Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0025] This application provides a material storage device for sheet winding before the sheet is wound. This material storage device can temporarily store material for multiple winding machines at the front, increasing the diversity of material storage and ensuring the stability and quality of the sheet during storage.

[0026] like Figure 1-4 As shown, the storage device 100 includes a storage rack 1 and a first floating roller mechanism 2, a second floating roller mechanism 3, a first auxiliary traction mechanism 4, and a second auxiliary traction mechanism 5 installed on the storage rack 1. The first floating roller mechanism 2 is installed near the front end of the storage rack 1, and the first auxiliary traction mechanism 4 is located behind the first floating roller mechanism 2 for unidirectionally pulling the sheet material that passes through the first floating roller mechanism 2 backward. The second floating roller mechanism 3 is installed near the rear end of the storage rack 1, and the second auxiliary traction mechanism 5 is located behind the second floating roller mechanism 3 for unidirectionally pulling the sheet material that passes through the second floating roller mechanism 3 backward.

[0027] like Figure 1 , 2 As shown, the storage rack 1 includes a first support frame 11, a second support frame 12 and a transition frame 13. The first support frame 11 and the second support frame 12 are arranged opposite each other, with the second support frame 12 located behind the first support frame 11. The transition frame 13 is mounted on top of the first support frame 11 and the second support frame 12.

[0028] like Figure 1 , 4 As shown, the transition frame 13 includes a pair of horizontal beams 131 arranged opposite each other and a plurality of transition rollers 132 rotatably mounted between the pair of horizontal beams 131. Each horizontal beam 131 extends in the front-to-back direction, and the front and rear ends of each horizontal beam 131 are respectively connected to the top ends of the first support frame 11 and the second support frame 12. The plurality of transition rollers 132 all extend in the left-to-right direction, and the plurality of transition rollers 132 are arranged at intervals from front to back between the pair of horizontal beams 131.

[0029] like Figure 1 , 2 As shown in Figure 4, the first support frame 11 includes a pair of support legs 111 arranged opposite each other on the left and right sides, and at least a pair of reinforcing beams 112 connected between the pair of support legs 111. The top ends of the pair of support legs 111 are fixedly connected to the ends of a pair of crossbeams 131, respectively. Each support leg 111 extends in the vertical direction, and each reinforcing beam 112 extends in the horizontal direction. At least a pair of reinforcing beams 112 are spaced apart in the vertical direction, thereby strengthening the overall stability and load-bearing capacity of the first support frame 11. At least a pair of first transition guide rollers 113 are rotatably mounted between the pair of first support legs 111. The at least pair of first transition guide rollers 113 are spaced apart in the vertical direction to facilitate the transition of the sheet material entering the storage device 100. The second support frame 12 is identical in structure to the first support frame 11 except that it lacks the first transition guide rollers, and will not be described in detail here.

[0030] The storage rack 1 also includes a first auxiliary support frame 14 and a second auxiliary support frame 15 arranged opposite each other. The first auxiliary support frame 14 is located behind the first support frame 11, such that the first floating roller mechanism 2 is located between the first support frame 11 and the first auxiliary support frame 14. The second auxiliary support frame 15 is located in front of the second support frame 12, such that the second floating roller mechanism 3 is located between the second support frame 12 and the second auxiliary support frame 15. The top ends of the first auxiliary support frame 14 and the second auxiliary support frame 15 are connected to the bottom of a pair of crossbeams 131 to enhance the overall stability of the storage rack 1.

[0031] like Figure 1-3 As shown, the first floating roller mechanism 2 includes a floating aluminum roller 21 extending in the left-right direction and a pair of lifting cylinders 22 mounted on the transition frame 13 opposite to each other. The two ends of the floating aluminum roller 21 are connected to the pair of lifting cylinders 22 and can rotate about its own axis relative to the pair of lifting cylinders 22. The pair of lifting cylinders 22 can synchronously drive the floating aluminum roller 21 to keep it horizontally raised and lowered in the up-down direction.

[0032] In this application, the sheet passes under the floating aluminum roller 21. When the floating aluminum roller 21 moves downward, the movement path of the sheet at the storage device 100 increases, achieving the purpose of storage. When the floating aluminum roller 21 moves upward, the sheet is conveyed backward under the traction of the rear side, realizing the release of the stored sheet. The up and down movement of the floating aluminum roller 21 provides temporary storage for the corresponding rewinding machine on the rear side, facilitating the rewinding and unwinding of the rear rewinding machine and assisting in non-stop rewinding operations.

