Novel rubber inverting device for tire cord calendaring machine

Abstract

The invention relates to a novel rubber inverting device for a tire cord calendaring machine. The novel rubber inverting device comprises a plurality of transporting machines which are sequentially connected end to end for transporting edge rubber, and a rubber scraping part which is arranged on the first transporting machine and is used for collecting edge rubber from a roller of the calendaringmachine, wherein the output end of the last transporting machine is positioned above the input end of the next transporting machine; the rubber scraping part comprises a scraping plate which is arranged on the first transporting machine and is used for scraping edge rubber on the roller of the calendaring machine; each transporting machine comprises a transporting slot and a belt transporting mechanism arranged in the transporting slot, the belt transporting mechanism comprises two or more transmission rollers which are rotatably connected to the transporting slot, a conveyor belt which is used for sequentially connecting two or more transmission rollers, and a power device arranged on the transporting slot, and the output end of the power device is connected to one transmission roller. The novel rubber inverting device is used for collecting edge rubber on the roller of the calendaring machine, can effectively reduce vulcanized rubber particles in a product, and improves product quality.

Description

technical field [0001] The invention relates to the technical field of material recovery in the calendering process in tire production, in particular to a novel rubber-reversing device for a tire cord calender. Background technique [0002] Rubber calender is one of the basic equipment in the processing of rubber and plastic products. In rubber and plastic machinery, the calender is a heavy-duty high-precision machine. The basic structure of the rubber calender is very similar to that of the plastic calender, and the working principle is basically the same. However, since many rubber products are composite products containing cords and steel wires, the structure of the rubber calender is more complicated, the application is wider, and there are more types. The rubber calender is mainly used for the pressing of rubber materials, the hanging of textiles or steel cords, the lamination of films, the pressing of rubber embryos, and the isolation film of tire cords.

Problems solved by technology

The general treatment method is to return the produced edge glue directly to the roller or transfer it to the feeding port of the screw extruder after accumulating to a certain amount, but these two methods will affect the final product quality

[0005] The edge glue that returns directly to the roller will crush the existing film on the roller, resulting in uneven thickness distribution, and the properties of the edge glue will change after heating, and the junction with the film on the roller is prone to poor adhesion There are gaps and other defects on the surface of the product, and the edge glue that is repeatedly rolled will appear to be cured, resulting in the doping of cooked glue particles in the product, and the performance will be further reduced

[0006] The temperature of the film rises during the calendering process, and the edge glue removed from the roller will stick together, and there will be a lot of gaps inside the formed rubber ball, which may cause the product to appear hollow during the re-feeding process, although in the follow-up The hollow space in the extrusion and vulcanization process can be reduced or even disappeared, but there are still potential safety hazards during use

And when the micelles are too large, it is difficult to stuff them into the feeding port of the calender, requiring staff to observe all the time, which wastes time and energy
