Description

Technical Field

[0001] This invention relates to the field of printing, specifically to a color box printing device and method with anti-cardboard function. Background Technology

[0002] Printing is a technology that transfers ink to the surface of a material by means of original manuscripts such as text, pictures, photos, and anti-counterfeiting materials through processes such as plate making, inking, and pressing. Paper packaging boxes are extremely common in daily life. Color boxes are paper boxes with colored patterns on their surface. Depending on the material, the processing methods are also different. At present, the main printing methods for color boxes include two types: printing directly on the cardboard and printing the face paper first and then combining the face paper with the cardboard.

[0003] In the direct printing method on cardboard, the cardboard may shift or warp during processing due to external environmental factors or equipment vibrations. This can cause the cardboard to jam when passing through the printing box, requiring machine shutdown for maintenance and reorganization. Furthermore, the shaking of the cardboard during printing may cause quality problems with the printed pattern, making it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a color box printing apparatus and method with anti-cardboard function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a color box printing apparatus with anti-cardboard-blocking function, comprising:

[0006] The printing machine base has a cardboard conveyor belt that slides horizontally on its upper end. The cardboard conveyor belt includes several suction conveyor plates and several multi-functional tube shafts. A printing box is located at the center of the printing machine base above the cardboard conveyor belt.

[0007] An adsorption assembly is disposed within an adsorption conveying plate and includes a collection groove and several adsorption holes.

[0008] An auxiliary combing assembly is located on one side of the printing press base. The auxiliary combing assembly includes a lower pressure roller and two guide plates.

[0009] The connecting components are located on both sides of the printing press base. Each connecting component includes a circulation sealing groove and a negative pressure suction groove. Several multi-functional tube shafts are movably inserted into two circulation sealing grooves on both sides.

[0010] Preferably, the adsorption conveying plate has a plurality of mating blocks symmetrically arranged on one side, and a plurality of mating grooves symmetrically opened on the side of the adsorption conveying plate away from the mating blocks. The plurality of mating blocks and the plurality of mating grooves are staggered, and the mating blocks and mating grooves of two adjacent adsorption conveying plates are respectively inserted and connected.

[0011] Preferably, a shaft groove is horizontally opened through one side of each of the several mating blocks and mating grooves, and several multifunctional tube shafts are respectively horizontally inserted into the shaft grooves at the joint of two adjacent adsorption conveying plates.

[0012] Preferably, each of the mating blocks of the adsorption conveying plate is provided with a transfer groove, and the multi-functional tube shaft is provided with several collection holes symmetrically connected on one side of the transfer groove. The mating block is fitted with the multi-functional tube shaft and is provided with sealing rings on both sides of the transfer groove.

[0013] Preferably, the adsorption conveying plate has a horizontally formed collection groove at its center, and a connecting groove is formed on one side of the collection groove and the transfer groove of the mating block. A number of adsorption holes are respectively formed on both sides of the upper end of the adsorption conveying plate, and the lower ends of the adsorption holes are respectively connected to the collection groove.

[0014] Preferably, a loading platform is horizontally provided on one side of the printing machine base, and two guide plates are respectively horizontally movable on both sides of the upper end of the loading platform via mounting shafts. The lower pressure roller is horizontally provided on the upper end of the printing machine base near the guide plates, and the upper end of the loading platform is flush with the upper end of the adsorption conveying plate.

[0015] Preferably, two suction control boxes are symmetrically arranged on both sides of the printing press base near the printing box. Two drive slots are opened on both sides of the printing press base. Several suction conveyor plates and several suction conveyor plates are movably inserted into the two drive slots on both sides. The multi-functional tube shaft is placed in the drive slot and a traction chain is provided on one side.

[0016] Preferably, the multifunctional tube shaft is provided with auxiliary rollers on the side of the drive groove near the driving chain, and one side of the auxiliary rollers is in contact with one side of the drive groove.

