[0021] This embodiment provides an air blowing device for cutting fiberglass mat, aiming to solve the problem of reduced product quality caused by the generation of broken mat fragments after cutting during the weaving process. (See reference...) Figures 1-3The specific structure of this embodiment will be described in detail below.

[0022] An air blowing device for cutting felt fabric includes a support plate 1 mounted on a frame;

[0023] Specifically, the support plate 1 is equipped with multiple first valves 3 via a locking mechanism 2. The air inlet of each of the multiple first valves 3 is connected to the airflow branch pipe 4 via a hose, and the airflow branch pipe 4 is connected to external compressed gas. The air outlet of each of the multiple first valves 3 is equipped with a nozzle.

[0024] In this embodiment, the support plate 1 is mounted on the frame of the felt weaving machine. The felt fabric is driven forward from below the support plate 1. Multiple first valves 3 are installed on the support plate 1 via a locking mechanism 2. The air inlet ends of the multiple first valves 3 are connected to flexible hoses via quick connectors. These hoses are all connected to airflow branch pipes 4, which are connected to external compressed gas. Thus, compressed gas is transmitted to the first valves 3 through the airflow branch pipes 4. Nozzles are installed at the air outlet ends of the first valves 3, and air is blown onto the forward-moving felt fabric through the nozzles.

[0025] Blowing away the felt scraps produced after cutting the felt eliminates the need to process the scraps after rolling up the felt, making the operation simple, saving a lot of manpower and resources, and improving product quality.

[0026] Optionally, the specific number of the first valve 3 can be set according to the actual situation. The first valve 3 can be a gas pipeline straight-through shut-off valve.

[0027] Optionally, external compressed gas can be supplied by an air compressor, with the airflow branch pipe 4 connected to the air compressor outlet.

[0028] Optional nozzles include either fan-shaped blower nozzles or omnidirectional nozzles.

The first valve 3 is installed in the through hole, with the outlet end of the first valve 3 facing downwards to facilitate the installation of the nozzle, and the inlet end of the first valve 3 facing upwards to facilitate communication with the airflow branch pipe 4 through the hose.

[0037] Optionally, a flange is provided on the outer surface of one end of the valve body of the first valve 3. The first valve 3 is placed in the top through hole of the mounting plate 25 and fixed by bolts passing through the flange and mounting plate 25 and engaging with nuts.

[0038] Optionally, an external thread is provided on the outer surface of one end of the valve body of the first valve 3, and two locking nuts are fitted on the external thread. The first valve 3 is placed in the top through hole of the mounting plate 25 and is clamped on both sides of the mounting plate 25 by the two locking nuts, thus fixing the first valve 3 on the mounting plate 25.

[0039] Alternatively, the first valve 3 can be placed in the top through hole of the mounting plate 25 and directly welded in place.

[0040] Specifically, the support plate 1 has two limiting plates 12 installed on the frame at both ends. The end of the support plate 1 is clamped between the two limiting plates 12. The limiting plates 12 and the support plate 1 have through holes. A pin 13 is inserted into the through hole, so that the support plate 1 can be movably installed on the frame.
