Abstract

An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly ( 28 ) that includes a nozzle having a nozzle head ( 108 ). The nozzle assembly ( 28 ) also includes a baffle plate ( 101 ) including a cutout ( 144 ) that extends through the baffle plate ( 101 ), where the baffle plate ( 101 ) is received by the nozzle head ( 108 ) such that the nozzle head ( 108 ) and the baffle plate ( 101 ) define a cavity. The nozzle assembly ( 28 ) further includes a cover plate ( 102 ) attached to the nozzle head ( 108 ) such that the cover plate ( 102 ) secures the baffle plate ( 101 ) within the nozzle head ( 128 ), where an outlet passage is defined between the baffle plate ( 101 ) and the cover plate ( 102 ), the outlet passage being fluidly connected to the cavity through the cutout ( 144 ) of the baffle plate ( 101 ).

First claim

What is claimed:

1. A nozzle assembly for dispensing a material, the nozzle assembly comprising:
a nozzle including a nozzle head, the nozzle head having a body that includes a side surface and a nozzle recess extending into the body from the side surface;
an arm extending downwards along a direction that is angularly offset from a vertical direction, the arm having an inlet and an outlet with a passageway therebetween, and the nozzle head is attached to the arm opposite an upper flange and the nozzle head being connected to the outlet;
a baffle plate including a cutout that extends through the baffle plate, wherein the baffle plate is received in the nozzle recess such that the nozzle head and the baffle plate define a cavity; and
a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle recess, wherein an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate.

2. The nozzle assembly of claim 1 , wherein the baffle plate has an upper surface, a lower surface opposite the upper surface along a vertical direction, a front surface, and a rear surface opposite the front surface along a longitudinal direction that is perpendicular to the vertical direction, wherein the cutout extends 1) into the baffle plate from the upper surface and 2) from the front surface to the rear surface.

3. The nozzle assembly of claim 2 , wherein the front surface of the baffle plate is substantially coplanar with the side surface of the nozzle head when the baffle plate is received in the nozzle recess.

4. The nozzle assembly of claim 2 , wherein the baffle plate has first and second cutout surfaces that extend from the upper surface along the vertical direction, and a third cutout surface that extends from the first cutout surface to the second cutout surface, such that the first, second, and third cutout surfaces define the cutout.

5. The nozzle assembly of claim 4 , wherein the third cutout surface is positioned between the upper and lower surfaces along the vertical direction.

6. The nozzle assembly of claim 4 , wherein the third cutout surface is substantially parallel to the lower surface.

7. The nozzle assembly of claim 1 , wherein the nozzle recess has a first height measured along a vertical direction and the cavity has a second height measured along the vertical direction, wherein the first height is greater than the second height.

8. A nozzle assembly for dispensing a material, the nozzle assembly comprising:
a nozzle including a nozzle head, the nozzle head having a body that includes a side surface and a nozzle recess extending into the body from the side surface;
an arm extending downwards along a direction that is angularly offset from a vertical direction and the nozzle head is attached to the arm opposite an upper flange;
a baffle plate including a cutout that extends through the baffle plate, wherein the baffle plate is received in the nozzle recess such that the nozzle head and the baffle plate define a cavity;
a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle recess, wherein an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate;
the upper flange having an inlet for receiving the material; and
the arm extending from the upper flange to the nozzle head, the arm defining a passage in fluid communication with the inlet and the cavity.

9. The nozzle assembly of claim 8 , further comprising a check valve partially disposed in the passage of the arm.

10. A nozzle assembly for dispensing a material, the nozzle assembly comprising:
a nozzle including a nozzle head, the nozzle head having a body that includes a side surface and a nozzle recess extending into the body from the side surface;
an arm extending downwards along a direction that is angularly offset from a vertical direction and the nozzle head is attached to the arm opposite an upper flange;
a baffle plate including a cutout that extends through the baffle plate, wherein the baffle plate is received in the nozzle recess such that the nozzle head and the baffle plate define a cavity; and
a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle recess, wherein an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate,
wherein the cover plate defines a front surface, a rear surface opposite the front surface along a longitudinal direction, and an outlet recess that extends into the cover plate from the rear surface, wherein the outlet recess at least partially defines the outlet passage.

11. The nozzle assembly of claim 1 , wherein the cover plate includes a first extension that extends downward in a vertical direction from the cover plate adjacent an outlet of the nozzle assembly.

12. The nozzle assembly of claim 11 , wherein the nozzle head includes a second extension that extends downward along the vertical direction adjacent the outlet.

13. The nozzle assembly of claim 1 , wherein the baffle plate comprises an aluminum alloy.

14. A nozzle assembly for dispensing a material, the nozzle assembly comprising:
a nozzle including a nozzle head, the nozzle head having a body that includes a side surface and a nozzle recess extending into the body from the side surface;
an arm extending downwards along a direction that is angularly offset from a vertical direction and the nozzle head is attached to the arm opposite an upper flange;
a baffle plate including a cutout that extends through the baffle plate, wherein the baffle plate is received in the nozzle recess such that the nozzle head and the baffle plate define a cavity; and
a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle recess, wherein an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate,
wherein the baffle plate includes a flange extending into the cavity.

15. The nozzle assembly of claim 1 , wherein the nozzle head includes a plurality of laterally aligned channels that extend from a transfer passage defined by the nozzle head to the cavity.

16. The nozzle assembly of claim 1 , wherein the baffle plate has an upper surface, a lower surface opposite the upper surface along a vertical direction, a front surface, and a rear surface opposite the front surface along a longitudinal direction that is perpendicular to the vertical direction, wherein the cutout extends from the front surface to the rear surface between the upper and lower surfaces.
