[0002] Digital anti-counterfeiting printing is a technology that prints digital codes on product packaging or labels in a specific way. Consumers can enter the digital code on the product by making a phone call, sending text messages or logging on to a website. The system will automatically compare the data with the central database to verify the authenticity of the product.

[0003] The utility model patent with announcement number CN214324622U discloses a printer for invisible inkjet anti-counterfeiting printing, including a base and an inkjet printing mechanism. A support frame is fixedly provided on the surface of the base, and the inkjet printing mechanism is fixedly installed on the top of the support frame. A conveyor frame is horizontally arranged on the upper surface of the base and below the inkjet printing mechanism. A conveyor belt is arranged inside the conveyor frame, and two baffles arranged in an "eight" shape are arranged above the conveyor belt. A rotating shaft is rotatably arranged at the upper left ends of the two baffles through a first rolling bearing, and the upper ends of the two rotating shafts are fixedly connected to the top of the support frame. Moving rods are slidably arranged at the upper right ends of the two baffles, and a fixed plate is longitudinally fixed on the top of the support frame and above the two moving rods. A strip groove is opened on the lower surface of the fixed plate. The utility model can accurately print anti-counterfeiting labels on packaging boxes, thereby improving the efficiency of anti-counterfeiting printing.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The anti-counterfeiting printing work is carried out by placing the packaging box on a conveyor belt and then driving the packaging box to move under the inkjet printing mechanism. The printed packaging box will be moved with the conveyor belt to the receiving box for unified collection. However, when the anti-counterfeiting label is just printed on the surface of the packaging box, the ink on its surface may not have dried yet. After multiple packaging boxes fall into the receiving box, friction and collision will occur between the multiple packaging boxes, which may cause the ink layer to fall off or become blurred, thereby affecting the anti-counterfeiting effect. In addition, when the personnel take the packaging box out of the receiving box, the anti-counterfeiting label may be accidentally touched by the hand, causing the anti-counterfeiting label to become blurred.

[0018] A method for using a digital anti-counterfeiting printing device comprises the following specific steps:

[0019] S1. Place the packaging box to be printed with anti-counterfeiting labels on the conveyor belt. The packaging box moves with the conveyor belt. When the packaging box moves to the bottom of the inkjet printing mechanism, the electric push rods on both sides drive the clamping plates on both sides to move simultaneously and approach each other. When the clamping plates fit the end faces of the packaging box, the packaging box is straightened and the anti-counterfeiting labels are printed on the packaging box by the inkjet printing mechanism.

[0020] S2. After the anti-counterfeiting label is printed on the surface of the packaging box, the clamp releases the packaging box, and the packaging box continues to be transported to the left. When the packaging box is under the fixed plate, according to the size and position of the anti-counterfeiting label, multiple baffles 1 are driven to move radially at the same time, and baffles 2 and baffles 3 slide relative to each other, so that a baffle is formed under the action of baffles 1, 2, and 3, and the bottoms of baffles 1, 2, and 3 are in contact with the upper surface of the packaging box. At this time, the anti-counterfeiting label is covered, and then the hot air blower is started, and the hot air enters the enclosure through the air outlet pipe to dry the ink;

[0021] S3. After the anti-counterfeiting label of the packaging box is dried, the packaging box continues to be conveyed to the left. When the packaging box moves to the blanking plate, the packaging box slides to the top of the adjustment table along with the blanking plate, and multiple push blocks slide toward the center of the adjustment table at the same time until the multiple push blocks fit the four sides of the packaging box. Then, according to the side length of the packaging box, multiple limit frames slide on the limit rods, and the inner angle of the limit frame is regarded as a corner of the square, so that the area of ​​the square formed by the angles of the multiple limit frames is adjusted to be the same as the area of ​​the packaging box. At this time, the four corners of the packaging box are just aligned with the four corners of the limit frame;

