[0048] The embodiments of the present application will be further described below with reference to the drawings:

[0049] As shown in the drawings, a bag arranging device of a packaging machine comprises a support 1 and a receiving mechanism 2 mounted on the support 1, wherein the receiving mechanism 2 comprises a third driving member 21 mounted on the support 1 and a wheel rotating member 22 connected with the output end of the third driving member 21, and at least one set of receiving devices 23 is arranged circumferentially on the wheel rotating member 22; the technical solution sets a receiving mechanism below the finished product output device to receive the small packaging bags which are finished products, the third driving member drives the wheel rotating member to rotate, so that the small packaging bags enter the receiving devices one by one, and the packaging bags are neatly arranged in the receiving devices after the receiving devices receive a batch of packaging bags, which facilitates the neat output of the subsequent process and has a good bag arranging effect and good working stability.

[0050] The third driving member is an electric motor.

[0051] The present invention has two technical solutions. In the first technical solution, the rotating component 22 is a vertically arranged turntable; the bracket 1 is provided with a material blocking component 24 arranged around the material receiver 23; the material receiver 23 includes a number of spaced partitions 231, and every two partitions form a frame for receiving materials. Small packaging bags fall between every two partitions. When the material receiver is in the upward receiving position, the material blocking component avoids the falling small packaging bags. After the material receiver has received the small packaging bags, it will gradually rotate to the downward position. During this process, the material blocking component always surrounds the material receiver to prevent the small packaging bags from falling out.

[0052] The material-blocking assembly 24 includes a plurality of first baffles 241 and a plurality of second baffles 242. The first baffles 241 are mounted on the support 1 and are positioned to the side of the turntable, while the second baffles 242 are mounted on the support 1 and are positioned to the bottom of the turntable. A fourth driving component 243 is mounted on the support 1, which is connected to the second baffles 242 and controls their opening and closing. The first baffles 241 are located on the side of the turntable to prevent small packaging bags from falling out. The aforementioned material-blocking assembly avoids falling small packaging bags through the first baffles. Figure 2 As shown, the first baffle 241 does not interfere with the falling of the small packaging bags, and the second baffle can control the falling time of the small packaging bags. When the receiver is facing downwards, the fourth drive unit can control the second baffle to open to both sides, and the same batch of small packaging bags in the receiver will fall downwards into the transfer frame at the same time.

[0053] The number of the first baffle and the second baffle is at least two, and the fourth driving component is a finger cylinder.

[0054] The first technical solution described above has two embodiments:

[0055] Example 1: The receiving mechanism 2 consists of two symmetrically arranged components, with the receiving devices 23 on the two turntables staggered, as shown below. Figure 1 and Figure 2 As shown, each turntable has one feeder, and two motors are symmetrically arranged to drive the turntable to rotate. The two feeders alternately receive and discharge materials.

[0056] Example 2: The receiving mechanism is driven by a motor to rotate a turntable. Each turntable has three sets of receiving devices. The number of receiving mechanisms can be determined according to production capacity; it can be one, two, or three (e.g., ...). Figure 3 As shown in the figure, multiple receiving mechanisms are arranged side by side.

[0057] In the two embodiments described above, a transfer frame 31 is provided below the receiving mechanism 2. The small packaging bags in the receiving device enter the transfer frame under the control of the second baffle, and then the small packaging bags accurately enter the next process through the transfer frame.

[0058] In the second technical solution of the present invention, the rotating component 22 is a conveyor belt assembly; the receiving device 23 includes a plurality of spaced partitions 231.

[0059] The second technical solution has three embodiments:

[0060] Example 3: Figure 5 As shown, when there is only one conveyor belt assembly, one side of the conveyor belt assembly is provided with a first pre-set plate 41 and the other side is provided with a first pushing component 42 that pushes the material onto the first pre-set plate 41. One side of the first pre-set plate 41 is provided with a first blocking component 43 corresponding to the first pushing component 42. The first pre-set plate 41 is provided with a second pushing component 44 that pushes away the material located between the first pushing component 42 and the first blocking component 43.

