Description

Technical Field

[0001] The utility model relates to the technical field of rugby production, in particular to an automatic feeding mechanism of an internal mixer. Background Art

[0002] Closed rubber mixer is also called internal mixer. It is mainly used for plasticizing and mixing rubber. It is mainly composed of internal mixer, rotor, rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base. It is used in the production of rugby.

[0003] Chinese patent publication number CN218196194U proposes "an internal mixer with an automatic feeding mechanism for rubber blocks". The technical solution proposes the problem that "the existing internal mixers require manual feeding operations on rubber blocks when plasticating and mixing rubber blocks, which increases manpower input and greatly reduces work efficiency, and is not conducive to practical application and operation". The utility model provides the following technical solution: "The servo motor drives the disc to rotate and the connecting rod to rotate at the same time. The connecting rod is used to connect the disc and the push block, thereby driving the push block to slide along the top of the operating table, thereby pushing the rubber block from the inside of the square cylinder to the inside of the internal mixer."

[0004] The above device has the following defects in actual use: when the push block moves to the right side of the square cylinder, the rubber blocks inside the square cylinder will automatically fall from the discharge port into the discharge hopper and enter the internal mixer, making it difficult to accurately control the amount of added rubber blocks. Therefore, an automatic feeding mechanism of the internal mixer is proposed to solve the above problem. Utility Model Content

A material transfer auger 9 that penetrates the transverse tube 6 and the steel cylinder 7 is fixedly installed on the output end of the DC motor 8. The material transfer auger 9 has a diameter smaller than the inner diameter of the transverse tube 6. The material transfer auger 9 is rotatably connected to the inner side wall of the steel cylinder 7.

[0025] The quantity control structure includes a transparent measuring cylinder 11 fixedly mounted on the bottom of the steel cylinder 7. The top and bottom of the transparent measuring cylinder 11 are through structures. The transparent measuring cylinder 11 is through-connected with the steel cylinder 7. The rubber raw material entering the steel cylinder 7 directly falls into the transparent measuring cylinder 11. At this time, the outside world can clearly observe the amount inside the transparent measuring cylinder 11.

[0026] The working principle of the above embodiment is:

[0027] During use, the rubber raw material used for making rugby balls inside the raw material holding tube 4 falls into the inside of the transverse tube 6 through the vertical tube 5. At this time, the DC motor 8 drives the material conveying auger 9 to rotate to bring the rubber raw material inside the transverse tube 6 into the inside of the steel cylinder 7. The rubber raw material entering the steel cylinder 7 directly falls into the inside of the transparent measuring cylinder 11. At this time, the outside world can clearly observe the amount inside the transparent measuring cylinder 11. When the amount of raw materials inside the transparent measuring cylinder 11 is suitable, the DC motor 8 can be controlled to stop running. At this time, the raw materials inside the transverse tube 6 cannot enter the inside of the steel cylinder 7. Then, the servo motor 13 drives the blocking plate 15 at the bottom of the transmission rod 14 to rotate in the opposite direction to unblock the bottom of the transparent measuring cylinder 11. At this time, the raw materials inside the transparent measuring cylinder 11 automatically fall into the inside of the internal mixer body 2 for processing. Finally, the servo motor 13 drives the blocking plate 15 to rotate in the opposite direction to reset it so that the bottom of the transparent measuring cylinder 11 can be blocked.
