Description
Technical Field
[0001] This application relates to the field of adhesive processing technology, and in particular to a defoaming device for post-treatment of water-based adhesives. Background Technology
[0002] Adhesives are a class of organic or inorganic, natural or synthetic substances that can bond together one or more homogeneous or heterogeneous parts (or materials) and have sufficient strength after curing. Epoxy resin adhesives, due to their high bonding strength and versatility, were once known as "all-purpose glue" or "super glue" and are widely used in aviation, aerospace, automotive, machinery, construction, chemical, light industry, electronics, electrical appliances and daily life.
[0003] Chinese Patent Publication No. CN218961842U discloses an adhesive defoaming device, including a tank body, a stirring shaft disposed in the middle of the feed pipe, the stirring shaft being connected to a drive motor via a vibration connection device, a feed pipe disposed at the top of the tank body, and a discharge pipe disposed at the bottom of the tank body; a heating jacket disposed in the middle of the tank body; a stirring rod disposed on the stirring shaft; the vibration connection device includes a disc disposed on the first end of a connecting rod, a baffle disposed at the end of the connecting rod, and a mounting sleeve for placing the stirring shaft disposed below the baffle; a shaft hole disposed in the middle of the disc and the connecting rod, and a connecting shaft disposed on the output shaft of the drive motor that mates with the shaft hole; a groove disposed on the lower surface of the disc, and a ball bearing disposed on the top of the tank body that mates with the groove. The purpose of this utility model is to provide an adhesive defoaming device that can accelerate the elimination of bubbles in the adhesive, save the time used for defoaming, and improve production efficiency.
[0004] Existing adhesive defoaming devices can eliminate air bubbles inside the adhesive, but when the stirring shaft eliminates air bubbles inside the adhesive, it also drives the adhesive to rotate in the same direction, which reduces the pressure on the adhesive. Some small air bubbles cannot be broken by the pressure inside the adhesive, and it takes a long time for the adhesive to complete the defoaming process. Utility Model Content
[0005] This application provides a defoaming device for post-treatment of water-based adhesives, which can improve the technical problem in related technologies where the stirring shaft, when eliminating bubbles inside the adhesive, also drives the adhesive to rotate in the same direction, reducing the pressure on the adhesive. This results in some small bubbles not being able to break due to the internal pressure of the adhesive, requiring a long time for the adhesive to complete the defoaming process.
[0006] This application provides a defoaming device for post-treatment of water-based adhesives, including a defoaming tank. Multiple legs are fixedly connected to the four feet at the bottom of the defoaming tank. A through hole is opened near the center of the top of the defoaming tank. A sealing ring is fixedly connected inside the through hole. A driving component is slidably connected inside the sealing ring. A defoaming chamber is opened inside the defoaming tank. A defoaming component is arranged inside the defoaming chamber.
[0007] The defoaming component includes a pressurizing assembly and a stirring assembly. The pressurizing assembly includes a connecting column, and a rotating cavity is opened inside the connecting column. A DC motor is fixedly connected inside the rotating cavity. A drive gear is fixedly connected to the output end of the DC motor. Multiple transmission gears are meshed and rotatably connected to the outside of the drive gear. A driven column is fixedly connected to the end of the transmission gear away from the drive gear. A fan blade is fixedly connected to the end of the driven column away from the transmission gear. The fan blade is located outside the connecting column.
[0008] By adopting the above technical solution, when defoaming the adhesive, the driving component drives the stirring component to stir and defoam. However, when only the stirring component is used for defoaming, the ability to treat the foam on the surface of the adhesive is weak. Therefore, a DC motor is used to drive the driving gear to rotate. The driving gear drives the transmission gear on the side to rotate, so that the fan blades on the outside of the connecting column can rotate longitudinally while following the horizontal rotation of the connecting column. The longitudinally rotating fan blades will generate shearing and impact on the surface foam layer, increase the internal pressure of the adhesive, make the foam easier to break, and improve the defoaming efficiency.
