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. The folding mounting seat is composed of a fixed mounting seat and a flip mounting seat, and a flip buffer mechanism is installed between the fixed mounting seat and the flip mounting seat. A fixed adsorption placement plate is installed on the fixed mounting seat, and a movable adsorption placement plate is installed on the flip mounting seat. Both the movable adsorption placement plate and the fixed adsorption placement plate are used for limiting the adsorption of printing paper. Two sets of guiding and correcting devices are provided on both sides of the horizontal movable slide, and the guiding and correcting devices are used to correct the position of the printing paper.

[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 plates 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 clamp 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 and guiding mechanism on the side of the horizontal moving slide. A vision detector and a correcting and pushing device are installed at the guiding end of the correcting and guiding mechanism. The vision detector is used to detect the position of the printing paper, and the correcting and pushing device is used to adjust the position of the printing paper.

[0014] Preferably, the correcting and pushing device includes a fixed mounting plate installed on the guiding right-angle rail. A limiting sliding groove is provided on the fixed mounting plate. A moving slider is installed inside the limiting sliding groove. A second linear driver is also installed on the side of the fixed mounting plate. The output end of the second linear driver is connected to the moving slider. A third linear driver is installed on the moving slider. The output end of the third linear driver is installed with a horizontal fitting plate, and the horizontal fitting plate is provided with a plurality of limiting suction cups.

[0015] The present invention also provides a printing machine, which adopts a printing platform.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. Traditional printing equipment with multiple links and long processes requires a large number of repetitive mechanical structures and control units, resulting in a significant increase in equipment costs. However, this printing platform adopts an innovative design, integrating functions such as feeding, printing, flipping, and discharging into a compact structure. The paper is transferred between different functional areas through a horizontal moving slide, eliminating the need for independent and complex transfer conveyors. This integrated design significantly reduces the number of mechanical components and control units, significantly reducing the equipment manufacturing cost. At the same time, it improves the integration and reliability of the equipment, facilitating equipment maintenance and management.

[0017] 2. In traditional equipment, during the paper flipping process, the paper needs to be separated from the original conveying path and repositioned, which is prone to fluctuations in positioning accuracy. This printing platform is equipped with two sets of guiding and correcting devices. During the paper feeding stage, the guiding and correcting device works in coordination with the feeding 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 stability of the flipping mounting seat during flipping is ensured through the flipping buffer mechanism. The movable adsorption placement plate and the fixed adsorption placement plate are closely attached to adsorb the paper, preventing the paper from shifting during the flipping process, thus maintaining high-precision positioning of the paper throughout the printing process and effectively improving the printing quality.

[0018] 3. The time-consuming paper flipping and repositioning steps of traditional equipment affect the overall printing efficiency. When the fixed adsorption placement plate of this printing platform is used for single-sided printing, the flipping mounting seat can simultaneously perform paper flipping and positioning operations, preparing for subsequent double-sided printing, and realizing parallel operations of single-sided printing and paper flipping and positioning. At the same time, when double-sided printing is carried out on the paper on the movable adsorption placement plate, the fixed adsorption placement plate can simultaneously perform loading and single-sided printing of new paper, and the unloading device timely removes the paper that has completed double-sided printing. The connection between each process is tight, greatly shortening the paper processing time and significantly improving the printing operation efficiency. Brief Description of the Drawings

Detailed implementation manners

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] See Figures 1 to 11 As shown, a printing platform includes a horizontal moving slide 1. There are a folding conversion area and a printing area on the horizontal moving slide 1. A folding mounting base 2 is installed on the movable end of the horizontal moving slide 1. The folding mounting base 2 is composed of a fixed mounting base 21 and a flipping mounting base 22. A flipping buffer mechanism 23 is installed between the fixed mounting base 21 and the flipping mounting base 22. A fixed adsorption placement plate 3 is installed on the fixed mounting base 21, and a movable adsorption placement plate 4 is installed on the flipping mounting base 22. Both the movable adsorption placement plate 4 and the fixed adsorption placement plate 3 are used for limiting and adsorbing printing paper. Two groups of guiding and correcting devices 5 are arranged on both sides of the horizontal moving slide 1, and the guiding and correcting device 5 is used for correcting the position of the printing paper.

[0033] A printing device 9 is arranged above the printing area, a blanking device 8 is configured beside the printing area, and a loading device 7 is arranged beside the folding conversion area.

