A chain is arranged in a transmission manner on adjacent two linkage gear discs.

[0017] Advantages of the present invention:

[0018] 1. When the packaging bag body is produced and processed, the plastic film is fed by the lower material guiding roller 1 and will pass through adjacent roll printing assemblies. Through the provided roll printing assemblies, a first printing layer is printed on the surface of the plastic film. The plastic film after the first printing is fed by the upper material guiding roller 1 and will pass through a plurality of rapid air drying assemblies. During this process, the first printing layer printed on the surface of the plastic film is quickly dried to avoid affecting the printing of the variable printing layer 2. When the plastic film passes through the rapid air drying assemblies, through the feeding of the upper material guiding roller 2, the plastic film will pass through the corresponding roll printing assemblies. During this process, the variable printing layer 2 is printed, which is convenient to use.

[0019] 2. After the plastic film is fed by the upper material guiding roller 1, the plastic film passes between the receiving roller and the corresponding pressing roller. Through the cooperation of the receiving roller and the pressing roller, it is avoided that the plastic film shakes greatly during the rapid air drying process, which affects the conveying of the plastic film. And the mounting seats on the same side are arranged at intervals, avoiding that too many mounting seats affect the flow of the air flow generated by the rapid air drying assemblies, and further reducing the influence on the conveying stability of the plastic film.

[0020] 3. After the air flow is discharged from the end of the through ventilation groove, it will pass through the moving cover. Under the guiding of the inclined surface of the moving cover, the air flow will quickly pass through between the lower end surface of the moving cover and the plastic film (the area through which the air flow can pass decreases, and the flow rate increases), so as to quickly dry the first printing layer on the surface of the plastic film. And during this process, each small exhaust fan also works to guide the water vapor carried in the passing air flow upward, away from the plastic film. Description of the drawings

Detailed implementation manners

[0033] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features and their effects of the present invention as follows.

[0034] Refer to Figures 1 - 11 , a processing device for producing a double-layer anti-counterfeiting packaging bag, including two base side plates 1. A pair of lower material guiding rollers 1 and a pair of lower material guiding rollers 2 are rotatably arranged between the two base side plates 1. A vertical plate 1 is fixed on the upper end surface of each base side plate 1. An upper material guiding roller 1 is rotatably arranged between the two vertical plates 1. A vertical plate 2 is fixed on the upper end surface of each base side plate 1. An upper material guiding roller 2 is rotatably arranged between the two vertical plates 2. Two roller printing assemblies are arranged between the two base side plates 1. A plurality of fast drying assemblies are arranged between the upper material guiding roller 1 and the upper material guiding roller 2. The driving of the lower material guiding roller 1, the lower material guiding roller 2, the upper material guiding roller 1 and the upper material guiding roller 2 is the prior art.

[0035] This application is used to process the packaging bag body 41. A printing layer 1 is provided on the surface of the packaging bag body 41. The printing layer 1 includes an anti-counterfeiting pattern 1 and an anti-counterfeiting pattern 2. A variable printing layer 2 is provided on the surface of the printing layer 1. The variable printing layer 2 covers the surface of the anti-counterfeiting pattern 2. The variable printing layer 2 has water sensitivity.

[0036] Refer to Figure 1 and Figure 2 , when the packaging bag body 41 is in use, when the variable printing layer 2 is in a dry state, the variable printing layer 2 is in a display state. The variable printing layer 2 covers the surface of the anti-counterfeiting pattern 2. The user cannot see the anti-counterfeiting pattern 2 and can only see the anti-counterfeiting pattern 1. When the variable printing layer 2 is wiped with water, the variable printing layer 2 is wetted. At this time, the variable printing layer 2 is in a transparent state. The user can observe the anti-counterfeiting pattern 2 through the variable printing layer 2, which is convenient for verification.

[0037] Through the cooperation of the set anti-counterfeiting pattern 1, anti-counterfeiting pattern 2 and variable printing layer 2, double-layer anti-counterfeiting protection is carried out on the packaging bag body 41. The variable printing layer 2 can be printed from finished ink by conventional techniques. For example, the ink of model ZHT of Jiangsu Tiger Ink Co., Ltd. can be selected.

[0038] In the production and processing process of the packaging bag body 41, it is necessary to print and process the plastic film 46 that constitutes the packaging bag body 41. After the printing layer 1 and the variable printing layer 2 are printed, the plastic film 46 is formed into the packaging bag body 41 through existing equipment.

