Description

Technical Field

[0001] The present invention relates to the technical field of cotton fibers, and in particular to a cotton fiber granulating device and a use method thereof. Background Art

[0002] Fiber refers to a substance composed of continuous or discontinuous filaments. In plants and animals, fibers play a vital role in maintaining tissue. Fiber has a wide range of uses, including being woven into thread, yarn, and rope, and forming fiber sheets for papermaking or felting. Fiber is also commonly used to manufacture other materials and to form composite materials with other materials. Cotton fiber generally refers to cotton, and its production typically requires granulation.

[0003] However, the existing cotton fiber granulation is prone to uneven particle size, which affects the granulation quality. The particles that do not meet the requirements need to be screened and removed. At the same time, there are loose fibers on the surface of the particles after granulation that are not effectively embedded in the particle structure. These loose fibers form surface residues on the outside of the particles, which will further reduce the granulation quality. Moreover, when the particles are screened, these loose fibers are easy to clog the sieve holes, affecting the particle screening efficiency and screening quality. Summary of the Invention

[0016] 2. The cotton fiber granulation device and its use method ensure that the particle size is controlled within the range of 0.5-3mm through the arc design of the granulation plate and the rotary cutting of the scraper, thereby ensuring the quality of cotton fiber granulation production.

[0017] 3. The cotton fiber granulating device and the method of use thereof adopt a "mechanical trigger + elastic reset" dual-mode operation through the cleaning part: when the first sleeve moves toward the cotton fiber outlet, the pull rope no longer pulls the arc-shaped cleaning hook, so that it extends from the arc-shaped groove of the cleaning rod, and the hook teeth are embedded in the edge of the sieve hole to hook the cotton fibers on the sieve plate. When moving toward the particle outlet, the pull rope applies tension to the arc-shaped cleaning hook, and the arc-shaped cleaning hook shrinks in the cleaning rod.

Collection containers can be provided at the particle outlet 101 and the cotton fiber outlet 102 for collection, such as a cloth bag or a box. The fan 4 is fixed on the screening box 1 and is on the same side as the particle outlet 101. The exhaust end of the fan 4 faces the cotton fiber outlet 102, and the auxiliary screening mechanism 5 is arranged in the screening box 1. The screening box 1 serves as the main container, with a granulation mechanism 2 integrated on the top, and a screening plate 3 fixed horizontally inside to divide the cavity into two parts, the upper and lower parts. The screening plate 3 is used to screen qualified particles larger than the screening hole.

[0024] like Figure 4 and Figure 6As shown, as a preferred embodiment, on the basis of the above-mentioned method, the granulation mechanism 2 further includes a granulation cylinder 201 fixedly connected to the screening box 1 and having an opening at one end, a feed port 202 arranged at the top of the granulation cylinder 201, a first motor 203 fixedly connected to one end of the granulation cylinder 201, a drive shaft 204 connected to the output shaft of the first motor 203 and rotatably connected to the granulation cylinder 201, a spiral conveying blade 205 arranged on the drive shaft 204, and a feed port 202 arranged at the end opening of the granulation cylinder 201. The granulation plate 206 has a number of evenly distributed granulation holes 2061; the first motor 203 drives the spiral conveying blade 205 to rotate at 280-320 rpm to convey the cotton fiber from the feed port 202 to the granulation plate 206. The diameter of the granulation hole 2061 of the granulation plate 206 can be designed to be 1.5-3 mm. The spiral conveying blade 205 can be designed according to the compression ratio gradient. The pitch of the inlet section is 120 mm to pre-press the loose material, and the pitch of the outlet section is 80 mm for high-pressure molding.

During this period, the fan 4 blows the cotton fiber cloth, and the cotton fiber residue moves toward the cotton fiber outlet 102. The screening plate 3 screens the particles that do not meet the particle size requirements, and the particles that meet the requirements remain on the screening plate 3.

