In particular, for some sensitive adhesive systems, high shear forces may cause irreversible structural damage.

[0023] Example

[0024] Reference Figure 1-3 , a device for improving the viscosity stability of glue liquid, comprising a stirring tank 1, the upper end of the stirring tank 1 is connected with a mounting plate by bolts, the upper side wall of the mounting plate is fixedly connected with a mounting frame 3, a driving mechanism and a controller 5 are arranged above the mounting frame 3, the driving mechanism comprises a motor 2 and a reduction box 4, the motor 2 is located directly above the reduction box 4 and is fixedly connected to the upper side wall thereof, the output shaft of the motor 2 extends to the inside of the reduction box 4 and is arranged with gear meshing therewith, a stirring shaft 6 is fixedly connected to the lower side wall of the gear connected to the output shaft of the motor 2, the end of the stirring shaft 6 passes through the mounting frame 3 and the mounting plate and extends to the inside of the stirring tank 1, and an adaptive stirring device is fixedly installed on the stirring shaft 6;

[0025] It should be noted that: the two ends of the mounting plate are hingedly connected with movable doors 101 for feeding the raw materials and solvents required for preparing the glue solution. The lower end of the movable door 101 is sealed with the outlet of the mixing tank 1 to ensure the purity of the glue solution during preparation. The lower end of the mixing tank 1 is penetrated with a discharge valve 102. The controller 5 is electrically connected with the discharge valve 102 and the motor 2 and the reduction box 4. The working state of the discharge valve 102, the motor 2 and the reduction box 4 can be controlled by the controller 5.

[0026] Reference Figure 3-5 The adaptive stirring device includes a mounting sleeve 7 fixedly mounted on the stirring shaft 6, a plurality of stirring rods 8 are fixedly connected to the outer side of the mounting sleeve 7, a movable sleeve 9 is slidably sleeved on the far end of the stirring rod 8, a plurality of groups of levers 901 are fixedly connected to the outer side of the movable sleeve 9, and a limiting ring 801 is fixedly connected to the end of the stirring rod 8 to prevent the movable sleeve 9 from being separated from the stirring rod 8. The end of the stirring rod 8 away from the mounting sleeve 7 is elastically connected to the bottom wall of the inner cavity of the movable sleeve 9 by a connecting spring 902. The plurality of groups of levers 901 are distributed in an annular manner and equidistantly along the central axis of the mounting sleeve 7 to further disturb the mixed liquid in the stirring tank 1. The limiting ring 801 is slidably connected to the inner cavity of the movable sleeve 9, and the stirring rod 8 is slidably sealed to the bottom outlet of the movable sleeve 9, thereby ensuring that the glue does not enter the movable sleeve 9.

[0027] It should be noted that the length of the movable sleeve 9 is smaller than the length of the stirring rod 8, which ensures that the movable sleeve 9 can move flexibly on the stirring rod 8. The sum of the lengths of the movable sleeve 9 and the stirring rod 8 is smaller than the inner cavity radius of the stirring tank 1, ensuring that the inner wall of the stirring tank 1 will not be scratched when the equipment is running.

[0028] The working principle of the device for improving the viscosity stability of the glue liquid is as follows: according to the required formula and proportion, the required materials and additives, such as resin, solvent, hardener, filler, etc., are prepared, and various components are added into the stirring tank 1 in sequence through the movable doors 101 connected by hinges at both ends of the stirring tank 1 according to the formula and proportion, while the tank can be kept in a sealed state, and the motor 2 is started. Driven by the motor 2 and the reduction box 4, the stirring shaft 6 starts to rotate, and accordingly, the adaptive stirring device starts to rotate, so that the components in the glue liquid can be fully mixed, and the stirring time and speed can be adjusted by the controller 5 according to the specific materials and formula to ensure uniform mixing;

[0029] In this process, the rotation speed of the stirring shaft 6 directly affects the displacement of the movable sleeve 9, because the stirring rod 8 fixed on the shaft will generate centrifugal force when rotating, and this centrifugal force will act on the elastic force generated by the connecting spring 902 connected between the stirring rod 8 and the movable sleeve 9. When the rotation speed increases, the centrifugal force will also increase, causing the movable sleeve 9 to move outward along the stirring rod 8 and stretch the spring. This design allows the movable sleeve 9 to adaptively adjust its position on the stirring rod 8 according to the rotation speed of the stirring shaft 6;

[0030] By changing the rotation speed of the stirring shaft 6, the moving distance of the movable sleeve 9 along the stirring rod 8 can be controlled, so as to achieve the purpose of effectively mixing the glue in different areas of the stirring tank 1. This adaptive mechanism enables the stirring system to be flexibly adjusted according to the characteristics of the glue and process requirements to achieve the best mixing effect;

[0031] When the stirring rod 8 rotates, the pressure of the glue on the lever 901 causes the movable sleeve 9 to rotate relative to the stirring rod 8. This rotation has two main effects:

[0032] Area diffusion: When the lever 901 rotates, the tangential force acting on the glue liquid will move the glue liquid, increase the mixing area, help break the bubbles, and thus improve the mixing efficiency;

[0033] Stirring speed adjustment: The rotation of the movable sleeve 9 plays a decelerating role to prevent the stirring rod 8 from rotating too fast, which is extremely important for maintaining the viscosity stability of the glue and avoiding the introduction of too many air bubbles;

[0034] Through this innovative design, the stirring system can not only mix the glue more evenly, but also avoid adverse high shear forces on the glue by controlling the rotation speed and the movement of the movable sleeve 9, thereby ensuring the stability and quality of the final product. In summary, this stirring equipment can achieve adaptive control of the glue mixing process through an intelligent adjustment mechanism, thereby improving the uniformity of the glue and the viscosity stability of the production process.
