Especially, the third rotating shaft 310, the support rolling release assembly 200 and the flexible curved bending buffer 330 can form a three-point unreeling stress point in cooperation with the use of the support rolling release assembly 200, so that a user can more flexibly adjust the stress required by the superfine fiber cloth during unreeling, and the superfine fiber cloth roll with different specifications can be better adapted to the superfine fiber cloth rolls with different specifications.

In this embodiment, the flexible curved bending buffer 330 is a thin flexible stainless steel member. It can be understood that the thin flexible stainless steel member can generate better deformation and swing, so when the tension of the superfine fiber cloth on the third rotating shaft 310 is larger, the superfine fiber cloth can swing on the flexible curved surface bending buffer member 330 to drive the flexible curved surface bending buffer member 330 to swing so as to release the tension of the superfine fiber cloth, the tension of the superfine fiber cloth in unreeling operation is reduced, the stress of the superfine fiber cloth in the unreeling operation process is uniform, and the adverse phenomenon of the superfine fiber cloth is effectively avoided.

In this embodiment, the bracket 110 includes a first installation area and a second installation area, the height of the second installation area is higher than that of the first installation area, the first rotating shaft 210 and the second rotating shaft 220 are arranged in the first installation area in a side-by-side rotating manner, the third rotating shaft 310 is arranged in the second installation area in a rotating manner, and the horizontal height of the first rotating shaft 210 and the second rotating shaft 220 in the bracket 110 is lower than that of the first installation area in the bracket, so as to ensure that the first rotating shaft 210 and the second rotating shaft can form a supporting and placing limiting area 250 in the first installation area. Specifically, the horizontal heights of the first and second rotation shafts 210 and 220 on the bracket 110 may be set as required for actual production by those skilled in the art.

In one embodiment, the driving end of the first driver 230 is connected to the first rotating shaft 210 to drive the first rotating shaft 210 by the first driver 230, and similarly, in order to drive the second rotating shaft 220 and the third rotating shaft 310 by the second driver 240 and the third driver 320, respectively, in other embodiments, the driving end of the second driver 240 is connected to the second rotating shaft 220, and the driving end of the third driver 320 is connected to the third rotating shaft 310.

In this embodiment, the first driver 230 and the second driver 240 can both drive the first rotation shaft 210 and the second rotation shaft 220 through a linkage assembly. Specifically, in one embodiment, the linkage assembly includes a driving wheel, a driven wheel, and a conveying belt, the driving wheel is connected with the driving end of the first driver 230, the driven wheel is rotatably disposed on the first rotating shaft 210, and the conveying belt is respectively sleeved on the driving wheel and the driven wheel, so as to ensure that the first driver 230 can drive the driven wheel to rotate when driving the driving wheel to rotate, thereby driving the first rotating shaft 210 to rotate.

In one embodiment, the first driver 230, the second driver 240 and the third driver 320 may be motors or rotary cylinders to rotate the first rotation shaft 210, the second rotation shaft 220 and the third rotation shaft 310.

In one embodiment, as shown in fig. 1 and 3, the flexible curved bend buffer 330 is formed with a bend curved buffer 331. It can be appreciated that, since the flexible curved surface bending buffer 330 is formed with the bending curved surface buffer 331, the bending curved surface buffer 331 can provide a good buffering effect for the superfine fiber cloth just coming out from the third rotating shaft 310, so as to effectively avoid the phenomenon that the superfine fiber cloth is easily deformed due to tension caused by excessive tension in the unreeling process.

As shown in fig. 1 and 3, in one embodiment, the bending angle of the bending curved buffer area 331 is 45 ° to 75 °, so as to ensure that the bending curved buffer area 331 can form a proper buffer angle on the support 110, so as to effectively avoid the phenomenon that the superfine fiber cloth is easily deformed due to tension caused by excessive tension in the unreeling process. In addition, the user can also better adapt to the application of the superfine fiber cloth rolls with different specifications by adjusting the bending angle of the bending curved surface buffer zone 331, so that the suitability of the superfine fiber cloth roll feeding buffer device 10 is better improved.

