Description

Technical Field

[0001] This utility model relates to the field of quantitative proportioning technology for remodelable phenolic resin raw materials, specifically to a quantitative proportioning device for remodelable phenolic resin raw materials. Background Technology

[0002] Phenolic resin is an important thermosetting resin material widely used in adhesives, molding compounds, coatings, and other fields. With the development of new material technologies, remodelable phenolic resin has gradually been applied in industries such as electronics, automobiles, and construction due to its thermoplasticity, reprocessability, and environmental advantages. In actual production, in order to ensure the stable performance of remodelable phenolic resin, it is usually necessary to quantitatively proportion various raw materials and mix them before putting them into subsequent processing stages.

[0003] When processing remodelable phenolic resin raw materials, these materials usually have a certain viscosity and may clump or adhere to the inner wall of the container during storage, causing the material to accumulate at the outlet, which in turn leads to poor discharge or even blockage. Especially during continuous batching, if the raw materials cannot flow out smoothly, it will not only lead to the accumulation of quantitative errors, but may also cause fluctuations in the concentration of raw materials in the mixing tank, seriously affecting the performance stability of the final product and the accuracy of process control. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative proportioning device for remodelable phenolic resin raw materials, in order to solve the problem that the quantitative proportioning device for remodelable phenolic resin raw materials proposed in the background art is prone to clumping or adhering to the inner wall of the container during storage, causing the material to accumulate at the discharge port, which in turn leads to poor discharge or even blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative proportioning device for remodelable phenolic resin raw materials, comprising a mixing tank, a support leg at the bottom of the mixing tank, a set of support frames at the top of the mixing tank, a drive motor on the support frames, a rotating shaft at the output end of the drive motor, the rotating shaft extending into the mixing tank, a mounting block on the support frames, a storage tank on the mounting block, remodelable phenolic resin raw materials placed in the storage tank, a discharge pipe at the bottom of the storage tank, and a quantitative component inside the mixing tank for quantitatively dispensing the remodelable phenolic resin raw materials into the storage tank.

[0006] Preferably, the metering component includes multiple sets of stabilizing supports disposed on the rotating shaft, each stabilizing support having a rotating ring, the rotating ring having a conveying pipe passing through it, and the top of the rotating ring being in contact with the discharge pipe.

[0007] Preferably, the mixing tank contains a set of fixed frames, each with a limiting ring and a feeding port. The feeding port is an arc shape bent to one side, and one end of the feeding port is adapted to the conveying pipe.

[0008] Preferably, a protruding block is provided on one side of the storage tank. The protruding block is an arc shape that bends to one side, and multiple sets of grooves are formed on the surface of the protruding block.

[0009] Preferably, a mounting ring is sleeved on the rotating shaft, and a guide rod is provided on the mounting ring. The guide rod is a telescopic structure, and a contact head is provided at one end of the guide rod. A return spring is sleeved on the guide rod, with one end of the return spring located on one side of the mounting ring and the other end of the return spring located on one side of the contact head.

[0010] Preferably, a telescopic tube is provided at the bottom of the feed port. The telescopic tube is a retractable pipe, and a float is provided at the bottom of the telescopic tube. The float can contact the remodelable phenolic resin raw material in the mixing tank.

[0011] Preferably, one end of the delivery pipe is in contact with one end of the limiting ring.

[0012] Preferably, the storage tank is trapezoidal in shape, tilted to one side, with the tilt direction consistent with the direction of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the quantitative proportioning of remodelable phenolic resin raw materials not only avoids material accumulation at the discharge port and improves the smoothness of discharge, but also avoids fluctuations in the raw material concentration in the mixing tank, thereby improving the performance stability of the product and the precision of process control.

[0014] As the rotating shaft rotates, the rotating ring and the conveying pipe rotate accordingly. When the conveying pipe rotates to the position aligned with the feeding port, the raw material falls from the discharge pipe into the feeding port through the conveying pipe, completing the quantitative dispensing. The rotating shaft drives the rotating ring to rotate, achieving periodic alignment between the conveying pipe and the feeding port, thus achieving the purpose of quantitative dispensing of raw materials. The arc-shaped feeding port design improves the smoothness and sealing of the feeding process, reducing leakage. The stabilizing bracket ensures structural stability during rotation, and the limiting ring plays a precise positioning role, thereby improving the accuracy and repeatability of the proportioning. This structure simplifies the mechanical structure of the quantitative mechanism, reduces the failure rate, and improves the degree of automation and raw material utilization.

