Description

Technical Field

[0001] This utility model relates to the field of automatic detection and waste removal technology, and in particular to an automatic detection and waste removal device for printed materials. Background Technology

[0002] Printed materials are various products produced using printing technology. Printing is the process of reproducing text, images, or patterns by transferring ink and other pigments to the surface of various substrates such as paper, fabric, and plastic film. Using automatic detection and waste removal devices during the printing process serves two purposes: firstly, it ensures print quality by accurately identifying problems such as misregistration, uneven ink distribution, and missing text or patterns, all for quality control purposes; secondly, it improves production efficiency, as high-speed detection and waste removal can adapt to the speed of modern printing production lines, reducing human error and labor intensity. For example, in large newspaper printing plants, it ensures continuous and efficient production.

[0003] Waste discharge devices generally include mechanical waste discharge devices, start-up waste discharge devices, and electromagnetic waste discharge devices. Among them, mechanical waste discharge devices usually include a drive motor or cylinder, an actuator, and a control system. The motor is used to drive the actuator to execute waste discharge commands. The actuator usually consists of structures such as push plates and pressure plates to move and discharge waste. The control system is used to identify waste and control the actuator.

[0004] Existing mechanical waste removal devices typically stop the conveyor belt when waste is detected, and then process the waste into the collection box by pushing or pressing. This greatly reduces waste removal efficiency when processing a large amount of printed materials, leading to increased operating costs and reduced device practicality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic waste detection and removal device for printed materials, which aims to improve the problem that the existing technology cannot quickly and conveniently remove waste materials, thus increasing operating costs and reducing the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic waste detection and removal device for printed materials, comprising a worktable, a mounting frame fixedly connected to the upper surface of the worktable, a housing fixedly connected to the upper surface of the worktable, a connecting shaft fixedly connected inside the mounting frame, a roller rotatably connected to one side of the outer wall of the connecting shaft, a connecting rod rotatably connected to one side of the outer wall of the connecting shaft, a fixed shaft rotatably connected to one end of the connecting rod, a roller rotatably connected to one end of the fixed shaft, a fixed frame fixedly connected to the upper surface of the worktable, a lifting assembly for adjusting the height of the roller rotatably installed inside the fixed frame, a guide rod fixedly connected inside the fixed frame, a sliding connection between the fixed shaft and one side of the outer wall of the guide rod, and a blocking assembly for preventing printed materials from falling onto the upper surface of the worktable; the lifting assembly includes a lead screw, a collar rotatably connected to one side of the outer wall of the lead screw, a collar fixedly connected to one end of the fixed shaft, a motor fixedly connected to one side of the outer wall of the fixed frame, and the output end of the motor fixedly connected to one end of the lead screw.

[0007] Furthermore, the blocking assembly includes a baffle plate, one end of which is rotatably connected inside the worktable, and the upper surface of the baffle plate is in contact with the lower surface of the roller.

[0008] Furthermore, the upper surface of the workbench is rotatably connected to symmetrical guide plates, and both guide plates have grooves inside.

[0009] Furthermore, a connecting frame is fixedly connected to the upper surface of the workbench, and a plug rod is slidably connected inside the connecting frame.

[0010] Furthermore, one end of the insertion rod is slidably connected inside the groove, and a nut is threaded onto one side of the outer wall of the insertion rod.

[0011] Furthermore, a conveyor belt is fixedly connected inside the workbench, and a display screen is fixedly connected to the upper surface of the workbench.

[0012] Furthermore, a baffle plate is fixedly connected to the upper surface of the workbench, and a collection box is fixedly connected to one side of the outer wall of the workbench.

[0013] Furthermore, a mounting bracket two is fixedly connected to the upper surface of the workbench, and a connecting shaft two is fixedly connected inside the mounting bracket two. The roller one is rotatably connected to one side of the outer wall of the connecting shaft two.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, a pair of rollers are used to bond the printed material together, thereby guiding the printed material. A motor drives a lead screw to rotate, and under the action of a guide rod, a fixed shaft can move along the guide rod, thereby driving the second roller to move up and down to open or close the first baffle. This achieves the effect of moving the printed material to the lower part of the baffle, thus realizing the effect of quick and convenient automatic waste removal. This solves the problem in the prior art that it is not possible to remove waste quickly and conveniently, which leads to increased operating costs and reduced practicality of the device, thereby improving the practicality of the device.

