[0001] The utility model relates to the technical field of non-woven fabric strength detection, in particular to a tensile strength detection device for a pull-resistant non-woven fabric bag. Background Art

[0002] With the improvement of people's living standards, people are using more and more non-woven fabrics, among which non-woven fabrics are made into non-woven bags, which is a very wide application. Non-woven bags have good degradation ability, less pollution to the environment, and are more durable. Non-woven bags have been widely used in supermarkets to hold goods. When people use non-woven bags to hold goods, they need to understand how many items the non-woven bags can withstand. Therefore, a tensile strength testing device for non-woven environmentally friendly bags is proposed.

[0003] An existing patent (Announcement No.: CN111811940A) discloses a tensile strength testing device for non-woven environmentally friendly bags. When the drive motor stops working, the coil stops rotating, and the current in the external wire of the solenoid disappears, causing the extrusion plate to move left and touch the first switch to start the suction fan. The broken non-woven fabric is unrestrained and is sucked into the collection box below by the suction fan. After the test, the drive motor is automatically turned off. The test results are displayed on the scale on the connecting column, and the waste materials after testing can be automatically collected. In the process of implementing this solution, the following problems were found in the existing technology and have not been effectively solved:

[0004] Its structure is complex and the production cost is high, and it occupies a large area, which is not suitable for large-scale promotion. In addition, the test results of the non-woven bag cannot be intuitively viewed during the test process, which makes the test operation complicated and affects its use. Summary of the Invention

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment of a tensile strength testing device for a non-woven bag with a resistant pull-up structure, comprising a device body 1 and a drive motor 12. A side plate 2 is connected to the top of the device body 1, and an insertion rod 3 is connected to the top of the side plate 2. The insertion rod 3 is fixed by the side plate 2 to complete the position fixing work. A limiting rod 5 is connected to the center of the insertion rod 3. The limiting rod 5 fixes the insertion rod 3 to prevent the insertion rod 3 from shaking. A first magnet 4 is connected to the bottom of the insertion rod 3.

[0030] The center of the driving motor 12 is connected to an adjusting screw rod 11, and the right side of the adjusting screw rod 11 is connected to an auxiliary rod 13. The adjusting screw rod 11 is limited by the auxiliary rod 13 to prevent it from shaking. Threaded blocks 10 are connected on both sides of the adjusting screw rod 11, and the top of the threaded block 10 is connected to a base plate 6. The base plate 6 is used to assist in fixing the non-woven bag for detection work. A connecting rod 15 is connected above the base plate 6, and a linkage block 9 is connected above the connecting rod 15. The linkage block 9 cooperates with the connecting rod 15 to ensure that the linkage block 9 can be lifted and lowered stably. A shock absorber 7 is connected to the bottom of the linkage block 9, and an anti-sliding block 8 is connected to the front side of the linkage block 9. The anti-sliding block 8 is used for auxiliary fixation to prevent the non-woven bag from detaching.

[0031] See the attached drawings in the specification Figure 1-4 The connection between the device body 1 and the side panel 2 is a hot melt connection. Insertion grooves are evenly and equidistantly distributed above the side panel 2. The connection between the side panel 2 and the insertion rod 3 is a sliding connection. The insertion rod 3 is fixed and limited by the side panel 2, which makes it easy to adjust the position of the insertion rod 3.

[0032] See the attached drawings in the specification Figure 1-4 The insertion rod 3 and the first magnet 4 are installed in an integrated manner. The first magnet 4 and the linkage block 9 are adsorbed on each other. The connection between the insertion rod 3 and the limit rod 5 is a sliding connection. The linkage block 9 is driven to rise and fall by the first magnet 4 to automatically fix the non-woven bag, and the limit rod 5 is used to limit the position to prevent the first magnet 4 from moving.

[0033] See the attached drawings in the specification Figure 1-4 The bottom plate 6 and the threaded block 10 are installed in an integrated manner. The bottom plate 6 is symmetrically distributed on both sides above the device body 1. A measuring ruler 14 is provided on the front side of the bottom plate 6. The measuring ruler 14 is installed in an integrated manner with the device body 1. The bottom plate 6 is driven to move by the threaded block 10, thereby moving inside the measuring ruler 14 to perform tensile testing of the non-woven bag.

[0034] See the attached drawings in the specification Figure 1-4The linkage block 9 is connected to the connecting rod 15 in a sliding manner. The linkage block 9 forms a spring reset structure with the bottom plate 6 through the shock absorber 7. The linkage block 9 is connected to the anti-sliding block 8 in a hot melt manner. The linkage block 9 cooperates with the shock absorber 7 to ensure that the linkage block 9 can automatically release the limit fixation of the non-woven bag, and the anti-sliding block 8 improves the fixing effect to prevent the non-woven bag from falling off.

[0035] See the attached drawings in the specification Figure 1-4 The threaded block 10 and the adjusting screw 11 are connected by threaded connection. The threads on both sides of the adjusting screw 11 are in opposite directions. The adjusting screw 11 and the auxiliary rod 13 are connected by rotation. The adjusting screw 11 is used to make the threaded block 10 move towards or away from each other, ensuring that the directions of movement toward both sides are the same, thereby completing the detection work.

[0036] Working principle: When in use, first, place the two sides of the non-woven bag that needs to be tested above the bottom plate 6, then turn on the switch of the driving motor 12, so that the driving motor 12 drives the adjusting screw 11 to rotate, and then the adjusting screw 11 and the threaded block 10 perform threaded movement, so that the threaded block 10 drives the bottom plate 6 to move toward both sides, and the bottom plate 6 drives the linkage block 9 to move through the connecting rod 15 during the movement. When the linkage block 9 moves toward the outside, it is separated from the adsorption connection with the first magnet 4, and then under the pulling force of the shock absorber 7, the linkage block 9 descends, and at the same time drives the anti-sliding block 8 to descend, so that the anti-sliding block 8 is fixed on both sides of the non-woven bag. As the bottom plate 6 continues to move, it pulls the non-woven bag to move. When it reaches the limit, the tensile strength is checked according to the position of the bottom plate 6 reaching the measuring ruler 14;

[0037] As mentioned above, after completing the tensile test, the driving motor 12 drives the adjusting screw 11 to rotate in the opposite direction, so that the base plate 6 is reset. When the base plate 6 drives the linkage block 9 to move to the bottom of the first magnet 4, the first magnet 4 adsorbs the linkage block 9, so that the linkage block 9 moves upward along the connecting rod 15 until it is adsorbed by the first magnet 4. At this time, the linkage block 9 releases the limit fixation of the non-woven bag. When the size of the non-woven bag changes and the first magnet 4 cannot be adapted, the limit fixation of the insertion rod 3 can be released by pulling out the limit rod 5, and then the position of the insertion rod 3 can be changed to ensure that the first magnet 4 can adapt to non-woven bags of different sizes.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
