Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, specifically to a stirring device for adhesive production with defoaming function. Background Technology

[0002] Adhesive, as an intermediate material for connecting two materials, belongs to the category of fine chemical products. It comes in many varieties and can be classified according to the adhesive, physical form, hardening method, and the material of the adhered objects. In the production process of adhesive, stirring is a crucial step. During the preparation of the mixture, stirring is required to ensure thorough mixing in order to enhance the adhesive's bonding quality.

[0003] In current adhesive production mixing equipment, air can easily enter the adhesive during processing. This results in voids within the cured adhesive, reducing the actual contact area at the bonding interface and causing uneven stress distribution. Under stress, stress tends to concentrate around these voids, creating stress concentration points at the bonding points. This reduces the bond strength between the adhesive and the adherend, preventing the adhesive from fully exerting its adhesive properties and leading to bonding failure. Furthermore, air ingress into the adhesive results in inconsistent quality, making it difficult to guarantee product consistency and stability, and increasing the scrap and defect rates during production.

[0022] 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.

[0023] Please see Figure 1-5 As shown, a mixing device for glue production with defoaming function includes a base plate 1, a mixing tank 2 placed on the right side of the top of the base plate 1, a motor 3 fixed in the middle of the top of the mixing tank 2, and the output shaft of the motor 3 extending into the interior of the mixing tank 2. A stirring paddle 4 is fixed at the bottom end of the output shaft of the motor 3. Mounting brackets 5 are bolted to the left and right sides of the top of the mixing tank 2. A lifting structure 6 is provided inside the mounting bracket 5. An ultrasonic defoaming rod 7 is provided on the front side of the lifting structure 6. Fixing holes 8 are provided on the left and right sides of the top of the mixing tank 2, and the ultrasonic defoaming rod 7 extends into the interior of the mixing tank 2 through the fixing holes 8. A water tank 9 is fixed to the left side of the top of the base plate 1, and a temperature control structure 10 is fixed to the top of the water tank 9. A mounting shell 11 is fitted on the surface of the mixing tank 2. The interior of the mounting shell 11 is hollow, and the mounting shell 11 is fixedly connected to the mixing tank 2.

[0024] The lifting structure 6 includes a lead screw 61, a drive motor 62, a lifting block 63, and a mounting plate 64. The lead screw 61 is rotatably connected inside the mounting frame 5. The drive motor 62 is fixed to the top of the mounting frame 5, and the output shaft of the drive motor 62 passes through the mounting frame 5 and is fixedly connected to the top end of the lead screw 61. The lifting block 63 is threadedly connected to the surface above the lead screw 61. The mounting plate 64 is fixed to the front side of the lifting block 63, and the top of the ultrasonic defoaming rod 7 is fixedly connected to the bottom of the mounting plate 64. A limit groove 12 is opened on the rear side of the inner wall of the mounting frame 5, and a limit block 13 is fixed to the back of the lifting block 63. The ultrasonic defoaming rod 7 is located inside the limiting groove 12 and is slidably connected to the inner wall of the limiting groove 12. When the ultrasonic defoaming rod 7 is opened, the drive motor 62 above is also turned on, which causes the output shaft of the drive motor 62 to drive the lead screw 61 to rotate. The lifting block 63 moves on the surface of the lead screw 61. At this time, the limiting block 13 slides inside the limiting groove 12 to limit the lifting block 63, so that the mounting plate 64 stably drives the ultrasonic defoaming rod 7 to move up and down. This allows the ultrasonic waves to act at different depths and positions in the glue, more comprehensively covering the air bubbles in the glue, increasing the chance of air bubbles contacting the ultrasonic waves, and thus improving the defoaming effect.

