Description

Technical Field

[0001] The invention relates to the technical field of container bag detection, and in particular to a detection device for high-toughness flexible container bags. Background Art

[0002] Flexible bulk bags, also known as flexible containers or ton bags, are a type of medium-sized bulk container and a type of collective packaging. In the production process, the toughness test of bulk bags is crucial. Its main purpose is to evaluate the ability of bulk bags and their key components to resist damage under stress or specific conditions. Usually, the toughness test is carried out by load inspection, which can be divided into two methods: filler test and hydraulic test. The filler test simulates the actual use scenario by pressing down after filling the bulk bag with fillers such as sand; the hydraulic test directly applies pressure to the bulk bag for testing.

[0003] However, in actual operation, the filler detection method has certain limitations. First, before each test, the container bag needs to be filled with fillers in advance, or after the previous container bag is tested, the fillers in it need to be introduced into the next container bag through the bottom incision for testing. This process is not only lengthy, but also because the bottom of the previous container bag will be torn due to tearing after the test, the size of the crack is inconsistent, and the fillers are not easy to discharge, resulting in the need for operators to perform further opening operations. In addition, the weight of the fillers inside the container bag is relatively large, and there are certain safety hazards when the operator performs the opening operation at the bottom, which not only prolongs the test preparation time, but also affects the test efficiency.

[0004] Therefore, it is particularly necessary to develop a high-toughness flexible container bag detection device, by optimizing the detection process, thereby simplifying the operation steps, improving the detection efficiency, and ensuring the safety of the operators. Summary of the invention

Slide rods are slidably embedded in the arc grooves, and the slide rods are connected to the corresponding slings.

[0009] Furthermore, a vacuum cleaner is installed between the outer walls of the material hopper, and a group of dust hoods spaced apart from each other are provided between the two front and rear opposite brackets.

Therefore, they cannot be understood as limitations on the present invention.

[0029] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment 1: A detection device for a high-toughness flexible container bag, such as Figure 1-Figure 7 As shown, including: There are four brackets 1, which are evenly distributed in the circumferential direction at the four positions. A movable frame 11 driven by a driving component to be lifted and lowered slides between the brackets 1. The movable frame 11 adopts a cross-shaped frame structure, and each branch is provided with a straight groove. The driving component is installed on each bracket 1. A sling 111 arranged in the four directions slides on the movable frame 11, so that the sling 111 is slidably embedded in the straight groove corresponding to each branch, and the position can be flexibly adjusted to meet the lifting requirements of different sizes of bulk bags 100. A weight sensor 112 for detecting the carrying weight of the bulk bag 100 is provided on the sling 111; The driving assembly includes a spur rack 12 arranged at each end of the mobile frame 11. The spur rack 12 is located inside the corresponding bracket 1, and each bracket 1 is equipped with an electric gear 13 meshing with the adjacent spur rack 12. The electric gear 13 drives the driving gear to rotate, and converts the rotational motion into linear motion through meshing with the spur rack 12, thereby driving the mobile frame 11 to rise and fall smoothly.

[0031] The hydraulic cylinder 2 is fixedly installed in the middle of the mobile frame 11 and the telescopic end is arranged downward. A pressure plate 21 with a built-in pressure sensor is connected to the telescopic end of the hydraulic cylinder 2. The hydraulic cylinder 2 drives the pressure plate 21 to move to simulate the external pressure applied to the container bag 100. At the same time, the pressure sensor monitors the force in real time to detect the toughness and pressure resistance of the container bag 100. A filling mechanism 3 for filling the container bag 100, the filling mechanism 3 includes a mounting frame 31 located below the mobile frame 11, so that the mounting frame 31 is in the middle area between the four legs 1, and a left-right symmetrical accumulation hopper 32 is arranged inside the mounting frame 31, and the accumulation hopper 32 is used to load the filler for detection, and two guide cylinders 33 are arranged between the brackets 1, and the two guide cylinders 33 are arranged in a left-right symmetrical layout, and the guide cylinders 33 are respectively connected to the same side accumulation hopper 32, and an electric auger 34 for conveying the filler from bottom to top is arranged inside the guide cylinder 33, and a discharge pipe 35 is connected to the upper end of the guide cylinder 33; It can be seen that the hopper 32, as a carrier for accommodating fillers, can supply fillers to the corresponding guide cylinder 33, and then the electric auger 34 pushes the fillers for transportation from bottom to top, so that the fillers move to the upper end of the guide cylinder 33 and are discharged from the discharge pipe 35, thereby completing the loading of the container bag 100 to meet the detection conditions of the container bag 100. During this process, the weight sensor 112 monitors the weight of the load in real time to ensure that the loading can be stopped in time when the set value is reached. Subsequently, the hydraulic cylinder 2 drives the pressure plate 21 to apply pressure to the loaded container bag 100 to simulate the actual load-bearing scenario. At the same time, the pressure sensor monitors the pressure size in real time and accurately feeds back the performance data of the container bag 100 until the container bag 100 breaks and reaches its maximum bearing limit; then, the fillers dropped after the container bag 100 breaks will fall back into the hopper 32 to provide materials for the next round of detection, forming a cyclic and efficient loading and detection process, effectively simplifying the traditional lengthy and complicated loading steps, and significantly improving the detection efficiency.

