[0023] Example: Reference Figure 1-4 The shown device is a quantitative feeding device for the production of ASA plastic film, comprising a hopper 1. A screen 2 for filtering plastic particles is provided on the top of the hopper 1. In order to prevent the agglomerated plastic particles from being unable to be used normally and thus causing blockage, a rubbing mechanism for rubbing the agglomerated particles is provided on the screen 2, and a quantitative mechanism for quantitatively feeding particles is provided in the lower half of the hopper 1. The quantitative mechanism and the rubbing mechanism are connected by a linkage mechanism, thereby achieving the purpose of multiple uses of one machine.

[0024] A mounting member 4 is provided below the screen 2. The mounting member 4 is bolted through the holes on the screen 2 and fixed with nuts. A support rod 3 is installed on the inner wall of the hopper 1 and connected to the mounting member 4 to achieve further structural fixation and enhance structural strength. Interconnected holes are provided on the mounting member 4 and the screen 2. The rubbing mechanism is provided on the mounting member 4 and passes through the above-mentioned holes. Driven by the linkage mechanism, the agglomerated particles above the screen 2 are rubbed loose.

[0025] Scattering mechanism: The inner bottom surface and inner top surface of the mounting member 4 are respectively connected to the No. 1 bevel gear 5 and the No. 2 bevel gear 8, which are connected by rotating the driving gear 11 (the driving gear 11 is also a bevel gear) on the inner wall of the mounting member 4. The connecting rod 12 is connected to the driving gear 11 to achieve the purpose of driving the No. 1 bevel gear 5 and the No. 2 bevel gear 8 to rotate. A reversing rod 9 is provided on the No. 2 bevel gear 8 which is coaxial with the reversing rod 9. There are through holes on the bevel gear 8, and the forward rotating rod 6 rotating in the through hole is coaxially connected to the No. 1 bevel gear 5. The above structures cooperate with each other to achieve the purpose of opposite rotation between the reverse rod 9 and the forward rotating rod 6. Three groups of No. 2 rotating rods 10 and No. 1 rotating rod 7 are respectively provided on the reverse rod 9 and the forward rotating rod 6. The No. 1 rotating rod 7 is U-shaped. During the rotation process, the No. 2 rotating rod 10 passes through the U-shaped groove of the No. 1 rotating rod 7, and the latter cooperates to rub off the agglomerated particles so that they can pass through the holes in the screen 2.

[0026] Quantitative mechanism: The rotating shaft 16 is rotatably connected to the inner wall of the lower part of the hopper 1, and the quantitative plates 17 fixed on its outer wall by bolts are slidably connected to the inner wall of the hopper 1. Six groups of quantitative plates 17 are used to achieve quantitative delivery of plastic particles.

[0027] Linkage mechanism: In order to improve the linkage of the structure and enhance the utilization rate of the motor, a coaxial No. 1 synchronous wheel 13 and a No. 2 synchronous wheel 15 are respectively provided on the connecting rod 12 and the rotating shaft 16. The two are connected by a synchronous belt 14. Under the drive of the motor, the No. 2 synchronous wheel 15 is controlled to rotate, thereby controlling the use of the rubbing mechanism and the quantitative mechanism.

[0028] The utility model works as follows: the material is put into the hopper 1 from the top, and then the motor is started. The motor drives the second synchronous wheel 15 of the linkage mechanism to rotate. The rotating No. 2 synchronous wheel 15 drives the No. 1 synchronous wheel 13 to rotate through the synchronous belt 14, thereby controlling the rotation of the connecting rod 12 and the rotating shaft 16. The rotating rotating shaft 16 controls the quantitative plate 17 to rotate inside the hopper 1 to achieve quantitative material distribution; in the process of the rotation of the connecting rod 12, it drives the driving gear 11 on the inner wall of the mounting member 4 to rotate, and the rotating driving gear 11 drives the No. 1 bevel gear 5 and the No. 2 bevel gear 8 meshed therewith to rotate in the opposite direction, and the No. 1 bevel gear 5 drives the forward rotating rod 6 to rotate in the through-hole of the No. 2 bevel gear 8 and the reversing rod 9, thereby controlling the No. 1 rotating rod 7 provided on the forward rotating rod 6 to rotate forward. At the same time, the reversing rod 9 coaxial with the No. 2 bevel gear 8 controls the No. 2 rotating rod 10 to reverse, and cooperates with the No. 1 rotating rod 7 to achieve the purpose of breaking up the agglomerated particles, so that the plastic particles can pass through the holes of the screen 2.
