Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a manual winding reverse pressure roller assembly, a winding mechanism, and a primer coating machine. Background Technology

[0002] In the classification of coating machines, primer coating machines are used for substrate primer coating before the coating process. They uniformly coat the conductive paste onto the aluminum foil to achieve the appearance, size, and areal density within the design specifications. After drying, the foil is rolled up. While turret-type automatic winding machines improve automation and equipment utilization due to automatic cutting and tape connection, they inevitably cause bottom wrinkles during roll winding due to residual base tape after cutting. Furthermore, issues with the coating paste can lead to slippage and unwinding of the roll due to the low coefficient of friction on the substrate surface after oven drying. Other problems include horizontal lines caused by unstable tension, thermal expansion and contraction of the substrate and paste, and non-parallelism between rollers. Air bubbles introduced into the roll during winding can cause bulging. These abnormalities not only affect production efficiency and product quality but can also damage the coating machine and disrupt battery production processes, impacting battery yield and output.

[0003] To improve the yield of battery production, the fixed winding mechanism of the existing primer coating machine uses a pressure roller assembly to adjust the tension of the roll material. The pressure roller assembly is installed between the vertical plates and acts directly on the pressure roller through a cylinder. The pressure of the pressure roller acting on the roll material is controlled by controlling the air pressure of the pressure regulating valve.

[0004] However, the disadvantages of using existing pressure roller assemblies to adjust the coil tension are as follows: 1. When adjusting the cylinder air pressure, the output air pressure of the pressure regulating valve needs to be adjusted manually. However, the pressure regulating valve is usually located far from the pressure roller, requiring multiple people to adjust the pressure and observe during adjustment; 2. The cylinder output force is constant, requiring verification of a large pressure range, which results in greater wear on the substrate used for adjustment; 3. In adjustment experience, bottom wrinkles of the substrate mainly occur at the front winding of the substrate, requiring higher pressure at this time. However, the cylinder output force cannot be too large, otherwise the substrate will be easily crushed during subsequent winding; 4. The cylinder occupies a large space, requiring more space for layout and increasing additional costs. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a manual winding reverse pressure roller assembly, winding mechanism and primer coating machine. It uses manual adjustment in combination with counterweight blocks to reduce the cost of personnel adjustment. It has a simple structure, occupies little space, can adapt to the use requirements of different roll diameters, and reduces production costs and increases the yield of substrates.

[0006] On the one hand, the technical solution adopted by this utility model to solve its technical problem is:

[0007] A manual winding rewinding pressure roller assembly includes a pressure roller mounting base, a first optical shaft mounted on the pressure roller mounting base, a pressure roller bracket rotatably mounted on the first optical shaft, a counterweight assembly mounted at one end of the pressure roller bracket, and a pressure roller assembly mounted at the other end of the pressure roller bracket. When the pressure roller bracket rotates based on the first optical shaft, the pressure roller assembly can abut against the core. A locking member is provided between the first optical shaft and the pressure roller bracket to lock the rotation of the pressure roller bracket. The counterweight assembly includes a pressure roller counterweight shaft connected to the pressure roller bracket and several counterweight blocks detachably connected to the pressure roller counterweight shaft.

[0008] As a further improvement to the above technical solution, the pressure roller support includes a first pressure roller swing arm and a second pressure roller swing arm, and the first pressure roller swing arm and the second pressure roller swing arm are respectively fixedly connected to the first optical axis by a deep groove ball bearing.

[0009] As a further improvement to the above technical solution, the pressure roller counterweight shaft includes a first counterweight shaft and a second counterweight shaft, and a universal joint is connected between the first counterweight shaft and the second counterweight shaft.

[0010] As a further improvement to the above technical solution, the pressure roller assembly includes a roller guide shaft connected to the pressure roller bracket and a through-shaft roller rotatably connected to the roller guide shaft. A segmented rubber pressure roller adapter plate is respectively provided on the first pressure roller swing arm and the second pressure roller swing arm. A second optical shaft is rotatably connected between the two segmented rubber pressure roller adapter plates. Two adjusting roller shaft seats are fixedly connected to the second optical shaft. The roller guide shaft is connected between the two adjusting roller shaft seats.

