[0046] The present utility model provides a packaging bag feeding structure suitable for upper feeding, which is used in a feeding device. The present utility model does not limit the type of materials, but this packaging bag feeding structure suitable for upper feeding is particularly suitable for the packaging of candies, coffee beans and coffee powder.

[0047] Generally speaking, the feeding structure for packaging bags applicable to top feeding proposed by the present utility model mainly includes a frame 1, a conveying unit, a claw-expanding feeding and receiving unit, a lifting unit, and a claw-expanding unit. Among them, reference can be made to Figure 1 , which shows the layout relationship of the frame 1, the conveying unit, the claw-expanding feeding and receiving unit, the lifting unit, and the claw-expanding unit.

[0048] In order to achieve the purpose of ensuring that the materials accurately enter the packaging bags and can also adapt to materials of different shapes and sizes, to solve the problem in the background technology that when the packaging bags are conveyed to the loading structure area, candies, coffee beans, and coffee powder need to smoothly enter the packaging bags. However, due to different blanking structures, it is impossible to ensure that all the materials transmitted from above can accurately enter the packaging bags below. On the one hand, the shapes and sizes of the materials are not the same. On the other hand, the materials will be scattered due to the influence of wind, vibration, or other external factors during the falling process, and it is impossible to ensure that the blanking point always remains the same. Therefore, it is also impossible to ensure that the materials can be firmly caught by the packaging bags below. For this reason, in the technical solution provided in this embodiment, the claw-expanding unit is used to achieve the function of receiving materials after the claws are closed, and then combined with the lifting unit and the claw-expanding unit to ensure that the materials accurately enter the packaging bags downward, can also adapt to materials of different shapes and sizes, effectively improve the packaging efficiency and stability, and reduce manual intervention and labor intensity.

[0049] As Figure 1 shown, a horizontally arranged conveying unit is installed on the device through the frame 1, which is used to transfer the materials from one end of the source to one end of the packaging bag. A claw-expanding feeding and receiving unit is arranged below the discharging direction of the conveying unit. The claw-expanding feeding and receiving unit is used to catch the materials conveyed by the conveying unit, collect and converge them, and then centrally output them from the bottom into the packaging bag. In addition, the lifting unit is used to cooperate to realize the height of the claw-expanding feeding and receiving unit approaching the conveyor belt to receive materials and feeding the packaging bag up and down, and the claw-expanding unit can also be used to ensure that the materials accurately enter the packaging bag.

[0050] As described above, since the materials usually conveyed in this embodiment are relatively small particles, such as candies, coffee beans, etc., the conveying unit used includes a conveyor belt 2. The driving wheel 3 and the driven wheel 4 are respectively installed at both ends of the conveyor belt 2. The driven wheel 4 is arranged close to the claw-expanding feeding and receiving unit. One end of the driving wheel 3 is installed with a synchronous belt wheel 5 and a synchronous belt 6. The driving motor 7 is connected to the synchronous belt wheel 5 to realize the rotary feeding function of the conveyor belt 2. In addition, a plurality of partition blocks 10 are arranged at equal intervals on the conveyor belt 2. The partition blocks 10 can be used to keep the candies and coffee beans arranged in an orderly manner on the conveyor belt 2, reduce chaos and accumulation phenomena, thereby improving the transportation efficiency. The orderly transmission can also ensure that the candies and coffee beans can enter the next processing link evenly and stably.

[0051] On this basis, baffles 8 are also installed on the support plates 9 on both sides of the conveyor belt 2. One end of the baffle 8 close to the discharging direction of the conveyor belt 2 is arranged close to the center position of the claw-expanding feeding and discharging unit. The baffle 8 can effectively prevent materials from falling due to environmental, angular and other problems during the conveying process, especially for round granular materials that are prone to slipping, ensuring that the materials can reach the designated position smoothly.

[0052] Specifically, for the claw-expanding feeding and discharging unit, as shown in the figure, the claw-expanding feeding and discharging unit includes a first claw 18 and a second claw 19. The first claw 18 is inclined, and the second claw 19 is oppositely arranged on one side of the first claw 18 close to the conveyor belt 2. The second claw 19 is inclined in the opposite direction to the first claw 18. Since both sides of the first claw have side baffle strips 20 extending in the direction of the conveyor belt 2 to form a pair of parallel side baffle strips, during use, when the first claw 18 and the second claw 19 are closed, they are nested with each other. The side baffle strips 20 surround the outer side surface of the second claw 19, and their tops form a feeding port 21, and the bottoms are close to each other. When the first claw 18 and the second claw 19 are separated, a discharging channel is formed at the bottom;

[0053] Preferably, in order to achieve the concentration of the discharging process, the bottoms of the first claw 18 and the second claw 19 extend downward to form vertical guide plates 22, which are convenient for concentration after closing and also convenient for guiding the discharging after the claws are expanded.

[0054] The driving structure for driving the first claw 18 and the second claw 19 to close or separate comes from the claw-expanding unit. Inside the claw-expanding unit, the holding arms 15 are respectively connected to the outer sides of the first claw 18 and the second claw 19. The other ends of the holding arms 15 are installed on both sides of the claw-expanding cylinder 14, and the holding arms 15 are perpendicular to the conveyor belt 2. The claw-expanding cylinder 14 for driving the holding arms 15 to move towards both sides is installed below the claw-expanding cylinder connecting block 13. The claw-expanding cylinder connecting block 13 is installed at the end of the cylinder shaft of the lifting cylinder 12, which can achieve the effect of driving the holding arms 15 to drive the first claw 18 and the second claw 19 to move up and down with the action of the lifting cylinder 12.

[0055] In addition, a first limiting plate 16 is vertically arranged between the holding arm 15 and the lifting cylinder 12. Similarly, a vertical second limiting plate 17 is also arranged at one end of the claw-expanding cylinder connecting block 13 close to the first limiting plate 16, which helps the operator to achieve accurate alignment of the installation position during the installation process, and uses the bottom of the second limiting plate 17 to form the top guiding effect when the two holding arms 15 move horizontally on both sides, so that the movement of the first claw 18 and the second claw is also horizontally aligned, always maintaining the corresponding structure, which is beneficial to the stability of material collection and feeding.

[0056] Such as Figure 3As shown in the figure, the lifting unit includes a lifting cylinder connecting block 11 and a lifting cylinder 12 installed at the bottom of the lifting cylinder connecting block 11. The lifting cylinder connecting block 11 is horizontally installed on the top of the frame 1. The base of the lifting cylinder 12 is connected to the lifting cylinder connecting block 11, and the cylinder shaft moves up and down downward.

[0057] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
