[0002] A woven bag, also known as a snake skin bag, is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Woven bags are often used for packaging agricultural materials products. When testing woven bags, it is necessary to conduct a load-bearing test on them to verify whether the woven bags are qualified. The traditional testing method uses manual verification, which is inaccurate. Therefore, a woven bag load-bearing test device is needed.

[0003] After retrieval, a Chinese patent with the publication number CN113607566A discloses a load-bearing test device for woven bags. This structure can clamp and fix the woven bag by setting a lower ring plate and an upper ring plate. By putting heavy objects inside it and cooperating with the data measured by the pressure sensor, its load-bearing strength can be detected. It can also pull the woven bag up at the same time to test the anti-destruction strength of the woven bag due to inertia when it suddenly rises during the handling process, and can obtain more accurate test data.

[0004] However, the following problems will occur during the use of the above device: After testing a woven bag, it is necessary to manually take out the heavy objects from the woven bag and prepare for the next round of testing. In the test of the load-bearing degree of the woven bag, the operation is cumbersome, time-consuming, and the labor intensity of workers is high, which is not conducive to quickly testing the strength of the woven bag.

[0019] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a woven bag load-bearing test device includes a working plate 1. Support columns 2 are provided at the four corners of the bottom of the working plate 1. A support frame 3 is provided on the top of the working plate 1. A connection mechanism is provided inside the support frame 3. A test mechanism is provided on one side of the support frame 3. The test mechanism includes a motor 4 provided on one side of the support frame 3. The output end of the motor 4 is provided with a lead screw 5. One end of the lead screw 5 extends into the support frame 3. A slider 6 is provided on the lead screw 5. A hydraulic cylinder 7 is provided at the bottom of the slider 6. One end of the hydraulic cylinder 7 is provided with a connecting plate 8. A test block 9 is provided at the bottom of the connecting plate 8. Two bolts 10 are provided on the surface of the connecting plate 8. One end of each of the two bolts 10 extends into the test block 9.

[0020] In this embodiment: The motor 4 drives the lead screw 5 to rotate. The lead screw 5 drives the test block 9 at the bottom to move left and right through the slider 6, facilitating the adjustment of the position of the test block 9 according to the size of the woven bag, so that the woven bag can be better tested. Then, the hydraulic cylinder 7 at the bottom of the slider 6 drives the connecting plate 8 to move downward, and the connecting plate 8 drives the test block 9 to move up and down. When the test block 9 moves downward, it enters the woven bag for load-bearing testing and squeezes the woven bag. The extension length of the hydraulic cylinder 7 is gradually increased to increase the pressure on the woven bag to simulate the load-bearing of the woven bag, improving the testing efficiency of the woven bag. There is no need to spend a lot of time and manpower to take the heavy object out of the woven bag for testing. Moreover, the connecting plate 8 and the test block 9 are connected by bolts 10, enabling the replacement of the test block 9 at the bottom of the connecting plate 8 to test woven bags with different load-bearing capacities, improving the testing efficiency of the device.

[0021] Please refer particularly to Figure 3 and Figure 4 As shown, the connecting mechanism includes a plurality of first electric telescopic rods 11 arranged inside the support frame 3. One ends of the plurality of first electric telescopic rods 11 are all provided with fixing plates 12. Through holes are formed through the surfaces of the fixing plates 12. Connecting grooves are formed around the fixing plates 12. Second electric telescopic rods 13 are arranged inside the plurality of connecting grooves.

One ends of the second electric telescopic rods 13 extend into the connecting frames 14. Sleeves 15 are arranged at one ends of the second electric telescopic rods 13. The sleeves 15 are slidably connected to the connecting frames 14.

[0022] In this embodiment: The size of the opening can be adjusted according to the size of the woven bag. The second electric telescopic rod 13 drives the sleeve 15 to move, so that the sleeve 15 can expand the four sides of the woven bag, thereby facilitating the adjustment of the size of the opening of the woven bag, so that the test block 9 can enter the woven bag for testing, improving the testing effect of the woven bag. When the first electric telescopic rod 11 drives the fixing plate 12 to move up and down, the woven bag can be lifted, so that the load-bearing condition of the woven bag when it is under the pressure of a heavy object during the lifting process can be simulated, and the practicability is relatively strong.

[0023] Please refer particularly to Figure 3 and Figure 5 As shown, a plurality of clamping blocks 16 are rotatably connected to the surface of the fixing plate 12. A plurality of clamping grooves are arranged on the surface of the connecting frame 14. The clamping blocks 16 are connected to the clamping grooves.

[0024] In this embodiment: The opening of the woven bag is sleeved on the surface of the fixing plate 12, and then the clamping block 16 is rotated to clamp the clamping block 16 on the surface of the woven bag. The clamping block 16 is connected to the clamping groove on the surface of the connecting frame 14 to fix the woven bag.

[0025] Working principle of the utility model: First, the opening of the woven bag is sleeved on the surface of the fixed plate 12, and then the clamping block 16 is rotated to clamp the clamping block 16 on the surface of the woven bag. The clamping block 16 is connected to the card slot on the surface of the connecting frame 14 to fix the woven bag. The clamping block 16 is composed of a telescopic plate, and the telescopic plate is composed of an outer plate and an inner plate. The inner plate slides inside the outer plate, and the outer plate is hollow. An electric push rod is installed inside the outer plate. The electric push rod drives the inner plate to slide inside the outer plate, and the size of the opening can be adjusted according to the size of the woven bag. The electric telescopic rod II 13 drives the sleeve 15 to move, so that the sleeve 15 can expand the four sides of the woven bag, so as to facilitate the adjustment of the size of the opening of the woven bag, so that the test block 9 can enter the woven bag for testing, improving the test effect of the woven bag. When the electric telescopic rod I 11 drives the fixed plate 12 to rise and fall, the woven bag can be lifted, so that the load-bearing situation of the woven bag under the pressure of heavy objects during the lifting process can be simulated, and the practicability is strong. First, the motor 4 drives the lead screw 5 to rotate, and the lead screw 5 drives the test block 9 at the bottom through the slider 6 to move left and right, facilitating the adjustment of the position of the test block 9 according to the size of the woven bag, so that the woven bag can be better tested;

[0026] Then, the hydraulic cylinder 7 at the bottom of the slider 6 drives the connecting plate 8 to move downward, and the connecting plate 8 drives the test block 9 to move up and down. When the test block 9 moves downward, it enters the woven bag for load-bearing test and squeezes the woven bag. The extension length of the hydraulic cylinder 7 is gradually increased to increase the pressure on the woven bag to simulate the load-bearing of the woven bag, improving the test efficiency of the woven bag. There is no need to spend a lot of time and manpower to take the heavy object out of the woven bag for testing. Moreover, the connecting plate 8 and the test block 9 are connected by bolts 10, so that the test block 9 at the bottom of the connecting plate 8 can be replaced to test woven bags with different load-bearing capacities, improving the test efficiency of the device.
