Description

Technical Field

[0001] This invention relates to the field of polyurethane resin processing technology, specifically to a polyurethane resin processing emulsification kettle. Background Technology

[0002] In the field of polyurethane resin processing, emulsifying kettles are the core equipment for shearing, mixing, and homogenizing resin raw materials. Their operational stability and cleaning efficiency directly affect product quality and production continuity. Although conventional emulsifying kettles on the market can complete basic emulsification operations through stirring components, they have gradually revealed several technical shortcomings in long-term use, making it difficult to meet the demands for efficient and precise production.

[0003] However, in the existing polyurethane resin processing emulsification kettle, the stirring rod, as the core execution component of the emulsification process, is prone to material adhering to the surface of the rod due to the high viscosity of polyurethane resin when rotating at high speed. If it is not cleaned in time, the residual material will gradually solidify with temperature changes, which not only affects the purity and emulsification uniformity of subsequent batches of material, but also requires manual disassembly of the equipment for scraping and cleaning. This not only increases the labor intensity of operators, but also prolongs equipment downtime, reduces production efficiency, and causes raw material waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a polyurethane resin processing emulsifying kettle, which solves the problems of difficult cleaning of material residue on the surface of the stirring rod of existing emulsifying kettles, long cleaning time, high manual labor intensity, and easy waste of raw materials and fluctuations in product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polyurethane resin processing emulsifying kettle, comprising an emulsifying kettle body installed inside a frame, a controller installed on the outside of the frame, a movable plate slidably connected to the top of the frame, a cylinder installed at the bottom of the movable plate, the cylinder being installed inside the frame, a connecting plate installed on the surface of the movable plate, and an emulsifying kettle cover provided at the bottom of the connecting plate; a stirring rod provided at the bottom of the emulsifying kettle cover; further comprising a movable component for cleaning the surface of the stirring rod; a swinging component for scraping material off the inner wall of the emulsifying kettle body; and a limiting component for restricting the stirring rod during operation. The time limit is specified; the active component includes: a drive motor, which is mounted on the top of the connecting plate, a fixed shaft sleeved on the surface of the drive motor, a fixed frame mounted on the outside of the fixed shaft, the fixed frame mounted on the bottom of the emulsification kettle cover, a stirring rod fixedly mounted on the surface of the drive motor, a reciprocating lead screw mounted at the middle end of the stirring rod, a slider threadedly connected to the surface of the reciprocating lead screw, the slider slidably connected to the bottom of the fixed shaft, a fixed disk mounted on the surface of the slider, a movable rod rotatably connected inside the fixed disk, a cleaning ring mounted on the surface of the movable rod, and the cleaning ring slidably connected to the surface of the stirring rod.

[0006] Preferably, the cross-section of the fixing frame is U-shaped, and the surface of the fixing plate is provided with an annular groove.

[0007] Preferably, there are eight cleaning rings, and all eight cleaning rings are arranged in a circular array with the center point of the stirring rod as the center.

[0008] Preferably, the oscillating assembly includes: a connecting shaft, the connecting shaft being installed at the bottom of the stirring rod, a fixing plate being installed at the bottom of the connecting shaft, a fixing block being installed at the top of the fixing plate, a telescopic rod being installed inside the fixing block, and a fixing spring being installed on the surface of the telescopic rod.

[0009] Preferably, a movable block is mounted on the surface of the telescopic rod, a rotating shaft is rotatably connected to the top of the movable block, a scraper is mounted on the top of the rotating shaft, a spiral spring is mounted on the surface of the rotating shaft, and the spiral spring is mounted on the top of the movable block.

[0010] Preferably, the cross-section of the scraper is arc-shaped, and the surface of the fixing block is provided with a groove.

[0011] Preferably, the limiting component includes: a shaft, which is rotatably connected to the bottom of the fixed plate, and a strip is installed on the outside of the shaft.

[0012] Preferably, a limiting shaft is installed inside the emulsifying tank body, and a limiting strip is installed inside the limiting shaft.

[0013] Preferably, the limiting shaft has a circular groove inside, and the cross-sections of the insert and the limiting strip are both rectangular.

