[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figures 1-4 , the present application provides a technical solution: a vacuum - pumping and bag - sealing machine, including a chassis main body 1, the top of the chassis main body 1 is hinged with a box cover 2 through a hinge, a micro - controller 3 is fixedly installed inside the chassis main body 1, hot - press sealing mechanisms 4 for sealing are fixedly installed on the inner sides of both the chassis main body 1 and the box cover 2, a vacuum - pumping assembly 500 for pumping vacuum is installed inside the chassis main body 1, and a closing assembly 600 for facilitating opening and closing is installed inside the chassis main body 1; two connection grooves 601 are opened on the front surface of the chassis main body 1, and two docking grooves 602 are opened on the front surface of the chassis main body 1;

[0031] By the combined use of the hot pressing and sealing mechanism 4, the vacuum pumping assembly 500, and the closing assembly 600 inside the chassis main body 1, the vacuum bag sealer can be opened or closed more conveniently and smoothly without the need to force it open, thus avoiding the risk of burns caused by touching the heat source. At the same time, it facilitates the operator's sealing operation and can connect the vacuum space to the outside after sealing, further reducing the difficulty of opening, thereby effectively improving the practical performance of the vacuum bag sealer.

[0032] It should be noted that the front of the top hot pressing and sealing mechanism 4 can be attached to the front of the bottom hot pressing and sealing mechanism 4. The two hot pressing and sealing mechanisms 4 can seal the packaging bag. The hot pressing and sealing mechanism 4 is a device that heats the target object through two heat sources to melt and bond them together to achieve the sealing effect, which is a publicly available technology and will not be elaborated here.

[0033] In this embodiment, the closing assembly 600 is a structure for conveniently and smoothly closing or opening the bag sealer.

[0034] As Figure 1 、 Figure 2 and Figure 3 shown, the closing assembly 600 includes two fixed rods 603 fixedly connected to the front of the box cover 2, trapezoidal clamping blocks 604 fixedly connected to the ends of the fixed rods 603, a sliding plate 605 slidably connected to the inside of the connection groove 601, positioning rods 606 fixedly connected to the inside of the connection groove 601 and evenly distributed, a return spring 607 fixedly connected to the inside of the connection groove 601, two trapezoidal limit blocks 608 respectively fixedly connected to the opposite sides of the two sliding plates 605, two pressing rods 609 respectively fixedly connected to the opposite sides of the two sliding plates 605, and two pressing plates 610 respectively fixedly connected to the opposite ends of the two pressing rods 609.

[0035] It should be noted that the two trapezoidal clamping blocks 604 are symmetrically distributed left and right. One end of the positioning rod 606 penetrates the left side of the corresponding sliding plate 605. The opposite sides of the two return springs 607 are respectively fixedly connected to the opposite sides of the two sliding plates 605. The positioning rod 606 facilitates the smooth movement of the sliding plate 605 and can drive the stable compression of the return spring 607 at the same time.

[0036] In addition, the positioning rod 606 is located on the back side of the corresponding trapezoidal limit block 608. The opposite sides of the two trapezoidal limit blocks 608 respectively extend into the inside of the corresponding docking groove 602. The front of the trapezoidal clamping block 604 can be attached to the front side of the same-side trapezoidal limit block 608. The inclined surfaces of the mutually attachable sides of the trapezoidal clamping block 604 and the trapezoidal limit block 608 facilitate the movement of the trapezoidal limit block 608 during pressing.

[0037] Meanwhile, the opposite ends of the two pressing rods 609 penetrate through the left and right sides of the main body 1 of the chassis respectively. Anti-slip blocks 7 are fixedly connected to both sides of the top of the box cover 2. The anti-slip blocks 7 are square blocks with irregular patterns on the surface. The pressing rods 609 facilitate the operation by the operator, and under the action of the anti-slip blocks 7, it is convenient for the operator to open the box cover 2.

[0038] In this embodiment, the vacuum pumping assembly 500 is a structure for pumping out air to achieve the effect of vacuum storage.

[0039] As Figure 1 、 Figure 2 and Figure 4 shown, the vacuum pumping assembly 500 includes a first vacuum frame 501 fixedly connected to the rear inner wall of the main body 1 of the chassis, a second vacuum frame 502 fixedly connected to the rear inner wall of the box cover 2, an exhaust valve 503 fixedly installed on the back of the box cover 2, a vacuum pressure sensor 504 fixedly installed on the rear inner wall of the main body 1 of the chassis and located inside the first vacuum frame 501, and two sealing rings 505 adhesively attached to the front of the first vacuum frame 501 and the front of the second vacuum frame 502 respectively; an installation groove 506 is formed on the back of the main body 1 of the chassis, and a small vacuum pump 507 is fixedly installed inside the installation groove 506.

