Description
Technical Field
[0001] This invention relates to the field of resin processing technology, and in particular to a bubble elimination device and processing method for resin processing. Background Technology
[0002] A bubble removal device for resin processing refers to a specialized device used during resin mixing, conveying, or molding to remove gases (mainly air and volatile components from the reaction) mixed into the resin, in order to prevent defects such as bubbles and pores from forming in the final product.
[0003] Traditional equipment typically employs open-type or high-level drip feeding structures. During the feeding process, the material impacts the liquid surface from a height, easily entraining air and forming new bubbles. Defoaming and foaming occur simultaneously, significantly reducing defoaming efficiency. Defoaming methods are limited and incomplete. Furthermore, vacuum defoamers can only cause bubbles to expand and float through negative pressure, which is extremely ineffective at handling micron-sized bubbles in high-viscosity resins. Centrifugal defoamers rely on centrifugal force to separate large bubbles but cannot break down tiny bubbles. Additionally, the discharge pipe lacks insulation, causing resin to easily adhere and contaminate new raw materials.
[0004] Therefore, this application provides a bubble elimination device and processing method for resin processing to meet the requirements. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a bubble elimination device and processing method for resin processing, so as to solve the problem that when materials impact the liquid surface from a height during the feeding process, they are prone to entraining air and forming new bubbles, and the defoaming method is singular and the defoaming is incomplete.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A bubble-eliminating device for resin processing includes a defoaming device body. A motor is installed on one side of the internal structure of the defoaming device body, and a belt mechanism is installed at the output end of the motor. A rotating shaft is installed on the other side of the belt mechanism. A fixed seat is fixedly connected to the outer wall of the top of the rotating shaft. A gas-hydraulic-electric combined slip ring is installed at the bottom of the rotating shaft, and the stator at the bottom of the gas-hydraulic-electric combined slip ring is fixedly connected to the inner wall of the bottom of the defoaming device body. A feeding assembly is provided at the top of the fixed seat for introducing material. Several defoaming components are provided on the outer side of the feeding assembly for eliminating bubbles inside the material. A discharge assembly is provided at the bottom of each of the defoaming components for discharging the defoamed material.
[0007] Optionally, the feeding assembly includes a first electric telescopic rod, which is installed at the center of the top of the fixed base. The output end of the first electric telescopic rod is fixedly connected to a connecting seat, and a slide rod is slidably connected to the inner wall of the center of the top of the connecting seat.
[0008] Optionally, the feeding assembly further includes a rotary joint, which is installed at the top of the slide bar. The top of the rotary joint is connected to a feeding pipe, which penetrates the top outer wall of the defoaming device body and is fixedly connected thereto. A feeding valve is installed inside the feeding pipe.
[0009] Optionally, the feeding assembly further includes a plurality of first guide tubes, each of which is connected to the bottom end of the rotary joint. The bottom outer walls of the plurality of first guide tubes are slidably connected to connecting tubes, and the outer wall of each connecting tube is fixedly connected to a connecting cap. The bottom outer wall of each connecting cap is connected to a first corrugated pipe.
[0010] Optionally, the defoaming component includes a tank body connected to the other end of the first corrugated pipe. Rotating rods are fixedly connected to both sides of the top of the tank body, and support rods are rotatably connected to the other ends of the two rotating rods. The two support rods are fixedly connected to the top outer wall of the fixed base. A second electric telescopic rod is provided on one side of the tank body. The bottom end of the second electric telescopic rod is hinged to the outer wall of the fixed base, and the output end of the second electric telescopic rod is fixedly connected to the rotating rod on one side.
[0011] Optionally, the defoaming component further includes a heating ring embedded in the inner wall of the tank, and an ultrasonic vibrating rod fixedly connected to the bottom of the tank. The ultrasonic vibrating rod penetrates the outer wall of the bottom of the tank and is fixedly connected to a transducer.
[0012] Optionally, the discharge assembly includes a first discharge pipe connected to the center of the bottom end of the tank, and a first discharge valve is installed inside the first discharge pipe.
