Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and in particular to a fully automatic high-speed continuous line printing process and equipment. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images, either manually or by the printing press itself. The ink is then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate.

[0003] However, in actual use, the inventors found that the equipment caused heat accumulation during long-term high-speed transport of the printing substrate, which led to thermal expansion of the rollers. The printing substrate was squeezed and broke, making it difficult to reconnect. Manual assistance was required to re-pull the printing substrate, resulting in discontinuity in the printing and rewinding process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a fully automatic high-speed continuous printing line process and equipment. This system can quickly and automatically reconnect two broken ends of the substrate without manual assistance or replacement of the substrate roll, ensuring the continuity of substrate transport and improving printing efficiency. This solves the technical problem of heat accumulation during long-term high-speed substrate transport, which causes roller thermal expansion, substrate breakage due to compression, and necessitates manual retraction, leading to discontinuous printing and rewinding.

[0005] To address the above technical issues, the following technical solution is adopted: A fully automatic high-speed continuous printing line includes a printing mechanism and a power transmission mechanism disposed in front of the printing mechanism. The power transmission mechanism includes a roller conveying assembly, a cooling assembly disposed on the roller conveying assembly, edge trimming assemblies disposed on both sides of the roller conveying assembly, and a connecting assembly disposed on one side of the roller conveying assembly. After the roller conveyor breaks the substrate, it rises to the position of the cooling component, which cools and cleans it. Meanwhile, the edge trimming component trims the two broken ends of the substrate, and the rejoining component glues the two broken ends together and polishes and irons the seam. After the substrate is rejoined, the roller conveyor descends and continues to transport the substrate forward.

[0006] Preferably, the roller conveying assembly includes: The platform is mounted on a rack and has an organic cover. A movable roller is mounted inside the machine housing via a track, and the rotating roller is used to convey the printing substrate on the platform forward. An infrared sensor is installed inside the machine housing and is used to monitor the breakage of the printing substrate in real time.

[0007] Preferably, the cooling assembly includes: The semi-circular hollow clamps are horizontally movable inside the machine cover. The two sets of semi-circular hollow clamps are connected to fit the outer wall of the moving roller. An arc-shaped heat exchange plate is provided on the inner circular wall of the semi-circular hollow clamps, and a water circulation interface is provided on the outer circular wall of the semi-circular hollow clamps. Two sets of chip collection boxes are symmetrically arranged on both sides of the semi-circular hollow clamp.

[0008] Preferably, the cooling assembly further includes: The fan is mounted on top of the casing; A water tank is located on the top of the machine cover and is connected to a water circulation interface on a semi-circular hollow clamp via a hose.

One set of the trimming units is disposed inside the machine housing, and the indentation units on the trimming units are used to indent the upper surface of one substrate joint. Another set of the trimming units is disposed inside the waste bin, and the indentation units on the trimming units are used to indent the lower surface of another substrate joint. The cutting unit first fixes the two broken ends of the substrate, and then cuts the broken ends of the substrate evenly. The indentation unit presses out protrusions with interlocking teeth at the two joints of the substrate.

[0010] Preferably, the cutting edge unit includes: The pressure plate, two sets of the pressure plates are symmetrically arranged and raised and lowered inside the machine cover, and the pressure plate is used to fix the broken printing substrate; The two sets of hangers are synchronously raised, lowered, and laterally positioned inside the machine cover; A cutting wheel, which is rotatably mounted on the hanger, is used to cut the broken ends of the substrate.

[0011] Preferably, the indentation unit includes: An indentation wheel is mounted on the cutting wheel and rotates coaxially with the cutting wheel. Several sets of forming blocks are evenly arranged on the indentation wheel along the circumferential direction. A glue-applying wheel is rotatably mounted on the hanger and is used to apply glue to the joint indentation of the substrate.

