Technical Field
[0001] This utility model relates to the field of adhesive mixing technology, specifically to an adhesive mixing device for adhesive tape production. Background Technology
[0002] Adhesive tape consists of a substrate, adhesive, and release paper. It achieves bonding through the adhesive. According to the substrate, it can be divided into cloth-based, paper-based, etc.; according to the adhesive type, it can be divided into acrylic, rubber, etc. It has functions such as adhesion, fixation, and sealing, and is widely used in packaging, electronics, medical and other fields. The selection of the type needs to consider the substrate, the application scenario and performance requirements. The adhesive is the substance that gives the adhesive tape its adhesive ability. During the production process, mixing equipment is required to stir and mix the adhesive.
[0003] In reality, adhesives are quite viscous. To achieve thorough mixing, the mixing structure typically requires a high mixing speed and multiple layers of mixing rods or blades. However, the high viscosity of the adhesive leads to high resistance during mixing. Too many mixing blades result in excessive resistance to the mixing structure, hindering high-speed rotation and ensuring thorough mixing of the adhesive. Furthermore, too many blades will also accumulate excessive adhesive, increasing the area requiring cleaning. Therefore, we propose an adhesive mixing device for adhesive tape production. Utility Model Content
[0004] The purpose of this invention is to provide an adhesive mixing device for adhesive tape production. By installing a sealing plate inside the mixing tank that can be raised and lowered to adjust its height and seal the bottom of the mixing tank, the raw material liquid placed inside the mixing tank above the sealing plate can rise and fall with the movement of the sealing plate. In this way, the high-speed rotation of a single-layer stirring blade can be used to stir the raw material at various heights, resulting in less resistance and more thorough mixing of the raw material, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adhesive mixing device for adhesive tape production, comprising a mixing tank and a rotating rod. A feed pipe communicating with the interior of the mixing tank is provided on the upper surface of the mixing tank. The rotating rod is rotatably installed in the middle position inside the mixing tank. Stirring blades are fixed on both sides of the bottom of the rotating rod, and the rotating rod is connected to a motor mounted on the upper surface of the mixing tank. A sealing plate that seals the bottom of the mixing tank and is liftable is provided inside the mixing tank. A discharge pipe communicating with the interior of the mixing tank is provided in the middle position of the bottom of the sealing plate. Electric push rods are vertically installed on both sides of the bottom of the mixing tank, with the extended ends of the electric push rods penetrating the inner wall of the mixing tank and fixed to the bottom surface of the sealing plate.
[0006] By adopting the above technical solution, the raw materials are placed inside the mixing tank above the sealing plate. The sealing plate can move the raw materials up and down, and the high-speed rotating stirring blades can then be used to stir the raw materials at different heights, thus achieving a thorough stirring effect and promoting complete mixing.
[0007] Optionally, a scraper ring is provided above the sealing plate, the scraper ring is in contact with the inner surface of the mixing tank, and multiple connecting rods are evenly connected between the scraper ring and the upper surface of the sealing plate.
[0008] By adopting the above technical solution, when the sealing plate is lowered and the raw materials are discharged, the scraper ring can scrape and clean the inner wall of the mixing tank.
[0009] Optionally, a sealing ring is fixed around the outer ring of the sealing plate, and the sealing ring is in contact with the inner wall surface of the mixing tank.
[0010] By adopting the above technical solution, a good sealing effect is ensured between the sealing plate and the inner wall of the mixing tank.
[0011] Optionally, when the sealing plate is raised to its highest position, the scraper ring is in contact with the upper surface inside the mixing tank, and the sealing plate is located below the rotating rod.
[0012] By adopting the above technical solution, the sealing plate is raised to the height of the scraper ring touching the upper surface of the mixing tank, which can play a limiting role and prevent the rotating rod from contacting the sealing plate.
[0013] Optionally, the bottom of the mixing tank is provided with a lower opening, which is located in the middle of the bottom of the mixing tank.
[0014] By adopting the above technical solution, when the sealing plate is lowered to its lowest height, the discharge pipe passes through the lower opening.
[0015] Optionally, the outer ring of the mixing tank is fixed with support legs, and multiple support legs are provided.
[0016] By adopting the above technical solution, multiple support legs are used to support the mixing tank.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0018] 1. The technical solution of this application has a sealing plate inside the mixing tank that can be raised and lowered to adjust its height and seal the bottom of the mixing tank. The raw material liquid placed inside the mixing tank and positioned above the sealing plate can rise and fall with the movement of the sealing plate. In this way, the high-speed rotation of a single layer of stirring blades can be used to stir the raw material at various heights. The resistance encountered is smaller, so the raw material is fully stirred and mixed. Since the number of stirring blades is reduced, the amount of adhesive adhering can be reduced, thus reducing the area and difficulty of cleaning.
[0019] 2. The technical solution of this application sets a scraper ring fixed above the sealing plate and in contact with the inner wall surface of the mixing tank. When the scraper ring descends with the sealing plate, it can scrape off the raw materials adhering to the inner wall surface of the mixing tank, reducing the difficulty of subsequent cleaning.