[0014] Compared with the prior art, the present invention provides a polyurethane resin processing emulsifying kettle, which has the following beneficial effects: 1. This polyurethane resin processing emulsification kettle utilizes a movable component design. After the drive motor starts, the output shaft is rigidly connected to the stirring rod via a coupling, transmitting rotational power. When the motor runs, it synchronously drives the reciprocating screw at the middle end of the stirring rod to rotate. The slider is sleeved outside the reciprocating screw, and its top is slidably connected to the fixed shaft via a sliding sleeve. Due to the guidance restriction of the fixed shaft, the slider cannot rotate with the screw; it can only reciprocate up and down along the shaft. When it reaches the limit position of the spiral groove, it automatically reverses direction. The fixed plate outside the slider moves synchronously, and the movable rod in its annular groove drives the cleaning ring to slide against the stirring rod. The inner nylon scraper removes material residue, reducing waste and improving cleaning efficiency.

[0015] 2. This polyurethane resin processing emulsification kettle utilizes a swing assembly. When the stirring rod rotates, torque is transmitted through a connecting shaft connected by a key at the bottom, causing the fixed plate to rotate coaxially. Inside the fixed block on the surface of the fixed plate, the fixed spring on the outside of the telescopic rod uses centrifugal force to push the moving block against the kettle wall. The top of the moving block is hinged to a scraper via a rotating shaft. The pre-tensioned spiral spring ensures that the arc-shaped surface of the scraper fits against the kettle wall. As the fixed plate rotates, the scraper moves along the kettle wall. The arc-shaped structure covers the entire contact area without dead corners, efficiently removing residues, ensuring cleaning effect and extending service life.

[0016] 3. In this polyurethane resin processing emulsifying kettle, the fixed component is designed so that before the stirring rod drives the fixed plate to rotate, the insertion shaft at the bottom of the fixed plate is first inserted into the circular groove of the limiting shaft inside the emulsifying kettle under the action of the drive motor, forming a preliminary axial positioning. The rectangular insertion strip on the outside of the insertion shaft is precisely matched with the rectangular limiting strip on the inner wall of the circular groove. During rotation, they are tightly engaged. The insertion strip and the limiting strip abut against each other to offset the lateral force, prevent the component from deviating from the axis, ensure the stability of the cleaning trajectory, and improve the cleaning efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 As shown, a polyurethane resin processing emulsifying kettle includes an emulsifying kettle body 2 installed inside a frame 1, a controller 11 installed on the outside of the frame 1, a movable plate 3 slidably connected to the top of the frame 1, a cylinder 4 installed at the bottom of the movable plate 3, the cylinder 4 installed inside the frame 1, a connecting plate 5 installed on the surface of the movable plate 3, an emulsifying kettle cover 6 provided at the bottom of the connecting plate 5, and a stirring rod 10 provided at the bottom of the emulsifying kettle cover 6. It also includes a movable component 7 for cleaning the surface of the stirring rod 10; The oscillating component 8 is used to scrape material off the inner wall of the emulsifying kettle body 2; Limiting component 9 is used to limit the stirring rod 10 during use; First, the active component 7 includes: a drive motor 71, which is mounted on the top of the connecting plate 5; a fixed shaft 72 is sleeved on the surface of the drive motor 71; a fixed bracket 78 is mounted on the outside of the fixed shaft 72; the fixed bracket 78 is mounted on the bottom of the emulsifying kettle cover 6; a stirring rod 10 is fixedly mounted on the surface of the drive motor 71; a reciprocating lead screw 73 is mounted in the middle of the stirring rod 10; a slider 74 is threaded onto the surface of the reciprocating lead screw 73; the slider 74 is slidably connected to the bottom of the fixed shaft 72; a fixed plate 75 is mounted on the surface of the slider 74; a movable rod 76 is rotatably connected inside the fixed plate 75; a cleaning ring 77 is mounted on the surface of the movable rod 76; and the cleaning ring 77... 7 is slidably connected to the surface of the stirring rod 10. By using the drive motor 71 as a power source, the stirring rod 10 and the reciprocating screw 73 are driven to rotate synchronously. With the help of the threaded engagement between the reciprocating screw 73 and the slider 74, and the sliding constraint between the slider 74 and the fixed shaft 72, the rotational motion is converted into the up-and-down reciprocating motion of the slider 74. Then, the power is transmitted to the movable rod 76 through the fixed plate 75. Utilizing the rotational adaptability of the movable rod 76 within the fixed plate 75, the cleaning ring 77 is driven to slide tightly against the surface of the stirring rod 10. Ultimately, the rotational emulsification of the stirring rod 10 and the real-time cleaning of surface residue are carried out simultaneously, avoiding material solidification and adhesion, and reducing manual cleaning steps.

