It should be noted that the metering pump 310 may be a gear pump, or may be another type of pump, such as a plunger pump.

Referring to fig. 1 to 4, it is conceivable that, in some embodiments, a plurality of shut-off valves 800 are mounted on the integrated mounting member 100, the shut-off valves 800 being used to control opening and closing of the corresponding second flow passages 120, and the number of shut-off valves 800 is the same as the number of second flow passages 120. When the metering pump 310 is operated, the corresponding shut-off valve 800 opens the corresponding second flow passage 120. When the device stops working, the second flow passage 120 is closed by the stop valve 800, so that the liquid between the metering pump 310 and the stop valve 800 and between the metering pump 310 and the raw material container 200 can not contact with the external air, the liquid is prevented from deteriorating, and the device stops working for a long time and does not influence the next starting and use.

Specifically, the stop valve 800 may be configured as a push rod 721 valve, at this time, the stop valve 800 includes a valve rod and a driving device driving the valve rod to move, the valve rod is a working portion of the stop valve 800, the integrated mounting member 100 is provided with a third mounting hole communicated with the second flow channel 120, the driving device is mounted on the integrated module, the valve rod is connected to the driving device and slidably mounted on the third mounting hole, and one end of the valve rod corresponding to the second flow channel 120 can be accessed to control the on/off of the second flow channel 120. The stop valve 800 only needs to be installed in the third installation hole in a sealing mode through the valve rod, and the driving device only needs to be installed on the integrated installation part 100, so that the stop valve is simple and convenient to install.

It will be appreciated that the stop valve 800 may be arranged in other ways than the push rod 721 valve, for example, the stop valve 800 may be arranged as a ball valve, and may be mounted in a similar way as the push rod 721 valve, and the specific arrangement will not be described.

Referring to fig. 2-4, it is envisioned that in some embodiments, integrated mounting member 100 is fitted with a purge valve 900 for the entry of purging liquid, purge valve 900 being in communication with mixing tube 400. Specifically, the cleaning valve 900 is connected to the second flow channel 120 between the stop valve 800 and the mixing pipe 400, and after the glue dripping system completes its operation, a cleaning liquid can be introduced through the cleaning valve 900 manually or automatically to clean the liquid existing inside the mixing pipe 400.

Referring to fig. 1 to 4, it is conceivable that, in some embodiments, the present dispensing system further includes a dispensing control valve 700, the dispensing control valve 700 is disposed between the dispensing nozzle 500 and the mixing tube 400, and the dispensing control valve 700 is used for controlling the liquid to be extruded from the dispensing nozzle 500. Therefore, the stirring device is responsible for stirring and mixing of liquid, the glue dripping control valve 700 is responsible for glue dripping operation, the operation of the stirring device and the glue dripping control valve can be respectively carried out, and in the working process of the glue dripping control valve 700, the stirring assembly can always carry out stirring and mixing of the liquid, so that the liquid is fully mixed. Through the setting of the glue dripping control valve 700, the liquid extrusion amount can be accurately controlled according to the process requirements of products, and the production quality is improved.

Referring to fig. 5, in some embodiments, specifically, the glue dripping control valve 700 includes a valve body 710 and a control mechanism 720, the valve body 710 is installed at the lower end of the mixing tube 400, a third flow channel for liquid to flow in and out is provided in the valve body 710, the upper end of the third flow channel is communicated with the interior of the mixing tube 400, the glue outlet 500 is installed at the lower end of the third flow channel, the valve body 710 is provided with a first installation hole communicated with the third flow channel, the control mechanism 720 includes a push rod 721, the push rod 721 is movably installed in the first installation hole, and one end of the push rod 721 is movably installed in the third flow channel, so as to change the volume in the third flow channel. During glue dripping operation, one end of the push rod 721 moves towards the third flow channel, so that the volume in the third flow channel can be reduced, and high pressure is formed in the third flow channel, so that liquid can flow fast and is extruded from the glue outlet nozzle 500; then, one end of the push rod 721 moves towards the direction far away from the third flow channel, so that the volume in the third flow channel can be increased, negative pressure is formed in the third flow channel, the liquid at the glue outlet 500 is sucked back, meanwhile, the liquid in the mixing tube 400 can be sucked into the third flow channel, so that the third flow channel has enough liquid again, the next glue dripping operation can be continued, and the glue dripping speed is increased.

It can be understood that when the liquid at the glue outlet 500 is sucked back, the extruded liquid can be separated from the liquid in the glue outlet 500, so that the glue breaking and the wire drawing are realized, and the condition that the liquid drops on the product to influence the product quality can be avoided.

It can be understood that when the viscosity of the liquid is high or the dropping amount of the liquid is small, the flow rate of the liquid is low, and the dropping control valve 700 can accelerate the liquid in the mixing tube 400 to enter the third flow channel and extrude the liquid from the third flow channel more quickly, thereby increasing the dropping speed of the micro-amount of the liquid or the dropping speed of the high-viscosity liquid.

It can be understood that the push rod 721 moves along the direction away from the third flow channel, so that when negative pressure is formed in the third flow channel, the pressure of the liquid in the third flow channel can be released, the liquid does not have residual pressure, and the next liquid extrusion operation is not affected, so that the stability of each glue dripping operation can be improved.

Referring to fig. 5, in particular, the third flow channel includes a volume chamber 711, and a liquid inlet 712 and a liquid outlet 713 communicated with the volume chamber 711, the liquid inlet 712 and the liquid outlet 713 are respectively located at the upper side and the lower side of the volume chamber 711, the first mounting hole is communicated with the volume chamber 711, one end of the push rod 721 is movable in the volume chamber 711, and a gap large enough to allow liquid to flow through the gap is formed between the inner wall of the volume chamber 711 and the outer periphery of the push rod 721.

When the push rod 721 moves into the volume cavity 711, the effective volume in the volume cavity 711 is reduced to form high pressure, so that the liquid in the volume cavity 711 is extruded from the glue nozzle 500; when the push rod 721 moves in the direction away from the volume chamber 711, the effective volume in the volume chamber 711 increases to form a negative pressure, so that the liquid at the glue nozzle 500 is sucked back, and the liquid in the stirring assembly can be sucked into the volume chamber 711. The setting of the volume chamber 711 can increase the stroke range of the push rod 721, namely, the range of the volume change of the push rod 721, the maximum extrusion amount of the liquid is larger, and the working range of the glue dripping control valve 700 is larger.

It should be noted that, in addition to the arrangement described above, the glue-dropping control valve 700 may also be a plunger-type glue-dropping control valve 700 commonly used in the art.

It is conceivable that the extrusion amount of the liquid can be controlled by controlling the stroke of the push rod 721. Referring to fig. 5, in detail, the control mechanism 720 further includes a cylinder mounted on the valve body 710, the cylinder is in transmission connection with the push rod 721 to drive the push rod 721 to move, and the stroke of the cylinder is adjustable.

Through the arrangement, the stroke of the push rod 721 can be adjusted according to the extrusion amount of the liquid, and the requirement of each operation is ensured.
