Abstract
Description
Technical Field
[0001] This application relates to a bag gripping structure, and more particularly to a bag gripping structure. Background Technology
[0002] In the fields of automated packaging and logistics transportation, the performance of material handling devices directly affects production efficiency and equipment operational stability. Traditionally, the gripping and transfer of packaging bags relies primarily on mechanical gripper structures, such as gripping mechanisms driven by cylinders, connecting rods, or motors. While these devices achieve bag gripping through the physical contact and displacement of mechanical components and possess a certain degree of reliability, they suffer from the following significant drawbacks:
[0003] Limited movement speed: Mechanical grippers rely on multiple power sources (such as pneumatic, hydraulic, or electric actuators) for coordinated drive, and their response time is limited by the physical inertia of the mechanical structure and transmission delay. Especially in high-speed production lines, the opening and closing cycle of the grippers is difficult to shorten further, resulting in a bottleneck in overall gripping efficiency.
[0004] High structural complexity: Traditional grippers require guide rails, limit devices, and redundant protection mechanisms to ensure gripping accuracy, resulting in bulky equipment and high maintenance costs. Furthermore, the complex mechanical connections are prone to failure due to long-term wear, affecting the equipment's lifespan. Utility Model Content

[0054] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0055] Example 1
[0056] Figures 1-2 This diagram illustrates a structural method for a bag-grabbing structure according to an embodiment of this application. Figures 1-2 As shown, the bag-grabbing structure may include:
[0057] Stand 100, which is mounted on an external mobile device;
[0058] Mounting base 200, which is mounted on bracket 100;
[0059] Connector 300 is mounted on mounting base 200;
[0060] Magnetic suction component 400 is disposed at connector 300;
[0061] The first adsorption element 500 is disposed on the connector 300;
[0062] The second adsorption element 600 is disposed on the magnetic adsorption assembly 400. The second adsorption element 600 corresponds to the first adsorption element 500. The magnetic adsorption assembly 400 drives the second adsorption element 600 and cooperates with the first adsorption element 500 to grip the packaging bag.
[0063] In this embodiment, the mounting base 200 is mounted on the external mobile device by the bracket 100, and the connector 300 fixes the first adsorption member 500 on the mounting base 200. The movement of the second adsorption member 600 is controlled by the magnetic adsorption component 400. The second adsorption member 600 cooperates with the first adsorption member 500 to clamp and move the packaging bag. The magnetic adsorption component 400 enables the first adsorption member 500 and the second adsorption member 600 to be adsorbed. Compared with traditional mechanical grippers, the movement speed is faster, the gripping speed is higher, the structure is simple, and it is easy to maintain.
[0064] like Figures 1-2 As shown, in one embodiment,
[0065] The magnetic assembly 400 includes:
[0066] Magnetic block 410 is disposed within the mounting base 200;
[0067] The movable block 420 is partially disposed within the mounting base 200, and the movable block 420 has a first state and a second state.
[0068] When the active block 420 is in the first state, the active block 420 is in contact with the magnetic block 410;
[0069] When the active block 420 is in the second state, the active block 420 is not in contact with the magnetic block 410;
[0070] Movable rod 430 is mounted on movable block 420, and second adsorption element 600 is mounted on the end of movable rod 430 away from movable block 420;
[0071] When the active block 420 is in the first state, both the second adsorption element 600 and the first adsorption element 500 are in contact with the packaging bag.
[0072] In this embodiment, the movable block 420 is made of iron and can be magnetically attracted to the magnetic block 410. When the movable block 420 moves into the attraction range of the magnetic block 410, the movable block 420 automatically moves toward the magnetic block 410 and drives the movable rod 430 to move so that the second adsorption member 600 and the first adsorption member 500 clamp the packaging bag.
[0073] Specifically, the first state of the movable block 420 is the clamping state, at which time the movable block 420 and the magnetic block 410 are magnetically attracted, and the first adsorption member 500 and the second adsorption member 600 clamp the packaging bag.
[0074] The first suction element 500 and the second suction element 600 are suction cups or elastic silicone heads to prevent slippage when clamping the packaging bag.
[0075] like Figures 1-2 As shown, in one embodiment,
[0076] The magnetic block 410 has a through hole 411, the diameter of which is larger than the diameter of the movable rod 430 but smaller than the diameter of the movable block 420.
