[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] See also Figures 1 to 4 As shown, one embodiment of the present application discloses a small package sealing and forming machine, including: a box assembly, a bag clamping and feeding device 200, a heat sealing assembly 300 and a vacuum system 400.

[0036] Specifically, the box assembly includes a box body 110, a first switch structure 120 and a second switch structure 130. The box body 110 has a accommodating cavity 111. The accommodating cavity 111 has a first opening and a second opening. The first switch structure 120 is used to control the opening and closing of the first opening, and the second switch structure 130 is used to control the opening and closing of the second opening. The bag clamping device 200 is arranged on one side of the box body 110, and the bag clamping device 200 is used to deliver the packaging bag into the accommodating cavity 111; the heat sealing assembly 300 is arranged in the accommodating cavity 111, and the heat sealing assembly 300 is used to heat seal the packaging bag located in the accommodating cavity 111; the vacuum system 400 is connected to the accommodating cavity 111, and is used to control the vacuum degree of the accommodating cavity 111.

[0037] In the small package sealing and forming machine provided in the embodiment of the present application, when heat-sealing the packaging bag, the packaging bag to be heat-sealed is sent into the accommodating cavity 111 of the box body 110 by using the bag clamping device 200, and then the first switch structure 120 and the second switch structure 130 are controlled to close the first opening and the second opening of the accommodating cavity 111, so that the accommodating cavity 111 forms a closed sealed cavity, and then the vacuum system 400 is started to evacuate the accommodating cavity 111 to discharge the air in the accommodating cavity 111, and then the packaging bag is heat-sealed by using the heat sealing assembly 300. In this way, the gas in the packaging bag can be discharged, thereby reducing the gas content in the packaging bag.

[0038] In some embodiments of the present application, see Figure 1 and Figure 2 The bag clamping device 200 includes a first conveying mechanism 211, a multi-stage bag feeding mechanism 220 and a driving mechanism 230. The first conveying mechanism 211 is arranged horizontally, and the multi-stage bag feeding mechanism 220 is located above the first conveying mechanism 211. The driving mechanism 230 is used to drive the multi-stage bag feeding mechanism 220 to move, so that the multi-stage bag feeding mechanism 220 reciprocates between the accommodating cavity 111 and the position above the first conveying mechanism 211. In practical applications, the packaging bag to be heat-sealed is placed on the first conveying mechanism 211, and the sealing of the packaging bag to be heat-sealed is clamped and fixed by the multi-machine bag feeding mechanism. Then, the first conveying mechanism 211 and the multi-stage bag feeding mechanism 220 are synchronously moved into the accommodating cavity 111 to transfer the packaging bag to be heat-sealed into the accommodating cavity 111. In this process, the multi-stage bag feeding mechanism 220 can clamp and fix the sealing of the packaging bag, which can effectively avoid the deformation of the packaging bag, and is also conducive to keeping the sealing to be heat-sealed at the heat sealing station, thereby ensuring the heat sealing effect. At the same time, during this process, the staff does not need to enter the box body 110, which can effectively avoid possible dangers and help improve safety performance.

[0039] In some embodiments of the present application, the multi-stage bag feeding mechanism 220 includes a clamping assembly, which is connected to the driving mechanism 230 and is used to clamp the sealing portion of the packaging bag. In this way, the packaging bag to be heat-sealed can be clamped and fixed by the clamping assembly, so that the packaging bag maintains its shape during the conveying process, thereby ensuring the heat sealing effect.

[0040] In a possible implementation, the clamping assembly includes a finger cylinder, which opens and closes to clamp the seal of the packaging bag.

[0041] Furthermore, the bag clamping device 200 includes a transfer mechanism, which is connected to the multi-stage bag feeding mechanism 220. The transfer mechanism drives the multi-stage bag feeding mechanism 220 to reciprocate between the loading station and the accommodating cavity 111 to deliver the packaging bags to be packaged from the loading station into the accommodating cavity 111.

[0042] In a possible implementation, the transfer mechanism includes a driving member and a conveyor belt, wherein the driving member is used to drive the conveyor belt to reciprocate. The multi-stage bag feeding mechanism 220 is connected to the conveyor belt, and the reciprocating motion of the conveyor belt can drive the multi-stage bag feeding mechanism 220 to move between the loading station and the accommodating chamber 111. The driving member can be a servo motor.

[0043] In some embodiments of the present application, see Figure 1 and Figure 2 The first switch structure 120 includes a first door body 123 and a first moving mechanism, the first moving mechanism is installed on the box body 110, and the first moving mechanism is used to drive the first door body 123 to move. The first door body 123 is sealed and connected to the first opening of the box body 110 to ensure the sealing performance when the first opening is in a closed state.