[0011] As a further improvement to the above technical solution, a linear sliding platform is provided on each of the two adjusting roller bearings. The linear sliding platform is used to adjust the distance between the through roller and the second optical axis. The moving part of the linear sliding platform is connected to a universal bayonet, and the two ends of the through roller optical axis are respectively fixedly connected to the two universal bayonet.

[0012] As a further improvement to the above technical solution, the locking component includes a linear bearing mounting base fixedly connected to the first optical axis, a linear bearing fixedly connected to the linear bearing mounting base, and a limiting rod installed in the linear bearing. The first pressure roller swing arm is provided with a locking hole on the same axis as the limiting rod. When the limiting rod moves into the locking hole, it is used to lock the rotation of the first pressure roller swing arm on the first optical axis.

[0013] As a further improvement to the above technical solution, a limiting component is provided between the first optical axis and the second pressure roller swing arm, the limiting component being used to limit the rotation angle of the second pressure roller swing arm based on the first optical axis.

[0014] As a further improvement to the above technical solution, the limiting component includes a limiting bracket fixedly connected to the first optical axis, and a limiting bolt connected to the limiting bracket. The limiting bolt is located directly above the second pressure roller swing arm. When the second pressure roller swing arm rotates based on the first optical axis, the upper surface of the second pressure roller swing arm can abut against the bottom of the limiting bolt.

[0015] On the other hand, the present invention also provides a technical solution: a winding mechanism, including a vertical plate, a core, a guide roller, and a pressure roller assembly as described above, wherein the pressure roller mounting base is fixedly connected to the vertical plate.

[0016] On the other hand, the present invention also provides a technical solution: a primer coating machine, including the winding mechanism of the above-mentioned technical solution.

[0017] The beneficial effects of this utility model are:

[0018] By using manual adjustment combined with counterweights, the cost of personnel debugging is reduced. The pressure can be manually adjusted, and when high pressure is required for bottom winding, pressure can be applied manually. The winding effect can be directly observed, and the pressure can be increased or decreased to reduce the length affected by bottom wrinkles until the drum is stable and unwinds. The pressure can be changed by increasing or decreasing the number of counterweights until stable winding is achieved. This reduces the configuration of cylinders and air circuits, reducing the cost of use. After verifying the appropriate force, it can be converted to automatic cylinder control, reducing the initial investment cost and the debugging cost due to automation verification.

Detailed Implementation

[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / installations can use accessories such as screws and bolts, or can be directly connected by welding, bonding, etc. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Reference Figure 1This utility model provides a manual winding reverse pressure roller assembly 400, including a pressure roller mounting base 410, a first optical shaft 420, a pressure roller bracket, a counterweight assembly, and a pressure roller assembly. The two ends of the first optical shaft 420 are respectively fixedly mounted on one of the pressure roller mounting bases 410. The middle part of the pressure roller bracket is rotatably mounted on the first optical shaft 420. The two ends of the pressure roller bracket are respectively provided with a counterweight assembly and a pressure roller assembly. The pressure roller assembly includes a roller guide optical shaft 451 connected to the pressure roller bracket and a through-shaft roller 452 (made of through-shaft aluminum) rotatably connected to the roller guide optical shaft 451. When the pressure roller bracket rotates based on the first optical axis 420, the through roller 452 can abut against the wound core 310. In addition, a locking member is provided between the first optical axis 420 and the pressure roller bracket. The rotation of the pressure roller bracket can be locked by the locking member, so that the pressure roller bracket and the first optical axis 420 remain relatively fixed. The counterweight assembly includes a pressure roller counterweight shaft 441 connected to the pressure roller bracket and a plurality of counterweight blocks 442 detachably connected to the pressure roller counterweight shaft 441. The pressure of the through roller 452 abutting against the core 310 can be adjusted by the counterweight blocks 442.