[0012] Preferably, the splicing assembly includes a traction unit disposed inside the machine housing and a crimping unit disposed inside the machine housing; The traction unit pulls one indented substrate joint to another indented substrate joint, and the crimping unit presses the two indented substrate joints together and then sands and irons the seam. The traction unit includes: Two sets of electric grippers are horizontally movable and symmetrically arranged inside the machine cover, and are used to grip and move a substrate connector.

[0013] Preferably, the crimping unit includes: L-shaped horizontal plate, which is lifted and moved horizontally inside the machine cover; A bracket is slidably mounted on the L-shaped horizontal plate, and an elastic element is provided between the bracket and the L-shaped horizontal plate; An extension rod is mounted on the bracket, and a limiting track is provided inside the machine cover. The limiting track is used to drive the extension rod to move the bracket horizontally. The support is rotatably mounted with a pressure roller, a grinding roller, and an electric heating roller.

[0014] As a preferred embodiment, a fully automated high-speed continuous printing process includes the following steps: Step 1, conveying process: The power transmission mechanism quickly conveys the substrate to the printing mechanism and monitors the breakage of the substrate in real time. If the substrate breaks, the broken part of the substrate is dealt with in time, the broken part of the substrate is reconnected, and then the substrate is conveyed forward again. Step two, the printing process, the printing mechanism prints on the substrate. When the substrate breaks at the power transmission mechanism, the printing mechanism receives information in real time and stops printing in time. After the broken part of the substrate is repaired, the printing mechanism continues printing. Step three, the drying process, involves drying the printed substrate to quickly dry the ink on it, and finally rolling up the substrate.

[0015] The beneficial effects of this invention are: (1) In this invention, by setting the edge trimming component and the connecting component together, on the one hand, it can quickly and automatically connect the two broken ends of the substrate without manual assistance or replacement of the substrate roll, thus ensuring the continuity of substrate transport and improving the printing efficiency of the substrate; on the other hand, it can automatically trim the broken ends of the substrate and bond the two joints of the substrate by pulling, thereby improving the tensile strength of the substrate joint, ensuring the firmness of the joint, avoiding the joint from separating again during the transport of the substrate, and automatically polishing and beautifying the joint, weakening the impact of the joint on the pattern on the substrate, thus ensuring the integrity of the pattern on the substrate.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1 like Figures 1-16 As shown, a fully automatic high-speed continuous printing line includes a printing mechanism 2 and a power transmission mechanism 1 located in front of the printing mechanism 2, which rapidly transports the substrate to the printing mechanism 2. The power transmission mechanism 1 includes a roller conveying assembly 11, a cooling assembly 12 disposed on the roller conveying assembly 11, an edge trimming assembly 13 disposed on both sides of the roller conveying assembly 11, and a connecting assembly 14 disposed on one side of the roller conveying assembly 11. After the roller conveying assembly 11 breaks the substrate, the roller conveying assembly 11 rises to the position of the cooling assembly 12. The cooling assembly 12 cools and cleans the roller conveying assembly 11. At the same time, the edge trimming assembly 13 trims the two broken ends of the substrate, and the reconnection assembly 14 bonds the two broken ends of the substrate and polishes and irons the seam. After the substrate reconnection is completed, the roller conveying assembly 11 descends and continues to convey the substrate forward.

[0037] It should be noted that the structure and function of printing mechanism 2 are existing technologies and will not be described in detail here.

[0038] In this embodiment, the edge trimming component 13 and the reconnection component 14 work together to: on the one hand, quickly and automatically reconnect the two broken ends of the substrate without manual assistance or replacement of the substrate roll, ensuring the continuity of substrate transport and improving printing efficiency; on the other hand, automatically trimming the broken ends of the substrate and bonding the two joints of the substrate by pulling them together, improving the tensile strength of the joint and ensuring its firmness, preventing the joint from separating again during substrate transport, and automatically polishing and beautifying the joint, weakening its impact on the pattern on the substrate and ensuring the integrity of the pattern on the substrate.

