[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a spraying device for surface treatment of sheet metal parts includes a base 1, the top of the base 1 is fixedly connected to a conveyor belt 2, the top of the base 1 is fixedly connected to a hood 3, the top of the hood 3 is fixedly connected to a liquid outlet bin 4, the bottom end of the liquid outlet bin 4 is fixedly connected to a nozzle 5, the top of the hood 3 is fixedly connected to a blower 8, a cleaning device 6 is provided inside the hood 3, the outer wall of the hood 3 is provided with a movable groove 61, the inner wall of the movable groove 61 is slidably connected to a movable block 63, the top of the movable block 63 is fixedly connected to a first spring 62, the end of the first spring 62 away from the movable block 63 is fixedly connected to the top of the movable groove 61, the outer wall of the movable block 63 is fixedly connected to a protruding rod 64, the outer wall of the protruding rod 64 is fixedly connected to a connecting arm 65, and the end of the connecting arm 65 away from the protruding rod 64 is fixedly connected to a force-bearing rod 67.

[0023] The outer wall of the movable block 63 is rotatably connected to the cleaning roller 66 , and the outer wall of the force-bearing rod 67 is an inclined surface.

[0024] The cleaning roller 66 can be rotated to clean the surface of the sheet metal part that needs to be sprayed.

[0025] The bottom end of the force-bearing rod 67 passes through and is rotatably connected to an extrusion wheel 68 , and the bottom end of the extrusion wheel 68 and the bottom end of the cleaning roller 66 are located at the same horizontal height.

[0026] The force-bearing rod 67 is squeezed to drive the cleaning roller 66 to move upward synchronously.

[0027] The outer wall of the base 1 is provided with a collecting device 7 , and the outer wall of the base 1 is fixedly connected with a collecting box 71 .

[0028] The collecting device 7 can collect the sprayed sheet metal parts, making it easier for the staff to pick them up later.

[0029] The inner wall of the collection box 71 is rotatably connected to a rotating shaft 72 , and the outer wall of the rotating shaft 72 is fixedly connected to a baffle 73 .

[0030] The rotation of the rotating shaft 72 can drive the baffle 73 to deflect.

[0031] The bottom end of the baffle 73 is fixedly connected to a second spring 75 , and one end of the second spring 75 away from the baffle 73 is fixedly connected to the bottom end of the collection box 71 .

[0032] Through the second spring 75 , the second spring 75 can support the baffle 73 without being affected by external forces.

[0033] A cushion block 74 is fixedly connected to the top of the baffle 73 , and the baffle 73 is inclined.

[0034] The pad 74 can cushion the falling sheet metal parts, thereby preventing the sheet metal parts from being worn.

[0035] The utility model provides a spraying device for surface treatment of sheet metal parts. The specific working principle is as follows: the sheet metal parts to be sprayed are placed above the conveyor belt 2, and the conveyor belt 2 drives the sheet metal parts to move to the inside of the hood 3. The sheet metal parts squeeze the extrusion wheel 68 until the bottom end of the extrusion wheel 68 fits with the top end of the sheet metal parts, and the extrusion wheel 68 drives the force-bearing rod 67 to move upward. The force-bearing rod 67 drives the protruding rod 64 to move upward through the connecting arm 65. The upward movement of the protruding rod 64 drives the movable block 63 to move on the inner wall of the movable groove 61. The movable block 63 squeezes the first spring 62 and drives the cleaning roller 66 to move upward. In the process of continuous movement of the sheet metal parts, the cleaning roller 66 cleans the outer surface of the sheet metal parts, so that sheet metal parts of different sizes can be cleaned. The metal parts are continuously transported on the conveyor belt 2, and the liquid outlet bin 4 evenly sprays the surface of the sheet metal parts through the nozzle 5. When the sprayed sheet metal parts pass under the blower 8 on the conveyor belt 2, the blower 8 blows on the outer surface of the sheet metal parts so that the sprayed paint can be quickly dried. When the sheet metal parts leave the conveyor belt 2 and fall into the interior of the collection box 71, the sheet metal parts first contact the pad 74 during the falling process, and the sheet metal parts squeeze the pad 74. While the pad 74 is squeezed, the baffle 73 drives the rotating shaft 72 to rotate, and the baffle 73 flips downward to squeeze the second spring 75. The second spring 75 is squeezed and relies on its own elastic force to apply a supporting force in the opposite direction to the baffle 73, thereby driving the baffle 73 to cushion the fall of the sheet metal parts and protect the sheet metal parts.
