Description

Technical Field

[0001] This utility model relates to the field of ceramic transfer roller technology, and in particular to a ceramic transfer roller device for vacuum evaporation with a circulating coolant cooling system. Background Technology

[0002] In the capacitor manufacturing industry, vacuum evaporation of metallized thin films is a crucial manufacturing process. This process involves heating, melting, and vaporizing metals such as zinc and aluminum in a vacuum environment, then physically depositing them onto the surface of a thin film to form the metallized layer required for the capacitor. In the vacuum evaporation process of capacitor safety films, the ceramic transfer roller is a core component, and its performance directly affects the pattern accuracy and product yield of the metallized film. On the one hand, the ceramic transfer roller is very close to the shielding oil heating roller, and the heat radiation from the oil roller causes the transfer roller's temperature to rise. On the other hand, the ceramic transfer roller rotates at high speed during normal evaporation production, generating a large amount of frictional heat, further exacerbating the heating situation. Excessively high temperatures can severely affect the amount of shielding oil deposited on the transfer roller, thus affecting the overall performance. The clarity of the printed pattern on the safety film is affected. When the temperature of the transfer roller is too high, the fluidity of the oil film changes during the transfer process, resulting in uneven oil film distribution. This ultimately leads to metal residue within the safety film pattern, severely affecting the electrical performance of the capacitor. To solve this problem, existing technologies typically use an external support to circulate coolant to cool the ceramic transfer roller. However, these cooling methods have limited effectiveness and cannot effectively control the temperature of the transfer roller. Especially under long-term continuous production, the temperature of the transfer roller will gradually rise, eventually leading to a decline in product quality. At the same time, the substrate film is inconvenient to replace, resulting in a long downtime for the equipment during replacement. Summary of the Invention

[0003] To overcome the above shortcomings, this utility model provides a ceramic transfer roller device for vacuum evaporation with a circulating coolant cooling system, which aims to improve the problems of the general cooling effect of existing ceramic transfer roller devices and the long downtime caused by the difficulty in replacing the substrate film.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic transfer roller device for vacuum evaporation with a circulating coolant cooling system, comprising a base, a mounting frame fixedly connected to the middle of the base, a safety film screen roller rotatably connected to the middle of the mounting frame, a ceramic transfer roller body disposed on the upper front side of the mounting frame, mounting blocks fixedly connected to the left and right sides of the upper part of the base, a heating oil roller rotatably connected to the opposite side of the mounting blocks, an L-shaped frame fixedly connected to the left rear side of the mounting frame, a mounting roller rotatably connected inside the L-shaped frame, a coating drum fixedly connected to the outside of the mounting roller, a substrate film disposed on the outside of the coating drum, a cylinder fixedly connected to the upper right rear side of the base, a support block fixedly connected to the output end of the cylinder, a limit component disposed on the upper right side of the base for limiting the support block, and a cooling component disposed in the middle of the mounting frame for cooling the ceramic transfer roller body.

[0005] As a further description of the above technical solution:

[0006] The limiting component includes a support frame, which is fixedly connected to the right side of the shaft base. An installation groove is provided on the upper right side of the support frame, and a slider is slidably connected inside the installation groove. A limiting block is slidably connected inside the support frame. A connecting block is fixedly connected to the front side of the limiting block, and a handle is fixedly connected to the front side of the connecting block. Telescopic columns are fixedly connected to the upper and lower sides of the rear side of the connecting block, and a return spring is sleeved on the outer side of the telescopic column.

[0007] As a further description of the above technical solution:

[0008] The cooling assembly includes a coolant channel, which is fixedly connected to the middle of the ceramic transfer roller body. One end of the coolant channel is provided with a coolant inlet and a coolant outlet.

[0009] As a further description of the above technical solution:

[0010] The end of the mounting roller furthest from the L-shaped frame is rotatably connected inside the support block.

[0011] As a further description of the above technical solution:

[0012] One end of the reset spring is fixedly connected to the connecting block, and the other end of the reset spring is fixedly connected to the support frame.

[0013] As a further description of the above technical solution:

[0014] The slider is fixedly connected to the support block, and the rear side of the limiting block is slidably connected inside the mounting groove.

[0015] As a further description of the above technical solution:

[0016] Both the coolant inlet and coolant outlet are connected to the infusion pump.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by pulling the handle, the connecting block is moved. The connecting block pulls the reset spring and the telescopic column, which in turn move the limit block to slide away from the mounting groove. Then, the starting cylinder is controlled to move the support block to move away from the mounting roller. The support block moves the slider inside the mounting groove. Finally, the coating drum is pulled to move away from the mounting roller. This makes it easy to replace the substrate film in the ceramic transfer roller device and reduces the downtime of the device.

