[0034] a base 100;

[0035] a stamping machine 200, comprising a driving part 210, a clutch part 220 and a stamping part 230, the stamping part 230 is installed on the base 100 and the lower part is an output end, the power of the driving part 210 is transmitted to the stamping part 230 through the clutch part 220;

[0036] a pedal part 300, provided with a first switch responding to the stepping action and provided with an upward output connector 310;

[0037] a control assembly, comprising a rod seat 410 and a swing rod 420 rotatably arranged on the rod seat 410, one end of the swing rod 420 is matched with the clutch part 220 and connected to the stamping part 230 through an elastic member, the other end of the swing rod 420 is connected to the connector 310, wherein the rotation of the swing rod 420 controls the operation of the clutch part 220;

[0038] an electromagnetic switch 500, provided with a telescopic lock shaft corresponding to the swing rod 420, wherein the lock shaft is matched with the swing rod 420 to lock the swing rod 420 after being extended;

[0039] a horizontal photoelectric switch 600, arranged at the front of the output end of the stamping part 230 and comprising two side photoelectric functional heads 610 arranged in pairs, the two side photoelectric functional heads 610 are oppositely arranged at both ends of the base 100 in the width direction;

[0040] wherein, when the first switch and the horizontal photoelectric switch 600 are both positively triggered, the electromagnetic switch 500 drives the lock shaft to retract; when the first switch or the horizontal photoelectric switch 600 is negatively triggered, the electromagnetic switch 500 drives the lock shaft to extend.

[0041] In the prior art, the stamping machine controlled by the foot pedal generally does not set a sensing safety structure; in the process of use, the user continuously punches in the process, and the urgent demand for the improvement of the use speed causes safety hazards.

[0042] The stamping machine anti-hitting structure provided by the utility model provides the base 100 as the structural basis, and provides the installation basis for the subsequent components.

[0043] The stamping machine 200 comprises a driving part 210, a clutch part 220 and a stamping part 230. The stamping part 230 is installed on the base 100 and has an output end at the lower part. The power of the driving part 210 is transmitted to the stamping part 230 through the clutch part 220.

The structure of the clutch part 220 can be a pin type, and the specific type is not limited.

[0044] The pedal member 300 is provided with a first switch responding to the treading action and an upward output connecting piece 310. The treading action of the pedal member 300 can also control the downward pulling of the connecting piece 310.

[0045] The control assembly comprises a rod base 410 and a swing rod 420 rotatably arranged on the rod base 410. One end of the swing rod 420 is matched with the clutch part 220 and is connected to the stamping part 230 through an elastic piece. The elastic piece is in a stretching state and is used for resetting the swing rod 420. The other end of the swing rod 420 is connected to the connecting piece 310. When the pedal member 300 is treading, the swing rod 420 is rotated downward and pulled, the restriction of the swing rod 420 to the clutch part 220 disappears, and the stamping part 230 works. When the pedal member 300 is not treading, the swing rod 420 is rotated upward and pulled by the elastic piece, the restriction of the swing rod 420 to the clutch part 220 is formed, and the working of the stamping part 230 is stopped.

[0046] The electromagnetic switch 500 outputs a lock shaft which is retractable and corresponds to the swing rod 420. When the lock shaft is extended, it cooperates with the swing rod 420 to lock the swing rod 420.

[0047] The horizontal photoelectric switch 600 is arranged at the front of the output end of the stamping part 230 and comprises two side photoelectric functional heads 610 arranged in pairs. The two side photoelectric functional heads 610 are oppositely arranged at the two ends of the base 100 in the width direction. It is not limited which of the two side photoelectric functional heads 610 performs the emission process and which performs the receiving process. When the light path is normal, it is determined that there is no abnormal intrusion, otherwise it is determined that there is abnormal intrusion. When the first switch and the horizontal photoelectric switch 600 are both positively triggered, the electromagnetic switch 500 drives the lock shaft to retract, at this time the stamping part 230 can work. When the first switch or the horizontal photoelectric switch 600 is negatively triggered, the electromagnetic switch 500 drives the lock shaft to extend, at this time the working of the stamping part 230 is stopped. The negative triggering of the first switch indicates that the pedal member 300 is not treading, and the negative triggering of the horizontal photoelectric switch 600 indicates that the light path between the two side photoelectric functional heads 610 is blocked, indicating that there is abnormal intrusion.

[0048] In summary, the working of the clutch part 220 can form and break the linkage between the driving part 210 and the stamping part 230, the pedal part 300 is provided with a first switch responding to the stepping action, the rotation of the swing lever 420 controls the working of the clutch part 220; when the first switch and the horizontal photoelectric switch 600 are both positively triggered, the electromagnetic switch 500 drives the lock shaft to retract, at this time the stamping part 230 can work; when the first switch or the horizontal photoelectric switch 600 is negatively triggered, the electromagnetic switch 500 drives the lock shaft to extend, at this time the working of the stamping part 230 stops, thereby ensuring the safety during use.
