A track is fixedly installed on the lower surface of the spraying chamber. Multiple drive mechanisms are slidably connected to the outer side of the track. A support frame is fixedly connected to the upper surface of the multiple drive mechanisms. A rotating frame is rotatably connected to the outer side of the support frame. A rotating seat is fixedly installed inside the rotating frame. A fixing frame is fixedly installed on the inner surface of the support frame. A motor is fixedly installed inside the fixing frame. This device can gather and collect excess paint, preventing it from drifting outwards and adhering to the bottom and side walls of the support plate, thus reducing the difficulty of later cleaning. At the same time, it can collect and recycle drifted paint, reducing paint waste. Furthermore, when spraying complex parts such as automobile chassis or front and rear axles, it facilitates the paint to cover the inner skeleton, improving the spraying coverage effect.

[0004] In traditional electrophoretic spraying equipment, workpieces need to be manually transferred between different workstations, resulting in low work efficiency. Excess paint drips directly from the electrophoretic spraying equipment and cannot be collected, causing paint waste and increasing production costs. Utility Model Content

[0005] The purpose of this invention is to provide an electrophoretic spraying device that is easy to recycle, in order to solve the problem of low work efficiency caused by the need for manual transfer of workpieces between different workstations in traditional electrophoretic spraying devices mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrophoretic spraying device that is easy to recycle, comprising a processing box, wherein the processing box has an elliptical rectangular structure, and a recycling chamber and a processing chamber are respectively provided on both sides inside the processing box; The processing box has installation compartments at both ends of its top. Gear disks are rotatably connected inside the installation compartments. The gear disks are driven by a motor. Chains are sleeved on the outside of the two gear disks.

[0007] Preferably, the processing box is provided with guide sleeves on both sides of the top, and the two guide sleeves are located at the tangent of the two installation chambers. The bottom of the installation chamber and the guide sleeves form an elliptical rectangular slot on the top of the inner side of the processing box. The processing box is provided with loading and unloading windows at one end.

[0008] Preferably, the hook extends through the elliptical rectangular slot at the top of the inner side of the processing box to the inside of the recovery chamber and the processing chamber. The hook moves along the elliptical rectangular slot inside the processing box with the chain. Two symmetrically distributed elastic electrode strips are fixedly connected to the top of the processing chamber. The electrode strips are located on both sides of the slot, and the electrode strips contact the hook to form an electrical connection.

[0009] Preferably, the top of the recovery chamber is provided with a blower hole, the top of the blower hole is fixedly connected to a guide shroud, and the top of the guide shroud is fixedly connected to a fan.

[0010] Preferably, both the bottom of the recycling chamber and the bottom of the processing chamber are provided with mounting grooves, and a recycling drawer is slidably connected inside the mounting grooves, with a filter screen at the bottom of the recycling drawer.

[0011] Preferably, the processing cavity is fixedly connected with equidistant and symmetrically distributed spray pipes, and the opposite sides of the spray pipes are fixedly connected with equidistantly distributed nozzles, and the nozzles installed between two symmetrically distributed spray pipes are aligned with each other.

[0012] Preferably, the upper end of the spray tube passes through the top of the processing cavity and extends to the outside of the processing cavity. A feed tube is installed on the top of the processing cavity, and the feed tube has an input end and an output end connected to each spray tube.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figures 1 to 4 The present invention provides the following technical solution: An easily recyclable electrophoretic spraying device includes a processing box 1, which has an elliptical rectangular structure. The processing box 1 has a recycling chamber 2 and a processing chamber 3 on its two sides. The processing box 1 has an installation chamber 4 at both ends of its top. The installation chamber 4 is rotatably connected to a gear disk 6, which is driven by a motor. The two gear disks 6 are fitted with chains 7 on their outer sides, and the bottom of the chains 7 is fixedly connected with hooks 8 that are evenly distributed.

[0019] The processing box 1 has guide sleeves 5 on both sides of the top. Both guide sleeves 5 are located at the tangent of the two installation chambers 4. The bottom of the installation chambers 4 and the guide sleeves 5 form an elliptical rectangular slot on the top inner side of the processing box 1. The processing box 1 has an loading and unloading window 17 at one end. The hook 8 extends through the elliptical rectangular slot on the top inner side of the processing box 1 to the inside of the recovery chamber 2 and the processing chamber 3. The hook 8 moves along the elliptical rectangular slot inside the processing box 1 with the chain 7. The top of the processing chamber 3 is fixedly connected to two symmetrically distributed elastic electrode strips. The electrode strips are located on both sides of the slot, and the electrode strips contact the hook 8 to form an electrical connection.

