Description

Technical Field

[0001] This utility model relates to the field of digital printing quality inspection technology, specifically to a digital printing quality inspection agency. Background Technology

[0002] With the rapid development of digital printing technology, its application in the printing industry is becoming increasingly widespread. Compared with traditional printing, digital printing has advantages such as personalized customization and short printing cycle. However, during the digital printing process, due to the influence of equipment precision, ink performance, environmental factors, etc., printed products are prone to various quality problems.

[0003] In most existing digital printed materials, color difference issues cause the printed colors to mismatch with the design, affecting the visual effect; ink spots detract from the aesthetics of the printed material; and misregistration can cause the printed pattern to be misaligned, seriously affecting product quality. Currently, traditional digital printing quality inspection methods mostly rely on manual visual inspection. This method is not only inefficient but also highly susceptible to the subjective factors of the inspectors, easily leading to missed or false inspections, and cannot meet the diverse needs of digital printing quality inspection. Therefore, a new method for digital printing quality inspection is proposed. Utility Model Content

[0004] This invention provides a digital printing quality inspection mechanism that automates the inspection of digital printed materials, saves manpower, improves inspection efficiency, and allows for precise adjustment of the clamping force to adapt to the clamping requirements of printed materials of different thicknesses. This ensures that the digital printed materials do not move during the inspection process, thus preventing errors in the inspection data and making the inspection data more accurate.

[0005] This utility model provides the following technical solution: a digital printing quality inspection mechanism, including a bracket, a plurality of transmission rollers are connected to the inner wall of the bracket, and two connecting rods are fixedly connected to the inner walls of the two brackets at the bottom positions of the plurality of transmission rollers.

[0006] Two fixed bases are fixedly connected to one side of the outer wall of each of the two brackets. A second drive motor is fixedly connected to the top of the two fixed bases on one side. The output end of the second drive motor is connected to a transmission gear set. Both ends of the bottom of the transmission gear set are fixedly connected to threaded rods.

[0007] As a preferred technical solution of this utility model, the outer walls of both threaded rods are penetrated by fixed bases, and the outer walls of both threaded rods are connected to transmission blocks.

[0008] As a preferred technical solution of this utility model, the two ends of the outer walls of the plurality of transmission blocks are slidably connected to limit rods, and the plurality of transmission blocks are grouped in pairs, with a clamping rod fixedly connected between each group of transmission blocks.

[0009] As a preferred embodiment of this utility model, the bottom ends of the two clamping rods are fixedly connected to bottom spring rods, and the bottom ends of the multiple bottom spring rods are fixedly connected to multiple clamping discs, all of which are located at the top of the transmission roller.

[0013] Compared with the prior art, this utility model provides a digital printing quality inspection agency, which has the following beneficial effects:

[0014] 1. This digital printing quality inspection mechanism, through the setting of a printing clamping and fixing system, can stably clamp the printing material onto the drive roller with appropriate force when the clamping plate contacts the printing material, based on the different thicknesses and sizes of the printing material. Since the surface of the clamping plate is made of soft silicone material, it can provide sufficient clamping force to ensure that the printing material does not move during the inspection process, and avoid damage to the surface of the printing material. Furthermore, by controlling the rotation angle and number of revolutions of the drive motor, the magnitude of the clamping force can be precisely adjusted to adapt to the clamping requirements of printing materials of different thicknesses.

[0015] 2. This digital printing quality inspection mechanism uses a scanner mounted on a manually rotated threaded seat. The internal thread structure of the seat allows for fine-tuning of the scanner's height. After precise adjustments to angle and height, the scanner can quickly and accurately capture image details on the surface of the printed material. During the transport of the printed material, the drive motor continuously operates, moving the scanner along the transport direction to perform a comprehensive scan and inspection. The image data collected by the scanner is transmitted in real-time to the image processing system via a dedicated data transmission line for automated inspection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a digital printing quality inspection mechanism, including a support 1. Multiple transmission rollers 2 are connected to the inner wall of the support 1. Two connecting rods 3 are fixedly connected to the inner walls of the two supports 1 at the bottom of the multiple transmission rollers 2. A connecting frame 4 is fixedly connected to the top of the two supports 1. A drive motor 5 is fixedly connected to one side of the outer wall of the connecting frame 4. A threaded rod 6 is fixedly connected to the output end of the drive motor 5. A transmission block 7 is connected to the outer wall of the threaded rod 6.

