[0027] As Figures 1 to 7 shown, the present application claims a kind of food automatic bag discharging opening bagging mechanism, mainly for the bag that is folded into flat is opened;Specifically, including bag discharging structure 1, bag discharging structure 1 below is provided with opening structure 2, for the bag that is sent down from bag discharging structure 1 opening is opened;Opening structure 2 includes oppositely arranged left bag opening suction cup 201 and right bag opening suction cup 202, left bag opening suction cup 201 and right bag opening suction cup 202 are connected with vacuum pump, so as to have adsorption force.

[0028] The bag-out structure 1 comprises a bag-out bin 101, which is in a curved downward extending shape, so that the bag is transmitted along the conveying channel of the bag-out bin 101 to between the left bag opening suction plate 201 and the right bag opening suction plate 202; and further comprises a lifting platform 27, which is located below the bag opening structure 2; when the bag falls from the bag-out bin 101, the lifting platform 27 can be raised to have a supporting effect on the bag, so that the opening at the upper end of the bag is just between the left bag opening suction plate 201 and the right bag opening suction plate 202, the left bag opening suction plate 201 and the right bag opening suction plate 202 are close to each other and generate suction force, and the two ends of the bag are sucked, and then the left bag opening suction plate 201 and the right bag opening suction plate 202 move away from each other in a back direction, thereby opening the bag opening of the bag.

[0029] Since the use of suction opening alone may cause unstable suction force and abnormal conditions, the mechanism further comprises a mechanical clamping structure, specifically: a bag clamping anti-falling structure 3 is arranged on the left bag opening suction plate 201 and the right bag opening suction plate 202; the bag clamping anti-falling structure 3 comprises a first motor 301, a motor shaft of the first motor 301 is connected with a clamp 302, the first motor 301 drives the clamp 302 to rotate, and the clamp 302 is arranged on the left bag opening suction plate 201 and the right bag opening suction plate 202 Figure 5 and Figure 7 As can be seen, the clamping surface of the clamp 302 is directed to the suction surface of the corresponding left bag opening suction plate 201 and right bag opening suction plate 202, and when the left bag opening suction plate 201 and the right bag opening suction plate 202 are adsorbed on both sides of the bag opening, the first motor 301 drives the clamp 302 to rotate, so that the clamping surface of the clamp 302 moves close to the suction surface of the left bag opening suction plate 201 and the right bag opening suction plate 202 to press the edge of the bag, thereby achieving the anti-falling effect; when the bag needs to be loosened, the left bag opening suction plate 201 and the right bag opening suction plate 202 are released from adsorption, and the first motor 301 drives the clamp 302 to rotate in the opposite direction, so that the clamping surface of the clamp 302 moves away from the suction surface of the left bag opening suction plate 201 and the right bag opening suction plate 202 to release the edge of the bag; through the above structure, the stability of the bag opening fixation is enhanced.

[0030] In combination with Figure 2Look, still including bag storage frame 102, out bag warehouse 101 is connected on bag storage frame 102, and the lifting movable setting of bag storage frame 102 is provided with the supporting plate 103 for placing bag, and the bag is stacked on the supporting plate 103 and is sequentially discharged;The lower portion of supporting plate 103 is connected with guide rod 104, and the bottom of bag storage frame 102 is provided with guide rod seat 105, and guide rod 104 is slidably connected on guide rod seat 105;The first spring 106 is sleeved on guide rod 104, and the first spring 106 is abutted between guide rod 104 and bag storage frame 102.The effect of the structure is that the first spring 106 has a continuous thrust on guide rod 104, that is, a continuous upward thrust on supporting plate 103, so that when the highest bag is taken away, the next bag will be pushed up and discharged in turn;

[0031] The first receiving roller 4 and the second receiving roller 5 are arranged at the entrance of the bag outlet bin 101 and are driven to rotate by a motor component, and the first receiving roller 4 and the second receiving roller 5 rotate towards each other to roll the bag into the bag outlet bin 101; the bag storage frame 102 is provided with a suction bag separator 6 above, which is used to suction the bag on the bag storage frame 102 to drive it between the first receiving roller 4 and the second receiving roller 5; the suction bag separator 6 comprises a bag separator fixing seat 601 fixedly installed on the bag storage frame 102, a bag conveying displacement swing arm 602 rotatably connected to the bag separator fixing seat 601, a vacuum manifold pipe 603 connected to the bag conveying displacement swing arm 602, a suction disc 604 communicatively arranged on the vacuum manifold pipe 603, a vacuum pipe 605 connected to the vacuum manifold pipe 603, and a vacuum generator 606 connected to the vacuum pipe 605; the bag separator fixing seat 601 is further connected with an electric push rod 607, and the movable end of the electric push rod 607 is connected to the middle part of the bag conveying displacement swing arm 602 to drive the bag conveying displacement swing arm 602 to swing. Therefore, the working mode is that the vacuum generator 606 is started to make the vacuum manifold pipe 603 and the suction disc 604 have a vacuum suction force, and in the process of suctioning the bag, the electric push rod 607 pushes the bag conveying displacement swing arm 602 to swing forward, so as to convey the bags one by one to the first receiving roller 4 and the second receiving roller 5 to be rolled in.

[0033] In the present embodiment, a second mounting seat 22 is also included, a third mounting seat 23 is transversely slidably arranged on the second mounting seat 22, and the third mounting seat 23 is provided with a gripper component 24 for grabbing food; the gripper component 24 is used to grab food and put it into an open bag, and the gripper component 24 is a mechanical hand or a clamping mechanism that is currently very mature in the market and will not be described here; a mechanism such as a lead screw transmission, a pneumatic cylinder, an oil cylinder, or an electric push rod can be arranged on the third mounting seat 23 to control the lifting and lateral movement of the gripper component 24 relative to the third mounting seat 23; similarly, a lead screw transmission, a pneumatic cylinder, an oil cylinder, or an electric push rod can be arranged on the second mounting seat 22 to control the left and right movement of the third mounting seat 23, so that the gripper component 24 can lift and move laterally after grabbing food, thereby putting the food into the bag.

[0034] In addition, the third mounting seat 23 is connected to one end of a linkage rod 25, and the other end of the linkage rod 25 is connected to a bag storage frame 102; that is, the third mounting seat 23 and the bag storage frame 102 move synchronously in the left and right directions, so that when the third mounting seat 23 moves towards the bag, the bag storage frame 102 and the bag outlet bin 101 connected thereto will simultaneously move away from above the bag, achieving the purpose of avoiding the gripper component 24, which is conducive to the gripper component 24 putting food into the bag.
