DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the utility model provides a raw material impurity removing device for cotton roll production, comprising two groups of vertically oppositely distributed brackets 1, a mounting frame 5 is arranged under each group of brackets 1, and two vertically oppositely distributed springs 6 are installed between the mounting frame 5 and the bracket 1. Specifically, when in use, the positions of the two mounting frames 5 are fixed; a horizontally distributed screening drum 2 is rotatably connected between the tops of the two groups of brackets 1, and the screening drum 2 is a cylindrical structure with closed two ends. One end of the screening drum 2 is drivingly connected to a stepper motor 8 installed on the bracket 1, and the stepper motor 8 has its own power supply and start-stop switch. When in use, the stepper motor 8 can drive the screening drum 2 to rotate, and the angle at which the stepper motor 8 can drive the screening drum 2 to rotate each time can be set according to usage requirements.

[0022] A vibration motor 9 is installed on the outer wall of the screening drum 2. The vibration motor 9 has its own power supply and start-stop switch, and the power supply and start-stop switch of the vibration motor 9 are installed on the screening drum 2; and the screening drum 2 is also installed with a plurality of iron removal devices 4 that are equidistantly distributed along the circumference of the screening drum 2. The iron removal devices 4 include a frame structure 41 that is located outside the screening drum 2 and is fixedly connected to the screening drum 2. The frame structure 41 is arranged at an opening on one side away from the screening drum 2, and a sealing cover 42 that can be opened and closed is hinged at the opening position of the frame structure 41. The opening direction of each sealing cover 42 is toward the outside of the frame structure 41, and the other end of the hinged end of each sealing cover 42 is detachably connected to the frame structure 41, and each sealing cover 42 is detachably connected to the frame structure 41. A plurality of first electromagnets 43 distributed in a rectangular array are also embedded on one side of the sealing cover 42 close to the screening drum 2. The first electromagnets 43 are magnetic when powered on and lose their magnetism when powered off. Specifically, the plurality of first electromagnets 43 on each sealing cover 42 share a set of power supplies and start-stop switches, and the power supplies and the start-stop switches are both mounted on the outer surface of the sealing cover 42. When in use, the screening drum 2 can be first driven to rotate by the stepper motor 8 until one of the iron removal devices 4 is located at the top of the screening drum 2. Then, after the sealing cover 42 is opened, cotton can be added into the screening drum 2 by the feeding mechanism in the prior art or manually. After the feeding is completed, the sealing cover 42 is closed.

[0023] After the cotton is added into the screening drum 2, the first electromagnet 43 can be energized. Since the plurality of iron removal devices 4 are equidistantly distributed along the circumference of the screening drum 2, the broken iron blocks mixed in the cotton can be adsorbed in all directions. At the same time, the vibration motor 9 can be started, and the screening drum 2 can be driven by the stepping motor 8 to rotate. In this way, the iron removal device 4 can be rotated to the bottom position of the screening drum 2 in turn, and then stopped for a period of time. At this time, under the action of the vibration motor 9, the first electromagnet 43 can be conveniently used to adsorb the broken iron blocks at various positions in the cotton, thereby improving the removal effect of the broken iron blocks mixed in the cotton compared with the prior art.

[0024] When the cotton is cleaned, before the cotton in the screening drum 2 is discharged, the screening drum 2 can be driven to rotate by the stepper motor 8, so that the iron removal device 4 can be rotated to the top position of the screening drum 2 in turn, and then stop for a period of time, and open the sealing cover 42, and make the sealing cover 42 horizontally distributed. At this time, after the first electromagnet 43 is powered off, the broken iron blocks adsorbed on the first electromagnet 43 can be manually cleaned, and the sealing cover 42 can be closed after the cleaning is completed; and when the cotton in the screening drum 2 is discharged, one group of the iron removal devices 4 is first rotated to the bottom position of the screening drum 2, and then a material transport box with an open top surface can be placed under the other end of the hinged end of the sealing cover 42, so that after opening the sealing cover 42, when the sealing cover 42 falls on the opening position on the material transport box, the sealing cover 42 is tilted to facilitate the cotton to fall into the material transport box.

