Description

Technical Field

[0001] The invention relates to the technical field of container bag testing equipment, and in particular to a testing equipment for producing high tear-resistant container bags. Background Art

[0002] In the field of modern industrial logistics, ton bags, as a common type of highly tear-resistant container bags, are widely used in the packaging and transportation of various bulk materials. Due to their large carrying capacity and convenient use, ton bags have become an indispensable packaging tool in many industries. However, in the actual production process of ton bags, they usually need to undergo rigorous pressure tests and drop tests to ensure their performance stability and reliability.

[0003] The pressure test is designed to simulate the pressure that the bulk bag may face during transportation or stacking in order to evaluate its pressure resistance. This test is of great significance for preventing the bulk bag from being damaged due to external pressure. The drop test is to evaluate the ability of the bulk bag to protect the internal materials in the event of an accidental fall, thereby ensuring its safety in a complex logistics environment. When the existing testing equipment is testing the ton bag, the materials need to be manually added to the ton bag. This operation is not only cumbersome, time-consuming and labor-intensive, but also, when the ton bag is damaged during the test, the internal materials will be scattered all over the floor. The cleaning work is time-consuming and labor-intensive, and it will also cause material waste and increase the company's operating costs. In addition, the current pressure test and drop test usually need to be completed using two independent devices, which not only takes up a large production space, but also increases the cost of equipment procurement and maintenance. Summary of the invention

The pressure sensor monitors the applied pressure value in real time and uploads the data to an external display. This design not only realizes the automation of the pressure test, but also integrates the drop test function, which can greatly reduce the equipment footprint, reduce procurement and maintenance costs, and improve the economic benefits of the enterprise.

[0015] 3. When adding materials to ton bags, the present invention can press the top of the block through the roller to prevent the first electric push rod from being damaged by the force. At the same time, when the ton bag is pressurized, the clamping rod can be controlled to move into the clamping groove of the connecting rod, so that the support frame can support the connecting rod to prevent the first winch from being damaged by the force. In this way, the stable operation of the equipment can be ensured and the service life of the equipment can be extended. Moreover, by controlling the connecting plate to rotate in an inclined state through the second winch, it can be ensured that all the materials in the collection frame can fall into the first spiral feeder for loading.

[0030] like Figure 3-Figure 5As shown, the lifting mechanism includes a first winch 9, a connecting rod 10, a fixed block 11, a rotating hook 12, a first torsion spring 13, an anti-slip assembly and a locking assembly. The first winches 9 are installed on both the front and rear sides of the top of the support frame 2. Two first winches 9 are provided with two winding wheels and two steel ropes. The number of steel ropes is four and they are distributed in a rectangular shape. The four steel ropes all slide through the top of the support frame 2, and the lower ends of the four steel ropes are connected to the connecting rod 10. The diameter of the lower part of the connecting rod 10 is greater than the diameter of the upper part, and the upper part of the connecting rod 10 slides through the top of the lifting frame 7, and the lower part of the connecting rod 10 contacts the top inside the lifting frame 7, so that when the connecting rod 10 moves upward, it can push the lifting frame 7 to move upward synchronously, and when the connecting rod 10 moves downward, the lifting frame 7 will Due to the gravity, the four connecting rods 10 move downward synchronously with the connecting rod 10.

The lower part of the four fixed blocks 11 is symmetrically connected to two fixed rods 14, and a rotating block 15 is rotatably connected between the lower parts of the two fixed rods 14. The rotating block 15 corresponds to the rotating hook 12 one by one. Figure 4 As shown, the end of the rotating block 15 is placed on the end of the rotating hook 12, and the rotating hook 12 can limit the rotating block 15 so that the rotating block 15 can only rotate upward but cannot rotate downward. A second torsion spring 16 is wound around the rotating axis of each rotating block 15, and the two ends of the second torsion spring 16 are respectively connected to the rotating block 15 and the fixed rod 14; the locking assembly includes a first electric push rod 17 and a block 18, and each fixed block 11 is installed with a first electric push rod 17, and the telescopic rod of the first electric push rod 17 is connected with a block 18, the block 18 corresponds to the rotating hook 12 one by one, and the bottom of the block 18 contacts the top of the corresponding rotating hook 12, so that the rotating hook 12 can be locked to prevent the rotating hook 12 from rotating downward.

