Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to an anti-caking mixing device for glass glue production. Background Technology

[0002] Glass sealant is a material used to bond and seal various types of glass to other substrates. It is mainly divided into two categories: silicone sealant and polyurethane (PU) sealant. Silicone sealant is what we commonly refer to as glass sealant. During production, glass sealant requires mixing equipment to prevent it from solidifying.

[0003] Existing anti-caking mixing equipment for glass sealant production uses a single-shaft mixing method, such as Chinese patent with authorization announcement number CN217855717U. The single-shaft mixing method makes the mixing process simple and makes it difficult to improve the mixing efficiency. Utility Model Content

[0014] As a further embodiment of this utility model: the moving component also includes a top plate and a plurality of electric push rods, the other ends of the plurality of cylindrical rods are fixed to the top plate, and the two ends of the electric push rods are respectively fixed to the top plate and the moving plate.

[0015] As a further embodiment of this utility model: the rotating assembly includes a recessed frame and a servo motor. Both ends of the recessed frame are fixed to the moving plate, the servo motor is fixed to the recessed frame, and the output shaft of the servo motor is coaxially fixed to the square rod.

[0016] As a further embodiment of this utility model: a limiting ring is fixed on the outer side of the top end of the square rod and is coaxially arranged therewith.

[0019] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0020] This invention enables the stirring shaft to reciprocate up and down, thereby achieving vertical stirring. Simultaneously, during the rotation and linear reciprocating motion of the stirring shaft, the stirring plate continuously expands and contracts. This reciprocating expansion and contraction motion, superimposed on the rotational motion of the stirring shaft, can increase the shear rate and turbulence intensity of the fluid. The periodic expansion and contraction alters the flow field structure, potentially breaking the laminar boundary layer, promoting micro-mixing, and generating unsteady flow, inducing secondary flow or vortices, expanding the stirring range, reducing mixing dead zones, thereby improving stirring efficiency and anti-condensation effect.

[0027] 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.

[0028] Please see Figures 1-5 In this embodiment of the present invention, an anti-caking stirring device for producing glass glue includes a base plate 1 and a movable plate 3 disposed above the base plate 1. A movable component is disposed on the outer side of the base plate 1 to enable the movable plate 3 to move vertically.

[0029] A sliding hole with a vertically oriented central axis is provided at the middle position of the outer side of the movable plate 3;

[0030] The interior of the sliding hole is equipped with a hollow stirring shaft 9;

[0031] A square rod 14, coaxially arranged with the top of the stirring shaft 9, is slidably inserted into it;

[0032] A rotating assembly for rotating the square rod 14 is provided on the outer side of the movable plate 3;

[0033] Rollers 12 are rotatably mounted on both sides of the top end of the stirring shaft 9;

[0034] Two arc-shaped plates 11, which are coaxial with the stirring shaft 9, are fixed on the outer side of the movable plate 3. The two arc-shaped plates 11 are located on both sides of the stirring shaft 9, and the top of the arc-shaped plates 11 protrudes upward to form an arch.

[0035] Based on the above connection relationship, the present invention is as follows: The servo motor 7 is started, and the servo motor 7 causes the square rod 14 to rotate through the output shaft. The square rod 14 drives the stirring shaft 9 to rotate. The stirring blade 10 at the bottom of the stirring shaft 9 stirs the glass glue in the stirring tank. When the stirring shaft 9 is stirring, when the roller 12 on the stirring shaft 9 passes the arc plate 11, the stirring shaft 9 moves upward along the square rod 14, and the return spring 13 is compressed. When it has completely passed the arc plate 11, the stirring shaft 9 returns to its original position. Thus, it can be seen that the stirring shaft 9 can stir in the vertical direction.

[0036] Specifically, the moving component includes a guide structure, which includes multiple cylindrical rods 2. One end of each cylindrical rod 2 is fixed to the base plate 1, and the moving plate 3 is slidably sleeved on each cylindrical rod 2. The guide structure is designed so that the moving plate 3 can only move vertically relative to the base plate 1.

