Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and more specifically, to a tensile performance detection device for ton bags. Background Art

[0002] Ton bags are widely used in chemical industry, building materials, food, agriculture and other fields. Ton bags can be used for the treatment and transportation of hazardous wastes, the packaging and transportation of agricultural products such as fertilizers and pesticides, and the packaging and transportation of energy materials such as coal and oil. During the production process of ton bags, the tensile properties of ton bags need to be tested, and the tensile properties testing of ton bags requires the use of tensile properties testing devices.

[0003] Chinese patent application number CN202323321846.9 discloses a tensile test device for ton bags, including a platform, a first transmission assembly and a second transmission assembly are respectively installed on both sides of the top of the platform, a first connecting rod is connected to the top of the first transmission assembly, a first sleeve shaft is installed on the first connecting rod, a second connecting rod is connected to the top of the second transmission assembly, and a second sleeve shaft is installed on the second connecting rod. The annular ton bag strip is looped on the first sleeve shaft of the first connecting rod and the second sleeve shaft of the second connecting rod, and then the first transmission assembly drives the first sleeve shaft of the first connecting rod to move backward, and the second transmission assembly drives the second sleeve shaft of the second connecting rod to move in the opposite direction of the movement direction of the first transmission assembly, so as to perform a tensile test on the annular ton bag strip.

[0004] In the above technical solution, the annular ton bag strips are stretched by the first transmission assembly and the second transmission assembly, so that the tensile resistance of the ton bag can be simulated and tested, and the operation is convenient and the test is efficient. The traditional ton bag tensile performance detection device detects the annular ton bag strips, and infers the overall tensile performance of the ton bag by detecting a small part of the strips. Although this method improves the efficiency and accuracy of the detection to a certain extent, it still has certain limitations and preliminary evaluation problems. Due to the complex structure of the ton bag, the tensile performance of different parts may be different. Only by detecting a small part of the strips, it is impossible to fully reflect the overall tensile performance of the ton bag. Secondly, this detection method requires the ton bag to be cut into strips, which destroys the overall structure of the ton bag and is not conducive to subsequent use. Summary of the invention

[0046] The use steps of the present invention are as follows: when the tensile performance testing device for ton bags is used, the ton bags that have been initially produced are tested (when testing the ton bags that have been initially produced, the two ports of the ton bags are open, and after the tensile performance test of the ton bags is qualified, the bottom of the ton bags is further sewn). Before the test, the two fixing rings 4 are adjusted according to the length of the ton bags, so that the two fixing rings 4 are adapted to the ton bags that need to be tested, the motor 35 rotates with the bidirectional screw rod 19 to rotate, so that the two sliders 3 move toward each other with the fixing rings 4, and then the two end ports of the ton bag are clamped respectively. During the clamping process, the port of the ton bag is first passed through between the first clamping plate 5 and the second clamping plate 8, and then the telescopic device 24 extends with the pentagonal prism 10 to move toward the frame ring 6 When the pentagonal prism 10 moves with the slope groove 11 to squeeze the ball head 39, the guide rod 7 moves with the second clamping plate 8 to the direction of the first clamping plate 5. As the telescopic device 24 continues to extend, the first clamping plate 5 and the second clamping plate 8 are in contact with each other, and the teeth on the surfaces of the first clamping plate 5 and the second clamping plate 8 are engaged to clamp and fix the port of the ton bag. The electric telescopic rod 29 retracts and moves the lifting block 28, the lifting plate 12 and the tension detector 13 upward. When the tension hook 18 contacts the surface of the ton bag, the position of the pointer 16 is marked and recorded. When the tensile performance of the ton bag is tested, the lifting block 28, the lifting plate 12 and the tension detector 13 continue to move upward, and the tension hook 18 applies a stable tension to pull up the middle position of the ton bag. At this time, the tension hook 18 is subjected to the tension of the ton bag, so that the slide plate 15 moves downward with the pointer 16, and the position detector 31 detects the position of the pointer 16 and the scale 34 in real time, and presents the data of the tensile resistance of the ton bag detected by the position detector 31 on the surface of the display 38 in real time to judge whether the tensile resistance of the ton bag is qualified. This scheme first passes the port of the ton bag between the first clamping plate 5 and the second clamping plate 8, and then the telescopic device 24 extends and moves the pentagonal prism 10 toward the frame ring 6. The movement of the pentagonal prism 10 brings the slope groove 11 to squeeze the ball head 39, and the second clamping plate 8 follows the guide rod 7 to move and contact the first clamping plate 5. The teeth on the surface of the first clamping plate 5 and the second clamping plate 8 mesh with each other to clamp and fix the port of the ton bag. When the tension hook 1 When the pull detector 13 contacts the surface of the ton bag, the position of the pointer 16 is marked and recorded. As the tension detector 13 continues to move upward, the tension hook 18 applies a stable tension to pull up the middle position of the ton bag. At this time, the tension hook 18 is subjected to the tension of the ton bag, so that the slide plate 15 moves downward with the pointer 16. The position detector 31 detects the position of the pointer 16 and the scale 34 in real time, and uses the data of the tensile resistance of the ton bag detected by the position detector 31 to judge the tensile resistance of the ton bag. Compared with the traditional detection device, the detection device body 1 directly performs a comprehensive tensile resistance test on the entire ton bag, and does not need to cut the ton bag into strips, which reduces the steps of the tensile resistance test of the ton bag, thereby improving the efficiency and accuracy of the tensile resistance test of the ton bag.Before testing, adjust the two fixing rings 4 according to the length of the ton bag so that the two fixing rings 4 are adapted to the ton bag to be tested. The motor 35 rotates to drive the bidirectional screw rod 19 to rotate, so that the two sliders 3 move toward each other and drive the fixing rings 4 to move. Then, clamp the two ends of the ton bag respectively, and test the tensile performance of ton bags of different sizes, thereby increasing the functionality and practicality of the testing device body 1. ;

