Abstract
A spray head is used to spray hot-melted material which is then solidified to form millimetre-sized pellets. The middle of a spraying side of the spray head is raised outwards; the circumference of the spraying side gradually becomes thicker than the middle; or the spraying side is provided with spray holes, each of which comprises an external hole and an internal hole; the diameters of the external holes are equal; the diameters of the internal holes are equal; the diameter of the internal hole is larger than the diameter of the external hole; and the internal holes of the middle of the spraying side gradually become deeper than the internal holes of the circumference. Consequently, the material sprayed out from the center of the spraying side can receive low resistance, and therefore can be sprayed far, and the material sprayed out from the circumference of the spraying side can receive high resistance, and therefore can be sprayed near, so the spherical granules sprayed out from different levels cannot be collided with one another and stuck together. The spray head has the advantages of simple structure, low processing cost, good shaping effect and high production efficiency.
Description
Technical field
The utility model relates to a kind of shower nozzle, in particular for the material ejection after coagulation of hot melt state being formed the shower nozzle of the bead of millimeter magnitude.
Background technology
The moulding process of spheric granules generally adopts the material of shower nozzle ejection molten condition, material is by forming a fine rule behind the spray orifice of shower nozzle, fracture is shrunk to single spheric granules in the freely falling body process under the gravity effect, in the process that falls also is the process of cooled and solidified, promptly becomes solid-state spheric granules before landing.
For making grain forming have controllability, there are some technological means that this is improved, such as shower nozzle moving back and forth at the enterprising line period of direction of material ejection, perhaps shower nozzle is moving back and forth perpendicular to the enterprising line period of direction of material ejection, perhaps shower nozzle carries out the rotation of certain speed, this all makes material be subjected to extra active force when ejection, makes material controlledly be broken for particle.
But above the whole bag of tricks all needs shaped device is carried out extra improvement, and production cost is higher, the device more complicated.And, because the existence of extra active force, speed when causing the spheric granules ejection is inhomogeneous, therefore be easy to bump between the spheric granules, the collision of the particle that does not solidify fully can have influence on the uniformity of grain forming diameter, even a plurality of particles are bonded in together the waste product of generation some.
Summary of the invention
The purpose of this utility model provides the bonding shower nozzle that can not bump after a kind of material ejection that makes the hot melt state.
For achieving the above object, provide following technical scheme.
A kind of shower nozzle, its jet face have middle part resistance gradual change less than around the spray orifice of resistance.
In the flow process of fluid, it is big more to stand resistance, and its speed is slow more.Therefore, it is less that the material of shower nozzle of the present utility model middle part ejection stands resistance, and the speed after the ejection is very fast, so can spray larger distance, and the material of ejection stands bigger resistance around the shower nozzle, and ejection back speed is slower, so can only spray nearer distance.So the material of the spray orifice ejection of different levels has different jet lengths, the particle that the material after the ejection forms can not collide bonding mutually, so have extraordinary molding effect.This sprinkler configuration is simple, and processing cost is low, under the lower situation of tooling cost, has reached best molding effect, and highly efficient in productivity.

The specific embodiment
The accompanying drawings specific embodiment of the present utility model.
As Fig. 1 is the schematic cross-section of shower nozzle 4.4112 thicken than middle part 4111 gradual changes around the described jet face 41.The diameter of spray orifice 413 is all identical, so can form bead of uniform size after the ejection of the material of hot melt state.Have short length near the spray orifice 413 at middle part 4111, so material stands the frictional force of shorter length, so suffered resistance is less, can spray fartherly, shown in Fig. 1 dotted line.
Embodiment 2
As Fig. 2, described jet face 41 has and comprises outer hole 4131 and endoporus 4132 two-part spray orifices 413, the diameter in described outer hole 4131 is all identical, the diameter of described endoporus 4132 is also identical, endoporus 4132 diameters are greater than the diameter in outer hole 4131, near endoporus 4132 degree of depth gradual changes at jet face 41 middle parts 4111 greater than near around the degree of depth of 4112 endoporus 4132.Diameter is big more, and resistance is more little, and the material of the hot melt state bigger endoporus distance of diameter of flowing through near the ejection of the spray orifice at middle part 4111 time is longer, so ejection back speed is faster, the ejection distance is farther.
Embodiment 3
As Fig. 3, described jet face 41 has and comprises outer hole 4131 and endoporus 4132 two-part spray orifices 413, the diameter in described outer hole 4131 is all identical, and endoporus 4132 diameters are greater than outer hole 4131 diameters, jet face 41 middle parts 4111 endoporus, 4132 Diameter Gradual Change greater than around 4112 endoporus, 4132 diameters.Near endoporus 4132 Diameter Gradual Change at jet face 41 middle parts 4111 greater than near around the diameter of 4112 endoporus 4132.Because the hole that diameter is bigger has less resistance, the less hole of diameter has bigger resistance, so less near bigger endoporus 4132 resistances of the diameter at middle part 4111, the material of hot melt state therefrom sprays and stands less resistance, so ejection back speed is faster, the ejection distance is farther.
Described jet face 41 is positioned at shower nozzle 4 outer convex surfaces 411 and is taper seat or sphere.
The concave surface 412 that described jet face 41 is positioned at shower nozzle 4 is taper seat or sphere.
Taper seat processing is easy, and spherical structure is mellow and full, and material fluidity is good.
Fig. 4,4112 spray orifice 413 reduces than the Diameter Gradual Change of the spray orifice 413 at middle part 4111 around the jet face 41.The spray orifice resistance that diameter is bigger is less, so the material speed of ejection is very fast, the material of the spray orifice ejection of different levels can not bump bonding yet.The material that successively sprays from same spray orifice, if spouting velocity is very fast, then successively the distance between the material of ejection can be longer, the distance of drawing back is bigger, so also will be thinner, so can make the material of ejection all around and the material of center ejection form the identical spheric granules of diameter according to the different-diameter size of certain regular well-designed spray orifice.
Embodiment 5
As Fig. 5, the feed head of described shower nozzle 4 is opened the position at jet face 41 middle parts 4111.When fused materials delivers into shower nozzle 4 inside from top to bottom, can increase the flowing velocity of material, save power by gravity.
Certainly, the charging aperture of shower nozzle 4 can also be opened the side at shower nozzle, also can be opened in other positions of jet face, also can be opened in the optional position at the shower nozzle back side, can be for carrying out different designs under the different situations.Simultaneously, can also not offer spray orifice 413 in some position of jet face 41, in order to avoid the solid accumulation of ejection is on charging line at different situations.The described back side refers to another example with respect to jet face.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