[0017] Preferably, a negative pressure suction groove is provided on the side of the printing press base near the suction control box, and a circulation sealing groove is provided on the side of the drive groove near the multi-functional tube shaft along the movement trajectory of the cardboard conveyor belt. A circulation sealing strip is movably inserted into the circulation sealing groove, and one side of the circulation sealing strip is sleeved with one side of several multi-functional tube shafts. Each circulation sealing strip on the side of the multi-functional tube shaft has a connecting hole. One side of the negative pressure suction groove is connected to the circulation sealing groove and has a suction window. The multi-functional tube shaft is connected to the negative pressure suction groove through the connecting hole of the circulation sealing strip.

[0018] A method of using a color box printing apparatus with anti-card jamming function, wherein the method of using the color box printing apparatus with anti-card jamming function is applied to the aforementioned color box printing apparatus with anti-card jamming function, includes the following steps:

[0019] Step 1: The cardboard to be printed is placed on the upper part of the loading platform in sequence by the suction cup feeding device. Under the gathering and positioning action of the guide plate, the cardboard is positioned. Then, the cardboard is pressed by the lower pressure roller to stick to the upper part of several suction conveyor plates.

[0020] Step 2: The cardboard conveyor belt drives several traction chains to rotate in a cycle via sprockets, thereby moving several suction conveyor plates and pulling the cardboard to the bottom of the printing box for digital printing.

[0021] Step 3: After the cardboard passes through the lower pressure roller, the multi-functional tube shaft on one side of the adsorption conveyor plate located at the lower pressure roller position is connected to the suction window and the negative pressure suction groove through the circulation sealing strip. At this time, the suction control box performs negative pressure suction on the negative pressure suction groove. Due to the sealing of the suction window by the circulation sealing groove, the gas for negative pressure suction needs to be provided from the multi-functional tube shaft. At this time, the gas in the collection groove is drawn by the multi-functional tube shaft through the connecting groove and the collection hole, thereby changing the air pressure above several adsorption holes, stabilizing the cardboard and the adsorption conveyor plate, and keeping the cardboard flat and stable.

[0022] Step 4: After the cardboard is printed in the printing box, the multi-functional tube shaft and the suction window are misaligned. At this time, the suction force of the suction window acts on the suction conveyor plate behind it, and the cardboard can automatically enter the next process as the cardboard conveyor belt rotates.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] A cardboard conveyor belt with adsorption function is set at the upper part of the printing press base, consisting of several adsorption conveying plates and a multi-functional tube shaft. During the cardboard conveying and printing process, the cardboard is leveled and positioned to avoid cardboard movement or deformation that could cause jamming. With the cooperation of the connecting components and the adsorption, the cardboard is automatically adsorbed and released. The operation is simple and convenient, and it can effectively improve the printing efficiency and printing quality of the cardboard. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 The present invention provides the following technical solutions:

[0038] Example 1

[0039] A color box printing device with anti-cardboard jamming function includes a printing machine base 1. A cardboard conveyor belt 2 is horizontally slidably mounted on the upper end of the printing machine base 1. The cardboard conveyor belt 2 includes several suction conveyor plates 7 and several multi-functional tube shafts 10. A printing box 6 is located at the center above the cardboard conveyor belt 2 on the printing machine base 1. Several mating blocks 8 are symmetrically arranged on one side of the suction conveyor plates 7. Several mating grooves 9 are symmetrically opened on the side of the suction conveyor plates 7 away from the mating blocks 8. The several mating blocks 8 and several mating grooves 9 are staggered. The mating blocks 8 and mating grooves 9 of two adjacent suction conveyor plates 7 are respectively inserted and connected. A shaft groove is horizontally opened through one side of each of the several mating blocks 8 and mating grooves 9. Several multi-functional tube shafts 10 are respectively horizontally inserted into the shaft grooves at the joint of two adjacent suction conveyor plates 7. The suction conveyor plates 7 are rigid structures. When the cardboard conveyor belt 2 rotates in a cycle, the two suction conveyor plates 7 are hinged by the multi-functional tube shafts 10, and the two suction conveyor plates 7 are tightly fitted together.