[0031] like Figure 6-Figure 9As shown, the pressure mechanism includes a connecting tube 19, a hydraulic cylinder 20, a pressure ring 21, a rotating cover 22, a third torsion spring 23, a mounting frame 24, a mounting plate 25 and a pressure sensor 26. Three connecting tubes 19 are connected to the top of the support frame 2 at intervals. Hydraulic cylinders 20 are slidably installed in the three connecting tubes 19. The bottoms of the telescopic rods of the three hydraulic cylinders 20 are connected with a pressure ring 21, and the lower end of the fixed pipe 6 passes through the inner side of the pressure ring 21, so as not to affect the feeding work of the fixed pipe 6, and the left side of the bottom of the pressure ring 21 is rotated. A rotating cover 22 is dynamically connected, and the rotating cover 22 is in contact with the fixed tube 6. A third torsion spring 23 is wound around the rotating axis of the rotating cover 22, and the two ends of the third torsion spring 23 are respectively connected to the rotating cover 22 and the pressure ring 21. A mounting frame 24 is connected between the outer walls of the three connecting tubes 19, and a mounting plate 25 is connected between the cylinder bodies of the three hydraulic cylinders 20. The mounting plate 25 is slidably connected to the mounting frame 24. A pressure sensor 26 is installed on the top of the mounting plate 25, and the top of the pressure sensor 26 is in contact with the inner top of the mounting frame 24.

[0032] In the initial state, the fixed tube 6 blocks the right side of the rotating cover 22, the rotating cover 22 is in the open state, and the third torsion spring 23 is in the deformed state; when the ton bag needs to be dropped, the first winch 9 is used to drive the connecting rod 10 to descend, and the connecting rod 10 can drive the fixed block 11 and the rotating hook 12 to move downward, and the lower part of the connecting rod 10 will be separated from the top of the lifting frame 7, so that the lifting frame 7 can fall down along the support frame 2 due to gravity, so that the blocking cloth 8 can be folded and put away, and then an appropriate amount of materials are manually put into the collecting frame 3, and then the rotating block 15 is rotated upward to be aligned with the rotating hook 12. The second torsion spring 16 is deformed, and the four slings of the ton bag are hung on the four rotating hooks 12 respectively, and then the rotating block 15 is released, the second torsion spring 16 will return to its original state, driving the rotating block 15 to rotate downward and re-contact the rotating hook 12, the rotating block 15 can prevent the sling of the ton bag from being separated from the rotating hook 12, and then the first winch 9 drives the connecting rod 10 to rise, the lower part of the connecting rod 10 will push the lifting frame 7 to move upward along the support frame 2 to reset, so that the blocking cloth 8 can be unfolded to block the surroundings above the collection frame 3, and the connecting rod 10 can drive the fixed block 11 and the rotating hook 12 to move upward. The rotating hook 12 can drive the ton bag to move upward to the lower end of the fixed pipe 6, and then the first screw feeder 4 and the second screw feeder 5 cooperate to transport the materials in the collection frame 3 to the fixed pipe 6. Then the materials in the fixed pipe 6 will fall down along its inner wall to the inside of the ton bag, so that the materials can be automatically added to the ton bag. When the ton bag is filled with a proper amount of materials, the first screw feeder 4 and the second screw feeder 5 can be closed, and then the ton bag can be controlled to be lifted and lowered by the first winch 9 to move the ton bag to a specified height, and then the first electric push rod 17 drives the block 18 to move away The fixed block 11 moves in the direction of the fixed block 11. When the block 18 is separated from the rotating hook 12, the ton bag will fall down due to its own gravity. The rotating hook 12 will rotate downward under the compression to loosen the sling of the ton bag, and the first torsion spring 13 will be deformed. When the sling of the ton bag is completely separated from the rotating hook 12, the first torsion spring 13 will return to its original state, driving the rotating hook 12 to rotate upward and reset. At this time, the ton bag will perform free fall and fall into the collection frame 3, thereby completing the drop test of the ton bag. By observing the state of the ton bag after the test, it can be judged whether it is qualified. By adjusting the drop height of the ton bag, it can adapt to different test requirements and strengths;When it is necessary to perform a pressure test on the ton bag, repeat the above operation, first hang the ton bag to the lower end of the fixed pipe 6, and add an appropriate amount of material into the ton bag through the fixed pipe 6, and then drive the pressure ring 21 to move downward through the hydraulic cylinder 20, so that the inner side of the pressure ring 21 is separated from the fixed pipe 6, and the pressure ring 21 can drive the rotating cover 22 to move downward. When the rotating cover 22 is separated from the fixed pipe 6, the third torsion spring 23 will return to its original state, driving the rotating cover 22 to rotate upward and close. At this time, the bottom of the pressure ring 21 is flush with the bottom of the rotating cover 22, and can form a complete pressure plate. When the bottom of the pressure ring 21 and the bottom of the rotating cover 22 are in contact with the material in the ton bag, the material in the ton bag will be pushed downward, thereby pressurizing the material in the ton bag, and the hydraulic The cylinder body of the pressure cylinder 20 will be pushed upward due to the reaction force, so that the mounting plate 25 and the pressure sensor 26 can also be pushed upward, and the mounting frame 24 presses the top of the pressure sensor 26, so that the pressure sensor 26 can detect the above thrust and upload the detection data to the external display, so that the value of the pressure applied by the pressure ring 21 and the rotating cover 22 to the material can be known, so that the pressure test of the ton bag can be completed, and the qualification can be judged by observing the state of the ton bag after the test; during the drop test and the pressure test of the ton bag, the blocking cloth 8 is in the unfolded state. If the ton bag is damaged during the test, the blocking cloth 8 can also block the splashing material, so that the material can fall into the collection frame 3 in a concentrated manner, which is convenient for use in the next test. ;

