Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a dry film thinning device. Background Art

[0002] At present, a calendering device is generally used to calender electrode powder (electrode powder is a mixture of electrode active material, adhesive and conductive agent) to produce dry diaphragms. The dry diaphragms produced in this way are generally thicker, so they usually need to be thinned and their edges on both sides are trimmed to obtain a finished diaphragm of the required thickness and width. Due to the particularity of dry diaphragms, when the compression ratio is too large, the problem of diaphragm crystallization is prone to occur, so the diaphragm usually needs to be thinned multiple times. Existing dry diaphragm thinning devices generally include an unwinding mechanism for unwinding the dry diaphragm, a thinning mechanism for thinning the unwound dry diaphragm, and a winding mechanism for winding the thinned dry diaphragm. This thinning device can only thin the dry diaphragm once, and cannot trim the edges on both sides of the thinned dry diaphragm (i.e., the two sides in the length direction of the dry diaphragm), which cannot meet the use requirements.

Through the downward movement of the upper roller 23, downward pressure can be applied through the upper roller 23 to provide rolling pressure, and the pressure sensor can detect the downward pressure applied by the upper roller 23. In actual application, the upper roller 23 applies downward pressure, and the upper roller 23 and the lower roller 22 rotate in opposite directions, so that the dry film 100a located in the gap can be rolled, so that the first thinning process of the dry film 100a can be achieved.

The outer circumference of the cutter mounting shaft 4371 is rotatably sleeved with two circular cutter mounting seats 438 along the axis of the cutter mounting shaft 4371. In this embodiment, a cutter bearing is provided in the circular cutter mounting seat 438, and the cutter bearing is sleeved on the outer circumference of the cutter mounting shaft 4371 to provide support for the rotation of the circular cutter mounting seat 438. The two circular cutter mounting seats 438 are fixed to each other, and the circular cutter 439 is sandwiched between the two circular cutter mounting seats 438, and the circular cutter 439 partially protrudes from the outer circumferential surface of the two circular cutter mounting seats 438. The cutter driving member 436 is used to drive the cutter connecting plate 437 to move up and down, thereby driving the cutter mounting shaft 4371 to move up and down, and further driving the two circular cutter mounting seats 438 and the circular cutter 439 to move up and down, so that the circular cutter 439 can be pressed against the dry film 100a on the roller surface of the steel roller 41 or separated from the dry film 100a on the roller surface of the steel roller 41.

[0070] The two circular cutter mounting seats 438 are fixed to each other. Specifically, the two circular cutter mounting seats 438 have a first mounting hole and a second mounting hole, respectively. Cutter fasteners such as screws are installed in the first mounting hole and the second mounting hole, so that the two circular cutter mounting seats 438 are fixed together through the first mounting hole, the second mounting hole and the cutter fastener. The number of the first mounting hole and the second mounting hole can be set according to actual conditions.

[0071] The scraper module includes a scraper driving member 441, a scraper connecting plate 442, a scraper seat 443 and a scraper 445. The scraper driving member 441 is a cylinder, and the scraper driving member 441 is arranged on the inner side of the corresponding cutter mounting plate 435. The scraper connecting plate 442 is a T-shaped structure, and the scraper connecting plate 442 is arranged on the side of the scraper driving member 441 away from the corresponding cutter mounting plate 435, and the scraper connecting plate 442 partially protrudes from the top of the scraper driving member 441. The scraper seat 443 is arranged at the top of the scraper connecting plate 442, and the top of the scraper seat 443 is an inclined surface, which is inclined upward in the direction close to the corresponding cutter module, and the inclined surface is matched with an inclined block 444, and the inclined direction of the inclined block 444 is the same as the inclined direction of the inclined surface. In this embodiment, the inclined surface is provided with a first through hole, and the inclined block 444 is provided with a second through hole corresponding to the first through hole, and scraper fasteners such as screws are installed in the second through hole and the first through hole. A scraper 445 is sandwiched between the side of the tilting block 444 close to the corresponding cutter module and the inclined surface, and a portion of the scraper 445 protrudes from one end of the tilting block 444 close to the corresponding cutter module. The side of the scraper 445 away from the corresponding cutter mounting plate 435 (that is, the side of the scraper 445 close to the center of the roller surface of the steel roller 41) and the side of the circular cutter 439 away from the corresponding cutter mounting plate 435 (that is, the side of the circular cutter 439 close to the center of the roller surface of the steel roller 41) are located in the same vertical plane. The scraper driving member 441 is used to drive the scraper connecting plate 442 to move up and down, thereby driving the scraper seat 443 to move up and down, and further driving the tilting block 444 and the scraper 445 to move up and down, so that the end of the scraper 445 away from the tilting block 444 can be pressed against the corresponding cutting waste or separated from the corresponding cutting waste.

