Abstract
Description
Technical Field
[0001] The utility model relates to the field of textile machinery, in particular to a textile impurity removal device, and in particular to a double-roller cotton opener. Background Art
[0002] In the pre-spinning process, the fine cotton opener is a device used to further finely open and remove impurities from the raw materials. The existing fine cotton opener is a single-roll fine cotton opener, which has an unsatisfactory impurity removal effect when processing machine-picked cotton with high impurity content.
[0003] In the existing flower cleaning process, the following two technical solutions are usually used. The first one is a double-series opening and loosening method represented by the applicant, such as Figure 1 As shown, two single-roll fine cotton openers are connected in series to open and remove impurities in two steps. This solution has the following disadvantages:
[0004] ① Large floor space: Since two single-roller fine cotton openers need to be placed, a certain distance must be left between the two devices to ensure that the doors of the two devices can be opened normally, so the floor space is relatively large.
[0005] ② High energy consumption: Both single-roller fine cotton openers need to use cotton inlet fans and cotton feed motors independently, which consumes a lot of energy. The total power of the two devices is about 24kw.
[0006] The second is the three-roller fine cotton opener solution represented by Trützschler and Zhengfangji, such as Figure 2 As shown,
[0007] This three-roller fine cotton opening machine equipment contains three horizontally placed φ250mm opening rollers, each of which is equipped with a set of combing plates and trash suction ports.
[0008] This three-roller fine cotton opener has the following disadvantages when not in use:
[0009] ① The distance between the opening roller and the carding plate is small and cannot be adjusted, only 1.5mm, resulting in a small cotton passage and low production capacity, with a maximum output of only 1000kg / h.
[0010] ② The diameter of the opening roller is too small, and each beater can be assigned fewer impurity removal points. The whole machine has only 4 impurity removal points, and the impurity removal effect is not ideal.
[0011] ③ The speeds of the two opening rollers at the back are 1.7 times that of their previous ones, resulting in the speed of the last opening roller reaching over 3000rpm. This places high requirements on the horizontality of the equipment and the dynamic balance of the opening rollers, resulting in high manufacturing costs for the equipment. Utility Model Content
[0012] In order to meet the high requirements of domestic and foreign customers for impurity removal efficiency when spinning high-impurity machine-picked cotton, the applicant has developed a double-roller fine cotton opener with high impurity removal.
[0013] The technical solution adopted by the utility model is as follows:
[0014] A double-roller fine cotton opening machine for efficient impurity removal comprises a condenser, a cotton storage box, a frame, star rollers, front and rear steel rollers, a first adjustable dust grid, a first opening roller, a first cotton suction bucket, a second adjustable dust grid, a second opening roller, a second cotton suction bucket, a cotton outlet and a cotton suction pipe, wherein the condenser is mounted on the upper part of the cotton storage box, the cotton storage box is mounted on the frame, the star rollers, front and rear steel rollers, the first adjustable dust grid, the first opening roller, the first cotton suction bucket, the second adjustable dust grid, the second opening roller and the second cotton suction bucket are all mounted on the inner side of the frame, and the cotton suction pipe is mounted on the outside of the frame On both sides, the cotton outlet is installed on the upper right side of the frame, the star roller is located between the cotton storage box and the front and rear steel rollers, the first opening roller is located below the front and rear steel rollers, the second opening roller is located on the right side of the first opening roller, the first adjustable dust grid is located at the lower left of the first opening roller, the second adjustable dust grid is located at the lower left of the second opening roller, the first cotton suction hopper is located below the first adjustable dust grid and the first opening roller, the second cotton suction hopper is located below the second adjustable dust grid and the second opening roller, and the outlets on both sides of the first cotton suction hopper and the second cotton suction hopper are respectively connected to the cotton suction pipes on both sides.
[0015] Furthermore, the first opening roller is a porcupine opening roller, and the second opening roller is a comb needle opening roller.
[0016] Furthermore, the first opening roller and the second opening roller have the same rotation direction.
[0017] Furthermore, the diameters of the first opening roller and the second opening roller are both 600 mm.
[0018] Furthermore, the spacing between the first opening roller and the second opening roller is adjusted. The first opening roller is fixed to the frame through a bearing seat, and its position remains fixed. The second opening roller is also fixed to the frame through a bearing seat, and its position can be adjusted by adjusting the adjustment mechanism composed of an adjustment support, an adjustment bolt and an adjustment nut located at both ends of the opening roller, thereby adjusting the spacing between the second opening roller and the first opening roller.
[0019] Furthermore, the first adjustable dust grid is fixed to the frame as a whole through a pin shaft and can rotate around the pin shaft. By adjusting the nut on the adjusting bolt, the rotation angle of the first adjustable dust grid is controlled to control the distance between the first adjustable dust grid and the first opening roller, thereby achieving the overall adjustable distance between the dust removal knife of the first adjustable dust grid and the first opening roller.
