Description
Technical field
The utility model belongs to extrusion moulding equipment technical field more particularly to a kind of die head automatic regulating apparatus.
Background technique
In shrink film production process, if even by female non-uniform film thickness that extruding machine and die head are produced, just need
The thickness of female film is adjusted, the adjustment of female film thickness is realized generally by the die lip gap of control annular die head
, the control for female film thickness is a kind of small regulative mode, relatively high to the required precision of equipment.
Existing die head adjustment device is generally used the regulative mode of mouth mold overall movement, can not adjust the part of die head
Gap, Adjustment precision is low, inconvenient for operation, influences the thickness uniformity for producing film.
Utility model content
Place in view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of moulds that Adjustment precision is high
Head outlet gap automatic regulating apparatus.
For the attainment of one's purpose, technical solution provided by the utility model are as follows:
The utility model provides a kind of die head automatic regulating apparatus, and the die head automatic regulating apparatus is set to below die head
The outside of die lip, die head automatic regulating apparatus form ring structure around the die lip by multiple micro-adjusting mechanisms, and micro-adjusting mechanism is logical
Mounting rack is crossed to connect with die head；The micro-adjusting mechanism includes pull rod, thermal expansion pipe, electrical bar, fixed block, pre-tightens screw and drawing
Hook, the thermal expansion pipe are set in pull rod, and electrical bar is set in thermal expansion pipe, and thermal expansion pipe passes through spiral shell close to the side of die lip
Bolt is fixed on mounting rack, and the preload screw is mounted on one end of pull rod by fixed block, pre-tighten screw by jacking block with
Thermal expansion pipe connection, described drag hook one end are fixed on pull rod, and the other end is fixed on die lip.
Preferably, fixed plate is equipped with below the pull rod, thermal expansion pipe is leaned on near-lying mode by bolt by the fixed plate
The side of lip is fixed.
Using technical solution provided by the utility model, compared with prior art, have as the utility model has the advantages that
1, the adjustment device in the utility model is looped around around die lip, can be accurately located opening for die lip certain point
Mouth size.
2, the utility model can accurately control the thickness size of female film using micro-adjusting mechanism, improve the production matter of film
Amount.

Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
According to Fig. 1 to Fig. 3, the present embodiment is related to a kind of die head automatic regulating apparatus, the die head adjust automatically
Device is set to the outside of 1 lower section die lip 4 of die head, and die head automatic regulating apparatus is made of multiple micro-adjusting mechanisms 3 around the die lip 4
Ring structure, micro-adjusting mechanism 3 are fixedly connected by mounting rack 2 with die head 1.
The micro-adjusting mechanism 3 includes pull rod 31, thermal expansion pipe 32, electrical bar 33, fixed block 34, pre-tightens screw 35 and draw
Hook 36, the thermal expansion pipe 32 are set in pull rod 31, and electrical bar 33 is mounted in thermal expansion pipe 32, and thermal expansion pipe 32 leans on near-lying mode
The side of lip 4 is fixed on mounting rack 2 by bolt 5, and the preload screw 35 is mounted on pull rod 31 by fixed block 34
One end pre-tightens screw 35 and is connect by jacking block 37 with thermal expansion pipe 32, and described 36 one end of drag hook is fixed on pull rod 31, another
End is fixed on die lip 4.Fixed plate 7 is equipped with below the pull rod 31, the fixed plate 7 passes through bolt 5 for thermal expansion pipe
32 fix close to the side of die lip 4.
Utility model works principle:
After plastics come out from die head runner 6, passes through, formed after supercooling female from the center of die head automatic regulating apparatus
Film is controlled, electric heating when detecting that female film somewhere film thickness is not up to standard using electrical bar 33 of the controller to corresponding position
After the heating of stick 33 or cooling, so that 32 expanded by heating of thermal expansion pipe or cooling meat, when 32 expanded by heating of thermal expansion pipe, pass through top
Block 37 will pre-tighten screw 35 and eject outward, fixed due to pre-tightening screw 35 and pull rod 31, pre-tighten screw 35 for pull rod 31 toward outside
It draws, while the drag hook 36 fixed with pull rod 31, by die lip 4 also outside side stretching, the gap of 4 die head runners 6 of die lip becomes larger, modeling
The load of material melt also correspondingly increases therewith, otherwise when 32 cooling meat of thermal expansion pipe, then the load of plastic melt
It correspondingly reduces therewith, so that the thickness of female film at this is adjusted, reach prescribed requirement.It is evenly distributed on each around die lip
A automatic regulating apparatus works by this principle, so that the melt after making outflow get to know is more uniform, and then has reached automatic
The problem of adjusting female film thickness uniformity.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
