[0017] 3. After the airflow is discharged through the end of the ventilation slot, it will pass through the movable cover. Under the guidance of the inclined surface of the movable cover, the airflow will quickly pass between the lower end surface of the movable cover and the plastic film (the area through which the airflow can pass is reduced and the flow rate is accelerated), thereby quickly drying the printed layer on the surface of the plastic film. In this process, each small exhaust fan also works to guide the water vapor entrained in the passing airflow upward and away from the plastic film. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1-Figure 11A processing equipment for producing double-layer anti-counterfeiting packaging bags comprises two base side plates 1, a pair of lower material guide rollers 2 and a pair of lower material guide rollers 3 are rotatably arranged between the two base side plates 1, a vertical plate 4 is fixed on the upper end surface of each base side plate 1, an upper material guide roller 5 is rotatably arranged between the two vertical plates 4, a vertical plate 26 is fixed on the upper end surface of each base side plate 1, an upper material guide roller 27 is rotatably arranged between the two vertical plates 26, two roller printing components are arranged between the two base side plates 1, a plurality of quick air drying components are arranged between the upper material guide roller 5 and the upper material guide roller 27, and the driving of the lower material guide roller 2, the lower material guide roller 23, the upper material guide roller 5 and the upper material guide roller 27 is realized by the prior art.

[0022] The present application is used to process a packaging bag body 41. A printing layer 1 42 is provided on the surface of the packaging bag body 41. The printing layer 1 42 includes an anti-counterfeiting pattern 1 43 and an anti-counterfeiting pattern 2 44. A variable printing layer 2 45 is provided on the surface of the printing layer 1 42. The variable printing layer 2 45 covers the surface of the anti-counterfeiting pattern 2 44. The variable printing layer 2 45 is water-sensitive.

[0023] Reference Figure 1 and Figure 2 When the packaging bag body 41 is in use, when the variable printing layer 2 45 is in a dry state, the variable printing layer 2 45 is in a display state, and the variable printing layer 2 45 covers the surface of the anti-counterfeiting pattern 2 44. The user cannot see the anti-counterfeiting pattern 2 44, but can only see the anti-counterfeiting pattern 1 43. When the variable printing layer 2 45 is wiped with water, the variable printing layer 2 45 is moistened. At this time, the variable printing layer 2 45 is in a transparent state, and the user can observe the anti-counterfeiting pattern 2 44 through the variable printing layer 2 45, which is convenient for verification.

[0024] By cooperating with the anti-counterfeiting pattern 1 43, the anti-counterfeiting pattern 2 44 and the variable printing layer 2 45, the packaging bag body 41 is provided with double-layer anti-counterfeiting protection. The variable printing layer 2 45 can be printed by finished ink using conventional technology. For example, the ink model ZHT of Jiangsu Tiger Ink Co., Ltd. can be selected.

[0025] During the production process of the packaging bag body 41 , the plastic film 46 constituting the packaging bag body 41 needs to be printed. After the printing layer 1 42 and the variable printing layer 2 45 are printed, the plastic film 46 is formed into the packaging bag body 41 by existing equipment.

[0026] Reference Figure 3 and Figure 4When the packaging bag body 41 is produced and processed, the plastic film 46 is guided by the lower guide roller 2 and passes through the adjacent roller printing component. The upper printing layer 42 is printed on the surface of the plastic film 46 through the set roller printing component. The plastic film 46 that has been printed for the first time is guided by the upper guide roller 5 and passes through multiple fast air-drying components. During this process, the printing layer 42 printed on the surface of the plastic film 46 is quickly blown dry to avoid affecting the printing of the variable printing layer 45. After the plastic film 46 passes through the fast air-drying component, it is guided by the upper guide roller 7 and passes through the corresponding roller printing component. During this process, the printing of the variable printing layer 45 is completed, which is convenient to use.

[0027] The movement of the plastic film 46 and the adjustment of the tension are both conventional technical means in the art.

