[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figure 1 As shown, the present utility model provides a technical solution for an automatic boxing device: An automatic boxing device includes a first frame 1 and a second frame 2. A packaging box conveyor 3 and a material conveyor 9 are respectively arranged on the first frame 1 and the second frame 2. Both the packaging box conveyor 3 and the material conveyor 9 adopt roller conveyors. The packaging box conveyor 3 is used to convey packaging cartons, and the material conveyor 9 is used to convey materials to be loaded into the cartons.

[0035] As Figure 1-3As shown in the figure, a case turning mechanism 4 for guiding and turning the carton is installed on the first frame 1. The case turning mechanism 4 includes a turning rod 42 installed on the cross beam of the first frame 1 through a hinge seat and a turning frame 41 fixedly connected to the turning rod 42. One end of the turning rod 42 is fixedly connected with two turning push plates 43. The other ends of the two turning push plates 43 are rotatably connected with turning cylinders 44. The two turning cylinders 44 are both fixed on the cross beam of the first frame 1. A height-adjustable limit plate 45 is also arranged on one side of the first frame 1. A trigger switch is installed on the side of the limit plate 45. When the packaging carton is transported by the packaging carton conveyor 3, the carton will enter the inside of the turning rod 42. When the transportation is in place, the limit plate 45 will resist and limit the packaging carton. At this time, the packaging carton will touch the trigger switch. At this time, the packaging carton conveyor 3 stops transporting, and the case turning mechanism 4 starts to work.

[0036] As Figure 2 and 3 shown in the figure, the telescopic end of the turning cylinder 44 is rotatably connected with one end of the turning push plate 43. The other ends of the two turning push plates 43 are both fixedly connected with the turning rod 42. The two ends of the turning rod 42 are rotatably connected with the hinge seat. The turning frame 41 is of a "U" shape structure, and a plurality of pushing channels for the convenient passage of the pushing rod 55 are formed on the turning frame 41. When the case turning mechanism 4 works, the two turning cylinders 44 will extend synchronously, thereby pushing the two turning push plates 43 to rotate synchronously. Further, the two turning push plates 43 will drive the turning frame 41 to turn 90 degrees, so that the turning frame 41 turns from the vertical state to the horizontal state. As Figure 3 shown in the figure, after the turning frame 41 turns, it will drive the packaging carton to turn and dump, so that the opening of the packaging carton corresponds to the pushing channel. It should be noted that when the turning frame 41 does not turn, its upper end extends above the packaging carton conveyor 3. When the turning frame 41 turns, the bottom side of the turning frame 41 is flush with the transmission rollers of the packaging carton conveyor 3 and is located between the gaps of every two transmission rollers, so that the packaging carton inside the turning frame 41 is just located on the transmission rollers.

[0037] As Figure 1-3As shown in the figure, a box pushing mechanism 5 for pushing the flipped carton is further provided on the first frame 1. The box pushing mechanism 5 includes limit slide bars 53 symmetrically installed on the first frame 1. A moving plate 52 is slidably connected to the two limit slide bars 53. A box pushing frame 51 is vertically installed on the moving plate 52. A plurality of push rods 55 are equidistantly installed on the inner side of the moving plate 52. The box pushing mechanism 5 further includes a box pushing cylinder 54 installed on the first frame 1. A fixed rod is further provided in the middle of the upper surface of the moving plate 52. The telescopic end of the box pushing cylinder 54 is connected to the top of the fixed rod. The bottom end of the push rod 55 is located above the packing box conveyor 3. After the box turning mechanism 4 turns the packing carton from the vertical state to the dumping state, the box pushing cylinder 54 contracts, which will drive the moving plate 52 to move linearly along the limit slide bar 53. Further, it will drive the push rod 55 through the box pushing frame 51 to push the carton dumped inside the box turning frame 41, and push the carton to the box supporting mechanism 8, so that the box supporting mechanism 8 is inserted into the opening of the carton to realize the support of the carton opening. It should be noted that when the push rod 55 pushes into the box turning frame 41, it is just located in the box pushing channel of the box turning frame 41, and the push rod 55 is located above the packing box conveyor 3, which does not affect the box pushing operation at all;

[0038] As Figure 1 and 4 As shown in FIGS. 5, a packing mechanism 6 for pushing the limited materials into the box is further installed on one side of the second frame 2. The packing mechanism 6 includes limit slide bars 63 symmetrically installed on the second frame 2. A moving plate 62 is slidably connected to the two limit slide bars 63. A loading push frame 61 extending above the material conveyor 9 is vertically installed on the upper surface of the moving plate 62. Two loading push plates 64 corresponding to the loading channel are symmetrically installed on one side of the loading push frame 61. The packing mechanism 6 further includes a loading cylinder 65 installed on the second frame 2. The telescopic end of the loading cylinder 65 is connected to the middle of the upper surface of the moving plate 62. After the packing carton is pushed to the box supporting mechanism 8 by the box pushing mechanism 5, the loading cylinder 65 will contract, thereby driving the moving plate 62 to move linearly along the limit slide bar 63, and further driving the loading push frame 61 to move towards the packing carton. During the movement, the loading push plate 64 will push the materials to be loaded on the material conveyor 9 towards the box opening of the packing box, so as to load the materials into the packing box from the loading channel and complete the automatic packing operation;

[0039] As Figure 1 and 4As shown, a box-supporting mechanism 8 for opening the carton mouth is installed at the outer side of the frame 2 corresponding to the box-turning mechanism 4. The box-supporting mechanism 8 includes two mounting plates 81 symmetrically mounted on the top of the frame 2, and an upper inclined plate 82 is connected to the top of each mounting plate 81, and a side inclined plate 83 is fixed to the side of each mounting plate 81. The upper inclined plates 82 and the side inclined plates 83 are both inclined, and a loading channel is formed between the two upper inclined plates 82 and the side inclined plates 83. The loading channel is formed by the two upper inclined plates 82 and the two side inclined plates 83, and this loading channel just corresponds to the box mouth of the dumped packaging carton. When the packaging carton is pushed by the box-pushing mechanism 5, the two upper inclined plates 82 are just inserted into the two sides of the top of the carton mouth, and the two side inclined plates 83 are just inserted into the two sides of the carton mouth, thereby realizing the auxiliary opening of the carton mouth and facilitating the loading of materials.