[0047] Example 2: Please refer to Figure 1 - Fig.10 The difference between the two embodiments is that two pairs of connecting plates 40 are fixedly installed on the surface of the fixing ring 4, and a rotating shaft 43 is arranged between any pair of connecting plates 40. A rotating rod 44 is arranged on the surface of the rotating shaft 43, and a clamp 41 is fixedly installed on one end surface of the rotating rod 44. The clamp 41 is rotatably connected to the connecting plate 40 by matching the rotating rod 44 and the rotating shaft 43. A semi-cylinder 42 clamped with the clamp 41 is fixedly installed on the surface of the fixing ring 4. After the teeth on the surfaces of the first clamping plate 5 and the second clamping plate 8 are meshed to clamp and fix the port of the ton bag, the port of the ton bag is turned outward along the fixing ring 4, so that the port of the ton bag contacts the surface of the semi-cylinder 42, and then the clamp 41 is rotated so that the clamp 41 and the semi-cylinder 42 are matched and clamped. At this time, the clamp 41 and the semi-cylinder 42 further clamp and fix the port of the ton bag, and prevent the port of the ton bag from dislocating during the tensile performance test of the ton bag, thereby ensuring the stability of the tensile performance test process of the ton bag.

[0048] The use steps of the present invention are as follows: when the tensile performance testing device for ton bags is in use, in the process of tensile performance testing of the ton bags, in order to prevent the ton bags from dislocating, the first clamping plate 5 and the second clamping plate 8 are in contact with each other, and the teeth on the surfaces of the first clamping plate 5 and the second clamping plate 8 are meshed to clamp and fix the port of the ton bag, and then the port of the ton bag is turned outward along the fixing ring 4, so that the port of the ton bag contacts the surface of the semi-cylinder 42, and then the clamp 41 is rotated so that the clamp 41 and the semi-cylinder 42 are matched and clamped, and at this time, the clamp 41 and the semi-cylinder 42 are clamped to the end of the ton bag. The opening of the ton bag is further clamped and fixed. After the teeth on the surfaces of the first clamp plate 5 and the second clamp plate 8 mesh with each other to clamp and fix the port of the ton bag, the port of the ton bag is turned outward along the fixing ring 4 so that the port of the ton bag contacts the surface of the semi-cylinder 42. Then the clamp 41 is rotated to match and clamp the semi-cylinder 42. At this time, the clamp 41 and the semi-cylinder 42 further clamp and fix the port of the ton bag. During the tensile performance test of the ton bag, the port of the ton bag is prevented from being dislocated, thereby ensuring the stability of the tensile performance test process of the ton bag.
