Description

Technical Field

[0001] This utility model relates to the field of tinplate printing technology, specifically an automatic rejection device for tinplate printing. Background Technology

[0002] In the tinplate printing and can-making industry, tinplates need to go through multiple processes to become finished products. With continuous technological innovation, online quality inspection systems are now widely used to control the printing quality of tinplates. The most widely used system is a high-speed camera in a video inspection device, which takes pictures of the passing tinplates and compares them with sample images to determine whether the printing is qualified. For unqualified products, the usual method is to stop the machine and reject them. This method greatly affects the overall production efficiency. Some technicians have proposed to install push rods on the side of the conveyor and connect them to the video inspection device to calculate the conveying speed and time. The automatic push rods would then remove the problematic tinplates from the conveying sequence. However, the side push requires extremely high precision and is prone to failure. At the same time, it requires personnel to monitor the rejection structure for a long time and manually remove the rejected tinplates, which is labor-intensive.

[0003] Therefore, designing a device that reduces labor costs, improves the efficiency of removing iron plates, and increases production efficiency is the problem that the inventors want to solve. Utility Model Content

[0005] The technical solution adopted by this utility model device is as follows: an automatic rejection device for iron plate printing, which is set inside the equipment frame. A belt conveyor is set inside the equipment frame, and a camera inspection device is set at the end of the equipment frame. The belt conveyor includes cross-arranged conveyor belts. Ear plates are set at opposite edges of the equipment frame. A first drive shaft is rotatably set inside the ear plate. A first motor is connected to the end of the first drive shaft. A rejection roller is fixedly connected to the circumferential surface of the first drive shaft. A side bracket is set on the side of the ear plate. A receiving plate is bolted to the end of the side bracket. A second drive shaft is rotatably set inside the equipment frame. A second motor is connected to the end of the second drive shaft. A rectangular connecting block is fixedly set outside the second drive shaft by a set screw. A rejection rod is connected to the end of the rectangular connecting block.

[0006] Furthermore, the receiving plate includes a receiving section and a sliding section. Two opposite mounting grooves are formed on the end face of the receiving section.

[0009] Furthermore, the driven roller is located near the connection between the receiving section and the sliding section.

[0010] Furthermore, the end of the rejection rod is provided with an arc structure, and the height of the end of the rejection rod is lower than the height of the belt of the belt conveyor under normal conditions.

[0011] Furthermore, the end of the receiving plate is close to the rejection roller, and the height of the upper edge of the right end of the receiving plate is lower than the height of the upper end of the rejection roller.

[0012] The beneficial effects of this utility model device are:

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] Example 1: See Figure 1 This is a structural view of the utility model. Figure 1A partial enlarged view at point A and a structural view of the receiving plate 12 are shown. An automatic rejection device for tinplate printing is installed inside a machine frame 1. A belt conveyor is installed inside the machine frame 1, and a camera inspection device 3 is installed at the end of the machine frame 1. The belt conveyor includes cross-laid conveyor belts for easy transfer of tinplates. Gaps exist between the conveyor belts. Oppositely arranged ear plates 4 are provided at the edge of the machine frame 1. A first drive shaft 6 is rotatably mounted inside the ear plate 4, and a first motor 5 is connected to the end of the first drive shaft 6. A rejection roller 7 is fixedly connected to the circumference of the first drive shaft 6. The first motor 5 drives the first drive shaft 6, thereby driving the rejection roller 7 fixedly mounted to the first drive shaft 6 to rotate. A side bracket 20 is provided on the side of the ear plate 4, and a receiving plate 12 is bolted to the end of the side bracket 20. A second drive shaft 11 is rotatably mounted inside the machine frame 1, and the end of the second drive shaft 11 is connected to... A second motor 10 and a second drive shaft 11 are provided with a rectangular connecting block 9 fixed to the outside of the shaft by a set screw. The end of the rectangular connecting block 9 is connected to a rejection rod 8. The second drive shaft 11 passes through the conveyor belt. The rejection rod 8 is set in the gap between the conveyor belts. In the axial direction, rejection rods 8 are set on the inner side of the gap between adjacent conveyor belts. When the iron plate passes through the camera inspection device 3, if a defect is detected, the signal of the camera inspection device 3 is transmitted to the controller set on the side of the camera inspection device 3. The controller then calculates the time and distance and controls the second motor 10 to rotate the rejection rod 8, lifting one end of the defective iron plate. Because the other end of the iron plate is still in contact with the conveyor belt, it will be continuously conveyed. At the same time, the other end moves forward because it is lifted, and will contact the rejection roller 7 and finally be conveyed into the receiving tray 12 by the rejection roller 7 driven by the first motor 5. The edge of the receiving tray 12 is provided with a limit structure.

[0020] The receiving plate 12 includes a receiving section 13 and a sliding section 14. Two opposing mounting grooves are formed on the end face of the receiving section 13. A connecting bracket 15 is installed inside the mounting groove. A driven roller 16 is rotatably mounted inside the connecting bracket 15 via a pin. A driving roller 17 is also installed inside the connecting bracket 15. The two driving rollers 17 are connected by a transmission rod 19, and the driving roller 17 is rotatably mounted to the connecting bracket 15 via the transmission rod 19. The driving roller 17 and the driven roller 16 are driven by friction. A third motor 18 is connected to the end of the transmission rod 19. The upper end of the driven roller 16 is located inside the receiving section 13 of the receiving plate 12. The sliding section 14... The lower end is set on the side of the equipment frame 1. The lower end of the sliding section 14 is equipped with a collection box for receiving. The driven roller 16 is set near the connection between the receiving section 13 and the sliding section 14. The third motor 18 is also controlled by the controller. When the controller receives the signal from the camera inspection device 3, it simultaneously sends a signal to the third motor 18 to control the rotation of the third motor 18. When the unqualified iron plate falls into the receiving tray 12, the third motor 18 drives the driving roller 17 and the driven roller 16 to rotate. Through the friction between the driven roller 16 and the iron plate, the unqualified iron plate slides along the sliding section 14 out of the belt conveyor 2 and the equipment frame 1 and into the collection box.

[0021] In order not to hinder the normal conveying of the iron plate, the end of the ejector rod 8 is provided with an arc structure, and the height of the end of the ejector rod 8 is lower than the belt height of the belt conveyor 2 under normal conditions.

[0022] In order to allow the iron plate to pass through the rejection roller 7 and enter the receiving plate 12 more smoothly, the end of the receiving plate 12 is close to the rejection roller 7 and the upper edge of the right end of the receiving plate 12 is lower than the upper end of the rejection roller 7.

[0023] This invention uses a motor-driven push rod to quickly push out the problematic iron plate, which is then conveyed to the receiving tray 12 via the rejection roller 7. The receiving tray 12 has a built-in transverse conveying structure that can transport the rejected iron plate away from the belt conveyor 2 and into the container for storage. This process does not require manual supervision of the workstation, saving labor costs and eliminating the need for machine downtime. It achieves the functions of reducing labor costs, improving the efficiency of iron plate rejection, and increasing production efficiency.
