[0029] See Figures 1 to 10 This embodiment provides a vacuum sealing machine, including a base assembly 1 and an upper cover assembly 2. The base assembly 1 has a lower sealing cavity 101 on its inner side, and the upper cover assembly 2 has an upper sealing cavity 201 on its inner side. When the inner side of the upper cover assembly 2 is closed with the inner side of the base assembly 1, the upper sealing cavity 201 and the lower sealing cavity 101 form a vacuum cavity. The vacuum cavity is connected to a vacuum pumping mechanism 3 so that the vacuum cavity can be evacuated by the vacuum pumping mechanism 3. A support platform 4 is provided on one side of the lower sealing cavity 101, and a heating mechanism 5 is provided on one side of the upper sealing cavity 201. The heating mechanism 5 and the support platform 4 can form a heat-sealing fit. The two ends of the base assembly 1 are respectively provided with rotating grooves 102, and the ports of the rotating grooves 102 are provided with limiting blocks 103. The middle of the limiting blocks 103 is provided with an inlet / outlet channel 104. The two ends of the upper cover assembly 2 are respectively provided with rotating blocks 202. The rotating blocks 202 at both ends enter the rotating grooves 102 at both ends through the inlet / outlet channels 104, and the rotating blocks 202 and the rotating grooves 102 rotate in fit. Functions: (1) The base assembly has a lower sealing cavity on its inner side and the upper cover assembly has an upper sealing cavity on its inner side. When the inner side of the upper cover assembly and the inner side of the base assembly are closed, the upper sealing cavity and the lower sealing cavity form a vacuum cavity. The vacuum cavity is connected to the vacuum pumping mechanism so that the vacuum cavity can be evacuated by the vacuum pumping mechanism. Thus, the opening of the vacuum bag can be inserted into the vacuum cavity for vacuuming. (2) A support platform is provided on one side of the lower sealing cavity and a heating mechanism is provided on one side of the upper sealing cavity. The heating mechanism and the support platform can form a heat-sealing fit. Thus, when the vacuum bag needs to be heat-sealed, the inner side of the upper cover assembly and the inner side of the base assembly can be closed, and the heat-sealing fit between the heating mechanism and the support platform can be used to heat-seal the opening of the vacuum bag. (3) The base assembly has rotating grooves at both ends, with limiting blocks at the ends of the rotating grooves and inlet / outlet channels in the middle of the limiting blocks. The top cover assembly has rotating blocks at both ends, which enter the rotating grooves through the inlet / outlet channels, allowing for rotational engagement between the rotating blocks and the rotating grooves. When the base assembly and top cover assembly need to be quickly disassembled, the rotating blocks can be pulled outwards through the inlet / outlet channels. When the base assembly and top cover assembly need to be quickly installed, the rotating blocks can be pushed inwards into the rotating grooves through the inlet / outlet channels. Due to the limiting blocks, the rotating blocks can only be pulled outwards again at a specific angle. Therefore, the rotating blocks and rotating grooves can achieve stable rotational engagement, facilitating the adjustment of the top cover assembly angle. From this analysis, it can be seen that this utility model, through the setting of rotating blocks, rotating grooves, and limiting blocks, allows for quick disassembly and installation of the base assembly and top cover assembly of the vacuum sealing machine, making it convenient to use.

[0030] Specifically, a limiting block 103 is disposed at the top of the rotating groove 102.

The arc-shaped surfaces 203 and the U-shaped opening 105 are in rotational engagement. Function: The arrangement of the arc-shaped surfaces 203 and the U-shaped opening 105 allows for a good rotational engagement.

[0031] Specifically, the rotating block 202 has flat surfaces 204 on its other two sides. The width of the flat surfaces 204 is greater than the width of the arc-shaped surfaces 203. The inlet / outlet channel 104 is rectangular, and the flat surfaces 204 can cooperate with the inlet / outlet channel 104. When the inner side of the upper cover assembly 2 is closed with the inner side of the base assembly 1, the arc-shaped surfaces 203 on both sides are located on the front and rear sides of the rotating block 202, respectively, and the flat surfaces 204 on both sides are located on the upper and lower sides of the rotating block 202, respectively. Function: This way, the rotating block 202 can only be pulled out or pushed in through the sliding cooperation between the inlet / outlet channel 104 and the flat surfaces 204 when the upper cover assembly is upright. When the upper cover assembly is flat, the rotating block 202 cannot be pulled out or pushed in due to the limiting cooperation between the inlet / outlet channel 104 and the flat surfaces 204.

