[0025] The automatic roll changing mechanism 1 comprises a machine wall 101 and a feeding shaft 110, the outside of the feeding shaft 110 is provided with a raw material roll 113, the bottom side of the machine wall 101 is provided with a supporting plate 102, the inside of the supporting plate 102 is provided with a speed reducer motor 103, the inside of the automatic roll changing mechanism 1 is connected with a chain wheel one 104, a chain wheel two 105 and a chain wheel three 106, one of the chain wheel ones 104 is connected with the speed reducer motor 103, the two chain wheel ones 104 are commonly provided with a connecting rod 114, the outside of the chain wheel one 104 and the chain wheel two 105 is commonly provided with a chain one 107, the outside of the chain wheel two 105 and the chain wheel three 106 is commonly provided with a chain two 108, the outside of the chain two 108 is provided with three groups of roll fixing assemblies 109, the inside of the machine wall 101 is provided with a laser range finder 111 and a third photoelectric sensor 112;

[0026] The roll fixing assembly 109 comprises a mounting plate 1091 mounted on the outside of the chain two 108, the top of the mounting plate 1091 is provided with a roll shaft seat 1092 and a second pneumatic cylinder 1093, one end of the top of the roll shaft seat 1092 is connected with a connecting shaft 1094, the outside of the connecting shaft 1094 is provided with a shaft seat cover 1095, the outside of the shaft seat cover 1095 is provided with a mounting seat 1096, the telescopic end of the second pneumatic cylinder 1093 is provided with a connecting plate 1097, and the connecting plate 1097 is rotationally connected in the inside of the mounting seat 1096.

[0027] When starting production, the second pneumatic cylinder 1093 arranged at the first roll fixing assembly 109 is started, the telescopic end of the second pneumatic cylinder 1093 drives the connecting plate 1097 to move downward, the connecting plate 1097 moves in the mounting seat 1096, at this time, the mounting seat 1096 drives the shaft seat cover 1095 to move on the top of the roll shaft seat 1092, until the shaft seat cover 1095 is opened; at this time, the turnover trolley 2 sends the required raw material roll 113 to the site from the raw material warehouse or the previous process, the telescopic end of the first pneumatic cylinder 5 arranged at the turnover trolley 2 drives the raw material roll 113 transported on the top to move upward, the feeding shaft 110 at the raw material roll 113 corresponds to the position of the opened roll shaft seat 1092, the telescopic end of the first pneumatic cylinder 5 drives the feeding shaft 110 to move to the roll shaft seat 1092, at this time, the telescopic end of the second pneumatic cylinder 1093 is reset, the feeding shaft 110 is fixed between the roll shaft seat 1092 and the shaft seat cover 1095; after the transported raw material roll 113 is placed, the telescopic ends of the two first pneumatic cylinders 5 are lowered, the turnover trolley 2 moves outward to continue to run a new raw material roll 113 or the previous process; the roll fixing assembly 109 and the placing seat 12 are staggered, which is convenient for the handover of the feeding shaft 110;

[0028] After the raw material roll 113 is placed, the speed reducer motor 103 drives the chain wheel one 104 to rotate, and the two chain wheels one 104 are driven to rotate simultaneously through the connecting rod 114. The two chain wheels two 105 are driven to rotate through the two chains one 107, and the three groups of raw material roll fixing assemblies 109 on the chains two 108 move at this time. The raw material roll 113 at the first raw material roll fixing assembly 109 is transported to the second raw material roll fixing assembly 109, and the unwinding work starts at this time. At this time, the speed reducer motor 103 stops working. When the laser range finder 111 detects that the diameter of the raw material roll 113 is less than the specified value, the speed reducer motor 103 continues to work, and the trolley 2 starts to place the new raw material roll 113 on the first two raw material roll fixing assemblies 109. After the new raw material roll 113 is placed, the trolley 2 is lowered to the required height and moves inward to the last bottom raw material roll fixing assembly 109 to butt joint the finished unwinding shaft 110.

[0029] When the third photoelectric sensor 112 is inducted by the unwinding shaft 110, the trolley 2 stops. When the raw material roll 113 in the second raw material roll fixing assembly 109 is finished, the worker butt joints the new raw material roll 113 with the old raw material roll 113, starts the speed reducer motor 103, and transports the new raw material roll to the second raw material roll fixing assembly 109 for unwinding work. At the same time, the original second raw material roll fixing assembly 109 also moves to the position of the third raw material roll fixing assembly 109. When the first photoelectric sensor 6 detects the finished unwinding shaft 110, the first pneumatic cylinder 5 is started to correspond the position of the unwinding shaft 110 and the placing seat 12. At this time, the second photoelectric sensor 14 is inducted, and the second pneumatic cylinder 1093 of the corresponding raw material roll fixing assembly 109 opens the shaft seat cover 1095. At this time, the unwinding shaft 110 falls on the top of the placing seat 12.

[0030] Embodiment two

[0031] As Figures 1 to 7 In this embodiment two, other structures are unchanged, and different from embodiment one is that in order to avoid the trolley 2 from falling when transporting the raw material roll 113, when the unwinding shaft 110 is on the top of the placing seat 12, the pressure sensor 13 senses the change of pressure, and at this time the pressure sensor 13 sends a signal to the double-head electric push rod 8. The two ends of the double-head electric push rod 8 are connected through the connecting frame 9 to drive the positioning plate 10 to move towards the unwinding shaft 110. The anti-skid pads 11 on one side of the two positioning plates 10 can clamp and fix the unwinding shaft 110. This operation can better transport the unwinding shaft 110. The anti-skid pads 11 are made of rubber material, which can increase the friction and better fix the unwinding shaft 110.
