Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer device technology, specifically to a raw material conveying buffer device. Background Technology
[0002] The supply of raw materials required for the production of polyurethane adhesives, such as isocyanates and polyols, may fluctuate due to factors such as transportation and storage. The raw material conveying buffer device can store a certain amount of raw materials when the supply is sufficient, and continuously convey them to the production process when the supply is insufficient, so as to prevent production interruption due to raw material shortage. If the arrival of raw materials is delayed due to traffic jams during transportation, the raw materials stored in the buffer device can maintain the normal operation of the production line.
[0003] The existing technology has the following problems: The existing equipment cannot seal the gap between the buffer tube and the storage tank during use. If the gap is not sealed when the raw material flows between the buffer tube and the storage tank, the raw material may leak out. This not only reduces the actual amount of raw material used and affects the continuity of production, but also causes raw material waste and increases production costs. In addition, the existing equipment cannot adjust the flow rate during material feeding. If the flow rate cannot be adjusted, the equipment can only feed material at a fixed rate. This will either cause the initial feeding to be too fast, making the reaction difficult to control, or the later feeding to be too slow, slowing down the production progress and reducing the overall production efficiency.

Detailed Implementation
[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.
[0015] like Figure 1 As shown, this utility model provides a raw material conveying and buffering device, including a conveying pipe 1, a buffer pipe 2 fixedly connected to the outer wall of the conveying pipe 1, a storage box 5 arranged below the conveying pipe 1, a vacuum pump 6 fixedly connected to the left side of the storage box 5, the output pipe of the vacuum pump 6 fixedly connected to the storage box 5, a conduit 4 fixedly connected to the rear side of the storage box 5, a valve arranged inside the conduit 4, a sealing seat 3 fixedly connected to the outer wall of the conduit 4, the rear side of the sealing seat 3 movably connected to the buffer pipe 2, a discharge pipe 7 fixedly connected to the front side of the storage box 5, a fixing column 8 fixedly connected to the outer wall of the discharge pipe 7, and the conveying pipe 1 serves as the main channel for raw material input, with the buffer pipe fixedly connected to its outer wall. 2. Raw materials can be stored when the supply is sufficient. The storage box 5 set below the conveying pipe 1 is used to further store raw materials. The air pump 6 connected on the left can extract air from the storage box 5 to adjust the pressure and other conditions inside the storage box 5, which is beneficial to the storage and transportation of raw materials. The storage box 5 is connected to the buffer pipe 2 through the conduit 4 at the rear. The valve inside the conduit 4 can control the flow of raw materials between the two. The sealing seat 3 is connected to the outer wall of the conduit 4 to achieve a sealed connection with the buffer pipe 2. The discharge pipe 7 on the front of the storage box 5 is used to discharge the raw materials in the storage box 5 to the production stage. The fixing column 8 fixed on the outer wall of the discharge pipe 7 provides the installation foundation for subsequent flow rate adjustment and other operations.
[0016] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, two connecting plates 9 are fixedly connected to the outer wall of the buffer tube 2, and two threaded posts 10 are fixedly connected to the rear side of the sealing seat 3. The outer wall of the threaded post 10 is movably connected to the connecting plate 9. A threaded ring 11 is provided on the rear side of the connecting plate 9, and the outer wall of the threaded post 10 is threadedly connected to the threaded ring 11. A knob 12 is rotatably connected to the rear side of the sealing seat 3, and a threaded rod 13 is fixedly connected to the front side of the knob 12. A movable ring 15 is threadedly connected to the outer wall of the threaded rod 13. A limiting post 14 is fixedly connected to the inner surface of the sealing seat 3. The outer wall of the limiting post 14 is slidably connected to the moving ring 15. A sealing ring 30 is fixedly connected to the inner surface of the sealing seat 3. The outer wall of the buffer tube 2 is movably connected to the sealing ring 30. Multiple movable blocks 16 are fixedly connected to the front side of the moving ring 15. A slanted groove 17 is opened through the left side of the movable block 16. A guide post 18 is slidably connected to the inner surface of the slanted groove 17. A pressing block 19 is fixedly connected to the outer wall of the guide post 18. The outer wall of the sealing ring 30 is movably connected to the pressing block 19. The inner surface of the sealing seat 3 is fixedly connected with multiple limiting plates 20. The outer wall of the limiting plate 20 is slidably connected to the extrusion block 19. The connecting plate 9 on the outer wall of the buffer tube 2 cooperates with the threaded post 10 on the rear side of the sealing seat 3 and is tightened by the threaded ring 11 on the rear side to initially fix the relative position of the sealing seat 3 and the buffer tube 2. When the knob 12 on the rear side of the sealing seat 3 is rotated, the knob 12 drives the threaded rod 13 connected on the front side to rotate. Since the threaded rod 13 is threadedly connected to the moving ring 15 and the moving ring 15 is limited by the limiting post 14, the sealing seat 3 is initially fixed to the relative position of the buffer tube 2. The movement ring 15 can only slide along the direction of the limiting post 14, so the moving ring 15 will move forward or backward when the threaded rod 13 rotates. The movable block 16 fixed on the front side of the moving ring 15 moves with the moving ring 15. The guide post 18 sliding in the inclined groove 17 on the movable block 16 will drive the extrusion block 19 to move radially under the restriction of the limiting plate 20. The extrusion block 19 extrudes the sealing ring 30, so that it fits tightly against the outer wall of the buffer tube 2, thereby sealing the gap between the buffer tube 2 and the storage box 5 to prevent raw material leakage and impurities from entering.
