[0074] In some embodiments, the packing device further comprises a first guide rail 114 mounted on the first rack 111, the first guide rail 114 is arranged to extend in the first direction; the lifting body 112 is connected with the first guide rail 114 in sliding fit; and a first transmission assembly 115 is mounted on the first rack 111, used to drive the lifting body 112 to move relative to the first rack 111 in the first direction. Specifically, one side of the lifting body 112 can be provided with a first sliding block, the first sliding block is connected with the first guide rail 114 in sliding fit, so as to provide guidance when the lifting body 112 moves up and down, so that the sliding of the lifting body 112 is more stable and reliable; the first transmission assembly 115 can include a lead screw, a nut matched with the lead screw, and a driving motor; wherein the lead screw is arranged in parallel with the first guide rail 114, and the nut is connected and fixed with the side surface of the lifting body 112; the output shaft of the driving motor is connected with the lead screw to drive the lead screw to rotate, thereby driving the lifting body 112 to move up and down along the first guide rail 114.

[0075] In some embodiments, the grabbing part comprises a suction cup rack 116 connected with the bottom end of the lifting body 112, a plurality of negative pressure suction cups 1161 are arranged on the suction cup rack 116; the negative pressure suction cups 1161 are located on the side facing the hopper 113; the suction cup rack 116 is arranged to move relative to the lifting body 112 in the first direction, so that the negative pressure suction cups 1161 contact and adsorb the packaging bag in the hopper 113. Specifically, the lifting body 112 moves downward and approaches the hopper 113, under the action of negative pressure, the negative pressure suction cups 1161 tightly adsorb the packaging bag, completing the grabbing action. The packaging bag is made of relatively thin and light material, and the negative pressure suction cups 1161 are more reliable in grabbing the packaging bag. When the lifting body 112 moves upward to a predetermined height, the output platform 121 moves backward to return to the upper side of the hopper 113, and then the lifting body 112 moves downward to approach the output platform 121, the vacuum system opens the positive pressure, and the negative pressure suction cups 1161 place the packaging bag. When the negative pressure suction cups 1161 reach the height of the output platform 121, the vacuum system quickly switches mode from negative pressure to positive pressure or simply releases the vacuum, reducing the adsorption force between the negative pressure suction cups 1161 and the packaging bag; this conversion enables the packaging bag to be placed on the output platform 121 smoothly and accurately, avoiding the packaging bag from falling or being damaged due to sudden release.

[0076] In the example embodiment, as shown in FIG. 18, the packaging device further comprises a vacuum system for providing negative pressure for the suction cup 1161 to suck the packaging bag and providing positive pressure for the suction cup 1161 to place the packaging bag; the vacuum system comprises a vacuum pump 1181, a first electromagnetic valve 1182 and a second electromagnetic valve 1183, the air inlet 11811 of the vacuum pump, the first electromagnetic valve 1182 and the suction cup 1161 are sequentially communicated by pipes to suck out the air at the suction cup 1161 so that the suction cup 1161 forms a negative pressure environment; the air outlet 11812 of the vacuum pump, the second electromagnetic valve 1183 and the suction cup 1161 are sequentially communicated by pipes to release positive pressure air to the suction cup 1161; wherein the first electromagnetic valve 1182, the second electromagnetic valve 1183 and the suction cup 1161 are communicated by a three-way piece; the first electromagnetic valve 1182 and the second electromagnetic valve 1183 are both two-position three-way electromagnetic valves in a normally closed state; when the first electromagnetic valve 1182 is powered on, the air inlet 11811 of the vacuum pump, the first electromagnetic valve and the suction cup 1161 are sequentially communicated by pipes to suck out the air at the suction cup 1161 so that the suction cup 1161 forms a negative pressure environment; under the action of negative pressure, the suction cup 1161 can tightly adsorb the packaging bag to complete the grabbing action. When the first electromagnetic valve loses power and the second electromagnetic valve 1183 is powered on, the air outlet 11812 of the vacuum pump, the second electromagnetic valve and the suction cup 1161 are sequentially communicated by pipes to release positive pressure air to the suction cup 1161; in this way, the vacuum system quickly switches mode from negative pressure to positive pressure, which can weaken the adsorption force between the suction cup 1161 and the packaging bag. A filter 1184 can be arranged between the three-way piece and the suction cup 1161 to remove particulate matter and impurities, which can improve the vacuum degree and prolong the service life of the equipment.

[0077] In some embodiments, the packaging device further comprises a guide assembly 117 comprising a guide shaft, a spring and a guide sleeve; the guide sleeve is arranged on the lifting main body 112, one end of the guide shaft is fixedly connected with the suction cup holder 116, the spring is sleeved on the guide shaft, the other end of the guide shaft passes through the guide sleeve, and the guide shaft and the guide sleeve are slidably connected; wherein the spring is located between the suction cup holder 116 and the lifting main body 112. Specifically, the guide assembly 117 can be arranged near the four right angles of the lifting main body 112; when the lifting main body 112 drives the suction cup holder 116 to move downward, the spring on the suction cup holder 116 will be compressed at the moment when the suction cup 1161 contacts the packaging bag; this design not only buffers the impact at the moment of contact, but also provides guidance through the sliding fit structure of the guide shaft and the guide sleeve to ensure that the suction cup 1161 can rise vertically and stably.

[0078] In some embodiments, the packing device further comprises a detection mechanism, which comprises a sensor and a fixed plate; the sensor is installed on the lifting body 112, and the sensor is located on the side of the lifting body 112 away from the suction plate frame 116; the other end of the guide shaft passes through the guide sleeve and is connected and fixed with the fixed plate; when the suction plate 1161 contacts the packaging bag in the hopper 113, the spring is compressed, the fixed plate rises relative to the lifting body 112 and is inducted by the sensor. Specifically, the sensor can be selected as a paper suction sensor; the driving motor is started to drive the lead screw to rotate, thereby driving the lifting body 112 to move downward along the first guide rail 114, when the suction plate 1161 contacts the packaging bag, the spring on the suction plate frame 116 will be compressed; the structure of the guide shaft and the guide sleeve sliding fit provides guidance, and the guide shaft lifts the fixed plate upward. When the spring is compressed by a certain stroke, the fixed plate rises to a certain height, which can trigger the paper suction sensor, the signal on the paper suction sensor is transmitted, that is, it is detected that the suction plate 1161 is correctly positioned and contacts the packaging bag, the driving motor stops running, and the downward movement of the lifting body 112 stops; the vacuum system opens the negative pressure, and the suction plate 1161 grabs the packaging bag, so that the grabbing of a single packaging bag can be accurately controlled. When the lifting body 112 moves upward by a certain distance, the spring resets, the suction plate frame 116 falls downward, and the fixed plate is driven downward by the guide shaft, and the fixed plate falls back on the lifting body 112.
