[0037] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] See also Figure 1 , Figure 1 A schematic structural diagram of a winding structure 10 provided in an embodiment of the present invention when applied to a slitting device 100.

[0039] The embodiment of the present invention provides a winding structure 10, which has the characteristics of good winding effect. The winding structure 10 can be applied to a processing device for outputting narrow materials such as a slitting device 100. Of course, the slitting device 100 can also be used independently.

[0040] When the winding structure 10 is applied to the slitting device 100, the slitting mechanism 20 of the slitting device 100 is used to slit the slit material 900 to form a plurality of narrow strips 910, and the plurality of narrow strips 910 are wound up by the winding structure 10 to stably and properly wind up the plurality of narrow strips. Since the slitting device 100 adopts the winding structure 10 provided by the embodiment of the present invention, the slitting device 100 also has the characteristic of good winding effect.

[0041] The structural composition, working principle and beneficial effects of the winding structure 10 provided in an embodiment of the present invention will be specifically introduced below.

[0042] Please continue to refer to the figure and Figure 2 , Figure 2 The schematic diagram of the structure of the winding structure 10 provided in the embodiment of the present invention when applied to the slitting device 100 is shown in another perspective.

[0043] The winding structure 10 includes an unfolding mechanism 12 and a winding mechanism 11, wherein the winding mechanism 11 is used to wind up a plurality of narrow strips 910 slit by the slitting mechanism 20 of the slitting device 100, and the unfolding mechanism 12 is arranged close to the winding mechanism 11, and the unfolding mechanism 12 is used for allowing the plurality of narrow strips 910 to pass through the unfolding mechanism 12, so that the plurality of narrow strips 910 are conveyed to the winding mechanism 11 at intervals, so that the winding mechanism 11 can wind up the plurality of separated narrow strips 910, so that each narrow strip 910 can be rolled up more evenly, thereby improving the winding effect of the winding structure 10.

[0044] The winding part of the existing slitting device 100 directly winds up the narrow strip 910, and the narrow strips 910 affect each other, resulting in a poor winding effect. In addition, in this embodiment, the unfolding structure is arranged between the slitting mechanism 20 and the winding mechanism 11, so that the narrow strip 910 output by the slitting mechanism 20 can be unfolded by the unfolding mechanism 12.

[0045] Please continue reading Figure 1 and Figure 2 , and see Figure 3 and Figure 4 , Figure 3 for Figure 1 A schematic diagram of the structure enlarged at I in the middle. Figure 4 for Figure 2 Schematic diagram of the enlarged structure at II in the middle.

[0046] The winding mechanism 11 also includes a winding shaft 111, on which a plurality of winding sections (not shown) are provided, and the plurality of winding sections are used to wind up the plurality of narrow strips 910 one by one. The unfolding mechanism 12 includes an unfolding member 121, which is arranged in a strip shape, and a plurality of unfolding openings 1212 are evenly arranged along the length direction of the unfolding member 121, and the plurality of unfolding openings 1212 are used to allow the plurality of narrow strips 910 to pass through one by one, so that the plurality of narrow strips 910 are separated, and the plurality of narrow strips 910 correspond one by one to the plurality of winding sections. In other words, the unfolding member 121 evenly unfolds the plurality of narrow strips 910 through the evenly arranged unfolding openings 1212 thereon, so that the narrow strips 910 are evenly distributed on the winding shaft 111, further improving the winding effect.

[0047] It should be noted that, in this embodiment, the unfolding member 121 is provided with a plurality of unfolding rods 1211, and the plurality of unfolding rods 1211 are evenly spaced along the top surface of the unfolding member 121, and the gap between two adjacent unfolding rods 1211 is an unfolding opening 1212, or in other words, the unfolding opening 1212 is an upward notch, so that the narrow band 910 can be loaded into the unfolding opening 1212, and the winding structure 10 can be adjusted. Of course, in other embodiments, the unfolding opening 1212 can also be other structures, such as a plurality of through holes opened on the unfolding member 121.

[0048] In addition, in this embodiment, the winding shaft 111 can be a slip shaft. After the unfolding mechanism 12 evenly separates the multiple narrow bands 910, it is convenient for the narrow bands 910 to correspond to the convex point positions of the slip ring, so that each narrow band 910 is evenly distributed at the desired position of the slip ring, further improving the winding effect of the winding structure 10.