[0021] Secondly, the fixed frame 78 has a U-shaped cross-section, and the surface of the fixed plate 75 has an annular groove 750. The fixed frame 78 adopts a U-shaped cross-section design and is stably connected to the bottom of the emulsification kettle cover 6 through the support arms on both sides, providing rigid support for the fixed shaft 72, while reserving operating space for the stirring rod 10 and the reciprocating screw 73 to avoid interference between components. The annular groove 750 on the surface of the fixed plate 75 provides rotation trajectory constraint for the movable rod 76. The annular structure ensures that the movable rod 76 can adaptively adjust its angle along the annular trajectory when moving up and down with the fixed plate 75, ensuring that the cleaning ring 77 is always in contact with the stirring rod 10, avoiding the centrifugal force generated by the rotation of the stirring rod 10 from causing the cleaning ring 77 to shift, thus improving cleaning stability. There are eight cleaning rings 77, and all eight cleaning rings 77 are arranged in a circular array with the center point of the stirring rod 10 as the center.

[0022] Furthermore, the oscillating assembly 8 includes: a connecting shaft 81, which is installed at the bottom of the stirring rod 10; a fixing plate 82 is installed at the bottom of the connecting shaft 81; a fixing block 83 is installed at the top of the fixing plate 82; a telescopic rod 84 is installed inside the fixing block 83; a fixing spring 85 is installed on the surface of the telescopic rod 84; a moving block 86 is installed on the surface of the telescopic rod 84; a rotating shaft 87 is rotatably connected to the top of the moving block 86; a scraper 88 is installed at the top of the rotating shaft 87; and a spiral spring 89 is installed on the surface of the rotating shaft 87. At the top of the moving block 86, the rotational power of the stirring rod 10 is transmitted to the fixed plate 82 through the connecting shaft 81, so that the swing assembly 8 and the stirring rod 10 operate synchronously. With the elastic cooperation of the telescopic rod 84 inside the fixed block 83 and the fixed spring 85, the preload of the fixed spring 85 pushes the telescopic rod 84 to extend outward, which drives the subsequent scraper 88 assembly to approach the inner wall of the emulsification tank body 2, providing continuous radial pressure for the scraper 88 to adhere to the tank wall, ensuring that the scraper 88 is always in close contact with the tank wall during the scraping process, and avoiding the accumulation of material residue.

[0023] Furthermore, the scraper 88 has an arc-shaped cross-section, and the fixing block 83 has a groove 830 on its surface. The scraper 88 adopts an arc-shaped cross-section design, and its curvature is perfectly matched with the curvature of the inner wall of the emulsification vessel body 2, so that the scraper 88 forms a line contact with the vessel wall, increasing the scraping area and avoiding the local missed scraping problem that exists with right-angle or flat scrapers 88, ensuring that there are no dead corners left on the vessel wall. The groove 830 on the surface of the fixing block 83 provides extension and retraction space for the telescopic rod 84, and guides the movement direction of the telescopic rod 84 to prevent the telescopic rod 84 from deviating during extension and retraction, ensuring the radial movement accuracy of the scraper 88 and improving the stability of the wall scraping.

[0024] Furthermore, the limiting component 9 includes: a shaft 91 rotatably connected to the bottom of the fixed plate 82; a strip 92 installed on the outside of the shaft 91; a limiting shaft 93 installed inside the emulsifying vessel body 2; and a limiting strip 94 installed inside the limiting shaft 93. By rotatably connecting the shaft 91 to the bottom of the fixed plate 82, the shaft 91 can rotate synchronously with the fixed plate 82. At the same time, the strip 92 on the outside of the shaft 91 provides an engagement structure for subsequent cooperation with the limiting shaft 93. The rigid structure of the strip 92 can transmit torque constraint. When the stirring rod 10 shows a tendency to wobble radially, the strip 92 can abut against the internal structure of the limiting shaft 93 to counteract the lateral force, prevent the stirring rod 10 from deviating, and ensure the coaxiality of the stirring and scraping components.

