Referring to fig. 2, a schematic flow chart of a method for preventing a roller at a tail of a belt from being stuck by a sticky material according to an embodiment of the present invention is provided, where the method includes:
s101: measuring the distance between the travel switch and a belt at the tail part of the belt conveyor in real time;
the distance meter constantly measures the distance from the travel switch to the belt at the tail of the belt conveyor, records the constantly acquired distance data and transmits the constantly acquired distance data to the travel switch.
S102: according to the distance between the belt at the tail of the belt conveyor and the travel switch, different processing signals are generated and sent, and the method specifically comprises the following steps:
determining an initial distance between the belt conveyor tail belt and the travel switch, and then determining at least 4 intervals between the belt conveyor tail belt and the travel switch: the travel switch comprises a first interval, a second interval, a third interval and a fourth interval, wherein each interval from the first interval to the fourth interval is closer to the travel switch;
and setting the first interval as an early warning interval, the second interval as an alarm interval, the third interval as a deceleration interval and the fourth interval as a shutdown interval.
For example: the distance between the starting travel switch and the belt at the tail of the belt conveyor is 50 mm, the distance between the travel switch and the belt at the tail of the belt conveyor is divided into 4 sections, wherein the distance between the end point of the first section close to the travel switch and the travel switch is 40 mm, the distance between the end point of the second section close to the travel switch and the travel switch is 30 mm, the distance between the end point of the third section close to the travel switch and the travel switch is 20 mm, the distance between the end point of the fourth section close to the travel switch and the travel switch is 10 mm, the end point of the first section close to the travel switch is the end point of the second section farthest from the travel switch, the end point of the second section close to the travel switch is the end point of the third section farthest from the travel switch, and the end point of the third section close to the travel switch is.
Therefore, by taking the travel switch as an origin, the first interval is 30-40 mm, the second interval is 20-30 mm, the third interval is 10-20 mm, and the fourth interval is 0-10 mm; setting the first interval as an early warning interval, the second interval as an alarm interval, the third interval as a deceleration interval and the fourth interval as a shutdown interval.

When the belt at the tail part of the belt conveyor is closer to the travel switch and is within the alarm interval, the alarm bell is larger and larger.
If the received processing signal is a belt conveyor deceleration signal, controlling the belt conveyor to operate in a deceleration mode;
if the received signal is a belt conveyor deceleration signal, the material stuck on the rollers at the tail of the belt conveyor is relatively more, a certain influence is already exerted on the operation of the belt conveyor, and in order not to influence the normal operation, the motor of the belt conveyor is controlled to slow down the operation speed of the belt conveyor according to the belt conveyor deceleration signal; and when the belt at the tail part of the belt conveyor is closer to the travel switch and is positioned in the deceleration interval, the running speed of the belt conveyor is slower and slower, and the deceleration prompting ring of the belt conveyor is sent out all the time when the belt conveyor decelerates until the worker processes the deceleration prompting ring.
And if the received processing signal is a belt conveyor stopping signal, controlling the belt conveyor to stop.
Receiving belt feeder shut down signal, gluing the material on belt feeder afterbody cylinder this moment and probably leading to the belt fracture or leading to the dead possibility of belt feeder card, in order not to influence the progress of operation, control belt feeder is shut down.
The belt machine is controlled to stop under the special condition that when the belt breaks, a large amount of materials are stuck to the tail roller in a large amount of short time, so that the belt directly touches the travel switch, and the belt machine can be directly stopped at the moment.
The intervals in the above embodiments may be multiple, or other processing measures other than the pre-warning, the alarm, the deceleration and the shutdown may be performed in different intervals according to actual conditions, and details are not described here.