[0039] In detail, the roller conveyor assembly 11 rapidly transports the substrate to the printing mechanism 2 for printing. When the roller conveyor assembly 11 thermally expands and breaks the substrate, the printing mechanism 2 stops working, and the roller conveyor assembly 11 rises to the position of the cooling assembly 12. The cooling assembly 12 cools and cleans the roller conveyor assembly 11. At the same time, the edge trimming assembly 13 trims the two broken ends of the substrate, and the splicing assembly 14 bonds the two broken ends of the substrate and polishes and irons the seam. After the substrate splicing is completed, the roller conveyor assembly 11 descends and continues to transport the substrate forward.

[0040] Furthermore, such as Figures 1-5 As shown, the roller conveying assembly 11 includes: Platform 111, which is mounted on rack 3; A machine cover 112 is disposed on the platform 111; The movable roller 113 is mounted inside the machine cover 112 via a track. The movable roller 113 rotates to convey the printing substrate on the platform 111 forward. A linear motor of the prior art is mounted on the track to drive the movable roller 113 to move up and down. A rotary motor is embedded in one end of the movable roller 113 to drive the movable roller 113 to rotate to convey the printing substrate. Infrared sensor 114 is disposed inside the machine cover 112 and is used to monitor the breakage of the printing substrate in real time. The structure and function of infrared sensor 114 are existing technologies and will not be described in detail here.

[0041] It should be noted that the structure and function of the infrared sensor 114 are existing technologies and will not be described in detail here.

[0042] In this embodiment, the roller conveying assembly 11 and the printing mechanism 2 work together to automatically and quickly transport the substrate to the printing mechanism 2 for printing, and monitor the breakage of the substrate in real time. When the substrate breaks, information is transmitted in time to control the printing mechanism 2 to stop printing.

[0043] In detail, the moving roller 113, driven by a rotary motor, conveys the substrate on the platform 111 forward. When the infrared sensor 114 detects that the substrate at the moving roller 113 is broken, it transmits information to control the printing mechanism 2 to stop printing.

[0044] Furthermore, such as Figures 2-9 As shown, the cooling assembly 12 includes: The first horizontal drive unit 121, two sets of the first horizontal drive units 121 are arranged inside the machine cover 112 and symmetrically located on both sides of the moving roller 113; A lifting block is provided at the output end of the first horizontal drive unit 121, and a first hydraulic component 122 is provided on the lifting block; A semi-circular hollow clamp 123 is provided at the output end of the first hydraulic component 122. Two sets of the semi-circular hollow clamps 123 are connected to fit the outer wall of the moving roller 113. An arc-shaped heat exchange plate 124 is provided on the inner circular wall of the semi-circular hollow clamp 123, and a water circulation interface 125 is provided on the outer circular wall of the semi-circular hollow clamp 123. The chip collection box 126, two sets of the chip collection boxes 126 are symmetrically arranged on both sides of the semi-circular hollow clamp 123, and are used to collect foreign objects on the outer wall of the moving roller 113; Fan 127 is disposed on the top of the machine cover 112 and is used to cool the moving roller 113 by air. Water tank 128 is located on the top of the machine cover 112 and is connected to the water circulation interface 125 on the semi-circular hollow clamp 123 via a hose, for water cooling of the moving roller 113.

[0045] It should be noted that the first horizontal drive unit 121, the second horizontal drive unit 1313, the third horizontal drive unit 1411 and the fourth horizontal drive unit 1421 have the same structure, all consisting of a lead screw, a threaded block threaded on the lead screw and a stepper motor that drives the lead screw to rotate.

[0046] In this embodiment, the cooling component 12 can, on the one hand, quickly cool the moving roller 113 through a two-stage cooling method of water cooling and air cooling, preventing the moving roller 113 from breaking the substrate again, saving the cooling time of the moving roller 113, and accelerating the printing efficiency of the substrate; on the other hand, it can automatically clean the foreign matter adhering to the moving roller 113 due to high temperature during the cooling process, improve the cleanliness of the surface of the moving roller 113, and prevent foreign matter on the moving roller 113 from affecting the conveyed substrate.

