Description

Technical Field

[0001] The present invention relates to the technical field of printing machines, in particular to a printing platform and a printing machine. Background Art

[0002] The print platform is the core component of the printer structure that directly carries the print media (such as paper, plastic, metal sheets, etc.) and cooperates with the print head to complete the printing task.

[0003] Chinese patent CN202420235723.9 discloses a belt-guided single-sheet digital printing machine, which belongs to the technical field of inkjet digital printing equipment. The technical solution is: the upper printing platform is composed of a conveyor roller, a main conveyor roller, a printing suction belt and a printing steel plate. An annular printing suction belt is arranged between the conveyor roller and the main conveyor roller. The printing steel plate is placed under the printing suction belt. There are multiple air holes on the printing suction belt. The space between the printing suction belt and the printing steel plate below forms a negative pressure, which absorbs the paper conveyed on the printing suction belt. The lower printing platform and the upper printing platform adopt a belt-guided flat design, which eliminates the influence of the curved printing surface on the printing accuracy; the belt-guided paper turning and conveying mechanism solves the problem of complex and difficult adjustment of the roller turning structure, and eliminates the limitation of the roller diameter on the size of the turned paper; it is convenient for later replacement and maintenance, and at the same time reduces the footprint of the machine.

[0004] The aforementioned device must sequentially pass through a complex series of devices, including a paper feed mechanism, an upper deflection correction mechanism, a multi-sheet rejection mechanism, a paper detection mechanism, an upper printing platform, a paper reversing and conveying mechanism, a lower deflection correction mechanism, a lower printing platform, and a paper collection mechanism. This multi-step, lengthy process requires a large number of duplicate mechanical structures and control units, significantly increasing equipment costs. Furthermore, during the paper reversal process, the paper must leave the original conveying path and re-enter the lower printing platform for positioning. This repositioning step is not only time-consuming but also subject to certain fluctuations in positioning accuracy, significantly impacting overall printing efficiency. Summary of the Invention

[0005] In response to the above problems, a printing platform and a printing machine are provided. The printing platform can effectively reduce printing costs while ensuring printing efficiency.

[0006] In order to solve the problems of the existing technology, the present invention provides a printing platform, including a horizontal movable slide, which is provided with a folding and transposition area and a printing area, and a folding mounting seat is installed on the movable end of the horizontal movable slide.

[0007] Preferably, a plurality of first limit mounting grooves are provided on the fixed mounting seat, and a plurality of first clamping mounting mechanisms for clamping and fixing the adsorption placement plate are also installed on the fixed mounting seat. The first clamping mounting mechanism includes an interpenetrating clamping plate slidably installed on the fixed mounting seat, and the clamping end of the interpenetrating clamping plate extends toward the first limit mounting groove, and a first spring is installed between the clamping end of the interpenetrating clamping plate and the fixed mounting seat.

[0008] Preferably, a plurality of guide columns are provided on the flip mounting seat, and a plurality of lifting mounting plates are installed on the guide columns. A downward pressure adjustment device is installed between each lifting mounting plate and the flip mounting seat. The downward pressure adjustment device is used to drive the lifting mounting plate to move up and down. A second clamping mounting mechanism is installed on each lifting mounting plate, and a plurality of second limit mounting grooves are provided on the lifting mounting plate.

[0009] Preferably, the downward pressure adjustment device includes a pushing airbag installed between the lifting mounting plate and the flip mounting seat, and the pushing airbag is connected to the inflation device through an air supply pipe.

[0010] Preferably, the flipping buffer mechanism includes a resistance mounting block on the flipping mounting seat, a limiting sliding sleeve installed on the fixed mounting seat, a telescopic resistance rod installed in the limiting sliding sleeve, and an angled guide frame installed below the telescopic resistance rod, and the angled guide frame is fixedly connected to the horizontal movable slide.