[0028] Reference Figure 3-Figure 7 A plurality of pairs of intermediate plates 8 are fixed to the upper end surfaces of the two base side plates 1, and a receiving roller 9 is rotatably arranged between each pair of intermediate plates 8. A mounting seat 10 is arranged on each pair of intermediate plates 8, and a pressing roller 11 is rotatably arranged through the side wall of each mounting seat 10. The mounting seats 10 on the same side are arranged at intervals, and a driving unit that cooperates with the rotation of the plurality of receiving rollers 9 is arranged on the intermediate plate 8. The driving unit that realizes the rotation of the plurality of receiving rollers 9 is the prior art.

[0029] The mounting seat 10 is provided with a mounting groove for cooperating with the pressing roller 11. The pressing roller 11 rotates through the mounting groove. A bearing is sleeved on the outer surface of the pressing roller 11. An annular groove for cooperating with the bearing is provided on the inner wall of the mounting groove. The bearing is fixed in the annular groove.

[0030] Reference Figure 3-Figure 7 After the plastic film 46 is guided by the upper material guide roller 5, the plastic film 46 passes between the receiving roller 9 and the corresponding pressing roller 11. The cooperation between the receiving roller 9 and the pressing roller 11 can prevent the plastic film 46 from vibrating significantly during the rapid air-drying process, thereby affecting the transportation of the plastic film 46. In addition, the mounting seats 10 on the same side are arranged at intervals to prevent too many mounting seats 10 from affecting the flow of airflow generated by the rapid air-drying component, thereby further reducing the impact on the transportation stability of the plastic film 46.

[0031] Reference Figure 6 and Figure 7Each quick air-drying component includes a through ventilation slot 12 opened at one end of the corresponding pressing roller 11, and each through ventilation slot 12 is rotatably provided with an adapter 13 at one end close to the mounting seat 10. The adapter 13 and the installation of the adapter 13 are prior arts. The ends of the adapters 13 located on the same side are fixedly connected to the same branch pipe 14, and an air pump 15 is fixedly provided on the upper end surface of each base side panel 1, and an air supply pipe 16 is fixedly connected between the air outlet end of the air pump 15 and the corresponding branch pipe 14.

[0032] Reference Figure 6 and Figure 7 When in use, the air pump 15 works to generate air flow, which is guided by the air supply pipe 16, the branch pipe 14 and the adapter 13, and is blown out from the ventilation slot 12 at the end of the pressing roller 11, thereby quickly drying the upper surface of the plastic film 46.

[0033] Reference Figure 6 and Figure 7 Upper connecting blocks 17 are fixed on both sides of each mounting seat 10, and a guide rod 18 is fixed on the lower end surface of each upper connecting block 17. Lower connecting blocks 19 are fixed on both sides of the corresponding intermediate plate 8, and each guide rod 18 movably passes through the lower connecting block 19. A spring 20 is fixed between each upper connecting block 17 and the lower connecting block 19, and each spring 20 is movably sleeved on the outer surface of the corresponding guide rod 18.

[0034] Reference Figure 6 and Figure 7 A passive gear ring 21 is fixedly sleeved on the outer surface of one end of each pressing roller 11 close to the mounting seat 10. The central axis of the receiving roller 9 located below the pressing roller 11 rotates through the middle plate 8 and is fixedly sleeved with a driving gear ring 22, which is meshed and connected with the passive gear ring 21.

[0035] Reference Figure 6 and Figure 7 During the preliminary installation and debugging, when the plastic film 46 passes through the receiving roller 9 and the pressing roller 11, first pull the mounting seat 10 upwards, and the mounting seat 10 drives the upper connecting block 17 and the spring 20 to move, and then the plastic film 46 passes through the corresponding receiving roller 9 and the pressing roller 11, and then slowly move the mounting seat 10 downward until the pressing roller 11 contacts the surface of the plastic film 46. At this time, the receiving roller 9 is pressed on the surface of the plastic film 46 under the action of the elastic force of the spring 20 and the gravity of the mounting seat 10 itself, so as to avoid the plastic film 46 from shaking greatly when the airflow passes through the surface of the plastic film 46. When the receiving roller 9 rotates, the active gear ring 22 drives the passive gear ring 21 to rotate, thereby driving the pressing roller 11 to rotate together, and cooperate with the conveying of the plastic film 46.

