DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0041] The following describes the specific implementation of this application in more detail with reference to specific embodiments:

[0042] See also Figure 1 、 Figure 4 、 Figure 5The embodiment of the present application provides a high-speed, precise, fully automatic roller printing machine for MLCC, hereinafter referred to as the "roller printing machine", which includes a reeling mechanism 10, a printing mechanism 20, a reeling mechanism 30, a dustproof box 40, and a first boosting mechanism 50, and is particularly suitable for producing high-quality chip capacitors by the roller printing machine.

[0043] Among them, the unwinding mechanism 10, the printing mechanism 20 and the winding mechanism 30 are arranged in sequence and are all arranged in the dustproof box 40. The unwinding mechanism 10 is used to unwind the material tape toward the winding mechanism 30, the printing mechanism 20 is used to print the slurry onto the material tape, and the winding mechanism 30 is used to wind up the material tape. The first boosting mechanism 50 is arranged on the outside of the dustproof box 40 and is connected to the internal space of the dustproof box 40. The first boosting mechanism 50 is used to increase the air pressure in the dustproof box 40 so that the air pressure in the dustproof box 40 is greater than the external air pressure.

[0044] Based on this, by arranging the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 in sequence, and then unwinding the material tape from the unwinding mechanism 10 to the rewinding mechanism 30, the printing mechanism 20 prints the slurry onto the material tape, and the rewinding mechanism 30 rewinds the material tape, the roller printing machine can be used for automated production of products, effectively ensuring the performance of the roller printing machine.

[0045] By adopting the above scheme, the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 are all arranged in the dustproof box 40, so that the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 are protected and guarded by the dustproof box 40, so as to preliminarily reduce the risk of external dust and other impurities entering the dustproof box 40 and affecting the production quality of the roller printing machine, so as to preliminarily improve the dustproof performance of the roller printing machine. At the same time, by arranging a first boosting mechanism 50 on the outside of the dustproof box 40, the air pressure in the dustproof box 40 is increased by the first boosting mechanism 50, so that the air pressure in the dustproof box 40 is greater than the external air pressure, which can effectively reduce the dust and other impurities. The risk of external dust and other impurities entering the dustproof box 40 along with the external air is further reduced, so as to further reduce the risk of external dust and other impurities entering the dustproof box 40 and affecting the production quality of the roller printing machine, so as to further improve the dustproof performance of the roller printing machine. In this way, through the double protection of the dustproof box 40 and the first boosting mechanism 50, the environment in the dustproof box 40 can reach the standard of a dust-free workshop above Class 1000, effectively ensuring and improving the dustproof performance of the roller printing machine. Furthermore, the roller printing machine can produce high-quality products even in a dust-free workshop below Class 1000, effectively increasing the scope of use and application scenarios of the roller printing machine, and effectively ensuring and improving the performance of the roller printing machine.

[0046] In summary, the MLCC high-speed precision fully automatic roller printing machine provided by the embodiment of the present application, by sequentially arranging the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 and all being arranged in the dustproof box 40, while ensuring the performance of the roller printing machine, the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 can also be protected and protected by the dustproof box 40 to preliminarily improve the dustproof performance of the roller printing machine. At the same time, by arranging a first boosting mechanism 50 on the outside of the dustproof box 40, the air pressure in the dustproof box 40 can be increased by the first boosting mechanism 50, so that the dustproof box 40 is The air pressure inside the dustproof box 40 is greater than the external air pressure, which can effectively reduce the risk of dust and other impurities entering the dustproof box 40 with the external air, so as to further improve the dustproof performance of the roller printer. In this way, through the dual protection of the dustproof box 40 and the first boosting mechanism 50, the environment inside the dustproof box 40 can reach the standard of a dust-free workshop above Class 1000, effectively ensuring and improving the dustproof performance of the roller printer. Furthermore, the roller printer can produce high-quality products even in a dust-free workshop below Class 1000, effectively increasing the scope of use and application scenarios of the roller printer, and effectively ensuring and improving the performance of the roller printer.

[0047] See also Figure 9 In this embodiment, the printing mechanism 20 includes a printing roller 21, a creasing roller 22, a first driving structure 23, a second driving structure 24 and a third driving structure 25. The printing roller 21 and the creasing roller 22 are arranged in parallel and spaced apart from each other. The first driving structure 23 is connected to the printing roller 21 and is used to drive the printing roller 21 to rotate around its central axis. The second driving structure 24 is connected to the creasing roller 22 and is used to drive the creasing roller 22 to rotate around its central axis. The third driving structure 25 is connected to the creasing roller 22 and is used to drive the creasing roller 22 to move toward the printing roller 21 to press the material tape against the printing roller 21. The printing roller 21 is used to print the slurry onto the material tape.

[0048] By adopting the above-mentioned scheme, it can be understood that during the normal operation of the roller printing machine, the material belt moves at a preset speed. Furthermore, during the normal operation of the roller printing machine, the third drive structure 25 drives the creasing roller 22 to move toward the printing roller 21 to press the material belt against the printing roller 21. At the same time, the printing roller 21 is driven to rotate around its central axis by the first drive structure 23, and the creasing roller 22 is driven to rotate around its central axis by the second drive structure 24. Furthermore, the slurry can be gradually printed onto the material belt along the length direction of the material belt through the printing roller 21, thereby effectively ensuring the performance of the printing mechanism 20.