[0011] Preferably, the fixed adsorption placement plate and the movable adsorption placement plate have the same structure, and a horizontal bearing surface is provided on the top of the fixed adsorption placement plate, which is covered with adsorption holes for fixing the paper.

[0012] Preferably, the guiding and correcting device includes a correcting guiding mechanism on the side of the horizontal movable slide, and a visual detector and a correcting pushing device are installed at the guiding end of the correcting guiding mechanism. The visual detector is used to detect the position of the printing paper, and the correcting pushing device is used to adjust the position of the printing paper.

[0013] Preferably, the guiding and correcting device includes a correcting guiding mechanism on the side of the horizontal movable slide, and a visual detector and a correcting pushing device are installed at the guiding end of the correcting guiding mechanism. The visual detector is used to detect the position of the printing paper, and the correcting pushing device is used to adjust the position of the printing paper.

[0014] Preferably, the correction pushing device includes a fixed mounting plate installed on the guide right-angle rail, a limiting slide groove is provided on the fixed mounting plate, a movable slider is installed inside the limiting slide groove, a second linear drive is also installed on the side of the fixed mounting plate, the output end of the second linear drive is connected to the movable slider, a third linear drive is installed on the movable slider, and a horizontal bonding plate is installed at the output end of the third linear drive, and the horizontal bonding plate is provided with multiple limiting suction cups.

[0015] The present invention also provides a printing machine, wherein a printing platform is adopted.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Traditional multi-step, lengthy printing processes require numerous repetitive mechanical structures and control units, significantly increasing equipment costs. This printing platform, however, utilizes an innovative design that integrates loading, printing, flipping, and unloading functions into a compact structure. A horizontally movable slide allows paper to flow between different functional areas, eliminating the need for independent and complex transfer mechanisms. This integrated design significantly reduces the number of mechanical components and control units, significantly lowering equipment manufacturing costs while improving integration and reliability, making it easier to maintain and manage.

[0018] 2. In traditional equipment, the paper flipping process requires separation from the original conveying path and repositioning, which can easily cause fluctuations in positioning accuracy. This printing platform is equipped with two sets of guiding and correcting devices. During the paper loading stage, the guiding and correcting devices work together with the loading device to accurately convey the paper to the fixed adsorption placement plate and precisely adjust it to ensure that the paper is accurately placed in the specified position. During the paper flipping process, the flipping buffer mechanism ensures the stability of the flipping mounting process. The movable adsorption placement plate and the fixed adsorption placement plate tightly adhere to the paper, preventing the paper from shifting during the flipping process. This maintains high-precision positioning of the paper throughout the printing process, effectively improving print quality.

[0019] 3. The paper flipping and repositioning steps of traditional equipment are time-consuming, affecting the overall printing efficiency. When the fixed adsorption placement plate is used for single-sided printing on this printing platform, the flip mounting base can simultaneously perform paper flipping and positioning operations, preparing for subsequent double-sided printing, and realizing the parallel operation of single-sided printing and paper flipping and positioning. At the same time, when the paper on the movable adsorption placement plate is printed on both sides, the fixed adsorption placement plate can simultaneously load the new paper and print on one side, and the unloading device promptly removes the paper that has completed double-sided printing. The close connection between each process greatly shortens the paper processing time and significantly improves the printing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See also Figures 1 to 11 As shown, a printing platform includes a horizontal movable slide 1, which is provided with a folding and transposition area and a printing area. A folding mounting seat 2 is installed on the movable end of the horizontal movable slide 1, and the folding mounting seat 2 is composed of a fixed mounting seat 21 and a flip mounting seat 22. A flip buffer mechanism 23 is installed between the fixed mounting seat 21 and the flip mounting seat 22. A fixed adsorption placement plate 3 is installed on the fixed mounting seat 21, and a movable adsorption placement plate 4 is installed on the flip mounting seat 22. The movable adsorption placement plate 4 and the fixed adsorption placement plate 3 are both used for limiting the adsorption of printing paper. Two sets of guiding and correcting devices 5 are provided on both sides of the horizontal movable slide 1, and the guiding and correcting devices 5 are used to correct the position of the printing paper.

