Description

Technical Field

[0001] This utility model relates to the technical field of pressure-sensitive adhesive production equipment, specifically to a pressure-sensitive adhesive stirring device. Background Technology

[0002] Aluminum foil tape is a functional composite material consisting of aluminum foil and a pressure-sensitive adhesive layer. The aluminum foil, with its excellent light-shielding, thermal conductivity, and corrosion resistance, serves as a protective material. The pressure-sensitive adhesive, on the other hand, acts as an adhesive medium, forming a stable bond with the components to be bonded through contact pressure. It is mainly used for efficient sealing of various pipeline systems and has wide applications in HVAC, water supply and drainage, and chemical transportation.

[0003] Currently, most mainstream aluminum foil tapes use polyacrylate pressure-sensitive adhesives as the adhesive. Polyacrylate pressure-sensitive adhesives have moderate initial tack, good holding power, and a wide temperature adaptability range. However, in actual production, because the polyacrylate molecular chain contains hydrophilic groups such as ester groups, the material easily absorbs moisture from the environment during high-speed stirring. Moisture intrusion will destroy the stability of the colloid, causing abnormal viscosity fluctuations at best, and triggering cross-linking reactions leading to gelation at worst, ultimately directly affecting the peel strength of the finished product. Therefore, it is necessary to provide a pressure-sensitive adhesive stirring device to improve the above problems. Summary of the Invention

The cylinders 7 are parallel to the stirring shaft 8. A sealing cover 9 is fixedly connected to the end of the cylinder 7 away from the housing 3. The stirring shaft 8 passes through the sealing cover 9. An air extraction pipe 10 is disposed inside the housing 3.

The cylinders 7 push the sealing cover 9 to move up and down, realizing the sealing and opening of the mixing container. The air extraction pipe 10 removes internal moisture during the mixing process to prevent the pressure-sensitive adhesive from absorbing moisture.

[0022] To achieve active removal of moisture from the inside of the mixing container, the technical solution provided in this embodiment is as follows: the suction pipe 10 is connected to the first output port of the suction pump 11, the suction pump 11 is mounted above the base 1, and the suction pipe 10 is equipped with an air valve 12 on the outside of the housing 3. The suction pump 11 is electrically connected to a controller. The controller starts the suction pump 11, and the suction rate is adjusted by the air valve 12 to discharge the water vapor generated during the mixing process in real time, maintaining a dry environment.

[0023] To unify the power source and achieve centralized control of pneumatic components, the technical solution provided in this embodiment is as follows: Cylinder 7 is connected to the second output port of the vacuum pump 11, and cylinder 7 is electrically connected to the controller through a reversing valve. The vacuum pump 11 simultaneously provides air to cylinder 7, and the controller controls the lifting and lowering action of cylinder 7 through the reversing valve to achieve automatic opening and closing of the sealing cover 9, thereby improving the equipment integration and the level of operational automation.

[0024] To enhance the sealing of the mixing zone and accommodate the lifting and lowering movement of the sealing cap, the technical solution provided in this embodiment is as follows: a bellows 13 is provided between the housing 3 and the sealing cap 9. The bellows 13 is sleeved around the outer periphery of the exhaust pipe 10 and the mixing shaft 8, and the bellows 13 is connected to both the housing 3 and the sealing cap 9 by flanges. The bellows 13 expands and contracts with the lifting and lowering of the sealing cap 9, maintaining a seal while allowing axial movement, preventing external moisture from entering, and protecting the internal components.

[0025] To improve the sealing effect between the sealing cap and the mixing container, the technical solution provided in this embodiment is as follows: Multiple wedge-shaped blocks 14 are arranged in a ring at the lower part of the sealing cap 9. A notch with a width of 0.5-1 cm is provided between adjacent wedge-shaped blocks 14, and a silicone block 15 is fixedly placed within the notch.
