Description

Technical Field

[0001] This utility model relates to the field of defoaming equipment technology, and in particular to a defoaming equipment for water-based coatings. Background Technology

[0002] Defoaming equipment is a specialized device used to eliminate or suppress air bubbles in liquids in industrial production, scientific research experiments, and daily life. The core function of defoaming equipment is to use physical, chemical, or mechanical means to eliminate or suppress air bubbles in liquids. Defoaming equipment can be applied to the defoaming process of water-based coatings, thereby ensuring that the quality of water-based coating products, construction effects, and the final coating meet the design standards.

[0003] Chinese utility model patent CN222969252U discloses a defoaming device for water-based coatings, comprising a first treatment tank, a second treatment tank installed at the bottom of the first treatment tank, and a feeding pipe installed at the top of the first treatment tank. An infusion valve is fitted onto one side of the bottom of the second treatment tank. A transition sealing structure is provided between the bottom of the first treatment tank and the top of the second treatment tank. Two symmetrical bubble-cutting plates are fitted onto the inner side of the first treatment tank. This utility model uses the first treatment tank, second treatment tank, infusion valve, and transition sealing structure to form the main body of the defoaming device. The two bubble-cutting plates, two transmission cranks, two straight gear plates, a gear assembly, and a second electric push rod form an automatic bubble-cutting mechanism. Ultrasonic generators are installed on both sides of the first treatment tank.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned equipment, the operator uses a bubble-cutting plate and an ultrasonic generator to defoam the water-based coating. However, if different types of water-based coatings need to be processed, the density or size of the generated bubbles will be different. In the above-mentioned equipment, the bubble-cutting plate needs to be removed from the transmission crank, which is connected to the gear assembly, making the operation rather cumbersome. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a defoaming device for water-based coatings.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water-based coating defoaming device, including a processing box, an inlet and an outlet are provided through the side wall of the processing box, two magnetic strips are provided inside the processing box, the two magnetic strips are respectively located on both sides of the processing box, a U-shaped rod is also provided inside the processing box to magnetically attract the magnetic strips, a crossbar is provided at the top of the U-shaped rod, a cutting mesh for cutting bubbles in the water-based coating is provided in the frame formed by the crossbar and the U-shaped rod, and a drive mechanism is provided on the processing box to drive the crossbar to reciprocate for defoaming treatment.

[0007] By adopting the above technical solution, when workers need to defoam water-based coatings, they first place the frame inside the processing box, then magnetically attach the U-shaped rod inside the frame to the two magnetic strips, thus fixing the cutting mesh inside the processing box. Workers control the drive mechanism to drive the crossbar to reciprocate, causing the crossbar to move the cutting mesh back and forth to defoam the water-based coating. When the cutting mesh needs to be disassembled to adapt to different types of water-based coatings, workers rotate the crossbar, causing it to move the U-shaped rod to overcome the magnetic strips, allowing them to lift the cutting mesh and complete the disassembly. This application changes the traditional method of removing the transmission crank and gear assembly, simplifying the subsequent steps for replacing the cutting mesh and improving installation efficiency.

[0008] Furthermore, the two opposite sides of the U-shaped rod abut against the inner walls of the processing box on both sides. The driving mechanism includes a transmission assembly, which includes a limiting rod fixed inside the processing box, a fixing block sleeved on the limiting rod and slidably engaged with it, and a transmission rod fixed to the top of the crossbar. The limiting rod is perpendicular to the cutting mesh, and the bottom of the fixing block is fixed to the upper end of the magnetic strip. Two limiting rods and two fixing blocks are provided and located on both sides of the processing box. The driving mechanism also includes a driving assembly for driving the transmission rod to move in a direction parallel to the limiting rod.

[0009] By adopting the above technical solution, the staff can control the drive component to drive the transmission rod to move in a direction parallel to the limit rod, thereby causing the transmission rod to drive the crossbar and U-shaped rod to reciprocate, which in turn drives the cutting mesh to reciprocate in a direction parallel to the limit rod to defoam the water-based coating.

[0010] Furthermore, the drive assembly includes a reciprocating screw rotatably mounted on the inner wall of the processing box and parallel to the limiting rod, a sliding block slidably sleeved on the reciprocating screw and threadedly connected to the reciprocating screw, and a drive motor fixed to the side wall of the processing box and driving the reciprocating screw to rotate. The bottom of the sliding block abuts against the top of the crossbar. A through groove is provided on the sliding block for the transmission rod to pass through. The extension direction of the through groove is perpendicular to the axial direction of the limiting rod. The two sides of the transmission rod are respectively attached to the inner walls on both sides of the through groove. The reciprocating screw passes through the side wall of the processing box near the drive motor and is fixed to the output end of the drive motor.