[0040] It should be noted that the exhaust valve 503 is a manual or automatic valve capable of communicating two spaces. The end of the exhaust valve 503 penetrates through the back of the box cover 2 and extends into the interior of the second vacuum frame 502. By opening the exhaust valve 503, the outside can be communicated with the interior of the second vacuum frame 502, so that air can normally enter the interior of the second vacuum frame 502, and the relatively vacuum state can be released. The front of the top sealing ring 505 can be attached to the front of the bottom sealing ring 505, and the mutually attached sealing rings 505 can form a relatively sealed space between the interiors of the first vacuum frame 501 and the second vacuum frame 502.

[0041] In addition, the air extraction end of the small vacuum pump 507 penetrates through the back of the main body 1 of the chassis and extends into the interior of the first vacuum frame 501. The air inside the first vacuum frame 501 can be pumped out by the small vacuum pump 507.

[0042] Meanwhile, a baffle located outside the installation groove 506 is connected to the back of the main body 1 of the chassis by bolts. Exhaust holes are evenly distributed on the back of the baffle, and the air pumped into by the small vacuum pump 507 can be discharged through the exhaust holes.

[0043] It should also be noted that a small power supply is fixedly installed inside the chassis main body 1. All the electronic components and devices mentioned in the text are electrically connected to the small power supply. A charging interface that penetrates the top of the chassis main body 1 is installed on the top of the small power supply. The small power supply can supply electrical energy to the electronic components mentioned in the text, and the small power supply can be replenished with power through the charging interface.

[0044] The working principle of the above embodiment is as follows:

[0045] When it is necessary to seal the packaging bag, place the bag opening of the packaging bag on the front of the first vacuum frame 501, so that the bag opening is located inside the first vacuum frame 501. Close the lid 2 and press the lid 2 towards the side close to the chassis main body 1. The trapezoidal clamping block 604 will push the corresponding trapezoidal limiting block 608 to move, thereby driving the reset spring 607 to compress through the sliding plate 605. Under the elastic recovery action of the reset spring 607, the trapezoidal limiting block 608 will be driven by the sliding plate 605 to move to the front of the trapezoidal clamping block 604, so that the trapezoidal limiting block 608 can play a role in clamping and limiting the trapezoidal clamping block 604. At this time, the two sealing rings 505 are in an abutting state. Under the action of the sealing rings 505, the space between the inside of the first vacuum frame 501 and the second vacuum frame 502 can be separated from the outside world, so that the internal space forms a relatively closed state. Start the small vacuum pump 507 to pump out the air in the space between the inside of the first vacuum frame 501 and the second vacuum frame 502, and pump out the air in the packaging bag through this space and the bag opening to realize the vacuum preservation of the internal food. Under the action of the vacuum pressure sensor 504, the pressure inside this space can be monitored in real time. When the monitoring data reaches the preset value, start the hot pressing and sealing mechanism 4 to hot press and seal the packaging bag. Press the two pressing rods 609, so that the sliding plate 605 drives the corresponding reset spring 607 to compress, and the trapezoidal limiting block 608 is moved away from the corresponding trapezoidal clamping block 604, so that the clamping and limiting of the trapezoidal clamping block 604 can be smoothly released. At this time, just push the two anti-slip blocks 7 with the thumb, and the lid 2 can be easily separated from the chassis main body 1. After opening the lid 2, take out the sealed packaging bag.

[0046] Compared with the prior art, this vacuum packaging and sealing machine can more conveniently and gently open or close the vacuum packaging and sealing machine through the cooperation of the hot pressing and sealing mechanism 4, the vacuum pumping assembly 500 and the closing assembly 600 inside the chassis main body 1, without the need to force it open, thus avoiding the situation of being scalded by touching the heat source. At the same time, it is also convenient for the operator to perform the sealing operation, and can also connect the vacuum space with the outside world after the sealing is completed, further reducing the difficulty of opening, thereby effectively improving the practical performance of the vacuum packaging and sealing machine and solving the disadvantages that the existing vacuum packaging machine is inconvenient and prone to scalding during the opening process after the bag is sealed.