[0023] Two fixed bases 9 are fixedly connected to one side of the outer wall of each of the two brackets 1. A drive motor 2 10 is fixedly connected to the top of the two fixed bases 9 on one side. The output end of the drive motor 2 10 is connected to the transmission gear set 17. Threaded rods 2 11 are fixedly connected to both ends of the bottom end of the transmission gear set 17.

[0024] Specifically, this digital printing quality inspection mechanism uses a support frame 1 as its foundation, with transmission rollers 2 responsible for transporting printed materials. A drive motor 5, threaded rod 6, transmission block 7, and limit rod 8 form the scanner's horizontal movement adjustment system. A drive motor 10, transmission gear set 17, threaded rod 11, transmission block 12, limit rod 13, clamping rod 15, bottom spring rod 14, and clamping plate 16 constitute the printed material clamping and fixing system. A connecting seat 18, rotating frame 19, threaded seat 20, scanner 21, and electric pump 22 form the scanner's angle and height adjustment system. These systems work together to achieve stable clamping of printed materials during transport and to perform comprehensive, high-precision quality inspection of the printed materials using the scanner. The support frame 1 is made of high-strength aluminum alloy, providing stable support for the entire inspection mechanism. Multiple transmission rollers 2 are connected to the inner wall of the support frame 1 via bearings. The surface of the transmission rollers 2... Made of non-slip rubber, it increases friction with the printed material, ensuring smooth transport. Two connecting rods 3 are fixedly connected to the inner wall of the bracket 1 and located at the bottom of the transmission roller 2, providing auxiliary support and enhancing the overall stability of the bracket 1. The connecting frame 4 is fixed to the top of the two brackets 1, providing a mounting base for components such as the drive motor 5 and the threaded rod 6. Its structural design ensures the stability of the center of gravity after the upper components are installed. The threaded rod 6 is fixedly connected to the output end of the drive motor 5. The transmission block 7 is connected to the threaded rod 6 through internal threads. When the drive motor 5 drives the threaded rod 6 to rotate, the transmission block 7 can move linearly along the axis of the threaded rod 6. The limiting rod 8 is fixed on the connecting frame 4 and passes through the transmission block 7, serving as a guide and limiting element to prevent the transmission block 7 from shifting or rotating during movement, ensuring the stability and accuracy of the horizontal movement of the scanner 21.

[0025] In this embodiment, the outer walls of both threaded rods 11 are penetrated by fixed bases 9, and the outer walls of both threaded rods 11 are connected to transmission blocks 12.

[0026] Specifically, the fixed base 9 is made of cast iron and is fixed to the outer wall of the bracket 1 with bolts, providing stable support for components such as the second drive motor 10 and the second threaded rod 11. The second drive motor 10 drives the transmission gear set 17, which can stably transmit the power of the second drive motor 10 to the second threaded rod 11 and realize the speed adjustment.

[0027] In this embodiment, the two ends of the outer walls of the multiple transmission blocks 12 are slidably connected to limit rods 13, and the multiple transmission blocks 12 are in pairs, with clamping rods 15 fixedly connected between each pair of transmission blocks 12.

[0028] Specifically, two threaded rods 11 pass through the fixed base 9, and the transmission block 12 is connected to the threaded rods 11 through internal threads. Driven by the threaded rods 11, it moves axially. The limiting rod 13 is fixed inside the fixed base 9 and passes through both ends of the transmission block 12, playing a guiding and limiting role, ensuring that the transmission block 12 moves smoothly and preventing deviation.

[0029] In this embodiment, the bottom ends of the two clamping rods 15 are fixedly connected to bottom spring rods 14, and the bottom ends of the multiple bottom spring rods 14 are fixedly connected to multiple clamping discs 16, all of which are located at the top of the transmission roller 2.

