Intelligent ink-jet printer for file box printing

Abstract

The invention discloses an intelligent ink-jet printer for file box printing, and relates to the technical field of printers. Due to the fact that paper curls at the printing position, the printing face is uneven, and ink marks after printing are misplaced, the intelligent ink-jet printer for file box printing is matched with a paper jacking plate through the elastic force of a spring, and the plane of the top of the paper jacking plate is matched with side pressing wheels on the two sides, so that when the paper arrives at the ink-jet printing position, the paper can be printed on the paper jacking plate, and the paper can be conveniently printed. When the paper stock is printed, the paper stock is slightly jacked by the material jacking plate, a flat plane is formed at the top of the paper stock, and the situation that when the paper stock is printed, due to the fact that the paper stock is bent at the printing position, ink sprayed out during ink-jet printing cannot make contact with the accurate position, and ink marks of the printed paper stock are misplaced is avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of printers, and particularly to an intelligent inkjet printer for printing file boxes. Background Art

[0002] An inkjet printer is a computer output device that forms text, images, etc. by spraying ink onto paper or other media. A voltage driving device is used to apply a fixed pressure to the ink in the nozzle to make it continuously spray, generating ink droplets. The size and spacing of the ink droplets are controlled, and the typing information from the character generator and analog controller is used to control the control charge to form charged and uncharged ink droplets. Then, the deflection electrode changes the flight direction of the ink droplets, making the ink droplets that need to be typed "fly" onto the paper to form characters and graphics, and the other part of the ink droplets is recovered by the conduit. During the inkjet printing process of an inkjet printer, due to the curling of the paper stock at the printing position, the printing surface becomes uneven, resulting in misalignment of the ink marks after printing. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent inkjet printer for printing file boxes, comprising: A frame body, on the top of which an inkjet mechanism and an inner support plate are installed, and the inner support plate is located inside the inkjet mechanism; On both sides of the top of the frame body, a paper feeding mechanism and a paper discharging mechanism are respectively installed, and the paper discharging mechanism and the paper feeding mechanism are located on both sides of the inner support plate; A rectangular through - slot is formed at the top of the inner support plate, and a bottom support plate is fixedly installed at the bottom of the inner support plate. A through - hole is formed at the center of the bottom of the bottom support plate, and a guide rod is slidably installed at the through - hole of the bottom support plate. The top of the guide rod is fixedly connected to a top cardboard. Side guide shafts are rotatably installed on both sides of the top cardboard. A spring is fixedly installed between the top cardboard and the bottom support plate. By the elastic force of the spring and the cooperation of the top cardboard, using the plane at the top of the top cardboard and the side pressure wheels on both sides, when the paper material reaches the ink - jet printing position, it is slightly lifted by the top - material plate, forming a flat plane at the top of the paper material. This avoids the ink ejected during ink - jet printing being unable to contact the accurate position due to the bending of the paper material at the printing position during printing, resulting in misalignment of the ink marks on the paper material after printing. On both sides of the top of the inner support plate, chute frames are fixedly installed. Plate slots are formed on both sides of the chute frames, and sliding beams are slidably installed at the plate slots of the chute frames. Side pressure wheels are rotatably installed on the opposite surfaces of the sliding beams. Elastic pads are clamped at the plate slots of the chute frames. Through the elastic deformation of the elastic pads themselves, when the paper material is lifted for printing, it cooperates with the side pressure wheels to restrict the paper material on both sides, enabling a flat plane to be smoothly formed when the paper material is lifted. At the same time, the elastic deformation of the elastic pads buffers the restraining force when the paper is subjected to a large pull, preventing the paper material from being torn. The two ends of the opposite surfaces of the sliding beams are in close contact with the outer sides of the elastic pads.

[0004] Preferably, the ink - jet mechanism includes side support blocks. The side support blocks are symmetrically installed at the top of the frame along the axial center position of the frame, and a first motor is fixedly installed on the outer side of the side support blocks. A screw rod is rotatably installed at the center position between the side support blocks, and a sliding shaft is fixedly installed between the side support blocks. The sliding shaft is symmetrically installed on both sides of the screw rod along the axial center position of the side support blocks. The output end of the first motor is fixedly connected to one end of the screw rod. A bottom cushion block is threadedly connected to the outer side of the screw rod. An ink box is fixedly installed at the top of the bottom cushion block, and sleeve plates are fixedly installed on both sides of the bottom of the bottom cushion block. The two ends of the sleeve plates are slidably adapted to the outer side of the sliding shaft. An ink - jet head is fixedly installed on the outer side of the bottom cushion block. The ink - jet head is communicated with the ink box through a pipeline, and the ink - jet head is located directly above the top cardboard.

