Description

Technical Field

[0001] This application relates to the field of electrophoretic coating technology, specifically to an intelligent and environmentally friendly electrophoretic coating equipment. Background Technology

[0002] Electro-coating is a coating method that uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit onto the surface of a substrate, which is one of the electrodes. Developed over the past 30 years, electro-coating is a specialized film-forming method and is the most practically significant application process for water-based coatings. It features water solubility, non-toxicity, and ease of automation, and has rapidly gained widespread application in industries such as automotive, building materials, hardware, and home appliances.

[0003] Chinese patent document CN220361667U discloses a rinsing device after cathodic electrophoretic coating, specifically disclosing a spray chamber and a conveyor belt. The conveyor belt is installed inside the spray chamber, and several perforations are opened on its circumferential side. A water tank is installed on the upper surface of the spray chamber, and a drive frame is fixedly connected to the bottom surface of the spray chamber. Two sets of connecting shafts are rotatably connected to one surface of the drive frame, and a first conduit is installed at one end of each connecting shaft. A first connecting pipe connects the water tank and the first conduit. Second connecting pipes are connected to opposite side walls of the water tank, and one end of each second connecting pipe is connected to a second conduit. This patent, by setting up a water tank, a first conduit, a second conduit, a first connecting pipe, and a second connecting pipe, ensures the rinsing range by using the first conduit and nozzles to rinse the top and periphery of the blank, and the second conduit and nozzles to rinse the bottom and periphery of the blank, thus avoiding rinsing dead corners and making the blank cleaner more thorough.

[0004] In the aforementioned patent, the workpiece is conveyed by a transmission belt, and there will inevitably be a part of the workpiece and the transmission belt in contact with each other. This part is difficult to clean. At the same time, the water sprayed from the nozzle can easily splash out to the outside of the spray chamber, thereby polluting the operating environment.

[0019] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] like Figure 1-2 As shown, the intelligent and environmentally friendly electrophoretic coating equipment includes a housing 1 and a conveyor chain 2 running through the housing 1. The housing 1 is a square tube extending from left to right. One end of the conveyor chain 2 is located on the left side of the housing 1, and the other end of the conveyor chain 2 is located on the right side of the housing 1. The part of the conveyor chain 2 inside the housing 1 contacts the top of the housing 1. Several lifting devices 3 are provided on the conveyor chain 2. A rinsing mechanism 4 is provided on the inner side of the middle part of the housing 1. The lifting devices 3 are used to lift the workpiece to be rinsed, and the conveyor chain 2 is used to transport the workpiece through the rinsing mechanism 4. The rinsing mechanism 4 is used to rinse the workpiece. An air jet ring is provided on the inner side of both ends of the housing 1. The air jet ring includes several air jet nozzles 10. The air jet nozzles 10 spray gas toward the axis of the housing 1 and form an air curtain.

[0021] Several lifting devices 3 are sequentially conveyed into the inner side of the housing 1 by the conveyor chain 2 and passed through the rinsing mechanism 4, thereby rinsing the workpiece. During the rinsing process, the air nozzles 10 maintain an airflow state, thus forming two air curtains on the inner sides of both ends of the housing 1, preventing wastewater generated during the rinsing operation from drifting to the outside of the housing 1, effectively protecting the operating environment. Furthermore, as the workpiece passes through the two air curtains, dust and water stains on its surface can be reliably removed, improving the cleanliness of the workpiece.

[0022] The conveying direction of the conveyor chain 2 is parallel to the length direction of the housing 1. When the lifting device 3 is located inside the flushing mechanism 4, the conveyor chain 2 is in the closed state and the flushing mechanism 4 is in the open state. In this way, the flushing mechanism 4 has enough time to reliably flush the workpiece on each lifting device 3.

[0023] The rinsing mechanism 4 includes a bracket 41, a base plate 42, and a motor 43. The motor 43 is located on the outer side of the middle part of the housing 1, and the output shaft of the motor 43 passes through the inner side of the housing 1. The base plate 42 and the bracket 41 are located on the inner side of the middle part of the housing 1. The base plate 42 is mounted on the output shaft of the motor 43. The bracket 41 is fixedly mounted on the top of the base plate 42. The bracket 41 is U-shaped, and several water spray heads 410 are provided on the inner wall of the bracket 41. The motor 43 is used to drive the base plate 42 and the bracket 41 to rotate, and the water spray heads 410 are used to spray water toward the workpiece.

[0024] In the initial state, the motor 43 is in standby mode and the end face of the bracket 41 faces the hanger 3. In this way, the workpiece can be reliably moved to the inside of the bracket 41. At this time, the motor 43 starts to drive the base plate 42 to rotate, so that the bracket 41 can rotate around the workpiece. This allows the water spray nozzles on the bracket 41 to spray water more evenly onto the surface of the workpiece, thus rinsing the workpiece.

[0025] The horizontal end of the bracket 41 is connected to the base plate 42. Several water spray heads 410 are provided on both vertical ends of the bracket 41. The several water spray heads 410 on the same vertical end are arranged at equal intervals, and the several water spray heads 410 on two adjacent vertical ends are staggered. That is to say, the water spray heads 410 are arranged more closely along the vertical direction. In this way, the several water spray heads 410 rotate at the same time and spray water in the direction of the axis of the bracket 41, thereby improving the uniformity of water spraying and significantly improving the rinsing effect.

[0026] The lifting device 3 includes a connecting part 31 and a hanging part 32. The connecting part 31 is located on the conveyor chain 2 and is used to connect to the hanging part 32, which is used to hang the workpiece. The connecting part 31 has a cavity 311, and an electric rotating shaft 312 is located inside the cavity 311. A pull rope 313 is wound on the electric rotating shaft 312. One end of the pull rope 313 is located inside the cavity 311, and the other end of the pull rope 313 extends downward to the bottom of the connecting part 31 and connects to the hanging part 32. A hydraulic rod 314 is also located inside the cavity 311. The push rod end of the hydraulic rod 314 is hemispherical, and the push rod of the hydraulic rod 314 is used to push the pull rope 313 to bend in the horizontal direction.

[0027] Under the rotation of the electric rotating shaft 312, the pull rope 313 can continuously wind onto or away from the electric rotating shaft 312, adjusting the height of the workpiece. On the one hand, it can prevent the workpiece from colliding with other debris during movement, thus protecting the workpiece. On the other hand, it can change the relative position with the water spray head 410 during rinsing, ensuring no rinsing dead corners exist. Furthermore, after rinsing, the push rod of the hydraulic rod 314 extends, causing the vertically taut pull rope 313 to bend. Then, the push rod of the hydraulic rod 314 quickly retracts, and the pull rope 313 returns to its original position under the pulling action of the mounting part 32. This causes the mounting part 32 and the workpiece to shake, removing some of the water stains adhering to the surface of the workpiece.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