[0039] Refer toFigure 3 and Figure 4 When the packaging bag body 41 is being produced and processed, the plastic film 46 is fed by the lower material guiding roller 2 and will pass through adjacent roller printing assemblies. Through the set roller printing assemblies, a first printing layer 42 is printed on the surface of the plastic film 46. The plastic film 46 after the first printing is fed by the upper material guiding roller 1 5 and will pass through multiple rapid air drying assemblies. During this process, the first 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 45. When the plastic film 46 passes through the rapid air drying assemblies, through the feeding of the upper material guiding roller 2 7, the plastic film 46 will pass through the corresponding roller printing assemblies. During this process, the variable printing layer 45 is printed, which is convenient to use.

[0040] The movement of the plastic film 46 and the adjustment of the tension are both conventional technical means in the art.

[0041] Refer to Figures 3 - 7 As shown in [reference figure], a plurality of pairs of intermediate plates 8 are fixed on the upper end surfaces of the two base side plates 1. A receiving roller 9 is rotatably arranged between each pair of intermediate plates 8. An installation seat 10 is arranged on each pair of intermediate plates 8. A pressing roller 11 is rotatably penetrated through the side wall of each installation seat 10. The installation seats 10 on the same side are arranged at intervals. A driving unit for driving the rotation of the plurality of receiving rollers 9 is arranged on the intermediate plate 8, and the driving unit for realizing the rotation of the plurality of receiving rollers 9 is prior art.

[0042] An installation through groove for cooperating with the pressing roller 11 is opened on the installation seat 10. The pressing roller 11 is rotatably penetrated through the installation through groove. A bearing is sleeved on the outer surface of the pressing roller 11. An annular groove for cooperating with the bearing is opened on the inner wall of the installation through groove, and the bearing is fixed in the annular groove.

[0043] Refer to Figures 3 - 7 As shown in [reference figure], when the plastic film 46 is fed by the upper material guiding roller 1 5, the plastic film 46 passes between the receiving roller 9 and the corresponding pressing roller 11. Through the cooperation of the receiving roller 9 and the pressing roller 11, it is avoided that the plastic film 46 shakes greatly during the rapid air drying process, which affects the conveying of the plastic film 46. And the installation seats 10 on the same side are arranged at intervals, avoiding that too many installation seats 10 affect the flow of the air flow generated by the rapid air drying assemblies, and further reducing the influence on the conveying stability of the plastic film 46.

[0044] Refer to Figure 6 and Figure 7, each quick air-drying component includes a through ventilation groove 12 opened at one end of the corresponding pressing roller 11. At one end of each through ventilation groove 12 close to the mounting base 10, a swivel joint 13 is rotatably provided. The swivel joint 13 and its installation are prior arts. The ends of the swivel joints 13 on the same side are fixedly connected to the same sub-manifold 14. On the upper end face of each base side plate 1, a blowing pump 15 is fixedly installed. A supply air duct 16 is fixedly connected between the air outlet end of the blowing pump 15 and the corresponding sub-manifold 14.

[0045] Refer to Figure 6 and Figure 7 , during use, the blowing pump 15 operates to generate air flow. Through the conveyance of the supply air duct 16, the sub-manifold 14, and the swivel joint 13, the air flow blows out from the through ventilation groove 12 at the end of the pressing roller 11, thereby quickly air-drying the upper surface of the plastic film 46.

[0046] Refer to Figure 6 and Figure 7 , on both sides of each mounting base 10, an upper connecting block 17 is fixedly installed. On the lower end face of each upper connecting block 17, a guide rod 18 is fixedly installed. On both sides of the corresponding intermediate plate 8, a lower connecting block 19 is fixedly installed. Each guide rod 18 movably penetrates through the lower connecting block 19. A spring 20 is fixedly installed between each upper connecting block 17 and the lower connecting block 19. Each spring 20 is movably sleeved on the outer surface of the corresponding guide rod 18.

[0047] Refer to Figure 6 and Figure 7 , on the outer surface of one end of each pressing roller 11 close to the mounting base 10, a passive gear ring 21 is fixedly sleeved. The central axis of the receiving roller 9 located below the pressing roller 11 rotatably penetrates through the intermediate plate 8 and is fixedly sleeved with an active gear ring 22. The active gear ring 22 is meshed and connected with the passive gear ring 21.

