Description

Technical Field

[0001] The utility model relates to a pneumatic vacuum packaging machine, in particular to a pneumatic vacuum packaging machine with a positioning function. Background Art

[0002] A pneumatic vacuum packaging machine uses compressed air as a power source to perform vacuum extraction and sealing operations. These machines are widely used in industries such as food, medicine, and electronics to extend product shelf life, maintain freshness, and prevent oxidation and deterioration. They operate by using a vacuum pump to extract air from the bag, creating a certain vacuum. A heating element then seals the bag's opening, achieving a hermetic seal.

[0003] Traditional vacuum packaging machines have a simple structure. When packaging items, the items are usually placed on a platform, the bag opening is tightened, and the bag is inserted into the packaging machine for vacuum packaging. However, this method has some drawbacks:

[0004] 1. Without a positioning component, larger bags (such as bags containing rice) are prone to tipping over on the platform, especially during placement and vacuuming. In addition, the contents of the bag may be unevenly distributed due to movement, resulting in one side being too heavy, affecting the packaging effect;

[0005] 2. Operators need to frequently adjust the position of the bag to ensure its stability on the platform, which wastes a lot of time and labor and reduces production efficiency;

[0006] 3. The instability of the bag on the platform may cause the bag opening to not fit tightly against the sealing strip, thereby affecting the vacuum sealing effect, increasing the risk of air leakage, and reducing packaging quality. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings, the technical problem of the present invention is to provide a pneumatic vacuum packaging machine with a positioning function.

[0008] The technical solution is: a pneumatic vacuum packaging machine with a positioning function, including a shell, a controller, a vacuum component, a material frame, a damper, a discharge plate, a connecting plate, a clamping plate and a power component. The controller is installed on the left side of the shell, and the vacuum component is installed on the upper side of the shell. The vacuum component is electrically connected to the controller. The material frame is placed at the bottom of the shell. The bottom of the material frame is connected to the discharge plate through multiple dampers. A spring is connected inside the damper. The rear side of the material frame is symmetrically slidably connected to the connecting plate. The front side of the connecting plate is connected to the clamping plate. The clamping plates are located on both sides of the material frame. A power component is provided on the material frame.

[0009] More preferably, the power assembly includes a bidirectional cylinder and a connecting frame, the connecting frame is connected to the rear side of the material frame, the bidirectional cylinder is installed on the connecting frame, the two telescopic rods of the bidirectional cylinder are connected to the connecting plate on the same side, and the bidirectional cylinder is electrically connected to the controller.

[0010] More preferably, it also includes a top plate, a rubber plate, a torsion spring and a top block. The outer side of the clamping plate is connected to the top plate, the front side of the material frame is symmetrically rotatably connected to the rubber plate, two torsion springs are connected between the rubber plate and the material frame, and the outer side of the rear of the rubber plate is connected to the top block.

[0011] More preferably, the top block is arranged obliquely, and the top plate contacts and cooperates with the top block on the same side.

[0012] More preferably, it also includes a motor, a rotating plate and a limit plate. The motor is installed on the right rear side of the top of the material frame, the rotating plate is connected to the motor output shaft, and the limit plate is connected to the rear side of the top of the material frame. The limit plate and the rotating plate are in the same horizontal plane, and the angle between the two is 90 degrees. The motor is electrically connected to the controller.

[0014] Compared with the existing technology, the utility model has the following advantages: 1. By setting the clamping plate to clamp the two sides of the article, and the rubber plate blocking the front of the material frame, the article is positioned in all directions, which can ensure the stability of the article after placement and is not easy to tip over during the vacuum packaging process, which helps to evenly distribute the articles in the bag and improve the packaging quality;

[0015] 2. A limit plate is set to limit the position of the bag opening, and the rotating plate can automatically tighten the bag opening, eliminating the need to manually press the bag opening for vacuum packaging. This not only provides convenience for staff, but also improves safety during operation and reduces human errors.

The controller 2 is installed on the left side of the shell 1 by bolts, and the vacuum component 3 is installed on the upper side of the shell 1 by bolts. The vacuum component 3 is electrically connected to the controller 2. The material frame 4 is placed at the bottom of the shell 1. The bottom of the material frame 4 is connected to a discharge plate 8 for placing articles through multiple dampers 7. The damper 7 is connected with a spring for buffering the discharge plate 8. The connecting plate 11 is symmetrically slidably connected to the left and right rear sides of the material frame 4. The front sides of the connecting plates 11 are connected to clamping plates 12 for clamping articles. The clamping plates 12 are located on the left and right sides of the material frame 4. The material frame 4 is provided with a power component.

