DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following is a further detailed description of the present application in conjunction with the attached Figure 2-5 drawings.

[0033] An embodiment of the present application discloses a vacuum packaging device. Refer to Figure 2, the vacuum packaging device includes a frame 1, a workbench 2, a vacuum cover 3 and a control system; among them, the workbench 2 is a rectangular tabletop and is fixed on the frame 1, the vacuum cover 3 is rotatably arranged on the workbench 2 by means of a connecting rod 81, the upper surface of the workbench 2 is provided with working areas at both ends respectively, and the vacuum cover 3 can be rotated to cover the two working areas respectively, so as to evacuate and seal the packaging bags placed on the two working areas; the control system is used to control the operation of the vacuum cover 3.

[0034] Referring to Figure 2 and Figure 3 , in this embodiment, a heating strip 22 is also fixed on the upper surface of the workbench 2 by means of bolts or the like. The length direction of the heating strip 22 is parallel to the length direction of the workbench 2. Two heating strips 22 are arranged in parallel in each working area, and the two heating strips 22 are respectively located on both sides of the workbench 2, so that two rows of packaging bags can be placed at the same time for sealing.

[0035] Referring to Figure 2 , in this embodiment, the vacuum packaging device further includes a conveyor belt 4 and an aggregate box 5. Among them, the aggregate box 5 is arranged at both ends of the workbench 2 respectively; there are two conveyor belts 4 arranged on the workbench 2, and they are respectively arranged corresponding to the two working areas. The conveyor belt 4 is located between the two heating strips 22. During use, the packaging bag is placed on the conveyor belt 4, and the opening of the packaging bag faces the direction of the heating strip 22. When the sealing is completed, the conveyor belt 4 is started, and the packaged fish can be conveyed to the end of the workbench 2 and fall into the aggregate box 5, so as to improve the discharging efficiency after the fish is packaged.

[0036] Referring to Figure 2 and Figure 3 , in this embodiment, a guide plate 21 can be inclinedly arranged at the end of the workbench 2. The upper end of the guide plate 21 is fixed to the side wall of the end of the workbench 2, and the lower end of the workbench 2 extends obliquely downward into the aggregate box 5, so that the packaging bag can fall into the aggregate box 5 along the guide plate 21. Further, baffles are fixed on both sides of the guide plate 21 by welding or the like, which can prevent the packaging table from slipping out of the guide plate 21 from the side.

[0037] Referring to Figure 2 , in this embodiment, the aggregate box 5 can be a rectangular box body with a hollow interior and an open upper end. The lower surface of the aggregate box 5 is connected with pulleys, and the pulleys can be universal wheels with brakes; a handle can be arranged on the side wall of the aggregate box 5, so that when the aggregate box 5 is full, it is convenient to replace a new aggregate box 5.

[0038] Referring to Figure 3 and Figure 4, in this embodiment, a positioning device 6 for positioning the packaging bags is provided on the surface of the conveyor belt 4. Two sets of the positioning device 6 can be provided on the conveyor belt 4. When one set is located on the upper surface of the conveyor belt 4, the other set can be exactly located on the lower surface of the conveyor belt 4. Specifically, the positioning device 6 includes two positioning bars 61 fixed on the surface of the conveyor belt 4, and a partition bar 62 arranged between the two positioning bars 61. Both of the two positioning bars 61 are arranged along the width direction of the conveyor belt 4, and the positions of the two positioning bars 61 correspond to the two ends of the heating bar 22. The partition bar 62 is arranged at intervals between the two heating bars 22, so as to cooperate with the positioning bars 61 to form a material placing cavity for placing the packaging bags. Each packaging bag containing fish is respectively placed between different material placing cavities, so that not only can the position of the packaging bag be quickly positioned, but also the movement of the packaging bag can be restricted during packaging, improving the packaging effect.

