Description
Technical Field
[0001] This application relates to the technical field of plate feeders, and in particular to a material anti-drop device for plate feeders. Background Technology
[0002] In practical applications of plate feeders, materials tend to scatter from both sides during the conveying process, which not only wastes raw materials but also pollutes the working environment and increases cleaning costs. Traditional anti-drop devices mostly use fixed baffle structures, which cannot adapt to the conveying needs of materials with different particle sizes, leading to problems such as large materials getting stuck or small materials leaking. Although there are adjustable baffle designs in existing technologies, they generally have disadvantages such as complex structure, inconvenient adjustment, and high energy consumption. Moreover, most of them require an additional power source to drive the baffle adjustment, which increases equipment costs and maintenance difficulty. In addition, the slippage of the conveyor belt and the vibration and impact of the transmission system also affect the stability and service life of the equipment. Therefore, there is an urgent need to develop a material anti-drop device for plate feeders. Summary of the Invention

[0015] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0016] See Figure 1-4 A material anti-drop device for a plate feeder includes: a feeding device 1, with a first baffle 2 fixedly connected to both the front and rear sides of the feeding device 1; a first support plate 3 fixedly connected to the outer surface of the first baffle 2; a first rotating rod 8 rotatably connected to the inner wall of the first support plate 3; a synchronous wheel 4 fixedly connected to the top of the first rotating rod 8; a synchronous belt 5 sleeved on the surface of the synchronous wheel 4; the synchronous belt 5 adopts a double-layer polyurethane-coated steel wire core structure; the surface of the synchronous belt 5 is provided with anti-slip ridges, which are used to improve the meshing stability with the synchronous wheel 4; a second support plate 6 fixedly connected to the back surface of the first baffle 2 on the rear side; a rotating motor 7 fixedly connected to the bottom of the second support plate 6; the output end of the rotating motor 7 is fixedly connected to the bottom of the first rotating rod 8 on the rear side through a coupling; the coupling has a built-in buffer rubber pad, which is used to reduce transmission impact. When the feeder starts, the rotating motor 7 drives the first rotating rod 8 to rotate via the coupling, synchronously driving the synchronous pulley 4 and the synchronous belt 5 to operate, thus achieving stable material conveying. The synchronous belt 5 adopts a double-layer polyurethane-coated steel wire core structure, which combines flexibility and high strength. The anti-slip texture on the surface effectively enhances the meshing stability with the synchronous pulley 4 and prevents slippage. At the same time, the first bevel gear 9 on the first rotating rod 8 drives the second bevel gear 15 to rotate, causing the threaded rod 16 to rotate and pushing the moving plate 14 to slide along the slide plate 19. The moving plate 14 drives the rubber push plates 13 on both sides to move. The push plates 13 are tightly attached to the surface by the anti-slip texture. The second baffle 10 is closed, and appropriate lateral pressure is applied according to the particle size of the material. The second baffle 10 slides within the arc-shaped limiting frame 11 to form an adjustable inverted V-shaped material guide channel, which can accommodate the passage of large pieces of material and prevent small materials from scattering. The rubber material of the push plate 13 has a buffering effect, which can reduce the wear of the baffle caused by material impact. The detachable wear-resistant strip at the bottom of the second baffle 10 further extends its service life. The entire adjustment process does not require additional power input. The synchronous control of conveying and anti-drop can be achieved by the single drive of the rotating motor 7, which improves the energy efficiency ratio and automation level of the equipment.
[0017] Arc-shaped limiting frames 11 are fixedly connected to both the left and right sides of the first baffle 2. The arc-shaped limiting frames 11 on the front and rear sides are symmetrically distributed. A first bevel gear 9 is fixedly connected to the surface of the first rotating rod 8. A threaded rod 16 is rotatably connected to the inner wall of the first baffle 2. A limiting plate 17 is fixedly connected to the inner end of the threaded rod 16. A second bevel gear 15 is fixedly connected to the outer end of the threaded rod 16. The first bevel gear 9 and the second bevel gear 15 mesh with each other. A movable plate 14 is threadedly connected to the surface of the threaded rod 16. A limiting groove 18 is opened through the front side of the movable plate 14. The groove wall of the limiting groove 18 slides. A sliding plate 19 is connected, and the outer surface of the sliding plate 19 is fixedly connected to the inner surface of the first baffle 2. Push plates 13 are fixedly connected to both sides of the inner surface of the movable plate 14. The push plates 13 are made of rubber, and the inner surface of the push plates 13 is provided with anti-slip texture. The inner wall of the arc-shaped limiting frame 11 is slidably connected to the second rotating rod 12. The surface of the second rotating rod 12 is fixedly connected to the second baffle 10. The bottom of the second baffle 10 is provided with a detachable wear-resistant strip. There are two second baffles 10, which are symmetrically distributed on the left and right and are in an inverted V-shape. During material conveying, if a mixture of materials with different particle sizes is encountered, the pusher plate 13 moves outward or inward under the drive of the moving plate 14, dynamically adjusting the pushing force on the second baffle 10 to form the optimal guiding angle between the two baffles. When conveying large particles, the pusher plate 13 moves outward, reducing the pressure on the second baffle 10 and increasing the baffle opening to ensure smooth material passage. When conveying fine materials, the pusher plate 13 moves inward, increasing the squeezing force on the second baffle 10 and decreasing the baffle opening to effectively prevent material from scattering from both sides. The arc-shaped limiting frame 11 not only restricts the second baffle 10... The movement range is also enhanced by the smooth swing of the baffles guided by its arc structure, avoiding jamming. The inverted V-shaped arrangement of the second baffle 10 and the synergistic effect of the push plate 13 keep the material in a concentrated state during the conveying process, reducing dust and waste. In addition, the built-in buffer rubber pad of the coupling can absorb the vibration and impact of the rotating motor 7, reducing transmission noise. The steel wire core structure of the synchronous belt 5 ensures that it is not easily deformed or broken during long-term high-load operation. The device achieves adaptive adjustment through mechanical linkage, eliminating the need for a complex control system, which reduces manufacturing costs and improves reliability and maintenance convenience.
[0018] In this application, a rotating motor 7 drives a first rotating rod 8 to synchronously drive a synchronous belt 5 to convey materials. Simultaneously, the meshing transmission of a first bevel gear 9 and a second bevel gear 15 drives a threaded rod 16 to rotate, causing a moving plate 14 to drive a rubber push plate 13 to adjust the opening and closing angle of a second baffle 10. The device uses a synchronous belt 5 with a double-layer polyurethane-coated steel wire core structure to ensure conveying stability. The second baffle 10, arranged in an inverted V-shape, and the push plate 13 work together to achieve adaptive adjustment, ensuring smooth passage of large particles while effectively preventing the scattering of fine materials. An arc-shaped limit frame 11 guides the smooth swing of the second baffle 10. The coupling has a built-in buffer rubber pad to reduce transmission impact, and a detachable wear-resistant strip extends service life. The entire system achieves synchronous control of conveying and anti-drop through a single power source, and has the advantages of simple structure, flexible adjustment, reliable operation, and convenient maintenance, significantly improving the energy efficiency ratio and automation level of the feeder.
[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