[0034] When double-sided printing is required, the horizontal moving slide 1 drives the folding mounting base 2 to move to the folding conversion area. At this time, the guiding and correcting device 5 is activated, and the working end of the guiding and correcting device 5 moves above the fixed adsorption placement plate 3. Subsequently, the guiding and correcting device 5 and the feeding device 7 are started in coordination to convey the paper 6 onto the fixed adsorption placement plate 3. The guiding and correcting device 5 precisely adjusts the paper 6 to ensure that the paper 6 is accurately placed at the designated position. After the paper 6 is placed, the fixed adsorption placement plate 3 adsorbs and positions the paper 6.

[0035] After the paper 6 is positioned, the horizontal moving slide 1 drives the fixed adsorption placement plate 3 above the fixed mounting base 21 to move to the printing area. The printing device 9 performs single-sided printing on the placed paper 6.

[0036] After one side of the paper 6 is printed, the horizontal moving slide 1 drives the folding mounting base 2 back to the folding conversion area. Then, the flipping mounting base 22 performs a flipping motion, driving the movable adsorption placement plate 4 to flip synchronously. The flipping buffer mechanism 23 plays a role to ensure the stability of the flipping process of the flipping mounting base 22. After flipping, the movable adsorption placement plate 4 moves to directly above the fixed adsorption placement plate 3. Subsequently, the flipping mounting base 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 that has been printed on one side, and adsorbs and positions the paper 6. After adsorbing the paper 6, the flipping mounting base 22 resets and just stops in the printing area after resetting.

[0037] After the flipping mounting base 22 resets and stops in the printing area, the printing device 9 prints the other side of the flipped printed paper. At this time, the fixed adsorption placement plate 3 stays in the folding conversion area, and the guiding and correcting device 5 and the feeding device 7 cooperate to place a new printed paper on the fixed adsorption placement plate 3. When the printed paper on the movable adsorption placement plate 4 is double-sided printed, the horizontal moving slide 1 drives the fixed adsorption placement plate 3 to move to the printing area again, and the printing device 9 performs single-sided printing on the newly placed printed paper. At the same time, the discharging device 8 discharges and removes the printed paper that has been double-sided printed on the movable adsorption placement plate 4. This printing platform can effectively reduce the volume of the equipment, lower the production cost, and at the same time ensure the positioning accuracy of the paper 6 and the printing operation efficiency.

[0038] See Figures 1 to 8 As shown, a plurality of first limit mounting grooves 211 are provided on the fixed mounting base 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 base 21. The first clamping mounting mechanism 212 includes an inserting clamping plate 2121 slidably mounted on the fixed mounting base 21. The clamping end of the inserting clamping plate 2121 extends towards the first limit mounting groove 211, and a first spring 2122 is installed between the clamping part of the inserting clamping plate 2121 and the fixed mounting base 21.

[0039] When it is necessary to install and fix the adsorption placement plate 3, the staff adjusts the position of the insertion card board 2121. During this process, the insertion card board 2121 is subjected to an external force, causing the first spring 2122 to be compressed. As a result, the insertion card board 2121 slides away from the first limit installation groove 211, and at this time, the first limit installation groove 211 is in an open state. The staff inserts the clamping end of the fixed adsorption placement plate 3 into the first limit installation groove 211. Subsequently, due to the elastic restoring force of the first spring 2122, after removing the external force on the insertion card board 2121, the first spring 2122 pushes the insertion card board 2121 to move towards the first limit installation groove 211, and the clamping end of the insertion card board 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.

[0040] Through the above-mentioned assembly method in which the first limit installation groove 211 and the first clamping installation mechanism 212 cooperate, when installing the fixed adsorption placement plate 3, by utilizing the elastic deformation and recovery characteristics of the first spring 2122, the insertion card board 2121 realizes the clamping and release of the fixed adsorption placement plate 3, which can effectively improve the convenience of installing 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.

[0041] See Figures 1 to 7 As shown, a plurality of guide posts 222 are provided on the flipping mounting seat 22, and a plurality of lifting mounting plates 223 are installed on the guide posts 222. A downward pressing adjustment device is installed between each lifting mounting plate 223 and the flipping mounting seat 22. The downward pressing adjustment device is used to drive the lifting mounting plate 223 to move up and down. A second clamping installation mechanism 224 is installed on each lifting mounting plate 223, and a plurality of second limit installation grooves 2231 are provided on the lifting mounting plate 223.

