Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box printing inspection technology, specifically a visual inspection device for corrugated cardboard box printing patterns. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading. Printing is a technology that mass-produces original artwork such as text, pictures, photographs, and anti-counterfeiting materials by transferring ink to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC through processes like plate making, inking, and pressing. Printing is the process of transferring approved printing plates onto the substrate using printing machinery and special inks. To understand the use of corrugated boxes, visual inspection devices for printed patterns are mainly used to monitor printing quality in real time, ensuring that patterns, text, and colors meet standards.

[0003] Current visual inspection devices for corrugated cardboard box printing patterns are prone to misalignment when transporting corrugated cardboard boxes, leading to errors in visual inspection and resulting in low inspection efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a visual inspection device for printed patterns on corrugated boxes, which solves the problem mentioned in the background art that the corrugated boxes being transported are prone to shifting during use, resulting in visual inspection errors and low inspection efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for printed patterns on corrugated cardboard boxes, comprising a visual registration machine, a first machine base, and a second machine base. Servo motors are mounted on the outer surfaces of both the first and second machine bases. A conveying device is mounted at the output end of each servo motor. A connecting seat is fixedly installed on the outer surface of the first machine base. A double-headed motor is mounted on the outer surface of the connecting seat. A lead screw is fixedly installed at the output end of the double-headed motor. A slide is slidably connected to the lead screw via the connecting seat. An auxiliary frame is fixedly installed on the outer surface of the slide. A drive motor is mounted on the outer surface of the auxiliary frame. An auxiliary conveying component is mounted at the output end of the drive motor.

[0006] Preferably, a bracket is provided on the outer surface of the No. 1 base, a cleaning fan is fixedly installed on the outer surface of the bracket, a guide is provided at the output end of the cleaning fan, and the cleaning fan is located on the upper part of the conveying device.

[0007] Preferably, the auxiliary conveying component is disposed on both sides of the conveying device, and both the auxiliary conveying component and the conveying device are composed of a conveying mechanism and a conveying track, with the auxiliary conveying component slidably connected to the outer surface of the conveying device.

[0008] Preferably, the first and second bases are located on opposite sides of the vision registration machine. The outer surface of the first base is equipped with a controller, which is electrically connected to the drive motor, the dual-head motor, and the servo motor.

[0009] Preferably, the visual registration machine is a Hawker visual registration machine, and the guide is in the shape of an inverted funnel.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This visual inspection device for printed patterns on corrugated boxes operates by controlling a dual-head motor. The two output ends of the dual-head motor drive two lead screws to operate synchronously, causing two slides to slide in opposite directions under the constraint of the connecting seat. This causes two auxiliary frames to move closer or further away to accommodate corrugated boxes of different specifications. The auxiliary conveyor works with the conveying device to transport the corrugated boxes toward the visual inspection machine, thereby reducing the deviation of the conveyed corrugated boxes and improving the inspection efficiency of corrugated boxes.

[0012] 2. This visual inspection device for printed patterns on corrugated cardboard boxes operates by controlling a cleaning fan. While the corrugated cardboard is being visually inspected under the drive of the auxiliary conveyor and the conveying device, the device cleans the outer surface of the corrugated cardboard box and blows away the dust on the outer surface of the corrugated cardboard box, thereby reducing the impact of external pollution on the visual inspection results of the corrugated cardboard box.

[0018] 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.

[0019] Example 1:

[0020] Please refer to Figures 1-4.

[0021] A visual inspection device for printed patterns on corrugated cardboard boxes includes a visual registration machine 1, a first machine base 2, and a second machine base 3. Servo motors 14 are mounted on the outer surfaces of both the first and second machine bases 2 and 3. A conveying device 15 is mounted at the output end of each servo motor 14. A connecting seat 4 is fixedly mounted on the outer surface of the first machine base 2. A double-headed motor 5 is mounted on the outer surface of the connecting seat 4. A lead screw 6 is fixedly mounted at the output end of the double-headed motor 5. A slide 7 is slidably connected to the lead screw 6 via the connecting seat 4. An auxiliary frame 8 is fixedly mounted on the outer surface of the slide 7. A drive motor 9 is mounted on the outer surface of the auxiliary frame 8. An auxiliary conveying component 10 is mounted at the output end of the drive motor 9.

[0022] Specifically, by controlling the operation of the dual-head motor 5, the two output ends of the dual-head motor 5 drive the two lead screws 6 to operate synchronously, causing the two carriages 7 to slide in opposite directions under the restriction of the connecting seat 4, and causing the two auxiliary frames 8 to move closer or further away to adapt to corrugated boxes of different specifications. The auxiliary conveyor 10, together with the conveying device 15, transports the corrugated boxes toward the vision registration machine 1, thereby reducing the deviation of the conveyed corrugated boxes and improving the detection efficiency of corrugated boxes.

[0023] In the embodiment: the auxiliary conveyor 10 is disposed on both sides of the conveying device 15, and both the auxiliary conveyor 10 and the conveying device 15 are composed of a conveying mechanism and a conveying track, and the auxiliary conveyor 10 is slidably connected to the outer surface of the conveying device 15.

