A rotating rod is rotatably connected to the upper surface of the mixing tank, and a main gear is fixedly connected to the shaft. The main gears mesh with the multiple secondary gears. In this application, under the action of a second motor, through the cooperation of the rotating rod, the main gear, and the secondary gears, the multiple rotating shafts inside the mixing tank can stir and mix the raw materials inside the mixing tank through the stirring blades, thereby improving the mixing effect of the raw materials during feeding.

[0004] Although the device has many beneficial effects, the following problems still exist: there is a mixing dead zone in the three stirring blades, resulting in poor mixing efficiency; secondly, the transmission efficiency of a single auger is low, and the amplitude of the auger during long-distance transmission increases, causing vibration damage to the mechanical structure of the feeding device.

A support component 300 is provided at the bottom of the transmission tank 210, which includes a bracket 310, a base 320, a disc spring assembly 321, and a damping pad 350.

[0036] It is worth noting that, in order to mix and stir the materials fed into the injection molding machine, the mixing assembly 100 specifically includes a mixing tank 110. A partition 111 is embedded in the inner circumference of the mixing tank 110 to separate the drive chamber and the mixing chamber. A driven gear 122 is rotatably connected to the top of the partition 111, and a main gear meshes with the outer circumference of the driven gear 122. A motor 120 is fixedly connected to the top of the main gear, and a stabilizer is fixedly connected to the bottom of the motor 120 to ensure the stability of the motor 120 during operation.

A rotating shaft 130 is fixedly connected to the bottom. Six scrapers 140 are welded to the top of the outer circumference of the rotating shaft 130 to scrape off the adhering layer on the inner circumference of the mixing tank 110 and break up the mixing dead corners.

[0038] Meanwhile, in order to support the transmission tank 210, specifically, the support assembly 300 includes a base plate 330, with a damping pad 350 fixedly connected to the bottom of the base plate 330. The damping pad 350 is made of polyurethane and is used to block vibration transmission. Multiple bases 320 are welded to the top of the base plate 330. A connecting groove is opened on the top of the base 320. Two disc spring assemblies 321 are fixedly connected to the bottom of the inner cavity of the connecting groove to absorb vibration energy. A bracket 310 is inserted into the inner side wall of the connecting groove. The bottom of the bracket 310 is in close contact with the disc spring assembly 321. The disc spring assembly 321 refers to a disc spring.

[0039] Furthermore, to improve the mixing effect of the materials, specifically, the top of the outer circumference of the mixing tank 110 is connected to the feed frame 112 for feeding the injection molding materials, the scraper 140 is installed at an angle of 45 degrees to facilitate the natural fall of the materials after scraping, the stirring blade 150 has a spiral structure to facilitate the mixing of materials to form a mixing vortex, and the shearing blade 160 has a crescent-shaped structure to facilitate the shearing of clumps of materials.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The injection molding feeding device of this embodiment is used in the following specific process:

[0044] 1. Plastic is fed into the mixing tank 110 through the feed frame 112. Then, the motor 120 is started by the button 121. The motor 120 drives the main gear to rotate. The driven gear 122, which meshes with the outer wall of the main gear, drives the rotating shaft 130 to rotate. The rotating shaft 130 then drives the scraper 140, the stirring blade 150 and the shearing blade 160 to rotate. The scraper 140 scrapes off the material adhering layer on the top of the inner wall of the mixing tank 110. Then, the stirring blade 150, together with the three rib rings 113, mixes and stirs the material. Finally, the material falls naturally and is shredded by the shearing blade 160. Then, it is discharged from the mixing tank 110 into the transfer tank 210.

[0045] 2: After the material is discharged from the mixing tank 110 into the transfer tank 210, the motor 340 is started by the button 2 342. Then the motor 340 drives the transmission disc 341 to rotate, which in turn drives the synchronous disc 221 to rotate with the transmission belt 222. Then the synchronous disc 221 drives the auger 220 to rotate and transfer the material. The three ribs 211 help to improve the material transfer efficiency. Then the discharge pipe 230 is connected to other processing equipment or storage containers, and the material discharge is controlled by the manual valve 231.

[0046] 3: When the auger 220 inside the transfer tank 210 is running, the transfer tank 210 will generate mechanical vibration. The mechanical vibration is then transmitted through the bracket 310 and the vibration energy is absorbed by the disc spring assembly 321. The remaining vibration energy is transmitted to the base plate 330 through the base 320 and finally blocked by the damping pad 350.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
