Description

Technical Field

[0001] This utility model relates to the field of metal shaft core surface processing technology, and specifically to a metal shaft core surface anti-corrosion treatment device. Background Technology

[0002] Metal shafts are widely used in many industrial applications, but their surfaces are susceptible to corrosion, especially in humid, acidic, or alkaline environments. Corrosion leads to a decline in the physical properties of the metal surface, such as reduced strength, shortened fatigue life, and may even cause equipment failure. Therefore, effective anti-corrosion treatment of metal shafts is an important means to improve their service life and reliability.

[0003] According to patent document CN205309236U, a casting sand core impregnation device is disclosed, including a base, a support column, and an impregnation tank. The base is rectangular, and the impregnation tank is fixed to the upper end of the base. The support column is located on the upper end of the base on one side of the impregnation tank. The impregnation tank includes an outer casing and an inner cylinder. The inner cylinder is embedded in the outer casing, and a drive shaft is provided at the bottom of the inner cylinder. Multiple blades integrally formed with the inner cylinder are provided on the inner bottom surface of the inner cylinder. A motor is provided inside the lower end of the support column, and the output end of the motor is connected to the drive shaft via a belt. A cantilever is fixed to the top of the support column, and a vertically installed cylinder is fixed to the free end of the cantilever. A telescopic rod is fixed to the output end of the cylinder, and an impregnation frame is fixed to the bottom end of the telescopic rod.

[0004] Currently, traditional metal shaft core surface anti-corrosion treatment devices require the application of coatings to the shaft core surface for anti-corrosion treatment. The common processing mode is manual operation. Because the coating is static, it will settle after a period of use, resulting in uneven coating quality, unstable coating thickness, and fluctuations in coating concentration. This can lead to waste products due to coating accumulation, affecting product quality and yield, resulting in low production efficiency and making it unsuitable for large-scale production.

In the current traditional metal shaft core surface anti-corrosion treatment device, it is necessary to first apply a coating to the surface of the shaft core for anti-corrosion treatment. The common processing mode is mainly manual operation. Because the coating is static, it will settle after a period of use, resulting in uneven coating quality, unstable coating thickness, easy fluctuation of coating concentration, and product waste due to coating accumulation. This affects the quality and yield of the product, leading to low production efficiency and unsuitability for large-scale production.

[0007] The spraying mechanism includes a motor, the upper end of which is detachably connected to the lower end of a fixed plate. A gear set is mounted on the motor's output shaft. A hollow tube is inserted into one side of the gear set. A limit ring is fixed to the upper end of the hollow tube. A rotating seat is sleeved on the outer wall of the limit ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The spraying mechanism allows the equipment to uniformly spray anti-corrosion coating onto the metal shaft core. The motor starts, driving the gear set to rotate, which in turn rotates the hollow tube, which in turn rotates the rotating frame, which in turn rotates the placement seat, which in turn rotates the carrying plate, which in turn rotates the metal shaft core. Simultaneously, the pump draws the anti-corrosion coating into the inlet pipe and discharges it into the first diversion pipe through the outlet pipe. The coating is then sprayed onto the top of the metal shaft core through nozzle one, and leaks through the drain holes to the bottom of the inner wall of the rotating frame. Finally, nozzle two at the upper end of the second diversion pipe sprays the bottom of the metal shaft core, resulting in more uniform spraying and improving the practicality of the device.

[0016] 2. The drying mechanism allows the equipment to quickly dry the metal shaft core, preventing paint dripping and improving the efficiency of the device. The liquid pump draws hot water from the hot water tank through one end of the circulation pipe and then re-enters the tank. Simultaneously, the fan is activated to circulate air within the tank, drying the metal shaft core. The fan generates airflow to accelerate the drying process. The hot water in the tank can be recycled, saving energy and protecting the environment. The support base facilitates the installation and fixing of the circulation pipe and allows for long-term use.