[0005] Preferably, the paper feeding mechanism includes a support frame. Axial groove plates are provided at the corners of the top of the support frame. A material transfer shaft is rotatably installed on the inner wall of the support frame. The material transfer shafts are uniformly installed along the axial direction inside the support frame. A fixed plate is fixedly connected to the inner wall of the support frame. The fixed plate is located directly below the material transfer shaft. A sliding plate is slidably installed on the top of the fixed plate. By the cooperation of the material transfer shaft and the sliding plate, during the movement of the paper material, the material transfer shaft and the sliding plate contact the paper material on the upper and lower sides of the paper material respectively, so that the frictional forces received on the upper and lower sides of the paper material are different. When the paper material is wrinkled and overlapped, the paper material is flattened during the movement of the paper material, avoiding the printing position error caused by the wrinkles when the paper material is printed. Rubber cushion blocks are fixedly installed at the corners of the bottom of the sliding plate. The opposite surfaces of the rubber cushion blocks are closely attached to the outside of the fixed plate.

[0006] Preferably, pressure shafts are slidably installed at the axial groove plates of the support frame. Top cushion blocks are clamped at the tops of the inner walls of the axial groove plates. The top cushion blocks are made of elastic materials. Due to the elastic characteristics of the top cushion blocks, when the top paper board lifts the paper material, the pressure is transmitted to the rubber cylinder and the pressure shaft through the paper material, causing the pressure shaft to press the top cushion block to deform and move up a certain distance, providing a certain buffer when the top paper board lifts the paper material, and at the same time restricting the paper material to ensure the flatness when the paper material is lifted, and buffering the pulling force on the paper material to avoid the paper material from breaking. The bottom ends of the top cushion blocks are closely attached to both ends of the outside of the pressure shaft. Side support shafts are fixedly installed at both ends of the inner wall of the support frame. The side support shafts are located directly below the pressure shafts. Rubber cylinders are rotatably installed at the central positions of the outside of the pressure shafts.

[0007] Preferably, the paper output mechanism includes an output paper board. Outer support plates are fixedly installed at the central positions on both sides of the output paper board. Second motors are fixedly installed on the outside of the outer support plates. A material transfer shaft is rotatably installed between the outer support plates. One end of the material transfer shaft is fixedly connected to the output end of the second motor. Slide groove blocks are fixedly installed on the outside of the outer support plates. Slide grooves are opened on the outside of the slide groove blocks. Sleeve rods are slidably installed at the slide groove positions of the slide groove blocks. Friction cylinders are fixedly installed on the outside of the sleeve rods. The surfaces of the friction cylinders and the material transfer shafts are both made of rubber materials. By the cooperation of the friction cylinder and the elastic cushion ring, while pressing the paper material, the paper material is restricted to avoid the paper material from being wrinkled, resulting in the uncontrolled movement distance of the paper material driven by the material transfer shaft when the paper material is exported due to the wrinkles, causing the subsequent printing position to be misaligned. The bottoms of the friction cylinder and the material transfer shaft are in contact with the top of the output paper board. Elastic cushion rings are clamped at the slide groove positions of the slide groove blocks. One end of the elastic cushion ring away from the outer support plate is in contact with both ends of the outside of the sleeve rod.

[0008] The present invention provides an intelligent inkjet printer for printing file boxes. It has the following beneficial effects: 1. The intelligent inkjet printer for printing the file box cooperates with the top paper board through the elasticity of the spring, and uses the plane at the top of the top paper board and the side pressure wheels on both sides to slightly lift the paper material when it reaches the inkjet printing position, forming a flat plane on the top of the paper material, so as to avoid the ink ejected during inkjet printing from not contacting the accurate position due to the bending of the paper material at the printing position, resulting in misalignment of the ink marks on the paper material after printing.

[0009] 2. The intelligent inkjet printer for printing the file box, through the elastic deformation of the elastic cushion block itself, cooperates with the restriction of the side pressure wheels on the paper material on both sides when lifting the paper material for printing, so as to smoothly form a plane when lifting the paper material. At the same time, the elastic deformation of the elastic cushion block buffers the restriction force when the paper is subjected to increased pulling, avoiding tearing of the paper material.

