Many products all need the wrapping bag to pack, and taking tealeaves as an example, present tealeaves wrapping bag not only requires to be sealed the packing in the wrapping bag just can, still requires to improve packing efficiency, improves the impression of wrapping bag simultaneously.

The prior packaging method adopts manual packaging, and in recent years, a plurality of packaging machines for packaging tea leaves are developed, wherein the packaging machines are mainly shaped by a poking rod; specifically, stick to stretch into from the sack to waiting to seal from the wrapping bag, then will wait to seal wrapping bag 10 bottom and strut for wait to seal wrapping bag 10 bottom and form regular square structure, however this mode only can be waited to seal the packing bottom moulding, and is relatively poor to the moulding effect in 11 lateral walls of holding portion and top.

Further, some packaging machines can also perform shaping operation on the accommodating portion 11 by squeezing the bag body, however, it is inevitable to damage the contents, such as tea leaves, in the packaging bag when squeezing the bag body.

First, before describing the specific embodiment, it should be noted that the package to be sealed is a package which is not yet sealed, that is, the material can enter and exit through the mouth of the package 10 to be sealed. Further, the sizes of the receiving portion 11 and the empty portion 12 of the packaging bag 10 to be sealed are determined according to the actual amount of the material; namely, the height of the accommodating part 11 is determined according to the amount of the materials; when the bag is filled, the filling amount is set in advance according to the program, and the height of the accommodating portion 11 is determined. In the case of using the same packaging bag 10 to be sealed, the more the receptacle 11 is filled, the higher the height of the receptacle 11; the accommodating part 11 is arranged below the empty part 12, and the bag opening is arranged at the side of the empty part 12 far away from the accommodating part 11.

Referring to fig. 1 to 14, the present application discloses a packaging apparatus for packaging a packaging bag 10 to be sealed, wherein a lower portion of the packaging bag 10 to be sealed containing a material is a containing portion 11, an upper portion of the packaging bag 10 to be sealed is an empty portion 12, the packaging apparatus comprises:

the bag placing bin 20 is provided with a bag placing cavity 21 for containing the containing part 11 of the packaging bag 10 to be sealed, the bottom of the bag placing bin 20 is used for supporting the bottom of the packaging bag 10 to be sealed, and the upper part of the bag placing bin 20 is provided with an upper opening 22;

the sealing block 30 is positioned above the bag placing bin 20 and comprises a first sealing block 31 and a second sealing block 32, the first sealing block 31 and the second sealing block 32 are arranged in a reciprocating manner relatively in the horizontal direction, when the first sealing block 31 and the second sealing block 32 are folded in the horizontal direction, the vacant part 12 of the packaging bag 10 to be sealed is positioned between the first sealing block 31 and the second sealing block 32, the lower part of the sealing block 30 is in airtight fit with the upper opening 22 of the bag placing bin 20, the lower part of the sealing block 30 and the bag placing cavity 21 enclose a vacuum cavity 23, and an air suction opening is formed in the vacuum cavity 23 and is used for being connected with an air passage of a vacuum suction mechanism.

The bag placing bin is hollow, the top of the bag placing bin is of an open structure, the hollow part of the bag placing bin is a bag placing cavity 21, the top opening of the bag placing bin is an upper opening 22, the top opening of the receiving bin is used for allowing the packaging bag 10 to be sealed to enter and exit, and the bag placing cavity 21 is used for containing the packaging bag 10 to be sealed; that is, the packaging bag 10 to be sealed falls from the top opening of the receiving room into the bag placing cavity 21 of the receiving room.

The bag holding chamber 20 has a bag holding chamber 21 for holding the containing portion 11 of the package bag 10 to be sealed, and means that the height of the bag holding chamber 21 is higher than the height of the containing portion 11 of the package bag 10 to be sealed or the height of the bag holding chamber 21 is equal to the height of the containing portion 11 of the package bag 10 to be sealed.

