[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] like Figure 1As shown, the vacuum packaging machine for the production of dried mushrooms includes a packaging machine body 1, a vacuum chamber 2 with an upper opening is provided inside the packaging machine body 1, a shell cover 3 which can seal the upper opening of the vacuum chamber 2 is installed on the upper part of the packaging machine body 1, so that the vacuum chamber 2 becomes a sealed structure, and a vacuum pump and a hot-pressing film-sealing mechanism 4 are installed inside the vacuum chamber 2. When the packaging bag with dried mushrooms is placed inside the vacuum chamber 2, the shell cover 3 is closed, and then the vacuum pump is started to extract the air inside the packaging bag, and then the hot-pressing film-sealing mechanism 4 is used to seal the packaging bag.

[0023] Here, the hot-pressing film-sealing mechanism 4 may be two vertically overlapping heating strips, and the heating strip on the upper side may be moved vertically. The opening of the packaging bag may be heated and sealed by the two heating strips.

[0024] In order to reduce the phenomenon of dry fungus materials being sucked out of the packaging bag during the vacuuming process, an adjusting bracket is installed inside the vacuum chamber 2, and a limiting pressure plate is installed on the adjusting bracket. At this time, the limiting pressure plate is pressed against the position of the packaging bag close to the opening, so that the dry fungus materials can be limited by the limiting pressure plate.

[0025] At the same time, if Figure 1 and Figure 3-4 As shown, the limiting pressure plate includes an upper pressure plate 6, and a plurality of air guiding holes 7 are opened on the lower side of the upper pressure plate 6. At this time, the position relative to the packaging bag and the air guiding holes 7 is not fully compacted, and gas can flow.

[0026] Among them, Figure 1 As shown, in order to make the height of the packaging bag compatible with the hot pressing film sealing mechanism 4, a lower pressing platform 5 is fixedly connected inside the vacuum chamber 2 and located at the lower side of the limiting pressing plate, and the height of the packaging bag can be effectively controlled by the upper pressing plate 6.

[0027] like Figure 1 and Figure 3-4 As shown, the adjustment bracket includes a vertical moving mechanism 9 installed inside the vacuum chamber 2. The vertical moving mechanism 9 can be a vertically arranged electric push rod. A horizontal bracket 8 is installed on the vertical moving mechanism 9, that is, the output end of the electric push rod is fixedly connected to the horizontal bracket 8. The number of limiting pressure plates is preferably multiple, and the multiple limiting pressure plates are assembled on the lower side of the horizontal bracket 8, so that the multiple limiting pressure plates can be driven to move synchronously to limit the multiple packaging bags.

[0028] Moreover, in order to make the height of the limiting pressure plate adjustable independently, a plurality of vertically arranged slide grooves are provided on the horizontal bracket 8, and a vertical slide plate 10 is vertically slidably connected inside each of the plurality of slide grooves. The lower end of the vertical slide plate 10 is fixedly connected to the limiting pressure plate. At this time, under the action of gravity, the limiting pressure plate will press and limit the packaging bag. When the limiting pressure plate needs to be adjusted separately, the vertical slide plate 10 can be pulled upward, and a pulling plate 11 is fixedly connected to the upper side of the vertical slide plate 10. When the horizontal bracket 8 moves upward, the pulling plate 11 can drive the vertical slide plate 10 and the limiting pressure plate to move together.

[0029] Furthermore, a tension spring 12 is installed between the pull plate 11 and the cross bracket 8. The force applied by the tension spring 12 to the limit pressing plate can make the limit pressing plate stably pressed on the packaging bag.

[0030] The working principle of the utility model is as follows: the shell cover 3 is opened, and then a plurality of packaging bags are placed near the opening on the hot pressing film sealing mechanism 4, and the packaging bags are placed on the lower pressing platform 5, and then the packaging bags are limited by the limiting pressing plate, so that the opening of the packaging bag is converted from a large opening to a plurality of small openings;

[0031] The shell cover 3 is closed, and then the vacuum pump is started to extract the air inside the packaging bag, and then the packaging bag is sealed using the hot pressing film sealing mechanism 4;

[0032] In summary, this technical solution converts the opening of the packaging bag from a large area opening to multiple small area openings by setting a limiting pressure plate, which can reduce the phenomenon of dry fungus materials being sucked out of the packaging bag due to vacuum suction during the vacuum packaging process.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
