Description

Technical Field

[0001] This utility model relates to the field of adhesive production, specifically to an adhesive mixing and anti-curing device. Background Technology

[0002] Adhesive is a liquid or semi-liquid substance used to bond materials, firmly joining different objects through chemical or physical actions. Its main components include base materials (such as synthetic resins and rubber), solvents, plasticizers, and curing agents. Its bonding principles include mechanical interlocking, molecular diffusion, or chemical bonding. When using it, the surface must be cleaned, the adhesive applied evenly, and appropriate pressure applied. Some adhesives require curing time. Advantages include uniform stress distribution at the joint and the ability to bond dissimilar materials, but durability or environmental issues may exist. It is widely used in packaging, construction, electronics, medical, and other fields, and is an indispensable adhesive material in modern production and life. Adhesive production requires stirring using mixing equipment.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of an adhesive mixing and anti-curing device, comprising a mixing tank 1, with a funnel-shaped bottom 102 at the lower end of the mixing tank 1. Four connecting pipes 5 are fixedly connected in a ring array to the lower end face of the funnel-shaped bottom 102. The upper ends of the connecting pipes 5 extend into the interior of the funnel-shaped bottom 102, and electric heating rods 6 are inserted into the interior of each connecting pipe 5. The upper ends of the electric heating rods 6 pass through the connecting pipes 5 and extend into the interior of the funnel-shaped bottom 102. A sealing ring 501 is provided between the upper end of the connecting pipe 5 and the electric heating rod 6. The lower end of the electric heating rod 6 extends out of the lower end of the connecting pipe 5 and is fixedly connected to a connecting ring 601. The connecting ring 601 is fixedly connected to the lower end of the connecting pipe 5 by multiple screws 602. When the adhesive raw material is mixed inside the mixing tank 1, the four electric heating rods 6 provide constant temperature heating to the adhesive raw material to prevent premature curing during mixing.

[0024] Please see Figure 2 and Figure 3 A limiting tube 105 is fixedly connected to the middle of the upper end of the mixing tank 1. A rotating tube 2 is rotatably connected to the lower end of the limiting tube 105. A stirring rod 201 is fixedly connected to both the upper and lower ends of the rotating tube 2. A scraper 202 is fixedly connected to the ends of the two stirring rods 201 on both sides of the rotating tube 2 away from the rotating tube 2. A rotating shaft 3 is rotatably connected inside the rotating tube 2. The lower end of the rotating shaft 3 extends out of the lower end of the rotating tube 2 and is fixedly connected to a spiral blade 301 inside the funnel-shaped bottom 102. The rotation of the rotating tube 2 drives the stirring rods 201 and the scraper 202 to rotate synchronously, so that the stirring rods 201 stir the glue material inside the mixing tank 1. At the same time, when the scraper 202 rotates, it scrapes the inner wall of the mixing tank 1 to prevent the glue material from sticking and causing uneven mixing. The rotating shaft 3 drives the spiral blade 301 to rotate, which conveys the glue material in the funnel-shaped bottom 102 upward, so that the glue material flows inside the mixing tank 1 and improves the uniformity of mixing.

[0025] Please see Figure 2 A feed inlet 101 is fixedly provided on one side of the middle of the upper end face of the mixing tank 1, and a discharge port 103 is fixedly connected to the middle of the lower end of the funnel-shaped bottom 102. A control valve 104 is fixedly connected to the discharge port 103. The glue raw material is added into the mixing tank 1 through the feed inlet 101. After the glue raw material is mixed, the control valve 104 is opened and the glue is discharged through the discharge port 103.

[0026] Please see Figure 2 A drive box 4 is fixedly connected to the upper end of the mixing tank 1. A drive motor 401 is fixedly installed inside the drive box 4. A third bevel gear 40 is fixedly connected to the output shaft of the drive motor 401. The upper end of the rotating tube 2 extends through the interior of the limiting tube 105 into the interior of the drive box 4 and is fixedly connected to a first bevel gear 203. The upper end of the rotating shaft 3 extends out of the upper end of the rotating tube 2 and is fixedly connected to a second bevel gear 302. The upper and lower ends of the third bevel gear 402 are respectively meshed with the teeth of the first bevel gear 203 and the second bevel gear 302. The drive motor 401 drives the rotating tube 2 and the rotating shaft 3 to rotate synchronously and coaxially in reverse.

[0027] Working Principle: In operation, the adhesive material is first added to the mixing tank 1 through the feed inlet 101. The drive motor 401 is then started, driving the third bevel gear 402 to rotate. Through gear meshing, the first bevel gear 203 and the second bevel gear 302 rotate in opposite directions, thus achieving coaxial and counter-rotating rotation of the rotating tube 2 and the rotating shaft 3. The rotating tube 2 drives the stirring rod 201 and scraper 202 to stir the adhesive material while simultaneously scraping away any adhering material from the inner wall. The rotating shaft 3 drives the spiral blades 301 to push the adhesive from the bottom upwards, creating a circulating flow. During this process, four electric heating rods 6 continuously heat the adhesive in the funnel-shaped bottom 102 at a constant temperature to prevent premature curing of the material during stirring. After stirring is complete, the control valve 104 is opened to discharge the finished adhesive through the discharge port 103.

[0028] 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. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
