Description

Technical Field

[0001] This utility model relates to suction cups, and more particularly to a universal suction cup for fruits and vegetables of various sizes. Background Technology

[0002] In modern agriculture and food processing, automated production lines are widely used in the sorting, cleaning, packaging, and transportation of fruits and vegetables. Among these, vacuum suction cups based on the principle of negative pressure adsorption have become one of the mainstream end-effectors for grasping fruits and vegetables on production lines due to their simple structure, convenient operation, and minimal damage to product surfaces. However, existing vacuum suction cups have significant shortcomings in compatibility and adaptability when handling fruits and vegetables of varying shapes and sizes, severely restricting the efficiency and stability of the production line, thus requiring improvement. Summary of the Invention

[0003] This invention addresses the shortcomings of existing suction cups, such as poor compatibility and adaptability, by providing a new universal suction cup for fruits and vegetables in multiple sizes.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A multi-size universal suction cup for fruits and vegetables includes a suction cup body, wherein the suction cup body includes a buffer part, and the buffer part has a pleated layered structure. A fixing part, located at the upper end of the buffer part, is used for a detachable and sealed connection with the vacuum drive device; The suction part is located at the lower end of the buffer part. The suction part has at least three layers of concentric rings nested in sequence. The fixing part, the buffer part and the suction part are integrally formed.

[0005] This application utilizes a multi-layered lip to enable the suction cup to grip fruits and vegetables of varying shapes and sizes, thereby effectively improving the suction cup's compatibility and adaptability.

[0006] Preferably, in the multi-size universal suction cup for fruits and vegetables described above, the lower end of the buffer portion forms a fixed edge, and the lip edge is disposed on the fixed edge.

[0007] Preferably, in the multi-size universal suction cup for fruits and vegetables described above, the length of the lip increases sequentially from the inside to the outside of the fixed edge, forming an inner edge, a middle edge, and an outer edge.

[0008] Preferably, in the above-described multi-size universal suction cup for fruits and vegetables, the inner diameter is 40 mm-50 mm, the middle diameter is 55 mm-65 mm, and the outer diameter is 70 mm-80 mm.

[0009] Preferably, in the multi-size universal suction cup for fruits and vegetables described above, the distance between adjacent lips is 2 mm to 3 mm.

[0010] Preferably, in the multi-size universal suction cup for fruits and vegetables described above, the lip edge has a structure that gradually narrows from wide to narrow, and the width becomes narrower the further away from the fixed edge.

[0011] Preferably, in the above-described multi-size universal suction cup for fruits and vegetables, the lip is made of a soft material.

[0012] The present invention has the following advantages through the above structural improvements: The suction cup of this application has the advantages of good compatibility and adaptability compared with conventional suction cups. In particular, by setting multiple layers of lips in the suction part with different diameters for each lip, the suction part can effectively avoid air leakage and insufficient suction force when gripping fruits and vegetables of different shapes and sizes, thereby effectively improving the compatibility and adaptability of the suction cup.

[0015] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a multi-size universal suction cup for fruits and vegetables includes a suction cup body 1, wherein the suction cup body 1 includes a buffer part 11, and the buffer part 11 has a pleated layered structure. The fixing part 12 is located at the upper end of the buffer part 11 and is used for detachable and sealed connection with the vacuum drive device. The suction part 13 is located at the lower end of the buffer part 11. The suction part 13 is provided with at least three layers of concentric rings nested in sequence. The fixing part 12, the buffer part 11 and the suction part 13 are integrally formed.

[0017] The fixing part 12 in this embodiment has a fixing groove to facilitate a detachable and sealed connection with the vacuum drive device. The multi-layer suction part 13 can effectively prevent air leakage and insufficient adsorption force. The suction part 13 in this embodiment has three layers, but in other embodiments the number of suction parts 13 may be increased or decreased.

[0018] Preferably, the lower end of the buffer portion 11 forms a fixed edge 111, and the lip 131 is disposed on the fixed edge 111.

[0019] Specifically, by setting the fixed edge 111, the number of lip edges 131 can be increased more effectively.

[0020] Preferably, the length of the lip 131 increases sequentially from the inside to the outside of the fixed edge 111 to form an inner edge 1311, a middle edge 1312, and an outer edge 1313.

[0021] Specifically, the inner edge 1311, the middle edge 1312, and the outer edge 1313 correspond to small, medium, and large fruits and vegetables, respectively. The inner edge 1311, the middle edge 1312, and the outer edge 1313 are only described in this embodiment. In another embodiment, the inner edge 1311, the middle edge 1312, and the outer edge 1313 may represent other edges 131 or increase the number of inner edges 1311, the middle edge 1312, and the outer edge 1313.

[0022] Preferably, the inner edge 1311 has a diameter of 40 mm to 50 mm, the middle edge 1312 has a diameter of 55 mm to 65 mm, and the outer edge 1313 has a diameter of 70 mm to 80 mm.

[0023] Furthermore, in this embodiment, setting the diameters of the inner edge 1311, the middle edge 1312, and the outer edge 1313 within the aforementioned range can effectively cover the size of the fruits and vegetables that this embodiment needs to grasp. In another embodiment, the fruits and vegetables may be larger or smaller, but the suction part 13 of the suction cup body 1 has good expandability or contractility, thereby effectively improving the compatibility and adaptability of the suction part 13.

[0024] Preferably, the spacing between adjacent lips 131 is 2 mm to 3 mm.

[0025] Specifically, the lip 131 set within this spacing range has a larger range when expanding or contracting, and will not affect the adhesion between adjacent lip 131 and fruits and vegetables when expanding or contracting.

[0026] Preferably, the lip 131 has a structure that gradually narrows from wide to narrow, and the width becomes narrower the further away from the fixed edge 111.

[0027] Specifically, since the lip 131 has a structure that gradually narrows from wide to narrow, the suction part 13 becomes narrower as it gets closer to the fruit and vegetable, so that the lip 131 can better fit fruits and vegetables of different shapes and sizes.

[0028] Preferably, the lip edge 131 is made of a soft material.

[0029] Furthermore, the lip 131, made of a soft material, can adaptively expand or contract when the suction part 13 is sucking up fruits and vegetables of different shapes and sizes, ensuring the deformation compensation capability of the lip.

[0030] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
