[0002] A curing agent is a chemical substance used in the process of curing or hardening materials under suitable conditions. It plays an important role in many fields and applications, such as coatings, adhesives, composites, and glues. The main function of a curing agent is to initiate or catalyze reactions that cause cross-linking or polymerization between chemicals in the material, thereby forming a robust structure. Curing agents can be single chemical substances or complexes composed of multiple components. They are typically combined with other ingredients in a formulation, such as resins, solvents, and fillers, to form the final cured system.

[0003] In existing technologies, liquid raw materials for curing agents are mainly metered and fed through a combination of a solenoid valve and a control panel. However, the solenoid valve has a certain response time, which often results in over-metering and some errors. Therefore, it is necessary to design a feeding and metering device for curing agent production to solve the above problems.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a feeding and metering device for curing agent production, comprising:

[0033] Fixative raw material tank 1 is equipped with a feeding and metering mechanism. It should be noted that it can perform precise feeding and metering to ensure the accuracy of the metering.

[0034] The feeding and metering mechanism includes a metering cylinder 3, a feeding pipe 4, a solenoid valve 5, a side plate 6, a connecting frame 7, a connecting rod 8, a threaded cylinder 10, a hollow connecting ring 14, and a suction pipe 15;

[0035] The feed pipe 4 is fixedly installed at the bottom of the fixative raw material tank 1, and the solenoid valve 5 is installed on the feed pipe 4. It should be noted that both the solenoid valve 5 and the liquid level sensor 16 are connected to an external PLC controller. When the liquid level sensor 16 detects that the liquid level is at the set value, the external PLC controller will close the solenoid valve 5.

[0036] The side plate 6 is fixedly installed on the outside of the feed tube 4, and the threaded cylinder 10 is threadedly installed on the outside of the feed tube 4. It should be noted that friction tape can be wrapped around the outside of the feed tube 4. After the threaded connection between the threaded cylinder 10 and the feed tube 4, the friction provided by the friction tape can ensure the stability of the threaded cylinder 10 when it rotates to a certain position.

[0037] The connecting frame 7 is fixedly connected to the threaded cylinder 10. An outer ring is fixedly installed on the connecting frame 7. The connecting rod 8 is vertically slidably installed on the side plate 6. Two baffles 9 are fixedly sleeved on the outside of the connecting rod 8. The bottom of the connecting rod 8 is fixedly connected to the hollow connecting ring 14. The suction pipe 15 is fixedly connected to the hollow connecting ring 14.

[0038] With the above structure, both the solenoid valve 5 and the liquid level sensor 16 are connected to an external PLC controller. When the liquid level sensor 16 detects that the liquid level is at the set value, the external PLC controller will close the solenoid valve 5. At this time, the feed pump 11 will be started to extract the excess liquid fixative raw material and introduce it into the fixative raw material tank 1. This allows for precise feeding and metering, ensuring the accuracy of the metering. Moreover, the metering value can be adjusted as needed. Rotating the threaded cylinder 10 causes it to rotate and move vertically, causing the outer ring to rotate and move vertically synchronously. The threaded cylinder 10 and the outer ring will drive the baffle 9 to move vertically, which in turn allows the connecting rod 8 to move the hollow connecting ring 14. This allows the height of the suction pipe 15 and the liquid level sensor 16 to be adjusted, facilitating the adjustment of the metering value as needed.

[0039] Specifically, the feeding and metering mechanism also includes a feed pump 11, a suction hose 12, a return pipe 13, and a liquid level sensor 16. The feed pump 11 is fixedly installed on the fixative raw material tank 1. The suction hose 12 and the return pipe 13 are both fixedly installed on the feed pump 11. The suction hose 12 is fixedly connected to the hollow connecting ring 14. The return pipe 13 is fixedly connected to the fixative raw material tank 1. The liquid level sensor 16 is fixedly installed at the bottom of the hollow connecting ring 14.

[0040] The above structure allows for the easy extraction of excess liquid fixative material and its introduction into the fixative material tank 1, thus enabling precise metering and ensuring accuracy.

[0041] Specifically, a base 2 is fixedly installed at the bottom of the fixative raw material tank 1, and a metering cylinder 3 is fixedly connected to the base 2. A discharge pipe 17 is fixedly installed at the bottom of the metering cylinder 3, and a discharge solenoid valve is installed on the discharge pipe 17. It should be noted that this facilitates the discharge of the metered fixative raw material.

[0042] Specifically, the connecting rod 8 contacts the threaded cylinder 10 and the outer ring, the bottom of the upper baffle 9 contacts the threaded cylinder 10 and the outer ring, and the top of the lower baffle 9 contacts the threaded cylinder 10 and the outer ring. It should be noted that when the threaded cylinder 10 is rotated, the baffle 9 can be moved vertically.

[0043] Specifically, a flow channel is provided on the hollow connecting ring 14, the suction hose 12 is connected to the flow channel, and the suction pipe 15 is connected to the flow channel. It should be noted that this facilitates the flow of liquid fixative raw materials.

[0044] Specifically, an addition tube is fixedly installed on the top of the fixative raw material tank 1, which facilitates the addition of liquid fixative raw material into the fixative raw material tank 1.

[0045] Working principle:

[0046] S1: Before feeding and metering, the metering value can be adjusted according to the amount of curing agent raw material required for production. By rotating the threaded cylinder 10, since the threaded cylinder 10 is installed on the outside of the feed pipe 4, it will move vertically while rotating, thereby driving the connecting frame 7 and the outer ring on the connecting frame 7 to move vertically in sync. The outer ring contacts the baffle 9 on the outside of the connecting rod 8, which will push the baffle 9 to drive the connecting rod 8 to slide vertically on the side plate 6. The hollow connecting ring 14 connected to the bottom of the connecting rod 8 moves accordingly, thereby adjusting the height of the suction pipe 15 and the liquid level sensor 16 to achieve the purpose of setting the target metering value. The friction tape wrapped around the outside of the feed pipe 4 can ensure that the threaded cylinder 10 is stable in the adjusted position.

[0047] S2: During the metering process, the liquid curing agent raw material in the fixative raw material tank 1 flows to the metering cylinder 3 through the feed pipe 4. At this time, the solenoid valve 5 is in the open state, and the liquid level sensor 16 monitors the liquid level in the metering cylinder 3 in real time and transmits the information to the external PLC controller. When the liquid level reaches the height set by the liquid level sensor 16, the PLC controller controls the solenoid valve 5 to close and stop feeding. If the solenoid valve 5 has a response time and causes too much feeding, exceeding the set liquid level, the material pump 11 is started. The material pump 11 extracts the excess material in the metering cylinder 3 through the suction hose 12, the flow channel on the hollow connecting ring 14 and the suction pipe 15, and then sends it back to the fixative raw material tank 1 through the return pipe 13 to ensure that the amount of raw material in the metering cylinder 3 accurately meets the set value.

[0048] S3: After metering is completed, open the discharge solenoid valve on the discharge pipe 17 at the bottom of the metering cylinder 3. The metered curing agent raw material is discharged through the discharge pipe 17 and enters the next production stage. When the raw material in the curing agent raw material tank 1 is insufficient, the raw material can be supplemented through the top addition pipe. The whole process realizes accurate metering and feeding of curing agent raw material, effectively solving the metering error problem caused by the response time of the solenoid valve in the existing technology.

[0049] The above provides a detailed description of the feeding and metering device for curing agent production provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