[0017] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a motor 21 is fixedly connected to the outer wall of the fixed column 8, a first bevel gear 28 is fixedly connected to the output shaft of the motor 21, a protective shell 23 is fixedly connected to the inner surface of the fixed column 8, a fixing ring 24 is fixedly connected to the inner surface of the fixed column 8, a semi-circular fixing plate 27 is fixedly connected to the inner surface of the fixing ring 24, a flow monitoring device 22 is fixedly connected to the outer wall of the fixed column 8, a second bevel gear 29 is meshed with the outer wall of the first bevel gear 28, a rotating shaft 26 is fixedly connected to the rear side of the second bevel gear 29, the outer wall of the rotating shaft 26 is rotatably connected to the protective shell 23, and a semi-circular rotating plate 25 is fixedly connected to the rear end of the rotating shaft 26. When the motor 21 on the outer wall of the fixed column 8 is started, its output shaft drives... The first bevel gear 28 rotates, meshing with the second bevel gear 29, causing the rotating shaft 26 connected to the rear side of the second bevel gear 29 to rotate within the protective shell 23. The semi-circular rotating plate 25 fixed at the rear end of the rotating shaft 26 rotates with the rotating shaft 26, while the semi-circular fixing plate 27 fixed on the inner surface of the fixing ring 24 remains in a fixed position. As the semi-circular rotating plate 25 rotates, the gap between it and the semi-circular fixing plate 27 changes, thereby changing the cross-sectional area through which the raw material passes in the discharge pipe 7, thus achieving flow regulation. The flow monitoring device 22 can monitor the flow rate of the raw material in the discharge pipe 7 in real time, providing data reference for flow regulation and ensuring that the raw material flow rate can be accurately adjusted according to actual needs during the production process, adapting to the requirements of raw material flow rate at different production stages.
[0018] The working principle of this raw material conveying and buffering device will be explained in detail below.
[0019] like Figure 1-5As shown, when the knob 12 on the rear side of the sealing seat 3 is rotated, the knob 12 drives the threaded rod 13 connected to the front side to rotate. Since the threaded rod 13 is threadedly connected to the moving ring 15, and the moving ring 15 is restricted by the limiting post 14 and can only slide along the direction of the limiting post 14, the moving ring 15 will move forward or backward when the threaded rod 13 rotates. The movable block 16 fixed on the front side of the moving ring 15 moves with the moving ring 15. The guide post 18 sliding in the inclined groove 17 on the movable block 16 will drive the extrusion block 19 to move radially under the restriction of the limiting plate 20. The extrusion block 19 extrudes the sealing ring 30, making it tightly fit the outer wall of the buffer tube 2, thereby sealing the gap between the buffer tube 2 and the storage box 5, preventing raw material leakage and impurity intrusion. The motor 21 on the outer wall of the fixed post 8 starts. When the output shaft drives the first bevel gear 28 to rotate, the first bevel gear 28 meshes with the second bevel gear 29, causing the rotating shaft 26 connected to the rear side of the second bevel gear 29 to rotate inside the protective shell 23. The semi-circular rotating plate 25 fixed at the rear end of the rotating shaft 26 rotates with the rotating shaft 26, while the semi-circular fixing plate 27 fixed on the inner surface of the fixing ring 24 is fixed in position. As the semi-circular rotating plate 25 rotates, the gap between it and the semi-circular fixing plate 27 will change, thereby changing the cross-sectional area through which the raw material passes in the discharge pipe 7, realizing flow regulation. The flow monitoring device 22 can monitor the flow rate of the raw material in the discharge pipe 7 in real time, providing data reference for flow regulation, ensuring that the raw material flow rate can be accurately adjusted according to actual needs during the production process, and adapting to the requirements of raw material flow rate at different production stages.
