[0019] The utility model is further described below in conjunction with specific embodiments and drawings.

The unwinding device 4 is unwinding while the winding device 3 is winding, thereby achieving the effect of conveying the film. At the same time, the punching device 2 punches holes in the film. It is the structure and principle of a conventional roll-to-roll automatic punching machine.

[0021] A panel 5 is arranged on the base 1, and a main sliding hole 51 is arranged in the middle of the panel 5. The punching device 2 passes through the main sliding hole 51 and is exposed outside the upper end of the panel 5, and the bottom surface of the punching position 20 in the punching device 2 is higher than the upper end surface of the panel 5 or flush with the upper end surface of the panel 5, so that after the diaphragm passes through the punching position 20, it can be stably positioned on the bottom surface of the punching position 20, thereby achieving high-quality punching; the panel 5 is provided with two groups of first adsorption holes 52 and second adsorption holes 53 for adsorbing and fixing the diaphragm, and the two groups of first adsorption holes 52 and second adsorption holes 53 are respectively distributed on both sides of the main sliding hole 51 and close to the main sliding hole 51; the bottom of the panel 5 is provided with a first negative pressure device and a second negative pressure device that can generate negative pressure, and the first negative pressure device and the second negative pressure device are respectively assembled corresponding to the first adsorption hole 52 and the second adsorption hole 53. The utility model adopts the first adsorption hole 52 and the second adsorption hole 53 to adsorb and position the front and rear ends of the diaphragm passing through the punching position 20 in the punching device 2. The positioning is stable and reliable, which solves the technical problem that the prior art adopts the lifting cylinder and the clamping plate that may not be able to stably press the diaphragm. At the same time, there is no need to adopt a relatively complex clamping structure composed of a lifting cylinder and a clamping plate. The utility model has a simpler structure and lower cost, and can also achieve stable and reliable positioning relative to the diaphragm, thereby ensuring the quality of subsequent punching, making the utility model extremely competitive in the market.

[0022] There are two punching devices 2, which are symmetrically distributed in the main sliding hole 51, and are used to punch holes on both sides of the diaphragm at the same time to achieve the purpose of double-sided punching.

The technology of using a servo motor in conjunction with a positive and negative thread screw to drive two objects to move toward each other or in the opposite direction is a conventional technology in the field of motor drive.

[0024] The panel 5 is also provided with at least one group of first sliding holes 541 and second sliding holes 542 distributed in the same straight line and located between the main sliding hole 51 and the winding device 3.

The interval between the first limiting wheel 543 and the second limiting wheel 544 is equivalent to the width of the diaphragm. The first limiting wheel 543 and the second limiting wheel 544 cooperate to limit the diaphragm, thereby preventing the diaphragm from running off during the transmission process. At the same time, the first limiting wheel 543 and the second limiting wheel 544 are both in point contact with the outer edge of the diaphragm, and the contact area and friction are small. They will not cause damage to the edge of the diaphragm, thereby ensuring product quality. The first limiting wheel 543 is sleeved on the connecting rod, a handle is provided at the upper end of the connecting rod, a threaded section is provided at the lower end of the connecting rod, a nut is spirally installed on the threaded section, and the nut is placed on the lower end surface of the panel 5.

The driven roller 63 is clamped relative to the active roller 62 under the action of the spring pressing module 64. Both ends of the driven roller 63 are installed in the slide groove 611 at the upper end of the frame 61 through a sliding seat 631, and a screw hole is set at the upper end of the sliding seat 631. A screw rod 641 that can slide up and down is passed through the upper end of the frame 61. A spring is sleeved on the outer side of the screw rod 641. The spring and the screw rod 641 constitute the spring pressing module 64. The lower end of the screw rod is spirally fixed with the screw hole at the upper end of the sliding seat 631. The lower end of the spring abuts against the sliding seat 631. The upper end of the spring presses the upper inner wall of the slide groove 611. Then, under the elastic force of the spring, the sliding seat 631 moves downward to the lowest position under the limitation of the screw rod, thereby achieving the purpose of driving the driven roller 63 to clamp relative to the active roller 62. The screw rod can also be rotated to cooperate with the screw hole at the upper end of the sliding seat 631 to drive the sliding seat 631 to move upward, thereby achieving the purpose of lifting the driven roller 63 relative to the active roller 62.

[0027] A guide frame 7 is disposed on one side of the machine base 1 close to the unwinding device 4; a guide roller 71 is disposed at the end of the guide frame 7, and the guide roller 71 is provided for the film to pass around, thereby achieving the purpose of guiding the film and making the film transmission smoother.

[0028] The guide frame 7 is provided with at least one set of fifth sliding holes 72 and sixth sliding holes 73 distributed in the same straight line. A fifth limiting wheel 75 is installed on the fifth sliding hole 72, and a sixth limiting wheel 74 is installed on the fourth sliding hole 552. The interval between the fifth limiting wheel 75 and the sixth limiting wheel 74 is equivalent to the width of the diaphragm.

[0029] The assembly structures of the second, third, fourth, fifth and sixth limiting wheels are the same as the assembly structure of the first limiting wheel, and their functions are also the same, so they will not be described one by one here.

[0030] The guide frame 7 is fixed with an adsorption plate 76 having a plurality of third adsorption holes 761 . The bottom surface of the adsorption plate 76 is provided with a third negative pressure device corresponding to the third adsorption holes 761 . The membrane is adsorbed through the third adsorption holes 761 , thereby ensuring that the membrane is adhered to the adsorption plate 76 for transmission.

[0031] The winding device 3 and the unwinding device 4 have the same structure, and both include an air-inflating shaft 30 and a motor module 40 for driving the air-inflating shaft 30 to rotate.

[0032] To sum up, the utility model adopts the first adsorption hole 52 and the second adsorption hole 53 to adsorb and position the front and rear ends of the diaphragm passing through the punching position 20 in the punching device 2. The positioning is stable and reliable, which solves the technical problem that the prior art using a lifting cylinder and a clamping plate may not be able to stably press the diaphragm. At the same time, there is no need to adopt a relatively complex clamping structure composed of a lifting cylinder and a clamping plate. The utility model has a simpler structure and lower cost, and can also achieve stable and reliable positioning relative to the diaphragm, thereby ensuring the quality of subsequent punching, making the utility model extremely competitive in the market.
