Description

Technical Field

[0001] The invention belongs to the technical field of capacitor film production, and in particular relates to a capacitor film production device and a method thereof. Background Art

[0002] Capacitor film is a key material used to make capacitors. It is usually made of insulating materials with high permittivity and can form a space for charge storage between electrodes. The main function of capacitor film is to store charge under the action of electric field and release charge when needed, so it plays the role of energy storage and regulation in electronic circuits. Capacitor film has the following characteristics: high dielectric constant. The dielectric constant of capacitor film materials is high, which means that they can store more charge under a given electric field; good insulation. Capacitor film must have good electrical insulation to prevent charge from leaking directly through the film, thereby effectively storing electrical energy; stable chemical properties. Capacitor film materials need to have chemical stability to ensure that their performance will not change significantly during manufacturing and application; mechanical strength: capacitor film should also have a certain mechanical strength to withstand mechanical stress during manufacturing and installation; the material and preparation method of capacitor film will affect its performance and application range. Common capacitor film materials include polymers, ceramics and metal oxides. Preparation methods include thermal evaporation, sputtering, chemical vapor deposition and solution coating.

[0003] After searching, it was found that a Chinese patent with the authorization announcement number "CN112038123B" disclosed a polypropylene capacitor film production device, including a frame, a guide roller, a clamping mechanism, a storage roller and a stand. A rotating rod is passed through one side of the stand, a rotating disk is fixed at one end of the outer side of the rotating rod, a first bevel gear is fixed at the end of the rotating rod away from the rotating disk, a second bevel gear is meshed at the top of the first bevel gear, a screw is fixed at the top of the second bevel gear, an internal threaded tube is rotated at the top of the screw, a connecting plate is fixed at the top of the internal threaded tube, and support rods are fixed symmetrically on both sides of the top of the connecting plate; by installing a rotating disk on one side of the stand, the height adjustment of the annular cutting tool is convenient and fast, and the adjustment speed is fast, saving time, improving the cutting work efficiency, thereby improving the production efficiency of polypropylene capacitor film, by installing shock-absorbing columns at the four corners of the bottom end of the frame, the shock-absorbing spring shrinks through its own deformation, reducing the vibration amplitude, thereby ensuring the stability and production efficiency of the device, and improving the service life of the device. The above patent uses a cutting knife and the adjustment of the cutting knife to achieve the cutting of capacitor film.

[0004] However, the above technical solution does not have a drying effect when used. Since the capacitor film needs to be dried to remove residual solvent and moisture when it is produced, the above patent requires drying the film after cutting when used, which is cumbersome and delays the film production efficiency.

[0061] As a preferred solution of the present invention, it also includes a cutting mechanism, which is arranged on the support plate to achieve cutting of the film.

[0062] A method for producing a capacitor film comprises the following steps:

[0063] S1. Crushing: First, the raw materials are added into the feed hopper, and the servo motor is started. The output end of the servo motor rotates the first rotating shaft through the meshing of the two first spur gears, and the first rotating shaft rotates the third rotating shaft through the oblique meshing of the two second bevel gears. The third rotating shaft transmits power through the second I-shaped wheel and the second belt, so that one of the crushing shafts rotates. Due to the meshing of the two fourth spur gears, the two crushing rollers rotate inward at the same time to achieve the crushing of the raw materials, so that the raw materials enter the mixing box after being crushed;

[0064] S2, mixing and extruding: at the same time, the output shaft of the servo motor drives the fourth rotating shaft to rotate, and the fourth rotating shaft drives the fifth rotating shaft to rotate through the transmission of the first I-shaped wheel and the first belt, and the fifth rotating shaft drives the second spur gear on its surface to rotate. Since the two third spur gears are meshed with the second spur gears, the two third spur gears rotate synchronously, thereby driving the two mixing shafts to rotate, so as to achieve mixing of the crushed raw materials. After mixing, the raw materials are transported to the extruder through the mixing shaft, and are extruded into a film through the extruder, and enter the stretching mechanism;

[0065] S3, stretching: the film passes through the upper surface of the upper guide roller and then to the lower surfaces of the two lower guide rollers, and finally passes between the two clamping rollers, is clamped by the clamping rollers and stretched to one side, and is rotated by the second rotating shaft in the second transmission assembly, and the second rotating shaft is rotated by the oblique meshing of the two first bevel gears, and then the third I-shaped wheel and the third belt are used to transmit power, so that one of the clamping shafts rotates, and the clamping shaft drives the fifth spur gear on its surface to rotate, and the two fifth spur gears are meshed with each other, so that the two clamping rollers rotate inward at the same time to achieve clamping and stretching of the film;

[0066] S4. Drying and cutting: The heat generated by the servo motor, mixing box and extruder is collected in the collector box to heat up the air in the collector box. At the same time, the third bevel gear in the transmission assembly is used to rotate the sixth shaft. When the sixth shaft rotates, it drives the small I-shaped wheel to rotate. The small I-shaped wheel drives the large I-shaped wheel to rotate through the fourth belt to realize the rotation of one of the seventh shafts. Since multiple sixth spur gears are meshed in sequence, multiple seventh shafts rotate, and then drive the fan blades to rotate, blowing the hot air in the collector box through the air outlet onto the film, which can achieve effective drying of the film, and then the film is cut by the cutting mechanism.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] 1. In the present invention, the heat collecting box can not only serve as a base for support, but also collect the heat generated by the servo motor, the mixing box and the extruder, and heat the air by the heat to achieve the drying of the film. Not only does it make the service life of the driving parts less likely to be reduced due to excessive temperature, but the generated heat can also be recycled, which is not only convenient, but also reduces the consumption of resources and has broad application prospects.

