The movement direction of the connecting plate 13 is close to or away from the connecting block 11. The two clamping jaws 2 are respectively fixed on the connecting block 11 and the connecting plate 13. A driving member 3 for driving the connecting plate 13 to move is provided on the base 1;

[0015] A travel switch 14 is provided on the side of the base 1, a touch plate 15 is provided on the connecting plate 13, the touch plate 15 and the travel switch 14 are aligned, the driving member 3 is provided with a controller, and the travel switch 14 and the controller are electrically connected.

[0016] The utility model aims at the need to feed two rollers on a machine tool at the same time, and the process is as follows: according to the distance between the two rollers, the driving member 3 drives the connecting plate 13 to move on the linear guide rail 12, so as to adjust the distance between the two clamping jaws 2, so that the distance between the two clamping jaws 2 corresponds to the distance between the two rollers, and then the two clamping jaws 2 are brought close to the two rollers, and the two clamping jaws 2 respectively clamp the two rollers, so as to realize feeding the two rollers to the machine tool at the same time.

[0017] In the present invention, when adjusting the distance between the two clamping jaws 2 , the touch plate 15 is in contact with the travel switch 14 , so that the distance between the two clamping jaws 2 can be precisely controlled.

[0018] In the utility model, as a preferred solution, the above-mentioned driving member 3 includes a rotating motor 31 and an adjusting nut 32 arranged on the connecting plate 13. The rotating motor 31 is arranged on the base 1. The output end of the rotating motor 31 is provided with an adjusting screw 4. The bottom of the other end of the base 1 is provided with a fixing nut 41. The fixing nut 41 and the connecting block 11 are relatively arranged at the bottom of the base 1. The adjusting screw 4 is threadedly connected to the adjusting nut 32 and the fixing nut 41 in sequence.

[0019] In the present invention, the movement of the connecting plate 13 is driven by the rotating motor 31 , and the connecting plate 13 is driven to move on the linear guide rail 12 through the action of the adjusting screw rod 4 and the adjusting nut 32 .

[0020] In the present invention, as a preferred solution, two sliders 42 are provided on the connecting plate 13 , the adjusting nut 32 is located between the two sliders 42 , and the slider 42 is slidably disposed on the linear guide rail 12 .

[0021] In the present invention, the arrangement of the slider 42 ensures the stability of the movement of the connecting plate 13 on the linear guide rail 12 .

[0022] In the utility model, as a preferred embodiment, the above-mentioned clamping jaw 2 includes a fixed block 21 and two clamping plates 22 arranged on the connecting block 11 or the connecting plate 13, a clamping jaw cylinder 5 is provided on the fixed block 21, and two guide blocks 51 are provided at the output end of the clamping jaw cylinder 5. The two guide blocks 51 are slidably arranged at the bottom of the fixed block 21, a V-shaped plate 52 is provided on the side of the fixed block 21, and the two oblique sides of the V-shaped plate 52 are provided with guide rails 53, and the guide blocks 51 are provided with intermediate blocks 54 that can slide up and down, and the intermediate blocks 54 are provided with guide sliders 55 that can slide on the guide rails 53, and the two clamping jaws 2 are respectively vertically fixed at the bottom of the intermediate blocks 54.

[0023] In the utility model, the clamping jaw 2 clamps or releases the roller with the clamping jaw cylinder 5 as the power. Taking the clamping jaw 2 clamping the roller as an example, by driving the two guide blocks 51 to move relative to each other, as the distance between the two guide blocks 51 shortens, the guide slider 55 moves along the extension direction of the guide rail 53, that is, moves toward the tip of the V-shaped plate 52. During this process, the middle block 54 moves upward synchronously on the guide block 51. The coordinated movement of the two makes the clamping jaw 2 move upward synchronously when the clamping jaw 2 rolls, which is more conducive to the clamping jaw 2 to clamp the roller from the conveyor belt.
