Description

Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a gripper for automatically adjusting a pressure handle. Background Art

[0002] Vacuum-packed rice bags are usually stacked up and down when packed. To prevent the rice bags from shaking in the packaging box, the length of the packaging box is usually slightly smaller than the length of the rice bag. As a result, the handles of the stacked rice bags overlap each other during packing. Multiple stacked handles will exceed the inner height of the packaging box, affecting the sealing of the packaging box.

[0003] Existing packing equipment generally adopts a cross-placement method to solve this problem, that is, the gripper of the packing equipment rotates 180° so that the rice bag is placed crosswise with the previous rice bag head to tail. However, this packing method makes it difficult to place the rice bags neatly and uniformly.

[0004] In addition, the gripper in this method can generally only use one pressure handle to bend one rice bag at a time, which is inefficient. If multiple pressure handles are used to move multiple rice bags at the same time, in order to adapt to rice bags of different sizes, it is necessary to manually adjust the position of each pressure handle and the distance between them, which will still affect the efficiency of rice packaging. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a gripper with automatically adjustable pressure handles, which can use two pressure handles at the same time to automatically bend the handles of two rice bags, and can automatically adjust the position of the pressure handles according to the length of the rice bags, thereby reducing manual operations and improving the efficiency of rice packaging.

[0006] According to one aspect of the utility model, there is provided a gripper for automatically adjusting a pressure-lifting handle, comprising a rotating arm, two first lifting cylinders are respectively installed at the bottom of the left and right sides of the rotating arm, the bottoms of the two first lifting cylinders are respectively connected to two mounting frames, the bottoms of the two mounting frames are respectively provided with two suction cups, and the left sides of the two mounting frames are respectively connected to two pressure-lifting handle components; wherein a first servo motor is installed on the left mounting frame, and the first servo motor is connected to the pressure-lifting handle component on the mounting frame through a horizontally arranged first screw rod.

[0007] In some embodiments, a connecting block is installed on the right mounting frame, and the left end of the connecting block is connected to the pressure handle component on the mounting frame. The advantage is that the pressure handle component can be connected to the right mounting frame through the connecting block.

[0008] In some embodiments, the handle pressing member comprises two vertical pressing rods. It is beneficial that the composition of the handle pressing member is described, which is used to press the handle of the rice bag.

[0009] In some embodiments, a movable baffle is further included, and the movable baffle is located on the right side of the suction cup on the right side. The benefit thereof is that the position of the rice bag on the right side can be adjusted by the movable baffle.

[0010] In some embodiments, a second servo motor is further included, and the second servo motor is connected to the movable baffle through a second horizontally arranged screw rod. The advantage is that the second servo motor and the second screw rod can make the movable baffle move left and right.

[0011] In some embodiments, the second screw rod is also connected to a second lifting cylinder. The advantage is that the height of the movable baffle, the second servo motor and the second screw rod can be adjusted by the second lifting cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1-3 As shown, the gripper includes a rotating arm 1, the middle top of which can be connected to a corresponding power rotating device, and two first lifting cylinders 2 are respectively installed at the bottom of both sides (set as the left and right sides) of the rotating arm 1, and the bottoms of the two first lifting cylinders 2 are respectively connected to two mounting frames 3, and the bottoms of the two mounting frames 3 are respectively provided with two suction cups 4, and two pressing handle components 5 are respectively connected to the left side of the two mounting frames 3. Among them, the suction cup 4 can be used to suck up the rice bag 14, and when the two first lifting cylinders 2 are in operation, they can drive the two mounting frames 3 and the two suction cups 4 to suck up the two rice bags 14.

[0018] A connecting block 8 is installed on the mounting frame 3 on one side (called the right side), and the handle pressing component 5 on the mounting frame is connected to the left end of the connecting block 8. When the suction cup 4 on this side is used to suck up the rice bag 14, the handle pressing component 5 can bend and press the handle of the rice bag 14.