[0047] In detail, when the infrared sensor 114 detects that the substrate at the moving roller 113 is broken, it transmits information to control the printing mechanism 2 to stop printing. The linear motor of the prior art drives the moving roller 113 to rise to the position of the semi-circular hollow clamp 123. The first hydraulic component 122 drives the two semi-circular hollow clamps 123 to engage and close on the moving roller 113. The first horizontal drive unit 121 drives the two semi-circular hollow clamps 123 to move slowly along the axis of the moving roller 113. The cold water in the water tank 128 enters the semi-circular hollow clamp 123 through the water circulation interface 125. The heat on the moving roller 113 is transferred to the cold water in the semi-circular hollow clamp 123 through the arc-shaped heat exchange plate 124, which quickly cools the moving roller 113. At the same time, the arc-shaped heat exchange plate 124 scrapes off foreign objects on the surface of the moving roller 113. The foreign objects fall into the chip collection box 126 and are cleaned periodically. Meanwhile, the fan 127 blows cold water on the moving roller 113 to further accelerate the cooling of the moving roller 113.

[0048] Furthermore, such as Figures 3-12 As shown, the edge trimming assembly 13 includes two sets of edge trimming units 131, an indentation unit 132 disposed on the edge trimming unit 131, two sets of material drop ports 1317 symmetrically opened on the platform 111, and a waste bin 1318 disposed at the bottom of the platform 111. One set of the trimming units 131 is disposed inside the machine cover, and the indentation unit 132 on the trimming unit 131 is used to indent the upper surface of one substrate joint. Another set of the trimming units 131 is disposed inside the waste bin 1318, and the indentation unit 132 on the trimming unit 131 is used to indent the lower surface of another substrate joint. The cutting unit 131 first fixes the two broken ends of the substrate, and then cuts the broken ends of the substrate evenly. The indentation unit 132 presses out protrusions with interlocking teeth and pulling against each other at the two joints of the substrate. The cutting unit 131 includes: The second hydraulic component 1311, two sets of the second hydraulic components 1311 are symmetrically arranged inside the machine cover 112. The output end of the second hydraulic component 1311 is provided with a pressure plate 1312, which is used to fix the broken printing substrate. It should be noted that one set of pressure plates 1312 descends onto the platform 111 and is located on one side of the material discharge port 1317, so that the indentation unit 132 on the edge trimming unit 131 inside the machine cover 112 can indent the upper surface of one substrate joint. Another set of pressure plates 1312 descends onto the platform 111 and is located above the material discharge port 1317, bearing the upward pressure of the indentation wheel 1321 on the substrate, so that the indentation unit 132 on the edge trimming unit 131 inside the waste bin 1318 can indent the lower surface of another substrate joint. The second horizontal drive unit 1313, two sets of the second horizontal drive units 1313 are disposed inside the housing 112; The third hydraulic component 1314 is disposed at the output end of the second horizontal drive unit 1313, and a hanger 1315 is disposed at the output end of the third hydraulic component 1314. A cutting wheel 1316 is rotatably mounted on the hanger 1315 and is used to cut the broken ends of the printing substrate. The indentation unit 132 includes: The embossing wheel 1321 is disposed on the cutting wheel 1316 and rotates coaxially with the cutting wheel 1316. Several sets of forming blocks 1322 are evenly arranged on the embossing wheel 1321 along the circumferential direction. The glue-applying wheel 1323 is rotatably mounted on the hanger 1315 and is used to apply glue to the joint indentation of the substrate. The glue box 1324 is disposed on the hanger 1315 and is used to replenish glue to the glue application wheel 1323.

[0049] It is worth mentioning that the height of the joint of the embossing roller 1321 pressing down on the substrate is one-quarter of the thickness of the substrate, and the height of the joint of the embossing block 1322 pressing down on the substrate is three-quarters of the thickness of the substrate, which facilitates the horizontal alignment of the joints of the two substrates.

