Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing devices, and particularly relates to an ink delivery roller structure for a coater. Background Art

[0002] In the existing coating technology, there is a phenomenon of material splashing. If a semi-sealed material box is used to block the splashing of the slurry, it will not only cause difficulties in manufacturing and assembly, but also cause great trouble in cleaning and disassembly, increasing the labor cost.

Although the phenomenon of material splashing is not serious, the position of the coating roller with a small roller diameter is fixed, and the dipping amount of the coating roller with a small roller diameter immersed in the slurry is uncontrollable, which leads to uncontrollable slurry amount transferred to the plate roller, poor flexibility, and greatly limits the coating speed.

[0049] Refer to Figures 1 to 7 , an ink delivery roller structure for a coating machine, comprising: a left mounting plate 11, a right mounting plate 12, an ink delivery roller 2, a left roller arm 31, a left ink delivery roller adjusting mechanism 41, a right roller arm 32 and a right ink delivery roller adjusting mechanism 42;

[0050] The ink delivery roller 2 is arranged between the left mounting plate 11 and the right mounting plate 12.

[0052] One end of the left ink delivery roller adjusting mechanism 41 is hinged to the left mounting plate 11, and the other end of the left ink delivery roller adjusting mechanism 41 is hinged to the left roller arm 31; one end of the right ink delivery roller adjusting mechanism 42 is hinged to the right mounting plate 12, and the other end of the right ink delivery roller adjusting mechanism 42 is hinged to the right roller arm 32;

[0053] The left ink delivery roller adjusting mechanism 41 can extend or retract to drive the left roller arm 31 to rotate relative to the left mounting plate 11; the right ink delivery roller adjusting mechanism 42 can extend or retract to drive the right roller arm 32 to rotate relative to the right mounting plate 12; thereby adjusting the relative position between the ink delivery roller 2 and the cartridge 5.

[0054] Through the cooperation of the left ink delivery roller adjusting mechanism 41 and the right ink delivery roller adjusting mechanism 42, the dipping depth of the ink delivery roller 2 in the cartridge 5 is adjusted to control the dipping amount of the ink delivery roller 2, and the gap between the ink delivery roller 2 and the plate roller is adjusted, thereby controlling the amount of slurry transferred from the ink delivery roller 2 to the plate roller and avoiding slurry splashing during the coating process.

[0055] Refer to Figure 2 Further, the left roller arm 31 includes a left long roller arm 311 and a left short roller arm 312. One end of the left long roller arm 311 is connected to the ink delivery roller 2. The other end of the left long roller arm 311 is fixedly connected to the left short roller arm 312 and is hinged to the left mounting plate 11. The left ink delivery roller adjusting mechanism 41 is hinged to the left short roller arm 312;

[0056] Refer to Figure 1 The right roller arm 32 includes a right long roller arm 321 and a right short roller arm 322. One end of the right long roller arm 321 is connected to the ink delivery roller 2. The other end of the right long roller arm 321 is fixedly connected to the right short roller arm 322 and is hinged to the right mounting plate 12. The right ink delivery roller adjusting mechanism 42 is hinged to the right short roller arm 322.

[0057] Refer to Figures 1 to 2 Specifically, both the left ink delivery roller adjusting mechanism 41 and the right ink delivery roller adjusting mechanism 42 include a cylinder adjusting mechanism 411 and a lead screw adjusting mechanism 412;

[0058] One end of the cylinder adjusting mechanism 411 is hinged to the end of the left short roller arm 312 / right short roller arm 322 far from the left long roller arm 311 / right long roller arm 321, and the other end of the cylinder adjusting mechanism 411 is hinged to the left mounting plate 11 / right mounting plate 12;

[0059] One end of the lead screw adjusting mechanism 412 is hinged to the left short roller arm 312 / right short roller arm 322 and is located between the left long roller arm 311 / right long roller arm 321 and the cylinder adjusting mechanism 411, and the other end of the lead screw adjusting mechanism 412 is connected to the left mounting plate 11 / right mounting plate 12.

[0060] The cylinder adjusting mechanism 411 and the lead screw adjusting mechanism 412 cooperate to raise the inking roller 2 to different heights, adjust the gap between the inking roller 2 and the plate roller, and increase its applicability and variability.