[0026] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the auxiliary screening mechanism 5 further includes a second motor 501 fixed on the screening box 1 and on the same side as the particle outlet 101, a first reciprocating screw rod 502 connected to the output shaft of the second motor 501 and rotatably connected to the screening box 1, a first sleeve 503 threadedly connected to the first reciprocating screw rod 502, and an auxiliary screening portion 504 provided on the first sleeve 503; Furthermore, the auxiliary screening part 504 includes a movable seat 5041 movably arranged on the top of the first sleeve 503, a first elastic telescopic rod 5042 arranged between the movable seat 5041 and the first sleeve 503, a rotating shaft 5043 rotatably connected to the movable seat 5041, a material-diverting plate 5044 fixed on the rotating shaft 5043, a movable gear 5045 arranged at the end of the rotating shaft 5043, and a gear rack 5046 fixed on the inner wall of the screening box 1 and meshing with the movable gear 5045. The gear rack 5046 is composed of a spur gear rack and The arc-shaped tooth racks are arranged at both ends of the straight tooth rack, and the end of the material stripping plate 5044 away from the rotating shaft 5043 is movably against the screening plate 3. The material stripping plate 5044 is composed of two elastic and retractable plate bodies, so that the material stripping plate 5044 can abut against the top of the screening plate 3 even if it moves up with the rotating shaft 5043. Second elastic retractable rods 7 are fixed on both sides of the inner wall of the screening box 1. A limit block 701 is provided at one end of each second elastic retractable rod 7 away from the screening box 1. The limit block 701 is provided with an extrusion inclined surface that is movably against the rotating shaft 5043; When the auxiliary screening mechanism 5 is working, the second motor 501 drives the first reciprocating screw 502 to rotate in the screening box 1, and the first sleeve 503 moves axially along the first reciprocating screw 502. When the first sleeve 503 moves, it drives the rotating shaft 5043 to move, and the movable gear 5045 on the rotating shaft 5043 is meshed with the teeth on the gear rack 5046 for transmission, so that the rotating shaft 5043 drives the material plate 5044 to intermittently move the particles that meet the requirements on the screening plate 3 to the particle outlet 101. During this period, the particles being moved shake, which speeds up their screening efficiency and makes it easier for the cotton fibers remaining on the particles to be blown by the wind generated by the fan 4; when the first sleeve 503 is about to When the first sleeve 503 moves to the end of the first reciprocating screw rod 502, the rotating shaft 5043 abuts against the extruded inclined surface of the limit block 701, and the limit block 701 avoids the movement of the rotating shaft 5043. When the first sleeve 503 moves to the end of the first reciprocating screw rod 502, it starts to move back. The limit block 701 limits the downward movement or upward movement of the rotating shaft 5043, so that the rotating shaft 5043 can only move from the original position below the gear frame 5046 to the upper movement of the gear frame 5046 or from the original position above the gear frame 5046 to the lower movement of the gear frame 5046, so that the rotating shaft 5043 continues to drive the diverter plate 5044 to divert the particles on the screening plate 3. It should be noted that in order to avoid the floating cotton fiber residue in the screening box 1 affecting the transmission performance between the various mechanisms, each structure can use self-lubricating materials or lubricating coatings or stainless steel materials to reduce limiting attachment and electrostatic adsorption. At the same time, the air gap nozzle and rotating brush in the existing technology can be set at the movable gear 5045 or the sleeve. This is the existing technology and will not be elaborated here.

When the first sleeve 503 moves from the cotton fiber outlet 102 to the particle outlet 101, the arc-shaped cleaning hook 112 is in the cleaning rod 111 and does not abut against the screening plate 3. When the first sleeve 503 moves from the particle outlet 101 to the cotton fiber outlet 102 along the first reciprocating screw rod 502, the upward movable seat 5041 drives the fixed rod 114 to move upward, and no longer applies tension to the pull rope 113. The arc-shaped cleaning hook 112 is reset and moves out of the cleaning rod 111 under the action of the arc spring and abuts against the screening plate 3, removing the cotton fibers remaining on the screening plate 3. When the first sleeve 503 moves to the other end of the first reciprocating screw rod 502, the rotating shaft 5043 abuts against the extrusion slope of the limit block 701 again.
