DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 8 As shown, a sealing machine for bagged food comprises a machine body 1, a mounting groove 2 is provided on one side of the long side of the machine body 1, the sealing machine further comprises a drawer body 3 which is horizontally slidably connected to the inner side of the mounting groove 2, a vacuum pump 7 for vacuuming the bag is fixedly installed inside the machine body 1, a quick fixing structure is provided between the rear plate of the drawer body 3 and the mounting groove 2, a liquid storage tank 32 for collecting liquids such as soup is fixedly installed on the drawer body 3, a lifting structure is provided on the bottom plate inside the machine body 1, an upper pressing plate 43 is movably connected inside the machine body 1 through the lifting structure, a sealing structure and a sealing structure are connected between the upper pressing plate 43 and the drawer body 3, the lifting structure controls the distance between the upper pressing plate 43 and the drawer body 3, thereby controlling whether the sealing machine can operate, and a through hole 71 is provided through the upper pressing plate 43. An exhaust pipe 72 is connected between the top of the through hole 71 and the vacuum pump 7, an upper baffle 51 is arranged at the bottom of the upper pressure plate 43, and a capacitive touch sensor chip 52 is detachably arranged on the side of the upper baffle 51 by screws. The capacitive touch sensor chip 52 is of ANY01 model, which can sense capacitance changes through any non-conductive medium, so as to intelligently detect the presence or absence of liquid. The detection end of the capacitive touch sensor chip 52 extends into the liquid storage tank 32, and the installation height of the capacitive touch sensor chip 52 is adjusted to control the maximum liquid level height at which the work is stopped. A controller is also installed inside the body 1, and the capacitive touch sensor chip 52 is electrically connected to the controller. The capacitive touch sensor chip 52 transmits data to the controller, so that the controller can control the working state of the lifting structure.

[0030] In some specific embodiments, such as Figure 6 As shown, in order to facilitate the control of the upper pressure plate 43 to be lifted and lowered, the lifting structure includes a lifting airbag 42, a delivery pipe 41 and an air pump 4. Two lifting airbags 42 are provided. In order to prevent the upper pressure plate 43 from shifting during the lifting process, a vertical telescopic rod (not shown in the figure) is provided inside each lifting airbag 42. The two lifting airbags 42 are arranged between the upper pressure plate 43 and the bottom plate of the body 1. Each lifting airbag 42 is connected to a delivery pipe 41. The air pump 4 is fixedly installed inside the body 1. The end of the delivery pipe 41 away from the lifting airbag 42 is connected to the air pump 4. The air pump 4 is electrically connected to the controller. The controller controls the air pump 4 to inflate and inhale. Inflation and deflation of the two lifting airbags 42 at the same time can drive the upper pressure plate 43 to be lifted and lowered.

[0031] In some specific embodiments, such as Figure 7 As shown, in order to facilitate the formation of a sealed space, the sealing structure includes a pressure ring 44 and a sealing ring 33. The sealing ring 33 is fixedly arranged on the opening circumference of the drawer body 3 corresponding to the liquid storage tank 32. The pressure ring 44 is fixedly arranged on the upper pressure plate 43 at a position aligned with the sealing ring 33. The upper pressure plate 43 drives the pressure ring 44 to descend, so that the pressure ring 44 and the sealing ring 33 form a seal, so that the liquid storage tank 32, the upper pressure plate 43, the sealing ring 33, the pressure ring 44 and the sealing ring 33 form a sealed environment with the packaging bag opening having concave and convex pits, which is convenient for providing working conditions for vacuum extraction.

[0032] In some specific embodiments, such as Figure 8 As shown, in order to facilitate the sealing of the vacuum packaging bag, the sealing structure includes a convex strip 31, which is detachably arranged on the top side of the drawer body 3 near the edge, and a heat sealing component 6 is fixedly installed at the bottom of the upper pressing plate 43 in a position aligned with the convex strip 31. The upper pressing plate 43 drives the heat sealing component 6 to move closer to the heat sealing component 6, and then the heat sealing component 6 heats to seal the packaging bag.