[0011] By adopting the above technical solution, after the operator starts the drive motor, the drive motor works and drives the reciprocating screw fixed to it to rotate. Since the sliding block is threadedly connected to the reciprocating screw, the transmission rod at the top of the crossbar abuts against the through groove on the sliding block, the bottom of the sliding block abuts against the top of the crossbar, and the U-shaped rod is magnetically attracted to the magnetic strip. This causes the sliding block to drive the transmission rod to move, and the transmission rod drives the crossbar, the U-shaped rod, and the magnetic strip to reciprocate, thereby driving the cutting mesh to reciprocate to defoam the water-based coating. When the operator needs to change the cutting mesh to defoam different types of water-based coatings, the operator only needs to rotate the crossbar to make the U-shaped rod overcome the attraction of the magnetic strip, and then move the crossbar to make the transmission rod move and disengage from the through groove. Lifting the frame completes the overall disassembly of the cutting mesh.

[0012] Furthermore, a bellows is fitted onto the reciprocating lead screw. Two bellows are provided. The ends of the two bellows that are close to each other are fixed to the side walls on both sides of the sliding block, and the ends of the two bellows that are far apart from each other are fixed to the inner walls on both sides of the processing box.

[0013] By adopting the above technical solution, the corrugated pipe reduces the probability of water-based coatings being agitated onto the reciprocating screw and causing damage to the reciprocating screw, thus ensuring the transmission effect between the reciprocating screw and the sliding block.

[0014] Furthermore, a bolt with clearance fit is provided through the crossbar, and the bolt is threaded to the end of the U-shaped bar.

[0015] By adopting the above technical solution, when the cutting mesh needs to be cleaned or replaced, workers can easily loosen the bolts using tools to disassemble it. When workers need to install the cutting mesh, the process is reversed to complete the installation.

[0016] Furthermore, a feed hopper communicating with the feed inlet is provided on the side wall of the processing box.

[0017] By adopting the above technical solution, the feeding hopper is designed to facilitate workers to quickly add water-based coatings into the treatment tank.

[0018] Furthermore, a first annular rubber pad is attached and fixed to the top of the feed hopper, and a cover plate for closing the feed hopper opening is provided on the side wall of the feed hopper near its top.

[0019] By adopting the above technical solution, after the staff adds the water-based coating into the treatment tank through the feed hopper, they close the cover plate. The cover plate cooperates with the feed hopper and presses the first annular rubber gasket, ensuring the airtightness of the feed hopper and preventing other air and debris from entering the treatment tank during the cutting process, thus ensuring the quality of the water-based coating.

[0020] Furthermore, a second annular rubber pad is attached and fixed to the top of the processing box, and a sealing plate is hinged to the side wall of the processing box near its top. The bottom of the sealing plate engages with the top of the processing box and abuts against the second annular rubber pad.

[0021] By adopting the above technical solution, the second annular rubber pad is made of rubber, which has a certain degree of flexibility and resilience. After the staff closes the sealing plate, the sealing plate cooperates with the treatment box and presses the second annular rubber pad tightly, preventing other air and debris from entering the treatment box, thus further ensuring the quality of water-based coatings.

[0022] In summary, this utility model has the following beneficial effects: When workers need to defoam water-based coatings, they first place the frame inside the processing box, then magnetically attach the U-shaped rod in the frame to the two magnetic strips, thus fixing the cutting mesh inside the processing box. Workers control the drive mechanism to drive the crossbar to reciprocate, thereby causing the crossbar to move the cutting mesh back and forth to defoam the water-based coating. When it is necessary to disassemble the cutting mesh to adapt to different types of water-based coatings, workers rotate the crossbar, causing the crossbar to move the U-shaped rod to overcome the attraction of the magnetic strips, and then workers can lift the cutting mesh to complete the overall disassembly.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-6 As shown in the illustration, this application discloses a water-based coating defoaming device, including a treatment box 1, magnetic strips 13, a frame 2, and a drive mechanism 3. A feed inlet 11 and a discharge outlet 12 are provided through the side wall of the treatment box 1. Two magnetic strips 13 are disposed inside the treatment box 1, located on opposite sides of the treatment box 1. The frame 2 includes a U-shaped rod 21 and a crossbar 22. The U-shaped rod 21 is disposed inside the treatment box 1 and magnetically attracted to the magnetic strips 13. The cross-section of the U-shaped rod 21 is U-shaped, and the two opposite sides of the U-shaped rod 21 abut against the inner walls of the two sides of the treatment box 1. The crossbar 22 is disposed at the top of the U-shaped rod 21, and the crossbar 22 and the U-shaped rod 21 form the frame 2 structure. A cutting mesh 23 is provided inside the frame 2. The bottom of the crossbar 22 and the inner side of the U-shaped bar 21 are provided with slots (not shown in the figure) that engage with the cutting mesh 23. The cutting mesh 23 is used to cut air bubbles in water-based coatings.