[0030] Specifically, multiple transmission blocks 12 are arranged in pairs, and each pair of transmission blocks 12 is fixedly connected to a clamping rod 15. The bottom spring rod 14 of the clamping rod 15 is fixed to the bottom end of the clamping rod 15. The spring inside the spring rod is made of high-strength spring steel. The clamping plate 16 is fixed to the bottom end of the bottom spring rod 14. The surface of the clamping plate 16 is made of soft silicone material, which can avoid damage to the printed matter when clamping it. When the drive motor 10 drives the threaded rod 11 to rotate, causing the transmission block 12 to move, the clamping rod 15, the bottom spring rod 14 and the clamping plate 16 can stably clamp the printed matter on the transmission roller 2.

[0031] In this embodiment, the top of the transmission block 7 is slidably connected to the limit rod 8, and a connecting seat 18 is fixedly connected to one side of the outer wall of the transmission block 7.

[0032] Specifically, the connecting seat 18 is fixed to one side of the outer wall of the transmission block 7, providing an installation base for components such as the rotating frame 19 and the threaded seat 20.

[0033] In this embodiment, a rotating frame 19 is rotatably connected to the inner wall of the connecting seat 18, a threaded seat 20 is fixedly connected to the bottom end of the rotating frame 19, and a scanner 21 is rotatably connected to the inner wall of the threaded seat 20.

[0034] Specifically, the rotating frame 19 is rotatably connected to the inner wall of the connecting seat 18 via a bearing, enabling 360° rotation and flexible adjustment of the detection angle of the scanner 21. The threaded seat 20 is fixed to the bottom of the rotating frame 19 and has a threaded hole inside for mounting the scanner 21. The height of the scanner 21 can be finely adjusted by rotating it.

[0035] In this embodiment, an electric pump 22 is rotatably connected to the bottom end of the rotating frame 19, and the end of the electric pump 22 away from the rotating frame 19 is rotatably connected to one side of the connecting seat 18.

[0036] Specifically, during the inspection process, the extension and retraction of the electric pump 22 can be adjusted through the control system according to the different inspection requirements of the printed materials, so that the scanner 21 can inspect the printed materials at the optimal angle and height, ensuring comprehensive inspection without blind spots.

[0037] The working principle and usage process of this utility model are as follows: During use, the printed material to be inspected is placed on the transmission roller 2. The transmission roller 2 begins to rotate, driving the printed material forward. When the printed material reaches the designated inspection position, the drive motor 10 starts, driving the threaded rod 11 to rotate via the transmission gear set 17. The rotation of the threaded rod 11 causes the transmission block 12 to move axially under the guidance of the limit rod 13, driving the clamping rod 15, the bottom spring rod 14, and the clamping plate 16 to move towards the printed material. Under the elastic action of the bottom spring rod 14, the clamping plate 16 stably clamps the printed material onto the transmission roller 2, ensuring that the printed material does not move during inspection. The drive motor 5 starts, driving the threaded rod 6 to rotate, causing the transmission block 7 to move horizontally under the guidance of the limit rod 8, thereby driving the connecting seat 18 to rotate. The frame 19, threaded seat 20, and scanner 21 are moved to a suitable starting detection position above the printed matter. According to the detection requirements of the printed matter, the electric pump 22 is controlled to extend and retract through the control system. The electric pump 22 drives the rotating frame 19 to rotate around the connecting seat 18, adjusting the detection angle of the scanner 21. At the same time, the height of the scanner 21 on the threaded seat 20 is finely adjusted by rotating it. After the adjustment is completed, the scanner 21 starts to work and acquires images of the printed matter. During the transmission of the printed matter, the drive motor 5 works continuously, causing the scanner 21 to move along the transmission direction of the printed matter and perform a comprehensive scan and detection of the printed matter. The image data acquired by the scanner 21 is transmitted to the image processing system in real time. The system analyzes and processes the image through a preset detection algorithm to detect whether there are quality problems such as color difference, ink spots, and misregistration in the printed matter.
