The coating thickness is uneven in areas far from the nozzle, which affects the flame retardant effect of the finished polyester fabric.

[0005] Therefore, we propose a flame-retardant polyester fabric surface coating spraying equipment. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0019] 1. This utility model, by setting up a spraying assembly, allows the spraying machine to be started during spraying. The paint is transported through a three-way pipe to two guide pipes, and then from the two guide pipes to two nozzles. The paint is then sprayed from the nozzles onto the surface of the polyester fabric. At the same time, the motor is started to drive the bidirectional screw to rotate, causing the bidirectional screw to drive the two connecting seats to move relative to or opposite to each other along the guide rod. This causes the connecting seats to drive the nozzles to move back and forth within the support frame, thereby uniformly spraying the surface of the polyester fabric, making the coating thickness of the polyester fabric uniform, and improving the flame retardant effect of the finished polyester fabric.

[0020] 2. This utility model, by setting a driving component, can activate the cylinder to extend and retract, causing the piston end of the cylinder to drive the connecting plate to rise and fall, and the connecting plate to drive the support frame to rise and fall, thereby facilitating the adjustment of the nozzle height. When the nozzle height changes, the size of the cone-shaped range of the paint sprayed onto the polyester fabric surface will change, but since the amount of paint sprayed from the nozzle per unit time remains constant, the thickness of the paint sprayed onto the polyester fabric surface will change, making it easy to control the coating thickness.

[0021] 3. By setting up a drying component, this utility model can start a fan to blow air into the outer casing and blow air through the air outlet onto the surface of the sprayed polyester fabric to quickly dry the coating. Attached Figure Description

[0032] This utility model provides a technical solution:

[0033] Please see Figures 1-4 A flame-retardant polyester fabric surface coating spraying device includes a workbench 1, a spraying box 2, a spraying component 3, and a drying component 4. An unwinding shaft 11 and a rewinding shaft 12 are rotatably mounted on both sides of the workbench 1. The spraying component 3 and the drying component 4 are sequentially arranged inside the spraying box 2. Both sides of the spraying box 2 have feed ports 21. By setting up the workbench 1, the spraying box 2, the spraying component 3, and the drying component 4, one end of the polyester fabric can be pulled off from the unwinding shaft 11, and the polyester fabric can be introduced into the spraying box 2 along the feed ports 21. Finally, the rewinding shaft 12 is used to rewind the sprayed polyester fabric, allowing the polyester fabric to move within the spraying box 2. The spraying component 3 sprays the polyester fabric, and the drying component 4 dries the sprayed coating.

[0034] Specifically, the spraying assembly 3 includes a sprayer 31 mounted on top of the spraying box 2 and a support frame 32 mounted inside the spraying box 2. A three-way pipe 33 is fixedly connected to the outlet end of the sprayer 31, and guide pipes 34 are fixedly connected to both ends of the three-way pipe 33. The guide pipes 34 are flexible corrugated hoses, and a nozzle 35 is fixedly connected to the end of the guide pipes 34. A bidirectional screw 36 is rotatably mounted inside the support frame 32. A motor 37 for driving the bidirectional screw 36 is fixedly mounted on one side of the support frame 32. Two symmetrically distributed connecting seats 38 are threaded onto the bidirectional screw 36, and the nozzle 35 is fixedly mounted on the connecting seats 38. A motor 37 for driving the bidirectional screw 36 is fixedly mounted inside the support frame 32. The guide rods 310 are arranged in parallel, and the connecting seats 38 are slidably sleeved on the guide rods 310. By setting the spraying assembly 3, during spraying, the spraying machine 31 can be started to transport the paint through the three-way pipe 33 to the two guide pipes 34, and then from the two guide pipes 34 to the two nozzles 35 respectively. The paint is sprayed from the nozzles 35 onto the surface of the polyester fabric. At the same time, the motor 37 is started to drive the bidirectional screw 36 to rotate, so that the bidirectional screw 36 drives the two connecting seats 38 to move relative to or opposite to each other along the guide rods 310, so that the connecting seats 38 drive the nozzles 35 to move back and forth within the support frame 32, thereby uniformly spraying the surface of the polyester fabric, making the coating thickness of the polyester fabric surface uniform, and improving the flame retardant effect of the finished polyester fabric.