[0035] A printing device 9 is provided above the printing area, a feeding device 8 is provided beside the printing area, and a feeding device 7 is provided beside the folding and transposition area.

[0036] When double-sided printing is required, the horizontally movable slide 1 drives the folding mount 2 to the folding and transposition area. At this point, the guiding and correcting device 5 activates, and its working end moves above the fixed suction placement plate 3. Subsequently, the guiding and correcting device 5 and the loading device 7 activate in conjunction, feeding the paper 6 onto the fixed suction placement plate 3. The guiding and correcting device 5 precisely adjusts the paper 6 to ensure that it is accurately placed in the designated position. After the paper 6 is placed, the fixed suction placement plate 3 absorbs the paper 6 and positions it.

[0037] After the paper 6 is positioned, the horizontal sliding platform 1 drives the fixed adsorption placement plate 3 above the fixed mounting seat 21 to move to the printing area. The printing device 9 performs single-sided printing on the placed paper 6.

[0038] After one side of the paper 6 is printed, the horizontally movable slide 1 drives the folding mounting seat 2 back to the folding transposition area. Then, the flip mounting seat 22 performs a flipping movement, driving the movable adsorption placement plate 4 to flip synchronously. The flipping buffer mechanism 23 plays a role in ensuring the stability of the flipping process of the flip mounting seat 22. After flipping, the movable adsorption placement plate 4 moves to just above the fixed adsorption placement plate 3. Subsequently, the flip mounting seat 22 drives the movable adsorption placement plate 4 to descend, so that the adsorption surface of the movable adsorption placement plate 4 fits with the top of the printed paper on the fixed adsorption placement plate 3, and adsorbs and positions the paper 6. After adsorbing the paper 6, the flip mounting seat 22 is reset, and after resetting, it just stays in the printing area.

[0039] After the flip mount 22 is reset and stays in the printing area, the printing device 9 prints the other side of the flipped printing paper. At this time, the fixed adsorption placement plate 3 stays in the folding and transposition area, and the guiding correction device 5 cooperates with the loading device 7 to place the new printing paper on the fixed adsorption placement plate 3. When the double-sided printing of the printing paper on the movable adsorption placement plate 4 is completed, the horizontal movable slide 1 drives the fixed adsorption placement plate 3 to move to the printing area again, and the printing device 9 prints on one side of the newly placed printing paper. At the same time, the unloading device 8 unloads and removes the printing paper that has completed double-sided printing on the movable adsorption placement plate 4. This printing platform can effectively reduce the size of the equipment and reduce production costs, while ensuring the positioning accuracy of the paper 6 and the efficiency of the printing operation.

[0040] See also Figures 1 to 8 As shown, a plurality of first limiting mounting grooves 211 are provided on the fixed mounting seat 21, and a plurality of first clamping mounting mechanisms 212 for clamping and fixing the adsorption placement plate 3 are also installed on the fixed mounting seat 21. The first clamping mounting mechanism 212 includes an interlaced clamping plate 2121 slidably installed on the fixed mounting seat 21, and the clamping end of the interlaced clamping plate 2121 extends toward the first limiting mounting groove 211, and a first spring 2122 is installed between the clamping end of the interlaced clamping plate 2121 and the fixed mounting seat 21.