[0009] Optionally, the stirring assembly includes a connecting rod, one end of which is fixedly connected to the connecting column, and a sliding ring is slidably connected to the outer wall of the end of the connecting rod away from the connecting column. Multiple stirring rods are fixedly connected to the outer side of the sliding ring, and multiple bubble-piercing rods are provided on both sides of the stirring rod.
[0010] By adopting the above technical solution, the driving component is used to drive the connecting rod to rotate. While rotating, the stirring rod is driven to defoam the air bubbles inside the adhesive. Considering that some small air bubbles cannot be eliminated by the stirring rod, multiple evenly distributed bubble-piercing rods are set on both sides of the stirring rod. The small contact area at the front end of the bubble-piercing rod is used to clean the air bubbles inside the adhesive.
[0011] Optionally, a fixing ring is fixedly connected to the outer side of the connecting rod near the connecting column, and multiple support rods are rotatably connected to the notch on the outer side of the fixing ring. A sliding groove is opened inside the stirring rod, and a clamping block is slidably connected inside the sliding groove. The end of the support rod away from the fixing ring is rotatably connected to the clamping block.
[0012] By adopting the above technical solution, when the drive component drives the connecting rod to move downward, the sliding ring slides upward under the pressure inside the adhesive, thereby defoaming different layers of adhesive and improving the defoaming efficiency.
[0013] Optionally, a second elastic element is provided on the outer side of the connecting rod, one end of the second elastic element abuts against the fixed ring, and the other end of the second elastic element away from the fixed ring abuts against the sliding ring.
[0014] By adopting the above technical solution, the sliding ring presses the second elastic element. When the pressure on the sliding ring decreases, the sliding ring drives the stirring rod back to its original position to continue to eliminate air bubbles in the current layer of adhesive. The buffer of the second elastic element can prevent the pressure generated by the vertical downward connection rod from causing secondary foaming inside the adhesive.
[0015] Optionally, a scraper is rotatably connected to the end of the stirring rod away from the sliding ring, and one side of the scraper is attached to the inner wall of the defoaming chamber.
[0016] By adopting the above technical solution, the air bubbles inside the adhesive may be adsorbed inside the defoaming chamber. Therefore, the scraper on the side of the stirring rod is used to adhere to the inner wall of the defoaming chamber. While the stirring rod is rotating, the scraper can also be driven to clean the inner wall of the defoaming chamber, so as to avoid the air bubbles inside the adhesive adsorbing to the inner wall of the defoaming chamber and affecting the overall defoaming efficiency.
[0017] Optionally, the drive assembly includes a drive motor, the output end of which is fixedly connected to the transmission rod, the end of the transmission rod away from the drive motor is fixedly connected to the connecting column, the end of the drive motor away from the transmission rod is fixedly connected to a support plate, two guide columns are slidably connected inside both ends of the support plate, a first elastic element is provided on the outer side of the guide column, one end of the first elastic element is fixedly connected to the support plate, the end of the first elastic element away from the support plate is fixedly connected to the defoaming tank, a baffle is fixedly connected to the upper end of the guide column, a hydraulic column is fixedly connected to the bottom of the baffle, and the output end of the hydraulic column is fixedly connected to the main support plate.
[0018] By adopting the above technical solution, the drive motor rotates to drive the transmission column to rotate, which in turn drives the defoaming component to rotate. At the same time, the hydraulic column at the bottom of the baffle pushes the support plate to facilitate the up and down movement of the drive motor. When the hydraulic column pushes the support plate downward, the drive motor may experience a slight displacement due to some reasons. The first elastic element can compensate for these displacements through its own elastic deformation, so that the motor remains in a relatively stable position.
