If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the invention, unless otherwise explicitly defined, terms such as set, mounted, connected and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the terms in the invention in combination with the specific contents of the technical solutions.

Referring to fig. 1 to 3, the utility model relates to a glue pump early warning device, including support 10, propeller 20, container 30 and monitoring module 40. Referring specifically to fig. 1, the support 10 and the container 30 are both fixed to the ground 50, the support 10 being a vertical bar or panel, the pusher 20 then being fixed to the support 10, the container 30 being located below the pusher 20. The output end of the pusher 20 is provided with a pressing rod 21 and a pressing plate 22, the area of the pressing plate 22 is large, the moving path of the pressing plate 22 is in the container 30, and the pressing rod 21 pushes the pressing plate 22 to move downwards so as to extrude the glue. In this embodiment, the propeller 20 adopts a motor screw propulsion mode, and the motor drives the screw rod to rotate and then the nut stretches, so as to drive the pressing rod 21.

The monitoring module 40 is fixed on the bracket 10 and comprises a control panel, a button 41, a distance sensor 42 and a counting sensor, wherein the control panel is connected with the propeller 20, the button 41, the distance sensor 42 and the counting sensor, and a contact of the distance sensor 42 is positioned on a moving path when the pressure lever 21 descends to a limit position. In fig. 1, it can be seen that the side of the push rod close to the platen 22 is cylindrical, and the side of the push plate away from the platen 22 is provided with a plurality of posts for uniformly receiving the pushing force of the pusher 20. When the device is used, the control board resets the propeller 20 after acquiring the pulse of the distance sensor 42, resets the propeller 20 after acquiring the pulse of the button 41, acquires the pulse frequency of the distance sensor 42 by the counting sensor within a set time and feeds back the pulse frequency to the control board, and when the pulse frequency within unit time exceeds a threshold value, the control board stops the propeller 20. For example, the pressing rod 21 needs to be lifted and lowered three times within one hour, the pulse interval received by the control board each time is about 20min, if the pressing rod 21 is lifted and lowered too frequently or slowly, the pulse interval can be changed, and if the change exceeds a threshold value, the whole glue pump system is completely stopped.

Preferably, the monitoring module 40 further comprises an alarm, and the control board starts the alarm after acquiring the pulse of the distance sensor 42. The glue pump early warning device is used for automatically judging whether the glue pump is empty to pump and frequently acts so as to eliminate the hidden trouble of the glue pump and ensure the normal operation of equipment and a production line.

Referring specifically to fig. 2, the monitoring module 40 is a box as a whole, the button 41 is disposed outside, the distance sensor 42 is disposed outside the box, and the distance sensor 42 is connected to the inside of the box through a wire. The cartridge may be mounted to the support 10 during assembly, with the contacts of the sensor 42 projecting appropriately.

Preferably, the alarm is a buzzer, a flashlight or a combination thereof. If a buzzer is adopted, the buzzer can be directly arranged on the control panel, and the groove is formed in the box body, so that sound waves can be transmitted conveniently. If a flashlight is used, the flashlight may be mounted on the stand 10 in a more prominent position and then connected to the interior of the case by a wire.

In other embodiments, the distance sensor 42 is an infrared sensor or a laser sensor, which uses the principle that light is blocked or reflected to accurately reflect the position of the pressing rod 21. In order to save cost, the distance sensor 42 is preferably a travel switch, and it is only necessary to determine that the pressing rod 21 passes a certain position.

referring to fig. 3 in particular, preferably, the control panel adopts a plc programmable control system, the debugging is simple, the operation is stable, a counting sensor is integrated in the plc programmable control system, I8.4 is a counting and timing sensor signal, I8.5 is a reset button, I8.6 is a positioning sensing signal, O19 is an alarm and air source cut-off output signal, T160 is a counter, C100 is a timer, the operation process includes that when the glue pump starts, I8.4 is operated, T160 starts timing, and at the same time, C100 counts for less than 3 times within the time set by T160 (60S) to indicate that the operation frequency of the glue pump is normal, T160 automatically resets after timing 60S is ended, and enters the next cycle, when the C100 counts is greater than or equal to 3 times, O19 outputs an alarm and cuts off the air source of the glue applicator, when the fault is cleared, I8.5 is reset, when the I8.6 sensor has an input signal to indicate that the glue pump is in an empty pumping state, and O19 outputs an alarm and cuts off to remind of glue change.

the glue pump early warning device is used for automatically judging whether a glue pump is empty to pump and frequently acts so as to eliminate the hidden trouble of the glue pump and ensure the normal operation of equipment and a production line.
