A sealing machine with notch-cutting function is related to provide a frame on the notch- cutting component of the sealing machine. The center of the frame is pivoted with the base via a pivot shaft and has a first end and a second end on the left and right ends. A notch-cutting knife is fixed on the top surface of the first end. A spring having one end is fixed with the frame and the other end is fixed with the base and has a force to push the first end and the notch-cutting knife to move downward. The top wall of the base is configured with a knife dispensing opening at a position corresponding to the notch-cutting knife. The top wall of the base has an opening at a position corresponding to the second end. The bottom surface of the upper cover is protruding downward to form a top rod at a position corresponding to the opening. When the upper cover faces downward to cover the base, the bottom end of the top rod passes through the opening and presses the second end to move downward, thereby the frame taking a pivot shaft as a pivot point to enable the first end and the notch-cutting knife to move upward, and the notch-cutting knife stretches out above the top surface of the base through the knife dispensing opening. Based on the design, when the upper cover of the sealing machine is not closed, the notch-cutting knife is hidden inside the machine body and the operator will not be injured by notch-cutting knife. Therefore, the present invention provides safe use.

Complete technical specification and implementation details from the patent document.
The present invention relates to a sealing machine, and more particularly to a sealing machine with notch-cutting function.
Accordingly, a sealing machine is a device used to pack products, such as food, medicines and cosmetics, etc. The sealing machines could be two types, wherein one is the general type sealing machine used to seal packing bags (e.g., plastic bags) and the other one is vacuum sealing machine used to suck out the air inside the packing bag or container of products to form a vacuum environment, thereby using a heat sealing technique to seal the packing bag or container to extend the shelf life of the products and avoid oxidation and bacteria. The vacuum sealing machine is widely used in food industry, pharmaceutical industry and cosmetics industry to effectively protect the quality and safety of products and extend the shelf life and are popular and widely applied by consumers.
In order to tear the sealed packing bag conveniently, some conventional sealing machines will cut out a notch at the bag mouth beyond the packing range of the packing bag after sealing, thereby tearing the bag mouth of the packing bag to take out the products conveniently. However, in the conventional sealing machine with notch-cutting function, the notch-cutting knife used to cut the notch is exposed and during the sealing operation, the exposed notch-cutting knife may easily hurt the user by accident. In view of the above shortcoming in the application of the conventional sealing machine with notch-cutting function, the inventor of the present invention endeavored to improve the design and produced the present invention.
It is a primary objective of the present invention to provide a notch-cutting knife to cut a notch on the packing bag, wherein the notch-cutting knife is hidden inside the machine body when the upper cover of the sealing machine is not in the cover closed status, so as to provide a sealing machine with notch-cutting function which can be operated more safely.
The primary feature of the present invention is related to the notch-cutting component being configured with a frame inside the base of the sealing machine. The center of the frame is pivoted with the base via a pivotal shaft and the left and right ends have a first end and a second end, a notch-cutting knife is fixed on the top surface of the first end of the frame, a spring with one end fixed with the frame and the other end is fixed with the base, and the spring has a force to push the first end of the frame configured with the notch-cutting knife to move downward. The top wall of the base is configured with a knife dispensing opening at the position corresponding to the notch-cutting knife. The top wall of the base corresponding to the second end of the frame has an opening. The bottom surface of the upper cover of the sealing machine located above the base and at the position corresponding to the opening is protruding downward to form a top rod. When the upper cover is facing downward to close the base, the bottom end of the top rod passes through the opening and presses the second end of the frame to move downward, so that the frame is turned around the pivot shaft and the notch-cutting knife on the first end is lifted to extend out of the top surface of the base via the knife dispensing opening. Thus, at the same time when the upper cover is pressed down to close the base and seal the packing bag, the notch-cutting knife will move up and cut out a notch on the edge of the packing bag beyond the packing range. Based on the above configuration, when the upper cover of the sealing machine is not pressed down, the notch-cutting knife is hidden inside the machine body. Thus, the sealing machine can be operated more safely.
For better understanding of the technical means to accomplish the above object and the effect of the present invention, detailed descriptions are provided below with respect to the following embodiment.
With reference to, the sealing machineis a vacuum sealing machine for example, comprises:
After sequential assembly of the above components, the applications are as following:
According to the above descriptions, in the notch-cutting componentof the present invention, before the upper covercloses the base, the notch-cutting knifeis hidden inside the base. In this way, when pulling the packing bagor placing the packing bagon the basefor vacuum pumping and sealing, the hand of the user will not be hurt by the notch-cutting knifeand the machine can be operated safely.