[0019] Optionally, the defoaming tank has a discharge port near the center of its bottom, and a sealing block is snapped into the discharge port. The upper surface of the defoaming tank has a feed pipe with a threaded groove on its outer wall. A snap-fit ring is rotatably snapped into the outer wall of the feed pipe. A threaded ring is fixedly connected to one end of the snap-fit ring near the feed pipe. The threaded ring and the threaded groove are engaged. An air extraction pipe is slidably connected to one end of the snap-fit ring away from the feed pipe. A sealing gasket is fixedly connected to the bottom of the air extraction pipe, and the sealing gasket is located inside the snap-fit ring.
[0020] By adopting the above technical solution, in order to prevent the gas generated during stirring from regenerating bubbles, the vacuum pump's internal suction pipe is clamped above the feed pipe. By rotating the clamping ring, the threaded ring inside the clamping ring engages with the threaded groove above the feed pipe. Rotating the clamping ring connects the suction pipe to the feed pipe. At the same time, as the clamping ring moves the suction pipe downward, the feed pipe pushes the sealing gasket to ensure its sealing. The suction pump extracts the gas inside the defoaming tank through the suction pipe, keeping the gas pressure inside the defoaming tank at a stable level and avoiding secondary foaming.
[0021] This utility model application has at least the following effects:
[0022] 1. The mixing component is driven by the drive component to stir and defoam. However, when only the mixing component is used for defoaming, the ability to treat the foam on the surface of the adhesive is weak. Therefore, a DC motor is used to drive the drive gear to rotate. The drive gear drives the transmission gear on the side to rotate, so that the fan blades on the outside of the connecting column can rotate longitudinally while following the horizontal rotation of the connecting column. The longitudinally rotating fan blades will generate shearing and impact on the surface foam layer, increase the internal pressure of the adhesive, make the foam easier to break, and improve the defoaming efficiency.
[0023] 2. The drive assembly rotates the connecting rod, which in turn drives the stirring rod to defoam the air bubbles inside the adhesive. Considering that some small air bubbles cannot be eliminated by the stirring rod, multiple evenly distributed bubble-piercing rods are set on both sides of the stirring rod. The small contact area at the front end of the bubble-piercing rods is used to clean the air bubbles inside the adhesive. At the same time, the scraper on the side of the stirring rod adheres to the inner wall of the defoaming chamber. As the stirring rod rotates, it also drives the scraper to clean the inner wall of the defoaming chamber, preventing air bubbles inside the adhesive from adhering to the inner wall of the defoaming chamber and affecting the overall defoaming efficiency.
[0024] 3. The drive motor rotates, which in turn drives the transmission column to rotate, thereby driving the defoaming component to rotate. At the same time, the hydraulic column at the bottom of the baffle pushes the support plate to facilitate the up and down movement of the drive motor. When the hydraulic column pushes the support plate downward, the drive motor may experience slight displacement due to various reasons. The first elastic element can compensate for these displacements through its own elastic deformation, keeping the motor in a relatively stable position. Attached Figure Description

[0039] The following combination Figures 1-7 This utility model is described in further detail.
[0040] This embodiment discloses a defoaming device for post-treatment of water-based adhesives: including a defoaming tank 1, with multiple support legs 11 fixedly connected to the four feet at the bottom of the defoaming tank 1, a through hole 14 opened at the top of the defoaming tank 1 near the center, a sealing ring 15 fixedly connected inside the through hole, a driving component 2 slidably connected inside the sealing ring 15, a defoaming chamber 12 opened inside the defoaming tank 1, and a defoaming component 3 disposed inside the defoaming chamber 12.
