Description

Technical Field

[0001] The utility model belongs to a cottonseed fuzzing machine, in particular to a cylindrical propelling barbed cottonseed fuzzing machine. Background Art

[0002] At present, in traditional cottonseed fuzzing production, traditional saw-tooth cottonseed fuzzing machines are all adopted. Taking a set of six 160-type machines as an example in the usual process: one for the first pass, three for the second pass, two for the third pass, the cottonseed processing capacity is 4 tons per hour. For the six fuzzing machines plus two second-pass elevators and a set of double-spiked roller fuzz cleaners, the total power is 194 KW / h. The saw-tooth fuzzing machine process has the following problems: First, low output; second, high power consumption; third, high seed-breaking rate; fourth, extremely prone to fire; fifth, the saw blades swing and rub against the ribs, seriously damaging the saw blades and ribs; sixth, after a high seed-breaking rate, the cotton fuzz contains a high amount of impurities and must be cleaned. During the fuzz cleaning process, the fuzz fibers are seriously damaged, and the downgraded ultra-short fibers are sucked by the wind into the dust chamber, resulting in a loss of about 10% of the fuzz output; seventh, high noise and a poor working environment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cylindrical propelling barbed cottonseed fuzzing machine, which has a reasonable structure, can prevent the first-pass fuzz from jamming the ribs and the saw blades from swinging and rubbing against the ribs, thereby preventing fire, stabilize the length and quality of the short fuzz, improve the grade and output of the cotton fuzz, simplify the process flow, save electricity, and improve work efficiency.

[0004] The purpose of the utility model is realized as follows: A cylindrical propelling barbed cottonseed fuzzing machine, at both ends of the roller shaft in the machine shell are respectively connected with a roller having a fuzz outlet and a ventilation port through spoke rods. Axial fuzzing racks are evenly arranged on the inner wall of the roller. Both ends of the roller shaft are respectively inclined and installed on the frame through bearing seats. At both ends of the frame below the roller, two sets of symmetrically arranged supporting wheels are installed through the provided supporting wheel frames. The supporting wheels are matched with the guide rails on the outer cylinder of the roller. A gear ring is arranged on the outer cylinder in the middle of the roller. The driving gear driven by a first motor installed on the frame through a speed reducer is meshed with the gear ring. A second motor installed on the frame drives the roller shaft to rotate through chain drive. Fuzzing scraper assemblies are evenly installed on the roller shaft. Wire brushes arranged at the outer ends of the scrapers are matched with the fuzzing racks. A fuzz suction port is arranged on the top surface of the machine shell. The feed port of a screw conveyor arranged below the roller is connected with the discharge port of the roller.

[0005] The utility model fixes the main frame on the lower inclined frame. The outer cylinder of the main machine is supported by four groups of supporting wheels in the middle and lower part of the main frame to hold the cylinder. The concentricity between the cylinder and the roller shaft is ensured by three groups of centering assemblies and the center plate. Both ends of the roller shaft are supported by bearing seats, and the bearing seats are fastened on the frame. The roundness of the cylinder is ensured by five flange rings. A gear ring is installed around the middle flange ring, and a gear is engaged directly below the gear ring. The cylinder is driven by a motor through a speed reducer to rotate. The main machine can be inclined or horizontal. The inclination of the main machine is determined according to the demand of cotton seeds and the purity of cotton seed ginning. The inclination does not exceed 9 degrees. Cotton seeds enter the cylinder evenly through the conical opening of the feed hopper. The axial lint-removing racks on the inner walls of the two layers in the cylinder and the scraper racks on each scraper of the lint-removing scraper assembly fixed on the roller shaft rotate and advance to form frictional lint-removing work. The cylinder rotates forward and backward by 118 degrees, so that the axial lint-removing racks on the inner walls of the two layers of the cylinder will not be blocked by cotton seeds and debris, thus effectively rubbing and removing lint from the cotton seeds. Ventilation holes with relative density are longitudinally arranged within 66° directly opposite the lint suction port on the inner and outer layers of the cylinder. Air volume is supplemented from these ventilation holes and both ends of the cylinder to suck away the lint, so that the lint and impurities are effectively separated automatically and the lint is free of impurities. There are 74 sets of lint-removing scraper assemblies operating throughout the lint-removing machine to gradually push the ginned cotton seeds out of the machine.

[0006] Four groups of supporting wheels are installed below the middle of the frame and are joined with flange rings. The flange is joined with the outer cylinder to strengthen the roundness. An inner two-layer structure is installed on the inner wall of the outer cylinder, and axial lint-removing racks are installed on the inner wall. A gear ring is fixed on the outer periphery of the flange, and the gears are engaged with each other. The cylinder is driven by a motor through a speed reducer to rotate forward and backward by 118°. The motor drives the rotation of the roller shaft through a chain and sprockets. The supporting center plate and supports ensure the concentricity between the roller shaft and the circle. A rod seat is welded on the hoop. The whole machine has 222 sets of scraper racks on the scrapers, which are the most effective working points on the inner wall of the cylinder. A wire brush is installed at the top of the scraper, and the tip of the wire brush inserts 3 mm deep into the tip of the lint-removing rack to increase the lint-removing effect. The inclination of the scraper and the lint-removing rack is about 16° to push the cotton seeds forward. The lint-removing process is carried out in a working process with a total length of 8000 mm. Ventilation holes with a diameter of φ4 mm and relative density are arranged at 66° directly opposite the lint suction port. The symmetrical ventilation holes supplement the air volume to facilitate lint suction, and there are no holes at both ends, each leaving 1 meter. Beneficial effects

[0007] I. Save direct investment and equipment price difference. The price of a cylinder push-type D2m-L8m barbed cotton seed lint-removing machine is 450,000 yuan. It is equivalent to a set of six traditional sawtooth type 144 or 160 models, with 130,000 yuan per unit, totaling 780,000 yuan.
