Description

Combined type impurity removing device suitable for opening and cleaning equipment

Technical Field

The utility model relates to the field of textile machinery, in particular to combined type impurity removing device of opening cotton or scutching equipment with open edulcoration function suitable for opening clear equipment.

Background

The opening or scutching equipment is one of the main machines of the scutching and carding combination machine and has the functions of opening and removing impurities of raw materials. The edulcoration device is the essential structure of opening cotton or scutching equipment.

At present, the impurity removal device of cotton opening or cotton cleaning equipment mainly has two kinds: a dust grid type impurity removing device and a dust removing knife suction type impurity removing device.

The dust format impurity removing device is as shown in figures 1 and 2: a plurality of triangular dust bars 9 with brackets (hereinafter also referred to as dust bars) between the frame wall boards 7a and 7b form a dust grid, positioning screws 6a and 6b are arranged at two ends of each dust bar, and the dust bars can rotate around the axes of the positioning screws. A pin screw 5 connects the adjustment plate 10 to the dirt bar bracket. The adjusting plate 10 is provided with a long round hole, and an eccentric shaft of the adjusting eccentric shaft 3 slides relatively in the long round hole. Therefore, the triangular dust rod 9, the adjusting plate 10 and the adjusting eccentric shaft 3 form a connecting rod-sliding block mechanism. The operating handle 1 is rotated to drive the adjusting ring 2 and the adjusting eccentric shaft 3 to rotate together, and drive the adjusting plate 10 to do combined movement of rotation and up-and-down movement, so that the triangular dust rod 9 is driven to rotate around the positioning screws 6a and 6b, the interval between the dust rods, the installation angle of the dust rods and the distance between the dust rods and the opening beater 8 are changed, and the cotton falling amount is changed.

The working principle of the dust grid type impurity removing device is as follows: the cotton piece is opened and is strikeed the dirt stick through opening the hired roughneck after, makes the great impurity that contains in the cotton piece peel off out, and under centrifugal force and impact effect, impurity is thrown away out the dirt check, falls into the dirt room, is sucked to the dirt system of straining by the negative pressure again. According to different raw materials and different impurity dropping process requirements, the interval between the dust bars of the triangular dust bars, the installation angle of the dust bars and the distance between the dust bars and the opening beater can be adjusted outside the machine, so that the cotton dropping amount can be effectively controlled. The noil of the dust grid type impurity removing device contains more impurities which are big impurities and mainly comprise seed cotton, soft seeds, broken seeds, sterile seeds, seed shells, cotton branches and the like. Because the dust grid type impurity removing device adopts the modes of 'impacting' and 'centrifuging' impurity removing, the possibility of smashing large impurities is low. The 'big impurity early fall and little breakage' is one of the basic requirements of blowing-carding spinning.

The suction opening type impurity removing device of the dust removing knife is as shown in figures 3 and 4: the device consists of a carding plate 14, an adjusting plate 13, a dust removing knife 15, a wind shield 12 and an air suction pipe 11. The adjusting plate 13 can rotate around the tail end shaft core, and the distance between the top end of the adjusting plate and the opening beater 16 is changed. According to the process requirements, the adjusting plate 13 is rotated outside the machine to adjust the distance between the top end of the adjusting plate and the opening beater 16, thereby adjusting the amount of the noil. The noil enters the suction pipe 11 with negative pressure along the direction K along with the airflow and returns to the dust filtration system.

The working principle of the dust removing knife suction opening type impurity removing device is as follows: the fed cotton bundles are combed by an opening beater and a carding plate, so that the connection of impurities and fibers is broken, under the separation action of high-speed centrifugal force, an airflow boundary layer and a dust removing knife, fine impurities, short velvet, micro dust and fibers are separated, and the impurities, the short velvet and the micro dust are sucked away by an air suction pipe. Due to the continuous suction of the air suction pipe, impurities are actively dropped, and the effects of removing short fibers, tiny dust and small impurities are improved. The dust removing knife suction type impurity removing device replaces beating with a comb, can effectively remove fine impurities, short velvet and tiny dust, and creates favorable conditions for next carding and spinning.

The opening and picking process is generally divided into preliminary opening and fine opening. The impurity removal of the preliminary opening equipment generally adopts a dust grid type impurity removal device with large spacing. The edulcoration of meticulous opening equipment generally adopts the less dust removal sword suction type edulcoration device of gauge length. After the primary opening equipment opens and removes the impurities, part of the large impurities can not be effectively removed, so that the large impurities are further removed on the fine opening equipment in advance, and then the small impurities are removed in a fine mode, so that the situation that the large impurities are combed under a structure with a small space distance and are damaged to generate more fine impurities is avoided.