[0024] like Figure 3 As shown, the power assembly includes a bidirectional cylinder 9 and a connecting frame 10. The connecting frame 10 is connected to the rear side of the material frame 4. The bidirectional cylinder 9 is installed on the connecting frame 10 by bolts. The left and right telescopic rods of the bidirectional cylinder 9 are connected to the connecting plate 11 on the same side. The bidirectional cylinder 9 is electrically connected to the controller 2.

[0025] like Figure 3 and Figure 4As shown, it also includes a top plate 13, a rubber plate 14, a torsion spring 15 and a top block 16. The top plate 13 is welded to the outside of the clamping plate 12. The front side of the material frame 4 is symmetrically and rotatably connected to the rubber plate 14 for preventing the items from tipping over. Two torsion springs 15 are connected between the rubber plate 14 and the material frame 4. The outer side of the rear of the rubber plate 14 is welded with a top block 16. The top block 16 is arranged obliquely. The top plate 13 contacts and cooperates with the top block 16 on the same side, and can drive the rubber plate 14 to rotate by pushing the inclined surface of the top block 16.

[0026] like Figure 4 As shown, it also includes a motor 17, a rotating plate 18 and a limit plate 19. The motor 17 is installed on the right rear side of the top of the material frame 4 by bolts. The rotating plate 18 for tightening the bag opening is connected to the output shaft of the motor 17. The limit plate 19 for limiting the position of the bag opening is welded on the rear side of the top of the material frame 4. The limit plate 19 and the rotating plate 18 are in the same horizontal plane, and the angle between the two is 90 degrees. The motor 17 is electrically connected to the controller 2.

[0027] like Figure 1-Figure 2 As shown, it also includes an electric push rod 5 and a fixing frame 6. The fixing frame 6 is symmetrically connected to the left and right sides of the lower front side of the shell 1. The electric push rod 5 for controlling the lifting of the material frame 4 is installed on the fixing frame 6 by bolts. The two telescopic rods of the electric push rod 5 are respectively connected to the two sides of the material frame 4, and the electric push rod 5 is electrically connected to the controller 2.

[0028] When vacuum packaging the items, first place the bagged items on the discharge plate 8, and the damper 7 plays a buffering role to ensure that the items are placed stably. After placing them, the bag mouth is straightened and leveled. Then, the controller 2 is operated to start the two-way cylinder 9. The telescopic rod of the two-way cylinder 9 is shortened, driving the connecting plate 11 and the clamping plate 12 to move inward, and the clamping plate 12 clamps the left and right sides of the items. When the clamping plate 12 moves, the top plate 13 also moves accordingly, and finally contacts the top block 16, pushing the top block 16 and the rubber plate 14 to rotate, causing the torsion spring 15 to deform, and the rubber plate 14 will rotate 90 degrees to block the front of the material frame 4 to prevent the items from tipping forward. The limit plate 19 can limit the position of the bag mouth to ensure that the bag mouth does not tip backward. Next, the controller 2 is operated to start the motor 17. The output shaft of the motor 17 rotates to drive the rotating plate 18 to rotate, so that the rotating plate 18 tightens the bag mouth of the items. After the operation is completed, the motor 17 is turned off, which is convenient for the operator to put the bag mouth into the vacuum assembly 3 Then, the vacuum assembly 3 is started to vacuum-pack the items. After packaging is completed, the vacuum assembly 3 is closed. Then, the motor 17 is controlled to rotate in the reverse direction, driving the rotating plate 18 to reverse and reset. After resetting, the motor 17 automatically shuts down. Next, the telescopic rod of the two-way cylinder 9 is controlled to extend, driving the connecting plate 11 and the clamping plate 12 to move outward and reset. The clamping plate 12 no longer clamps the items. The top plate 13 moves and resets accordingly, breaking away from contact with the top block 16. The torsion spring 15 rebounds and resets, driving the rubber plate 14 and the top block 16 to reverse and reset. They no longer block the front of the material frame 4, and the packaged items can be unloaded. Other items can be vacuum-packed. When using this device, the height of the material frame 4 can be adjusted according to the height of the items to facilitate the alignment of the bag opening of the items with the vacuum assembly 3. In specific operation, the controller 2 is operated to start the electric push rod 5. When the telescopic rod of the electric push rod 5 is extended, the material frame 4 moves upward as a whole. When the telescopic rod is shortened, the material frame 4 moves downward as a whole. After adjustment, the electric push rod 5 is closed.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