[0024] Specifically, because the auxiliary conveyor 10 is located on both sides of the conveying device 15, and both the auxiliary conveyor 10 and the conveying device 15 are composed of a conveying mechanism and a conveyor belt, energy is transferred to the drive wheel through the transmission system. The drive wheel meshes with the transmission system through gears or chains, converting rotational motion into linear motion. The track plates are connected by track pins to form a chain structure, which wraps around the drive wheel, guide wheel, and load wheel to form a closed loop. The conveyor belt relies on the static friction between the object and the belt surface to transport materials. When the conveyor belt moves, the friction overcomes the inertia of the object, causing it to move synchronously with the belt. The auxiliary conveyor 10 slides on the outer surface of the conveying device 15. Continuous visual inspection is performed on corrugated cardboard boxes.

[0025] In the embodiment: the first base 2 and the second base 3 are arranged on both sides of the visual registration machine 1. The outer surface of the first base 2 is provided with a controller, which is electrically connected to the drive motor 9, the dual-head motor 5 and the servo motor 14.

[0026] Specifically, base 2 and base 3 are located on both sides of the vision registration machine 1. At the same time, a controller is set on the outer surface of base 2. The controller is electrically connected to drive motor 9, dual-head motor 5 and servo motor 14. The controller is an existing structure and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail to facilitate centralized control of the relevant structure.

[0027] Working principle: Servo motors 14 are installed on the outer surfaces of both base 1 (2) and base 2 (3). A transmission device 15 is installed at the output end of each servo motor 14. A connecting seat 4 is fixedly installed on the outer surface of base 1 (2), and a dual-head motor 5 is installed on the outer surface of the connecting seat 4. A lead screw 6 is fixedly installed at the output end of the dual-head motor 5, and the lead screw 6 is slidably connected to a slide 7 via the connecting seat 4. An auxiliary frame 8 is fixedly installed on the outer surface of the slide 7, and a drive motor 9 is installed on the outer surface of the auxiliary frame 8. An auxiliary transmission component 10 is installed at the output end of the drive motor 9 to control the dual-head motors. Motor 5 operates, driving the two output ends of the dual-head motor 5 to drive the two lead screws 6 to operate synchronously, driving the two slides 7 to slide in opposite directions under the restriction of the connecting seat 4, and driving the two auxiliary frames 8 to move closer or further away to adapt to corrugated boxes of different specifications. The auxiliary conveyor 10, in conjunction with the conveying device 15, transports the corrugated boxes toward the visual registration machine 1. Compared with related technologies, the visual inspection device for printed patterns on corrugated boxes provided by this utility model has the following beneficial effects: thereby reducing the deviation of the conveyed corrugated boxes and improving the inspection efficiency of corrugated boxes.

[0028] Example 2:

[0029] Please refer to Figures 1-4.

[0030] A bracket 11 is provided on the outer surface of the No. 1 base 2. A cleaning fan 12 is fixedly installed on the outer surface of the bracket 11. A guide 13 is provided at the output end of the cleaning fan 12. The cleaning fan 12 is located on the upper part of the conveying device 15.

[0031] Specifically, by controlling the operation of the cleaning fan 12, the corrugated cardboard undergoing visual inspection is fixedly conveyed under the drive of the auxiliary conveyor and the conveying device 15, while the outer surface is cleaned and the dust on the outer surface of the corrugated cardboard box is blown away, thereby reducing the impact of external pollution on the visual inspection results of the corrugated cardboard box.

[0032] In this embodiment: the visual registration machine 1 is a Hawk visual registration machine 1, and the guide 13 is in the shape of an inverted funnel.

[0033] Specifically, because the visual registration machine 1 uses the Hawk visual registration machine 1, a device used in the printing and packaging industry, the alignment accuracy of the printing plates is crucial to print quality during the printing process. The Hawk visual registration machine 1 utilizes advanced vision technology to achieve high-precision registration. It captures information such as markings on the printing plate using a high-definition camera, then analyzes this image data using specialized image processing algorithms to determine the accurate position of the printing plate. Afterward, the machine automatically adjusts the position of the printing plates based on the analysis results, ensuring precise alignment between the various color printing plates with errors controlled within a very small range. This helps improve the registration accuracy of printed materials, reducing problems such as pattern shifts and color deviations caused by misregistration, thereby improving print quality and production efficiency. The guide 13 is funnel-shaped, allowing for more precise airflow guidance.

[0034] Working principle: A bracket 11 is set on the outer surface of the No. 1 base 2, and a cleaning fan 12 is fixedly installed on the outer surface of the bracket 11. A guide 13 is set at the output end of the cleaning fan 12, and the cleaning fan 12 is set on the upper part of the conveying device 15. The cleaning fan 12 is controlled to operate, and while fixing and conveying the corrugated cardboard that is being visually inspected under the drive of the auxiliary conveying component and the conveying device 15, the outer surface is cleaned and the dust on the outer surface of the corrugated cardboard box is blown away. Compared with related technologies, the visual inspection device for printed patterns on corrugated cardboard boxes provided by this utility model has the following beneficial effects: thereby reducing the impact of external pollution on the visual inspection results of corrugated cardboard boxes.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