[0032] The slitting mechanism 4 includes guide sleeves 42 distributed around the mounting frame 31. There are four guide sleeves 42. One end of the guide sleeves 42 passes through the corresponding material hopper 32 and tends to be arranged centrally. The tail end of the guide sleeve 42 extends to the inside of the adjacent bracket 1. A displacement rod 43 is slid inside the guide sleeve 42. The opposite end of the displacement rod 43 is provided with a cutting knife 44 located directly below the moving frame 11. The blade of the cutting knife 44 is arranged upward. A pulling assembly is provided at the tail end of the displacement rod 43. A push rod 41 that contacts and adapts to the adjacent pulling assembly is provided at the end of the moving frame 11.

[0033] Specifically, in order to ensure that the torn container bag 100 can discharge the filler smoothly, the push rod 41 is moved in coordination with the moving frame 11, so that the push rod 41 can contact and push the corresponding pulling component to move, drive the connected displacement rod 43 and the cutting knife 44 to move, and prompt each cutting knife 44 to move from a concentrated state to an expanded state around, so as to further cut the rip of the torn container bag 100, thereby ensuring the smooth outflow of the filler; from then on, through the coordinated cooperation of various components, the automatic opening operation is realized, which effectively replaces manual intervention, not only reduces the safety risks caused by heavy object operation, but also further improves the safety and efficiency of the operation.

[0034] like Figure 6 and Figure 7As shown, the pulling assembly includes a pull rope 46 arranged at the tail end of each displacement rod 43, and the pull rope 46 slides through the tail end of the corresponding guide sleeve 42. An elastic member 45 is arranged between the inner wall of the guide sleeve 42 and the tail end of the corresponding displacement rod 43. In this embodiment, the elastic member 45 is a spring, which is used to provide the necessary elastic force for resetting the displacement rod 43, and the end of the pull rope 46 is connected to a stop block 47 slidably embedded in the bracket 1. The stop block 47 can move up and down along the bracket 1, so as to cooperate with the lifting and lowering action of the mobile frame 11, so as to promote the contact and cooperation between the stop block 47 and the corresponding push rod 41, and the pull rope 46 is pulled by the downward movement of the stop block 47, so as to drive the connected displacement rod 43 to slide in the guide sleeve 42, and the elastic member 45 is deformed, so as to drive the cutting knife 44 to move and open the container bag 100.

[0035] like Figure 7 As shown, a group of rollers 421 arranged in an upper and lower interval arrangement are rotatably disposed at the end of the guide sleeve 42 , and the pull rope 46 is located between two corresponding rollers 421 to assist the pulling action of the pull rope 46 .

[0036] like Figure 4 and Figure 5 As shown, support rods 36 are provided on both sides of the end of the discharge pipe 35 , and the discharge pipe 35 is a corrugated telescopic tube structure. The support rods 36 are connected to the moving frame 11 and can cooperate with the moving frame 11 to extend the discharge pipe 35 .

