[0001] The utility model relates to the technical field of woven bag processing, in particular to a cutting machine for high-strength woven bags. Background Art

[0002] Woven bags are made of polyethylene, polypropylene and other materials through a special weaving process. They have strong tensile strength and wear resistance, are not easy to break, and are reusable. After a special coating treatment, the woven bags have a certain waterproof property, which can protect the items in the bag from moisture. Therefore, they are widely used in the field of item packaging and transportation.

[0003] Among them, before the woven bag is put into use, it is necessary to use a cutting machine to cut the rolled woven bag into a suitable size and then seal it for use.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, this embodiment proposes a cutting machine for high-strength woven bags, including a cutting table 1, a support frame 2 is fixedly connected to the top of one end of the cutting table 1, the top of the support frame 2 is rotatably connected to the support shaft 3, one end of the top of the support frame 2 is fixedly connected to a drive motor 4, and the output end of the drive motor 4 is fixedly connected to the support shaft 3, and a detachable discharge roller 5 is provided at one end of the support shaft 3, a positioning frame 6 is fixedly connected to the middle part of one side of the cutting table 1, a linear guide rod 7 is fixedly connected to the middle part of the top of the positioning frame 6, a displacement frame 8 is slidably connected to the outer side of the linear guide rod 7, a cutting knife 9 is fixedly connected to the displacement frame 8 close to the cutting table 1, and a smoothing component 10 is provided on the inner side of the positioning frame 6;

[0026] In detail, the ends of the support shaft 3 and the discharge roller 5 close to each other are fixedly connected with flanges, and the support shaft 3 and the discharge roller 5 are connected through the flange. The setting of the flange can ensure the stability of the connection between the support shaft 3 and the discharge roller 5, and can also quickly replace the discharge roller 5 after it is consumed, making the overall operation more convenient.

[0027] Furthermore, the end of the top of the support frame 2 away from the driving motor 4 is fixedly connected to a stabilizing bracket, and the end of the unloading roller 5 away from the supporting shaft 3 is also placed on the top of the stabilizing bracket. The setting of the stabilizing bracket can provide auxiliary support for the unloading roller 5 to ensure the smoothness of the unloading roller 5.

[0028] Example 2

[0029] like Figures 1 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes a smoothing component 10;

[0030] In this embodiment, the smoothing assembly 10 includes a linear slide 11, a smoothing frame 12, a linkage rod 13, a linkage plate 14 and a transmission motor 15. The bottom end of the inner side of the positioning frame 6 is fixedly connected to the linear slide 11, and the outer side of the linear slide 11 is slidably connected to two smoothing frames 12. The tops of the two smoothing frames 12 are rotatably connected to the linkage rod 13. One end of the top of the linear guide rod 7 is fixedly connected to the linkage plate 14, and the tops of the two linkage rods 13 are also rotatably connected to the two ends of the linkage plate 14. One end of the positioning frame 6 is fixedly connected to the transmission motor 15;

[0031] Furthermore, both ends of the linkage plate 14 are fixedly connected to a U-shaped seat, and the end of the linkage rod 13 away from the smoothing frame 12 is connected to the inside of the U-shaped seat through a rotating shaft. The arrangement of the U-shaped seat can simultaneously support both ends of the rotating shaft at the linkage rod 13 to ensure the stability of the linkage rod 13 when rotating;

[0032] The smoothing assembly 10 also includes a driving screw 16, a central shaft 17, a self-locking motor 18, a guide shaft 19 and a guide frame 20. The output end of the transmission motor 15 is fixedly connected to the driving screw 16, and one of the smoothing frames 12 is also threadedly connected to the outside of the driving screw 16. The top end of the inner side of the positioning frame 6 is rotatably connected to the central shaft 17. The other end of the positioning frame 6 is fixedly connected to the self-locking motor 18, and the output end of the self-locking motor 18 is fixedly connected to the central shaft 17. The top ends of the two smoothing frames 12 are both rotatably connected to the guide shaft 19, and the two guide shafts 19 are both slidably connected to the outside of the central shaft 17. The outside of the guide shaft 19 is fixedly connected to the guide frame 20, and one end of the guide frame 20 is rotatably connected to the smoothing roller 21.

[0033] Here, a stabilizing plate is fixedly connected to the middle part of the inner side of the positioning frame 6, and the end of the driving screw 16 close to the stabilizing plate is also rotatably connected to the stabilizing plate. The setting of the stabilizing plate can provide auxiliary support for the driving screw 16 to prevent the driving screw 16 from shaking when rotating;

[0034] Furthermore, a guide bar is fixedly connected to the outer side of the central shaft 17, a guide groove is provided inside the guide shaft 19, and the guide bar is also slidably connected inside the guide groove. Since the guide bar is slidably connected inside the guide groove, the guide shaft 19 can slide along the central shaft 17 and, when the central shaft 17 rotates, the guide bar can drive the guide shaft 19 to rotate accordingly.

[0035] A specific application of the above two embodiments is that the unloading roller 5 with the woven bag wrapped thereon is first assembled with the support shaft 3, and then the driving motor 4 is started to drive the support shaft 3 to rotate, and the connection between the support shaft 3 and the unloading roller 5 is coordinated to discharge the woven bag at the unloading roller 5, and then the personnel pulls the woven bag to adjust the cutting position of the woven bag to correspond to the cutting knife 9, and then the self-locking motor 18 is started to drive the central shaft 17 to rotate, and the connection between the central shaft 17 and the guide shaft 19 is coordinated so that the guide shaft 19 can rotate with the central shaft 17, thereby driving the smoothing roller 21 to turn through the guide frame 20 until the smoothing roller 21 contacts the woven bag;

[0036] Restarting the transmission motor 15 drives the driving screw 16 to rotate, and cooperating with the connection between the driving screw 16 and one of the smoothing frames 12, one of the smoothing frames 12 will be displaced along the driving screw 16 under the limit of the linear slide 11, and the linkage plate 14 will be pulled by the linkage rod 13 on one of the smoothing frames 12, prompting the linkage plate 14 to move downward under the support of the linear guide rod 7, and since the two linkage rods 13 are connected to the linkage plate 14, when the linkage plate 14 moves downward, it can push the other linkage rod 13, and then drive the other smoothing frame 12 to slide, so that the smoothing rollers 21 move away from each other on the surface of the woven bag, smoothing the cutting position of the woven bag, and in the process of the linkage plate 14 moving downward, it can drive the cutting knife 9 to fall until the cutting knife 9 contacts the woven bag, and finally complete the cutting operation of the woven bag.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
