Furthermore, one of the supporting plates is provided with a toggle counting switch which is electrically connected with the second conveyor belt.

Furthermore, a second baffle is clamped on two sides of the first conveyor belt, and corresponding openings are formed in the positions of the air exhaust pipe opening and the blanking slope of the second baffle.

The working principle is as follows: after the mask is manufactured, the mask is conveyed to the first conveying belt and moves forward along with the first conveying belt. When the gauze mask moves to the recognition mechanism below, recognition probe discerns the gauze mask on the first conveyer belt among the recognition mechanism, judge whether it is in horizontal placement state, if recognition probe judges that the gauze mask is not in horizontal placement state, then recognition probe sends the signal to the solenoid valve, the solenoid valve accepts the signal after the certain time delay and carries out fast opening/closing, when the solenoid valve is opened, the gauze mask that does not transversely place just in time passes through the mouth of pipe of airing exhaust, the compressed air that the mouth of pipe of airing exhaust blew off goes out the gauze mask on the conveyer belt and falls first conveyer belt to the unloading slope, slide into to collecting the frame along the unloading slope afterwards. And normal horizontal gauze mask then continues to move forward, jets into under inertial effect at last on first baffle, and because inertial effect, after the gauze mask contacted first baffle, its edge and the automatic parallel and level of laminating of first baffle, and then play and lead positive effect. The mask falls on the supporting plate after being guided, then the telescopic cylinder extends out of the telescopic cylinder, the lower pressing block is driven to push the mask out downwards, and the mask immediately falls on the second conveying belt below. After the telescopic cylinder is stretched and retracted for a predetermined number of times, the second conveyor belt is operated to convey the stacked mask forward to collect and stack the next stack of masks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the mask feeding device includes a first conveyor 10, and a recognition mechanism 20, a removing mechanism 30, a guiding and feeding mechanism 40, and a second conveyor 50, which are sequentially disposed along a forward direction of the mask on the first conveyor. Wherein, the identification mechanism comprises a frame 21 which is arranged above the first conveyor belt, and an identification probe 22 fixedly connected with the frame is arranged below the frame. This identification probe can discern the gauze mask on the first conveyer belt and judge whether it is transversely put. The removing mechanism comprises an exhaust pipe orifice 31 arranged on the side of the first conveyor belt, an electromagnetic valve 32 is arranged on the exhaust pipe orifice, and the electromagnetic valve is communicated with the compressed air through a pipeline. It should be noted that the electromagnetic valve and the identification probe are connected by an electrical signal. When the identification probe identifies the mask with the unsatisfactory placement state on the first conveyor belt, the identification probe sends a signal to the electromagnetic valve. The electromagnetic valve is delayed for a set time after receiving a signal and then is opened and closed quickly. The delay time is determined according to the conveying speed of the first conveyor belt. Namely, when the mask with the wrong state moves to the air exhaust pipe opening, the electromagnetic valve is opened and closed quickly, so that an air pulse is generated, and the mask with the incorrect placing state is blown away from the first conveyor belt by the air pulse. And the blown mask is collected for subsequent reuse. A blanking slope 33 opposite to the air exhaust pipe opening is arranged on the other side of the first conveyor belt. The mask falls on the blanking slope after being blown off the first conveyor belt. And then slid along the blanking ramp into a receiving frame 34 disposed below the blanking ramp. The guide blanking mechanism 40 includes a first baffle 41 facing the discharge side of the first conveyor belt, and support plates 42 are symmetrically disposed on both sides of the first baffle. The distance between the two supporting plates is less than the length of the mask. To ensure that the support plate cannot fall down due to the gravity of the support plate. Meanwhile, a telescopic cylinder 43 is also longitudinally arranged above the two supporting plates. The end of the telescopic rod of the telescopic cylinder is fixedly provided with a lower pressing block 44. The telescopic link is flexible to make the briquetting down exert a decurrent effort to the gauze mask in the backup pad, and this effort is fallen second conveyer belt 50 below lieing in the backup pad after leaving the backup pad with the gauze mask top. It should be noted that the telescopic cylinder is electrically connected with the second conveyor belt. After the telescopic cylinder stretches for a preset number of times, the second conveying belt steps forward by one station.

As a further improvement of the above embodiment, in order to accurately count each stack of masks on the second conveyor belt. One of the support plates is provided with a toggle counting switch 45. Specifically, the toggle counting switch is electrically connected with the second conveyor belt. This toggle count switch's theory of operation does, when having the gauze mask in the backup pad, when the gauze mask was pushed up from the backup pad, the gauze mask toggles toggle count switch, toggles technical switch and sends a signal to telescopic cylinder's counter, and telescopic cylinder's last counter (not shown in the figure) carries out quantity and adds up, if do not have the gauze mask in the backup pad, then telescopic cylinder does not receive the signal of toggling count switch, and quantity does not add up. Thereby ensuring the accuracy of the number of each pile of masks and saving the step of manually checking the number by workers.

As a further improvement of the above embodiment, in order to prevent the mask from falling off the first conveyor belt during the conveyance, second stoppers 60 are provided above the first conveyor belt and are sandwiched between the first conveyor belt and the second conveyor belt. Specifically, the second baffle is provided with openings 61 at the air exhaust pipe opening and the blanking slope.
