Description

Technical Field

[0001] This utility model generally relates to the field of capacitor technology, and specifically to a film marking device for aluminum electrolytic capacitors. Background Technology

[0002] The outer surface of the aluminum electrolytic capacitor is fitted with a thermoplastic insulating sleeve, and the insulating sleeve is printed with the capacitor product identification. The product identification on the insulating sleeve is formed by printing with an ink marking device. The marking process on the insulating sleeve is as follows: the product identification is printed with ink at each marking position on the insulating film roll in sequence. Then, the part of the insulating film with the product identification is placed on the site to air dry naturally. Finally, the dried insulating film is processed into multiple insulating sleeves, each with the product identification.

[0003] However, since the insulating film after the above-mentioned ink printing marks needs to be air-dried, the marking operation cycle of the insulating sleeve is not only long, but also requires a large drying area. In addition, manual winding and sorting of the dried insulating film is required, which increases the marking cost of the insulating sleeve. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a film marking device for aluminum electrolytic capacitors.

[0005] This application provides a film marking device for aluminum electrolytic capacitors, comprising:

[0006] frame;

[0007] A film conveying device is mounted on the frame and includes an unwinding roller and a take-up roller, with the take-up roller being rotatably mounted.

[0008] An ink marking device is installed in the conveying path of the film conveying device;

[0009] A drying device is provided, which is located in the conveying path of the film conveying device and downstream of the ink marking device along the film conveying direction. The drying device includes an air multiplier and outputs air through the air multiplier.

[0010] Furthermore, the film conveying device also includes a first guide roller, wherein the air outlet of the air drying device is positioned facing the bearing surface of the first guide roller.

[0011] Furthermore, the number of first guide rollers is several, and the several first guide rollers are arranged at intervals along a set direction, wherein the air drying device is movably arranged along the set direction.

[0012] Furthermore, the number of air-drying devices is several, and the several air-drying devices are arranged along the axial direction of the first guide roller.

[0013] Furthermore, the ink marking device includes a pressure roller, a printing plate roller, and an ink tray, with the ink tray located below the printing plate roller and the pressure roller located above the printing plate roller.

[0014] The aluminum electrolytic capacitor sleeve marking device provided in this application has an air drying device in the sleeve conveying path. The air drying device outputs air to the ink marking through an air multiplier, so that the ink marking printed on the sleeve can be dried online. This eliminates the need for the sleeve to be naturally dried in a drying area after printing the ink marking, reducing the sleeve marking operation time and the work site requirements. At the same time, it can also use a take-up roller to automatically rewind the air-dried sleeve online, eliminating the need for manual winding and reducing the sleeve marking cost. Attached Figure Description

[0015] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0016] Figure 1 This is a schematic diagram of the structure of the aluminum electrolytic capacitor film marking device provided in the embodiments of this application. Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] Please refer to the attached document. Figure 1This application provides a marking device for aluminum electrolytic capacitor sleeves, including a frame 100 and a sleeve conveying device, an ink marking device, and a drying device 170 disposed on the frame 100. The sleeve conveying device, comprising an unwinding roller 110 and a rewinding roller 140, is used to convey sleeves. The unwinding roller 110 is rotatably disposed on the frame 100 and is used to hold the sleeve roll (i.e., a rolled sleeve). The rewinding roller 140 is rotatably disposed on the frame 100 and is used to rewind the marked sleeve. The ink marking device and the drying device 170 are both disposed in the conveying path of the sleeve conveying device, with the drying device 170 located downstream of the ink marking device along the sleeve conveying direction. The ink marking device is used to print ink markings on the upper surface of the sleeve conveyed by the sleeve conveying device, and the drying device 170 is used to dry the ink markings on the sleeve conveying device. The air-drying device 170 includes a fan and an air multiplier. The air multiplier is located at the air outlet of the fan, and the air-drying device 170 outputs air through the air multiplier. Under the action of the air multiplier, the air-drying device 170 can draw in the surrounding air, enabling it to output a high airflow to the film surface. This allows for faster drying of the ink markings, achieving online processing of ink marking and drying. Furthermore, it features lower noise compared to traditional fans, reducing noise pollution.

