Description

Technical Field

[0001] This utility model relates to the technical field of paper couplet printing equipment, and in particular to a paper couplet printing equipment. Background Technology

[0002] Paper couplets are a traditional Chinese New Year decoration, typically consisting of two printed or handwritten couplets hung on either side of a door frame to express blessings, prayers, and ward off evil spirits for the New Year. With technological advancements, modern paper couplets are mostly produced using printing techniques, with common methods including offset printing and screen printing. Offset printing presses transfer ink to paper via a printing plate, enabling large-scale, efficient production of couplets, while screen printing presses are often used to print special patterns or gold powder decorations.

[0003] In the prior art, a couplet printing device with publication number "CN218876612U" includes: a support, a box fixedly installed on the top of the support, a lifting mechanism including a groove formed on the top of the box, a toothed plate slidably connected inside the groove, a printing mold fixedly installed on the bottom of the toothed plate, a moving mechanism including a slide plate fixedly installed on the inner top wall of the printing mold, a slider slidably connected inside the slide plate, a brush plate fixedly installed on the bottom of the slider, a pressing mechanism including two electric telescopic rods fixedly installed on the inner top wall of the box, a retraction mechanism including a first fixed frame fixedly installed on one side of the box, a conveying mechanism including multiple conveying rollers slidably connected from left to right on both sides of the inner wall of the box, and a drying mechanism including a drying box fixedly installed on the inner side wall of the box.

[0004] The basic principle of screen printing is that a brush pushes dye onto the screen surface, and the screen then transfers the dye to the paper. The brush is driven by a screw to reciprocate, and the dye, propelled by the brush, is printed onto the screen surface through the fine openings of the screen. In this process, the brush's role is to evenly distribute the dye onto the screen surface, thus achieving printing. However, when the brush pushes dye to one side of the screen during its movement, the other side of the brush is left without dye during its return phase. This means that there isn't enough dye to redistribute onto the screen during the return process, affecting the subsequent printing effect. In other words, the brush's reciprocating motion only pushes dye to one side, but when the brush returns to its original position, there is no dye on the other side, causing subsequent printing to be disrupted and preventing a continuous and uniform printing effect. Summary of the Invention

[0005] The main purpose of this invention is to provide a paper couplet printing device that can stably and continuously carry out printing operations and improve printing results.

[0006] To achieve the above objectives, this utility model proposes a paper couplet printing device, comprising:

[0007] A transport device used for transporting paper couplets;

[0008] A screen printing housing is connected to the upper side of the transmission device. A guide groove is provided on the upper side of the screen printing housing. A screen printing template is detachably and fixedly connected inside the screen printing housing.

[0009] A transmission plate is slidably connected inside the screen printing housing, and a receiving groove is provided on the transmission plate.

[0010] The slider slides against the inner wall of the screen printing housing, and a groove is provided on the slider.

[0011] The sliding column has its body abutting against the inner wall of the sliding groove and its two ends abutting against the inner wall of the guide groove and the inner wall of the receiving groove, respectively.

[0012] A drive assembly is used to drive the slider to reciprocate within the screen printing housing;

[0013] The flipping component is used to drive the screen printing housing to move up and down to complete the printing operation of the couplets;

[0014] The receiving plate is used to limit and support the operation of the drive assembly and the flipping assembly.

[0015] In one possible implementation, the driving component includes:

[0016] A drive screw, which is rotatably connected to the screen printing housing;

[0017] The drive block is threadedly connected to the drive screw, fixedly connected to the transmission plate, and slides against the lower side of the receiving plate.

[0018] A drive motor is fixedly connected to one side of the screen printing housing, and the drive shaft of the drive motor is coaxially and fixedly connected to the drive screw.

[0019] In one possible implementation, the flipping component includes:

[0020] A supporting block, which is fixedly connected to the transmission device;

[0021] A limiting block is fixedly connected to a supporting block. A transmission block is slidably connected inside the limiting block. A flipping block is fixedly connected to the transmission block. A support block is rotatably connected to one end of the flipping block away from the transmission block. The support block is fixedly connected to the receiving plate.

