Description

Technical Field

[0001] The utility model relates to the technical field of vacuum filling machines, in particular to a clamping mechanism of a vacuum filling machine. Background Art

[0002] With the development of science and technology, vacuum filling machines are widely used in various fields. The existing vacuum filling machines generally include a workbench, a carrier placed on the workbench, and a vacuum filling head located above the workbench. When in use, the operator first places the packaging bag at the processing position, and then fills the packaging bag with materials through the vacuum filling head. After the material filling is completed, the operator removes the packaging bag from the carrier.

[0003] The existing vacuum filling machine chucks generally use friction or raised clamping to clamp the product, which makes the product not only easy to fall off, but also easy to tilt. Even if the clamping force is increased and the spring force is increased, the entire mechanism also needs to be increased, and the chuck strength also needs to be adjusted; the general fixed puncture chuck cannot be applied to multiple models, and the cost of replacing the chuck is very high. Because the spring force is not that strong, the puncture cannot be performed on a large area when using puncture. If the puncture is performed on a large area, the increase in the puncture hole of the product will cause the fixed product to tilt; when the bag mouth is sucked open, the closure of the chuck and the opening of the suction cup are difficult to ensure stability, and the chuck space is large, making it difficult to adjust the avoidance position. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a chuck mechanism for a vacuum filling machine. Through the mounting holes and screws set on the first chuck and the second chuck, for products with different widths, it is only necessary to adjust the position of the punctured screws, which can be applied to a variety of models, and the gap in the middle of the chuck reserves enough space for the suction cup to adsorb and open the aluminum-plastic film. The relative friction of the puncture clamping can use the minimum force to clamp very heavy products, and it has stability and a simple structure; through the chuck cylinder, moving plate, mounting frame, cross bar and slider, when the suction cup adsorbs and opens the product force, the chuck can automatically retract to reduce the actuator, and can also automatically adjust the position, and can quickly return to the initial position after the adsorption is completed; the mechanism is simple to process, low in cost, simple to change, and simple to debug.

[0006] According to the chuck mechanism of the vacuum filling machine, the chuck cylinder is electrically connected to an external power source, and the number of the first chuck and the number of the second chuck are both two and symmetrically distributed.

[0007] According to the chuck mechanism of a vacuum filling machine, the outer surfaces of the first chuck and the second chuck are both provided with mounting holes, the number of the mounting holes is multiple and arranged in a linear array, and screws are threadedly connected to the inside of the mounting holes.
