[0023] The vertical telescopic rod 15 is an electric push rod or a hydraulic rod.

[0024] The feed conveyor 5 is equipped with a loading assembly, which includes a portal frame 7 and a mechanical claw. The portal frame 7 is fixed to the loading end of the feed conveyor 5. The top of the portal frame 7 is provided with a horizontal elongated through hole 20. A screw 21 is provided in the elongated through hole 20. The two ends of the screw 21 are rotatably connected to the two ends of the elongated through hole 20 via bearings.

[0028] The horizontal telescopic rod 25 is an electric push rod or a hydraulic rod.

[0029] Working principle: the material transport trolley transports the stacked rubber blocks to the bottom of the gantry, the forward and reverse motors rotate to make the mechanical claw move to the top of the material transport trolley, then the vertical telescopic rod 2 extends, the mechanical claw moves down, grabs the rubber block at the top of the material transport trolley, and then the vertical telescopic rod 2 contracts, driving the rubber block to move up, the forward and reverse motors rotate in the opposite direction, moving the rubber block fixed by the mechanical claw to the top of the belt conveyor and placing the rubber block on the belt conveyor. The belt conveyor transports the rubber block to the dust removal chamber. Under the action of the negative pressure generated by the fan, the dust on the belt conveyor and the dust on the rubber block can be sucked away, which has a dust removal effect on the rubber block. The dust-removed rubber block enters the feed barrel through the guide plate. By controlling the frequency of the mechanical claw continuously placing the rubber block on the belt conveyor and the conveying speed of the belt conveyor, the rubber block can be evenly entered into the internal mixer body. At the same time, when multiple rubber blocks enter the feed barrel, the vertical telescopic rod extends, causing the push plate to move down and push the rubber block into the internal mixer body to avoid rubber blocks from being blocked at the feed inlet. The feeding process ensures uniform feeding without affecting the normal operation of the internal mixer. At the same time, the degree of automation is high, which saves labor costs and improves production efficiency and production quality.