[0013] Optionally, the discharge assembly further includes a second corrugated pipe, which is connected to the other end of the first discharge pipe. The other end of the second corrugated pipe is connected to a double-layered radish-shaped observation tube. A bracket is fixedly connected to the outside of the double-layered radish-shaped observation tube. The bracket is fixedly connected to the outer wall of the rotating shaft. A camera is fixedly connected to one side of the bottom end of the bracket. A ring-shaped LED supplementary light is provided on one side of the camera. The ring-shaped LED supplementary light is fixedly connected to the bracket. The bottom end of the double-layered radish-shaped observation tube is connected to a second guide pipe. The other end of the second guide pipe is connected to the interface of the gas-liquid-electric combined slip ring.
[0014] Optionally, each of the tanks is internally connected to a corrugated exhaust pipe, and each corrugated exhaust pipe is internally equipped with a first exhaust valve. The other end of each corrugated exhaust pipe is connected to the interface of a gas-hydraulic-electric combined slip ring. The top of one side of the gas-hydraulic-electric combined slip ring is connected to a number of second drain pipes, the number of which is the same as the number of second feed pipes, and they correspond one-to-one. The bottom of one side of the gas-hydraulic-electric combined slip ring is connected to a number of second exhaust pipes, the number of which is the same as the number of corrugated exhaust pipes, and they correspond one-to-one.
[0015] The present invention also provides another technical solution: a processing method for a bubble elimination device for resin processing, the method comprising the following steps: S1: Driven by the output end of the first electric telescopic rod, the connecting cover moves the connecting pipe downward to a position close to the bottom of the tank, and then the feed valve is opened to allow the material to enter the tank. S2: The output end of the second electric telescopic rod drives the tank to rotate to the target angle. Under the drive of the motor, the rotating shaft drives the tank to perform centrifugal motion. The centrifugal force generated by the centrifugal motion defoams the large air bubbles inside the material. S3: While the tank is undergoing centrifugal motion, the heating ring is activated to heat the material, thereby reducing the viscosity of the material. Through the synergistic effect of heating and centrifugal motion, the degassing time is greatly shortened. S4: In the later stage of the centrifugal motion of the tank, the electrical signal of the ultrasonic generator is converted into high-frequency mechanical vibration by the transducer, so that the ultrasonic vibrating rod generates cavitation effect in the material through pulse mode. The local high temperature and high pressure generated when the cavitation bubble collapses can instantly break the micron-sized bubble, making up for the inadequacy of centrifugal force in treating micro bubbles. S5: The vacuum exhaust system is activated throughout the centrifugal motion of the tank, and the gas is discharged through the corrugated exhaust pipe and the second exhaust pipe by the negative pressure generated inside the tank. S6: After defoaming is completed, the first drain valve is opened, and the material is discharged through the first drain pipe, the second corrugated pipe, the double-layer radish-shaped observation cylinder, the second guide pipe, and the second drain pipe. The camera then collects images of the double-layer radish-shaped observation cylinder in real time, and the terminal system performs real-time analysis. When no material flow is detected for several consecutive seconds and there is no residue on the inner wall of the observation cylinder, the control system determines that the discharge is complete.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up an immersion feeding assembly including a first electric telescopic rod, a connecting pipe, and a first corrugated pipe, the feeding is achieved by driving the connecting pipe to move down to below the liquid surface at the bottom of the tank. This avoids the material impacting the liquid surface from a height and drawing in air, thus fundamentally reducing bubble generation. At the same time, the inner wall of the feeding pipe is coated with a PTFE coating, which utilizes its low surface energy characteristics to prevent resin adhesion and prevent adhered materials from forming bubble nuclei, greatly reducing the amount of bubbles generated in the feeding process.
[0017] In the above scheme, four defoaming methods—centrifugal separation, heating to reduce viscosity, ultrasonic cavitation, and vacuum-assisted defoaming—are organically combined to form a synergistic system of coarse defoaming, fine defoaming, and accelerated defoaming. Centrifugal force rapidly separates millimeter-sized large bubbles, while a heating ring precisely controls the temperature through a temperature sensor to reduce resin viscosity. Stokes' law accelerates the bubble's rise, compensating for the shortcomings of centrifugal force in defoaming high-viscosity materials. An ultrasonic vibrating rod generates a cavitation effect in pulse mode, using the local high temperature and pressure of cavitation bubble collapse to break micron-sized microbubbles, solving the problem of poor microbubble treatment in traditional equipment. Finally, a vacuum system actively extracts the separated gas through a corrugated exhaust pipe. The negative pressure causes the bubble volume to expand, further increasing buoyancy and accelerating bubble rise and discharge. Through the synergistic effect of these four methods, the defoaming efficiency is greatly improved and the defoaming time is shortened.
