[0013] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0014] See also Figure 1-Figure 3 The centering clamp for the intelligent clamping device shown in the figure comprises a support part 10, a central clamping part 20 and a side clamping part 30. The central clamping part 20 is mounted on the support part 10, and a pair of side clamping parts 30 are mounted on both sides of the support part 10, and the central clamping part 20 and the side clamping part 30 clamp the material 40 together, and the support part 10 connects the entire clamp to the upper actuating part of the intelligent packaging device.

[0015] The supporting part 10 comprises a mounting plate 11, a transverse sliding groove 12, a screw rod 13, a vertical sliding groove 14 and a support arm 15. The mounting plate 11 is provided with a pair of connecting holes 111, and the connecting holes 111 connect the whole device with the actuating part of the upper part. Of course, according to the different specific connection forms of the upper actuating part, the connecting holes 111 can also be replaced by a matching method. The mounting plate 11 is connected with the transverse sliding groove 12, and the screw rod 13 is installed in the middle of the transverse sliding groove 12. The lower control block 24 of the central clamping part 20 is slidably installed in the transverse sliding groove 12. The rear part of the transverse sliding groove 12 is connected with the vertical sliding groove 14 in the vertical direction, and the central clamping part 20 is slidably installed in the vertical sliding groove 14. A support arm 15 extends from each side of the mounting plate 11, and the side clamping part 30 is installed on the support arm 15. The front end of the support arm 15 is provided with an ear piece 151, and the ear piece 151 is hinged to the hinge hole 32 of the side clamping part 30.

[0016] The central clamping part 20 includes a control panel 21, a vertical slider 22, a first clamping wheel 23 and a lower control block 24. The control panel 21 has side slopes 211 on both sides, and the side slopes 211 control the movement of the side clamping part 30. The control panel 21 has a lower slope 212 at the bottom, and the lower slope 212 controls the movement of the central clamping part 20. The angle relationship between the side slope 211 and the lower slope 212 needs to be designed to cooperate with each other so that the three clamping wheels 23 move toward the center synchronously to achieve centering clamping. The design of the angle relationship can be easily calculated based on the angle relationship. The control panel 21 has a vertical slider 22 on the back, which is fitted in the vertical slide groove 14. The vertical slider 22 drives the control panel 21 to move up and down in the vertical slide groove 14. A first clamping wheel 23 is installed on the top of the control panel 21. The first clamping wheel 23 clamps the material 40 from below. The control panel 21 has a lower control block 24 at the bottom, which is slidably installed in the horizontal slide groove 12. The lower control block 24 resists the lower inclined surface 212 of the control block 21 from below, and the lower control block 24 slides left and right in the horizontal slide groove 12. The lower inclined surface 212 pushes the control plate 21 to slide up and down to realize the up and down movement of the first clamping wheel 23. The bottom of the lower control block 24 has a lower sliding block 241, and the lower sliding block 241 is installed in the horizontal sliding groove 12. The middle of the lower sliding block 241 has a threaded hole 242, and the threaded hole 242 is docked with the screw 13. The screw 13 is rotated to drive the lower control block 24 to slide in the horizontal sliding groove 12. The power source of the screw 13 can be selected according to the required power size and the space size at that place. Suitable power sources, such as servo motors and other rotating power sources, can be selected.

[0017] The side clamping portion 30 includes an upper arm 31, a hinge hole 32, a second clamping wheel 33, a lower arm 34, a pull rod 35 and an elastic band 36. The hinge hole 32 is provided between the upper arm 31 and the lower arm 34. The angle between the upper arm 31 and the lower arm 34 is greater than 100 degrees, providing enough space in the middle for accommodating the material 40. The hinge hole 32 is hinged to the ear piece 151. The second clamping wheel 33 is installed at the upper end of the upper arm 31. The second clamping wheel 33 clamps the material 40 from the upper side of the material. The lower arm 34 is installed at the bottom. The roller is close to the side slope 211 of the control panel 21, and moves with the movement of the side slope 211 to realize the rotation of the side clamping part 30 around the hinge hole 32. The bottom of the lower arm 34 has a pull rod 35, and the pull rods 35 at the bottom of the two side clamping parts 30 are connected with an elastic band 36. Under the action of the elastic band 36, the two second clamping wheels 33 always have a tendency to open outward. At the same time, the two rollers always have a clamping pressure on the control panel 21, and the clamping pressure makes the control panel 21 always have a tendency to move downward.

[0018] The working principle of the present invention is: the power source drives the lower control block 24 to move left and right, according to the attached Figure 2In the position shown, when the lower control block 24 moves to the right, the control plate 21 moves upward, and the first clamping wheel 23 moves upward accordingly. At the same time, under the action of the side slope 211 of the lower control block 24, the lower arm 34 overcomes the resistance of the elastic band 36 and opens outward. Accordingly, the upper arm 31 swings inward, and the second clamping wheel 33 approaches the material 40 until the material 40 is clamped. When the lower control block 24 moves to the left, the control plate 21 moves downward, the first clamping wheel 23 moves downward, and under the action of the elastic band 36, the lower arm 34 contracts inward, and then the second clamping wheel 33 releases the material 40.

[0019] The above embodiments mainly illustrate the centering clamp for the intelligent clamping device of the present invention. Although only limited embodiments and technical features are described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its subject matter and scope. Therefore, the embodiments shown are regarded as illustrative rather than restrictive, and the present invention may cover various modifications and replacement schemes without departing from the spirit and scope of the present invention as defined in the appended claims.
