[0022] By adopting the above technical scheme, the bidirectional screw rod 1 is rotated by motor, and under the limiting of guide rod 2, propelling seat 3 can drive the whole edge pressing mechanism 4 and anti-collision mechanism 5 to move and adjust the width distance of middle part, so that the whole device can be adaptively adjusted according to the width of corrugated board printing.
[0023] Further, the edge pressing mechanism 4 includes sleeve 401 fixedly installed on the lower surface of propelling seat 3, push spring 402 is fixedly arranged on the inner surface of sleeve 401, movable rod 403 is fixedly installed on the lower end of push spring 402, and movable rod 403 slides in the inner surface of sleeve 401;The edge pressing mechanism 4 further includes same connecting plate 404 fixedly arranged on the lower end of movable rod 403 on the front and back sides, and the lower surface of connecting plate 404 is evenly distributed with pressure roller 405 rotatably installed, and the lower surface of pressure roller 405 protrudes from connecting plate 404.
[0024] By adopting the above technical scheme, push spring 402 can drive movable rod 403 to stretch and retract in sleeve 401, to adjust the distance between connecting plate 404 and pressure roller 405 and the upper surface of printer conveying belt;
[0025] The self-stretching force of push spring 402 and the downward pushing force that is always kept are transmitted through movable rod 403, so that connecting plate 404 and pressure roller 405 can automatically adjust and adapt to corrugated board of different thicknesses for positioning;
[0026] Pressure roller 405 contacts corrugated paper first, so that when corrugated paper is positioned with edge pressing mechanism 4, the stress is rolling friction, which not only can reduce the conveying resistance, but also can avoid the surface friction damage of corrugated paper.
[0027] Further, the anti-collision mechanism 5 comprises side plates 501 fixedly installed on the left and right opposite sides of the outer surface of the connecting plate 404, and telescopic springs 502 fixedly installed on the inner surface of the side plates 501; the lower ends of the telescopic springs 502 are fixedly installed with moving plates 503, and the moving plates 503 slide on the inner surface of the side plates 501; the anti-collision mechanism 5 further comprises roller foot plates 504 fixedly installed on the opposite sides of the surface of the moving plates 503, and assembly plates 505 fixedly arranged on the ground opposite sides of the roller foot plates 504; the inner surface of the assembly plates 505 is fixedly installed with movable springs 506 on the upper and lower sides; the anti-collision mechanism 5 further comprises sliding blocks 507 fixedly installed on the opposite ends of the movable springs 506, and anti-collision rollers 508 rotatably installed on the middle of the upper and lower opposite sides of the sliding blocks 507; the ground opposite sides of the anti-collision rollers 508 protrude from the assembly plates 505.
[0028] By adopting the above technical scheme, when the compression roller 405 extrudes the surface of the corrugated paper, under the elastic force of the telescopic spring 502, the moving plate 503 and the roller foot plate 504 will continue to move downward by a distance, so that the roller foot plate 504 is attached to the surface of the printer conveying belt, and the rotating roller at the bottom of the roller foot plate 504 avoids the contact and wear of the plate body with the conveying belt, reducing the resistance; at this time, the assembly plate 505 is just located on the left and right sides of the corrugated board to limit the corrugated board, preventing the corrugated board from deviating;
[0029] When the corrugated board deviates, it will first contact the anti-collision roller 508, and since the anti-collision roller 508 can rotate by itself, the corrugated board will make the anti-collision roller 508 rotate for flexible contact, avoiding hard contact and friction, which not only can effectively and smoothly continue to convey forward, but also can avoid the wear and breakage of the edge position of the corrugated board;
[0030] When colliding with the anti-collision roller 508, the anti-collision roller 508 will be retracted into the assembly plate 505 through the sliding block 507, extruding the movable spring 506; by using the pushing force of the movable spring 506, the anti-collision roller 508 can be gradually pushed back in the subsequent process, so that the corrugated board is reset to the center, effectively preventing the corrugated board from deviating and colliding, ensuring the printing quality of the corrugated board, and using flexible limiting and anti-collision instead of hard limiting and blocking, which can greatly improve the integrity of the corrugated board itself.
[0031] Working principle: when using the corrugated board printing with adaptive edge pressing anti-collision device, first, the whole device is installed above the printer conveying belt, the corrugated board is conveyed by the conveying belt, according to the width of the corrugated board, the bidirectional screw 1 is driven to rotate by the motor, under the limiting of the guide rod 2, the advancing seat 3 can drive the whole pressing mechanism 4 and the anti-collision mechanism 5 to move and adjust the width distance of the middle part, then the self-expanding force of the thrust spring 402 and the downward pushing force are always kept, the pushing force is transmitted through the movable rod 403, which can make the connecting plate 404 and the pressing roller 405 automatically adjust and adapt to the different thickness of the corrugated board for positioning, at the same time, the pressing roller 405 preferentially contacts the corrugated paper, so that the corrugated paper and the pressing mechanism 4 are positioned by rolling friction, which not only can reduce the conveying resistance, but also can avoid the surface friction damage of the corrugated paper, when the pressing roller 405 extrudes the surface of the corrugated paper, under the elastic force of the extension spring 502, the movable plate 503 and the roller foot plate 504 will continue to move down a distance, so that the roller foot plate 504 is attached to the surface of the printer conveying belt, and the rotating roller avoids the plate body from contacting and wearing the conveying belt, which reduces the resistance, at this time, the assembly plate 505 is just located on the left and right sides of the corrugated board to limit the corrugated board, which can prevent the corrugated board from deviating, if the corrugated board deviates, it will preferentially contact the anti-collision roller 508, because the anti-collision roller 508 can rotate itself, the corrugated board will make the anti-collision roller 508 rotate, which can make flexible contact and avoid hard contact and friction, which can cause the edge position of the corrugated board to wear and break, when colliding with the anti-collision roller 508, the anti-collision roller 508 will shrink to the inside of the assembly plate 505 through the sliding block 507, which can extrude the movable spring 506, and the pushing force of the movable spring 506 can gradually push the anti-collision roller 508 back to its original position, so that the corrugated board is reset to the center, which can effectively prevent the corrugated board from deviating and colliding, this is the working principle of the corrugated board printing with adaptive edge pressing anti-collision device.