[0049] Furthermore, the unfolding mechanism 12 may also include a positioning member 122, which is arranged between the unfolding member 121 and the winding shaft 111, and the positioning member 122 is also arranged in a strip shape, and a plurality of positioning openings 1223 are evenly spaced along the length direction of the positioning member 122, and the plurality of positioning openings 1223 correspond one-to-one to the plurality of winding sections, and the plurality of positioning openings 1223 are used for allowing the plurality of narrow bands 910 to pass through one by one, so that the position of the narrow band 910 is limited by the positioning openings 1223, so that the plurality of narrow bands 910 correspond one-to-one to the plurality of winding sections. In other words, after the slit narrow band 910 is unfolded to the desired width by the unfolding member 121, the plurality of narrow bands 910 are further positioned by the positioning member 122 so that the narrow band 910 is at the convex point position of the differential ring, so that each narrow band 910 is evenly distributed at the desired position of the differential ring, so that the narrow band 910 is accurately positioned at the convex point position of the differential ring, further improving the winding effect of the winding structure 10.

[0050] It should be noted that, in the present embodiment, the positioning member 122 is provided with a plurality of positioning rings 1221 and positioning rods 1222, the positioning member 122 is a columnar structure, a plurality of positioning rings 1221 are evenly spaced and sleeved on the positioning member 122, a plurality of positioning rods 1222 are arranged one by one on the positioning rings 1221 along the positioning member 122, and are arranged in a row, the gap between two adjacent positioning rods 1222 and the interval between two adjacent positioning rings 1221 together form a positioning opening 1223, or in other words, the positioning opening 1223 is an upward notch, so that the narrow band 910 can be loaded into the positioning opening 1223, and the winding structure 10 can be adjusted. Of course, in other embodiments, the positioning opening 1223 can also be other structures, such as a plurality of through holes opened on the positioning member 122.

[0051] Furthermore, the unfolding member 121 is rotatably arranged, and the rotation plane of the unfolding member 121 is parallel to the winding shaft 111, and is also parallel to the conveying direction of the narrow band 910 after passing through the unfolding member 121. In other words, the unfolding member 121 can rotate on a plane parallel to the conveying plane of the narrow band 910 after passing through the unfolding member 121, so that the width of the plurality of unfolding openings 1212 in the conveying direction of the narrow band 910 after passing through the unfolding member 121 can be changed by adjusting the orientation of the unfolding member 121, thereby adjusting the intervals between the plurality of narrow bands 910 passing through the unfolding member 121, so as to adapt to the winding of narrow bands 910 of different widths or the winding of winding shafts 111 of different sizes or types.

[0052] It should be noted that, in this embodiment, the unfolding mechanism 12 further includes an unfolding plate 123, which is parallel to the conveying direction of the narrow band 910 and the winding shaft 111, and an adjustment hole 1231 is provided on the unfolding plate 123, and the adjustment hole 1231 is a curved and extended strip hole. The unfolding member 121 is provided with two connecting parts 1213, which are arranged at intervals along the length direction of the unfolding member 121, and the two connecting parts 1213 can be movably arranged in the adjustment hole 1231, so that the unfolding member 121 can be rotatably arranged between the slitting mechanism 20 and the winding mechanism 11, and then the position of the unfolding member 121 can be adjusted by adjusting the positions of the two connecting parts 1213 in the strip hole, so as to achieve the purpose of adjusting the interval between adjacent narrow bands 910. It is movably connected to the adjustment hole 1231 through the two connecting parts 1213 to improve the stability of the unfolding member 121 in maintaining its own position.

[0053] Furthermore, the adjustment hole 1231 may include a first adjustment section 12311 and a second adjustment section 12312 connected in sequence, wherein the extension direction of the first adjustment section 12311 is perpendicular to the winding shaft 111, and the second adjustment section 12312 extends along an arc. The two connecting parts 1213 are respectively arranged at the two ends of the unfolding member 121, and are respectively movably arranged at the first adjustment section 12311 and the second adjustment section 12312. In this way, when adjusting the orientation of the unfolding member 121, one end of the unfolding member 121 moves roughly along the first adjustment section 12311, and the other end of the unfolding member 121 moves along the second adjustment section 12312, so that during the adjustment process, the narrow band 910 only expands or closes the spacing on one side of the first adjustment section 12311, for example, in Figure 3 When the unfolding member 121 is adjusted, the narrow band 910 is unfolded or retracted below the first adjustment section 12311 .

