Examples

Referring to fig. 1 to 3, an embodiment of the present application provides a multi-cavity cartridge mechanism 100, comprising: a frame 10 and at least two doctor blade cartridge mechanisms 20;

at least two blade cartridge mechanisms 20 are spaced apart along the length of the frame 10.

Specifically, as shown in fig. 1, in the present embodiment, the number of the blade cartridge mechanisms 20 is two, one blade cartridge mechanism 20 is disposed on one side in the length direction of the frame 10, and the other blade cartridge mechanism 20 is disposed on the other side opposite to the one side in the length direction of the frame 10. It should be noted that fig. 1 also shows the plate roller 200 for reference, and only one part of the plate roller 200 which is matched with the doctor blade cartridge mechanism 20 is shown in fig. 1, and the middle part which is not required to be matched is not shown.

Two blade box mechanisms 20 are respectively arranged at two opposite sides of the frame 10, so that when the isolating membrane is coated at the side, the middle part of the isolating membrane, which is not required to be coated, can be kept clean and is not polluted by slurry.

That is, the position between the two blade box mechanisms 20 is the blank area of the isolation film, and since the areas to be coated are coated by the corresponding blade box mechanisms 20, the slurry is not coated on the blank area, but is controlled at the position of the blade box mechanism 20, and the problem that the blank area of the isolation film is polluted can be effectively overcome no matter whether the edge coating or the zebra coating of the isolation film is performed.

It will be appreciated that the present embodiment shows only two schematic views of the doctor blade cartridge mechanism 20, showing only one alternative arrangement. When zebra coating is required, more blade cartridge mechanisms 20 may be further added.

Referring to fig. 1, in particular, the frame 10 includes a fixing mechanism 11, the fixing mechanism 11 is provided with an adjusting portion, the scraper box mechanisms 20 are assembled in the adjusting portion, and the adjusting portion can adjust the horizontal distance between two adjacent scraper box mechanisms 20. By designing the adjustment section, the position of the blade cartridge mechanism 20 can then be adjusted to suit the coating requirements, depending on the width and location of the blank area that is to be left.

Alternatively, referring to fig. 4, the fixing mechanism 11 is provided with a long hole 112 as an adjusting portion, the length direction of the long hole 112 is the same as the length direction of the frame 10, and a mounting bracket 21 (mentioned below) is engaged with the long hole 112 and the position of the long hole 112 in the length direction is adjustable. The mounting frame 21 can move along the length direction of the long hole 112, when the position of the mounting frame 21 needs to be adjusted, the positioning process in the height direction of the fixing mechanism 11 can be omitted, and only the position of the mounting frame 21 needs to be adjusted, so that the distance between two adjacent scraper box mechanisms 20 meets the requirement of the width of a blank area to be left. Alternatively, the mounting bracket 21 is fixed to the elongated hole by screw fitting. Alternatively, a plurality of mounting holes may be provided at intervals on the fixing mechanism 11 as the adjustment portions, and then the blade cartridge mechanism 20 may be mounted at different mounting holes according to the pitch requirement.

Further, the upper portion of the mounting frame 21 is provided with mounting adjusting blocks 211, the side profile of the mounting frame 21 is L-shaped, and each mounting adjusting block 211 can move up and down relative to the fixing mechanism 11 through the cooperation of two jackscrews, so that the height of the magazine cavity 22 (mentioned below) can be adjusted. The cartridge cavity 22 is ensured to be matched with the plate roller 200 more appropriately, and excessive misalignment between the opening 202 of the cartridge cavity 22 and the plate roller 200 due to height problems is prevented, so that excessive overflow of slurry is avoided and waste is avoided. The use of the jackscrew can refer to the use of the jackscrew in the general technology, and is not described herein again.

Please refer to the view angle of fig. 1, it should be noted that only the view angle is indicated here for providing a position reference. Alternatively, a long hole (no reference numeral because it is different from the position of the long hole 112 in the present embodiment) may be provided at the top of the fixing mechanism 11 in the view of fig. 1, and the tip of the mounting adjustment block 211 extends downward in the vertical direction to form a mounting portion, so that the side profile of the mounting bracket 21 whose side profile is L-shaped becomes U-shaped. The mounting portion is directly provided in the elongated hole, and the height position of the entire mounting bracket 21 with respect to the fixing mechanism 11 can be adjusted by controlling the depth of insertion of the mounting portion into the elongated hole. Further, the mounting portion can also slide along the length of the elongated hole, so that the entire mounting bracket 21 can slide relative to the elongated hole, enabling movement of the entire blade cartridge mechanism 20.

