Description

Technical Field

[0001] This patent relates to the field of carbon-coated ink rollers, specifically a reverse ink roller device for carbon-coated aluminum foil in new energy batteries. Background Technology

[0002] In the production of carbonized aluminum foil, the reverse ink roller is responsible for transferring ink or coating from the ink tank and precisely controlling the supply to ensure that the carbonized layer thickness is uniform and consistent, so as to guarantee the quality of carbonized aluminum foil. The reverse ink roller usually adopts an anilox roller structure with many tiny holes on the surface. When the reverse ink roller rotates, the holes will immerse the ink or coating in the ink tank and carry it out.

[0003] However, after long-term use, the cells of the reverse ink roller will wear down, affecting ink transfer and coating effect. Since the cells are directly formed on the roller body, the entire roller body needs to be replaced when replacing it, resulting in unnecessary waste. Utility Model Content

Detailed Implementation

[0021] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of the structure of this patent. A reverse ink roller device for carbonized aluminum foil of new energy battery includes a connecting shaft 1 and a roller body 2. The roller body 2 is sleeved on the outside of the connecting shaft 1. The roller body 2 is annular and has a textured groove 3 on the outer side wall of the roller body 2.

[0023] This device is installed on an external carbon coating machine and rotated by an external drive motor. In the production of carbon-coated aluminum foil, ink or coating enters from the ink tank into the anilox groove 3 on the outside of the roller body 2, so that the supply can be precisely controlled to ensure that the carbon coating layer thickness is uniform and consistent, thereby ensuring the quality of aluminum foil carbon coating.

[0024] The roller body 2 is provided with multiple rollers. The outer side wall of the connecting shaft 1 is provided with a keyway 4, and the inner side wall of the roller body 2 is provided with a positioning groove 5. A connecting key 6 is inserted into the keyway 4 and can be inserted into the positioning groove 5.

[0025] This device divides its entire reverse ink roller into multiple roller bodies 2. The multiple roller bodies 2 are spliced ​​together to form a complete reverse ink roller. When the roller body 2 wears out after long-term use, only the damaged roller body 2 can be replaced, thereby reducing the maintenance cost of this device and avoiding waste.

[0026] The key 6 is designed to allow the roller 2 to rotate synchronously with the connecting shaft 1.

[0027] A fixing ring 7 is installed on the side wall of the connecting shaft 1. The roller body 2 can fit against the side wall of the fixing ring 7. A fixing rod 8 is inserted into the side wall of the fixing ring 7. A through hole 9 is opened on the side wall of the roller body 2. The fixing rod 8 can be inserted into the through hole 9.

[0028] By setting the fixing ring 7, the position of the edge roller 2 can be limited. Then, multiple rollers 2 are connected together by the fixing rod 8 and the rollers 2 are locked to avoid gaps between adjacent rollers 2 and to avoid affecting the carbon coating effect when the device is used.

[0029] Meanwhile, the fixing rod 8 can also make its multiple rollers 2 rotate synchronously.

[0030] The fixing rod 8 includes a rod body 81, a limiting block 82, and a locking nut 83. The rod body 81 is inserted into the through hole 9. The limiting block 82 is installed at one end of the rod body 81 and can fit against the side wall of the roller body 2. The other end of the rod body 81 is provided with an external thread. The locking nut 83 is installed on the outside of the rod body 81 by rotating the thread. The locking nut 83 can fit against the side wall of the fixing ring 7.

[0031] The rod 81 connects multiple rollers 2 together through the through hole 9, and then one end of the rod 81 passes through the side wall of the fixing ring 7 and locks the rollers 2 by tightening the locking nut 83.

[0032] An arc-shaped groove 10 is provided on one side wall of the roller body 2, and an arc-shaped protrusion 11 is installed on the other side wall of the roller body 2. The arc-shaped protrusion 11 can be inserted into the arc-shaped groove 10.

[0033] By setting the arc-shaped protrusion 11 and the arc-shaped groove 10, the stability of the connection between each roller body 2 can be improved, and the asynchronous rotation between each roller body 2 can be further prevented.

[0034] The connecting key 6 includes a key body 61, an elastic pad 62, and a wear-resistant rubber plate 63. The elastic pad 62 is attached to both the left and right side walls of the key body 61. The wear-resistant rubber plate 63 is attached to the outer side wall of the elastic pad 62. The wear-resistant rubber plate 63 can fit into the inner wall of the keyway 4 and the positioning groove 5.

[0035] By setting elastic pads 62 and wear-resistant rubber plates 63 on both sides of the key body 61, gaps can be avoided between the connecting key 6 and the keyway 4 and positioning groove 5, and the roller body 2 can be prevented from shaking after being installed on the connecting shaft 1.

[0036] An adapter sleeve 12 is installed at the end of the connecting shaft 1. The adapter sleeve 12 can be sleeved on the outside of the output end of the external drive motor. A hole 13 is opened on the side wall of the adapter sleeve 12. A pin 14 is inserted into the hole 13 and can penetrate the side wall of the output end of the external drive motor.

[0037] A rubber ring 15 is fitted to the side wall of the limiting block 82, and the rubber ring 15 can fit against the side wall of the roller body 2.

[0038] When this patent is working, the connecting shaft 1 and the roller body 2 are rotated by the drive of an external drive motor. In the production of carbonized aluminum foil, ink or coating enters from the ink tank into the anilox groove 3 on the outside of the roller body 2, so that the supply can be precisely controlled to ensure that the thickness of the carbonized layer is uniform and consistent, thereby ensuring the quality of the carbonized aluminum foil.

[0039] When the roller body 2 wears out after long-term use, the roller body 2 can be removed by loosening the locking nut 83 and using the rod 81. Then, only the worn roller body 2 needs to be replaced, and then it can be installed back on the connecting shaft 1.