[0049] See also Figure 9In this embodiment, the rotation direction of the printing roller 21 is opposite to that of the creasing roller 22. By adopting the above solution, by setting the rotation direction of the printing roller 21 and the rotation direction of the creasing roller 22 in opposite directions, the rotational friction between the printing roller 21 and the material strip, as well as between the creasing roller 22 and the material strip, can be effectively reduced, effectively reducing the resistance to the material strip conveying, facilitating the purpose of achieving the purpose of stable and smooth movement of the material strip, effectively reducing the risk of deflection and deformation of the material strip, and effectively ensuring the printing effect of the printing mechanism 20.

[0050] See also Figure 9 In this embodiment, a connecting portion 251 is convexly provided on the circumferential side of the third driving structure 25, and the printing mechanism 20 further includes a fourth driving structure 26, which includes a connecting shaft 261, an eccentric wheel 262, a transmission member 263 and a driver 264. The connecting shaft 261 is passed through the eccentric hole of the eccentric wheel 262 and rotates synchronously with the eccentric wheel 262. The connecting shaft 261 is parallel to the creasing roller 22 and is spaced apart from the connecting portion 251 along the moving direction of the printing roller 21. The eccentric wheel 262 is arranged opposite to the connecting portion 251. The driver 264 is connected to the connecting shaft 261 and is used to drive the connecting shaft 261 to rotate around the central axis of the connecting shaft 261. One end of the transmission member 263 is sleeved on the eccentric wheel 262, and the other end of the transmission member 263 is connected to the connecting portion 251.

[0051] By adopting the above solution, the third driving structure 25 can be used to drive the creasing roller 22 to move toward the printing roller 21, so as to press the material belt against the printing roller 21, so as to achieve the preliminary adjustment of the distance between the creasing roller 22 and the printing roller 21. Subsequently, the driver 264 drives the connecting shaft 261 to rotate around the central axis of the connecting shaft 261, so as to link the eccentric wheel 262 to rotate around the central axis of the connecting shaft 261 through the connecting shaft 261, thereby changing the distance between the connecting shaft 261 and the connecting portion 251 of the third driving structure 25, and thus adjusting the eccentric wheel 262 to adjust the distance between the connecting shaft 261 and the connecting portion 251 of the third driving structure 25. The heart wheel 262 drives the connecting part 251 to move back and forth along the moving direction of the printing roller 21 through the transmission member 263, thereby realizing further fine-tuning of the distance between the creasing roller 22 and the printing roller 21, that is, realizing precise adjustment of the distance between the creasing roller 22 and the printing roller 21. Furthermore, the fourth driving structure 26 can be used to precisely adjust the distance between the creasing roller 22 and the printing roller 21 according to the printing thickness requirements of different products, thereby effectively ensuring and improving the printing accuracy of the printing mechanism 20, and effectively ensuring and improving the general performance and usage performance of the printing mechanism 20.

[0052] See also Figure 9 、 Figure 10In this embodiment, the printing mechanism 20 also includes a sizing roller 27, a fifth drive structure 28, a sixth drive structure 29 and a feeding structure. The feeding structure is arranged next to the sizing roller 27 and is used to spray slurry toward the sizing roller 27. The sizing roller 27 is arranged next to the printing roller 21 and is arranged parallel to the printing roller 21. The fifth drive structure 28 is used to drive the sizing roller 27 to rotate around the central axis of the sizing roller 27. The sixth drive structure 29 is used to drive the sizing roller 27 to move toward the printing roller 21 and abut against the printing roller 21, so that the slurry on the sizing roller 27 is transferred to the printing roller 21, wherein the rotation direction of the sizing roller 27 is set opposite to the rotation direction of the printing roller 21.

[0053] By adopting the above scheme, the sizing roller 27 is driven by the sixth drive structure 29 to move toward the printing roller 21 and abut against the printing roller 21. Then, the sizing roller 27 is driven to rotate around its central axis by the fifth drive structure 28, and the printing roller 21 is driven to rotate around its central axis by the first drive structure 23, so that the sizing roller 27 and the printing roller 21 are squeezed against each other and rotate relative to each other. Then, the feeding structure can indirectly spray the slurry to the printing roller 21 through the sizing roller 27, which is beneficial to ensure the uniformity of the slurry distribution on the printing roller 21, and further ensure and improve the consistency of the slurry coating thickness printed on the material strip, further ensure and improve the printing quality of the printing mechanism 20, and further ensure and improve the production quality of the roller printing machine.

[0054] See also Figure 10 、 Figure 11 In this embodiment, the printing mechanism 20 also includes a first rotating shaft 230, a second rotating shaft 240, a connecting arm 250, a transmission arm 260 and an adjustment structure 270. The first rotating shaft 230 and the second rotating shaft 240 are both arranged parallel to the sizing roller 27. One end of the connecting arm 250 is connected to the first rotating shaft 230, and the other end of the connecting arm 250 is sleeved on the end of the sizing roller 27 and can rotate relative to the sizing roller 27. The sixth driving structure 29 has a retractable driving shaft 291. One end of the transmission arm 260 is sleeved on the outer side of the first rotating shaft 230 and can rotate relative to the first rotating shaft 230. The other end of the transmission arm 260 is rotatably connected to the driving shaft 291 through the second rotating shaft 240. The first rotating shaft 230 and the driving shaft 291 are both arranged at an angle to the transmission arm 260. The adjustment structure 270 is connected to the transmission arm 260 and is used to drive the transmission arm 260 to rotate relative to the first rotating shaft 230 and the driving shaft 291.

