Description

Technical Field

[0001] This utility model relates to a flow control device, and more particularly to a closed-loop control device for the flow of auxiliary agent solution in the preparation process of water-based adhesives. Background Technology

[0002] Currently, the flow rate of additives added during the preparation of water-based adhesives depends entirely on the operator's subjectivity. Personnel directly add the additives to the adhesive container, making it impossible to standardize the solvent addition rate. This results in poor adhesive uniformity, poor batch stability, and frequent quality problems such as adhesive layering and abnormal curing. Furthermore, when adding large quantities of additives, spillage is easily caused by manual addition. Inconsistent addition rates during manual addition mean that the additives are not fully integrated with the semi-finished adhesive during mixing, leading to abnormal performance during use and causing problems such as filter clogging, insufficient adhesive in the product, and abnormal curing. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model discloses a closed-loop control device for the flow rate of additive solution in the water-based adhesive preparation process. This device solves the problem that the existing additive solution addition method lacks sufficient flow rate control precision, resulting in poor adhesive uniformity, poor batch stability, and frequent quality problems such as colloid stratification and abnormal curing.

[0004] The technical solution of this utility model is as follows:

[0005] A closed-loop control device for the flow rate of an additive solution in the preparation process of a water-based adhesive includes a storage container, a power valve, and a flow meter. The bottom of the storage container is provided with a discharge port, which is connected to an adhesive hose through the power valve. The adhesive hose is equipped with a flow meter, and the storage container is provided with a compressed air inlet.

[0006] As a further improvement of this utility model, the storage container is provided with a connector that engages with the edge of the glue can. This technical solution, compared to the original snap-fit ​​structure on the edge of the glue can, allows for quick disassembly and installation of the storage container and the glue can, making it more convenient to use.

[0007] As a further improvement of this utility model, the power valve is an electric / pneumatic programmable power valve. This technical solution provides precise and convenient control.

[0008] As a further improvement of this utility model, the flow meter is an ultrasonic flow meter. This technical solution allows for real-time monitoring of the flow rate and velocity within the hose; moreover, the ultrasonic flow meter employs non-contact ultrasonic detection technology, avoiding the risk of solvent contamination.

[0009] As a further improvement to this invention, the hose is made of transparent polyurethane. This technical solution offers resistance to chemical corrosion, anti-swelling properties, and meets the requirements for visual management.

[0010] As a further improvement of this utility model, the closed-loop control device for the flow rate of the auxiliary agent solution in the water-based adhesive preparation process includes a controller. The controller is electrically connected to a flow meter and a power valve, and dynamically adjusts the opening degree of the power valve based on feedback from the flow meter. Using this technical solution, the valve opening can be dynamically adjusted by comparing real-time flow meter data with preset parameters.

[0011] As a further improvement of this utility model, the closed-loop control device for the flow rate of the auxiliary agent solution in the water-based adhesive preparation process includes a display screen, which is electrically connected to the controller. This technical solution allows for the simultaneous display of flow curves and control parameters. Furthermore, the display screen is a touchscreen, enabling human-machine interaction.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By adopting the technical solution of this utility model, the precise quantitative addition of the additive solution is achieved through closed-loop flow control, ensuring uniform fusion of the adhesive components and achieving standardized operation; the existing equipment structure is reused to the greatest extent, and the cost of a single set of modification is reduced by 78% compared to replacing the entire system, achieving lightweight modification; the frequency of operator intervention is reduced by 90%, and there are no special requirements for site layout, thus improving human efficiency.

[0017] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a closed-loop control device for the flow rate of an auxiliary agent solution in the preparation process of water-based adhesive includes a storage container 1, a power valve 2, a flow meter 4, a controller, and a display screen. The bottom of the storage container 1 is provided with a discharge port, which is connected to an adhesive hose 3 through the power valve 2. The adhesive hose 3 is provided with a flow meter 4. The storage container 1 is provided with a compressed air inlet 6, which is connected to a compressed air pipe 5.

[0019] The storage container 1 is provided with a connector 7 that engages with the edge of the glue container 8. The glue container 8 is a container for preparing water-based glue.

[0020] The power valve 2 is an electric / pneumatic programmable power valve 2. The flow meter 4 is an ultrasonic flow meter 4. The hose 3 is made of transparent polyurethane material.

[0021] The controller is electrically connected to the flow meter 4, the power valve 2, and the display screen. Based on the feedback from the flow meter 4, it dynamically adjusts the opening of the power valve 2. The valve opening can be dynamically adjusted by comparing the real-time data from the flow meter 4 with preset parameters. The display screen can simultaneously display the flow curve and control parameters.

[0022] The technical solution of this embodiment places the additive solution in a storage container and controls the flow rate through a flow meter and a power valve. This avoids the abnormal glue-forming performance caused by uneven addition of the additive solution during the water-based glue preparation process, and facilitates standardized operation. It maximizes the reuse of existing equipment structure, reduces the cost of a single set of modifications by 78% compared to replacing the entire system, reduces the frequency of operator intervention by 90%, and has no special requirements for site layout.
