Description

Technical Field

[0001] The present invention belongs to the technical field of packaging, and particularly relates to an automatic bagging device. Background Art

[0002] Common commodities such as bagged rice, flour, soybean meal, and cement on the market are usually bagged manually with woven bags. A large amount of dust is generated during the bagging operation, which affects the health of the bagging workers. Therefore, many factories adopt automatic production lines for bagging.

[0003] A Chinese patent with the authorization announcement number CN111216970B discloses a rice bagging and packing device, which includes an installation table, a conveying device, a compressing device, a feeding device, a sealing device, and a power device. The conveying device includes a transport component a; the compressing device includes a transport component b, a bag closing component, and a pressing component; the feeding device includes a feeding component and a fixing component; the sealing device includes a sewing machine and a control component, and the power device includes a driving component a and a driving component b. After quantitatively loading rice into the woven bag, the bag closing component moves closer to the middle to close the woven bag, and after closing, the pressing component moves down to press the rice, and then the woven bag is sealed by the sewing machine. It solves the technical problem that the woven bag filled with rice is not closed and pressed during sealing in the prior art, resulting in uneven sealing and thus insecure sealing.

[0004] Although this type of packing device can partially achieve automatic packing and reduce the problem of dust inhalation by workers, it still requires workers to put the woven bag on the storage bin of its feeding device manually. And some dust will escape around when the storage bin discharges materials, and workers will inhale the dust during the previous discharging when putting on the bag, which affects the health of workers. Therefore, it is necessary to design a new solution to solve the problem of workers inhaling dust. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0051] In one embodiment of the present invention, as Figure 1 - Figure 2 shown, an automatic bagging device is provided, which includes a frame 100 and a bag hanging device 200, a bag sleeving device 300, a feeding device 400, a bag conveying device 500, and a sealing device 600 provided on the frame 100.

[0052] Above the frame 100, a transition hopper 110 is provided, the transition hopper 110 is connected to the feeding device 400, and above the transition hopper 110, a weighing scale 120 is provided.

[0053] The bag hanging device 200 is used for hanging woven bags. As Figure 3 - Figure 4 shown, the bag hanging device 200 includes a fixed bracket 210, a rotating bracket 220, a rotating assembly 230, and a plurality of feeding assemblies 240.

[0054] The fixed bracket 210 is fixed on the frame 100.

[0084] The bag feeding device 500 is arranged at the bottom of the feeding device 400, and the bag feeding device 500 is used to convey the woven bag after loading to the sealing device 600. As Figure 9 - Figure 11 shown, the bag feeding device 500 includes a conveyor belt 510, a trolley 520 and two closing assemblies 530.

[0085] The conveyor belt 510 is arranged below the feeding device 400. The structure of the conveyor belt 510 is a conventional prior art in this field and will not be described in detail here. Guardrails 511 are arranged on both sides of the conveyor belt 510 to prevent the woven bag after loading from tipping over. A coding mechanism 512 is arranged beside the conveyor belt 510.

[0086] The trolley 520 is arranged below the feeding device 400 and above the conveyor belt 510. The trolley 520 moves reciprocally and is used to transfer the woven bag after loading onto the conveyor belt 510. In this embodiment, side plates 521 are arranged on both sides of the trolley 520, and a hand guard mechanism 522 for fastening the woven bag after bagging is arranged on the side plates 521.

[0087] The two closing assemblies 530 are arranged on the trolley 520, and the two closing assemblies 430 are respectively arranged on the tops of the side plates 521. The closing assembly 530 is used to fit the opening of the woven bag after loading. Here, "fitting" means that the inner sides of the two sides of the woven bag are temporarily fixed together. Each closing assembly 530 includes a long plate 531 and a closing driving mechanism 532; the long plate 531 is in a long strip shape, and the corresponding two long plates 531 respectively abut against both sides of the top of the woven bag after loading so as to fit the opening of the woven bag; the closing driving mechanism 532 is arranged at the rear side of the long plate 531 and drives the long plate 531 to open and close. The closing driving mechanism 532 is preferably a cylinder.

[0088] The sealing device 600 is arranged beside the feeding device 400 and above the bag feeding device 500. The sealing device 600 is used to seal the opening of the woven bag. In this embodiment, "sealing" means permanently or semi-permanently closing and fixing the opening of the woven bag to prevent the materials therein from leaking during transportation. The sealing method can adopt sewing with a needle and thread, hot pressing at high temperature, puncturing and buckling, a zipper, etc., without limitation. As Figure 12 - Figure 13As shown, the sealing device 600 includes a mounting base 610, and an introduction component 620, an introduction driving component 630, and a sealing component 640 that are fixed to the mounting base 610. The introduction component 620 is located beside the bag feeding device 500. An introduction belt 621 is provided on the introduction component 620, and an introduction channel 622 is provided on the introduction component 620. The introduction driving component 630 drives the introduction belt 621 to rotate, and the introduction driving component 630 is preferably a motor. The sealing component 640 is located above the introduction channel 622, and the sealing component 640 is used to seal the opening of the woven bag. The sealing device 600 further includes a sealing lifting component 650. The sealing device 600 is connected to the frame 100 through the sealing lifting component 650, and the sealing device 600 moves up and down through the sealing lifting component 650 to adjust the sealing position of the woven bag. In this embodiment, the sealing lifting component 650 is driven by a motor. In this embodiment, the opening of the woven bag is sealed by means of sewing with a needle and thread. The sealing component 640 is a sewing machine for woven bags. The sealing device 600 further includes a thread spool 660 for supplying thread to the sealing component 640. The thread spool 660 is located below the sealing component 640 and is fixed to the conveyor belt 510. It should be noted that the height of the sealing portion of the woven bag should be lower than the height of the puncture portion of the bag hanging rod 241. At the same time, the opening of the woven bag can also be folded and then sealed.

[0089] When the bag feeding device 500 and the sealing device 600 are operating, they include the following steps:

[0090] Step S310: After the woven bag is filled with materials, the lateral driving mechanism 433 drives the two clamping members 431 to stretch outwards, so that the opening of the woven bag is closed.

[0091] Step S320: The closing driving mechanism 532 drives the long plate 531 to close inwards, so that the opening of the woven bag fits together, and the clamping driving mechanism 432 drives the clamping members 431 to release the woven bag.

[0092] Step S330: The hand guard mechanism 522 fixes the lower part of the woven bag, and the trolley 520 moves the woven bag to the conveyor belt 510; at the same time, the upper end of the woven bag enters the introduction channel 622.

[0093] Step S340: The sealing component 640 seals the opening of the woven bag.

[0094] Through the above structure, the full-automatic production of processes such as bagging, sleeving, loading, and sealing is realized, effectively improving the production efficiency, reducing the labor cost, and avoiding workers inhaling dust and affecting their physical health.

[0095] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
