Description

Technical Field

[0001] This utility model relates to the field of packaging bag testing technology, specifically a tensile tester with a quick clamping structure. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production of various daily necessities. They are widely used in daily life and industrial production. In order to ensure the effect of later use, existing plastic packaging bags are often subjected to a pull test during the production process to test the tensile strength of the plastic packaging bags.

[0003] A search revealed a utility model patent in China with patent publication number CN218674529U, which discloses a safety testing device for lifting heavy objects from plastic packaging bags. The device generally includes a base plate, a lifting mechanism fixedly mounted on one side of the base plate, a support rod mounted on the lifting mechanism, a tension gauge fixedly mounted at the bottom of the support rod, and a fixing rod mounted at the bottom of the tension gauge. During use, the first and second steps increase the contact area between the device and the plastic bag, improving the fixing effect. Furthermore, the fixed plastic bag is curved between the first and second steps, making it less prone to slippage, further enhancing the fixing effect and effectively preventing the plastic bag from falling off during testing. However, this device has certain shortcomings, such as the two hooks being difficult to adjust, the first and second clamping plates being difficult to replace, and the device being inconvenient to adjust for different packaging bag sizes, resulting in poor applicability. Therefore, we propose a tension tester with a quick-clamping structure. Utility Model Content

[0025] Please see Figures 1-4 A tensile testing instrument with a quick-clamping structure includes a lifting mechanism 1, and further includes:

[0026] The base 2 and the lifting mechanism 1 are fixedly connected to the base 2;

[0027] The testing mechanism is set on the lifting mechanism 1. The testing mechanism includes a tension gauge 3, which is mounted on the lifting mechanism 1. A fixed frame 4 is fixedly connected to the tension gauge 3, and a fixed cylinder 5 is fixedly connected to the fixed frame 4. Two fixed plates 6 are slidably connected inside the fixed cylinder 5. Hooks 7 are fixedly connected to the fixed plates 6. Multiple limiting grooves 8 are opened inside the fixed cylinder 5. A sliding groove is opened on the fixed plate 6 through the opening and the control port. A sliding plate 9 is slidably connected inside the sliding groove. Multiple springs are set between the sliding plate 9 and the sliding groove. A limiting block 10 and a control block 11 are fixedly connected to the sliding plate 9. The limiting block 10 is located in the opening and one of the limiting grooves 8, and the control block 11 is located in the control port. The springs, limiting blocks 10, and sliding plates 9 are used for limiting and fixing. The fixed cylinder 5 and the fixed plates 6 are used to adjust the position of the hooks 7, which improves the applicability.

[0028] The clamping mechanism is mounted on the base 2 and includes a mounting plate 12 and two grooves. The mounting plate 12 is fixedly connected to the base 2, and both grooves are formed on the base 2. The mounting plate 12 is detachably connected to a clamping plate 13 via multiple hand-tightening screws. A slider 14 is slidably connected in the groove, and an electric cylinder 15 is installed between the slider 14 and the groove. The two sliders 14 are detachably connected to a clamping plate 16 via two hand-tightening screws. The clamping plate 13 and the clamping plate 16 are compatible. The hand-tightening screws 1 and 2 are used to facilitate the replacement of the clamping plate 13 and the clamping plate 16, thereby facilitating the clamping of packaging bags of different sizes.

[0029] Multiple stabilizing shafts 17 are fixedly connected inside the slide. Springs are sleeved on the stabilizing shafts 17. The slide plate 9 is slidably connected to the multiple stabilizing shafts 17 to improve the stability of the slide plate 9 when it moves.

[0030] The base 2 has two positioning slots, and two positioning blocks 18 are fixedly connected to the clamping plate 13. The positioning blocks 18 are located in the positioning slots and are used for positioning to facilitate installation and improve stability during clamping.

[0031] Both sliders 14 are provided with positioning grooves 2. Two positioning blocks 2 19 are fixedly connected to the clamping plate 2 16. The positioning blocks 2 19 are located in the positioning grooves 2 for positioning to facilitate installation and improve stability during clamping.

[0032] A baffle 20 is provided inside the groove to serve as a shield.

[0033] It should be further explained that the electric cylinder 15 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be adjusted and operated by those skilled in the art according to the requirements of its instruction manual. It will not be described in detail here. The electric cylinder 15 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operator's operation and control.

[0034] In summary, the working principle and process of this tensile tester with a quick-clamping structure are as follows: First, place the tensile tester at the desired location. When adjustment is needed, press the control block 11. The control block 11 moves the slide plate 9 and the limiting block 10, causing the limiting block 10 to move out of the limiting groove 8. The slide plate 9 will compress the spring. Then, slide the fixing plate 6. After adjusting to the desired position, release the control block 11. The spring will return, and the limiting block 10 will enter another limiting groove 8, thus completing the adjustment. Adjust the position of the pair of hooks 7. When it is necessary to adjust the clamps 13 and 16, simply rotate and remove the first and second hand screws, and then take out the clamps 13 and 16 for replacement. In use, place one side of the packaging bag on the clamp 13, start the electric cylinder 15, and the electric cylinder 15 drives the slider 14 to move, so that the clamp 16 and the clamp 13 hold the packaging bag. Then hang the packaging bag on the two hooks 7, and then use the lifting mechanism 1 to raise it. In this way, the tension gauge 3 can test the packaging bag.

[0035] The lifting mechanism 1 involved in this solution is a technology already authorized by the utility model patent disclosed in Chinese Patent Publication (Announcement) No. CN218674529U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in its applicability to testing of packaging bags of different specifications and improving its applicability. Therefore, this patent will not elaborate on its internal structure and working principle.

[0036] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
