Description

Technical Field

[0001] This invention relates to the field of packaging die-cutting technology, specifically to a die-cutting device for printing and packaging. Background Technology

[0002] Traditional die-cutting refers to a cutting process in the post-processing of printed materials. Die-cutting can cut printed materials or other paper products into a die-cutting plate according to a pre-designed pattern, so that the shape of the printed materials is no longer limited to straight edges and right angles. Traditional die-cutting production uses die-cutting blades to form a die-cutting plate according to the product design requirements. Under pressure, the printed materials or other plate-shaped blanks are cut into the required shape or creases. Creasing process uses crease cutters or crease dies to press creases into the plate under pressure, or uses rollers to roll creases into the plate so that the plate can be bent and shaped in a predetermined position. Usually, the die-cutting and creasing process combines the die-cutting blade and the crease cutter in the same template and performs die-cutting and creasing simultaneously on the die-cutting machine, which is simply called die-cutting.

[0003] Before die-cutting packaging cardboard, cardboard cut to a certain size needs to be prepared as die-cutting material. During the cutting process, some cardboard waste will be left on the surface of the cardboard. These wastes left on the surface of the cardboard can easily block the cutting head during die-cutting, causing unevenness in some parts of the cardboard surface and affecting the forming effect of the die-cut pattern. Therefore, a die-cutting device for printing and packaging is needed to clean the cardboard waste on the surface of the cardboard before die-cutting, so as to avoid the wastes blocking the cutting head and affecting the forming effect of the die-cut pattern.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This die-cutting device for printing and packaging, through the setting of a support and installation mechanism, a pushing mechanism, a pressing and anti-drop mechanism, a fixing mechanism, a waste cleaning mechanism, a front-end auxiliary feeding mechanism, a translation and locking mechanism, and a die-cutting mechanism, can push and fix the cardboard in real time through the pushing mechanism, the pressing and anti-drop mechanism, and the fixing mechanism. When the cardboard moves, the waste cleaning mechanism wipes and blows its surface, thereby cleaning the cardboard waste on the surface of the cardboard before die-cutting, avoiding the waste from blocking the cutter head and affecting the forming effect of the die-cutting pattern.

[0017] 2. The die-cutting device for printing and packaging is equipped with a pressure frame and overlapping blocks, so that after the device has finished working, the pressure frame can be unfolded to expose the conveyor belt and the carrier panel, making it convenient to clean the carrier panel.

[0018] 3.

This ensures that the cardboard can be smoothly conveyed laterally while forming a stable longitudinal clamping, avoiding the reverse thrust generated when the cleaning roller is wiping and the high pressure wind force generated by the dust removal fan blowing the cardboard off-center.

[0019] 4.

[0043] Working principle: During use, the drive motor 208, cleaning motor 503, and dust removal fan 507 are started. The electromagnetic lock 703 is energized to attract and fix the slider 702. Then, the cardboard is neatly placed on the exposed surface of the conveyor belt 204. The drive motor 208 drives the first active drive wheel 209 to rotate. The first active drive wheel 209 drives the first driven drive wheel 210 to rotate through the first drive belt 211, thereby driving the first drive shaft 202 to rotate. The first drive shaft 202 drives the conveyor wheel 207 to rotate, thereby driving the conveyor belt 204 to move. The conveyor belt 204 carries the cardboard forward towards the pressure rack 301. At this time, the cleaning motor 503 drives the cleaning shaft 504 to rotate. The cleaning shaft 504, through the drive gear 607 and... The driven gear 608 drives the gear column 601 to rotate through transmission and reversal. The gear column 601 drives the rotating shaft 602 to rotate through the second driving transmission wheel 604, the second driven transmission wheel 605, and the second transmission belt 606, thereby driving the feeding roller 603 to rotate. When the cardboard is pushed by the conveyor belt 204 to the bottom of the feeding roller 603, it is pushed into the interior of the pressure frame 301 by both the feeding roller 603 and the conveyor belt 204, and is inserted between each pressure roller 306 and the conveyor belt 204 in sequence. It is pressed and fixed downward by the pressure roller 306, and continues to be pushed forward by the conveyor belt 204. When the cardboard moves to the bottom of the cleaning roller 505, the cleaning shaft 504 rotates, driving the cleaning roller 505 to rotate. 5. The wiping sleeve 506 moves the wiping cardboard surface to clean the waste. As the cardboard continues to move below the dust removal fan 507, its surface is further cleaned by the high-speed airflow generated by the dust removal fan 507. At the same time, the cardboard continues to move forward. When the cardboard moves above the infrared detection unit 106, the infrared light emitted by the infrared emitter is blocked by the cardboard, forming diffuse reflection, which is received by the infrared receiver, thus forming a feedback signal. This causes the drive motor 208 to stop and the dual-output motor 807 to start. The dual-output motor 807 drives the eccentric wheel 808 to rotate one revolution. When the eccentric wheel 808 rotates, it pushes the lifting frame 802 to descend through the connecting rod 810, and then rises to form a die-cutting action. When the lifting frame 802 descends, it passes through the die-cutting blade 810. 05. The cardboard surface is pressed to form a die-cut pattern. The lifting frame 802 descends and then rises to form a die-cutting action, that is, the dual-output motor 807 rotates for one cycle. After the dual-output motor 807 rotates for one cycle, it stops. Then the infrared emitter is turned off, and the drive motor 208 is restarted. The conveyor belt 204 starts working again to drive the cardboard forward. After a period of time, the die-cut cardboard has passed the infrared detection unit 106. Then the infrared emitter is restarted. The die-cut cardboard continues to move forward until it is discharged. After the die-cutting work is completed, the electromagnetic lock 703 can be turned off, the support frame 801 above the pressure frame 301 can be slid off, and then the hook 401 can be unlocked to rotate and unfold the pressure frame 301, so as to facilitate the cleaning of the bottom of the pressure frame 301.
