Description

Technical Field

[0001] The utility model relates to the technical field of furnace rollers, in particular to a furnace roller which is convenient for protecting the shaft end. Background Art

[0002] Existing furnace roller technologies mostly work by directly fixing the shaft end rotating shaft on both sides of the bottom end inside the furnace. However, this method is susceptible to the dual effects of thermal expansion and mechanical wear on the shaft end during use. For example, a Chinese patent discloses "a furnace roller convenient for shaft end protection", and its application number is "CN202122469744.6". It uses the rotation of the furnace roller to drive the objects processed inside the furnace for transportation. The groove can increase the friction between the furnace roller and the objects, thereby preventing the objects from sliding during transportation inside the furnace. Through the heat dissipation net and heat dissipation fan, the heat dissipation fan inside the furnace roller cavity can be used to dissipate the heat from the furnace roller body surface and the furnace roller cavity during use. However, its structure is simple and the high temperature inside the furnace roller can easily affect the fan motor and cause safety accidents. Utility Model Content