It should be noted that the bag-containing cavity 21 and the expanded receiving portion 11 are adapted to each other; that is, in some embodiments, the expanded receptacle 11 can be placed right into the baghouse 21. In other embodiments, the size of the bag holding chamber 21 is larger than the size of the receptacle 11 after expansion, and the receptacle 11 and the sidewall of the bag holding chamber 21 form a gap around the receptacle 11.

The sealing block 30 is positioned above the bag placing bin 20, and the sealing block 30 is used for clamping the empty part 12 to prevent gas from entering and exiting from the opening of the packaging bag 10 to be sealed; the sealing block 30 comprises a first sealing block 31 and a second sealing block 32, the first sealing block 31 and the second sealing block 32 are arranged oppositely, specifically, the first sealing block 31 and the second sealing block 32 are arranged in a reciprocating manner in the horizontal direction, when the packaging bag 10 to be sealed does not fall into the bag storage bin 20, the first sealing block 31 and the second sealing block 32 are in a separated state, and a space is formed between the first sealing block 31 and the second sealing block 32, and the space is used for the packaging bag 10 to be sealed to pass through. The sealing block 30 is used for air-tight matching with the upper opening of the bag placing bin to prevent or reduce gas from flowing into the vacuum chamber from the joint part between the sealing block and the bag placing bin, and the first sealing block 31 and the second sealing block 32 are folded in the horizontal direction to prevent or reduce gas from flowing into the vacuum chamber from the gap between the first sealing block 31 and the second sealing block 32.

In some embodiments, the sealing block clamping empty part 12 prevents gas from entering and exiting from the opening of the packaging bag 10 to be sealed, and the packaging bag to be sealed is subjected to plasticity by utilizing the air expansion in the packaging bag to be sealed; in other embodiments, the sealing block does not clamp the empty part, but a neck opening for air to flow out from the empty part to the opening of the bag is formed in the empty part of the bag to be sealed between the first sealing block and the second sealing block, and the bag to be sealed is inflated while external air is sucked in through the neck opening when the vacuum chamber is vacuumized. The above two embodiments each have applicable scenarios. In the former, because the first sealing block and the second sealing block are tightly folded, gas can be prevented or reduced from flowing into the vacuum cavity from a gap between the first sealing block and the second sealing block to a greater extent, so that the vacuum cavity has better sealing property, and higher vacuum degree or faster vacuum pumping efficiency is easy to realize; the air pressure in the bag is close to the atmospheric pressure when the packaging bag to be sealed is expanded, so that the bag body is not easy to deform due to the action of the atmospheric pressure after the vacuum cavity is released from the vacuum state.

The bag placing bin 20 and the sealing block 30 can move in a mutually approaching or separating mode in the height direction, when the upper opening 22 of the bag placing bin 20 is flush with the lower edge of the sealing block 30, the bag placing bin 20 and the sealing block 30 stop moving in a mutually approaching mode, the first sealing block 31 and the second sealing block 32 approach each other to clamp the empty part 12 between the first sealing block 31 and the second sealing block 32, at the moment, the first sealing block 31 and the second sealing block 32 are in a folding state, and the sealing block 30 and the bag placing bin 20 are also in a folding state. Further, the process of the first sealing block 31 and the second sealing block 32 approaching each other is the process of enclosing the bag placing cavity 21 to form the vacuum cavity 23. In some embodiments, the bag magazine 20 and the sealing block 30 are stationary relative to each other in the height direction, and the upper opening 22 of the bag magazine 20 is flush with the lower edge of the sealing block 30.

In this application, closure refers to the condition of two objects approaching each other, or at the end of the process, when the two objects touch an intervening object (e.g., the package 10 to be sealed, etc.).

