It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A method for forcibly starting a protection device of a drying machine is characterized in that a control module presets equipment starting conditions including a protection device unlocking signal, a protection device locking confirmation signal and an equipment starting signal, and equipment can be started only by receiving the four signals in sequence.
In a preferred embodiment, before starting the equipment, only the unlocking signal of the protection device is kept in the open state, and the locking signal of the rest protection devices, the locking confirmation signal of the protection device and the starting signal of the equipment are all required to be in the closed state.
In a preferred embodiment, the control module further includes a reset signal, regardless of the sequence of the signals received by the control module, only the protection device unlock signal is kept in the on state, the rest of the protection device lock signal, the protection device lock confirmation signal and the device start signal are all required to be in the off state, and at this time, the starting reset signal clears the signals received by the preamble.
A protection device capable of being forcibly started comprises a protection rod 1, a connecting rod 2, a guide rail 3, a slide block 4, a locking mechanism 5, a first sensor 6, a second sensor 7, a third sensor 8 and a starting switch 9, wherein the protection rod 1 is in a half-bag type structure, two ends of the protection rod are rotatably connected with a frame through a rotating shaft, the guide rail 3 is arranged on the frame, the slide block 4 is arranged on the guide rail 3 in a sliding manner, two ends of the connecting rod 2 are respectively hinged with the slide block 4 and the protection rod 1, the locking mechanism 5 is arranged on the protection rod 1, the protection rod 1 is in a locking state (the protection rod 1 is in a horizontal state) by using the locking mechanism 5, the first sensor 6 and the second sensor 7 are arranged at two ends of the guide rail 3, the third sensor 8 is arranged on the frame at one side of the protection rod 1 in the locking state, the starting switch 9 is arranged near the third sensor 8, so that the starting signal of the working personnel can be started conveniently. When locked, a protection area is formed by the protection bar 1 and the link 2 to protect workers from being hit by the drying cylinder.
In one embodiment, as shown in fig. 1-4, a chute 10 is horizontally disposed on the frame, and the third sensor 8 is slidably disposed on the chute 10. In a specific embodiment, the third sensor 8 slides below the protection bar 1 when the protection bar 1 is locked. Preferably, the third sensor 8 is slidably connected with the chute 10 through a support block for protecting the third sensor 8 and temporarily supporting the protection rod 1.
In one embodiment, as shown in fig. 1 to 4, the locking mechanism 5 includes a locking assembly and a transmission rod 51, the locking assembly is disposed on two sides of the protection rod 1, the locking assembly includes a locking housing 52, a locking pin 53, a spring 54, a pull wire 55 and a guide wheel 56, the locking housing 52 is disposed on the protection rod 1, the locking pin 53 and the spring 54 are disposed in the locking housing 52, and the spring 54 pushes the locking pin 53 to make one end of the locking pin protrude from the locking housing 52 and then clamp the protection rod to the rack, so that the protection rod 1 is fixed to the rack.

Then, the starting switch is pressed down, a starting signal is sent, and the equipment is started smoothly.
The second situation, if the staff is lazy, all set up the response piece on first sensor 6, second sensor 7 and third sensor 8 for each signal is received all the time to the controller, and presses starting switch, and is invalid this moment.
And in the third case, when the starting switch is pressed to start the equipment, the locking mechanism 5 is opened to enable the protection rod 1 to be in an open state, the reset switch is pressed to clear the received signal of the controller, and the equipment can be started by repeating the steps in the first case.
The above are merely preferred embodiments of the present invention, and are not intended to limit the scope of the invention; it is intended that the following claims be interpreted as including all such alterations, modifications, and equivalents as fall within the true spirit and scope of the invention.
