Abstract
Description
Technical Field
[0001] This invention belongs to the field of vacuum handling technology, specifically relating to a vacuum bag-handling suction cup and handling machine. Background Technology
[0002] Currently, most vacuum handling machines on the market are equipped with round suction cups, and they also use a layer of well-sealed sponge underneath the suction cups for handling. However, these suction cups are only suitable for handling some types of plastic blocks and cardboard boxes. They are difficult to use for handling non-vacuum bagged packaging, and the bags may deform significantly, posing a risk of the transported items falling and causing injury. Summary of the Invention
[0003] The purpose of this invention is to provide a vacuum bag-handling suction cup and a handling machine that can improve the stability of bagged items after adsorption.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a vacuum bag-carrying suction cup, comprising a suction cup body, the suction cup body being elongated elliptical, having a vent hole and a vent pipe for connecting a fan on its top surface, and having an open bottom to form a side wall; a sealing ring with a "U" shaped cross-section is installed at the bottom of the side wall, and a positioning ring for positioning the sealing ring is provided on its outer wall.
[0005] Furthermore, it also includes a ventilation mesh plate, which is installed inside the suction cup body.
[0006] Furthermore, it also includes a mesh plate pad, which is installed between the top of the ventilation mesh plate and the suction cup body.
[0007] Furthermore, the ventilation mesh plate is provided with through holes that communicate with the ventilation pipe.
[0008] Furthermore, it also includes a clamp, which is disposed on the outer surface of the sealing ring to fix it at the bottom opening of the suction cup body.
[0009] Furthermore, the sealing ring has a groove, the width of which is less than the thickness of the bottom sidewall of the suction cup body.
[0010] The present invention also provides a handling machine, including a vacuum bag-handling suction cup, a handle installed on the top of the vacuum bag-handling suction cup, and a fan connected to the vacuum bag-handling suction cup in an air passage, wherein the vacuum bag-handling suction cup is one of the aforementioned vacuum bag-handling suction cups.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1) The present invention uses an elongated elliptical suction cup body, which can increase its contact area with the surface of the bag, thereby improving the stability after adsorption and effectively preventing items from falling off.
[0013] 2) The present invention uses a breathable mesh plate, which can make the negative pressure inside the suction cup body evenly distributed on the one hand, and prevent foreign objects from entering the suction device on the other hand.
[0014] 3) The present invention uses a sealing ring with a "U" shaped cross section, which not only facilitates installation and fixation, but also increases the inner cavity volume of the suction cup body, thereby adapting to the deformation of larger bags. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figures 1 to 7 As shown, a vacuum bag-carrying suction cup includes a suction cup body 1. The suction cup body 1 includes a top plate 1.4 and a side plate 1.5. The top plate 1.4 is an elongated ellipse, that is, the two ends are semi-circular and the middle part is rectangular. The side plate 1.5 is arranged around the edge of the top plate 1.4. The two are fixed by welding and form an inner cavity.
[0024] The top plate 1.4 of the suction cup body 1 is provided with a vent hole 1.3 and a vent pipe 5 for connecting a blower. The top plate 1.4 is also provided with a connection hole 1.2 for mounting a handle. Clearly, the blower is connected to the handle via a pipe, forming an air passage with the vent hole 1.3 and the vent pipe 5. The bottom of the side plate 1.5 is open, and a U-shaped sealing ring 3 is installed at its bottom. A positioning ring 7 for positioning the sealing ring 3 is welded to its outer wall. Clearly, the positioning ring 7 is also elongated elliptical in shape. When the sealing ring 3 is installed at the bottom of the side plate 1.5, its top surface abuts against the bottom surface of the positioning ring 7, thus achieving the purpose of positioning and installation.
[0025] To prevent foreign objects from entering and to ensure a more uniform negative pressure distribution within the suction cup body 1, as a preferred embodiment, the vacuum bag-handling suction cup also includes a ventilation mesh plate 6, which is installed inside the suction cup body 1. The ventilation mesh plate 6 is welded and fixed to the inner cavity of the suction cup body 1. Due to its numerous mesh openings, it effectively prevents foreign objects from entering the blower through the ventilation holes 1.3 and ventilation pipe 5, thus avoiding malfunctions. Simultaneously, it also ensures a more uniform distribution of negative pressure within the inner cavity.
[0026] To facilitate airflow by creating a space between the ventilated mesh panel 6 and the top plate 1.4 after installation, the vacuum bag-moving suction cup also includes a mesh panel pad 4, which is installed between the top of the ventilated mesh panel 6 and the suction cup body 1. Due to the presence of the mesh panel pad 4, the ventilated mesh panel 6 can be directly placed against the mesh panel pad 4 during installation, thus achieving the positioning and installation of the ventilated mesh panel 6. The number of mesh panel pads 4 is determined according to actual needs and will not be elaborated here.
[0027] To ensure that the negative pressure generated by the vent pipe 5 can directly act on the surface of the bag, the vent mesh plate 6 is provided with through holes that communicate with the vent pipe 5. Part of the airflow generated by the negative pressure enters the fan directly through the vent pipe 5 at the through holes, while the remaining airflow enters the fan through the vent mesh plate 6.
[0028] To facilitate the fixing of the sealing ring 3, the vacuum bag-handling suction cup also includes a clamp 2, which is set on the outer surface of the sealing ring 3 to fix it to the bottom opening of the suction cup body 1. The clamp 2 can be tightened by locking screws, thereby pressing the sealing ring 3 against the outer wall of the side plate 1.5.
[0029] To facilitate the pre-fixation of the sealing ring 3 to the bottom of the side plate 1.5, thereby simplifying the subsequent installation of the clamp 2, the sealing ring 3 has a groove 3.1. The width of the groove 3.1 is less than the thickness of the bottom side wall of the suction cup body 1. In this way, the sealing ring 3 will be pre-fixed by the elasticity of the material itself, clamping it to the bottom of the side plate 1.5. Furthermore, because there is a certain distance between the bottom of the groove 3.1 and the bottom of the sealing ring 3, for example, 3mm, the internal space of the suction cup body 1 is larger, allowing the bag to deform more during suction.
[0030] Based on the same inventive concept, the present invention also provides a conveying machine, including a vacuum bag-carrying suction cup, a handle installed on the top of the vacuum bag-carrying suction cup, and a fan connected to the vacuum bag-carrying suction cup in an air passage, wherein the vacuum bag-carrying suction cup is one of the aforementioned vacuum bag-carrying suction cups.