The hermetic sealing according to the present invention, which is described in the specification, may be a good hermetic sealing, or may allow a slight amount or a small amount of gas to leak, as long as the process requirement of evacuation is satisfied in the equipment or the process, for example, when a vacuum mechanism having a large evacuation amount is provided for the volume of the vacuum chamber 23, or the vacuum degree required for the process is not high, a slight amount or a small amount of gas leaks, and the vacuum degree required for the process is not affected, which is possible in the embodiment of the present specification. In order to improve the gas-tightness, sealing strips may be provided at the upper opening 22 and the lower opening 26 mentioned below, thereby preventing gas leakage; or sealing strips are arranged on the side wall of the first sealing block 31 opposite to the second sealing block 32 and/or the side wall of the second sealing block 32 opposite to the first sealing block 31, so as to prevent gas leakage.

When the sealing block 30 and the bag placing bin 20 are in a closed state, the bag placing cavity 21 is changed into a vacuum cavity 23, the vacuum cavity 23 is a sealed cavity, and the vacuum cavity 23 is provided with an extraction opening for gas to pass through; specifically, the air suction opening can be disposed on the sealing block 30 or the bag bin 20.

The evacuation port is connected to an evacuation mechanism for evacuating the gas in the vacuum chamber 23.

It should be noted that, when the evacuation mechanism evacuates the gas, the gas pressure in the vacuum chamber 23 is reduced, and at this time, the gas pressure in the accommodating portion 11 is greater than the gas pressure in the vacuum chamber 23, so that the accommodating portion 11 expands, the expanded accommodating portion 11 contacts with the wall of the vacuum chamber 23, and the wall of the vacuum chamber 23 limits and shapes the expanded accommodating portion 11, so that the package to be sealed forms a square shape; in some embodiments, the square shape is complementary to the vacuum chamber 23 side walls. In other embodiments, different shaped packages may be used in conjunction with a vacuum chamber adapted to accommodate the package in order to plastically form the package shape into the desired finished shape. Of course, as mentioned in the previous part of the present description, in some embodiments, the size of the bag cavity 21 may be larger than that of the expanded receiving portion 11, and the expanded receiving portion 11 does not contact with the wall of the vacuum cavity 23, but is only plasticized by the shape and structure of the packaging bag to be sealed.

Referring to fig. 15, in some embodiments, when the bag to be sealed is inflated, the shoulder of the receptacle abuts against the lower portion of the sealing block, and the shoulder of the receptacle is plasticized to obtain a more regular bag. In some embodiments, the height of the expanded and shaped receptacle 11 is the same as the distance between the seal block 30 and the bottom of the vacuum chamber 23.

In some embodiments, a lifting member 100 capable of moving up and down is disposed in the bag placing cavity, and the lifting member 100 is used for supporting the bottom of the packaging bag to be sealed. Specifically, when the amount of tea leaves in the bag to be sealed is small (i.e., the height of the accommodating portion is low), the lifting member 100 is closer to the upper opening; similarly, when the amount of tea leaves in the bag to be sealed is large (i.e. the height of the accommodating portion is large), the distance from the lifting member 100 to the upper opening is long.

Further, in some embodiments, the lifter 100 and the bag cavity are adapted to each other, i.e., the cross-section of the bag cavity is the same size as the cross-section of the lifter 100. Or in some embodiments the elevator 100 only serves to hold the package to be sealed.

When the lifting piece 100 and the bag placing cavity are matched with each other, the lifting piece 100 and the vacuum frame form the bag placing cavity, and the pumping hole is always placed above the lifting piece 100.

In some embodiments, referring to fig. 17, the lifting member may be a plate-shaped structure or an L-shaped structure disposed opposite to each other, and both of the lifting member and the L-shaped structure are used for supporting the packaging bag to be sealed.