[0072] In actual application, by rotating the hand wheel 433, the screw rod 432 can be rotated. The rotation of the screw rod 432 can drive the two nuts 434 to move toward or away from each other, thereby driving the two cutter mounting plates 435 to move toward or away from each other, and then driving the two cutter modules and the two scraper modules to move toward or away from each other, so that the spacing between the circular cutters 439 of the two cutter modules and the spacing between the scrapers 445 of the two scraper modules can be adjusted, so that the trimming of dry film sheets 100a of different widths can be adapted, and the application range is wide. When the circular cutters 439 of the two cutter modules are respectively pressed against the dry film sheet 100a on the roller surface of the steel roller 41 and the steel roller 41 rotates, the circular cutters 439 of the two cutter modules can cut the edges of both sides of the dry film sheet 100a, so that the edges of both sides of the dry film sheet 100a can be trimmed, so that the dry film sheet 100a of the required width can be obtained. Two pieces of cutting waste formed after the circular cutters 439 of the two cutting knife modules respectively cut the two side edges of the dry film 100a will adhere to the roller surface of the steel roller 41. When the ends of the scrapers 445 of the two scraper modules away from the inclined block 444 are pressed against the two pieces of cutting waste and the steel roller 41 rotates, the two pieces of cutting waste can be scraped off the roller surface of the steel roller 41 through the ends of the scrapers 445 of the two scraper modules away from the inclined block 444.

[0073] Furthermore, two second through holes corresponding to the first through hole are provided at the bottom end of the cutter mounting plate 435, the first through hole is located between the two second through holes, and a cutter shaft sleeve 447 is provided through the second through hole. Two cutter connecting rods 446 are provided between the inner sides of the two cutter racks 431, the two cutter connecting rods 446 are arranged in parallel with the screw rod 432, the screw rod 432 is located between the two cutter connecting rods 446, and the cutter shaft sleeves 447 in the two second through holes are respectively sleeved on the outer circumferences of the two cutter connecting rods 446 and can move along the corresponding cutter connecting rods 446 respectively. A first C-shaped part 448 is sleeved on the outer periphery of one end of the cutter sleeve 447 away from the center of the corresponding cutter connecting rod 446. Two first C-shaped part mounting holes 4481 are respectively provided at both ends of the first C-shaped part 448. The first C-shaped part mounting holes 4481 extend to the outer periphery of the first C-shaped part 448. First bolts are installed in the two first C-shaped part mounting holes 4481. The first bolts abut against the outer periphery of the end of the cutter sleeve 447 away from the center of the corresponding cutter connecting rod 446. A second C-shaped member 449 is provided at one end of the first C-shaped member 448 away from the center of the corresponding cutter connecting rod 446. The second C-shaped member 449 is sleeved on the outer periphery of the corresponding cutter connecting rod 446. Two second C-shaped member mounting holes 4491 are respectively provided at both ends of the second C-shaped member 449. The second C-shaped member mounting holes 4491 extend to the outer periphery of the second C-shaped member 449. Second bolts are installed in the two second C-shaped member mounting holes 4491. The second bolts abut against the outer periphery of the corresponding cutter connecting rod 446. The two cutter connecting rods 446 can provide a guiding effect for the two cutter mounting plates 435 to move toward or away from each other. The first C-shaped member 448 and the second C-shaped member 449 can fix the cutter sleeve 447 on the corresponding cutter connecting rod 446 to prevent the cutter sleeve 447 from moving along the corresponding cutter connecting rod 446.