[0019] In this embodiment, by sequentially setting an ink marking device and an air drying device 170 in the film conveying path, and by having the take-up roller 140 and the air drying device 170 output air to the ink marking through an air multiplier, the ink marking printed on the film can be dried online. This eliminates the need for the film to be naturally dried in a drying area after printing the ink marking, reducing the film marking operation time and the required work site. At the same time, the take-up roller 140 can also automatically rewind the air-dried film online without manual handling and rewinding, thus reducing the film marking cost.

[0020] The air multiplier mentioned above is an existing structure in the art, and will not be described in detail here. Preferably, the drying device 170 is a Dyson hair dryer (such as the HD15 model) with air multiplication function, which integrates the fan and air multiplier into one design, which not only has a large air volume, low noise and good drying effect, but also simplifies the structure of the drying device 170.

[0021] Both the unwinding roller 110 and the winding roller 140 can be driven by a motor to ensure that the winding speed of the film is consistent.

[0022] Optionally, the ink marking device includes a pressure roller 150, a printing plate roller 120, and an ink tray 160. The ink tray 160 is located below the printing plate roller 120, and the pressure roller 150 is located above the printing plate roller 120. The film passes between the pressure roller 150 and the printing plate roller 120. The ink tray 160 contains ink and is mounted on the frame 100. Both the printing plate roller 120 and the pressure roller 150 are rotatably mounted on the frame 100. The printing plate roller 120 transfers the ink marking onto the surface of the film, and the pressure roller 150 squeezes the film to improve the printing effect of the ink marking. The pressure roller 150 can be, but is not limited to, a rubber roller.

[0023] In some embodiments of this application, the film conveying device further includes a first guide roller 130 disposed on the frame 100, wherein the air outlet of the drying device 170 is disposed facing the bearing surface of the first guide roller 130, so that the film can be supported by the first guide roller 130 when it is blown by air, which helps to improve the drying effect and the stability of the film movement.

[0024] In some embodiments of this application, the number of first guide rollers 130 is several, and the several first guide rollers 130 are arranged at intervals along a set direction. The air drying device 170 is movably arranged along the set direction, thereby changing the air drying area of ​​the air drying device 170 to meet the needs of adjusting the air drying area and improving the practicality of the marking device.

[0025] Specifically, as shown in the attached document Figure 1 The frame 100 is also provided with a second guide roller 200, which is located between the printing plate roller 120 and the unwinding roller along the film conveying direction. There are two first guide rollers 130, and their set directions are shown by the arrows in the attached figure. The film released from the film roll located on the unwinding roller 110 passes sequentially through the second guide roller 200, the printing plate roller 120, and the two first guide rollers 130 and is wound up by the take-up roller 140. A guide rail 180 is provided above the first guide rollers 130. The guide rail 180 is fixedly connected to the frame 100. The guide rail 180 is provided with a mounting plate 190, and the mounting plate 190 and the guide rail 180 slide in a set direction. The drying device 170 is provided on the mounting plate 190.

[0026] Optionally, the number of drying devices 170 is one or more, wherein when the number of drying devices 170 is more than one, the drying devices 170 are arranged along the axial direction of the first guide roller 130.

[0027] Optionally, a sliding assembly is provided between the drying device 170 and the mounting plate 190, so that the drying device 170 can move axially along the first guide roller 130 relative to the mounting plate 190, thereby meeting the drying requirements for films of different widths. The sliding assembly includes a slide rail and a slider, one of which is disposed on the mounting plate 190 and the other is disposed on the drying device 170.

[0028] In some embodiments of this application, a friction roller assembly is also included. The friction roller assembly is located between two first guide rollers 130. The friction roller assembly includes a friction roller and a pressure roller arranged opposite each other, with the sleeve passing between them. Friction cleaning sleeves are provided at both ends of the friction roller. The flexible cleaning sleeves protrude from the outer peripheral surface of the friction roller, and a clearance gap is formed between the two friction cleaning sleeves to prevent the friction roller from contacting the ink markings on the sleeve. Under the squeezing action of the pressure roller, the friction cleaning sleeves perform friction cleaning on both ends of the sleeve to prevent ink residue from remaining at the edges of the sleeve, and also increase the roughness of the friction area to improve the adhesion strength at the sleeve joint. The material of the flexible cleaning sleeve can be, but is not limited to, corundum or similar materials.