[0035] The top of the spray box 2 is equipped with a drive component 39 for driving the support frame 32 to rise and fall. The drive component 39 includes a cylinder 391 fixedly installed on the top of the spray box 2. The cylinder 391 is vertically arranged on the spray box 2. The piston end of the cylinder 391 is fixedly connected to a connecting plate 392. The connecting plate 392 is fixedly connected to both sides of the support frame 32. By setting the drive component 39, the cylinder 391 can be activated to extend and retract, so that the piston end of the cylinder 391 drives the connecting plate 392 to rise and fall, and the connecting plate 392 drives the support frame 32 to rise and fall. This makes it easy to adjust the height of the nozzle 35. When the height of the nozzle 35 changes, the size of the cone-shaped range of the paint sprayed by the nozzle 35 onto the surface of the polyester fabric will change. However, since the amount of paint sprayed from the nozzle 35 per unit time remains unchanged, the thickness of the paint sprayed by the nozzle 35 onto the surface of the polyester fabric changes, which makes it easy to control the coating thickness.

[0036] Specifically, the drying component 4 includes a housing 41 fixedly installed on the top of the spray box 2. A fan 42 is installed on the top of the housing 41, with the outlet of the fan 42 facing the same direction. Several evenly distributed air outlets 43 are opened at the bottom of the housing 41. By setting the drying component 4, the fan 42 can be started to blow air into the housing 41 and blow air through the air outlets 43 onto the surface of the sprayed polyester fabric to quickly dry the coating.

[0037] A filter screen 44 is fixedly installed on the top of the outer casing 41 above the fan 42. By setting the filter screen 44, impurities can be prevented from entering the fan 42.

[0038] In practical use, the working principle of this utility model is as follows:

[0039] First, one end of the polyester fabric can be pulled off the unwinding shaft 11 and introduced into the spraying box 2 along the feed port 21. Finally, the rewinding shaft 12 is used to rewind the sprayed polyester fabric, so that the polyester fabric moves in the spraying box 2. The spraying component 3 sprays the polyester fabric, and the drying component 4 dries the sprayed coating.

[0040] During spraying, the cylinder 391 can be activated to extend and retract, causing the piston end of the cylinder 391 to drive the connecting plate 392 to rise and fall, which in turn causes the connecting plate 392 to drive the support frame 32 to rise and fall, thus adjusting the nozzle 35 to a suitable height.

[0041] Then, the spraying machine 31 can be started to transport the paint through the three-way pipe 33 to the two guide pipes 34, and then from the two guide pipes 34 to the two nozzles 35 respectively, and sprayed from the nozzles 35 onto the surface of the polyester fabric.

[0042] At the same time, the start motor 37 drives the bidirectional screw 36 to rotate, causing the bidirectional screw 36 to drive the two connecting seats 38 to move relative to or opposite to each other along the guide rod 310, causing the connecting seats 38 to drive the spray head 35 to move back and forth within the support frame 32, thereby uniformly spraying the surface of the polyester fabric and making the coating thickness of the polyester fabric surface uniform.

[0043] The blower 42 can be activated to blow air into the housing 41 and blow air through the air outlet 43 onto the surface of the coated polyester fabric to quickly dry the coating.

[0044] In summary, this flame-retardant polyester fabric surface coating spraying equipment, by setting up the spraying component 3, allows the spraying machine 31 to be started during spraying. The coating is transported through the three-way pipe 33 to two guide pipes 34, and then from the two guide pipes 34 to two nozzles 35, which spray onto the surface of the polyester fabric. At the same time, the motor 37 is started to drive the bidirectional screw 36 to rotate, causing the bidirectional screw 36 to drive the two connecting seats 38 to move relative to or in opposite directions along the guide rod 310. This causes the connecting seats 38 to drive the nozzles 35 to move back and forth within the support frame 32, thereby uniformly spraying the surface of the polyester fabric, making the coating thickness uniform, and improving the flame-retardant effect of the finished polyester fabric.

[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
