Description
Technical field
This utility model relates to vane technical field, a kind of point-to-point regulation double air ports vane.
Background technology
The cooling vane being currently used for blown film has single air port, double air ports various ways, its purpose is to provide film bubble
The most sufficiently cooling, reduces the impact that thin film thickness degree is caused by cooling wind, improves the thickness degree of thin film.In actual production
In, after vane provides the cooling wind of even circumferential, the thickness degree of thin film is often depending on the designing and manufacturing level of mould.Mould
The thickness degree of thin film also can only be brought up to certain limit by designing and manufacturing level, and due to runner reason, thin film is the most often
There is thickness road；Thickness road to be eliminated, improves the thin film thickness uniformity further, and current vane is difficult to solve this problem.
Patent searching 200420038818.4 air ring of blowing regulatable blow moulding machine, its technology and this utility model have very big difference, and it is adopted
With along vane even circumferential distribution radial hole as air channel, the thin film thickness of corresponding point can be regulated, but as the aperture in air channel
It is to be interrupted in circumference distribution radially, regulates circular slab in there is no transition body, and hole at air inlet and air outlet and adjusting
Wind direction can be changed during air quantity.Accordingly even when regulate each air duct hole onesize, circumference air quantity is also difficult to uniformly, and air port is flowed
Amount is also difficult to stable, and before adjusting vane, the adjustment in advance for die head causes difficulty；Secondly, vane point of adjustment and thickness in film bubble
Road correspondence is inaccurate, regulation difficulty.And it is single air port vane, there is cooling air quantity little, low the asking of cooling effectiveness
Topic.The manual adjustable air ring of patent searching 2012203670656, although it is double air ports vane forms, but what its regulation controlled
It is only uptake, so, when the thickness road deviation in film bubble is bigger, though to reduce thickness inclined in the air quantity regulation in an air port
Difference, but air quantity range of accommodation is little, sometimes still the regulation of thickness point can not be come when reaching accommodation limit position, not reach satisfaction
Regulating effect.

Fig. 2 is the little air channel of this utility model and prismatic boss scheme of installation.
In figure: 1 leeward lip, 2 apoplexy lips, 3 windward lips, 4 dispensing body, 5 regulation screw, 6 distributed amongst bodies, 7 pins, 8 wind
Ring upper cover, 9 vane lower covers, 10 blast pipes, 11 dividing plates, 12 little air channels, 13 prismatic boss.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of point-to-point regulation double air ports vane, including
Leeward lip 1, the outer wall of described leeward lip 1 has installing hole, and the inner chamber of installing hole is plugged with pin 7, the top of described pin 7
Being connected with distributed amongst body 6, the right side of described distributed amongst body 6 is provided with apoplexy lip 2, and the left side of described leeward lip 1 is provided with
Vane lower cover 9, is provided with dividing plate 11 at the center of top of described vane lower cover 9, and the outer wall of described dividing plate 11 to have filter wind little
Hole, the top of described vane lower cover 9 is fixedly installed vane upper cover 8, and the bottom of described vane lower cover 9 has air vent, and logical
The bottom of air holes is provided with the blast pipe 10 matched with air vent, and the right side of described vane upper cover 8 is provided with dispensing body 4, institute
The bottom connection stating dispensing body 4 has prismatic boss 13, the outer wall of described dispensing body 4 to have little air channel 12, described little air channel 12
Inner chamber is provided with regulation screw 5, and the right side of described dispensing body 4 is provided with windward lip 3.
Wherein, described regulation screw 5 is positioned at little air channel 12 air inlet, and the inwall in described little air channel 12 is provided with interior spiral shell
Stricture of vagina, the outer wall of described regulation screw 5 is provided with the external screw thread matched with female thread, operationally, can be by regulation screw 5
Come for thick point and thin point present on thin film.
Operation principle: this utility model uses tangential air intake form, is sent into wind by vane upper cover 8 and vane lower cover 9 groups
The annular wind chamber become, and rotates homogenizing, with after the filter wind aperture of dividing plate 11 distribution on vane lower cover 9 obtain even circumferential and divide
The not rotary wind of cloth, enters dispensing body 4, and air channel is divided into the little air channel of several radial distribution 12, is divided by centre by dispensing body 4
Being classified as upper and lower two-way after part 6, a road enters lower air port, and another road enters uptake, and each little air channel 12 is by prismatic boss
13 intervals form, and make air inlet and the air outlet transition connection in little air channel 12, and regulation screw 5 is positioned at little air channel 12 air inlet,
Can regulate vertically, when original state, regulation screw 5 is positioned at same intermediate altitude, is fixed by each little air channel 12 air outlet
Onesize, the most each little air channel 12 air quantity is consistent, is now equal to common double air port vane.
During blown film, according to thin film thickness, first adjust die head, upper and lower air port is adjusted to correct position, measure thin film
Thickness degree, then find and thick point and thin corresponding regulation screw 5, regulate the regulation screw of corresponding point respectively, at thick point, regulation
Screw 5 regulates downwards, and corresponding radially little air channel 12 reduces, and corresponding point uptake and lower tuyere air volume reduce simultaneously, and cooling reduces,
Film thining；At thin point, regulation screw 5 is adjusted up, and corresponding radially little air channel 12 increases, corresponding point uptake and leeward one's intention as revealed in what one says
Amount increases simultaneously, and cooling strengthens, film thick, and so, it is right that thin film thickness point and thin some air quantity all can be carried out by upper and lower air port simultaneously
Should regulate, the air quantity range of accommodation of thick point and thin point maximizes and allows thin film reach the preferable thickness uniformity.
Embodiment the most of the present utility model, for the ordinary skill in the art,
