A convenient digital printing quality inspection device

Abstract

This utility model discloses a conveniently installed digital printing quality inspection device, including a bracket and an inspection device body. The bracket is inclined, and the inspection device body is installed at the end of the bracket. A mounting frame is fixedly connected to the upper end of the bracket, and a bolt seat is installed at the lower end of the mounting frame. A rubber roller is rotatably connected inside the bolt seat. This utility model uses components such as a servo motor, a double-ended threaded rod, a slider, a guide plate, and a limiting rod.

Description

Technical Field

[0001] This utility model relates to the field of printing inspection technology, specifically a digital printing quality inspection device that is easy to install. Background Technology

[0002] Digital printing quality inspection is a core component in ensuring the quality of printed materials, and the convenience, stability, and adaptability of the inspection equipment directly affect printing production efficiency and quality control levels. Currently, with the rapid development of digital printing technology, the variety of printed products and substrates has increased, placing higher demands on the universal installation, rapid adjustment, and efficient operation of inspection equipment.

[0003] Common paper guiding mechanisms and anti-wrinkle pressure rollers are mostly rigidly installed and lack self-adjusting capabilities, which can easily lead to paper deviation, wrinkling, or instability in the detection area, thereby affecting imaging and detection accuracy. Therefore, this utility model proposes a digital printing quality detection device that is easy to install, thus solving the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, such as the paper guiding mechanism being prone to deviation, inconvenient adjustment, and the anti-wrinkle roller being prone to wrinkling and having poor adaptability, this invention incorporates an adjustment mechanism with a servo motor and a double-headed threaded rod, and a wrinkling mechanism with a slide bar and a spring. This achieves stable feeding and precise guidance of printing papers of different widths and thicknesses, avoiding paper deviation, wrinkling, and cumbersome adjustments, and ensuring the efficiency and accuracy of printing quality inspection.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a conveniently installed digital printing quality inspection device, comprising a bracket and an inspection device body. The bracket is inclined, and the inspection device body is installed at the end of the bracket. A mounting frame is fixedly connected to the upper end of the bracket, and a bolt seat is installed at the lower end of the mounting frame. A rubber roller is rotatably connected inside the bolt seat. Multiple sets of rotating rollers are equidistantly arranged inside the bracket. Two sets of side plates are installed between the mounting frame and the rotating rollers, both mounted on the end face of the bracket. Two sets of sliding grooves are opened at the upper end of the bracket. Two sets of guide plates are slidably connected inside the bracket. One end of each guide plate is inclined towards the inner wall of the bracket, and the other end slides in the sliding groove. The two sets of guide plates form a funnel shape. An adjustment mechanism is provided between the two sets of side plates. A wrinkling mechanism is installed at the lower end of the mounting frame. Two sets of bolt seats are fixedly connected to the end of the bracket close to the mounting frame.

[0006] Preferably, the adjusting mechanism includes a double-ended threaded rod rotatably connected between two sets of side plates. Two sets of limiting rings are symmetrically arranged on the outer wall of the double-ended threaded rod. Two sets of sliders are installed on the threads of the double-ended threaded rod, and the two sets of sliders are respectively fixedly connected to two sets of guide plates.

[0007] Preferably, a limiting rod is fixedly connected between the two sets of side plates, and both sets of sliders are slidably connected to the outer wall of the limiting rod.

[0008] Preferably, the wrinkling mechanism includes two sets of slide rods slidably connected to the end face of the mounting frame, the ends of the two sets of slide rods being fixedly connected to the end face of the outer frame, and a drive motor being provided on the side wall of the outer frame and coaxially fixedly connected to the rubber roller.

[0009] Preferably, each end of the slide rod is fixedly connected to a limiting block, the radius of the limiting block being larger than the radius of the slide rod, and a spring is sleeved on the outer wall of the slide rod, with both ends of the spring being fixedly connected to the mounting bracket and the limiting block, respectively.

