Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] Such as Figures 1 to 5The figure shows an automatic disordered bag arranging machine provided by the present utility model. In this embodiment, it includes a cabinet 60, a bag storage bin 20, a lifting conveyor belt mechanism 30, a feeding conveyor belt mechanism 40, and three groups of bag arranging conveyor belt mechanisms 10. The bag storage bin 20 is fixed at the bottom of the lifting conveyor belt mechanism 30. The feeding conveyor belt mechanism 40 is horizontally arranged relative to the top of the lifting conveyor belt mechanism 30, and the top of the lifting conveyor belt mechanism 30 is connected to the conveying front end, i.e., the left end, of the feeding conveyor belt mechanism 40. The bag storage bin 20, the lifting conveyor belt mechanism 30, and the feeding conveyor belt mechanism 40 are fixed on the bottom plate of the cabinet 60 through brackets. The three groups of bag arranging conveyor belt mechanisms 10 are arranged in parallel with the lifting conveyor belt mechanism 30 and are arranged in layers from top to bottom on the front wall of the cabinet 60. The conveying end, i.e., the right end, of the feeding conveyor belt mechanism 40 is higher than and connected to the first-layer bag arranging conveyor belt mechanism 10. The layered arrangement of the bag arranging conveyor belt mechanisms 10 greatly reduces the sizes of the bag storage bin 20 and the cabinet 60, reduces the space occupied by the bag arranging machine, and lowers the manufacturing cost.

[0031] As Figure 1 and Figure 3 shown, each of the multi-layer bag arranging conveyor belt mechanisms 10 includes a sub-packaging conveyor belt mechanism 1 and a roller conveyor mechanism 2. Each sub-packaging conveyor belt mechanism 1 is located at the head end of the roller conveyor mechanism 2 of the same layer. In the first-layer bag arranging conveyor belt mechanism 10, the sub-packaging conveyor belt mechanism 1 receives the feeding conveyor belt mechanism 40. In the other-layer bag arranging conveyor belt mechanisms 10, the sub-packaging conveyor belt mechanism 1 receives the end of the roller conveyor mechanism 2 of the upper layer. The packaging bags fall from the feeding conveyor belt mechanism 40 to the first-layer sub-packaging conveyor belt mechanism 1 and then fall from the roller conveyor mechanism 2 of the upper layer to the sub-packaging conveyor belt mechanism 1 of the lower layer. During this process, the packaging bags can be effectively separated to widen the distance between the packaging bags, thereby improving the ability of the bag arranging machine to disperse the packaging bags.

[0032] As Figure 3 shown, the roller conveyor mechanism 2 includes a fixing plate 3 and a plurality of roller group mechanisms 4 that continuously increase in speed along the conveying direction. The plurality of roller group mechanisms 4 are fixed on the fixing plate 3. As Figure 4As shown in the figure, each drum group mechanism 4 includes a driver 41, a synchronous pulley structure 42, and multiple drums 43. The output end of the driver 41 is drivingly connected to the active end of the synchronous pulley structure 42, and the driven end of the synchronous pulley structure 42 is respectively connected to the multiple drums 43. That is, the drum group mechanism 4 realizes the conveyance of packaging bags by the driver 41 driving the synchronous pulley structure 42 to rotate and driving the multiple drums 43 to rotate. In each drum group mechanism 4, the speeds at which the driver 41 drives the drums 43 to rotate are inconsistent, and the driving speeds of the multiple drum group mechanisms 4 increase continuously along the conveying direction, so as to form multiple differential speeds. With the assistance of the multiple differential speeds, the packaging bags are continuously pulled apart. Since the bag arranging machine of the present utility model is provided with a multi-layer drum conveying mechanism 2, and each layer of the drum conveying mechanism 2 is provided with multiple drum group mechanisms 4, the number of the drum group mechanisms 4 is greatly increased, thereby greatly improving the bag arranging ability and efficiency of the bag arranging machine;

[0033] The drum group mechanism 4 uses the synchronous pulley structure 42 to connect the driver 41 and the multiple drums 43, greatly reducing noise, not requiring lubrication, reducing maintenance costs, and having a relatively simple structure, thereby further reducing the manufacturing cost;

