Description

Technical Field

[0001] This utility model relates to the field of wet granulation machine technology, specifically to a vibrating screening mechanism and a wet granulation machine containing the mechanism. Background Technology

[0002] Wet granulation machines are devices that form granules from powder by adding binders. They are widely used in industries such as pharmaceuticals, food, feed, and ceramics. The core process involves mixing powder and binder to form a moist, soft material, which is then cut into uniform granules.

[0003] In conventional vibrating screening mechanisms used in wet granulation, the top cover is prone to shaking due to vibration or improper operation during material feeding, leading to material spillage. This not only wastes material but also affects the cleanliness of the production environment. Moreover, conventional mechanisms lack effective vibration damping measures, and the significant vibrations generated during operation are transmitted to various components. Over time, these components are prone to loosening, wear, or even breakage, greatly shortening the equipment's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening mechanism and a wet granulation machine containing the mechanism, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screening mechanism and a wet granulation machine containing the mechanism, comprising a screening box and a top cover component. The top cover component is embeddedly connected to the top of the screening box, and a vibrating mechanism is installed on both the front and rear sides of the screening box. Furthermore, support pillars are symmetrically and vertically installed at the lower ends of the left and right sides of the screening box. The top cover component includes a cover plate, a feed hood, a feed inlet, a double-stage damping hinge, and a support base. The top of the cover plate is provided with a feed hood, and the feed inlet is provided in the middle of the feed hood. Furthermore, double-stage damping hinges are symmetrically installed on the left and right rear ends of the top of the cover plate, and a support base is connected to the end of the double-stage damping hinge away from the cover plate.

[0006] Furthermore, the screening box includes a main body, a support frame, a screening screen plate, and fixed corner plates. The support frame is provided on the upper inner surface of the main body, and the screening screen plate is provided on the bottom inner side of the main body. Fixed corner plates are installed at equal intervals at both the front and rear ends of the bottom of the screening screen plate.

[0007] Furthermore, the main housing and the support frame are welded together, and the bottom of the cover plate is abutted against the top surface of the support frame and embedded inside the top of the main housing.

[0008] Furthermore, the support base is installed on the upper rear side of the main housing, and the cover plate, the double-section damping hinge, the support base, and the main housing are connected by a modular structure. Moreover, the double-section damping hinge near the main housing and the four diagonal corners of the connection between the double-section damping hinge and the support base are provided with holes for bolt installation.

[0009] Furthermore, the vibration mechanism includes a vibration motor, a docking seat, and a fixed seat. The vibration motor has docking seats at both ends, and the fixed seat is connected to the side of the docking seat away from the vibration motor.

[0010] Furthermore, the docking seat has four diagonal holes for bolt installation at the four corners of the side near the vibration motor, and the fixing seat has multiple sets of holes for bolt installation on the side surface near the main housing.

[0011] Furthermore, the support structure includes a spring support column, a stabilizing pile, and a connecting seat. The top of the spring support column is equipped with a stabilizing pile, and the side of the stabilizing pile near the screening box of the connecting seat is connected to the connecting seat. The connecting seat has holes for bolt installation at its four opposite corners. The upper and lower ends of the spring support column and the four opposite corners of the bottom end of the stabilizing pile also have holes for bolt installation.

[0012] A wet granulation machine is provided, which is equipped with a vibrating screening mechanism as described above.

[0013] This utility model provides a vibrating screening mechanism and a wet granulation machine containing the mechanism, which has the following beneficial effects: 1. This utility model features a top cover component installed on the top of the screening box. The structure, utilizing a double-segment damping hinge and support base, ensures smooth and stable opening of the cover, facilitating material feeding and cleaning / maintenance of the screening box. The modular connection method also streamlines the assembly and disassembly of the screening box and top cover component, improving equipment flexibility and maintenance efficiency. It also prevents material spillage caused by cover wobbling during feeding. Furthermore, the feed hood and inlet design within the top cover component allow for accurate and rapid material entry into the screening box, further enhancing operational efficiency. Combined with the internal support frame of the main body, this provides stability for the top cover. The screen is properly supported to ensure a tight connection between the cover plate and the main body during the vibrating screening process, preventing loosening or displacement due to vibration. This ensures the stability and reliability of the screening operation. Furthermore, the screen plates inside the screening box have fixed corner plates evenly spaced at both ends of their bottom. This not only enhances the structural strength of the screen plates but also keeps them flat during vibration, effectively preventing deformation caused by material gravity or vibration. This ensures the uniformity and accuracy of the screened particle size, improving the quality of wet granulation. Additionally, multiple sets of screen plates with different filter mesh sizes can be replaced or added as needed to achieve multi-stage screening and allow for flexible adjustments based on different particle size requirements, meeting diverse production needs.

