Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figure 1, the cutter clutch mechanism of the flat sewing machine with the cutter comprises a shell 1, a cutter component 2, a cutter driving component and a clutch power component 3. The cutter driving assembly comprises a motor, an upper shaft and a side shaft, the upper shaft and the side shaft are positioned in the machine shell 1, the upper shaft is driven by the motor to rotate relative to the machine shell 1, the side shaft and the upper shaft are connected through a cam, and the upper shaft drives the side shaft to synchronously rotate. The side wall of the casing 1 is provided with a first mounting seat 11, and one end of the side shaft is positioned in the first mounting seat 11.

In the above technical scheme: the cutter assembly 2 comprises a transmission shaft 21, a transmission block 22, a spring sheet 23, a connecting rod 24 and a cutter. The end of the side shaft passes through the first mounting 11 and is connected to the transmission block 22. The end of the spring plate 23 is fixed with the transmission block 22. The end of the connecting rod 24 is provided with a screw, the head of the screw forms a clamping block 26, the rod part of the screw penetrates through the elastic sheet 23 and the connecting rod 24 and is sleeved with a nut 25, and therefore the elastic sheet 23 is connected with the screw and the connecting rod 25. The middle part of the connecting rod 24 is hinged with the transmission block 22. The bottom of the machine shell 1 is provided with a second mounting seat 12, the bottom of the transmission shaft 21 is positioned in the second mounting seat 12, and the cutter is arranged at the bottom end of the transmission shaft 21. The top of the driving shaft 21 passes through the top of the cabinet 1 and is formed with a handle 211. The transmission shaft 21 is provided with a connecting block 27, and the connecting block 27 is provided with a clamping groove 271. The transmission shaft 21 is further sleeved with a material cutting spring 28, and two ends of the material cutting spring 28 are respectively in contact with the bottom of the connecting block 27 and the second mounting seat 12.

When cloth needs to be cut, the clamping block 26 is located in the clamping groove 271, the cutter driving assembly is connected with the cutter assembly 2, the cutter is located below the second mounting seat 12, and the cutter driving assembly drives the cutter to reciprocate up and down to complete cutting. The motor drives the upper shaft, the side shaft and the transmission block 22 to rotate, the fixture block 26 is driven to move downwards, and therefore the fixture block 26 drives the connecting block 27, the transmission shaft 21 and the cutter to move downwards, and material cutting is completed. The blanking spring 28 is compressed during the above process. After the material cutting is finished, the motor drives the upper shaft, the side shaft and the transmission block 22 to rotate reversely, the fixture block 26 drives the connecting block 27, the transmission shaft 21 and the cutter to move upwards and reset, and the elastic part of the material cutting spring 28 releases the reset of the auxiliary cutter.

In the above technical scheme: the clamping block 26 and the clutch power assembly 3 are respectively positioned at two sides of the transmission block 22. The connecting rod 24 forms a lever with the transmission block 22 as a fulcrum. The clutch power assembly 3 comprises an electromagnet 31, a transmission magnet 32 and a clutch spring 33. The electromagnet 31 is installed on the side of the machine case 1 through the bracket 34, the transmission magnet 32 is installed on the bracket 34 in a sliding manner, and the clutch spring 33 is installed on the transmission magnet 32 in a sleeving manner and moves synchronously with the transmission magnet 32. The end of the connecting rod 24 remote from the latch 26 is hinged to the driving magnet 32 by a mounting block 35.

When the electromagnet 31 is energized, magnetism is generated to attract the transmission magnet 32 to move, and the end of the clutch spring 33 contacts the outer wall of the electromagnet 31 to compress the clutch spring 33.