In detail, a long hole may be formed at the top of the fixing mechanism 11 in the view of fig. 1, a sliding groove may be formed at the back of the fixing mechanism 11, and then a plurality of adjusting holes may be formed at intervals in the vertical direction of the mounting portion. The mounting adjusting block 211 is inserted into the long hole, then a bolt is inserted into the sliding groove on the back side and penetrates through the adjusting hole, and then the mounting adjusting block 211 can be positioned by matching a nut. When the horizontal position of the scraper box mechanism 20 needs to be changed, the nut is loosened, and the whole scraper box mechanism 20 is directly moved along the long hole. When the height needs to be adjusted, the bolt and the nut are loosened, and the bolt is inserted into the adjusting hole with the required height.

In order to adjust the height more accurately, the height of the left side or the height of the right side of the fixing mechanism 11 can be further adjusted by using a parallelism adjusting mechanism 12.

It should be noted that the above-mentioned adjusting manner is only a simple example, and a person skilled in the art may set other types of horizontal position and height adjusting structures according to requirements, so that the doctor blade cartridge mechanism 20 and another doctor blade cartridge mechanism 20 can be adjusted to a reasonable position, which can meet the coating requirement, and does not cause the width of the blank area to be unsatisfactory.

Of course, whether horizontal adjustment or height adjustment is performed, the blade cartridge mechanism 20 needs to be fixed after being moved in place, so that the influence on the product quality caused by movement in the coating process is avoided.

In detail, the frame 10 includes a parallelism adjusting mechanism 12, the parallelism adjusting mechanism 12 is connected to the fixing mechanism 11, and the parallelism adjusting mechanism 12 is used for adjusting the height and the horizontal position of the fixing mechanism 11. The parallelism adjusting mechanism 12 can drive the scraper box mechanism 20 by changing the positions of the fixing mechanism 11 in the vertical direction and the horizontal direction, so that the parallelism and the matching degree of the scraper box mechanism 20 and the plate roller 200 can be more accurate. The parallelism adjusting mechanism 12 can refer to a mechanism generally used for adjusting the parallelism of the blade cartridge and the roller, and will not be described in detail here.

Referring to fig. 2 and 3, in the embodiment, the scraper box mechanism 20 includes an installation frame 21, a material box cavity 22, an end surface blocking block 23, and a scraper mechanism 24, the installation frame 21 is connected to the frame 10, the material box cavity 22 is disposed on the installation frame 21, the scraper mechanism 24 is disposed on two opposite sides of the opening 202 of the material box cavity 22, and the end surface blocking block 23 is disposed on the material box cavity 22 and can prevent slurry from overflowing from the edge of the opening 202.

As shown in fig. 2, the scraper mechanism 24 includes a scraper 241 (the scraper 241 is not shown in fig. 3) and a scraper platen 242, and the scraper 241 is connected to the cartridge cavity 22 through the scraper platen 242. The scraper pressing plate 242 can play a role in fixing the scraper 241, so that the scraper 241 can normally work, the scraper 241 can be fixed according to a proper angle, the matching angle between the scraper 241 and the plate roller 200 is more reasonable, and the scraping force is reduced. Alternatively, the scraper pressure plate 242 is rotatably connected to the cartridge cavity 22. Due to the fact that the scraper pressing plate 242 is rotationally connected with the material box cavity 22, the angle of the scraper 241 can be changed by rotating the scraper pressing plate 242 according to the diameter of the plate roller 200, a proper matching position between the scraper 241 and the plate roller 200 can be maintained, and severe scraping cannot occur mutually, so that the service life of the scraper 241 is prolonged, and meanwhile the service life of the plate roller 200 can be prolonged to a certain extent. In addition, the cooperation of the material box cavity 22 and the end face blocking block 23 can prevent slurry from overflowing from two sides of the position where the scraper box mechanism 20 is located, and ensure that the scraper mechanism 24 can be normally matched with the printing roller 200 to complete coating, and ensure that no slurry is contaminated in the blank area of the coated isolating membrane.

It is noted that the blade platen 242 and the cartridge cavity 22 are rotationally connected, but when the position of the blade 241 is adjusted in place, the blade platen 242 needs to be kept positionally stable relative to the cartridge cavity 22 to avoid the position of the blade 241 shifting to affect the coating.

Certainly, it can be considered that a torsion spring is arranged on the rotating shaft of the scraper pressing plate 242, so that the scraper pressing plate 242 has a tendency of twisting to the plate roller 200, and when the scraper 241 is matched with the plate roller 200, the twisting tendency of the scraper pressing plate 242 enables the scraper 241 to swing along with the rotation of the plate roller 200 on the basis of extruding the diaphragm, so as to reduce the scraping force on the plate roller 200 and the diaphragm, and avoid the rigid contact from causing large abrasion to the diaphragm or the plate roller 200.