[0048] Refer to Figure 6 and Figure 7 , during the initial installation and debugging process, when passing the plastic film 46 through the receiving roller 9 and the pressing roller 11, first pull up the mounting base 10. The mounting base 10 drives the upper connecting block 17 and the spring 20 to move. Then pass the plastic film 46 through the corresponding receiving roller 9 and pressing roller 11. Then slowly lower the mounting base 10 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 self-weight of the mounting base 10, avoiding large fluctuations of the plastic film 46 when the air flow passes through the surface of the plastic film 46. When the receiving roller 9 rotates, it drives the passive gear ring 21 to rotate through the active gear ring 22, thereby driving the pressing roller 11 to rotate together to cooperate with the conveyance of the plastic film 46.

[0049] Refer to Figure 3 、Figure 5 , Figure 8 and Figure 9 , on the upper end surfaces of each vertical plate one 4 and the corresponding vertical plate two 6, there is a same transverse plate 23 fixed. A moving cover 24 is movably arranged between the two transverse plates 23. Both sides of the moving cover 24 and at the lower position are inclined. Both the upper and lower end surfaces of the moving cover 24 are open. The size of the lower end surface of the moving cover 24 is larger than the size of the printing layer one 42. An inner built-in plate 25 is fixed on the inner wall of the moving cover 24 and near the lower end position. A plurality of installation through grooves are formed through the upper end surface of the inner built-in plate 25. A small exhaust fan 26 is arranged in each installation through 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.

[0050] Referring to Figure 3 , Figure 5 , Figure 8 and Figure 9 , after the air flow is discharged through the end of the through ventilation groove 12, it will pass through the moving cover 24. Under the guiding of the inclined surface of the moving cover 24, the air flow will quickly pass through between the lower end surface of the moving cover 24 and the plastic film 46 (the cross-section through which the air flow can pass decreases, and the flow rate increases), so as to quickly air-dry the printing layer one 42 on the surface of the plastic film 46. And during this process, each small exhaust fan 26 also works to guide the water vapor carried in the passing air flow upward, away from the plastic film 46.

[0051] Referring to Figure 8 , a plurality of guiding columns 27 are fixed between the two transverse plates 23. Each guiding column 27 movably penetrates through the moving cover 24. A lead screw 28 is rotatably arranged between the two transverse plates 23. The lead screw 28 threadedly penetrates through the moving cover 24. One end of the lead screw 28 rotatably penetrates through the transverse plate 23 and is fixedly connected with a runner 29.

[0052] By setting the runner 29, the lead screw 28 can be driven to rotate, so as to adjust the position of the moving cover 24 as needed.

[0053] Referring to Figure 4 and Figure 10 , each roller printing assembly includes a solution tank 30 fixed on the inner wall of the base side plate 1. A slurry feeding roller 31 is rotatably arranged on the inner wall of the solution tank 30. A transfer roller 32 and an auxiliary roller 33 used in cooperation with the corresponding solution tank 30 are rotatably arranged on the inner wall of the base side plate 1. A notch used in cooperation with the transfer roller 32 is arranged on the solution tank 30. A scraper 34 used in cooperation with the slurry feeding roller 31 is fixed on the inner wall of the solution tank 30. By setting the scraper 34, the excess printing coating on the surface of the slurry feeding roller 31 is scraped off. This part of the structure is all prior art.

[0054] Referring to Figure 4 and Figure 10, the solution tank 30 is filled with corresponding printing coatings. The lower part of the coating roller 31 is immersed in the printing coatings. The transfer roller 32 and the coating roller 31 rotate in cooperation, causing the corresponding positions of the coating roller 31 to adhere to the printing coatings. The transfer roller 32 and the auxiliary roller 33 rotate in cooperation to print the printing coatings on the transfer roller 32 onto the plastic film 46.

[0055] Refer to Figure 4 , Figure 10 and Figure 11 , on the inner wall of each solution tank 30, a stirring roller 35 is rotatably arranged. A plurality of stirring blades 36 are fixed on the outer surface of the stirring roller 35. A driving box for cooperating with the stirring roller 35 is arranged on the outer side wall of the base side plate 1. The driving box for realizing the rotation of the stirring roller 35 is the prior art. On the inner wall of each solution tank 30 and near the position of the scraping plate 34, a linkage roller 37 is rotatably arranged. A plurality of protrusions 38 are fixed on the outer surface of the linkage roller 37. The central axes of each stirring roller 35 and the linkage roller 37 both rotatably penetrate through the base side plate 1 and are fixedly sleeved with linkage gear discs 39. A chain 40 is arranged in a transmission manner on adjacent two linkage gear discs 39.