[0010] Preferably, a servo motor is fixedly connected to the outer wall of one of the side plates, and the output shaft of the servo motor is coaxially fixedly connected to the double-threaded rod.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a conveniently installed digital printing quality inspection device, which has the following beneficial effects: 1. This utility model utilizes components such as a servo motor, a double-ended threaded rod, a slider, a guide plate, and a limiting rod. The servo motor drives the double-ended threaded rod to rotate, causing the slider to slide synchronously in the opposite direction along the limiting rod to precisely adjust the spacing between the guide plates. At the same time, the limiting ring on the outer wall of the double-ended threaded rod restricts the sliding range of the slider, and the limiting rod prevents the slider from deflecting as the threaded rod rotates. This achieves stable guidance for printing papers of different widths, eliminating the need for tedious manual disassembly or adjustment of positioning components. It effectively solves the defects of the paper guiding mechanism in the background technology, which easily leads to paper deviation and inconvenient adjustment.

[0012] 2. This utility model utilizes components such as a slide bar, spring, limiting block, outer frame, and drive motor. The elastic force of the spring causes the outer frame to drive the rubber roller to automatically adapt the pressure according to the paper thickness. The drive motor drives the rubber roller to rotate at a uniform speed to maintain a stable paper conveying speed. The limiting block prevents the slide bar from disengaging from the mounting frame, ensuring reliable connection of the mechanism. This prevents paper from wrinkling, breaking, and slipping due to fluctuations in conveying speed or improper pressure. It significantly improves the defects of the anti-wrinkle pressure roller in the background technology, which easily causes paper to wrinkle and has poor adaptability of the pressing structure.

[0015] This utility model provides a technical solution for a conveniently installed digital printing quality inspection device: Please see Figure 1-3 A convenient digital printing quality inspection device includes a bracket 1 and an inspection device body 3. The bracket 1 is inclined, and the inspection device body 3 is installed at the end of the bracket 1. A mounting frame 4 is fixedly connected to the upper end of the bracket 1, and a bolt seat 5 is installed at the lower end of the mounting frame 4. A rubber roller 12 is rotatably connected inside the bolt seat 5. Multiple sets of rotating rollers 2 are equidistantly arranged inside the bracket 1. Two sets of side plates 6 are installed between the mounting frame 4 and the rotating rollers 2, and both are installed on the end face of the bracket 1. Two sets of sliding grooves are opened at the upper end of the bracket 1. Two sets of guide plates 11 are slidably connected inside the bracket 1. One end of each guide plate 11 is inclined towards the inner wall of the bracket 1, and the other end slides in the sliding groove. The two sets of guide plates 11 form a funnel shape. An adjustment mechanism is provided between the two sets of side plates 6. A wrinkling mechanism is installed at the lower end of the mounting frame 4. Two sets of bolt seats 5 are fixedly connected to the end of the bracket 1 close to the mounting frame 4. Furthermore, the inclined end of the two sets of guide plates 11 towards the inner wall of the bracket 1 is adapted to the conveying direction of the multiple sets of rotating rollers 2, which can guide the paper to move smoothly along the conveying path of the rotating rollers 2, and prevent the paper from deviating from the preset trajectory during the inclined conveying process of the bracket 1. The bolt seat 5 at one end of the bracket 1 forms symmetrical support, which further improves the convenience and stability of the overall installation, reduces the shaking of the rubber roller 12 during rotation, and ensures the smoothness of paper conveying, so as to solve the problem that the paper guiding mechanism in the background technology is prone to paper deviation.

[0016] The adjustment mechanism includes a double-threaded rod 9 rotatably connected between two sets of side plates 6. Two sets of limiting rings are symmetrically arranged on the outer wall of the double-threaded rod 9. Two sets of sliders 10 are installed on the threads of the double-threaded rod 9. The two sets of sliders 10 are fixedly connected to two sets of guide plates 11 respectively. Furthermore, the two sets of limiting rings on the outer wall of the double-ended threaded rod 9 are respectively positioned to correspond to the initial adjustment positions of the two sets of sliders 10. This limits the sliding range of the sliders 10 on the double-ended threaded rod 9, preventing the sliders 10 from slipping out of the effective threaded section of the double-ended threaded rod 9 due to excessive sliding. This ensures that when the two sets of sliders 10 drive the guide plate 11 for adjustment, they are always within a reasonable range that can adapt to different paper widths. This avoids the paper being unable to pass through normally due to excessive adjustment of the guide plate 11, further optimizing the adjustment effect of the adjustment mechanism on the guide plate 11 and improving the inconvenience of adjusting the paper guiding mechanism in the background art.

