Internally conductive hot cut-off knife and method thereof

Abstract

The invention provides an internally conductive hot cut-off knife and a method thereof. A heat supply element and a temperature sensor are installed in the interior of a knife edge part of a knife body so that produced heat energy is acted on a knife edge directly and cutting operation is performed while hot melting is performed on the surface of a sizing material; and the heat source is installed on the knife edge part for performing the cutting operation directly, obvious heat loss is avoided without long distance heat transmission, thereby saving energy effectively. The internally conductive hot cut-off knife comprises a lower fixture body, an upper fixture body and the knife body, wherein the knife body comprises a base part clamped and fixed between the lower fixture body and the upper fixture body and the knife edge part for cutting on the surface of the sizing material; and the heat supply element for directly acting the heat energy on the knife edge and the temperature sensor which is used for connecting with an external power supply and a temperature control instrument and detecting work temperature on the surface of the knife edge are installed in the knife edge part.

Description

technical field [0001] The invention relates to a thermal cutter for cutting a rubber rubber material layer and a method thereof. Specifically, a heating component and a sensor for generating heat energy are directly arranged on a blade of a cutter body, and belong to the field of rubber machinery. Background technique [0002] Due to the popularization and use of aircraft, civil vehicles and other carriers, the level of automation and precision processing of tire manufacturing has been continuously improved. When cutting coil semi-finished products such as inner liner, sidewall or inner liner-sidewall composite parts, automatic cutting equipment is usually required to cut semi-finished products of different sizes and angles for subsequent joints, pressing, etc. In the process of use, the quality of rubber material cutting directly affects the joint and pressing between multiple materials. [0003] The thermal cutter is a type of cutter that is often used in existing automa...

AI Technical Summary

Problems solved by technology

[0008] The heat source that provides heat energy to the blade is set at the base of the cutter body. Although it is easy to install, it will cause heat loss during the heat transfer process, resulting in a large waste of energy. This is obvious in the production site of rubber layer cutting. more prominent

[0009] Thermal energy generation and temperature sensing are not set at the same or adjacent positions, which is not conducive to heat preservation and accurate temperature control, and the adoption of temperature control measures often lags behind the actual temperature situation

[0010] In order to achieve the temperature of the key parts of the cutting operation, such as the blade, an unnecessary temperature rise will be formed at the base of the cutter body and the rear parts, which will easily lead to damage and shorten the service life of the parts
