Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, specifically to a raw material screening device for the production of fumed silicone rubber. Background Technology

[0002] In the production process of fumed silicone rubber, the quality of raw materials plays a crucial role in the performance of the final product. High-quality raw materials ensure that fumed silicone rubber possesses excellent physical and chemical properties, such as superior elasticity, resistance to high and low temperatures, and insulation. Therefore, effective screening of raw materials for production is a key step in the fumed silicone rubber production process.

[0003] A search revealed Chinese patent application number 202021296066.7, which discloses a screening device for processing rubber raw materials. The device includes a base plate, a receiving box fixedly connected to the top of the base plate, a first support column fixedly connected to the right side of the top of the base plate, a support plate fixedly connected to the top right side of the first support column, and a buffer mechanism provided on the right side of the top of the support plate. This invention achieves good screening effect and convenient feeding and discharging by coordinating the base plate, receiving box, first support column, support plate, buffer mechanism, second support column, shell, reciprocating mechanism, anti-sway mechanism, moving plate, moving column, screening shell, and screening screen. It solves the problems of poor screening effect and inconvenient feeding and discharging in existing screening devices. When using the screening device, materials can be uniformly screened without affecting the screening quality. Raw materials can be added for screening in a timely manner, and the screened raw materials can be collected, making it convenient for users.

[0004] Although the aforementioned patents solve the problems of poor screening effect and inconvenient feeding and discharging of existing screening devices, allowing for uniform screening of materials without affecting screening quality, timely addition of raw materials for screening, and collection of screened raw materials, the use of a single screen in actual use results in low screening efficiency and an inability to perform multi-level and precise screening of raw materials. Furthermore, screen replacement is not convenient. When the screen is damaged due to prolonged use or needs to be replaced with a screen of different mesh size according to different production needs, it often requires a lot of time and manpower, affecting the continuity and efficiency of production.

[0005] Therefore, it is necessary to modify it by setting up a multi-stage screening structure to accurately screen raw materials, improve the quality of raw materials, and at the same time, the screens can be easily disassembled and replaced as needed, thereby improving the applicability and production efficiency of the equipment.

Moving rods 12 are fixedly connected to the output ends of the double-headed electric telescopic rod 11 on both the left and right sides. Several L-shaped rods 13 that cooperate with the ear plates 10 are fixedly connected to the back of the moving rods 12. The bottom of the rear end of the L-shaped rods 13 is attached to the top of the ear plates 10.

[0019] refer to Figure 1 Support rods 14 are fixedly connected to the left and right sides of the bottom of the front frame 8. The bottom of the support rod 14 is provided with a square groove, and a roller 15 is rotatably connected inside the square groove through a shaft. The bottom of the roller 15 is in contact with the top of the worktable 1.

[0020] As a technical optimization of this utility model, a support rod 14 is set at the bottom of the front frame 8. The bottom of the support rod 14 is rotatably connected to a roller 15 via a shaft. The roller 15 fits against the top of the worktable 1, making the front frame 8 move more smoothly during vibration, reducing friction between it and the worktable 1, lowering energy consumption during device operation, and extending the service life of the device. At the same time, the roller 15 also ensures that the screen frame 9 maintains a stable movement trajectory during vibration, making the screening process more stable and further improving the accuracy and efficiency of screening.

The material receiving interface 17 is located below the screen frame 9, which can collect the screened raw materials in a timely manner, avoid the raw materials from scattering, and keep the working environment clean. The design of the insertion slot 18 and the material receiving box 19 facilitates the centralized processing of the collected raw materials, which is convenient for subsequent production and processing. The pluggable structure of the material receiving box 19 makes the collection and cleaning of raw materials more convenient and faster, improves production efficiency, and reduces the workload of manual operation.

The sliding sleeve 20 reduces the friction between the round rod 3 and the circular groove, making the sliding of the round rod 3 within the circular groove smoother, reducing the resistance when the vibration motor 5 is driven, and improving energy utilization efficiency. At the same time, the sliding sleeve 20 also plays a certain buffering role, reducing wear between the round rod 3 and the circular groove, extending the service life of the device, and ensuring the long-term stable operation of the device.

[0027] refer to Figure 2A magnetic plate 21 is fixedly connected to the rear side of the bottom of the workbench 1, and a metal strip is fixedly connected to the back of the receiving box 19. The front of the magnetic plate 21 is magnetically connected to the back of the metal strip.

[0028] As a technical optimization of this utility model, a magnetic plate 21 is fixed to the rear side of the bottom of the workbench 1, and a metal strip is fixed to the back of the receiving box 19. The magnetic plate 21 and the metal strip are magnetically connected, so that the receiving box 19 can be firmly fixed under the workbench 1, preventing the receiving box 19 from shaking or shifting during the operation of the device, and ensuring that the raw materials can fall accurately into the receiving box 19. The magnetic connection also facilitates the installation and removal of the receiving box 19. When the receiving box 19 is full of raw materials and needs to be cleaned, it can be easily removed from under the workbench 1, improving the convenience of operation and production efficiency.

[0029] The working principle and usage process of this utility model are as follows: In use, the raw material for fumed silicone rubber production is placed on the uppermost screen frame 9. The vibration motor 5 is started, and the generated vibration is transmitted to the push-pull plate 4. The push-pull plate 4 slides within the circular grooves at the four corners of the back plate 2 via the round rod 3. Simultaneously, the tension spring 6 fitted on the surface of the round rod 3 acts as a buffer and assists in resetting, allowing the push-pull plate 4 to reciprocate within a certain range, providing vibration power to the screen frame 9. Larger particles of raw material remain in the upper screen frame 9, while smaller particles pass through the mesh of the upper screen frame 9 and enter the middle and lower screen frames 9 for further screening. Finally, the finest materials that meet the requirements fall into the collection box 19 through the collection interface 17. When it is necessary to replace the screen frame 9, the double-headed electric telescopic rod 11 is activated. The output ends on both sides of the telescopic rod 11 drive the moving rod 12 to move. The L-shaped rod 13 on the moving rod 12 moves with the moving rod 12, thereby detaching from the top of the ear plate 10 of the screen frame 9 and releasing the fixation on the screen frame 9. The screen frame 9 that needs to be replaced can be easily taken out from the placement beam 7, and then a new screen frame 9 can be installed. After installation, the double-headed electric telescopic rod 11 is started again, so that the L-shaped rod 13 re-fixes the ear plate 10 of the screen frame 9. After screening, each screen frame 9 can be taken out to clean the raw materials of different sizes remaining inside for the next use.
