[0023] Working principle

[0024] When a speed limit joint needs to be installed, after the operator preliminarily installs the assembly nails on the knob 5, the eight installed knobs 5 are placed in the mold 4. Subsequently, under the action of the guide plate and the positioning rod 215 near the feeding table 3, the staff first pushes the mold 4 to the initial position.

When the mold 4 reaches the positioning rod 215 near the feeding table 3, the second feeding rocker 205 resets under the action of the second spring 202 and is located between the mold 4 and the feeding table 3. After the pressing plate 206 presses the assembly nails, the positioning cylinder 213 near the discharging seat 1 is activated, and the positioning rod 215 moves downward. Subsequently, the first transfer cylinder is activated, which drives the first moving block 211 to move, and then drives the first feeding rocker 204 to move, thereby pushing the pressed mold 4 to move, and further pushing the pressed mold 4 into the internal limiting component. Subsequently, the first transfer cylinder resets, and the first feeding rocker 204 resets. Then, the positioning cylinder 213 near the discharging seat 1 is activated in the reverse direction, and the positioning rod 215 moves upward; the positioning cylinder 213 near the feeding table 3 is activated, and the positioning rod 215 moves downward. Then, the second transfer cylinder 201 is activated, which drives the second feeding rocker 205 to move, thereby driving the next mold 4 to move into the positioning rod 215 near the discharging seat 1, and further completing the automatic feeding of the next mold 4. Therefore, the present utility model realizes the continuous feeding of the mold 4 while extruding eight knobs 5 at a time, thereby improving the working efficiency.