[0054] It should be noted that, in this embodiment, the first adjustment section 12311 is connected to the end of the second adjustment section 12312 away from the reel 111. In other words, the first adjustment section 12311 is arranged close to the slitting mechanism 20, and the second adjustment section 12312 is arranged close to the reel 111. In this way, when the interval between the narrow bands 910 is increased, Figure 3 As shown, the end of the unfolding member 121 close to the slitting mechanism 20 moves away from the slitting mechanism 20 along the first adjustment section 12311, so that the distance between the unfolding member 121 and the slitting mechanism 20 becomes larger, thereby reducing the impact on the slitting action when the unfolding amplitude is increased, and when the interval between the narrow bands 910 is reduced, as shown in FIG. Figure 3 As shown, one end of the unfolding member 121 close to the slitting mechanism 20 moves along the first adjustment section 12311 close to the slitting mechanism 20, so that the distance between the unfolding member 121 and the slitting mechanism 20 as a whole becomes smaller, and when the unfolding range is reduced, its influence on the slitting action is smaller.

[0055] Further, the unfolding mechanism 12 may also include a first guide roller 1251 and a second guide roller 1252, wherein the first guide roller 1251 and the second guide roller 1252 are respectively arranged on a side of the unfolding member 121 away from the winding shaft 111 and a side close to the winding shaft 111, in other words, the first guide roller 1251 is arranged close to the slitting mechanism 20, the second guide roller 1252 is arranged close to the winding shaft 111, and the unfolding member 121 is arranged between the first guide roller 1251 and the second guide roller 1252, and the first guide roller 1251 and the second guide roller 1252 are used to guide the conveying path of the narrow band 910, so that the plane where the multiple narrow bands 910 between the first guide roller 1251 and the second guide roller 1252 are located is parallel to the unfolding member 121, as shown in FIG. Figure 4 As shown, the unfolding member 121 can unfold the multiple narrow strips 910 stably.

[0056] Moreover, in this embodiment, the positioning member 122 is located between the unfolding member 121 and the second guide roller 1252, so that the narrow band 910 is transported to the winding shaft 111 through the second guide roller 1252 after being positioned. In this way, it can be ensured that the width direction of the narrow band 910 transported to the winding shaft 111 is parallel to the winding shaft 111, thereby further improving the winding effect of the winding structure 10.

[0057] In addition, in this embodiment, the winding structure 10 may include two unfolding mechanisms 12 and two winding mechanisms 11, and the two unfolding mechanisms 12 and the two winding mechanisms 11 correspond to each other, and the two unfolding mechanisms 12 are arranged up and down, and the two winding shafts 111 are arranged up and down. After the plurality of narrow bands 910 are separated by the upper and lower unfolding mechanisms 12, they are wound up by the upper and lower winding mechanisms 11. Thus, the slit narrow band 910 is divided into two strands for unfolding and winding, and the unfolding range is reduced. Of course, in other embodiments, other numbers of unfolding mechanisms 12 and winding mechanisms 11 may also be included.

[0058] The working principle of the winding structure 10 provided in the embodiment of the present invention is:

[0059] The winding structure 10 includes an unfolding mechanism 12 and a winding mechanism 11. The winding mechanism 11 is used to wind up the multiple narrow strips 910 slit by the slitting mechanism 20 of the slitting device 100. The unfolding mechanism 12 is arranged close to the winding mechanism 11, and the unfolding mechanism 12 is used for allowing the multiple narrow strips 910 to pass through the unfolding mechanism 12, so that the multiple narrow strips 910 are conveyed to the winding mechanism 11 at intervals, so that the winding mechanism 11 can wind up the multiple separated narrow strips 910, so that each narrow strip 910 can be rolled up more evenly, thereby improving the winding effect of the winding structure 10.

[0060] In summary, the embodiment of the present invention provides a winding structure 10, which has the characteristic of good winding effect.