[0074] When it is necessary to reduce the spacing between the circular cutters 439 of the two cutting knife modules and the spacing between the scrapers 445 of the two scraper modules, the first bolt on the first C-shaped member 448 and the second bolt on the second C-shaped member 449 can be removed first, and then the hand wheel 433 can be rotated to drive the screw rod 432 to rotate, and then the two nuts 434 can be driven to move toward each other. The movement of the two nuts 434 towards each other can drive the two cutting knife mounting plates 435 to move towards each other. The movement of the two cutting knife mounting plates 435 towards each other can drive the two cutting knife modules and the two scraper modules to move towards each other, and can drive the corresponding cutting knife sleeves 447 to move along the corresponding cutting knife connecting rod 446. In this way, the spacing between the circular cutters 439 of the two cutting knife modules and the spacing between the scrapers 445 of the two scraper modules are reduced, and then the first bolt is installed in the two first C-shaped member mounting holes 4481 of the first C-shaped member 448 and the second bolt is installed in the two second C-shaped member mounting holes 4491 of the second C-shaped member 449. When it is necessary to increase the distance between the circular cutters 439 of the two cutter modules and the distance between the scrapers 445 of the two scraper modules, the adjustment steps are the same as the above steps, the only difference is that the rotation direction of the hand wheel 433 is opposite to the rotation direction of the above steps.

[0075] A waste box 451 is provided at the bottom end of the two cutting racks 431. After the two pieces of cutting waste are scraped off the roller surface of the steel roller 41 by the two scraper modules respectively, the two pieces of cutting waste can fall into the waste box 451, so that the cutting waste can be collected through the waste box 451.

In the process of winding up the trimmed dry film 100a by the winding shaft 52, since the diameter of the finished film roll 200 wound on the winding shaft 52 will become larger and larger, the winding shaft 52 is driven to move away from the trimming mechanism 40 by adjusting the driving member 55, so that the distance between the winding shaft 52 and the trimming mechanism 40 can be increased, which makes it easier for the winding shaft 52 to wind up the trimmed dry film 100a.

[0084] In this embodiment, combined with Fig.16 and Fig.17As shown, the trimming mechanism 40 also includes a cache assembly, which includes a cache connecting rod 491, a cache counterweight 492 and a cache roller. The cache connecting rod 491 is set through the connecting rod through hole at one end of the rubber roller rotating member 4711, and the rubber roller connecting rod 491 is inclined upward in a direction away from the steel roller 41. The end of the rubber roller connecting rod 491 close to the steel roller 41 is provided with a cache counterweight 492, and the cache counterweight 492 is located to the left between the roller surface of the rubber roller 47 and the roller surface of the steel roller 41. The cache roller is located above the rubber roller 47 and the reel shaft 52 of the reeling mechanism 50. The buffer roller includes a buffer roller shaft 4931 and a buffer roller 4932 rotatably mounted on the outer periphery of the buffer roller shaft 4931. One end of the buffer roller shaft 4931 is rotatably arranged in a through hole at one end of the rubber roller connecting rod 491 away from the steel roller 41. The other end of the buffer roller shaft 4931 faces the connecting frame 51. Two roller bearings are respectively arranged in both ends of the buffer roller 4932. The two roller bearings are respectively mounted on the outer periphery of the buffer roller shaft 4931 to provide support for the rotation of the buffer roller 4932. In actual application, after the two side edges of the dry film 100a are trimmed by the circular cutters 439 of the two cutting modules, the dry film 100a bypasses from below the roller surface of the rubber roller 47, above the buffer roller 4932, and below the winding shaft 52. Under the action of the gravity of the buffer counterweight 492, the buffer roller can be kept in a position above the winding shaft 52 and the rubber roller 47, as shown in FIG. Fig.16 and Fig.17 As shown, the tape path of the dry film 100a on the rubber roller 47, the buffer roller and the reel 52 is inverted V-shaped, so that the trimmed dry film 100a can be cached and the dry film 100a can be prevented from being broken.

