Embodiment one of the roll-to-roll laser die cutting machine of the application:
as shown in fig. 1 to 7, the roll-to-roll laser die-cutting machine comprises a frame 500, and a feeding film-covering module 100, a laser die-cutting module 200 and a slitting waste-discharging module 300 which are positioned on the frame 500. The material to be die-cut 400 is die-cut by the feeding film-covering module 100 and the laser die-cutting module 200 in sequence to form the material to be discharged 450.
The slitting and discharging module 300 includes a separating roller 440 and a waste collecting roller 430 which are disposed in parallel, a guide roller is disposed between the separating roller 440 and the waste collecting roller 430, and the material 450 to be discharged is separated into a finished product 410 and a waste 420 by the separating roller 440. The reject 420 comprises a web formed by a longitudinal reject bar 421 and a transverse reject bar 422, which after separation is rotated about the centre of a separation roller 440 and then wound up on a reject collection roller 430 via a guide roller. The finished product 410 includes a base film 411 and a finished product sheet of material 412 on the base film 411, with the finished product 410 passing through a separator roll 440 at a tangential angle and then being wound onto a subsequent finished product take-up roll. The angle between the finished product 410 passing through the separating roller 440 and the winding direction of the reject 420 is an obtuse angle.
The separation roller 440 includes a fixed shaft 441 fixed to the frame 500, and a rotatable drum is fitted around the fixed shaft 441, and is mounted on the fixed shaft 441 through a bearing 444. The roller comprises arc-shaped lugs 443 and arc-shaped grooves 442 which are distributed in sequence in the circumferential direction and are staggered in height. The central axes of the arcuate tab 443 and the arcuate slot 442 coincide and the radius of the arcuate tab 443 is greater than the radius of the arcuate slot 442. The roller is provided with a telescopic slot hole 447 which penetrates through the inside and the outside at a position between the arc-shaped lug 443 and the arc-shaped slot 442, a telescopic jacking block 445 which can stretch out and draw back inside and outside is arranged in the telescopic slot hole 447 in a guiding way, the telescopic slot hole 447 is positioned between the arc-shaped lug 443 and the arc-shaped slot 442, the fixed shaft 441 comprises a base shaft part 446 which protrudes towards one side, the distance between the outer peripheral surface of the convex shaft part 446 and the rotation center of the fixed shaft 441 is larger than the radius of the base shaft part of the fixed shaft 441, the outer peripheral surface of the convex shaft part 446 is attached to the inner wall of the roller, the radius of the base shaft part of the fixed shaft 441 is smaller than the inner diameter of the roller, and the roller rotates around the center of the base shaft part. In the process of rotating the roller, at the separation position of the finished product 410 and the waste product 420, the inner end of the telescopic jacking block 445 rotates to the convex shaft portion 446, the convex shaft portion 446 ejects the telescopic jacking block 445 outwards, the outer end of the telescopic jacking block 445 and the arc-shaped lug 443 form a jacking boss with the same radius, and the size of the outer peripheral surface of the jacking boss is consistent with that of the finished product material piece 412. After separation, the roller rotates until the base shaft portion of the fixed shaft 441 corresponds to the telescopic slot 447, and the telescopic jack 445 is retracted into the telescopic slot 447. In other embodiments, a return spring may be provided on the roller to retract the telescoping roof blocks 445 into the telescoping slots 447, and an anti-slip structure may be provided between the roller and the telescoping roof blocks 445.
The specific number of out-of-roll Zhou Huxing lugs 443 is a combination of the specifications of the roll and stationary shaft 441 of the separator roll 440 and the dimensions of the finished sheet 412. In this embodiment, the separating roller 440 is circumferentially provided with two symmetrical arc-shaped protrusions 443 and two arc-shaped grooves 442, and four telescopic slotted holes 447 and telescopic jacking blocks 445, and the convex shaft portion 446 simultaneously jacks two telescopic jacking blocks 445 on both sides of the same arc-shaped groove 442 each time. The separating roller 440 is also axially provided with two arcuate projections 443 so that the separating roller 440 rotates one revolution to separate four finished material sheets 412.
In this embodiment, in the axial direction of the separation roller 440, the arc-shaped groove 442 on the surface of the roller has a structure with a middle portion higher and two ends lower, and specifically, the groove bottom of the arc-shaped groove 442 is sequentially reduced with the middle position of the separation roller 440 as the radius of the symmetrical surface facing to two sides.
The working process is as follows:
after the material to be die-cut 400 passes through the feeding film-covering module 100 and the laser die-cutting module 200 in sequence, a material to be discharged 450 is formed. The waste material 450 to be discharged passes below the separating roller 440, the waste 420 upwards winds around the separating roller 440 and synchronously rotates with the roller, the separating position is the last connecting position of the arc-shaped convex block 443 and the finished product 410 through the arrangement of the height dislocation of the arc-shaped groove 442 and the arc-shaped convex block 443, the finished product 410 is always pressed to the top in the separating process, the edge of the finished product material piece 412 is prevented from being lifted, and the quality of the finished product is ensured. After the waste 420 is separated from the finished product 410, the waste 420 is separated from the separation roller 440.
The telescoping jack 445 will not move away from the male shaft 446 and retract until the waste 420 and the separator roller 440 separate, after the finished product 410 and the waste 420 separate, preventing the waste 420 from deforming or tearing due to the clamping of the arcuate slot 442 to the transverse strip 422 of waste, and making the overall waste discharge process more stable.
In the separation process of the finished product 410 and the waste product 420, due to the convex arrangement of the arc grooves 442, the waste product 420 is prevented from being deformed due to synchronous separation in the order of two ends before the middle, and the problem that the winding length is reduced and the winding quality is reduced due to the fact that the winding of the waste collecting roller 430 is not standardized is solved.
In other embodiments of the roll-to-roll laser die cutting machine of the present application, the differences from the above-described embodiments are: the telescoping roof block 445, telescoping slot 447 and male shaft 446 are omitted so that the arcuate tab 443 is of the same size as the finished sheet 412 and bears against the finished sheet 412.
The specific structure and working principle of the feeding film-covering module 100 and the laser die-cutting module 200 in the present application are all the prior art, and are not described herein.
The above examples only show a few specific embodiments of the present application, and the description thereof is more specific and detailed, and for brevity, all of the possible combinations of the features of the above examples are not described, but rather should not be construed as limiting the scope of the application. It should be noted that, for a person skilled in the art, it is possible to make several variations and modifications without departing from the spirit of the present application, as long as there are no contradictions between the combinations of these technical features, which should be considered as the scope of the present description. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
