Description

Technical Field

[0001] This utility model relates to the field of spotlight production technology, and in particular to an electrostatic spray head for spotlight production. Background Technology

[0002] In the production process of spotlights, electrostatic spray heads are required to spray paint the spotlight components. A typical electrostatic spray head usually includes a gun body and a nozzle mounted on one end of the gun body. A handle is set at the handle of the gun body to control the nozzle switch. The spraying is turned on and off by operating the handle, which meets the basic requirements of spraying operations.

[0003] When using existing electrostatic spray heads, paint residue is easily left at the nozzle after spraying. This residue gradually solidifies and accumulates, and air can easily enter the inside of the nozzle, causing the paint inside to become damp and hardened, which in turn affects the smooth progress of subsequent spraying operations and causes inconvenience. To address this, an electrostatic spray head for spotlight production is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies where paint residue easily remains at the nozzle outlet, gradually solidifies and accumulates, and air easily enters the nozzle, causing the paint inside to become damp and hardened. Therefore, this invention proposes an electrostatic spray head for spotlight production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electrostatic spray head for spotlight production includes a gun body and a nozzle installed at one end of the gun body. A handle for controlling the nozzle switch is hinged to the handle of the gun body. Slide tracks are provided on both sides of the nozzle. An n-shaped sliding frame is slidably connected between the slide tracks. A horizontal plate is fixedly connected to one side of the sliding frame. A mounting plate is fixed to one end of the horizontal plate by bolts. A through clearance opening is provided on one side of the mounting plate. The clearance opening is fan-shaped. A baffle is fixed on one side of the mounting plate. When the nozzle is closed, the baffle is located on one side of its discharge port and the clearance port is located below its discharge port. A drive assembly is disposed on both sides of the gun body for driving the sliding frame to move.

[0006] As a further embodiment of this utility model, the drive assembly includes two fixed shafts, a drive frame, and two drive shafts. The fixed shafts are respectively fixed on both sides of the nozzle. One end of each fixed shaft is rotatably connected to a swing frame. One side of each swing frame is provided with a through drive groove. The drive shafts are respectively fixed on both sides of the sliding frame and slide with the drive grooves. The drive frame is rotatably connected to one side of the handle and is arranged in a U-shape. The two ends of the drive frame are respectively rotatably connected to one end of the two swing frames.

[0007] As a further embodiment of this utility model, a brush plate is fixedly connected to one side of the mounting plate, and the brush plate is located between the clearance opening and the baffle.

[0008] As a further improvement of this utility model, a spring is installed between the handle and the handle of the gun body via a spring seat.

[0009] As a further improvement of this invention, the baffle plate is provided with inclined surfaces at both corners near the nozzle.

[0010] As a further improvement of this invention, the baffle is made of rubber.

[0011] In this application, during use, the nozzle is switched on and off by controlling the handle. When the handle is turned, it pulls the drive frame to rotate, which in turn pulls the swing frame to rotate around the fixed axis. The drive groove on the swing frame and the drive shaft work together to move the sliding frame upward. The sliding frame moves the clearance port to the side of the nozzle's outlet. The clearance port is fan-shaped, matching the nozzle's outlet shape, thus ensuring normal nozzle outlet. After spraying, the handle returns to its original position under the action of the spring, which in turn resets the drive frame, swing frame, and sliding frame. When the mounting plate resets, it first moves the brush plate downward, which cleans the nozzle's outlet. Finally, the baffle seals the nozzle's outlet to prevent air from entering and causing the raw material to become damp and clump, facilitating the next use.

[0012] Beneficial effects: In this utility model, the electrostatic spray head for spotlight production uses a brush plate, a rubber baffle, a spring, and a drive assembly in combination. After spraying, the spring drives the handle and drive assembly to reset. During the downward movement of the sliding frame, the brush plate first wipes the residual paint at the nozzle outlet to prevent the residue from solidifying and accumulating. Then, the baffle tightly fits against the outlet to seal it, effectively preventing air from entering, preventing the internal paint from becoming damp and hardening, reducing the risk of outlet blockage, and ensuring the smooth operation of the nozzle in subsequent use. In this utility model, the electrostatic spray head for spotlight production uses a fan-shaped structure of the clearance opening in conjunction with a drive component and a handle. When spraying paint, pressing the handle drives the drive component to move the sliding frame along the slide, so that the clearance opening is precisely aligned with the nozzle outlet. Its curvature and opening size are perfectly matched with the nozzle outlet shape, so as not to obstruct the paint spraying and ensure that the paint can be smoothly sprayed out in the required mist form. This ensures the continuity of the spraying operation and the consistency of the spraying quality in spotlight production, and reduces the amount of raw material adhering to the nozzle.