[0041] Please see Figures 1 to 4 The drive assembly 2 includes a drive motor 21. A transmission rod 22 is fixedly connected to the output end of the drive motor 21. A connecting column 311 is fixedly connected to the end of the transmission rod 22 away from the drive motor 21. A support plate 27 is fixedly connected to the end of the drive motor 21 away from the transmission rod 22. Two guide columns 23 are slidably connected inside both ends of the support plate 27. A first elastic element 24 is provided on the outer side of the guide column 23. The support plate 27 is fixedly connected to one end of the first elastic element 24. The defoaming tank 1 is fixedly connected to the other end of the first elastic element away from the support plate 27. A baffle 25 is fixedly connected to the upper end of the guide column 23. A hydraulic column 26 is fixedly connected to the bottom of the baffle 25. The output end of the hydraulic column 26 is fixedly connected to the main support. Plate 27, the defoaming tank 1 has a discharge port 16 near the center of the bottom, a sealing block 17 is snapped into the discharge port 16, the upper surface of the defoaming tank 1 has a feed pipe 13, the outer wall of the feed pipe 13 has a threaded groove 18, the outer wall of the feed pipe 13 is rotatably snapped into a snap ring 42, the inner cavity of the snap ring 42 near the end of the feed pipe 13 is fixedly connected to a threaded ring 43, the threaded ring 43 and the threaded groove 18 are engaged, the end of the snap ring 42 away from the feed pipe 13 is slidably connected to a suction pipe 41, the bottom of the suction pipe 41 is fixedly connected to a sealing gasket 44, the sealing gasket 44 is inside the snap ring 42.
[0042] With this configuration, the drive motor 21 rotates, causing the transmission column 22 to rotate, which in turn rotates the defoaming component 3. Simultaneously, the hydraulic column 26 at the bottom of the baffle 25 pushes the support plate 27, facilitating the up-and-down movement of the drive motor 21. When the hydraulic column 26 pushes the support plate downwards, the drive motor 21 may experience slight displacement due to various reasons. The first elastic element 24 can compensate for these displacements through its own elastic deformation, keeping the drive motor 21 in a relatively stable position. Then, the suction pipe 41 inside the vacuum pump 4 is clamped above the feed pipe 13. By rotating the clamping ring 42, the internal... The threaded ring 43 engages with the threaded groove 18 above the feed pipe 12. Rotating the retaining ring 42 connects the suction pipe 41 to the feed pipe 13. Simultaneously, as the retaining ring 42 drives the suction pipe 41 downward, the feed pipe 13 pushes the sealing gasket 44 to ensure its sealing. The vacuum pump 4 extracts the gas inside the defoaming tank 1 through the suction pipe 41, so that the bubbles inside the adhesive in the defoaming tank 1 are eliminated under negative pressure. After the bubbles inside the adhesive are eliminated, the vacuum pump 4 stops working and the retaining ring 42 is turned to disengage the feed pipe 13 from the retaining ring 42, so that the inside of the defoaming tank 1 returns to normal pressure and avoids secondary foaming.
[0043] Please see Figures 5 to 7 The defoaming component 3 includes a pressurizing assembly 31 and a stirring assembly 32. The pressurizing assembly 31 includes a connecting column 311, with a rotating cavity 313 inside the connecting column 311. A DC motor 312 is fixedly connected inside the rotating cavity 313. A drive gear 314 is fixedly connected to the output end of the DC motor 312. Multiple transmission gears 315 are meshed and rotatably connected to the outer side of the drive gear 314. A driven column 316 is fixedly connected to the end of the transmission gear 315 away from the drive gear 314. A fan blade 317 is fixedly connected to the end of the driven column 316 away from the transmission gear 315. The fan blade 317 is located outside the connecting column 311. The stirring assembly 32 includes a connecting rod 320, with a connecting column 311 fixedly connected to one end of the connecting rod 320. A sliding ring 325 is slidably connected to the outer wall of the end of the connecting rod 320 away from the connecting column 311. 5. Multiple stirring rods 326 are fixedly connected to the outside. Multiple bubble-piercing rods 328 are provided on both sides of the stirring rods 326. A fixing ring 321 is fixedly connected to the outer side of the connecting rod 320 near the connecting column 311. Multiple support rods 322 are rotatably connected to the notch on the outer side of the fixing ring 321. A sliding groove 327 is provided inside the stirring rod 326. A clamping block 323 is slidably connected inside the sliding groove 327. The end of the support rod 322 away from the fixing ring 321 is rotatably connected to the clamping block 323. A second elastic element 324 is provided on the outer side of the connecting rod 320. One end of the second elastic element 324 abuts against the fixing ring 321. The end of the second elastic element 324 away from the fixing ring 321 abuts against the sliding ring 325. A scraper 329 is rotatably connected to the end of the stirring rod 326 away from the sliding ring 325. One side of the scraper 329 is attached to the inner wall of the defoaming chamber 12.
