[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses an automatic clamping device. Figure 1 and Figure 2An automatic clamping device includes a frame 1 and a mounting frame 2. The mounting frame 2 is fixed to the frame 1 and is tilted. The frame 1 rotatably carries a horizontal conveyor belt 3 and an oblique conveyor belt 4. The horizontal conveyor belt 3 is provided with a feed end and a discharge end. The oblique conveyor belt 4 is located above and to one side of the discharge end of the horizontal conveyor belt 3. The oblique conveyor belt 4 is tilted upward from the discharge end of the horizontal conveyor belt 3 toward a direction away from the feed end. The tilt direction of the mounting frame 2 is consistent with the tilt direction of the oblique conveyor belt 4. The mounting frame 2 is provided with a drive cylinder 5, a sprocket 63 assembly 6, and a clamping assembly 7. The drive cylinder 5 is mounted on the mounting frame 2 and is tilted. The tilt direction of the drive cylinder 5 is consistent with the tilt direction of the mounting frame 2. The piston rod of the drive cylinder 5 is tilted upward, and the sprocket 63 assembly 6 is fixedly connected to the piston rod of the drive cylinder 5. The movement of the piston rod of the drive cylinder 5 drives the movement of the sprocket 63 assembly 6. The sprocket 63 assembly 6 is connected to the clamping assembly 7, and the clamping assembly 7 is slidingly connected to the mounting frame 2. The movement of the sprocket 63 assembly 6 drives the clamping assembly 7 to slide along the tilt direction of the mounting frame 2. The clamping assembly 7 clamps the material on the horizontal conveyor belt 3. The piston rod of the drive cylinder 5 retracts, causing the clamping assembly 7 to clamp the material away from the horizontal conveyor belt 3. When the material gradually moves away from the horizontal conveyor belt 3 and approaches the diagonal conveyor belt 4, the clamping assembly 7 releases the material, allowing the material to be transferred to the diagonal conveyor belt 4.

[0029] Specifically, the clamping assembly 7 includes a fixed frame 71, a control cylinder 72, a connecting block 73, a connecting bar 74, and a clamping plate 75. The fixed frame 71 is arranged at an angle. A guide groove 8 is provided on the mounting frame 2. The length direction of the guide groove 8 is consistent with the length direction of the mounting frame 2. The side edges of the fixed frame 71 are accommodated in the guide groove 8 and abut against the groove wall of the guide groove 8. The fixed frame 71 and the mounting frame 2 are slidingly connected through the guide groove 8. The sprocket 63 assembly 6 is fixedly connected to the fixed frame 71. There are two control cylinders 72, which are arranged side by side and are both fixed to the fixed frame 71. The connecting block 73 is arranged in a U shape. The two connecting blocks 73 are respectively hinged to the piston rods of the two control cylinders 72. There are two corresponding connecting bars 74. The open ends of the two connecting blocks 73 are respectively hinged to one end of the two connecting bars 74. The ends of the two connecting bars 74 are respectively accommodated in the U-shaped grooves of the two connecting blocks 73. The connecting strip 74 is bent, and two corresponding clamping plates 75 are provided. The other ends of the two connecting strips 74 are fixedly connected to the opposite ends of the two clamping plates 75. Four connecting seats 9 are fixed to the fixing frame 71. The bent ends of the two connecting strips 74 are rotatably connected to the two connecting seats 9. The ends of the two clamping plates 75 that are not fixed to the connecting strip 74 are rotatably connected to the other two connecting seats 9.

[0030] Correspondingly, when the material needs to be transferred, the piston rod of the driving cylinder 5 moves to drive the sprocket 63 assembly 6 to move, and the movement of the sprocket 63 assembly 6 drives the fixed frame 71 to move along the groove wall of the guide groove 8 so that the clamping plate 75 approaches the material on the horizontal conveyor belt 3. When the clamping plate 75 approaches the material on the horizontal conveyor belt 3, the piston rod of the control cylinder 72 moves to drive the connecting block 73 to move, and the movement of the connecting block 73 drives the connecting bar 74 to rotate. The rotation of the connecting bar 74 drives the clamping plate 75 to rotate a certain angle. The two clamping plates 75 rotate together at a certain angle so as to approach each other and clamp the material.

