[0002] When paper printed materials such as books and calendars need to be protected from moisture and sunlight, they are usually laminated. After lamination, the printed materials are not only wear-resistant, but different types of laminating materials can also enhance the visual effect. At the same time, they can also prevent the printed materials from being forged or tampered with, further increasing the value of the printed materials.

[0003] At present, when paper printed products are laminated, a laminating machine is usually used to automatically laminate the printed products. An adhesive coating is applied between the printed products and the film.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1

[0042] See also Figure 1-13 The present invention provides a technical solution: an automatic laminating system for printed products, comprising a laminating machine body 1, a laminating table 11 is carried on the laminating machine body 1, a gluing head 12 is arranged above the laminating table 11, a film 13 is arranged on one side of the gluing head 12, and the film 13 is located above the laminating table 11;

[0043] A detection module is used to detect whether there is adhesive on the laminating table 11, and if there is adhesive on the laminating table 11, a signal is sent to the control center;

[0044] The control center is used to receive the signal sent by the detection module, analyze the signal and obtain the analysis result;

[0045] A signal sending unit, used to send an execution instruction to the execution module according to the analysis result obtained by the control center;

[0046] An execution module, used to perform corresponding work according to the received execution instruction, the execution module includes: a smoothing mechanism 2, a scraping mechanism 3;

[0047] The smoothing mechanism 2 is used to evenly spread the adhesive on the laminating platform 11. The smoothing mechanism 2 is located above the laminating platform 11. The smoothing mechanism 2 can evenly spread the adhesive sprayed by the glue coating head 12;

[0048] The scraping mechanism 3 is used to scrape off the excess adhesive on the edge of the coated printed matter. The scraping mechanism 3 is located on both sides of the coating platform 11. The scraping mechanism 3 can scrape off the excess adhesive on the film 13 after coating.

[0049] The transmission member 4 is located between the smoothing mechanism 2 and the scraping mechanism 3, and the transmission member 4 can provide scraping power for the scraping mechanism 3 through the smoothing mechanism 2;

[0050] When the present invention is in use, after the glue coating head 12 sprays the adhesive, the sprayed adhesive can be automatically spread evenly, and at the same time, the transmission part 4 can provide scraping power for the scraping mechanism 3. The scraping mechanism 3 can scrape off the excess adhesive on the edge of the printed product after lamination to avoid excessive adhesive residue on the side of the laminating table 11, and the scraper 34 can also detect whether there is uneven glue coating on the laminating surface of the printed product. When in use, it can ensure the qualified rate of the printed product lamination and save manpower.

[0051] The smoothing mechanism 2 includes a reciprocating screw 21 rotatably connected to the inner wall of the laminating machine body 1, the reciprocating screw 21 is located between the glue coating head 12 and the film 13, and a motor 22 is fixedly connected to the outer wall of the laminating machine body 1. The motor 22 can drive the reciprocating screw 21 to rotate. A sliding block 23 is arranged on the periphery of the reciprocating screw 21, and the sliding block 23 is threadedly connected to the reciprocating screw 21. The sliding block 23 has a through hole 24, and a sliding rod 25 is slidably connected inside the through hole 24. Both ends of the sliding rod 25 are fixedly connected to the inner wall of the laminating machine body 1;

[0052] After starting the laminating machine body 1, the glue coating head 12 applies adhesive to the laminating table 11 to bond the printed matter to the film. Currently, a hyperspectral camera can be used to detect whether the adhesive exists. When the detection module detects that there is adhesive on the printed matter, the detection module sends a smoothing signal to the control center. The control center receives and analyzes the smoothing signal, and then sends a smoothing execution instruction to the execution module. At this time, the motor 22 is started, and the motor 22 can drive the reciprocating screw 21 to rotate. When the reciprocating screw 21 rotates, since the sliding block 23 is located outside the reciprocating screw 21, and the sliding rod 25 is located inside the through hole 24 opened by the sliding block 23, the sliding block 23 can slide back and forth outside the reciprocating screw 21. When the sliding block 23 moves back and forth, the adhesive on the laminating table 11 can be evenly spread through the smoothing member 5.

[0053] A smoothing member 5 capable of smoothing the adhesive sprayed from the glue coating head 12 is provided below the sliding block 23. The smoothing member 5 includes a positioning rod 51 fixedly connected below the sliding block 23. A positioning groove 52 is provided at the bottom of the positioning rod 51. A positioning cylinder 53 is rotatably connected to the periphery of the positioning rod 51. A positioning block 54 is fixedly connected to the inner wall of the positioning cylinder 53. The positioning block 54 is located in the positioning groove 52 and slides inside the positioning groove 52. A smoothing plate 55 is fixedly connected to the bottom of the positioning cylinder 53. A rope 56 is fixedly connected to the inner wall of the laminating machine body 1. The rope 56 is wound around the periphery of the positioning cylinder 53.

