The first function of the gas introduced into the first input hole is responsible for controlling the opening and closing of the sprayer 1 body, the sealant at the opening of the sprayer 1 can be sprayed out through the sprayer 1, and the second function is controlling the spraying speed (air pressure) of the sealant. The second inlet hole is used for controlling the atomization of the sealant entering the spray head 1, and the higher the air pressure value is, the smaller the diameter of the atomized sealant particles is.

The first input hole is connected to the gas compressor 3 (usually an air compressor) through the first gas pipe 21, the second input hole is connected to the gas compressor 3 through the second gas pipe 22, the controller 4 for adjusting the pressure is connected between the first gas pipe 21 and the second gas pipe 22, the controller 4 comprises a first adjusting valve 41 (e.g. SDR200081 manufactured by alder (china) limited) communicated with the first gas pipe 21 and a second adjusting valve 42 (e.g. SDR200081 manufactured by alder (china) limited) communicated with the second gas pipe 22, and the pressure in the first gas pipe 21 and the second gas pipe 22 is adjusted and set by rotating the adjusting knobs on the first adjusting valve 41 and the second adjusting valve 42.

As shown in fig. 2, the feed hole is connected to the pressure barrel 6 through the feed pipe 5, the inner space of the pressure barrel 6 is connected to the gas compressor 3 through the third gas pipe 23, when the gas compressor is in operation, the sealant is left in the pressure barrel 6, and the gas compressor 3 feeds air into the pressure barrel 6, so that the pressure in the pressure barrel 6 is increased, and the sealant is pressed into the spray head 1 through the feed pipe 5.

The pressure barrel 6 comprises a barrel body 61 and a barrel cover 62 detachably connected to the barrel body 61, the air outlet of the third air pipe 23 is fixed at the top end inside the barrel body 61, and the feeding hole of the feeding pipe 5 is fixed at the bottom end inside the barrel body 61. A pressure gauge for detecting the pressure in the barrel is arranged on the barrel cover 62. The transparent liquid volume display tube communicating the upper and lower ends of the tub 61 is installed on the side wall of the tub 61. When the pressure barrel works, the third air pipe 23 injects air into the pressure barrel 6, and materials in the pressure barrel 6 are pressed into the spray head 1 through the feeding pipe 5.

An on-off switch is arranged in the controller 4, and the on-off switch automatically controls the on and off of the first air pipe 21. The on-off switch includes a solenoid valve 43 provided on the air pipe between the first regulating valve 41 and the gas compressor 3, and a PLC controller 44 controlling the on-off of the solenoid valve 43. Immediately before the plate member 8 enters the area of the head 1, a signal sensed to the plate member 8 is transmitted to the PLC controller 44 by means of a wire connection by a sensor 45 (which may be a conventional photoelectric sensor).
