[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with 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 making creative efforts fall within the scope of protection of the present utility model.

[0027] Embodiment 1

[0028] As Figures 1 to 4As shown in the figure, this embodiment proposes a flat-bottom ton bag knitting bag rotary bag cutting mechanism, which includes a housing 1. Six support plates 2 are fixedly connected to the housing 1 by bolts. Two longitudinal rodless cylinders 3 are jointly installed on four of the support plates 2, and a transverse rodless cylinder 8 is jointly installed on the other two support plates 2. Sliding seats 4 are installed on both the longitudinal rodless cylinder 3 and the transverse rodless cylinder 8. Fixed plates 7 are fixedly connected to the bottoms of two of the sliding seats 4, and a lifting cylinder 9 is installed on one side of another sliding seat 4. The output end of the lifting cylinder 9 is fixedly connected to a lifting plate 10. A transverse cutting shaft 13 is rotatably installed on the lifting plate 10. A longitudinal cutting shaft 5 is rotatably installed jointly on the two fixed plates 7. Cutting wheels 14 are fixedly sleeved on the outer circumferential surfaces of both the transverse cutting shaft 13 and the longitudinal cutting shaft 5. A cutting auxiliary device 6 is arranged on the housing 1. The cutting auxiliary device 6 includes two rack plates 63, which are fixedly connected to the housing 1. Four squares are welded on one side of the housing 1. A guiding rod 65 is jointly welded on one side of every two squares. A sliding plate 64 is slidably assembled on the outer circumferential surfaces of the two guiding rods 65. A wheel shaft 66 and a roller shaft 67 are respectively rotatably installed on the sliding plate 64. A rotating shaft 61 is rotatably installed on the fixed plate 7. Large gears 62 are fixedly sleeved on the outer circumferential surfaces of both the rotating shaft 61 and the roller shaft 67. Small gears 60 are fixedly sleeved on the outer circumferential surfaces of both the wheel shaft 66 and the longitudinal cutting shaft 5. Through the settings of structures such as the large gears 62 and the small gears 60, when cutting, the large gear 62 moves. Due to the setting of the rack plate 63, the large gear 62 rotates, thereby realizing the rotation of the small gear 60, realizing the rotation of the cutting wheel 14, and realizing better cutting work on the knitting bag, making the device more convenient for cutting, saving costs, and improving work efficiency.

[0029] As Figures 2 to 3 shown, the large gear 62 meshes with the small gear 60, and the large gear 62 meshes with the rack plate 63.

[0030] As Figures 3 to 4 shown, two guiding holes are formed on the sliding plate 64, and the guiding rod 65 passes through the inside of the guiding holes.

[0031] As Figure 4 shown, two circular grooves are formed on the sliding plate 64, and the roller shaft 67 and the wheel shaft 66 are respectively rotatably installed inside the two circular grooves.

[0032] In this embodiment, the woven bag is placed on the housing 1, and the lifting cylinder 9 is started to drive the lifting plate 10 to move, so that the lifting plate 10 and the transverse cutting shaft 13 are respectively clamped with the sliding plate 64 and the wheel shaft 66, so that the transverse rodless cylinder 8 can drive the lifting plate 10 and the sliding plate 64 to move synchronously. The sliding plate 64 drives the large gear 62 and the small gear 60 to move synchronously. The meshing of the large gear 62 and the rack plate 63 causes the large gear 62 to rotate when it moves. The large gear 62 drives the small gear 60 to rotate, the small gear 60 drives the wheel shaft 66 to rotate, and the wheel shaft 66 drives the transverse cutting shaft 13 to rotate, realizing the transverse cutting of the ton bag by the cutting wheel 14. After that, the transverse rodless cylinder 8 and the lifting cylinder 9 drive it to reset. The longitudinal rodless cylinder 3 is started to drive the sliding seat 4 and the fixed plate 7 to move. The fixed plate 7 drives the large gear 62 and the small gear 60 to rotate. In the same steps as above, the longitudinal cutting shaft 5 drives the two cutting wheels 14 to rotate, realizing the two longitudinal cuts of the ton bag;

[0033] Further, the longitudinal rodless cylinder 3, the transverse rodless cylinder 8, the large gear 62 and the small gear 60 are protected by three protective boxes 16 installed on the housing 1 to prevent external corrosion or collision from affecting their transmission. The dust-proof ventilation plate 19 fixedly connected to the protective box 16 realizes the dust-proof, ventilation and heat dissipation effects inside the protective box 16. The protective door installed on one side of the protective box 16 makes it more convenient for the staff to maintain the devices inside the protective box 16.

[0034] Embodiment 2

[0035] As Figures 1 to 4 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the wheel shaft 66 and the sliding plate 64 are both provided with clamping holes 15. Two fixing rods 11 are welded to one side of the lifting plate 10. Clamping blocks 12 are slidably assembled on both the fixed plate 7 and the transverse cutting shaft 13, and the clamping blocks 12 are provided with arc surfaces.

[0036] As Figure 4 shown, the fixing rods 11 and the transverse cutting shaft 13 are both provided with clamping grooves, and the clamping blocks 12 are slidably connected inside the clamping grooves. A clamping spring is connected between the clamping blocks 12 and the inner wall of the clamping grooves.

[0037] In this embodiment, the lifting plate 10 drives the transverse cutting shaft 13 and the two fixed plates 7 to move, thereby driving the three clamping blocks 12 to move, so that the three clamping blocks 12 are respectively clamped into one clamping hole 15 on the wheel shaft 66 and the two clamping holes 15 on the sliding plate 64 to realize clamping and fixing. During reset, the arc surface on the clamping block 12 makes the disassembly and installation more convenient.

[0038] 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.
