Description
A vibrating screen device for preventing clogging at the discharge port of a granulator Technical Field
[0001] This utility model relates to the field of granulator technology, and in particular to a granulator discharge port anti-clogging vibrating screen device. Background Technology
[0002] In industrial production fields such as chemicals, plastics, and food, granulators are key equipment for processing materials into granular products, and the smooth operation of their discharge port directly affects production efficiency and product quality. To ensure smooth discharge of granules and effective screening, the development of an anti-clogging vibrating screen device for the granulator discharge port has significant practical application value. This device aims to solve the clogging problem during the discharge process and improve screening efficiency.
[0003] In existing technologies, the structure of the discharge port of a granulator is usually relatively fixed, generally connected to screening equipment via a simple pipe. Its technical principle mainly relies on the gravity of the granules to be discharged from the discharge port, and then screened by a fixed screen. Under this mechanical structure and technical principle, the opening size of the discharge port is difficult to adjust flexibly according to actual production needs, and the screening process mainly depends on the natural fall and accumulation of the granules.
[0004] However, since the opening size of the discharge port of the existing granulator is difficult to control precisely, when the properties of the granules change during the production process, the granules are easily accumulated in the discharge pipe, which can cause blockage of the discharge port. This not only affects the continuity of production, but also requires frequent shutdowns for cleaning, increasing production costs and labor intensity. The design of the adjustment component in this utility model solves this problem. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a vibrating screen device for preventing blockage at the discharge port of a granulator. It aims to improve the problem that the opening size of the discharge port of the existing granulator is difficult to control precisely. During the production process, when the properties of the granules change, the granules can easily accumulate in the discharge pipe, thus causing blockage at the discharge port.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a vibrating screen device for preventing blockage at the discharge port of a granulator, comprising a support base, a discharge pipe fixedly connected to the inner wall of the support base, a fixing plate one fixedly connected to the outer wall of the discharge pipe, a fixing plate two fixedly connected to the outer wall of the fixing plate one, and an adjustment component provided inside the discharge pipe;
[0007] The adjusting assembly includes an adjusting plate, the outer wall of which is slidably connected to the inside of the discharge pipe.

[0008] Furthermore, a collection box one is fixedly connected to the inner wall of the support base, a collection box two is fixedly connected to the outer wall of the support base, and a screening component is provided inside the support base.
[0009] Furthermore, the screening assembly includes a screen plate disposed inside a support base. A fixing block two is fixedly connected to the outer wall of the screen plate. A fixing plate four is fixedly connected to the outer wall of the fixing block two. A rotating plate is rotatably connected to the inner wall of the fixing plate four.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar parts.
[0026] Referring to Figures 1-4, one embodiment of this utility model is provided: a vibrating screen device for preventing blockage at the discharge port of a granulator, including a support base 1, a discharge pipe 2 fixedly connected to the inner wall of the support base 1, the size of the discharge port is adjusted by the movement of the adjusting plate 12 to ensure that the granules are output at the controlled flow rate, a fixing plate 5 fixedly connected to the outer wall of the discharge pipe 2 to provide installation support for components such as electric push rod 7, gear 9, and single-sided rack 10, and the sliding groove on the inner wall of the fixing plate 6 provides motion guidance for the single-sided rack 10 and connecting rod 11, the fixing plate 6 fixedly connected to the outer wall of the fixing plate 5, and an adjusting component is provided inside the discharge pipe 2;
[0027] The adjustment assembly includes an adjustment plate 12 that slides inside the discharge pipe 2. By changing its position, it adjusts the cross-sectional area of the discharge port, thereby controlling the discharge speed and preventing the accumulation and blockage of granular material. The outer wall of the adjustment plate 12 is slidably connected to the inside of the discharge pipe 2. A connecting rod 11 is fixedly connected to the outer wall of the adjustment plate 12, transmitting the movement of the single-sided rack 10, causing the adjustment plate 12 to reciprocate inside the discharge pipe 2, thus achieving position control of the adjustment plate 12. One end of the connecting rod 11 is fixedly connected to the single-sided rack 10, which slides in a groove on the inner wall of the fixed plate 2. The connecting rod 11 pulls the adjustment plate 12. The moving and fixed plate 5 has an electric push rod 7 fixedly connected to its inner wall. The electric push rod 7 provides a power source through the linear motion of its output end, which drives the double-sided rack 8 to move. It is the core power structure for adjusting the size of the discharge port. The output end of the electric push rod 7 is fixedly connected to the double-sided rack 8. The horizontal movement of the rack 8 is converted into the rotational motion of the gear 9 through gear meshing. The fixed plate 5 has a gear 9 inside, which converts the motion of the double-sided rack 8 into the linear motion of the single-sided rack 10. The double-sided rack 8 meshes with the gear 9, and the gear 9 meshes with the single-sided rack 10.
[0028] Specifically, the granular material is first conveyed to the screen plate 13 through the discharge pipe 2. During this process, the output end of the electric push rod 7 moves linearly along the guide groove on the inner wall of the fixed plate 2 6, pushing the double-sided rack 8 to move horizontally synchronously. Since the double-sided rack 8 is precisely meshed with the gears 9 on both sides, its linear motion is converted into the rotational motion of the gears 9. The gears 9 then mesh with the single-sided rack 10, thereby driving the single-sided rack 10 to slide in the groove on the inner wall of the fixed plate 2 6. The adjusting plate 12 is pulled by the connecting rod 11 to reciprocate inside the discharge pipe 2. When the adjusting plate 12 moves towards the outlet of the discharge pipe 2, the cross-sectional area of the discharge port decreases, which can slow down the discharge speed. Conversely, the cross-sectional area increases, which speeds up the discharge speed. This achieves the effect of precisely adjusting the opening size of the discharge pipe 2, effectively preventing the granular material from accumulating and clogging inside the discharge pipe 2 due to uneven flow rate.
