[0039] It should be noted that the terms "center," "upper," "lower," "front," "back," "left," "right," "inner," and "outer" used herein to indicate positions or locations are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, "plurality" means two or more.

[0040] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0041] like Figures 1 to 4 As shown, this embodiment provides a clamping mechanism and a mechanical device with the clamping mechanism. Figure 1 and Figure 3As shown, the design of the clamping mechanism adopts a modular structure, including a clamping device and a lifting device 5 located at the bottom of the clamping device, wherein the clamping device includes a lateral control component 1 and a vertical control component 2 movably connected to one side of the lateral control component 1, and the lateral control component 1 can control the lateral movement of the vertical control component 2; the vertical control component 2 is responsible for realizing the vertical lifting and pushing of the box. It can be vertically positioned after being moved horizontally into place through the connection with the lateral control component 1.

[0042] The bottom of the vertical control assembly 2 is movably connected to a pusher 3. Driven by the vertical control assembly 2, the pusher 3 can move linearly upward or downward, as well as push forward or backward. Through the coordinated operation of the horizontal control assembly 1 and the vertical control assembly 2, a secure clamping of the box can be achieved.

[0043] The pusher 3 can bear the weight of the box and maintain stability during the pushing process, preventing the box from tilting or sliding during the movement. The bottom of the pusher 3 is fixedly connected to the clamping claw assembly 4, which is in direct contact with the box. The movement of the pusher 3 can drive the movement of the clamping claw assembly 4.

[0044] like Figure 1 and 2 As shown, the clamping jaw assembly 4 of this embodiment includes a fixed clamping jaw 41, a driving assembly 42, and a movable clamping jaw 43. A slide bar is provided at the bottom of the pushing member, and the movable clamping jaw 43 is arranged around the outer periphery of the slide bar and is movably connected to the pushing member 3. The driving assembly 42 is located on one side of the pushing member 3 and is used to drive the movement of the movable clamping jaw 43. The fixed clamping jaw 41 is fixedly connected to the side of the pushing member 3 away from the driving assembly 42. The movable clamping jaw 43 and the fixed clamping jaw 41 are provided with multiple rows of slots for clamping objects. The provision of the slots increases the friction between the clamping jaw assembly 4 and the objects, preventing the objects from slipping during the movement of the clamping jaw assembly 4. By adjusting the distance between the movable clamping jaw 43 and the fixed clamping jaw 41 according to the size of the box, the clamping mechanism can adapt to boxes of different sizes and weights to achieve the best clamping effect.

[0045] In this embodiment, both the fixed jaw 41 and the movable jaw 43 are provided with hooks at their bases. The jaws and hooks are fixedly connected to form an L-shape, thereby preventing the gripped object from falling off during handling. The jaw assembly 4 of this embodiment may also be equipped with sensing components such as pressure sensors, micro switches, visual sensors, or fiber optic sensors to help the jaw assembly 4 more accurately grip objects.

[0049] Transmission assembly B23 is located at the top of stopper B22 and connected to moving member 21. Transmission assembly B23 includes motor B and reducer B. Both motor B and reducer B are fixedly connected to the top of stopper B22 via screws. Motor B is used to drive moving member 21 to move vertically on positioning plate B. Reducer B is used to increase the torque output of motor B, ensuring that moving member 21 can move smoothly and accurately.

[0050] like Figure 1 and 2 As shown, the moving part 21 includes a moving block 212, a connecting frame 215, a stopper C213 and a transmission component C214; the moving block 212 is arranged around the periphery of the positioning plate B; the connecting frame 215 is fixedly connected to the moving block 212 on the side, and the stopper C213 is fixedly connected to the bottom of the connecting frame 215, and the stopper C213 and the stopper B22 are vertically distributed; the bottom of the stopper C213 is screwed with a positioning plate C, and a gap is provided between the positioning plate C and the stopper C213, and the pushing member 3 is arranged around the periphery of the positioning plate C.

[0051] Transmission assembly C214 is located on the side of stopper C213 away from connecting frame 215 and is connected to pusher 3. Transmission assembly C214 includes a motor C and a reducer C. Both motor C and reducer C are screwed to the left side of stopper C213. Motor C is used to drive pusher 3 to move back and forth on positioning plate C. Reducer C is used to increase the torque output of motor C to ensure smooth movement of pusher 3.

[0052] The pushing member 3 includes a fixed block 31 and a fixed ring plate 32 fixedly connected to the top of the fixed block 31 ; the fixed ring plate 32 is arranged around the outer periphery of the positioning plate C.

The driver 521 can be a hydraulic driver 521, a pneumatic driver 521 or an electric driver 521, which is used to drive the lifting movement of the lifting frame 522. The lifting frame 522 of this embodiment is in a well shape.

[0057] like Figure 4 As shown, a mechanical device with a clamping mechanism, such as a carton unpacker, is provided at the front end of the carton unpacker in this embodiment. The conveyor paths are provided with multiple rollers. A control system for regulating the operation of various devices and components is provided at the bottom of the carton unpacker, and a control button for controlling the power switch is provided on the left side. A cutting mechanism and a clamping mechanism are provided in the middle of the carton unpacker. The cutting mechanism is located at the top of the left conveyor path. The left conveyor path is used to convey cartons to the bottom of the cutting mechanism. After the cutting machine cuts the cartons, the clamping mechanism clamps the cartons on the left conveyor path to the right conveyor path. The cartons are then transported back to the front end of the carton unpacker by the right conveyor path. A lifting assembly 52 is provided in the middle of each conveyor path to facilitate the cutting and clamping of different types of cartons. By adopting the above technical solution, the carton unpacker can handle cartons of various sizes and shapes, increasing the applicability of the machine and reducing labor costs.