[0025] Finally, a circular groove 930 is provided inside the limiting shaft 93. The cross-sections of the insert bar 92 and the limiting bar 94 are both rectangular. The circular groove 930 inside the limiting shaft 93 provides an insertion space for the insert shaft 91, and at the same time, the radial movement of the insert shaft 91 is initially constrained by the circular inner wall. The insert bar 92 and the limiting bar 94 adopt a rectangular cross-section design. Compared with circular or arc-shaped structures, the rectangular mating surface has a larger contact area and can withstand stronger lateral forces, avoiding slippage during meshing. This further enhances the ability to limit the shaking of the stirring rod 10 and ensures the stability of the equipment under high load operation.

[0026] Working principle: The polyurethane resin processing emulsifying kettle uses the controller 11 as the core control unit. Through preset programs or manual operation commands, it coordinates the operation sequence and action logic of key components such as the frame 1, cylinder 4, and drive motor 71. It integrates four major functions: material emulsification, cleaning of the stirring rod 10, scraping of the kettle wall, and stable stirring control, forming an automated and efficient polyurethane resin processing flow. When the equipment is in standby mode, the emulsifying kettle body 2 is fixed to the support structure inside the frame 1, and the kettle opening is in an open state. The movable plate 3 is connected to the top of the frame 1 through a slide rail. Its initial position is at a high position above the frame 1, ensuring that the top of the emulsifying kettle body 2 is unobstructed, which facilitates the initial feeding of raw materials. The piston rod of the cylinder 4 is in a retracted state, and its cylinder body is fixed to the load-bearing crossbeam inside the frame 1 by bolts, providing a stable thrust output foundation. The emulsifying kettle cover 6 is rigidly connected to the movable plate 3 through the connecting plate 5, and is synchronously positioned at a high position with the movable plate 3, maintaining a vertical distance from the emulsifying kettle body 2.

[0027] After the operator sends a command through the controller 11, the controller 11 outputs an electrical signal to the solenoid reversing valve of the cylinder 4, controlling the cylinder 4 to ventilate. Compressed air enters the rodless chamber of the cylinder 4, pushing the piston rod downward. The top of the piston rod is hinged to the connecting seat at the bottom of the movable plate 3 via a pin, thereby driving the movable plate 3 to move vertically downward along the slide rail at the top of the frame 1. During the downward movement of the movable plate 3, the bottom fixed connecting plate 5 and the emulsifying kettle cover 6 below the connecting plate 5 move downward simultaneously. The bottom of the emulsifying kettle cover 6 is equipped with an oil-resistant rubber sealing ring. When it moves down to fit against the flange surface at the top of the emulsifying kettle body 2, the controller 11 detects the position signal through the stroke sensor of the cylinder 4, controls the cylinder 4 to stop ventilating and maintain pressure, thereby sealing the emulsifying kettle body 2 and preventing material leakage or the entry of external impurities during subsequent emulsification. After the kettle body is sealed, a start signal is output to the drive motor 71 installed on the top of the connecting plate 5. After the drive motor 71 is powered on, its output shaft is rigidly connected to the top of the stirring rod 10 through a coupling, directly transmitting the rotational power. When the stirring rod 10 is moved and the drive motor 71 is running, its output shaft not only drives the stirring rod 10 to rotate, but also synchronously drives the reciprocating screw 73 installed in the middle of the stirring rod 10 to rotate. A slider 74 is fitted on the outer side of the reciprocating screw 73. At the same time, the top of the slider 74 is slidably connected to the fixed shaft 72 through a sliding sleeve. Its top end is fixed below the emulsification kettle cover 6 by a fixing bracket 78. The axis is parallel to the stirring rod 10, forming a guiding constraint on the slider 74. When the reciprocating screw 73 rotates synchronously with the stirring rod 10, the slider 74 is subjected to The fixed shaft 72, due to its guiding limitation, cannot rotate synchronously with the reciprocating screw 73. It can only reciprocate up and down along the axis of the fixed shaft 72. The bidirectional helical groove of the reciprocating screw 73 drives the slider 74 to move along the helical groove trajectory through threaded transmission. When the slider 74 moves to the limit position at one end of the helical groove, it automatically switches the direction of motion under the reverse guiding action of the helical groove, thereby realizing continuous up and down reciprocating motion. A fixed plate 75 is fixed to the outside of the slider 74 by bolts. The fixed plate 75 moves up and down synchronously with the slider 74. Eight movable rods 76 are evenly distributed in the annular groove 750 of the fixed plate 75. One end of the movable rod 76 is engaged in the annular groove 750 by a roller and can slide freely along the annular groove 750. The other end is hinged to the outer wall of the cleaning ring 77. When the fixed plate 75 moves up and down, the movable rod 76, constrained by the annular groove 750, moves up and down synchronously with the fixed plate 75, and can also slide adaptively along the annular groove 750 according to the rotation state of the stirring rod 10. This causes the cleaning ring 77 to always be in contact with the surface of the stirring rod 10 and slide up and down. During the sliding process, the scraper 88 on the inner side of the cleaning ring 77 can efficiently scrape off the polyurethane resin material residue attached to the surface of the stirring rod 10, avoiding the residual material from solidifying and affecting the subsequent stirring effect. At the same time, it reduces material waste, reduces the difficulty of equipment cleaning and maintenance, and improves cleaning efficiency.

