AI Technical Summary
The existing polyacrylate pressure-sensitive adhesive reactor has a stirring mechanism in a constant position, which makes it difficult to effectively stir areas far from the stirring paddle, resulting in a slow mixing speed.
The motor-driven rotating rod drives the connecting pipe to rotate through a linear slide groove and a slide bar. Combined with the meshing of the first and second gears, the guide ring and the connecting pipe rotate in opposite directions. The guide rod slides in the guide groove, driving the stirring rod to move up and down, expanding the stirring range and improving the mixing efficiency.
The coordinated movement of the guide rod and the stirring rod increases the stirring range and mixing speed, thereby improving the stirring efficiency of the polyacrylate pressure-sensitive adhesive.

Abstract
Description
Technical Field
[0001] This application relates to the field of polyacrylate pressure-sensitive adhesive processing technology, and in particular to a stirring and mixing reactor for polyacrylate pressure-sensitive adhesive. Background Technology
[0002] Polyacrylate pressure-sensitive adhesive is an adhesive based on polyacrylate resin, commonly used in various applications requiring adhesion at room temperature, such as labels, tapes, and stickers. The characteristic of pressure-sensitive adhesive is that it can adhere directly to the substrate surface without external heat or pressure. A mixing reactor is required in the processing of polyacrylate pressure-sensitive adhesive.
[0003] The existing polyacrylate pressure-sensitive adhesive reactor includes a reactor body, a stirring device, a condenser, and a liquid distributor. The stirring device consists of a motor-driven stirring shaft and a stirring paddle. The liquid distributor is a homogenizing plate with distribution holes. The condenser is connected to the liquid distributor via a reflux pipe. The reactor walls can be cleaned in real time using the liquid distributor and the stirring device.
[0004] However, in actual use, the stirring mechanism is in a constant position, making it difficult to stir areas far from the stirring paddle. The only way to improve the reaction efficiency is to increase the stirring time, which results in a slow mixing speed of the raw materials during the stirring process. Therefore, this needs to be improved. Utility Model Content
[0005] To increase the stirring range and improve stirring efficiency, this application provides a stirring and mixing reactor for polyacrylate pressure-sensitive adhesive.
[0006] The stirred mixing reactor for a polyacrylate pressure-sensitive adhesive provided in this application adopts the following technical solution:
[0007] A stirring and mixing reactor for polyacrylate pressure-sensitive adhesive includes a reactor body and a stirring mechanism. The stirring mechanism includes a speed reducer, with a motor fixedly installed at the input end of the speed reducer and a rotating rod installed at the output end. A connecting pipe is sleeved on the outer surface of the rotating rod. Two sets of linear grooves are formed on the inner wall of the connecting pipe. A slide bar is slidably connected to the inner wall of each linear groove. The side of each slide bar near the rotating rod is fixedly installed to the outer surface of the rotating rod. A mounting ring is rotatably mounted on the outer surface of the connecting pipe via a bearing. Two guide rods are fixedly mounted on the outer surface of the mounting ring. A perforated disc is fitted onto the outer surface of the tube. A T-shaped groove is formed on the upper surface of the perforated disc. A T-shaped slip ring is slidably connected to the inner wall of the T-shaped groove. A guide ring is fixedly installed on the upper surface of the T-shaped slip ring. A guide groove is formed on the inner wall of the guide ring. The ends of the two guide rods that are far apart from each other extend into the interior of the two guide grooves respectively. A toothed ring is fixedly installed on the outer surface of the guide ring. A first gear is fixedly installed on the outer surface of the rotating rod. A rotating shaft is rotatably installed on the inner top wall of the vessel body through a bearing. A second gear is fixedly installed at the bottom end of the rotating shaft. A set of stirring rods is fixedly installed on the outer surface of the connecting tube.
[0008] By adopting the above technical solution, the raw materials are added into the reactor body through the feed pipe and the filling pipe during use. At the same time, the electric heating plate is activated to raise the internal temperature of the reactor body. Then, the motor is started, and the motor drives the rotating rod to rotate through the reducer. The rotating rod drives the connecting pipe to rotate through the linear slide groove and the slide bar. The connecting pipe drives the stirring rod to rotate. At the same time, the first gear, through its meshing with the second gear, can drive the second gear to rotate the gear ring. The gear ring drives the guide ring to rotate in the opposite direction to the connecting pipe. During the rotation of the guide ring, the guide rod can slide inside the guide groove, thereby causing the guide rod to drive the connecting pipe and the stirring rod to slide up and down. This allows the stirring rod to stir the raw materials at different positions, improving the mixing speed. After processing is completed, the control valve is opened to allow the pressure-sensitive adhesive to be discharged through the discharge pipe and the control valve.
