Description

Technical Field

[0001] This utility model relates to the field of blade polishing technology, and in particular to a blade polishing device for a high-speed blower. Background Technology

[0002] Polishing the blades of a hair dryer is a highly technical task requiring precision and skill. Its main purpose is to improve the smoothness of the blade surface, reduce airflow resistance, thereby increasing airflow efficiency. It also helps extend motor life and reduce noise. In high-speed hair dryers, because the blade structure is often a one-piece design, the angles between the blades and curved areas can easily create polishing dead zones, making it difficult to achieve a comprehensive and uniform finish using traditional manual polishing methods.

[0003] To address this issue, sandblasting is currently the most common surface polishing process. This method utilizes high-speed airflow to propel abrasive particles against the surface of the fan blades, effectively removing burrs, oxide layers, and minor imperfections to achieve a good smoothness. However, in actual production, due to the complex structure of the fan blades, frequent manual adjustments to their angle and position at the sandblasting nozzle are necessary to ensure all areas are adequately treated. This not only reduces processing efficiency but also increases the workload and attentional burden on operators, impacting the overall production rhythm.

[0004] Therefore, there is an urgent need for a high-speed blower blade polishing device that can achieve uniform polishing at different angles without disassembling the blades, thereby improving product quality and production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a blade polishing device for a high-speed hair dryer.

[0006] The technical solution is as follows: A high-speed blower blade polishing device includes a bracket, a housing, a sandblasting machine, a mounting plate, a drive shaft, a first gear, a chain, a motor, a mounting frame, a placement rod, a second gear, and a rack. The housing is mounted on the bracket, and the sandblasting machine is mounted on the housing. The outlet of the sandblasting machine has nozzles arranged in a front-to-back pattern. A set of mounting plates is provided on both the left and right sides of the housing. Two mounting plates in the same set are arranged vertically and alternately. A drive shaft rotates between the two mounting plates in the same set. A first gear is provided at both ends of the drive shaft. A chain is provided between two opposing first gears. A motor is mounted on one of the mounting plates, and the output end of the motor is connected to the shaft end of the adjacent drive shaft. Mounting frames are arranged alternately between the chains on both sides. A placement rod for placing the blower blades is rotated on each mounting frame. A second gear is provided at the end of the placement rod. A rack that meshes with the second gear is provided on the inner wall of the housing.

[0007] Preferably, the system also includes a collection frame, which is located at the bottom of the outer casing and connected to a pipe for recycling sand.

[0008] Preferably, it also includes a convex plate and an elastic element, with the convex plate symmetrically sliding through the rod and the elastic element disposed between the two convex plates.

[0009] Preferably, both sides of the convex plate have curved surfaces.

[0010] Preferably, the collection frame also includes inclined plates, with inclined plates tilted towards the center on both sides.

[0011] Preferably, it also includes a dust collector, which is mounted on the outer casing and whose duct passes through the wall of the outer casing.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model achieves automatic conveying and precise positioning of the blower blades through a linkage structure composed of a motor-driven transmission shaft, chain, and mounting bracket; combined with the continuous operation mode of the sandblasting machine, it significantly reduces manual intervention, improves overall processing efficiency, and when the blower blades enter the sandblasting area, the second gear meshes with the rack and pinion, driving the placement rod to rotate, so that the blower blades rotate synchronously during the sandblasting process, thereby achieving comprehensive and uniform grinding of all angles of the blades, effectively improving surface finish and aerodynamic performance.

[0013] 2. This utility model, through the protruding plate and elastic element structure set on the placement rod, can achieve automatic fixation during the insertion of the blower blade.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: A blade polishing device for a high-speed hair dryer, such as... Figures 1-4 As shown, the device includes a bracket 1, a housing 2, a sandblasting machine 3, a mounting plate 5, a drive shaft 6, a first gear 7, a chain 8, a motor 9, a mounting bracket 10, a placement rod 11, a second gear 12, and a rack 13. The bracket 1 serves as the basic support structure for the entire device, bearing and fixing other components to ensure the stability and safety of the machine during operation. The housing 2 is fixedly mounted on top of the bracket 1. The housing 2 has a hollow structure, which not only protects the internal components but also effectively prevents sand from splashing during sandblasting, improving the safety and cleanliness of the operating environment. The sandblasting machine 3 is mounted on top of the housing 2. The outlet of the sandblasting machine 3 has front and rear arranged nozzles for spraying sand onto the surface of the blower blades 14, achieving efficient deburring, oxide layer removal, and polishing. Simultaneously, the front... The rear-arranged nozzles effectively enhance the sandblasting coverage and improve grinding efficiency and uniformity. A set of mounting plates 5 is fixedly installed on both the left and right sides of the outer casing 2. The two mounting plates 5 in the same set are arranged vertically and horizontally. A drive shaft 6 rotates between the two mounting plates 5 in the same set. First gears 7 are installed at both ends of the drive shaft 6. A chain 8 is installed between the two opposing first gears 7. A motor 9 is installed on one of the mounting plates 5, and the output end of the motor 9 is connected to the shaft end of the adjacent drive shaft 6. Mounting brackets 10 are arranged at intervals between the chains 8 on both sides. Each mounting bracket 10 has a rotating mounting rod 11 for placing the blower blades 14. A second gear 12 is installed at the end of the mounting rod 11. A rack 13 meshing with the second gear 12 is installed on the inner wall of the outer casing 2.

