It is noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
The embodiment of the utility model provides a battery pole piece press roller, which can effectively prolong the service life of a press roller body, thereby reducing the production cost.
Referring to fig. 1 to 2, a battery pole piece press roller comprises a press roller body 1 and a roller sleeve 2, wherein the roller sleeve 2 is detachably sleeved on the press roller body 1, and the inner peripheral surface of the roller sleeve 2 is attached to the outer peripheral surface of the press roller body 1; the two ends of the roller sleeve 2 are provided with extension parts 21, and the roller sleeve 2 is detachably connected with the press roller body 1 through the extension parts 21.
In this embodiment, the roll sleeve 2 is detachably connected with the roll body 1 through the extension portion 21, wherein the extension portion 21 is a portion not used for rolling the battery pole piece, so that the detachable connection between the roll body 1 and the roll sleeve 2 can be achieved.
After the roller sleeve 2 is excessively worn, the battery pole piece pressing roller can be detached, then the pressing roller body 1 and the roller sleeve 2 are separated, and after the pressing roller body 1 is replaced by a new roller sleeve 2, the battery pole piece pressing roller is reinstalled on the rolling equipment, so that subsequent production can be started.
It should be noted that, because the roller body 1 will not receive too much roller pressure, the service life will be longer, the battery pole piece press roller generally only need to change the roller sleeve 2, has reduced manufacturing cost effectively. In addition, it is also to be noted that the whole battery pole piece compression roller is heavier, and in the structure of adopting this embodiment, only need send the axle sleeve to the producer of polishing polish can, reduced the transportation degree of difficulty.
Alternatively, the extension portion 21 is an arc portion fitted on the outer peripheral surface of the roll body 1; the arc-shaped part is fixedly connected with the compression roller body 1 through a connecting piece 3. Specifically, the arc portion is attached to the outer peripheral surface of the roller body 1, so that attachment between the roller body 1 and the roller sleeve 2 is more stable, and the problem that the connection stability of the roller body 1 and the roller sleeve 2 is poor due to the fact that the extending portion 21 is tilted is avoided.
Alternatively, as shown in fig. 4 and 5, a chute 11 parallel to the center line 100 of the roll body 1 is provided on the outer peripheral surface of the roll body 1; the roller housing 2 has a bar-shaped projection 22 slidably disposed in the chute 11. The center line 100 is a rotation center line of the roll body 1 during the rolling. Preferably, the cross section of the bar-shaped protrusion 22 matches the cross section of the chute 11 on a plane perpendicular to the extending direction of the chute 11. The installation mode of the sliding chute 11 and the strip-shaped protrusions 22 can effectively avoid the relative rotation of the roller sleeve 2 relative to the roller body 1, and the sliding chute 11 is arranged to enable the roller sleeve 2 and the roller body 1 to be positioned and installed rapidly.
Optionally, the connecting piece 3 is a threaded connecting piece, a through hole is formed in the arc-shaped portion, a threaded hole is formed in the compression roller body 1, and a threaded rod of the connecting piece 3 penetrates through the through hole and is in threaded connection with the threaded hole, so that the roller sleeve 2 and the compression roller body 1 are fixedly connected.
In another specific embodiment, as shown in fig. 4, an L-shaped pressing plate 4 is provided on the roll body 1; the L-shaped pressing plate 4 includes a connection plate portion 41 detachably connected to the roll body 1 and a pressing plate portion 42 for pressing the extension portion 21 against the roll body 1; the extension portion 21 abuts against the plate surface of the connection plate portion 41.
The connecting plate 41 is equivalent to positioning the roll sleeve 2, and the pressing force of the pressing plate 42 can effectively prevent the roll sleeve 2 and the roll body 1 from sliding relatively.
In another specific embodiment, as shown in fig. 3, a positioning groove 101 is provided on the roll body 1; the first end of the roller sleeve 2 is provided with a first extension part, and the first extension part is provided with a positioning protrusion 201 matched with the positioning groove 101; the second end of the roll sleeve 2, which is far away from the first end, is provided with a second extension part, and the second extension part is detachably connected with the press roll body 1.
It should be noted that, the positioning groove 101 and the positioning protrusion 201 are provided, so that the rapid positioning between the roll body 1 and the roll sleeve 2 can be rapidly realized, and the installation speed is increased. In addition, the opposite ends of the roll sleeve 2 are fixedly connected with the roll body 1, thereby achieving good fixation.
Optionally, the circumferential surface of the sleeve 2 is provided with a hardened coating. Wherein, the hardened coating is a coating of tungsten carbide or chromium carbide, and the like, and has better wear resistance, thereby being beneficial to prolonging the service life of the roller sleeve 2.
Optionally, the outer circumferential surface of the roller sleeve 2 is provided with convex hulls and/or grooves in an array, and the specific convex hull size or groove size is determined according to the specification of the pole piece to be produced. The structure is that the outer peripheral surface of the roller sleeve 2 can be provided with convex hulls in an array mode, at the moment, another second roller sleeve matched with the roller sleeve 2 exists, and the second roller sleeve array is provided with grooves matched with the convex hulls; the other structure is that the outer peripheral surface of the roller sleeve 2 can be provided with grooves in an array mode, at the moment, another second roller sleeve matched with the roller sleeve 2 exists, and the second roller sleeve array is provided with convex hulls matched with the grooves; in addition, there is a structure in which a convex hull and a concave groove are simultaneously present on the outer peripheral surface of the roll sleeve 2, and there is another second roll sleeve matched with the roll sleeve 2, and the second roll sleeve has a concave groove matched with the convex hull on the roll sleeve 2, and also has a convex hull matched with the concave groove on the roll sleeve 2.
Example two
The battery pole piece rolling equipment is characterized by comprising a battery pole piece rolling roller as in the embodiment I.
Optionally, the battery pole piece rolling device comprises an upper pressing roller assembly and a lower pressing roller assembly which are arranged in parallel, wherein the upper pressing roller assembly and the lower pressing roller assembly both comprise battery pole piece pressing rollers; the outer peripheral surface of the roller sleeve 2 on the upper pressing roller assembly is provided with a groove, and the outer peripheral surface of the roller sleeve 2 on the lower pressing roller assembly is provided with a convex hull matched with the groove.