[0055] Based on this, the sixth driving structure 29 drives its driving shaft 291 to extend and retract, so that the transmission arm 260 can rotate relative to the driving shaft 291, that is, the first rotating shaft 230 can be rotated by the transmission arm 260, and then the connecting arm 250 can be driven to swing by the first rotating shaft 230 to achieve the adjustment of the position of the sizing roller 27, and also achieve the preliminary adjustment of the distance between the sizing roller 27 and the printing roller 21. At the same time, by setting up the adjustment structure 270, the transmission arm 260 is driven to rotate slightly relative to the first rotating shaft 230 and the driving shaft 291, and the first rotating shaft 230 is linked to rotate slightly by the transmission arm 260, and then the connecting arm 250 can be driven by the first rotating shaft 230 to swing slightly, so as to achieve a small adjustment of the position of the sizing roller 27, and also achieve precise adjustment of the distance between the sizing roller 27 and the printing roller 21, and then the spacing between the sizing roller 27 and the printing roller 21 can be precisely adjusted according to the printing thickness requirements of different products through the adjustment structure 270, so as to more accurately adjust the amount of slurry transferred to the printing roller 21 through the sizing roller 27, and thus further ensure and improve the printing accuracy of the printing mechanism 20, and further ensure and improve the general performance and usage performance of the printing mechanism 20.

The first detection structure is used to detect the thickness of the material roll of the first material roller 12 located at the unwinding station. The first drive assembly is used to drive the first turntable assembly 11 to rotate based on the detection result of the first detection structure to switch the first material roller 12. The second detection structure 140 is provided on the rotation path of the first material roller 12 and is signal-connected to the first cutting mechanism 150. The second detection structure 140 is used to detect the residual material strip of the first material roller 12 that has been rotated away from the unwinding station. The first cutting mechanism 150 is used to cut off the residual material strip of the first material roller 12 that has been rotated away from the unwinding station based on the detection results of the first detection structure and the second detection structure 140. Among them, the first detection structure and the second detection structure 140 can both be, but are not limited to, alignment sensors. Preferably, the plurality of first material rollers 12 are arranged on the same circumference with the first rotation axis as the center line.

[0059] By adopting the above scheme, by setting up multiple first material rollers 12, after the winding operation of any one of the first material rollers 12 is completed, the first turntable assembly 11 can be driven to rotate by the first driving assembly to switch any other first material roller 12 to the unwinding station and continue the unwinding operation, thereby effectively ensuring the continuity of the unwinding operation. In addition, during the unwinding operation of other first material rollers 12, the first material roller 12 that has been unwound can be replaced, thereby effectively reducing the operation time occupied by replacing the new first material roller 12, and effectively ensuring and improving the continuity and efficiency of the production operation of the entire roller printing machine.

[0060] Based on this, by arranging the first detection structure at the unwinding station, the thickness of the material roll of the first material roller 12 located at the unwinding station can be detected by the first detection structure. If the first detection structure detects that the thickness of the material roll of the first material roller 12 is less than the preset thickness, it means that the first material roller 12 has been unwound. Then, the first drive component can timely drive the first turntable component 11 to rotate according to the detection result of the first detection structure, and switch the first material roller 12 in time; at the same time, by arranging the second detection structure 140 on the rotation path of the first material roller 12, the residual material strip of the first material roller 12 that is turned away from the unwinding station can be detected by the second detection structure 140. If the second detection structure 140 can detect that the residual material strip of the first material roller 12 that is turned away from the unwinding station is If there is residual material strip of the first material roller 12 at the work station, it means that the first material roller 12 has been switched. At this time, the first cutting mechanism 150 can timely and accurately cut off the residual material strip of the first material roller 12 that is turned away from the unwinding station according to the detection results of the first detection structure and the second detection structure 140, which can effectively reduce the risk of misoperation of the first cutting mechanism 150, effectively ensure and improve the cutting reliability and cutting accuracy of the first cutting mechanism 150, and then it can be convenient to stick the residual material strip of the first material roller 12 that is turned away from the unwinding station to the material strip of the first material roller 12 that is turned to the unwinding station, so as to realize the connection and material replacement on different first material rollers 12, so as to ensure the continuity of the unwinding operation of the unwinding mechanism 10.

[0061] Specifically, see Figure 4 , multiple second detection structures 140 can be set up. In this way, multiple second detection structures 140 can be set up in the rotation path of the first material roller 12 to detect the residual material strip of the first material roller 12 that is rotated away from the unwinding station at multiple points, thereby further ensuring and improving the accuracy and reliability of the detection results of the second detection structure 140, and further ensuring and improving the cutting reliability and cutting accuracy of the first cutting mechanism 150.

[0062] See also Figure 13 In this embodiment, the winding mechanism 30 includes a second turntable assembly 31, a second drive assembly 32 connected to the second turntable assembly 31, and at least one winding assembly 33 installed on the second turntable assembly 31. The second drive assembly 32 is used to drive the second turntable assembly 31 to rotate around a second rotation axis so that the winding assembly 33 rotates through the winding station. The second rotation axis is parallel to the central axis of the second turntable assembly 31.