[0022] S4. Make the suction cup contact with the bottom of the packaging box, and then use the suction cup to absorb the bottom of the packaging box to drive the packaging box to rise. When the four corners of the packaging box contact the inclined surface at the bottom of the support block, the support block can be squeezed into the inner cavity of the sliding sleeve, and the spring is compressed. When the lower end surface of the packaging box is higher than the upper end surface of the support block, the support block is reset under the action of the spring, and the support block can be used to support the packaging box. At this time, the placement of a packaging box can be completed, and whenever a packaging box is about to be placed on the support block at the bottom of the limit frame, the lifting plate is moved horizontally so that the upper end surface of the lifting block is fitted with the bottom of the packaging box, and then the slide plate is slid upward to make the lifting block drive the placed packaging box to move upward, and the packaging box is moved upward by squeezing the support block again. One layer can be provided for the packaging box at the bottom, and the above operation can be repeated to stack multiple packaging boxes.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The digital anti-counterfeiting printing device and the method of use described in the present invention place the packaging box to be anti-counterfeiting printed on the top of the conveyor belt, and the packaging box moves with the conveyor belt. When the packaging box moves to the bottom of the inkjet printing mechanism, the electric push rods on both sides are started to drive the clamping plates on both sides to move simultaneously and approach each other. When the clamping plates are in contact with the end faces of the packaging box, the packaging box is straightened, and then the inkjet printing mechanism is used to print the anti-counterfeiting label on the packaging box, thereby ensuring the accuracy of printing.

[0025] 2. The digital anti-counterfeiting printing equipment and the method of use described in the present invention utilize an ink protection stacking mechanism to dry the ink after the anti-counterfeiting label is printed on the packaging box, thereby preventing the ink layer from falling off when the anti-counterfeiting label is accidentally touched by the hands of subsequent personnel. In addition, by first covering the anti-counterfeiting label and then drying it, the hot air is more concentrated. Since the entire enclosure area is adjustable, it can adapt to anti-counterfeiting labels of different sizes, and to a large extent reduces the area where the hot air is blown to areas other than the anti-counterfeiting label, thereby increasing the drying speed, shortening the drying time, and preventing the packaging box from being damaged by heat due to long-term drying of the ink. In addition, for the dried packaging boxes, multiple packaging boxes can be neatly stacked to ensure the neatness of the packaging boxes, which is convenient for the subsequent collection and transportation of the packaging boxes. In addition, since the multiple packaging boxes are separated from each other and do not fit together, the anti-counterfeiting label ink layer falls off and becomes blurred due to mutual squeezing and friction between the packaging boxes, thereby further protecting the printing quality of the anti-counterfeiting label.

[0052] Specifically, digital anti-counterfeiting printing is a technology that prints digital codes on product packaging or labels in a specific way. Consumers can input the digital codes on the products by making a phone call, sending text messages or logging on to a website, and the system will automatically compare the digital codes with the data in the central database to verify the authenticity of the products. When the existing anti-counterfeiting printing equipment is in use, the packaging box is placed on a conveyor belt 6, and then the packaging box is driven to move under the inkjet printing mechanism 3 to perform anti-counterfeiting printing. The printed packaging box will be moved with the conveyor belt 6 to the receiving box for unified collection. However, when the anti-counterfeiting label is just printed on the surface of the packaging box, the ink on its surface may not be dry yet. After multiple packaging boxes fall into the receiving box, friction and collision will occur between the multiple packaging boxes, which may cause the ink layer to fall off or become blurred, thereby affecting the anti-counterfeiting effect. In addition, when the personnel take the packaging box out of the receiving box, the anti-counterfeiting label may be accidentally touched by the hand, causing the anti-counterfeiting label to become blurred.

