support plate 29.

[0032] Through multiple discharge nozzles 18 on one side of the two pipes 7, the valve 10 is first opened by the controller 8. The dissolved liquid in the first connecting pipe 11 is sprayed out through the two pipes 7 from the multiple discharge nozzles 18. The motor 23 is started, and the output end of the motor 23 drives the third rotating shaft 21 to rotate. The rotation of the third rotating shaft 21 drives the third rotating roller 4 to rotate. The rotation of the third rotating shaft 21 drives the fourth pulley 31 to rotate. The rotation of the fourth pulley 31 drives the third pulley 30 to rotate through the second transmission belt 32. The rotation of the third pulley 30 drives the second rotating shaft 19 to rotate. The rotation of the second rotating shaft 19 drives the second rotating roller 3 to rotate. The rotation of the second rotating roller 3 drives the second rotating roller 3 to rotate. The second pulley 24 rotates, which in turn drives the first pulley 22 to rotate via the first transmission belt 28. The rotation of the first pulley 22 drives the first rotating shaft 20 to rotate, which in turn drives the first rotating roller 2 to rotate. This process coats both sides of the solid capacitor roll material that moves along the outer sides of the first rotating roller 2, the second rotating roller 3, and the third rotating roller 4. Multiple coating heads 18 can coat both sides of the solid capacitor roll material that moves along the outer sides of the first rotating roller 2, the second rotating roller 3, and the third rotating roller 4, reducing the need for two coatings on both sides of the roll material and thus improving the efficiency of coating the solid capacitor roll material.