[0056] Refer to Figure 4 , Figure 10 and Figure 11 , during the use process, the stirring roller 35 drives each stirring blade 36 to rotate, stirring the printing coatings in the solution tank 30 to avoid partial condensation of the printing coatings. During the rotation of the stirring roller 35, through the cooperation of the linkage gear disc 39 and the chain 40, the linkage roller 37 and each protrusion 38 are driven to rotate together. During the rotation of the protrusion 38, it will collide with the end of the scraping plate 34, causing the vibration of the scraping plate 34, thereby promoting the rapid dripping of the printing coatings adhered to the surface of the scraping plate 34 and avoiding the condensation of the printing coatings on the scraping plate 34.

[0057] When the present invention is in use, refer to Figure 1 and Figure 2 , when the variable printing layer two 45 is in a dry state, the variable printing layer two 45 is in a display state. The variable printing layer two 45 covers the surface of the anti-counterfeiting pattern two 44. The user cannot see the anti-counterfeiting pattern two 44 and can only see the anti-counterfeiting pattern one 43. When the variable printing layer two 45 is wiped with water, the variable printing layer two 45 is wetted. At this time, the variable printing layer two 45 is in a transparent state. The user can observe the anti-counterfeiting pattern two 44 through the variable printing layer two 45, which is convenient for verification;

[0058] Refer to Figure 3 and Figure 4, when the packaging bag body 41 is being produced and processed, the plastic film 46 is fed by the lower material guiding roller 2 and passes through the adjacent roller printing assemblies. Through the set roller printing assemblies, a first printing layer 42 is printed on the surface of the plastic film 46. The plastic film 46 that has undergone the first printing is fed by the upper material guiding roller 5 and passes through multiple rapid air drying assemblies. During this process, the first printing layer 42 printed on the surface of the plastic film 46 is quickly dried to avoid affecting the printing of the variable second printing layer 45. After the plastic film 46 passes through the rapid air drying assemblies, it is fed by the upper material guiding roller 7, and the plastic film 46 passes through the corresponding roller printing assemblies. During this process, the variable second printing layer 45 is printed, which is convenient to use;

[0059] Refer to Figures 3 - 7 , after the plastic film 46 is fed by the upper material guiding roller 5, the plastic film 46 passes between the receiving roller 9 and the corresponding pressing roller 11. Through the cooperation of the receiving roller 9 and the pressing roller 11, it is avoided that the plastic film 46 shakes greatly during the rapid air drying process, which affects the conveyance of the plastic film 46. And the mounting seats 10 on the same side are arranged at intervals to avoid too many mounting seats 10 affecting the flow of the air flow generated by the rapid air drying assemblies, further reducing the influence on the conveyance stability of the plastic film 46;

[0060] Refer to Figure 3 , Figure 5 , Figure 8 and Figure 9 , after the air flow is discharged from the end of the through ventilation groove 12, it passes through the moving cover 24. Under the guiding of the inclined surface of the moving cover 24, the air flow quickly passes through between the lower end surface of the moving cover 24 and the plastic film 46 (the area through which the air flow can pass decreases, and the flow rate increases), so as to quickly dry the first printing layer 42 on the surface of the plastic film 46. And during this process, each small exhaust fan 26 also works to guide the water vapor carried in the passing air flow upward, away from the plastic film 46;

[0061] Refer to Figure 4 and Figure 10 , the solution tank 30 is filled with the corresponding printing coating. The lower part of the slurry feeding roller 31 is immersed in the printing coating. The transfer roller 32 and the slurry feeding roller 31 rotate in cooperation to cause the corresponding position of the slurry feeding roller 31 to adhere to the printing coating. The transfer roller 32 and the auxiliary roller 33 rotate in cooperation to print the printing coating on the transfer roller 32 onto the plastic film 46;

[0062] Refer to Figure 4 , Figure 10 and Figure 11, during use, the stirring roller 35 drives each stirring blade 36 to rotate, agitating the printing coating in the solution tank 30 to prevent partial condensation of the printing coating. During the rotation of the stirring roller 35, through the cooperation of the linkage gear disk 39 and the chain 40, the linkage roller 37 and each protrusion 38 are driven to rotate together. During the rotation of the protrusion 38, it will collide with the end of the squeegee 34, causing vibration of the squeegee 34, thereby promoting the rapid dripping of the printing coating adhering to the surface of the squeegee 34 and preventing the printing coating from condensing on the squeegee 34.