[0032] Specifically, the rotating grooves 102 at both ends are respectively located at the left and right ends of the rear edge of the base assembly 1, the U-shaped openings 105 of the rotating grooves 102 at both ends face each other, and the openings 106 of the inlet and outlet channels 104 at both ends face each other; the rear edge of the upper cover assembly 2 is provided with a downwardly protruding connecting block 205, and the rotating blocks 202 at both ends are respectively located at the left and right ends of the connecting block 205; a stop block 107 is provided on the lower front side of the rotating groove 102, and the stop block 107 can cooperate with the rotating block 202. Function: Through the limiting cooperation between the stop block 107 and the rotating block 202, the stop block 107 can provide a certain support force when the upper cover assembly is upright, making the upper cover assembly more stable. Preferably, the bottom of the rotating groove 102 is provided with a drainage hole, and the lower sealing cavity is provided with a removable water receiving groove. Of course, it can also be omitted, depending on the needs.

[0033] Specifically, the support platform 4 is located on the front edge of the base assembly 1, and the lower sealing cavity 101 is located in the middle of the base assembly 1; the heating mechanism 5 is located on the front edge of the upper cover assembly 2, and the upper sealing cavity 201 is located in the middle of the upper cover assembly 2; the left and right ends of the front edge of the base assembly 1 are respectively provided with latches 108, and the left and right ends of the front edge of the upper cover assembly 2 are respectively provided with latches 206 that can move left and right. The latches 206 are connected to the return spring 207, and the latches 206 and the latches 108 can form a locking engagement. Function: When the base assembly 1 and the upper cover assembly 2 are closed, the latches 206 form a locking engagement with the latches 108 under the action of the return spring 207, so that the heat sealing of the vacuum bag is stable. When the latches 206 are pushed manually, the return spring 207 is compressed, and the latches 206 are disengaged from the latches 108, thereby realizing the opening of the base assembly 1 and the upper cover assembly 2.

[0034] Specifically, two positioning blocks 109 distributed along the left and right sides are provided between the lower sealing cavity 101 and the support platform 4, and two positioning holes 208 distributed along the left and right sides are provided between the upper sealing cavity 201 and the heating mechanism 5. The two positioning blocks 109 are respectively positioned and engaged with the two positioning holes 208. Function: By positioning and engaging the two positioning blocks 109 with the two positioning holes 208, the base assembly 1 and the upper cover assembly 2 can be precisely matched.

[0035] Specifically, a protrusion 1010 is provided on one side of the lower sealing cavity 101, and a through hole 209 is provided on one side of the upper sealing cavity 201. A micro switch 6 and a control board 7 are provided inside the upper cover assembly 2. The micro switch 6 is electrically connected to the control board 7. The protrusion 1010 can extend into the through hole 209 to trigger the micro switch 6. Function: When the base assembly 1 and the upper cover assembly 2 are closed, the protrusion 1010 extends into the through hole 209 to trigger the micro switch 6. At this time, the control board 7 knows that the entire machine is in a closed state and then controls the power supply. When the base assembly 1 and the upper cover assembly 2 are opened, the protrusion 1010 leaves the through hole 209. At this time, the control board 7 knows that the entire machine is in an open state and then controls the power supply to be cut off.

[0036] Specifically, the top of the upper cover assembly 2 is equipped with a display screen 8, which is electrically connected to the control board 7; the vacuum mechanism 3 is located inside the upper cover assembly 2, and the vacuum mechanism 3 is a vacuum pump, which is electrically connected to the control board 7. Functions: The display screen 8 can display the working status during sealing and a countdown function; while the vacuum pump can be connected to multiple air extraction holes in the upper sealing cavity 201 for convenient vacuuming.

[0037] Specifically, the heating mechanism 5 includes a nickel-chromium heating wire and high-temperature adhesive tape, the support platform 4 is made of silicone, and sealing rings 9 are provided on the edges of the lower sealing cavity 101 and the upper sealing cavity 201. The width of the nickel-chromium heating wire is 7mm±1mm.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