[0022] A limiting plate is fixedly connected to the side of the limiting block away from the transmission block, and a flip plate is slidably connected to the limiting plate. The flip plate is coaxially fixedly connected to the support block.

[0023] A drive cylinder is fixedly connected to a bearing block, and the extension shaft of the drive cylinder is fixedly connected to a transmission block.

[0024] In one possible implementation, the limiting plate has a flipping groove, and the flipping plate abuts against the inner wall of the flipping groove.

[0025] In one possible implementation, the limiting block is threaded with an adjusting screw to limit the flip angle of the screen-printed housing.

[0026] In one possible implementation, guide blocks are fixedly connected to both sides of the screen printing housing.

[0027] In one possible implementation, the screen printing housing has a snap-fit ​​groove, and the screen printing template snaps into the snap-fit ​​groove.

[0028] In this invention, the driving component stably drives the slider to reciprocate within the inner wall of the screen printing housing. The slider slides along the guide groove via a sliding column. The guide groove includes two upward-facing planes and one plane parallel to the bottom wall of the screen printing housing. When the slider slides along the plane parallel to the bottom wall of the screen printing housing, it stably squeezes the dye, allowing the dye to be stably printed onto the paper couplet below the screen printing housing through the screen printing template. Then, when the slider carries the dye and moves along the guide groove to one side of the guide block, the slider slides in the upward section of the guide groove via the sliding column. Due to the slider's own gravity, the distance between the side closer to the dye and the axis of the sliding column is less than the distance between the side farther from the dye and the axis of the sliding column. This asymmetrical arrangement causes the slider to tilt during the sliding process, with the side closer to the dye lifting upwards. This tilting effect causes the dye to flow along the inclined surface of the guide block under the action of gravity, driven by the slider. It helps the dye to flow and distribute evenly, allowing the dye to move to the other side of the slider. When the slider is reset, the printing operation can continue. The flipping component can drive the screen printing housing to move vertically up and down, which is used to continuously print paper couplets transported on the conveyor device, improving printing efficiency. When the user needs to change the printed pattern, the flipping component can be further driven, which will drive the screen printing housing to flip after moving up a sufficient distance, making it convenient for the user to disassemble and assemble the screen printing housing and the screen printing template, thus improving user convenience.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] Example

[0040] Reference Figures 1 to 5This utility model proposes a paper couplet printing device, including a support plate 11, a transmission device 1, a screen printing housing 11, a transmission plate 13, a slider 14, a sliding column 15, a receiving plate 16, a driving assembly, and a flipping assembly. The transmission device 1 is used to transport the paper couplets. The screen printing housing 11 is connected to the upper side of the transmission device 1. A guide groove 111 is provided on the upper side of the screen printing housing 11. A screen printing template 12 is detachably fixedly connected inside the screen printing housing 11. The screen printing template 12 can be quickly installed on the screen printing housing 11 by snap-fit ​​or threaded connection. The transmission plate 13 slides... The sliding connection is located inside the screen printing housing 11. The transmission plate 13 has a receiving groove 131. The slider 14 slides and abuts against the inner wall of the screen printing housing 11. The slider 14 has a sliding groove 141. The body of the sliding column 15 abuts against the inner wall of the sliding groove 141 and its two ends abut against the inner wall of the guide groove 111 and the inner wall of the receiving groove 131, respectively. The driving component is used to drive the slider 14 to slide back and forth in the screen printing housing 11. The flipping component is used to drive the screen printing housing 11 to move up and down to complete the printing operation of the couplet. The receiving plate 16 is used to limit and support the operation of the driving component and the flipping component.