[0025] A cleaning ring 14 is bonded to the inner wall of the fixing hole 8, and the inner wall surface of the cleaning ring 14 is attached to the surface of the ultrasonic defoaming rod 7 and slidably connected to the surface of the ultrasonic defoaming rod 7. When the ultrasonic defoaming rod 7 moves up and down, the adhesive on the surface of the ultrasonic defoaming rod 7 can be scraped off through the cleaning ring 14 to clean the ultrasonic defoaming rod 7.

[0026] The agitator 4 is a screw agitator. The blade shape of the agitator 4 is relatively smooth, and the shearing effect on the liquid during the agitation process is relatively small, making it less likely to introduce a large amount of air.

[0027] The temperature control structure 10 includes a heating rod 101, a thermostat 102, a first water pump 103, a second water pump 104, and a water pipe 105. The heating rod 101 is fixed to the left and right sides of the top of the water tank 9, and the bottom of the heating rod 101 penetrates the water tank 9 and extends into the interior of the water tank 9. The thermostat 102 is fixed to the front side of the top of the water tank 9, and the thermostat 102 is electrically connected to the heating rod 101. The first water pump 103 and the second water pump 104 are fixed to the right side of the top of the water tank 9, and both the first water pump 103 and the second water pump 104 are connected to the water tank 9. The water pipe 105 connects to the top of the first water pump 103 and the second water pump 104, and... The other end of the water pipe 105 is connected to the mounting shell 11. Before the glue needs to be mixed, the operator can turn on the heating rod 101 and control the heating rod 101 stably through the temperature controller 102. After the water temperature inside the water tank 9 is raised to a suitable temperature, the first water pump 103 pumps the water inside the water tank 9 into the interior of the mounting shell 11 through the water pipe 105, while the second water pump 104 pumps the water inside the mounting shell 11 back into the water tank 9 through the water pipe 105, realizing water circulation. This allows the mounting shell 11 to control the temperature inside the mixing tank 2, so that the glue inside the mixing tank 2 can be mixed at a suitable temperature, thereby improving the glue processing quality.

[0028] The outer surface of the mounting shell 11 is coated with an insulating coating, which is an aerogel insulating coating. The insulating coating can insulate the mounting shell 11 and the interior of the mixing tank 2, preventing the external temperature from affecting the glue mixing operation inside the mixing tank 2.

[0029] Working Principle: When the adhesive needs to be stirred, the mixing tank 2 is used to hold the adhesive raw materials. The motor 3 is fixed to the top of the mixing tank 2, and its output shaft drives the stirring paddle 4, which extends into the tank, to rotate. The stirring paddle 4 adopts a screw design, and its smooth blade shape can effectively reduce the shear force on the adhesive during the stirring process, thereby reducing air mixing. While the stirring paddle 4 is stirring the adhesive inside the mixing tank 2, the heating rod 101 heats the water in the water tank 9 under the control of the temperature controller 102. The first water pump 103 pumps the heated water into the hollow jacket of the mounting shell 11 through the water pipe 105. The second water pump 104 simultaneously pumps the water in the jacket back to the water tank 9, forming a closed loop circulation. This circulation channel ensures that the constant temperature water surrounds the mixing tank 2, ensuring... The adhesive is stirred at the optimal temperature. The aerogel insulation coating on the outer wall of the mounting shell 11 greatly reduces heat loss and ensures temperature stability. After stirring, when the drive motor 62 drives the lead screw 61 to rotate, the lifting block 63 achieves precise lifting under the sliding fit constraint of the limit block 13 and the upper limit groove 12 of the mounting frame 5. This drives the ultrasonic defoaming rod 7 at the front end of the mounting plate 64 to move vertically along the fixing hole 8. After the ultrasonic defoaming rod 7 is activated, its high-frequency vibration generates a cavitation effect inside the adhesive, causing the bubbles to collapse and merge. At the same time, the lifting motion allows the ultrasonic energy to cover different depths and areas, significantly improving the uniformity and efficiency of defoaming. Then, the staff can take out the defoamed adhesive and complete the processing of the adhesive.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