[0039] The partition bar 62 can be fixed on the surface of the conveyor belt 4 or can be detachably fixed. In this embodiment, the partition bar 62 adopts a detachable fixing method. Specifically, the positioning device 6 further includes positioning bolts 63. The positioning bolts 63 are respectively arranged at both ends of the partition bar 62. Threaded holes for the threaded connection of the positioning bolts 63 are provided on the surface of the conveyor belt. The threaded holes are arranged at intervals between the two positioning bars 61 along the conveying direction of the conveyor belt 4. Passing the positioning bolts 63 through the partition bar 62 and threadedly connecting them with the corresponding threaded holes can fix the partition bar 62 on the conveyor belt 4. And by changing the position where the positioning bolts 63 are fixed on the conveyor belt 4, the distance between two adjacent partition bars 62 can be adjusted, that is, the size of the space for placing the packaging bags can be adjusted, so as to adapt to different fish packaging.

[0040] Refer to Figure 3 and Figure 4 , in this embodiment, the cross-section of the heating bar 22 can be rectangular. Guide plates 7 can be provided on the sides of the two heating belts facing the conveyor belt 4. The upper ends of the guide plates 7 are fixed to the heating bar 22 by bolts or welding, etc., and the lower ends are obliquely downward and fixed to the upper surface of the workbench 2. Through the guide plates 7, when the vacuum cover 3 presses down to heat-seal the packaging bag, the possibility of the packaging bag being pressed out with indentations by the edges of the heating bar 22 can be reduced.

[0041] Refer to Figure 3 and Figure 4, in this embodiment, a pressure bar 8 is rotatably arranged on the heating bar 22, and a driving member 9 for driving the pressure bar 8 exclusively is arranged on the workbench 2; the pressure bar 8 is a cylindrical long bar, and the length direction of the pressure bar 8 is parallel to the length direction of the heating bar 22. Both ends of the pressure bar 8 are fixedly connected with connecting rods 81. One end of the connecting rod 81 far from the pressure bar 8 is fixedly connected with a rotating shaft 82. The length direction of the rotating shaft 82 is parallel to the length direction of the pressure bar 8. One end of the rotating shaft 82 is rotatably connected to the side wall of the heating bar 22, and the other end of the rotating shaft 82 extends in a direction away from the side wall of the heating bar 22 and passes through the connecting rod 81. The driving member 9 can drive the rotating shaft 82 to rotate, thereby driving the connecting rod 81 to rotate; when the packaging bag is placed on the workbench 2, the pressure bar 8 can be rotated and pressed on the packaging bag, so that the lower surface of the packaging bag abuts against the upper surface of the guide plate 7, thereby being able to position the packaging bag and limit the movement of the packaging bag; after heat sealing is completed, the vacuum cover 3 pops up, and the driving member 9 drives the pressure bar 8 to rotate in the reverse direction to release the packaging bag, and the conveyor belt 4 can then send the package into the aggregate frame 5.

[0042] Refer to Figure 4 and Figure 5 , in this embodiment, the driving member 9 includes a motor 91, a pulley 92 and a synchronous belt 93. Among them, the motor 91 can be a micro motor 91. The motor 91 can be embedded in the workbench 2. There are two pulleys 92. One of them is coaxially and fixedly connected to the output end of the motor 91. The end of the rotating shaft 82 away from the heating bar 22 passes through the connecting rod 81 and is coaxially fixed to the other pulley 92. The synchronous belt 93 is wound around the two pulleys 92. A space for the pulley 92 to pass through is provided on the work bar. Thus, when the motor 91 is started, through the transmission of the pulley 92 and the synchronous belt 93, the rotating shaft 82 can be driven to rotate, thereby driving the connecting rod 81 to rotate. The driving member 9 can be arranged at one end of the heating bar 22, or can be arranged at both ends of the heating bar 22 respectively.

[0043] The implementation principle of a vacuum packaging device in an embodiment of the present application is as follows: when packaging fish, first place the packaging bag containing the fish between the two partition bars 62 and between the partition bar 62 and the positioning bar 61, and make the opening of the packaging bag cross over the heating bar 22. Then start the motor 91 to drive the pressure bar 8 to rotate and press on the packaging bag, and then control the vacuum cover 3 to rotate and press on the packaging bag for heat sealing. After completion, the vacuum cover 3 pops up upward, the motor 91 drives the pressure bar 8 to rotate in the reverse direction, and the conveyor belt 4 starts to drive the packaging bag to rotate and fall into the aggregate frame 5.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