[0053] Therefore, in order to solve the above-mentioned problem, this embodiment is used for square packaging boxes of the same specifications. After the anti-counterfeiting label is printed on the surface of the packaging box, the clamping plate 5 loosens the packaging box, and the packaging box continues to be conveyed to the left. When the packaging box is under the fixed plate 37, according to the size and position of the anti-counterfeiting label, the motor 4 32 and the motor 5 48 are started respectively. The motor 4 32 drives the threaded rod 4 31 to rotate, so that the fixed plate 37 moves back and forth. The motor 5 48 drives the gear 1 45 to rotate, so that multiple gears 2 46 and connecting rod 2 47 can rotate at the same time. When the angle between the connecting rod 2 47 and the connecting rod 3 49 changes, multiple baffles 1 41 can be moved radially at the same time, and the baffles 2 42 and the baffles 3 43 can slide relative to each other, so that an enclosure can be formed under the action of the baffles 1 41, the baffles 2 42 and the baffles 3 43, and the area of ​​this enclosure is taken as Depending on the size of the anti-counterfeiting label, baffle plate 1 41, baffle plate 2 42, baffle plate 3 43 are made to minimize the area of ​​the entire enclosure as much as possible without contacting the anti-counterfeiting label, and the bottom of baffle plate 1 41, baffle plate 2 42, baffle plate 3 43 is made to contact the upper surface of the packaging box under the action of electric push rod 34. At this time, the anti-counterfeiting label is covered, and then the hot air blower 38 is started, and the hot air enters the enclosure through the air outlet 39 to dry the ink. Thus, by first covering the anti-counterfeiting label and then drying it, the hot air is more concentrated. Since the area of ​​the entire enclosure is adjustable, it can adapt to anti-counterfeiting labels of different sizes, greatly reducing the range of hot air blowing to other than the anti-counterfeiting label, improving the drying speed, shortening the drying time, avoiding the situation that the packaging box is damaged by heat due to long-term drying of the ink, and avoiding the situation that the ink layer falls off when the subsequent personnel touch the anti-counterfeiting label by mistake.

[0054] Although the ink layer can be dried to a large extent by drying to avoid the risk of ink layer falling off due to accidental touch by people's hands, since the newly dried ink layer may not be completely firm, if multiple packaging boxes rub and collide with each other at this time, and the force is too great, the ink layer of the anti-counterfeiting label may still fall off and become blurred. Therefore, after the anti-counterfeiting label of the packaging box is dried, the packaging box continues to be conveyed to the left, and when the packaging box moves to the blanking plate 14, the packaging box slides to the top of the adjustment table 12 with the blanking plate 14, and then the multiple electric push rods 15 are started at the same time, and the multiple push blocks 50 slide toward the center of the adjustment table 12 at the same time until the multiple push blocks 50 are in contact with the four sides of the packaging box, and then Then, according to the side length of the packaging box, the motor 13 is started to drive the threaded rod 3 28 to rotate, so that the threaded block 29 is lifted and lowered and drives multiple connecting rods 1 30 to rotate at the same time, so that the limiting frame 17 slides on the limiting rod 27, and the angle inside the limiting frame 17 is regarded as a corner of the square, so that the area of ​​the square composed of the angles of multiple limiting frames 17 is adjusted to be the same as the area of ​​the packaging box. At this time, the four corners of the packaging box are just aligned with the four corners of the limiting frame 17, and then the electric push rod 2 15 is started to drive the lifting plate 16 to rise, so that the hard tube 51 passes through the through hole of the adjustment table 12, and the suction cup 52 contacts the bottom of the packaging box, and then the air pump 11 is used to evacuate the suction cup 52 to adsorb the bottom of the packaging box, and then multiple push rods are used. The moving block 50 releases the packaging box, and the electric push rod 2 15 continues to drive the packaging box to rise. When the four corners of the packaging box contact the inclined surface at the bottom of the support block 54, the support block 54 can be squeezed into the inner cavity of the sliding sleeve 18, and the spring 55 is compressed until the end surface of one side of the support block 54 is flush with the inner end surface of the limiting frame 17. When the lower end surface of the packaging box is higher than the upper end surface of the support block 54, the support block 54 is reset under the action of the spring 55, and the support block 54 can be used to support the packaging box. At this time, the placement of a packaging box can be completed, and then the above operation can be repeated to lift the subsequent packaging boxes upward, and whenever a packaging box is about to be placed on the support block 54 at the bottom of the limiting frame 17, the motor 3 23 drives the screw The second threaded rod 26 rotates to make the lifting plate 19 move horizontally, so that the upper end surface of the lifting block 20 fits with the bottom of the packaging box, and then the second motor 21 drives the threaded rod 1 22 to rotate, so that the slide plate 24 slides upward, so that the lifting block 20 drives the placed packaging box to move upward, and again by squeezing the support block 54, the packaging box moves up one layer, so as to provide a placement space for the packaging box at the bottom layer, and repeating the above operation can make multiple packaging boxes stacked, and ensure the neatness of the packaging boxes, which is convenient for the subsequent collection and transportation of the packaging boxes. In addition, since the packaging boxes do not fit each other, it also avoids the situation that the anti-counterfeiting ink layer falls off and becomes blurred due to the mutual squeezing and friction of the packaging boxes.

