DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0019] Please refer to Figure 1 , Figure 6 , Figure 7 , Figure 8 ,Figure 9 and Figure 10 The anti-fake label printing glue equipment comprises a fixing frame 1, a glue printing assembly 2 and a glue spraying assembly 5. The glue spraying assembly 5 is installed on the top of the fixing frame 1, and the glue printing assembly 2 is installed on the side of the fixing frame 1. The glue printing assembly 2 comprises a glue printing roller 27 reciprocating on the top of the fixing frame 1. The glue printing roller 27 reciprocates twice to print glue on the anti-fake label. The glue spraying assembly 5 comprises a guard plate 50, a scraper 62 and a collecting plate 73. When the glue printing roller 27 moves to the inside of the guard plate 50, the scraper 62 and the collecting plate 73 move to the top and bottom of the glue printing roller 27 respectively to prevent glue from dripping due to excessive glue.
[0020] Specifically, the glue printing roller 27 reciprocates between the two guard plates 50 when printing glue. The glue printing roller 27 reciprocates multiple times to print glue on the anti-fake label 13 to ensure complete printing. When the glue printing roller 27 moves to the inside of the guard plate 50, the scraper 62 removes the excess glue on the glue printing roller 27 to prevent excessive glue. At the same time, the collecting plate 73 moves to the bottom of the glue printing roller 27 to collect the excess glue, preventing the glue from falling off and adhering to the anti-fake label 13, which affects the quality of the label. In the traditional glue printing equipment, the glue printing roller experiences frequent start-stop conversion during reciprocation, especially in the stopping moment, which produces slight vibration due to inertia, causing the glue attached to the roller surface to fall off, not only polluting the equipment and the label, but also causing excessive or insufficient glue in some areas, affecting the overall quality and anti-fake effect of the label. It should be noted that when the glue printing roller 27 enters the inside of the guard plate 50, the electric control valve of the connecting pipe 51 is opened, and the glue is sprayed onto the glue printing roller 27 through the nozzle. At the same time, the collecting plate 73 below can also shield the anti-fake label below to prevent the sprayed glue from adhering to the anti-fake label, achieving the protection effect and improving the glue printing quality.
[0021] Please refer to Figure 1 , Figure 2 and Figure 3The outer wall of the fixed frame 1 is equipped with a drive motor 11. A conveyor belt 12 is mounted around the output end of the drive motor 11. Multiple anti-counterfeiting labels 13 are placed above the conveyor belt 12. The printing assembly 2 includes a fixed box 20 installed on one side of the fixed frame 1. Fixed plates 21 are installed on both outer walls of the fixed frame 1. A gear groove 22 is opened on the top of the fixed plate 21. A sliding groove 23 is opened on the top of the fixed plate 21. A sliding plate 24 is slidably installed above the sliding groove 23. A first motor 25 is fixedly installed on the top of the sliding plate 24. A rotating shaft 26 is installed at the output end of motor 5. A printing roller 27 is installed at one end of the rotating shaft 26. A driven component 4 is installed above the other sliding plate 24. A driving component 3 is installed on the top of the sliding plate 24. The driving component 3 includes a fixed housing 30 installed above the sliding plate 24. The fixed housing 30 is located on one side of the first motor 25. A motor 31 is installed on the inner wall of the fixed housing 30. A driving shaft 32 is installed at the output end of the motor 31. A plurality of driving gears 33 are installed on the outer wall of the driving shaft 32, and the driving gears 33 mesh with the gear groove 22.
[0022] Specifically, first, the anti-counterfeiting label 13 is placed on the conveyor belt 12, and the drive motor 11 drives the conveyor belt 12 to rotate, moving the anti-counterfeiting label 13 to the printing area. At this time, the printing roller 27 is in the position as shown in the image. Figure 1 In the right-side guard plate 50 shown, the connecting pipe 51 sprays the adhesive onto the printing roller 27. The scraper 62 and the collecting plate 73 extend out. The scraper 62 spreads the sprayed adhesive evenly on the printing roller 27, and the collecting plate 73 prevents the adhesive from dripping onto the anti-counterfeiting label 13. Then, the first motor 25 rotates, driving the rotating shaft 26 and the printing roller 27 to rotate. At the same time, the motor 31 drives the drive shaft 32 and the drive gear 33 to rotate. The drive gear 33 meshes with the gear groove 22, thereby driving the sliding plate 24 to move to the left. The printing roller 27 rotates itself while moving to the left, printing the adhesive on the surface of the printing roller 27 onto the anti-counterfeiting label 13, thus realizing the printing function. It should be noted that during the process of the printing roller 27 moving from the right to the left, it prints adhesive on multiple anti-counterfeiting labels on the conveyor belt 12. During this continuous printing process, the adhesive is constantly consumed, with the rightmost anti-counterfeiting label 13 having the most adhesive and the leftmost label having the least, resulting in uneven adhesive content and affecting the quality of the anti-counterfeiting labels 13. Therefore, when the printing roller 27 moves from the left or right side to the leftmost guard plate 50, the left guard plate 50 performs the same adhesive spraying and scraping operation, so that the printing roller 27 prints adhesive on the anti-counterfeiting labels a second time during the movement from left to right. At this time, the leftmost anti-counterfeiting label 13 has the most adhesive and the rightmost label has the least. By printing adhesive twice, it is possible to ensure that the adhesive content of each anti-counterfeiting label is the same, greatly improving the quality of the anti-counterfeiting label printing.
