Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and in particular to a vacuum packaging machine with a shaping function. Background Art

[0002] Vacuum packaging equipment is a packaging method that puts the product into a sealed packaging container and extracts the air inside the package to achieve a certain degree of vacuum inside, thereby inhibiting the growth and reproduction of microorganisms and extending the shelf life of the product. Vacuum packaging equipment is particularly widely used in food processing companies.

[0003] Although the existing vacuum packaging machines are highly intelligent and easy to operate, their operating and maintenance costs are relatively high. Once the equipment fails, if the company cannot solve the problem in time, the production efficiency will be greatly affected. In response to the above situation, some companies have carried out targeted equipment manufacturing. Although the equipment has been greatly simplified and can also complete a good quality seal, it will not significantly reduce production efficiency. However, during the debugging stage, it was found that since the plastic bags are placed in piles on the equipment, the items enter the plastic bags, and the plastic bags need to be placed in the correct position. Once the angle of the plastic bag changes, the robot cannot open the plastic bag well, which affects the efficiency of putting food into the plastic bag. After the plastic bag is sealed, it needs to be transferred away. During the transfer process, it is easy to cause the angle of the lower plastic bag to deviate.

[0004] Therefore, a new vacuum packaging equipment is needed urgently. Utility Model Content

[0051] The flattening plate 31 is slidably disposed on the support 1 in the vertical direction;

[0052] The driving member is arranged on the support 1 and has a driving end that reciprocates in the vertical direction. The flattening plate 31 is located on the driving end. The flattening plate 31 cooperates with the pressing plate 27 by means of the reciprocating movement of the driving end to flatten the plastic bag.

[0053] In this embodiment, the simple vacuum packaging equipment includes a support 1, a packaging component 2 and a flattening component 3. The packaging component 2 and the flattening component 3 are both arranged on the support 1. The packaging component 2 is used to seal the packaging bag, and the flattening component 3 is used to flatten the packaging bag that has not been sealed after the sealed packaging bag is taken away. Since the packaging bags are stacked, each time the packaging bag is filled with items and sealed, the packaging bag needs to be taken away, and then the remaining packaging bags need to be flattened, otherwise it will lead to a decrease in packaging efficiency. The packaging component 2 includes a pressing plate 27, and the leveling component 3 includes a leveling plate 31 and a driving member. The leveling plate 31 is arranged on the driving end of the driving member, and the leveling plate 31 is located below the pressing plate 27. A groove is opened on the leveling plate 31, and the packaging bag is placed in the groove. When the sealed packaging bag is taken away, the leveling plate 31 moves in the vertical direction to shake the piled packaging bags, thereby leveling the packaging bags, making it convenient to put the items into the packaging bags, and improving the packaging efficiency.

[0054] It should be specially noted that the simple vacuum packaging equipment provided by the utility model needs to be used in conjunction with a robot or a human being, and the robot or the human being puts the articles into the packaging bag and then performs vacuuming and sealing operations.

[0055] Further, if Figure 2 As shown, this embodiment proposes that the driving member includes:

[0056] The transmission shaft 32 is arranged inside the support 1, and the transmission shaft 32 is rotatably arranged on the support 1;

[0057] The cam 33 is sleeved on the transmission shaft 32 and rotates synchronously with the transmission shaft 32;

[0058] The transmission plate 34 is slidably disposed inside the support 1 and is always in contact with the outer edge of the cam 33;

[0059] The transmission rod 35 has a first end that passes through the interior of the support 1 and is connected to the transmission plate 34 , and a second end that passes through the exterior of the support 1 and is connected to the leveling plate 31 .

The transmission shaft 32 is rotatably arranged inside the support 1, and the support 1 has an inner cavity, thereby forming a structural form of the inside and outside of the support 1, and the transmission shaft 32 is rotated by an external power mechanism. The cam 33 is arranged on the transmission shaft 32, and the cam 33 can rotate synchronously with the transmission shaft 32. The transmission plate 34 is slidably arranged inside the support 1. One end of the transmission rod 35 is connected to the transmission plate 34, and the other end is connected to the flat plate 31. The transmission rod 35 is arranged through the support 1, and under the action of gravity, the transmission plate 34 always keeps in contact with the outer edge of the cam 33. Under the full rotation of the cam 33, the transmission plate 34 and the flat plate 31 will reciprocate in the vertical direction. The transmission rod 35 not only plays the role of transmitting power, but also cooperates with the support 1 to play a guiding role, thereby improving the stability of the flat plate 31 during the movement.

The support plate 21 is L-shaped or concave-shaped, the push piece 22 is arranged on the support plate 21 and has a push top end, the pressing plate 27 is arranged on the push top end, the pressing plate 27 can achieve reciprocating movement in the vertical direction with the help of the push piece 22, the suction nozzle 23 is arranged on the pressing plate 27 and is used to vacuum the packaging bag, the suction nozzle 23 is connected to the vacuum pump through an air pipe, the hot melt strip 24 is arranged on the pressing plate 27 and heat-seals the packaging bag, and the hot melt strip 24 is connected to the heating power supply through an electric wire. After the pressing plate 27 presses the packaging bag, the suction nozzle 23 extracts the air in the packaging bag, and then the hot melt strip 24 is energized, and after energization, the packaging bag can be heat-sealed.

[0078] Further, if Figure 3 As shown, this embodiment proposes that the packaging assembly 2 also includes a guide member, and the guide member includes:

[0079] A guide protrusion 25, which is disposed on the support plate 21 and has a guide hole;

[0080] The second guide rod 26 is inserted into the guide hole, and the end of the second guide rod 26 is connected to the pressing plate 27 .