[0040] An adsorption assembly is set up to adsorb the cardboard above the adsorption conveyor plate 7. The adsorption assembly is located inside the adsorption conveyor plate 7 and includes a collection groove 13 and several adsorption holes 15. A transfer groove 11 is opened in the mating block 8 of the adsorption conveyor plate 7. Several collection holes 12 are symmetrically opened on one side of the multi-functional tube shaft 10 located in the transfer groove 11. The mating block 8 is sleeved on the multi-functional tube shaft 10 and is provided with sealing rings on both sides of the transfer groove 11. Wear-resistant sealing sleeves are set at the position of the mating block 8 and the multi-functional tube shaft 10 to improve the air absorption efficiency of the multi-functional tube shaft 10.

[0041] A collection groove 13 is horizontally opened in the center of the adsorption conveying plate 7. A connecting groove 14 is opened on one side of the collection groove 13 and the transfer groove 11 of the mating block 8. Several adsorption holes 15 are respectively opened on both sides of the upper end of the adsorption conveying plate 7, and the lower ends of the several adsorption holes 15 are respectively connected to the collection groove 13. When air is drawn into the collection groove 13, the air pressure outside the adsorption holes 15 changes, which will compress the cardboard to make stable contact with the adsorption conveying plate 7, reduce the cardboard from warping and causing cardboard to be stuck, and improve the efficiency of printing quality.

[0042] In this embodiment, when negative pressure suction occurs inside the multifunctional tube shaft 10, the transfer groove 11, collection hole 12, connecting groove 14 and collection groove 13 can perform negative pressure suction on several adsorption holes 15. At this time, the cardboard is in contact with the upper end of the adsorption conveyor plate 7. With the help of the negative pressure suction below, the cardboard can be flattened and adsorbed, avoiding the edges of the cardboard from lifting or moving and getting stuck with the equipment. The rigid structure adsorption conveyor plate 7 is structurally stable when adsorbing the cardboard, and the flatness of the cardboard can also improve the quality of the printed pattern.

[0043] Example 2

[0044] Based on Embodiment 1, a connecting component is set up to automatically adsorb cardboard when adsorption is required. The connecting component is located on both sides of the printing machine base 1. Each connecting component includes a circulation sealing groove 19 and a negative pressure suction groove 20. The two sides of several multi-functional tube shafts 10 are respectively movably inserted into the two circulation sealing grooves 19. Two suction control boxes 25 are symmetrically arranged on both sides of the printing machine base 1 near the printing box 6. Two drive grooves 16 are opened on both sides of the printing machine base 1. The two sides of several adsorption conveyor plates 7 are respectively movably inserted into the two drive grooves 16. The side of the multi-functional tube shaft 10 placed in the drive groove 16 is provided with a traction chain 17. The side of the multi-functional tube shaft 10 placed in the drive groove 16 near the traction chain 17 is movably sleeved with an auxiliary roller 18. The side of the auxiliary roller 18 is in contact with the side of the drive groove 16. When the cardboard conveyor belt 2 is driven by the traction chain 17, the auxiliary roller 18 can stabilize the position and posture of the adsorption conveyor plate 7.

[0045] Negative pressure suction grooves 20 are provided on one side of the printing press base 1 near the suction control box 25. A circulation sealing groove 19 is provided on one side of the drive groove 16 near the multi-functional tube shaft 10 along the movement trajectory of the cardboard conveyor belt 2. A circulation sealing strip 22 is movably inserted into the circulation sealing groove 19. Several multi-functional tube shafts 10 are sleeved on one side of the circulation sealing strip 22. Each circulation sealing strip 22 has a connecting hole 23 on one side of the multi-functional tube shaft 10. A suction window 21 is provided on one side of the negative pressure suction groove 20 connected to the circulation sealing groove 19. The multi-functional tube shaft 10 is connected to the negative pressure suction groove 20 through the connecting hole 23 of the circulation sealing strip 22. The cardboard is flattened and adsorbed before entering the printing box 6 for printing. The adsorption can be automatically released after printing.