[0041] When it is necessary to install the fixed adsorption placement plate 3, the staff adjusts the position of the insertion card plate 2121. During this process, the insertion card plate 2121 is subjected to an external force, causing the first spring 2122 to be squeezed, thereby causing the insertion card plate 2121 to slide away from the first limiting installation slot 211. At this time, the first limiting installation slot 211 is in an open state. The staff inserts the clamping end of the fixed adsorption placement plate 3 into the first limiting installation slot 211. Subsequently, due to the elastic restoring force of the first spring 2122, after the external force on the insertion card plate 2121 is released, the first spring 2122 pushes the insertion card plate 2121 to move toward the first limiting installation slot 211. The clamping end of the insertion card plate 2121 is inserted into the clamping part of the fixed adsorption placement plate 3, thereby inserting and fixing the fixed adsorption placement plate 3 on the fixed mounting seat 21.

[0042] Through the above-mentioned assembly method composed of the first limiting mounting groove 211 and the first clamping mounting mechanism 212, when installing the fixed adsorption placement plate 3, the elastic deformation and recovery characteristics of the first spring 2122 are utilized to realize the clamping and release of the fixed adsorption placement plate 3 by the interlaced clamping plate 2121, which can effectively improve the convenience of installation of the fixed adsorption placement plate 3, facilitate the installation operation of the staff, and at the same time ensure the stability of the fixed adsorption placement plate 3 after installation, meeting the working requirements of the printing platform.

[0043] See also Figures 1 to 7 As shown, a plurality of guide columns 222 are provided on the flip mounting seat 22, and a plurality of lifting mounting plates 223 are installed on the guide columns 222. A downward pressure adjustment device is installed between each lifting mounting plate 223 and the flip mounting seat 22. The downward pressure adjustment device is used to drive the lifting mounting plate 223 to move up and down. A second clamping mounting mechanism 224 is installed on each lifting mounting plate 223, and a plurality of second limit mounting grooves 2231 are provided on the lifting mounting plate 223.

[0044] The downward pressure adjustment device is used to drive the elevating mounting plate 223 to move up and down along the guide pillars 222. Each elevating mounting plate 223 is provided with a plurality of second limiting mounting slots 2231 and is equipped with a second snap-fit ​​mounting mechanism 224. The second snap-fit ​​mounting mechanism 224 has the same structure as the first snap-fit ​​mounting mechanism 212 and is used to snap-fit ​​the movable adsorption placement plate 4. Furthermore, the flip mounting base 22 is driven to flip by a rotation drive device 221. This rotation drive device 221 is conventional and will not be described in detail here.

[0045] When the movable adsorption placement plate 4 needs to flip the paper 6 on the fixed adsorption placement plate 3, the rotary drive device 221 is activated, driving the flip mounting base 22 to flip. During the flipping process, the flipping buffer mechanism 23 works to effectively ensure the stability of the flipping and accurately move the movable adsorption placement plate 4 above the fixed adsorption placement plate 3.

[0046] After flipping into position, the downward pressure adjustment mechanism begins to operate, controlling the lifting mounting plate 223 to adjust downward along the guide post 222. Since the movable suction placement plate 4 is mounted on the lifting mounting plate 223 via the second clamping mounting mechanism 224, the lifting mounting plate 223 drives the movable suction placement plate 4 downward in a synchronous manner until the movable suction placement plate 4 contacts the paper 6 on the fixed suction placement plate 3. At this point, the movable suction placement plate 4 activates its suction function, securing the paper 6, while the fixed suction placement plate 3 releases its suction on the paper 6.

[0047] After the paper 6 is secured by the movable adsorption plate 4, the downward pressure adjustment device is reset, driving the movable adsorption plate 4 with the paper 6 adsorbed thereon to rise, allowing the paper 6 to separate from the fixed adsorption plate 3. The rotary drive device 221 then operates again, driving the flip mount 22 to flip and reset, thereby achieving flip adjustment of the paper 6 and preparing for the subsequent double-sided printing operation.

[0048] See also Figures 5 to 7 As shown, the downward pressure adjustment device includes a pushing airbag 225 installed between the lifting mounting plate 223 and the flip mounting seat 22, and the pushing airbag 225 is connected to the inflation device through an air pipeline 226.