[0021] Therefore, the chain drive assembly consisting of the transmission shaft 6, the first gear 7, and the chain 8, driven by the motor 9, drives the mounting frame 10 and the placement rod 11 to rotate cyclically, realizing the automatic feeding, processing, and discharging of the blower blades 14, reducing manual intervention and improving production efficiency. During this process, the meshing structure of the second gear 12 and the rack 13 also allows the blower blades 14 to rotate automatically as they pass through the sandblasting area, thereby achieving comprehensive and uniform sandblasting treatment at all angles of the blades and improving the surface polishing quality of the blower blades 14.

[0022] like Figure 2 As shown, it also includes a collection frame 4. The bottom of the outer shell 2 is provided with a collection frame 4, and the collection frame 4 is connected to a pipe for recycling sand. It can effectively recycle the used sand, realize the recycling of sand, reduce production costs, improve the cleanliness of the equipment, and reduce the amount of subsequent cleaning work.

[0023] like Figure 4 As shown, it also includes a convex plate 15 and an elastic element 16. The convex plate 15 is symmetrically slidably inserted on the placement rod 11. Both sides of the convex plate 15 have arc-shaped surfaces 17. An elastic element 16 is provided between the two convex plates 15. In this embodiment, the elastic element 16 is a spring. When the blower blade 14 is inserted, the inner wall of the blower blade 14 pushes the convex plate 15 to slide along the rod, thereby compressing the elastic element 16. When the blower blade is in place, the elastic element 16 resets so that the convex plate 15 is tightly attached to the inner wall of the blower blade 14, forming an adaptive abutment fixation.

[0024] like Figure 2 As shown, it also includes inclined plates 18. Inclined plates 18 are provided on both sides of the collection frame 4, which are inclined towards the center to guide the falling sand to the center of the collection frame 4 for easy discharge through the pipe.

[0025] like Figure 2 As shown, it also includes a dust collector 19. The dust collector 19 is installed on the outer casing 2. The air duct of the dust collector 19 passes through the wall of the outer casing 2. Before the blower blades 14 enter the sandblasting area, the dust collector 19 performs pre-dust removal treatment to remove surface dust, debris and other impurities.

[0026] During use, the device is first placed stably, then the feeding equipment is connected to one side of the device, and the blower blades 14 to be processed are prepared. After starting the motor 9, the motor 9 drives the transmission shaft 6 connected to it to rotate, thereby driving the first gear 7 on the transmission shaft 6 to rotate, further driving the chains 8 on both sides to circulate. The mounting frame 10 and the placement rods 11 move synchronously to achieve continuous turnover operation. At the same time, the feeding equipment is started, and the blower blades 14 to be processed are installed on each placement rod 11 in sequence. When the blower blades 14 are inserted into the placement rods 11, they first contact the arc-shaped surface 17 of the convex plate 15, thereby pushing the two convex plates 15 to slide along the placement rods 11 and compressing the elastic element 16; when the blower blades 14 are installed in place, the elastic element 16 returns to its original shape, causing the convex plates 15 to fit tightly against the inner wall of the blower blades 14, thereby achieving a stable abutment and fixation, ensuring that the blower blades 14 will not loosen during subsequent processing. In this way, the clamping operation of multiple blower blades 14 can be completed efficiently. Subsequently, ensure that the sandblasting machine 3 is properly connected to the abrasive supply system. When the blower blades 14 are conveyed to the sandblasting area by the chain 8, the second gear 12 meshes with the rack 13, driving the placement rod 11 to rotate around the mounting frame 10, thereby causing the blower blades 14 to rotate synchronously. At this time, the sandblasting machine 3 performs uniform sandblasting on the continuously rotating blower blades 14 below, achieving all-round grinding and polishing of its surface. This structural design not only improves processing efficiency but also ensures the continuity and integrity of the process. A collection frame 4 is provided at the bottom of the device for collecting fallen abrasive; the inclined plates 18 on both sides can guide the abrasive through the pipes for easy recycling and reuse. In addition, the dust collector 19 can be started to remove dust from the blower blades 14 before they enter the grinding and polishing process, thereby improving the quality of subsequent processing and reducing impurity interference.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
