Description

Technical Field

[0001] This utility model relates to the field of printing quality inspection technology, and in particular to a high-speed quality inspection device for printed materials. Background Technology

[0002] Printed materials are widely used in packaging, labeling, books and periodicals, and security and anti-counterfeiting fields. With the popularization of high-speed production lines such as flexographic, gravure, web offset printing, and digital inkjet printing, production speeds often reach 150-600 m / min. Under high-speed conditions, defects such as missing prints, dirt, scratches, holes, broken edges, wrinkles, creases, ink splatter, pinholes, skipped lines, ink dragging, misregistration, smearing, color difference, and missing dots are prone to occur. If only manual sampling or visual inspection during machine stoppage is relied upon, it is difficult to achieve 100% online quality control across the entire frame and at all times, which poses the risk of missed inspections, misjudgments, and delayed scrapping, increasing material and energy costs.

[0003] The aforementioned existing technical solutions have the following drawbacks: limited exposure time leads to motion blur; traditional side-lighting / backlighting solutions are prone to hot spots and artifacts, resulting in missed detection of small defects; when the camera covers a wide area, the brightness and geometric distortion of the stitching area are inconsistent, which can easily create detection blind spots or repeated alarms. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed quality inspection device for printed materials to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-speed quality inspection device for printed materials includes a base, a column fixedly installed at the top left end of the base with its axis vertically aligned, and a conveyor plate fixedly installed at the top right end of the base; a vertical guide module fixedly installed on the front side of the column with its axis vertically aligned, used to control the vertical movement of the quality inspection module; left and right guide modules fixedly installed on the front side of the vertical guide module with their axes horizontally aligned, used to control the left and right movement of the quality inspection module; and a quality inspection module fixedly installed on the right side of the left and right guide modules with its axis vertically aligned, used to inspect the printed materials.

[0007] By adopting the above technical solution, this high-speed quality inspection device for printed materials achieves high-speed quality inspection through the collaborative work of multiple modules, matching the speed of the printing production line and avoiding production bottlenecks. This means that while ensuring inspection accuracy, it does not reduce the efficiency of the overall printing production, helping enterprises to further improve production efficiency and market competitiveness while improving product quality, and reducing cost waste and customer complaint risks caused by quality problems.

[0008] In a further embodiment, the vertical guide module includes a first housing, a first drive motor, a first guide rod, and a first base. The first housing is fixedly installed on the front side of the column, and the axis of the first housing is vertically arranged. The front end face of the first housing is in contact with the rear end face of the column. The first drive motor is fixedly installed on the top of the first housing, and the axis of the first drive motor is vertically arranged. The first guide rod is fixedly installed on the bottom of the first drive motor, and the axis of the first guide rod is collinear with the axis of the first drive motor. The first guide rod is slidably installed with the first base, and the axis of the first base is collinear with the axis of the first guide rod.

[0009] By adopting the above technical solution, the collinearity of the axis of the first base and the axis of the first guide rod ensures that the movement trajectory of the first base remains on a straight line in the vertical direction when sliding on the first guide rod, effectively avoiding lateral forces and additional torques caused by axis offset. This collinear design allows the driving force output by the first drive motor to be completely transmitted axially to the first base, reducing energy loss and improving transmission efficiency. Simultaneously, the collinearity of the axes ensures a uniform distribution of the fit clearance between the first base and the first guide rod, reducing frictional resistance and wear during sliding and extending the service life of the components. Furthermore, the collinear structure makes the overall stress state of the vertical guide module more stable, avoiding vibration and noise caused by eccentricity, ensuring smooth operation of the module during work, improving guiding accuracy and positioning accuracy, and thus guaranteeing the overall performance and reliability of the equipment.

[0010] In a further embodiment, the left and right guide module includes a second housing, a second drive motor, a second guide rod, and a second base. The second base is fixedly installed on the rear side of the first base, and the axis of the second base is arranged left and right. The front end face of the second base is in contact with the front end face of the first base. The second housing is slidably installed on the rear side of the second base, and the axis of the second housing is arranged left and right. The second base and the second guide rod are slidably installed, and the axis of the second guide rod is collinear with the axis of the second base. The left and right ends of the second guide rod are rotatably installed in the second housing. The left side of the second housing is fixedly installed with the second drive motor, and the right end of the second drive motor is rotatably installed with the second guide rod. The axis of the second drive motor is collinear with the axis of the second guide rod.

[0011] By adopting the above technical solution, the axis of the second drive motor and the axis of the second guide rod are collinear, ensuring that the driving torque output by the second drive motor can be directly and without deviation transmitted to the second guide rod, avoiding additional radial force or torque caused by misalignment of the axes. This collinear arrangement allows the second guide rod to only produce pure axial rotation under the drive of the second drive motor, thereby ensuring the smoothness and accuracy of the movement of the second housing when sliding along the second base, reducing mechanical wear caused by uneven force during transmission, extending the service life of the left and right guide modules, and improving the transmission efficiency and control precision of the entire module, ensuring that it can stably and reliably complete the left and right guide actions according to the preset trajectory during operation.

[0012] In a further embodiment, the quality inspection module includes a first rectangular block, a camera, and LED lights. The first rectangular block is fixedly installed on the right side of the second housing. The axis of the first rectangular block is vertically set. The camera is fixedly installed at the bottom of the first rectangular block. The axis of the camera is collinear with the axis of the first rectangular block. The bottom of the first rectangular block has integrally formed triangular protrusions symmetrically arranged front and back. LED lights are fixedly installed on the inclined surfaces of the triangular protrusions.

[0013] By adopting the above technical solution, from the perspective of lighting efficiency and energy consumption optimization, symmetrically arranged LED lights can specifically focus illumination on the camera's shooting area, avoiding meaningless light diffusion and improving lighting efficiency. Compared with traditional large-area lighting methods, this directional lighting can reduce the power consumption of LED lights while ensuring sufficient illumination brightness, thereby achieving energy-saving effects and meeting the requirements of modern industrial production for green energy conservation.

[0014] In a further embodiment, a first rectangular groove is provided on the top of the conveyor plate, the axis of the first rectangular groove is arranged front and back, a conveyor belt is rotatably installed in the first rectangular groove, and the bottom end face of the conveyor belt is in contact with the top end face of the first rectangular groove.

[0015] By adopting the above technical solution, the contact between the bottom surface of the conveyor belt and the top surface of the rectangular trough can reduce the vibration amplitude of the conveyor belt during operation. At the same time, the stable contact can also avoid abnormal noise caused by uneven collision or friction between the conveyor belt and the support surface, creating a relatively quiet working environment.

[0016] In a further embodiment, brackets are fixedly installed at each of the four corners of the base, and the axes of the brackets are all vertically aligned.

[0017] By adopting the above technical solution, the support frame lifts the base off the ground, preventing the base from direct contact with the ground and being corroded by ground moisture, dust, or corrosive substances, thus extending the service life of the base. At the same time, the gap at the bottom also facilitates operators to clean, inspect, or arrange and maintain related pipelines under the base, improving the convenience and maintainability of the equipment during use.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The vertical guide module can be used to adjust the vertical height of the quality inspection module;

[0020] 2. By setting up the left and right guide modules, the left and right directions of the quality inspection module can be adjusted;

[0021] 3. The quality inspection module can be used to inspect the quality of printed materials. Attached Figure Description
