[0006] According to the aforementioned testing device for producing container bags, a support plate is fixed at the center of the front end of the vertical baffle, and a groove is formed at the center of the front end of the support plate. Protective blocks are fixed at the top and bottom of the inner side of the groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a testing device for producing bulk bags, including a base plate 1, with supporting legs 2 fixed around the bottom of the base plate 1, a vertical baffle 3 fixed to one side of the top of the base plate 1, a top plate 4 fixed to the front end of the vertical baffle 3, and vertical plates 5 fixed to both ends of the other side of the top of the base plate 1. The tops of the two vertical plates 5 are fixedly connected to the bottom of the top plate 4. An upper groove 6 is opened at the center of the top of the base plate 1. A drive motor 7 is rotatably connected to one end of the inner wall of the upper groove 6. A drive screw 8 is fixed to the output end of the drive motor 7. The two ends of the drive screw 8 have opposite thread directions. The other end of the drive screw 8 is rotatably connected to the other end of the inner wall of the upper groove 6. A left clamp 9 and a right clamp 10 are sleeved on both ends of the outer side of the drive screw 8. Both the left clamp 9 and the right clamp 10 are slidably connected to the inner wall of the upper groove 6. In the prior art, bulk bags are a type of flexible transport packaging container, widely used for powdery, granular, and lumpy materials such as food, grains, pharmaceuticals, chemicals, and minerals. For the transportation and packaging of goods, the performance testing of FIBCs is particularly important. Currently, the tensile performance testing of FIBCs involves placing the items inside the FIBC and then stretching the FIBC using a stretching component to determine its tensile performance. However, when placing the FIBC on the test platform, external factors can cause instability, reducing the efficiency of the tensile performance test. To address this issue, the FIBC can be placed on top of the base plate 1, with the items placed inside. Then, depending on the size of the FIBC, the drive motor 7 is started to rotate, causing the drive screw 8 to rotate. Since the threads on both sides of the drive screw 8 are in opposite directions, the left clamping plate 9 and the right clamping plate 10 move towards each other. When both the left clamping plate 9 and the right clamping plate 10 have moved to the side of the FIBC, the positional shift of the FIBC during the tensile performance test can be avoided.

[0022] A support plate 11 is fixed at the center of the front end of the baffle 3. A groove 12 is provided at the center of the front side of the support plate 11. Protective blocks 13 are fixed at the top and bottom of the inner side of the groove 12. A lifting motor 14 is rotatably connected to the bottom of the top protective block 13. A lifting screw 15 is fixed at the bottom of the lifting motor 14. A slider 16 is sleeved on the outer side of the lifting screw 15. The slider 16 is slidably connected to the inner wall of the groove 12. The width of the slider 16 is greater than the width of the groove 12. A hook 17 is provided on the bottom side of the slider 16. After the left clamping plate 9 and the right clamping plate 10 press down on both ends of the container bag, the pull ropes around the top surface of the container bag are tied together to form a... In the enclosed structure, the lifting motor 14 controls the lifting screw 15 to rotate, causing the slider 16 to move down with the hook 17. Thus, the hook 17 can lift the pull rope tied to the top of the container bag, thereby achieving the effect of lifting the container bag. A tension sensor 18 is provided on the side of the slider 16. A placement frame 19 is fixed to the right side of the front of the vertical baffle 3. A display screen 20 is fixed inside the placement frame 19. The display screen 20 is electrically connected to the tension sensor 18. During the lifting process of the container bag, the tensile test results of the container bag can be displayed on the display screen 20 through the tension sensor 18, which is convenient for the tester to observe.

[0023] Both the left clamping plate 9 and the right clamping plate 10 have bag clamping blocks 21 fixed on their opposite sides. Both bag clamping blocks 21 are arc-shaped to prevent wear on the sides of the container bag when clamping it. The top and bottom of the placement frame 19 are fixed with fixed plates 22. Both fixed plates 22 are fixedly connected to the front of the vertical baffle 3, which can better protect the display screen 20. The bottom side of the slider 16 and the top side of the hook 17 are fixed with reinforcing blocks 23. The reinforcing blocks 23 are square to reinforce the hook 17. The bottom of the multiple support legs 2 is fixed with support plates 24. The bottom surface of the multiple support plates 24 is rough to enhance the stability of the overall device.

[0024] Working principle: First, the container bag is placed on top of the base plate 1, and the items are placed inside the container bag. Then, according to the size of the container bag, the drive motor 7 is started to rotate, which causes the drive screw 8 to rotate. Since the threads on both sides of the drive screw 8 are opposite, the left clamping plate 9 and the right clamping plate 10 can move towards each other. When the left clamping plate 9 and the right clamping plate 10 have both moved to the side of the container bag, the container bag can be prevented from shifting position during the tensile performance test. Then, the pull ropes around the top of the container bag are tied together to form a closed structure. At this time, the lifting motor 14 controls the lifting screw 15 to rotate, causing the slider 16 to move down with the hook 17. Thus, the hook 17 can lift the pull ropes tied together on the top of the container bag. During the lifting process of the container bag, the tensile test results of the container bag can be displayed on the display screen 20 through the tensile sensor 18 for easy observation by the tester.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
