Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Referring to fig. 1 and 2, a laser punching processing system for tipping paper includes a frame (not shown), a paper feeding mechanism 1 is disposed on the frame, a laser generating device 2 is disposed above the tipping paper, and includes a laser 21, a beam expander set 22, a shading device 23, a rotary prism 24, a reflecting mirror 25, N focusing mirrors 26 along a transmission light path of the laser generating device, and a focal point of laser emitted from the laser generating device falls on a movement path of the tipping paper, and further includes a first motor 3, a punching control device 5, a shading device motor 41, a rotary prism motor 42, and a punching control device 5, wherein the paper feeding mechanism 1 is connected with the first motor 3, and the first motor 3 is electrically connected with the punching control device 5; the shading device motor 41 and the rotary prism motor 42 are respectively electrically connected with the punching control device 5.

Referring to fig. 1, in some embodiments of the present invention, the paper feeding mechanism 1 includes a plurality of driving rollers 11, a plurality of driven rollers 12, a paper placing device 13, and a paper collecting device 14, wherein the plurality of driving rollers 11 and the plurality of driven rollers 12 are driven by the plurality of first motors 3 to drive the tipping paper to move along a fixed path. It is understood that the drive roller 11 or the driven roller 12 may also be referred to as a driving guide, a driven guide, or collectively as a guide. Specifically, the driven rollers 12 are driven by the two first motors 3 to drive the tipping paper to move at a constant speed along a fixed path.

In some embodiments of the present invention, the turning prism 24 has M faces, M is greater than or equal to 1. Furthermore, the N focusing mirrors 26 are not coplanar, and N is greater than or equal to 1. Specifically, the vertical planes of the N focusing mirrors 26 with respect to the movement direction of the tipping paper are not coplanar.

It will be appreciated that the shutter 23 is located in the exit path of the laser 21: specifically, the light shielding device 23 can shield the laser beam emitted by the laser 21 no matter the light shielding device is located on the incident light path or the emergent light path of the beam expander set 22, the rotary prism 24, the reflecting mirror 25 and the focusing mirror 26, so as to form spaced laser hole bands of the tipping paper.

Alternatively, the rotation speed of the shade motor 41 must be stable and adjustable, and may or may not be related to the rotation speed of the rotary prism motor 42.

Optionally, the rotating speed of the rotating prism motor 42 is stable and adjustable and has a function relation with the moving speed of the tipping paper, so that the pitch of each row of laser holes can be quantitatively and accurately adjusted.

Referring to fig. 3 and 4, specifically, the tipping paper is driven by the first motors 3 to move at a constant speed along the guide wheels at a certain speed, when the light blocking device motor 41 is stationary and light passes through, the laser beam continuously emitted by the laser 21 is expanded by the beam expanding lens group 22 (which may be composed of a front beam expanding lens and a rear beam expanding lens group), and is split and dispersed by the rotary prism 24, the continuous beam emitted by the laser 21 forms a parallel fan-shaped beam body with a certain thickness, and the beam body is reflected by a series of reflectors 25 onto n focusing and light receiving mirrors 26 which are uniformly arranged and are not coplanar on a vertical plane, so that the focused laser can shoot n laser holes which are not coplanar in front and rear on the moving tipping paper, when the rotary prism 24 is m-plane, each rotation of the prism disperses the continuous beam of the laser 21 into m fan-shaped bodies, and each front fan-shaped body shoots n front laser holes and n front laser holes in rear on the tipping paper, Then, the laser holes which are not coplanar rotate at a constant speed continuously by the rotating prism 24, and then n rows of laser holes which are uniformly arranged according to the set hole pitch are punched on the tipping paper.

In some embodiments of the present invention, the light shielding device 23 is a disk, and the disk is circumferentially provided with protruding teeth which are uniformly distributed. Specifically, when the motor 41 of the shading device is controlled to rotate, the uniformly protruding teeth on the shading disc can shade the n rows of holes on the tipping paper at certain time intervals, and the laser hole belts with the spaced tipping paper are obtained.
