Description

Technical Field

[0001] The utility model relates to the field of printed matter quality detection, in particular to a device for detecting the quality of self-adhesive printed matter. Background Art

[0002] Self-adhesive printing is generally done by applying a layer of self-adhesive on the back of the substrate and adhering it to an easily peelable release paper.

[0003] After printing, use a knife line to roll the print, peel off the blank excess part, and leave a certain shape of printed matter on the anti-stick paper. When using, peel off the finished product and stick it on the product or packaging.

[0004] The front of the substrate is generally printed with different shapes and patterns according to customer needs;

[0005] When producing self-adhesive printed products, it is generally necessary to use testing equipment to detect the printing quality of self-adhesive printed products. The traditional detection method is simply based on visual sensors to detect the printed pattern on the front of the substrate, and does not detect the release paper. The release paper is also part of the printed product. When the release paper is damaged, due to the obstruction of the substrate, when detecting the printed pattern on the front of the substrate, it cannot detect whether the release paper is damaged, which is prone to missed detection.

[0061] Two groups of stacking positions 2 are designed and symmetrically arranged on both sides of the conveyor belt 12, which are used to classify and stack the printed products after inspection according to the inspection results.

[0062] The utility model turns over the printed matter by designing a turning mechanism, thereby completing the inspection of both sides of the printed matter, and can not only determine whether the pattern printing on the front substrate of the printed matter is complete, but also detect whether the anti-sticking paper is damaged. Compared with the traditional single-sided inspection, it avoids the phenomenon of missed inspection. At the same time, the stacking position 2 is designed to stack the printed matter after inspection, so that the printed matter that passes the inspection can be directly packed without the need to align and stack again.

[0063] A transport support 11 is provided below the conveyor belt 12 .

[0064] The stacking position 2 includes:

[0065] A table 211 is provided on the side of the conveyor belt 12;

[0066] The suction mechanism 21 is provided on the table 211;

[0067] A limiting mechanism 22 connected to the table 211;

[0068] The lifting mechanism 23 is connected to the table 211 .

[0069] The suction mechanism 21 includes:

[0070] A suction rack 212 is installed on the table 211;

[0071] A lifting cylinder 213 is connected to the suction frame 212;

[0072] The rotating cylinder 214 is connected to the output end of the lifting cylinder 213;

[0073] The suction cup frame 215 is connected to the output end of the rotating cylinder 214;

[0074] The stacking suction cups 216 are designed in plurality and connected to the suction cup frame 215 .

[0075] The limiting mechanism 22 includes two groups of limiting units placed in a cross shape, and each group of limiting units includes:

[0076] A limiting motor 221 is connected to the table 211;

[0077] There are two sets of limiting drive wheels, one set is connected to the output end of the limiting motor 221, and the other set is arranged below the table 211;

[0078] The limiting belt 222 is mounted on two sets of limiting drive wheels;

[0079] The limiting frames 223 are designed in two groups, one group is connected to one side of the limiting belt 222, and the other group is connected to the other side of the limiting belt 222. Each group of limiting frames 223 is also provided with a limiting slider, and the bottom of the table 211 is installed with a limiting slide rail 224 adapted to the limiting slider.

[0080] The lifting mechanism 23 includes:

[0083] The lifting guide rod 233 is connected to the lifting frame 232 . A sliding sleeve is sleeved on the lifting guide rod 233 , and the sliding sleeve is embedded in the table top 211 .

[0084] Working principle: The self-adhesive printed matter is transported by the conveyor belt 12. When the self-adhesive printed matter moves, the detection sensor first detects one side of the self-adhesive printed matter, and then the flipping motor drives the flipping output shaft 15 to rotate, drives the flipping input shaft 16 to rotate, drives the flipping frame 17 to move, drives the flipping suction cup 18 to suck the self-adhesive printed matter and completes the flipping work. At this time, the detection sensor detects the other side of the self-adhesive printed matter. After the detection is completed, the qualified products are stacked at the stacking position 2 on one side, and the unqualified products are stacked at the stacking position 2 on the other side.

[0085] During palletizing, the lifting frame 232 is lifted to an appropriate position by the lifting cylinder 231, and then the limiting motor 221 drives the limiting belt 222 to move, driving the limiting frame 223 to slide along the limiting slide rail 224, so that multiple limiting frames 223 form a fence;

[0086] Then, the suction cup frame 215 is driven to rotate by the rotating cylinder 214, which drives the stacking suction cup 216 to rotate. The lifting cylinder 213 then drives the rotating cylinder 214 to rise and fall, which drives the suction cup frame 215 to rise and fall, and drives the stacking suction cup 216 to absorb the self-adhesive printed matter on the flipping suction cup 18 (the flipping suction cup 18 stops sucking at this time), and moves the self-adhesive printed matter to the fence formed by multiple limit stands 223. The stacking suction cup 216 relaxes the suction work and drops the self-adhesive printed matter onto the lifting frame 232. As the number of self-adhesive printed matters gradually increases, the lifting cylinder 231 drives the lifting frame 232 to gradually descend, completing the stacking.

However, the present invention is not limited to the specific details in the above embodiments.