In detail, in the present embodiment, a teflon layer is disposed on the inner wall of the cartridge cavity 22. The Teflon layer can improve the smoothness of the inner wall, so that the slurry can flow smoothly. This is advantageous for scraping a uniform layer of coating on the membrane. The box cavity 22 is provided with a feed port 221 and a feed back port 222, and the feed back port 222 is positioned above the feed port 221.

Based on the multi-chamber cartridge mechanism 100 described above, embodiments of the present application provide a gravure coating system that includes a feeding system, a plate roller 200, and the multi-chamber cartridge mechanism 100. The feeding system is used for feeding the blade cartridge mechanism 20, the printing roller 200 is disposed near the blade cartridge mechanism 20, and the blade edge of the blade 241 of the blade cartridge mechanism 20 abuts against the roller surface of the printing roller 200.

Specifically, the gravure coating system can be provided with no scraper box mechanism 20 in the region which is not required to be coated by using the multi-cavity material box mechanism 100, so that the scraper 241 of the scraper box mechanism 20 is not rubbed with the plate roller 200 in the blank region, the service life of the plate roller 200 is prolonged, the use amount of the scraper 241 is reduced, the risk of slurry leakage in the region which is not provided with the scraper box mechanism 20 is avoided, and the product quality is guaranteed.

Wherein, the plate roller 200 can also be designed into an anilox roller with different patterns on different parts. For example, the pattern associated with each blade cartridge mechanism 20 may be different to meet different coating requirements. It is to be understood that this is by way of example only and should not be construed as a limitation that the pattern must be different.

Referring to fig. 5, taking the multi-cavity magazine mechanism 100 of the two doctor blade magazine mechanisms 20 as an example, the feeding process of the feeding system is as follows:

the feed system includes a feed pump 310 and a slurry tank 320, the feed pump 310 drawing slurry tank 320 and delivering it through a feed conduit to feed port 221 and into cartridge cavity 22.

When the slurry in the cartridge cavity 22 reaches the return port 222, the slurry overflows from the return port 222, and merges through a hose-like conduit into the slurry tank 320.

The principle of the embodiment is as follows:

taking the case of two scraper box mechanisms 20 as an example, the scraper box mechanism 20 has a smaller width than the cartridges in the general technology, which allows the scraper box mechanisms 20 to be arranged only for the positions to be coated under the condition that the size of the diaphragm is not changed, and for the blank areas not to be coated, the unnecessary cartridge structures are directly omitted, so that the possibility that the areas to be left white are contaminated by the slurry in the cartridges is directly eliminated.

And because the printing roller 200 corresponding to the blank area does not need to contact the scraper 241, the service life can be longer, and meanwhile, the unnecessary consumption of the scraper 241 is saved. In addition, as the blank area is not contaminated by the slurry, the friction resistance between the diaphragm and the plate roller 200 is smaller, and the diaphragm is prevented from being stretched due to the fact that the contact angle between the diaphragm and the plate roller 200 is increased due to the resistance.

When the position of the area to be blank is different, such as when changing from edge painting to zebra painting, the width of the blank area can be changed by changing the position of the blade cartridge mechanism 20 along the elongated hole and adjusting the pitch of the adjacent blade cartridge mechanisms 20. Of course, in the case of zebra coating, a different number of blade cartridge mechanisms 20 should be provided depending on the specific coating requirements, and it should not be understood that only two blade cartridge mechanisms 20 as referred to in the above examples must be used restrictively.

In addition, when the device is matched with the plate roller 200, the position of the scraper box mechanism 20 relative to the plate roller 200 should be adjusted by installing the adjusting block 211 and the parallelism adjusting mechanism 12, so that the parallelism and the matching degree of the material box cavity 22 and the plate roller 200 are more accurate, and the risk of stretching the diaphragm in the conveying process due to the fact that the contact angle is increased because the resistance between the diaphragm and the plate roller 200 is increased due to insufficient alignment is avoided. The method is favorable for ensuring the quality of products, and avoids waste and equipment fouling caused by leakage of the slurry in the vertical direction.

To sum up, multi-chamber magazine mechanism 100 of this application is through setting up two and above scraper box mechanism 20 on frame 10, can directly remove the magazine structure of the position that need of diaphragm left blank from, has effectively solved the problem of thick liquids seepage to blank region, after combining version roller 200, feed system to form gravure coating system, can reduce the wearing and tearing of version roller 200 and scraper box mechanism 20 self scraper 241, improves life, and makes the product quality of the diaphragm after the coating secure.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
