Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, and in particular relates to an adjustable spraying device for spray guns. Background Technology

[0002] In the field of metal processing, spraying technology is often used for metal surface anti-corrosion, decorative and functional coating preparation, and is widely used in production scenarios such as aerospace parts manufacturing, ship steel structure treatment, and mechanical equipment surface treatment.

[0003] In existing spraying equipment, the spray gun nozzle is the core component for paint output. During operation, due to the viscosity of metallic paint, the paint residue on the outside of the spray gun nozzle can easily harden rapidly under high temperature and oxidation, forming a hard shell. These hard shells adhere to the outside of the nozzle, which not only block the paint channel, but also seriously affect the atomization effect of the nozzle, resulting in quality defects such as uneven coating thickness, surface sagging, and orange peel during spraying, which greatly reduces the yield and production efficiency of metal processing products. Summary of the Invention

[0004] The purpose of this utility model is to provide an adjustable spray gun spraying device to solve the problem mentioned in the background art that, during the operation of existing spraying equipment, the paint residue on the outside of the spray gun nozzle is easily hardened rapidly under high temperature and oxidation, forming a hard shell.

[0005] This invention is achieved by providing an adjustable spray gun spraying device, including a frame.

[0006] A cleaning box is fixed to one end of the top of the frame, and a workbench is set above the cleaning box. An L-shaped fixed frame is fixed to the other end of the top of the frame, and a movable sleeve is fitted on the outside of the L-shaped fixed frame. A rectangular frame is slidably connected to the outside of the movable sleeve, and a spray gun is fixed to the outside of the rectangular frame. A cylinder is fixed to the side of the movable sleeve, and the output end of the cylinder is connected to the inner wall of the rectangular frame.

[0007] The L-shaped fixing frame is equipped with a lifting mechanism, which is used to drive the movable sleeve to move vertically;

[0008] The cleaning tank has a cleaning chamber and a water storage chamber at its two ends. A cleaning cylinder is installed through the side of the cleaning chamber via a bearing. A cleaning brush is fixed to the inner wall of the cleaning cylinder. A rotating mechanism is also provided in the cleaning chamber to drive the cleaning cylinder to rotate.

[0009] Preferably, the outer ends of the movable sleeve are provided with sliding grooves, and the inner ends of the rectangular frame are fixed with sliders, which are located in the sliding grooves.

[0010] In the above technical solution, the sliding block of the slide groove allows the rectangular frame to move laterally on the outside of the movable sleeve.

[0011] Preferably, the lifting mechanism includes a motor, which is fixed to the top of the L-shaped fixed frame, and the output end of the motor is connected to a lead screw. The lead screw is vertically installed on the side of the L-shaped fixed frame and is threaded through the movable sleeve.

[0012] In the above technical solution, the motor drives the lead screw to rotate, which in turn causes the lead screw to move vertically on the L-shaped fixed frame, thereby driving the rectangular frame and the spray gun to move vertically to perform spraying operations on the workpiece.

[0013] Preferably, a second motor is installed at the midpoint of the cleaning chamber, and the output end of the second motor is connected to the worktable.

[0014] In the above technical solution, the spraying position on the workpiece can be adjusted by rotating the worktable driven by the second motor.

[0015] Preferably, the rotating mechanism includes a motor three, which is fixed to the top of the inner wall of the cleaning chamber, and a gear one is provided at the output end of the motor three. A gear two is sleeved on the outer side of the cleaning cylinder, and the gear two meshes with the gear one.

[0016] In the above technical solution, the motor drives gear one to rotate, which in turn drives gear two and the cleaning cylinder to rotate and brush the spray gun.

[0017] Preferably, a cleaning pipe is fixed to the inner wall of the cleaning chamber, and the cleaning pipe is horizontally arranged with the cleaning cylinder. A delivery pump is provided in the water storage chamber, and the delivery pump is connected to the cleaning pipe through the delivery pipe.

[0018] In the above technical solution, when cleaning the spray gun, the water in the water storage chamber can be transported to the cleaning pipe and sprayed into the cleaning cylinder by the delivery pump.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The lifting mechanism lowers the movable sleeve, rectangular frame, and spray gun to align with the cleaning cylinder. Then, by depressurizing the cylinder, the rectangular frame and spray gun are moved closer to the cleaning cylinder, allowing the spray gun to be inserted into the cleaning cylinder. The rotating mechanism then rotates the cleaning cylinder, causing the cleaning brush inside the cylinder to scrub the outside of the spray gun. This technical solution, with its adjustable spray gun, allows for convenient cleaning of the spray gun before each spraying operation. The continuous and stable scrubbing force effectively breaks down the hardened paint shell. Compared to manual scraping, this method not only significantly improves cleaning efficiency but also reaches deep into the corners and crevices outside the spray head to thoroughly remove stubborn hardened paint shells, ensuring a clean spray gun.

[0021] 2. The motor drives the lead screw to rotate, which in turn moves the threaded sleeve and rectangular frame vertically. By depressurizing the cylinder, the rectangular frame moves laterally on the sleeve, allowing the spray gun to be inserted into the cleaning cylinder. The adjustable spray gun allows for quick adjustment of the relative position between the spray gun and the workpiece, ensuring precise matching to current operational needs, guaranteeing uniform spraying and coating quality, and enhancing the equipment's applicability in complex and ever-changing metal processing environments.