[0016] 2. In this utility model, grooves are respectively opened in the two rotatable guide plates, and then a connecting frame is installed above the grooves. The position of the two guide plates is adjusted by the plug rod installed in the connecting frame and the groove. The plug rod is connected to the plug rod by a nut threaded on it and can make close contact with the connecting frame, thereby fixing the position of the guide plate. This achieves the effect of guiding different printed materials, solving the problem that the guide structure in the existing device is usually of fixed specifications. When the printed material is too large or too small, it cannot play a guiding role, which leads to the offset of the printed material and affects the waste discharge efficiency. This improves the practicality of the device. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 and Figure 2 and Figure 3 This utility model provides an embodiment of an automatic waste detection and discharge device for printed materials, including a workbench 1. A mounting frame 3 is fixedly connected to the upper surface of the workbench 1, and a housing 24 is also fixedly connected to the upper surface of the workbench 1. A connecting shaft 8 is fixedly connected inside the mounting frame 3, and a roller 7 is rotatably connected to one side of the outer wall of the connecting shaft 8. During the printing process, the roller 7 guides and transports the printed materials through its rotation, and simultaneously flattens and positions the surface of the printed materials to a certain extent. A connecting rod 4 is rotatably connected to one side of the outer wall of the connecting shaft 8, and a fixed shaft 11 is rotatably connected to one end of the connecting rod 4. The fixed shaft 11 is the mounting and support component for the second roller 10. It also adjusts its position in conjunction with the connecting rod 4 and the guide rod 13, thereby driving the second roller 10 to perform lifting and lowering actions. One end of the connecting rod 4 is rotatably connected to the fixed shaft 11, and the other end of the fixed shaft 11 is rotatably connected to the second roller 10. A fixed frame 5 is fixedly connected to the upper surface of the worktable 1. The fixed frame 5 provides the mounting position and support structure for the lifting assembly and the guide rod 13, ensuring that the lifting assembly can stably adjust the height of the second roller 10, while also ensuring that the position of the guide rod 13 is fixed. The fixed frame 5 contains a mechanism for adjusting... The roller 2 10 height adjustment assembly has a guide rod 13 fixedly connected inside the fixed frame 5, and a fixed shaft 11 slidably connected to one side of the outer wall of the guide rod 13. A blocking assembly to prevent printed materials from falling is installed on the upper surface of the worktable 1. The lifting assembly includes a lead screw 15, which transmits the power of the motor 6 to the collar 14 through its rotation, thereby adjusting the height of the roller 2 10. One side of the lead screw 15 is rotatably connected to the inside of the fixed frame 5, and the collar 14 is threadedly connected to one side of the lead screw 15. The collar 14 connects the lead screw 15 and the fixed shaft 11, controlling the rotational movement of the lead screw 15. The motion is converted into linear motion of the fixed shaft 11, thereby driving the roller 10 to rise and fall. One side of the outer wall of the collar 14 is fixedly connected to one end of the fixed shaft 11. One side of the outer wall of the fixed frame 5 is fixedly connected to the motor 6. The output end of the motor 6 is fixedly connected to one end of the lead screw 15. The blocking assembly includes a baffle 19. One end of the baffle 19 is rotatably connected to the inside of the worktable 1. The upper surface of the baffle 19 is in contact with the lower surface of the roller 10. When the roller 10 rises, the baffle 19 closes to prevent the printed matter from falling. When the roller 10 falls, the baffle 19 is pressed open, allowing waste printed matter to enter the baffle 19.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The upper surface of the worktable 1 is rotatably connected to symmetrical guide plates 25. The guide plates 25 guide the printed materials, ensuring they move accurately in a predetermined direction on the conveyor belt and preventing deviation. Both guide plates 25 have internal grooves 17, which provide sliding tracks for the insert rods 18, thus allowing adjustment of the guide plate 25's position. A connecting frame 16 is fixedly connected to the upper surface of the worktable 1. The insert rods 18 are slidably connected inside the connecting frame 16. By changing the position of the insert rods 18 within the grooves 17, the angle and spacing of the guide plates 25 can be altered, thereby meeting the guiding needs of printed materials of different widths and shapes. The insertion rod 18 is slidably connected to the inside of the slide groove 17. A nut 12 is threadedly connected to one side of the outer wall of the insertion rod 18. The nut 12 is used to fix the position of the insertion rod 18. A conveyor belt 2 is fixedly connected inside the worktable 1. A display screen 23 is fixedly connected to the upper surface of the worktable 1. A baffle 22 is fixedly connected to the upper surface of the worktable 1. The baffle 22 serves to prevent printed materials from accidentally falling into the collection box 9. A collection box 9 is fixedly connected to one side of the outer wall of the worktable 1. A mounting bracket 20 is fixedly connected to the upper surface of the worktable 1. A connecting shaft 21 is fixedly connected inside the mounting bracket 20. A roller 7 is rotatably connected to one side of the outer wall of the connecting shaft 21.

[0026] Working principle: When using the device, the printed material is first placed on the conveyor belt 2 inside the workbench 1 for conveying. At this time, the printed material first passes through the two guide plates 25. Rotating the nut 12 makes it disengage from the upper surface of the connecting frame 16. Then, the position of the two guide plates 25 can be adjusted by sliding the rod 18. After adjustment, rotating the nut 12 in the opposite direction makes it tightly adhere to the connecting frame 16 to complete the fixation. Next, the roller 7 applies the printed material to the surface and plays a guiding role. When waste material is detected, the motor 6 is started. The motor 6 drives the lead screw 15 to rotate. The lead screw 15 is threadedly connected to the collar 14. The collar 14 is fixed to one end of the fixed shaft 11. Under the guidance of the guide rod 13, the fixed shaft 11 can move along the guide rod 13, thereby driving the roller 2 10 to move up and down. When the roller 2 10 rises, the baffle 19 will close to prevent the printed matter from falling and allow the printed matter to pass smoothly. When the roller 2 10 falls, the baffle 19 will be pressed open, allowing waste printed matter to enter the baffle 19 and then reach the collection box 9. Then, after the valid printed matter is guided by multiple rollers 1 7, it reaches the baffle 2 22 for collection.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
