Problems solved by technology
The injection molding machine injects plastic particles into the required shape in the mold through high pressure. Currently, the large injection molding machines on the market have a higher hopper position, so when feeding plastic particles to the injection molding machine, a lifting device or manual feeding is required, and the feeding efficiency is relatively low. Low

Embodiment Construction
[0009] Such as figure 1 As shown, it is an embodiment of a feeding device for an injection molding machine of the present invention, including a raw material tank 1, a pneumatic conveying mechanism 2 and a conveying hose 3, the discharge port of the raw material tank 1 is connected to the pneumatic conveying mechanism 2, and the pneumatic conveying The mechanism 2 transports raw materials to the hopper 4 of the injection molding machine through the transport hose 3 . The hopper 4 of the injection molding machine is equipped with a raw material metering sensor 5 to measure the amount of raw materials in the hopper. Once the raw material metering sensor 5 detects the lack of material, the information will be fed back to the pneumatic conveying mechanism 2 through the signal line 6, and the pneumatic conveying mechanism 2 will start Convey raw materials.

The invention discloses a charging device for an injection molding machine, comprising a raw material tank, a pneumatic transmission mechanism and a transmission hosepipe, wherein the discharging hole of the raw material tank is connected with the pneumatic transmission mechanism; the pneumatic transmission mechanism transmits raw materials from the transmission hosepipe to a charging hopper of the injection molding machine; and the charging hopper of the injection molding machine is provided with a raw material measurement sensor for measuring the amount of the raw materials in the charging hopper and feeding the raw materials information back to the pneumatic transmission mechanism in order to control the pneumatic transmission mechanism to transmit the raw materials. Because the technical scheme is adopted in the invention, the raw material tank is arranged on the ground, and the raw materials are transmitted by the pneumatic transmission mechanism to the charging hopper of the injection molding machine at a higher position via the transmission hosepipe without artificial feeding, and once the materials are insufficient, the raw materials measurement sensor feeds the material-lack information back to the pneumatic transmission mechanism, so that the pneumatic transmission mechanism can timely work to transmit the raw materials to the charging hopper of the injection molding machine.
Description
technical field [0001] The invention relates to a feeding device for an injection molding machine. Background technique [0002] At present, with the wide application of plastic products in various industries, the role of injection molding machines is increasing. The injection molding machine injects plastic particles into the required shape in the mold through high pressure. Currently, the large injection molding machines on the market have a higher hopper position, so when feeding plastic particles to the injection molding machine, a lifting device or manual feeding is required, and the feeding efficiency is relatively low. Low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a feeding device for an injection molding machine with higher feeding efficiency. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a feeding device for injection mol...
