Description

Technical Field

[0001] The utility model relates to the technical field of suction devices, and more specifically, to a packaging suction device structure. Background Art

[0002] In the existing product manufacturing process, packaging bags, cartons, etc. are needed to package the products. After the packaging bags are made, they are tightly together. Generally, manual operation is required to take the packaging bags, which is time-consuming and labor-intensive, and has low production efficiency.

[0003] The existing Chinese patent announcement number CN215156147U discloses an automatic bag opening device for packaging bags, which includes a supporting structure, a feeding structure and a silo arranged side by side on the supporting structure and used to place packaging bags, a liftable feeding plate and a first driving unit that drives the feeding plate to rise and fall; an upper suction cup structure is fixed on the supporting structure and is used to absorb the packaging bags located in the silo, and it includes a movable plate movably arranged above the silo, an upper suction cup fixing plate liftably arranged on one side of the movable plate, an upper suction cup fixed on the upper suction cup fixing plate and used to absorb the packaging bags, a second driving unit that drives the movable plate to move, and a third driving unit that drives the upper suction cup fixing plate to rise and fall; a lower suction cup structure is fixed on the supporting structure and is used in conjunction with the upper suction cup structure, and it includes a lower suction cup fixing plate fixed above the supporting structure and a lower suction cup fixed on the lower suction cup fixing plate. That is, it can be seen from the accompanying drawings that similar devices have relatively high requirements for the contact surface of the packaging bag when taking the packaging bag, and the effect of taking the packaging bag with an uneven contact surface or liquid packaging bags, cartons, etc. is relatively poor.

[0004] There is also a Chinese patent announcement number CN115352674B that discloses a cigarette box flipping and cover box device, which is provided with a flipping mechanism. When the cigarette box moves to the cigarette packaging position on the conveyor, the cigarette box is also moved and flipped by a flexible suction cup. In addition, a negative pressure area is provided on the flexible suction cup, so that when the flexible suction cup contacts the dehumidifying paper, the dehumidifying paper is adsorbed. Similarly, it can be seen from the attached drawings that when the above-mentioned device takes the packaging paper, the suction area of the suction cup for the packaging paper and the packaging box is very limited, and there are also considerable requirements for its contact surface.

[0005] Therefore, the existing packaging suction device structure is still relatively inadequate for taking out packaging paper, packaging boxes, or liquid packaging bags with irregular contact surfaces. Utility Model Content

[0006] The utility model provides a packaging suction device structure which can have better adsorption force on packaging paper, packaging box or liquid packaging bag with irregular contact surface.

[0007] To solve the above technical problems, the technical solution adopted by the present utility model is as follows:

[0008] Provide a packaging suction tool structure, including a suction tool body with an internal vacuum tube. An air inlet hole and an exhaust hole connected to the vacuum tube are provided on the suction tool body. A flexible suction disc and several suction cup mounting holes communicated with the vacuum tube are provided below the suction tool body. The flexible suction disc is connected to the lower surface of the suction tool body through a multi-layer structure, and the suction cup mounting holes are all arranged within the coverage range of the flexible suction disc.

[0009] As an improvement, the shape of the orthographic projection surface of the flexible suction disc is a hollow ellipse. An opening is provided below the suction tool body within the hollow range of the ellipse. The flexible suction disc is communicated with the vacuum tube through the opening; the suction cup mounting holes are all arranged within the hollow range of the ellipse, and the suction cup mounting holes are arranged on the outer periphery of the opening.

[0010] As an improvement, several ribs are arranged along the circumferential direction on the inner surface of the flexible suction disc, and the ribs are perpendicular to the boundary of the ellipse.

[0011] As an improvement, flexible reinforcing ribs are arranged along the circumferential direction on the inner surface of the flexible suction disc. Several contact ribs are arranged on the flexible reinforcing ribs. The number of the contact ribs is equivalent to that of the ribs, and the contact ribs and the ribs are arranged in an alternating manner; one end of the rib is fixed on the flexible reinforcing rib and the other end is fixed on the inner surface of the flexible suction disc.

[0012] As an improvement, several disc surface reinforcing ribs are arranged along the circumferential direction on the outer surface of the flexible suction disc. The disc surface reinforcing ribs are perpendicular to the boundary of the ellipse, and the several disc surface reinforcing ribs are arranged at equal intervals.

[0013] As an improvement, an annular mounting rail is provided below the suction tool body within the orthographic projection range of the flexible suction disc. The suction cup mounting holes are arranged at equal intervals on the annular mounting rail and are communicated with the vacuum tube.

[0014] Preferably, the multi-layer structure is a flexible double-layer structure.

[0015] Optionally, a detection hole communicable with the vacuum tube is further provided on the suction tool body.

