Description

Technical Field

[0001] The invention relates to the technical field of polymer material production, and in particular to a full-automatic feeding mechanism for a flame retardant polymer material production line. Background Art

[0002] Polymer materials are materials composed of compounds with relatively high molecular weight. Many natural materials we come into contact with are usually composed of polymer materials, such as natural rubber, cotton, human organs, etc. The same is true for synthetic chemical fibers, plastics and rubber. Generally speaking, polymers that are widely used in life and have formed industrial production scales are called general polymer materials, and those with special uses and functions are called functional polymers.

[0003] In the process of industrial processing and production, the processing and feeding process of polymer materials is indispensable. The common mechanical feeding is to transport materials through conveyor belts and replenish materials inside the processing equipment; however, due to limited space, the inclination of the conveyor belt has to be increased, but the materials are generally granular and can easily move downward on the conveyor belt under gravity, resulting in the conveyor belt being unable to transport the polymer composite materials to the feeding port of the processing equipment. In addition, the existing automatic feeding mechanism for polymer materials has the problem of single function, which can only perform a single feeding operation and cannot mix materials.

[0004] To this end, we propose a fully automatic feeding mechanism for a flame retardant polymer material production line. Summary of the invention

[0005] The main purpose of the present invention is to provide a fully automatic feeding mechanism for a flame retardant polymer material production line, which mixes the flame retardant polymer raw materials through a stirring rod. When the stirring motor is working, two groups of first motors rotate synchronously, and the first motor drives the second threaded rod to rotate. The second threaded rod cooperates with the thread at the bottom of the vertical plate, and then drives the vertical plate and the horizontal plate to move horizontally in the material box, so that the mixing part can evenly mix the flame retardant polymer raw materials in the material box. After the flame retardant polymer raw materials are mixed, the electric cylinder pushes the push plate out of the embedded groove through the piston rod, and the push plate can push the mixed flame retardant polymer raw materials toward the direction of the discharge pipe, and the flame retardant polymer raw materials fall into the feeding assembly through the discharge pipe. The sub-raw materials fall into the feeding trough located on the feeding belt. Since the feeding component is tilted upward away from one end of the material box, it can drive the flame-retardant polymer raw materials to move upward. Through the design of the limit plate, the position of the flame-retardant polymer raw materials in the feeding trough can be limited to avoid the flame-retardant polymer raw materials from pouring out due to gravity. When the feeding trough with the flame-retardant polymer raw materials runs to the highest point of the feeding component, the flame-retardant polymer raw materials in the feeding trough will fall into the discharging piece due to inertia, and then fall into the feeding hopper at the top of the storage box through the discharging piece, thereby completing the feeding operation. By setting the blower at the bottom of the storage box, the storage box can be discharged easily, which can effectively solve the problems in the background technology.
