Problems solved by technology

Since the temperature of the rolling surface of the working roll is room temperature, the hot rolling effect of the lithium battery pole piece is very poor during rolling, and the high quality of the lithium battery pole piece cannot be guaranteed.
[0003] "A kind of oil heating roll" (CN201684775U) patent technology, heat conduction oil is passed inside the roll to keep the temperature of the rolling surface of the roll at about 120°C, but the process of processing inclined holes with this technology is complicated and difficult; the connecting parts It is difficult to manufacture and install; if the rolling surface of the roll is worn, the entire roll surface must be reprocessed

Embodiment 1

[0020] The utility model relates to a sleeved roller heated by heat conduction oil. The sleeved roll such as figure 1 and figure 2 Shown: including roll body 1, oil guide pipe 2, oil blocking ring 8, roll sleeve 9 and double-channel rotary joint 15.

[0021] Such as figure 1 As shown, the middle cylinder of the roll body 1 is the roll body, and the driven end of the roll body 1 is processed with a central oil passage 10 along the center line. The cylindrical surface of the roll body is symmetrically processed with a left annular oil groove 5 and a right annular oil groove 12, the left annular oil groove 5 is close to the left end of the roll body, the right annular oil groove 12 is close to the right end of the roll body, the left annular oil groove 5 and the left end of the roll body The cylindrical surface between is processed with left sealing groove, and left sealing ring 4 is housed in the left sealing groove. The right sealing groove and the left sealing groove are ...

Embodiment 2

[0025] The utility model relates to a sleeved roller heated by heat conduction oil. Except following technical parameter, all the other are with embodiment 1:

[0026] The left inclined oil passage 3 is inclined to the middle of the roll body, the inclination angle is 10°~15°, and the number of left inclined oil passages 3 is 5 or 7~12;

[0027] The length of the central oil passage 10 is the length of the roll body 1 L 80~90% of

[0028] The distance between the left annular oil groove 5 and the left end face of the roller body is 40-60mm.

[0029] This specific embodiment: after the roller sleeve 9 is fixedly covered on the surface of the roller body, the left annular oil groove 5, the right annular oil groove 12, the oil guide groove 6 and the inner wall of the roller sleeve 9 formed on the surface of the roller body correspondingly form a left annular oil passage , right annular oil passage and oil guide passage; The oil plug ring 8 divides the center oil passage 10 int...

Abstract

The invention relates to a roller shell roller capable of heating with heat conducting oil. According to the technological scheme, a center oil channel (10) is machined in the driven end of a roller body (1), and a left annular oil groove (5) and a right annular oil groove (12) are symmetrically machined in the cylindrical face of the roller body (1). Oil conducting grooves (6) are evenly machined between the left annular oil groove (5) and the right annular oil groove (12). Left slant oil channels (3) are evenly formed in the bottom of the left annular oil groove (5) and right slant oil channels (11) and the left slant oil channels (3) are symmetrically formed. The cylindrical face of the roller body is fixedly sleeved with a roller sleeve (9). The driven end of the roller body (1) is fixedly provided with a double-path rotation adapter (15). An oil conducting pipe (2) is arranged in the center oil channel (10). One end of the oil conducting pipe (2) is installed in the double-path rotation adapter (15). The other end of the oil conducting pipe (2) is fixedly provided with an oil blocking ring (8) which is arranged between the left slant oil channels (3) and the right slant oil channels (11). The roller shell roller capable of heating with the heat conducting oil has the advantages of being capable of evenly controlling the temperature of a rolled face, easy to machine and low in cost.

Description

technical field [0001] The invention belongs to the technical field of rolls. In particular, it relates to a sleeve-type roller heated by heat-conducting oil. Background technique [0002] During the rolling process of lithium battery pole pieces, the compaction density has a great influence on the performance of lithium batteries. The greater the compaction density, the more pole pieces per unit volume, and the greater the capacity of lithium batteries. When the rolling surface (That is, the roll body, the same below) when the temperature is about 120 ° C, the effect of rolling lithium battery pole pieces is the best. The existing general-purpose lithium battery pole piece rolling mill adopts normal temperature rolls, and the lithium battery pole piece is preheated through a heating box before rolling. Since the heating position is far away from the rolling area of ​​the lithium battery pole piece, the heated When the lithium battery pole piece has not reached the lithium...