[0042] The downward pressing adjustment device is used to drive the lifting mounting plate 223 to move up and down along the guide post 222. Each lifting mounting plate 223 is provided with a plurality of second limit installation grooves 2231 and is installed with a second clamping installation mechanism 224. The second clamping installation mechanism 224 has the same structure as the first clamping installation mechanism 212. The second clamping installation mechanism 224 is used to clamp and install the movable adsorption placement plate 4. In addition, the flipping mounting seat 22 is driven by a rotation driving device 221 to perform a flipping motion. The rotation driving device 221 is a prior art and will not be elaborated here.

[0043] When the movable adsorption placement plate 4 needs to flip and adsorb the paper 6 on the fixed adsorption placement plate 3, the rotation driving device 221 is started to drive the flipping mounting seat 22 to perform a flipping motion. During the flipping process, the flipping buffer mechanism 23 plays a role, effectively ensuring the stability of the flipping and enabling the movable adsorption placement plate 4 to accurately move above the fixed adsorption placement plate 3.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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 .

[0053] 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.

[0054] The top of the fixed adsorption placement plate 3 is provided with a horizontal bearing surface 31, which provides a horizontal placement support plane for the printing paper. The horizontal bearing surface 31 is evenly covered with adsorption holes 32, and these adsorption holes 32 are connected to an external adsorption device through connection means such as pipes. When it is necessary to place the printing paper, under the coordinated action of the guiding and correcting device 5 and the feeding device 7, the paper 6 is conveyed to the horizontal bearing surface 31 of the fixed adsorption placement plate 3. At this time, the adsorption device is activated, and a suction effect is generated through the adsorption holes 32. Utilizing the atmospheric pressure difference, the printing paper is closely attached to the horizontal bearing surface 31, realizing effective adsorption and fixation of the printing paper, ensuring that the paper 6 does not shift during the subsequent printing process, and providing a stable paper 6 placement basis for the printing operation.

[0055] See Figures 1 to 9 As shown, the guiding and correcting device 5 includes a correcting and guiding mechanism 51 on the side of the horizontal moving slide 1. A visual detector 52 and a correcting and pushing device 53 are installed at the guiding end of the correcting and guiding mechanism 51. The visual detector 52 is used to detect the position of the printing paper, and the correcting and pushing device 53 is used to adjust the position of the printing paper.

[0056] When the printing platform needs to perform double-sided printing operations and the feeding device 7 starts to convey the paper 6 to the fixed adsorption placement plate 3, the correcting and guiding mechanisms 51 of the guiding and correcting devices 5 located on both sides of the horizontal moving slide 1 will act first. The guiding end of the correcting and guiding mechanism 51 will be pre-moved to a designated position on the fixed adsorption placement plate 3, and this designated position is set according to the correct placement position of the printing paper on the fixed adsorption placement plate 3. During the conveyance of the paper 6, the correcting and guiding mechanism 51 guides the paper 6, enabling the paper 6 to move along a preset path towards the fixed adsorption placement plate 3, thereby effectively guiding the paper 6 close to the designated position.

[0057] After the feeding device 7 initially places the paper 6 on the fixed adsorption placement plate 3, at this time the paper 6 is located between the two correcting and guiding mechanisms 51. The visual detector 52 installed at the guiding end of the correcting and guiding mechanism 51 starts to work and detects the paper 6 staying at this position. The visual detector 52 will compare and analyze the detected image of the paper 6 with a pre-set standard image or position information to determine whether the paper 6 accurately stays at the designated position on the fixed adsorption placement plate 3.

[0058] If the vision detector 52 detects that the paper 6 is not placed in place, that is, there is a deviation from the preset standard position, then the correction pushing device 53 will be immediately activated. The correction pushing device 53 makes a pushing adjustment to the paper 6. According to the position deviation information of the paper 6 fed back by the vision detector 52, the direction and strength of the pushing are precisely controlled, so that the paper 6 gradually moves to the designated position on the fixed adsorption placement plate 3. Once the paper 6 is adjusted to the correct position, the fixed adsorption placement plate 3 will immediately activate the adsorption function to firmly fix the paper 6 in this position, thus completing the automatic correction process of the entire position of the paper 6.

