Description

Technical Field

[0001] This utility model relates to the field of powder spraying bin technology, and in particular to an electrostatic metal powder spraying bin. Background Technology

[0002] Electrostatic spraying refers to a coating method that uses the principle of corona discharge to make atomized paint negatively charged under the action of a high-voltage DC electric field and then adsorbed onto the surface of a positively charged substrate for discharge. Electrostatic spraying equipment consists of a spray gun, a spray cup, and a high-voltage power supply for electrostatic spraying. During electrostatic spraying, a powder spraying chamber is needed to place the metal workpiece and prevent the paint from drifting out during spraying.

[0003] A static spraying chamber disclosed in Chinese utility model patent application CN221907928U, while using a conveyor belt assembly to allow a circular tray to be secured in a hanging slot, and utilizing bearings, a rotating rod, and a moving rod to facilitate the rotation of the base and rotating rod, and utilizing hanging openings on the circular tray and arc-shaped extension plate to easily suspend ornaments, allowing the ornaments to rotate and move, can assist personnel in completing large-scale ornament spraying, saving personnel time and effort, and improving spraying efficiency to a certain extent. However, the existing equipment only... The workpiece can rotate and move, but the height of the powder spraying station cannot be quickly adjusted according to the worker's physical condition. During electrostatic spraying, the paint is adsorbed into the electrostatic powder spraying chamber and cannot be dropped for recycling. It is also impossible to collect residual paint in the electrostatic powder spraying chamber. Workers cannot see the spraying effect on the corners and shaded sides of the workpiece. Quickly opening and closing the chamber door cannot effectively prevent external dust and foreign objects from entering the spraying area. It is also impossible to quickly check whether the sprayed workpiece is qualified after spraying. It is also impossible to ensure that the paint can evenly cover all surfaces of the workpiece to reduce problems such as missed spraying and uneven coating. Therefore, this application provides an electrostatic metal powder spraying chamber to meet the requirements. Utility Model Content

[0037] like Figures 1 to 6As shown, an embodiment of this utility model provides an electrostatic metal powder spraying chamber, including a powder spraying base 1. An electrostatic powder spraying chamber 2 is inserted into the upper surface of the powder spraying base 1. A reagent box 3 is provided on one side of the upper surface of the powder spraying base 1. A reagent pump 4 is inserted into one side of the reagent box 3. A reagent seat 301 is provided on one side of the reagent box 3. A reagent nozzle 5 is provided inside the reagent seat 301. A reagent tube is inserted into one end of the reagent nozzle 5. The reagent pump 4 is inserted into one end of the reagent tube. The reagent nozzle 5 is sleeved on one end of the reagent pump 4. A buckle 6 is provided on one side of the powder spraying base 1. A recycling box 7 is provided on one side of the buckle 6. The bottom of the powder spraying base 1 has an inner... A powder spraying chute 101 is provided on the side, and recycling sliders are provided on both sides of the recycling bin 7. The recycling sliders are slidably connected inside the powder spraying chute 101. A support assembly 8 is provided on the lower surface of the powder spraying base 1. The support assembly 8 includes a support rod 801, a support groove 802, a support hydraulic press 803, and a support foot 804. The support rod 801 has a support groove 802 inside, and the support hydraulic press 803 is inserted into the support groove 802. A support foot 804 is provided at one end of the support hydraulic press 803. A fan 9 is provided on the upper surface of the electrostatic powder spraying chamber 2, and a handheld lighting lamp 10 is provided on one side of the electrostatic powder spraying chamber 2.

[0038] The hydraulic press 803 drives the support foot 804 to extend and retract, allowing the support foot 804 to extend and retract under the support rod 801 and support the ground. This allows for quick adjustment of the height of the powder spraying station 1, optimizing the working posture and improving work efficiency according to the employee's physical condition and work needs. By adding electrostatic shielding coating to the reagent box 3 and rotating the reagent pump 4 to extract the coating from the reagent box 3, the reagent nozzle 5 in the reagent seat 301 is removed to spray the electrostatic powder spraying chamber 2. This reduces the amount of coating adsorbed into the electrostatic powder spraying chamber 2 during electrostatic spraying. During electrostatic spraying, the coating can fall into the recycling box 7 for recycling. After spraying, the fan 9 on the electrostatic powder spraying chamber 2 blows air into the interior of the electrostatic powder spraying chamber 2, allowing any residual coating in the electrostatic powder spraying chamber 2 to fall into the recycling box 7 for recycling. During the spraying process, the worker removes the handheld light 10 to illuminate the sprayed workpiece, ensuring complete spraying when the worker cannot see the corners and shaded sides of the workpiece.

