Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] like Figures 1 to 3 As shown, a printed material rejection conveying device includes a frame 1, on which a front suction box mechanism 2 for conveying good and bad products is provided. At the end of the front suction box mechanism 2 are a lower suction box mechanism 3 and a rear suction box mechanism 4. The front suction box mechanism 2 is equipped with a rejection mechanism that can change the movement path of bad products. After the printed materials pass inspection, they enter the front suction box mechanism 2 for conveying. Bad products reach the rejection mechanism, which then sends them to the lower suction box mechanism 3. Good products continue to be conveyed by the front suction box mechanism 2 to the rear suction box mechanism 4.
[0029] The front suction box mechanism 2, the lower suction box mechanism 3, and the rear suction box mechanism 4 are all composed of conventional components such as suction belts and suction boxes, and their structures will not be described in detail here. The waste removal mechanism is controlled by a conventional control device, which is not directly related to the mechanical mechanism of this application, and will not be described in detail here.
[0030] The rejection mechanism includes a flap assembly 5 and / or an air blowing assembly 6. The flap assembly 5 presses down the defective product, causing it to enter the lower suction box mechanism 3, while the air blowing assembly 6 blows the defective product into the lower suction box mechanism 3. The air blowing assembly 6 and the flap assembly 5 are located at the end of the front suction box mechanism 2. The air blowing assembly 6 is located above the flap assembly 5, and the front end of the lower suction box mechanism 3 is located below the flap assembly 5. Defective products sent from the front suction box mechanism 2 are fed into the lower suction box mechanism 3 by the flap assembly 5 and the air blowing assembly 6. Since the flap assembly 5 and the air blowing assembly 6 can work simultaneously, the rejection speed can be improved, ensuring that defective products smoothly transition from the front suction box mechanism 2 to the lower suction box mechanism 3.
[0031] like Figure 4 As shown, the flip-plate assembly 5 includes a cylinder 51 mounted on the frame 1, a swing arm 52 connected to the cylinder 51, a rotating shaft 53 connected to the swing arm 52, and multiple flip plates 54 mounted on the rotating shaft 53. The flip plates 54 rotate and press down on defective products, causing them to enter the lower suction box mechanism 3. The flip plates 54 are evenly spaced along the width direction of the front suction box mechanism 2. This even arrangement of flip plates 54 ensures uniform pressure on the defective products, guiding them smoothly into the lower suction box mechanism 3. When the defective product moves to the bottom of the flip-plate assembly 5, the cylinder 51 drives the swing arm 52 and the rotating shaft 53 to rotate. The rotating shaft 53 causes the flip plates 54 to press down, contacting the defective product. The flip plates 54 change the movement path of the defective product, which was originally moving forward, and move it towards the lower suction box mechanism 3. The defective product is then conveyed by the lower suction box mechanism 3 into the paper receiving section.
[0032] like Figure 5 As shown, the air blowing assembly 6 includes a bracket 61 mounted on the frame 1, with multiple air blowing pipes 62 spaced apart on the bracket. The air blowing pipes press the defective products into the lower suction box mechanism 3. The air blowing pipes are evenly spaced along the width of the front suction box mechanism 2 and are arranged vertically. The air blowing pipes are connected to an air distribution block via pipelines, and the air distribution block has a solenoid valve to control the airflow. The air blowing pipes blow vertically downwards, and the airflow acts evenly on the surface of the defective products. Under the action of air pressure, the defective products are pressed down and move downwards into the lower suction box mechanism 3. The uniform and stable airflow ensures the smooth movement of the defective products.
[0033] The working principle of this utility model's printed matter rejection conveying device is as follows: After the printed matter is inspected, it is divided into good products and bad products. Both good and bad products are sent into the front suction box mechanism 2. After the bad products are transported to the end of the front suction box mechanism 2, the flip plate assembly 5 and the air blowing assembly 6 work to send the bad products into the lower suction box mechanism 3. When the good products pass through, the flip plate assembly 5 and the air blowing assembly 6 do not work, and the good products directly enter the rear suction box mechanism 4, thereby completing the rejection work.
[0034] In summary, the present invention provides a printing reject conveying device that uses a suction box mechanism to convey products and combines a flip plate assembly and an air blowing assembly for rejecting rejects. It is applicable to various types of products and significantly improves the rejecting speed.
[0035] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
