[0028] Reference Figure 1-3 As shown, a vertical vacuum sealing machine includes:

[0029] The vacuum sealing machine body is housed inside the outer casing 1 and is compatible with it. A bag groove 11 is provided at the upper end of the vacuum sealing machine body. From the first end to the second end of the bag groove 11, a sensing unit 2, a vacuum sealing unit 3, and a pressing unit 4 are sequentially arranged. The sensing unit 2 is used to sense the position of the vacuum bag when it enters the first end. The vacuum sealing unit 3 is used to heat and seal the opening of the vacuum bag, perform vacuuming, and transfer the bag to the pressing unit 4. The pressing unit 4 is used to press the sealed area of ​​the vacuum bag. The vacuum sealing machine body also has a controller. The input end of the controller is electrically connected to the sensing unit 2, and the output end of the controller is electrically connected to the vacuum sealing unit 3 and the pressing unit 4. By setting the vacuum sealing machine vertically, the user only needs to insert the vacuum bag into the bag groove, and the equipment can automatically complete the vacuuming, heating and sealing operations, simplifying the operation process and improving efficiency.

[0030] Furthermore, referring to Figure 6-7As shown, to avoid the heating strip 331 failing to accurately seal the vacuum bag due to inaccurate placement of the vacuum bag, thus causing heating and sealing failure, a sensing unit 2 is provided. The interior of the outer shell 1 forms a chamber, and a bag groove 11 is provided at the upper end of the outer shell 1. The bag groove 11 is used for sealing the vacuum bag inside. The sensing unit 2, vacuum sealing unit 3, and pressing unit 4 are arranged sequentially from the first end to the second end of the bag groove 11 in the chamber. The sensing unit 2 includes a first bracket 21 and a micro switch 22. The first bracket 21 is fixedly connected to the outer shell 1. An insertion groove 211 is formed on the first bracket 21. The insertion groove 211 is used for placing the vacuum bag. Micro switches 22 are staggered on both sides of the insertion groove 211.

[0031] In this embodiment, micro switches 22 are respectively disposed at the upper end and the lower end of the first bracket 21, with the upper micro switch 22 positioned corresponding to the heating strip 331 and the lower micro switch 22 positioned closer to the outer casing 1. The micro switches 22 are electrically connected to the controller. When the lower micro switch 22 senses the vacuum bag but the upper micro switch 22 does not sense the vacuum bag, the vacuum sealing machine cannot start the vacuum sealing program. When both the lower and upper micro switches 22 sense the vacuum bag, the vacuum sealing machine starts the vacuum sealing program.

[0032] Furthermore, referring to Figure 4-5 As shown in Figures 8-9, a vacuum sealing unit 3 is provided to achieve vacuum sealing of the vacuum bag. The vacuum sealing unit 3 is provided with a second support 31, which is fixedly connected to the outer shell 1. An upper chamber is formed at the upper end of the second support 31, and a pressure roller 32 is provided in the upper chamber. The pressure roller 32 is sleeved on the rotating shaft, which is connected to a first motor 5. When the vacuum sealing machine executes the vacuum sealing program, the first motor 5 starts and drives the rotating shaft to rotate. The rotating shaft drives the pressure roller 32 to rotate. The pressure roller 32 is used to transfer the vacuum bag part that has been heated and sealed by the heating strip 331 to the pressing unit 4 and perform the first pressing on the sealed area of ​​the vacuum bag to improve the sealing performance of the vacuum bag.

[0033] The second support 31 is provided with a sealing component 35, which includes a first sealing ring 351 and a second sealing ring 352. The first sealing ring 351 is provided on the upper chamber, and the second sealing ring 352 is provided on the lifting support 34. When the vacuum bag is evacuated, the lower chamber and the upper chamber are closed to form a vacuum chamber. The first sealing ring 351 and the second sealing ring 352 are used to improve the airtightness of the vacuum chamber and ensure the sealing of the vacuum bag.

[0034] The lower end of the second support 31 forms a lower chamber, and a sealed space is formed between the upper chamber and the lower chamber. A lifting support 34 is installed in the lower chamber, and a sealing component 33 is installed inside the lifting support 34. A lifting rod 38 is installed on the side of the lifting support 34 away from the pressure roller 32. The lifting rod 38 is connected to a second motor 6. When a vacuuming operation is performed, the second motor 6 is started and the lifting rod 38 is raised. The lifting rod 38 drives the lifting support 34 to rise, so that the lifting support 34 and the upper chamber are closed to form a vacuum chamber. A support rod 37 is connected to the sealing component 33 on the side away from the pressure roller 32. The sealing component 33 is located near the pressure roller 32. A heating strip 331 and an air extraction port 332 are provided on one side of the wheel 32. A connecting pipe 334 connected to the air extraction port 332 is provided on the side of the sealing assembly 33 away from the heating strip 331. The connecting pipe 334 is connected to a vacuum pump through an air pipe. A guide surface 333 is formed on the side of the sealing assembly 33 near the insertion groove 211. The guide surface 333 is used to guide the vacuum bag from the insertion groove 211 into the heating strip 331. If liquid is extracted from the vacuum bag during the air extraction process, it can flow into the lifting bracket 34 along the guide surface 333. The lifting bracket 34 has a drain port and a drain pipe 36 is provided at the drain port.

[0035] Furthermore, referring to Figure 10 As shown, in order to further improve the sealing performance of the vacuum bag, a pressing unit 4 is provided. The pressing unit 4 is provided with a third support 41, and the third support 41 forms an ejection groove 411. Rollers 42 are passed through the upper and lower ends of the third support 41. Rollers 43 are provided on the rollers 42. The rollers 42 are connected to the first motor 5. When the first motor 5 is started, the upper roller 42 and the lower roller 42 rotate in opposite directions. When the heated and sealed area on the vacuum bag passes by, the rollers 43 will perform secondary pressing on the sealed area, expand the molten area, improve the sealing performance of the vacuum bag, and gradually convey the vacuum bag out of the vacuum sealing machine through the rollers 43.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
