Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate roller detection, and more specifically to a device for detecting leakage points of plate rollers with multiple mesh shapes. Background Art
[0002] A multi-mesh engraved roller is a roller with a variety of different mesh shapes engraved on the surface. It is commonly used in printing, coating and other industries. In the coating process, it can be used to accurately control the coating amount and coating uniformity of the coating liquid, such as in paper coating, film coating, etc., so that the coated products have good performance and quality.
[0003] The current mesh-and-engraving roller printing process presents significant challenges. For one thing, the edges of printed patterns exhibit severe jaggedness and frequent missed dots. This not only significantly impacts the quality and aesthetics of the printed pattern, but also significantly reduces the product's market competitiveness.
[0004] On the other hand, existing quality inspection methods have significant flaws. After printing is complete, print quality is typically assessed by cutting off one end of the printed product and removing it for visual inspection. This method not only places a high workload on inspectors, but also easily leads to fatigue from repetitive work over time. Furthermore, due to the limitations of the human eye, minor details can easily be overlooked, making it difficult to accurately identify all possible leaks and, consequently, preventing timely and comprehensive control of print quality.

[0005] To overcome the shortcomings of the prior art, the present invention provides a device for detecting missing points on a multi-grid engraving roller. This device can capture and inspect different positions of the printing press roller and the printing plate after printing, achieving comprehensive missing point detection. It also sprays and cleans industrial cameras, preventing dust and debris from accumulating after prolonged use, ensuring optimal photography.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0007] A device for detecting leakage points of multiple mesh-shaped engraved rollers comprises a frame, a printing press and a detection frame, wherein the printing press and the detection frame are both arranged on the frame, and the printing press and the detection frame are both arranged horizontally.

[0009] A connecting frame is provided on the processing box, and the processing box is arranged on the frame through the connecting frame.
[0010] The top of the air intake pipe is connected to an air intake box, which is a top-opening structure. A heating wire is arranged in the air intake box, and an air intake fan is arranged in the air intake pipe.
[0011] A reinforcement frame is provided between the processing box and the air intake box.
[0012] The water outlet pipe is arranged below the detection frame in the processing box, a nozzle is arranged on the upper surface of the water outlet pipe, and the water outlet pipe is connected to the water inlet pipe.
[0013] A waste receiving pipe is provided at the bottom of the processing box. The top of the waste receiving pipe is an open structure and is communicated with the processing box. A waste discharge pipe is provided at the bottom of the waste receiving pipe.

