The pipe 9 passes through a hole 2 at the end away from the spiral supercharged suction device 8 and is fixedly connected to the cutter head 4. The pipe 9 is communicated with the interior of the cutter head 4. An electric control box 10 is fixedly connected to the right side of the lower surface of the desktop of the sewing machine table 1. This suction thread trimmer uses a 12V / 20W brushless motor, and the electric control box 10 controls the cutter head 4 and the spiral supercharged suction device 8 through a cable connection.

[0023] The fixing seat 3 includes a caliper seat 301, which is U-shaped. The caliper seat 301 is clamped on the front side of the desktop of the sewing machine table 1. The lower surface of the caliper seat 301 is threadedly connected with an adjusting screw 302. The upper end of the adjusting screw 302 is squeezed on the lower surface of the desktop of the sewing machine table 1. The upper surface of the caliper seat 301 is fixedly connected with a connecting column 303. The upper end of the connecting column 303 is rotatably connected to a seat bracket 304 through a bearing. The upper end of bracket 1 304 is convex, and a base bracket 2 305 is provided on the side of base bracket 1 304 away from connecting column 303. The lower end of base bracket 2 305 is concave, and the lower end of base bracket 2 305 is clamped on the upper end of base bracket 1 304. An adjusting screw 2 306 is provided at the connection between base bracket 2 305 and base bracket 1 304, and the adjusting screw 2 306 is threadedly connected to base bracket 1 304 and base bracket 2 305.

[0024] The second card holder bracket 305 is fixedly connected to the first card holder 307 at the end away from the first card holder bracket 304, and the left side of the card holder 307 is movably connected to the second card holder 308 via a hinge. The second card holder 308 is symmetrical to the first card holder 307, and the right ends of the first card holder 307 and the second card holder 308 are commonly connected with a buckle 309, which fixes the first card holder 307 and the second card holder 308 together.

[0025] The first and second card holders 307 and 308 are connected to the cutter head 4, and the cutter head 4 is embedded with an electric eye 5. The electric eye 5 is a miniature latest induction electric eye (photoelectric type), with an induction distance of 0-5mm and a response time of 0.5 seconds, which can sense fabrics of all colors; the latest DC brushless motor is used in the cutter head 4, which has a long service life, low noise and is not easy to be damaged; the moving blade of the cutter head 4 is made of ceramic material, which is not easy to wear. When the thread of the clothing fabric approaches the electric eye 5 of the thread cutting blade, the spiral supercharged suction of the spiral supercharged suction device 8 immediately generates suction, and at the same time, the motor of the cutter head 4 starts immediately, and the thread is sucked into the cloth bag at the moment of cutting; when the clothing fabric with the thread cut leaves the electric eye 5 of the thread cutting blade, the spiral supercharged suction of the spiral supercharged suction device 8 and the motor of the cutter head stop immediately; at the same time, it can also stop working after a set delay time, and the delay time is set by the adjustable knob on the panel (0-15 seconds can be selected).

[0026] A protective head 6 is provided on the front surface of the cutter head 4, and the protective head 6 includes a head plate 601, which is clamped on the cutter head 4. The front surface of the head plate 601 is evenly and equidistantly embedded with embedded columns 602, and the number of the embedded columns 602 is three. Holes 603 are evenly and equidistantly opened on the surfaces of the three embedded columns 602, and four holes 603 are opened on each embedded column 602, and the four holes 603 are interconnected.

[0027] The outer edge of each second hole 603 is rotatably connected to a protective arc plate 604 via a torsion spring. The protective arc plate 604 is in a smooth round cake shape and is adapted to the second hole 603. In the initial state, the protective arc plate 604 is tilted in front of the second hole 603.

[0028] Working principle:

[0029] The first step: by clamping the clamping seat 1 307 and the clamping seat 2 308, the cutter head 4 can be fixed on the fixing seat 3 or held by hand by opening or closing the buckle 309. The use mode of the cutter head 4 can be changed according to the needs of the person, so that the suction wire trimmer can be used flexibly.

[0030] Step 2: Through the movable connection between the base bracket 1 304 and the connecting column 303, and the threaded connection between the base bracket 2 305 and the base bracket 1 304 through the adjusting screw 2 306, the fixing base 3 can be loosened as needed, and the cutter head 4 clamped by the base 1 307 and the base 2 308 can be adjusted up and down and left and right.

[0031] Step 3: The spiral booster suction device 8 replaces the traditional electric suction motor, uses a vacuum generator to suck air, and uses compressed air to inject. The positive source air pressure produces negative pressure in the vacuum device, forming a vacuum-like interval, thereby generating a strong suction force, achieving the function of the blade instantly sucking up the thread end and cutting it, making the suction thread shearing machine absorb the thread end quickly and accurately.

[0032] Step 4: This product is small in size and easy to use; it uses a 12V / 20W brushless motor, which is energy-saving and environmentally friendly; because the spiral supercharged suction device 8 is equipped with a spiral supercharged suction, it can instantly start the suction function, with high efficiency and no noise, achieving the effect that can only be achieved by long-term suction with motors on the market, reducing 98% of the noise generated by ineffective work, using 2% of the effective working time, and no longer needing a 220V / 400W fan, so that energy saving can reach more than 95%.

[0033] Step 5: This spiral pressurized suction thread trimmer is very convenient to use with a sewing machine. It can be used independently in the sewing process in the sewing factory that requires this workstation. The thread trimming process can be completed in the front, middle and back sections of sewing. The thread trimming is clean, energy-saving and environmentally friendly, and has good effects. It focuses on solving the problem of manual thread trimming in garment factories.

[0034] Step 6: Through the design of the protective head 6 and the spiral booster suction of the spiral booster suction device 8, when the spiral booster suction device 8 is sucking air, the thread ends will pass through the second hole 603 and the pipe 9 into the cloth bag 7 to be collected. At the same time, the protective arc plate 604 arranged on the second hole 603 will also be absorbed by the wind and gradually closed on the second hole 603, ensuring that the surface of the clothing except for the thread ends will not be absorbed by the blade and cut, thereby ensuring the safety of the use of the device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
