[0023] like Figure 2As shown, a guide rail 23 is installed on the top of the second side plate 22 of the stripping frame 2 by bolts, and a slider 231 is provided on the guide rail 23 to cooperate with it, and the slider 231 can slide along the guide rail 23.

The tensioning servo motor 31 drives the second screw rod 32 to rotate, and the second moving block 321 moves along the second screw rod 32. The clamping cylinder 35 installed on the Z-shaped bracket 33 moves with the second moving block 321, and the Z-shaped feeding clamp 30 clamps the sheet material. The tensioning servo motor 31 drives the feeding clamp 30 to move along the pushing groove 61, which can accurately clamp and transfer the sheet material.

[0025] like Figure 1As shown, a sheet material blocking positioning block 81 is provided on one side of the sheet material carrier 6, and a sheet material blocking pulling positioning block 82 is provided on the other side, and the sheet material carrier 6 is provided with a positioning block guide groove 62. A positioning block pulling cylinder 83 is fixedly installed on the first side plate 12 of the feeder frame 1, and the sheet material blocking pulling positioning block 82 is connected to the piston rod of the positioning block pulling cylinder 83. Guide rods 84 are connected to both sides of the sheet material blocking pulling positioning block 82, and a guide block 85 that cooperates with the guide rod 84 is installed on the first side plate 12 of the feeder frame 1. The piston rod of the positioning block pulling cylinder 83 can push the sheet material blocking pulling positioning block 82 to move along the positioning block guide groove 62. During the movement, the guide rods 84 on both sides move in the guide blocks 85, which can ensure that both ends of the sheet material blocking pulling positioning block 82 move smoothly. During the process of pushing the sheet, the positioning blocks on both sides can prevent the sheet from shifting during its movement. After the sheet is delivered to its place, the piston rod of the positioning block pulling cylinder 83 retracts to drive the sheet-block pulling positioning block 82 away from the sheet without affecting the rotation and stripping of the sheet.

[0026] like Figure 1 As shown, the stripping frame 2 is equipped with an electric eye bracket 91, and the electric eye bracket 91 is equipped with an electric eye 9. The electric eye 9 is located above the edge of the feeding frame 1 on the side of the stripping frame 2. In fact, the electric eye 9 is located above the make way window 0 and on the side of the sheet material carrier 6. The electric eye 9 can sense whether the sheet material attachment is being stripped. The signal is monitored by the electric eye 9 and transmitted to the background control system to control the signal reminder of the coordinated operation of each component.

[0027] The specific working process of the present invention is as follows: the sheet 100 is placed on the sheet carrier 6, the clamping cylinder 35 drives the feed clamp 30 to clamp the left side of the sheet 100, the positioning block extraction cylinder 83 drives the sheet material extraction positioning block 82 to move inward along the positioning block guide groove 62, and the tensioning servo motor 31 drives the second screw 32 to rotate, so that the feed clamp 30 moves forward to the right along the push groove 61, and the sheet 100 is stably transported to the right side of the sheet carrier 6. After the sheet 100 is delivered to the right side, the positioning block extraction cylinder 83 drives the sheet material extraction positioning block 82 to move away from the sheet and reset. At the same time, the clamping cylinder 35 drives the feed clamp 30 to release the sheet 100, and retreats to the left side and resets to the initial position with the drive of the tensioning servo motor 31. The pull-down servo motor 42 drives the sheet stripping and clamping rotating mechanism 5 to move upward and right along with the first moving block 431, and the sheet clamp 50 reaches the clearance window 0, and the sheet clamp 50 is located on the right side of the sheet 100. The piston rod of the clamp forward cylinder 51 extends to drive the base 52 forward, and the upper and lower sheet clamps (501, 502) are driven to the upper and lower sides of the sheet, and the clamp opening cylinder 55 drives the lifting plate 551 to descend so that the sheet clamp 50 closes and clamps the edge of the sheet 100, and the edge of the sheet 100 is not covered by the attached material. The rotating drive cylinder 53 extends the piston rod to push the rack 531, and the gear 532 meshes with the rack 531, and the rotating frame 54 rotates. The sheet material clamp 50 and the clamp opening cylinder 55 fixed on the rotating frame 54 rotate with the rotating frame 54. The sheet material clamp 50 clamps the right end of the sheet material 100 and slowly tilts upward. At this time, the platform drawing cylinder 72 drives the stripping platform 7 to move to the left to the right side of the sheet material carrier 6, and the end edge of the stripping platform 7 is attached to the sheet material 100 and is located below the attached material. The piston rod of the clamp forward cylinder 51 retracts to drive the base 52 and the rotating frame 54 to retreat to the right as a whole, that is, the sheet material clamp 50 clamps the sheet material 100 in an inclined state and retreats. During the movement of the sheet material 100, the pull-down servo motor 42 synchronously drives the sheet material stripping clamping rotating mechanism 5 to move downward as a whole, and the end edge of the stripping platform 7 will first contact the attached material and peel the attached material from the sheet material 100. After the stripping is completed, the platform pulling cylinder 72 drives the stripping platform 7 to retreat rightward and move to the initial position. The pull-down servo motor 42 is continuously driven, so that the sheet clamp 50 clamps the stripped sheet 100 and moves downward. After the stripped sheet 100 can be grabbed by the mechanical arm, the piston rod of the rotation drive cylinder 53 retracts and drives the rack 531 to move rightward, the gear 532 meshes with the rack 531, and the sheet clamp 50 rotates to reset.

[0029] The above are only some embodiments of the present invention.