[0039] like Figures 4 to 9As shown, the electrostatic powder spraying chamber 2 has a chamber door assembly 11 on one side. The chamber door assembly 11 includes a chamber door rod 111, a left motor 112, a left lead screw 113, a right motor 114, a right lead screw 115, a left chamber door 116, a right chamber door 117, and a top rod 118. The left motor 112 is inserted into one side of the chamber door rod 111, and the left lead screw 113 is inserted into one end of the left motor 112. The right motor 114 is inserted into the other side of the chamber door rod 111, and the right lead screw 115 is inserted into one end of the right motor 114. The upper surface of the chamber door rod 111... A left compartment door 116 and a right compartment door 117 are slidably connected from front to back. A top rod 118 is slidably connected to the upper surface of the left compartment door 116. A left slider is provided on the upper and lower surfaces of the left compartment door 116, and a right slider is provided on the upper and lower surfaces of the right compartment door 117. A left sliding groove and a right sliding groove are provided on the upper surface of the compartment door rod 111 from front to back. A left upper sliding groove and a right upper sliding groove are provided on the lower surface of the top rod 118 from front to back. A left slider is slidably connected inside the left lower sliding groove and the left upper sliding groove, and a right slider is slidably connected inside the right lower sliding groove and the right upper sliding groove. A left slider is connected to the left door 116 near the door rod 111, with a left lead screw 113 threaded through its internal thread. A right lead screw 115 is threaded through the right slider of the right door 117 near the door rod 111. A fixed slide rail 12 is provided on the upper surface of the electrostatic powder spraying chamber 2. A fixed motor 13 is inserted into one side of the fixed slide rail 12, and a fixed lead screw 14 is inserted into one end of the fixed motor 13. A fixed slider is provided on one side of the fixed assembly 15, and a fixed slider is slidably connected inside the fixed slide rail 12. The fixed slider has an internal thread... A fixed lead screw 14 is threaded through the fixed slide rail 12. A fixed component 15 is slidably connected to the lower surface of the fixed slide rail 12. The fixed component 15 includes a fixed base 151, a rotary motor 152, a fixed bolt 153, and a fixed hook 154. The rotary motor 152 is inserted into the lower surface of the fixed base 151. The fixed bolt 153 is threaded through one end of the rotary motor 152. The fixed hook 154 is provided on the lower surface of the fixed bolt 153. A fixed threaded hole is opened on the lower surface of the rotary motor 152. The fixed bolt 153 is threaded through the internal thread of the fixed threaded hole.

[0040] The left motor 112 drives the left lead screw 113 to rotate, causing the left compartment door 116 to slide open and close within the compartment door rod 111 and the top rod 118. The right motor 114 drives the right lead screw 115 to rotate, causing the right compartment door 117 to slide open and close within the compartment door rod 111 and the top rod 118. This allows for rapid opening and closing of the left and right compartment doors 116 and 117, effectively preventing external dust and foreign objects from entering the spraying area, maintaining a clean and stable spraying environment, and ensuring the quality and safety of the spraying operation. The fixed motor 13 drives the fixed lead screw 14 to rotate, causing the fixed assembly... The component 15 moves back and forth under the fixed slide rail 12, which can quickly move the fixed hook 154 under the fixed component 15 out of the electrostatic powder spraying chamber 2. This allows workers to quickly check whether the workpiece is qualified after spraying, promptly identify and repair unqualified sprayed parts, reduce rework and repainting time, and improve overall production efficiency. The fixed hook 154 is driven to rotate by the rotary motor 152, so that the workpiece fixed on the fixed hook 154 rotates in the electrostatic powder spraying chamber 2. This allows the paint to evenly cover all surfaces of the workpiece during spraying, reducing the problems of missed spraying and uneven coating.

[0041] The working principle of the technical solution provided by this utility model is as follows: Before spraying, the worker starts the support hydraulic press 803 to drive the support foot 804 to extend and retract, so that the support foot 804 extends and retracts under the support rod 801 and supports the ground to quickly adjust the height of the powder spraying seat 1, which facilitates the worker's spraying. By adding electrostatic shielding coating into the reagent box 3, the worker drives the left screw 113 to rotate through the left motor 112, so that the left compartment door 116 slides open and closes within the compartment door rod 111 and the top rod 118. The right motor 114 drives the right screw 115. The rotation causes the right compartment door 117 to slide open and close within the compartment door rod 111 and top rod 118. The left compartment door 116 and right compartment door 117 are then quickly opened. Before spraying, the reagent pump 4 extracts paint from the reagent tank 3. The worker removes the reagent nozzle 5 from the reagent holder 301 to spray the electrostatic powder coating chamber 2, reducing paint adsorption into the electrostatic powder coating chamber 2 during electrostatic spraying. The fixed motor 13 drives the fixed screw 14 to rotate, causing the fixed component 15 to move forward under the fixed slide rail 12, thus moving the fixed hook 154 under the fixed component 15. The workpiece to be coated is placed on the fixed hook 154 after exiting the electrostatic powder coating chamber 2. The fixed motor 13 drives the fixed screw 14 to rotate, moving the workpiece on the fixed hook 154 into the electrostatic powder coating chamber 2 for coating. During the coating process, the rotary motor 152 drives the fixed hook 154 to rotate, causing the workpiece fixed on the fixed hook 154 to rotate within the electrostatic powder coating chamber 2, ensuring that the coating evenly covers all surfaces of the workpiece. After coating, the fixed motor 13 drives the fixed screw 14 to rotate, moving the fixed assembly 15... Part 15 moves under the fixed slide rail 12, causing the fixed hook 154 under the fixed component 15 to move out of the electrostatic powder spraying chamber 2. The handheld light 10 is removed to illuminate the workpiece being sprayed. Illumination is provided when the corners and shaded sides of the workpiece cannot be seen by the worker, ensuring the completeness of the workpiece spraying. This allows the worker to quickly check whether the workpiece is sprayed properly, and to promptly identify and repair any unqualified sprayed parts. After spraying, the fan 9 on the electrostatic powder spraying chamber 2 blows air into the interior of the electrostatic powder spraying chamber 2, causing the residual paint in the electrostatic powder spraying chamber 2 to fall into the recycling box 7 for recycling.
