Description

Technical Field

[0001] The utility model relates to the technical field of carton packing, in particular to a limit alignment device for a carton packing machine. Background Art

[0002] A carton packing machine, also known as a carton strapping and packing machine, is a device widely used in the fields of carton production, packing, and logistics. It is a device specifically used for strapping and packing cartons. Its main function is to seal and bundle single or multiple cartons to form a solid package for easy transportation and storage. The packing machine uses strapping bands to wind around the cartons. The strapping bands have high tensile strength and wear resistance. During the winding process, the strapping bands are heated and pressed tightly by the rollers on the machine to make the cartons into a solid whole. Since the position of the cartons directly affects the strapping effect of the strapping bands of the packing machine, it is necessary to perform packing limit alignment operations on the cartons.

[0003] In the related art, during the use of the packing machine, generally, by installing travel conveyor belts on both sides of the top of the workbench, the cartons during the conveying and packing process are conveyed and limited, so that the cartons are in a regular state during the strapping process and then used.

[0004] However, currently during the use of the packing machine, since the cartons need to move out of the travel conveyor belt during the strapping and packing process to provide space for the unstrapped strapping bands to contact and strap the cartons, and when the packing machine tightens the strapping bands to strap and pack the cartons, the cartons will shift in position under the influence of the tightening force of the strapping bands, resulting in the other end of the cartons being in a shifted position during the strapping and packing process, which makes it easy for the strapping position of the strapping bands to shift and loosen or even accidentally damage the cartons, affecting the packing limit stability and packing effect of the packing machine.

Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative effort shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1-4 , the present utility model provides a technical solution: a limit alignment device for a carton packing machine, including a workbench 1 and a packing limit mechanism. Conveyor frames 2 are installed on both sides of the top of the workbench 1, and a packing frame 3 is installed on the left side of the top of the workbench 1. When the conveyor frames 2 cooperate with the packing frame 3, the cartons moved to the bottom of the packing frame 3 can be stably aligned and limited, so that the cartons are in a regular position at the bottom of the packing frame 3, avoiding the situation that the position deviation occurs during the carton packing process, resulting in the reduction of the bundling and packing stability and the packing effect of the packing frame 3. Therefore, the bundling and packing limit stability and the packing effect of the packing frame 3 are improved.

[0032] Referring to Figures 1-4, in a preferred embodiment, the packing limiting mechanism includes a fixed rod 4, the fixed rod 4 is fixedly connected to the left side of both sides of the workbench 1, the top of the fixed rod 4 is movably connected with a movable shell 5, the limiting plates 6 are movably connected to both sides of the bottom of the movable shell 5, a connecting groove 7 is opened at the top of the fixed rod 4, a connecting rod 8 is movably connected inside the connecting groove 7, and the top of the connecting rod 8 is fixedly connected to the bottom of the movable shell 5. The limiting translation mechanism is movably connected inside the movable shell 5. First, hold the movable shell 5 and raise it according to the actual height of the external carton to adjust the height of the movable shell 5. Then, according to the actual width of the external carton, hold the limiting plate 6 and move it to adjust the limiting distance between the limiting plates 6. When the conveying rack 2 conveys the carton and moves it to the bottom of the packing rack 3, the front side of the carton enters the inner side of the limiting plate 6. Since the right side of the limiting plate 6 is located on the left side of the tightening opening of the bundling belt of the packing rack 3, it ensures stable alignment of the carton during limiting, and at the same time, does not affect the packing rack 3 to bundle and pack the carton with the bundling belt, ensuring the stability and packing effect during the carton packing process. The limiting translation mechanism includes a positive and negative screw rod 9, a translation seat 10 and a rotating frame 11. The positive and negative screw rod 9 is movably connected inside the movable shell 5, the translation seat 10 is threadedly connected to both sides of the surface of the positive and negative screw rod 9, and the rotating frame 11 is fixedly connected to both sides of the positive and negative screw rod 9. The outside of the rotating frame 11 penetrates to the outside of the movable shell 5. When the movable shell 5 cooperates with the limiting plate 6, it can provide a medium for the user to translate the limiting plate 6 and adjust the limiting distance between the limiting plates 6 by translation, avoiding the situation that it is difficult to adjust the translation according to the size between the external cartons when the limiting plate 6 is used. Therefore, the flexibility of use of the limiting plate 6 is improved.

[0033] Referring to Figures 3-4 , in a preferred embodiment, by opening a lifting groove 12 at the top of the limiting plate 6, a lifting frame 13 is movably connected inside the lifting groove 12, and the top of the lifting frame 13 is fixedly connected to the top of the translation seat 10. When the translation seat 10 cooperates with the limiting plate 6, it can perform lifting connection work between the limiting plate 6 and the translation seat 10, avoiding the situation that the translation seat 10 and the limiting plate 6 are separated after the movable shell 5 is lifted. Therefore, the connection flexibility between the limiting plate 6 and the translation seat 10 is improved. A limiting port 14 is opened on the outer side of the inner wall of the connecting groove 7, and a limiting rod 15 located inside the limiting port 14 is fixedly connected to the bottom of the outside of the connecting rod 8. When the connecting groove 7 cooperates with the connecting rod 8, it can perform lifting limit work between the connecting rod 8 and the connecting groove 7, avoiding the situation that the connecting rod 8 is separated from the connecting groove 7 when the connecting rod 8 cooperates with the movable shell 5 and the fixed rod 4. Therefore, the use stability of the connecting rod 8 is improved.