[0014] 2. This utility model, by installing support pillars at the lower ends of the left and right sides of the screening box, utilizes a structural design of spring support pillars in conjunction with stabilizing piles and connecting seats. This effectively absorbs and buffers the impact force generated by vibration during equipment operation, reducing the overall vibration amplitude of the equipment, minimizing fatigue damage to various components caused by vibration, and extending the service life of the equipment. Simultaneously, the holes for bolt installation at the upper and lower ends of the stabilizing piles, connecting seats, and spring support pillars facilitate a stable connection between the support pillars and the screening box, ensuring reliable support of the screening box and guaranteeing the stability of the equipment during operation. This provides a solid support foundation for the vibrating screening mechanism. Furthermore, this structural design makes the installation and disassembly of the support pillars convenient, facilitating equipment transportation, installation, and maintenance. Additionally, the vibrating motor in the vibration mechanism is connected to the fixed seat at the front and rear of the screening box via a docking seat. The holes on the side, connecting seat, and fixed seat for bolt installation ensure a secure connection between the vibrating motor and the screening box. This allows the vibrating motor to stably transmit power to the screening box, driving it to perform effective vibratory screening and ensuring optimal screening results. This connection method also facilitates the inspection and maintenance of the vibrating motor. In case of motor failure, it can be easily disassembled and replaced, reducing downtime and improving production efficiency. When applied to wet granulation machines, this vibrating screening mechanism significantly enhances the overall performance. After powder and binder are mixed to form a moist soft material, the vibrating screening mechanism can quickly and accurately cut the soft material into uniform particles, improving particle quality and consistency. This meets the high requirements of the pharmaceutical, food, feed, and ceramic industries for granular products, providing a highly efficient and reliable equipment solution for related industries.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 6As shown, a vibrating screening mechanism and a wet granulation machine containing the mechanism include a screening box 1 and a top cover component 2. The top cover component 2 is embedded in the top of the screening box 1, and vibrating mechanisms 3 are installed on both the front and rear sides of the screening box 1. Support components 4 are symmetrically and vertically installed at the lower ends of both the left and right sides of the screening box 1. The top cover component 2 includes a cover plate 201, a feed hood 202, a feed inlet 203, a double-stage damping hinge 204, and a support base 205. The feed hood 202 is located on the top of the cover plate 201. A feed inlet 203 is provided in the middle of the feed hood 202, and double-stage damping hinges 204 are symmetrically installed on the left and right sides of the top rear end of the cover plate 201. A support base 205 is connected to the end of the double-stage damping hinge 204 away from the cover plate 201. The screening box 1 includes a main box body 101, a support frame 102, a screening screen plate 103, and a fixed corner plate 104. The support frame 102 is provided on the upper inner surface of the main box body 101, and the screening screen plate 103 is provided on the bottom inner side of the main box body 101. Fixed corner plates 104 are equidistantly arranged at both the front and rear ends of the bottom of the 3-shaped housing. The main housing 101 and the support frame 102 are welded together, and the bottom of the cover plate 201 is abutted against the top surface of the support frame 102 and embedded inside the top of the main housing 101. The support base 205 is installed on the upper rear side of the main housing 101. The cover plate 201, the double-stage damping hinge 204, the support base 205, and the main housing 101 are connected in a modular structure. The double-stage damping hinge 204 is close to the main housing 101. Holes for bolt installation are provided at one end and at the four diagonal corners where the double-segment damping hinge 204 and the support base 205 connect. The structure of the double-segment damping hinge 204 and the support base 205 allows the cover plate 201 to move smoothly along a preset trajectory during opening, avoiding damage to the equipment caused by the impact force generated by sudden opening or closing. At the same time, this design also makes it easy for the operator to operate the cover plate 201 to open and close with one hand, improving the convenience and safety of operation.

