The vertical glue outlet pipe 17 can also be clamped on the pressing parts 7 of the two pump heads 8 by using the connecting line of the pump heads 8 in the two glue containers 10 as the central axis, and the rotating shaft of the stirring motor is arranged on the connected structure of the shoulders of the two containers on the central axis of the pressing head and is positioned in the middle of the two pump heads 8, so that glue can smoothly enter the mixing container when the two glue outlets 6 discharge glue. The two glue containers 10 of the invention can also be designed into a C-shaped conjoined structure, the outside of which is provided with a container with the same shape or similar volume and larger volume, heat transfer media such as water, heat conduction oil and the like are arranged in the container, an electric heater is arranged, the outside of the C-shaped conjoined structure is provided with a heat insulation layer, of course, the heat transfer media and the electric heater can also be directly served by an electric heating film, an electric heating sheet or an electric heating wire, and the electric heating plug can be used as a power supply by.

The play of pump head 8 upper end is glued the riser and is higher than the bottom of going out gluey chamber 5, goes out gluey chamber 5 bottom and is the slope form, and it is minimum to go out to glue to chew, goes out to glue the riser upper end of 5 bottoms in gluey chamber and has to go out to glue the bevel connection that the direction slope was chewed, and the bevel connection is lower than the bottom of going out gluey chamber 5. The upper part of the glue outlet vertical pipe can also be arranged into a parabolic shape which is deviated to the glue outlet nozzle, and the lower edge of the opening of the glue outlet vertical pipe is higher than the bottom of the glue outlet cavity 5. In order to facilitate cleaning, the end of the cleaning pipe of the cleaner is provided with a nozzle cap 6b which can be hermetically sleeved with the rubber nozzle 6. The cleaner can also be arranged at the top of the box body, so that the nozzle cover 6a at the tail end of the cleaning pipe is sleeved on the glue outlet nozzle 6 and then the cleaner is extruded to realize cleaning, and the cleaning glue liquid can flow back into the cleaner with the height lower than the glue outlet nozzle.
