Description

Technical Field

[0001] This application relates to the field of digital printing press technology, specifically to an anti-deviation correction component and a high-precision digital printing press. Background Technology

[0002] Digital printing is a technology that uses digital files for direct printing, eliminating the need for traditional plate-making processes. It enables on-demand printing, real-time error correction, and variable data printing. The working principle of a digital printing press typically involves a prepress system and the press itself. The prepress system processes the digital files, while the press directly transfers the image onto the substrate. Depending on the printing mode, digital printing presses can be categorized into several types, including inkjet, thermal transfer, electrostatic (electromagnetic), and digital offset printing.

[0003] Digital printing presses are typically equipped with wide conveyor belts to carry and transport cardboard. The choice of conveyor belt material must consider abrasion resistance, antistatic properties, and ink compatibility. An electric drive system (such as a servo motor) propels the conveyor belt via gears, chains, or belts. This drive system must possess high precision and stability to ensure precise position and speed control of the cardboard during transport.

[0004] After prolonged operation, the internal mechanical structure of the equipment will age. At this time, the equipment will vibrate slightly during operation. During the conveying of cardboard, the cardboard will be slightly displaced on the conveyor belt. This will cause printing misalignment during the subsequent printing process. Utility Model Content

[0005] The purpose of this application is to provide an anti-deviation correction component and a high-precision digital printing machine to solve the problem mentioned in the background art that slight displacement of cardboard on the conveyor belt will cause printing misalignment during subsequent printing on its surface.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] This utility model provides an anti-deviation correction component, including: a fixed frame and a multi-directional limiting structure. The multi-directional limiting structure is disposed above the fixed frame. The multi-directional limiting structure includes a fixed plate fixed on both sides above the fixed frame, a first guide rod welded to both sides of the inner wall of the fixed plate, and a limiting plate slidably connected to both ends of the first guide rod. The limiting plate has several sets of holes evenly spaced inside. The multi-directional limiting structure also has several sets of second guide rods welded to the inner wall of the fixed plate and an elastic sheet disposed below the second guide rod. The second guide rod is disposed through the holes in the limiting plate.

[0008] By adopting the above technical solution, the phenomenon of cardboard deviation can be avoided during the cardboard conveying process.

[0009] Preferably, the multi-directional limiting structure further includes a connecting block welded to the outer wall of the limiting plate, and the connecting block has a vertical threaded hole inside.

[0010] By adopting the above technical solution, the internal structure can move synchronously during the rotation process.

[0011] Preferably, the multi-directional limiting structure also includes a first lead screw that is threaded into the vertical threaded hole of the connecting block, and one end of the first lead screw is attached to the outer wall of the first guide rod.

[0012] By adopting the above technical solution, it is possible to fix the object by squeezing during the movement process.

[0013] Preferably, the multi-directional limiting structure further includes a first "C"-shaped block disposed above the outer wall of the second guide rod and a second "C"-shaped block disposed below the outer wall of the second guide rod. One end of the first "C"-shaped block is provided with a threaded through hole, and one end of the second "C"-shaped block is provided with a threaded groove. The elastic sheet is fixed to the bottom of the second "C"-shaped block.

[0014] By adopting the above technical solution, the outer structure can be moved on the second guide rod by the mutual contact of the first "C" block and the second "C" block.

[0017] In another aspect, this utility model also provides a high-precision digital printing machine, including an anti-deviation correction component as described in any of the above claims. The high-precision digital printing machine further includes a conveying mechanism disposed inside a fixed frame and below an elastic sheet.

[0018] By adopting the above technical solution, the cardboard placed above can be conveyed in an orderly manner.

[0019] Preferably, the high-precision digital printer further comprises: a printing mechanism disposed on the outside of the fixed frame.

[0020] By adopting the above technical solution, the surface of the conveyed cardboard can be printed.

[0021] In summary, this application has the following beneficial effects: by setting a multi-directional limiting structure and adjusting the position of the limiting plate, the cardboard of different sizes can be limited on both sides during the conveying process to avoid deviation. Furthermore, the elastic sheet can deform by its own material to squeeze the top of the cardboard conveyed below, thereby reducing the cardboard from shaking due to the equipment.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0029] Example 1

[0030] Please see Figures 1-4 This embodiment provides a technical solution: an anti-deviation correction component, including: a fixed frame 1 and a multi-directional limiting structure 4;

[0031] The fixed frame 1 provides a stable connection between the internal and external upper structures. The multi-directional limiting structure 4 is located above the fixed frame 1 and can limit and fix the two ends and the top of the cardboard, thereby preventing the cardboard from shifting during movement.

[0032] The multi-directional limiting structure 4 includes a fixing plate 401 fixed on both sides of the upper part of the fixed frame 1. The fixing plate 401 can provide a stable connection between the structures and can be effectively fixed to the fixed frame 1 by bolts. A first guide rod 402 is welded to both sides of the inner wall of the fixing plate 401. The first guide rod 402 can provide stable and continuous horizontal movement of the structure on the rod. Limiting plates 403 are slidably connected to both ends of the first guide rod 402. The limiting plates 403 can limit the two sides of the cardboard and prevent the limiting plates 403 from deviating during movement. The limiting plates 403 have several sets of holes equidistantly opened inside, which can provide through connection of the internal structure, thereby enabling effective movement between the structures.

