[0026] Reference Figures 1 to 3 and Figure 9As shown, this utility model provides a technical solution: an electrostatic drilling machine, including a frame 10, an electrostatic drilling device 20, and a winding / unwinding mechanism 30; the electrostatic drilling device 20 includes a discharge ceramic rod mechanism 21, a first edge distance adjustment component 22, and a second edge distance adjustment component 23. The discharge ceramic rod mechanism 21 includes opposing first discharge ceramic rod assemblies 211 and second discharge ceramic rod assemblies 212. The first discharge ceramic rod assembly 211 is connected to the frame 10 through at least two first edge distance adjustment components 22, and the second discharge ceramic rod assembly 212 is connected to the frame 10 through at least two second edge distance adjustment components 23. The distance adjustment component 23 is connected to the frame 10. The first distance adjustment component 22 and the second distance adjustment component 23 each include a support 221 and a linear module 222. The support 221 is connected to the frame 10, and the linear module 222 is installed on the frame 10. The output end of the linear module 222 of the first distance adjustment component 22 is connected to the first discharge ceramic rod assembly 211, and the output end of the linear module 222 of the second distance adjustment component 23 is connected to the second discharge ceramic rod assembly 212. The winding and unwinding mechanism 30 is provided on the frame 10 and is arranged opposite to the electrostatic punching device 20.

[0027] For example, the voltage of the first discharge ceramic rod assembly 211 can be positive, and the voltage of the second discharge ceramic rod assembly 212 can be negative.

[0028] In this embodiment, since both ends of a single discharge ceramic rod assembly are equipped with edge adjustment components, during hole spacing adjustment, one edge adjustment component provides driving force to adjust the distance between the first set of discharge pins near the end of the discharge ceramic rod assembly and the frame 10, thereby adjusting the edge spacing between the discharge ceramic rod assembly and the bonding paper, and thus changing the initial drilling position. During hole width adjustment, the other edge adjustment component provides driving force to adjust the distance between the last set of discharge pins at the far end of the discharge ceramic rod assembly and the frame 10, thereby causing the entire discharge ceramic rod assembly to form a certain tilt angle with the frame, creating the hole width. Thus, by adjusting the hole spacing, the requirements of different bonding papers for hole spacing are met; by adjusting the hole width, the requirements of different bonding papers for the hole width are adapted.

[0029] Reference Figures 1 to 3As shown, in some embodiments, the discharge ceramic rod mechanism 21 is at least one pair, and each pair of discharge ceramic rod mechanisms 21 is divided into a first discharge ceramic rod mechanism 21 and a second discharge ceramic rod mechanism 21. The support 221 of the second edge adjustment component 23 of the first discharge ceramic rod mechanism 21 and the support 221 of the first edge adjustment component 22 of the second discharge ceramic rod mechanism 21 are both connected to the frame 10 through the first sliding member 2211. The electrostatic drilling device 20 includes a third edge adjustment component 24, and the number of third edge adjustment components 24 is related to the number of second edge adjustment components 23 of the first discharge ceramic rod mechanism 21. The third edge adjustment component 24 corresponds one-to-one with the second edge adjustment component 23 of the first discharge ceramic rod mechanism 21. The third edge adjustment component 24 includes a first connecting plate 241 and a first linear drive component 242. The first connecting plates 241 are a pair. One first connecting plate 241 is disposed on the support 221 of the second edge adjustment component 23 of the first discharge ceramic rod mechanism 21, and the other first connecting plate 241 is disposed on the support 221 of the first edge adjustment component 22 of the first discharge ceramic rod mechanism 21. The output end and the fixed end of the first linear drive component 242 are connected one-to-one to the pair of first connecting plates 241.

[0030] For example, the first linear drive 242 can be a cylinder, a hydraulic cylinder, or an electric actuator, etc.

[0031] In this embodiment, the third margin adjustment component 24 provides driving force, which can drive the second margin adjustment component 23 of the first discharge ceramic rod mechanism 21 to move toward or away from the first margin adjustment component 22 of the first discharge ceramic rod mechanism 21, and the first margin adjustment component 22 of the second discharge ceramic rod mechanism 21 to move toward or away from the second margin adjustment component 23 of the second discharge ceramic rod mechanism 21, thereby adjusting the spacing between the electrostatic perforations on the splicing paper. When the third margin adjustment component 24 is working, the first linear drive component 242 pushes a pair of first connecting plates 241, causing the supports 221 of the second margin adjustment component 23 of the first discharge ceramic rod mechanism 21 and the supports 221 of the first margin adjustment component 22 of the second discharge ceramic rod mechanism 21 to move synchronously through the first sliding component 2211. For each discharge ceramic rod mechanism 21, by adjusting the spacing between the first discharge ceramic rod component 211 and the second discharge ceramic rod component 212, the width of the paper feeding channel can be increased, facilitating the paper feeding operation by the operator.

[0032] Reference Figure 1 and Figure 4 As shown, in some embodiments, the electrostatic punching machine includes an air permeability testing mechanism 40, which is located between the electrostatic punching device 20 and the winding and unwinding mechanism 30. The air permeability testing mechanism 40 includes a camera assembly 41, which is mounted on the frame 10.

[0033] For example, camera assembly 41 may include a housing and at least one camera, wherein the at least one camera is disposed within the housing.

[0034] In this embodiment, the camera assembly 41 captures images of the holes in the splicing paper and transmits the images to the computer's image processing system, which then calculates the hole density and distribution uniformity to determine whether the air permeability meets the standard.

[0039] For example, the second linear drive 552 can be a cylinder, a hydraulic cylinder, or an electric actuator, etc.

[0040] In this embodiment, the feed paper has a waste paper segment, which needs to be cut off when the take-up and unwinding mechanism 30 winds it up. Before cutting, the starting end of the waste paper segment passes through the pressure space between the pressure roller seat 542 and the pressure roller 543, and the waste paper segment is wound around the bottom paper roller 53. As the take-up and unwinding mechanism 30 starts its take-up and unwinding operation, when the ending end of the waste paper segment corresponds to the cutter 553, the second linear drive member 552 drives the cutter 553 to cut off the waste paper segment, so that the starting end of the perforated segment of the feed paper can be wound around the take-up roller of the take-up and unwinding mechanism 30.

[0044] In this embodiment, the protective sleeve protects the cutter 553 and ensures the service life of the cutter 553.

[0045] Reference Figure 7 As shown, in some embodiments, the cutter assembly 55 includes a plurality of air nozzles, all of which are located on the side of the base 551 facing the take-up and unwinding mechanism 30.

[0046] In this embodiment, air supplied by an external pipeline is introduced through an air nozzle to blow away debris during the cutting of waste paper segments, thus preventing blockage of the cutter 553.

[0048] For example, the third linear drive 56 can be a cylinder, a hydraulic cylinder, or an electric actuator, etc.

[0049] In this embodiment, after the winding and unwinding are completed, the third linear drive 56 drives the base plate 51 to move away from the winding and unwinding mechanism 30 through the second sliding member 511, so that the zero-meter mechanism 50 is moved away from the winding and unwinding mechanism 30 as a whole, so as to facilitate the removal of the finished splicing paper roll.
