Description

Technical Field

[0001] This utility model relates to the field of raw material tape production technology, specifically to an automatic cutting device for raw material tape extrusion heads. Background Technology

[0002] The feedstock (also known as "starter feed" or "transition feed") refers to the portion of material initially extruded that does not meet quality standards when the extruder starts up, due to the unstable process parameters such as temperature, pressure, and flow rate. When the feedstock is cut, the boundary point between the feedstock and the qualified product is detected by sensors.

[0003] In existing technologies, industrial cameras are generally used to capture images of the surface of raw material strips, and image processing algorithms are used to analyze the differences in features. However, the extruder generates hot air when discharging material, which contaminates the lens of the industrial camera and affects the service life of the device. Furthermore, when the cutter cuts the material head, impurities are easily attached to the cutter, which affect the cutting quality of the material head after solidification.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The connecting frame is fixed on the mounting base, the lead screw is disposed inside the connecting frame, one end of the lead screw is connected to the output shaft of the servo motor, and the guide block is disposed on the lead screw.

[0010] Preferably, the lead screw is symmetrically provided with threads at both ends, and the guide block is connected to the first protective cover and the second protective cover respectively.

The cutter is located at the bottom of the mounting plate, and the top two ends of the cleaning frame are columnar. The top of the cleaning frame passes through the mounting plate and is connected to the return spring, which is sleeved on the outside of the columnar portion of the cleaning frame.
