Description

Technical Field

[0001] This utility model relates to the technical field of garbage bag packaging equipment, and in particular to an automatic vacuum packaging device. Background Technology

[0002] For example, a vacuum packaging device disclosed in invention patent application number 202311015439.7 mainly includes a shell, a clamp, a vacuuming mechanism, and a heating element. During operation, the clamp partially holds the garbage bag while simultaneously puncturing holes in the bag using a punch on the clamp. The vacuuming mechanism then creates a vacuum through the air extraction holes on the punches. Finally, the heating element melts the garbage bag, maintaining a vacuum seal. However, its structure is relatively complex. When the clamp holds the garbage bag too tightly, the holes are difficult to connect with the inside of the bag, making vacuuming difficult. When the clamp holds the garbage bag too loosely, gaps form between the clamp and the bag, allowing the holes to connect with the outside, resulting in air leakage during vacuuming and poor vacuum packaging performance. Utility Model Content

[0003] The main purpose of this invention is to propose an automatic vacuum packaging device, which aims to solve the problem that existing vacuum packaging devices are prone to air leakage during vacuuming, resulting in poor vacuuming effect.

[0004] To achieve the above objectives, this utility model proposes an automatic vacuum packaging device, comprising:

[0005] The housing has a receiving space for the plastic bag to be unfolded therein, and the receiving space is open at the top;

[0006] A vacuuming mechanism, comprising a vacuum pump disposed in the housing and a pipe connected to the vacuum pump, wherein the free end of the pipe extends into the plastic bag through the top opening of the accommodating space;

[0007] A pressing mechanism is provided in the receiving space and is used to press together a portion of the plastic bag and a portion of the pipe to isolate the inside of the plastic bag from the outside world, so that the vacuum pump can work with the pipe to evacuate the plastic bag.

[0008] A fusing mechanism is provided in the accommodating space below the pressing mechanism, and is used to partially press and fuse the plastic bag after vacuuming to complete vacuum packaging.

[0009] Preferably, the pressing mechanism includes a first fixing member fixedly disposed in the receiving space and a first moving member movably disposed in the receiving space. The first moving member can move relative to the shell between abutting and moving away from the first fixing member. When abutting, it can press together the plastic bag part and the pipe part. A first driving mechanism is provided to drive the first moving member to perform the movement.

[0010] Preferably, the first drive mechanism is a telescopic cylinder or a linear motor.

[0011] Preferably, the first fixing member and the first moving member are made of silicone. When the first fixing member and the first moving member press the plastic bag and the pipe together, the position of the first fixing member and the first moving member corresponding to the pipe is subjected to appropriate deformation, so as to completely fit with the pipe wall and avoid the situation where the vacuuming effect is poor due to gaps caused by incomplete fitting.

[0012] Preferably, the fusing mechanism includes a second fixing member fixedly disposed in the receiving space and a second moving member movably disposed in the receiving space. The second moving member can move relative to the housing between positions that abut against and move away from the second fixing member. The second moving member is a heating element or a heating element is provided on the side of the second moving member that abuts against the second fixing member. When the second moving member abuts against the second fixing member, the tape is partially pressed together, and then the fusing is achieved by heating. A second driving mechanism is provided to drive the second moving member to perform the aforementioned movement.

[0013] Preferably, the second drive mechanism is a telescopic cylinder or a linear motor.

[0014] Preferably, a bag box for containing plastic bags is also provided, the bag box being annular, located on the top of the housing, and surrounding the top opening of the containing space therein.

[0015] Preferably, the conduit includes a flexible tube and a rigid tube. One end of the flexible tube is connected to a vacuum pump, and the rigid tube is L-shaped, with one end abutting against the top wall of the bag and connected to the free end of the flexible tube, and the other end abutting against the inner side wall of the bag and extending into the receiving space.

[0016] Preferably, the vacuum pump is located in the receiving space, and a connection hole communicating with the receiving space is opened on the top of the housing corresponding to the position above the vacuum pump. The free end of the hose passes through the connection hole and is connected to the rigid pipe.

[0017] Preferably, one end of the rigid tube is provided with a connector, and the rigid tube is detachably connected to the free end of the flexible tube by inserting the connector.

[0018] This invention features a vacuuming mechanism, a pressing mechanism, and a fusing mechanism, all comprising a vacuum pump and a pipe, within the housing. The plastic bag can unfold within the housing's containment space to collect waste. One end of the pipe connects to the vacuum pump, while the other end extends into the plastic bag through the top opening of the containment space. When packaging the plastic bag, the pressing mechanism first presses the bag and a portion of the pipe together to seal the bag. Then, the vacuum pump evacuates the bag. Finally, the fusing mechanism below the pressing mechanism presses and fuses the portion of the bag to complete the vacuum packaging. Compared to traditional methods, this invention has a simpler overall structure. During the vacuuming process, it eliminates the need to create vents by damaging the bag, maintaining its integrity and preventing leaks. Furthermore, the secondary pressing by the pressing and fusing mechanisms ensures the bag's airtightness and improves the vacuuming effect. Attached Figure Description

A first driving mechanism (not shown) is provided to drive the first moving member 42 to perform the movement.

[0033] Specifically, the free end opening of the pipe must be located below the first moving part 42 to avoid the free end opening of the pipe being pressed by the pressing mechanism, which would prevent vacuuming from occurring.

[0034] Specifically, the first driving mechanism is a telescopic cylinder or a linear motor. The first moving part 42 is the driving end of the first driving mechanism, or the first moving part 42 is connected to the driving end of the first driving mechanism.

[0037] It should be noted that the heating element is existing technology, and its specific structure and principle will not be described in detail here.

[0038] Specifically, the first moving member 42 and the second moving member 52 can move synchronously or independently. When moving synchronously, the first moving member 42 abuts against the first fixed member 41 one position earlier than the second moving member 52. When the second moving member 52 abuts against the second fixed member 51, the first moving member 42 undergoes appropriate deformation.

[0039] Specifically, the second drive mechanism is a telescopic cylinder or a linear motor. The second moving part 52 is the drive end of the second drive mechanism, or the second moving part 52 is connected to the drive end of the second drive mechanism.

[0044] Specifically, the rigid tube 32 and the bag box 6 are either integrally formed or detachably fixedly connected.

[0045] Specifically, the vacuum pump 2 is located in the accommodating space, and a connection hole communicating with the accommodating space is opened on the top of the housing 1 at a position corresponding to the vacuum pump 2. The free end of the flexible tube 31 passes through the connection hole and is connected to the rigid tube 32.

[0046] Specifically, a limiting flange 311 is provided on the peripheral wall of the hose 31 near the free end of the hose 31 to abut against the top wall of the housing 1, thereby restricting the free end of the hose 31 from passing through the connection hole.

[0047] Specifically, one end of the rigid tube 32 is provided with a connector 321, and the rigid tube 32 is detachably connected to the free end of the flexible tube 31 by inserting the connector 321.

When packaging the plastic bag, the pressing mechanism first presses the bag and a portion of the pipe together to seal the bag. Then, the vacuum pump evacuates the bag. Finally, the fusing mechanism below the pressing mechanism presses and fuses the portion of the bag to complete the vacuum packaging. Compared to traditional methods, this invention has a simpler overall structure. During the vacuuming process, it eliminates the need to create vents by damaging the bag, maintaining its integrity and preventing leaks.