[0041] The drive assembly stably drives the slider 14 to reciprocate within the inner wall of the screen printing housing 11. The slider 14 slides along the guide groove 111 via the slide post 15. The guide groove 111 includes two upward-facing planes and one plane parallel to the bottom wall of the screen printing housing 11. When the slider 14 slides along the plane parallel to the bottom wall of the screen printing housing 11, it stably squeezes the dye, allowing the dye to be stably printed onto the paper couplet below the screen printing housing 11 through the screen printing template 12. Then, when the slider 14, carrying the dye, moves along the guide groove 111 towards the guide block 112 on one side, the slider 14 slides in the upward section of the guide groove 111 via the slide post 15. Due to the weight of the slider 14 itself, the distance between the side closer to the dye and the axis of the slide post 15 is smaller than the distance between the side farther from the dye and the axis of the slide post 15. The asymmetrical arrangement of the distance between them causes the slider 14 to tilt during sliding, with the side closer to the dye lifting upwards. This tilting effect allows the dye to flow along the inclined surface of the guide block 112 under the action of gravity, driven by the slider 14. This helps the dye to flow and distribute evenly, allowing it to move to the other side of the slider 14. This makes it easier for the slider 14 to reset and continue printing. The flipping component can drive the screen printing housing 11 to move vertically up and down, enabling continuous printing of paper couplets transported on the conveyor device 1, improving printing efficiency. Furthermore, when the user needs to change the printed pattern, the flipping component can be further driven, causing the screen printing housing 11 to flip after moving up a sufficient distance. This facilitates the user's disassembly and assembly of the screen printing housing 11 and the screen printing template 12, improving user convenience.

[0042] Reference Figure 1 and Figures 3 to 5 The driving components include:

[0043] Drive screw 21 is rotatably connected to screen printing housing 11;

[0044] Drive block 22 is threadedly connected to drive screw 21, drive block 22 is fixedly connected to transmission plate 13, and drive block 22 slides and abuts against the lower side of support plate 16.

[0045] The drive motor 23 is fixedly connected to one side of the screen printing housing 11, and the drive shaft of the drive motor 23 is fixedly connected to the drive screw 21 coaxially.

[0046] The drive assembly stably drives the drive block 22 to reciprocate via the drive motor 23. The drive block 22, with the limiting function of the receiving plate 16, ensures stability during reciprocating sliding and prevents deviation. Due to the stable movement of the drive block 22, it effectively drives the slider 14 to reciprocate smoothly. Automated drive significantly reduces the need for manual operation, lowers labor intensity, and through precise control, ensures that the slider 14 can perform stable and accurate reciprocating motion during printing. This automated control method avoids errors that may occur during manual operation, improving consistency and accuracy in the printing process. The stable movement of the slider 14 maintains stable printing results, avoiding printing quality problems caused by unstable or uneven movement. The entire printing process is more efficient, ensuring the accuracy and consistency of each print, thereby improving the final product's printing effect.

[0047] Reference Figures 1 to 2 The flipping component includes:

[0048] The moving block 31 is fixedly connected to the transmission device 1;

[0049] A limiting block 32 is fixedly connected to the supporting block 31. A transmission block 33 is slidably connected inside the limiting block 32. A flipping block 34 is fixedly connected to the transmission block 33. A support block 35 is rotatably connected to one end of the flipping block 34 away from the transmission block 33. The support block 35 is fixedly connected to the receiving plate 16.

[0050] Limiting plate 36 is fixedly connected to the side of limiting block 32 away from transmission block 33. A flip plate 37 is slidably connected on the limiting plate 36. The flip plate 37 is coaxially fixedly connected to the support block 35.

[0051] Drive cylinder 38 is fixedly connected to bearing block 31, and the telescopic shaft of drive cylinder 38 is fixedly connected to transmission block 33.

[0052] The flipping component can drive the screen printing housing 11 to move vertically up and down, which is used to continuously print paper couplets transported on the transmission device 1, thereby improving printing efficiency. When the user needs to change the printed pattern, the flipping component can be further driven, thereby driving the screen printing housing 11 to flip after moving up a sufficient distance, which makes it convenient for the user to disassemble and assemble the screen printing housing 11 and the screen printing template 12, thus improving the user's convenience.

[0053] Reference Figures 1 to 2 The limiting plate 36 has a flip groove 361, and the flip plate 37 abuts against the inner wall of the flip groove 361.