[0049] The connection of the inflation device can control the air pressure inside the push airbag 225. The inflation device is a prior art and will not be described in detail here.

[0050] When the movable adsorption placement plate 4 is accurately moved to above the fixed adsorption placement plate 3, and the movable adsorption placement plate 4 needs to be adjusted downward, the inflator releases the gas in the pushing airbag 225. At this time, the pushing airbag 225 loses its pushing force, and the lifting mounting plate 223 is adjusted downward along the guide pillars 222. The lifting mounting plate 223 drives the movable adsorption placement plate 4 to move downward synchronously. When the movable adsorption placement plate 4 needs to be pushed upward, the inflator supplies air pressure to the pushing airbag 225, and the pushing airbag 225 pushes the lifting mounting plate 223 upward along the guide pillars 222. Pneumatic control can effectively achieve buffered downward pressure.

[0051] See also Figures 1 to 4 As shown, the flip buffer mechanism 23 includes a resistance mounting block 234 on the flip mounting seat 22, a limiting sleeve 232 mounted on the fixed mounting seat 21, a telescopic resistance rod 233 installed in the limiting sleeve 232, and an angled guide frame 231 installed below the telescopic resistance rod 233, and the angled guide frame 231 is fixedly connected to the horizontal movable slide 1.

[0052] During operation of the printing platform, when the fixed mount 21 moves with the horizontally movable slide 1 to the folding and transposition zone, the bevel guide 231 comes into play. Since the bevel guide 231 is fixedly connected to the horizontally movable slide 1, the telescopic interference rod 233 is located within the limiting sleeve 232 and contacts the bevel guide 231 from below. As the fixed mount 21 moves, the bevel guide 231 guides the telescopic interference rod 233 upward along the limiting sleeve 232.

[0053] When the paper 6 needs to be flipped and the flip mount 22 starts to perform the flipping movement, the interference mounting block 234 installed on the flip mount 22 will rotate together with the flip mount 22. During the rotation process, the interference mounting block 234 will gradually conflict with the telescopic interference rod 233 after rising. Since the telescopic interference rod 233 has a certain degree of elasticity, the interference between the interference mounting block 234 and the telescopic interference rod 233 can effectively buffer the flipping movement of the flip mount 22, thereby ensuring the stability of the flipping process. This stability guarantee helps the movable adsorption placement plate 4 to accurately move to just above the fixed adsorption placement plate 3, and in subsequent operations such as descending, adsorbing paper 6 and resetting, it ensures the working accuracy and reliability of the entire printing platform, reduces the positioning deviation of the paper 6 or other printing problems that may be caused by unstable flipping, and thus improves the efficiency and quality of the printing operation. It also helps to reduce the risk of wear and failure during the operation of the equipment and extend the service life of the equipment.

[0054] See also Figures 2 to 7 As shown, the fixed adsorption placement plate 3 and the movable adsorption placement plate 4 have the same structure. A horizontal bearing surface 31 is provided on the top of the fixed adsorption placement plate 3 , and the horizontal bearing surface 31 is covered with adsorption holes 32 for fixing the paper 6 .

[0055] The bottom of the fixed adsorption placement plate 3 is provided with a plurality of insertion protrusions 33, each of which is provided with an insertion hole 34. When the fixed adsorption placement plate 3 is installed, these insertion protrusions 33 cooperate with the first limiting installation slot 211 on the fixed mounting seat 21. A staff member operates the first clamping installation mechanism 212 on the fixed mounting seat 21, causing the insertion clamping plate 2121 to move, compressing the first spring 2122 and opening the first limiting installation slot 211. At this point, the insertion protrusions 33 on the bottom of the fixed adsorption placement plate 3 are inserted into the first limiting installation slot 211. The external force on the insertion clamping plate 2121 is then released. The elastic restoring force of the first spring 2122 pushes the insertion clamping plate 2121 toward the first limiting installation slot 211, and the clamping end of the insertion clamping plate 2121 is inserted into the insertion hole 34 on the insertion protrusions 33 of the fixed adsorption placement plate 3, thereby achieving a secure clamping position of the fixed adsorption placement plate 3 on the fixed mounting seat 21.