[0016] Compared with the prior art, the packaging suction device structure of the present utility model is provided with a plurality of suction cup mounting holes for installing suction cups, and a flexible adsorption disc is further arranged on the outer periphery of these suction cup mounting holes. When it is necessary to grasp packaging paper, packaging boxes or liquid packaging bags with special-shaped contact surfaces, etc., while the suction cups installed on the suction cup mounting holes are grasping, the flexible adsorption disc can adsorb the outer periphery of the suction cups in a larger area, and because it has a thin and soft lip edge, it can adapt to more irregular or uneven contact areas. The overall sealing performance and grasping ability are stronger, and the demand for vacuum flow is low. It can handle different types of objects and is suitable for dynamic grasping working conditions such as logistics, warehousing, e-commerce and recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment 1

[0021] As Figure 1 、 Figure 2 shown is an embodiment of the packaging suction device structure of the present utility model. As Figure 1As shown in the figure, the packaging suction structure includes a suction body 10 with a built-in vacuum tube (not shown in the figure). An air inlet hole 101 and an air outlet hole 102 connected to the vacuum tube are provided on the suction body 10. Among them, a flexible suction disc 11 and a plurality of suction cup mounting holes 12 communicating with the vacuum tube are provided below the suction body 10. The flexible suction disc 11 is connected to the lower surface of the suction body 10 through a multi-layer structure 111, and the suction cup mounting holes 12 are all arranged within the coverage range of the flexible suction disc 11. That is to say, the flexible suction disc 11 is arranged on the outer periphery of the suction cup mounting holes 12. Then, when suction cups are installed in the suction cup mounting holes 12, the suction cups are all within the overall suction range of the flexible suction disc 11. In addition, since the suction structure of the flexible suction disc 11 for grasping objects is a flexible lip, it can better fit the contact surface of the objects. In actual applications, such as Figure 1 , Figure 2 As shown in the figure, the multi-layer structure 111 can be set as a flexible double-layer structure, which has stronger flexibility and better fits and secures the suction of the contact surfaces of irregular or non-planar objects.

[0022] In the packaging suction structure of this embodiment, a flexible suction disc 11 is also provided on the outer periphery of these suction cup mounting holes 12. When it is necessary to grasp packaging paper, packaging boxes or liquid packaging bags with special-shaped contact surfaces, etc., while the suction cups installed on the suction cup mounting holes 12 are grasping, the flexible suction disc 11 can adsorb the outer periphery of the suction cups over a larger area. And due to its flexible nature, that is, it has a thin and soft lip that can adapt to more irregular or uneven contact areas, so that the overall sealing performance and grasping ability are stronger when grasping objects, and the demand for vacuum flow is low. It can handle different types of objects and is suitable for dynamic grasping working conditions such as logistics, warehousing, e-commerce and recycling.

[0023] Embodiment Two

[0024] As an improvement to Embodiment One, as Figure 1 shown in the figure, the shape of the orthographic projection surface of the flexible suction disc 11 is a hollow ellipse. An opening 13 is provided below the suction body 10 within the hollow range of the ellipse, and the flexible suction disc 11 communicates with the vacuum tube through the opening 13; the suction cup mounting holes 12 are all arranged within the hollow range of the ellipse, and the suction cup mounting holes 12 are arranged on the outer periphery of the opening 13. That is to say, the suction cups arranged in the middle of the flexible suction disc 11 perform point suction on the objects to be grasped, while the flexible suction disc 11 has an elliptical suction surface, so it performs surface suction on the objects to be grasped. Due to its thin and soft lip, it can fit according to the contact area of the objects, with a larger suction area and a more stable grasp of the objects. It can be understood that the suction cup mounting holes 12 below the suction body 10 can be assembled with suction cups of different sizes according to the actual objects to be grasped. The suction cups and the flexible suction disc 11 cooperate with each other to achieve stable grasping of non-planar objects and are also applicable to grasping objects with special-shaped structures.

[0025] Embodiment III

[0026] As an improvement to the above embodiments, in order to increase the adsorption area, as Figure 1 shown, a number of ribs 112 are circumferentially arranged on the inner surface of the flexible adsorption disc 11, and the ribs 112 are arranged perpendicular to the elliptical boundary. That is, these ribs 112 provided on the inner surface of the flexible adsorption disc 11 are basically arranged in a divergent manner centered on the center of the ellipse, with a larger adsorption surface and stronger adsorption ability when grasping an object.

[0027] As a preferred embodiment, as Figure 1 shown, a flexible reinforcing rib 113 is circumferentially arranged on the inner surface of the flexible adsorption disc 11, and a number of contact ribs 114 are arranged on the flexible reinforcing rib 113. The number of the contact ribs 114 is equivalent to that of the ribs 112, and the contact ribs 114 and the ribs 112 are arranged in an alternating manner; one end of the rib 112 is fixed on the flexible reinforcing rib 113 and the other end is fixed on the inner surface of the flexible adsorption disc 11. The staggered arrangement of the lengths of the contact ribs 114 and the ribs 112 can further increase the adsorption area and improve the stability and reliability of grasping an object; in addition, the flexible reinforcing rib 113 can improve the stability of the lip of the flexible adsorption disc 11 and avoid excessive deformation when grasping an object.

[0028] In addition, as Figure 2 shown, a number of disc surface reinforcing ribs 115 are circumferentially arranged on the outer surface of the flexible adsorption disc 11. The disc surface reinforcing ribs 115 are arranged perpendicular to the elliptical boundary, and the number of the disc surface reinforcing ribs 115 is equidistantly arranged. The disc surface reinforcing ribs 115 can further improve the stability of the lip of the flexible adsorption disc 11 and also avoid excessive deformation when grasping a non-planar object.

[0029] In the embodiment of the present utility model, as Figure 1 shown, a circular installation rail 14 is provided below the suction tool main body 10 within the orthographic projection range of the flexible adsorption disc 11, and the suction cup installation holes 12 are equidistantly arranged on the circular installation rail 14 and communicated with the vacuum tube. In practical applications, the number of the suction cup installation holes 12 can be arranged according to needs. In addition, as Figure 2 shown, a detection hole 103 that can be communicated with the vacuum tube is further provided on the suction tool main body 10, which is convenient for observing and detecting the situation inside the vacuum tube and the like.

[0030] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