[0033] like Fig.10 As shown, it also includes a second electric push rod 27 and a clamping rod 28. The second electric push rod 27 is symmetrically installed on the front and rear sides of the top of the support frame 2, and the clamping rod 28 is connected to the telescopic rod of the second electric push rod 27, and the clamping rod 28 can be clamped in the clamping groove 1001; when the equipment is performing a pressure test on the ton bag, the clamping rod 28 can be driven by the second electric push rod 27 to move toward the direction close to the connecting rod 10, so that the clamping rod 28 is clamped in the clamping groove 1001, thereby locking the connecting rod 10. When the material in the ton bag is under pressure, the connecting rod 10 will also be subjected to downward pressure. At this time, the clamping rod 28 can distribute the pressure on the connecting rod 10 to the support frame 2, so that the wire rope of the first winch 9 is not subjected to downward pressure, thereby preventing the first winch 9 from being damaged.

[0034] Since the bottom of the collecting frame 3 is a plane, it is difficult for the material on the left side of the collecting frame 3 to fall into the first spiral feeder 4 through the notch thereon, so a material dumping component is designed; Fig.11As shown, the material unloading assembly includes a second winch 29, a connecting plate 30 and a baffle 31. The second winch 29 is symmetrically installed on the upper left side of the collection frame 3. The steel wire ropes of the two second winches 29 slide through the left side of the collection frame 3. The lower right part of the inner side of the collection frame 3 is rotatably connected with the connecting plate 30, and the ends of the steel wire ropes of the two second winches 29 are connected to the left side of the top of the connecting plate 30. The left side of the inner wall of the collection frame 3 is connected with a baffle 31, and the right side of the baffle 31 is an arc surface, which is adapted to the rotation arc of the connecting plate 30 so that the connecting plate 30 When rotating upward, the right side of the baffle 31 can always fit with the left end of the connecting plate 30; when the first screw loader 4 and the second screw loader 5 cooperate to transport the material in the collecting frame 3 to the inside of the fixed pipe 6, the second winch 29 can pull the top left side of the connecting plate 30 upward, so that the connecting plate 30 rotates to an inclined state, thereby being able to dump the material in the collecting frame 3 into the first screw loader 4, facilitating the feeding work of the first screw loader 4, and the baffle 31 can prevent the material inside the collecting frame 3 from falling under the connecting plate 30.

[0035] like Figure 4 As shown, it also includes a fixed plate 32 and a roller 33. Two fixed plates 32 are symmetrically connected to the side of each fixed block 11. A roller 33 is rotatably connected between the two fixed plates 32. The roller 33 corresponds to the blocks 18 one by one, and the roller 33 contacts the top of the corresponding block 18. When the block 18 locks the rotating hook 12, the roller 33 can press the top of the block 18 to prevent the block 18 from tilting upward due to the gravity of the ton bag, thereby preventing the first electric push rod 17 from being damaged.

[0036] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