[0015] As the rotating shaft rotates, the guide rod, under the elastic force of the return spring, periodically presses the contact head into the groove on the surface of the protruding block. When the contact head contacts the groove, an impact vibration is generated, which causes the storage tank body to vibrate slightly. This helps to promote the falling and smooth discharge of raw materials in the tank, reducing the problems of raw materials clumping, sticking to the walls, or difficulty in falling in the storage tank, and improving the smoothness and continuity of raw material feeding. The guide rod has a simple structure and, together with the return spring, can achieve automatic return and multiple repetitive actions, improving the reliability and efficiency of the device during operation and helping to ensure the accuracy and stability of quantitative proportioning.

[0016] The float can float on the surface of the remodelable phenolic resin raw material in the mixing tank, rising and falling with changes in the liquid level. This causes the telescopic tube to extend and retract accordingly, automatically adjusting the height between the feed inlet and the raw material in the mixing tank. This ensures that the raw material can smoothly enter the mixing area and avoids feeding difficulties or splashing due to changes in the liquid level. By sensing changes in the liquid level of the raw material in the mixing tank, the float drives the telescopic tube to extend and retract, achieving dynamic adaptation between the feed inlet and the liquid level, improving the stability and adaptability of feeding. Automatic adjustment can be achieved without additional sensors or control systems. The structure is simple and the response is sensitive. It effectively prevents raw material backflow, accumulation, or blockage, ensuring continuous and stable operation of the quantitative proportioning process, further enhancing the practicality and intelligence of the equipment.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model provides an embodiment of a remodelable phenolic resin raw material quantitative proportioning device, including a mixing tank 1, a support leg 2 at the bottom of the mixing tank 1, a set of support frames 3 at the top of the mixing tank 1, a drive motor 4 on the support frames 3, a rotating shaft 5 at the output end of the drive motor 4, the rotating shaft 5 extending into the mixing tank 1, an mounting block 6 on the support frames 3, a storage tank 7 on the mounting block 6, the remodelable phenolic resin raw material placed in the storage tank 7, a discharge pipe 8 at the bottom of the storage tank 7, the storage tank 7 being a trapezoidal shape inclined to one side, the inclination direction being consistent with the direction of the discharge pipe 8; a quantitative component is provided in the mixing tank 1, the quantitative component being used to quantitatively dispense the remodelable phenolic resin raw material in the storage tank 7;

[0028] By setting up a mixing tank 1 as a container for raw material proportioning and mixing, the bottom of the mixing tank 1 is supported by support legs 2, and the top is equipped with a support frame 3 for mounting the drive motor 4 and the storage tank 7; the drive motor 4 drives the rotating shaft 5 to rotate, thereby achieving full mixing of the materials inside the mixing tank 1; the raw materials are stored in the storage tank 7, which has a one-sided inclined trapezoidal structure, and flow towards the discharge pipe 8 along the inclined direction under the action of gravity, ensuring that the raw materials can be smoothly transported and reducing residue; the quantitative component installed in the mixing tank 1 is used to quantitatively control the remodelable phenolic resin raw materials in the storage tank 7, achieving precise dispensing and proportioning; improving proportioning accuracy; suitable for quantitative proportioning operations of remodelable phenolic resin, reducing manual intervention, and improving production efficiency and product quality;

[0029] The quantitative assembly includes multiple sets of stabilizing supports 11 mounted on the rotating shaft 5. Each stabilizing support 11 has a rotating ring 12, through which a conveying pipe 13 is installed. The top of the rotating ring 12 is in contact with the discharge pipe 8. Inside the mixing tank 1, there is a set of fixing frames 9, each with a limiting ring 10. The limiting ring 10 has a feeding port 14, which is an arc-shaped structure bent to one side. One end of the feeding port 14 is adapted to the conveying pipe 13. One end of the conveying pipe 13 is in contact with one end of the limiting ring 10.

[0030] As the rotating shaft 5 rotates, the rotating ring 12 and the conveying pipe 13 rotate accordingly. When the conveying pipe 13 rotates to the position aligned with the feeding port 14, the raw material falls from the discharge pipe 8 into the feeding port 14 through the conveying pipe 13, completing the quantitative feeding. The rotating shaft 5 drives the rotating ring 12 to rotate, realizing the periodic docking of the conveying pipe 13 and the feeding port 14, achieving the purpose of quantitative feeding of raw materials. The arc-shaped feeding port 14 design improves the smoothness and sealing of feeding, reducing leakage. The stabilizing bracket 11 ensures structural stability during rotation, and the limiting ring 10 plays a precise positioning role, thereby improving the accuracy and repeatability of the proportioning. This structure simplifies the mechanical structure of the quantitative mechanism, reduces the failure rate, and improves the degree of automation and raw material utilization.