[0034] Referring to Figures 2-3, in a preferred embodiment, positioning columns 16 are fixedly connected to both sides of the outer side of the fixed rod 4. A plurality of positioning columns 16 are provided, and the plurality of positioning columns 16 are equidistantly distributed. Positioning sleeves 17 located outside the positioning columns 16 are movably connected to both sides of the limiting rod 15. When the limiting rod 15 is used in cooperation with the connecting rod 8, the positioning work between the connecting rod 8 and the fixed rod 4 after lifting and moving can be carried out through the limiting rod 15, avoiding the situation that it is difficult to position when the connecting rod 8 is used. Therefore, the positioning convenience of the connecting rod 8 is improved. A connecting cylinder 18 located inside the positioning sleeve 17 is sleeved and connected to the surface of the limiting rod 15. The outer side of the connecting cylinder 18 is fixedly connected to the inner side of the positioning sleeve 17. When the limiting rod 15 is used in cooperation with the positioning sleeve 17, a medium for connecting the positioning sleeve 17 to the connecting rod 8 can be provided, avoiding the situation that the positioning sleeve 17 is separated from the limiting rod 15 when it is used. Therefore, the connection effect between the positioning sleeve 17 and the limiting rod 15 is improved.

[0035] Referring to Figure 3 , in a preferred embodiment, magnetic attraction strips 19 are inlaid and connected to both sides of the inner wall of the limiting port 14. Magnetic strips 20 magnetically connected to the magnetic attraction strips 19 are inlaid and connected to both sides of the limiting rod 15. When the limiting rod 15 is used in cooperation with the connecting rod 8, magnetic attraction pre-positioning work between the connecting rod 8 and the fixed rod 4 can be carried out through the limiting rod 15, avoiding the situation that it is difficult to carry out pre-positioning when the connecting rod 8 is used, resulting in inconvenient positioning operation of the subsequent positioning sleeve 17. Therefore, the positioning operation convenience of the connecting rod 8 is improved. Magnetic sheets 21 located outside the magnetic strips 20 are inlaid and connected to both sides of the inner wall of the connecting cylinder 18. The inner side of the magnetic sheet 21 is magnetically connected to the outer side of the magnetic strip 20. When the connecting cylinder 18 is used in cooperation with the positioning sleeve 17, magnetic positioning work between the positioning sleeve 17 and the limiting rod 15 can be carried out through the connecting cylinder 18, avoiding the situation that the positioning sleeve 17 is translated and separated from the positioning column 16 when it is used. Therefore, the positioning stability of the positioning sleeve 17 is improved.

[0036] Specifically, the working process or principle of the limit alignment device of the carton packing machine is as follows: When in use, first, according to the actual height of the external carton, hold the connecting cylinder 18 by hand and drive the positioning sleeve 17 to move outward to separate from the positioning column 16, and then hold the movable shell 5 and lift it to adjust the height of the movable shell 5. At this time, the connecting rod 8 follows the movable shell 5 and moves inside the connecting groove 7 to perform the upward connection work between the movable shell 5 and the fixed rod 4. At the same time, the limiting rod 15 follows the connecting rod 8 and moves inside the limiting port 14 to perform the movable limiting work between the connecting rod 8 and the connecting groove 7. During this process, the lifting frame 13 follows the movable shell 5 and moves inside the lifting groove 12 through the translation seat 10 to perform the lifting connection work between the translation seat 10 and the limiting plate 6. At the same time, the limiting rod 15 performs the magnetic pre-positioning work between the connecting rod 8 and the fixed rod 4 through the magnetic attraction strip 19 and the magnetic strip 20. Then, hold the connecting cylinder 18 by hand and drive the positioning sleeve 17 to move inward and sleeved on the outside of the positioning column 16, so that the positioning sleeve 17 cooperates with the positioning column 16 to position the connecting rod 8 and the fixed rod 4 through the connecting cylinder 18 and the limiting rod 15. At this time, the magnetic sheet 21 cooperates with the magnetic strip 20 to perform the magnetic attraction positioning work between the positioning sleeve 17 and the limiting rod 15 through the connecting cylinder 18 to ensure the stability of the movable shell 5 after lifting. Subsequently, according to the actual width of the external carton, hold the rotating frame and drive the forward and reverse screw rod 9 to rotate to apply a threaded translation thrust to the translation seat 10, so that the translation seat 10 drives the limiting plate 6 to move through the lifting frame 13 and cooperate with the lifting groove 12 to adjust the limiting distance between the limiting plates 6. When the conveying frame 2 conveys the carton and moves it to the bottom of the packing frame 3, the front side of the carton enters the inside of the limiting plate 6, and the limiting plate 6 performs the limiting and stable alignment work on the carton, so that the carton is in a regular state at the bottom of the packing frame 3. Since the right side of the limiting plate 6 is located on the left side of the tightening opening of the bundling belt of the packing frame 3, it is ensured that the limiting plate 6 performs the limiting and stable alignment work on the carton, and at the same time, it does not affect the packing frame 3 to perform the bundling and packing work on the carton through the bundling belt, ensuring the stability and packing effect during the carton packing process.

[0037] It should be noted that the workbench 1, the conveying frame 2 and the packing frame 3 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