[0032] A drive mechanism 3 is mounted on the processing box 1 and is used to drive the crossbar 22 to reciprocate for defoaming treatment. The drive mechanism 3 includes a transmission assembly 31 and a drive assembly 32. The transmission assembly 31 includes a limiting rod 311, a fixing block 312, and a transmission rod 313. The limiting rod 311 is fixed inside the processing box 1, and the fixing block 312 is sleeved on the limiting rod 311 and slidably engaged with it. In this embodiment, the bottom of the fixing block 312 is fixed to the upper end of the magnetic strip 13, and two limiting rods 311 and two fixing blocks 312 are provided and located on both sides of the processing box 1 respectively. The transmission rod 313 is fixed to the top of the crossbar 22, and the limiting rod 311 is perpendicular to the cutting mesh 23.

[0033] The drive assembly 32 is used to drive the transmission rod 313 to move in a direction parallel to the limit rod 311. The drive assembly 32 includes a reciprocating screw 321, a sliding block 322, and a drive motor 323. The reciprocating screw 321 is rotatably mounted on the inner wall of the processing box 1 and is parallel to the limit rod 311. The sliding block 322 is slidably sleeved on the reciprocating screw 321 and threadedly connected to the reciprocating screw 321. The bottom of the sliding block 322 abuts against the top of the crossbar 22. The drive motor 323 is fixed to the side wall of the processing box 1 and drives the reciprocating screw 321 to rotate. The axis of the output shaft of the drive motor 323 coincides with the axis of the reciprocating screw 321. A through groove 3221 is provided on the sliding block 322 for the transmission rod 313 to pass through. The extension direction of the through groove 3221 is perpendicular to the axial direction of the limiting rod 311. In this embodiment, the two sides of the transmission rod 313 are respectively attached to the inner walls of the two sides of the through groove 3221. The reciprocating screw 321 passes through the side wall of the processing box 1 near the drive motor 323 and is fixed to the output end of the drive motor 323.

[0034] When workers need to defoam water-based coatings, they first place the frame 2 inside the processing box 1, then move the transmission rod 313 into the through groove 3221, rotate the frame 2, and magnetically attract the U-shaped rod 21 inside the frame 2 to the two magnetic strips 13, thereby fixing the cutting mesh 23 inside the processing box 1. After the workers start the drive motor 323, the drive motor 323 works and drives the reciprocating screw 321 fixed to it to rotate. Due to the sliding block 322 and the reciprocating screw... The lever 321 is threaded, and the transmission rod 313 at the top of the crossbar 22 abuts against the through groove 3221 on the sliding block 322. The bottom of the sliding block 322 abuts against the top of the crossbar 22, and the U-shaped rod 21 is magnetically attracted to the magnetic strip 13. This causes the sliding block 322 to drive the transmission rod 313 to move, and the transmission rod 313 drives the crossbar 22, the U-shaped rod 21, and the magnetic strip 13 to reciprocate, thereby driving the cutting mesh 23 to reciprocate to defoam the water-based coating. When the operator needs to disassemble the frame 2, the operation is reversed to complete the disassembly of the frame 2.

[0035] In this embodiment, two bellows 4 are fitted onto the reciprocating screw 321. The ends of the two bellows 4 that are close to each other are fixed to the side walls on both sides of the sliding block 322, while the ends of the two bellows 4 that are far apart are fixed to the inner walls on both sides of the processing box 1. The bellows 4 reduce the probability of water-based paint splashing onto the reciprocating screw 321 and causing damage, thus ensuring the transmission effect between the reciprocating screw 321 and the sliding block 322.

[0036] In this embodiment, a bolt 5 with a clearance fit is provided through the crossbar 22, and the bolt 5 is threadedly connected to the end of the U-shaped bar 21. When the cutting mesh 23 needs to be cleaned or replaced, the operator can loosen the bolt 5 with a tool to remove the cutting mesh 23. When the operator needs to install the cutting mesh 23, the operation is reversed to complete the installation of the cutting mesh 23.

[0037] In this embodiment, a feed hopper 6 communicating with the feed inlet 11 is provided on the side wall of the treatment tank 1. The feed hopper 6 facilitates the quick addition of water-based coatings into the treatment tank 1 by the operator.

[0038] In this embodiment, a first annular rubber pad 7 is attached and fixed to the top of the hopper, and a cover plate 8 for sealing the opening of the hopper 6 is provided on the side wall near its top. After the operator adds water-based paint to the treatment tank 1 through the hopper 6, the cover plate 8 is closed. The cover plate 8 cooperates with the hopper 6 and presses the first annular rubber pad 7, ensuring the airtightness of the hopper 6 and preventing other air and debris from entering the treatment tank 1 during the cutting process of the cutting mesh 23, thus ensuring the quality of the water-based paint.

[0039] In this embodiment, a second annular rubber pad 9 is attached and fixed to the top of the treatment box 1. A sealing plate 14 is hinged to the side wall of the treatment box 1 near its top. The bottom of the sealing plate 14 engages with the top of the treatment box 1 and presses against the second annular rubber pad 9. The second annular rubber pad 9 is made of rubber and has a certain degree of flexibility and resilience. After the operator closes the sealing plate 14, the sealing plate 14 engages with the treatment box 1 and presses against the second annular rubber pad 9, preventing other air and debris from entering the treatment box 1, thus further ensuring the quality of the water-based coating.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected.