[0017] A limit rod is fixedly connected between the two sets of side plates 6, and both sets of sliders 10 are slidably connected to the outer wall of the limit rod.

[0018] The pleating mechanism includes two sets of slide rods 13 that are slidably connected to the end face of the mounting frame 4. The ends of the two sets of slide rods 13 are fixedly connected to the end face of the outer frame 15. A drive motor is provided on the side wall of the outer frame 15 and is coaxially fixedly connected to the rubber roller 12. Furthermore, the outer frame 15, through the sliding structure formed by the two sets of slide rods 13 and the mounting frame 4, allows the outer frame 15 to drive the rubber roller 12 to automatically adjust its vertical position according to the thickness of the paper. The coaxial fixed connection between the drive motor and the rubber roller 12 ensures that the power output by the drive motor is directly and stably transmitted to the rubber roller 12, so that the rubber roller 12 maintains a uniform rotation speed, avoiding fluctuations in the paper feeding speed caused by uneven rotation speed of the rubber roller 12, thereby reducing the probability of paper wrinkling and solving the problem of paper wrinkling caused by anti-wrinkle pressure rollers in the background art.

[0019] Each end of the slide rod 13 is fixedly connected to a limiting block 14. The radius of the limiting block 14 is larger than the radius of the slide rod 13. A spring 7 is sleeved on the outer wall of the slide rod 13. The two ends of the spring 7 are fixedly connected to the mounting frame 4 and the limiting block 14, respectively. Furthermore, the limiting block 14 at the end of the slide rod 13 can effectively prevent the slide rod 13 from disengaging from the sliding hole of the mounting frame 4, ensuring that the slide rod 13 is always stably connected to the mounting frame 4 and the outer frame 15. At the same time, the elastic force of the spring 7 on the outer wall of the slide rod 13 can be transmitted to the slide rod 13 and the outer frame 15 through the limiting block 14, so that the outer frame 15 drives the rubber roller 12 to always maintain appropriate pressure on the paper, avoiding damage to thin paper due to excessive pressure or slippage of thick paper due to insufficient pressure, improving the adaptability of the crimping mechanism to paper of different thicknesses, and improving the problem of rigid installation and poor adaptability of the pressing structure in the background technology.

[0020] One of the side plates 6 has a servo motor 8 fixedly connected to its outer wall, and the output shaft of the servo motor 8 is coaxially fixedly connected to the double-threaded rod 9.

[0021] In practical use, the working principle of this utility model is as follows: When the operator uses this conveniently installed digital printing quality inspection device, the bracket 1 is set at an angle to assist the paper feeding by gravity. The inspection device body 3 is installed at the end of the bracket 1 and is in the inspection state. Multiple sets of rotating rollers 2 maintain an initial uniform rotation speed. The two sets of guide plates 11 form a funnel shape because one end is inclined towards the inner wall of the bracket 1, which provides a guiding space for the paper to enter the device. This can initially avoid the paper from deviating from the preset feeding path when it first enters, and alleviate the problem that the paper guiding mechanism in the background technology is prone to paper deviation.

[0022] When it is necessary to adapt to printing paper of different widths, the operator starts the servo motor 8 fixed on the outer wall of one of the side plates 6. The output shaft of the servo motor 8 drives the double-headed threaded rod 9, which is fixed on the same axis, to rotate. Since the two sets of sliders 10 are threadedly engaged with the double-headed threaded rod 9, and the two sets of sliders 10 are slidably connected to the outer wall of the limiting rod between the two sets of side plates 6, the rotation of the double-headed threaded rod 9 will drive the two sets of sliders 10 to move synchronously in opposite directions along the axis of the limiting rod, thereby driving the guide plate 11, which is fixedly connected to the slider 10, to slide along the groove at the upper end of the bracket 1, so as to achieve precise adjustment of the distance between the two sets of guide plates 11. At this time, the two sets of limiting rings on the outer wall of the double-threaded rod 9 will limit the sliding range of the slider 10, preventing the slider 10 from slipping out of the effective threaded section of the double-threaded rod 9 due to excessive sliding. This ensures that the guide plate 11 is always within a reasonable range that matches the paper width, eliminating the need for tedious manual disassembly or adjustment of the positioning components. This effectively improves the inconvenience of adjusting the paper guiding mechanism in the prior art. At the same time, the limiting rod can prevent the slider 10 from deflecting when it rotates with the double-threaded rod 9, further ensuring the guiding accuracy of the guide plate 11 for the paper and reducing the risk of deviation during paper feeding.