[0069] 2. In the present invention, the raw materials can be crushed by the crushing assembly, so that the raw materials entering the mixing box for mixing are not easy to produce large particles and be stuck in the mixing box, so as to achieve a better mixing effect.

[0070] 3. In the present invention, the diameters of the small I-wheel and the large I-wheel in the transmission mechanism are different, so that when the small I-wheel drives the large I-wheel through the fourth belt, the rotation speed of the large I-wheel is effectively reduced, thereby reducing the rotation speed of multiple seventh rotating shafts. In this way, the heat in the collector box can fully heat up the space, so that the air blown out by the fan blades has a higher temperature, which can effectively achieve the drying of the film.

[0071] 4. In the present invention, the power of the servo motor can be effectively transmitted to the crushing assembly, mixing mechanism, stretching mechanism and fan blades through the transmission assembly. Not only is the structure ingenious, but it also reduces the investment of resources and capital, so that other parts can also complete the operation.

[0072] 5. In the present invention, the film can be guided to the vicinity of the air outlet through the stretching mechanism. However, since the film is stretched and the fan blades rotate at a low speed, the film is not easily blown, but can be effectively dried. BRIEF DESCRIPTION OF THE DRAWINGS

[0146] Example 2

[0147] This embodiment 2 also provides a method for producing a capacitor film, which is used to further explain and illustrate the working principle of the capacitor film production device provided in the above embodiment 1, as follows:

[0148] A method for producing a capacitor film comprises the following steps:

[0149] S1. Crushing: First, the raw materials are added into the feed hopper 201, and the servo motor 6 is started. The output end of the servo motor 6 rotates the first rotating shaft 701 through the meshing of the two first spur gears 7. The first rotating shaft 701 rotates the third rotating shaft 706 through the oblique meshing of the two second bevel gears 704. The third rotating shaft 706 transmits power through the second I-shaped wheel 903 and the second belt 904, so that one of the crushing shafts 9 rotates. Since the two fourth spur gears 902 are meshed, the two crushing rollers 901 rotate inward at the same time to achieve the crushing of the raw materials, so that the raw materials enter the mixing box 2 after being crushed;

[0150] S2, mixing and extruding: At the same time, the output shaft of the servo motor 6 drives the fourth rotating shaft 8 to rotate, and the fourth rotating shaft 8 drives the fifth rotating shaft 803 to rotate through the transmission of the first I-shaped wheel 801 and the first belt 802, and the fifth rotating shaft 803 drives the second spur gear 804 on its surface to rotate. Since the two third spur gears 805 are meshed with the second spur gear 804, the two third spur gears 805 rotate synchronously, thereby driving the two mixing shafts 202 to rotate, so as to achieve mixing of the crushed raw materials. After mixing, the raw materials are transported to the extruder 3 through the mixing shaft 202, and are extruded into a film through the extruder 3 and enter the stretching mechanism;

[0151] S3, stretching: the film passes through the upper surface of the upper guide roller 402 and then to the lower surfaces of the two lower guide rollers 403, and finally passes between the two clamping rollers 405, and is clamped by the clamping rollers 405 and stretched to one side, and is rotated by the second rotating shaft 705 in the second transmission assembly, and the second rotating shaft 705 is rotated by the oblique meshing of the two first bevel gears 703, and then the third I-shaped wheel 11 and the third belt 111 are used to transmit power, so that one of the clamping shafts 4051 rotates, and the clamping shaft 4051 drives the fifth spur gear 112 on its surface to rotate, and the two fifth spur gears 112 are meshed with each other, so that the two clamping rollers 405 rotate inward at the same time to achieve clamping and stretching of the film;

[0152] S4. Drying and cutting: The heat generated by the operation of the servo motor 6, the mixing box 2 and the extruder 3 is collected in the heat collecting box 1, so that the air in the heat collecting box 1 is heated up. At the same time, the third bevel gear 121 in the transmission assembly is used to rotate the sixth rotating shaft 12. When the sixth rotating shaft 12 rotates, it drives the small I-shaped wheel 122 to rotate. The small I-shaped wheel 122 drives the large I-shaped wheel 124 to rotate through the fourth belt 123 to realize the rotation of one of the seventh rotating shafts 13. Since the multiple sixth spur gears 133 are meshed in sequence, the multiple seventh rotating shafts 13 are rotated, and then the fan blades 131 are driven to rotate, and the hot air in the heat collecting box 1 is blown onto the film through the air outlet 132, which can achieve effective drying of the film, and then the film is cut by the cutting mechanism.

The first rotating shaft (701) rotates the third rotating shaft (706) through the oblique meshing of the two second bevel gears (704). The third rotating shaft (706) transmits power through the second I-shaped wheel (903) and the second belt (904), so that one of the crushing shafts (9) rotates. Due to the meshing of the two fourth spur gears (902), the two crushing rollers (901) rotate inward at the same time to crush the raw material, so that the raw material enters the mixing box (2) after being crushed.
