[0022] Reference Figure 1-2 The clamping mechanism of the automatic flat spraying flap machine includes two conveyor connecting plates 16, which are symmetrically parallel to each other and are respectively fixedly installed on fixed brackets between conveyor rollers of a narrow space, and the two conveyor connecting plates 16 are connected by a fixed rod, and a rotating shaft 12 is rotatably installed between the upper ends of the two conveyor connecting plates 16, and two mutually parallel flip frames are installed at both ends of the rotating shaft 12, and the two flip frames are respectively close to the inner end faces of the two conveyor connecting plates 16, and are used to install the two flip frames on both sides of the conveyor;

[0023] A driving shaft 15 is rotatably installed between the conveyor connecting plates 16. The driving shaft 15 is installed parallel to the lower part of the rotating shaft 12. Two gears 14 are fixedly installed on the driving shaft 15. Chain rings 13 are installed between the two gears 14 and the two flip sprockets 1. The inner rings of the chain rings 13 are respectively meshed with the gears 14 and several gear teeth 2 on the periphery of the flip sprocket 1 in the flip frame plate. A steering gear is fixedly installed on the conveyor, and the output shaft of the steering gear is fixedly connected to the driving shaft 15 through a coupling, that is, the driving shaft 15 and the two gears 14 are driven to rotate synchronously within a preset angle range through the steering gear output shaft, and the two flip frames are synchronously driven to flip through the two chain rings 13.

[0024] In this embodiment, the flip frame also includes a fixed flip frame 4, which is "U"-shaped as a whole and is fixedly installed on one side of the flip sprocket 1 by bolts. A plurality of gear teeth 2 are arranged in an arc shape with the central axis of the flip sprocket 1 as the center and are fixedly installed on the periphery of the flip sprocket 1 at equal intervals. A rotating hole 3 is provided on the central axis of the flip sprocket 1, and a rotating shaft 12 is fixedly installed in the rotating hole 3. Two fixed frame plates 7 are symmetrically installed on the fixed flip frame 4, and two clamping devices are symmetrically installed on the upper and lower sides of the fixed flip frame 4, respectively. The clamping device includes a cylinder 8 and a right-angle transmission member;

[0025] The bases in the two cylinders 8 are hinged to the ends of the two fixed frame plates 7, and the right-angle transmission parts include two "L"-shaped rotating rods 6, a connecting rod 10 and a clamping strip 11. The end of the piston rod in the cylinder 8 is rotatably connected to the end of an "L"-shaped rotating rod 6. The two "L"-shaped rotating rods 6 are parallel to each other, and the connecting rod 10, the clamping strip 11 and the fixed turning frame 4 are parallel to each other, that is, a deformable parallelogram structure is formed between the two "L"-shaped rotating rods 6, the connecting rod 10 and the fixed turning frame 4, that is, the parallelogram structure is deformed by the extension and contraction of the piston rod in the cylinder 8;

[0026] The two ends of the connecting rod 10 are respectively connected to the ends of the two "L"-shaped rotating rods 6. Two inner spiral cylinders 9 are arranged between the two "L"-shaped rotating rods 6 and the two ends of the connecting rod 10. The head end of the inner spiral cylinder 9 is hinged to the end of the "L"-shaped rotating rod 6. The inner spiral cylinder 9 and the two ends of the connecting rod 10 are threadedly connected to facilitate the installation and replacement of the connecting rod 10. The two ends of the clamping strip 11 are respectively connected to the head ends of the two "L"-shaped rotating rods 6 through the fixing plate 5. The head end of the fixing plate 5 and the head end of the "L"-shaped rotating rod 6 are rotated between the fixing plate 5 and the head end of the "L"-shaped rotating rod 6. The two "L"-shaped rotating rods 6 are rotatably connected to each other, and the middle ends of the two "L"-shaped rotating rods 6 are synchronously rotated to drive the two fixed plates 5 to pull the clamping strip 11 to move back and forth along one side of the fixed turning frame 4. When the two clamping strips 11 in the two symmetrical clamping devices are close to each other, they are used to clamp the sprayed plate.

[0027] In the utility model, the use process of the clamping mechanism of the automatic flat spraying flap machine is as follows:

[0028] 1) Plastic, wood, metal and other plates are automatically conveyed by a conveyor to a preset area on the conveyor where the clamping mechanism of the automatic flat spraying flipping machine is installed. Before the clamping mechanism of the automatic flat spraying flipping machine clamps and flips the above plates, the upper two clamping bars 11 and the lower two clamping bars 11 in the clamping mechanism of the automatic flat spraying flipping machine are away from each other and parallel to each other on the conveying surface of the conveyor, and are respectively located on the upper and lower sides of the above plates.

[0029] 2) After the plate reaches the preset position between the four clamping bars 11, the piston rods in the four cylinders 8 are extended synchronously, and the eight "L"-shaped rotating rods 6 are pushed to deform at the same time. The eight fixed plates 5 drive the upper two clamping bars 11 and the lower two clamping bars 11 to approach each other, so as to clamp and fix the plate that has reached the preset position.

[0030] 3) After clamping the plate, the output shaft of the servo drives the drive shaft 15 and the two gears 14 to rotate counterclockwise within a preset angle range, and through the two chain rings 13, the two flip frames are synchronously driven to flip the plate, and the plate is erected to facilitate the subsequent automatic spraying machine to spray.

[0031] In summary, the clamping mechanism of the automatic flat spray flipping machine has a more compact structure and can be installed between the conveyor rollers in a narrow space, saving installation space. The present application combines and connects the existing conveyor and flipping machine, saving the application of basic materials and the docking and debugging process between the conveyor and the flipping machine. The up and down movement of the clamping bar 11 is achieved through the upper and lower four cylinders 8 and four right-angle transmission parts, thereby achieving the clamping of the plate, and the driving shaft 15 and the two gears 14 are driven by the servo to rotate counterclockwise within a preset angle range to achieve the flipping operation of the workpiece.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
