Therefore, it is necessary to provide a bidirectional belt anti-blocking early warning device to ensure the continuity and smoothness of production and feeding.
Disclosure of Invention
An object of the utility model is to provide a stifled early warning alarm device is prevented to two-way belt solves the two-way transportation process among the prior art, at blanking hood department putty easily, causes whole production line feed to interrupt, is difficult to the problem of discovery at the putty initial stage.
The two-way belt of a two-way belt anti-blocking early warning device both ends all be provided with hood 1: still include switch installing support 2, photoelectric detection switch 3, PLC control system 5, alarm device 6, be provided with transparent window 4 on the lateral wall of 1 one side of hood, switch installing support 2 installs in 1 one side of hood, and switch installing support 2 and transparent window 4 set up relatively, install photoelectric detection switch 3 on the switch installing support 2, and photoelectric detection switch 3 is just to transparent window 4, and photoelectric detection switch 3 and PLC control system 5's input are connected, and PLC control system 5's output and alarm device 6 are connected.
The further technical scheme is that the switch mounting bracket 2 is made of angle steel, and the angle steel is fixedly connected with the photoelectric detection switch 3 through a waist hole.
In a further technical scheme, the transparent window 4 is made of an organic glass plate 8, and the organic glass plate 8 is installed on the side wall of the hood 1 through bolts.
Compared with the prior art, the beneficial effects of the utility model are that: through the design that the transparent window is arranged on the side wall of one side of the hood, the photoelectric detection switch is opposite to the transparent window, so that the photoelectric detection switch is convenient to detect; the putty information is detected through the photoelectric detection switch, and with signal transmission to PLC control system, PLC control system gathers the positive and negative signal of changeing of motor, and carries out internal logic with the putty signal that photoelectric sensor detected and judges, detects the putty signal when the photoelectric detection switch, and corresponding positive and negative signal is gathered to PLC control system, and alarm device reports to the police, has effectively avoided the wrong report alert among the putty testing process. Thereby effectively solved two-way belt conveyor in-process, easily at blanking hood department putty, cause whole production line feed to break off, be difficult to the problem of discovery when the putty is first sent out. The design can realize timely discovery of material blockage and guarantee the continuity and the fluency of production and feeding.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1-5 show a bidirectional belt anti-blocking early warning device, the two ends of the bidirectional belt are provided with a head cover 1: still include switch installing support 2, photoelectric detection switch 3, PLC control system 5, alarm device 6, be provided with transparent window 4 on the lateral wall of 1 one side of hood, switch installing support 2 installs in 1 one side of hood, and switch installing support 2 and transparent window 4 set up relatively, install photoelectric detection switch 3 on the switch installing support 2, and photoelectric detection switch 3 is just to transparent window 4, and photoelectric detection switch 3 and PLC control system 5's input are connected, and PLC control system 5's output and alarm device 6 are connected.
In the use process of the bidirectional belt, the blockage usually starts from the position of the hood 1 at one of two ends of the belt, the material during the blockage is in a relatively static state, in the normal production process, the material is in a flowing state, a transparent window is arranged on the side wall of one side of the hood, and the photoelectric detection switch is designed just to the transparent window, so that when the blockage is arranged at the position of the hood 1, the photoelectric detection switch can detect the blockage information through the transparent window. The photoelectric detection switch 3 has stronger stability, the detection distance is between 50 mm and 2000 mm, and the detection requirement on the materials can be met.
The PLC control system collects positive and negative rotation signals of the motor and carries out internal logic judgment with a material blocking signal detected by the photoelectric sensor. In a control program, an M110.7 point is used as a material blocking relay, after input signals of two detection switches are respectively connected with positive and reverse signals of a belt motor in series, the M110.7 is switched on by delaying for 3 seconds, a C25 counter is triggered by the rising edge of the M110.7 for counting, and a normally open contact of the M110.7 triggers a siren and a red alarm lamp respectively to complete audible and visual alarm.
Alarm device 6 includes upper winCC monitored control system and audible-visual alarm, audible-visual alarm device 6 is whistle and three-colour signal lamp, photoelectric detection switch 3 detects behind the putty signal, judge the processing through PLC control system 5 with the putty signal, and with putty information transfer to upper winCC monitored control system, utilize upper winCC monitored control system's alarming function, just can in time carry out alarm information on the upper level and pop out, and simultaneously, trigger whistle and three-colour signal lamp through electrical system and sound (bright) simultaneously, remind operating personnel in time to look over whether produce the putty in this position.
As shown in fig. 3, the switch mounting bracket 2 is made of angle steel, a waist hole is formed in the angle steel, and the angle steel is fixedly connected with the photoelectric detection switch 3 through the waist hole. Through the design of switch installing support 2, the installation of the photoelectric detection switch 3 of being convenient for is fixed, through the design in waist hole, is convenient for adjust photoelectric detection switch 3's mounted position.
As shown in fig. 1, 3 and 4, the transparent window 4 is made of a plexiglass plate 8, and the plexiglass plate 8 is mounted on the side wall of the head cap 1 by bolts. Through the design of organic glass for when hood 1 department putty, the photoelectric detection switch can see through organic glass board 8, and the detection switch of being convenient for detects the putty information in hood 1.
The working principle is as follows: when the material blocking device is used, the photoelectric detection switch 3 detects material information and transmits blocking information to the PLC control system 5, the PLC control system 5 collects forward and reverse rotation signals of the motor, and the forward and reverse rotation signals of the motor and the blocking signals detected by the photoelectric sensor perform internal logic judgment in the PLC control system; when the motor rotates forwards, the corresponding photoelectric detection switch 3 detects a material blocking signal, the PLC control system 5 collects the forward rotation signal of the motor, and the alarm device 6 gives an alarm; when the motor rotates reversely, the corresponding photoelectric detection switch 3 detects a material blocking signal, the PLC control system collects a reverse rotation signal, and the alarm device 6 gives an alarm.