[0036] Reference Figure 3 , Figure 5 , Figure 8 and Fig. 9 A same horizontal plate 23 is fixed to the upper end surface of each vertical plate 4 and the corresponding vertical plate 2 6, and a movable cover 24 is movably arranged between the two horizontal plates 23. Both sides of the movable cover 24 and the lower section are inclined, and the upper and lower end surfaces of the movable cover 24 are open. The size of the lower end surface of the movable cover 24 is larger than the size of the printing layer 42. A built-in plate 25 is fixed on the inner wall of the movable cover 24 and close to the lower end. A plurality of mounting grooves are formed through the upper end surface of the built-in plate 25, and a small exhaust fan 26 is arranged in each mounting groove. The lower end surface of the small exhaust fan 26 is the air inlet end, and the upper end surface of the small exhaust fan 26 is the air outlet end.

[0037] Reference Figure 3 , Figure 5 , Figure 8 and Fig. 9 When the airflow is discharged through the end of the ventilation slot 12, it will pass through the movable cover 24. Under the guidance of the inclined surface of the movable cover 24, the airflow will quickly pass between the lower end surface of the movable cover 24 and the plastic film 46 (the cross-section through which the airflow can pass is reduced, and the flow rate is accelerated), thereby quickly drying the printed layer 42 on the surface of the plastic film 46. In this process, each small exhaust fan 26 also works to guide the water vapor entrained in the passing airflow upward and away from the plastic film 46.

[0038] Reference Figure 8 A plurality of guide posts 27 are fixed between the two horizontal plates 23, and each guide post 27 movably penetrates the movable cover 24. A screw rod 28 is rotatably arranged between the two horizontal plates 23, and the screw rod 28 threadably penetrates the movable cover 24. One end of the screw rod 28 rotatably penetrates the horizontal plate 23 and is fixedly connected to a rotating wheel 29.

[0039] The rotating wheel 29 can be used to drive the screw rod 28 to rotate, thereby adjusting the position of the movable cover 24 as required.

[0040] Reference Figure 4 and Fig.10 Each roller printing assembly includes a solution box 30 fixed on the inner wall of the base side plate 1, a slurry feeding roller 31 is rotatably provided on the inner wall of the solution box 30, a transfer roller 32 and an auxiliary roller 33 used in conjunction with the corresponding solution box 30 are rotatably provided on the inner wall of the base side plate 1, a notch used in conjunction with the transfer roller 32 is provided on the solution box 30, a scraper 34 used in conjunction with the slurry feeding roller 31 is fixed on the inner wall of the solution box 30, and the excess printing paint on the surface of the slurry feeding roller 31 is scraped off by the provided scraper 34, and this part of the structure is all prior art.

[0041] Reference Figure 4 and Fig.10The solution box 30 is filled with corresponding printing paint, the lower part of the slurry roller 31 is immersed in the printing paint, the transfer roller 32 and the slurry roller 31 rotate in coordination, so that the corresponding position of the slurry roller 31 adheres to the printing paint, and the transfer roller 32 and the auxiliary roller 33 rotate in coordination to print the printing paint on the transfer roller 32 on the plastic film 46.

[0042] Reference Figure 4 , Fig.10 and Fig.11 A stirring roller 35 is rotatably provided on the inner wall of each solution box 30, and a plurality of stirring blades 36 are fixed on the outer surface of the stirring roller 35.

A plurality of protrusions 38 are fixed on the outer surface of the linkage roller 37. The central axis of each stirring roller 35 and the central axis of the linkage roller 37 both rotatably penetrate the base side plate 1 and are fixedly sleeved with a linkage toothed disc 39, and a chain 40 is provided for transmission on two adjacent linkage toothed discs 39.