[0033] A connecting block 404 is welded to the outer wall of the limiting plate 403. The connecting block 404 provides a stable connection between the structures. The connecting block 404 has a vertical threaded hole inside, which allows the internal structure to move vertically synchronously during rotation. A first lead screw 405 is threaded into the vertical threaded hole of the connecting block 404. The first lead screw 405 can move vertically during rotation. One end of the first lead screw 405 is attached to the outer wall of the first guide rod 402. During movement, the first lead screw 405 can press against the outer wall of the first guide rod 402 to achieve an effective fixed connection. Several sets of second guide rods 406 are welded to the inner wall of the fixing plate 401. The second guide rods 406 provide stable horizontal movement for the structure on the rod.

[0034] Furthermore, the second guide rod 406 is inserted through the hole in the limiting plate 403, ensuring it does not affect the movement of the limiting plate 403. A first "C"-shaped block 407 is positioned above the outer wall of the second guide rod 406, with a threaded through hole at one end. This threaded through hole allows the internal structure to move vertically during rotation. A second "C"-shaped block 408 is positioned below the outer wall of the second guide rod 406, with a threaded groove at one end. This threaded groove allows the internal structure to rotate, effectively connecting subsequent structures. When the first "C"-shaped block 407 and the second "C"-shaped block 408 are in contact with each other on their outer walls, their cross-section is "U"-shaped, allowing the second guide rod... 406 stably achieves horizontal movement. Hinges 409 are respectively set at the other end of the outer wall of the first "C" block 407 and the second "C" block 408. The first "C" block 407 and the second "C" block 408 can change their angle through the hinges 409. The second lead screw 410 is fixed in the threaded through hole of the first "C" block 407. When the second lead screw 410 rotates in the threaded through hole of the first "C" block 407, one end of the second lead screw 410 can rotate into the threaded groove of the second "C" block 408, thereby fixing the first "C" block 407 and the second "C" block 408 together. The elastic piece 411, which is bolted to the bottom of the second "C" block 408, can limit the top of the cardboard below, thus achieving an effective limiting effect.

[0035] When the cardboard is placed on the conveyor mechanism 2, the position of the limiting plate 403 on the first guide rod 402 on the inner wall of the fixing plate 401 is adjusted according to the size of the cardboard. When the limiting plate 403 is located on both sides of the cardboard and does not affect the movement of the cardboard, the first lead screw 405 inside the connecting block 404 is turned. During the rotation of the first lead screw 405, the limiting plate 403 can be positioned by pressing and adhering to the outer wall of the second guide rod 406. Several adjustments are still needed. The position of the elastic piece 411 is determined to provide multi-point positioning for the top of the cardboard. By rotating the second screw 410 inside the first "C" block 407, one end of the second screw 410 is no longer inside the second "C" block 408. Then, the first "C" block 407 and the second "C" block 408 are rotated and unfolded through the hinge 409, thereby unlocking the second guide rod 406 and allowing for subsequent changes to the position of the elastic piece 411.

[0036] Example 2

[0037] Please see Figures 1-4This embodiment provides a technical solution: a high-precision digital printing machine, including an anti-deviation correction component as described in any of the above, and the high-precision digital printing machine further includes: a conveying mechanism 2 and a printing mechanism 3;

[0038] The conveying mechanism 2 is located inside the fixed frame 1. The conveying mechanism 2 is driven by a motor to rotate the conveying roller, and a conveyor belt is fitted on the outer wall of the conveying roller. During the rotation of the conveyor belt, it can drive the cardboard placed above to move horizontally. The conveying mechanism 2 is located below the elastic sheet 411. The elastic sheet 411 can squeeze the cardboard above the conveying mechanism 2 during the movement, thereby preventing the cardboard from shifting. The printing mechanism 3 is located outside the fixed frame 1. The printing mechanism 3 uses digital technology to control the laser beam corresponding to the image information to affect the distribution of electrostatic charge on the surface of the photoconductor. Then the charged image attracts toner and is transferred to the substrate. After the toner is shaped, it forms an image. Its color developing medium mainly uses toner and electronic ink.

[0039] The conveying mechanism 2 moves the cardboard placed above to the working area of ​​the printing mechanism 3, where the printing mechanism 3 can print on the surface of the cardboard. After the cardboard is printed, the conveying mechanism 2 can carry the printed cardboard out.

[0040] The implementation principle of the high-precision digital printing machine of this application is as follows:

[0041] First, the conveying mechanism 2 moves the cardboard placed above to the working area of ​​the printing mechanism 3. The printing mechanism 3 can then print on the surface of the cardboard. After the cardboard is printed, the conveying mechanism 2 can then transport the printed cardboard out.

[0042] Secondly, when the cardboard is placed on the conveying mechanism 2, the position of the limiting plate 403 on the first guide rod 402 on the inner wall of the fixing plate 401 is adjusted according to the size of the cardboard. When the limiting plate 403 is located on both sides of the cardboard and does not affect the movement of the cardboard, the first lead screw 405 inside the twisting connecting block 404 is rotated. During the rotation of the first lead screw 405, the limiting plate 403 can be positioned by pressing and fitting against the outer wall of the second guide rod 406.

[0043] Finally, the positions of several sets of elastic pieces 411 need to be adjusted to achieve multi-point positioning of the top of the cardboard. By rotating the second screw 410 inside the first "C" block 407, one end of the second screw 410 is no longer inside the second "C" block 408. Then, the first "C" block 407 and the second "C" block 408 are rotated and unfolded through the hinge 409, thereby unlocking the second guide rod 406 and allowing for subsequent changes to the position of the elastic pieces 411.

[0044] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