[0018] In the above solution, the tank can be driven to rotate around the rotating rod to any target angle through the cooperation of the second electric telescopic rod, the rotating rod and the support rod. The centrifugal path of the material in the tank can be adjusted according to the viscosity of the resin and the bubble content. For high viscosity resins, the tilt angle of the tank can be increased to extend the centrifugal movement distance of the material and improve the degassing effect. The equipment adaptability is greatly improved compared with the traditional fixed tank equipment, and it can meet the degassing needs of different types of resins such as epoxy resin, polyurethane resin and acrylic resin.
[0019] In the above scheme, the double-layer glass structure of the double-layer radish-shaped observation tube greatly improves the heat preservation effect, slows down the heat loss of the resin, and ensures the fluidity of the material throughout the discharge process. The inner glass layer is at a temperature close to the resin, while the outer glass layer is at room temperature, avoiding fogging caused by temperature difference condensation. Simultaneously, the conical inner wall guides and converges the material, preventing eddies and stagnation zones caused by sudden changes in pipe diameter, thus structurally eliminating secondary foaming during the discharge process. Furthermore, an ultrasonic vibration plate drives the material to vibrate at high frequency, promoting material discharge and reducing material residue. The discharge pipes are coated with PTFE to reduce resin residue and prevent residual material from drying and forming new bubble nuclei. A combination of a camera and a ring-shaped LED supplementary light allows for real-time acquisition of images of material flow and bubble status within the tube, enabling visual monitoring of the defoaming effect through terminal system analysis. During the discharge process, the terminal system automatically determines the discharge completion rate based on image analysis results, and, in conjunction with a weighing sensor, ensures accurate discharge volume.

[0029] like Figures 1 to 8 As shown, an embodiment of the present invention provides a bubble elimination device for resin processing, including a defoaming device body 1. A motor 2 is installed inside one side of the defoaming device body 1. A belt mechanism 3 is installed at the output end of the motor 2. The belt mechanism 3 consists of two pulleys and a transmission belt. A first pulley is fixedly connected to the output end of the motor 2. A transmission belt is connected to the outer wall of the first pulley. The other end of the transmission belt is connected to a second pulley. The center of the second pulley is fixedly connected to the outer wall of a rotating shaft 4. When the output end of the motor 2 rotates, the first pulley rotates, which in turn rotates the transmission belt, which in turn rotates the second pulley, which in turn rotates the rotating shaft 4. This, in turn, rotates the tank 701. The other end of the belt mechanism 3... A rotating shaft 4 is mounted on the side, and a fixed seat 5 is fixedly connected to the outer wall of the top of the rotating shaft 4. A gas-hydraulic-electric combined slip ring 9 is mounted on the bottom of the rotating shaft 4. The stator at the bottom of the gas-hydraulic-electric combined slip ring 9 is fixedly connected to the inner wall of the bottom of the defoaming equipment body 1. The rotor of the gas-hydraulic-electric combined slip ring 9 is fixedly connected to the rotating shaft 4. Cables are installed inside the gas-hydraulic-electric combined slip ring 9. Cables for transducer 705, heating ring 706, camera 807, and ring LED supplement light 808 are all connected through the gas-hydraulic-electric combined slip ring 9. A feeding component 6 is set at the top of the fixed seat 5. The feeding component 6 is used to introduce materials. Several defoaming components 7 are set on the outside of the feeding component 6. The several defoaming components 7 are used to eliminate bubbles inside the materials. A discharge component 8 is set at the bottom of each of the several defoaming components 7. The discharge component 8 is used to discharge the defoamed materials.
