DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, a packaging bag load-bearing capacity testing device comprises a base 1, a fixed portion 2 is arranged on the base 1, a guide rod 3 is arranged on the base 1, a moving portion 4 is slidably connected to the guide rod 3, handles on both sides of the packaging bag 25 are hung on the fixed portion 2 and the moving portion 4 respectively, vertical rods 5 are symmetrically arranged on the base 1 and on the same side of the fixed portion 2 and the moving portion 4, two fixed plates 6 are arranged on the two vertical rods 5, a lead screw 7 is arranged between the two fixed plates 6, and a motor 8 for driving the lead screw 7 to rotate is arranged on one side of one of the fixed plates 6 A movable plate 9 is threadedly connected to the lead screw 7, and both ends of the movable plate 9 are slidably connected to the vertical poles 5 on both sides respectively. A support rod 10 is arranged on one side of the movable plate 9, and a flexible water storage bag 11 is arranged below the support rod 10. The water storage bag 11 is connected to the support rod 10 by a rope body 12. A water filling port 13 is arranged at the upper end of the water storage bag 11, a water storage tank 14 is arranged on the base 1, and a water pump 15 is arranged at the upper end of the water storage tank 14. A water pipe 16 is arranged at the water outlet end of the water pump 15, and the water outlet end of the water pipe 16 is arranged at the inner bottom of the water storage bag 11.

[0018] The material of the vertical rod 5 is aluminum profile, and a slide groove is provided on the outer surface of the vertical rod 5. Both ends of the movable plate 9 are provided with guide rails that match the slide groove on the outer surface of the vertical rod 5, so that the movable plate 9 can slide along the vertical rod 5 and prevent the movable plate 9 from rotating. The lead screw 7 is driven to rotate by the motor 8. The threaded connection between the lead screw 7 and the movable plate 9 can control the movable plate 9 to move upward or downward between the two vertical rods 5. When the movable plate 9 moves upward, the movable plate 9 drives the support rod 10 to move upward, and the support rod 10 drives the water storage bag 11 to move upward through the rope body 12, so that the water storage bag 11 is taken out of the packaging bag 25; when the lead screw 7 is driven by the motor 8 to rotate in the opposite direction, the water storage bag 11 can be driven to move downward, and the packaging bag 25 is suspended on the fixed part 2 and the movable part 4, and the water storage bag 11 moves downward into the packaging bag 25, so as to test the load-bearing capacity of the packaging bag 25.

[0019] The rope body 12 can be a cotton rope, a hemp rope, a plastic rope, a rubber rope, a steel wire rope, a chain, etc. When the rope body 12 is in a non-tensioned state and the bottom of the water storage bag 11 contacts the bottom of the packaging bag 25, and the water storage bag 11 is in a large folded and compressed state, the motor 8 stops working and the preparation for placing the water storage bag 11 is completed.

[0020] The water storage bag 11 includes a top cover 23 and a water storage chamber 24. The material of the water storage chamber 24 is plastic and / or rubber, and the material of the top cover 23 is a hard plastic plate. The top cover 23 in the water storage bag 11 is connected to the support rod 10 through a rope body 12, and the water inlet 13 is set on the top cover 23. The gravity of the top cover 23 and the water storage chamber 24 of the water storage bag 11 all acts on the packaging bag 25. The overall weight of the water storage bag 11 is constant. In subsequent tests, the load-bearing capacity of the packaging bag 25 is the weight of the water in the water storage bag 11 and the weight of the water storage bag 11 itself. The weight of the water pipe 16 is within the error range of the test and is negligible here.

[0021] Furthermore, the fixed part 2 and the movable part 4 both include a support block 17, the upper end surface of the support block 17 is arc-shaped, and the lower surface of the support block 17 is symmetrically provided with support rods 18, the support rods 18 in the fixed part 2 are fixed on the base 1, and the lower end of the support rods 18 in the movable part 4 is provided with a bottom plate 19, and the bottom plate 19 is provided with a through hole that cooperates with the guide rod 3. The handle of the packaging bag 25 is placed on the support block 17, and the arc-shaped surface can reduce the stress of the support block 17 on the handle of the packaging bag 25. Baffles 20 are provided on the sides of the support blocks 17 in the fixed part 2 and the movable part 4 and are close to each other. The baffle 20 can prevent the handle of the packaging bag 25 from sliding off the support block 17, thereby ensuring stable support for the packaging bag 25.

[0022] Furthermore, a horizontal plate 21 is provided on one side of the two support rods 18 in the movable part 4, and a handle 22 is provided on one side of the horizontal plate 21. The movable part 4 can slide on the guide rod 3 through the bottom plate 19, so as to increase the distance between the two support blocks 17, which is convenient for placing the packaging bag 25 between the two support blocks 17, and also convenient for placing the water storage bag 11 into the packaging bag 25. The movement of the movable part 4 can be conveniently controlled through the handle 22 and the horizontal plate 21.

[0023] Working principle: When in use, the movable part 4 is moved in the direction away from the fixed part 2, and then the two handles of the packaging bag 25 are respectively hung on the two support blocks 17, and then the motor 8 drives the screw 7 to rotate. The screw 7 cooperates with the movable plate 9 to drive the support rod 10 and the water storage bag 11 to move downward. When the water storage bag 11 completely enters the packaging bag 25, the movable part 4 is moved in the direction close to the fixed plate 6, and then the water in the water tank 14 is input into the water storage bag 11 through the water pipe 16 by the water pump 15. After the water storage bag 11 is filled with water, the pressure of the water storage bag 11 and the water is all pressed on the bottom of the packaging bag 25. A certain amount of water is continuously injected into the water storage bag 11 in a step-by-step manner until the handle of the packaging bag 25 is separated from the packaging bag 25 or the bottom of the packaging bag 25 is cracked. The weight of the water is calculated by the volume of the injected water, and then the weight of the water storage bag 11 is added to test the load-bearing capacity of the packaging bag 25.

[0024] After completing the load-bearing capacity test of the packaging bag 25 , the water in the water storage bag 11 is pumped back into the water storage tank 14 through the water pump 15 and the water pipe 16 to facilitate subsequent load-bearing capacity tests of the remaining packaging bags 25 .

[0025] The packaging bag 25 tested can be made of paper or plastic.

[0026] The device can quickly inject water into the water storage bag 11 and pump water out of the water storage bag 11 through the water pump 15, thereby realizing the rapid transfer of water, that is, the counterweight, improving the testing convenience of the packaging bag 25 and improving the testing efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
