Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing equipment, and in particular to a through-type shot blasting machine for aluminum profiles. Background Technology

[0002] Through-type shot blasting machines mainly consist of a shot blasting chamber, shot blasters, a conveying system, a shot circulation system, and a dust removal system. Its working principle is as follows: The workpiece is placed on the conveying system and fed into the shot blasting chamber. Inside the chamber, the shot blasters rotate at high speed, propelling shot (usually steel shot or cut wire) at high speed onto the workpiece surface, removing impurities such as oxide scale, rust, and welding slag. Simultaneously, this generates compressive stress on the workpiece surface, improving its fatigue strength and corrosion resistance. The propelled shot and removed impurities fall into a screw conveyor at the bottom of the chamber. The screw conveyor transports the shot to the bottom of an elevator, which then lifts it to a separator. The separator separates the shot from the impurities; the clean shot is recycled back into the shot blasters, while the impurities are discharged from the system. During the shot blasting process, the dust removal system uses a fan to draw dust-laden gas into a dust collector. After filtration through filter bags, the dust is collected, and the purified gas is released into the atmosphere. Existing shot blasting machines typically have shot blasters installed on the same plane to simultaneously blast the surface of aluminum profiles. However, due to the diverse external structures and shapes of aluminum profiles, there may be certain shot blasting dead zones on the surfaces of different aluminum profiles. In view of the above situation, this utility model provides a shot blasting device. Utility Model Content

[0003] The purpose of this invention is to provide a through-type shot blasting machine for aluminum profiles.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A through-type shot blasting machine for aluminum profiles includes a base frame, a conveyor roller, a shot blasting chamber, and a shot cylinder. The conveyor roller is mounted on the base frame, and the shot blasting chamber is located in the middle of the base frame. The conveyor roller passes through the shot blasting chamber, and the shot cylinder is mounted above the shot blasting chamber. The shot blasting chamber has a polygonal cross-section. The interior of the polygonal shot blasting chamber forms multiple upper shot blasting ramps and multiple lower shot blasting ramps. At least one shot blaster is mounted on each upper shot blasting ramp and each lower shot blasting ramp. The shot blaster is inclined towards the aluminum profile on the conveyor roller. Each shot blaster is connected to the bottom of the shot cylinder through a corresponding upper shot blasting connector or lower shot blasting connector and a shot discharge pipe. A collecting hopper is provided at the bottom of the shot blasting chamber, and a discharge nozzle is provided at the bottom of the collecting hopper. A baffle is provided on one side below the discharge nozzle, and a separating fan is provided on the other side below the discharge nozzle. The side of the baffle near the separating fan is the shot outlet, and the other side of the baffle is the impurity outlet.
