[0042] The specification can use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which can refer to one or more embodiments of the application.

[0043] The disclosed embodiments provide a vacuum packaging machine, such as Figures 1 to 15As shown, it includes a base plate 11, on which a housing 1 is disposed. The housing 1 has a top plate 12. The base plate 11 and the top plate 12 can be, for example, rectangular. A plurality of sidewalls 13 are disposed between the base plate 11 and the top plate 12. These sidewalls 13 are sequentially connected and cooperate with the top plate 12 to form the housing 1. In this embodiment, the size of the base plate 11 is larger than the size of the top plate 12, so that the housing 1 is disposed on a portion of the base plate 11. The sidewalls 13 located on both sides and the rear are perpendicular to the base plate 11, while the sidewalls 13 located at the front are inclined to the base plate 11.

[0044] Furthermore, a sealing platform 14 is provided on the outer side of the housing 1 at the front of the base plate 11. A pressure block 2 is provided on the sealing platform 14. The pressure block 2 can rotate relative to the housing 1 and press against the sealing platform 14. Thus, when sealing the package, the opening of the package is placed on the sealing platform 14 and below the pressure block 2. By rotating the pressure block 2 relative to the housing 1 to open or close the package, the opening of the package is pressed tightly against the sealing platform 14 to achieve a seal. Then, a vacuuming operation can be performed on the package.

[0045] Preferably, sensors 131 are provided on the inner sides of the two opposing sidewalls 13 near the sealing platform 14. The sensors 131 are used to detect whether there are foreign objects on the sealing platform 14. For example, they can prevent the operator's hands from being placed on the sealing platform 14 and causing injury. The sensors 131 can be photoelectric sensors. For example, a photoelectric transmitter can be provided on one sidewall 13 and a photoelectric receiver can be provided on the opposite sidewall 13. When there are foreign objects on the sealing platform 14, they will block the transmission of photoelectric signals, thereby controlling the pressure block 2 to stop rotating.

[0046] like Figure 4 As shown, the upper surface of the sealing platform 14 is opposite to the lower surface of the pressure block 2. A first sealing groove 141 is provided on the upper surface of the sealing platform 14, and a vacuum extraction hole is provided at the bottom of the first sealing groove 141. The vacuum shaft hole is connected to the pump inside the housing 1. A second sealing groove 21 is provided on the lower surface of the pressure block 2. When the pressure block 2 is pressed on the sealing platform 14, the first sealing groove 141 and the second sealing groove 21 are pressed together to form a sealing cavity 22. The sealing cavity 22 can be vacuumed through the vacuum extraction hole.

[0047] Further, a cutting assembly is arranged on the top plate 12, and the cutting assembly is used to cut the seal of the packaged product. Specifically, the cutting assembly comprises a pressing cover 6 and a pressing groove 3 matched with the pressing cover 6. The pressing cover 6 is arranged on the outside of the top plate 12 and extends along the length direction of the shell 1. One side edge of the pressing cover 6 is rotatably connected with the top plate 12. The pressing groove 3 is arranged on the surface of the top plate 12. The pressing cover 6 can rotate relative to the top plate 12 and press into the pressing groove 3. The seal of the packaged product is fixed by the cooperation of the pressing cover 6 and the pressing groove 3. The cutting member 8 is arranged on the pressing cover 6 and can cut the seal of the packaged product after the seal is fixed.

[0048] Specifically, the pressing cover 6 is provided with a hollow slide rail 61. The cutting member 8 is arranged on the slide rail 61 and can reciprocally slide along the length direction of the shell 1. When the cutting operation is performed, the seal of the packaged product is fixed on the pressing groove 3. The seal of the packaged product is pressed by the rotation of the pressing cover 6 and is cut by the sliding of the cutting member 8.

[0049] Further, the driving assembly 4 is arranged in the cavity. The driving assembly 4 is particularly arranged on the bottom plate 1 and is used to drive the pressing block 2 to rotate relative to the shell 1. Specifically, the driving assembly 4 comprises a first driving device 41 and at least one first transmission assembly which are connected with each other. The first driving device 41 is arranged on the bottom plate 11 of the shell 1. The first driving device 41 can be, for example, a motor. The output shaft of the first driving device 41 is connected with the first transmission assembly. The first transmission assembly is connected with the pressing block 2. The first driving device 41 outputs torque to drive the first transmission assembly to move. Then, the first transmission assembly drives the pressing block 2 to rotate, so as to open or close the pressing block 2.

