[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention is configured by cooperating with each other through a crushing component and a separation component. When separating and recycling textile fiber waste, the first rotating shaft is first driven to rotate by a motor, and the rotation of the first rotating shaft drives one of the crushing rollers to rotate, and the rotation of the crushing roller drives the first gear to rotate. The two crushing rollers are driven by the first gear to rotate relative to each other at the same time, and then the waste is put into the feed port to crush the textile fiber waste by the crushing roller. At the same time, the fan is started to make the recovery box negatively pressurized, and the lighter waste in the crushed waste is sucked away, and finally blocked by the filter plate and falls downward to the inside of the second collection box for collection. The waste is collected separately by the first collection box and the second collection box, thereby improving the separation efficiency of the textile fiber waste.

[0025] 2. The present invention arranges a throwing assembly. When textile fiber waste is crushed, the first rotating shaft rotates to drive the second rotating shaft to rotate through the transmission of the first pulley group. The rotation of the second rotating shaft drives the rotation of the throwing roller. The rotation of the throwing roller drives the rotation of the throwing plate. The throwing plate contacts the waste on the top of the guide plate during the rotation and throws it into the air, which helps the fan to suck away the waste with lighter density for separation, thereby improving the separation efficiency of the waste.

[0026] 3. The present invention arranges the scraper assembly.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, in an embodiment of the present invention, a textile fiber waste separation and recovery device comprises a recovery box 1, a feed port 2 is fixedly installed at the top of the recovery box 1, a crushing component is arranged below the feed port 2, and a separation component is arranged inside the recovery box 1;

[0038] The crushing assembly includes a crushing roller 3 arranged below the feed port 2. Two crushing rollers 3 are provided. Both crushing rollers 3 are rotatably connected to the recovery box 1 through a first rotating shaft 4. A motor 5 is installed at one end of one of the first rotating shafts 4. First gears 6 are fixedly installed on the outer walls of the two crushing rollers 3. The two first gears 6 are meshed and connected.

[0039] The separation component includes a fan 14 arranged inside the recycling box 1, a filter plate 13 is arranged on one side of the fan 14, the filter plate 13 is fixedly installed inside the recycling box 1, a material guide plate 12 is fixedly installed inside the recycling box 1, a throwing component is arranged above the material guide plate 12, a first collecting box 16 is arranged below the material guide plate 12, the first collecting box 16 is slidably installed inside the recycling box 1, a second collecting box 17 is slidably connected inside the recycling box 1, the second collecting box 17 is arranged below the filter plate 13, and a scraping component is arranged on one side of the filter plate 13.

[0040] When separating and recycling textile fiber waste, firstly, the first rotating shaft 4 is driven to rotate by the motor 5, and the rotation of the first rotating shaft 4 drives one of the crushing rollers 3 to rotate, and the rotation of the crushing roller 3 drives the first gear 6 to rotate, and the two crushing rollers 3 are driven by the first gear 6 to rotate relative to each other at the same time, and then the waste is put into the feed port 2, so that the textile fiber waste is crushed by the crushing roller 3;

[0041] The crushed waste falls on the top of the guide plate 12, and the mechanical vibration of the device itself drives the waste to move to one side, and finally moves to the inside of the first collection box 16 for collection;

[0042] At the same time, the fan 14 is started to create a negative pressure in the recovery box 1, which sucks away the lighter waste in the crushed waste, and finally stops it from falling down to the inside of the second collecting box 17 for collection. The waste is collected separately by the first collecting box 16 and the second collecting box 17, thereby improving the separation efficiency of the textile fiber waste.

[0043] like Figures 1 to 8 As shown, the guide plate 12 is arranged tilted.

[0044] It is used to guide the crushed waste materials to facilitate the movement and collection of the waste materials.

[0045] like Figure 2 and Figure 5 As shown, the throwing assembly includes a throwing roller 7 arranged above the guide plate 12, and the outer wall of the throwing roller 7 is evenly distributed with throwing plates 8 in a ring array, and both ends of the throwing roller 7 are fixedly installed with a second rotating shaft 9, and the second rotating shaft 9 is rotatably installed inside the recovery box 1, and one of the second rotating shafts 9 is transmission-connected to the first rotating shaft 4 through a first pulley set 10.

[0046] When textile fiber waste is crushed, the first rotating shaft 4 rotates through the transmission of the first pulley group 10 to drive the second rotating shaft 9 to rotate, and the rotation of the second rotating shaft 9 drives the rotation of the throwing roller 7, and the rotation of the throwing roller 7 drives the rotation of the throwing plate 8, so that the throwing plate 8 contacts the waste on the top of the guide plate 12 during the rotation and throws it into the air, which helps the fan 14 to suck away the lighter waste for separation, thereby improving the separation efficiency of the waste.

[0047] like Figure 2 and Figure 5 As shown, a grid baffle 15 is provided on one side of the throwing roller 7 , and the grid baffle 15 is provided between the first collecting box 16 and the second collecting box 17 .

[0048] The grid baffle 15 blocks and buffers the scattered waste materials, preventing the throwing roller 7 from throwing the waste materials with higher density into the second collecting box 17 during the rotation of the throwing roller, thereby ensuring the separation effect of the waste materials.

