Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric performance testing, and particularly to a performance testing device for non-woven fabrics. Background Art

[0002] Non-woven fabric is a new type of fiber product directly made from polymer chips, staple fibers or filaments through various web forming methods and consolidation techniques, which has the characteristics of low cost and the ability to adjust material properties according to requirements, and is widely used in many fields such as medical and health, environmental protection filtration, geotechnical construction, agriculture, packaging, etc.

[0003] During the production process of non-woven fabrics, in order to ensure that non-woven fabrics meet specific application standards, a series of performance tests need to be carried out on non-woven fabrics. Among them, the tensile strength test of non-woven fabrics is to evaluate key indicators such as the tensile force value and elongation rate when the non-woven fabric is stressed until it breaks.

[0004] The current testing equipment can conduct batch testing on non-woven fabrics. However, after each test is completed, manual unloading and loading are required. This process is relatively time-consuming. Especially when dealing with a large number of non-woven fabrics, manual operation will significantly increase the overall testing cycle. Specifically, manual unloading and loading will not only prolong the time of a single test, but also may reduce the overall production efficiency, forming a process bottleneck. Summary of the Invention

[0005] In view of this, the present invention provides a performance testing device for non-woven fabrics, which can overcome the disadvantages that manual unloading and loading will not only prolong the time of a single test, but also may reduce the overall production efficiency.

[0029] Refer to Figures 1 - 11 , a performance testing device for non-woven fabrics, including a base 1, a circular plate 2, a servo motor 3, a rotating plate 4, a first placing block 7, a first sliding shaft 8, a second placing block 10, a pressure sensor 11, a loading mechanism, and a clamping mechanism. The lower part of the base 1 is circumferentially and evenly spaced with mounting holes 15. The top of the base 1 is bolted with a circular plate 2. The middle of the circular plate 2 is bolted with a servo motor 3. The output shaft of the servo motor 3 is connected with a rotating plate 4. The rotating plate 4 is circumferentially and evenly spaced with arc-shaped openings 5. The top of the circular plate 2 is circumferentially and evenly spaced with a first chute 6. The first placing blocks 7 are slidably connected in the first chutes 6. The tops of the first placing blocks 7 are all connected with a first sliding shaft 8. The first sliding shafts 8 are located in the arc-shaped openings 5. The top of the circular plate 2 is circumferentially and evenly spaced with a second chute 9. The arc-shaped openings 5, the first chutes 6, and the second chutes 9 are the same in number. The second placing blocks 10 are slidably connected in the second chutes 9. Pressure sensors 11 are bolted on one side of the second chutes 9 close to the first placing blocks 7. The second placing blocks 10 are in contact with the pressure sensors 11. The loading mechanism is used to load non-woven fabrics into the first placing blocks 7 and the second placing blocks 10. The clamping mechanism is used to clamp the non-woven fabrics in the first placing blocks 7 and the second placing blocks 10.

[0030] Refer to Figures 5 - 9 , the loading mechanism includes a rotating ring 121, an internal gear ring 122, a stepping motor 123, a gear 124, a placing plate 125, and a supporting component. The rotating ring 121 is rotatably connected to the top of the circular plate 2. The internal gear ring 122 is connected inside the rotating ring 121. The stepping motor 123 is bolted to the bottom of the circular plate 2. The output shaft of the stepping motor 123 is key-connected with a gear 124. The gear 124 meshes with the internal gear ring 122. The tops of the rotating ring 121 are circumferentially and evenly spaced with placing plates 125. The supporting component is used to support the non-woven fabrics on the placing plates 125.

[0031] Refer to Figures 5 - 9, the support assembly includes a slider 126, a support block 127 and a second sliding shaft 128. Sliders 126 are slidably connected to both sides of the placement plate 125. Support blocks 127 are evenly spaced and connected to the top of the sliders 126. Second sliding shafts 128 are connected to the sliders 126. The second sliding shafts 128 slidably penetrate through the bottom of the sliders 126. Two annular guide grooves 129 are formed at the top of the circular plate 2. Both of the two annular guide grooves 129 are located on the periphery of the servo motor 3, and the rotating ring 121 is located between the two annular guide grooves 129. The second sliding shafts 128 are located in the annular guide grooves 129. The positions of the annular guide grooves 129 close to the first placement block 7 and the second placement block 10 are V-shaped.

[0032] Referring to Figure 10 and Figure 11 , the clamping mechanism includes a U-shaped tube 131, a piston rod 132, a clamping block 133, an annular tube 134, a gas guide tube 135 and an air inlet tube 136. U-shaped tubes 131 are connected to the bottoms of both the first placement block 7 and the second placement block 10. Piston rods 132 are slidably and sealingly connected to both sides inside the U-shaped tubes 131. The upper ends of the two piston rods 132 in the same U-shaped tube 131 are commonly connected to a clamping block 133. Rubber layers are provided at the top of the clamping block 133, the inner top of the first placement block 7 and the inner top of the second placement block 10. The rubber layers have a relatively high coefficient of friction, which can provide better gripping force and stability on the contact surface, ensuring a more secure clamping effect. An annular tube 134 is connected to the upper part inside the base 1. A gas guide tube 135 is connected between the annular tube 134 and the U-shaped tube 131, and both the annular tube 134 and the U-shaped tube 131 communicate with the gas guide tube 135. An air inlet tube 136 is communicated with the right side of the annular tube 134. The air inlet tube 136 penetrates through the right side of the base 1.