[0061] The first pushing component 42, the second pushing component 44, and the first blocking component 43 have the same structure but different installation positions. They all include a fifth driving component 45 and a first pushing plate 46 connected to the fifth driving component. The fifth driving component is a cylinder. The first pushing plate of the first blocking component moves upward to a position higher than the first pre-positioned plate. The first pushing plate of the first pushing component pushes the small packaging bag onto the first pre-positioned plate and is blocked by the first pushing plate of the first blocking component. Then, the first pushing plate of the second pushing component pushes the packaging bag to the next process.

[0062] Example 4: Figure 7 As shown, when there are two conveyor belt assemblies, one is a first conveyor belt assembly 51 and the other is a second conveyor belt assembly 52. ​​The first conveyor belt assembly 51 is provided with a third pushing component 7 on one side to push the material out of the first conveyor belt assembly 51; the second conveyor belt assembly 52 is provided with a fourth pushing component 8 on one side to push the material out of the second conveyor belt assembly 52.

[0063] The third pushing component 7 and the fourth pushing component 8 have the same structure. The third pushing component 7 includes:

[0064] The sixth drive unit 711 is horizontally positioned and located above the first conveyor belt assembly 51;

[0065] The seventh driving component 712 is installed vertically downward at the output end of the sixth driving component 711;

[0066] The second pre-set plate 713 is disposed on one side of the first conveyor belt assembly 51;

[0067] The second push plate 714 is in the shape of an inverted U and is fixedly installed at the output end of the seventh drive member 712;

[0068] The second push plate 714 has a first action of descending from above the first conveying belt assembly 51 and inserting into the material receiver 23, a second action of pushing the material in the material receiver 23 to the second preset plate 713, and a third action of pushing the material on the second preset plate 713 away;

[0069] The side wall of the second push plate 714 can be in the form of a comb matched with the material receiver 23, or in the form of a straight plate with a height difference from the material receiver 23. When the second push plate 714 is in the form of a comb (as shown in FIG. 7B), the second push plate 714 directly enters between the adjacent two partitions of the material receiver 23 to push the small packaging bags away. When the second push plate 714 is in the form of a straight plate (not shown in the figure), the second push plate 714 contacts the part of the small packaging bags exposed outside the material receiver 23, and the small packaging bags can be pushed away without contacting the material receiver 23. Figure 8

[0070] The second preset plate 713 is provided with a first limiting plate 715 and a first material pressing component arranged oppositely and located on both sides of the second push plate 714. The first material pressing component includes an eighth driving member 716 and a first material pressing plate (not shown in the figure) connected with the output end of the eighth driving member 716. The first material pressing component compresses the material after the second push plate 714 finishes the second action and before the third action starts. The sixth driving member, the seventh driving member, and the eighth driving member are all in the form of a pneumatic cylinder. Under the action of the sixth driving member and the seventh driving member, the second push plate pushes a batch of small packaging bags on the first conveying belt assembly to the second preset plate. At this time, the eighth driving member drives the first material pressing plate to compress the small packaging bags on the second preset plate. After compression, the second push plate pushes the small packaging bags away again. The first conveying belt assembly 51 and the second conveying belt assembly on both sides push a plurality of batches of small packaging bags away in turn, greatly improving the work efficiency.

[0071] Embodiment five: as shown in FIG. 7C, when the number of conveying belt assemblies is two, one of which is the first conveying belt assembly 51 and the other of which is the second conveying belt assembly 52, the first conveying belt assembly 51 is provided with a third material pushing component 7 on one side for pushing the material out of the first conveying belt assembly 51; and the second conveying belt assembly 52 is provided with a fourth material pushing component 8 on one side for pushing the material out of the second conveying belt assembly 52. Figure 9

[0072] The third material pushing component 7 includes:

[0073] A ninth driving member 721 is horizontally arranged above the first conveying belt assembly 51;

[0074] A tenth driving member 722 is vertically downwardly mounted on the output end of the ninth driving member 721;

[0075] An eleventh driving member 723 is arranged on one side of the first conveying belt assembly 51, and the output end of the eleventh driving member 723 is provided with a third baffle 724; ​​

[0076] a first preset frame 725 arranged on one side of the first conveying belt assembly 51;

[0077] a third pushing plate 726 fixedly installed on the output end of the tenth driving member 722;