[0049] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the scraper assembly includes a scraper 18 arranged on one side of the filter plate 13, and movable plates 19 are installed at both ends of the scraper 18. The internal thread of one of the movable plates 19 is connected to a reciprocating screw 20, and the bottom end of the reciprocating screw 20 is fixedly installed with a first bevel gear 21, and the bottom end of the first bevel gear 21 is meshingly connected with a second bevel gear 22. A third rotating shaft 23 is fixedly installed on one side of the second bevel gear 22, and the third rotating shaft 23 is transmission-connected to the second rotating shaft 9 through a second pulley set 11.

[0050] In the process of the throwing roller 7 rotating and throwing the material, the second rotating shaft 9 drives the third rotating shaft 23 to rotate through the second pulley set 11, and the rotation of the third rotating shaft 23 drives the rotation of the second bevel gear 22, and the rotation of the second bevel gear 22 drives the rotation of the first bevel gear 21, and the rotation of the first bevel gear 21 drives the rotation of the reciprocating screw 20, and the rotation of the reciprocating screw 20 drives the movable plate 19 to move up and down, and the movement of the movable plate 19 drives the movement of the scraper 18, so that the scraper 18 moves to scrape off the waste on the side wall of the filter plate 13, preventing the fan 14 from always sticking to the side of the filter plate 13 due to the suction when sucking the waste with lighter density, which will not only affect the recovery effect of this part of the waste, but also block the through hole of the filter plate 13, affecting the subsequent separation effect, and scraping off the waste on the side of the filter plate 13 helps to improve the separation efficiency of the device for waste.

[0051] like Figure 2 and Figure 4 As shown, the side wall of the scraper plate 18 is slidably fitted with the filter plate 13 .

[0052] like Figure 6 to Figure 7 As shown, scraping teeth 28 are arranged inside the scraper 18, and the scraping teeth 28 are evenly distributed.

[0053] When the scraper 18 is moving, the scraper teeth 28 can be used to pick up waste materials in the through holes of the filter plate 13 to ensure the negative pressure separation effect of the device.

[0054] like Figure 8 As shown, the scraper tooth 28 is slidably installed inside the scraper plate 18 , and a spring 29 is provided on one side of the scraper tooth 28 .

[0055] Making the scraper teeth 28 elastic not only helps to discharge the waste inside the through hole of the filter plate 13, but also reduces the wear between the scraper teeth 28 and the filter plate 13, thereby increasing the service life.

[0056] like Figure 4 and Figure 6As shown, the scraper 18 is rotatably connected to the movable plate 19 via a fourth rotating shaft 25 , a second gear 26 is fixedly mounted on the outer wall of the fourth rotating shaft 25 , a rack plate 27 is meshedly connected to one side of the second gear 26 , and the rack plate 27 is fixedly mounted inside the recovery box 1 .

[0057] When the scraper 18 moves to the bottom of the filter plate 13, the second gear 26 meshes with the rack plate 27 and rotates. The rotation of the second gear 26 drives the rotation of the fourth rotating shaft 25. The rotation of the fourth rotating shaft 25 drives the rotation of the scraper 18, so that the scraper 18 flips over to prevent some waste from falling on the top of the scraper 18 and being difficult to collect due to the continuous negative pressure of the fan 14 when the scraper 18 moves. Rotating the scraper 18 helps to pour down the waste on the top of the scraper 18 for recycling.

[0059] S1: When separating and recycling textile fiber waste, firstly, the first rotating shaft 4 is driven to rotate by the motor 5, and the rotation of the first rotating shaft 4 drives one of the crushing rollers 3 to rotate, and the rotation of the crushing roller 3 drives the first gear 6 to rotate, and the two crushing rollers 3 are driven by the first gear 6 to rotate relative to each other at the same time, and then the waste is put into the feed port 2, and the textile fiber waste is crushed by the crushing roller 3;

[0060] S2: The crushed waste falls on the top of the guide plate 12, moves to one side of the first collecting box 16, and is finally collected inside the first collecting box 16;

[0061] S3: The rotation of the first rotating shaft 4 drives the second rotating shaft 9 to rotate through the first pulley group 10, the rotation of the second rotating shaft 9 drives the rotation of the throwing roller 7, and the rotation of the throwing roller 7 drives the rotation of the throwing plate 8, so that the throwing plate 8 contacts the waste on the top of the guide plate 12 during the rotation process and throws it into the air;

[0062] S4: At the same time, the fan 14 is started to create a negative pressure in the recovery box 1, so that the lighter waste in the crushed waste is sucked away, and finally blocked by the filter plate 13 and falls downward to the inside of the second collection box 17 for collection;

[0063] S5: The rotation of the second rotating shaft 9 drives the third rotating shaft 23 to rotate through the second pulley set 11, the rotation of the third rotating shaft 23 drives the rotation of the second bevel gear 22, the rotation of the second bevel gear 22 drives the rotation of the first bevel gear 21, the rotation of the first bevel gear 21 drives the rotation of the reciprocating screw 20, the rotation of the reciprocating screw 20 drives the movable plate 19 to move up and down, the movement of the movable plate 19 drives the movement of the scraper 18, so that the scraper 18 moves to scrape the waste on the side wall of the filter plate 13 and collect it in the second collecting box 17.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
