Disposal module for used waste suction heads on instrument

Abstract

The utility model provides a processing module for waste suckers after use on an instrument, which comprises a main support, a collecting tank, a tooth-shaped cutter, a heating ring, a driving device, a transmission mechanism, a detection device and a sucker entering device, the detection device is arranged at the input end of the sucker entering device, a guide groove is arranged in the sucker entering device, and the tooth-shaped cutter is arranged in the guide groove. The output end of the guide groove communicates with the input end of the heating ring, the output end of the heating ring is connected with the input end of the tooth-shaped cutter, and the output end of the tooth-shaped cutter is connected with the input end of the collecting groove. According to the utility model, waste suckers discarded after being used on an instrument are treated by adopting a method of combining heating softening and crushing, so that the problem that the whole waste suckers occupy more space of a garbage box is solved, the occupied space of the discarded suckers can be effectively reduced, the bagging capacity is increased after the waste suckers are crushed, and the waste suckers are prevented from being damaged. And the frequency that an operator dumps sucker waste in the experiment work can be reduced, and the convenience and the environmental protection safety during waste collection can be improved.