[0030] like Figures 2 to 8As shown, the feeding assembly 6 includes a first electric telescopic rod 601, which is installed at the center of the top of the fixed base 5. A connecting base 602 is fixedly connected to the output end of the first electric telescopic rod 601. A sliding rod 603 is slidably connected to the inner wall of the center of the top of the connecting base 602. Several sliders are fixedly connected to the outer wall of the bottom end of the sliding rod 603. Several grooves corresponding to the sliders are opened inside the connecting base 602, allowing the connecting base 602 to slide axially. The feeding assembly 6 also includes a rotary joint 604. The stator of the rotary joint 604 is fixedly connected to the feeding pipe 605, and the rotor of the rotary joint 604 is fixedly connected to the sliding rod 603. The rotary joint 604 is installed at the top of the sliding rod 603, and the top of the rotary joint 604 is connected to the feeding pipe 605. The feeding pipe 605 is a rigid pipe used to fix the housing of the rotary joint 604. The feeding pipe 605 has a through-hole defoaming device. The top outer wall of the main body 1 is fixedly connected to it. The feed valve 606 is installed inside the feed pipe 605. The feed assembly 6 also includes several first guide pipes 607. The several first guide pipes 607 are all connected to the bottom end of the rotary joint 604. The bottom outer wall of the several first guide pipes 607 is slidably connected to the connecting pipe 608. The inner wall of the first guide pipe 607 and the connecting pipe 608 slide against each other. When the connecting pipe 608 moves downward, the connecting pipe 608 slides relative to the first guide pipe 607, so as to facilitate the connecting pipe 608 to move to the bottom end of the tank 701. The outer wall of each connecting pipe 608 is fixedly connected to the connecting cover 609. The bottom outer wall of each connecting cover 609 is connected to the first corrugated pipe 610. The inner walls of the feed pipe 605, the first guide pipe 607, the connecting pipe 608 and the first corrugated pipe 610 are all sprayed with PTFE coating to prevent the resin from sticking during the introduction process.
[0031] like Figures 3 to 8As shown, the defoaming component 7 includes a tank 701, which is connected to the other end of the first corrugated pipe 610. Rotating rods 702 are fixedly connected to both sides of the top of the tank 701. Support rods 703 are rotatably connected to the other ends of the two rotating rods 702. The support rods 703 are used to limit the movement of the rotating rods 702 and support the tank 701. Both support rods 703 are fixedly connected to the outer wall of the top of the fixed base 5. A second electric telescopic rod 704 is provided on one side of the tank 701. The bottom end of the second electric telescopic rod 704 is hinged to the outer wall of the fixed base 5. The output end of the second electric telescopic rod 704 is fixedly connected to one of the rotating rods 702. The defoaming component 7 also includes... The device includes a heating ring 706, inside which a temperature sensor is installed for monitoring the temperature of the material. The heating ring 706 is coated with a PTFE coating and has a temperature sensor installed on its inner wall, allowing for real-time monitoring of the material's heating temperature and effective control of the material within a safe heating temperature range. The heating ring 706 is embedded in the inner wall of the tank body 701. An ultrasonic vibrating rod 707 is fixedly connected to the bottom of the tank body 701. The ultrasonic vibrating rod 707 penetrates the bottom outer wall of the tank body 701 and is fixedly connected to a transducer 705. The cable of the transducer 705 is connected to the ultrasonic generator through a gas-liquid-electric combined slip ring 9.