[0044] In one possible implementation, see Figure 1 and Figure 2 The first moving mechanism is used to drive the first door body 123 to move in the vertical direction. When the first opening is in the open state, the first door body 123 is located above the first opening. Therefore, the space occupied by the first door body 123 in the plane projection can be reduced.

[0045] In this embodiment, the first moving mechanism includes a first cylinder 121 and a first slide rail 122. The first slide rail 122 is installed on the box body 110 and extends in the vertical direction. The first door body 123 is slidably connected to the first slide rail 122. The output end of the first cylinder 121 is connected to the first door body 123. The first cylinder 121 drives the first door body 123 to slide by telescoping.

[0046] In some embodiments of the present application, see Figure 1 and Figure 2The second switch structure 130 includes a second door body and a second moving mechanism, the second moving mechanism is installed on the box body 110, and the second moving mechanism is used to drive the second door body to move. The second door body is sealed and connected to the second opening to ensure the sealing performance when the second opening is closed.

[0047] In one possible implementation, please continue to see Figure 1 and Figure 2 The second moving mechanism is used to drive the second door body to move in the vertical direction. When the second opening is in the open state, the second door body is located above the second opening. Therefore, the space occupied by the second door body in the plane projection can be reduced.

[0048] In this embodiment, the second moving mechanism includes a second cylinder and a second slide rail. The second door body is slidably connected to the second slide rail. The output end of the second cylinder is connected to the second door body. The second cylinder drives the second door body to move by telescoping.

[0049] In this embodiment, the first opening and the second opening are respectively arranged on two oppositely arranged sides of the box body 110. Specifically, the first opening is located on one of the sides, and the second opening is located on the opposite side of the first opening. In this way, the packaging bag can be directly put in and taken out.

[0050] In some embodiments of the present application, see Figure 1 , Figure 2 and Figure 4 The first conveying mechanism 211 is disposed on one side of the box body 110, wherein the first opening is located in the conveying direction of the first conveying mechanism 211. The first conveying mechanism 211 is located at a loading station. In practical applications, the packaging bag to be sealed is placed on the first conveying mechanism 211, and the sealing of the packaging bag is clamped by the bag clamping device 200, and then the packaging bag is jointly delivered to a designated position in the accommodating cavity 111, namely, the heat sealing station.

[0051] In some embodiments of the present application, the box assembly includes a horizontal conveying mechanism, which is disposed in the box body 110. The horizontal conveying mechanism is flush with the first conveying mechanism 211 to facilitate the heat-sealed packaging bag to be conveyed from the first conveying mechanism 211 to the horizontal conveying mechanism.

[0052] In some embodiments of the present application, see Figure 1 , Figure 2 and Figure 4 The bag clamping device 200 further includes a second conveying mechanism 212, which is disposed on one side of the box body 110, and whose height is flush with the horizontal conveying mechanism. In this way, the heat-sealed packaging bag can be conveniently transferred out of the accommodating cavity 111.

[0053] In this embodiment, the first conveying mechanism 211, the horizontal conveying mechanism and the second conveying mechanism 212 are arranged in a straight line, and the first opening and the second opening of the box body 110 are arranged on two opposite sides of the box body 110. In this way, the efficiency of loading and unloading can be improved.

[0054] Another aspect of the present application discloses a packaging method, which is applied to the aforementioned small package sealing and forming machine, comprising the following steps:

[0055] The packaging bag to be sealed is sent into the accommodating chamber 111 through the bag clamping and conveying device 200, and the first opening and the second opening are closed;

[0056] The vacuum system 400 is started to evacuate the receiving chamber 111 until the vacuum degree in the receiving chamber 111 reaches a target value;

[0057] Start the heat sealing assembly 300 to heat seal the seal of the packaging bag;

[0058] The vacuum system 400 is controlled to adjust the vacuum degree of the receiving chamber 111 to a second vacuum value, that is, the receiving chamber 111 is changed from a vacuum state to a normal pressure.

[0059] In the embodiment of the present application, the functions of automatic conveying of small packaged materials, automatic vacuuming, pressure maintenance, heat sealing and bag shaping can be realized, with a high degree of automation, good vacuum degassing effect, and effective sedimentation of the material height. At the same time, the staff does not need to enter or carry the materials into the box body 110, which can reduce possible dangers and improve safety.

[0060] It should be noted that after the packaging bag is heat-sealed in the containing cavity 111, the vacuum system 400 needs to be used to break the vacuum in the containing cavity 111, that is, to restore the air pressure in the containing cavity 111 to atmospheric pressure, and then control the first opening and / or the second opening to open for subsequent work.