[0054] When the sliding block 23 drives the positioning cylinder 53 to slide through the positioning rod 51, since the positioning cylinder 53 is entangled by the rope 56, the rope 56 first twists the positioning cylinder 53 and drives the positioning cylinder 53 to rotate. Since the positioning block 54 fixedly connected to the inner wall of the positioning cylinder 53 is located inside the positioning groove 52 opened by the positioning rod 51, the positioning cylinder 53 no longer rotates when the positioning block 54 is engaged with the inner wall of the positioning groove 52. At this time, the smoothing plate 55 located at the bottom of the positioning cylinder 53 is at an oblique angle to the laminating table 11. The oblique smoothing plate 55 can drive the excess adhesive to move and spread the adhesive evenly, avoiding hollowing and glue accumulation during roller lamination, which is more convenient to use.

[0055] The transmission member 4 includes a belt 41 sleeved on the periphery of the reciprocating screw rod 21, a fixed rod 42 is fixedly connected to the inner wall of the laminating machine body 1, a fixed ring 43 is rotatably connected to the periphery of the fixed rod 42, the belt 41 is sleeved on the periphery of the fixed ring 43, and a bevel gear 44 is fixedly connected to one end of the fixed ring 43 close to the laminating table 11;

[0056] When the reciprocating screw 21 rotates, the reciprocating screw 21 drives the fixed ring 43 to rotate through the belt 41. At this time, the fixed ring 43 is located outside the fixed rod 42 and rotates. At the same time, the fixed ring 43 drives the bevel gear 44 to rotate. When the bevel gear 44 rotates, it can provide scraping power for the scraping mechanism 3, which is convenient for the scraping mechanism 3 to scrape off the excess adhesive on the edge of the printed product after lamination. It is very convenient to use.

[0057] The scraping mechanism 3 includes a support rod 31 fixedly connected to the inner wall of the laminating machine body 1, a support ring 32 is rotatably connected to the outer periphery of the support rod 31, a bevel gear 2 33 is fixedly connected to the end of the support ring 32 away from the laminating machine body 1, the bevel gear 2 33 is meshed with the bevel gear 1 44, the support ring 32 is located on one side of the laminating table 11, and a plurality of scrapers 34 are fixedly connected to the outer wall of the support ring 32, and the scrapers 34 are located above the laminating table 11;

[0058] The detection module uses a hyperspectral camera to detect whether there is any residual adhesive on the side of the coated printed matter. If there is excess adhesive, the detection module sends a scraping signal to the control center. The control center receives and analyzes the scraping signal and sends a scraping execution instruction to the execution module. At this time, when the bevel gear 1 44 rotates, since the bevel gear 1 44 is meshed with the bevel gear 2 33, the bevel gear 1 44 can drive the bevel gear 2 33 to rotate. At this time, the bevel gear 2 33 drives the support ring 32 located outside the support rod 31 to rotate. When the support ring 32 rotates, it can drive the scraper 34 to scrape off excess adhesive above the laminating table 11, thereby preventing excess adhesive from affecting the laminated printed matter. This can ensure the qualified rate of the printed matter lamination during use, making it more convenient to laminarize the printed matter.

[0059] Embodiment 2

[0060] See also Fig.14 The bottom of the positioning cylinder 53 is fixedly connected with an arc plate 57, and the arc plate 57 is located above the coating table 11. The arc plate 57 can collect excess adhesive to the arc surface, and when the sliding block 23 slides to the end of the reciprocating screw rod 21, the sliding block 23 moves in the opposite direction, and at the same time, the positioning cylinder 53 and the rope 56 rotate in the opposite direction, and the rope 56 twists the positioning cylinder 53 to rotate in the opposite direction. At this time, the positioning block 54 inside the positioning cylinder 53 slides in the positioning groove 52, and the positioning block 54 is clamped with the other end of the positioning groove 52. At this time, the arc plate 57 located at the bottom of the positioning cylinder 53 turns. Since the arc surface collects excess adhesive, the arc plate 57 can drive the adhesive to move, which is convenient for evenly applying the adhesive above the coating table 11.

[0061] Embodiment 3

[0062] See also Figure 15-17 A rotating groove 6 is provided on one side of each scraper 34, a rotating rod 61 is fixedly connected to the inner wall of the rotating groove 6, a trigger plate 62 is rotatably connected to the outer periphery of the rotating rod 61, the bottom of the trigger plate 62 abuts against the upper end of the laminating table 11, an electric contact 63 is fixedly connected to the inner wall of the rotating groove 6, the electric contact 63 is located on one side of the trigger plate 62, a warning light 64 is fixedly connected to the upper end of the scraper 34, and the electric contact 63 is circuit-connected to the warning light 64;

[0063] When there is no need to scrape off excess adhesive, the surface of the printed matter after lamination can be inspected by the scraper 34. When the scraper 34 passes over the hollow or glue-accumulated position of the printed matter, the trigger plate 62 is lifted up. At this time, the trigger plate 62 rotates around the rotating rod 61 inside the rotating groove 6. The upper end of the trigger plate 62 is in contact with the electrical contact 63. At this time, the prompt light 64 is energized and lights up to remind the staff to check the printed matter after lamination to ensure the qualified rate of the printed matter lamination.
