Description

TECHNICAL FIELD

[0001] The utility model relates to the field of recycled aluminium ingot casting, especially to a raw material feeding device for recycled aluminium ingot casting. BACKGROUND

[0002] Aluminum is a silvery white light metal with ductility, and is usually made into rod, sheet, foil, powder, strip and wire. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, and is difficult to dissolve in water. The relative density is 2.70, and the melting point is 660℃. The boiling point is 2467℃. When aluminum is produced and processed, it is usually heated and melted to form aluminum ingots of certain shapes.

[0003] When recycled aluminum ingot is cast, adding aluminum scrap halfway into the furnace will cause heat dispersion, and the furnace needs to be filled at one time. The existing raw material feeding device directly feeds aluminum scrap into the furnace, but the shape of aluminum scrap is different, which causes a large number of gaps in the furnace, reduces the utilization rate of the furnace, and cannot meet the needs of industrial production. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the problem that the existing technology directly feeds aluminum scrap, which reduces the utilization rate of the furnace, and provides a raw material feeding device for recycled aluminum ingot casting.

[0005] In order to solve the problem of the existing technology, the utility model adopts the following technical scheme:

A pair of crushing rollers are arranged inside the frame. A center shaft is fixedly arranged at the center of each crushing roller. A power mechanism is arranged on the frame to drive the crushing rollers to rotate. A distance changing assembly is arranged in the power mechanism to change the distance between the crushing rollers. A pair of first gears and a pair of second gears are arranged in the distance changing assembly. The second gears are arranged between the first gears and mesh with each other. The first gears are fixedly connected to the center shafts. An adaptive assembly is arranged on the frame to adapt to the distance changing between the crushing rollers.

[0007] Preferably, the power mechanism includes a protection box, a motor and a reducer. The protection box is fixedly arranged on one side of the frame. The motor and the reducer are arranged in the protection box. The output shaft of the motor is fixedly connected to the connecting shaft of the reducer. The output shaft of the reducer is fixedly connected to one second gear.

[0008] Preferably, the pitch-changing assembly includes a pair of first connecting rods, a second connecting rod, a fixing plate, a fixing block, a lead screw, and a knob. The pair of first connecting rods are rotatably mounted on a pair of first gears and a pair of second gears, respectively. The second connecting rod is rotatably mounted on a pair of second gears. The fixing plate is fixedly mounted on one side of the motor and reducer. The fixing block is fixedly mounted on the fixing plate through the protective box. The lead screw is rotatably mounted on the outside of the protective box. The knob is fixedly mounted on the lower end of the lead screw.

[0009] Preferably, the adapter component includes a pair of elongated slots, a pair of sliders, and a pair of elongated holes. The pair of elongated slots are all formed in the frame, the pair of sliders are slidably disposed in the pair of elongated slots, one end of the pair of central shafts is connected to the pair of sliders through bearings, the pair of elongated holes are all formed on the frame, and the other end of the pair of central shafts passes through the pair of elongated holes.

[0010] Preferably, the lower side of the frame is provided with two pairs of mounting plates by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the power mechanism drives a second gear to rotate, and the second gear drives another second gear to rotate in the opposite direction at the same speed. The pair of second gears drive a pair of crushing rollers to rotate through a pair of first gears. The crushing rollers squeeze and shear the aluminum waste in the frame, so that the aluminum waste is crushed into smaller pieces. The smaller pieces of aluminum waste fall down through the gap between the pair of crushing rollers and are directly fed into the furnace, avoiding the existence of a large number of voids in the furnace, thus increasing the utilization rate of the furnace and meeting the needs of industrial production.

[0013] 2. In this utility model, the knob drives the lead screw to rotate, and the lead screw drives the second gear connected to it to move upward through the fixed block, fixed plate, motor and reducer. One second gear drives another second gear to move upward, so that a pair of first gears move closer to the middle, thereby reducing the distance between a pair of crushing rollers, making the crushed waste aluminum material smaller, and vice versa, making the waste aluminum material larger. This allows the device to be adjusted according to actual usage needs, making it highly practical. Attached Figure Description