[0033] In some specific embodiments, such as Figure 4 or Figure 5 As shown, in order to facilitate the rapid cleaning of the liquid inside the liquid storage tank 32, the rapid fixing structure includes a limit plate 34, and symmetrical slide rails 22 are fixedly arranged on the left and right side walls of the installation groove 2, respectively. Limit plates 34 slidably connected to the slide rails 22 are fixedly arranged on the left and right sides of the drawer body 3. There are two limit plates 34 on each side, and the two limit plates 34 are respectively arranged on the upper and lower sides of the corresponding slide rails 22 to play a limiting role. The drawer body 3 can drive the liquid storage tank 32 to slide smoothly along the limit plates 34 to avoid shaking during the movement of the drawer body 3, which may cause liquids such as soup to splash out. To increase the difficulty of cleaning, after fixing, the limit plate 34 has a supporting effect on the slide rail 22 to prevent the pressure ring 44 from squeezing the sealing ring 33 and causing the position of the drawer body 3 to shift. A plurality of reinforcement plates 35 are fixedly distributed on the side of each limit plate 34 away from the slide rail 22 to further enhance the supporting force of the limit plate 34. A connecting protrusion 30 is provided on the rear plate of the drawer body 3, and a buckle 21 aligned with the connecting protrusion 30 is provided on the mounting groove 2. The buckle 21 is snapped with the corresponding connecting protrusion 30. After snapping, the drawer body 3 is prevented from moving horizontally, and it is convenient to disassemble and clean the liquid storage tank 32.

[0034] In some specific embodiments, such as Figure 5 As shown, in order to facilitate the alignment of the limit plate 34 and the slide rail 22, the slide groove formed by the insertion ends of the two corresponding limit plates 34 is in an eight-shaped shape, which increases the insertion diameter and facilitates the insertion of the slide rail 22 between the two limit plates 34, thereby enhancing convenience.

[0035] In some specific embodiments, such as Figure 5 or Figure 7 As shown, in order to prevent the packaging bag from being inserted too much, a plurality of lower baffles 36 are distributed inside the liquid storage tank 32. The lower baffles 36 and the upper baffles 51 are arranged crosswise and are located on the same vertical plane. The lower baffles 36 and the upper baffles 51 block the ends of the packaging bags to prevent the packaging bags from being inserted too much, causing the ends of the packaging bags to miss the sealed environment, thereby making it impossible to evacuate the packaging bags.

[0036] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0037] During normal operation, the port of the packaging bag is inserted into the top position of the liquid storage tank 32, and then the upper pressure plate 43 is driven to descend by controlling the lifting structure. First, the air pump 4 draws the air in the lifting airbag 42, and the upper pressure plate 43 drives the pressure ring 44 to approach the sealing ring 33. The pressure ring 44 and the sealing ring 33 close to the side of the convex strip 31 press the port of the packaging bag to achieve sealing, and start the vacuum pump 7. The sealed space is evacuated through the exhaust pipe 72 and the through hole 71, and suction is generated from the top of the upper pressure plate 43 to extract the air inside the packaging bag and the enclosed space to the outside. If there is liquid in the packaging bag, the side liquid will flow into the liquid storage tank 32. After the vacuuming is completed, the heat sealing component 6 heats the bag mouth to seal it.

[0038] When there is too much liquid in the liquid storage tank 32, after the end of the capacitive touch sensor chip 52 detects the liquid, the capacitive touch sensor chip 52 transmits the detected data to the controller, and the controller controls the air pump 4 to start the lifting airbag 42, and the upper pressure plate 43 rises, and a sealed environment cannot be formed, so that the packaging bag cannot be vacuumed, thereby reminding the user to clean the liquid in the liquid storage tank 32 to avoid the liquid in the liquid storage tank 32 overflowing, thereby causing water ingress to the circuit board, causing a short circuit, and causing mold and odor inside the machine and other problems.

[0039] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
