Description
Technical field
The present invention relates to a kind of extrusion coated head, especially suitable for being installed and used on coating machine.
Background technology
Existing coater head includes liquid storage cylinder and upper lid, 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,
Its shortcoming is due to that 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, there are corner angle, being capped on the liquid storage cylinder of head has upper lid
And be bolted, during if desired for cleaning liquid storage cylinder, bolt need to be pulled down, upper lid is removed from liquid storage cylinder, when 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 present invention is to provide a kind of section cavities designed according to fluid mechanics principle, easy to clean, coating
Uniformly, the amount of liquid storage in liquid storage cylinder is big, and liquid laterally sprawls uniform slit extrusion coated head.
The task of the present invention, which is done in such a way that, is characterized in that：Coater head is fixed in frame against applicator roll, is applied
Cloth head includes upper lid and liquid storage cylinder, and the upper lid and liquid storage cylinder are to be flexibly connected, its both ends of the top surface flat smooth of upper lid peace
Equipped with foam-discharging valve, the foam-discharging valve valve body is provided with blast pipe, and blast pipe, through liquid storage cylinder is fallen into, is arranged in the hole of upper lid processing
Rotary handle is installed on bubble valve, the front of the upper lid is provided with lock, and it is not plane that, which there is the gradient at the back side of upper lid, upper lid two
The shape of side end face is the triangle of a unfilled corner, and the shape of the liquid storage cylinder matches with upper lid and snapped together, liquid storage cylinder
On the dop of locking lock corresponding with upper lid is installed, inlet is installed, in liquid storage cylinder at the center of the face view of liquid storage cylinder
Cavity be longitudinal direction half droplet-shaped variable cross-section, horizontal clothes hanger type variable cross-section.The outer shape of the upper lid and liquid storage cylinder is in clothes hanger shape,
There is no corner angle on round and smooth transition face.The diameter of the inlet is more than the diameter of inlet outlet.
The present invention 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, coating fluid
Buffering flowing does not produce bubble, laterally sprawls uniformly, ensures product quality, the generation of waste product is reduced, so as to improve the warp of enterprise
Ji benefit.
Brief description of the drawings
The structure that Fig. 1 is the present invention watches master map attentively；Fig. 2 is Fig. 1 top view；Fig. 3 is Fig. 2 side view.
Drawing explanation：1st, coater head, 2, upper lid, 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 provided with corner angle, upper lid can open, and overcome
The shortcoming that can not be opened is covered in prior art, and the upper lid 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 frame against applicator roll, coater head 1 includes upper lid
With liquid storage cylinder 6, the upper lid and liquid storage cylinder are to be flexibly connected, and upper lid 2 can be opened, the outer shape of the upper lid 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 lid are provided with foam-discharging valve
3, the foam-discharging valve valve body is provided with blast pipe, and blast pipe, through liquid storage cylinder is fallen into, is pacified in the hole of upper lid processing on foam-discharging valve
Equipped with rotary handle, the opening and closing of foam-discharging valve is controlled by rotary handle, due to being provided with blast 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 lid is provided with lock, and the back side of upper lid has the gradient not to be
Plane, the shape of upper lid both sides end face is the triangle of a unfilled corner.
The shape of the liquid storage cylinder is matched with upper lid and snapped together, and locking lock corresponding with upper lid is provided with liquid storage cylinder
5 dop is detained, inlet 4 is installed at the center of the face view of liquid storage cylinder, the diameter of the inlet exports 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 covered in time, bubble is arranged
Go out, reduce the generation of waste product, when such as cleaning liquid storage cylinder after the certain time that works, need to only open the card on liquid storage cylinder main-vision surface
Lock on head and upper lid, upper lid just can be opened, easy to clean, quick, so as to improve final product quality.
