Description

Technical Field

[0001] The invention relates to a container bag performance detection technology, and in particular to a stretching test device for an environment-friendly container bag. Background Art

[0002] FIBC (Flexible Intermediate Bulk Container), also known as flexible bulk bag, ton bag, space bag, etc., has many English translations. It is a kind of container unit equipment. With a crane or forklift, it can realize container unit transportation. It is suitable for transporting bulk powder and granular materials. FIBC is a flexible transport packaging container, widely used in the transportation and packaging of powdered, granular and blocky items such as food, grains, medicines, chemicals, and minerals. Developed countries generally use FIBC as a packaging product for transportation and warehousing.

[0003] A Chinese invention patent with publication number CN118130225A discloses a tensile test device for woven bags. The tensile test device for woven bags can sense the air pressure in the top air hood through a pressure sensing plate. The air pressure in the top air hood is related to the overall air permeability of the woven bag sample. When the air pressure in the top air hood increases, the pressure sensing plate will rise under the action of pressure. Since the air intake pressure of the bottom air hood is constant, the extended length of the feedback column can reflect the air permeability of the woven bag sample in the current state. The elastic ratchet part has the function of preventing the feedback column from retracting. It can still maintain its maximum extended position after the measurement is completed, which is convenient for reading. The feedback column can be locked and released through a rotatable guide limit sleeve. After the reading is completed, the feedback column can be allowed to drop and retract by rotating the guide limit sleeve.

[0004] When the existing equipment is in use, it is impossible to perform synchronous testing on container bags from different batches or manufacturers, which affects the accuracy of the test results and causes deviations in the comparison results. At the same time, when the container bag is tested, its inner cavity is in a fluffy state, and only the two sides of the container bag are fixed. When testing, there is a difference between the data obtained and the actual data, and it is impossible to test the load-bearing capacity of the inner cavity of the container bag.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] At the same time, the positions of the two sliders 15 can be adjusted by the slide bar 14, and then the handle of the container bag can be fixed in cooperation with the stretching component 3.

[0043] The connecting plate 267 on the outer surface of the movable rod 264 is connected to the support block 231, so that the support block 231 and the arc block 268 move synchronously, and the surrounding diameter of the arc block 268 is larger than the surrounding diameter of the support block 231, which is convenient for installing and taking out the container bag.

[0044] Furthermore, a power piece 265 is disposed at the upper end of the movable block 263 , and an output end of the power piece 265 is connected to another symmetrically disposed movable block 263 .

[0046] Furthermore, a guide groove 266 corresponding to the movable rod 264 is formed at the lower end of the inner cavity of the cylinder 26 , and the inner wall of the guide groove 266 is slidably connected to the outer surface of the movable rod 264 .

[0047] Specifically, the guide groove 266 is used to limit the movable rod 264 so as to prevent the movable rod 264 from falling off when moving, thereby ensuring the stability of the movable rod 264.

[0049] A first disc 34 is slidably mounted on the outer surface of the sliding rod 33 , and a telescopic column 35 is disposed at the lower end of the first disc 34 .

[0050] In this embodiment, an elastic component such as an elastic block is provided at the upper end of the first disc 34, and the telescopic column 35 is composed of a cylinder and a circular tube. The inner wall of the circular tube is slidably connected to the outer surface of the cylinder, and the end of the circular tube is connected to the first disc 34, and the end of the cylinder is connected to the second disc 37.

[0052] Specifically, the elastic member 36 is an elastic member such as a spring, and is used to support the first disc 34 and the second disc 37, and cooperate with two clamping blocks 38 to fix the handle of the container bag, thereby limiting the container bag.

[0053] Furthermore, a rotating member 39 is disposed on one side of the limiting plate 32 , and an output end of the rotating member 39 passes through and extends to the other end of the limiting plate 32 . Meanwhile, a rotating rod 391 is disposed on the output end of the rotating member 39 .

[0054] An extrusion block 392 is disposed on the outer surface of the rotating rod 391 , and the outer surface of the extrusion block 392 is in contact with the lower end of the second disc 37 .

[0055] Specifically, the rotating member 39 is a device with power output such as a motor, and is connected to an external control device. When the rotating member 39 is started, it synchronously drives a rotating rod 391 arranged at its output end to rotate, and when the rotating rod 391 rotates, it drives an extrusion block 392 arranged on the outer surface of the rotating rod 391 to rotate, wherein the cross-section of the extrusion block 392 is elliptical, so that when the extrusion block 392 rotates, it pushes the second disc 37 to move up and down, thereby simulating the state of the container bag under a bumpy state, and monitoring the container bag through an externally arranged detection device, and the detection device is connected to the external control device.

[0056] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