[0056] A horizontal supporting surface 31 is provided on the top of the fixed adsorption placement plate 3, which provides a support plane for the horizontal placement of the printing paper. The horizontal supporting surface 31 is evenly covered with adsorption holes 32, and these adsorption holes 32 are connected to an external adsorption device through a pipe or other connection method. When the printing paper needs to be placed, under the coordinated action of the guiding and correcting device 5 and the feeding device 7, the paper 6 is transported to the horizontal supporting surface 31 of the fixed adsorption placement plate 3. At this time, the adsorption device is started, and a suction effect is generated through the adsorption holes 32. The atmospheric pressure difference is used to make the printing paper fit tightly on the horizontal supporting surface 31, thereby achieving effective adsorption and fixation of the printing paper, ensuring that the paper 6 will not be displaced during the subsequent printing process, and providing a stable basis for placing the paper 6 for the printing operation.

[0057] See also Figures 1 to 9 As shown, the guiding and correcting device 5 includes a correcting guiding mechanism 51 on the side of the horizontal movable slide 1, and a visual detector 52 and a correcting pushing device 53 are installed at the guiding end of the correcting guiding mechanism 51. The visual detector 52 is used to detect the position of the printing paper, and the correcting pushing device 53 is used to adjust the position of the printing paper.

[0058] When the printing platform needs to perform duplex printing and the loading device 7 begins to feed paper 6 to the fixed adsorption placement plate 3, the correction guide mechanism 51 of the guide and correction device 5 located on both sides of the horizontal movable slide 1 will first be activated. The guide end of the correction guide mechanism 51 is pre-positioned to a designated position on the fixed adsorption placement plate 3. This designated position is set based on the correct placement of the printing paper on the fixed adsorption placement plate 3. During the feeding process of paper 6, the correction guide mechanism 51 guides the paper 6, allowing it to move along a predetermined path toward the fixed adsorption placement plate 3, effectively guiding the paper 6 to the designated position.

[0059] After the loading device 7 initially places the paper 6 on the fixed suction placement plate 3, the paper 6 is located between the two correction guide mechanisms 51. A visual detector 52, mounted at the leading end of the correction guide mechanism 51, begins operating to inspect the paper 6 remaining in this position. The visual detector 52 compares the image of the paper 6 with a pre-set standard image or position information to determine whether the paper 6 is accurately located at the designated position on the fixed suction placement plate 3.

[0060] If the visual detector 52 detects that the paper 6 is not properly positioned, that is, deviates from the pre-set standard position, the corrective pusher 53 will immediately activate. The corrective pusher 53 pushes and adjusts the paper 6. Based on the position deviation information provided by the visual detector 52, the pusher precisely controls the direction and force of the push, gradually moving the paper 6 to the designated position on the fixed suction placement plate 3. Once the paper 6 is correctly positioned, the fixed suction placement plate 3 immediately activates its suction function, firmly securing the paper 6 in place, thus completing the automatic correction process for the paper 6.

[0061] See also Figures 9 to 11 As shown, the correction guide mechanism 51 includes a fixed mounting frame 511 installed on the side of the horizontal moving slide 1, a first linear drive 512 is installed on the fixed mounting frame 511, a telescopic mounting frame 513 is installed on the output end of the first linear drive 512, a guide right-angle rail 514 is slidably installed on the telescopic mounting frame 513, and a second spring 515 is installed between the guide right-angle rail 514 and the telescopic mounting frame 513.

[0062] The guide right-angle rail 514 is provided with a guide edge and a position-limiting blocking edge, and one end of the position-limiting blocking edge is provided with a guide bevel.

