New description: [New technical field] This creation relates to a device for sucking dust from a sewing machine, especially a sewing machine suction control valve group with a silent function and concentrated suction. [Prior Art] A device with a slitting machine for sucking dust, such as the new patent case No. 3452〇7, “The device for scraping the cloth guides”, which is installed in the sewing machine. At the air outlet, and including a trough body, the trough body has a conduit extending downwardly from the end, and the first conduit is provided with a first guide port, and the first guide port of the stomach is provided with a second guide port. The second guide port is connected to the outlet password of a nozzle. The outer edge of the nozzle is provided with _π, and the thread is provided on the peripheral wall of a ring groove. The sleeve is closed, and the suction end of the nozzle is exposed outside the sleeve, and a sleeve is arranged on the sleeve. When the device is installed, the child presses the second pressure body from the joint into the air outlet end of the nozzle through the plurality of teeth, ^ π ^ . Forms a strong wind blowing toward the catheter, and the sewing is cut. The cloth scraps are automatically supplied by the tank, and the gas is sent out to the collecting device by the gas. However, since the above nozzle directly blows a strong wind into the duct, the high-frequency wind-cutting sound is emitted at the junction, the ear is turned into a ringing noise, and since the limb is set at a distance from the disc discharge point, the society + I The effect of forming and removing the swarf is not good, and the shape of the mouthpiece has a plurality of bulges and a plurality of through-holes make the production difficult, and the processing cost is high and it is not easy to manufacture. In order to improve the sewing machine's suction device, please refer to the publication No. 4 M286844 380643, "Chongke car cloth is pumping. To be a silent tube for improving air jets," the new patent case, the main shoulder pumping Suction device ±, the mute total wind cut, the sound 'it is installed on the plane of the copy car'.

The air inlet screw hole 4) is provided with an inner side of the air inlet and the air chamber hole (3 1 4 10 4 M286844 and the connecting tube member (3 5 ) is a round tube body at the rear end, and the front end corresponds to the cone hole. On the tapered surface of the tapered hole (") (3 5 !)

The suction adjustment control device (40) includes a pipe fitting " a = adjusting control read (4... wherein the pipe # (41) is the end sleeve, and the (3 0 ) is connected to the pipe fitting portion (3 5 )) And the suction adjustment control valve (4 〇) is provided in the middle of the pipe (4 1) > to control the amount of intake air sucked by the other end. Please cooperate with the one, four, five, and seven pictures. The original design is worn on the seam cutting machine (50), with the joint of the fixed frame (15), 1) combined with the seam rush machine (5座) the seat plate and the suction device (the δδ is at the corresponding sewing device (5 1 ), and the opening of the suction head (the hood part (1, , 匕i) is aligned with the sewing device (5 1) Produce a cloth genus' and the air outlet (1 i 2) of the tee pipe (1 1 ) is connected to the pipe branch - a collecting device "0" for collecting cloth dust, the jet crack, 〇 7 M286844 ( 3 Ο ) is fixed at one place under the seat plate of the sewing machine (5 Ο ), and an adjusting joint (5 2 1 ) is screwed with the air inlet screw hole (3 4 ) and then connected to a high pressure air pipe (5 2) to be inward. Introducing high-pressure air. When the high-pressure gas is introduced inwardly from the high-pressure gas pipe (52), the gas is injected into the gas chamber hole (3 1 4) and the flow velocity is accelerated through the small orifices (3 3 ). Flowing toward the gas injection hole (3 1 3 ), the high pressure gas is ejected from the gas injection hole (3 1 3 ) into the muffler (20), and is generated between the gas injection hole (3 1 3 ) and the suction hole (3 5 5 ) Vacuum suction Force ginseng, therefore, will be supplemented by suction at the suction adjustment control device (4 ◦), and the device can be adjusted by the suction adjustment control valve (42) to control the airflow size; when the high pressure gas passes through the silencer ( 2〇), since the tube body (2 1 ) of the muffler (20) has a large diameter and a circular arc wall surface, the flow rate of the gas passing therethrough is slowed and flows smoothly, and the noise volume can be effectively reduced, and The diameter of the inlet pipe (22) and the outlet pipe (23) are smaller than the pipe body (2 1 ), so it does not affect the flow rate of the gas. ® When the gas is taken from the gas outlet pipe (23) toward the tee pipe When the air outlet (1 1 2) of (11) is sprayed, vacuum attraction is generated at the hood portion (1 2 1 ) of the suction head (1 2 ), and the cloth is concentrated by the hood portion (1 21). Chips, the cloth dust and gas are brought into the tee pipe (1 1), and the air outlet (1 1 2) is sent to the collecting device (60) for collecting the cloth dust to store the cloth dust. • [Simple description] The first picture is a perspective view of the creation.