[0034] In addition, as Figure 1 and Figure 2 shown in the figure, a signal sensor 5 is provided above the first-layer sub-packaging conveyor belt mechanism 1 to sense the entry of the packaging bag into the first-layer sub-packaging conveyor belt mechanism 1 and start the operation of the sub-packaging motor through a signal; a signal sensor 5 is also provided at the front end of each drum group mechanism 4 to sense the position of the packaging bag on the drum group mechanism 4 and start the driver 41 of the next drum group mechanism 4 to increase the speed through a signal;

[0035] During specific operation, the packaging bags filled with materials are poured into the storage bag bin 20. Under the guidance of the four walls of the storage bag bin 20, the packaging bags fall to the bottom of the lifting conveyor belt mechanism 30 and are lifted to the feeding conveyor belt mechanism 40 along with the lifting conveyor belt mechanism 30. Then, they are transferred from the feeding conveyor belt mechanism 40 to the first-layer sub-packaging conveyor belt mechanism 1. At this time, the signal sensor 5 above the first-layer sub-packaging conveyor belt mechanism 1 senses the position of the packaging bag and starts the motor of the sub-packaging conveyor belt mechanism 1. The sub-packaging conveyor belt mechanism 1 conveys the packaging bag to the first-layer roller conveyor mechanism 2. The roller conveyor mechanism 2 continues to convey the packaging bag. During the conveying process, the signal sensor 5 at the front end of each roller group mechanism 4 senses the position of the packaging bag and starts the driver 41 of the next roller group mechanism 4 to form multiple differential speeds. Under the action of the multiple conveying differential speeds, the distance between the packaging bags is gradually widened; then the packaging bag falls from the first-layer end roller group mechanism 4 to the second-layer sub-packaging conveyor belt mechanism 1, then continues to enter the roller conveyor mechanism 2 and experiences the conveying differential speed again, and the overlapping area between the packaging bags becomes smaller and smaller; then it falls from the second-layer end roller group mechanism 4 to the third-layer sub-packaging conveyor belt mechanism 1. At this time, the packaging bags are conveyed independently. Along with the conveying differential speed, the distance between the packaging bags becomes larger and larger, and they are conveyed in sequence one by one. Finally, they fall into the cartoning machine for cartoning.

[0036] Further, as Figure 4 shown, the synchronous pulley structure 42 includes a synchronous belt 421, a driving synchronous pulley 422, a tensioning synchronous pulley 423, and a plurality of driven synchronous pulleys 424. The output end of the driver 41 is drivingly connected to the driving synchronous pulley 422. The plurality of driven synchronous pulleys 424 are connected to a plurality of rollers 43. The tensioning synchronous pulley 423 is located between the driving synchronous pulley 422 and the driven synchronous pulleys 424. Guide structures 425 are provided between the driving synchronous pulley 422 and the tensioning synchronous pulley 423 and between adjacent driven synchronous pulleys 424. The synchronous belt 421 is wound around the driving synchronous pulley 422, the tensioning synchronous pulley 423, the plurality of driven synchronous pulleys 424, and the guide structures 425;

[0037] During specific operation, the driver 41 drives the driving synchronous pulley 422 to rotate, driving the synchronous belt 421 to drive the tensioning synchronous pulley 423, the plurality of driven synchronous pulleys 424, and the guide structures 425 to rotate, thereby driving the plurality of rollers 43 to rotate; the setting of the tensioning synchronous pulley 423 can adjust the tightness of the synchronous belt 421, reduce the vibration during the operation of the synchronous belt 421, and prevent the synchronous belt 421 from slipping, thereby ensuring the normal and stable operation of the synchronous pulley structure 42; the setting of the guide structures 425 can provide an accurate movement path, improve the transmission accuracy, and ensure the stable operation of the synchronous pulley structure 42.

[0038] Further, as Figure 3As shown, both the material passing conveyor belt mechanism 40 and the sub-packaging conveyor belt mechanism 1 are provided with conveyor belts 11. Belt conveying is adopted instead of roller conveying, which can prevent the packaging bags from being inserted into adjacent rollers when they fall, thus affecting the conveying.