[0063] By adopting the above scheme, the winding assembly 33 is installed on the second turntable assembly 31, so that the second turntable assembly 31 supports the winding assembly 33 to stabilize the installation position and installation state of the winding assembly 33; by setting a second driving assembly 32 connected to the second turntable assembly 31, so that the second turntable assembly 31 is driven to rotate around the second rotation axis through the second driving assembly 32, so that the winding assembly 33 is driven to rotate around the second rotation axis through the second turntable assembly 31 and switch to the winding position, so as to facilitate the winding operation through the winding assembly 33 to ensure the performance of the winding mechanism 30.

[0064] Specifically, see Figure 13 , there are multiple winding assemblies 33, and the multiple winding assemblies 33 are arranged on the same circumference with the second rotation axis as the center line. Preferably, there are two winding assemblies 33, and the two winding assemblies 33 are symmetrically distributed on opposite sides of the second rotation axis. Based on this, after the winding operation of any one of the winding assemblies 33 is completed, the second turntable assembly 31 can be driven to rotate by the second drive assembly 32 to switch any other winding assembly 33 to the winding station and continue the winding operation, effectively ensuring the continuity of the winding operation. In addition, the winding assembly 33 that has been wound can be replaced during the winding operation of other winding assemblies 33, thereby effectively reducing the operation time occupied by replacing the new winding assembly 33, effectively ensuring and improving the continuity and efficiency of the production operation of the entire roller printing machine.

[0065] See also Figure 13 In this embodiment, the second turntable assembly 31 includes a first turntable 311, and the winding assembly 33 includes a first mounting seat 331, a rotating seat 334 and a second material roller 332. The first mounting seat 331 is installed on the first turntable 311, and the rotating seat 334 is rotatably installed on the first mounting seat 331 and can rotate around the third rotation axis relative to the first mounting seat 331. The end of the second material roller 332 is rotatably mounted on the rotating seat 334 and is detachably connected to the rotating seat 334. The third rotation axis is arranged to intersect with the central axis of the second material roller 332.

[0066] By adopting the above-mentioned scheme, the first mounting seat 331 is installed on the first turntable 311, so that the first mounting seat 331 is supported by the first turntable 311 to stabilize the installation position and installation state of the first mounting seat 331, thereby stabilizing the installation position and installation state of the winding assembly 33; and the rotating seat 334 is installed on the first mounting seat 331, so that the rotating seat 334 is supported by the first mounting seat 331 to stabilize the installation position and installation state of the rotating seat 334.

[0067] Based on this, the rotating seat 334 is configured to be rotatable relative to the first mounting seat 331 about the third rotation axis, and the end of the second material roller 332 is rotatably mounted on the rotating seat 334 and detachably connected to the rotating seat 334. In this way, the rotating seat 334 can be first rotated relative to the first mounting seat 331 about the third rotation axis to adjust the side of the rotating seat 334 for mounting the second material roller 332 to a suitable orientation, so that the second material roller 332 can be conveniently and quickly mounted on the rotating seat 334. The rotating seat 334 is then rotated relative to the first mounting seat 331 about the third rotation axis, so that the second material roller 332 can be linked to rotate relative to the first mounting seat 331 about the third rotation axis through the rotating seat 334, and the second material roller 332 is perpendicular to the first turntable 311, so that the second material roller 332 can be switched to the winding position. Then, the winding operation can be performed by rotating the second material roller 332 relative to the rotating seat 334, effectively ensuring the performance of the winding mechanism 30.

[0068] When the second material roller 332 is wound, the second material roller 332 can be rotated relative to the first mounting seat 331 by the rotating seat 334 to rotate the second material roller 332 relative to the first mounting seat 331 in a direction away from the winding station (for example, 90 degrees, 100 degrees, etc.).

[0069] Specifically, see Figure 5 The MLCC high-speed precision fully automatic roller printing machine also includes a second cutting mechanism 160 located adjacent to the rewinding mechanism 30. The second cutting mechanism 160 is used to cut the material to be rewound to control the rewinding amount. The second cutting mechanism 160 can be connected to a signal from a driver that drives the second material roller 332. This allows the second cutting mechanism 160 to determine whether to perform cutting based on whether the number of rotations driven by the driver reaches a preset value, making control of the second cutting mechanism 160 more efficient and simple.

[0070] See also Figure 13In this embodiment, the second turntable assembly 31 also includes a second turntable 312 that is arranged opposite to the first turntable 311 and spaced apart from each other. The second turntable 312 is connected to the first turntable 311 and keeps synchronous rotation; the winding assembly 33 also includes a second mounting seat 333 installed on the second turntable 312, and the second material roller 332 is rotatably mounted on the second mounting seat 333 at one end close to the second turntable 312, and is detachably connected to the second mounting seat 333.

[0071] By adopting the above scheme, a second turntable 312 is set opposite to the first turntable 311 and spaced apart from each other, and the second turntable 312 is connected to the first turntable 311 and keeps rotating synchronously, and the second mounting seat 333 is installed on the second turntable 312, and the second material roller 332 is rotatably installed on the corresponding second mounting seat 333 at one end close to the second turntable 312. Then, the winding assembly 33 can be supported by the first turntable 311 and the second turntable 312, further ensuring the stability and reliability of the installation of the winding assembly 33 and effectively ensuring the performance of the winding mechanism 30.

