It should be understood that the similar features in the present invention are only distinguished by different prefixes, so in the present embodiment, the feature names without the prefixes are used to represent the combination of the similar features, such as "suction cup" (without other prefixes) to represent left and right suction cups; or the combination of similar features in this category is represented by feature names with partial prefixes, such as "lower left holding strip" and "lower right holding strip" and "upper left holding strip" and "upper right holding strip".

Referring to fig. 1 to 11, an automatic packaging machine according to an embodiment of the present invention includes a frame 100, a lower left clip strip 210, a lower right clip strip 220, a first driving mechanism 300, a second driving mechanism 400, an upper left clip strip 510, an upper right clip strip 520, a third driving mechanism 600, and a charging mechanism 1000, the lower left clip strip 210 is used to be relatively close to the lower right clip strip 220 to clamp a bag 1400, the first driving mechanism 300 is disposed on the frame 100, the first driving mechanism 300 is connected to the lower left clip strip 210 and/or the lower right clip strip 220, the first driving mechanism 300 is used to drive the lower left clip strip 210 to be relatively close to or relatively far from the lower right clip strip 220, the second driving mechanism 400 is disposed on the frame 100, the second driving mechanism 400 is connected to the lower left clip strip 210 and the lower right clip strip 220, the second driving mechanism 400 is used to drive the lower left clip strip 210 and the lower right clip strip 220 to move forward or backward together, the upper left clip strip 510 is used to be relatively close to the upper right clip strip 520, thereby gripping the bag 1400, a third drive mechanism 600 is provided on the frame 100, the third drive mechanism 600 is connected to the upper left gripping strip 510 and/or the upper right gripping strip 520, the third drive mechanism 600 is used to drive the upper left gripping strip 510 relatively closer to or relatively farther from the upper right gripping strip 520, a charging mechanism 1000 is provided on the frame 100, and the charging mechanism 1000 is used to charge the bag 1400.

It is understood that one of the upper left and right clamping bars 510, 520 may be fixed to the frame 100 or be a part of the frame 100. It should be understood that the upper left and right clamping strips 510, 520 may directly clamp the bag 1400, or the bag 1400 may be clamped by extensions of the upper left and right clamping strips 510, 520 or additional members (upper left and right clamping fingers); the same applies to the lower left holding strip 210 and the lower right holding strip 220.

Referring to fig. 2 and 3, the bag transporting principle of the automatic packing machine is briefly described as follows:

first, the second driving mechanism 400 drives the lower left holding strip 210 and the lower right holding strip 220 to move forward together (at this time, the lower left holding strip 210 and the lower right holding strip 220 are in a state of being away from each other, and the lower left holding strip 210 and the lower right holding strip 220 do not or cannot hold the bag 1400), until the lower left holding strip 210 and the lower right holding strip 220 move forward and backward together to the foremost end (the left holding strip and the lower right holding strip 220 can move forward and backward together, but the moving range of the left holding strip and the lower right holding strip 220 is limited, i.e., the left holding strip and the lower right holding strip cannot move forward and backward all the time, so that when the left holding strip and the lower right holding strip 220 move forward and the foremost end, the forward movement cannot be continued, and the backward movement can be started until the backward movement of the left holding strip and the last end can not continue, and the forward movement can be started again, so that the cycle is repeated);

in a second step, the first driving mechanism 300 drives the lower left clamping bar 210 and the lower right clamping bar 220 to be relatively close to each other so as to clamp the bag 1400 (before the bag 1400 is clamped by the upper left clamping bar 510 and the upper right clamping bar 520 or by other things such as the bag taking mechanism 700), and the third driving mechanism 600 drives the upper left clamping bar 510 and the upper right clamping bar 520 to be relatively far away (or other things such as the bag taking mechanism 700 and the hand of the worker release the bag 1400), so as to release the bag 1400;

third, the second driving mechanism 400 drives the lower left holding strip 210 and the lower right holding strip 220 (with the bag 1400) to move backward together to the rearmost end, and then the third driving mechanism 600 drives the upper left holding strip 510 and the upper right holding strip 520 to relatively approach each other (or the bag 1400 is fixed by the bag holding mechanism 800, the bag sealing mechanism 1200, and other things), so as to hold the bag 1400; recycled to the first step.

Between the third step and the first step (i.e., with the upper left and right clamping strips 510, 520 clamping the bag 1400, the lower left and right clamping strips 210, 220 moving forward), the bag 1400 can be filled by the filling mechanism 1000.

Referring to fig. 5, 6 and 10, in some embodiments of the present invention, the bag collecting mechanism 800 is further included, the bag collecting mechanism 800 is connected to the upper left holding strip 510 and the upper right holding strip 520, and the bag collecting mechanism 800 is used to enable two sides of the opening of the bag 1400 to approach each other.