[0023] After the paper enters the device, it slides smoothly along the funnel-shaped channel formed by the guide plate 11 to the top of multiple sets of rotating rollers 2. The uniform rotation of the rotating rollers 2 drives the paper to be conveyed towards the detection device body 3 at the end of the support 1. When the paper is conveyed to the rubber roller 12 below the mounting frame 4, the creasing mechanism starts to work in coordination: the outer frame 15 is slidably connected to the mounting frame 4 through two sets of sliding rods 13. The two ends of the spring 7 on the outer wall of the sliding rod 13 are fixedly connected to the mounting frame 4 and the limiting block 14, respectively. When the paper passes between the rubber roller 12 and the rotating roller 2, it will generate an upward force on the rubber roller 12, causing the outer frame 15 to drive the sliding rod 13 to slide upward along the end face of the mounting frame 4. The spring 7 is then compressed and generates a reverse elastic force. This force is transmitted to the outer frame 15 and the rubber roller 12 through the limiting block 14 and the sliding rod 13, so that the rubber roller 12 always maintains appropriate pressure on the paper. The limiting block 14 at the end of the slide bar 13 can effectively prevent the slide bar 13 from disengaging from the sliding hole of the mounting frame 4, ensuring the stable connection of the creasing mechanism; the drive motor on the side wall of the outer frame 15 is coaxially fixedly connected to the rubber roller 12. When the drive motor is working, it drives the rubber roller 12 to rotate at a uniform speed, and works in conjunction with the rotating roller 2 to keep the paper at a stable conveying speed, avoiding fluctuations in the paper conveying speed due to uneven rotation speed of the rubber roller 12, thereby reducing the probability of paper wrinkling and solving the problem of paper wrinkling caused by anti-wrinkle pressure rollers in the background technology; and the elastic adjustment function of the spring 7 can automatically adjust the pressure of the rubber roller 12 according to the paper thickness, avoiding damage to thin paper due to excessive pressure or slippage of thick paper conveying due to insufficient pressure, improving the adaptability of the creasing mechanism to paper of different thicknesses, and improving the rigid installation and poor adaptability of the pressing structure in the background technology.

[0024] As the paper is continuously fed, after being precisely guided by the guide plate 11 and stably flattened by the rubber roller 12, the paper smoothly enters the detection area of ​​the detection device body 3 at the end of the support 1. Since the paper does not have obvious deviation, wrinkling or fluctuation in conveying speed during the feeding process, the detection device body 3 can clearly collect information such as color, text, graphics and size on the paper surface, accurately identify printing quality problems such as color deviation, missing strokes in text, surface dirt, and out-of-tolerance dimensions, and ensure detection accuracy.

[0025] During the operation of the device, the operator can observe the paper feeding status and the detection results fed back by the detection device body 3. If necessary, the operator can fine-tune the spacing of the guide plate 11 by using the servo motor 8 or check the elasticity of the spring 7 to ensure the continuous and stable operation of the device.

[0026] In summary, this device, through the coordinated operation of the adjustment mechanism, the wrinkling mechanism, and the conveying components, achieves stable conveying and precise guidance of printing papers of different widths and thicknesses. It effectively solves the problems in the prior art where the paper guiding mechanism easily leads to paper deviation, is inconvenient to adjust, and the anti-wrinkle roller easily causes paper wrinkling and has poor adaptability, thus ensuring the efficiency and accuracy of printing quality inspection.

[0027] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
