Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatic glue feeding device for an internal mixer. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is highly elastic at room temperature and can deform significantly under minimal external force, returning to its original shape upon removal of the force. The typical rubber molding process includes basic steps such as plasticizing, mixing, calendering or extrusion, molding, and vulcanization. Each step has specific product requirements and is accompanied by several auxiliary operations. To incorporate the various required compounding ingredients into the rubber, the raw rubber is first plasticized to enhance its plasticity. Carbon black and various rubber additives are then mixed with the rubber to form a rubber compound. The rubber compound is then extruded to form a shaped blank. This blank is then combined with a calendered or rubber-coated textile material (or metal material) to form a semi-finished product. Finally, vulcanization transforms the plastic semi-finished product into a highly elastic final product.

[0003] When the raw rubber is plasticized and mixed, if workers are required to load the raw film, the workers' labor intensity is high and the production efficiency is low; if ordinary conveyor belts are used for loading, there is a problem of difficulty in feeding the raw film.

This structure, which uses rollers to sizing the raw glue, is simple in structure, easy to install and manufacture, and has low maintenance costs.

[0014] Furthermore, in the aforementioned automatic glue feeding device for an internal mixer, a double-threaded screw is disposed between the pair of mounting seats. Rotation of the double-threaded screw can move the pair of roller assemblies closer together or further apart. A guide rod is also disposed between the pair of mounting seats. This structure allows the spacing between the pair of roller assemblies to be adjusted by rotating the double-threaded screw, thereby enabling the feeding device to regularly handle raw glue sheets of varying widths, thereby improving the practicality of the feeding device.