[0072] The second roller 332 can be fixed on the second mounting base 333 to the workbench 334 so as to prevent the second roller 332 from being damaged. The first and second mounting bases 331 and 333 are connected, and the rotating seat 334 is then rotated around the third rotating axis relative to the first mounting base 331, so as to drive the second material roller 332 to rotate in the direction away from the second mounting base 333 through the rotating seat 334, so that the end of the second material roller 332 away from the rotating seat 334 can be away from other functional components of the winding assembly 33, and then, the second material roller 332 can be conveniently and easily clamped by a forklift at one end away from the mounting base, and the second material roller 332 and the roll material wound on the second material roller 332 can be removed from the mounting base as a whole, which can effectively reduce the risk of other functional components of the winding mechanism 30 being easily touched and damaged by a forklift, thereby effectively protecting and improving the service life of the winding mechanism 30.

[0073] See also Figure 4 、 Figure 5 、 Figure 12In this embodiment, the MLCC high-speed precision fully automatic roller printing machine also includes a scraper mechanism 60 arranged in the dustproof box 40. The scraper mechanism 60 is arranged between the printing mechanism 20 and the winding mechanism 30. The scraper mechanism 60 includes a scraper 61 and a moving component 62. The moving component 62 is connected to the scraper 61 and is used to drive the scraper 61 to abut against the material belt to scrape off excess slurry on the material belt.

[0074] By adopting the above solution, by arranging the scraper mechanism 60 in the dustproof box 40 and arranging the scraper mechanism 60 between the printing mechanism 20 and the winding mechanism 30, the scraper 61 is driven by the moving component 62 to abut against the material belt, thereby scraping off the excess slurry on the material belt, thereby effectively ensuring the uniformity of the slurry thickness on the material belt, and thus effectively ensuring the quality of the products printed by the roller printing machine.

[0075] Specifically, see Figure 12 The moving assembly 62 includes a first moving structure 621, which is connected to the scraper 61 and is used to drive the scraper 61 to move along the first direction a toward the material strip; the moving assembly 62 includes a second moving structure 622, which is rotatably connected to the first moving structure 621 and is used to drive the first moving structure 621 to rotate relative to the second moving structure 622 about an axis parallel to the width direction c of the material strip, so as to adjust the angle between the first driving structure 23 and the material strip, thereby adjusting the angle between the scraper 61 and the material strip; the moving assembly 62 includes a third moving structure 623, which is connected to the second driving structure 24 and is used to drive the second driving structure 24 to move along the second direction b toward the material strip; and the moving assembly 62 includes a fourth moving structure 624, which is connected to the third moving structure 623 and is used to drive the third moving structure 623 to reciprocate along the width direction c of the material strip. The first direction a and the second direction b are set at an angle and are both perpendicular to the width direction c of the material strip. In this way, by setting the first movable structure 621 and the third movable structure 623, the scraper 61 can be moved in a multi-directional direction toward the material belt, so that the scraper 61 can be moved to the material belt quickly and efficiently; by setting the second movable structure 622, the angle between the first drive structure 23 and the material belt can be adjusted, thereby realizing the adjustment of the angle between the scraper 61 and the material belt to meet the production requirements of different products; by setting the fourth movable structure 624, the position of the scraper 61 in the width direction of the material belt can be adjusted through the fourth movable structure 624, so that the position of the scraper 61 in the width direction of the material belt can be intermittently adjusted during operation, thereby realizing the scraping operation of the scraper mechanism 60 on the material belt in all directions, effectively ensuring and improving the all-round and precise adjustment operation of the scraper mechanism 60.

[0076] See also Figure 2 、 Figure 3 、 Figure 6In this embodiment, the MLCC high-speed precision fully automatic roller printing machine also includes a drying mechanism 70, a vent pipe 80 and a second pressurizing mechanism 90. The drying mechanism 70 is arranged between the printing mechanism 20 and the winding mechanism 30, and is used to dry the material strip. The dustproof box 40 includes a drying box body 41 for correspondingly accommodating the drying mechanism 70. The vent pipe 80 and the second pressurizing mechanism 90 are both arranged on the outside of the drying box body 41 and are both connected to the internal space of the drying box body 41. The second pressurizing mechanism 90 is used to increase the air pressure in the drying box body 41 so that the air pressure in the drying box body 41 is greater than the external air pressure.

[0077] By adopting the above scheme, by setting up a drying mechanism 70 between the printing mechanism 20 and the winding mechanism 30, and setting the drying mechanism 70 in the drying box 41, the material strip can be dried quickly and efficiently by the drying mechanism 70, so as to increase the moving speed of the material strip, thereby effectively improving the production efficiency of the roller printing machine; the drying mechanism 70 can also be separated from other components such as the printing mechanism 20 by the drying box 41, which is more conducive to the independent, convenient, efficient and energy-saving control of the temperature in the drying box 41 according to the temperature requirements of the drying mechanism 70 for drying the material strip, thereby effectively ensuring the performance of the drying mechanism 70.

