AI Technical Summary
During the flip of rice bags, the rice tends to flow towards the direction of gravity, resulting in an imbalance in the center of gravity and shape of the rice bag, causing the rice bag to fall off from the claw clips of the rice bag, increasing the handling cost.
A rice bag jaw is designed, including an adapter seat, a jaw mechanism, a pressing mechanism and a clamping mechanism. The rice bag is grabbed through the jaw mechanism. The lifting drive part of the pressing mechanism drives the pressure bag to squeeze the rice bag. The scissor assembly of the clamping mechanism follows the point of the clamping mechanism to pull the clamping plate close to the grab position under the guidance of the guide assembly, so as to seal the rice bag and avoid falling off during the flip.
Effectively prevent the rice bag from falling off during flipping, reducing the cost of the rice bag handling.

[0035] like Figures 1 to 2As shown, there are two groups of material pressing mechanisms 30, and the two groups of material pressing mechanisms 30 are respectively arranged corresponding to the positions of each clamping mechanism 20. Specifically, the material pressing mechanism 30 includes a lifting drive member 31 and a bag pressing member 32. The lifting drive member 31 is a cylinder and is connected to the adapter 10 to drive the bag pressing member 32 to approach or move away from the grabbing position 11, thereby fixing the rice bag at the grabbing position 11. Furthermore, the bag pressing member 32 includes a support bar 321 and a buffer member 322. The support bar 321 is connected to the lifting drive member 31, and the buffer member 322 is connected to the support bar 321 to increase the contact area between the bag pressing member 32 and the rice bag, thereby improving the fixing strength of the rice bag.
[0036] like Figures 2 to 4 As shown, the material clamping mechanism 40 includes a scissors-fork assembly 41, a guide assembly 42 and a splint 43, wherein the scissors-fork assembly 41 is installed on the adapter 10 and is connected to the bag pressing part 32, the scissors-fork assembly 41 has a follower point 411, the guide assembly 42 is installed on the bag pressing part 32 and is connected to the splint 43, the splint 43 is connected to the follower point 411 of the scissors-fork assembly 41, when the lifting drive 31 drives the bag pressing part 32 to approach the grabbing position 11, the follower point 411 approaches the grabbing position 11, and when the lifting drive 31 drives the bag pressing part 32 away from the grabbing position 11, the follower point 411 is away from the grabbing position 11.
[0037] Specifically, if Figures 3 and 4 As shown, the scissor assembly 41 includes a first fixing member 412, a first scissor arm 413, a second scissor arm 414 and a second fixing member 415 that are sequentially connected and rotated. The first fixing member 412 is mounted on the adapter 10, and the second fixing member 415 is mounted on the support bar 321 of the bag pressing member 32. The connection between the first scissor arm 413 and the second scissor arm 414 forms a follower point 411. The guide assembly 42 includes a guide rail 421, a slider 422 and an adapter 423. The guide rail 421 is mounted on the bag pressing member 32, the slider 422 is slidably connected to the guide rail 421, and the adapter 423 is mounted on the slider 422. And it is connected to the splint 43. The adapter 423 includes an adapter plate 424, an extension plate 425 and a connecting plate 426. The adapter plate 424 is connected to the slider 422. There are two extension plates 425. The two extension plates 425 are respectively arranged on both sides of the adapter plate 424.

[0038] Understandably, in order to fully seal the rice bags, e.g. Figure 4As shown, the number of the clamping mechanisms 40 corresponds to the number of the pressing mechanisms 30, that is, each group of pressing mechanisms 30 corresponds to two groups of clamping mechanisms 40, and the two groups of clamping mechanisms 40 are respectively arranged on both sides of each group of bag pressing parts 32, so that through the cooperation of the clamping mechanism 20 and the pressing mechanism 30, the rice bag is fully sealed to prevent the rice bag from escaping from the rice bag clamping jaws 100.
[0039] When the rice bag clamp 100 provided by the present application is in use: the gripping position 11 of the adapter 10 is controlled by a manipulator to overlap with the target rice bag, and then the gripping driving assembly 21 of each gripping mechanism 20 controls each hook claw 22 to grip the rice bag at the gripping position 11, and then the lifting driving member 31 of the pressing mechanism 30 controls the bag pressing member 32 to approach the gripping position 11, and cooperates with the hook claw 22 to squeeze the rice bag at the gripping position 11, and at the same time, the bag pressing member 32 drives the scissor assembly 41 of the clamping mechanism 40 to actuate, and uses the follow-up point 411 of the scissor assembly 41 to pull the splint 43, so that the splint 43 is close to the gripping position 11 under the guidance of the guide assembly 42, thereby achieving the purpose of sealing the rice bag at the gripping position 11, preventing the rice bag from detaching from the rice bag claw clamp during the flipping action, so as to avoid damage to the rice bag and achieve the purpose of reducing the handling cost of the rice bag.
[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
