Description

Technical Field

[0001] This utility model relates to the field of feed outlet machines, specifically a drawstring feed outlet machine for container bags. Background Technology

[0002] In the production of FIBCs, punching holes in the surface of the FIBC to set the drawstring opening is an important process. Traditional FIBC drawstring opening machines have many drawbacks.

[0003] On the one hand, existing punching equipment has low punching efficiency, which is difficult to meet the needs of large-scale production and greatly limits the production speed of FIBCs, thus affecting the improvement of enterprise capacity. On the other hand, before the punching operation, there is a lack of effective pressing and fixing devices for FIBCs, which makes FIBCs prone to displacement during the punching process. Once the FIBC is displaced, it will not only cause the punching position to deviate and the drawstring opening position to be inaccurate, affecting the normal use function of the FIBC, but may also cause additional damage to the FIBC by the punching equipment due to the position deviation, increasing the defect rate and increasing production costs. Therefore, it is necessary to design a FIBC drawstring opening machine to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drawstring feeding machine for container bags to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawstring feeding machine for container bags, comprising a base, a U-shaped frame fixedly installed on the top of the base, a threaded rod rotatably connected to the top of the U-shaped frame via a bearing component, a threaded sleeve threadedly connected to the surface of the threaded rod, and a traction plate fixedly installed on the surface of the threaded sleeve;

[0006] A motor is fixedly installed on the top of the traction plate. A rotating rod is fixedly installed on the output shaft of the motor through a coupling. The bottom end of the rotating rod passes through the traction plate and extends to the outside of the traction plate. A punching knife is fixedly installed on the bottom end of the rotating rod. The bottom of the punching knife passes through the U-shaped frame and extends to the outside of the U-shaped frame.

[0007] Preferably, the inner wall of the U-shaped frame is provided with sliding grooves on both sides, and a slider is slidably connected inside the sliding groove. A pressure block is fixedly installed on one side of the slider, and an anti-slip groove is provided at the bottom of the pressure block.

[0008] Preferably, a sleeve is fixedly installed on the top of the pressure block, the top of the sleeve passes through the U-shaped frame and extends to the outside of the U-shaped frame, a spring is welded to the bottom of the inner cavity of the sleeve, a sliding rod is welded to the top of the spring, and the top of the sliding rod is fixedly connected to the bottom of the traction plate.

[0009] Preferably, a first gear is fixedly mounted on the surface of the threaded rod, and a second gear that meshes with the first gear is rotatably connected to the top of the U-shaped frame via a bearing. A limit rod is fixedly mounted on the inner wall of the second gear, and the top of the limit rod passes through the rotating rod and extends into the interior of the rotating rod.

[0010] Preferably, one side of the rotating rod has a sliding opening that cooperates with the limiting rod.

[0011] Preferably, the top of the base is provided with a material discharge groove for use with a punching tool.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This FIBC drawstring feeding machine works by placing the FIBC to be punched on top of the base, then starting the motor. The motor drives the rotating rod to rotate, which in turn drives the punching blade to rotate. Simultaneously, the rotating rod drives the second gear to rotate via the limit rod. The second gear, in turn, meshes with the first gear to drive the threaded rod to rotate. The threaded rod then drives the threaded sleeve to descend, which in turn drives the traction plate to descend. At this point, the punching blade rotates and descends to the material drop chute, achieving the effect of efficiently punching holes in the FIBC.

[0014] 2. This container bag drawstring feeding machine, by setting up a pressure block, allows the traction plate to descend, which in turn drives the slide bar to descend. The descent of the slide bar drives the spring and sleeve to descend, and the descent of the sleeve drives the pressure block to descend. After the pressure block descends, it can first press down on both sides of the top of the container bag. At this time, the traction plate continues to descend and can press down on the spring through the slide bar, thereby preventing the container bag from shifting and improving the stability of the punching.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a drawstring feeding machine for container bags, including a base 1, a U-shaped frame 2 fixedly installed on the top of the base 1, a threaded rod 3 rotatably connected to the top of the U-shaped frame 2 through a bearing component, a threaded sleeve 4 threadedly connected to the surface of the threaded rod 3, and a traction plate 5 fixedly installed on the surface of the threaded sleeve 4.

