Description

An automatic stop and alarm device used when the hopper of the waste conveying line is full

technical field

The utility model relates to the technical field of waste material treatment, in particular to an automatic stop and alarm device used when the hopper of the waste material conveying line is full.

Background technique

According to preliminary statistics, when the waste conveying line is running, there are 7-8 times a year on average that the hopper is full due to various reasons, and the waste material slips into the conveying chain and the shutdown is caused. All maintenance personnel will be employed each time, 3- It takes about 120 minutes for 4 production line personnel to troubleshoot each time, and the average shutdown is about 60 minutes each time. It takes a lot of manpower and material resources to clean up waste and repair each time. Chinese Patent Publication No. CN201449651U, published on May 5, 2010, a utility model patent named "Mold Blocking Alarm Device" discloses a mold blocking alarm device, including a base, an induction sheet and a proximity switch. Proximity switch, the middle part of the induction sheet is hinged with the base, one end of the induction sheet acts on the proximity switch, the other end acts on the material extruded from the mold, and the proximity switch is connected to the alarm light. The utility model is applicable to all extruded plastic production lines. During the extrusion production of plastic-steel profiles, when mold blocking occurs, it will alarm in time, deal with it in time, produce less waste, and avoid waste and equipment accidents caused by long-term mold blocking. The disadvantage is that the sensitivity of the proximity switch is still insufficient, and sometimes the phenomenon of false alarms occurs, and the alarm efficiency is low.

Utility model content

The purpose of this utility model is to overcome the defect that the device will stop when the hopper of the waste conveying line is full in the prior art, and to provide an automatic shutdown and alarm device used when the hopper of the waste conveying line is full, through which relevant personnel can Keep abreast of the fullness of the hopper, and at the same time, it will automatically stop to facilitate relevant personnel to take corresponding measures in time.

The purpose of this utility model is to be realized through the following technical solutions:

An automatic shutdown and alarm device used when the hopper of the waste conveying line is full, including a controller, the controller is connected with a photoelectric sensor, the controller is also connected with the sound and light alarm relay through the sound and light alarm relay, and the controller is also operated by a motor The relay is connected to the motor. The photoelectric sensor detects the waste in the hopper. Once the waste is found to be full, the photoelectric sensor sends a signal to the controller, and the controller controls the sound and light alarm relay to make the sound and light alarm relay alarm; shutdown. This device effectively prevents the waste material from slipping back into the conveying chain and blocking the waste line when the waste material is full.

As a preferred solution, the acousto-optic alarm is arranged on the column of the production line. The sound and light alarm is installed on the column of the production line, which is beneficial for relevant personnel to find out in time and take corresponding measures.

As a preferred solution, the number of photoelectric sensors is two, and the photoelectric sensors are respectively arranged on both sides of the hopper. The advantage of installing photoelectric sensors on both sides of the hopper is that it can detect the fullness of the hopper more accurately and prevent false alarms.

As a preferred solution, the controller is a PLC controller.

The beneficial effect of the utility model is that the automatic shutdown and alarm device can automatically detect whether the hopper of the waste conveying line is full, and once the hopper is full, it can send an alarm and stop the motor. The utility model has the advantages of simple structure, low price and easy realization.

Description of drawings

Fig. 1 is a kind of circuit principle connection diagram of the utility model.

Among them: 1. Controller, 2. Photoelectric sensor, 3. Sound and light alarm relay, 4. Sound and light alarm, 5. Motor running relay, 6. Motor.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment: An automatic shutdown and alarm device used when the hopper of the waste conveying line is full, its circuit principle connection diagram is shown in Figure 1, including a controller 1, which is a PLC controller. The controller is connected with the photoelectric sensor 2 , the controller is also connected with the sound and light alarm 4 through the sound and light alarm relay 3 , and the controller is also connected with the motor 6 through the motor running relay 5 . The sound and light alarm is set on the column of the production line. The number of photoelectric sensors is two, and the photoelectric sensors are respectively arranged on both sides of the hopper.

The photoelectric sensor detects the waste in the hopper. Once the waste is found to be full, the photoelectric sensor sends a signal to the controller, and the controller controls the sound and light alarm relay to make the sound and light alarm relay alarm; shutdown.