[0032] like Figures 2 to 7As shown, the discharge assembly 8 includes a first drain pipe 801, which is connected to the center of the bottom end of the tank 701. A first drain valve 802 is installed inside the first drain pipe 801. The discharge assembly 8 also includes a second corrugated pipe 803, which is connected to the other end of the first drain pipe 801. The other end of the second corrugated pipe 803 is connected to a double-layered radish-shaped observation tube 804. The double-layered radish-shaped observation tube 804 is equipped with double-layered glass, which has a good heat preservation effect and can effectively reduce heat loss, so that the resin maintains good fluidity throughout the discharge process. The inner layer of the double-layered structure... The glass temperature is closer to that of the resin, and the outer glass temperature is close to room temperature, effectively avoiding fogging caused by condensation or temperature differences, ensuring that the camera 807 can always capture a clear image. Meanwhile, the conical inner wall of the double-layered radish-shaped observation tube 804 guides and converges the flowing resin, preventing eddies or stagnant areas caused by sudden changes in pipe diameter, thus preventing the re-entry of air and the formation of new bubbles during the discharge process. A bracket 806 is fixedly connected to the outer side of the double-layered radish-shaped observation tube 804, and the bracket 806 is fixedly connected to the outer wall of the rotating shaft 4. A camera is fixedly connected to one side of the bottom of the bracket 806. A ring-shaped LED fill light 808 is installed on one side of the head 807 and is fixedly connected to the bracket 806. The ring-shaped LED fill light 808 is used to supplement the light source of the camera 807 to avoid the camera 807 capturing unclear images due to dim lighting. The bottom end of the double-layer radish-shaped observation tube 804 is connected to a second guide pipe 805. The other end of the second guide pipe 805 is connected to the interface of the gas-liquid-electric combined slip ring 9. The interior of several tanks 701 is connected to a corrugated exhaust pipe 10. Each corrugated exhaust pipe 10 is equipped with a first exhaust valve 11. The other end of each corrugated exhaust pipe 10 is connected to the interface of the gas-hydraulic-electric combined slip ring 9. The inner walls of the first drain pipe 801, the second corrugated pipe 803, the double-layer radish-shaped observation tube 804, and the second drain pipe 12 are all coated with PTFE coating to reduce resin residue. Several second drain pipes 12 are connected to the top of one side of the gas-hydraulic-electric combined slip ring 9. The number of second drain pipes 12 is the same as that of the second guide pipes 805, and they correspond one-to-one. Several second exhaust pipes 13 are connected to the bottom of one side of the gas-hydraulic-electric combined slip ring 9. The number of second exhaust pipes 13 is the same as that of the corrugated exhaust pipes 10, and they correspond one-to-one.
[0033] The working principle of the technical solution provided by this invention is as follows: During operation, the material pipeline is connected to the feed pipe 605. The first electric telescopic rod 601 is activated, causing the connecting seat 602 to move downwards via its output end. The connecting seat 602 then moves the connecting cover 609 downwards, which in turn moves the connecting pipe 608 downwards. This causes the connecting pipe 608 to move close to the bottom of the tank 701, simultaneously compressing the first bellows 610. When the connecting pipe 608 reaches the bottom of the tank 701, the feed valve 606 is opened, allowing material to enter the feed pipe 605 through the material pipeline. The material then passes through the feed pipe 605... The rotary joint 604 guides the material into the first feed pipe 607, which then guides the material into the connecting pipe 608. The connecting pipe 608 then guides the material into the tank 701, thus achieving submersion feeding. This releases the material below the liquid surface, preventing air from being drawn in by the material impacting the liquid surface from a height, and eliminating the generation of bubbles at the source. After the feeding is completed, the first electric telescopic rod 601 is activated. The output end of the first electric telescopic rod 601 drives the connecting seat 602 to move upward, which in turn drives the connecting cover 609 to move upward, and the connecting cover 609 drives the connecting pipe 608 to reset.
[0034] Furthermore, when defoaming is required, the second electric telescopic rod 704 is activated. The output of the second electric telescopic rod 704 applies a thrust to the rotating rod 702, generating a torque at the rotation center of the rotating rod 702. This torque drives the rotating rod 702 to rotate, which in turn drives the tank 701 to rotate to the target angle. At this point, the heating ring 706 is activated to heat the material inside the tank 701. Simultaneously, the motor 2 is activated, driving the belt mechanism 3 through its output. The belt mechanism 3 drives the rotating shaft 4 to rotate, which in turn drives the fixed seat 5 and the connecting seat 602 to rotate. The fixed seat 5 and the connecting seat 602 simultaneously drive the connecting cover 609 and the tank 701 to rotate. This causes the material inside the tank 701 to undergo centrifugal motion. The centrifugal force generated by this motion defoams large air bubbles inside the material. Simultaneously, the heating ring 706 heats the material, reducing its viscosity. According to Stokes' law, the bubble rising speed is inversely proportional to the liquid viscosity. The reduced viscosity significantly improves the separation efficiency of bubbles in the centrifugal force field. Through the synergistic effect of heating and centrifugal motion, the degassing time is greatly shortened. At this time, the ultrasonic generator is started, and the electrical signal of the ultrasonic generator is converted into high-frequency mechanical vibration through the transducer 705. This causes the ultrasonic vibrating rod 707 to generate a cavitation effect in the material through a pulse mode. The local high temperature and high pressure generated when the cavitation bubbles collapse can instantly break the micron-sized bubbles, making up for the inadequacy of centrifugal force in treating small bubbles. At the same time, the second exhaust pipe 13 is connected to the vacuum exhaust system, the first exhaust valve 11 is opened, and the vacuum exhaust system is started. The separated gas is actively extracted through the vacuum exhaust system. Meanwhile, the negative pressure inside the tank 701 causes the bubble volume to expand and the buoyancy to increase, further accelerating the upward movement. This allows the gas inside the tank 701 to enter the corrugated exhaust pipe 10, which then guides the gas into the second exhaust pipe 13. The second exhaust pipe 13 then vents the gas into the vacuum exhaust system, and finally, the vacuum exhaust system discharges the gas.
