[0032] Embodiment 1:

[0033] The present utility model provides a guiding track.

[0034] In an embodiment of the present utility model, a guiding track 200 is arranged on a bag throwing machine 100 and is used for guiding a strip of packaging bags. The bag throwing machine 100 includes a frame 1, a cutting knife assembly, a driving assembly, and a plurality of traction wheels arranged on the frame 1 and used for rolling traction of the strip of packaging bags. It includes a fixed rail 2, a movable rail 3, and a holder 4. The fixed rail 2 and the movable rail 3 are both installed on the frame 1 in a position-limiting and movable manner along the width direction of the bag throwing machine 100. The fixed rail 2 and the movable rail 3 are arranged opposite to each other and enclose a guiding groove 5 for the strip of packaging bags to pass through. The fixed rail 2 is provided with through holes 6 for the plurality of traction wheels to pass through, so that the plurality of traction wheels can be in contact with the strip of packaging bags. The holder 4 is located between the plurality of traction wheels, and the holder 4 extends into the guiding groove 5 and is used for contacting the strip of packaging bags. A scale 7 is formed on the movable rail 3.

[0035] It should be noted that during the actual operation of the bag throwing machine 100, the driving assembly can drive the plurality of traction wheels to rotate to traction the strip of packaging bags (packaging bags connected in a strip shape), so that the strip of packaging bags can move to the cutting knife assembly and be cut by the cutting knife assembly. Thus, the cut single packaging bags can be accurately placed on the designated bag throwing target. The structural design is simple and reasonable. By arranging the guiding track 200 of the present utility model on the bag throwing machine 100, the strip of packaging bags can be accurately guided, which is convenient for the subsequent cutting knife assembly to quickly cut the strip of packaging bags and meets the fast and efficient processing requirements of the bag throwing machine 100.

[0036] Specifically, as Figures 1 to 5As shown, in a guide rail 200 of the utility model, since the fixed rail 2 and the movable rail 3 are both installed on the frame 1 in a limited and movable manner along the front-back direction, the fixed rail 2 and the movable rail 3 can be installed with the frame 1 in a limited and movable manner by threaded connection or pin connection, that is, the fixed rail 2 and the movable rail 3 can both move along the front-back direction on the frame 1, and the fixed rail 2 and the movable rail 3 can be limited with the frame 1 by studs or pins, so that the staff can adjust the position of the fixed rail 2 and the movable rail 3 according to the width of different material bag belts, meet the guiding and traction requirements of the utility model for material bag belts of various specifications and sizes, and improve the applicability. Furthermore, the fixed rail 2 and the movable rail 3 can enclose a guide groove 5 for the material bag belt to pass through, and the fixed rail 2 is provided with a through hole 6 for a plurality of traction wheels to pass through, so that the plurality of traction wheels can abut against the material bag belt and roll and traction the material bag belt. In this process, the left and right groove walls of the guide groove 5 abut against the left and right side walls of the material bag belt, thereby realizing the left and right limit of the material bag belt, effectively preventing the material bag belt from deviating in the guide groove 5, and improving the stability of the material bag belt during traction and movement. It can be understood that since the retainer 4 is arranged between a plurality of traction wheels, and the retainer 4 can extend into the guide groove 5 and abut against the material bag belt, the material bag belt can be limited in the up and down directions, effectively preventing the material bag belt from shaking or swaying during the traction and movement, which not only further improves the stability of the material bag belt during traction and movement, making the traction and movement of the material bag belt smoother, but also improves the accuracy of the cutting length of the material bag belt by the cutter assembly, and reduces the cutting error caused by the deviation or shaking of the material bag belt. In addition, since the scale 7 is formed on the movable rail 3, the staff can intuitively know and measure the length of the traction material bag by checking the scale 7 without the need for other measurement auxiliary tools, which is more convenient to use.

[0037] It is worth mentioning that when a guide rail 200 of the utility model is installed on a bag delivery machine 100, a protective shell for shielding the utility model is correspondingly provided on the bag delivery machine 100, and an observation window (closed by a transparent plate) is provided on the protective shell, thereby not only being able to shield and protect the utility model, but also being able to meet the needs of the staff to intuitively view the scale 7 and conveniently measure the length of the material bag.