[0050] The first transmission assembly can be one or more. In order to increase the driving force of the pressing block 2, the driving assembly 4 comprises a plurality of first transmission assemblies which are connected with the first driving device 41. The reduction device 45 can be connected with the pressing block 2 through the plurality of first transmission assemblies. Thus, the first driving device 41 can open or close the pressing block 2 through the plurality of first transmission assemblies.

[0051] In the embodiment, two first transmission assemblies are arranged side by side on the bottom plate 1. The two first transmission assemblies are respectively connected with two ends of the pressing block 2, so as to drive the pressing block 2 to rotate from two different positions. Preferably, the two first transmission assemblies are connected with each other to realize common movement.

[0052] Specifically, each of the first transmission assemblies comprises a first rotating shaft 42, a connecting rod 43 and a lever 44, wherein the first driving device 41 is connected with one end of the first rotating shaft 42 to drive the first rotating shaft 42 to rotate, and the first rotating shaft 42 can be arranged on the bottom plate 11 through a rotating shaft support seat for example. The other end of the first rotating shaft 42 is provided with an oscillating piece 421, which can be an S-shaped structure for example. When the first rotating shaft 42 rotates, the oscillating piece 421 rotates around the axis of the first rotating shaft 42, and the first rotating shaft 42 and the oscillating piece 421 can be assembled separately or integrally.

[0053] In the embodiment, the first rotating shafts 42 in the two first transmission assemblies can be coaxially connected or adopt an integral structure, for example, a shaft coupling 45 is arranged between the two first rotating shafts 42 to make the two first rotating shafts 42 rotate synchronously.

[0054] Further, the oscillating piece 421 is connected with the first end of the lever 44 through the connecting rod 43, the middle part of the lever 44 is arranged on the bottom plate 11 of the shell 1 and can rotate relative to the bottom plate 11, and the second end of the lever 44 penetrates through the side wall 13 and is connected with the pressing block 2 outside the side wall 13. When the oscillating piece 421 oscillates, the pressing block 2 can be driven to move through the lever 44. The lever 44 is preferably in a T-shaped structure, the two ends of the horizontal side of which are connected with the connecting rod 43 and the pressing block 2 respectively, and the vertical side thereof is rotatably connected with the bottom plate 11. Thus, when one end of the lever 44 moves downward for example, the other end of the lever 44 moves upward based on the lever action. By arranging the lever 44, the movement of the pressing block 2 can be driven by a smaller force on one side of the oscillating piece 421.

[0055] Further, the first end of the connecting rod 43 is rotatably connected with the oscillating piece 421, and the second end of the connecting rod 43 is rotatably connected with the first end of the lever 44. In an embodiment, the connecting rod 43 comprises a strip-shaped connecting rod body, the first end of the connecting rod body is provided with a first connecting hole, the second end of the connecting rod body is provided with a second connecting hole, the oscillating piece 421 can be inserted into the first connecting hole at the first end of the connecting rod body to achieve rotatable connection with the oscillating piece 421, and the second connecting hole at the second end of the connecting rod body is connected with the lever 44 rotatably through a fastener.

[0056] In another embodiment, the first end of the connecting rod body is provided with a first connecting hole, and the second end of the connecting rod body is provided with a slot, wherein the swing member 421 can be inserted into the first connecting hole at the first end of the connecting rod body, and the first end of the lever 44 is inserted into the slot at the second end of the connecting rod body and is rotatably connected to the second end of the connecting rod body by a fastener, so that the rotation of the swing member 421 can drive the first end of the lever 44 to move to one side or the other side through the connecting rod 43.

[0057] Further, the middle part of the lever 44 is arranged on the bottom plate 11 of the housing 1 through a lever mounting seat 15, and the distance between the lever mounting seat 15 and the first end or the second end of the lever 44 can be set according to the required force. Specifically, the lever mounting seat 15 and the middle part of the lever 44 are rotatably connected through a pin shaft, or the lever mounting seat 15 is provided with a mounting groove, and a second rotating shaft is arranged in the mounting groove, and the middle part of the lever 44 is inserted into the mounting groove and is rotatably connected to the second rotating shaft, so that the lever 44 can rotate relative to the second rotating shaft. The above structure can drive the second end of the lever 44 to move to the other side when the first end of the lever 44 moves to one side, thereby realizing the rotation of the pressing block 2.