[0025] Please see Figs. 1-3 This utility model provides a technical solution: an adhesive mixing device for adhesive tape production, including a mixing tank 1 and a rotating rod 2. The outer ring of the mixing tank 1 is fixed with a support leg 13, and multiple support legs 13 are provided to achieve vertical support for the mixing tank 1.
[0026] The upper surface of the mixing tank 1 is provided with a feed pipe 11 that communicates with its interior. Multiple feed pipes 11 are provided, and raw materials can be added into the mixing tank 1 simultaneously through multiple feed pipes 11. The aforementioned rotating rod 2 is rotatably installed in the middle position inside the mixing tank 1. Stirring blades 21 are fixed on both sides of the bottom of the rotating rod 2, and the rotating rod 2 is connected to the motor 22 installed on the upper surface of the mixing tank 1. Starting the motor 22 can drive the rotating rod 2 and the stirring blades 21 to rotate at high speed, thereby agitating the raw materials. The stirring blades 21 are only provided with two single layers, which will be subject to less resistance from the raw materials, ensuring that they can rotate smoothly at high speed and meet the requirements for high-speed agitation of the raw materials.
[0027] To ensure the raw materials are thoroughly agitated and mixed, a liftable sealing plate 3 is installed inside the mixing tank 1. A sealing ring 31 is fixed around the outer ring of the sealing plate 3, and the sealing ring 31 is in contact with the inner wall surface of the mixing tank 1, thereby sealing the bottom of the mixing tank 1 with the sealing plate 3. Electric push rods 32 are vertically installed on both sides of the bottom of the mixing tank 1. The protruding end of the electric push rod 32 passes through the inner wall of the mixing tank 1 and is fixed to the bottom surface of the sealing plate 3. The raw materials are placed in the tank above the sealing plate 3. The liquid raw materials can rise and fall with the lifting and lowering movement of the sealing plate 3. In this way, the high-speed rotation of the single-layer stirring blade 21 can be used to agitate the raw materials at various heights. Furthermore, since the number of stirring blades 21 is reduced, the amount of adhesive can be reduced, thus reducing the area and difficulty of subsequent cleaning.
[0028] A discharge pipe 33, which communicates with the interior of the mixing tank 1, is also provided at the bottom center of the sealing plate 3. The bottom of the mixing tank 1 has a lower opening 12, which is located at the bottom center of the mixing tank 1. After the valve controlling the opening and closing is installed on the discharge pipe 33, when the valve is opened, the mixed raw materials can be discharged from the discharge pipe 33. When the sealing plate 3 is lowered to the lowest position, the discharge pipe 33 passes through the lower opening 12 to the outside.
[0029] A scraper ring 4 is provided above the sealing plate 3. The scraper ring 4 is in contact with the inner surface of the mixing tank 1. Multiple connecting rods 41 are evenly connected between the scraper ring 4 and the upper surface of the sealing plate 3. When the sealing plate 3 is lowered and the raw material is discharged, the scraper ring 4 can scrape and clean the inner wall of the mixing tank 1. When the sealing plate 3 is raised to the highest position, the scraper ring 4 is in contact with the upper surface inside the mixing tank 1. The sealing plate 3 is located below the rotating rod 2, which can play a limiting role and prevent the rotating rod 2 from contacting the sealing plate 3.
[0030] In use, a valve is installed on the discharge pipe 33 to control its opening and closing, connecting both the electric actuator 32 and the motor 22 to the industrial control equipment. First, the electric actuator 32 is controlled to raise the sealing plate 3 to its highest position within the mixing tank 1 (see...). Fig. 3The raw materials are fed into the mixing tank 1 through the feed pipe 11, ensuring the liquid level does not exceed the height of the scraper ring 4. Then, the motor 22 is started, driving the rotating rod 2 and the stirring blade 21 to rotate at high speed to agitate the raw materials. During this process, the electric actuator 32 is controlled to repeatedly lower and raise the sealing plate 3, allowing the stirring blade 21 to perform high-speed and thorough agitation of the liquid at different heights, ensuring the raw materials are fully mixed. After mixing, when it is necessary to discharge the material, the motor 22 is stopped, stopping the rotation of the rotating rod 2 and the stirring blade 21, and the sealing plate 3 is positioned... At the highest position, open the valve installed on the discharge pipe 33 to discharge the raw material. During the discharge process, control the electric push rod 32 to slowly lower the sealing plate 3. When the sealing plate 3 lowers, it also lowers the scraper ring 4, which can scrape off and clean the raw material on the inner wall surface of the mixing tank 1. After the raw material is discharged, close the valve. Then, use the electric push rod 32 to raise the sealing plate 3 to the highest position. Clean water can be introduced into the mixing tank 1 through the feed pipe 11. Start the motor 22 to stir the clean water, thereby cleaning the inside of the mixing tank 1. Finally, discharge the cleaned water from the discharge pipe 33.
