[0002] With the growth of global trade and the rapid development of the logistics industry, there is an increasing demand for packaging materials that can protect goods from physical damage, environmental impact, and facilitate handling and storage. Woven bags are widely used in many industries such as agriculture, chemicals, and food because of their lightness, strength, and ease of customization.

[0003] In the production of woven bags, woven bags made of common plastic materials such as polypropylene and polyethylene usually need to be sampled from the finished product or the entire woven bag for testing during quality inspection. Most current testing equipment uses a step-by-step approach to evaluate the physical properties of woven bags item by item, resulting in a long complete quality inspection cycle. This method is not only time-consuming but also reduces production efficiency for companies pursuing efficient and centralized testing. Therefore, there is an urgent need for a testing solution that can comprehensively evaluate all key performance indicators of woven bags at one time to improve testing speed and production efficiency.

[0007] As a further improvement of the present invention, the fixing mechanism includes a plug-in block arranged on one side of the rotating plate, and two plug-in holes are provided on the movable frame. The plug-in end of the plug-in block passes through the rotating plate and is plugged into one of the plug-in holes. A ring is fixedly sleeved on one end of the plug-in block away from the plug-in hole, and a second spring is fixedly connected to the ring and sleeved with the plug-in block, and the other end of the second spring is fixedly connected to the rotating plate.

[0008] As a further improvement of the present invention, the driving mechanism includes a dual-axis motor fixedly connected to the lower end of the workbench, and the two output shaft ends of the dual-axis motor are fixedly connected to threaded rods. The lower ends of the two moving blocks are provided with threaded grooves, and the other ends of the two threaded rods are respectively threaded through the two threaded grooves and extend outward.

[0009] As a further improvement of the present invention, the telescopic mechanism includes a mounting frame fixedly connected to the lower end of the workbench, and two cylinders are fixedly connected in the mounting frame. The two cylinders are respectively located on both sides of the dual-axis motor, and through grooves are opened on both sides of the bottom of the groove.

[0014] Beneficial effects of the present invention: By setting up a clamping mechanism and a driving mechanism, and driving the threaded rod to rotate through a dual-axis motor, which in turn drives the moving block to move linearly along the sliding groove, the gradual stretching of the two ends of the woven bag is achieved, ensuring that the force during the stretching process is uniform and controllable.

Combined with the stretching function of the dual-axis motor, tension can be applied to the woven bag in the wound state. This composite stress test is closer to actual usage scenarios, such as the torsional deformation that may occur during transportation, which is crucial for testing the durability and reliability of woven bags under non-ideal conditions.

[0016] By setting up a detection mechanism, the hydraulic cylinder and the pressure probe can work together to apply gradually increasing pressure to the seams of the woven bag until it breaks, and the pressure value and the failure mode can be recorded in real time on the display. This method can accurately evaluate the quality and firmness of the suture line, and by accurately measuring the maximum load-bearing capacity of the sutured part, it can ensure that each woven bag meets safety standards and avoid damage or leakage of goods caused by suture failure during transportation.