[0033] The staff can place the bolt into the mounting hole 15 and install the base 1 on the ground through the bolt to improve the stability of the base 1. Then, place the non-woven fabric into the placing plate 125, and the support blocks 127 support both ends of the non-woven fabric. Then, control the output shaft of the stepping motor 123 to rotate, driving the gear 124 to rotate. The gear 124 drives the internal gear ring 122 to rotate, the internal gear ring 122 drives the rotating ring 121 to rotate, and the rotating ring 121 drives the placing plate 125 to rotate, rotating the non-woven fabric into the placing block one 7 and the placing block two 10. The support blocks 127 will also move into the placing block one 7 and the placing block two 10. The rotation of the placing plate 125 can also drive the sliding shaft two 128 to rotate, and the sliding shaft two 128 slides in the annular guide groove 129. When the sliding shaft two 128 slides to the V-shaped position of the annular guide groove 129, the sliding shaft two 128 will slide towards the direction close to the rotating ring 121, and the support block 127 will slide towards the direction close to the rotating ring 121 accordingly. The support block 127 moves out of the placing block one 7 and the placing block two 10, and the support block 127 no longer supports both ends of the non-woven fabric. Both ends of the non-woven fabric will fall onto the top of the clamping block 133. At this time, turn off the stepping motor 123, then connect the external air source to the air inlet pipe 136. Air enters the air inlet pipe 136, and the air enters the annular pipe 134 through the air inlet pipe 136. Subsequently, the air enters the U-shaped pipe 131 through the air guide pipe 135 and pushes the piston rod 132 to move upward. The piston rod 132 drives the clamping block 133 to move upward, and the clamping block 133 clamps the non-woven fabric in the placing block one 7 and the placing block two 10. Then, control the output shaft of the servo motor 3 to rotate, driving the rotating plate 4 to rotate. The rotating plate 4 pulls the sliding shaft one 8 through the arc-shaped opening 5, causing the sliding shaft one 8 to move towards the direction close to the servo motor 3, so that the placing block one 7 can move towards the direction close to the servo motor 3. The placing block one 7 can pull the non-woven fabric to conduct a tensile strength test. The non-woven fabric pulls the placing block two 10, and the placing block two 10 presses the pressure sensor 11. The pressure sensor 11 senses the pressure value. The pressure sensor 11 can be connected to an external computer, and the pressure sensor 11 feeds back the data to the external computer. The tensile strength of the non-woven fabric can be obtained through the external computer. After all the non-woven fabric clamped by the clamping block 133 breaks, control the output shaft of the servo motor 3 to rotate in the reverse direction, driving the rotating plate 4 to rotate in the reverse direction. The rotating plate 4 pulls the sliding shaft one 8 through the arc-shaped opening 5, causing the sliding shaft one 8 to move away from the servo motor 3, so that the placing block one 7 can move away from the servo motor 3 to reset the placing block one 7. Then, disconnect the air source from the air inlet pipe 136. The clamping block 133 moves downward under its own gravity to release the broken non-woven fabric. Then, control the output shaft of the stepping motor 123 to rotate, driving the placing plate 125 to rotate, rotating the untested non-woven fabric into the placing block one 7 and the placing block two 10. The support blocks 127 will also move into the placing block one 7 and the placing block two 10 and push the broken non-woven fabric out of the placing block one 7 and the placing block two 10. At the same time,The second sliding shaft 128 will slide out from the V-shaped position of the annular guide groove 129, and the second sliding shaft 128 will slide away from the rotating ring 121. Accordingly, the support block 127 will slide away from the rotating ring 121. Subsequently, the next second sliding shaft 128 slides to the V-shaped position of the annular guide groove 129, and the second sliding shaft 128 will slide towards the rotating ring 121. Accordingly, the support block 127 will slide towards the rotating ring 121. The support block 127 moves out from the first placing block 7 and the second placing block 10, and the support block 127 no longer supports both ends of the non-woven fabric. Both ends of the non-woven fabric will fall onto the top of the clamping block 133. At this time, the stepping motor 123 is turned off, and the above operations are repeated to perform batch testing on the non-woven fabric, and automatic unloading and loading can be achieved, shortening the testing time and improving the overall production efficiency.

[0034] Referring to Figure 1 and Figure 8 , it further includes a protective cover 142. An annular placing groove 141 is formed at the top of the circular plate 2, and the protective cover 142 is placed in the annular placing groove 141. The protective cover 142 can block the broken non-woven fabric to prevent the broken non-woven fabric from flying out and hurting people. The top of the protective cover 142 is made of a transparent material to facilitate observing the testing condition of the non-woven fabric.

[0035] Obviously, the described embodiments above are only a part of the embodiments of the present invention, rather than all of the embodiments. It only expresses the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be thus construed as a limitation to the scope of the patent of the present invention.

[0036] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, quantity increases or decreases, improvements and substitutions can still be made. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
