Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to an angle-adjustable spray gun for a powder coating production line. Background Technology

[0002] In modern industrial production, powder coating technology has been widely used in automobile manufacturing, home appliance production, metal processing and other fields due to its advantages such as high efficiency and environmental friendliness. Traditional fixed-angle spray guns have obvious technical limitations: First, when dealing with complex curved workpieces, fixed spray guns are difficult to achieve uniform coating, which can easily lead to uneven coating thickness and missed areas; second, after long-term use, powder tends to accumulate at the nozzle, resulting in a decrease in atomization effect and affecting the coating quality.

[0003] Patent document CN213377312U discloses a spray gun used in an automated metal surface coating production line, including a spray gun housing and a connecting column. A storage chamber is fixedly connected to the bottom inner wall of the spray gun housing. The storage chamber has a cylindrical structure, and a circular through-hole is opened on the top outer wall of the storage chamber, extending through the top inner wall of the storage chamber into the interior of the storage chamber. In this invention, the connecting column is screwed into the output column. By holding the handle and slowly screwing the rotating column in, the air is continuously compressed, resulting in a relatively high internal pressure and a certain impact force. This force causes the sprayed liquid on the inner wall of the suction tube and the output column to flow backward into the storage chamber. This ensures that the sprayed liquid in the suction tube and the output column is cleaned and no longer clogs the spray gun; it also allows the sprayed liquid adhering to the inner wall of the suction tube and the output column to be reused, avoiding resource waste.

[0004] However, the spray guns used in this automated metal surface coating production line are not easy to quickly remove residual powder from the nozzle surface, which can easily cause nozzle clogging and uneven coating. Utility Model Content

[0009] The adjustment assembly includes a lead screw 1 slidably connected to one side of the connecting frame, a movable block threadedly connected to one side of the lead screw 1, a fixed connecting rod on one side of the movable block, and a movable arm slidably connected to one side of the connecting rod.

[0010] The cleaning assembly includes an air supply plate fixedly connected to one side of a connecting plate, a nozzle fixedly connected to one side of the air supply plate, a sweeping shaft fixedly connected to one side of the connecting plate, and a motor fixedly connected to one side of the sweeping shaft.

[0011] As a further embodiment of this utility model, a motor is fixedly connected to one side of the lead screw, a motor is fixedly connected inside the connecting rod, and a rotating arm is fixedly connected to one side of the motor. The rotating arm serves to drive the spray gun body to adjust its angle.

[0012] As a further embodiment of this utility model, an air inlet pipe is fixedly connected to one side of the air supply plate, and an air pump is fixedly connected to one side of the air inlet pipe. The air pump provides compressed air.

[0013] As a further embodiment of this utility model, a fixed frame is connected to one side of the fixed cover of the air pump, and a second lead screw is slidably connected to one side of the fixed frame. The second lead screw drives the connecting plate to move up and down.

[0014] As a further embodiment of this utility model, a motor is fixedly connected to the second lead screw, and a pulley is fixedly connected to one side of the second lead screw. The pulley serves to transmit motion.

[0015] As a further embodiment of this utility model, a belt is slidably connected to one side of the pulley one, and a pulley two is slidably connected to one side of the belt. The pulley two serves to transmit motion.

[0017] (III) Beneficial Effects

[0018] This utility model provides an adjustable-angle spray gun for a powder coating production line, which has the following advantages:

[0019] 1. This powder coating production line uses an angle-adjustable spray gun. Through the cleaning component, during operation, starting motor three drives screw two to rotate. Screw two rotation moves the cleaning shaft and nozzle to the designated position. Starting motor two then drives the cleaning shaft to clean the nozzles. Starting the air pump delivers compressed air through the air inlet pipe to the air distribution plate, which evenly distributes the air to each nozzle. The air is then sprayed out from the nozzle, cleaning it and removing residual powder from the nozzle surface. This prevents clogging and uneven coating, extends the spray gun's lifespan, and improves coating consistency.

[0020] 2. This powder coating production line uses an angle-adjustable spray gun. Through the setting of the adjustment component, when in use, starting motor one causes motor one to drive the rotating arm to rotate, which in turn drives the spray gun body to rotate. Starting motor four causes motor four to drive lead screw one to rotate, which in turn drives the moving block to move up and down, which in turn drives the spray gun body to move up and down, thereby achieving the adjustment function, avoiding dead angles or uneven coating, improving work efficiency, and reducing human operation errors.