[0029] Referring to Figures 1 and 5, a collection box 3 is fixedly connected to the inner wall of the support base 1, and a collection box 4 is fixedly connected to the outer wall of the support base 1. A screening assembly is installed inside the support base 1, including a screen plate 13. The screen plate 13 moves the granules by shaking itself, thus separating particles of different sizes. The screen plate 13 is located inside the support base 1. A fixing block 25 is fixedly connected to the outer wall of the screen plate 13. A fixing plate 26 is fixedly connected to the outer wall of the fixing block 25. A rotating plate 24 is rotatably connected to the inner wall of the fixing plate 26. The rotation of the fixing plate 26 is converted into the shaking power of the screen plate 13 through the lever principle. To enhance the screening effect, a fixed plate 23 is rotatably connected to the outer wall of the rotating plate 24. A fixed block 22 is fixedly connected to the outer wall of the fixed plate 23. A fixed seat 14 is fixedly connected to the outer wall of the fixed block 22. A dual-shaft motor 15 is fixedly connected to the inner wall of the fixed seat 14. The motor drives the connecting rods 16 and 17 to rotate simultaneously through its two output ends, providing power for the screening operation. The dual-shaft motor 15 has connecting rods 16 and 17 fixedly connected to its two output ends, respectively. An eccentric wheel 18 is fixedly connected to one end of the connecting rod 17. The column 19 rotates eccentrically, converting the rotational motion into the oscillating power of the connecting rod 20 using an eccentric structure. The outer wall of the eccentric wheel 18 is rotatably connected to the fixed column 19, providing a support shaft for the rotation of the eccentric wheel 18 and ensuring its stable rotation. The outer wall of the eccentric wheel 18 is rotatably connected to the connecting rod 20, which oscillates around the fixed rod 21 under the push of the eccentric wheel 18, transmitting the motion of the eccentric wheel 18 to the fixed rod 21, causing the screen plate 13 to shake. The inner wall of the connecting rod 20 is rotatably connected to the fixed rod 21. The outer wall of the fixed column 19 is fixedly connected to one side of the outer wall of the fixed seat 14. One end of the fixed rod 21 is fixedly connected to the outer wall of the sieve plate 13. The outer wall of the connecting rod 17 is rotatably connected to the inner wall of the fixed seat 14. The outer wall of the connecting rod 16 is rotatably connected to the inner wall of the fixed seat 14. The outer wall of the electric push rod 7 is slidably connected to the inner wall of the fixed plate 6. The outer wall of the adjusting plate 12 is slidably connected to the inner wall of the fixed plate 5. The outer wall of the connecting rod 11 is slidably connected to the inner wall of the fixed plate 5. The outer wall of the connecting rod 11 is slidably connected to the inner wall of the fixed plate 6. The lower surface of the fixed seat 14 is fixedly connected to the upper surface of the collection box 3. The rotating plate 24 is set on one side of the outer wall of the sieve plate 13 and the fixed seat 14.
[0030] Specifically, after the granular material falls above the screen plate 13, the dual-shaft motor 15 is started, and its two output ends drive the connecting rod 2 16 and the connecting rod 3 17 to rotate respectively. The connecting rod 3 17 drives the eccentric wheel 18 to rotate eccentrically around the fixed column 19. The flange on the outer wall of the eccentric wheel 18 pushes the connecting rod 4 20 to swing around the fixed rod 21. The fixed rod 21 is fixedly connected to the screen plate 13, thereby causing the screen plate 13 to reciprocate. At the same time, the two ends of the rotating plate 24 slide in the rotating grooves on the inner walls of the fixed plate 4 26 and the fixed plate 3 23 respectively. The swing amplitude of the screen plate 13 is amplified by the lever principle, so that smaller particles fall directly into the collection box 1 3 through the screen holes of the screen plate 13, while larger particles slide down the inclined surface of the screen plate 13 into the collection box 2 4 for collection, realizing automated grading and screening operation.
[0031] Working principle: When the anti-clogging vibrating screen device at the discharge port of the granulator is needed, the granules are first conveyed to the screen plate 13 through the discharge pipe 2. During this process, the double-sided rack 8 can be moved by the output end of the electric push rod 7. Because the double-sided rack 8 meshes with the gears 9 on both sides, the movement of the double-sided rack 8 can drive the gears 9 to rotate. Because the gears 9 mesh with the single-sided rack 10, the rotation of the gears 9 will drive the single-sided rack 10 to slide on the inner wall of the fixed plate 2 6, thereby driving the connecting rod 11 and the adjusting plate 12 to move. This achieves the effect of adjusting the opening size of the discharge pipe 2, effectively preventing the granules from accumulating inside the discharge pipe 2 and causing blockage.
[0032] In addition, when the granules fall above the screen plate 13, the dual-shaft motor 15 is started. The two output ends of the dual-shaft motor 15 drive the eccentric wheel 18 to rotate, thereby driving the connecting rod 20 to pull the fixed rod 21 to move, causing the screen plate 13 to shake. During this process, the rotating plate 24 rotates along the inner wall of the fixed plate 26 and the fixed plate 23, which can effectively screen the granules. Smaller granules fall directly into the collection box 3, while larger granules slide through the screen plate 13 into the collection box 4 for collection.
[0033] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
[0034] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
