Problems solved by technology

[0002] The current full-open hydraulic paper cutter anti-cutting safety device uses multiple diodes to transmit signals to correspond to the received signals. When in use, the diodes’ transmission and reception need to correspond one-to-one, because the apertures of transmission and reception are very small and the signals are too weak. , the indicator light is not on, the error is large, the signal cannot be transmitted if there is a slight deviation or the signal deviates from the diode, false alarms occur, the failure rate is high, and it is often shut down to be repaired, which greatly affects the utilization of the equipment, and its diode and The circuit board is easily burned out and has a high failure rate, let alone functioning

Embodiment Construction

[0010] The present invention as figure 1 shown.

[0011] The full-open hydraulic paper cutter anti-hand safety device includes a full-open hydraulic paper cutter 1 and a working platform 2, and a grating signal transmission device 3 is installed on both sides of the full-open hydraulic paper cutter 1 above the working platform 2.

[0012] The grating signal transmission device 3 is an LDKS-Ⅲ photoelectric protector.

[0013] The working principle of LDKS-Ⅲ type photoelectric protector is that the emitter on the left side of the machine emits 4 beams of infrared beams with a thicker diameter, which are reflected to the left by the reflector on the right, and then the emitter on the left receives each beam of infrared beams by itself. Form a row of 8-beam infrared light curtains, and the arm can block one of the beams at will, which can disconnect the signal for protection. The advantages of this system compared with the original device are: the diameter of each beam of indepe...

Abstract

The invention provides a hand cutting prevention security device of a full-open hydraulic paper cutter. The device comprises the full-open hydraulic paper cutter and a working platform, and is characterized in that grating signal transmission devices of LDKS-II type photoelectric protectors are correspondingly arranged at the two sides of the full-open hydraulic paper cutter above the working platform. As the emitting distances of the grating signal transmission devices are far (reaching decade meters) and the reflecting areas thereof are large, the device adopts the grating signal transmission devices to wholly form an infrared light curtain wall, the existence of shielding objects can be accurately judged, the fault phenomenon of wrong actions or no operation caused by weak signals is radically not generated, the stop time is shortened, the machine working efficiency is improved, the most important is that the safety protection coefficient is greatly improved, the application time is long, no fault exists, the cost is lower, and the device is suitable for the security requirements.

Description

technical field [0001] The invention relates to the printing machinery industry, in particular to a full-open hydraulic paper cutter anti-cutting hand safety device. Background technique [0002] The current full-open hydraulic paper cutter anti-cutting safety device uses multiple diodes to transmit signals to correspond to the received signals. When in use, the diodes’ transmission and reception need to correspond one-to-one, because the apertures of transmission and reception are very small and the signals are too weak. , the indicator light is not on, the error is large, the signal cannot be transmitted if there is a slight deviation or the signal deviates from the diode, false alarms occur, the failure rate is high, and it is often shut down to be repaired, which greatly affects the utilization of the equipment, and its diode and The circuit board is easily burned out and has a high failure rate, let alone functioning. Contents of the invention [0003] In order to so...