[0050] In this embodiment, by using the cutting unit 131 and the indentation unit 132 together, the joint of the substrate can be cleaned and the bonding of the substrate can be completed, thereby improving the tensile strength of the joint.

[0051] In detail, when the infrared sensor 114 detects a breakage of the substrate at the moving roller 113, it transmits information to control the printing mechanism 2 to stop printing. The second hydraulic component 1311 drives the pressure plates 1312 to descend. One set of pressure plates 1312 descends onto the platform 111 and is located on one side of the material discharge port 1317, while the other set of pressure plates 1312 descends onto the platform 111 and is located above the material discharge port 1317. Then, the third hydraulic component 1314 drives the hanger 1315 to rise and fall with the cutting roller 1316. One cutting roller 1316 descends to... At the edge of the material outlet 1317, another cutting wheel 1316 rises to the edge of the pressure plate 1312. The second horizontal drive unit 1313 drives the cutting wheel 1316 to move horizontally, so that one indentation wheel 1321 rolls on the platform at the edge of the material outlet 1317, and the other indentation wheel 1321 rolls on the bottom of the pressure plate 1312. The cutting wheel 1316 cuts off the broken head of the substrate, and the indentation wheel 1321 presses out the anti-pull protrusion at the joint of the substrate. At the same time, the glue application wheel 1323 applies glue to the indentation at the joint of the substrate.

[0052] Furthermore, such as Figures 10-16 As shown, the connecting assembly 14 includes a traction unit 141 disposed inside the housing 112 and a crimping unit 142 disposed inside the housing 112. The traction unit 141 pulls one indented substrate joint to another indented substrate joint, and the crimping unit 142 presses the two indented substrate joints together and grinds and irons the joint. The traction unit 141 includes: The third horizontal drive unit 1411, two sets of the third horizontal drive units 1411 are symmetrically arranged inside the machine cover 112; The fourth hydraulic component 1412 is disposed at the output end of the third horizontal drive unit 1411; An electric gripper 1413 is disposed at the output end of the fourth hydraulic component 1412.

[0053] It should be noted that the electric gripper 1413 is existing technology and will not be described in detail here.

[0054] In this embodiment, the traction unit 141 can automatically pull the joint of one substrate to the joint of another substrate, which facilitates the bonding of the joints of the two substrates.

[0055] In detail, after the edge trimming assembly 13 completes its work and resets, the fourth hydraulic component 1412 drives the electric gripper 1413 to hold the two ends of the connector of one substrate, and the third horizontal drive unit 1411 drives the electric gripper 1413 to move the connector of one substrate to the connector of another substrate.

[0056] Furthermore, such as Figures 10-16 As shown, the crimping unit 142 includes: The fourth horizontal drive unit 1421 is disposed inside the housing 112; The fifth hydraulic component 1422 is disposed at the output end of the fourth horizontal drive unit 1421; L-shaped horizontal plate 1423, wherein the L-shaped horizontal plate 1423 is disposed on the output end of the fifth hydraulic component 1422; A bracket 1424 is slidably mounted on the L-shaped horizontal plate 1423, and an elastic element 1425 is provided between the bracket 1424 and the L-shaped horizontal plate 1423. An extension rod 1426 is mounted on the bracket 1424. A limiting track 1427 is provided inside the cover 112. The limiting track 1427 is used to drive the extension rod 1426 to move the bracket 1424 horizontally. Pressure roller 1428 is rotatably mounted on the bracket 1424 and is used to press the joints of two printing substrates together. A grinding wheel 1429 is rotatably mounted on the bracket 1424 and is used to grind the seam between the two substrates. A drive motor is mounted on the bracket 1424 to drive the grinding wheel 1429 to rotate. The heating wheel 14291 is rotatably mounted on the bracket 1424 and is used to iron the seam between the two printing substrates.

