Problems solved by technology

[0002] See attached figure 1 , 2 , the current heat conduction oil heating roller is a single-inlet and single-outlet circulating oil circuit, the temperature of the oil inlet end is slightly higher than that of the oil outlet end relative to the width of the roll surface, so there will be a relatively large convexity between the roll surfaces B and C, Moreover, A and D, and B and C are not equal, which adversely affects the straightness of the roll surface and cannot meet the high-precision requirements of the battery pole piece rolling process; The temperature at both ends will be relatively low, the thermal expansion will be small, and the roll surface slump width A and D sections will be wider, thus reducing the effective use width of the roll surface

Embodiment Construction

[0016] See attached figure 1 , 2 , the existing heat conduction oil heating roller is a single-inlet and single-outlet circulating oil circuit, and the temperature of the oil inlet end is slightly higher than that of the oil outlet end relative to the width of the roll surface, so there will be a relatively large convexity between the roll surfaces B and C , and A and D, B and C are not equal, which will have a negative impact on the straightness of the roll surface and cannot meet the high-precision requirements of the battery pole piece rolling process; in addition, due to the relatively large heat dissipation area on both ends of the roll shaft, the The temperature at both ends of the surface will be relatively low, the thermal expansion will be small, and the roll surface sag width A and D sections will be wider, thereby reducing the effective use width of the roll surface.

[0017] See attached image 3 , the structure of a specific embodiment of the present invention i...

Abstract

The invention discloses a heat-conducting oil heating roller. The structure of the roller comprises a roll shaft and a shaft sleeve, wherein the shaft sleeve is sleeved on the outer circumference of the roll shaft, an oil path formed by spiral grooves is formed on the outer circumference of the roll shaft, the oil inlet and the oil outlet of the oil path are arranged on the two end faces of the roll shaft respectively, and the oil path is an opposite double oil path formed by the spiral grooves arranged in an intercrossed manner; meanwhile, an annual oil path is formed at each of the two internal ends of the roll shaft. The heating roller is used in the rolling process of battery pole pieces, and can ensure the uniformity of the thermal deformation of the roll face of the roll shaft, keepthe high linearity of the roll face, improve the rolling quality of the battery pole pieces and can increase the effective use width of the roll face of the roll shaft.

Description

technical field [0001] The invention relates to a heat-conducting oil heating roller, in particular to a heat-conducting oil heating roller used for rolling battery pole pieces. Background technique [0002] See attached figure 1 , 2 , the current heat conduction oil heating roller is a single-inlet and single-outlet circulating oil circuit, the temperature of the oil inlet end is slightly higher than that of the oil outlet end relative to the width of the roll surface, so there will be a relatively large convexity between the roll surfaces B and C, Moreover, A and D, and B and C are not equal, which adversely affects the straightness of the roll surface and cannot meet the high-precision requirements of the battery pole piece rolling process; The temperature at both ends will be relatively low, the thermal expansion will be small, and the roll surface sag width A and D sections will be wider, thereby reducing the effective use width of the roll surface.
