Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2 and Fig. 3: get fine device, comprise and longitudinally get fine unit 1 and get fine unit 2 with vertical, longitudinally get fine unit 1 to be positioned at and vertically to get above fine unit 2, longitudinally getting fine unit 1 comprises die 11, die 11 is corresponding with the upper roll wheel 3 of carding machine to be arranged, and namely die 11 is positioned at the intercardinal outside of upper roll wheel 3 side of carding machine; The direction of motion of die 11 and horizontal plane.
In order to die 11 can peel off fiber from upper roll wheel 3 smoothly, die 11 is 0.2mm with close one end of upper roll wheel 3 and the distance of upper roll wheel 3, and the vibration frequency of die 11 is 900 times/min.。When the single fiber that carding machine combing obtains is delivered to die 11 position through upper roll wheel 3, die 11 high-speed motion forms air-flow, and the fiber spin-off be attached on upper roll wheel 3 can get off by this air-flow.Fiber after longitudinally getting fine unit 1 and peeling off, without collecting drum, obtains the basically identical fiber in direction after the air-flow of vertical level peels off upper roll wheel 3.
Longitudinally getting fine unit 1 also comprises foraminous conveyer 12, and upper foraminous conveyer 12 is horizontally disposed with, and is positioned at below die 11.
The fiber obtained after die 11 is peeled off drops on upper foraminous conveyer 12, and the orientation of fiber is that longitudinally (namely vertical with the direction of motion of upper foraminous conveyer 12) arranges.Because the vibration frequency of die 11 is 900 times/min, can form enough air-flows at upper roll wheel 3 and the gap location of die 11 when die 11 is moved, the fiber in realization on foraminous conveyer 12 is peeled off in the same direction by air-flow.Die 11 motion frequency is too small, then the fiber on upper foraminous conveyer 12 cannot be peeled off; Die 11 motion frequency is excessive, then the air-flow formed is too strong, and the fiber after peeling off cannot be dropped on upper foraminous conveyer 12 in the gap between upper roll wheel 3 and die 11.
Vertically get fine unit 2 and comprise screen cloth roller 21, screen cloth roller 21 is corresponding with the lower roll wheel 4 of carding machine to be arranged, and namely screen cloth roller 21 is positioned at the side of lower roll wheel 4, can adsorb the fiber that lower roll wheel 4 is carried.Screen cloth roller 21 inside is provided with roller 5, and roller 5 remains and maintains static, and roller 5 offers air inlet 6, and air inlet 6 is positioned at lower roll wheel 4 side.In use, the gas of air inlet 6 periphery enters into the inner side of roller 5 through the outside of screen cloth roller 21, formed to the air-flow inside roller 5, thus form negative pressure at screen cloth roller 21 and air inlet 6 opposite position, to make on lower roll wheel 4 fiber of attachment can be adsorbed by screen cloth roller 21, and rotate along with screen cloth roller 21.
The external diameter of screen cloth roller 21 is 200mm, and roller 5 external diameter is 190mm, and the external diameter of screen cloth roller 21 is less than the external diameter of lower roll wheel 4, and the width of air inlet 6 is 100mm, and the order number of screen cloth roller 21 is 80 orders.Screen cloth roller 21 is inconsistent with the external diameter of roller 5, there is gap, the gas at air inlet 6 place can be entered from outward smoothly between screen cloth roller 21 and roller 5.
Vertically get fine unit 2 and also comprise lower foraminous conveyer 22, lower foraminous conveyer 22 is positioned at the below of screen cloth roller 21, and lower foraminous conveyer 22 offers air entry 7.Air entry 7 carries out air-breathing, make lower foraminous conveyer 22 upper surface formed negative pressure, when fiber turns to the top of air entry 7 along with screen cloth roller 21, the negative pressure formed by air entry 7 by fibers adsorption on lower foraminous conveyer 22.Due to air entry 7, place has downward adsorption gas flow, and is vertically peeled off by the fiber on lower roll wheel 4 during air inlet 6 place, and therefore, the fiber absorbed finally by air entry 7 keeps down plumbness, namely keeps and horizontal plane.
Through the fiber obtained after fine device is produced of getting of the present utility model, there is longitudinal and vertical both direction, then the nonwoven fabric with bidirectional guide function can be obtained after subsequent handling bonding, liquid can spread rapidly to both direction by this nonwoven fabric, prevent liquid from accumulating, can be used in paper diaper for infant, prevent stockpiling and preventing urethral leakage of urine, water conservancy diversion is effective.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
