[0017] The automatic feeding equipment for producing plastic products according to the present invention will be further described in detail below through specific embodiments.

[0018] like Figure 1-4 As shown, an automatic feeding device for the production of plastic products includes a support plate 1, a plastic storage barrel 2 is provided on the left side of the support plate 1, a fixed plate 3 is fixedly connected to the left side of the support plate 1, and a vacuum generator 4 is fixedly installed on the left side of the fixed plate 3. The vacuum generator 4 is a new type of vacuum component that uses a positive pressure gas source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure in places where compressed air is available or in places where positive and negative pressures are required at the same time in a pneumatic system. The vacuum generator 4 is widely used in industrial automation in the fields of machinery, electronics, packaging, printing, plastics and robots. The working principle of the vacuum generator 4 is to use a nozzle to spray compressed air at high speed. Gas forms a jet at the nozzle outlet, generating a suction flow. Under the suction effect, the air around the nozzle outlet is continuously sucked away, so that the pressure in the adsorption chamber drops below the atmospheric pressure, forming a certain vacuum degree. The input end of the vacuum generator 4 is fixedly connected with a feed pipe 19, and the bottom end of the feed pipe 19 extends to the inside of the plastic storage barrel 2. The output end of the vacuum generator 4 is fixedly connected with a telescopic hose 5, and the top end of the telescopic hose 5 is fixedly connected with a feeding pipe 6.

Through the setting of the bearing seat 10, the externally threaded rotating rod 8 can be installed, which will make the externally threaded rotating rod 8 rotate more stably.

The bottom surface of the support plate 1 is fixedly connected to a base 18, and the bottom surface of the plastic storage barrel 2 is fixedly connected to a plurality of supporting legs 14. Through the cooperation of the limiting groove 12 and the limiting block 11, the internal thread lifting seat 9 and the feeding tube 6 can be stably lifted and lowered. The discharge port 15 can be used to discharge the plastic particles inside the plastic storage barrel 2, which is convenient for cleaning when the plastic particles are replaced. The connection between the support plate 1 and the plastic storage barrel 2 can be deepened by the fixing block 17, and the device can be stably supported by the supporting legs 14 and the base 18.

[0021] The working principle of the utility model is: firstly, the device is installed in a suitable position, and the feeding tube 6 is located above the injection hopper at the top of the injection molding machine; then, the PLC controller 13 is used to start the driving motor 7 to run clockwise, which can drive the external threaded rotating rod 8 to fit the internal thread of the internal threaded lifting seat 9 in a clockwise manner, and the feeding tube 6 will be driven to move downward through the internal threaded lifting seat 9, and the bottom end of the feeding tube 6 will be dropped to the inside of the injection hopper at the top of the injection molding machine; then, the plastic particles are injected into the inside of the plastic storage barrel 2, and then the vacuum generator 4 is started to work, which can suck the plastic particles inside the plastic storage barrel 2, and then transport them through the telescopic hose 5, and finally injected into the inside of the injection hopper at the top of the injection molding machine through the feeding tube 6, and the plastic particles can be continuously fed.