[0046] In this embodiment, as the cardboard conveyor belt 2 rotates cyclically, several multi-functional tube shafts 10 drive the circulating sealing strips 22 to rotate cyclically along the track within the circulating sealing groove 19. The circulating sealing strips 22 always block the position of the suction window 21. The adsorption force applied in the negative pressure suction groove 20 can only be transmitted to the corresponding adsorption conveyor plate 7 through the connecting hole 23 and the multi-functional tube shafts 10. This achieves the flattening and fixing of the cardboard before printing in the printing box 6, avoiding the problem of cardboard warping or moving before entering the printing box 6 and improving the printing quality.

[0047] Example 3

[0048] Based on Embodiment 2, an auxiliary combing component is set up to feed and comb the cardboard to be printed. The auxiliary combing component is located on one side of the printing machine base 1. The auxiliary combing component includes a lower pressure roller 5 and two guide plates 4. A feeding platform 3 is horizontally provided on one side of the printing machine base 1. The two guide plates 4 are respectively horizontally movable on both sides of the upper end of the feeding platform 3 through the mounting shaft. The lower pressure roller 5 is horizontally provided on the side of the upper end of the printing machine base 1 close to the guide plates 4, and the upper end of the feeding platform 3 is flush with the upper end of the adsorption conveyor plate 7. The cardboard combed by the two guide plates 4 is located in the center of the cardboard conveyor belt 2, which facilitates accurate subsequent printing. After being pressed down by the lower pressure roller 5, the cardboard is stably attached to the adsorption conveyor plate 7. At this time, when the adsorption conveyor plate 7 generates adsorption force, the cardboard can be directly and stably attached to the adsorption conveyor plate 7 without subsequent movement.

[0049] In addition, when the width of the cardboard is less than the width of the adsorption conveyor plate 7, sealing stickers can be affixed above several adsorption holes 15 on both sides of the adsorption conveyor plate 7 to make the adsorption force at the adsorption holes 15 where the adsorption conveyor plate 7 contacts the cardboard stronger, thereby reducing the energy consumption of the negative pressure equipment.

[0050] A method of using a color box printing device with anti-cardboard-blocking function includes the following steps:

[0051] Step 1: The cardboard to be printed is placed on the upper end of the loading table 3 by the suction cup feeding device. The cardboard is positioned by the gathering and positioning action of the guide plate 4. Then, the cardboard is pressed by the lower pressure roller 5 to stick to the upper end of several suction conveyor plates 7.

[0052] Step 2: The cardboard conveyor belt 2 drives several traction chains 17 to rotate in a cycle through the sprocket, thereby moving several adsorption conveyor plates 7 and pulling the cardboard to the bottom of the printing box 6 for digital printing operation.

[0053] Step 3: After the cardboard passes through the lower pressure roller 5, the multi-functional tube shaft 10 located on one side of the adsorption conveying plate 7 at the position of the lower pressure roller 5 is connected to the suction window 21 and the negative pressure suction groove 20 through the circulation sealing strip 22. At this time, the suction control box 25 performs negative pressure suction on the negative pressure suction groove 20. Due to the sealing of the suction window 21 by the circulation sealing groove 19, the gas for negative pressure suction needs to be provided from the multi-functional tube shaft 10. At this time, the gas in the collection groove 13 is drawn by the multi-functional tube shaft 10 through the connecting groove 14 and the collection hole 12. As a result, the air pressure above several adsorption holes 15 changes, which stably adsorbs the cardboard to the adsorption conveying plate 7, keeping the cardboard flat and stable.

[0054] Step 4: After the cardboard is printed by the printing box 6, the multi-functional tube shaft 10 and the suction window 21 are misaligned. At this time, the suction force of the suction window 21 acts on the suction conveyor plate 7 behind it. The cardboard can then enter the next process by itself as the cardboard conveyor belt 2 rotates.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
