Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a spraying device with adjustable range. Background Technology

[0002] Spray coating technology, as an important surface treatment process, is widely used in industrial manufacturing, architectural decoration, and other fields. Conventional spray coating equipment mostly adopts a fixed nozzle structure, which has problems such as limited spraying range and poor adaptability when dealing with irregularly shaped workpieces such as cylindrical or square columns.

[0003] Patent CN214864656U discloses a spraying device with an adjustable spraying range, employing a symmetrically arranged arc-shaped spraying frame structure. The opening and closing of the spraying frame is adjusted via a motor-driven bidirectional screw. However, due to the arc shape of the spraying frame, the angles of the spraying components on its inner wall cannot be adjusted. To address this issue, patent CN220195253U discloses a spraying device with an adjustable spraying range, including a fixed plate. Inside the fixed plate, a first adjusting rod and a second adjusting rod are movably mounted via a first adjusting mechanism. Both the first and second adjusting rods have second through slots. By rotating a rotating tube, which, through a second bidirectional screw and a second screw hole, can adjust the sliding plate and the adjusting plate. The sliding plates move closer together within the second through slots via a sliding groove. The adjusting plate, through the action of a turntable and a shaft, compresses or expands an elastic plate, allowing the elastic plate to bend or straighten, facilitating the spraying of paint onto cylindrical and rectangular objects, and offering convenient use.

[0004] Although the above solution can achieve spraying of cylindrical and square workpieces, the angle adjustment between the nozzles mainly relies on the bending of the elastic plate, which has a limited adjustment range and insufficient adjustment accuracy. Utility Model Content

One end of the telescopic rod 105 is inserted into the first support sleeve 101. The side wall of the first support sleeve 101 is provided with a positioning bolt 111 for fixing the telescopic rod 105. The ends of the first support sleeve 101 and the telescopic rod 105 are both vertically connected to a second support sleeve 108. The end of the support sleeve is inserted with a support rod 110. The side wall of the second support sleeve 108 is provided with a locking bolt 109 for fixing the support rod 110. The end of the support rod 110 is fixed with a connecting block 2. Both ends of the connecting block 2 are connected to multiple detachable spraying units 3.

[0015] The spacing between the two support rods 110 is adjustable, which can adjust the spacing between the two spraying units 3. In addition, the length of the support rods 110 is adjustable, which can adjust the overall size of the bracket 1 according to the size of the spraying unit 3 and the spraying object, greatly increasing versatility.

[0016] A rack 106 is embedded in the side wall of the telescopic rod 105. The side wall of the rack 106 is flush with the side wall of the telescopic rod 105. A gear 107 that meshes with the rack 106 is fixed to the end of the first support sleeve 101. A knob 104 is connected to one end of the gear 107. The knob 104 can drive the gear 107 to rotate, and the gear 107 can drive the rack 106 to move, thereby driving the telescopic rod 105 to move and achieve adjustment. The length of the telescopic rod 105 can be adjusted by using the knob 104, which can increase the adjustment accuracy. A limiting hole 102 is provided on the side wall of the first support sleeve 101, and a limiting block 103 that cooperates with the limiting hole 102 is provided on the side wall of the telescopic rod 105, which can prevent the telescopic rod 105 from slipping out of the first support sleeve 101 and ensure the reliability of use.

[0017] In addition, the support rod 110 can be pulled out from the second support sleeve 108 for easy replacement. The support rod can be pulled out from the second support sleeve, and the spraying unit can be disassembled without disassembling the entire device, which significantly reduces maintenance time and costs.

[0018] The spraying unit 3 includes a support plate 303, on which a spray head 304 is provided. The rear end of the spray head 304 is an interface.