[0019] 2. In this utility model, the circulating coolant enters the coolant channel inside the ceramic transfer roller body through the coolant inlet, absorbs the heat generated by the ceramic transfer roller body, and is discharged from the coolant outlet to form a cooling cycle. During this process, the coolant effectively removes the heat from the ceramic transfer roller body, maintaining its temperature within the range required by the process, thereby ensuring the clarity of the safety film pattern, avoiding the problem of metal residue caused by excessive temperature, and improving the electrical performance of the capacitor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 2-4 This utility model provides an embodiment of a ceramic transfer roller device for vacuum evaporation deposition with a circulating coolant cooling system, comprising a base 1, a mounting frame 2 fixedly connected to the middle of the base 1, a safety film screen roller 6 rotatably connected to the upper middle of the mounting frame 2, a ceramic transfer roller body 3 disposed on the upper front side of the mounting frame 2, mounting blocks 11 fixedly connected to the left and right sides of the upper part of the base 1, a heating oil roller 12 rotatably connected to the opposite side of the mounting blocks 11, an L-shaped frame 7 fixedly connected to the left rear side of the mounting frame 2, a mounting roller 8 rotatably connected inside the L-shaped frame 7, and a coating main drum 9 fixedly connected to the outside of the mounting roller 8. A substrate film 10 is provided on the outside of the main drum 9. A cylinder 21 is fixedly connected to the upper right rear side of the base 1. A support block 22 is fixedly connected to the output end of the cylinder 21. The end of the mounting roller 8 away from the L-shaped frame 7 is rotatably connected to the inside of the support block 22. A cooling component is provided in the middle of the mounting frame 2 for cooling the ceramic transfer roller body 3. The cooling component includes a coolant channel 23, which is fixedly connected to the middle of the ceramic transfer roller body 3. One end of the coolant channel 23 is provided with a coolant inlet 4 and a coolant outlet 5. Both the coolant inlet 4 and the coolant outlet 5 are connected to a pump.

[0028] During the vacuum evaporation process of the metallized film of the capacitor, the heated oil roller 12 heats a specific shielding oil to form an oil mist. This oil mist evaporates at high temperature and deposits on the surface of the ceramic transfer roller body 3. Subsequently, the ceramic transfer roller body 3 contacts the safety film screen roller 6, uniformly transferring the oil film onto the surface of the safety film screen roller 6. Then, the safety film screen roller 6 is pressed onto the coating drum 9, further transferring the oil film onto the substrate film 10 to form a safety film pattern. To ensure the stability and accuracy of the entire process, circulating coolant enters the coolant channel 23 inside the ceramic transfer roller body 3 through the coolant inlet 4. After absorbing the heat generated by the ceramic transfer roller body 3, the coolant is discharged through the coolant outlet 5, forming an effective cooling cycle. This effectively removes the heat generated by the ceramic transfer roller body 3, maintaining its temperature within the process requirements, ensuring the clarity of the safety film pattern, avoiding metal residue problems caused by excessive temperature, thereby improving the electrical performance of the capacitor and ensuring the high quality and stability of the capacitor.

[0029] Reference Figures 1-3A limiting component is provided on the upper right side of the base 1 to limit the support block 22. The limiting component includes a support frame 13, which is fixedly connected to the right side of the base 1. An installation groove 14 is provided on the upper right side of the support frame 13. A slider 15 is slidably connected inside the installation groove 14. A limiting block 16 is slidably connected inside the support frame 13. A connecting block 17 is fixedly connected to the front side of the limiting block 16. A handle 18 is fixedly connected to the front side of the connecting block 17. Telescopic columns 19 are fixedly connected to the upper and lower sides of the rear side of the connecting block 17. A return spring 20 is sleeved on the outside of the telescopic column 19. One end of the return spring 20 is fixedly connected to the connecting block 17, and the other end of the return spring 20 is fixedly connected to the support frame 13. The slider 15 is fixedly connected to the support block 22. The rear side of the limiting block 16 is slidably connected inside the installation groove 14.

[0030] When the substrate film 10 needs to be replaced, the operator first pulls the handle 18, which moves the connecting block 17. The connecting block 17 then pulls the return spring 20 and the telescopic column 19, simultaneously causing the limit block 16 to slide and disengage from the mounting groove 14. Next, the operator controls the starting cylinder 21 to push the support block 22, causing it to disengage from the mounting roller 8. The support block 22 then drives the slider 15 to slide inside the mounting groove 14, ultimately pulling the coating drum 9 to smoothly disengage from the mounting roller 8. This ensures that the ceramic transfer roller device can efficiently and conveniently replace the substrate film 10, effectively reducing equipment downtime and improving production efficiency.

[0031] Working principle: During the vacuum evaporation process of capacitor metallization film, the heating oil roller 12 heats a specific shielding oil to form an oil mist that evaporates and deposits on the surface of the ceramic transfer roller body 3. The ceramic transfer roller body 3 contacts the safety film screen roller 6, transferring the oil film onto the safety film screen roller 6. Then, the safety film screen roller 6 presses against the coating drum 9, transferring the oil film onto the substrate film 10 to form a safety film pattern. Simultaneously, circulating coolant enters the coolant channel 23 inside the ceramic transfer roller body 3 through the coolant inlet 4, absorbs the heat generated by the ceramic transfer roller body 3, and is discharged from the coolant outlet 5 to form a cooling cycle. During this process, the coolant effectively removes the heat from the ceramic transfer roller body 3, maintaining its temperature within the process range. Within the required range, the clarity of the safety film pattern is ensured, while avoiding metal residue problems caused by excessive temperature, thus improving the electrical performance of the capacitor. When the substrate film 10 needs to be replaced, the handle 18 is pulled to move the connecting block 17. The connecting block 17 pulls the reset spring 20 and the telescopic column 19 to simultaneously move the limit block 16 to slide away from the mounting groove 14. Then, the starting cylinder 21 is controlled to move the support block 22 to move away from the mounting roller 8. The support block 22 moves the slider 15 inside the mounting groove 14. Finally, the coating drum 9 is pulled to detach it from the mounting roller 8. This makes it easy to replace the substrate film 10 in the ceramic transfer roller device and reduces the downtime of the device.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