[0059] See Figures 9 to 11 As shown, the correction guiding mechanism 51 includes a fixed mounting bracket 511 installed on the side of the horizontal moving slide 1. A first linear driver 512 is installed on the fixed mounting bracket 511. The output end of the first linear driver 512 is installed with a telescopic mounting bracket 513. A guiding right-angle rail 514 is slidably installed on the telescopic mounting bracket 513. A second spring 515 is installed between the guiding right-angle rail 514 and the telescopic mounting bracket 513.

[0060] The guiding right-angle rail 514 is provided with a guiding edge and a limiting blocking edge. One end of the limiting blocking edge is provided with a guiding bevel.

[0061] The fixed mounting bracket 511 in the correction guiding mechanism 51 is firmly installed on the side of the horizontal moving slide 1, providing a support foundation for the entire mechanism. The first linear driver 512 is installed on the fixed mounting bracket 511, and the output end of the first linear driver 512 is connected to the telescopic mounting bracket 513. When not working, the telescopic mounting bracket 513 is in the initial position. The guiding right-angle rail 514 is slidably installed on the telescopic mounting bracket 513, and a second spring 515 is installed between the guiding right-angle rail 514 and the telescopic mounting bracket 513. At this time, the second spring 515 is in the natural state.

[0062] When the printing platform needs to perform a duplex printing operation and the feeding device 7 starts to convey the paper 6 to the fixed adsorption placement plate 3, the first linear driver 512 is activated. It drives the telescopic mounting frame 513 to move towards the fixed adsorption placement plate 3. Since the telescopic mounting frame 513 is connected to the guiding right-angle rail 514, the movement of the telescopic mounting frame 513 will drive the guiding right-angle rail 514 to move synchronously. During the movement of the guiding right-angle rail 514, the guiding bevel at one end of its limiting blocking edge will first contact the side of the fixed adsorption placement plate 3. With continuous movement, the guiding right-angle rail 514 is squeezed by the side of the fixed adsorption placement plate 3 and will move upward and squeeze the second spring 515. When the second spring 515 is squeezed, it will produce elastic deformation and store elastic potential energy. Under the action of the elastic force of the second spring 515, the bottom of the guiding right-angle rail 514 will closely fit the top of the fixed adsorption placement plate 3, thus ensuring the stability and accuracy of the guiding right-angle rail 514 in guiding the paper 6 in the subsequent process.

[0063] The guiding right-angle rail 514 is provided with a guiding edge and a limiting blocking edge, where the guiding edge is used to guide the limited movement of the paper 6. When the paper 6 approaches the guiding right-angle rail 514 during conveyance, the guiding edge will contact the paper 6 and apply a lateral guiding force to the paper 6, enabling the paper 6 to move along the path set by the guiding edge, thereby realizing the guiding of the moving direction of the paper 6. The 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 limiting blocking edge will prevent the paper 6 from continuing to move, ensuring that the paper 6 can accurately stay within the designated area of the fixed adsorption placement plate 3. Through the coordinated action of the guiding edge and the limiting blocking edge, the guiding mechanism 51 can effectively guide the paper 6 to move to the designated position, laying a foundation for the subsequent detection of the position of the paper 6 by the vision detector 52 and possible position adjustment, and ensuring the accuracy and reliability of the printing platform during the paper 6 positioning process.

[0064] See Figures 9 to 11 As shown, the correcting pushing device 53 includes a fixed mounting plate 531 installed on the guiding right-angle rail 514. The fixed mounting plate 531 is provided with a limiting sliding groove 5311. A moving slider 533 is installed inside the limiting sliding groove 5311. A second linear driver 532 is also installed on the side of the fixed mounting plate 531. The output end of the second linear driver 532 is connected to the moving slider 533. A third linear driver 534 is installed on the moving slider 533. The output end of the third linear driver 534 is installed with a horizontal fitting plate 535, and the horizontal fitting plate 535 is provided with a plurality of limiting suction cups.

[0065] The fixed mounting plate 531 is provided with a limit sliding groove 5311, and a moving slider 533 is installed inside. The moving slider 533 can slide within the limit sliding groove 5311. A second linear driver 532 is installed on the side of the fixed mounting plate 531, and the output end of the second linear driver 532 is connected to the moving slider 533 for driving the moving slider 533 to move within the limit sliding groove 5311. A third linear driver 534 is installed on the moving slider 533, and its output end is connected to a horizontal fitting plate 535. The horizontal fitting plate 535 is provided with a plurality of limit suction cups. When not working, the third linear driver 534 is in a contracted state, the horizontal fitting plate 535 is at a higher position, the limit suction cups are not in contact with the paper 6, and the second linear driver 532 is also in its initial position, and the moving slider 533 has not displaced.