[0020] The workpiece to be electrophoretically coated is suspended on the hook 8 fixedly connected to the bottom of the chain 7 through the loading and unloading window 17 set at one end of the processing box 1. The motor of the gear disk 6 inside the installation chamber 4 is started, and the motor drives the gear disk 6 to rotate. Since the chain 7 is sleeved on the outside of the gear disk 6 in the two installation chambers 4, the rotating gear disk 6 will drive the chain 7 to move synchronously.

[0021] The guide sleeves 5 on both sides of the top of the processing box 1 play a role. Since the guide sleeves 5 are located at the tangent of the two mounting chambers 4, they can guide the moving chain 7, so that the chain 7 moves stably along the elliptical rectangular slot formed on the top of the inner side of the processing box 1. The hook 8 will move along the elliptical rectangular slot with the chain 7 inside the processing box 1, and then move the workpiece to be processed.

[0022] When the hook 8 drives the workpiece to be processed into the processing chamber 3, the two symmetrically distributed elastic electrode strips fixedly connected to the top of the processing chamber 3 will contact the hook 8, thereby forming an electrical connection. The workpiece to be processed obtains the current required for electrophoretic spraying through the hook 8. After the workpiece completes electrophoretic spraying in the processing chamber 3, the chain 7 will continue to drive the hook 8 and the workpiece to move, and transport the workpiece to the recovery chamber 2 on the other side of the processing box 1.

[0023] Example 2: Based on Example 1, please refer to... Figures 3 to 6 The following structure was also disclosed: The top of the recycling chamber 2 is provided with a blower hole 9, and the top of the blower hole 9 is fixedly connected with a guide shroud 10, and the top of the guide shroud 10 is fixedly connected with a fan 11; the bottom of the recycling chamber 2 and the bottom of the processing chamber 3 are both provided with mounting grooves 12, and a recycling drawer 13 is slidably connected inside the mounting groove 12, and a filter screen is provided at the bottom of the recycling drawer 13.

[0024] Inside the processing chamber 3, there are equidistant and symmetrically distributed spray pipes 14. On opposite sides of the spray pipes 14, there are equidistantly distributed nozzles 15. The nozzles 15 installed between two symmetrically distributed spray pipes 14 are aligned with each other. The upper end of the spray pipe 14 passes through the top of the processing chamber 3 and extends to the outside of the processing chamber 3. A feed pipe 16 is installed on the top of the processing chamber 3. The feed pipe 16 has an input end and an output end connected to each spray pipe 14.

[0025] When the hook 8 pulls the workpiece into the processing chamber 3, the feed pipe 16 installed at the top of the processing chamber 3 starts to work. The feed pipe 16 introduces electrophoretic coating through its input end and distributes the coating through its output ends to each spray pipe 14 fixedly connected inside the processing chamber 3.

[0026] The electrophoretic coating entering the spray pipe 14 will be sprayed out from the equally spaced nozzles 15 fixedly connected on opposite sides of the spray pipe 14. Since the nozzles 15 between the two symmetrically distributed spray pipes 14 are aligned with each other, the sprayed electrophoretic coating can more comprehensively cover the surface of the workpiece to be processed as it moves slowly with the hook 8, thus realizing the electrophoretic coating of the workpiece.

[0027] During the spraying process, some excess electrophoretic coating that does not adhere to the surface of the workpiece will drip down due to gravity. These dripping coatings will fall into the recycling drawer 13, which is slidably connected inside the mounting groove 12 at the bottom of the processing chamber 3. The filter screen at the bottom of the recycling drawer 13 will filter the dripping coatings, remove impurities from the coatings, and facilitate subsequent recycling of the coatings.

[0028] After the workpiece is sprayed in the processing chamber 3, the chain 7 continues to drive the hook 8 and the workpiece into the recovery chamber 2. At this time, the fan 11 on the top of the air guide shroud 10 of the recovery chamber 2 starts. The airflow generated by the fan 11 is guided by the air guide shroud 10 and blown onto the surface of the workpiece through the air blowing hole 9 on the top of the recovery chamber 2. This can help the paint on the surface of the workpiece dry faster and also blow off excess paint from the surface of the workpiece.

[0029] Paint that is blown off or drips naturally will also fall into the recycling drawer 13 in the mounting groove 12 at the bottom of the recycling chamber 2. After being filtered by the filter screen, it will be collected. When the amount of paint collected in the recycling drawer 13 reaches a certain amount, the recycling drawer 13 can be slid outward along the mounting groove 12 and removed. The collected filtered paint can then be further processed or reused. In addition, the wind speed of the fan 11 and the amount of material supplied from the feed pipe 16 to the spray pipe 14 can be adjusted according to the workpiece spraying requirements to optimize the spraying effect and recycling efficiency.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
