Description

An automatic alarm device for liquid level of can washing liquid

technical field

The utility model relates to the field of load monitoring, in particular to an automatic alarm device for liquid level of can washing liquid of pop-top cans.

Background technique

The aluminum material is stamped into an aluminum cup and then stretched to form an aluminum can. At this time, there will be lubricating oil in the aluminum can. Therefore, before the aluminum can enters the next process, it needs to be cleaned with a chemical cleaning agent by a can washer. The chemical cleaning agent used by the can washing machine to clean the aluminum cans is automatically pumped from the chemical cleaning agent container into the cleaning tank of the can washing machine through a metering pump. In order to ensure cleanness, it is necessary to ensure that there is enough chemical cleaning agent in the chemical cleaning agent container, so it is necessary to monitor the remaining amount of chemical agent in the chemical cleaning agent container. Such a monitoring method is to insert a stainless steel ruler with a scale into the container, and confirm the remaining amount of chemical cleaning agent in the container through the height soaked by the liquid medicine on the scale; It is necessary to observe the scale to know the remaining liquid. If the staff does not see the liquid remaining indicated by the scale in time, then they cannot know in time that the liquid remaining in the chemical cleaning agent container is insufficient. If the chemical cleaning agent is added to the chemical cleaning agent container, the chemical cleaning agent pumped by the metering pump may not be enough, which will affect the cleaning effect.

Detailed ways

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

As shown in Figures 1 to 3, an automatic alarm device for liquid level of cans for washing cans described in the present invention includes a rectangular bottom plate 1, a rectangular supporting plate 2 above the bottom plate 1, and a contact position sensor 21 , Alarm indicator light 4 and power supply. One side of the supporting plate 2 is hinged to one side of the bottom plate 1; four springs 11 vertically arranged on the bottom plate 1 are arranged between the supporting plate 2 and the bottom plate 1, and the four springs 11 are located at the bottom of the supporting plate 2. The opposite side of the hinged side; the contact position sensor 21 is arranged on the edge perpendicular to the hinged side of the support plate 2, and the contact of the contact position sensor 21 is located between the bottom plate 1 and the support plate 2; when the support plate 2 During the downward rotation, the contacts of the contact position sensor 21 will touch the base plate 1 and be pressed by the base plate 1. The warning indicator light 4 is electrically connected with the contact sensor 21; the contact position sensor 21 and the alarm are connected with the power supply. The warning indicator light 4 is arranged on the contact position sensor 21 .

The warning indicator light 4 is used as an alarm; the warning indicator light 4 is not necessarily arranged on the contact position sensor 21, but also can be arranged at other positions of the automatic alarm device for the washing liquid level of the pop can, or be arranged in other places where it is convenient for the staff to find s position. In order to make the alarm effect better, a buzzer can also be set as an alarm, and the buzzer is started by the contact position sensor 21 .

The quantity, specification and location of the springs 11 (located on the bottom plate 1) can be set according to the load capacity. The position where the contact type position sensor 21 is installed can be determined according to the load capacity.

Application of automatic alarm device for liquid level of can washing liquid:

Load is added on the support plate, the support plate 2 gradually presses the spring 11 , and finally the contact of the contact position sensor 21 is pressed by the base plate 1 . Gradually remove the load, the force of the support plate 2 pressing down on the spring 11 becomes smaller and smaller, and the spring 11 gradually resets; the spring 11 resets, that is, the support plate 2 can be lifted up, and the contact position sensor 21 moves upward with the support plate 2 When the load is less than the set weight, the contact of the contact position sensor 21 is no longer pressed by the base plate 1, and the contact position sensor 21 sends an electric signal to make the alarm indicator light 4 start the alarm function, that is, the alarm indicator light 4 flashes to the police If there is also a buzzer, the buzzer will start the alarm function and it will sound a buzzer. The alarm goes off.

The contact position sensor 21 can form an alarm circuit with the alarm indicator light 4 or/and the buzzer, and directly control the alarm indicator light 4 or/and the buzzer; it can also send a signal through the peripheral controller, the contact position sensor 21, After receiving the signal, the controller controls the alarm indicator light 4 or/and the buzzer to start the alarm function.

The effect of the spring 11 is to jack up the supporting plate 2, and when the load is less than the set weight, the contact of the contact position sensor 21 is no longer pressed by the base plate 1, and the alarm sends out an alarm.

The spring 11 is located on the opposite side of the hinged side of the support plate 2, so that the elastic force of the spring can reach a suitable utilization rate, the moving distance of the support plate can be made more obvious when the support plate rotates, and the structure of the whole device can be ensured when the support plate rotates. Stable, the load can be firmly placed on the upper side of the support plate.

Alarm indicator light and buzzer: Through visual and auditory alarm effects, it is easier to be found by people, ensuring the smooth operation of the entire device.

When the load alarm device is used to monitor the remaining amount of chemical cleaning agent solution, its application principle is as follows:

As shown in Figure 1 and Figure 2, the container 3 is placed on the supporting plate, and the chemical cleaning agent is filled into the container 3, the supporting plate 2 gradually compresses the spring 11, and finally the contact of the contact position sensor 21 is pressed by the bottom plate 1 . When the chemical cleaning agent is taken away, the remaining chemical cleaning agent is getting smaller and smaller, the force of the supporting plate 2 pressing down on the spring 11 is getting smaller and smaller, and the spring 11 gradually resets; the spring 11 resets, which can lift the supporting plate 2. The contact position sensor 21 moves upward with the support plate 2; when the amount of chemical cleaning agent is less than the alarm margin, the contact of the contact position sensor 21 is no longer pressed by the bottom plate 1, and the contact position sensor 21 sends out an electrical signal Make the alarm indicator light 4 start the alarm function, that is, the alarm indicator light 4 flashes the color of the alarm, if a buzzer is also provided, the buzzer starts the alarm function at this moment, and can buzz. The alarm goes off. The alarm margin is at least the remaining liquid capacity in the container 3 .

The utility model can monitor the load in real time, and when the load is less than the set weight, an alarm will be issued.

When the utility model is applied to monitor the remaining amount of chemical cleaning agent solution, when it monitors the amount of chemical cleaning agent in the container 3 in real time, when the liquid content in the container 3 is less than the alarming amount, an alarm can be issued. The staff can immediately know that the chemical cleaning agent is insufficient, and add the chemical cleaning agent to the container 3, so as to ensure that the chemical cleaning agent pumped by the metering pump is sufficient, and the aluminum can can have a good cleaning effect. The utility model is suitable for various situations where the liquid volume in the container needs to be monitored and an alarm is required when the liquid volume is less than a certain set value.

The utility model is not limited to the above-mentioned embodiment, if the various changes or modifications of the utility model do not depart from the spirit and scope of the utility model, if these changes and modifications belong to the claims of the utility model and within the equivalent technical scope, Then the utility model also intends to include these modifications and variations.
