Detailed Embodiment

[0016] The following further describes the present utility model with reference to the drawings:

[0017] An automatic peeling tooling for labels. A bottom die 3 for placing release paper 12 is fixed on a die base 8 of a mounting base plate 1. One end of a label 2 is adhesively and peelably attached to the release paper 12 through an adhesive. On both sides of the bottom die 3, there are press wheel groups composed of several press wheels 4. The press wheels 4 are rotatably connected to the ends of adjusting frames 5. The positions of the adjusting frames 5 are adjustably fixed on a base 6. The press wheels 4 cooperate with the side surfaces of the bottom die 3 to press the passing label 2 onto the release paper 12. Above both sides of the bottom die 3, there are pneumatic clamps 9. The pneumatic clamps 9 are connected to connecting arms 10, and the connecting arms 10 are connected to a rotary cylinder 11. The rotary cylinder 11 is fixed on the mounting base plate 1 through a cylinder base 13. Above the middle of the bottom die 3, there is a driving wheel 14. The driving wheel 14 is driven by a motor 15 to drive the release paper 12 and the label 2 to move along the bottom die 3. The press wheel group and the bottom die 3 form a pressing interval for the label 2. The label 2 moves into the pressing interval from the front end and moves out from the rear end. The pneumatic clamp 9 is located above the rear end of the pressing interval. On both sides of the rear end, there are photoelectric sensors 16 fixed on the mounting base plate 1. The photoelectric sensors 16 are connected to a PLC, and the PLC is connected to control the motor 15. When the photoelectric sensors 16 detect that a label 2 has passed, they send a signal to the PLC, and the PLC sends a pause instruction to the motor 15 to stop the detected label 2 under the pneumatic clamp 9 for clamping.

[0018] A strip-shaped hole penetrates through the adjusting frame 5. A fixed pressing plate 7 is provided on the adjusting frame 5. A fastening bolt penetrates through the strip-shaped hole and the adjusting frame 5 and is threadedly connected to the base 6. By adjusting the relative positions of the adjusting frame 5 and the base 6, the tightness of the fit between the press wheel 4 on the adjusting frame 5 and the bottom die 3 is adjusted, and the passing label 2 is pressed on the surface of the release paper 12, so that the label 2 will not be separated and warped from the bent part due to the bending of the release paper 12.

[0019] The driving wheel 14 is rotatably connected to mounting vertical plates 17 on both sides. The tops of the mounting vertical plates 17 are fixed on a support plate 18. The motor 15 is fixed at the bottom of the support plate 18. The output end of the motor 15 is connected to a driving pulley a19. There is a driving pulley b20 at the bottom of the driving pulley a19. A transmission belt 24 is provided between the driving pulley a19 and the driving pulley b20. The driving pulley b20 is connected to the driving wheel 14 through a connecting shaft. A guide post 21 is provided at the end of the support plate 18. The guide post 21 penetrates through and is slidably connected to the support plate 18. The top end of the guide post 21 is fixed with a mounting top plate 22. A cylinder 23 is fixed on the mounting top plate 22. The output end of the cylinder 23 is connected to the support plate 18 located below the mounting top plate 22.

[0020] Before the tooling works, first bend the end of the release paper 12 according to the shape of the bottom mold 3 into a square with an open bottom, then insert both sides of the bent end between the pressure wheel group and the bottom mold 3 and move it under the driving wheel 14. The air cylinder 23 drives the driving wheel 14 to move down and press onto the surface of the release paper 12. The motor 15 drives the driving wheel 14 to rotate. The driving wheel 14, through the frictional force with the release paper 12, pushes the release paper 12 to move horizontally along the bottom mold 3 towards the pneumatic clamp 9. The pressure wheel 4 rotates while being driven by the release paper 12 and the label 2 and presses on both sides of the release paper 12. Cooperating with the pressure of the top driving wheel 14, the release paper passing through the pressing area subsequently is pressed into a square with an open bottom. The photoelectric sensor 16 at the outlet of the pressing area detects in real time whether there is a label 2 passing by. When the label 2 is detected, the motor 15 pauses and the label 2 also stops moving. The rotary air cylinder 11 drives the open pneumatic clamp 9 to move to the position of the label 2. The pneumatic clamp 9 closes to clamp the label 2. The rotary air cylinder 11 drives the pneumatic clamp 9 to rotate towards the bottom mold 3 on both sides and obliquely downward to tear the label 2. The label 2 is separated from the release paper and is transported by the pneumatic clamp 9 to the pasting process at the side of the bottom plate 1. The pasting process takes away the label 2 on the pneumatic clamp 9. After the pneumatic clamp 9 stays at the pasting process for a preset time, it rotates under the drive of the rotary motor 11 to the position above the bottom mold 3 where the label 2 to be taken is waiting, waiting to clamp the next label 2. After the label 2 is taken away, the photoelectric sensor 16 sends a signal to the PLC. The PLC sends an operation instruction to the motor 15. The motor 15 runs and the driving wheel 4 rotates, continuing to push the release paper 12 and the label 2 to move towards the pneumatic clamp 9, and the tooling enters the next working cycle.

[0021] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
