Description

Technical Field

[0001] This utility model relates to the field of vacuum filling technology, and in particular to a separate vacuum filling machine for injection molding machines. Background Technology

[0002] Chinese patent document CN222117696U discloses a separate vacuum packing machine, including a hopper and a fixed cylinder. A vacuum pump is fixedly installed on the outer wall of the hopper, with an exhaust pipe fixedly installed at the exhaust end and an exhaust pipe fixedly installed at the exhaust end. An elastic filter screen is fixedly installed at one end of the fixed cylinder. A striking mechanism is provided inside the fixed cylinder, including striking rods. A return spring is elastically connected between the striking rods and the fixed cylinder. A drive motor is fixedly installed on one side of the inner wall of the fixed cylinder. A rotating shaft is rotatably connected to the inner side wall of the fixed cylinder near the striking rods. By driving the two striking rods through the drive motor, the two striking rods effectively strike the elastic filter screen, thereby achieving the purpose of cleaning the elastic filter screen. This not only improves energy utilization but also saves on the operating costs of the device and ensures the effectiveness of the elastic filter screen during use.

[0003] The material output of a separate vacuum filling machine relies on gravity and pressure difference, and is set up independently. However, these machines, including some existing vacuum filling machines, are small in size and relatively short in height compared to the equipment requiring filling. The material needs to be conveyed upwards within the pipe, resulting in slow material conveying speed and a tendency for incomplete conveying and material residue. Therefore, we propose a separate vacuum filling machine for injection molding machines. Utility Model Content

Through the lifting mechanism, the height of the material cylinder can be adjusted so that the material output from the discharge pipe is higher than the equipment to be filled, i.e. the injection molding machine hopper, ensuring the smoothness of material conveying. This solves the problem that some existing vacuum filling machines are small in size and relatively short in height compared to the equipment to be filled, requiring the material to be conveyed upward in the pipe, resulting in slow material conveying speed and easy incomplete conveying and residual material. This improves the practicality of the filling machine.

[0017] (2) The injection molding machine uses a separate vacuum filling machine. Through the stirring mechanism, the material can be stirred during the output to prevent jamming and ensure the stability of material conveying. At the same time, under the action of the filter box and filter plate, the filter plate can be quickly disassembled and cleaned, ensuring the effect of the filling machine and facilitating the promotion and use of the filling machine.