When the upper left holding strip 510 and the upper right holding strip 520 are relatively close to each other, the bag 1400 is held by the bag holding mechanism 800 arranged on the upper left holding strip 510 and the upper right holding strip 520, and the two sides of the opening of the bag 1400 are close to each other by the bag holding mechanism 800, so that the opening of the bag 1400 is easy to open and the opening degree can be larger.

Referring to fig. 5, 6 and 10, in some embodiments of the present invention, the bag closing mechanism 800 comprises a first left bag closing sliding seat 810, a second left bag closing sliding seat 820, a first right bag closing sliding seat 830, a second right bag closing sliding seat 840 and a bag closing transmission assembly 850, the first left bag closing sliding seat 810 is provided with a first upper left clamping finger 811, the second left bag closing sliding seat 820 is provided with a second upper left clamping finger 821, the first right bag closing sliding seat 830 is provided with a first upper right clamping finger 831, the second right bag closing sliding seat 840 is provided with a second upper right clamping finger 841, the first left bag closing sliding seat 810, the second left bag closing sliding seat 820 are slidably connected with the upper left clamping strip 510, the first right bag closing sliding seat 830, the second right bag closing sliding seat 840 are slidably connected with the upper right clamping strip 520, the bag closing transmission assembly 850 is connected with the first left bag closing sliding seat 810, the second left bag closing seat 820, the first right bag closing sliding seat 830 and the second right bag closing sliding seat 840, the first upper left clamping finger 811 is used for being relatively close to the first upper right clamping finger 831 so as to clamp one side of the opening of the bag 1400, the second upper left clamping finger 821 is used for being relatively close to the second upper right clamping finger 841 so as to clamp the other side of the opening of the bag 1400, and the bag-closing transmission assembly 850 is used for driving the first left bag-closing sliding seat 810 and the second left bag-closing sliding seat 820 to be close to each other, and the first right bag-closing sliding seat 830 and the second right bag-closing sliding seat 840 to be close to each other so as to enable two sides of the opening of the bag 1400 to be close to each other.

It should be understood that the upper clamping fingers 530 may be directly slidably connected to the upper clamping strip, and the bag closing actuator assembly 850 drives the upper clamping fingers 530 to slide on the upper clamping strip. It should be understood that, in the description of the present invention, the first upper left clamping finger 811 and the first upper right clamping finger 831 may be collectively referred to as a first pair of upper clamping fingers 530, and the other same principle (for example, a second pair of upper clamping fingers 530, a fifth pair of lower clamping fingers 230, etc.). The upper left holding strip 510 is provided with a first left bag gathering sliding seat 810 and a second left bag gathering sliding seat 820, so that the upper left holding strip 510 can carry the first left bag gathering sliding seat 810 (provided with a first upper left clamping finger 811) and the second left bag gathering sliding seat 820 (provided with a second upper left clamping finger 821) to move together along the left-right direction (relatively close to or far away from the upper right holding strip 520); the first left bag gathering sliding seat 810 and the second left bag gathering sliding seat 820 are connected with the upper left holding strip 510 in a sliding manner, so that the first left bag gathering sliding seat 810 and the second left bag gathering sliding seat 820 can move back and forth along the upper left holding strip 510, namely the first left bag gathering sliding seat 810 (or the first upper left clamping finger 811) and the second left bag gathering sliding seat 820 (or the second upper left clamping finger 821) can be close to or far away from each other; the upper right holding strip 520, the first right bag holding sliding seat 830 and the second right bag holding sliding seat 840 are similar. It should be understood that the clamping fingers can be slidably connected to the clamping strip (or the sliding seat) (the clamping fingers are similar to the piston rod) to facilitate clamping the bag 1400, and the clamping fingers can return to the clamping finger position and also ensure clamping the bag 1400 by setting a spring or an inflation assembly or the like to make the clamping fingers have a tendency to move away from the clamping strip (or the sliding seat) or a practical action.

The bag gathering principle of the automatic packaging machine is briefly described as follows:

first, the upper left clamping strip 510 and the upper right clamping strip 520 approach each other relatively, so as to drive the first left bag-closing sliding seat 810 (on which the first upper left clamping finger 811 is disposed) and the first right bag-closing sliding seat 830 (on which the first upper right clamping finger 831 is disposed) to approach each other, and at the same time, drive the second left bag-closing sliding seat 820 (on which the second upper left clamping finger 821 is disposed) and the second right bag-closing sliding seat 840 (on which the second upper right clamping finger 841 is disposed) to approach each other, so that the first upper left clamping finger 811 and the first upper right clamping finger 831 cooperate to clamp one side of the opening of the bag 1400, and the second upper left clamping finger 821 and the second upper right clamping finger 841 cooperate to clamp the other side of the opening of the bag 1400 (or the first pair of upper clamping fingers 530 clamps one side of the opening of the bag 1400, and the second pair of upper clamping fingers 530 clamps the other side of the opening of the bag 1400); (with the lower left clip strip 210 and the lower right clip strip 220 relatively far apart, freeing the bag 1400).

