[0002] In daily life, if you need to seal a plastic bag, you can only use a clip or a rubber band to tighten it. The seal is not tight enough, and the contents in the bag may still be exposed to the outside world. If you need to open a sealed plastic bag, you need to use scissors or tear it open violently, which may cause safety hazards or irregular openings, and is inconvenient for consumers. In recent years, handheld sealing machine products have appeared on the market. Currently, there are the following types of handheld sealing machines on the market: the first type has only sealing function but no cutting function or only cutting but no sealing function, which has a single function and cannot meet the needs of users; the second type has both sealing and cutting functions. For example, patent No. CN201621096795.1 discloses a handheld double heating sealing machine, but its electric sealing module and cutting tool are arranged on the same side of the sealing machine, and are pressed by the same pressure contact. When pressing, the sealing block used for sealing and the tool used for cutting are pressed down at the same time.

[0031] A guide groove 5.2 is provided on the inner wall of the pressing channel of the button guide bracket 5, a bracket avoidance groove 5.3 is also provided on the pressing channel of the button guide bracket 5, and a protruding bracket stopper 5.4 is provided on the outer wall of the pressing channel of the button guide bracket 5. The bracket stopper 5.4 is mainly used for positioning during installation and use. The button guide bracket 5 is installed in the upper cover 1, and the battery 9 is placed between the lower cover 2 and the lower cover 2, which is used to place the battery 9 that provides power for the sealing heating wire 10. A battery 9 baffle can be provided on the lower cover 2 to facilitate the installation of the battery 9.

[0032] The sealing button assembly 6 comprises a sealing button body 6.1, a sealing pressing step 6.2 is connected to one side of the bottom end of the sealing button body 6.1, a sealing pressing block 6.3 is connected to the bottom of the sealing pressing step 6.2, a sealing button guide column 6.4 is arranged in the middle of the bottom end of the sealing button body 6.1, a sealing button slider 6.5 adapted to the guide groove 5.2 is arranged on the side wall of the sealing button body 6.1, and the sealing pressing step 6.2 is located in the bracket avoidance groove 5.3. By setting a sliding connection structure between the sealing button slider 6.5 and the guide groove 5.2, a sliding contact point is added when the button body 6.1 moves up and down on the basis of the sliding pair composed of the sealing button guide column 6.4 and the sealing guide hole 3.2, so that the sealing button assembly 6 runs more smoothly.

[0033] The sealing jaws component 3 includes a sealing jaws 3.1, a sealing guide hole 3.2 is arranged above the sealing jaws 3.1, the sealing button guide column 6.4 is inserted into the sealing guide hole 3.2, and a sealing spring 3.3 is sleeved on the outer wall of the sealing guide hole 3.2. The top end of the sealing spring 3.3 presses against the inner surface of the sealing button body 6.1, and the bottom end of the sealing spring 3.3 presses against the upper surface of the sealing jaws 3.1.

[0034] The bottom end of the sealing button guide column 6.4 is connected to a sealing button pressing rod 6.6, and a switch 8 adapted to the sealing button pressing rod 6.6 is arranged at the bottom of the sealing button pressing rod 6.6, and the switch 8 is electrically connected to a battery 9 and a sealing heating wire 10.

The sealing heating wire 10 is installed below the sealing jaws 3.1, and the sealing heating wire 10 is arranged opposite to the sealing pressing block 6.3.

[0035] That is, a sealing button assembly 6 is provided at the end of the sealing jaws component 3. When the plastic bag needs to be sealed, the edge of the plastic bag to be sealed is placed into the sealing jaws 3.1, and the sealing button body 6.1 is pressed. The sealing button guide column 6.4 overcomes the elastic force of the sealing spring 3.3 and moves downward along the sealing guide hole 3.2. The sealing button slider 6.5 moves downward along the guide groove, and the sealing pressing block 6.3 moves downward. The sealing button pressing rod 6.6 at the lower end of the sealing button guide column 6.4 contacts the switch 8, and the switch 8 is turned on. The battery 9 The sealing heating wire 10 is powered, and the sealing heating wire 10 heats and melts the plastic bag to seal it. The sealing pressing block 6.3 and the sealing heating wire 10 both have a certain length. If the plastic bag needs to be sealed at a shorter position, the sealing position can be directly placed between the sealing pressing block 6.3 and the sealing heating wire 10, and the sealing button body 6.1 can be pressed to seal it; if the plastic bag needs to be sealed at a longer position, after pressing the sealing button body 6.1, the plastic bag sealing position needs to be moved between the sealing pressing block 6.3 and the sealing heating wire 10. After the sealing is completed, the sealing button body 6.1 is released, and under the restoring force of the sealing spring 3.3, the sealing button body 6.1 is reset upward until the sealing button slider 6.5 moves to the top limit of the guide groove, at which time the sealing button pressing rod 6.6 is out of contact with the switch 8, and the sealing heating wire 10 is powered off and does not heat up.

[0036] The cutting button assembly 7 comprises a cutting button body 7.1, a knife platform 7.2 is connected to one side of the bottom end of the cutting button body 7.1, a blade 7.3 is arranged below the knife platform 7.2, a cutting button guide column 7.4 is arranged in the middle of the bottom end of the cutting button body 7.1, a cutting button slider 7.5 adapted to the guide groove is arranged on the side wall of the cutting button body 7.1, and the knife platform 7.2 is located in the bracket avoidance groove 5.3.

[0037] The cutting jaws component 4 includes a cutting jaws 4.1, a cutting guide hole 4.2 is arranged above the cutting jaws 4.1, the cutting button guide column 7.4 is inserted into the cutting guide hole 4.2, and a cutting spring is sleeved on the outer wall of the cutting guide hole 4.2. The top end of the cutting spring presses against the inner surface of the cutting button body 7.1, and the bottom end of the cutting spring presses against the upper surface of the cutting jaws 4.1.

[0038] When it is necessary to cut the packaging belt, the edge of the packaging bag to be cut is placed in the cutting jaws, and the cutting button body 7.1 is pressed. The cutting button guide column 7.4 overcomes the elastic force of the cutting spring and moves downward along the cutting guide hole 4.2. The cutting button slider 7.5 moves downward along the guide groove, and the blade 7.3 cuts the packaging bag. When the cutting is completed, the cutting button body 7.1 is reset under the restoring force of the cutting spring, and the blade 7.3 moves upward.

[0039] The present invention adds a cutting function to the sealing machine, and the sealing component and the cutting component are separately arranged at the two ends of the sealing machine, so that the sealing operation and the cutting operation do not affect each other, and the situation that when the cutting blade 7.3 is damaged, the sealing problem also occurs, and the misoperation between sealing and cutting is avoided. The operation is convenient, safe and reliable; the sealing button assembly 6 and the cutting button assembly 7 are separately arranged at the two ends of the sealing machine, so that the force of the whole machine is more balanced, and the operation is smoother when the button is pressed; the sealing heating wire 10 at the sealing end is energized and heated by pressing the sealing button body 6.1.