[0019] like Figures 1 to 6As shown, the vibration mechanism 3 includes a vibration motor 301, a docking seat 302, and a fixed seat 303. The vibration motor 301 has docking seats 302 at both ends, and the fixed seat 303 is connected to the side of the docking seat 302 furthest from the vibration motor 301. The docking seat 302 has four diagonal holes for bolt installation on the side closest to the vibration motor 301. The fixed seat 303 has multiple sets of holes for bolt installation on the surface of the side closest to the main housing 101. The support member 4 includes a spring support column 401, a stabilizing pile 402, and a connecting seat 403, with a stabilizing pile installed on the top of the spring support column 401. 402, and the stabilizing pile 402 is connected to the connecting seat 403 on the side of the screening box 1 near the connecting seat 403. The connecting seat 403 has holes for bolt installation at the four opposite corners. The upper and lower ends of the spring support column 401 and the four opposite corners of the bottom end of the stabilizing pile 402 also have holes for bolt installation. The elasticity of the spring support column 401 can effectively reduce the impact force generated by the vibration motor 301 when it is working, and prevent these impact forces from being directly transmitted to other parts of the equipment, thereby reducing the wear and failure of the equipment caused by long-term vibration and extending the overall service life of the equipment.

[0020] With the above-described structure, when the vibration motor 301 starts, the generated vibration energy is first transmitted to the screening box 1 through the docking seat 302 and the fixed seat 303. The screening box 1 then vibrates at a high frequency. The support pillars 4 installed at the lower ends of the left and right sides of the screening box 1 then begin to function. When the spring support pillars 401 are subjected to the pressure generated by the vibration, they will quickly undergo elastic deformation, converting most of the vibration energy into their own elastic potential energy, and then slowly releasing it. This process effectively reduces the overall vibration amplitude of the screening box 1. The stabilizing piles 402, through their solid connection with the connecting seat 403, ensure... The support member 4 maintains structural stability when absorbing vibration, preventing loosening or displacement of the member due to excessive vibration. At the same time, the multiple bolt mounting holes on the connecting seat 403 provide more fixing points for the connection between the support member 4 and the screening box 1, enhancing the firmness and reliability of the connection. In addition, during vibration, the screening screen 103 inside the screening box 1 maintains the flatness and stability of the screen through the fixed corner plates 104 installed at equal intervals at the bottom, so that the material can be evenly stressed when passing through the screening screen 103, thereby achieving a more accurate screening effect.

[0021] In summary, as Figures 1 to 4As shown, when using the vibrating screening mechanism and the wet granulation machine containing the mechanism, the operator first pours the wet soft material formed by mixing the powder to be screened with the binder into the screening box 1 through the feed port 203 in the feed hood 202. At this time, the vibration motor 301 in the vibration mechanism 3 is started. The vibration motor 301 is stably connected to the front and rear sides of the screening box 1 through the docking seat 302 and the fixed seat 303, and starts to work and generate vibration. The vibration generated by the vibrating motor 301 is efficiently transmitted to the screening box 1 through the fixed seat 303 and the docking seat 302. The screening box 1 then vibrates regularly. The wet soft material inside is subjected to vibration on the screening screen plate 103 and keeps jumping and rolling. Since the fixed corner plates 104 are installed at equal intervals at the front and rear ends of the bottom of the screening screen plate 103, the screening screen plate 103 remains flat during vibration. During the jumping and rolling of the wet soft material, the particles that meet the particle size requirements will fall through the holes on the screening screen plate 103, while the particles that do not meet the particle size requirements will remain on the screening screen plate 103 and continue to be vibrated and screened. Meanwhile, the support pillars 4 installed at the lower ends of the left and right sides of the screening box 1 play an important role. The spring support pillar 401 utilizes its elastic properties to effectively absorb and buffer the impact force generated by vibration, reduce the overall vibration amplitude of the equipment, and reduce fatigue damage to various parts of the equipment caused by vibration. The stabilizing pile 402, the connecting seat 403, and the holes for bolt installation at the upper and lower ends of the spring support pillar 401 ensure a stable connection between the support pillar 4 and the screening box 1, enabling the support pillar 4 to reliably support the screening box 1 and ensure the stability of the equipment during operation. Throughout the screening process, operators can observe the screening situation and replace or add multiple sets of screening screens 103 with different filter mesh sizes as needed to achieve multi-stage screening and meet the production needs of granular products with different particle size requirements. After the screening work is completed, operators can easily open the cover 201 through the double-stage damping hinge 204 to clean and maintain the inside of the screening box 1, preparing for the next screening operation.