[0061] Specifically, the fixed end of the cylinder adjusting mechanism 411 is hinged and provided on the left mounting plate 11, and the output end of the cylinder adjusting mechanism 411 is hinged to the right short roller arm 322;

[0062] Refer to Figure 3 As shown in the figure, the left inking roller adjusting mechanism 41 and the right inking roller adjusting mechanism 42 are the same. Taking the positional relationship between the left inking roller adjusting mechanism 41 and the left mounting plate 11 as an example: the lead screw adjusting mechanism 412 includes a slide rail 4121, a slider 4122, a lead screw 4123, a handwheel 4124, a fixing block 4125, and an adjusting arm 4126;

[0063] The fixing block 4125 is fixedly provided on the left mounting plate 11, the slider 4122 is slidably provided on the slide rail 4121, the lead screw 4123 sequentially passes through the fixing block 4125 and the slider 4122, the lead screw 4123 is rotatably connected to the fixing block 4125, the lead screw 4123 is in threaded cooperation with the slider 4122, and the handwheel 4124 is fixedly connected to the lead screw 4123 and is provided on the side of the fixing block 4125 facing away from the slider 4122;

[0064] One end of the adjusting arm 4126 is provided with a long slot 4126-1 and a limiting block 4126-2, and a sliding column 4122-1 on the slider 4122;

[0065] The long slot 4126-1 at one end of the adjusting arm 4126 is slidably matched with the sliding column 4122-1, and the other end of the adjusting arm 4126 is hinged to the left short roller arm 312;

[0066] When the inking roller 2 needs to be adjusted, when the cylinder adjusting mechanism 411 drives the left short roller arm 312 to move, since the adjusting arm 4126 is hinged to the left short roller arm 312, the sliding column 4122-1 will be driven to slide in the long slot 4126-1;

[0067] Rotating the handwheel 4124 drives the screw rod 4123 to rotate. Since the internal thread of the slider 4122 is engaged with the external thread of the screw rod 4123, the slider 4122 moves along the axial direction of the screw rod 4123 until the sliding column 4122-1 abuts against the limit block 4126-2; continue to rotate the handwheel 4124 so that the adjusting arm 4126 pushes the left short roller arm 312, thereby pushing the material delivery roller 2, and adjusting the immersion depth of the ink delivery roller 2 in the material box 5.

[0068] Most of the existing ink delivery rollers 2 deliver ink passively, driven by the friction force when the plate roller rotates. This type of ink delivery roller needs to be in close contact with the plate roller all the time. Due to the long-term friction between the ink delivery roller and the plate roller, the surface of the ink delivery roller is easily worn, affecting the coating effect; secondly, due to the wide variety of slurries, for slurries with good fluidity and viscosity, the ink delivery roller can stably and evenly deliver the slurry to the surface of the plate roller, but relying solely on the friction force between the ink delivery roller and the plate roller is not enough to ensure that the ink delivery roller can maintain stable rotation in an environment with poor slurry fluidity, which will make the slurry delivered to the surface of the plate roller not uniform.

[0069] Reference Figure 4 Therefore, in order to solve the above technical problems, preferably, the left mounting plate 11 is provided with a driving member 6, and one side of the left mounting plate 11 is provided with a transmission mechanism 7 which is transmission-connected to the ink delivery roller 2; the transmission mechanism 7 is connected to the output end of the driving member 6, and the rotation of the driving member 6 can drive the ink delivery roller 2 to roll through the transmission mechanism 7.

[0070] The arrangement of the driving member 6 and the transmission mechanism 7 can provide the power for the active rotation of the ink transfer roller 2. In this way, the power for the rotation of the ink transfer roller 2 includes not only the friction of the plate roller but also the torque provided by the driving member 6, which can reduce the friction on the surface of the ink transfer roller 2 and stabilize the rotation, thereby achieving uniform transfer of the slurry.

[0071] Reference Figures 4 to 6 , more specifically, the transmission mechanism 7 includes a driving gear 71, a bearing gear 72, a transmission gear 73 and a roller gear 74;

[0072] The driving gear 71 is arranged on the output end of the driving member 6;

[0073] A roller arm rotating bearing 313 is provided at the connection position between the left short roller arm 312 and the left long roller arm 311, and the left short roller arm 312 and the left long roller arm 311 are fixedly connected to the outer ring of the roller arm rotating bearing 313; a left roller arm supporting shaft 111 fixedly connected to the inner ring of the roller arm rotating bearing 313 is provided on the left mounting plate 11, and the left roller arm 31 rotates relative to the left mounting plate 11 with the left roller arm supporting shaft 111 as the rotation center;

[0074] The bearing gear 72 is provided on the left roller arm support shaft 111, and the axis of the bearing gear 72 is coaxial with the axis of the left roller arm support shaft 111; a gear bearing 721 is provided on the bearing gear 72, and the inner ring of the gear bearing 721 is fixedly connected to the left roller arm support shaft 111;

[0075] There are several driving gears 73, which are provided between the bearing gear 72 and the roller gear 74;

[0076] The roller gear 74 is fixedly connected to the left end of the ink delivery roller 2;

[0077] The driving gear 71 meshes and drives with the bearing gear 72, the bearing gear 72 meshes and drives with the driving gear 73, and the driving gear 73 meshes and drives with the roller gear 74.