[0028] When the stirring rod 10 rotates, it transmits torque through the connecting shaft 81 connected by the bottom key, causing the bottom fixing plate 82 to rotate synchronously and coaxially. Fixing blocks 83 are evenly distributed along the circumference of the surface of the fixing plate 82. A telescopic rod 84 is fitted inside the groove 830 of the fixing block 83. The fixing spring 85 on the outside of the telescopic rod 84 is in a relaxed state. The centrifugal force generated by the rotation of the fixing disc 75 continuously pushes the moving block 86 at the end of the telescopic rod 84, ensuring it always tends to move closer to the inner wall of the emulsification vessel body 2. This provides a basic radial thrust for the scraper 88 to adhere to the vessel wall. The top of the moving block 86 is hinged to the scraper 88 via a rotating shaft 87. The spiral spring 89 on the outside of the rotating shaft 87 is initially pre-tightened, and the torque causes the arc-shaped working surface of the scraper 88 to tightly adhere to the vessel wall. As the fixed plate 82 rotates, the scraper 88 moves circumferentially along the vessel wall. The arc-shaped structure perfectly matches the curvature of the vessel wall, covering the entire contact area of ​​the vessel wall and avoiding the dead corners that exist with right-angle or flat scrapers 88. It efficiently removes the attached polyurethane resin residue. If there are small protrusions or impurities on the vessel wall, the scraper 88 rotates slightly around the rotation axis 87 under the reaction force. The spiral spring 89 deforms accordingly to buffer the impact force and prevent the scraper 88 from rigidly colliding with the vessel wall and causing wear. When the obstacle is cleared, the spiral spring 89 rebounds to reset the scraper 88, maintaining a continuous contact state. This ensures the cleaning effect of the scraper and extends the service life of the components.

[0029] Before the stirring rod 10 drives the fixed plate 82 to rotate via the connecting shaft 81, the insert shaft 91, which is coaxially fixed at the bottom of the fixed plate 82, is inserted into the circular groove 930 of the pre-set limiting shaft 93 inside the emulsifying tank body 2 under the action of the drive motor 71, forming a preliminary axial positioning. Rectangular insert strips 92 are evenly distributed axially on the outer side of the insert shaft 91, while rectangular limiting strips 94 are correspondingly set on the inner wall of the circular groove 930 of the limiting shaft 93. The two are precisely matched in size and achieve tight engagement as the stirring rod 10 rotates. This engagement structure can directly limit the radial displacement of the stirring rod 10 when it rotates at high speed. When the moving component 7 and the swing component 8 tend to shake due to the resistance of the material, the sides of the insert strips 92 and the limiting strips 94 abut against each other, offsetting the lateral force and preventing the moving component 7 and the swing component 8 from deviating from the axis. The stable cleaning trajectory makes the moving component 7 and the swing component 8 more stable and efficient in cleaning the material adhering to the emulsifying tank body 2.

[0030] After emulsification is completed, the drive motor 71 stops running, the cylinder 4 contracts and drives the emulsification kettle cover 6 and each component to rise and reset, the cleaning ring 77 returns to its initial position under the reverse rotation of the reciprocating screw 73, the scraper 88 rebounds slightly under the action of the spiral spring 89, and the insertion shaft 91 rises with the fixed plate 82 and disengages from the limiting shaft 93, which facilitates subsequent unloading and equipment maintenance.
