Problems solved by technology

Due to the long distance between the preheating position and the rolling area of ​​the lithium battery pole piece, and the work roll itself is not preheated, the temperature of the lithium battery pole piece has dropped a lot during rolling, which affects the rolling effect and cannot guarantee the lithium battery. High quality of battery pole pieces
[0003] "Heat-conducting oil heating roll" (CN201684775U) patent technology discloses a technology of rolling in and out of heat-conducting oil at the shaft end on the same side. The temperature of the oil outlet is high, the processing and installation of the connecting parts are poor, and there is heat exchange between the oil passages at the same side of the oil inlet and outlet, which is not conducive to controlling the temperature of the rolling surface

Embodiment 1

[0021] A roll for rolling lithium battery pole pieces. The roll as figure 1 and figure 2 As shown, it includes a roll body 1 , a left annular oil passage sealing cover 4 , a right annular oil passage sealing cover 6 and a plug 10 .

[0022] Such as figure 1 As shown, the shape and structure of the roll body 1 is: the middle cylinder of the roll body 1 is the roll body, the left side of the roll body is the left oil passage cylinder, the left roll neck and the left shaft head, and the right side of the roll body is the Right oil passage cylinder, right roll neck and right spindle head.

[0023] Such as figure 1 and figure 2 As shown, the left center oil passage 2 and the right center oil passage 8 are processed on the left end of the left spindle head and the right end of the right spindle head along the center line; 5, the number of axial oil passages 5 is 30. The left oil channel cylinder close to the roller body is evenly opened with a left inclined oil channel 3, a...

Embodiment 2

[0029] A roll for rolling lithium battery pole pieces. Except following technical parameter, all the other are with embodiment 1:

[0030] The number of the axial oil passages 5 is 25-29 or 31-50; the number of the left inclined oil passages 3 is 5-9 or 11-12, and the inclination angle of the left inclined oil passages 3 is 8 ~15°; the number of radial oil holes 9 is 2~3; the location close to the surface of the roller body refers to the location where the radial distance from the surface of the roller body is 65~90mm.

[0031] The cross-section of the left annular oil passage sealing cover 4 and the right annular oil passage sealing cover 6 in this specific embodiment is L-shaped; A left annular oil passage is formed between the side surface and the surface of the left oil passage cylinder, and a right annular oil passage is formed between the right annular oil passage sealing cover 6 and the right side of the roll body and the surface of the right oil passage cylinder. The...

Abstract

The invention relates to a roller for rolling a pole piece of a lithium battery. According to the technical scheme, a left central oil duct (2) and a right central oil duct (8) are correspondingly machined in the left end of a left shaft head and the right end of a right shaft head along the central line, axial oil ducts (5) are evenly machined on the positions near the surface of a roller body, left inclined oil ducts (3) evenly formed in a left oil duct cylinder are communicated with the left central oil duct (2), right inclined oil ducts (7) are symmetrical with the left inclined oil ducts (3), and radial oil holes (9) are evenly formed in the right shaft head near a right roller neck. The left oil duct cylinder is provided with a left annular oil duct sealing cover (4), the left annular oil duct sealing cover (4) is fixed to the lateral surface of the roller body, a right annular oil duct sealing cover (6) is symmetrical with the left annular oil duct sealing cover (4), and a plug (10) is installed on the right end port of the right central oil duct (8). The roller for rolling the pole piece of the lithium battery is low in manufacturing process difficulty, and capable of guaranteeing uniform distribution of the temperature of the roller surface of the roller and improving the rolling quality of the pole piece of the lithium battery.

Description

technical field [0001] The invention belongs to the technical field of rolls. Specifically relates to a roll for rolling lithium battery pole pieces. Background technique [0002] When rolling lithium battery pole pieces, the temperature of the rolling surface of the roll needs to be kept at about 120°C to ensure the quality and yield of the finished product after rolling. The existing lithium battery pole piece heating device is heated by a heating box, and the heating box first preheats the lithium battery pole piece. Due to the long distance between the preheating position and the rolling area of ​​the lithium battery pole piece, and the work roll itself is not preheated, the temperature of the lithium battery pole piece has dropped a lot during rolling, which affects the rolling effect and cannot guarantee the lithium battery. High quality of battery pole pieces. [0003] "Heat-conducting oil heating roll" (CN201684775U) patent technology discloses a technology of rol...
