Description

Batch feeding device of injection molding machine Technical Field The utility model relates to the field of injection molding machine devices, in particular to a batch feeding device of an injection molding machine. Background The injection molding machine can make thermoplastic plastics or thermosetting plastics into plastic products with various shapes by utilizing a plastic molding die, when plastic raw materials are added into the injection molding machine, attention needs to be paid to the amount of materials put into the injection molding machine in each batch, too little hollow cavities in the cylinder of the injection molding machine can cause the cavitation of products, and if the amount of materials is too much, the machine is abnormal, so that the amount of each batch needs to be ensured to be not too much or not just right when the batches are fed in batches. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a batch feeding device of an injection molding machine, which solves the existing pain point in the field. The technical aim of the utility model is realized by the following technical scheme: The utility model provides an injection molding machine batch loading attachment, includes total hopper, divides hopper and feed hopper, total hopper divide the hopper with feed hopper from top to bottom fixed connection in proper order, total hopper bottom be provided with semicircular feed inlet with divide the hopper intercommunication, divide the hopper bottom to be provided with the opening, total hopper bottom rotates and installs rotatory apron, rotatory apron can cover the feed inlet, be provided with the baffle in the feed hopper, the baffle can cover divide hopper bottom opening, divide hopper bottom fixed mounting to have the guide arm, the vertical slidable mounting of baffle in on the guide arm, be provided with pressure sensor on the baffle. Further, the distributing hopper is rotatably provided with a rotating shaft, and the lower end of the rotating shaft is rotatably arranged at the bottom of the feeding hopper and is connected with a motor fixedly arranged at the bottom of the feeding hopper.