[0055] Therefore, by utilizing the ink protection stacking mechanism, the ink can be dried after the anti-counterfeiting label is printed on the packaging box, thereby preventing the ink layer from falling off when the subsequent personnel accidentally touch the anti-counterfeiting label with their hands. In addition, by first covering the anti-counterfeiting label and then drying it, the hot air is more concentrated. Since the entire enclosure area is adjustable, it can adapt to anti-counterfeiting labels of different sizes, which greatly reduces the range of hot air blowing to other than the anti-counterfeiting label, improves the drying speed, shortens the drying time, and avoids the situation where the packaging box is damaged by heat due to long-term ink drying. In addition, for the dried packaging boxes, multiple packaging boxes can be neatly stacked to ensure the neatness of the packaging boxes, which is convenient for the subsequent collection and transportation of the packaging boxes. In addition, since the multiple packaging boxes are separated from each other and do not fit together, it is also avoided that the ink layer of the anti-counterfeiting label falls off and becomes blurred due to the mutual squeezing and friction of the packaging boxes, thereby further protecting the printing quality of the anti-counterfeiting label.

[0056] A method for using a digital anti-counterfeiting printing device comprises the following specific steps:

[0057] S1. Place the packaging box to be printed with anti-counterfeiting labels on the conveyor belt 6. The packaging box moves with the conveyor belt 6. When the packaging box moves to the bottom of the inkjet printing mechanism 3, the electric push rods 4 on both sides drive the clamping plates 5 on both sides to move simultaneously and approach each other. When the clamping plates 5 are in contact with the end faces of the packaging box, the packaging box is straightened, and the inkjet printing mechanism 3 is used to print the anti-counterfeiting labels on the packaging box.

[0058] S2. After the anti-counterfeiting label is printed on the surface of the packaging box, the clamping plate 5 releases the packaging box, and the packaging box continues to be transported to the left. When the packaging box is under the fixed plate 37, according to the size and position of the anti-counterfeiting label, multiple baffles 1 41 are driven to move radially at the same time, and baffles 2 42 and baffles 3 43 slide relative to each other, so that a baffle 1 41, baffle 2 42, and baffle 3 43 are formed under the action of baffles 1 41, baffle 2 42, and baffle 3 43, and the bottoms of baffles 1 41, baffle 2 42, and baffle 3 43 are in contact with the upper surface of the packaging box. At this time, the anti-counterfeiting label is covered, and then the hot air blower 38 is started, and the hot air enters the enclosure through the air outlet pipe 39 to dry the ink;

[0059] S3, after the anti-counterfeiting label of the packaging box is dried, the packaging box continues to be conveyed to the left. When the packaging box moves to the blanking plate 14, the packaging box slides to the top of the adjustment table 12 along with the blanking plate 14, and multiple push blocks 50 slide toward the center of the adjustment table 12 at the same time until the multiple push blocks 50 are in contact with the four sides of the packaging box. Then, according to the side length of the packaging box, multiple limit frames 17 are slid on the limit rod 27, and the inner angle of the limit frame 17 is regarded as a corner of a square, so that the area of ​​the square formed by the angles of the multiple limit frames 17 is adjusted to be the same as the area of ​​the packaging box. At this time, the four corners of the packaging box are just aligned with the four corners of the limit frame 17;