[0057] In this embodiment, the crimping unit 142 can press and bond the joint between two substrates, beautify the seam, and weaken the impact of the seam on the pattern on the substrate.

[0058] In detail, after the traction unit 141 completes its work and resets, the fifth hydraulic component 1422 drives the L-shaped horizontal plate 1423 to descend with the pressure roller 1428. The limit rail 1427 drives the extension rod 1426 to move the bracket 1424 horizontally, so that the bracket 1424 moves with the pressure roller 1428 to the seam of the two substrates. The fourth horizontal drive unit 1421 drives the pressure roller 1428 to move horizontally, so that the pressure roller 1428 presses and adheres to the joint of the two substrates, so that the protrusions at the joint of the two substrates pull against each other. The drive motor drives the grinding wheel 1429 to grind the burrs at the joint. The electric heating wheel 14291 heats and irons the joint flat. Finally, the pressing unit 142 resets, the moving roller 113 descends and resets, and continues to drive the substrate forward to the printing mechanism 2 for printing.

For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 17 As shown, a fully automated high-speed continuous printing line process includes the following steps: Step 1, conveying process: the power transmission mechanism 1 quickly conveys the substrate to the printing mechanism 2 and monitors the breakage of the substrate in real time. If the substrate breaks, the broken part of the substrate is dealt with in time, the broken part of the substrate is reconnected, and then the substrate is conveyed forward again. Step 2, printing process: Printing mechanism 2 prints on the substrate. When the substrate breaks at the power transmission mechanism 1, printing mechanism 2 receives information in real time and stops printing in time. After the broken part of the substrate is reconnected, printing mechanism 2 continues printing. Step three, the drying process, involves drying the printed substrate to quickly dry the ink on it, and finally rolling up the substrate.

The two sets of hanging brackets are synchronously raised, lowered, and laterally moved inside the machine housing; and A cutting wheel, which is rotatably mounted on the hanger and is used to cut the broken ends of the substrate; The indentation unit includes: An indentation wheel is mounted on the cutting wheel and rotates coaxially with the cutting wheel. Several sets of forming blocks are evenly arranged on the indentation wheel along the circumferential direction. A glue-applying wheel, which is rotatably mounted on the hanger, is used to apply glue to the joint indentation of the substrate. One set of pressure plates descends onto the platform and is located on one side of the material discharge port, facilitating the indentation unit on a set of trimming units inside the machine housing to indent the upper surface of a substrate joint. Another set of pressure plates descends onto the platform and is located above the material discharge port, bearing the upward pressure of the indentation rollers on the substrate, facilitating the indentation unit on another set of trimming units inside the waste bin to indent the lower surface of another substrate joint. The splicing assembly includes a traction unit disposed inside the machine housing and a crimping unit disposed inside the machine housing. The traction unit pulls one embossed substrate joint to another embossed substrate joint, and the crimping unit presses the two embossed substrate joints together and then sands and irons the seam.

The limiting track is used to drive the extension rod to move the bracket horizontally. The support is rotatably mounted with a pressure roller, a grinding roller, and an electric heating roller.

5. A fully automatic high-speed continuous printing line process, applied to a fully automatic high-speed continuous printing line equipment as described in any one of claims 1-4, characterized in that, Includes the following steps: Step 1, conveying process: The power transmission mechanism quickly conveys the substrate to the printing mechanism and monitors the breakage of the substrate in real time. If the substrate breaks, the broken part of the substrate is dealt with in time, the broken part of the substrate is reconnected, and then the substrate is conveyed forward again. Step two, the printing process, the printing mechanism prints on the substrate. When the substrate breaks at the power transmission mechanism, the printing mechanism receives information in real time and stops printing in time. After the broken part of the substrate is repaired, the printing mechanism continues printing. Step three, the drying process, involves drying the printed substrate to quickly dry the ink on it, and finally rolling up the substrate.
