Description

Bag opening vacuum chuck for arc surface of prefabricated bag

Technical Field

The utility model relates to a bag vacuum chuck is opened to prefabricated bag arc surface.

Background

At present, most of prefabricated bags are manually opened, the working efficiency is low, and when the bags are opened by adopting a sucker, the bag opening of the bag opening mechanism is pulled to be in an approximately elliptical irregular shape, so that the filling is influenced to a certain extent, the filled materials are difficult to enter the bags, or the prefabricated bags which are much larger than the filled materials are required to be filled, so that the packaging cost is increased, and the waste of resources is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prior art not enough and provide a simple structure, can use with filling material assorted size's prefabricated bag, reduced the packaging cost, reduced wasting of resources's prefabricated bag arc surface and opened a bag vacuum chuck.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prefabricated bag arc surface bag opening vacuum chuck, sets up and opposite movement's upside sucking disc and downside sucking disc including the symmetry, the opposite face of upside sucking disc and downside sucking disc is the sucking disc working face, the sucking disc working face for with prefabricated bag pull open back radian assorted circular arc concave surface, the gas pocket that the evacuation was used is covered with in the sucking disc working face. The device ingeniously utilizes the sucker working surface with the arc concave surface to pull the mouth of the prefabricated bag into a circle, so that the maximum filling area is achieved.

Further, the space that its relative sucking disc working face encloses forms the round platform body that the front end is big, the rear end is little after upside sucking disc and the downside sucking disc contact, the front end of round platform body is for advancing the bag end, and the relative working face of sucking disc unit and lower sucking disc unit is not a cylinder on this device, but a round platform shape, and the big end of round platform shape is for advancing the bag end to satisfy the shape that prefabricated bag struts, guarantee that the prefabricated bag sack pulls open to the at utmost.

Furthermore, the distribution density of the air holes of the circular truncated cone body close to the front end of the sucker is greater than that of the air holes at the rear end of the sucker.

Furthermore, the upper side sucker and the lower side sucker are driven to move oppositely through the upper bag opening cylinder and the lower bag opening cylinder respectively.

Furthermore, the sucker working surface is arranged in the middle of the opposite surface of the upper sucker and the lower sucker.

To sum up, the utility model discloses an automatic bag of opening, the sack can be opened to the biggest when having guaranteed that the bag is opened to the prefabricated bag to guarantee can use with filling material phase-match size's prefabricated bag, reduced the packaging cost, reduced the wasting of resources.

In the drawing, 4-13 parts of prefabricated bag, 4-111 parts of upper side sucker, 4-121 parts of lower side sucker, 4-1111 parts of sucker working surface, 4-1112 parts of sucker rear end, 4-1113 parts of sucker front end, 4-1114 parts of air hole.

Detailed Description

For a better understanding of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and the embodiments, however, the present invention is not limited thereto, and the protection scope of the present invention also relates to the equivalent technical means that can be conceived by those skilled in the art according to the inventive concept.

As shown in figures 1 to 4, a prefabricated bag arc surface bag opening vacuum chuck comprises an upper side chuck 4-111 and a lower side chuck 4-121 which are symmetrically arranged and move oppositely, the upper side chuck 4-111 and the lower side chuck 4-121 are driven by an upper bag opening cylinder and a lower bag opening cylinder respectively to move oppositely, the opposite surfaces of the upper side chuck 4-111 and the lower side chuck 4-121 are chuck working surfaces 4-1111, the chuck working surfaces 4-1111 are arc concave surfaces matched with the radian after the prefabricated bag is pulled open, air holes 4-1114 for vacuum pumping are fully distributed in the chuck working surfaces 4-1111, and a space surrounded by the opposite chuck working surfaces 4-1111 after the upper side chuck 4-111 and the lower side chuck 4-121 are contacted forms a circular table body with a large chuck front end 4-1113 and a small chuck rear end 4-1112, the front end of the cone is a bag inlet end, the air hole arrangement density of the cone close to the front end of the sucker is greater than the air hole arrangement density of the rear end of the sucker, and the sucker working face 4-1111 is arranged in the middle of the opposite face of the upper sucker 4-111 and the lower sucker 4-121.

When the bag filling machine works, the upper bag opening cylinder and the lower bag opening cylinder act simultaneously to drive the upper side sucker 4-111 and the lower side sucker 4-121 to move oppositely, so that the upper side sucker 4-111 and the lower side sucker 4-121 are both in contact with the prefabricated bag 4-13 to press the prefabricated bag 4-13 tightly, the upper side sucker 4-111 and the lower side sucker 4-121 begin to vacuumize, the upper side sucker 4-111 and the lower side sucker 4-121 adsorb the upper surface and the lower surface of the mouth of the prefabricated bag, then the upper bag opening cylinder and the lower bag opening cylinder retract to drive the upper side sucker 4-111 to move upwards, the lower side sucker 4-121 moves downwards until the mouth of the prefabricated bag is completely opened, then the filling device acts to push materials into the opened prefabricated bag, and filling is completed.

In addition, it should be noted that the present invention is not limited to the above embodiments, as long as the specific size or shape of the component is not specified, the component can be any size or shape corresponding to the structure, and no matter there is any change in the material composition, all the structural designs provided by the present invention are a variation of the present invention, which should be considered within the protection scope of the present invention.