[0025] Since cotton contains impurities such as broken soil and other granular impurities, Figure 1 and Figure 2 As shown, a slag outlet is provided on the screening cylinder 2 between every two adjacent iron removal devices 4, and a screen 10 is installed in each slag outlet. A slag collecting box 7 located below the screening cylinder 2 and with an open top surface is detachably connected between the bottoms of the two groups of brackets 1, and the slag collecting box 7 can be used to contain particulate impurities; specifically, when in use, the screening cylinder 2 can be driven to rotate by the stepper motor 8, so that the screen 10 can be rotated to the bottom position of the screening cylinder 2 in turn, and then stopped for a period of time. At this time, under the action of the vibration motor 9, the particulate impurities mixed in the cotton can be removed by the screen 10; in addition, the situation in the screening cylinder 2 can be observed through the slag outlet; and when the cotton in the screening cylinder 2 is discharged later, the slag collecting box 7 needs to be removed.

[0026] The specific method of detaching the slag collecting box 7 is as follows: Figure 1 As shown, two horizontally oppositely arranged support rods 11 are fixedly connected to the inner side of each group of brackets 1, and a vertically distributed baffle 12 is fixedly connected between the two support rods 11. The slag collecting box 7 is located on the support rods 11 and between the two baffles 12. Specifically, when in use, the slag collecting box 7 is placed on the support rods 11, and the two sides of the slag collecting box 7 are slidably connected to the baffles 12, so that the slag collecting box 7 can be easily disassembled and assembled.

[0027] In order to facilitate the discharge of the cotton in the screening cylinder 2, Figure 1 As shown, a discharging device 3 is installed on the screening drum 2, and the discharging device 3 includes a rotating shaft 31 located in the screening drum 2 and coaxially arranged with the screening drum 2. Both ends of the rotating shaft 31 are rotatably connected to the screening drum 2, and one end of the rotating shaft 31 passes through the screening drum 2 and is drivingly connected to a driving motor 32 installed on the screening drum 2. The driving motor 32 has its own power supply and a start-stop switch, and the power supply and the start-stop switch of the driving motor 32 are installed on the screening drum 2; specifically, a transmission box 34 is installed at the end surface of the screening drum 2, one end of the rotating shaft 31 passes through the screening drum 2 and is located in the transmission box 34, and the driving motor 32 is installed in the transmission box 34. The output shaft of the driving motor 32 is connected to the rotating shaft 31 through a chain transmission mechanism in the transmission box 34; the rotating shaft 31 is also fixedly connected to a plurality of discharge rods 33 equidistantly distributed along the length direction of the rotating shaft 31, and the discharge rods 33 are all parallel to the radial direction of the rotating shaft 31. Specifically, when discharging the cotton in the screening drum 2, the driving motor 32 can drive the rotating shaft 31 to rotate slowly, and the rotating shaft 31 can drive the discharge rods 33 to rotate during the rotation process, so that the cotton in the screening drum 2 can be rotated to the bottom position of the screening drum 2 for easy discharge. At this time, the discharge can also be assisted manually to avoid blockage.

[0028] The specific method of detachably connecting the sealing cover 42 and the frame structure 41 is as follows: Figure 1 and Figure 4 As shown, the other end of the hinged end of each sealing cover 42 is inlaid with a plurality of second electromagnets, which are magnetic when energized and lose their magnetism when powered off; a supporting rod 44 for supporting the sealing cover 42 is fixedly connected to the middle position of the frame structure 41, and a metal plate that can be adsorbed by the second electromagnet is installed on the inner wall of the frame structure 41, and the second electromagnet and the metal plate are not shown in the figure. Specifically, a plurality of second electromagnets share a set of power supply and start-stop switches, and the power supply and the start-stop switch are installed on the outer surface of the sealing cover 42. When in use, after the sealing cover 42 is closed, the supporting rod 44 can support the sealing cover 42, and then, after the second electromagnet is energized, the second electromagnet cooperates with the metal plate to fix the sealing cover 42; and after the second electromagnet is powered off, the sealing cover 42 can be opened, so that when the cotton in the screening cylinder 2 is discharged, the sealing cover 42 can be automatically opened under the action of its own gravity.

[0029] Further, such as Figures 1 to 4 As shown, each sealing cover 42 is provided with a handle 45 on one side away from the screening drum 2 . Specifically, when in use, the handle 45 can facilitate opening and closing of the sealing cover 42 .