[0077] In this embodiment, the diameter of the through hole 411 on the magnetic block 410 is larger than the diameter of the movable rod 430, ensuring that the movable rod 430 can pass through the magnetic block 410. The diameter of the through hole 411 on the magnetic block 410 is smaller than the diameter of the movable block 420, ensuring that the magnetic block 410 attracts the movable block 420, while limiting the range of motion of the movable block 420.
[0078] like Figures 1-2 As shown, in one embodiment,
[0079] The magnetic assembly 400 includes:
[0080] Guide block 440 is located on the side of mounting base 200 away from the first adsorption member 500, and the portion of movable block 420 located outside the mounting base 200 is located on guide block 440.
[0081] In this embodiment, the guide block 440 guides the movement trajectory of the movable block 420 to ensure the normal movement of the movable block 420 and avoid jamming. At the same time, the movable block 420 is mounted on the guide block 440 and moves along the guide block 440, thus providing support for the movable block 420.
[0082] like Figures 1-2 As shown, in one embodiment,
[0083] The magnetic assembly 400 also includes:
[0084] A fixed rod 450 is mounted on the movable block 420. By pulling the fixed rod 450, the movable block 420 can be switched from the first state to the second state.
[0085] In this embodiment, the movable block 420 can be pushed by the fixed rod 450 so that the movable block 420 enters the magnetic attraction range of the magnetic block 410. After the movable block 420 enters the magnetic attraction range of the magnetic block 410, it moves quickly toward the magnetic block 410. When the first adsorption member 500 and the second adsorption member 600 need to be separated, the movable block 420 is pulled by the fixed rod 450 to separate the movable block 420 from the magnetic block 410.
[0086] like Figures 1-2 As shown, in one embodiment,
[0087] The cross-section of connector 300 is an "L" shaped structure.
[0088] In this embodiment, the connector 300 is L-shaped to facilitate the placement of the first adsorption member 500, thereby ensuring that the first adsorption member 500 is placed on the opposite side of the mounting base 200 and corresponds to the position of the second adsorption member 600, so as to cooperate with the second adsorption member 600 to grasp the packaging bag.
[0089] like Figures 1-2 As shown, in one embodiment,
[0090] The magnetic assembly 400 also includes:
[0091] Limiting block 470 is located on the end of movable block 420 away from movable rod 430.
[0092] In this embodiment, the limiting block 470 is disposed on the movable block 420 away from the movable rod 430. The limiting block 470 is located outside the mounting base 200, limiting the movement trajectory of the movable block 420 and simultaneously limiting the position of the second limiting rod, preventing the movable block 420 from detaching from the base when the magnetic block 410 attracts it.
[0093] Specifically,
[0094] The mounting base 200 has a stop block 480, and the stop block 480 has a hole 481 for the movable block 420 to pass through. The diameter of the limiting block 470 is larger than the diameter of the hole 481.
[0095] The limiting block 470 is positioned outside the mounting base 200 by means of the hole 481.
[0096] Specifically, the limiting block 470 has sliders at both ends, and the guide block 440 has a groove that matches the sliders. The sliders slide in the groove, thus limiting the movement trajectory of the movable block 420.
[0097] like Figures 1-2 As shown, in one embodiment,
[0098] The fixed rod 450 and the movable block 420 have an "L" shaped cross section.
[0099] In this embodiment, the fixed rod 450 and the movable block 420 are arranged in an "L" shape, which facilitates the application of force to the fixed rod 450 from below the movable block 420, facilitates the pushing and pulling of the movable block 420, and thus facilitates the adsorption and separation of the movable block 420 and the magnetic block 410.
[0100] Example 2
[0101] like Figure 3 As shown, the difference between Embodiment 2 and Embodiment 1 is that the fixing rod 450 is replaced with an electromagnet 460. The electromagnet 460 is installed on the side of the guide block 440 outside the mounting base 200 away from the mounting base 200, and the magnetic block 410 is also replaced with an electromagnet 460.
[0102] Two electromagnets 460 drive the movable block 420 to switch between the first state and the second state. When it is necessary to switch to the first state, simply activate the magnetic block 410 in the mounting base 200, so that the mounting base 200 moves under the magnetic force of the magnetic block 410, so that the second adsorption member 600 clamps the first adsorption member 500.
[0103] When it is necessary to switch to the second state, simply activate the electromagnet 460 outside the mounting base 200, causing the mounting base 200 to move outward under the action of the electromagnet 460, thereby separating the second adsorption member 600 from the first adsorption member 500.
[0104] The functions of each module in each device of this utility model embodiment can be found in the corresponding description in the above method, and will not be repeated here.
[0105] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of those different embodiments or examples.
[0106] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0107] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
