[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The utility model provides a technical solution: an automatic feeding device for spring shot blasting, comprising a feeding hopper 1, both sides of the feeding hopper 1 are connected to pillars 2, the bottom ends of the pillars 2 are provided with connecting ears 6, and the connecting ears 6 are connected with fixing bolts through a threaded structure. The pillars 2 provide stable support, and the connecting ears 6 serve as connection points, which facilitate the feeding hopper 1 to be firmly fixed to the corresponding part of the shot blasting machine. The lower end of the feeding hopper 1 is detachably mounted with a strip bracket 4, the two ends of the strip bracket 4 are inclined structures, and the middle of the bottom of the strip bracket 4 is A motor 5 is fixedly installed by bolts, and a protective shell is installed on the outside of the motor 5. A vertical shaft 7 driven to rotate by the motor 5 is provided in the middle of the top of the strip bracket 4. The output shaft of the motor 5 is connected to the bottom end of the vertical shaft 7. A material balancing seat 8 is installed on the top of the vertical shaft 7, and a connecting sleeve 9 is provided on the lower end of the vertical shaft 7. A material balancing ring 10 is provided on the outside of the connecting sleeve 9. Several groups of guide plates 11 are arranged around the inner wall of the material balancing ring 10 and the outer wall of the connecting sleeve 9. The feeding hopper 1 of this structure can be driven by the motor 5 to drive the vertical shaft 7 to rotate when in use, thereby driving the material balancing seat 8 rotates, the material balancing seat 8 surrounds the dispersed steel shots in advance, and the vertical shaft 7 also drives the sleeve 9 and the material balancing ring 10 to rotate together. At this time, several groups of guide plates 11 arranged between the inner wall of the material balancing ring 10 and the outer wall of the sleeve 9 will guide the steel shots falling into the material balancing ring 10, so that they are evenly diffused outward according to different directions and paths. This ensures that the steel shots can be evenly distributed to different areas inside the shot blasting machine, effectively avoiding the situation where the density of local steel shots is too high or too low, thereby improving the consistency and uniformity of the shot blasting effect, improving the quality of the spring surface treatment, and reducing the need for manual intervention, reducing labor costs, and improving production efficiency. Each group of guide plates 11 is staggered up and down between the inner wall of the material balancing ring 10 and the outer wall of the sleeve 9, and the guide plates 11 are all inclined at an angle of 30° to the horizontal plane. The special arrangement of the guide plates 11 of this structure can effectively guide the steel shots to different directions, avoiding the problem of excessively high or too low density of local steel shots, thereby improving the consistency and uniformity of the shot blasting effect.The material balancing seat 8 is an arched structure as a whole, and the top surface of the material balancing seat 8 is evenly surrounded by several guide grooves with arc-shaped inner walls. The material balancing seat 8 of this structure can guide the steel shots to flow evenly to the lower end of the feeding hopper 1 through several guide grooves, and then guide them to different directions by the guide plate 11, so as to finally achieve uniform distribution of the steel shots inside the shot blasting machine. The inner wall of the top of the material balancing seat 8 is welded and fixed with a clamping sleeve 16 that matches the top structure of the vertical shaft 7, and a rubber ring is provided at the edge of the bottom end of the clamping sleeve 16. The material balancing seat 8 of this structure can be clamped on the top of the vertical shaft 7 through the clamping sleeve 16 and fastened with a rubber ring to facilitate disassembly and assembly, which is more convenient to use. The inner walls on both sides of the lower end of the inside of the feeding hopper 1 are symmetrically welded and fixed with clamping rings 14, and the bottoms of both ends of the bar bracket 4 are provided with clamping columns 15 that match the structure of the clamping ring 14. When the structure on the bar bracket 4 needs to be replaced or repaired, this structure can be easily removed by simply removing the clamping column 15 from the clamping ring 14. The strip bracket 4 is simple and quick to operate, thereby improving the flexibility and convenience of the equipment. The outer sleeve of the pillar 2 is provided with a connecting sleeve 3, and the front end of the connecting sleeve 3 is connected to a locking bolt through a threaded structure. A fixing ring 12 is welded and fixed on the corresponding side of the connecting sleeve 3, and the outer walls on both sides of the lower end of the feeding hopper 1 are provided with a rotating column 13 inserted into the inside of the fixing ring 12, and the top of the fixing ring 12 is connected to a fixing screw for locking the rotating column 13 through a threaded structure. This structure allows the feeding hopper 1 to adjust the height and angle position as needed to adapt to different shot blasting machine models and working environments. That is, when the height or angle of the feeding hopper 1 needs to be adjusted, it is only necessary to loosen the fixing screw, rotate the rotating column 13, and then reposition it and tighten the fixing screw. The connecting sleeve 3 can be adjusted in height on the pillar 2 and fixed with a locking bolt. This enhances the applicability of the equipment and enables the feeding hopper 1 to flexibly adapt to different shot blasting processing requirements.

[0019] Working principle: When using the spring shot blasting automatic feeding device, first fix the feeding hopper 1 on the shot blasting machine through the support 2 and the connecting ear 6. During this process, the feeding hopper 1 can be flexibly adjusted to the appropriate height and angle by adjusting the rotating column 13 and the fixing screws on the connecting sleeve 3. Then install the strip bracket 4. When installing the strip bracket 4, the clamping column 15 can be clamped into the inside of the clamping ring 14. When the motor 5 is started, the vertical shaft 7 starts to rotate, driving the material balancing seat 8, the connecting sleeve 9 and the material balancing ring 10 to rotate together. After the steel shot falls into the guide groove in the material balancing seat 8, it will be evenly dispersed to the surrounding area. Then it will be guided to different directions and paths through the guide plate 11 to achieve uniform distribution of the steel shot inside the shot blasting machine. At the same time, the clamping sleeve 16 is tightly combined with the vertical shaft 7 to ensure the stable operation of the system. The strip bracket 4 can also be quickly disassembled and assembled by detaching the clamping column 15 from the clamping ring 14, which is convenient for maintenance and replacement, thereby completing a series of tasks.