[0060] S4, make the suction cup 52 contact with the bottom of the packaging box, and then use the suction cup 52 to absorb the bottom of the packaging box to drive the packaging box to rise. When the four corners of the packaging box contact the inclined surface at the bottom of the support block 54, the support block 54 can be squeezed toward the inner cavity of the sliding sleeve 18, and the spring 55 is compressed. When the lower end surface of the packaging box is higher than the upper end surface of the support block 54, the support block 54 is reset under the action of the spring 55, and the support block 54 can be used to support the packaging box. At this time, the placement of a packaging box can be completed, and whenever a packaging box is about to be placed on the support block 54 at the bottom of the limit frame 17, the lifting plate 19 is moved horizontally to make the upper end surface of the lifting block 20 fit the bottom of the packaging box, and then the slide plate 24 is slid upward to make the lifting block 20 drive the already placed packaging box to move upward, and again by squeezing the support block 54, the packaging box is moved upward by one layer, which can provide a placement space for the packaging box at the bottom layer. Repeat the above operation to stack multiple packaging boxes.

[0061] Working principle: Place the packaging box to be anti-counterfeiting printed on the conveyor belt 6, and the packaging box moves with the conveyor belt 6. When the packaging box moves to the bottom of the inkjet printing mechanism 3, the electric push rods 1 4 on both sides drive the clamps 5 on both sides to move simultaneously and approach each other. When the clamps 5 fit the end faces of the packaging box, the packaging box is straightened, and the inkjet printing mechanism 3 is used to print the anti-counterfeiting label on the packaging box; after the anti-counterfeiting label is printed on the surface of the packaging box, the clamps 5 release the packaging box, and the packaging box continues to be conveyed to the left. When the packaging box is under the fixed plate 37, according to the size and position of the anti-counterfeiting label, multiple baffles 1 41 are driven to move radially at the same time, and baffles 2 42 and baffles 43 are moved radially. When the three baffles 43 slide relative to each other, a baffle can be formed under the action of baffle one 41, baffle two 42, and baffle three 43, and the bottom of baffle one 41, baffle two 42, and baffle three 43 are in contact with the upper surface of the packaging box. At this time, the anti-counterfeiting label is covered, and then the hot air blower 38 is started, and the hot air enters the enclosure through the air outlet pipe 39 to dry the ink; when the anti-counterfeiting label of the packaging box is dried, the packaging box continues to be transported to the left, and when the packaging box moves to the blanking plate 14, the packaging box slides to the top of the adjustment platform 12 with the blanking plate 14, and the multiple pushing blocks 50 slide toward the center of the adjustment platform 12 at the same time until the multiple pushing blocks 50 and the packaging box The four sides of the packaging box are fitted together, and then according to the side length of the packaging box, multiple limit frames 17 are made to slide on the limit rod 27, and the inner angle of the limit frame 17 is regarded as a corner of the square, so that the area of ​​the square formed by the angles of the multiple limit frames 17 is adjusted to be the same as the area of ​​the packaging box. At this time, the four corners of the packaging box are just aligned with the four corners of the limit frame 17; the suction cup 52 is made to contact with the bottom of the packaging box, and then the bottom of the packaging box is adsorbed by the suction cup 52 to drive the packaging box to rise. When the four corners of the packaging box are in contact with the inclined surface at the bottom of the support block 54, the support block 54 can be squeezed into the inner cavity of the sliding sleeve 18, and the spring 55 is compressed. When the lower end surface of the packaging box is higher than the upper end of the support block 54, the support block 54 can be pressed against the inner cavity of the sliding sleeve 18. When the surface is raised, the support block 54 is reset under the action of the spring 55, and the support block 54 can be used to support the packaging box. At this time, the placement of one packaging box can be completed, and whenever a packaging box is about to be placed on the support block 54 at the bottom of the limiting frame 17, the lifting plate 19 is moved horizontally to make the upper end surface of the lifting block 20 fit the bottom of the packaging box, and then the slide plate 24 is slid upward to make the lifting block 20 drive the placed packaging box to move upward, and again by squeezing the support block 54, the packaging box is moved upward by one layer, so as to provide a placement space for the packaging box at the bottom layer, and the above operations are repeated to stack multiple packaging boxes.