[0029] Understandably, before the core 310 begins winding, the reverse pressure roller assembly 400 is manually pressed onto the core 310, and then the winding mechanism is started. Specifically, when the reverse pressure roller assembly 400 is working, the fixing between the pressure roller bracket and the first optical shaft 420 is first released by the locking device, allowing the pressure roller bracket to begin rotating up and down. The operator holds the handle on the pressure roller bracket and places the through roller 452 onto the core 310. Then, by adding or removing the counterweight 442, the pressure of the through roller 452 on the core 310 is controlled. This reduces the operation time of the reverse pressure roller assembly 400, reduces labor costs, and facilitates debugging.

[0030] In this embodiment, refer to Figure 1 The pressure roller support includes a first pressure roller swing arm 431 and a second pressure roller swing arm 432. The first pressure roller swing arm 431 and the second pressure roller swing arm 432 are respectively fixedly connected to the first optical shaft 420 by a deep groove ball bearing. With the above structure, the rotation angles of the first pressure roller swing arm 431 and the second pressure roller swing arm 432 can be different, thereby adapting to the parallelism between the core 310 and the through roller 452, reducing the difficulty of adjusting the parallelism between the reverse pressure roller assembly 400 and the coil.

[0031] It is understood that one end of the through roller 452 is connected to the through roller optical shaft 451 by a deep groove ball bearing, and the other end of the through roller 452 is connected to the through roller optical shaft 451 by a self-aligning ball bearing, so that the through roller 452 is set with one end fixed and the other end floating, so as to compensate for the relative position error of the first pressure roller swing arm 431 and the second pressure roller swing arm 432; in addition, the pressure roller counterweight shaft 441 includes a first counterweight shaft and a second counterweight shaft, and a universal joint 443 is connected between the first counterweight shaft and the second counterweight shaft. The universal joint 443 adapts to the positional deviation of the first pressure roller swing arm 431 and the second pressure roller swing arm 432, ensuring the adaptive adjustment of the parallelism between the through roller 452 and the core 310.

[0032] In this embodiment, refer to Figure 1 and Figure 2 The reverse pressure roller assembly 400 further includes two segmented rubber pressure roller adapter plates 453. The two segmented rubber pressure roller adapter plates 453 are respectively fixedly connected to the first pressure roller swing arm 431 and the second pressure roller swing arm 432. A second optical shaft 454 is rotatably connected between the two segmented rubber pressure roller adapter plates 453. Two adjusting roller shaft seats 455 are fixedly connected to the second optical shaft 454. The roller guide optical shaft 451 is connected between the two adjusting roller shaft seats 455, so that the roller guide optical shaft 451 can be manually driven to rotate the through roller 452 relative to the second optical shaft 454.

[0033] Furthermore, each of the two adjusting roller bearing seats 455 is provided with a linear sliding platform 456. The moving part of the linear sliding platform 456 is connected to a universal bayonet 457. The two ends of the roller guide shaft 451 are respectively fixedly connected to the two universal bayonet 457. The sliding direction of the linear sliding platform 456 is the line direction connecting the through roller 452 and the second optical axis 454. In this way, the distance between the through roller 452 and the second optical axis 454 can be adjusted by the linear sliding platform 456.

[0034] Understandably, the rotation of the second optical axis 454 drives the rotation of the through roller 452, the linear sliding platform 456 changes the forward and backward movement of the through roller 452, and the rotation of the pressure roller bracket as a whole can change the position of the through roller 452 pressing on the core 310, making it easier to find a suitable pressing point during debugging.

