Description

Electric Silicone Gun

The invention relates to an electric silicone glue gun, which is mainly used for filling silicone glue to combine two objects.

The known silicone guns are mainly divided into two types: manual silicone guns and electric silicone guns. The manual silicone gun uses a round rod with a groove, and a front push piece. The front push piece has a round hole, which is used to clamp The round rod is used to drive the round rod to push forward to drive the silicone rubber tube to perform the silicone rubber filling operation. Although the price and cost are low, the speed is slow, and repeated force is required to cause fatigue. Since the round rod is blocked by the round hole, There are only 2 points where it is stuck, and it cannot withstand multiple operations, that is, wear and tear, so it needs to be purchased and updated from time to time.

It is known that the electric silicone guns currently on the market are used by major manufacturers in Europe, America and Japan. The motor drives the planetary gear set and the spur gear reduction is combined with the rack drive, and the amount of glue output is different due to different usage occasions. Therefore, the gear The driving speed of the bar must be adjustable, and when the silicone rubber is used up, the rack must be quickly reset to replace the new silicon rubber tube. If the motor is driven by the reverse direction, the rapid reset of the rack cannot be achieved, so the speed of the rack can be adjusted. And the rapid reset requirement of the rack must use electronic speed regulation of the motor, and 2 sets of planetary gear sets A and B drive, the A planetary gear set is combined with the motor, the B planetary gear set is combined with the rack, and the A and B Each of the B planetary gear sets has a spur gear, which is used to connect the A and B planetary gear sets, and the B planetary gear set has a mechanism connected with a switch, so that the rack can be quickly reset, and because the electric silicone gun has a high speed and pressure Therefore, the aluminum tube turning tooth is used as the sleeve, so the structure is complex, the volume is large, the cost is high and the energy consumption is high.

In view of this, it is indeed necessary to improve the above deficiencies. The present invention has simple structure, small volume, easy processing and manufacturing, low cost and energy saving.
