Benefits of technology
The present invention aims to provide an improved sealing structure of an air-pocket bag machine that provides an effect of stably heating and sealing an opening in a high-speed packaging operation. The invention includes a driving roller and a heated sealing roller rotatably mounted in a coaxial manner to improve overall heating result and thus increase sealing speed. The heating plate, sealing roller, and driving roller are synchronously performing their respective functions of heating, advancing, and stabilizing the air-pocket bag to achieve a consistent and efficient sealing effect even during high-speed operations.
Problems solved by technology
With such an arrangement, the problems of the prior art sealing device of an air-pocket bag that heating is not uniform, positional shift between an air-pocket bag and a contact surface of a heating element may readily occur, and sealing of an opening may not be done in a complete manner can be overcome.

Embodiment Construction
[0021]The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
[0022]Referring to FIGS. 1, 2, and 3, which are respectively a perspective view and an exploded view of a preferred embodiment of the present invention and a cross-sectional view taken along line A-A of FIG. 1, these drawings clearly show that the present invention comprises:
[0023]at least one heating plate 1;
[0024]a sealing roller 2 that is rotatably mounted to and positioned against the heating plate 1 to apply heating and pressing to and thus sealing at least one air-pocket bag through a heating ...

Abstract
A sealing structure of an air-pocket bag machine includes at least one heating plate, a sealing roller that is rotatably mounted to and positioned against the heating plate for conducting a heating and pressing operation on and thus sealing at least one air-pocket bag through a heating operation of the heating plate, and at least one driving roller that is coaxially and rotatably coupled to the sealing roller for driving and advancing the air-pocket bag. With such an arrangement, when the air-pocket bag machine is activated, the air-pocket bag is driven by being in contact engagement with the driving roller and thus is moved to fast, stably, and continuously pass under the sealing roller. Due to the sealing roller and the driving roller being rotatably coupled in a coaxial manner, the advancing speed of the air-pocket bag is consistent with the rotational speed of the sealing roller.
Description
TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates generally to an improved sealing structure of an air-pocket bag machine, and more particularly to an improved sealing structure of an air-pocket bag machine that provides a uniform heating effect and allows a sealing operation to be performed at an increased speed.DESCRIPTION OF THE PRIOR ART[0002]An article, after being packaged with a package bag, shows advantages of being neat and clean and free of contamination and has a good outside appearance for sale and thus, the sale price can be increased. Further, to protect articles from damages caused by compression and impact, the articles are often packed with air-bubble wraps, or cushioning materials, such as air-bubble sheets, Styrofoam, slit pieces of paper, and balls of used paper, are stuffed between the articles and a package box. Among these materials, an air-pocket bag is structured by filling air into a package bag before an opening is sealed; and then, the o...