[0022] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0024] like Figures 1 to 5 As shown, a device for detecting leakage points of multiple mesh-shaped engraving rollers includes a frame 1, a printing press 102 and a detection frame 2. The printing press 102 and the detection frame 2 are both arranged on the frame 1, and the printing press 102 and the detection frame 2 are both arranged horizontally. The detection frame 2 is arranged on the front side of the printing press 102, and a guide block 201 is slidingly provided on the detection frame 2. An industrial camera 202 is provided at the bottom of the guide block 201, and a processing box 4 is provided at one end of the detection frame 2. An air inlet pipe 408 is provided on the top of the processing box 4, and a water outlet pipe 410 is provided in the processing box 4.
[0025] The inner hole of the guide block 201 is adapted to the outer shape of the detection frame 2 and can slide smoothly along the detection frame 2. The guide block 201 is mounted on the screw rod 302 through a thread. When the screw rod 302 rotates under the drive of the drive motor 3, the guide block 201 will move linearly along the axial direction of the screw rod 302 due to the action of the thread. An industrial camera 202 is mounted on the bottom end face of the guide block 201. The industrial camera 202 has high resolution and fast shooting performance, and can clearly shoot the surface conditions of various mesh-shaped engraved rollers. As the guide block 201 moves, the industrial camera 202 can shoot and detect different positions of the plate roller, thereby achieving comprehensive leakage point detection. The industrial camera 202 can cooperate with the program preset in the control panel 101 to analyze the shooting picture, and display the shooting analysis data through the display screen installed on the control panel 101.
[0026] Preferably, a bracket 203 is provided on the side of the detection frame 2 away from the processing box 4, and the detection frame 2 is set on the frame 1 through the bracket 203. A screw rod 302 is rotatably arranged between the bracket 203 and the processing box 4. The screw rod 302 passes through the guide block 201 and is threadedly connected to the guide block 201. A driving motor 3 connected to the screw rod 302 is provided on the bracket 203, and the driving motor 3 is fixed to the bracket 203 through the mounting bracket 301.
[0027] The bolted connection allows for easy installation and removal of bracket 203 from frame 1. During assembly, personnel can quickly secure bracket 203 to the frame and flexibly adjust its position on frame 1 based on actual needs, ensuring the installation angle and position of detection frame 2 meet detection requirements. When the device requires maintenance or transport, bracket 203 can also be easily removed from frame 1 for ease of operation.
[0028] Preferably, a connecting bracket 406 is provided on the processing box 4, and the processing box 4 is mounted on the frame 1 via the connecting bracket 406. The connecting bracket 406 stabilizes the processing box. The connecting bracket 406 is connected to the frame 1 via bolts, allowing the processing box 4 to be stably installed next to the frame 1 and work in conjunction with the detection frame 2 and other components.
[0029] Preferably, the top of the air intake duct 408 is connected to an air intake box 402. The air intake box 402 is open at the top and contains a heating wire 401. An air intake fan is also installed within the air intake duct 408. The air intake fan draws ambient air through the air intake box into the air intake duct 408 and transports it to the processing box 4. Inside the air intake box 402, the heating wire 401 generates heat when energized, heating the air passing through it. The heated air then enters the processing box 4 through the air intake duct, heating and drying the cleaned industrial camera 202 inside the processing box 4 to prevent water from adhering and affecting subsequent filming.
[0030] Preferably, a reinforcement frame 407 is provided between the processing box 4 and the air inlet box 402.
[0031] Reinforcement frame 407 enhances the stability of the connection between processing box 4 and air intake box 402. During operation, processing box 4 and air intake box 402 may be subject to various external forces, such as vibration and airflow impact. Bolted to them, reinforcement frame 407 effectively disperses these external forces, preventing damage to the connection between processing box 4 and air intake box 402 due to excessive force. Furthermore, reinforcement frame 407 protects processing box 4 and air intake box 402 during installation and transportation, preventing them from deformation or damage due to collisions, thereby improving the reliability and stability of the entire device.
[0032] Preferably, the water outlet pipe 410 is arranged below the detection frame 2 in the processing box 4 , a nozzle 409 is provided on the upper surface of the water outlet pipe 410 , and the water outlet pipe 410 is connected to the water inlet pipe 403 .
[0033] The water inlet pipe 403 provides a stable source of liquid for the water outlet pipe 410. By embedding and securing the water inlet pipe 403 in the side end face of the water outlet pipe 410, liquid communication is achieved. The water inlet pipe 403 can be connected to a pump or other mechanism to pump clean water. During this pumping process, the water is sprayed through the nozzle 409 on the water outlet pipe 410 onto the industrial camera 22 that has entered the processing box 4, preventing dust and debris from accumulating on the industrial camera 22 after prolonged use.
[0034] Preferably, a waste pipe 405 is provided at the bottom of the processing box 4 , the top of the waste pipe 405 is an open structure, connected to the processing box 4 , and a waste discharge pipe 404 is provided at the bottom of the waste pipe 405 .
[0035] Waste connection pipe 405 and waste discharge pipe 404 together constitute the waste liquid discharge system within the treatment tank. During the inspection process, used liquid in the treatment tank, such as water with impurities after the industrial camera, can be collected through waste connection pipe 405. The bottom end surface of waste connection pipe 405 is embedded and connected to waste discharge pipe 404, allowing the waste liquid to be smoothly discharged through waste discharge pipe 404 to a designated waste liquid collection device. This design can effectively clean the waste liquid in the treatment tank, keeping the interior of the treatment tank clean, and preventing waste liquid accumulation from affecting the normal operation of the device. It is also beneficial to the environment and prevents the indiscriminate discharge of waste liquid from polluting the environment.
[0036] Preferably, a control panel 101 is provided on the rack 1 , and the control panel 101 is electrically connected to the industrial camera 202 .
[0037] During use, the operator starts the device through the control panel 101 on the side of the frame 1, and places the various mesh-shaped engraved rollers to be tested at appropriate positions on the printing press 102. The drive motor 3 on the detection frame 2 is started, and its output shaft drives the screw 302 to rotate. The guide block 201 is installed on the screw 302 through a thread because its inner hole is adapted to the outer shape of the detection frame 2. When the screw 302 rotates, the guide block 201 will move linearly along the axial direction of the screw 302. The industrial camera 202 installed on the bottom end face of the guide block 201 takes pictures of the plate roller and the printed product at different positions as the guide block 201 moves. Since the industrial camera 202 has high resolution and fast shooting performance, it can clearly capture the surface condition of the plate roller. The industrial camera 202 cooperates with the preset program in the control panel 101 to analyze the shooting picture, and displays the shooting analysis data through the display screen on the control panel 101, thereby realizing comprehensive leakage detection. The water inlet pipe 403 is connected to a water pump or other mechanism to extract clean water. Because the water inlet pipe 403 is embedded and fixed on the side end face of the water outlet pipe 410 and is liquid-connected, the water is sprayed and cleaned by the nozzle 409 on the water outlet pipe 410 on the industrial camera 202 moving into the processing box 4, preventing the industrial camera 202 from adhering to dust and debris after long-term use. The air intake fan draws external air into the air intake pipe 408 through the air intake box 402 and transports it to the processing box 4. The heating wire 401 in the air intake box 402 is energized to generate heat, heating the passing air. The heated air enters the processing box 4 through the air intake pipe 408, heating and drying the cleaned industrial camera 202, preventing the adhering water from affecting subsequent shooting. During the inspection process, the used water with impurities in the processing box 4 is collected through the waste pipe 405. The bottom end surface of the waste pipe 405 is embedded and connected with the waste pipe 404, so that the waste liquid can be discharged smoothly through the waste pipe 404 to the designated waste liquid collection device, keeping the inside of the processing box 4 clean, avoiding the accumulation of waste liquid affecting the normal operation of the device, and preventing the waste liquid from being discharged at will to pollute the environment.
[0038] The above only describes in detail the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