[0017] Through the integrated design of the present invention, the detection equipment can simultaneously complete multiple physical property tests in a single operation, significantly improving work efficiency and ensuring the accuracy and consistency of data. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Figure 1-Figure 7A testing device for the production of plastic woven bags includes a workbench 1. The workbench 1 serves as the basic platform of the entire device and carries all mechanical components. Two sliding grooves 2 are provided at the upper end of the workbench 1. Moving blocks 12 are slidably arranged in the two sliding grooves 2. The two sliding grooves 2 are both rectangular structures. The design of the sliding grooves 2 allows the moving blocks 12 to perform linear motion therein. A moving frame 7 is fixedly connected to the upper end of the moving block 12. A rotating shaft 21 is penetrated through the two moving frames 7. The ends of the two rotating shafts 21 close to each other are fixed. A turntable 8 is connected, and a clamping mechanism is provided on both turntables 8. The arrangement of the rotating shaft 21 and the turntable 8 enables the clamping mechanism to rotate around the rotating shaft 21, providing an additional degree of freedom, and can perform multi-angle stretching or torsion tests on the woven bag, increasing the diversity and flexibility of the test. The clamping mechanism includes a lower clamping plate 13 fixedly connected to the side wall of the turntable 8, an upper clamping plate 14 is movably provided above the lower clamping plate 13, an upper electromagnet 15 is fixedly connected to the lower end of the upper clamping plate 14, and a lower electromagnet 16 is fixedly connected to the upper end of the lower clamping plate 13. The clamping mechanism uses the attraction between the upper electromagnet 15 and the lower electromagnet 16 after power is applied to tighten the woven bag sample, which not only ensures firmness, but also can adjust the clamping force by controlling the current size, which is suitable for woven bags of different thicknesses and strengths. The upper end of the lower clamping plate 13 is fixedly connected to two guide rods 17, and the two guide rods 17 are used to enable the upper clamping plate 14 to move smoothly in the vertical direction. The upper ends of the two guide rods 17 both penetrate the upper clamping plate 14 and are fixedly connected to a fixing plate 31. The two fixing plates 31 are used to limit the moving range of the guide rods 17. The lower ends of the two fixing plates 31 are fixedly connected to a first spring 18 sleeved with the two guide rods 17. The other ends of the two first springs 18 are fixedly connected to the upper end of the upper clamping plate 14. The two first springs 18 are used to enable stable clamping between the upper clamping plate 14 and the lower clamping plate 13 without being affected by external forces. The upper end of the upper clamping plate 14 is located between the two guide rods 17 and is fixedly connected to a pulling block 19, which is used to assist in pulling the upper clamping plate 14.

[0022] The ends of the two rotating shafts 21 that are away from each other are fixedly connected to the rotating plates 20. The two rotating plates 20 are provided with fixing mechanisms that limit their rotation. The fixing mechanisms are used to lock the position of the rotating plates 20 to ensure that the turntable 8 will not rotate accidentally during the test process and maintain the stability and accuracy of the test conditions. The fixing mechanism includes a plug-in block 22 arranged on one side of the rotating plate 20. Two plug-in holes 25 are provided on the movable frame 7. The plug-in end of the plug-in block 22 passes through the rotating plate 20 and is plugged into one of the plug-in holes 25. A collar 23 is fixedly sleeved on the end of the plug-in block 22 away from the plug-in hole 25. A second spring 24 that is sleeved with the plug-in block 22 is fixedly connected to the collar 23. The other end of the second spring 24 is fixedly connected to the rotating plate 20. The fixing mechanism uses the force of the second spring 24 to tightly insert the plug-in block 22 into the plug-in hole 25 to prevent the rotating plate 20 from rotating uncontrolled. At the same time, when unlocking is required, the plug-in block 22 can be easily pulled out by simply overcoming the spring force of the second spring 24.

[0023] A driving mechanism for driving the two moving blocks 12 to move is provided at the lower end of the workbench 1, and the driving mechanism includes a dual-axis motor 27 fixedly connected to the lower end of the workbench 1, and the two output shaft ends of the dual-axis motor 27 are fixedly connected to threaded rods 29, and the lower ends of the two moving blocks 12 are provided with threaded grooves 30, and the other ends of the two threaded rods 29 are respectively threaded through the two threaded grooves 30 and extend outward, and support frames 3 are fixedly connected on both sides of the lower end of the workbench 1, and the ends of the two threaded rods 29 away from the dual-axis motor 27 are respectively rotatably connected to the inner side walls of the two support frames 3, and the driving mechanism drives the threaded rods 29 to rotate through the dual-axis motor 27, thereby driving the moving block 12 to move along the sliding groove 2, thereby realizing the tensile test of the woven bag, and at the same time, the support frame 3 provides a stable fulcrum for the threaded rods 29 to ensure the accuracy of the movement.

[0024] A groove 32 is provided at the upper end of the workbench 1, and a pressure block 11 is provided in the groove 32 for sliding up and down. A telescopic mechanism for driving the pressure block 11 to move is provided at the lower end of the workbench 1, and the telescopic mechanism includes a mounting frame 10 fixedly connected to the lower end of the workbench 1, and two cylinders 26 are fixedly connected in the mounting frame 10. The two cylinders 26 are respectively located on both sides of the dual-axis motor 27, and through grooves 28 are provided on both sides of the bottom of the groove 32. The telescopic ends of the two cylinders 26 respectively pass through the two through grooves 28 and are fixedly connected to the lower end of the pressure block 11. The telescopic mechanism composed of the pressure block 11 and the cylinder 26 can apply vertical pressure during the test to simulate the load conditions in actual use, and further verify the durability and reliability of the woven bag.