[0063] The fixed mounting frame 511 in the correction guide mechanism 51 is securely mounted on the side of the horizontally movable slide 1, providing support for the entire mechanism. A first linear actuator 512 is mounted on the fixed mounting frame 511, and the output end of the first linear actuator 512 is connected to the telescopic mounting frame 513. When not in operation, the telescopic mounting frame 513 is in its initial position, with the guide right-angle rail 514 slidingly mounted on the telescopic mounting frame 513. A second spring 515 is installed between the guide right-angle rail 514 and the telescopic mounting frame 513, and is in its natural position.

[0064] When the printing platform needs to perform duplex printing and the loading device 7 begins feeding paper 6 onto the fixed adsorption placement plate 3, the first linear actuator 512 is activated. This drives the telescopic mounting frame 513 toward the fixed adsorption placement plate 3. Because the telescopic mounting frame 513 is connected to the guide rail 514, its movement causes the guide rail 514 to move synchronously. During the movement of the guide rail 514, the beveled guide edge at one end of its stopper edge first contacts the side of the fixed adsorption placement plate 3. As the rail 514 continues to move, it is squeezed by the side of the fixed adsorption placement plate 3, causing it to move upward and compress the second spring 515. The second spring 515 undergoes elastic deformation when squeezed, storing elastic potential energy. Under the elastic force of the second spring 515, the bottom of the guide rail 514 is tightly aligned with the top of the fixed adsorption placement plate 3, ensuring the stability and accuracy of the guide rail 514 during subsequent paper 6 guidance.

[0065] The guide right-angle rail 514 is provided with a guide edge and a position-limiting blocking edge, wherein the guide edge is used to guide the limited movement of the paper 6. When the paper 6 approaches the guide right-angle rail 514 during the conveying process, the guide edge will contact the paper 6, exerting a lateral guiding force on the paper 6, so that the paper 6 can move along the path set by the guide edge, thereby guiding the movement direction of the paper 6. The position-limiting blocking edge is used to limit and block the moving position of the paper 6. When the paper 6 moves to a certain position, the position-limiting blocking edge will prevent the paper 6 from continuing to move, ensuring that the paper 6 can accurately stay in the designated area of ​​the fixed adsorption placement plate 3. Through the coordinated action of the guide edge and the position-limiting blocking edge, the correction guide mechanism 51 can effectively guide the paper 6 to the designated position, laying the foundation for the subsequent detection of the position of the paper 6 by the visual detector 52 and possible position adjustment, ensuring the accuracy and reliability of the printing platform during the paper 6 positioning process.

[0066] See also Figures 9 to 11 As shown, the correction pushing device 53 includes a fixed mounting plate 531 installed on the guide right-angle rail 514, a limiting slide groove 5311 is provided on the fixed mounting plate 531, a movable slider 533 is installed inside the limiting slide groove 5311, and a second linear drive 532 is also installed on the side of the fixed mounting plate 531, the output end of the second linear drive 532 is connected to the movable slider 533, and a third linear drive 534 is installed on the movable slider 533, and a horizontal bonding plate 535 is installed on the output end of the third linear drive 534, and the horizontal bonding plate 535 is provided with multiple limiting suction cups.

[0067] The fixed mounting plate 531 is provided with a limiting groove 5311, inside which is mounted a movable slider 533, which can slide within the limiting groove 5311. A second linear actuator 532 is mounted on the side of the fixed mounting plate 531. The output end of the second linear actuator 532 is connected to the movable slider 533, and is used to drive the movable slider 533 to move within the limiting groove 5311. A third linear actuator 534 is mounted on the movable slider 533. The output end of the third linear actuator 534 is connected to the horizontal laminating plate 535, on which a plurality of limiting suction cups are provided. When not in operation, the third linear actuator 534 is in a retracted state, the horizontal laminating plate 535 is in a higher position, the limiting suction cups are not in contact with the paper 6, the second linear actuator 532 is also in its initial position, and the movable slider 533 does not move.