[0078] By arranging the vent pipe 80 and the second pressurizing mechanism 90 on the outside of the drying box 41 and connecting them to the internal space of the drying box 41, part of the gas in the drying box 41 can be discharged in real time through the vent pipe 80, which can effectively reduce the risk of explosion due to the excessive concentration density of explosive chemical components volatilized from the slurry in the gas in the drying box 41, effectively ensuring and improving the safety performance of the roller printing machine. At the same time, the air pressure in the drying box 41 is increased by the second pressurizing mechanism 90 so that the air pressure in the drying box 41 is greater than the external air pressure, which can effectively reduce the risk of dust and other impurities entering the drying box 41 with the external air through the vent pipe 80, effectively ensuring the dustproof performance of the drying box 41 and the dustproof performance of the entire roller printing machine.

[0079] Specifically, see Figure 1 、 Figure 2 The dustproof box 40 includes multiple boxes, and the number of boxes corresponds to the number of mechanisms such as the unwinding mechanism 10, the printing mechanism 20, the drying mechanism 70, the winding mechanism 30, and the control mechanism. The boxes can be assembled together with the corresponding mechanisms to form a device. In this way, it is convenient to assemble, transport, and store the device, and it is convenient to form the roller printing machine of this application by splicing and assembling the various devices. At the same time, the boxes will also be connected and spliced to form the above-mentioned dustproof box 40.

[0080] See also Figure 6 、 Figure 7 、 Figure 8In this embodiment, the drying mechanism 70 includes a first partition plate 71 arranged vertically, and two air chambers 72 arranged on one side of the first partition plate 71. The air chamber 72 extends along the moving direction d of the material belt. The two air chambers 72 are arranged opposite to each other and spaced apart. A drying channel 73 for the material belt to pass through is formed between the two air chambers 72. A wind nozzle 721 is provided on the side of the air chamber 72 facing the drying channel 73. A first air outlet is provided on the side of the air chamber 72 facing the first partition plate 71. The first air outlet and the air nozzle 721 are both connected to the inner side of the ventilation chamber 72. The first partition plate 71 has a second air outlet 711 at one end thereof, corresponding to the first air outlet, and a third air outlet 712 at the other end thereof. Both the second air outlet 711 and the third air outlet 712 are arranged to extend through the thickness of the first partition plate 71. The vent 80 is located on the side of the first partition plate 71 where the air chamber 72 is located. The second pressurizing mechanism 90 is located on the side of the first partition plate 71 away from the air chamber 72. The second pressurizing mechanism 90 is further configured to generate airflow from the third air outlet 712 to the second air outlet 711. The second pressurizing mechanism 90 is preferably, but not limited to, a positive pressure blower 110.

[0081] By adopting the above scheme, a first partition 71 is vertically arranged in the drying box body 41, so that the internal space of the drying box body 41 is divided into two independent spaces by the first partition 71. Furthermore, two air chambers 72 are arranged on one side of the first partition 71, and the ventilation pipe 80 is arranged on the side of the first partition 71 where the air chamber 72 is provided, and a second boosting mechanism 90 is arranged on the other side of the first partition 71, so that the components of the drying mechanism 70 with different functions are arranged in zones, so as to ensure the controllability, stability and reliability of the entire gas circulation of the drying mechanism 70, and effectively ensure the performance of the drying mechanism 70. Based on this, in the process of the material belt passing through the drying channel 73, the second boosting mechanism 90 continuously generates an air flow from the third air port 712 to the second air port 711, so as to promote the gas to be transported from the second air port 711 to the air chamber 72 via the first air port. Then, the gas will be blown toward the material belt through the air nozzle 721 of each air chamber 72 to dry the material belt. Subsequently, the gas portion located on one side of the air chamber 72 returns to the interior of the first partition 71 away from the air chamber 72 via the third air port 712 to recycle the gas for reuse. The gas portion located on one side of the air chamber 72 can also be transported to the outside through the vent pipe 80 to effectively reduce the risk of explosion due to the excessive concentration density of explosive chemical components volatilized from the slurry in the gas in the drying box 41, thereby effectively ensuring and improving the performance and safety of the roller printing machine.

[0082] See also Figure 8In this embodiment, the first air outlet is located at the end of the air chamber 72 away from the printing mechanism 20. By adopting this solution, the flow direction of the air in the air chamber 72 can be set opposite to the moving direction d of the material belt, which is conducive to evaporating the water in the slurry and further ensuring and improving the drying effect of the drying mechanism 70.

[0083] See also Figure 6 、 Figure 7 、 Figure 8 In this embodiment, the drying mechanism 70 further includes a first filter 74 disposed on the side of the partition away from the air chamber 72 . The first filter 74 is disposed opposite to the second air port 711 and is used to filter the gas entering the second air port 711 .

[0084] By adopting the above solution, a first filter 74 is provided on the side of the partition away from the air chamber 72, so that the gas entering the second air port 711 is filtered by the first filter 74. Thus, the risk of dust and other impurities entering the first air port from the second air port 711 and flowing into the air chamber 72 can be effectively reduced, thereby further ensuring and improving the dustproof performance of the roller printing machine.

