Description
Technical field
A kind of extrusion coated head is the utility model is related to, especially suitable for being installed and used on coating machine.
Background technology
Existing coater head includes liquid storage cylinder and upper cover, and the shape of liquid storage cylinder is in inverted trapezoidal or semicircle, coating fluid
Quickly being flowed by liquid outlet in the PET base material being sticked and coated on above applicator roll, this type of flow is not optimal embodiment,
The drawback is that since cavity body structure defect causes to be unevenly coated, and the coating gage distortion produced, so as to influence product
Quality, furthermore, the existing linear property in coater head transverse direction cavity half section, has corner angle, being capped on the liquid storage cylinder of head has upper cover
And be bolted, during if desired for cleaning liquid storage cylinder, bolt need to be pulled down, upper cover is removed from liquid storage cylinder, first, trouble, two
It is that efficiency is low, third, in displacement, the head with corner angle easily scratches operating personnel, fourth, dismounting carries on to carry off and easily causes to apply
The leftover of bolt of cloth deforms.
The content of the invention
The task of the utility model is to provide a kind of section cavities designed according to fluid mechanics principle, easy to clean,
Coating is uniform, and the amount of liquid storage in liquid storage cylinder is big, and liquid laterally sprawls uniform slit extrusion coated head.
The task of the utility model, which is done in such a way that, is characterized in that：Coater head is fixed on rack against applicator roll
On, coater head includes upper cover and liquid storage cylinder, and the upper cover and liquid storage cylinder are to be flexibly connected, the top surface flat smooth of upper cover its two
End is provided with foam-discharging valve, and the foam-discharging valve valve body is provided with exhaust pipe, and exhaust pipe passes through in the hole that upper cover is processed and falls into liquid storage
Chamber, is provided with rotation handle on foam-discharging valve, and the front of the upper cover is provided with lock, and it is not plane that, which there is the gradient at the back side of upper cover,
The shape of upper cover both sides of the face is the triangle of a unfilled corner, and the shape of the liquid storage cylinder matches with upper cover to be snapped together,
The clamp of locking lock corresponding with upper cover is installed on liquid storage cylinder, inlet is installed at the center of the face view of liquid storage cylinder, is stored up
Sap cavity inner chamber body be longitudinal direction half droplet-shaped variable cross-section, horizontal clothes hanger type variable cross-section.The diameter of the inlet goes out more than inlet
The diameter of mouth.
The utility model has the following effects that：The two-way variable cross-section of coater head that the technical program is related to is easy to clean, applies
The buffering flowing of cloth liquid does not produce bubble, laterally sprawls uniformly, ensures product quality, the generation of waste product is reduced, so as to improve enterprise
Economic benefit.
Brief description of the drawings
Fig. 1 is that the structure of the utility model watches master map attentively；Fig. 2 is the top view of Fig. 1；Fig. 3 is the side view of Fig. 2.
Drawing explanation：1st, coater head, 2, upper cover, 3, foam-discharging valve, 4, inlet, 5, lock, 6, liquid storage cylinder, 7, go out liquid
Mouthful.
Embodiment
The coater head cavity variable cross-section that the technical program is related to is in clothes rack shape, and equipped with corner angle, upper cover can open, and overcome
The shortcoming that prior art upper cover cannot be opened, and the upper cover of head leads to liquid storage cylinder and is provided with foam-discharging valve, prevent bubble
Produce, improve the quality of coating, increase the storage capacity of liquid storage cylinder, liquid stabilising can be made, buffering flowing is by half droplet-shaped longitudinal direction side
To variable cross-section, liquid can be made to be spread along vertical and horizontal Quick uniform, so as to reach micron-sized thickness effect, ensure coating
Thickness and good product it is apparent.
For specific embodiment as shown in Figure 1, coater head 1 is fixed in rack against applicator roll, coater head 1 includes upper cover
With liquid storage cylinder 6, the upper cover and liquid storage cylinder are to be flexibly connected, and upper cover 2 can be opened, the outer shape of the upper cover and liquid storage cylinder
In variable cross-section clothes hanger shape type, there is no corner angle on round and smooth transition face, its both ends of the top surface flat smooth of upper cover are provided with foam-discharging valve
3, the foam-discharging valve valve body is provided with exhaust pipe, and exhaust pipe, through liquid storage cylinder is fallen into, is pacified in the hole that upper cover is processed on foam-discharging valve
Equipped with rotation handle, by the opening and closing of rotation handle control foam-discharging valve, due to being provided with exhaust pipe in liquid storage cylinder, therefore in coating fluid such as
It can be discharged in time by air bleeding valve after there is bubble.The front of the upper cover is provided with lock, and the back side of upper cover has the gradient not to be
Plane, the shape of upper cover both sides of the face are the triangles of a unfilled corner.
The shape of the liquid storage cylinder matches with upper cover to be snapped together, and locking lock corresponding with upper cover is provided with liquid storage cylinder
5 clamp is detained, inlet 4 is installed at the center of the face view of liquid storage cylinder, the diameter of the inlet is exported more than inlet
Diameter, effectively mixed liquor can be controlled to slowly enter liquid storage cylinder, avoid producing bubble, the inside of the liquid storage cylinder as shown in Fig. 2,
The longitudinal direction of liquid storage cylinder inner chamber body is half droplet-shaped, and the purpose for being designed to this half drop shape is in horizontal stroke for coating fluid from import
To uniform drawout, extruded by the liquid outlet 7 of coating head and uniformly spread on base material, solve finished product thickness inequality very well
Shortcoming, liquid storage cylinder inner chamber body are to be designed as half droplet-shaped variable cross-section of longitudinal direction, horizontal clothes hanger type variable cross-section according to fluid mechanics principle
Cavity.
During work, the mixed liquor that upstream is made is entered by the inlet set on liquid storage cylinder, by half droplet-shaped liquid storage cylinder
It is expressed on the base material of operation, when bubble is such as had in coating process, opens the foam-discharging valve of upper cover in time, bubble is arranged
Go out, reduce the generation of waste product, when work will such as clean liquid storage cylinder after a certain period of time, need to only open the clamp on liquid storage cylinder main-vision surface
With the lock on upper lid, upper cover just can be opened, easy to clean, quick, so as to improve final product quality.
