Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to the figure 1, the invention provides a filament cutter running sheet imaging detection alarm device which comprises a filament cutter, an imaging detection mechanism, a turnover mechanism, an alarm mechanism and a PLC (programmable logic controller).

The imaging detection mechanism is arranged at the outlet vibration groove of the tobacco cutter, the material condition behind the tobacco cutter is detected through photographing and forming, and the purpose of detecting whether tobacco shreds contain tobacco flakes or not is achieved through comparing the photographed pictures with the stored pictures.

The turnover mechanism is arranged in the tobacco shred outlet vibration groove and can turn over the tobacco shreds at the outlet vibration groove of the tobacco cutter.

The alarm mechanism is used for sending out an alarm prompt when the imaging detection mechanism detects that the tobacco shreds contain tobacco flakes;

the PLC controller is used for receiving the contrast signal of the imaging detection mechanism and transmitting the contrast signal to the alarm mechanism.

The alarm mechanism, the imaging detection mechanism and the turnover mechanism are electrically connected with the PLC; the signal output end of the imaging detection mechanism is connected with the signal input end of the PLC controller, and the signal output end of the PLC controller is connected with the signal input end of the alarm mechanism.

The filament cutter sliding imaging detection alarm device disclosed by the invention can effectively detect tobacco flakes in tobacco shreds and remind an operator to maintain the filament cutter as soon as possible. Overturn the pipe tobacco through tilting mechanism, two formation of image detection mechanism are located tilting mechanism's front and back both sides to in effectively detecting the upper surface that the pipe tobacco did not overturn and the lower surface after the upset, avoid the smoked sheet to mix in the pipe tobacco bottom and the condition that can't detect out produces, alarm mechanism can judge the severity of things according to two formation of image detection mechanism's contrast signal simultaneously, so that operating personnel makes as early as possible and handle effectively.

Furthermore, a button is arranged on the alarm mechanism and used for cutting off a contrast signal transmitted to the alarm mechanism by the PLC. When the operator receives the alarm sound sent by the alarm mechanism, the signal sent to the alarm mechanism by the PLC can be cut off through the button, so that light pollution and noise pollution are avoided.

Furthermore, the number of the imaging detection mechanisms is two, the two imaging detection devices are respectively arranged on the front side and the rear side of the turnover device, when the imaging detection mechanisms are implemented, the pictures shot by the imaging detection mechanisms on the front side are images displayed on the surface of the tobacco shreds when the tobacco shreds are not turned over, and the pictures shot by the imaging detection mechanisms on the rear side are images displayed on the bottom of the tobacco shreds when the tobacco shreds are turned over to the surface, so that the omnibearing detection on the tobacco shreds is ensured, and the incomplete detection caused by a single imaging detection mechanism is avoided.

Furthermore, the alarm mechanism has two working states, when one imaging detection mechanism observes a signal of the existence of the tobacco flakes, the first-stage alarm state of the alarm mechanism is triggered to indicate that the tobacco flakes exist on the surface or the bottom of the tobacco shreds, and the fault of the tobacco cutter at the moment belongs to a lighter state; when the two imaging detection mechanisms observe the tobacco flakes, a secondary alarm state of the alarm mechanism is triggered, the surfaces of the surface tobacco flakes and the bottoms of the tobacco flakes contain the tobacco flakes, the shredder has serious faults and needs to be shut down and maintained urgently, and the severity of the secondary alarm state is higher than that of the alarm state.

Still further, the alarm mechanism comprises an LED display lamp, and when the alarm mechanism is in a primary alarm state, the LED display lamp is yellow; when the alarm mechanism is in a secondary alarm state, the LED display lamp is red. The severity of the primary alarm state and the secondary alarm state may be differentiated based on the LED display lights.

And furthermore, when the LED display lamp is red, the LED display lamp is in a red flashing state, and the warning effect is further achieved through the red flashing LED display lamp.

Furthermore, the alarm mechanism also comprises a buzzer, and when the alarm mechanism is in a primary alarm state, the buzzer sends out short buzzing sound; when the alarm mechanism is in the secondary alarm state, the buzzer sounds rapidly. The display lamp mainly achieves the warning effect through the visual effect, but the visual field of people is limited, the possibility that the LED display lamp is located in the visual field blind area can occur, and the buzzer can achieve the further warning effect on the operating personnel through the auditory effect. More specifically, the buzzer may distinguish the severity of the failure by the difference in sound.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