[0078] The third pushing plate 726 is comb-shaped and matched with the material receiver 23. The first preset frame 725 comprises an upper frame 7251 and a lower frame 7252 arranged in an up-down manner and matched with the third pushing plate 726. A gap is arranged between the upper frame 7251 and the lower frame 7252 for the third blocking plate 724 to pass through. The ninth driving member, the tenth driving member and the eleventh driving member are all air cylinders. The eleventh driving member drives the third blocking plate 724 to insert into the gap between the upper frame and the lower frame, so as to block a batch of small packaging bags pushed by the third pushing plate. When the third pushing plate is pushed to the position, the third blocking plate 724 is withdrawn, and then the small packaging bags are accurately discharged from the first preset frame.

[0079] The third blocking plate 724 is L-shaped.

[0080] A first material blocking strip 53 is arranged on the second conveying belt assembly 52 along the material movement track and prevents the material from falling downward. Figure 11 As shown in the figure, the first material blocking strip has a curved end and a straight end, which can prevent the small packaging bags from falling off at the bending section and downward section of the second conveying belt assembly.

[0081] The fourth pushing member 8 comprises:

[0082] A second preset frame 81 is arranged directly below the second conveying belt assembly 52.

[0083] A twelfth driving member 82 is arranged on one side of the second preset frame 81, and the output end of the twelfth driving member 82 is provided with a second material blocking strip 83 matched with the first material blocking strip 53. The matching means that there is no gap between the first material blocking strip and the second material blocking strip, so that the small packaging bags will not fall down in the gap.

[0084] The second material blocking strip 83 is arranged between the second preset frame 81 and the second conveying belt assembly 52.

[0085] The twelfth driving member is an air cylinder, which controls the opening and closing of the second material blocking strip. The working principle of the fourth pushing member is similar to that of the second embodiment. The difference lies in that one is a rotating disc and the other is a conveying belt mechanism. The small packaging bags are accurately discharged through the second preset frame, and the orientation of the small packaging bags is opposite to that of the small packaging bags at the first conveying belt assembly. Here, the opposite orientation means that the opposite sides of the small packaging bags are opposite, one upward and the other downward.

[0086] The third pushing component 7 and the fourth pushing component 8 in the fifth embodiment are different in structure, and the effect achieved by the embodiment is that the orientations of two adjacent small packaging bags must be opposite before the two batches of small packaging bags are collected in the middle, and the structure is suitable for packaging bags such as instant noodle seasoning bags, because if the orientations of the packaging bags are uniform, the left and right heights will be unbalanced when the packaging bags are stacked up and down in the subsequent process, and thus the packaging bags will be overturned, and therefore, the structure of the embodiment is used to make the small packaging bags from the first conveying belt assembly and the second conveying belt assembly into two batches with opposite orientations, and the small packaging bags with the same orientation are arranged at intervals in the subsequent collection process, so that when the small packaging bags are stacked up and down, the left and right heights will not be unbalanced, and thus the small packaging bags will not be overturned.

[0087] The material mentioned above is a small packaging bag that has been formed.

[0088] In addition, the guiding piece 11 is hingedly arranged on the support 1 and located on one side of the receiving mechanism 2, the support 1 is provided with a thirteenth driving piece 12 that is hingedly connected with the guiding piece 11 and drives the guiding piece 11 to swing in the horizontal direction; the thirteenth driving piece can adjust the swing angle of the guiding piece, so that the outlet of the guiding piece can be aligned with the receiver or not aligned with the receiver, and the guiding piece 11 adopts a guiding channel made of a plate material, the size of the inlet of the guiding channel is greater than the size of the outlet of the guiding channel, and the guiding piece can be applied to the above-mentioned five embodiments, so as to ensure that the small packaging bag that has been formed can enter the receiver stably.

[0089] The application also provides another technical scheme, a packaging machine, which comprises a film receiving device 91, a small packaging bag forming device 92, a longitudinal sealing device 93, a material filling device 94, a heat sealing device 96 and a finished product output device 95, and further comprises the bag arranging device as described above arranged below the finished product output device 95, and has all the beneficial effects of the bag arranging device.