[0033] Each lifting cylinder 22 is equipped with a proportional valve (not shown in the figure) for adjusting the gas flow rate at its air port. Each lifting cylinder 22 is also equipped with a solenoid valve (not shown in the figure) between itself and the air source. The solenoid valve is used to switch the air path of the corresponding lifting cylinder 22. In this embodiment, the solenoid valve is a two-position five-way solenoid valve.

[0034] When controlling the gas flow rate of the lifting cylinder 22 using a proportional valve, a preset value S1 is first set for the proportional valve. This value S1 corresponds to a certain thrust F of the lifting cylinder 22. When the sum of the thrust F and the weight G of the floating aluminum roller is slightly greater than the tension F of the sheet material... N When the floating aluminum roller 21 descends under the thrust of the lifting cylinder 22, it can lower to store material when rewinding is not fast enough or when there is material buildup during sheet replacement. Once the floating aluminum roller 21 has descended to a certain height and the material buildup is complete, the sheet will generate an upward tension F. Z This tension F ZThe force is less than the weight G of the floating aluminum roller, so when releasing the stored material, a value S2 is applied to the proportional valve. This value S2 corresponds to a thrust F2 in the lifting cylinder 22. Then, the air path is reversed via the solenoid valve. At this time, when the thrust F2 and the tension F... Z When the sum of the forces exceeds the weight G of the floating aluminum roller, the floating aluminum roller 21 will rise, releasing the accumulated sheet. In this way, the floating aluminum roller 21 completes the storage and release of the sheet by continuously rising and falling. Through the setting of the proportional valve, the sheet tension can be precisely controlled to prevent the sheet from being torn or deformed during the winding process, thus ensuring the quality of the sheet.

[0035] In addition, guide components 25 are installed between the two ends of each floating aluminum roller 21 and the corresponding first support frame 11. Each guide component 25 includes a linear guide rail 251 extending in the vertical direction and a linear slider 252 that slides with the linear guide rail 251. The linear guide rail 251 is mounted on the corresponding support leg 111, and the linear slider 252 is connected to the end of the floating aluminum roller 21. When the floating aluminum roller 21 moves up and down in the vertical direction, the sliding engagement between the linear slider 252 and the linear guide rail 251 guides the movement of the floating aluminum roller 21. This not only ensures the stability of material storage and discharging but also avoids jamming caused by asynchronous movement of the lifting cylinders on both sides during the rising or falling of the floating aluminum roller 21.

[0036] The structure and working principle of the second floating roller mechanism 3 are the same as those of the first floating roller mechanism 2, and will not be described in detail here.

[0037] The first auxiliary traction mechanism 4 includes a pair of traction rollers 41 arranged vertically opposite each other and a traction cylinder 42 that is drively connected to the upper traction roller 41. Both traction rollers 41 extend in the left-right direction, and each traction roller 41 has a one-way bearing (not shown in the figure) installed at its end. The traction cylinder 42 is used to drive the upper traction roller 41 to move up and down to clamp the sheet between the pair of traction rollers 41. When the rewinder at the rear winds up the sheet, the pair of traction rollers 41 provide auxiliary traction to prevent the sheet from deviating and the stored material from returning, thus ensuring the quality of the sheet.

[0038] The structure and working principle of the second auxiliary traction mechanism 5 are the same as those of the first auxiliary traction mechanism 4, and will not be described in detail here.

[0039] The first auxiliary traction mechanism 4 is installed on the first auxiliary support frame 14. Its traction roller 41 and the first transition guide roller 113 on the first support frame 11 are respectively on the rear and front sides of the floating aluminum roller 21, which assist the floating aluminum roller 21 in storing material.

[0040] The second auxiliary traction mechanism 5 is installed on the second support frame 12. The second auxiliary support frame 15 is rotatably mounted with a second transition guide roller 151 parallel to the first transition guide roller 113. The second transition guide roller 151 and the traction roller of the second auxiliary traction mechanism 5 are respectively on the front and rear sides of the second floating roller mechanism 3, assisting the storage of material on the floating aluminum roller of the second floating roller mechanism 3.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
