Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a lithium battery pole piece rolling mill bearing seat with a heat dissipation device. Background Art

[0002] Roller press, also known as roller press, rolling mill, tablet press, is widely used in chemical, electronic and other industries. It has the advantages of adjustable, high hardness, high precision, automation, easy operation, etc. The pole pieces of lithium batteries need to be produced using rolling mills.

[0003] The existing document with announcement number CN217289812U discloses a Y-type rolling mill for rolling lithium battery pole pieces, including a frame, a support roller assembly arranged on the frame, and a driving device, wherein the support roller assembly includes an upper support roller and a lower support roller slidably connected to the frame through a lifting device, and an upper working roller and a lower working roller for rolling pole pieces are rotatably connected between the upper support roller and the lower support roller, and the upper working roller and the lower working roller are slidably connected to the frame through a working roller bearing seat, and a sliding track for easy disassembly and assembly is fixed on the frame along the axis direction of the upper working roller, and a roller that can move along the sliding track is provided on the working roller bearing seat, and also includes a limit device for limiting the position of the upper working roller and the lower working roller relative to the frame.

[0004] However, it is well known that the rolling mill rolls the pole piece raw material through the working rollers to make the pole piece into the required thickness. In this process, the bearings in the bearing seat support the working rollers. As the working rollers rotate, the bearings generate heat due to friction. Long-term continuous operation can easily cause the bearings to maintain high temperatures, which can reduce the life of the bearings. In addition, due to the thermal expansion of the bearings, the tightness of the connection between the working rollers and the bearings decreases, which leads to loose fit between the working rollers and the bearings, which can easily accelerate the wear of the bearings. In addition, due to the wear of the bearings, the accuracy of the working rollers decreases, which in turn leads to unstable quality of the pole pieces produced and a decrease in yield.

Similarly, a smooth transition treatment can be adopted between the cooling groove 5 and the liquid outlet 7. A refrigeration mechanism 4 is installed at the bottom of the support plate 1. The refrigeration mechanism 4 is connected with the liquid inlet hole 6 and the liquid outlet hole 7. The refrigeration mechanism 4 inputs low-temperature coolant into the cooling groove 5 through the liquid inlet hole 6, and then the low-temperature coolant dissipates heat and cools the outer ring of the bearing, thereby reducing the bearing temperature. The temperature of the coolant increases and flows back to the refrigeration mechanism 4 through the liquid outlet 7.

[0031] By providing a support plate 1, a mounting hole 2, a connecting plate 3, a cooling groove 5, a liquid inlet hole 6 and a liquid outlet hole 7, a refrigeration mechanism 4 is used to continuously circulate and inject coolant into the cooling groove 5, so as to dissipate heat and cool the rolling mill bearing installed in the mounting hole 2, so that the bearing is kept in a lower temperature range for use, which is beneficial to prolonging the service life of the bearing and avoiding other problems caused by increased bearing temperature.

[0038] Embodiment 4:

[0039] like Figure 4 As shown, a guide plate 14 is installed in the water tank 8. When in use, after the second connecting pipe 12 enters the water tank 8, the high-temperature coolant flows along the direction of the guide plate 14 to the bottom of the water tank 8, so that the high-temperature coolant can directly contact the bottom of the water tank 8 with a lower temperature, which is beneficial to cooling the coolant and preventing the high-temperature coolant from being directly pumped back into the water pump 11 without being cooled.

[0040] By installing the guide plate 14 in the water tank 8, the flow of the liquid in the water tank 8 can be guided to prevent the high-temperature coolant from being directly pumped back into the water pump 11 without being cooled.

[0049] By installing a filter 18 on one side of the heat dissipation fan 17 , the air entering the heat dissipation fan 17 can be filtered.

[0050] Working principle: When in use, the refrigeration mechanism 4 inputs low-temperature coolant into the cooling tank 5 through the liquid inlet hole 6, and then the low-temperature coolant dissipates heat and cools down the outer ring of the bearing, thereby reducing the temperature of the bearing. The coolant is heated up through heat exchange, and then flows back to the refrigeration mechanism 4 through the liquid outlet 7. The refrigeration mechanism 4 cools down the high-temperature coolant, and then sends it into the cooling tank 5. This cycle is repeated, thereby continuously cooling the bearing, so that the bearings of the rolling mill can be kept in a lower temperature range during long-term operation, which is beneficial to increasing the service life of the bearings and avoiding other problems caused by increased bearing temperature.