According to the technical scheme, the bag placing bin 20 can support the packaging bag 10 to be sealed through the arrangement of the bag placing bin 20; the vacuum chamber 23 is formed by enclosing the lower part of the sealing block 30 and the bag placing chamber 21 by the arrangement of the first sealing block 31 and the second sealing block 32 which reciprocate relatively in the horizontal direction. The vacuumizing mechanism is used for vacuumizing the gas in the vacuum cavity 23 to finish the vacuum shaping operation of the packaging bag 10 to be sealed; furthermore, the packaging equipment only needs to carry out vacuum operation on the part needing to be shaped, so that the energy consumption is reduced, and the vacuum shaping efficiency is improved. Meanwhile, the damage to the content during shaping is avoided.

In the packaging apparatus of the embodiment, a sealing block is further included, and in some embodiments, the sealing block is integrally provided with the sealing block 30. That is, the sealing block 30 functions as a sealing block, and sealing operation can be performed when the first sealing block 31 and the second sealing block 32 are in a closed state.

In some embodiments, the sealing block 30 itself is a sealing block (i.e. the sealing block and the sealing block are integrally disposed), when the vacuum-pumping operation is performed, the sealing block 30 clamps the packaging bag 10 to be sealed, and when the vacuum-pumping operation is completed, the sealing block 30 starts a sealing function (at this time, the sealing block is a heat-sealing block), and performs a sealing operation on the packaging bag to be sealed.

Referring to fig. 1 to 14, in order to facilitate separation of the formed packaging bag from the packaging apparatus, the bag storage bin 20 of the present embodiment includes:

The vacuum frame 25 is a square tubular structure with two open ends and a hollow middle part, specifically, the upper opening 22 of the vacuum frame 25 is the upper opening 22 of the bag placing bin 20, the lower opening 26 of the vacuum frame 25 is arranged right opposite to the upper opening 22, and the lower opening 26 is used for air-tight matching with the bag receiving seat. When the lower opening 26 and the bag receiving seat 24 are in a closed state, the hollow portion in the vacuum frame 25 becomes the bag placing cavity 21.

In other embodiments, when the lifting member 100 and the bag placing cavity are matched with each other, the lifting member 100 extends into the vacuum frame from the lower opening, and the lifting member 100 is in airtight fit with the vacuum frame, at this time, the cavity in the vacuum chamber above the lifting member 100 is the bag placing cavity.

The vacuum frame 25 is then moved upward together with the bag holder 24 until the upper opening 22 is flush with the lower edge of the sealing block 30.

In some embodiments, the bag holder 24 is drivingly connected to the fourth power source, and the vacuum frame 25 is drivingly connected to the vacuum frame power source, i.e., the bag holder 24 and the vacuum frame 25 are both independently movable.

When the bag holder 24 moves upward and closes with the vacuum frame 25, the lower opening 26 and the bag holder 24 are in airtight fit.

After shaping is finished, the bag contact base 24 moves downwards, at the moment, the vacuum frame 25 and the bag contact base 24 move downwards together, and after the vacuum frame 25 is contacted with the limiting piece 40, the limiting piece 40 blocks the vacuum frame 25 to make the vacuum frame 25 still; and then the subsequent bag holder 24 continues to move downward. Referring to fig. 1, 2, 4, 13 and 14, when the sealing block 30 is a heat sealing block, the sealing block 30 cannot be cooled in time during the vacuum shaping and sealing process, so that the sealing block 30 will leave a clamp mark on the package 10 to be sealed, and in order to prevent the package 10 to be sealed from leaving a mark, some embodiments further include: a cover block 50, said cover block 50 comprising a first cover block 51 and a second cover block 52; the sealing block 50 is used for sealing the packaging bag to be sealed;

The driving relationship of the sealing block 50 to the second power source 53 is similar to the driving relationship of the sealing block 30 to the first power source, and will not be described again here.

In actual use, the first sealing block 31 and the second sealing block 32 are closed in the horizontal direction under the driving of the first power source, and after the vacuum shaping operation is performed, the second power source 53 drives the first sealing block 51 and the second sealing block 52 to be closed and sealed in the horizontal direction.