[0025] A detection mechanism for detecting the suture strength is provided at the upper end of the workbench 1, and the detection mechanism includes a mounting frame 4 fixedly connected to the upper end of the workbench 1, the mounting frame 4 is an inverted L-shaped structure, the mounting frame 4 is located between two moving frames 7, and a hydraulic cylinder 5 is fixedly connected to the upper end of the mounting frame 4, the telescopic end of the hydraulic cylinder 5 passes through the mounting frame 4 and is fixedly connected to a pressure probe 33, a display 6 is fixedly connected to one side of the upper end of the mounting frame 4, and a controller 9 is fixedly connected to one side of the workbench 1. The detection mechanism is used to evaluate the strength of the suture of the woven bag, the hydraulic cylinder 5 can provide adjustable pressure, and the pressure probe 33 is responsible for measuring the actual force and transmitting the data to the display 6 for display, so as to facilitate the operator to read and record the test results.

[0026] When the present invention is used, the following schemes can be used to detect the woven bag: The first one: The worker places the two ends of the woven bag to be tested in the two clamping mechanisms respectively, and drives the upper clamping plate 14 to separate from the lower clamping plate 13 by pulling the pulling block 19, and then places one end of the woven bag inside. After placing it, release the pulling block 19, and the upper clamping plate 14 will move downward under the action of the two first springs 18 to clamp one end of the woven bag. At the same time, the upper electromagnet 15 and the lower electromagnet 16 are connected to an external power supply. The upper electromagnet 15 will be tightly connected with the lower electromagnet 16, and then the woven bag will be firmly fixed. When both ends of the woven bag are fixed in the above manner, start the dual-axis motor 27 to drive the two threaded rods 29 to rotate. The rotation of the two threaded rods 29 will drive the two moving blocks 12 to move away from each other and then drive the two moving frames 7 to move away from each other, so as to detect the tensile resistance of the woven bag. At the same time, start the two cylinders 26 to drive the pressure block 11 to lift. The lifting of the pressure block 11 will press the woven bag, and then the tensile resistance of the woven bag can be further tested.

[0027] This scheme mainly tests the longitudinal tensile strength of the woven bag, and simulates the pulling situation in actual use by applying mechanical force. Combined with the effect of the pressing block 11, it can also test the ability of the woven bag to resist local concentrated force.

[0028] Second type: The worker will first fix the woven bag through two clamping mechanisms in the above manner, and then drive the rotating plate 20 to rotate through one of the fixing mechanisms, and then drive one end of the woven bag to rotate, and drive its plug-in end to disengage from the plug-in hole 25 by pulling the plug-in block 22, and then rotate the rotating plate 20 with the rotating shaft 21 as the axis. The rotation of the rotating plate 20 will drive the turntable 8 to rotate through the rotating shaft 21, and then one end of the fixed woven bag can be rotated, so that the woven bag is in a entangled state, and then the dual-axis motor 27 is driven to drive the two threaded rods 29 to rotate, and then drive the two movable frames 7 to move away from each other, and the tensile resistance of the woven bag after winding can be tested. The woven bag can be wound multiple times, and the tensile resistance can be tested for different numbers of turns.

[0029] This method tests the tensile properties of the woven bag under torsional deformation and its ability to withstand tension in a entangled state, which is very important for understanding the performance of the woven bag under complex stress conditions.

[0030] The third type: The worker will first fix the woven bag by two clamping mechanisms in the above manner, and then drive the dual-axis motor 27 to drive the two movable frames 7 to move away from each other. After pulling the woven bag straight, the worker will drive the hydraulic cylinder 5 to drive the pressure probe 33 to move downward. The pressure probe 33 is fixedly connected with a breaking cone. When the breaking cone breaks the woven bag, the data such as the force generated by the downward pressure will be transmitted to the display 6 through wireless data through the pressure probe 33, and then the data will be analyzed internally by the display 6 and displayed.

[0031] The last solution focuses on testing the strength of the seams of woven bags. By gradually increasing the pressure until the material breaks, the maximum load-bearing capacity of the seams can be accurately found, which is crucial to ensuring product quality.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
