Description

Fire hydrant core conveyer Technical Field The utility model relates to the technical field of fire hydrant production equipment, in particular to a fire hydrant core conveyor. Background The casting is a processing mode that solid metal is melted into liquid and poured into a casting mold with a specific shape, and when the solid metal is solidified and formed, in the casting production of a fire hydrant, the core-out temperature is as high as 180-350 ℃, and in the past, a manual hand-held wood board is generally adopted to connect the core, but the surface of the core is easy to be bumped, and the temperature of a core part is too high, so that the damage to a human body is also easy to be caused; Therefore, a conveyor with a lifting function is generally adopted for carrying, but a common conveyor belt is easy to age and deform rapidly at high temperature, and the impact during blanking of a mold core can accelerate the local abrasion of the conveyor belt, so that the conveyor belt needs to be replaced frequently. Disclosure of utility model Accordingly, in view of the above-described problems, the present utility model proposes a hydrant core conveyor. In order to achieve the aim, the technical scheme of the utility model provides a hydrant core conveyor which comprises a rack, a lifting device arranged on the rack, a driving roller arranged on the rack through a first driving device, a driving roller arranged on the rack, and a composite conveying belt arranged between the driving roller and the driving roller, wherein the composite conveying belt comprises a driving belt arranged between the driving roller and the driving roller, a plurality of high-temperature-resistant silica gel foam blocks arranged on the driving belt, and Teflon belts arranged on the high-temperature-resistant silica gel foam blocks through a guiding and positioning device, and the high-temperature-resistant silica gel foam blocks are in a shape of bar ribs and are uniformly and intermittently arranged along the conveying direction; The guide positioning device comprises a plurality of guide through holes formed in the high-temperature-resistant silica gel foam block and a plurality of guide columns matched with the guide through holes and formed in the Teflon belt, and the depth of the guide through holes is larger than the height of the guide columns.