[0037] When the toughness and strength of the container bag 100 need to be tested, the filler required for loading is first placed in the hopper 32, and then the container bag 100 is placed between the slings 111 so that the container bag 100 is directly below the mobile frame 11. The drive assembly is started to drive the mobile frame 11 to rise and fall, ensuring that there is a sufficient distance between the bottom of the container bag 100 and the cutting knife 44 to avoid contact. At the same time, the support rod 36 moves with the moving frame 11, driving the discharge pipe 35 to expand and contract, so that the bottom end of the discharge pipe 35 is always higher than the bag mouth of the container bag 100 for subsequent loading, and then the filling mechanism 3 is started, and the filling material in the storage hopper 32 is transported to the discharge pipe 35 through the electric auger 34 to load the container bag 100. The weight sensor 112 monitors the weight in real time. After reaching the set value, the background can control the electric auger 34 to stop filling, and then drive the pressure plate 21 to press down the loaded container bag 100 through the hydraulic cylinder 2. The pressure sensor feeds back the applied pressure value in real time, and the staff can observe the monitoring data through the background; if only the pressure resistance performance needs to be directly tested, the filling step can be omitted, and the hydraulic cylinder 2 and the pressure plate 21 can be used directly to perform a pressure test on the empty container bag 100; After the container bag 100 reaches the maximum bearing capacity and then ruptures, the test can be stopped, and the movable frame 11 drives the container bag 100 to descend, so that the push rod 41 contacts the stop block 47, and the stop block 47 slides down along the bracket 1 to pull the pull rope 46, driving the displacement rod 43 to move along the corresponding guide sleeve 42. At this time, the elastic member 45 is deformed, and the cutter 44 moves synchronously and cuts the bottom of the container bag 100 to assist the smooth discharge of the filler, completing this test, and finally removing the empty container bag 100. Repeat the above operation to start the next round of testing.

[0038] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 8 As shown, the mobile frame 11 is provided with a shaking mechanism 5 for assisting the unloading of the container bag 100. The shaking mechanism 5 includes support plates 51 circumferentially arranged on each branch at the top of the mobile frame 11. There are four support plates 51. A turntable 52 rotates between the support plates 51. A gear ring 53 is arranged at the inner circle position of the turntable 52. An electric gear 54 is installed on the mobile frame 11, and a driving gear meshing with the gear ring 53. The turntable 52 is provided with an arc groove 521 adapted to the layout and number of the sling 111. Slide rods 55 are slidably embedded in the arc grooves 521, and the slide rods 55 are connected to the corresponding slings 111.

[0039] Specifically, the electric gear 2 54 drives the connected driving gear to mesh with the toothed ring 53, thereby driving the turntable 52 to rotate between the support plates 51. When the turntable 52 rotates, the sliding cooperation between the arc groove 521 and the slide bar 55 pushes the sling 111 connected to the slide bar 55 to slide along the corresponding straight groove. This action causes the lifted container bag 100 to twist, assisting it in unloading, and further improving the overall discharge efficiency.

[0040] like Fig. 9 As shown, a vacuum cleaner 6 is fixedly installed between the rear outer walls of the material accumulating hopper 32, and a group of dust hoods 61 spaced apart from each other are provided between the two front and rear opposite brackets 1. The upper and lower dust hoods 61 correspond to the bag opening and bag bottom positions of the container bag 100, respectively. The dust hood 61 and the dust inlet of the vacuum cleaner 6 are connected by a connecting pipe 62. Through the cooperation of the vacuum cleaner 6 and the dust hood 61, the dust or debris generated during the test can be effectively collected, and the loading and unloading areas can be dusted respectively to ensure all-round coverage, avoid dust diffusion, keep the working environment clean, and provide more tidy operating conditions for the detection process.

[0041] like Fig.10As shown, a consolidation frame 7 is provided on the top of the mounting frame 31 for extending the outer position of the mounting frame 31 to prevent the filler from spilling out when the container bag 100 is unloaded. A cross 71 is provided in the consolidation frame 7 in a staggered layout with the cutter 44. The cross 71 can provide support and enhance stability during the unloading process of the container bag 100. Without affecting the layout of the cutter 44, additional support is provided for the bottom of the container bag 100, thereby improving the safety of the device and providing a more stable operating environment for the testing process.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
