Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to an automatic packaging machine with adaptive vertical sealing and buffering function. Background Art

[0002] Patent document CN218617507U discloses a packaging bag sealing mechanism, which includes a shell, a fixed shell, a positioning component, a lifting plate, a sealer and a flattening component. The fixed shell is arranged on the bottom of the shell, the positioning component is arranged in the fixed shell, the lifting plate is slidably arranged in the shell, the sealer is arranged on the lifting plate, and the flattening component is arranged on the lifting plate. The positioning component includes a reciprocating motor, a reciprocating half gear, a reciprocating shell, and a reciprocating rack. It is convenient to position and align the placed packaging bags, avoid bag position deviation, improve the sealing effect, and avoid abnormal sealing. The packaging bag can be flattened by the flattening component to avoid uneven sealing during sealing, which affects the normal sealing of the packaging bag. The cooling fan is convenient for cooling, and the rubber plate is convenient for protecting the packaging bag. However, the sealer of this sealing mechanism is difficult to make real-time micro-adjustments according to the unbalanced pressure distribution at both ends, and the problem of uneven sealing state of the packaging bag mouth is prone to occur. Therefore, it is necessary to optimize its structure to overcome the above defects. Utility Model Content

[0009] A heating and heating component is installed in the top pressure sealing component and is connected to a power source, and the heating and heating component heats the top pressure sealing component;

[0010] A deflection pressure-bearing component is installed in the top pressure sealing component and cooperates with the bearing assembly component. The top pressure sealing component can be deflected in the bearing assembly component by the deflection pressure-bearing component to perform micro-angle adjustment;

[0011] The telescopic buffer component is installed between the top pressure sealing component and the load-bearing assembly component, and the telescopic guide component guides and buffers the telescopic process of the top pressure sealing component.

[0012] Specifically, the load-bearing assembly components include:

[0017] The top pressure bar block is in the shape of a long strip, the rear end of which is placed in the assembly notch, and the front end of which is exposed in front of the assembly notch, and a micro-motion gap is left between the left and right ends and the rear end of the top pressure bar block and the assembly notch.

[0018] The heating components include:

[0019] A heating tube body, which is embedded in the top pressing strip block and extends along the length direction of the top pressing strip block;

[0020] The wiring terminal is installed at the end of the top pressure clause and is electrically connected to the heating tube body through a line. The heating tube body can be connected to the power supply through the wiring terminal.

[0021] The deflection bearing assembly includes:

[0022] A deflection core shaft is installed in the middle of the top pressure strip block and is perpendicular to the top pressure strip block. Its two ends are exposed from the upper and lower ends of the top pressure strip block. A guide notch is opened in the supporting frame. The guide notch extends backward from the opening of the assembly groove and is perpendicular to the deflection core shaft.

[0026] The advantages of the utility model are:

[0027] The sealing mechanism effectively solves the problem of sealing defects caused by unbalanced force at both ends of the mouth of the packaging bag through the deflection pressure-bearing component. When the top pressure strip performs a sealing operation during the extension and retraction process, if the force at both ends of the mouth of the packaging bag is unbalanced, resulting in uneven sealing state, the coordinated design of the deflection core shaft and the guide notch enables the top pressure strip to deflect slightly. This deflection action can compensate for the sealing defects caused by unbalanced force, thereby ensuring the sealing quality of the mouth of the packaging bag, and further enhances the stability and accuracy of the sealing through the telescopic buffer component. The coordinated use of the telescopic end shaft and the buffer spring not only guides the extension and retraction process of the top pressure strip, but also buffers its extension and retraction process, reducing uneven sealing or damage that may be caused by rapid or sudden movement.