[0040] like Figures 4-7 As shown, a pushing mechanism 7 for guiding and limiting the material is installed on the top of the frame 2, and the pushing mechanism 7 includes a limiting slide bar 3 74 symmetrically installed on the top crossbeam of the frame 2 and a moving seat 3 73 slidably connected to the two limiting slide bars 3 74. An adjusting cylinder 1 71 is installed in the middle of one side of the moving seat 3 73. The telescopic end of the adjusting cylinder 1 71 is located above the material conveyor 9 and is connected to a material-discharging plate 72. A material-discharging cylinder 75 is installed on the top of the frame 2 between the two limiting slide bars 3 74. The telescopic end of the material-discharging cylinder 75 is fixed to the middle of the other side of the moving seat 3 73. The material to be loaded is transmitted to the material conveyor 9 through the material conveyor 9. When the pushing mechanism 7 is in place, the regulating cylinder 71 will extend, thereby driving the material stripping plate 72 to move down to above the material conveyor 9, so that the material stripping plate 72 is located at the rear side of the material, and then the material stripping cylinder 75 is controlled to contract, so that it drives the moving seat three 73 to move linearly along the limiting slide bar three 74. When the moving seat three 73 moves linearly, the material stripping plate 72 will push the material to be loaded to move between the two guide plates 76, so that the material to be loaded is moved to the other side of the guide plate 76 by using the material stripping plate 72, so that the material to be loaded corresponds to the loading channel, and then the packing mechanism 6 is used to push the material to be loaded into the packaging carton, completing the automatic material pushing and packing operation.

[0041] like Figure 6 and 7As shown in the figure, the material pushing mechanism 7 further includes adjusting cylinders II 77 located outside the two limiting slide bars III 74. The telescopic end of each adjusting cylinder II 77 is connected with a guide plate 76. One of the adjusting cylinders II 77 is fixed on the top cross beam of the second frame 2 through a triangular seat, and the other adjusting cylinder II 77 is connected with a moving seat IV 78 through a triangular seat. Limiting slide bars IV 79 are symmetrically installed at both ends of the second frame 2 corresponding to the moving seat IV 78. Both ends of the moving seat IV 78 are slidably connected to the limiting slide bars IV 79, and the moving seat IV 78 and the cross beam at the top of the second frame 2 can be fixed by bolts. According to the size of the material to be loaded, the height of the guide plate 76 above the material conveyor 9 can be adjusted by the adjusting cylinder II 77. At the same time, the distance between the two guide plates 76 can also be adjusted by adjusting the position of the moving seat IV 78 on the limiting slide bars IV 79, so as to realize the guiding of materials to be loaded with different sizes and facilitate the subsequent packing operation of the materials to be loaded.

[0042] The working principle of the utility model is as follows: during operation, the packaging carton and the material to be loaded are respectively placed on the packaging carton conveyor 3 and the material conveyor 9 for transmission. The packaging carton is transmitted by the packaging carton conveyor 3 to the inside of the carton turning rod 42. When the transmission is in place, the packaging carton will touch the trigger switch on the limiting plate 45. At this time, the packaging carton conveyor 3 stops transmission, and the carton turning mechanism 4 starts to work;

[0043] The carton turning mechanism 4 is used to turn the packaging carton from the vertical state (i.e., the opening of the packaging carton is upward) to the dumping state (i.e., the opening of the packaging carton corresponds to the loading channel). At the same time, the carton pushing mechanism 5 works, and the push rod 55 is used to push the carton dumped inside the carton turning frame 41, and push the carton to the carton supporting mechanism 8, so that the carton supporting mechanism 8 is inserted into the opening of the carton to realize the auxiliary support for the opening of the carton;

[0044] At the same time, the material conveyor 9 will synchronously transmit the material to be loaded between the two guide plates 76. By pushing the material to be loaded by the material pushing plate 72, the material to be loaded is just located at the loading channel, so that the material to be loaded corresponds to the opening of the packaging carton. Then, the packing mechanism 6 is controlled to work, and the loading push plate 64 is used to push the material to be loaded towards the opening of the packaging carton. Further, the material to be loaded will be loaded into the packaging carton through the loading channel to complete the automatic packing operation;

[0045] It should be noted that when the material is packed, the push rod 55 of the carton pushing mechanism 5 is always located at the rear side of the packaging carton, which can realize the resistance support for the packaging carton, avoid the displacement of the packaging carton when the material is loaded into the packaging carton, and improve the packing efficiency;

[0046] After the materials are loaded into the packing carton, the box pushing mechanism 5 resets, and then the two turning cylinder 44 contract synchronously, thereby driving the two turning push plates 43 to reset. As a result, the two turning push plates 43 drive the turning rod 42 to turn and reset. Further, the turning frame 41 turns the packing carton after loading from the horizontal state to the vertical state, thus realizing the automatic packing and standing up and resetting operations.

[0047] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