[0044] With this configuration, the drive motor 21 rotates the connecting rod, which in turn drives the stirring rod 326 to defoam the air bubbles inside the adhesive. The small contact area at the tip of the bubble-piercing rod 328 further cleans the air bubbles. Meanwhile, the sliding ring 325 slides upwards under the pressure of the adhesive, defoaming different layers of the adhesive. When the pressure on the sliding ring 325 decreases, it drives the stirring rod 326 back to its original position to continue defoaming the current layer of adhesive. The buffering effect of the second elastic element 324 prevents the downward pressure from the connecting rod 320 from causing secondary foaming inside the adhesive. Simultaneously, the scraper 329 on the side of the stirring rod 326 adheres to the inner wall of the defoaming chamber 12, and its rotation also drives the scraper... The wiping plate 329 cleans the inner wall of the defoaming chamber 12 to prevent air bubbles inside the adhesive from adhering to the inner wall of the defoaming chamber 12. Then, the DC motor 312 inside the connecting column 311 rotates, driving the drive gear 314 to rotate. The drive gear 314 drives the transmission gear 315 on the side to rotate, so that the fan blade 317 on the outside of the connecting column 311 can rotate longitudinally while following the horizontal rotation of the connecting column 311. The longitudinally rotating fan blade 317 will generate shearing and impact on the surface foam layer, increasing the internal pressure of the adhesive and making the foam easier to break. At the same time, the longitudinally rotating fan blade 317 can push the upper layer of adhesive downward and lift the lower layer of adhesive upward, so that the adhesive at different heights can be better mixed for defoaming and improve the defoaming efficiency.
[0045] The implementation principle of the defoaming device for post-treatment of water-based adhesives in this application embodiment is as follows: The drive motor 21 rotates, causing the transmission rod 22 to drive the connecting rod 320 to rotate. Simultaneously, the sliding ring 325 drives the stirring rod 326 to defoam the air bubbles inside the adhesive. At this time, the sliding ring 325 slides upwards under the pressure inside the adhesive, defoaming different layers of the adhesive. When the pressure on the sliding ring 325 decreases, the sliding ring 325 drives the stirring rod 326 back to its original position to continue eliminating air bubbles in the current layer of adhesive. The buffering effect of the second elastic element 324 prevents the pressure generated by the vertical downward movement of the connecting rod 320 from causing secondary foaming inside the adhesive. Furthermore, the scraper 329 on the side of the stirring rod 326 adheres to the inner wall of the defoaming chamber 12. Simultaneously with the rotation of the stirring rod 326, the scraper 329 also drives the defoaming chamber 12 to defoam. 2. The inner wall is cleaned. Finally, the DC motor 312 inside the connecting column 311 is turned, which drives the drive gear 314 to rotate. The drive gear 314 drives the transmission gear 315 on the side to rotate, so that the fan blade 317 on the outside of the connecting column 311 can rotate longitudinally while following the horizontal rotation of the connecting column 311. The longitudinally rotating fan blade 317 will generate shearing and impact on the surface foam layer, increase the internal pressure of the adhesive, make the foam easier to break, and improve the defoaming efficiency. Finally, the vacuum pump 4 is used to extract the gas inside the defoaming tank 1, so that the bubbles inside the adhesive inside the defoaming tank 1 are eliminated under negative pressure. When the bubbles inside the adhesive are eliminated, the vacuum pump 4 stops working and the locking ring 42 is turned to disengage the feed pipe 13 from the locking ring 42, so that the inside of the defoaming tank 1 returns to normal pressure.
