In particular, as shown in fig. 4, the first rotating brush 31 includes a rotating shaft 311 linked to the linkage mechanism 20 and flexible members 312 uniformly distributed on the surface of the rotating shaft 311, the flexible members 312 can be automatically deformed by the pressure of the packaging bag, so that the packaging bag transferring device 100 is suitable for transferring packaging bags with different volumes, wherein the structure of the second rotating brush 32 is the same as that of the first rotating brush 31.

It should be noted that the flexible member 312 may be a plastic member, that is, the first rotating brush 31 and the second rotating brush 32 are both soft brush brushes, so that the flexible member can adapt to the automatic deformation of the articles in the packing bag while ensuring a certain transmission power.

Further, the packing bag transferring apparatus 100 further includes a fixing plate 40 perpendicular to the first transfer belt 33, wherein the motor 10 and the link mechanism 20 are installed at one side of the fixing plate 40, and the first rotating brush 31, the second rotating brush 32 and the first transfer belt 33 are installed at the other side of the fixing plate 40.

It should be noted that the first transmission belt 33 includes two rotation shaft members 331 linked to the linkage mechanism 20 and a transmission belt 332 rotated by the two rotation shaft members 331 in a linkage manner, and the two rotation shaft members 331 are rotated by the linkage mechanism 20 in a linkage manner to drive the transmission belt 332 to rotate.

In particular, the gear assembly is a variable speed reversing gear assembly, that is, the package transfer apparatus 100 employs a variable speed reversing gear assembly to realize the guide structure of the bidirectional paired rollers of the first rotating brush 31 and the second rotating brush 32.

In some embodiments of the present invention, the package conveying device 100 may also use a linkage structure such as a chain, a worm gear, a belt, etc. to realize the bidirectional rotation of the first rotating brush 31 and the second rotating brush 32, which is not limited by the present invention.

In another embodiment of the present invention, as shown in fig. 5, the package bag transferring apparatus 100 further includes a second transfer belt 50 disposed on the transfer path of the package bag, and an included angle between the second transfer belt 50 and the first transfer belt 33 is greater than 90 °, so that in the use state of the package bag transferring apparatus 100, the transfer surface of the second transfer belt 50 is located lower than the transfer surface of the first transfer belt 33, so that the package bag transferred from the first transfer belt 33 can be transferred on the second transfer belt 50 by its own weight.

It can be understood that, when a package is transported from the first transporting belt 33 to the second transporting belt 50, because there is a transition gap between the first transporting belt 33 and the second transporting belt 50, which is very easy to cause the package to jam and block, in order to avoid the jam at the transition interface between the first transporting belt 33 and the second transporting belt 50, the package transporting apparatus 100 adopts a step structure 101 with a high front and a low back, i.e. the fixing plate 40 protrudes from the back plate 51, so that the transporting width of the first transporting belt 33 is smaller than the transporting width of the second transporting belt 50, thereby ensuring the package to be transported from the first transporting belt 33 to the second transporting belt 50 without jam, and with this structure, the difficulty of manufacturing and processing of the transition interface between the first transporting belt 33 and the second transporting belt 50 can be reduced, the production cost is reduced, and the automation and the mechanization of the packaging bag conveying are facilitated.

In particular, a semi-open conveying space 102 is formed between the back plate 51 and the second conveyor 50, so as to facilitate checking of the conveying condition of the second conveyor 50 and the loading and unloading of the packing bags, and facilitate the maintenance of the second conveyor 50.

That is, the packing bag transferring device 100 of the present invention adopts a single-side open design, that is, only the fixing plate 40 and the back plate 51 are provided, and no baffle is provided at a side of the fixing plate 40 opposite to the back plate 51, so that the packing bag transferring process of the packing bag transferring device 100 can be clearly viewed, and the packing bag loading and unloading and the maintenance of the packing bag transferring device 100 can be facilitated.

It is worth mentioning that the packaging bag conveying device 100 further comprises a plurality of gravity balances 52 and a pre-pressing member 53 rotatably connected to the back plate 51, the gravity balances 52 are swingably mounted on the back plate 51 and positioned above the second conveying belt 50, and the gravity balances 52 and the pre-pressing member 53 are used for providing a pre-pressing force for the packaging bags conveyed from the first conveying belt 33 so as to prevent the packaging bags conveyed on the second conveying belt 50 from slipping and jamming.

It can be understood that, when the packing bag is transported on the second conveyor belt 50, the gravity balance 52 can swing up and down flexibly and always press on the packing bag to provide a certain pre-pressure, so that the packing bag can always keep in contact with the second conveyor belt 50, and the friction force between the packing bag and the second conveyor belt 50 can be kept in a fixed range, thereby avoiding the situation that the packing bag can not contact the second conveyor belt 50 and the slipping jam occurs, and meanwhile, the gravity balance 52 can be adapted to different articles in the packing bag to float up and down freely, so that the packing bag transporting device 100 can be suitable for transporting various packing bags.

It is also worth mentioning that a plurality of mounting members 54 parallel to the second conveying belt 50 are mounted on the back plate 51, and the gravity balance 52 is rotatably mounted on the corresponding mounting members 54.

It will be appreciated that the back plate 51 provides assembly space for the plurality of gravity balances 52 and the pre-compression members 53, so that the overall structure of the bag transferring device 100 is compact, flexible and convenient to use.

It should be noted that the pre-pressing member 53 includes a pivot shaft 531 pivoted to the back plate 51, a pre-pressing plate 532 connected to the pivot shaft 531, and a pre-pressing shaft 533 integrally formed on the pre-pressing plate 532, wherein the pre-pressing shaft 533 presses the packaging bags conveyed on the second conveyor 50 by its own weight and can rotate along the pivot shaft 531 to adaptively provide corresponding pre-pressing forces for packaging bags with different volumes.

The bag conveyor 100 accomplishes bag output through a series of mechanical structures: firstly, the direction of the packaging bag is controlled by the first rotating brush 31 and the second rotating brush 32 with opposite rotating directions; secondly, the transverse steering of the packaging bag is realized in a transverse transmission friction mode through the first conveying belt 33; then, since the conveying surface of the second conveying belt 50 is lower than the conveying surface of the first conveying belt 33 in the use state, the side-by-side conveying of the packaging bags on the second conveying belt 50 is realized by means of oblique gravity, and a structure that the fixing plate 40 protrudes out of the back plate 51 is adopted at the transition interface of the first conveying belt 33 and the second conveying belt 50, so that the conveying width of the first conveying belt 33 is smaller than that of the second conveying belt 50, and the packaging bags can be smoothly and transitionally conveyed from the first conveying belt 33 to the second conveying belt 50 without jamming; moreover, in order to adapt to the articles in different packaging bags (articles with different sizes, volumes, heights or weights in the packaging bags), the friction force is balanced in a pre-pressing mode through the gravity balance wheel 52; in addition, a single-side opening structure is adopted, so that the packaging bags can be easily taken out and put in the conveying process, and the packaging bags can be conveniently and quickly taken and put.

In general, the invention provides the packaging bag conveying device 100 which has the advantages of simple structure, convenience and flexibility in use, no blockage in conveying and wide application range, and can realize full-automatic and mechanized conveying of packaging bags.