[0031] A protruding block 15 is provided on one side of the storage tank 7. The protruding block 15 is an arc shape that bends to one side, and multiple sets of grooves are formed on the surface of the protruding block 15. An installation ring 16 is sleeved on the rotating shaft 5. A guide rod 17 is provided on the installation ring 16. The guide rod 17 is a telescopic structure. A contact head 19 is provided at one end of the guide rod 17. A return spring 18 is sleeved on the guide rod 17. One end of the return spring 18 is located on one side of the installation ring 16, and the other end of the return spring 18 is located on one side of the contact head 19.

[0032] As the rotating shaft 5 rotates, the guide rod 17, under the elastic force of the return spring 18, periodically presses the contact head 19 into the groove on the surface of the protruding block 15. When the contact head 19 contacts the groove, an impact vibration is generated, which causes the storage tank 7 body to vibrate slightly. This helps to promote the falling and smooth discharge of raw materials in the tank, reducing the problems of raw materials clumping, sticking to the wall, or not falling easily in the storage tank 7, and improving the smoothness and continuity of raw material feeding. The guide rod 17 has a simple structure and, together with the return spring 18, can realize automatic return and multiple repetitive actions, improving the reliability and working efficiency of the device during operation, and helping to ensure the accuracy and stability of quantitative proportioning.

[0033] A telescopic pipe 20 is provided at the bottom of the feed port 14. The telescopic pipe 20 is a telescopic pipe. A float 21 is provided at the bottom of the telescopic pipe 20. The float 21 can contact the remodelable phenolic resin raw material in the mixing tank 1.

[0034] The float 21 floats on the surface of the remodelable phenolic resin raw material in the mixing tank 1, rising and falling with changes in liquid level. This causes the telescopic tube 20 to extend and retract accordingly, automatically adjusting the height between the feed port 14 and the raw material in the mixing tank 1. This ensures that the raw material can smoothly enter the mixing area and avoids feeding difficulties or splashing due to changes in liquid level. By sensing changes in the liquid level of the raw material in the mixing tank 1, the float 21 drives the telescopic tube 20 to extend and retract, achieving dynamic adaptation between the feed port and the liquid surface, improving the stability and adaptability of feeding. Automatic adjustment can be achieved without additional sensors or control systems. The structure is simple and the response is sensitive. It effectively prevents raw material backflow, accumulation, or blockage, ensuring continuous and stable operation of the quantitative proportioning process, further enhancing the practicality and intelligence of the equipment.

[0035] Work steps

[0036] In this embodiment, the following steps are taken: First, as the rotating shaft 5 rotates, the rotating ring 12 and the conveying pipe 13 rotate accordingly. When the conveying pipe 13 rotates to the position aligned with the feeding port 14, the raw material falls from the discharge pipe 8 into the feeding port 14 through the conveying pipe 13, completing the quantitative feeding. The rotating shaft 5 drives the rotating ring 12 to rotate, achieving periodic docking between the conveying pipe 13 and the feeding port 14, thus achieving the purpose of quantitative feeding of raw materials. As the rotating shaft 5 rotates, the guide rod 17, under the elastic force of the return spring 18, periodically presses the contact head 19 into the groove on the surface of the protruding block 15. When the contact head 19 and the groove are aligned, the raw material is fed into the feeding port 14. At the moment of contact with the tank, an impact vibration is generated, which causes the storage tank 7 to vibrate slightly. This helps to promote the falling and smooth discharge of the raw materials in the tank, reducing the problems of raw materials clumping, sticking to the walls, or not falling easily in the storage tank 7, and improving the smoothness and continuity of raw material feeding. The float 21 can float on the surface of the remodelable phenolic resin raw material in the mixing tank 1 and rises and falls with the change of liquid level, which drives the telescopic tube 20 to extend and retract accordingly, thereby automatically adjusting the height position between the feed port 14 and the raw materials in the mixing tank 1, ensuring that the raw materials can smoothly enter the mixing area and avoiding feeding difficulties or splashing caused by changes in liquid level.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