[0058] In use of the vacuum packaging machine, the rotation of the first rotating shaft 42 drives the rotation of the swing member 421, and then drives the first end of the lever 44 to move to one side or the other side through the connecting rod 43, and the second end of the lever 44 is driven to move to one side or the other side based on the lever action of the middle part of the lever 44, thereby driving the rotation of the pressing block 2, and finally realizing the opening or closing of the pressing block 2.

[0059] Further, in order to control the output of the first driving device 41, a speed reduction device 46 is arranged between the first driving device 41 and the first rotating shaft 42, and the speed reduction device 46 can be a gear box, for example, which can adjust the torque output by the first driving device 41.

[0060] Further, a gear set 47 can be arranged between the output shaft of the speed reduction device 46 and the first rotating shaft 42, and the gear set 47 can ensure that power is quickly transmitted from the speed reduction device 45 to the first rotating shaft 42 without power loss.

[0061] In addition, in order to detect the movement of the lever 44, a detection device 48 is arranged on the bottom plate 11, and the detection device 48 can detect the degree of movement of the lever 44.

[0062] Further, the first driving device 41 also has a self-locking function, for example, a self-locking motor is adopted, and here, since the first driving device 41 has a self-locking function, for example, the self-locking triggering condition of the first driving device 41 can be associated with the state of the pressing block 2, for example, when the pressing block 2 is manually opened or closed, the corresponding rotating action of the connecting rod 43 triggers the self-locking of the first driving device 41, so that the first rotating shaft 42 cannot rotate; in addition, by triggering the self-locking, the internal circuit of the vacuum packaging machine can also be disconnected, for example, when the pressing block 2 is in an open state, the self-locking function of the first driving device 41 is triggered to make the vacuum packaging machine achieve power-off, so that the pressing block 2 cannot be accidentally closed under the driving of the first driving device 41. In addition, since the first driving device 41 is connected to the pressing block 2 through the first transmission assembly, when the first driving device 41 triggers the self-locking, the opening or closing of the pressing block 2 can be manually controlled.

[0063] In the embodiment, when two first transmission assemblies are adopted, the two first transmission assemblies can be symmetrically arranged relative to the first driving device 41, and the power output by the first driving device 41 is transmitted to the speed reducer 46, wherein the output shaft of the speed reducer 46 is connected to the shaft coupling 45 through the gear set 47, and the shaft coupling 45 coaxially connects the two first rotating shafts 42.

[0064] Here, the two first transmission assemblies are respectively connected to the pressing block 2, so that the torque output by the speed reducer 46 is transmitted through the two first transmission assemblies. Here, the first rotating shafts 42 of the two first transmission assemblies are coaxially arranged. In this way, the torque is transmitted to the two first transmission assemblies by the first driving device 41, and then the movement of the two first transmission assemblies drives the movement of the pressing block 2, which can significantly improve the driving force of the pressing block 2. When the opening torque of the pressing block 2 is constant, the first driving device 41 can output smaller torque to the corresponding position of the lever 44 through the two first transmission assemblies, so as to drive the opening or closing of the pressing block 2.

[0065] The transmission assembly of the embodiment of the present disclosure can realize the opening or closing of the pressing block of the vacuum packaging machine based on a smaller torque, and has the advantages of simple structure, convenient operation, prevention of accidental closing of the pressing block, and high safety.

[0066] Further, in order to realize the air guiding during the vacuumizing operation, at least one air guiding nozzle assembly 5 is arranged on the bottom plate 11.

The two ends of the box body 51 are open, a second driving device 52 is arranged at the first end of the box body 51, and a sealing seat 53 is arranged at the second end of the box body 51. The sealing seat 53 is arranged on the bottom plate 1, and the air guiding nozzle 55 can pass through the sealing seat 53.

[0068] Further, a second transmission assembly is arranged in the box body 51, the air guiding nozzle 55 is arranged on the second transmission assembly, the second transmission assembly is connected with the second driving device 52, and under the driving of the second driving device 52, the second transmission assembly can drive the air guiding nozzle 55 to move towards the direction of the pressing block 2. In addition, a second speed reduction device 57 can be arranged between the second transmission assembly and the second driving device 52, and the power output by the second driving device 52 can be adjusted through the second speed reduction device 57.
