Abstract
A mechanical type cutting knife relates to the field of structures of side cutting devices of non-woven fabrics and comprises a dovetail groove connected onto a machine frame, wherein the dovetail groove is connected with a middle shaft sleeve, the upper end of the middle shaft sleeve is connected with a pressing cover, the upper end of the pressing cover is connected with a bolt by virtue of a thread, one vertically arranged middle shaft penetrates through the middle shaft sleeve and the pressing cover, the middle shaft is arranged under the bolt, and a dish-shaped spring and a gasket are arranged between the bolt and the middle shaft. The lower end of the middle shaft sleeve is connected with a shaft sleeve boss, the middle shaft is connected with a middle shaft boss, and a spiral spring is arranged between the middle shaft boss and the shaft sleeve boss. The lower end of the middle shaft is connected with a small shaft support, the small shaft support is arranged under the middle shaft sleeve, a transversally arranged small shaft is supported on the small shaft support, the small shaft in the small shaft support is connected with a blade seat by virtue of a bearing, and a blade is connected onto the blade seat. With adoption of the mechanical type cutting knife, pressure can be randomly adjusted according to thickness of cloth, and the pressure is stable. Cut thickness can reach up 1000g/m<2>, thereby making up defects of compressed air cutting knives.
Description
Technical field
The utility model relates to the structure field of the trimming device of nonwoven fabric.
Background technology
Previously used cutting knife, pressure be from compressed air, and compressed-air actuated pressure does not just reach requirement when the thickness of nonwoven fabric surpasses 300 g/ms, thus be difficult to cut edge, and compressed air when unstable difficulty larger.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of and can arbitrarily regulate pressure according to the thickness of cloth, and the mechanical type cutting knife of pressure stability.
The purpose of this utility model is achieved in that the mechanical type cutting knife, comprise the dovetail groove that is connected on the frame, dovetail groove connects bottom bracket axle, the upper end of bottom bracket axle connects gland, the upper end threaded connection bolt of gland, place the same vertical axis of arranging in described bottom bracket axle and the gland, axis is arranged on the below of bolt, and disk spring and pad are set between bolt and the axis; The lower end disjunctor of described bottom bracket axle arranges the axle sleeve boss, and disjunctor arranges the axis boss on the axis, between axis boss and the axle sleeve boss helical spring is set; The lower end of described axis connects little bracing strut, and little bracing strut is arranged on the below of bottom bracket axle, connects blade bearing by bearing on the little axle in the little axle of a lateral arrangement of little bracing strut upper support, little bracing strut, connects blade on the blade bearing.
The utility model is used for the side cut of nonwoven fabric, and its dovetail groove is installed on the frame of nonwoven fabric lapper, and cutting knife can be fixed.The steel rider (being called bed plate, by the driven by motor transmission) of one ￠ 270 is arranged below the blade, and nonwoven fabric passes between blade and bed plate.When bolt was screwed down, axis was and then downward, until reach certain pressure between blade and the bed plate.When bed plate was rotated by driven by motor, because the effect of frictional force, blade squeezed nonwoven fabric and opens, simultaneously also thereupon motion, thus cut nonwoven fabric.Cylindrically coiled spring makes cutting knife have certain stroke, and disk spring can guarantee to have certain elasticity between blade and the bed plate, plays a protective role.
The utility model can arbitrarily be regulated pressure according to the thickness of cloth, and pressure stability.The thickness of cutting can reach 1000 g/ms, has remedied the deficiency of compressed air cutting knife.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that Local map is looked on the left side of Fig. 1.
Among the figure, 1 bolt, 2 disk springs, 3 pads, 4 glands, 5 helical springs, 6 axis, 6-1 axis boss, 7 bottom bracket axles, 7-1 axle sleeve boss, 8 little bracing struts, 9 blade bearings, 10 bearings, 11 little axles, 12 nonwoven fabric, 13 bed plaves, 14 blades, 15 nuts, 16 frames, 17 dovetail grooves.
The specific embodiment
As shown in Figure 1, 2, be the mechanical type cutting knife, comprise the dovetail groove 17 that is connected on the frame 16, dovetail groove 16 connects bottom bracket axle 7, the upper end of bottom bracket axle 7 connects gland 4, and the upper end threaded connection bolt 1 of gland 4 places the same vertical axis 6 of arranging in bottom bracket axle 7 and the gland 4, axis 6 is arranged on the below of bolt 1, and disk spring 2 and pad 3 are set between bolt 1 and the axis 6.The lower end disjunctor of bottom bracket axle 7 arranges axle sleeve boss 7-1, and disjunctor arranges axis boss 6-1 on the axis 6, between axis boss 6-1 and the axle sleeve boss 7-1 helical spring 5 is set.The lower end of axis 6 connects little bracing strut 8, little bracing strut 8 is arranged on the below of bottom bracket axle 7, the little axle 11 of a lateral arrangement of little bracing strut 8 upper supports connects blade bearing 9 by bearing 10 on the little axle 11 in the little bracing strut 8, connects blade 14 by nut 15 on the blade bearing 9.The steel rider (being called bed plate 13, by the driven by motor transmission) of one ￠ 270 is arranged below the blade 14, and nonwoven fabric 12 passes between blade 14 and bed plate 13.
