CN2340600Y - High performance filtering nozzle of jet moulder - Google Patents

Abstract

The utility model relates to a nozzle device with the functions of high efficiency and filtering of a jet molding machine. The spray outlet point of a material conveying pipe is provided with a nozzle, and the front end of the nozzle is screwed with a nozzle head. A filtering core is arranged in the nozzle, and the material feeding end of the filtering core forms a centralization opening in the shape of a horn opening. The centralization opening extends into the filtering core to form an inner flow passage, and the periphery of the inner flow passage is provided with a plurality of material guiding openings which are slantwise penetrated along the flow direction of plastics. The outlet points of the material guiding openings form concave material guiding grooves, so the plastics flow into the inner flow passage from the centralization opening, are slantwise guided to the material guiding grooves from the material guiding openings, and flow out towards the direction of the nozzle, and foreign matters are filtered.

Description

Spray nozzle device with Jet forming machine of high efficiency filter function

The utility model relates to a kind of spray nozzle device of Jet forming machine.

In the nozzle of plastics Jet forming machine; filter is not set at first; plastics can directly be injected in the mould via nozzle like this; the effect that does not promptly have any filtering impurity; for regeneration or secondary raw material; because regeneration or secondary raw material are to exercise the plastics of using after waste material is made or recycled again; the inevitable purer raw material of its waste material that includes increases; so the nozzle of the secondary raw material of these regeneration of use or recovery in jet-out plastic simultaneously; its impurity in plastics promptly enters in the mould in the lump with plastics, not only can influence the quality of moulding, and the easier running channel of being correlated with that makes blocks; and must clear up mould; and the spout of nozzle itself is also very easily blocked by its impurity, must clear up often, not only takes normal shutdown and deals with; cause the inconvenience in many uses; more form the waste of unnecessary financial cost,, enter in the mould to stop impurity so there is the dealer in its nozzle, to be equipped with the filtering element (cartridge) of filtering effect in addition; precisely because its disappearance that can't overcome is still arranged on the structure, necessity of improvement is also arranged.

Please cooperate shown in Figure 4, known structure is the ejiction opening 11 that is set as the opening shape in conveying pipeline 10 front ends, and be provided with a nozzle 20 in its ejiction opening 11 place's spiral shells, and be provided with a nozzle head 30 in the in addition end spiral shell of nozzle 20, and be installed with a filtering element (cartridge) 50 in addition in the inner radius of nozzle 20, the structure of its filtering element (cartridge) 50 includes solid large-diameter portion, and be provided with the honeycomb duct 51 of straight shape or helical form in its large-diameter portion, and be set as the guiding gutter 520 of depression at interval in choked flow wall 52 tops of honeycomb duct 51 both sides, directly cross water conservancy diversion for plastics, and in the honeycomb duct 51 terminal stop edges 521 that form height, make plastics flow to nozzle head 30 ejections by guiding gutter 520 another honeycomb ducts 51 of inflow through stopping again, and the impurity in its plastics is stopped by guiding gutter 520 simultaneously, and goes outflow honeycomb duct 51 again by nozzle head 30 ejections through the plastics of filtration.

Above-mentioned structure has following disappearance, as:

1, filtering time power consumption is too high: because plastics are during through filtering element (cartridge) 50; the flowing of its plastics is around filtering element (cartridge) 50 actions; precisely because the direction that the direction that flows and former pusher are advanced or for vertical or be oblique form, but not be forward a form, unnecessary power consumption caused; so form the waste on the energy; relative, more cause the pressure of pusher excessive, and the destruction of easily causing other structures; must often spend the cost of maintenance or renewal part, not meet the benefit of economy in fact.

2, filtering poor effect: because the filtering effect of its filtering element (cartridge) 50 is to be stopped by guiding gutter 520, very limited of its effect is confined to a certain little part, and the space is too small, will inevitably cause obstruction, and needs often cleaning, so necessity of improvement is arranged.

The purpose of this utility model is to provide a kind of spray nozzle device with Jet forming machine of high efficiency filter function, can under the state that does not influence the plastic flow direction plastics be filtered, and filter effect is good and be convenient to cleaning and use.

The technical solution of the utility model is:

A kind of spray nozzle device with Jet forming machine of high efficiency filter function is to be provided with ejiction opening in the conveying pipeline front end, and is provided with a nozzle in ejiction opening place spiral shell, and be provided with a nozzle head in the spiral shell of holding in addition of nozzle, and be installed with a filtering element (cartridge) within nozzle, it is characterized in that:

This filtering element (cartridge) is provided with the poroid concentrated mouth of loudspeaker and is communicated with ejiction opening in the place, end of charging, and concentrate mouthful from the end of path in filtering element (cartridge), extend to form one microscler within runner, and be provided with several oblique material guide ports that run through of in line shape in the inner flow passage periphery, and filtering element (cartridge) is recessed to form a deflector chute in the exit of material guide port.

Effect of the present utility model is:

1, filtering is speed and convenience: because the direction of each structure water conservancy diversion of its filtering element (cartridge) 40 is all suitable with plastic flows, all identical by the concentrated mouth 41, inner flow passage 42, the material guide port 43 that enter filtering element (cartridge) 40 with the direction that plastics are advanced with deflector chute 44, so, the speed of its plastics water conservancy diversion must be accelerated, and, the mode that material guide port 43 blocks impurity is quick and certain in the mode of directly blocking, so the effect of its filtering is good.

2, cleaning is convenient: flow out because the mode of filtering element (cartridge) 40 chargings is mouthfuls 41 small-caliber ends that enter again by inner flow passage 42 of concentrating by the heavy caliber end, so amass impurity in inner flow passage 42 in when clearing up, after as long as nozzle head 30 outwarded winding, filtering element (cartridge) 40 can be taken out, the mouth 41 of concentrating with the heavy caliber end directly knocks downwards and can clear up again, and the convenience of ten minutes is quick in the operation.

3, filter effect is good: because the utility model is the operation that stops impurity in the material guide port 43 of inner flow passage 42 inner peripherals to be covered with, it is to be a comprehensive impurity form of blocking, but not be the structural form of a locality or unicity, so very good on the filter effect.

For further understanding the structure of the utility model, feature and purpose thereof, now with preferred embodiment attached with graphic detailed description as the back:
