[0002] Plastic pellets are a type of granular material made from plastic raw materials. They are widely used in various processing techniques, such as injection molding, extrusion molding, and blow molding, to manufacture various plastic products.

[0003] Injection molding, also known as injection molding, is a plastic processing method. Its basic principle is to add plastic raw materials into the injection machine, melt them by heating, inject them into the mold through the nozzle of the injection machine, and then cool and solidify to obtain the molded product.

When the waste is in the waste box, the injection molding machine needs to be stopped, and the operator enters the injection molding machine to take out the waste box. This process of entering the injection molding machine to recycle waste has safety hazards and low work efficiency. When using the injection molding device, the plastic pellets are put into the injection tube of the injection molding machine body 4 through the feed port, the injection molding machine body 4 is opened to melt the plastic pellets, and then the motor 17 is started. The motor 17 drives the screw 16 to rotate, and the screw 16 drives the slide 3 to move through the slider 15. The slide 3 drives the injection port of the injection molding machine body 4 to disengage from the injection mold 19 feed hole. At this time, the injection tube slides on the upper part of the slot of the collection tank 10 until the injection port of the injection tube moves above the collection tank 10. The injection molding machine body 4 discharges the waste through the injection port, and then drops it into the drawer 12 at the bottom of the collection tank 10. After the waste is discharged, the cylinder 6 is started to drive the scraper 8 to scrape the waste on the injection port, and then the drawer 12 is pulled out to clean the waste inside.

The slider 15 is slidably mounted on the screw 16 through the threaded hole; during operation, when the injection molding device is used, the screw 16 is rotated, and the slider 15 drives the slider 15 to move under the action of the thread on the screw 16, and the slider 15 drives the slide 3 to move, and the slide 3 drives the injection port of the injection molding machine body 4 to separate from the injection hole of the injection mold 19 until the injection port moves to above the collecting tank 10.

[0024] A motor 17 is fixedly mounted on one side of the fixing seat 18, and the front end of the rotating shaft of the motor 17 is fixedly connected to one end of the screw 16; during operation, when the injection molding device is used, the motor 17 is started, and the motor 17 drives the screw 16 to rotate, and the screw 16 drives the injection molding machine body 4 to separate from the injection mold 19 to discharge the waste into the collection tank 10.

[0025] A cylinder 6 is fixedly installed on the top of the bracket 5, and the front end of the piston rod of the cylinder 6 passes through the top plate of the bracket 5 and extends to the top of the injection molding machine body 4. A knife holder 7 is fixedly installed on the front end of the piston rod of the cylinder 6, and a scraper 8 is fixedly installed in the knife holder 7. During operation, when the injection molding device is used, when the injection port of the injection cylinder of the injection molding machine body 4 moves to above the collecting tank 10, the cylinder 6 is started, and the cylinder 6 pushes the knife holder 7 to drive the scraper 8 to move toward the outlet end of the injection port, scraping off the molten plastic sticking to the injection port and dropping it into the drawer 12.

[0026] Springs 14 are provided between the two sides of the bottom of the slide 9 and the base 1, and protective cylinders 13 are fixedly installed on both sides of the bottom of the slide 9, and the protective cylinders 13 are sleeved on the outside of the springs 14; during operation, when the injection molding device is used, the injection molding machine body 4 slides, and the notch of the collection tank 10 contacts the lower part of the injection tube of the injection molding machine body 4, and the spring 14 is in a compressed state. When the injection port of the injection tube moves to above the collection tank 10 and directly below the scraper 8, the injection molding machine body 4 discharges waste. During this process, the spring 14 stretches, driving the collection tank 10 to rise so that the collection tank 10 rises to the lower part of the injection port.

[0027] A slide rail 11 is fixedly installed at the bottom of the collection tank 10, and the drawer 12 is slidably installed in the slide rail 11; during operation, when the injection molding device is used, the waste material in the early stage of injection molding is collected in the drawer 12, and the drawer 12 is pulled out of the collection tank 10 through the slide rail 11, and then the waste material in the drawer 12 is classified and processed.

[0028] Working principle: At present, the injection molding machine can only make the waste fall into the waste box below the injection molding machine. The injection molding machine needs to be stopped and the operator enters the injection molding machine to take out the waste box. This process of entering the injection molding machine to recycle waste has safety hazards and low work efficiency. When using the injection molding device, the plastic pellets are put into the injection tube of the injection molding machine body 4 through the feed port, the injection molding machine body 4 is turned on to melt the plastic pellets, and then the motor 17 is started. The motor 17 drives the screw 16 to rotate, and the screw 1 6 drives the slide 3 to move through the slider 15, and the slide 3 drives the injection port of the injection molding machine body 4 to separate from the feed hole of the injection mold 19. At this time, the injection tube slides on the upper part of the notch of the collection tank 10 until the injection port of the injection tube moves above the collection tank 10. The injection molding machine body 4 discharges the waste through the injection port, and then drops it into the drawer 12 at the bottom of the collection tank 10. After the waste is discharged, the cylinder 6 is started to drive the scraper 8 to scrape the waste on the injection port, and then the drawer 12 is pulled out to clean the waste inside.
