[0024] Such as Figures 1 to 5As shown in the figure, a screen mechanism for a cotton carding machine in spinning includes a carding machine 1. Two square rods 2 are fixedly installed at the output end of the carding machine 1. A cotton hopper 3 is fixedly installed between the two square rods 2. Two mounting frames 4 are arranged inside the cotton hopper 3. A screen 5 is fixedly installed inside each mounting frame 4. A driving mechanism 6 for driving the two mounting frames 4 to move is arranged on the cotton hopper 3. Two drainage plates 7 are fixedly installed inside the cotton hopper 3. Vibration mechanisms 8 for pushing the screen 5 are arranged on the left and right side walls inside the cotton hopper 3. Discharge ports 9 are formed on the left and right side walls of the cotton hopper 3 corresponding to the lowest ends of the drainage plates 7. Removable slag collection boxes 10 are arranged at the positions corresponding to the discharge ports 9 on the left and right sides of the cotton hopper 3. It should be noted that when feeding the cotton bale, first place the cotton bale into the cotton hopper 3. At this time, the two mounting frames 4 are in contact with each other. The two mounting frames 4 and the two screens 5 can jointly carry the cotton bale. To remove the impurities in the cotton bale, immediately start the two groups of vibration mechanisms 8 at this time. Use the two groups of vibration mechanisms 8 to continuously impact the two screens 5, so that the cotton bale located above the screen 5 keeps shaking. The impurities mixed in the cotton bale will pass through the screen 5 and fall onto the surfaces of the two drainage plates 7, and then roll down to the lower part from the surfaces of the two drainage plates 7, so that the impurities can pass through the two discharge ports 9 and fall into the two slag collection boxes 10 respectively. After the impurities in the cotton bale located above the screen 5 are removed, then control the driving mechanism 6 to separate the two mounting frames 4. The cotton bale located above the screen 5 gradually falls from the gap between the two mounting frames 4, and finally the falling cotton bale enters the carding machine 1 from the output end of the cotton hopper 3. Use the carding machine 1 to process the cotton bale.

The two rack rods 608 are respectively detachably connected to the two mounting frames 4. It should be noted that by starting the hydraulic rod 1 602, the racks 603 on both sides can be moved up and down, thereby causing the two gears 1 604 to rotate reciprocatingly. The reciprocating rotation of each gear 1 604 drives the adjacent gear 2 605 to rotate reciprocatingly, thereby causing the two rack rods 608 to move away from each other. Each rack rod 608 drives the limit block 607 connected to it to slide in the corresponding limit slot 606, thereby causing the two mounting frames 4 to move away from or approach each other.

[0026] Such as Figures 1 to 4 As shown, the driving mechanism 6 also includes two mounting slots 609, and a mounting slot 609 is provided on the side of each rack rod 608 away from the adjacent limit block 607, and a plurality of threaded holes 610 are provided on the side wall of each rack rod 608, each threaded hole 610 is connected to the inside of the mounting slot 609, and a bolt 611 is threadedly connected to the inside of each threaded hole 610, and a connecting rod 612 is movably installed inside each mounting slot 609, and a threaded groove 613 is provided on the side wall of each connecting rod 612 corresponding to each adjacent threaded hole 610, and the tail end of each bolt 611 is threadedly connected to the inside of the adjacent threaded groove 613.

It should be noted that when the hydraulic rod 2 801 is started, it can drive the push plate 802 to move back and forth in a straight line, and each push plate 802 continuously impacts the screen 5 when it moves back and forth.

[0028] As shown Figure 3 , Figure 5 shown, convex grooves 11 are respectively formed on the outer wall surfaces on the left and right sides of the cotton hopper 3. A convex rod 12 is movably installed inside each convex groove 11, and the convex rods 12 are fixedly connected to the adjacent slag collection boxes 10. It should be noted that by pulling out the convex groove 11 from the inside of the convex rod 12, the slag collection box 10 can be disassembled to facilitate dumping of the impurities inside the slag collection box 10.

The two mounting frames 4 and the two screens 5 can jointly carry the cotton roll. To remove the impurities in the cotton roll, immediately start the two groups of vibration mechanisms 8 at this time. The two groups of vibration mechanisms 8 continuously impact the two screens 5, so that the cotton roll located above the screens 5 continuously shakes. The impurities doped in the cotton roll will pass through the screens 5 and fall onto the surfaces of the two drainage plates 7, and then roll down to the lower part from the surfaces of the two drainage plates 7, so that the impurities can pass through the two slag outlets 9 and roll into the two slag collection boxes 10 respectively. After the impurities on the cotton roll above the screens 5 are removed, then control the driving mechanism 6 to separate the two mounting frames 4. The cotton roll above the screens 5 gradually falls from the gap between the two mounting frames 4, and finally the falling cotton roll enters the carding machine 1 from the output end of the cotton hopper 3, and the carding machine 1 is used to process the cotton roll.
