Description

Technical Field

[0001] This utility model relates to the technical field of laboratory liquid control equipment, and in particular to a pressure-stabilized dripping device for water-based adhesive solutions. Background Technology

[0002] Water-based adhesive solutions are polymeric materials that use water as a solvent or dispersion medium. They are commonly used in bonding, coating, and sealing processes, offering advantages such as being environmentally friendly, non-toxic, and easy to clean. They are widely used in packaging, electronics, pharmaceuticals, and building materials industries. To ensure effective coating or bonding, water-based adhesive solutions must be applied to the substrate surface in a stable and controllable manner. Issues such as flow control, pressure stability, and preventing air bubble formation during the application process directly affect the final product's bond strength and appearance quality. Therefore, pressure-stabilizing dispensing devices are typically used in relevant production processes to achieve uniform output of the water-based adhesive solution, meeting the needs of precision machining or automated production lines.

[0003] Existing pressure-stabilized dripping devices for water-based adhesive solutions typically connect a storage tank to a tippet, using air pressure, gravity, or pump pressure to stably drip the solution from the dropper. They utilize regulating valves, buffer chambers, and other structures to control the dripping speed and pressure stability, achieving a uniform and continuous dripping process. However, adjusting the tippet height often requires replacing or disassembling support components to accommodate different container sizes, which is not only cumbersome and inefficient but also unsuitable for use in experimental or production environments with multiple container sizes or frequent container changes. Therefore, this paper proposes a pressure-stabilized dripping device for water-based adhesive solutions to address these issues. Summary of the Invention

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a water-based adhesive solution pressure-stabilized dripping device, comprising a base plate 1, a storage bottle 6, and a titrator 7. The titrator 7 is used to achieve stable and controllable dripping of the water-based adhesive solution in experimental or industrial applications, effectively improving the accuracy and repeatability of titration. An adjustment mechanism is provided on the top of the base plate 1 to flexibly adjust the height of the storage bottle 6 to adapt to different titration needs. The storage bottle 6 is connected to the base plate 1 through the adjustment mechanism to ensure the device is stable and secure during use, preventing liquid spillage or device tilting. A fixing mechanism is provided on the top of the base plate 1 to stabilize the position of the measuring cup and prevent it from shifting due to vibration or misoperation. The titrator 7 is installed on the top of the storage bottle 6, directly connected to the bottle mouth, and is used to control the flow rate of the water-based adhesive solution. Its placement on top of the fixing mechanism ensures that the titrator 7 is vertically downward during operation, facilitating precise dripping. The control and titrator 7 are located on the top of the fixed mechanism; the adjustment mechanism includes a sleeve 2 and a slide bar 3. The sleeve 2 is fixedly connected to the top of the base plate 1, and the side wall of the slide bar 3 is slidably connected to the inside of the sleeve 2. The sleeve 2 serves as a support and guide. A connecting arm 5 is fixedly connected to the side wall of the slide bar 3. A liquid storage bottle 6 is located inside the connecting arm 5. The connecting arm 5 is used to support the liquid storage bottle 6. The liquid storage bottle 6 is nested inside the connecting arm 5. A groove 4 is located inside the sleeve 2 to limit the rotation of the slide bar 3 and guide its linear movement. A screw 8 is threaded inside the slide bar 3. A knob 9 is fixedly connected to the side wall of the screw 8. The user can finely adjust the liquid level by rotating the knob 9 to achieve drip rate control. A squeezing pad 10 is provided on the outside of the screw 8. The screw 8 is located inside the groove 4. The squeezing pad 10 fits against the side wall of the sleeve 2. The squeezing pad 10 is made of flexible material so that it can deform under pressure.

[0032] Reference Figures 4-5 The fixing mechanism includes a placement plate 12 and a clamping block 13. A fixing seat 11 is fixedly connected to the top of the base plate 1, providing sturdy support for the entire structure. The placement plate 12 is fixedly connected to the top of the fixing seat 11 to support the measuring cup. The side wall of the clamping block 13 is slidably connected to the inside of the placement plate 12, and can automatically adjust the clamping position according to the outer size of the measuring cup to achieve adaptation and fixing of different types of measuring cups. The fixing seat 11 has a cavity inside, and a motor 15 is installed inside the cavity. A turntable 16 is fixedly connected to the output end of the motor 15. A curved plate 17 is rotatably connected to the top of the turntable 16. These curved plates 17... The 7 are evenly distributed symmetrically to provide stable and balanced torque transmission during rotation. One side of the bent plate 17 is rotatably connected to the hinge frame 18. The side wall of the hinge frame 18 is fixedly connected to the side wall of the clamping block 13. The side wall of the clamping block 13 is slidably connected to the inside of the fixed seat 11. The turntable 16 is driven to rotate by the starting motor 15, and then the clamping block 13 is synchronously slid through the bent plate 17 to achieve the action of clamping or releasing the measuring cup. Rubber pads 14 are fixedly connected to the inner side of the clamping block 13. Multiple bent plates 17 are provided and are arranged symmetrically. The titrator 7 is located at the top center of the placement plate 12.

[0033] Working principle: When using this device, first place the measuring cup on the top of the placement plate 12, then start the motor 15 to drive the turntable 16 to rotate, and drive the bending plate 17 to move, so that one side of it moves with the rotation of the turntable 16, while the other side deflects inside the hinge frame 18, and simultaneously drives the clamping block 13 to move. At this time, the clamping block 13 moves inward inside the placement plate 12, thereby clamping and fixing the measuring cup. At this time, the dropper 7 can be controlled to achieve the effect of stable dripping of water-based adhesive solution as needed.

[0034] While using the tippet 7, its height can be adjusted according to the height of the measuring cup. By twisting the knob 9, the screw 8 moves from the inside of the slide bar 3 to the outside, releasing the pressure on the pressure pad 10. Then, by pulling the slide bar 3 upward, it slides inside the sleeve 2 to change the height of the tippet 7. After the height is determined, the knob 9 is twisted in the opposite direction to twist the screw 8 back into the slide bar 3, re-pressing the pressure pad 10 so that it fits tightly against the outside of the slide bar 3 and deforms. The position of the tippet 7 is fixed by the friction between the pressure pad 10 and the slide bar 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