[0020] Furthermore, the angle of the adjustment plate is adjustable as a whole.
[0021] Furthermore, the overall adjustment of the angle of the adjustment plate can be achieved by adjusting the adjusting handle, and the angle of the adjusting plate on each dust removal knife of the first adjustable dust grid can be adjusted as a whole. For individual fine-tuning of the angle of the adjustment plate, loosen the first locking screw and the second locking screw, and rotate the adjusting seat to fine-tune the angle of the adjustment plate, and tighten the first locking screw and the second locking screw after adjustment; the spacing between the dust removal knife of the second adjustable dust grid and the second opening roller is adjustable as a whole, and the second adjustable dust grid is fixed to the frame as a whole through a pin shaft and rotates around the pin shaft, and the rotation angle of the second adjustable dust grid is controlled by adjusting the nut on the adjusting bolt to control the spacing between the second adjustable dust grid and the second opening roller, the angle of the adjustment plate is adjustable as a whole, and the angle of the adjusting plate on each dust removal knife of the second adjustable dust grid can be adjusted as a whole by adjusting the adjusting handle, and the angle of the adjusting plate can be fine-tuned individually at the same time, loosen the first locking screw and the second locking screw, and rotate the adjusting seat to fine-tune the angle of the adjustment plate, and tighten the first locking screw and the second locking screw after adjustment.
[0022] Furthermore, the first adjustable dust grid includes a dust removal knife, and the second adjustable dust grid includes 5 dust removal knives.
[0023] The working process of the double-roll fine cotton opener with high efficiency in removing impurities described in the utility model is as follows:
[0024] After the raw materials are initially loosened and impurities removed by the front equipment, they are sucked into the condenser by the cotton inlet fan of the condenser. Some dust and impurities are removed through the volute and dust cage, and fall into the cotton storage box from the bottom of the dust cage.
[0025] The raw material that falls into the cotton storage box passes through the star roller and the front and rear steel rollers and is fed into the beater room. One end of the raw material is held by the front and rear steel rollers, and the other end is hit at high speed by the first opening roller to be opened into smaller cotton tufts. The raw material is transferred in the beater room along the rotation direction of the first opening roller to between the first opening roller and the second opening roller. The raw material is torn in reverse by the two opening rollers between the first and second opening rollers to be further opened into smaller cotton tufts. The raw material continues to be transferred in the beater room along the rotation direction of the second opening roller and enters the next machine through the cotton outlet.
[0026] The raw materials are gripped by the front and rear steel rollers and are first hit at high altitude by the first opening roller to be loosened into smaller cotton tufts. During the transfer process in the beater room, the raw materials pass through the dust removal knife on the first adjustable dust grid at the lower left of the first opening roller. Some impurities fall into the first suction cotton drop hopper due to the combined effect of centrifugal force and the stripping of the dust removal knife. When the other raw materials are transferred between the first opening roller and the second opening roller, they are further loosened into smaller cotton tufts. The impurities previously inside the raw materials are exposed on the outer surface of the raw materials, pass through the dust removal knife on the second adjustable dust grid at the lower left of the second opening roller, and some of them are removed again and fall into the second suction cotton drop hopper.
[0027] The impurities dropped into the first cotton suction bucket and the second cotton suction bucket are discharged to the dust filtering device through the cotton suction pipes on both sides of the equipment.
[0028] Beneficial effects achieved by the utility model:
[0029] Compared with two single-roller fine cotton openers connected in series, the double-roller fine cotton opener uses one less set of condenser star rollers and front and rear steel rollers and other cotton feeding components, so the equipment's footprint is reduced by more than 60% and energy consumption is reduced by more than 16%.
[0030] Since the distance between the dust removal knife of the first adjustable dust grid and the first opening roller of the double-roller fine cotton opening machine described in the utility model is adjustable as a whole, the distance between the dust removal knife of the second adjustable dust grid and the second opening roller is also adjustable as a whole, the maximum output can reach 1500kg / h.
[0031] Since the double-roll fine cotton opening machine uses large-diameter opening rollers, more impurity removal points are set around the opening rollers. A total of fourteen dust removal knives are installed on the whole machine, which has a better impurity removal effect.
[0032] Since the two opening rollers of the double-roll fine cotton opener rotate in the same direction, the speed of the second opening roller is only 50rpm higher than that of the first opening roller, and the maximum speed is 750rpm. The dynamic balance requirements of the opening roller and the installation requirements of the equipment are much lower than those of the three-roll fine cotton opener, which is conducive to reducing the equipment manufacturing cost.
