All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an injection molding machine barrel facilitating feeding, including a barrel body 1 and a barrel cover 2. A discharge pipe 5 is connected to the bottom of the barrel body 1. A feeding port 6 is opened at the top of the barrel cover 2. A triangular plate 9 is fixedly installed at the bottom of the barrel body 1. Driven gears 7 are rotatably installed at the bottoms of the three corners of the triangular plate 9. Stirring rods 10 are fixedly installed at the bottoms of the driven gears 7. A driving gear 8 is rotatably installed at the bottom of the center of the triangular plate 9. A rotating rod 11 is fixedly installed at the bottom of the driving gear 8. Stirring blades 14 are fixedly installed on the outer side of the rotating rod 11. A connecting rotating column 12 is fixedly installed at the bottom of the rotating rod 11. A spiral pushing rod 13 is fixedly installed at one end of the connecting rotating column 12 away from the rotating rod 11. A driving motor 4 is fixedly installed at the top of the barrel cover 2. Bearings are fixedly installed inside the centers of the barrel cover 2 and the driving gear 8. The output end of the driving motor 4 penetrates through the bearings inside the barrel cover 2 and the driving gear 8 and is fixedly connected to the top of the rotating rod 11. The barrel cover 2 is sleeved on the top of the barrel body 1, and the stirring rods 10, the rotating rod 11, the connecting rotating column 12, and the spiral pushing rod 13 are all located inside the barrel body 1. The spiral pushing rod 13 is located inside the discharge pipe 5.

[0022] The working principle of the above technical solution: Injection molding materials can be added into the barrel body 1 through the discharge pipe 5, which is convenient and fast. In addition, the driving motor 4 can be started. The output end of the driving motor 4 can drive the driving gear 8 to rotate, and then drive the spiral pushing rod 13 to rotate through the connecting rotating column 12, so that the injection molding materials inside the barrel body 1 can be pushed out through the discharge pipe 5 into the injection molding machine. The feeding of the injection molding machine is simple and convenient. The use of the spiral pushing rod 13 for conveying can stably convey the materials from the barrel body 1 to the inside of the injection molding machine, simplifying the feeding process. In addition, when the driving gear 8 rotates, it can drive the three driven gears 7 to rotate, and then drive the three stirring rods 10 to rotate, so as to stir the injection molding raw materials inside the barrel body 1, prevent the injection molding raw materials from coagulating, facilitate subsequent feeding of the injection molding machine, prevent material blockage, and improve production efficiency.

[0023] In another embodiment, as Figures 1 - 5 shown, there are three feeding ports 6, and sealing plugs 3 are clamped and installed inside the three feeding ports 6.

[0024] Through the three feeding ports 6 provided, injection molding raw materials can be simultaneously injected into the interior of the cylinder body 1, improving the feeding efficiency. Additionally, through the plug 3 provided, the feeding port 6 can be blocked to prevent sundries from entering the interior of the cylinder body 1 through the feeding port 6.

[0025] In another embodiment, as Figures 1 - 5 shown, a driven gear ring 15 is rotatably installed inside the cylinder body 1. Four scraping plates 16 are fixedly installed on the driven gear ring 15, and one end of each scraping plate 16 is in contact with the inner wall of the cylinder body 1. The outer side of the driving gear 8 meshes with the outer side of the driven gear 7, and the outer side of the driven gear 7 meshes with the inner side of the driven gear ring 15. An annular groove 17 is formed inside the cylinder body 1. A rotating ring 18 is fixedly installed on the outer side of the driven gear ring 15, and the rotating ring 18 is movably installed inside the annular groove 17.

[0026] When the driven gear 7 rotates, it can drive the driven gear ring 15 to rotate, and enable the rotating ring 18 to rotate inside the annular groove 17, so that the rotating ring 18 drives the scraping plate 16 to rotate inside the cylinder body 1, thereby enabling the scraping plate 16 to scrape the inner wall of the cylinder body 1, preventing the injection molding raw materials from adhering to the inner wall of the cylinder body 1, and improving the quality of injection molding.

[0027] Working principle: Injection molding materials can be added into the interior of the cylinder body 1 through the discharge pipe 5, which is convenient and fast for adding. Additionally, the driving motor 4 can be started. The output end of the driving motor 4 can drive the driving gear 8 to rotate, thereby driving the spiral pushing rod 13 to rotate through the connecting rotating column 12. Thus, the injection molding materials inside the cylinder body 1 can be pushed out through the discharge pipe 5 into the interior of the injection molding machine, which is simple and convenient for feeding the injection molding machine. Using the spiral pushing rod 13 for conveying can stably convey the materials from the cylinder body 1 to the interior of the injection molding machine, simplifying the feeding process. Additionally, when the driving gear 8 rotates, it can drive the three driven gears 7 to rotate, thereby driving the three stirring rods 10 to rotate, so as to stir the injection molding raw materials inside the cylinder body 1, prevent the injection molding raw materials from coagulating, facilitate subsequent feeding of the injection molding machine, prevent material blockage, and improve production efficiency. When the driven gear 7 rotates, it can drive the driven gear ring 15 to rotate, and enable the rotating ring 18 to rotate inside the annular groove 17, so that the rotating ring 18 drives the scraping plate 16 to rotate inside the cylinder body 1, thereby enabling the scraping plate 16 to scrape the inner wall of the cylinder body 1, preventing the injection molding raw materials from adhering to the inner wall of the cylinder body 1, and improving the quality of injection molding.