[0043] Reference Figure 4 , Fig.10 and Fig.11 During use, the stirring roller 35 drives the stirring blades 36 to rotate, stirring the printing paint in the solution tank 30 to avoid partial condensation of the printing paint. During the rotation of the stirring roller 35, the linkage roller 37 and the protrusions 38 are driven to rotate together through the cooperation of the linkage toothed plate 39 and the chain 40. During the rotation, the protrusion 38 will collide with the end of the scraper 34, causing the scraper 34 to vibrate, thereby prompting the printing paint adhering to the surface of the scraper 34 to drip quickly, avoiding the printing paint from condensing on the scraper 34.

[0044] When the present invention is used, refer to Figure 1 and Figure 2 When the variable printing layer 2 45 is in a dry state, the variable printing layer 2 45 is in a display state, and the variable printing layer 2 45 covers the surface of the anti-counterfeiting pattern 2 44. The user cannot see the anti-counterfeiting pattern 2 44, but can only see the anti-counterfeiting pattern 1 43. When the variable printing layer 2 45 is wiped with water to wet the variable printing layer 2 45, the variable printing layer 2 45 is in a transparent state at this time, and the user can observe the anti-counterfeiting pattern 2 44 through the variable printing layer 2 45, which is convenient for verification; Reference Figure 3 and Figure 4When the packaging bag body 41 is produced and processed, the plastic film 46 is guided by the lower guide roller 2 and passes through the adjacent roller printing assembly. The upper printing layer 42 is printed on the surface of the plastic film 46 through the provided roller printing assembly. The plastic film 46 after the first printing is guided by the upper guide roller 5 and passes through multiple fast air-drying assemblies. In this process, the printing layer 42 printed on the surface of the plastic film 46 is quickly dried to avoid affecting the printing of the variable printing layer 2 45. After the plastic film 46 passes through the fast air-drying assembly, it is guided by the upper guide roller 2 7 and passes through the corresponding roller printing assembly. In this process, the printing of the variable printing layer 2 45 is completed, which is convenient to use. Reference Figure 3-Figure 7 After the plastic film 46 is guided by the upper guide roller 5, the plastic film 46 passes between the receiving roller 9 and the corresponding pressing roller 11. The cooperation between the receiving roller 9 and the pressing roller 11 can prevent the plastic film 46 from vibrating greatly during the rapid air-drying process, thereby affecting the conveying of the plastic film 46. In addition, the mounting seats 10 on the same side are arranged at intervals to prevent too many mounting seats 10 from affecting the flow of the airflow generated by the rapid air-drying component, thereby further reducing the impact on the conveying stability of the plastic film 46. Reference Figure 3 , Figure 5 , Figure 8 and Fig. 9 When the airflow is discharged through the end of the ventilation slot 12, it will pass through the movable cover 24. Under the guidance of the inclined surface of the movable cover 24, the airflow will quickly pass between the lower end surface of the movable cover 24 and the plastic film 46 (the area through which the airflow can pass is reduced, and the flow rate is accelerated), so as to quickly air-dry the printed layer 42 on the surface of the plastic film 46. In this process, each small exhaust fan 26 also works to guide the water vapor carried by the passing airflow upward and away from the plastic film 46. Reference Figure 4 and Fig.10 The solution box 30 is filled with corresponding printing paint, the lower section of the slurry feeding roller 31 is immersed in the printing paint, the transfer roller 32 and the slurry feeding roller 31 rotate in coordination, so that the printing paint adheres to the corresponding position of the slurry feeding roller 31, and the transfer roller 32 and the auxiliary roller 33 rotate in coordination to print the printing paint on the transfer roller 32 on the plastic film 46; Reference Figure 4 , Fig.10 and Fig.11During use, the stirring roller 35 drives the stirring blades 36 to rotate, stirring the printing paint in the solution tank 30 to prevent partial condensation of the printing paint. During the rotation of the stirring roller 35, the linkage roller 37 and the protrusions 38 are driven to rotate together through the cooperation of the linkage toothed plate 39 and the chain 40. During the rotation, the protrusion 38 will collide with the end of the scraper 34, causing the scraper 34 to vibrate, thereby prompting the printing paint adhering to the surface of the scraper 34 to drip quickly, preventing the printing paint from condensing on the scraper 34.