[0010] 3. The intelligent inkjet printer for printing the file box, through the cooperation of the material transfer shaft and the sliding plate, during the movement of the paper material, the material transfer shaft and the sliding plate contact the paper material on the upper and lower sides of the paper material respectively, so that the frictional forces on the upper and lower sides of the paper material are different. When the paper material has wrinkles and overlaps, the paper material is flattened during the movement of the paper material, avoiding printing position errors caused by wrinkles during printing.

[0011] 4. The intelligent inkjet printer for printing the file box transfers the pressure to the rubber cylinder and the pressure roller through the paper material, so that the pressure roller compresses the top cushion block to deform and move up a certain distance, providing a certain buffer when the top paper board lifts the paper material, and at the same time restricting the paper material to ensure the flatness when the paper material is lifted, and buffering the pulling force on the paper material to avoid breakage of the paper material.

[0012] 5. The intelligent inkjet printer for printing the file box, through the cooperation of the friction cylinder and the elastic pad ring, while pressing the paper material, restricts the paper material to avoid wrinkles in the paper material, resulting in uncontrolled movement distance of the paper material driven due to wrinkles when the material transfer shaft exports the paper material, causing misalignment of the subsequent printing positions.

Specific implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] The first embodiment, as Figures 1 to 5 shown, the present invention provides a technical solution: An intelligent inkjet printer for printing file boxes, comprising: Frame body 1, on the top of which an inkjet mechanism 3 and an inner support plate 5 are installed, and the inner support plate 5 is located inside the inkjet mechanism 3; On both sides of the top of the frame body 1, a paper feeding mechanism 2 and a paper discharging mechanism 4 are respectively installed, and the paper discharging mechanism 4 and the paper feeding mechanism 2 are located on both sides of the inner support plate 5; A rectangular through - slot is opened at the top of the inner support plate 5, and a bottom support plate 12 is fixedly installed at the bottom of the inner support plate 5. A through - hole is opened at the center position of the bottom of the bottom support plate 12. When the paper material is driven by the paper output mechanism 4 into the bottom of the ink - jet mechanism 3, during the movement of the paper material, the paper material passes through the bottom of the side pressure wheel 6, and the two side pressure wheels 6 press on both sides of the printing position of the paper material. A guide rod 14 is slidably installed at the through - hole of the bottom support plate 12. The top of the guide rod 14 is fixedly connected to a top cardboard 7. Side guide shafts 8 are rotatably installed on both sides of the top cardboard 7. A spring 13 is fixedly installed between the top cardboard 7 and the bottom support plate 12. Slide - groove frames 11 are fixedly installed on both sides of the top of the inner support plate 5. Plate grooves are opened on both sides of the slide - groove frames 11, and slide beams 10 are slidably installed at the plate grooves of the slide - groove frames 11. Side pressure wheels 6 are rotatably installed on the opposite surfaces of the slide beams 10. When the paper material reaches the bottom of the ink - jet mechanism 3, due to the elastic force existing in the initial state of the spring 13, the top cardboard 7 is driven to move upward. Under the restriction of the guide rod 14, the top cardboard 7 moves vertically upward, so that the top cardboard 7 contacts the paper material from the bottom of the paper material and slightly lifts the paper material. Under the lifting force, in cooperation with the restriction of the side pressure wheels 6 on both sides of the paper material, the paper material at the ink - jet printing position is kept flat. Elastic cushion blocks 9 are clamped at the plate grooves of the slide - groove frames 11, and the two ends of the opposite surfaces of the slide beams 10 are in close contact with the outer sides of the elastic cushion blocks 9.

