Description
Technical field
The present invention relates to spiral filament forming machine technical field, specially a kind of wrapping wire pressure heads mechanisms for heater strip.
Background technology
Screw rod is the important component of injection molding machine, its effect is that plastics are conveyed, be compacted, melt, stir and are pressed,
All these is all to rotate to complete in barrel by screw rod.When screw rod rotates, plastics are for machine tube inner wall, screw rod
It can all generate friction between screw channel bottom surface, spiral shell rib pressure surface and plastics and plastics and mutually move, plastics are pushed ahead
Exactly this movement combination as a result, in order to allow plastic melt, can wind that heater strip is convenient to heat plastics on screw rod,
However heater strip is usually all made of metal, hardness and strength are all higher, and the feeding head of existing spiral filament forming machine is difficult to add
Heated filament is pressed on the winding that heater strip is completed on screw rod, the raised out-of-flatness of heater strip winding.

In view of the above-mentioned problems, the present invention provides a kind of wrapping wire pressure heads mechanism for heater strip, it can be in wrapping wire
Heater strip is pressed on screw rod simultaneously, heater strip winds smooth rule.
Its technical solution is such：A kind of wrapping wire pressure heads mechanism for heater strip, including pressure head stent, the pressure head
Pedestal upper end is equipped with indenter device, and the indenter device includes the pressure head housing being arranged on the pressure head stent, the pressure head
The upper end of housing is equipped with cylinder, and the piston rod of the cylinder is extended downwardly into the pressure head housing, and the piston-rod lower end passes through
Link block is connected with connecting rod, and the connecting rod can rotate below the link block, and the lower end of the connecting rod is connected with feeding head,
Pressure head housing is stretched out in the lower end of feeding head, is set with gear on the connecting rod, the pressure head housing is connected with servo motor, described
The output shaft of servo motor is connected with screw by shaft coupling, and the screw is equipped with feed screw nut pair, the feed screw nut pair
Rack is equipped with close to the side of the gear, the rack is intermeshed with the gear, the opposite side of the feed screw nut pair
Positioning key is fixed with, the positioning key is corresponded on the pressure head housing and is equipped with the keyway to match with the positioning key, it is described fixed
Position key is embedded in the keyway.
Further, the pressure head pedestal lower end is equipped with mounting base.
Further, the cylinder is mounted on the pressure head housing upper end by fixed block.
Further, the link block lower end is equipped with T-slot, and small end is equipped with T-shaped block, and the T-shaped block is installed on T shapes
Connecting rod enable in slot in link block rotated down.
The wrapping wire pressure heads mechanism for heater strip of the present invention, when winding heater strip, servo motor driving screw rotation,
Under the limitation of positioning pin, the feed screw nut pair on screw moves on screw, and the rack and pinion on feed screw nut pair occurs
So as to be rotated with moving gear, the feeding head being connected with gear rotates therewith for relative movement, carries out wrapping wire in screw surface, passes through
Cylinder drives connecting rod that can press to feeding head so that the heater strip of winding, which all compresses, to be fitted on screw rod, and wrapping wire will not protrusion
Out-of-flatness, wrapping wire effect is good, solves the problems, such as heater strip winding.