[0068] When the visual detector 52 detects that the paper 6 is not properly placed and deviates from the preset standard position, the corrective pushing device 53 is activated. First, the third linear actuator 534 begins to operate, driving the horizontal laminating plate 535 downward. As the horizontal laminating plate 535 descends, the multiple limiting suction cups gradually approach the surface of the paper 6 until they are firmly attached to the paper 6. At this point, the limiting suction cups generate suction force, firmly adhering the paper 6 to the horizontal laminating plate 535.

[0069] After the limiting suction cup absorbs the paper 6, the second linear drive 532 is started. The second linear drive 532 pushes the movable slider 533 to move in the limiting slide groove 5311. Since the movable slider 533 is connected to the third linear drive 534, the horizontal laminating plate 535 and the absorbed paper 6, the movement of the movable slider 533 will drive the third linear drive 534, the horizontal laminating plate 535 and the paper 6 to move synchronously. During the movement, the second linear drive 532 will accurately control the direction and force of movement according to the position deviation information of the paper 6 fed back by the visual detector 52. It realizes the precise displacement adjustment of the paper 6 on the fixed adsorption placement plate 3, so that the paper 6 gradually moves to the pre-set standard position. When the paper 6 is adjusted to the correct position, the fixed adsorption placement plate 3 starts the adsorption function to firmly fix the paper 6 in that position.

[0070] The present invention also provides a printing machine, wherein a printing platform is adopted.

[0071] Specific working principle:

[0072] When double-sided printing is required, the horizontal movable slide 1 drives the folding mount 2 to the folding and transposition area. At this point, the guiding and correcting device 5 activates, and its working end moves above the fixed suction placement plate 3. Subsequently, the guiding and correcting device 5 and the loading device 7 activate in conjunction, feeding the paper 6 onto the fixed suction placement plate 3. The guiding and correcting device 5 precisely adjusts the paper 6 to ensure it is accurately placed in the designated position. After the paper 6 is placed, the fixed suction placement plate 3 absorbs and positions the paper 6. After positioning the paper 6, the horizontal movable slide 1 drives the fixed suction placement plate 3 above the fixed mount 21 to the printing area. The printing device 9 performs single-sided printing on the placed paper 6. After printing on one side of the paper 6, the horizontal movable slide 1 drives the folding mount 2 back to the folding and transposition area. Next, the flipping mount 22 flips, causing the movable suction placement plate 4 to flip synchronously. The flipping buffer mechanism 23 ensures the stability of the flipping mount 22 during the flipping process. After flipping, the movable suction placement plate 4 moves directly above the fixed suction placement plate 3. Subsequently, the flip mount 22 drives the movable adsorption placement plate 4 downward, so that the adsorption surface of the movable adsorption placement plate 4 is in contact with the top of the printed paper on the fixed adsorption placement plate 3, and the paper 6 is adsorbed and positioned. After adsorbing the paper 6, the flip mount 22 is reset and stays in the printing area after reset.

[0073] After the flip mount 22 is reset and stays in the printing area, the printing device 9 prints the other side of the flipped printing paper. At this time, the fixed adsorption placement plate 3 stays in the folding and transposition area, and the guiding correction device 5 cooperates with the loading device 7 to place the new printing paper on the fixed adsorption placement plate 3. When the double-sided printing of the printing paper on the movable adsorption placement plate 4 is completed, the horizontal movable slide 1 drives the fixed adsorption placement plate 3 to move to the printing area again, and the printing device 9 prints on one side of the newly placed printing paper. At the same time, the unloading device 8 unloads and removes the printing paper that has completed double-sided printing on the movable adsorption placement plate 4. This printing platform can effectively reduce the size of the equipment and reduce production costs, while ensuring the positioning accuracy of the paper 6 and the efficiency of the printing operation.