[0038] In one embodiment, if Figures 1 to 4As shown, a plurality of ears 8 are formed on the side of the fixed rail 2 and the movable rail 3 away from the guide groove 5, and an adjustment groove 9 is provided on the frame 1 along the width direction of the bag throwing machine 100, and the plurality of ears 8 are detachably connected to the frame 1 through locking members inserted in the adjustment groove 9. It can be understood that by detachably connecting the plurality of ears 8 to the frame 1, it is possible to achieve multi-point position limiting of the fixed rail 2 and the movable rail 3, thereby ensuring the stability of the installation of the fixed rail 2 and the movable rail 3 on the frame 1. Further, the locking member can be selected as a bolt connection in the prior art, that is, the stud passes through the ear 8 and the adjustment groove 9 and is threadedly connected with the nut, thereby not only being able to stably install the fixed rail 2 and the movable rail 3 on the frame 1, but also being convenient for the staff to adjust the position of the fixed rail 2 and the movable rail 3 by screwing the nut, thereby changing the width dimension of the guide groove 5 to adapt it to the width dimension of the bag belt, thereby preventing the bag belt from deviating when being pulled and moved in the guide groove 5.

[0039] In one embodiment, one end of the guide groove 5 is expanded outward to form a feed opening 10 for the feed bag to enter. Figure 2 and Figure 3 As shown, the right end notch of the guide groove 5 is outwardly expanded, that is, the feed port 10 of the guide groove 5 is outwardly expanded, so that the material bag belt can enter the guide groove 5 easily, and the structural design is simple and reasonable.

[0040] In one embodiment, the edge of the top of the side wall of the movable rail 3 extends toward the guide groove 5 and bends to form a baffle 11 for shielding the material bag belt, and a scale 7 is formed on the baffle 11 along its extension direction. Figure 3 and Figure 4 As shown, the baffle 11 can not only shield and protect the material bag belt in the guide groove 5, but also limit the front edge of the material bag belt, so that it can cooperate with the retaining frame 4 to further improve the stability and smoothness of the material bag belt when it is pulled and moved in the guide groove 5. Furthermore, by setting the scale 7 at the baffle 11, it can be prevented from being blocked by other structural components and affecting the viewing of the staff.

[0041] In one embodiment, an adjustment block 12 is provided on the side wall of the fixed rail 2, and a plurality of mounting holes 13 are evenly and spaced apart on the adjustment block 12 along the extension direction of the fixed rail 2. A locking column 14 is provided on the retaining frame 4, and the locking column 14 is detachably connected to any one of the mounting holes 13 to mount the retaining frame 4 on the fixed rail 2. Specifically, Figures 3 to 5As shown, the adjusting block 12 is provided with a plurality of mounting holes 13 in the left - right direction, and the cage 4 is provided with a locking post 14. The locking post 14 can be a stud in the prior art. By thread - connecting the locking post 14 with any one of the mounting holes 13, not only can the cage 4 be stably mounted on the adjusting block 12, which is convenient for disassembly and assembly, but also the mounting position of the cage 4 can be adaptively adjusted to prevent the material - package belt from getting stuck during the traction movement, reducing the probability of the malfunction of the bag - throwing machine 100 and ensuring reliable use.

[0042] In one embodiment, the cage 4 includes a mounting base 15 and a pressing plate 16 detachably connected to the mounting base 15. A limiting groove 17 is formed in the mounting base 15, and the extending direction of the limiting groove 17 is perpendicular to the extending direction of the fixed rail 2. The locking post 14 passes through the limiting groove 17 and is detachably connected to the mounting hole 13. The pressing plate 16 extends into the guiding groove 5 and is used to abut against the material - package belt. Specifically, as Figure 4 and Figure 5 shown, by forming the limiting groove 17 in the mounting base 15 and the limiting groove 17 extending in the up - down direction, it enables the staff to adjust the up - down movement of the mounting base 15 by screwing the locking post 14. Further, since the pressing plate 16 is detachably connected to the mounting base 15, the detachable connection method can be a threaded connection, which is convenient for the staff to disassemble, assemble and replace the pressing plate 16. At the same time, the pressing plate 16 can move up and down synchronously with the mounting base 15, so that the pressing plate 16 can effectively guide and fix the material - package belt, preventing the material - package belt from shifting or shaking during the movement. Also, the direct contact between the pressing plate 16 and the material - package belt improves the processing accuracy and stability.

[0043] In one embodiment, a positioning groove 18 is formed in the pressing plate 16, and the extending direction of the positioning groove 18 is the same as the extending direction of the adjusting groove 9. The pressing plate 16 is detachably connected to the mounting base 15 by a stud passing through the positioning groove 18. As Figure 5 shown, it can be understood that the staff can adjust the mounting position of the pressing plate 16 by loosening the stud, that is, the pressing plate 16 can move relative to the mounting base 15 in the front - back direction and be fixed by tightening the stud, so that the pressing plate 16 can adapt to the wider material - package belt in the adjusting groove 9 and limit it, ensuring reliable use.

[0044] In one embodiment, specifically, as Figure 3 and Figure 5 shown, both ends of the pressing plate 16 along its extending direction are inclined away from the material - package belt, so as to optimize the contact angle and force between the traction wheel and the material - package belt, reducing friction and wear.

[0045] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