[0017] The ink - jet mechanism 3 includes side support blocks 31. The side support blocks 31 are symmetrically installed at the top of the frame body 1 along the central axis position of the frame body 1. A first motor 32 is fixedly installed on the outer side of the side support blocks 31. A screw rod 33 is rotatably installed at the central position between the side support blocks 31, and a sliding shaft 34 is fixedly installed between the side support blocks 31. The sliding shaft 34 is symmetrically installed on both sides of the screw rod 33 along the central axis position of the side support blocks 31. The output end of the first motor 32 is fixedly connected to one end of the screw rod 33. By driving the screw rod 33 to rotate by the first motor 32, using the threaded connection between the screw rod 33 and the bottom cushion block 36, and in cooperation with the sliding fit between the sliding shaft 34 and the sleeve plate 37, the bottom cushion block 36 is driven to move between the side support blocks 31 during the rotation process, and the position between the ink - jet head 38 and the paper material is adjusted during the movement process. The outer side of the screw rod 33 is threadedly connected with a bottom cushion block 36. An ink box 35 is fixedly installed at the top of the bottom cushion block 36, and sleeve plates 37 are fixedly installed on both sides of the bottom of the bottom cushion block 36. The two ends of the sleeve plates 37 are slidably adapted to the outer side of the sliding shaft 34. An ink - jet head 38 is fixedly installed on the outer side of the bottom cushion block 36. The ink - jet head 38 is communicated with the ink box 35 through a pipeline. The ink in the ink box 35 is introduced into the ink - jet head 38 through the pipeline, and the ink is sprayed on the surface of the paper material by the ink - jet head 38 for ink - jet printing. During printing, in cooperation with the paper output mechanism 4, the paper output mechanism 4 stops driving the paper material to move during the ink - jet process. When the paper material at the bottom of the ink - jet mechanism 3 is completed with ink - jet printing, the paper output mechanism 4 exports the paper material, and the ink - jet head 38 is located directly above the top cardboard 7.

[0018] Second Embodiment. On the basis of the first embodiment, please refer to Figures 6 to 7 As shown, the paper feeding mechanism 2 includes a support frame 21. Axial groove plates are provided at the corners of the top of the support frame 21. A material transfer shaft 24 is rotatably installed on the inner wall of the support frame 21. The material transfer shaft 24 is uniformly installed along the axial direction inside the support frame 21. A fixed plate 29 is fixedly connected to the inner wall of the support frame 21. The fixed plate 29 is located directly below the material transfer shaft 24. A sliding plate 26 is slidably installed on the top of the fixed plate 29. The paper material passes through between the rubber cylinder 25 and the side support shaft 27 on one side and exits between the rubber cylinder 25 and the side support shaft 27 on the other side, and enters below the inkjet mechanism 3. At the same time, when the paper material passes through the paper feeding mechanism 2, through the cooperation of the material transfer shaft 24 and the sliding plate 26, the material transfer shaft 24 presses on the top of the paper material, making the bottom of the paper material closely adhere to the sliding plate 26. Rubber cushion blocks 28 are fixedly installed at the corners of the bottom of the sliding plate 26. The opposite surfaces of the rubber cushion blocks 28 are closely attached to the outside of the fixed plate 29.

[0019] Pressure shafts 22 are slidably installed at the axial groove plate positions of the support frame 21. Top cushion blocks 23 are clamped at the tops of the inner walls of the axial groove plates. The top cushion blocks 23 are made of elastic materials. The bottom ends of the top cushion blocks 23 are closely attached to both ends of the outside of the pressure shafts 22. Side support shafts 27 are fixedly installed at both ends of the inner wall of the support frame 21. When the paper material moves, through the rotation of the material transfer shaft 24, the frictional force between the material transfer shaft 24 and the paper material is changed into rolling frictional force. At the same time, a sliding frictional force is maintained between the sliding plate 26 and the paper material under the restriction of the material transfer shaft 24, making the resistance received by the bottom of the paper material greater than that of the top. When the paper material has wrinkles, using the resistance difference between the upper and lower sides, the wrinkled paper material is flattened during the transmission process. The side support shafts 27 are located directly below the pressure shafts 22. Rubber cylinders 25 are rotatably installed at the central positions of the outside of the pressure shafts 22.

[0020] Third Embodiment. On the basis of the first and second embodiments, please refer to Figure 8As shown in the figure, the paper output mechanism 4 includes a paper output board 41. Outer support boards 42 are fixedly installed at the central positions on both sides of the paper output board 41. Second motors 47 are fixedly installed on the outer sides of the outer support boards 42. A material transfer shaft 48 is rotatably installed between the outer support boards 42. One end of the material transfer shaft 48 is fixedly connected to the output end of the second motor 47. By driving the material transfer shaft 48 to rotate through the second motor 47, and cooperating with the paper output board 41, the paper material between the paper output board 41 and the material transfer shaft 48 is driven under the oppression and rotation of the material transfer shaft 48 to realize the transmission of the paper material. Slide groove blocks 43 are fixedly installed on the outer sides of the outer support boards 42. Slide grooves are opened on the outer sides of the slide groove blocks 43, and sleeve rods 45 are slidably installed at the slide groove parts of the slide groove blocks 43. Friction cylinders 44 are fixedly installed on the outer sides of the sleeve rods 45. The surfaces of the friction cylinders 44 and the material transfer shaft 48 are both made of rubber material. When the paper material is being transmitted, the sleeve rods 45 restricted by the elastic cushion rings 46 drive the friction cylinders 44 to press the paper material, so that the paper material always remains flat under the restriction of the friction cylinders 44 and the elastic cushion rings 46, and the paper material enters the bottom of the material transfer shaft 48 flatly. The paper material is led out flatly by the rotation of the material transfer shaft 48. The bottoms of the friction cylinders 44 and the material transfer shaft 48 are in contact with the top of the paper output board 41. Elastic cushion rings 46 are clamped at the slide groove parts of the slide groove blocks 43. One end of the elastic cushion ring 46 away from the outer support board 42 is in contact with both ends on the outer side of the sleeve rod 45.

