[0030] For further information, see Figure 8 A method for preparing a high-wear-resistant and high-strength non-woven fabric, which is used to prepare the high-wear-resistant and high-strength non-woven fabric, comprises the following steps: S1: Use high-strength fiber as raw material through spinning process to form the matrix layer; S2: uniformly coating wear-resistant particles on the base layer; S3: using an adhesive to fix the wear-resistant particles on the base layer to form a wear-resistant coating; S4: curing the base layer coated with the wear-resistant coating to obtain a finished product.

[0031] Specifically, by introducing wear-resistant particles and an optimized adhesive system, the non-woven fabric has excellent wear resistance, which is particularly suitable for application scenarios that require frequent friction or wear, such as industrial protective clothing, furniture covering materials, etc.

[0032] The use of high-strength fibers as the matrix material gives the non-woven fabric higher mechanical strength, enabling it to withstand greater tensile and tearing forces, thus extending the service life of the product.

[0033] In addition to the basic wear-resistant and high-strength properties, different functional layers (such as waterproof, fireproof, and antibacterial) can be added according to specific application requirements to meet a wider range of application scenarios.

[0035] Specifically, the added high-strength fiber material is processed into a corresponding matrix layer through the spinning device 101, and then the wear-resistant particles are coated through the abrasive output box 103 arranged in the processing channel 102 in cooperation with the spraying rack 104, and then the adhesive is sprayed through the glue coating component, and finally the final high-wear-resistant and high-strength non-woven fabric product is obtained through curing treatment; The abrasive output box 103 stores corresponding wear-resistant particles, and the spray rack 104 is connected to the discharge port of the abrasive output box 103, so that the wear-resistant particles can be guided to the surface of the corresponding substrate layer through the spray rack 104, thereby completing the coating of the wear-resistant particles on the surface of the substrate layer. The spray rack 104 is slidably provided with two material control slides 105, and the two material control slides 105 are driven by the regulating cylinder 106. The corresponding material control slides 105 are driven by the regulating cylinder 106 to slide in the spray rack 104, so that the left and right sides of the spray outlet of the spray rack 104 can be adjusted, so that the operator can adjust the spray width of the wear-resistant particles of the spray rack 104 according to the actual width of the non-woven fabric substrate layer. At the same time, the material receiving box 107 is also provided at the bottom of the spray rack.

When the sliding motor 203 drives the sliding screw 202 to rotate, the sliding baffle 201 will slide under the drive of the sliding screw 202, thereby changing the discharge gap size of the material spray outlet of the spray rack 104, so that the user can adjust the actual spray outlet size of the spray rack 104 according to actual conditions; The scraper frame 204 is arranged at the rear side of the spray frame 104, and the scraper frame 204 is driven by the electric push rod 205. The user can drive the scraper frame 204 to slide up and down at the rear side of the spray frame 104 through the electric push rod 205, thereby changing the scraping height of the scraper frame 204, so that the scraper frame 204 can scrape off the excess wear-resistant particles coated on the surface of the base layer to ensure the uniform coating of the wear-resistant particles on the surface of the body layer, and the excess wear-resistant particles scraped off by the scraper frame 204 can be recycled through the set material collecting box 107.

[0038] Furthermore, the paint rack 302 is connected to the processing channel 102 through the adjusting component; the glue discharging device 301 is installed on one side of the paint rack 302; the two baffle plates 303 are slidably installed on both sides of the paint rack 302; the intercepting component is connected to the paint rack 302, and is used to adjust the spraying area of ​​the paint rack 302; the adjusting component is connected to the processing channel 102, and is used to adjust the spraying position of the paint rack 302.

[0039] Furthermore, the shielding slide 304 is slidably installed on one side of the paint rack 302; the driving screw 305 is threadedly connected to the shielding slide 304 and rotatably installed on one side of the paint rack 302; the output shaft of the driving motor 306 is connected to the driving screw 305, and the driving motor 306 is fixedly installed on one side of the paint rack 302; the side baffles 307 are slidably installed on the bottom of the two baffle plates 303; the output ends of the two driving cylinders 308 are respectively connected to the two side baffles 307, and the two driving cylinders 308 are fixedly installed on both sides of the inside of the processing channel 102.

[0040] Furthermore, the connecting bracket 401 is fixedly installed in the processing channel 102; the driving bracket 402 is slidingly connected to the connecting bracket 401 and fixedly installed on one side of the coating rack 302; the adjusting screw 403 is threadedly connected to the driving bracket 402 and rotatably installed on the connecting bracket 401; the output shaft of the adjusting motor 404 is connected to the adjusting screw 403, and the adjusting motor 404 is fixedly installed on one side of the connecting bracket 401.

[0041] When the present embodiment is in use, the glue discharging device 301 is arranged on the back side of the paint rack 302, and the discharging port of the paint rack 302 is slidably provided with two baffle plates 303, and the two baffle plates 303 are provided with corresponding abutment extension platforms, so that when the width of the discharging port of the paint rack 302 is adjusted by sliding the two baffle plates 303, the adhesive inside the paint rack 302 can be shielded by the abutment extension platforms provided by the baffle plates 303, and the back side of the paint rack 302 is also provided with a corresponding heating plate, through which The heating plate can ensure the normal flow and use of the internal adhesive. The shielding slide plate 304 is also provided on the paint rack 302. The shielding slide plate 304 provided on the paint rack 302 has the same effect as the sliding block frame 201 provided on the spray rack 104, and both are used to adjust the size of the discharge gap. The shielding slide plate 304 is driven by the driving screw 305 and the driving motor 306, so that the user can adjust the spraying gap size of the paint rack 302 by driving the shielding slide plate 304. The side baffles 307 are slidably mounted at the bottom of the baffle plates 303 arranged on both sides of the paint rack 302. The two side baffles 307 are driven by two driving cylinders 308 respectively. The driving cylinders 308 are fixedly arranged on the inner wall of the processing channel 102. When the driving cylinders 308 drive the side baffles 307 to slide, the side baffles 307 can drive the baffle plates 303 on both sides of the paint rack 302 to slide accordingly. 307 mainly clamps and shields the two sides of the base layer. The two side baffles 307 can prevent the wear-resistant particles coated on the base layer from falling off when the base layer moves. Moreover, driven by the two side baffles 307, the baffle plate 303 set on the paint rack 302 can also keep the width consistent with the base layer that actually needs to be sprayed with adhesive, so that the wear-resistant particles coated on the base layer can be more effectively and stably bonded when the adhesive is sprayed. The driving bracket 402 is fixed on the back side of the paint rack 302, and the driving bracket 402 keeps sliding with the connecting bracket 401 fixedly installed in the processing channel 102.

At the same time, since the material baffle plate 303 on the paint rack 302 can slide in the corresponding direction on the side baffle plate 307, the material baffle plate 303 will not interfere with the corresponding movement of the paint rack 302.

[0042] Preferably, the processing assembly provided by the present invention further includes a supporting base 501 , a supporting bracket 502 , a placing frame 503 , a driving roller 504 , a tensioning spring 505 and a screw lifting mechanism 506 .
