The sliding protrusions protrude out of the end face of the winding drum body 11, and when the sliding protrusions are multiple, the sliding protrusions protrude out of the end face of the winding drum body 11 in a multiple mode and are identical in height. And, the sliding protrusion can freely rotate at least in the rotation direction of the winding drum body 11.
When a plurality of winding drums 1 are sequentially arranged on a winding shaft 2 in a close manner to wind the slit pole pieces, the sliding bulge is abutted against the side surface of one winding drum 1 adjacent to the winding drum 1, and the adjacent winding drums 1 can be automatically positioned and separated from each other; and due to the sliding action of the sliding protrusion, the adjacent winding drums can be separated from each other without mutual friction. Meanwhile, the interval between the adjacent winding drums 1 can be kept equal, so that the winding drums 1 on the winding shaft 2 can be in accurate one-to-one correspondence with the cut pole piece strips, the winding drums 1 cannot be biased with the material roll, and the winding of the cut pole pieces can be stably and effectively carried out.
Moreover, on a single side end face of the winding drum body 11, the sliding protrusion includes a plurality of protrusions that are uniformly distributed along the rotation direction of the winding drum body 11. When a plurality of take-up reel 1 leaned on tightly in proper order to install, a plurality of slip archs can effectively ensure the stability that supports and lean on adjacent take-up reel 1, avoid the atress inequality. Moreover, optionally, when the two side end surfaces of the winding drum body 11 of the adopted winding drum 1 are provided with the sliding protrusions, the sliding protrusions on the side end surfaces of the two adjacent winding drums 1 are staggered with each other; when only one side end face of the winding drum body 11 is provided with the sliding protrusions, the sliding protrusions are located on one side of the winding drum 1 along the abutting direction or on one side deviating from the abutting direction, so that a stable abutting relationship is formed, and a space is formed between the adjacent winding drums 1.
Preferably, on a single side end face of the winding drum body 11, the sliding protrusions include three protrusions evenly distributed along the rotation direction of the winding drum body 11. Set up three slip arch on single side end face, when effective guarantee supports the stability that leans on to adjacent a take-up reel 1, make the structure more succinct.
In one embodiment, as shown in fig. 1, the sliding projection is formed by a ball 12 provided on the take-up drum body 11. The rolling balls 12 are embedded in the winding drum body 11 and protrude from the end surface of the winding drum body 11 to form the sliding protrusion. Further, the balls 12 are freely rotatable on the winding drum body 11, including rotation in the rotational direction of the winding drum body 11.
In another embodiment, see fig. 2, the sliding projection is formed by a roller 13 provided on the take-up spool body 11. The end surface of the winding drum body 11 is provided with a roller groove 14, and the roller 13 is arranged in the roller groove 14 through a roller shaft 15 and protrudes out of the end surface of the winding drum body 11 to form the sliding protrusion. Specifically, the axial direction of the roller shaft 15 is along the radial direction of the winding drum body 11, so that the roller 13 can be freely rotated along the rotation direction of the winding drum body 11 through the roller shaft 15 and is installed in the roller groove 13 and protrudes out of the roller groove 13.
Example 2
Referring to fig. 3, the automatically positioned slitting and winding assembly of the present embodiment comprises a winding shaft 2 and a plurality of winding drums 1. The winding drums 1 are sleeved on the winding shaft 2, and the winding drums 1 are sequentially close to each other. Further, the winding drum 1 used was the winding drum described in embodiment 1.
And in a plurality of the winding drum 1, when the sliding protrusion is arranged on only one side end surface of the winding drum body 11, the sliding protrusion is positioned on one side of the winding drum 1 along the closing direction or on one side deviating from the closing direction. In the embodiment, the winding drum body 11 has the sliding protrusion on only one side end surface, and is specifically formed by the rollers 13, and the rollers 13 include three rollers and are uniformly distributed along the rotation direction of the winding drum body 11; when a plurality of winding drums 1 are sequentially tightly sleeved on the winding shaft 2, the rolling wheels 13 are positioned on one side deviating from the tight direction so as to separate the adjacent winding drums 1.
In this embodiment, in the plurality of winding drums 1, the heights of the sliding protrusions of each winding drum 1 protruding from the end surface of the winding drum body 11 are all the same, so that the winding drums 1 are kept at equal intervals.
In addition, the winding shaft 2 is further provided with a reference retainer ring 3 for preventing the plurality of winding drums 1 from sliding left and right along the axial direction of the winding shaft 2 and making the plurality of winding drums 1 abut against each other. In the assembling process, the reference check ring 3 is firstly arranged on the winding shaft 2, then the winding drums 1 are manually sleeved on the winding shaft 2 and pushed to the reference check ring 3 to be tightly attached, and the plurality of winding drums 1 are automatically positioned through the sliding protrusions and keep the same interval, so that the operation is convenient, the efficiency is high, the speed is high, and the positioning is accurate; and when in winding, the adjacent winding drums 1 are automatically positioned and keep equal intervals, so that the winding drums 1 on the winding shaft 2 can be accurately in one-to-one correspondence with the cut pole piece strips, no offset can occur between the winding drums 1 and the material roll 4 (see figure 4), and the winding of the cut pole pieces can be stably and effectively carried out.
