Abstract
Description
Technical Field
[0001] The utility model relates to a feeding device, in particular to a grinding auxiliary feeding device which is easy to convert and belongs to the technical field of PVC production equipment. Background Art
[0002] In the PVC production process, different specifications and models require ingredients of different colors. Traditionally, mixing involves large batches of a single color, which are then stored in 30-ton tanks for future use, allowing each production line to use it according to production availability, thus reducing mixing costs. However, the current market demands fast delivery of small batches of products in multiple specifications and colors. This necessitates the modification of existing equipment and processes to adapt to market demands.
[0003] According to the "subtractive color mixing principle" of toner materials, a small amount of black material can cover the blue material, but the reverse is not possible. Therefore, when continuously mixing large quantities of blue dry mix, an auxiliary feeding device is needed that can achieve fast and flexible production without affecting the rapid large-scale mixing process, thereby reducing production waste and labor costs.
[0004] Therefore, it is necessary to design a supporting equipment that can carry out auxiliary tailings and carry out small amounts of auxiliary feeding during the mixing process of large quantities of single colors by the main machine. Utility Model Content

[0031] Specifically, in this embodiment, the power output by the power distribution machine 10 drives the rotation of the second rotating shaft 14, and drives the rotation of the first rotating shaft 13, thereby causing the stirring blade 12 to rotate inside the outer cavity 11; at the same time, the second rotating shaft 14 can also transmit the power of the power distribution machine 10 to the transmission 7 for the operation of the grinding component.
[0032] Furthermore, the twin-screw feeder 5 is located at the lower side of the outer cavity 11 ; the twin-screw feeder 5 is connected to the power distributor 10 ; the power distributor 10 is disposed on the chute positioning mounting base 3 .
[0033] Specifically, the power distribution mechanism 10 distributes the power generated by the motor 8 and the speed reducer 9 through an internal gear train, thereby simultaneously driving the twin-screw feeder 5. In other words, the power distribution mechanism 10, through its internal gear train, simultaneously drives the twin-screw feeder 5, the agitator 12, and the transmission 7. The gear design of this power distribution mechanism 10 is conventional in the art, and those skilled in the art can readily obtain a similar power distribution mechanism 10.