[0078] Refer to Figure 4 、 Figure 6 , more specifically, a limiting member 21 is fixedly connected to the left end of the ink delivery roller 2, and a protruding flange 211 is provided on the limiting member 21; the setting of the flange 211 can prevent the slurry from flowing into the left roller arm 31 and corroding the internal parts.

[0079] Refer to Figure 7 , the left roller arm 31 includes an ink delivery roller mounting seat 314 and a rotating arm 315; the ink delivery roller mounting seat 314 is arc-shaped and is provided at one end close to the ink delivery roller 2; the rotating arm 315 is arc-shaped and is hinged to the ink delivery roller mounting seat 314, and a fixing member 316 for fixing the free end of the rotating arm 315 is further provided on the ink delivery roller mounting seat 314. When the fixing member 316 fixes the free end of the rotating arm 315 to the ink delivery roller mounting seat 314, the rotating arm 315 and the ink delivery roller mounting seat 314 enclose to fix the limiting member 21. At this time, as Figure 3 shown, the flange 211 fits with the outer surface of the left roller arm 31.

[0080] When the ink delivery roller 2 needs to be replaced, the fixing member 316 is removed, and the rotating arm 315 is rotated to a Figure 7 state, and the ink delivery roller 2 can be removed from the left roller arm 31; the right roller arm 31 can also have the above-mentioned removal structure to facilitate the removal of the ink delivery roller 2 from the right roller arm 31;

[0081] Refer to Figure 7 , more specifically, the left roller arm 31 further includes a cover plate 317;

[0082] The cover plate 317 is provided on the ink delivery roller mounting seat 314 and on one side of the rotating arm 315, and the cover plate 317 is detachably connected to the ink delivery roller mounting seat 314 and the rotating arm 315;

[0083] The cover plate 317, the ink delivery roller mounting seat 314 and the rotating arm 315 enclose a cavity for installing the roller gear 74.

[0084] Further, open grooves 51 are provided on both side walls of the ink cartridge 5, and the ink delivery roller 2 is arranged in the open grooves 51;

[0085] Axial head retaining rings 23 are provided at both ends of the ink delivery roller 2 and inside the ink cartridge 5.

[0086] When this structure is in use, the diameter of the coated plate roller is much larger than that of the ink delivery roller 2. Therefore, the rotational speed of the ink delivery roller 2 has to be much higher than that of the plate roller to provide sufficient slurry for the plate roller. If the depth of the ink delivery roller 2 immersed in the slurry of the ink cartridge 5 is too deep, the slurry will flow out of the ink cartridge 5 along the axial heads at both ends of the ink delivery roller 2; arranging the axial head retaining rings 23 can, on the one hand, prevent the slurry from flowing along the ink delivery roller into the left roller arm 31 and the right roller arm 32 on both sides, avoiding the corrosion of the components inside the left roller arm 31 and the right roller arm 32 by the slurry; on the other hand, when the slurry flows to the axial head retaining rings 23, the slurry can accumulate at the lowest point of the axial head retaining rings 23, and finally the accumulated slurry drips into the ink cartridge 5 under the action of gravity, realizing the recycling of the slurry.

[0087] Specifically, a driving gear guard 112 is sleeved outside the driving gear 71, and the driving gear guard 112 is communicated with the left roller arm 31.

[0088] Further, the outer layer of the ink delivery roller 2 can be made of anti-corrosion rubber. Specifically, the anti-corrosion rubber is ethylene propylene diene monomer (EPDM) black rubber coating, which is corrosion-resistant, friction-resistant and anti-static, slowing down the corrosion rate of the slurry on the roller. And the surface of the ink delivery roller 2 is flat and the adhesion of the EPDM black rubber coating is strong, and it will not adhere to excess slurry, enabling high-speed material delivery, thereby effectively reducing the phenomenon of flying materials and greatly broadening the applicable range of the slurry;

[0089] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