[0035] In this embodiment, refer to Figure 1 and Figure 3The locking mechanism includes a linear bearing mounting base 461, a linear bearing 462, and a limiting rod 463. The linear bearing mounting base 461 is fixedly connected to the first optical axis 420, and the linear bearing 462 is fixedly connected to the side of the linear bearing mounting base 461 away from the first optical axis 420. The limiting rod 463 passes through the linear bearing 462. In addition, the first pressure roller swing arm 431 is provided with a locking hole 464 on the same axis as the limiting rod 463. Thus, the limiting rod 463, which moves in the linear bearing 462, can slide into or out of the locking hole 464. When the limiting rod 463 slides into the locking hole 464, the first pressure roller swing arm 431 is fixed together with the first optical axis 420, thereby preventing the first pressure roller swing arm 431 from rotating on the first optical axis 420.

[0036] Furthermore, the linear bearing mounting base 461 is provided with a limit rod fastening block 465, and the limit rod fastening block 465 is provided with a sliding hole. The limit rod 463 is slidably connected in the sliding hole. The limit rod fastening block 465 is provided with a screw hole communicating with the sliding hole. A wing screw 466 is connected in the screw hole. By rotating the wing screw 466, the limit rod 463 can be pressed against it, thereby locking the moving position of the limit rod 463.

[0037] In this embodiment, refer to Figure 1 A limiting component is provided between the first optical axis 420 and the second pressure roller swing arm 432. The limiting component is used to limit the rotation angle of the second pressure roller swing arm 432 based on the first optical axis 420. Specifically, the limiting component includes a limiting bracket 471 fixedly connected to the first optical axis 420. A limiting bolt 472 is connected to the limiting bracket 471. The limiting bolt 472 is a polyurethane locking bolt. The limiting bolt 472 is located directly above the second pressure roller swing arm 432. When the second pressure roller swing arm 432 rotates based on the first optical axis 420, the upper surface of the second pressure roller swing arm 432 can abut against the bottom of the limiting bolt 472, thereby limiting the rotation of the second pressure roller swing arm 432 and the entire pressure roller bracket.

[0038] Another embodiment of this utility model provides a primer coating machine, including a winding mechanism. In a specific embodiment, see [reference needed]. Figure 4The winding mechanism includes a vertical plate 100, a core 310, a guide roller 200, and a reverse pressure roller assembly 400. The core 310 is mounted on the vertical plate 100 via a winding shaft chuck 300. The pressure roller mounting seat 410 is fixedly connected to the vertical plate 100. With the reverse pressure roller assembly 400, the guide roller 452 rotates from a low position to a high position. During the rotation of the guide roller 452, the pressure applied by the guide roller 452 to the core 310 also decreases. In this way, the pressure reduction process can be achieved without changing the counterweight 442, which is convenient and quick, and improves the working efficiency of the reverse pressure roller assembly 400 in the winding mechanism.

[0039] Furthermore, when the customer needs to turn the uncoated side of the 310 coated substrate core, the winding mechanism's feed mode needs to be changed. Figure 6 As shown (normal winding is as follows) Figure 5 As shown), at this time, the reverse pressure roller assembly 400 needs to be positioned at the lower part of the core 310. Its principle is the same as that of the reverse pressure roller assembly 400 positioned at the upper part of the core 310. It should be noted that the pressure pressed on the core 310 at this time is the equivalent pressure at the end of the pressure roller counterweight shaft 441 minus the equivalent pressure at the end of the through roller 452, which is the opposite of the calculation of the reverse pressure roller assembly 400 positioned at the upper part of the core 310.

[0040] During the debugging process, the parallelism between the roller 452 and the coil material was adjusted. Considering that the winding of the substrate starts from the empty core 310, the conventional method of adjusting the XY direction with screws to make the roller 452 parallel to the coil material takes up a lot of space. When the empty core 310 is in contact with the roller 452, the screws interfere with the core 310. Therefore, the deep groove ball bearings of the first pressure roller swing arm 431 and the second pressure roller swing arm 432 are used to achieve a small rotation, and the linear sliding platform 456 is used to move back and forth. When adjusting for parallelism, one side of the roller 452 is locked, and the position of the other side is adjusted by rotation and linear motion to achieve parallelism between the roller 452 and the coil material.

[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
