Description

Technical Field

[0001] The invention relates to a dust remover, in particular to a flannel dust remover, and belongs to the technical field of mechanical design and manufacturing. Background Art

[0002] With the continuous development of the tobacco industry, tobacco companies have higher and higher requirements for the purity of raw tobacco, because the purity of raw tobacco directly affects the formula of cigarettes and the quality of finished products. Since the production and initial baking of raw tobacco are mostly completed in rural areas, it is inevitable that foreign objects will be mixed into the tobacco leaves, and in many links such as tobacco leaf sorting, bundling, hanging on poles, baking, moisture regeneration, storage, grading, tying, hemp belt packaging, purchasing, and transportation, it is also inevitable that hemp ropes, hemp silk, poultry feathers, hair, plastic silk, weeds and other foreign objects will be mixed in.

[0003] At present, tobacco production enterprises are basically equipped with impurity removal equipment such as photoelectric impurity removal and air separation impurity removal. These impurity removal methods can remove most impurities in tobacco leaves, but it is still difficult to effectively remove light and fine impurities such as plastic filaments, hemp ropes, insect eggs, threads, and hair mixed in tobacco leaves. For this reason, many tobacco enterprises have also installed equipment for removing filamentous and velvety impurities. The principle is to set up a row of steel wire rollers. When tobacco leaves pass through the steel wire rollers, the filamentous and velvety impurities in the steel wire rollers will be stuck in the steel wires of the steel wire rollers and separated from the tobacco leaves. However, this equipment has the following defects: (1) The steel wire is relatively hard and has a weak ability to capture impurities, resulting in low impurity removal efficiency; (2) It is impossible to clean up impurities in real time, and the impurities are stuck by the steel wire and may be brought back into the tobacco leaves by other tobacco leaves during operation; (3) Cleaning up impurities requires manually removing the steel wire rollers and then manually cleaning up the impurities on the steel wire rollers, which is difficult to clean up, time-consuming, and wastes labor resources. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0004] In order to solve the problems of poor impurity removal effect, low impurity removal efficiency, great cleaning difficulty, and waste of human resources in existing filamentous and velvety impurity removal equipment, the present invention provides a velvet impurity removal machine.

[0005] The present invention is completed by the following technical scheme: a flannel impurity remover, comprising a support frame arranged on a material conveyor, characterized in that the support frame is provided with an impurity removal flannel assembly and an impurity cleaning assembly matched with the impurity removal flannel assembly, wherein: The de-impurity flannel assembly comprises: a flannel support roller group and a driving assembly for driving the flannel support roller group to operate, the flannel support roller group comprises front and rear horizontal rollers arranged on the supporting frame, and front and rear tensioning rollers arranged below the front and rear horizontal rollers, and de-impurity flannel wound around the front and rear horizontal rollers and the front and rear tensioning rollers and arranged in a trapezoidal shape, and the lower horizontal fluff direction of the de-impurity flannel is made to be the same as the material conveying direction of the material conveyor, and the running speed of the de-impurity flannel is greater than the conveying speed of the material conveyor; so that when the driving assembly drives the flannel support roller group to rotate and then drives the de-impurity flannel to move, the fluff on the de-impurity flannel can hook and take away impurities in the material, which not only improves the de-impurity efficiency, but also does not cause damage to the material by the de-impurity flannel.

The cleaning drum is provided with at least one flexible scraper so as to regularly or periodically scrape the debris on the cleaning flannel into the collecting box below.

[0008] The shafts at both ends of the cleaning drum are respectively connected to the seat bearings on the support frame, and the shaft at one end extends to the outside of the seat bearing and is connected to the motor. The cleaning drum is driven to rotate by the motor, and then the scraper thereon scrapes the debris on the cleaning velvet cloth into the collection box below.

[0009] The collection box is configured as a drawer-type collection box, so that the sundries can be conveniently drawn out and dumped out at regular intervals.

[0010] Furthermore, the two ends of the roller shafts of the front and rear horizontal rollers of the support roller group are respectively matched with the belt seat bearings arranged on the support frame, and the two ends of the front and rear tensioning rollers are respectively matched with the belt seat bearings arranged on the support frame, and the front and rear tensioning rollers are respectively connected to the support frame through the front and rear oblique support rods distributed in an "eight" shape, so that the debris removing flannel cloth can be installed through the support roller group, and the debris removing flannel cloth is arranged in a trapezoidal shape, which is conducive to the debris removing flannel cloth moving with the rotation of the front and rear horizontal rollers while being supported by the front and rear tensioning rollers to complete the debris removal.

[0011] Furthermore, the driving assembly includes a power machine and a transmission box arranged on a support frame, the power machine main shaft is connected to the transmission box input shaft, and the transmission box output shaft is connected to one end of the roller shaft of the front horizontal roller or the rear horizontal roller extending outward with a seat bearing, so that the front horizontal roller or the rear horizontal roller can be driven to rotate by the power machine, thereby driving the debris removing cloth to remove debris.

[0012] Furthermore, the length of the fluff on the impurity-removing fluff cloth is set to 0.6-4 mm, and the fluff forms an angle of 5-45 degrees with the surface of the impurity-removing fluff cloth.

[0013] Furthermore, the support frame is arranged above the material conveyor through a lifting and adjusting component, and the lifting and adjusting component includes a plurality of vertical screws arranged around the bottom of the support frame, and the upper ends of the plurality of vertical screws pass through a first through hole arranged at the bottom of the support frame, and are screwed with nuts arranged at the upper and lower ends of the first through hole, and the lower ends of the plurality of vertical screws pass through a second through hole arranged on the material conveyor frame, and are screwed with nuts arranged at the upper and lower ends of the second through hole, so as to adjust the height of the impurity removing cloth according to the thickness of the material on the material conveyor, so that the impurity removing cloth is in full contact with the material, thereby ensuring the impurity removing effect.