[0085] See also Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 In this embodiment, the drying mechanism 70 includes a second partition 75 and a third partition 76, both of which are arranged on the side of the first partition 71 away from the air chamber 72. The second partition 75 and the third partition 76 are arranged vertically and spaced apart along the moving direction d of the material belt. The second partition 75 and the third partition 76 divide the internal space of the drying box 41 on the side of the first partition 71 away from the air chamber 72 into a heating area 411, a guide area 412 and a filtering area 413 in sequence. The second partition 75 is provided with a penetrating fifth air outlet 751 in its thickness direction, and the third partition 76 is provided with a penetrating fifth air outlet 751 in its thickness direction. A sixth air outlet is provided in the direction of degree, the second boosting mechanism 90 is provided in the guide area 412, and the first filter 74 is provided in the filtering area 413; the outer side of the drying box body 41 is provided with a fourth air outlet 414 connected to the heating area 411, and the drying mechanism 70 also includes a second filter 77 and a heater 78 both provided in the heating area 411, the second filter 77 is arranged opposite to the fourth air outlet 414, and is used to filter the gas input from the fourth air outlet 414, and the heater 78 is arranged opposite to the sixth air outlet, and is used to heat the gas flowing into the sixth air outlet.

[0086] By adopting the above scheme, a second partition 75 and a third partition 76 are set on the side of the first partition 71 away from the air chamber 72, so that the internal space of the drying box 41 located on the side of the first partition 71 away from the air chamber 72 is divided into a heating area 411, a guide area 412 and a filtering area 413 in sequence by the second partition 75 and the third partition 76. Furthermore, by setting the second boosting mechanism 90 in the guide area 412, setting the first filter 74 in the filtering area 413, and setting the heater 78 in the heating area 411, the purpose of zoning components with different functions is achieved, so as to further ensure and improve the controllability, stability and reliability of the entire gas circulation of the drying mechanism 70, and further ensure the performance of the drying mechanism 70. In addition, the gas passing through it can also be heated by the heater 78 to ensure the temperature of the gas located on the side of the first partition 71 away from the wind chamber 72, and then ensure the temperature of the gas input into the wind chamber 72 and blown toward the material belt, thereby ensuring the drying efficiency and drying effect of the material belt; in addition, by setting a fourth air port 414 connected to the heating area 411 on the outside of the drying box 41, the external gas can be transported to the heating area through the fourth air port 414 to replenish the gas, so as to ensure the flow rate and gas pressure of the gas in the drying box 41. At the same time, a second filter 77 is also provided to filter the gas input from the fourth air port 414, which can effectively reduce the risk of impurities such as dust passing through the fourth air port 414 into the drying box 41 with the gas, further ensuring the dustproof performance of the drying box 41, and further ensuring the dustproof performance of the entire roller printing machine.

[0087] See also Figure 6 、 Figure 7 、 Figure 8 In this embodiment, the drying mechanism 70 also includes a height adjustment structure 79, which is installed on the upper side wall of the drying box 41 and connected to the air chamber 72 located on the upper side. The height adjustment structure 79 is used to drive the air chamber 72 located on the upper side to rise and fall.

[0088] By adopting the above-mentioned scheme, the height adjustment structure 79 is installed on the upper side wall of the drying box body 41, so that the height adjustment structure 79 is supported by the drying box body 41 to stabilize the installation position and installation state of the height adjustment structure 79; by setting the height adjustment structure 79, the height adjustment structure 79 is used to drive the wind chamber 72 located on the upper side to rise and fall, thereby adjusting the height of the drying channel 73, thereby helping to ensure that the material belt can remain in the middle of the two wind chambers 72 during the entire operation, so that the wind conditions of the material belt on both sides of the thickness direction are basically consistent, and thus, it is helpful to make the drying effects of the material belt on both sides of the thickness direction basically consistent, thereby effectively ensuring and improving the drying effect of the drying mechanism 70.

[0089] Specifically, see Figure 1 、 Figure 2 、 Figure 7 , there are multiple drying mechanisms 70 (for example, 2, 3, 6, etc.), and the multiple drying mechanisms 70 are arranged in sequence along the moving direction d of the material belt. Some drying mechanisms 70 close to the printing mechanism 20 are used to pre-dry the material belt, and the other drying mechanisms 70 are used to quickly dry the material belt. Among them, the drying mechanism 70 for pre-drying the material belt and the drying mechanism 70 for quickly drying the material belt are different only in the type of the air nozzle 721. The other structures are the same. For example, the air nozzle 721 of the lower air chamber 72 of the drying mechanism 70 for pre-drying the material belt is the same as the other structures. The roller nozzle 7211 is a nozzle for the roller, while the nozzle 721 of the upper air chamber 72 is an air flotation nozzle 7212 (such as a small hole nozzle). The nozzles 721 of the upper and lower air chambers 72 of the drying mechanism 70 for quickly drying the material strip are all air flotation nozzles 7212. For example, assuming that there are six drying mechanisms 70, the six drying mechanisms 70 are numbered 1, 2, 3, 4, 5, and 6 in the moving direction d of the material strip. Then, drying mechanisms 70 No. 1 to 4 can be set to pre-dry the material strip, and drying mechanisms 70 No. 5 and 6 can be set to quickly dry the material strip. In this way, by pre-drying and quickly drying the material strip in sequence, the drying effect of the drying mechanism 70 can be effectively guaranteed and improved.

