TECHNICAL FIELD
[0001] The present application relates to the technical field of sizing equipment, in particular to a sizing equipment for electroplating hangers. BACKGROUND
[0002] The hanger mainly plays the role of conducting electricity, supporting and fixing parts in electroplating production. The hanger is connected with the electrode, so that the current is uniformly transmitted to the parts for electroplating. In some cases, due to the solution performance limiting the uniform distribution of the plating layer, the hanger can also be relied on to make up for it. Therefore, the electroplating hanger needs to be insulated, that is, except for the part that needs to be in contact with the part and requires conductivity, other parts are wrapped or coated with non-metallic materials to make it a non-conductor. In this way, the current of the electroplating process can be concentrated on the parts to speed up the deposition rate, while saving metal materials and power consumption. When the hanger is stripped and pickled, the corrosion of the hanger can also be reduced, prolonging the service life of the hanger.
[0003] The electroplating hanger needs to be sized to become a non-conductor, which is a necessary condition for use. As disclosed in CN109926280A, a sizing equipment for electroplating hangers, the traditional technology places the hanger in a hanger powder container after heating it in an oven. The high-temperature surface of the hanger contacts the hanger powder, which melts the solid particles into a liquid colloid and adheres to the surface of the hanger. Through technical design, the hanger is shaken left and right before and after the sizing process to solve the problems of uneven, insufficient, and partial sizing. Only shaking in the horizontal plane, the molten liquid colloid is prone to deposit in the lower part of the hanger under the action of gravity before solidification, causing uneven coverage of the liquid colloid, more in the lower part and less in the upper part, poor sizing quality, and further reducing the electroplating quality of the electroplating product.

[0037] 4. As the rotor rotates eccentrically, the volume of each active space in this equipment changes periodically. Generally speaking, the volume of the active space gradually increases as it moves closer to the air inlet and gradually decreases as it moves closer to the air outlet. This draws outside air into the active space, which then forces the air into the air outlet, and then into the blowing pipe. Finally, the air is ejected through multiple blowing heads, which inhibits the sagging of liquid colloids and accelerates their solidification. Three air inlets and outlets can be achieved in one rotor rotation, resulting in high air delivery efficiency, which is beneficial for drying. Attached Figure Description

[0076] The air cylinder 47 is fixedly connected to one side of the frame box body 1.
[0077] The rotor 471 has a shape similar to a Lohr triangle and is in tooth connection with the central shaft 44 and in airtight cooperation with the inner wall of the air cylinder 47. The rotor 471 has three convex planes and three vertices, and a regular triangle and a Lohr triangle can be formed by the three vertices. The regular triangle has three planes a, and the Lohr triangle has three convex planes b.

[0079] The air blowing pipe 41 is connected with the air cylinder 47 through the air outlet pipe 473. The air cylinder 47 is provided with an air inlet hole 472 connected with the outside, and a one-way valve is arranged in the air inlet hole 472 and the air outlet pipe 473.

The rotor 471 forms three active spaces in the air cylinder 47. Referring to Figure 6 With the eccentric rotation of the rotor 471, the volume of each active space periodically changes. In general, the volume of the active space gradually increases in the process of moving close to the air inlet hole 472 and gradually decreases in the process of moving close to the air outlet pipe 473. Then, the external air is sucked into the active space. The active space pressurizes the air into the air outlet pipe 473 and then into the air blowing pipe 41. Finally, the air is sprayed out through the plurality of air blowing heads 42, thereby inhibiting the liquid colloid from sagging and accelerating the solidification speed.