[0037] Specifically, the moving assembly also includes a top plate 5 and multiple electric push rods 4. The other ends of the multiple cylindrical rods 2 are fixed to the top plate 5, and the two ends of the electric push rods 4 are fixed to the top plate 5 and the moving plate 3, respectively. A circular groove, coaxially arranged with the stirring shaft 9, is opened on the top of the bottom plate 1. A mixing tank containing silicone sealant is placed in the circular groove, the outer diameter of which matches the inner diameter of the groove. The electric push rods 4 extend, causing the moving plate 3 to move downwards along the cylindrical rods 2 until the stirring shaft 9 on the moving plate 3 enters the mixing tank. The result is as follows: Figure 2 As shown.

[0038] Specifically, the rotating assembly includes a recessed frame 6 and a servo motor 7. Both ends of the recessed frame 6 are fixed on the moving plate 3. The servo motor 7 is fixed to the recessed frame 6. The output shaft of the servo motor 7 is coaxially fixed with the square rod 14. When the servo motor 7 is started, the servo motor 7 causes the square rod 14 to rotate through the output shaft. The square rod 14 drives the stirring shaft 9 to rotate.

[0039] Specifically, a limiting ring 8 is fixed to the outer side of the top end of the square rod 14 and is coaxially arranged therewith. A return spring 13 is sleeved on the outer side of the square rod 14. The two ends of the return spring 13 are in contact with the bottom of the limiting ring 8 and the top end of the stirring shaft 9, respectively, and the return spring 13 is kept in a compressed state. The return spring 13 applies a pushing force to the top of the stirring shaft 9, so that the stirring shaft 9 is always subjected to a downward force, thereby ensuring that the roller 12 of the stirring shaft 9 is always in contact with the arc plate 11 or the moving plate 3 during the rotation of the stirring shaft 9.

[0040] Specifically, a plurality of stirring blades 10 are arranged in a ring at equal intervals and arranged laterally on the outer side of the bottom end of the stirring shaft 9. The stirring blades 10 are composed of a square tube 16 and a square plate 17 slidably inserted into the square tube 16. One end of the square tube 16 is fixed and connected to the stirring shaft 9. One end of the square plate 17 is rotatably mounted with a connecting rod 15 together with the bottom end of the square rod 14. When the stirring shaft 9 moves upward along the square rod 14, the bottom end of the square rod 14 pushes out the square plate 17 in the stirring blades 10 through the connecting rod 15, thereby extending the stirring blades 10 as a whole. When the stirring shaft 9 returns to its original position, the square plate 17 in the stirring blades 10 is pulled back.

[0041] Working principle:

[0042] Place the mixing bowl containing the silicone sealant into the round hole groove, with the outer diameter of the mixing bowl matching the inner diameter of the round hole groove.

[0043] The electric push rod 4 extends, causing the moving plate 3 to move downwards along the cylindrical rod 2 until the stirring shaft 9 on the moving plate 3 enters the mixing tank. The result is as follows: Figure 2 As shown;

[0044] Start the servo motor 7. The servo motor 7 causes the square rod 14 to rotate through the output shaft. The square rod 14 drives the stirring shaft 9 to rotate. The stirring blade 10 at the bottom of the stirring shaft 9 stirs the glass glue in the stirring tank.

[0045] When the stirring shaft 9 is stirring, as the roller 12 on the stirring shaft 9 passes the arc plate 11, the stirring shaft 9 moves upward along the square rod 14, the return spring 13 is compressed, and the bottom end of the square rod 14 pushes out the square plate 17 inside the stirring blade 10 through the connecting rod 15, thereby causing the stirring blade 10 to extend as a whole. When the stirring shaft 9 returns to its original position, the square plate 17 inside the stirring blade 10 is pulled back. It can be seen that during the rotation and reciprocating linear motion of the stirring shaft 9, the stirring plate is constantly undergoing expansion and contraction. This reciprocating expansion and contraction motion superimposed on the rotational motion of the stirring shaft 9 can increase the shear rate and turbulence intensity of the fluid. The periodic expansion and contraction changes the flow field structure, which may break the laminar boundary layer, promote micro-mixing, and generate unsteady flow, triggering secondary flow or vortices, expanding the stirring range, reducing the mixing dead zone, thereby improving the stirring efficiency and the anti-condensation effect.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
