Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further.
Machine control double needle as Fig. 2 to 4 extrudes control device, and its driving means not adopts the Mechanical Driven of impacting type,
But be driven using another stand-by motor 50, stand-by motor 50 is installed on the surface of extruder motor 1, and non-extruded is electric
The left and right sides of machine 1, does not produce excessive impact to the transverse shifting of wire feeder.
Machine control double needle extrusion control device in the present embodiment, including fixed mount, extrusion roller 10, extruder motor 1 and
Swing hold-down mechanism, swing hold-down mechanism and include drive component, the first swing arm 21, the second swing arm 22 and control the first swing arm 21 same
The contrary reverse geometry of second swing arm 22 moving direction, the first swing arm 21 and the setting of the second swing arm 22 specular, the first swing arm
21 and second swing arm 22 slide in fixed mount surface, the first swing arm 21 is provided with the first pinch roller 210, and the second swing arm 22 is provided with the second pressure
Wheel 220, the first pinch roller 210 and the second pinch roller 220 are located at the both sides of extrusion roller 10.Two pinch rollers are crowded by being pressed in strands
Going out roller 10 surface, extruder motor 1 rotates afterwards makes extrusion roller 10 rotate, thus driving strands to move, extruding roller 10 table
Face is provided with the broached-tooth design for increasing friction.
Reverse geometry includes fork 5, and drive component includes the driver element for controlling fork 5 pendulum angle, fork 5
Hinged first swing arm 21 in two ends and the second swing arm 22, the first swing arm 21 and the second swing arm 22 are equipped with and move back and forth for it
Limit sliding chutes 23, are provided with position-limiting unit in limit sliding chutes 23, position-limiting unit is fixed with fixed mount phase.
Driver element can be driven using cylinder, motor or other devices, because motor operation is reliable and stable, this reality
Apply preferred motor in example to be driven；Position-limiting unit can be carried out spacing, due to spacing using the various ways such as slide block, spacer pin
Pin cost is relatively low, and is easy to dismount, and therefore the present embodiment position-limiting unit adopts spacer pin.
Stand-by motor 50 connects the middle part of fork 5, controls fork 5 rotating by stand-by motor 50, thus controlling first
The stroke of swing arm 21/ second swing arm 22, and then control the first pinch roller 210/ second pinch roller 220 to the spacing of extrusion roller 10.
In order to reduce volume, fork 5 is made to be close to fixed mount surface, since it is considered that fork 5 may stop strands
Pass through, therefore the through hole passing through for strands or groove are set on fork 5 surface.
It is provided with seal wire block 6, seal wire block 6 upper end is provided with entrance 61, seal wire block 6 lower end is provided with outlet 62 below fork 5,
Entrance and exit is attached by centre by silk guide passage 60, and silk guide passage 60 has two, for passing through of both threads material,
Play an elicitation effect to strands.
Spacing between silk guide passage 60 from top to bottom diminishes, and outlet 62 positions are corresponding with nozzle position, due to two
Spacing between entrance 61 is larger, and therefore strands, when putting into entrance 61, can keep larger spacing, excessively tight without row
Gather, if spacing is too small, easily make strands tangle up.
Secondly, silk guide passage 60 can also be dredged to the movement of strands, makes position and the silk guide passage 60 of strands
Position is corresponding, more stable when strands pull downward on, and is not likely to produce knuckle or bending, leads to strands to be difficult to be extruded roller and draw
Dynamic.
Double needle extrusion control device in the present embodiment, when using, similarly has three state：Left and right two ends are all stopped
Only state, left end discharge state, right-hand member discharge state.
The equal halted state in left and right two ends：As shown in Fig. 2 when fork 5 is turned to level by stand-by motor 50, the first swing arm
21 and the second swing arm 22 mobile to identical position, the distance of the first pinch roller 210 of now the first swing arm 21 to extrusion roller 10,
Identical to the distance of extrusion roller 10 with the second pinch roller 220 of the second swing arm 22, this distance is more than the diameter of strands, two pressures
Strands all cannot be pressed on extrusion roller 10 surface by wheel, and extrusion roller rotates and strands cannot be driven to move.
Left end discharge state：As shown in figure 3, when stand-by motor 50 rotates counterclockwise, fork 5 left end moves down right-hand member
Move up, the first pinch roller 210 is compressed downwardly near extrusion roller 10, and strands are pressed in the first pinch roller 210 and extrusion rolling
Between wheel, the second pinch roller 220 lifts to upper right side, increases with the distance of extrusion roller 10, strands are not subject to the second pinch roller 220 He
The pressure of extrusion roller 10, extrudes roller 10 afterwards and rotates counterclockwise in the presence of extruder motor 1, strands are squeezed from left side mouth
Go out.
Right-hand member discharge state：As shown in figure 4, identical with left side discharge state, it is merely only the rotation side of stand-by motor 50
To for rotating clockwise.Remaining runs and is mirror image with left end discharge state, does not therefore do the explanation of repetition herein.
Advantage of this embodiment is that：Stand-by motor 50 is positioned over the surface of extruder motor 1, for a left side for extruder motor
Right both sides no affect so that whole moving left and right of wire feeder is not affected.Secondly, the control of stand-by motor 50 is accurate, this
Freely switching right and left discharging, low noise can be carried out by stand-by motor 50 in embodiment, and be hardly damaged.
The above makes preferred embodiment of the present utility model, for the person of ordinary skill of the art without departing from
On the premise of the utility model principle, some modifications and improvement can also be made, these also should be regarded as protection of the present utility model