In one embodiment, the highest point 3311 of the curved buffer is located above the support placement limit 250 and the lowest point 3312 of the curved buffer is located below the support placement.

It can be appreciated that, because the highest point 3311 of the curved buffer zone is located above the supporting and placing limiting zone 250, and the lowest point 3312 of the curved buffer zone is located below the supporting and placing zone, and because the third rotating shaft 310 is located above the second rotating shaft 220, the third rotating shaft 310, the second rotating shaft 220 and the curved buffer zone 331 can form a "parabola" with a higher initial section on the frame 100, thus, the tensioning force of the superfine fiber cloth between the supporting and placing limiting zone 250 and the curved buffer zone 331 can be effectively reduced, so as to ensure that the stress of the superfine fiber cloth in the unreeling process is uniform and difficult to generate, and thus, the reject ratio is greatly reduced.

As shown in fig. 3, in one embodiment, the feeding buffer device 10 for the superfine fiber cloth roll further includes a limiting member 400, where the limiting member 400 is disposed adjacent to the supporting and placing limiting region 250, and the limiting member 400 is used for preventing the superfine fiber cloth roll from falling when the supporting and placing limiting region 250 unwinds.

It can be understood that, although the second rotating shaft 220 and the first rotating shaft 210 can form the supporting and placing limiting area 250 with a certain limiting function on the bracket 110, since the superfine fiber cloth roll directly rolls on the supporting and placing limiting area 250 during unreeling, if the superfine fiber cloth roll has a larger diameter, the superfine fiber cloth roll is easy to fall off during unreeling operation. Therefore, the limiting rod is arranged adjacent to the supporting and placing limiting area 250, so that the limiting rod can roll up the superfine fiber cloth in the supporting and placing limiting area 250 to achieve the limiting and blocking effect, and the phenomenon that the superfine fiber cloth rolls fall off when the supporting and placing limiting area 250 is unreeled is effectively prevented.

As shown in fig. 3, in one embodiment, the limiting member 400 includes a first limiting rod 410 and a second limiting rod 420, where the first limiting rod 410 and the first limiting rod 410 are respectively disposed above the supporting and placing limiting region 250 and connected to the bracket 110. It can be appreciated that the first stop lever 410 and the first stop lever 410 are respectively disposed above the supporting and placing stop zone 250, so that the first stop lever 410 and the second stop lever 420 can stop the supporting and placing stop zone 250, thereby effectively preventing the phenomenon that the superfine fiber cloth roll with larger diameter easily falls off during unreeling.

In one embodiment, the first stop lever 410 is rotatably disposed on the bracket 110. It can be appreciated that, since the first stop lever 410 is rotatably disposed on the bracket 110, so that the first stop lever 410, the first rotation shaft 210, the second rotation shaft 220 and the bracket 110 can rotate, the friction between the first stop lever 410 and the superfine fiber cloth roll with larger diameter can be effectively reduced by adopting a rotation manner with respect to the fixing manner of the first stop lever 410, and thus, under the condition of reducing the abrasion to the superfine fiber cloth roll with larger diameter, a better stop effect on the superfine fiber cloth roll with larger diameter is ensured.

Similarly, in other embodiments, the second limiting rod 420 is rotatably disposed on the bracket 110, so as to effectively reduce the abrasion between the second limiting rod 420 and the superfine fiber cloth roll with larger diameter, and especially, the second limiting rod 420 is rotatably disposed on the bracket 110 in cooperation with the first limiting rod 410, so that the first limiting rod 410 and the second limiting rod 420 can roll up the superfine fiber cloth roll with larger diameter in the supporting and placing limiting area 250 to perform the rolling arc limiting function, so as to well ensure the stress uniformity of the superfine fiber cloth roll with larger diameter during unreeling, and thus effectively avoid the adverse phenomena such as deformation.