[0009] Optionally, the first gear meshes with the second gear, and the second gear meshes with the ring gear.
[0010] By adopting the above technical solution, the cooperation of the first gear, the second gear, and the gear ring can enable the gear ring to drive the guide ring to rotate, thereby enabling the guide ring to rotate in the opposite direction to the connecting pipe.
[0011] Optionally, a feed pipe is fixedly connected to the left side of the vessel body, and a feeding pipe is fixedly connected to the right side of the vessel body.
[0012] By adopting the above technical solution, the feed pipe can add the main raw material, and the feeding pipe can add the auxiliary raw material, thus preventing the raw materials from interfering with each other.
[0013] Optionally, a discharge pipe is fixedly connected to the bottom surface of the vessel body, and a control valve is fixedly connected to the bottom end of the discharge pipe.
[0014] By adopting the above technical solution, the discharge pipe and control valve can easily control the discharge of raw materials.
[0015] Optionally, a connecting cylinder is fixedly installed on the outer surface of the vessel body, a set of electric heating plates is fixedly installed on the inner wall of the connecting cylinder, and a set of support legs is fixedly installed on the outer surface of the connecting cylinder.
[0016] Optionally, a fixing ring is fixedly installed on the bottom surface of the perforated disc, and the outer surface of the fixing ring is fixedly installed to the inner wall of the vessel.
[0017] By adopting the above technical solution, the fixing ring can reinforce the perforated disk, increase the stability of the perforated disk, and prevent the perforated disk from becoming loose.
[0018] Optionally, a support ring is fixedly installed on the outer surface of the guide ring, and the inner wall of the support ring is fixedly installed on the outer surface of the toothed ring.
[0019] By adopting the above technical solution, the support ring can support the gear ring, increase the stability of the gear ring, and prevent the gear ring from separating from the second gear.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. By using a motor, rotating rod, linear slide groove and slide bar in cooperation, the connecting pipe can be rotated. By using the cooperation of the first gear, the second gear and the gear ring, the guide ring can be rotated in the opposite direction to the connecting pipe. In turn, the guide ring can control the installation ring to move up and down through the guide rod, and the installation ring can control the connecting pipe to move up and down. This allows the connecting pipe to drive the stirring rod to move up and down during the stirring of raw materials, increasing the stirring range of the stirring rod and improving the stirring efficiency.
[0022] 2. During use, the raw materials are added into the reactor body through the feed pipe and the filling pipe. At the same time, the electric heating plate is activated to raise the internal temperature of the reactor body. Then, the motor is started. The motor drives the rotating rod to rotate through the reducer. The rotating rod drives the connecting pipe to rotate through the linear slide groove and the slide bar. The connecting pipe drives the stirring rod to rotate. At the same time, the first gear meshes with the second gear, which drives the gear ring to rotate. The gear ring drives the guide ring to rotate in the opposite direction to the connecting pipe. During the rotation of the guide ring, the guide rod can slide inside the guide groove, thereby causing the guide rod to drive the connecting pipe and the stirring rod to slide up and down. This allows the stirring rod to stir the raw materials at different positions, improving the mixing speed. After processing is completed, the control valve is opened to discharge the pressure-sensitive adhesive through the discharge pipe and the control valve. Attached Figure Description

The motor 203 drives the rotating rod 210 to rotate via the reducer 202. The rotating rod 210 drives the connecting pipe 211 to rotate via the linear slide groove 218 and the slide bar 219. The connecting pipe 211 drives the stirring rod 205 to rotate. Simultaneously, the first gear 215 interacts with the second gear... The meshing action of the gear 217 can cause the second gear 217 to drive the gear ring 209 to rotate. The gear ring 209 drives the guide ring 208 to rotate in the opposite direction to the connecting pipe 211. During the rotation of the guide ring 208, the guide rod 214 can slide inside the guide groove 212, thereby causing the guide rod 214 to drive the connecting pipe 211 and the stirring rod 205 to slide up and down. This allows the stirring rod 205 to stir the raw materials at different positions, improving the mixing speed. After processing, the control valve 105 is opened, allowing the pressure-sensitive adhesive to be discharged through the discharge pipe 104 and the control valve 105.