[0023] Please see Figure 1 ,Figure 2 、 Figure 4 and Figure 5 , the driven assembly 4 includes a driven shell 40 installed above the sliding plate 24, a lifting rod 41 is installed through the top of the driven shell 40, the outer wall of the lifting rod 41 is installed with a first spring 42, a guide wheel 43 is installed on the inner wall of the driven shell 40, two fixed shafts 44 are installed on the inner wall of the driven shell 40, the outer wall of the fixed shaft 44 is installed with an arc-shaped speed reduction plate 45, the outer wall of the speed reduction plate 45 is installed with a speed reduction piece 46, one end of the speed reduction plate 45 is installed with a fixed ring 47, the outer wall of the fixed ring 47 is installed with a reset spring 48, a second guide wheel 49 is installed on the inner wall of the driven shell 40, and the fixed ring 47, the second guide wheel 49, the guide wheel 43 and the lifting rod 41 are connected through a cable, and the two speed reduction plates 45 are divided on both sides of the rotating shaft 26.
[0024] Specifically, the driven assembly 4 moves synchronously with the glue printing roller 27, when the driven shell 40 moves to the lower side of the guard plate 50, the guard plate 50 will press the lifting rod 41, the lifting rod 41 will be lowered to drive the first spring 42 to be elongated, at this time the lifting rod 41 will pull the cable downward, the cable will pull the fixed ring 47 to be close to each other through the guide wheel 43 and the second guide wheel 49, the fixed ring 47 will drive the speed reduction plate 45 and the speed reduction piece 46 to be close to the outer wall of the rotating shaft 26, so as to slow down the rotating shaft 26; It should be noted that after the glue printing roller 27 completes a glue printing, enters the guard plate 50, the glue printing roller 27 is slowed down by the speed reduction plate 45 and the speed reduction piece 46, the rotating speed of the glue printing roller 27 is reduced, so as to prevent the glue from dropping due to the too fast rotating speed in the process of re-spraying glue, in addition, when the glue printing roller 27 moves to the inside of the guard plate 50, its movement state will suddenly stop, then reversely moves after the glue spraying is completed, at the moment of movement stop, the glue printing roller 27 will shake due to inertia, which will cause the glue on the glue printing roller 27 to fall off, the rotation of the glue printing roller 27 will promote the glue to fall off, so as to cause the glue printing roller 27 to drop glue, the excess glue is added on the anti-fake label 13, which causes the quality problem of the glue printing of the anti-fake label 13; It should be noted that first, the motor 31 drives the sliding plate 24 to reciprocate through the driving gear 33 and the gear groove 22, the motor 31 adopts a servo motor, which starts to uniformly slow down before entering the guard plate 50 through program control of the servo motor until stop, after the glue spraying is completed, the servo motor adopts uniform acceleration, and accelerates to a suitable speed and then moves at a constant speed, through the above-mentioned mode, the probability of glue dropping due to inertia stop of the glue printing roller 27 can be greatly reduced, and the glue printing quality is effectively improved.

[0026] Specifically, when the driven shell 40 moves into the protective plates 50, the driven shell 40 extrudes the trigger rod 52, the trigger rod 52 is extruded to move to the outside of the protective plates 50, at the same time, the tooth grooves 53 drive the connecting gear 55 to rotate, so that the passive rod 6 and the collecting rod 71 start to move to the inside of the protective plates 50, and then drive the scraper 62 and the collecting plate 73 to enter the protective plates 50 through the glue scraping groove 56 and the collecting groove 72 respectively, at the same time, the driven shell 40 contacts the trigger switch 57, so that the trigger switch 57 controls the electric control valve to open, the connecting pipes 51 start to spray glue on the rubber printing roller 27, in this process, the rubber printing roller 27 is in a slow rotating state, the scraper 62 scrapes the rubber printing roller 27 to remove excess glue, and then the excess glue falls on the collecting plate 73 to prevent the anti-fake label 13 from being contaminated, after the glue spraying is completed, the trigger rod 52, the passive rod 6 and the collecting rod 71 return to the original positions under the action of the second spring 64 and the third spring 75.