[0035] Furthermore, after the material has finished defoaming, motor 2 is turned off, and the second electric telescopic rod 704 is restarted. The output end of the second electric telescopic rod 704 applies a pulling force to the rotating rod 702, thereby generating a reverse torque at the rotation center of the rotating rod 702. This causes the rotating rod 702 to drive the tank 701 to rotate in the opposite direction, thus resetting the tank 701. At this time, the first drain valve 802 is opened, and the material automatically flows into the first drain pipe 801 under the action of gravity. Then, the material is guided into the second corrugated pipe 803 through the first drain pipe 801, and then into the double-layer radish-shaped observation tube 804 through the second corrugated pipe 803. Finally, the material is guided into the second guide pipe 805 through the double-layer radish-shaped observation tube 804, and then into the second drain pipe 12 through the second guide pipe 805. Finally, the material is discharged through the second drain pipe 12.
[0036] In addition, during material discharge, the camera 807 and the ring LED supplement light 808 are turned on simultaneously. The camera 807 collects images of the double-layer radish-shaped observation cylinder 804 in real time, and then performs real-time analysis through the terminal system. When no material flow is detected for several consecutive seconds and there is no residue on the inner wall of the observation cylinder, the control system determines that the material discharge is complete and closes the first discharge valve 802.

10. A method of using a bubble-removing device for resin processing, applicable to the bubble-removing device for resin processing as described in claim 9, characterized in that, The method includes the following steps: S1: Driven by the output end of the first electric telescopic rod, the connecting cover moves the connecting pipe downward to a position close to the bottom of the tank, and then the feed valve is opened to allow the material to enter the tank. S2: The output end of the second electric telescopic rod drives the tank to rotate to the target angle. Under the drive of the motor, the rotating shaft drives the tank to perform centrifugal motion. The centrifugal force generated by the centrifugal motion defoams the large air bubbles inside the material. S3: While the tank is undergoing centrifugal motion, the heating ring is activated to heat the material, thereby reducing the viscosity of the material. Through the synergistic effect of heating and centrifugal motion, the degassing time is significantly shortened. S4: In the later stage of the centrifugal motion of the tank, the electrical signal of the ultrasonic generator is converted into high-frequency mechanical vibration by the transducer, so that the ultrasonic vibrating rod generates cavitation effect in the material through pulse mode. The local high temperature and high pressure generated when the cavitation bubble collapses can instantly break the micron-sized bubble, making up for the inadequacy of centrifugal force in treating micro bubbles. S5: The vacuum exhaust system is activated throughout the centrifugal motion of the tank, and the gas is discharged through the corrugated exhaust pipe and the second exhaust pipe by the negative pressure generated inside the tank. S6: After defoaming is completed, the first drain valve is opened, and the material is discharged through the first drain pipe, the second corrugated pipe, the double-layer radish-shaped observation cylinder, the second guide pipe, and the second drain pipe. The camera then collects images of the double-layer radish-shaped observation cylinder in real time, and the terminal system performs real-time analysis. When no material flow is detected for several consecutive seconds and there is no residue on the inner wall of the observation cylinder, the control system determines that the discharge is complete.
