Below with reference to Fig. 1-Fig. 6 describe according to the embodiment of the present invention for spinning combing machine three on five times drafting systems.
According to the embodiment of the present invention for spinning combing machine three on five times drafting systems, comprising: roller 61 to 63 and pressue device 7 after front roller seat 1, back roller base 2, front pressure frame 3, rear pressure frame 4, the first to the 5th roller 51 to 55, front, neutralization.
As depicted in figs. 1 and 2, particularly, the front portion of back roller base 2 is connected with the rear portion of front roller seat 1.The left and right sides of front roller seat 1 is respectively equipped with first roller hole (not shown), and the left and right sides of back roller base 2 is respectively by vertical second to the 5th roller hole 521,531,541 and 551 that is sequentially with.
The rear portion of front pressure frame 3 is connected with back roller base 2 rotationally, and the rear portion of rear pressure frame 4 is connected with back roller base 2 rotationally.Front leather roller 61 is located on front pressure frame 3 rotationally, and medium rubber roller 62 and rear roller 63 are located on rear pressure frame 4 rotationally by vertical order.
As shown in Figure 3, in figure, the direction of arrow represents drafting of sliver direction, when rotating front pressure frame 3 and rear pressure frame 4 and pressurize to roller, make front leather roller 61 to first roller 51 pressurizations (the sliver at first roller 51 places being exerted pressure), 62 pairs second of medium rubber rollers and the 3rd roller 52,53 pressurizations (the sliver between the second roller 52 and the 3rd roller 53 being exerted pressure), 63 pairs the 4th of rear rollers and the 5th roller 54,55 pressurizations (the sliver between the 4th roller 54 and the 3rd roller 55 being exerted pressure).
As described in Fig. 1-3, pressue device 7 is located at first roller 51 and the second roller 52 tops and is positioned at the front end near the second roller 52, and pressue device 7 can upwards rotate.When pressue device 7 is pivotally lowered into position as shown in Figure 3, make pressue device 7 to first roller 51 and the pressurization of the second roller 52 (between first roller 51 and the second roller 52 and near the sliver pressurization of the front end of the second roller 52).
According to the embodiment of the present invention for spinning combing machine three on five times drafting systems, by pressue device 7, can increase frictional force and the cohesive force of sliver between first roller 51 and the second roller 52, therefore when combing machine high-speed cruising, can control better the motion of fiber in sliver and adapt to the fiber that length differs greatly, effectively improving the quality of combing sliver.
As shown in Figure 4 and Figure 5, according to one embodiment of present invention, pressue device 7 comprises: installing rack 71, mounting blocks 72, press-on pins 73, pressure bar 74, spacer pin 76 and pressurization slide block 75.
Particularly, two installing racks 71 are L shaped and L shaped one end and can upwards rotate on the inwall 21 of the left and right sides that is located at back roller base 2 by threaded 711.Two mounting blocks 72 are fixedly connected with installing rack 71 by screw 721 respectively.Press-on pins 73 is located at respectively the top of mounting blocks 72.Two spacer pins 76 are located at respectively on the inwall 21 of the left and right sides of back roller base 4 and are positioned at the below of mounting blocks 72, the angle rotating with installing rack 71 in order to limit mounting blocks 72.Pressurization slide block 75 is located at respectively on the front end 41 of both sides of rear pressure frame 4, and the position of pressurization slide block 75 is corresponding with the position of press-on pins 73.
The two ends of pressure bar 74 are fixedly connected with mounting blocks 72 respectively.When rear pressure frame 4 rotates, by pressurization slide block 75, promote press-on pins 73 to drive mounting blocks 72 to rotate, and then pressure bar 74 is rotated, until mounting blocks 72 offsets with spacer pin 76, the rotation of pressure bar 74 stops, and pressure bar 74 turns to predetermined angle.
Simple in structure according to the pressue device 7 of the drafting system of the embodiment of the present invention, take up room little, therefore can on three, in five lower traction equipments, install and control flexibly, reliable.
As shown in Figure 5, preferably, pressue device 7 also comprises: installing hole (not shown), spring 77 and jump ring 78.
Particularly, installing hole is located at respectively in mounting blocks 72 and is stepped hole.Spring 77 is located in stepped hole, and press-on pins 73 is through spring 77 and installing hole, so that spring 77 top and bottom offset with head and the installing hole bottom of press-on pins 77 respectively.Jump ring 78 is located at the afterbody of press-on pins 73.
Press-on pins 73 can move up and down by spring 77 and jump ring 78 in installing hole, has certain elasticity.When pressure bar 74 pressurization, pressure bar 74 can be made trickle adjustment according to the concrete condition of sliver, by press-on pins 73, makes trickle moving up and down, and realizes the fine setting of cotton sliver friction force and cohesive force, i.e. elastic pressurized.Thus, further improved the quality of sliver.
Cross section can for circular, oval or other special-shaped pressure bars 74 all can be useful according to the embodiment of the present invention for spinning combing machine three on five times drafting systems.
As shown in Figure 6, according to one embodiment of present invention, pressurization slide block 75 is provided with regulating tank 751.Pressurization slide block 75 was located on rear pressure frame 4 by screw and coordinating of regulating tank 751.By the cooperation position of screw and regulating tank 751, can regulate the height of pressurization slide block 75, thereby reach, regulate the suffered downward pressure of pressure bar 74, and then reach 74 pairs of sliver institute applied pressures of adjusting pressure bar.
Preferably, pressurization slide block 75 bottoms are provided with projection 752 and promote described press-on pins 73 to facilitate.
As shown in Figure 1, according to one embodiment of present invention, on the rear end of back roller base 2 by vertical the second support 23 and the first support 22 and the second support 23 of being sequentially with lower than the first support 22.The rear portion of front pressure frame 3 is located on the first support 22 rotationally, and rear pressure frame 4 is located on the second support 23 rotationally.Thus, forward and backward pressure frame 3,4 can not interfere.
As shown in Figure 1, according to one embodiment of present invention, back roller base 2 can be slided with respect to front roller seat 1 front and back, makes thus the drafting system of five times spinning combing machines on of the present invention three can further improve the adaptability of the cotton fiber that length is differed greatly, and has increased the scope of application.