[0024] Specifically, a motor 6, a servo motor, is fixedly mounted on the top of the traction plate 5. A rotating rod 7 is fixedly mounted on the output shaft of the motor 6 via a coupling. The bottom end of the rotating rod 7 passes through the traction plate 5 and extends to the outside of the traction plate 5. A punching tool 8 is fixedly mounted on the bottom end of the rotating rod 7. The bottom of the punching tool 8 passes through the U-shaped frame 2 and extends to the outside of the U-shaped frame 2. A first gear 16 is fixedly mounted on the surface of the threaded rod 3. A second gear 17, meshing with the first gear 16, is rotatably connected to the top of the U-shaped frame 2 via a bearing. A limit rod 18 is fixedly mounted on the inner wall of the second gear 17. The top of the limit rod 18 passes through the rotating rod 7 and extends into the interior of the rotating rod 7. A groove is opened on one side of the rotating rod 7... The sliding mouth 19 is used in conjunction with the limiting rod 18. The top of the base 1 is provided with a material drop groove 20 that is used in conjunction with the punching knife 8. By setting up a motor 6, and placing the container bag to be punched on the top of the base 1, and then starting the motor 6, the motor 6 drives the rotating rod 7 to rotate. The rotating rod 7 drives the punching knife 8 to rotate. At the same time, the rotation of the rotating rod 7 drives the second gear 17 to rotate through the limiting rod 18. The rotation of the second gear 17 drives the threaded rod 3 to rotate through meshing with the first gear 16. The rotation of the threaded rod 3 drives the threaded sleeve 4 to descend. The descent of the threaded sleeve 4 drives the traction plate 5 to descend. At this time, when the punching knife 8 rotates and descends to the material drop groove 20, the effect of efficiently punching the container bag can be achieved.

[0025] Specifically, the inner wall of the U-shaped frame 2 has grooves 9 on both sides, and a slider 10 is slidably connected inside the grooves 9. A pressure block 11 is fixedly installed on one side of the slider 10. An anti-slip groove 15 is opened at the bottom of the pressure block 11, and a sleeve 12 is fixedly installed on the top of the pressure block 11. The top of the sleeve 12 passes through the U-shaped frame 2 and extends to the outside of the U-shaped frame 2. A spring 13 is welded to the bottom of the inner cavity of the sleeve 12, and a sliding rod 14 is welded to the top of the spring 13. The top of the sliding rod 14 is fixedly connected to the bottom of the traction plate 5. By setting the pressure block 11, the traction plate 5 can drive the sliding rod 14 to descend when it descends. The descent of the sliding rod 14 drives the spring 13 and the sleeve 12 to descend. The descent of the sleeve 12 drives the pressure block 11 to descend. After the pressure block 11 descends, it can first press on both sides of the top of the container bag. At this time, the traction plate 5 continues to descend and can press the spring 13 through the sliding rod 14 to achieve the effect of preventing the container bag from shifting and improving the stability of the punching.

[0026] Working Principle: This utility model is a drawstring feeding machine for FIBCs (Flexible Intermediate Bulk Containers). The FIBC to be punched is placed on top of the base 1, and then the motor 6 is started. The motor 6 drives the rotating rod 7 to rotate, which in turn drives the punching cutter 8 to rotate. Simultaneously, the rotating rod 7, through the limiting rod 18, drives the second gear 17 to rotate. The second gear 17, through meshing with the first gear 16, drives the threaded rod 3 to rotate. The threaded rod 3, in turn, drives the threaded sleeve 4 to descend, which in turn drives the traction plate 5 to descend. At this time, the punching cutter 8, while rotating, descends to the material drop trough 20, achieving efficient punching of the FIBC. Simultaneously, the traction plate 5, as it descends, drives the sliding rod 14 to descend, which in turn drives the spring 13 and sleeve 12 to descend. The sleeve 12, in turn, drives the pressure block 11 to descend. After descending, the pressure block 11 presses down on both sides of the top of the FIBC. As the traction plate 5 continues to descend, it presses down on the spring 13 through the sliding rod 14, preventing displacement of the FIBC and improving the stability of the punching process.
