When the device is in use, the operator connects the air circuit to the air source, turns on the vacuum pump 25, and the blowing port 14 starts blowing. At this time, the punching waste is separated from the positioning column 15 and enters the material receiving port 12, and the waste can be sucked into the waste box 26 under the action of the vacuum pump 25.

[0051] The following is a detailed explanation:

[0052] When making a hat, it is necessary to make holes in the fabric, and this device is needed. The air circuit in this device is connected to the air source, and the vacuum pump 25 and the blowing port 14 are turned on. At this time, the blowing port 14 starts to blow air, and the operator steps on the pedal 23, and then the swing seat 24 makes the U-shaped frame 7 rise and compresses the third spring 22, driving the rotating shaft 20 to rise, and the rotating shaft 20 drives the left cam 8 and the right cam 21 to rise, and the two sets of movable pins 10 cooperating with the left cam 8 and the right cam 21 rise, so that the positioning column 15 and the ejector pin 17 rise, thereby driving the movable seat 19 to rise along the direction of the guide rail 191. At this time, the top of the positioning column 15 extends out of the mold base 13 on the second bracket 2.

[0053] At this time, take out the cloth to be punched, and according to the protruding positioning column 15, make the punching position of the cloth coincide with the positioning column 15, and use the pressure ring 4 to compact the cloth. At this time, release the foot pedal 23, and the U-shaped frame 7 is reset under the action of the third spring 22, while driving the positioning column 15 to descend. At this time, the two sets of movable pins 10 are both located at point ① (⑤) in the first groove and the second groove of the left cam 8 and the right cam 21. At this time, continue to turn the hand wheel ③, so that the two sets of movable pins 10 are gradually transferred from point ① (⑤) to point ② in the first groove and the second groove of the left cam 8 and the right cam 21.

[0054] Continue to rotate the handwheel 3 to gradually transfer the movable pin 10 in the first groove of the left cam 8 from point ② to point ③. At this time, the positioning column 15 remains stationary, and the movable pin 10 in the second groove of the right cam 21 gradually transfers from point ② to point ③. The ejector pin 17 extends upward under the action of the second groove to pierce the fabric, thereby fixing the fabric. At this time, it is in state ③. At this time, the protrusion on the right cam 21 touches the microswitch 18, which activates the microswitch 18, and the working shaft of the cylinder 6 begins to extend rapidly, thereby causing the punch 5 to cooperate with the die base 13 to punch the fabric out of the round hole.

[0055] When the punch hole is continued to rotate the hand wheel 3, the two movable pins 10 are gradually transferred from the ③ point to the ④ point in the first groove and the second groove of the left cam 8 and the right cam 21, at this time, the positioning column 15 continues to keep still, the ejector pin 17 is changed from the upward stretching state to the retracted state under the action of the second groove, and the ④ state is shown, in the retracting process of the ejector pin 17, the punch hole waste on the ejector pin 17 is gradually separated from the ejector pin 17 through the positioning column 15, the waste is separated from the positioning column 15 into the receiving port 12 under the action of the blowing port 14, and the fertilizer is sucked into the waste box 26 under the action of the vacuum pump 25.

[0056] When the punch hole waste is cleaned, the hand wheel 3 is continuously rotated, and the two groups of movable pins 10 are gradually transferred from the ④ point to the ⑤ (①) point in the first groove and the second groove of the left cam 8 and the right cam 31, at this time, the positioning column 15 and the ejector pin 17 are gradually lifted into the die seat 13, and the ⑤ (①) effect is shown, at this time, the pressing ring 4 is opened, the punched cloth is taken out, and the next work is waited.

[0057] The application also provides a punching method, which comprises the following steps:

[0058] S1: when the hat is made, the cloth needs to be punched, the operator steps on the foot pedal 23, the vertical rod drives the swing seat 24 to move, so as to drive the U-shaped frame 7 to rise, at this time, the rotating shaft 20 is driven to rise, the left cam 8 and the right cam 21 are driven to rise, and then the positioning column 15 and the ejector pin 17 are driven to rise, at this time, the positioning column 15 is higher than the die seat 13 on the second support 2;

[0059] S2: at this time, the cloth to be punched is taken out, the punching position of the cloth is coincided with the positioning column 15, the cloth is compacted, the foot pedal 23 is loosened, at this time, the U-shaped frame 7 is lowered, so as to drive the positioning column 15 to descend, at this time, the two movable pins 10 are respectively located at the twelve o'clock direction position in the first groove and the second groove;

[0060] S3: at this time, the rotating shaft 20 is rotated, so that the left cam 8 and the right cam 21 are rotated, the movable pin 10 matched with the left cam 8 moves along the first groove, so as to move from the twelve o'clock position to the nine o'clock direction position in the first groove, at this time, the positioning column 15 moves downward, the movable pin 10 matched with the right cam 21 moves along the second groove, so as to move from the twelve o'clock position to the nine o'clock direction position in the second groove, at this time, the ejector pin 17 moves downward;

[0061] S4: the rotating shaft 20 is continuously rotated, one of the movable pins 10 moves along the first groove, so as to move from the nine o'clock direction position to the six o'clock direction position, at this time, the positioning column 15 is stationary, the other movable pin 10 moves along the second groove, so as to move from the nine o'clock direction position to the six o'clock direction position, at this time, the ejector pin 17 stretches upward to pierce the cloth and fix the cloth;

[0062] S5: At this time, the right cam 21 touches the micro switch 18, and the micro switch 18 controls the cylinder 6 to work, so that the punch 5 cooperates with the die base 13 to punch a round hole in the fabric, thereby completing the punching of the hat.

[0063] From the above, it can be seen that the present invention is reasonably designed and can complete the positioning of the punching position of the cloth with simple operation.
