An extrusion device

Abstract

The present invention discloses a material extrusion device. The structural design of the present invention is reasonable. The photoelectric sensor is electrically connected to the driving device, so that when the photoelectric sensor detects the front end of the material on the material receiving platform, the photoelectric sensor sends a control instruction to the driving device, and then the driving device drives the rotating rod to rotate. The rotating rod drives the cutter to cut the material output forward from the discharge hole. At the same time, the rotating rod drives the pushing part to push the material on the material receiving platform to the inclined sliding plate. Under the action of gravity, the material on the inclined sliding plate slides down to the conveyor belt, and the conveyor belt can carry the material forward to the subsequent processing station or the material receiving station. The length difference of the cut materials is reduced, thereby reducing the weight difference between the cut materials, so as to meet the needs of customers. In addition, while continuously feeding the material to the feed port, the material can be continuously discharged, cut, pushed, and conveyed, thereby speeding up the work efficiency.

Function: The photoelectric sensor is electrically connected to the drive device, so that when the photoelectric sensor detects the front end of the material on the receiving platform, the photoelectric sensor sends a control command to the drive device, and then the drive device drives the rotating rod to rotate, and the rotating rod drives the cutter to cut the material output forward from the discharge hole. At the same time, the rotating rod drives the pusher to push the material on the receiving platform to the inclined slide plate. Under the action of gravity, the material on the inclined slide plate slides down to the conveyor belt, and the conveyor belt can carry the material forward to the subsequent processing station or the receiving station. From the above analysis, it can be seen that since the photoelectric sensor will only send a control command to the drive device when it detects the front end of the material on the receiving platform, the cutter and the pusher will not be affected by the discharge speed of the extruder, thereby reducing the difference in the length of the cut material, thereby reducing the weight difference between the cut materials, thereby meeting the needs of customers.