[0031] In addition, the clamping plate 75 is provided with ridges 10. The provision of the ridges 10 increases the friction between the material and the clamping plate 75 when the clamping plate 75 clamps the material, making the clamping and transfer process more stable.

[0032] Furthermore, a mounting plate 11 is fixed to the mounting frame 2, and the mounting plate 11 is horizontally fixed to the middle section of the mounting frame 2. The driving cylinder 5 is fixedly connected to the mounting plate 11. The sprocket 63 assembly 6 is installed between the mounting plate 11 and the fixed frame 71. The sprocket 63 assembly 6 includes a chain 61, a connecting rod 62, and a sprocket 63. One end of the chain 61 is fixedly connected to the mounting plate 11, and the other end of the chain 61 is fixedly connected to the fixed frame 71. The bottom of the connecting rod 62 is fixedly connected to the piston rod of the driving cylinder 5, and the piston rod of the driving cylinder 5 supports the connecting rod 62. Two sprockets 63 are provided, and the two sprockets 63 are rotatably connected to the two ends of the connecting rod 62 respectively. The chain 61 is engaged with the sprocket 63, and the sprocket 63 supports the chain 61. The telescopic movement of the piston rod of the driving cylinder 5 drives the connecting rod 62 to move up and down, and the movement of the connecting rod 62 drives the sprocket 63 to move. The sprocket 63 and the chain 61 move relative to each other. The fixed frame 71 slides with the mounting frame 2 under the action of gravity, causing the fixed frame 71 to move close to the horizontal conveyor belt 3.

[0033] Furthermore, the driving cylinder 5 is mounted on the mounting frame 2 through a rotating member 12. Specifically, the rotating member 12 includes a mounting seat 121, a mounting block 122 and a rotating rod 123. The mounting seat 121 is fixedly connected to the mounting frame 2, the mounting block 122 is fixedly connected to the end of the driving cylinder 5, and the rotating rod 123 movably passes through the mounting seat 121 and is rotatably carried on the mounting block 122. Before fixing the driving cylinder 5, the operator can rotate the driving cylinder 5 to a suitable inclination angle and then fix the driving cylinder 5 to achieve a better clamping and transfer effect on the material. A connecting rod 13 is fixed between the mounting plate 11 and the mounting frame 2. The connecting rod 13 is arranged parallel to the mounting frame 2. By setting the connecting rod 13, the vibration of the mounting frame 2 during the operation of the clamping device is reduced, thereby improving stability.

[0034] The implementation principle of an automatic clamping device in the embodiment of the present application is as follows:

[0035] When material needs to be transferred, the piston rod of the drive cylinder 5 telescopically moves, driving the connecting rod 62 to move upward and downward. The movement of the connecting rod 62 drives the sprocket 63 to move. The sprocket 63 and the chain 61 move relative to each other, and the fixed frame 71, under the action of gravity, slides against the mounting frame 2, causing the fixed frame 71 to move closer to the horizontal conveyor belt 3. When the clamping plate 75 approaches the material on the horizontal conveyor belt 3, the piston rod of the control cylinder 72 moves, driving the connecting block 73 to move. The movement of the connecting block 73 drives the connecting bar 74 to rotate. The rotation of the connecting bar 74 drives the clamping plate 75 to rotate a certain angle. The two clamping plates 75 rotate together a certain angle, approaching each other and clamping the material. The transmission through the sprocket 63 and chain 61 reduces the pulling effect of the fixed frame 71 on the drive cylinder 5, thereby reducing damage to the piston rod of the drive cylinder 5, extending the service life of the clamping device, and reducing maintenance costs.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