In the second step, the first left bag-closing sliding seat 810 and the second left bag-closing sliding seat 820 approach each other, and the first right bag-closing sliding seat 830 and the second right bag-closing sliding seat 840 approach each other (or the first pair of upper fingers 530 and the second pair of upper fingers 530 approach each other), so as to drive the two sides of the opening of the bag 1400 to approach each other.

Referring to fig. 1 and 7, in some embodiments of the present invention, the present invention further includes a bag opening mechanism 900, the bag opening mechanism 900 is disposed on the frame 100, and the bag opening mechanism 900 is used for opening the bag 1400.

After the bag is closed (or the bag 1400 is clamped by the upper clamping strip), the bag opening mechanism 900 opens the open end of the bag 1400, so that the filling mechanism 1000 can fill the bag 1400 through the opening of the bag 1400. It should be appreciated that in this embodiment, after the bag gathering step is completed (the first pair of upper clamping fingers 530 and the second pair of upper clamping fingers 530 clamp the bag 1400 and have been brought closer together), the bag opening step is performed again, so that the bag 1400 is larger in opening and easier to fill.

Referring to fig. 1 and 7, in some embodiments of the present invention, the bag opening mechanism 900 includes a left suction cup 910 and a right suction cup 920, and at least one of the left suction cup 910 and the right suction cup 920 is slidably connected to the frame 100.

The suction cup is used for sucking the front side or the back side of the bag 1400, and after the suction cup sucks one side of the bag 1400, the suction cup moves in the direction away from the bag 1400, so that the one side of the bag 1400 is driven to be away from the other side of the bag 1400, and the opening of the bag 1400 is opened. It should be understood that the bag opening mechanism 900 may further include a suction assembly connecting the left suction cup 910 and the right suction cup 920 for allowing the left suction cup 910 to suck one side of the bag 1400 and the right suction cup 920 to suck the other side of the bag 1400.

Referring to fig. 1 and 7, in some embodiments of the present invention, the bag opening mechanism 900 further includes a left bag opening sliding seat 930, a right bag opening sliding seat 940 and a bag opening transmission assembly 950, the rack 100 is provided with the bag opening sliding rod 110, the left suction cup 910 is disposed on the left bag opening sliding seat 930, the left bag opening sliding seat 930 and the bag opening sliding rod 110 are slidably connected, the right suction cup 920 is disposed on the right bag opening sliding seat 940, the right bag opening sliding seat 940 and the bag opening sliding rod 110 are slidably connected, the bag opening transmission assembly 950 is connected with the left bag opening sliding seat 930 and/or the right bag opening sliding seat 940, and the bag opening transmission assembly 950 is used for driving the left bag opening sliding seat 930 to be relatively close to or relatively far away from the right bag opening sliding seat 940.

The bag opening principle of the automatic packaging machine is briefly described as follows: firstly, the suction assembly sucks air to enable the suction cups to suck the bag 1400, and then the left bag opening sliding seat 930 and the right bag opening sliding seat 940 are relatively far away to drive the left suction cup 910 and the right suction cup 920 to be relatively far away, so that the opening of the bag 1400 is opened; second, the suction assembly no longer sucks air, and the suction cup releases the bag 1400; third, the lower left gripper bar 210 and the lower right gripper bar 220 are relatively close to each other, the third pair of lower gripper fingers 230 grip one side of the bag 1400, the fourth pair of lower gripper fingers 230 grip the other side of the bag 1400, the upper left gripper bar 510 and the upper right gripper bar 520 are relatively far away, the first pair of upper gripper fingers 530 and the second pair of upper gripper fingers 530 are relatively far away, the bag 1400 is released, and the lower left gripper bar 210 and the lower right gripper bar 220 grip and convey the bag 1400 to the next station.

Referring to fig. 1 and 8, in some embodiments of the present invention, the charging mechanism 1000 includes a storage hopper 1010, a discharging movable nozzle 1020 and a charging control cylinder 1030, the storage hopper 1010 is connected with the frame 100, the discharging movable nozzle 1020 is disposed at the lower opening of the storage hopper 1010, the charging control cylinder 1030 is in transmission connection with the discharging movable nozzle 1020, and the charging control cylinder 1030 is used for driving the discharging movable nozzle 1020 to open or close.
