Technical Field
[0001] This utility model relates to the field of luminous silicone spraying technology, specifically to a luminous silicone spraying device capable of uniform spraying. Background Technology
[0002] Luminous silicone spraying is a surface treatment technology that sprays silicone material containing luminous powder (also known as fluorescent powder or photoluminescent powder) onto the surface of an object, making it glow in the dark. In the existing technology, the object is clamped and fixed on the luminous silicone spraying device, but the device has difficulty spraying the clamped position, resulting in spraying dead corners and making the overall spraying less than ideal.
[0003] For example, patent publication number CN222658977U describes a spraying device capable of uniform spraying, including an operating frame. A support plate is fixedly connected inside the operating frame, and a rotating disk is rotatably connected to the top of the support plate. A bidirectional lead screw is rotatably connected inside the rotating disk, and an auxiliary rotating block is rotatably connected to one side of the rotating disk. The beneficial effect of this invention is that by adding a hydraulic cylinder, the output end of the hydraulic cylinder actuates a fixed plate via a rotating shaft, which in turn actuates the spray gun via a reaction force. The spray gun is rotated and adjusted via a rotating shaft and a support base plate, thus adjusting its vertical orientation. The auxiliary rotating block rotates, driving the bidirectional lead screw to rotate, which in turn adjusts the position of the adjusting block and the spraying part clamping block. The two spraying part clamping blocks clamp and fix the workpiece to be sprayed, stabilizing the spraying process. However, this invention suffers from the problem that by clamping and fixing the item onto the luminous silicone spraying device, the device struggles to spray the clamped area, resulting in spraying dead zones and an unsatisfactory overall spraying coverage.
