[0016] like Figure 1-4 The device shown is a surface drawing device for producing refrigerator handles. It includes a workbench 1 and a drawing assembly installed above the workbench 1. A rotating plate 2 is rotatably installed above the workbench 1. The rotating plate 2 is square in shape. The drawing assembly includes a mounting platform 3, an air duct 6, and a polishing wheel 8. Four mounting platforms 3 are evenly distributed above the rotating plate 2. A pressure plate 4 is movably installed above the mounting platform 3. An air duct 6 is movably installed on one side of the rotating plate 2. A polishing wheel 8 is movably installed above the other side of the rotating plate 2. The installation position of the polishing wheel 8 is adjacent to the air duct 6. Four baffles 5 are fixedly installed on the surface of the rotating plate 2. The installation positions of the baffles 5 correspond to the mounting platforms 3.
[0017] Waste outlets 15 are provided between the four baffles 5 and the corresponding mounting platforms 3. The waste outlets 15 are located on the surface of the rotating plate 2. A cylinder 3 14 is fixedly installed on the outer wall of the mounting platform 3 facing the baffles 5. The output end of the cylinder 3 14 is fixedly connected to the edge of the pressure plate 4. A drive motor is fixedly installed on the table surface of the workbench 1. The output shaft of the motor is fixedly connected to the center of the rotating plate 2. A cylinder 2 10 is fixedly installed on the table surface of the workbench 1. An air duct 6 is fixedly installed on the output end of the cylinder 2 10. The air outlet of the air duct 6 faces one of the mounting platforms 3.
[0018] A motor 11 is fixedly installed on one side of the workbench 1. A screw 12 is fixedly installed at the output end of the motor 11. The end of the screw 12 is mounted on the workbench 1 via a bearing. A grinding wheel 8 is positioned above the screw 12 and is driven by the screw 12. A slider 16 is sleeved around the screw 12. A connecting rod 7 is fixedly installed on the outer wall of the slider 16. A cylinder 9 is installed above the grinding wheel 8. The grinding wheel 8 consists of a housing and a wheel body. The wheel body is rotatably mounted inside the housing. The output end of the cylinder 9 is fixedly connected to the housing of the grinding wheel 8, and the top end of the connecting rod 7 is fixedly connected to the outer wall of the cylinder 9. A fixing rod 17 is fixedly installed on the outer wall of the slider 16. A groove 13 is provided below the screw 12. The groove 13 is formed on the workbench 1, and the fixing rod 17 is embedded inside the groove 13.
[0019] Example: In the initial state, the pressure plate 4 is attached to the top outer wall of the mounting platform 3. The cylinder 14 is activated, which drives the pressure plate 4 to rise and place the metal plate handle above the mounting platform 3. Then, the cylinder 14 retracts its output end, which drives the pressure plate 4 to press down the metal plate handle. Handles are fixed on all four mounting platforms 3. Then, the external wire drawing assembly is activated to draw the surface of the handle above one of the mounting platforms 3. After the wire drawing is completed, the motor above the workbench 1 drives the rotating plate 2 to rotate. The rotating plate 2 rotates the wire-drawn handle to the side where the air duct 6 is installed. The air duct 6 is connected to the external compressed air pipe. The handles that have not been wire-drawn are rotated by the rotating plate 2 to the corresponding work position of the wire drawing assembly. This process is repeated.
[0020] The air duct 6 blows through the surface of the brushed handles, removing any metal debris. Cylinder 2 10 moves the air duct 6, blowing the handles from a distance to ensure a thorough cleaning. During blowing, to prevent debris from splashing onto the handles of other mounting platforms 3, a baffle 5 blocks any flying debris. The debris falls into the waste inlet 15 and exits through the rotating plate 2, preventing excessive accumulation on the rotating plate 2. After blowing, the motor restarts, moving the brushed handles under the grinding wheel 8. Similarly, another set of brushed handles is moved to the position of the air duct 6. Cylinder 1 9 starts, pressing the grinding wheel 8 down onto the handle surface. Then, motor 11 starts, rotating the screw 12. The screw 12 moves the slider 16. To ensure the slider 16 moves in the direction of the slide groove 13, the fixing rod 17 moves inside the slide groove 13. The slider 16 drives the connecting rod 7 to move, the connecting rod 7 drives the cylinder 9 to move, and the cylinder 9 drives the grinding wheel 8 to slide on the handle surface and grind the handle surface, smoothing out the metal barbs and sharp brushed protrusions on the handle surface.
[0021] The handles on the four mounting platforms 3 are used in sequence for wire drawing, blowing and polishing, allowing multiple processes to be carried out simultaneously and improving work efficiency.
[0022] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