[0039] Furthermore, when the packaging bags fall from the upper-layer roller conveying mechanism 2 to the lower-layer sub-packaging conveyor belt mechanism 1, the phenomenon that the packaging bags stand upright may occur. Therefore, as Figure 1 and Figure 2 shown, a guiding member 6 is arranged between the leading-layer bag arranging and conveying mechanisms 10, and the guiding member 6 is arranged at the connection between the sub-packaging conveyor belt mechanism 1 and the roller conveying mechanism 2. During operation, the standing packaging bags are conveyed by the sub-packaging conveyor belt mechanism 1 and guided by the arc inclined surface of the guiding member 6 at the connection, and then will be inverted on the same-layer roller conveying mechanism 2 for normal conveying.

[0040] Furthermore, as Figure 1 and Figure 2 shown, a reverse brush wheel 7 is rotatably arranged above the second-layer roller conveying mechanism 2. The reverse brush wheel 7 is drivingly connected to a motor, and the motor drives the reverse brush wheel 7 to rotate in the direction opposite to the conveying direction of the packaging bags. Therefore, when the packaging bags on the second-layer roller conveying mechanism 2 pass under the reverse brush wheel 7, the reverse brush wheel 7 will squeeze the packaging bags to flatten them and will also disperse some of the stacked packaging bags in the reverse direction, improving the ability of the bag arranging machine to disperse the packaging bags.

[0041] Furthermore, as Figure 1 and Figure 2 shown, the bag arranging machine further includes a pressing mechanism 50. The pressing mechanism 50 is located at the end of the last-layer bag arranging and conveying mechanism 10 and is fixed on the side wall of the cabinet 60. As Figure 5 shown, the pressing mechanism 50 includes a material tray 51, a front pressing mechanism 52, a side pressing mechanism 53 and a top pressing mechanism 54. A material discharging opening 55 is provided on the material tray 51. The front pressing mechanism 52 is located in front of the material discharging opening 55, the side pressing mechanism 53 is located on the side of the material discharging opening 55, and the top pressing mechanism 54 is located above the material discharging opening 55. After the packaging bags are conveyed by the last-layer roller group mechanism 4, they will enter the material tray 51 one by one in sequence. At this time, the front pressing mechanism 52 squeezes the packaging bags at the front end, the side pressing mechanism 53 squeezes the packaging bags on the side, and the top pressing mechanism 54 squeezes the packaging bags from top to bottom, so that they can be smoothly loaded into the packaging boxes on the box loading machine through the material discharging opening 55. The setting of the pressing mechanism 50 is applicable not only to the packaging bags with dimensions less than or equal to the opening of the packaging box, but also to the packaging bags with dimensions larger than the opening of the packaging box, thus making the bag arranging machine have a wider application range.

[0042] Furthermore, as Figure 3As shown in the figure, a baffle plate 12 is provided at the front section of each sub-packaging conveyor belt mechanism 1. When the packaging bag falls from the material-passing conveyor belt mechanism 40 to the first-layer sub-packaging conveyor belt mechanism 1 or falls from the upper-layer roller conveyor mechanism 2 to the lower-layer sub-packaging conveyor belt mechanism 1, the baffle plate 12 can prevent the packaging bag from deviating from the conveying path.

[0043] In summary, the bag arranging machine of the present utility model is provided with multiple groups of bag arranging conveyor mechanisms 10, and the multiple groups of bag arranging conveyor mechanisms 10 are arranged in layers from top to bottom. The layered arrangement greatly reduces the occupied space and manufacturing cost of the bag arranging machine, and since the packaging bags can be separated when falling between layers, the ability to disperse the packaging bags is improved; the bag arranging conveyor mechanism 10 includes a roller conveyor mechanism 2, and the roller conveyor mechanism 2 includes multiple roller group mechanisms 4. The bag arranging machine forms multiple differential speeds through continuous speed increase between the multiple roller group mechanisms 4 to widen the distance between adjacent packaging bags. Since the bag arranging machine is provided with multiple bag arranging conveyor mechanisms 10, the number of roller group mechanisms 4 is greatly increased, thereby greatly improving the bag arranging ability and efficiency of the bag arranging machine; in addition, the roller group mechanism 4 realizes the conveyance of the packaging bag by driving the synchronous pulley structure 42 to rotate by the driver 41 and driving multiple rollers 43 to rotate. The synchronous pulley structure 42 is relatively simple in structure, can reduce noise, and reduce the manufacturing cost and maintenance cost.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