[0090] See also Figure 2 、 Figure 3 In this embodiment, the MLCC high-speed precision fully automatic roller printing machine includes a control mechanism, a connecting pipe 100, and a fan 110. The control mechanism is disposed within a dustproof box 40 and is electrically connected to the unwinding mechanism 10, the printing mechanism 20, and the rewinding mechanism 30 via connecting wires. The connecting pipe 100 is disposed outside the dustproof box 40 and communicates with the interior space of the dustproof box 40. The connecting pipe 100 extends from the control mechanism to the unwinding mechanism 10, the printing mechanism 20, and the rewinding mechanism 30, respectively, and is used to accommodate the connecting wires. The fan 110 is connected to the connecting pipe 100 and is used to generate airflow to each end of the connecting pipe 100. The fan 110 is preferably a positive pressure fan 110.

[0091] By adopting the above-mentioned scheme, the control mechanism is set in the dustproof box 40, and the control mechanism is set to be electrically connected to the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 through the connecting wire, so that the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 are controlled by the control mechanism to operate according to a predetermined program, thereby realizing the automated production of the roller printing machine.

[0092] By arranging the connecting pipe 100 outside the dustproof box 40 and connecting it to the internal space of the dustproof box 40, and extending the connecting pipe 100 from the control mechanism to the unwinding mechanism 10, the printing mechanism 20 and the rewinding mechanism 30 respectively, the connecting line can be protected by the connecting pipe 100, which can effectively reduce the risk of accidental touching of the connecting line and causing the connecting line to break. The connecting pipe 100 can also be used to guide and arrange the direction of the connecting line, which can effectively reduce the risk of wire entanglement between different connecting lines, and effectively ensure and improve the performance of the roller printing machine.

[0093] By setting a fan 110 connected to the connecting pipe 100, an airflow flowing toward each end of the connecting pipe 100 is generated by the fan 110. The airflow generated by the fan 110 can make the air pressure in the connecting pipe 100 greater than the external atmospheric pressure, thereby effectively reducing the risk of dust and other impurities entering the dustproof box 40 with the external air through the connecting pipe 100, further ensuring the dustproof performance of the roller printing machine; on the other hand, it can also enable the gas in the connecting pipe 100 to be smoothly transported to the outside, so as to promote the gas with higher temperature around the control mechanism to be smoothly transported to the outside of the dustproof box 40 through the connecting pipe 100, so as to effectively cool the control mechanism, effectively reduce the risk of safety hazards such as open flames in the control mechanism due to excessive temperature in the dustproof box 40, effectively ensure and improve the heat dissipation performance of the dustproof box 40, and effectively ensure and improve the safety of the roller printing machine.

[0094] Among them, see Figure 1 、 Figure 4 、 Figure 5 When the drying mechanism 70 is installed in the MLCC high-speed, precision, fully automatic roller printer, the control mechanism, unwinding mechanism 10, and drying mechanism 70 are all located between the printing mechanism 20 and the rewinding mechanism 30. The unwinding mechanism 10 is located near the printing mechanism 20, the control mechanism is located near the rewinding mechanism 30, and the drying mechanism 70 is located above the unwinding mechanism 10 and the control mechanism. This ensures the performance of the roller printer while making the layout of the various components of the entire roller printer more compact, thereby effectively reducing the size of the entire roller printer and facilitating its miniaturization.

[0095] See also Figure 1 、 Figure 4 、 Figure 5 In this embodiment, the roller printing machine further includes a tension adjustment mechanism 120 , which is disposed in the dustproof box 40 and is used to adjust the tension of the material strip.

[0096] By adopting the above solution, by setting the tension adjustment mechanism 120 in the dustproof box 40, the tension of the material strip can be adjusted in real time through the tension adjustment mechanism 120, so that the tension of the material strip is maintained within the preset tension range, thereby effectively ensuring the stability and reliability of the material strip tension during operation, effectively reducing the risk of deformation of the material strip, and effectively ensuring and improving the production quality of the roller printing machine.

[0097] Specifically, see Figure 4 、 Figure 5 Multiple tension adjustment mechanisms 120 are provided, some of which are located between the unwinding mechanism 10 and the printing mechanism 20, and some of which are located between the printing mechanism 20 and the rewinding mechanism 30. When the drying mechanism 70 is provided, some of the tension adjustment mechanisms 120 are located between the drying mechanism 70 and the rewinding mechanism 30. Based on this, by providing multiple tension adjustment mechanisms 120 and distributing them between different processes, the tension of the web can be adjusted at multiple points through the multiple tension adjustment mechanisms 120, further ensuring and improving the stability and reliability of the web tension during operation, further reducing the risk of web deformation, and further ensuring and improving the production quality of the roller printing machine.

[0098] See also Figure 1 、 Figure 5 In this embodiment, the MLCC high-speed precision fully automatic roller printing machine further includes a detection mechanism 130 disposed within the dustproof box 40. The detection mechanism 130 is disposed between the printing mechanism 20 and the winding mechanism 30 and is used to detect surface defects of the material strip. When the drying mechanism 70 is provided, the detection mechanism 130 is disposed between the drying mechanism 70 and the winding mechanism 30.

[0099] By adopting the above solution, by setting the detection mechanism 130 in the dustproof box 40 and setting the detection mechanism 130 between the printing mechanism 20 and the winding mechanism 30, the surface defects of the material strip can be detected in real time through the detection mechanism 130, thereby effectively reducing the risk of unqualified material strips flowing into the subsequent process, and effectively ensuring and improving the production quality of the roller printing machine.

Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