[0066] When the vision detector 52 detects that the paper 6 is not placed in place and there is a deviation from the preset standard position, the correction pushing device 53 is activated. First, the third linear driver 534 starts to work, driving the horizontal fitting plate 535 to move downward. As the horizontal fitting plate 535 descends, the plurality of limit suction cups gradually approach the surface of the paper 6 until they are in close contact with the paper 6. At this time, the limit suction cups generate an adsorption force, firmly adsorbing the paper 6 on the horizontal fitting plate 535.

[0067] After the limit suction cups adsorb the paper 6, the second linear driver 532 is activated. The second linear driver 532 pushes the moving slider 533 to move within the limit sliding groove 5311. Since the moving slider 533 is connected to the third linear driver 534, the horizontal fitting plate 535, and the adsorbed paper 6, the movement of the moving slider 533 will drive the third linear driver 534, the horizontal fitting plate 535, and the paper 6 to move synchronously. During the movement, the second linear driver 532 will precisely control the direction and force of the movement according to the position deviation information of the paper 6 fed back by the vision detector 52. The precise displacement adjustment of the paper 6 on the fixed adsorption placement plate 3 is realized, so that the paper 6 gradually moves to the preset standard position. When the paper 6 is adjusted to the correct position, the fixed adsorption placement plate 3 activates its adsorption function, firmly fixing the paper 6 at this position.

[0068] The present invention also provides a printing press, which adopts a printing platform.

[0069] Specific working principle: When double-sided printing is required, the horizontal moving slide 1 drives the folding mounting base 2 to move to the folding conversion area. At this time, the guiding and correcting device 5 is activated, and the working end of the guiding and correcting device 5 moves above the fixed adsorption placement plate 3. Subsequently, the guiding and correcting device 5 and the feeding device 7 are activated in coordination to convey the paper 6 onto the fixed adsorption placement plate 3. The guiding and correcting device 5 precisely adjusts the paper 6 to ensure that the paper 6 is accurately placed at the designated position. After the paper 6 is placed, the fixed adsorption placement plate 3 adsorbs and positions the paper 6. After the positioning of the paper 6 is completed, the horizontal moving slide 1 drives the fixed adsorption placement plate 3 above the fixed mounting base 21 to move to the printing area. The printing device 9 performs single-sided printing on the placed paper 6. After one side of the paper 6 is printed, the horizontal moving slide 1 drives the folding mounting base 2 back to the folding conversion area. Then, the flipping mounting base 22 performs a flipping motion, driving the movable adsorption placement plate 4 to flip synchronously. The flipping buffer mechanism 23 plays a role to ensure the stability of the flipping process of the flipping mounting base 22. After flipping, the movable adsorption placement plate 4 moves directly above the fixed adsorption placement plate 3. Subsequently, the flipping mounting base 22 drives the movable adsorption placement plate 4 to descend, so that the adsorption surface of the movable adsorption placement plate 4 fits the top of the printed paper on the fixed adsorption placement plate 3 with one side already printed, and adsorbs and positions the paper 6. After adsorbing the paper 6, the flipping mounting base 22 resets and just stops in the printing area when reset.

[0070] After the flipping mounting base 22 resets and stops in the printing area, the printing device 9 performs printing on the other side of the flipped printed paper. At this time, the fixed adsorption placement plate 3 stays in the folding conversion area, and the guiding and correcting device 5 and the feeding device 7 cooperate to place a new printed paper onto the fixed adsorption placement plate 3. When the double-sided printing of the printed paper on the movable adsorption placement plate 4 is completed, the horizontal moving slide 1 drives the fixed adsorption placement plate 3 to move to the printing area again, and the printing device 9 performs single-sided printing on the newly placed printed paper. At the same time, the discharging device 8 discharges and removes the printed paper that has completed double-sided printing on the movable adsorption placement plate 4. This printing platform can effectively reduce the volume of the equipment, lower the production cost, and at the same time ensure the positioning accuracy of the paper 6 and the printing operation efficiency.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