[0021] During use, the paper material to be printed penetrates through the paper input mechanism 2, so that the paper material passes through the bottom of the inkjet mechanism 3. The inkjet mechanism 3 performs inkjet printing on the surface of the paper material. After the inkjet printing is completed, the paper material enters the paper output mechanism 4, and the paper output mechanism 4 drives the paper material after the inkjet printing to be led out. At the same time, during the printing process, through intelligent control, the paper output mechanism 4 and the inkjet mechanism 3 cooperate to perform step-by-step printing on the paper material.

[0022] During the printing process, the first motor 32 drives the screw rod 33 to rotate. By utilizing the threaded connection between the screw rod 33 and the bottom cushion block 36, and cooperating with the sliding adaptation between the sliding shaft 34 and the sleeve plate 37, the bottom cushion block 36 is driven to move between the side support blocks 31 during the rotation process, and the position between the inkjet head 38 and the paper material is adjusted during the movement process. At the same time, the ink in the ink tank 35 is introduced into the inkjet head 38 through a pipeline, and the ink is sprayed on the surface of the paper material through the inkjet head 38 for inkjet printing. During printing, in cooperation with the paper output mechanism 4, the paper output mechanism 4 stops driving the paper material to move during the inkjet process. When the paper material at the bottom of the inkjet mechanism 3 completes the inkjet printing, the paper output mechanism 4 leads out the paper material.

[0023] During the inkjet printing process, when the paper material is driven by the paper output mechanism 4 into the bottom of the inkjet mechanism 3, during the movement of the paper material, the paper material passes through the bottom of the side pressure wheels 6, and the two side pressure wheels 6 press on both sides of the printing position of the paper material. At the same time, when the paper material reaches the bottom of the inkjet mechanism 3, the elastic force existing in the initial state of the spring 13 drives the top paper board 7 to move upward. Under the restriction of the guide rod 14, the top paper board 7 moves vertically upward, so that the top paper board 7 contacts the paper material from the bottom of the paper material and slightly lifts the paper material. Under the lifting force, in cooperation with the restriction of the side pressure wheels 6 on both sides of the paper material, the paper material at the inkjet printing position is kept flat.

[0024] In the paper feeding mechanism 2, the paper material passes through between the rubber cylinder 25 and the side support shaft 27 on one side and exits between the rubber cylinder 25 and the side support shaft 27 on the other side, and enters below the inkjet mechanism 3. At the same time, when the paper material passes through the paper feeding mechanism 2, through the cooperation of the material transfer shaft 24 and the sliding plate 26, the material transfer shaft 24 presses on the paper material at the top of the paper material, so that the bottom of the paper material closely adheres to the sliding plate 26. At the same time, when the paper material moves, through the rotation of the material transfer shaft 24, the frictional force between the material transfer shaft 24 and the paper material is changed into rolling frictional force. At the same time, there is a sliding frictional force between the sliding plate 26 and the paper material under the restriction of the material transfer shaft 24, so that the resistance received by the bottom of the paper material is greater than that of the top. When the paper material has wrinkles, using the resistance difference between the upper and lower sides, the wrinkled paper material is flattened during the transmission process.

[0025] In the paper output mechanism 4, the second motor 47 drives the material transfer shaft 48 to rotate, and in cooperation with the paper output board 41, the paper material between the paper output board 41 and the material transfer shaft 48 is driven to move under the oppression and rotation of the material transfer shaft 48. At the same time, when the paper material is being transmitted, the sleeve rod 45 restricted by the elastic cushion ring 46 drives the friction cylinder 44 to press on the paper material, so that the paper material is always kept flat under the restriction of the friction cylinder 44 and the elastic cushion ring 46, and the paper material enters the bottom of the material transfer shaft 48 flatly, and the paper material is flatly exported by the rotation of the material transfer shaft 48.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