[0054] The drive cylinder 38 pushes the transmission block 33 upward, thereby causing the flip plate 37 to slide along the inner wall of the flip groove 361. When the cylinder 38 extends or retracts, its stroke distance directly affects the sliding distance of the flip plate 37. The flip plate 37 is connected to the screen printing housing 11 through the support block 35. As the flip plate 37 slides, the screen printing housing 11 also flips. By controlling the extension and retraction stroke of the drive cylinder 38, the sliding distance of the flip plate 37 can be precisely adjusted, thereby controlling the flip angle of the screen printing housing 11. This provides precise flip control, ensuring that the screen printing housing 11 can be accurately flipped to the predetermined angle as needed. This not only improves the operability and flexibility of the equipment, but also allows for adjustment of the flip angle according to different printing needs, ensuring the accuracy and consistency of screen printing operations. Meanwhile, the flip groove 361 consists of two flat sections and one curved section, so when the flip plate 37 slides upward along the flat surface of the flip groove 361, the flip plate 37 will not rotate, that is, the screen printing housing 11 remains parallel and moves upward. This allows the paper couplets printed below the screen printing housing 11 to be moved by the transmission device 1 for daily use.

[0055] Reference Figures 1 to 2 The limiting block 32 is threaded with an adjusting screw 39, which is used to limit the flipping angle of the screen printing housing 11.

[0056] By adjusting the relative tightening distance between the screw 39 and the upper side of the limit block 32, the driving stroke of the drive cylinder 38 can be effectively limited, thereby controlling the flipping angle of the screen printing housing 11. The upward movement distance of the transmission block 33 is limited by the tightening distance of the adjusting screw 39, that is, the flipping angle of the screen printing housing 11 is limited by the tightening distance of the adjusting screw 39. Users can control the flipping angle of the screen printing housing 11 by adjusting the tightening distance of the screw 39, which facilitates the user's disassembly and assembly of the screen printing housing 11 and the screen printing template 12.

[0057] Reference Figures 1 to 3 Guide blocks 112 are fixedly connected to both sides inside the screen printing housing 11;

[0058] Two guide blocks 112 are installed on both sides of the screen printing housing 11 to guide the flow direction of the dye. When the slider 14 carries the dye and moves along the guide groove 111 inside the screen printing housing toward one of the guide blocks 112, the slider 14 slides smoothly in the guide groove 111 via the slide post 15. However, due to the gravity of the slider 14, the distance between the side closer to the dye and the axis of the slide post 15 is less than the distance between the side farther from the dye and the axis of the slide post 15. This asymmetrical arrangement causes the slider 14 to tilt during the sliding process, with the side closer to the dye lifting upwards. The tilting effect causes the dye to flow along the inclined surface of the guide block 112 under the action of gravity, driven by the slider 14. This facilitates the uniform flow and distribution of dye, allowing the dye to move to the other side of the slider 14. This makes it easier to continue printing when the slider 14 is reset. In addition, when the slider 14 is reset, the guide block 112 supports the slider 14, allowing the slide column 15 to move stably from one side of the slide groove 141 to the other side, thereby driving the slider 14 to slide. At this time, the downward end of the slider 14 is in contact with the dye, which improves the squeezing effect on the dye, thus improving the printing effect.

[0059] Reference Figure 3 and 5 The screen printing housing 11 has a snap-fit ​​groove 113, and the screen printing template 12 is snapped into the snap-fit ​​groove 113.

[0060] Users can easily install or remove the screen printing template 12 from the screen printing housing 11. This design not only improves operational flexibility and efficiency but also simplifies the replacement of different screen printing templates 12. Each screen printing template 12 can be customized according to specific patterns or designs, allowing users to quickly switch to a suitable template based on production needs to achieve printing of different styles or colors. When frequent template changes are required, traditional fixed template installation methods may lead to long downtime, while the detachable design can shorten this switching process, thereby reducing unnecessary time waste. Furthermore, this design also improves the adaptability of the equipment, allowing users to flexibly select and adjust templates according to different production tasks, fully utilizing the versatility of the screen printing equipment.