[0085] Through the above structure, in actual application, the unwinding sleeve 101 of the dry film stock roll 100 is first mounted on the outer periphery of the unwinding shaft 12, and then the unwinding shaft 12 is driven to rotate by the unwinding driving member, so that the dry film 100a of the dry film stock roll 100 can be unwound, and the unwound dry film 100a can pass through the gap of the primary thinning mechanism 20, and the lower roller driving member and the upper roller driving member of the primary thinning mechanism 20 respectively drive the lower roller 22 and the upper roller 23 to rotate in opposite directions, and the two pressure driving members 28 of the primary thinning mechanism 30 drive the upper roller 23 to move downward to provide rolling pressure, so that the dry film 100a located in the gap can be rolled by the lower roller 22 and the upper roller 23 of the primary thinning mechanism 20, so that the first thinning treatment of the dry film 100a can be achieved. After the first thinning treatment, the dry film 100a passes through the bottom of the first buffer body 622, the top of the pressure roller body 642, and the bottom of the second buffer body 632 in turn, and then enters the gap of the secondary thinning mechanism 30, and the lower roller 22 and the upper roller 23 are driven to rotate in opposite directions by the lower roller driving member and the upper roller driving member of the secondary thinning mechanism 30 respectively, and the upper roller 23 is driven downward by the two pressure driving members 28 of the secondary thinning mechanism 30 to provide rolling pressure, so that the dry film 100a located in the gap can be rolled by the lower roller 22 and the upper roller 23 of the secondary thinning mechanism 30, so that the dry film 100a can be subjected to a second thinning treatment, so that the dry film 100a of the required thickness can be obtained. After the second thinning treatment, the dry film 100a passes under the roller surface of the steel roller 41 of the trimming mechanism 40, and the rubber roller driving assembly drives the rubber roller 47 to rotate, so that the rubber roller 47 can drive the steel roller 41 to rotate synchronously, and at the same time, the cutter driving parts 436 of the two cutter modules respectively drive the corresponding circular cutters 439 to move upward, so that the two circular cutters 439 can be pressed against the dry film 100a on the roller surface of the steel roller 41, so that the circular cutters 439 of the two cutter modules can cut the edges of both sides of the dry film 100a, so that the dry film after the second thinning treatment can be trimmed. The two side edges of the sheet 100a are trimmed, so that the dry film 100a of the required width can be obtained, and the cutting waste cut by the circular cutters 439 of the two cutting knife modules will adhere to the roller surface of the steel roller 41. At this time, the scraper driving parts 441 of the two scraper modules respectively drive the corresponding scrapers 445 to move upward, so that the ends of the scrapers 445 of the two scraper modules away from the inclined block 444 can be pressed against the two pieces of cutting waste respectively, so that the scrapers 445 of the two scraper modules can scrape off the two pieces of cutting waste adhering to the roller surface of the steel roller 41, and the scraped waste can fall into the waste box 451.The trimmed dry film 100a is passed around the bottom of the rubber roller 47, passed over the top of the buffer roller 4932 of the buffer roller, and then rolled up on the winding reel 102 on the outer periphery of the winding shaft 52, so that a finished film roll 200 can be obtained.

[0086] The utility model can realize multiple thinning treatments on the unwound dry film 100a by setting up multiple thinning mechanisms, so as to obtain the dry film 100a of the required thickness. The side edges of the dry film 100a that has undergone the last thinning treatment can be trimmed by the trimming mechanism 40, so as to obtain the dry film 100a of the required width. Compared with the prior art, the utility model can realize multiple thinning treatments on the dry film 100a, and can trim the side edges of the dry film 100a that has undergone multiple thinning treatments, which greatly meets the use requirements.

[0087] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
