Description
Technical Field
The utility model relates to a hot melt adhesive rifle.
Background
Current hot melt adhesive gun passes through trigger and connecting rod and will glue excellent seat propelling movement forward to drive and glue the stick and walk forward, because the spring that sets up in the handle works under the higher environment of temperature for a long time, it is ageing easily, finally lead to processes such as the reseing of trigger and connecting rod to receive the influence, further lead to gluing the stick and go out the fluctuation range of gluey speed great.
Disclosure of Invention
The utility model aims to solve the above problem, provide a reliable hot melt adhesive rifle of ejection of compact, specifically realize by following technical scheme:
a hot melt adhesive gun comprises a gun body, a pressing rod, a driving wheel and a pinch roller, wherein the upper part of the gun body is provided with a glue stick inserting pipe, a heating pipe and a discharging nozzle which are sequentially communicated; the driving wheel is rotatably arranged in the middle of the gun body, and the upper edge of the driving wheel penetrates through the side wall of the rubber stick inserting pipe so as to be abutted against the rubber stick inserted in the rubber stick inserting pipe; the pressing wheel is rotatably arranged at the upper part of the gun body, and the lower side edge of the pressing wheel penetrates through the side wall of the rubber stick inserting pipe so as to be abutted against the rubber stick inserted in the rubber stick inserting pipe; one side of the driving wheel is coaxially connected with a gear which can rotate along with the driving wheel in the middle of the gun body; the lower part of the gun body is a handle part, the pressing rod is elastically inserted into the handle part, and the pressing rod extends out of the handle part outwards to form a pressing end outside the handle part; the part of the pressing rod, which is positioned in the handle part, is hinged with a driving gear, the driving gear is connected with the pressing rod through a torsional spring, a limiting block is arranged on the pressing rod, so that the driving gear is abutted against the gear, and when the pressing end is pressed, the driving gear is driven to rotate under the limitation of the limiting block, so that the driving wheel rotates to enable the rubber rod to move towards the discharging nozzle; when the pressing rod is loosened, the pressing rod resets, and the driving teeth overcome the torsion of the torsion spring and slide over the edge of the gear.
The hot melt glue gun is further designed in that the heating pipe is wrapped with an annular thermal resistor.
The hot melt glue gun is further designed in that the inner wall of the heating pipe is provided with fixed teeth.
The beneficial effects of the utility model reside in that:
the utility model discloses a be connected with the action wheel of gear and not link structure and carry out the propelling movement to gluing the stick, ensure that it is stable to glue the stick feeding.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a partial structure schematic diagram of the driving wheel.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the hot melt adhesive gun comprises a gun body 1, a pressing rod 2, a driving wheel 3 and a pinch roller 4, wherein the upper part of the gun body is provided with a glue stick inserting pipe 11, a heating pipe 12 and a discharging nozzle 13 which are sequentially communicated; the driving wheel is rotatably arranged in the middle of the gun body, and the upper edge of the driving wheel penetrates through the side wall of the rubber stick inserting pipe so as to be abutted against the rubber stick inserted in the rubber stick inserting pipe; the pressing wheel is rotatably arranged at the upper part of the gun body, and the lower side edge of the pressing wheel penetrates through the side wall of the rubber stick inserting pipe so as to be abutted against the rubber stick inserted in the rubber stick inserting pipe; one side of the driving wheel is coaxially connected with a gear 5 which can rotate along with the driving wheel in the middle of the gun body; the lower part of the gun body is a handle part, the pressing rod is elastically inserted into the handle part through a spring 21, and the pressing rod extends out of the handle part outwards to form a pressing end 22 outside the handle part; the part of the pressing rod, which is positioned in the handle part, is hinged with a driving gear 6, the driving gear is connected with the pressing rod through a torsion spring 7, a limiting block 8 is arranged on the pressing rod, so that the driving gear is abutted against the gear, and when the pressing end is pressed, the driving gear is driven to rotate under the limitation of the limiting block, so that the driving wheel rotates to enable the rubber rod to move towards the discharging nozzle; when the pressing rod is loosened, the pressing rod resets, and the driving teeth overcome the torsion of the torsion spring and slide over the edge of the gear.
The heating pipe is wrapped with an annular thermal resistor 9. The thermal resistance is connected with the power supply, so that when the glue stick is pushed into the heating pipe, the thermal resistance works to heat up, the glue stick melts, and the glue stick is convenient to push out from the discharging nozzle.
The inner wall of heating pipe is provided with fixed tooth 10, and the glue stick lateral wall that partly melts in the heating pipe is taken out when avoiding the action wheel to take place the reversal phenomenon in the fixed tooth of embedding.
The utility model discloses a be connected with the action wheel of gear and not link structure and carry out the propelling movement to gluing the stick, ensure that it is stable to glue the stick feeding.