As shown in fig. 1 and 3, in one embodiment, the feeding and buffering device 10 for the superfine fiber cloth roll further includes a plurality of universal wheels 500, and each universal wheel 500 is rotatably disposed at the bottom of the frame 100. It can be appreciated that by adding a plurality of universal wheels 500 at the bottom of the frame 100, the user can quickly move, which is labor-saving and convenient to operate.

As shown in fig. 3, in one embodiment, the elastic buffer assembly 300 further includes a reinforced limit support 600, where the reinforced limit support 600 is disposed below the flexible curved bending buffer 330, connected to the buffer frame 120, and movably abutted to the bottom of the flexible curved bending buffer 330. It can be appreciated that, since the flexible curved surface bending buffer 330 is thinner and can swing under a larger external force, the bending angle of the bending curved surface buffer 331 can be within a preset angle range during the unreeling operation, so that the phenomenon that the superfine fiber cloth is stressed unevenly is easy to occur. Therefore, by additionally arranging the reinforced limit support 600 below the lowest point of the flexible curved surface bending buffer 330, the reinforced limit support 600 can provide a better supporting and limit function for the flexible curved surface bending buffer 330, so as to better ensure that the bending angle of the bending curved surface buffer 331 of the flexible curved surface bending buffer 330 is still within the range of a preset angle during unreeling, thereby effectively avoiding the phenomenon of uneven stress on the superfine fiber cloth.

The present disclosure also provides a production device for a superfine fiber cloth roll, comprising the superfine fiber cloth roll feeding buffer device 10 of any one of the embodiments. It can be understood that the production equipment for the superfine fiber cloth rolls further comprises a bleaching and dyeing device, a drying device, a shaping device and a conveying device, wherein the superfine fiber cloth roll feeding buffer device 10, the bleaching and dyeing device, the drying device and the shaping device are sequentially arranged along the conveying direction of the conveying device, so that the superfine fiber cloth roll feeding buffer device 10 can provide non-deformed superfine fiber cloth for the subsequent process, the structure is simple, the stress of the unreeling operation is improved to be uniform, the phenomenon that the superfine fiber cloth is easy to deform in the unreeling operation of the feeding process is effectively reduced, the defective rate of the superfine fiber cloth is reduced, and the suitability of the superfine fiber cloth roll feeding buffer device 10 is improved, so that the unreeling operation requirements of superfine fiber cloth rolls with different specifications are better adapted.

2) Because the third rotating shaft 310 is rotatably disposed on one side of the support 110 near the buffer frame 120 and is located above the second rotating shaft 220, a certain height difference can be formed between the third rotating shaft 310 and the second rotating shaft 220, so as to reduce the tension force of the superfine fiber cloth between the supporting and placing limiting area 250 and the third rotating shaft 310, so as to reduce the tension force of the superfine fiber cloth in the unreeling operation, better ensure that the superfine fiber cloth is uniformly stressed in the unreeling operation, and simultaneously cooperate with the flexible curved surface bending buffer 330 to be disposed below the third rotating shaft 310, so that the third rotating shaft 310 and the flexible curved surface bending buffer 330 can form a certain height difference, and the superfine fiber cloth can freely drop into the flexible curved surface bending buffer 330 under the action of gravity, so that the superfine fiber cloth is ensured to be stretched in the flexible curved surface buffer 330 under the condition of no tension, further ensure that the superfine fiber cloth is uniformly stressed in the unreeling operation, and reduce the defective rate of the superfine fiber cloth in the unreeling operation. Especially, the third rotating shaft 310, the support rolling release assembly 200 and the flexible curved bending buffer 330 can form a three-point unreeling stress point in cooperation with the use of the support rolling release assembly 200, so that a user can more flexibly adjust the stress required by the superfine fiber cloth during unreeling, and the superfine fiber cloth roll with different specifications can be better adapted to the superfine fiber cloth rolls with different specifications.
