[0015] The shading ring to be dried is placed outside the installation shaft, and the shading ring is supported by a support ring so that the shading ring is suspended in the air;

[0016] The third rotating shaft is driven to rotate by a motor, thereby causing a plurality of first bevel gears to rotate synchronously, and the second bevel gear is driven to rotate by the first bevel gear, thereby causing a plurality of worms to rotate synchronously;

[0018] When the dried light shielding ring needs to be taken out, the position of the cover plate is limited by the design of the vertical limit mechanism to prevent the cover plate from moving in the vertical direction;

[0019] When the limit on the vertical direction of the cover is released, the cover is manually driven to move upward, so that the second rotating shaft moves upward, and then the second plug block is disengaged from the corresponding second slot, so that the first rotating shaft and the second rotating shaft no longer clamp the corresponding installation shaft, and the limit on the position of the installation shaft is released;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The shading ring to be dried is sleeved on the outside of the mounting shaft, and the shading ring is supported by a supporting ring so that the shading ring is suspended in the air. The third rotating shaft is driven by a motor to rotate, thereby causing a plurality of first bevel gears to rotate synchronously. The second bevel gear is driven to rotate by the first bevel gear, thereby causing a plurality of worms to rotate synchronously. The worm drives the worm wheel and the first rotating shaft to rotate, thereby causing the mounting shaft located above the first rotating shaft to rotate, thereby causing the shading ring to rotate. While the shading ring is suspended in the air, the shading ring can rotate, so that each part of the shading ring is dried more evenly, thereby improving the drying efficiency and reducing the drying time.

[0023] (2) When the dried light shielding ring needs to be taken out, the position of the cover plate is limited by the design of the vertical limit mechanism to prevent the cover plate from moving in the vertical direction. When the limit on the vertical direction of the cover plate is released, the cover plate is manually driven to move up, so that the second rotating shaft moves up, and then the second plug is disengaged from the corresponding second slot, so that the first rotating shaft and the second rotating shaft no longer clamp the corresponding installation shaft, and the limit on the position of the installation shaft is released. By manually driving the installation shaft to move up, the first plug is disengaged from the corresponding second slot, and the installation shaft can be removed. Then, the light shielding ring sleeved on the outside of the installation shaft is manually removed, which is convenient for removing the dried light shielding ring;

[0024] (3) The handle is manually driven to move, so that the movable plate moves away from the fixed block, the tension spring is in a stretched state, the limit bar is disengaged from the limit groove, and the fixed relationship between the movable plate and the fixed block is released, so that the cover plate and the movable plate can move in the vertical direction relative to the drying processing box, and the sliding plate moves with the movable plate. The design of the limit plate prevents the sliding plate from being separated from the second fixed plate;

[0025] (4) During the drying process, the air pump is started, and the gas in the drying processing box enters the drying box through the first exhaust pipe and the second connecting pipe. The desiccant in the drying box adsorbs water vapor in the gas to reduce the moisture content in the air. The gas with reduced water content enters the drying processing box again through the first connecting pipe and the first air inlet pipe, which can reduce the moisture content in the gas in the drying processing box and further improve the drying efficiency.

A method for producing a burr-free light shielding ring, comprising the burr-free light shielding ring production device according to claim 4, Features: The following steps are involved: The shading ring to be dried is sleeved on the outside of the installation shaft (11), and the shading ring is supported by a support ring (12) so that the shading ring is suspended in the air; The third rotating shaft (15) is driven to rotate by a motor (17), thereby causing the plurality of first bevel gears (18) to rotate synchronously, and the second bevel gear (19) is driven to rotate by the first bevel gear (18), thereby causing the plurality of worm gears (3) to rotate synchronously; The worm gear (4) and the first rotating shaft (5) are driven to rotate by the worm (3), thereby causing the mounting shaft (11) located above the first rotating shaft (5) to rotate, thereby causing the light shielding ring to rotate, so that all parts of the light shielding ring are dried evenly; When it is necessary to take out the dried light shielding ring, the position of the cover plate (2) is limited by the design of the vertical limiting mechanism to prevent the cover plate (2) from moving in the vertical direction; When the limit on the cover plate (2) in the vertical direction is released, the cover plate (2) is manually driven to move upward, so that the second rotating shaft (7) moves upward, and then the second plug block (14) is disengaged from the corresponding second slot (13), so that the first rotating shaft (5) and the second rotating shaft (7) no longer clamp the corresponding installation shaft (11), and the limit on the position of the installation shaft (11) is released; The installation shaft (11) can be removed by manually driving the installation shaft (11) upward so that the first plug block (10) is disengaged from the corresponding second slot (13), and then the light shielding ring sleeved on the outside of the installation shaft (11) can be manually removed.
