[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: An unwinding structure of a vertical flexible packaging machine includes an unwinding equipment working platform 1; in order to be able to clamp different-sized coils for unwinding, support legs 9 are installed on the unwinding equipment working platform 1, a mounting seat 5 is installed on the support legs 9, a rotating mechanism 3 is provided on the mounting seat 5, a clamping mechanism 2 is provided on one side of the mounting seat 5 of the rotating mechanism 3, and a tensioning mechanism 4 is provided on the unwinding equipment working platform 1. Different coils are clamped by the clamping mechanism 2, continuous unwinding is performed by the rotating mechanism 3, and the tightness of the unwinding is adjusted by the tensioning mechanism 4.

[0023] In order to achieve the function of clamping coils of different sizes, the clamping mechanism 2 includes a first clamping sleeve 200 and a second clamping sleeve 206. Both the first clamping sleeve 200 and the second clamping sleeve 206 are installed above the working platform 1 of the unwinding device. A first rotating support seat 201 is installed on the first clamping sleeve 200. A first support seat rotating shaft 202 is installed on the first rotating support seat 201. A first connecting rod 203 is installed on the first support seat rotating shaft 202. A pressing block 204 is installed on the first connecting rod 203. A rubber pad 205 is installed on the pressing block 204. A second support seat rotating shaft 210 is installed on the second rotating support seat 209. A second connecting rod 211 is installed on the second support seat rotating shaft 210. The first connecting rod 203 and the second connecting rod 211 are installed with the same connecting rotating shaft 212. A second sleeve groove 207 is opened on the second clamping sleeve 206. A second sleeve mounting ring 208 is installed in the second sleeve groove 207. The second rotating support seat 209 is installed on the second sleeve mounting ring 208. A sleeve rotating hole 213 is opened on the second clamping sleeve 206. Holes are opened on the first rotating support seat 201 and the second rotating support seat 209. The first support seat rotating shaft 202 is installed in the hole on the first rotating support seat 201. The second support seat rotating shaft 210 is installed in the hole on the second rotating support seat 209. The rotating mechanism 3 includes a rotating main shaft 300. The rotating main shaft 300 is installed on the mounting seat 5. A rotating motor 301 is installed on one side of the rotating main shaft 300. A motor rotating shaft 302 is installed on the rotating motor 301. A motor support plate 303 is installed on one side of the mounting seat 5. The rotating motor 301 is installed on the motor support plate 303. A rotating groove 8 is opened on the mounting seat 5. The rotating main shaft 300 is installed in the rotating groove 8. A fixing plate 6 is installed on the mounting seat 5. A fixing bolt 7 is installed on the fixing plate 6. The hollow shaft core of the coil is inserted onto the rotating main shaft 300. A tool is inserted into the sleeve rotating hole 213 to rotate the second clamping sleeve 206. At this time, the rotating main shaft 300 is locked by the rotating motor 301 and will not rotate. The second clamping sleeve 206 moves on the thread of the rotating main shaft 300. When the second clamping sleeve 206 moves, the second clamping sleeve 206 drives the second sleeve mounting ring 208 to move. When the second sleeve mounting ring 208 moves, it drives the second rotating support seat 209 to move. The second rotating support seat 209 drives the second support seat rotating shaft 210 to move. When the second support seat rotating shaft 210 moves, it pulls the second connecting rod 211. The second connecting rod 211 pulls the connecting rotating shaft 212. The connecting rotating shaft 212 pulls the first connecting rod 203. One end of the first connecting rod 203 rotates on the first rotating support seat 201 through the first support seat rotating shaft 202, and the other end is pulled by the connecting rotating shaft 212, resulting in a change in the angle of the first connecting rod 203. When the angle between the first connecting rod 203 and the rotating main shaft 300 gradually decreases, the pressing block 204 descends. When the angle of the first connecting rod 203 gradually expands, the pressing block 204 rises, so that the pressing block 204 fits the inside of the pipe fitting, thereby achieving the effect of clamping by tightly attaching the pressing block 204 to the inner wall of the pipe fitting.

[0024] The working principle is as follows: Insert the hollow core of the coil into the rotating main shaft 300. Use a tool to insert into the sleeve rotation hole 213 and rotate the second clamping sleeve 206. The rotating main shaft 300 is locked by the rotating motor 301 and will not rotate at this time. The second clamping sleeve 206 moves on the thread of the rotating main shaft 300. When the second clamping sleeve 206 moves, the second clamping sleeve 206 drives the second sleeve mounting ring 208 to move. When the second sleeve mounting ring 208 moves, it drives the second rotating support base 209 to move. The second rotating support base 209 drives the second support base rotating shaft 210 to move. When the second support base rotating shaft 210 moves, it pulls the second connecting rod 211. The second connecting rod 211 pulls the connecting rotating shaft 212. The connecting rotating shaft 212 pulls the first connecting rod 203. One end of the first connecting rod 203 rotates on the first rotating support base 201 through the first support base rotating shaft 202, and the other end is pulled by the connecting rotating shaft 212, resulting in a change in the angle of the first connecting rod 203. When the angle between the first connecting rod 203 and the rotating main shaft 300 gradually decreases, the pressing block 204 descends. When the angle of the first connecting rod 203 gradually expands, the pressing block 204 ascends, so that the pressing block 204 fits the inside of the pipe fitting, thereby achieving the effect of clamping by tightly attaching the pressing block 204 to the inner wall of the pipe fitting. Pull out one end of the coil, place the pulled-out coil above the first tensioning rolling sleeve 405, then pull the coil through the lower part of the second tensioning rolling sleeve 405, and then connect the coil port to an external winding device. Drive the tensioning screw rod 402 to rotate through the tensioning motor 401, so that the tensioning moving block 403 moves up and down on the tensioning screw rod 402. When the two tensioning rolling sleeves 405 move away from each other, the coil can be tightened to avoid the coil being too loose and affecting the subsequent unwinding effect.

[0025] Embodiment 2: As Figures 1-4 , in order to tension the pulled-out coil, the tensioning mechanism 4 includes a tensioning bracket 400. A tensioning motor 401 is installed on the tensioning bracket 400. A tensioning screw rod 402 is installed on the tensioning motor 401. A tensioning moving block 403 is installed on the tensioning screw rod 402. A tensioning fixed rod 404 is installed on one side of the tensioning moving block 403. A tensioning rolling sleeve 405 is installed on the tensioning fixed rod 404. Pull out one end of the coil, place the pulled-out coil above the first tensioning rolling sleeve 405, then pull the coil through the lower part of the second tensioning rolling sleeve 405, and then connect the coil port to an external winding device. Drive the tensioning screw rod 402 to rotate through the tensioning motor 401, so that the tensioning moving block 403 moves up and down on the tensioning screw rod 402. When the two tensioning rolling sleeves 405 move away from each other, the coil can be tightened to avoid the coil being too loose and affecting the subsequent unwinding effect. The other features are the same as those in Embodiment 1.
