Description

Technical Field

[0001] This utility model relates to a spin-drying device, and more particularly to a rotary centrifugal spin-drying device, belonging to the field of lens processing technology. Background Technology

[0002] In the prior art, such as the utility model with application number CN201721017729.5, an electroplating dehydration machine for automotive parts is disclosed. This device uses partitions II and I to achieve layered placement of parts, which can speed up the drying process and optimize the drying effect of the parts. In addition, a special foot connection device is provided to ensure that the device will not vibrate too much during operation and extend the service life of the device. Furthermore, the heating and blowing device can accelerate the drying of parts and improve the overall work efficiency.

[0003] The above-mentioned applications still have shortcomings:

[0004] This type of electroplating dehydration machine for automotive parts places the parts in layers on a partition, which is fixed by blocks and lugs. However, the lateral restraint provided by the blocks and lugs is insufficient, as it lacks vertical restraint on the partition. The outer blocks of the partition are prone to upward displacement along the slide groove, potentially causing vibration during operation. This vibration not only accelerates wear on the equipment components but also generates noise pollution.

[0005] To address this issue, a rotary centrifugal drying device was designed to optimize the aforementioned problems. Utility Model Content

[0006] The main purpose of this invention is to provide a rotary centrifugal drying device to solve the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A rotary centrifugal drying device includes an outer barrel and a baffle inside the outer barrel. A rotating shaft is rotatably mounted on the middle position of the baffle via a bearing, and a driving mechanism is provided between the rotating shaft and the outer barrel.

[0009] The outer tub is equipped with a limiting mechanism at the top. A limiting cylinder is fixed at the top of the rotating shaft. The top of the limiting cylinder is evenly provided with L-shaped grooves. A groove is provided at the top of the bottom of the L-shaped groove. Springs are evenly fixed on the inner bottom wall of the limiting cylinder. A pressure plate is fixed at the top of the springs and is slidably connected to the inside of the limiting cylinder. A spin-drying tub is provided inside the outer tub. A fixing post is fixed at the middle of the bottom of the spin-drying tub. A locking block matching the width of the L-shaped groove is evenly provided on the outside of the fixing post.

[0010] Preferably, the limiting mechanism includes an internally threaded tube and a screw. The internally threaded tube is evenly installed through the outer side of the outer barrel. The screw is threaded inside the internally threaded tube. A C-shaped plate is rotatably installed at one end of the screw. Rollers are rotatably installed inside the C-shaped plate. A slide rod is fixed on one side of the C-shaped plate and above the screw. The slide rod passes through and extends to the outer side of the outer barrel.

[0011] Preferably, the bottom of the spin dryer is provided with a protective cover, and the top of the protective cover is uniformly fixed with mounting plates, which are fixedly connected to the bottom of the spin dryer.

[0012] Preferably, the drive mechanism includes a mounting shell and a driven wheel. The mounting shell is located on one side of the outer barrel. A motor is installed inside the mounting shell. The output shaft of the motor is fixed with a drive wheel. The driven wheel is located at the bottom of the rotating shaft. A belt is provided between the driven wheel and the drive wheel.

[0013] Preferably, a sliding hole is provided at the connection between the outer barrel and the sliding rod, and a wear-resistant layer is provided inside the sliding hole, while an anti-slip layer is provided on the outside of the locking block.

[0014] Preferably, the protective cover is a conical cover, the minimum inner diameter of the protective cover is greater than the outer diameter of the limiting cylinder, and the mounting plate is installed at the bottom of the spin dryer by bolts.

[0015] Preferably, the end of the screw is fixed with a handle, and the outside of the handle is provided with an anti-slip layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes the combined use of an outer tub, baffle, rotating shaft, limiting cylinder, L-shaped groove, recess, spring, pressure plate, spin-drying tub, fixing column, and locking block. By manually placing the spin-drying tub downwards and rotating it, the locking block engages with the recess to fix and limit the spin-drying tub. This makes installation convenient, improves the stability of spin-drying operations, simplifies the installation process, increases operational efficiency, and facilitates the quick deployment and removal of the equipment for use and daily maintenance.

[0018] 2. This utility model utilizes the combined use of an internally threaded tube, a screw, a U-shaped plate, rollers, and a slide bar. By rotating the screw, the rollers are driven to fit against the outside of the spin-drying drum, ensuring that the rollers are stably fitted against the spin-drying drum. When the spin-drying drum rotates at high speed, it can effectively limit the shaking of its upper part, improve operational stability, and ensure smooth spin-drying operation.

[0019] 3. This utility model uses a protective cover and a mounting plate together. The protective cover is installed at the bottom of the spin dryer through the mounting plate, which can effectively protect the bottom of the spin dryer and the mounting part of the rotating shaft, block water erosion, improve the corrosion resistance of the area, and enhance the overall protective performance.

[0033] Example 1

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a rotary centrifugal drying device, including an outer barrel 1 and a baffle 2 inside the outer barrel 1. A rotating shaft 3 is rotatably mounted on the middle position of the baffle 2 via a bearing, and a driving mechanism 4 is provided between the rotating shaft 3 and the outer barrel 1.

[0035] The outer tub 1 is equipped with a limiting mechanism 5 at the upper end. The top of the rotating shaft 3 is fixed with a limiting cylinder 6. The top of the limiting cylinder 6 is evenly provided with L-shaped grooves 7. The bottom of the L-shaped groove 7 is provided with a groove 8 near the upper part. The inner bottom wall of the limiting cylinder 6 is evenly fixed with springs 9. The top of the springs 9 is fixed with a pressure plate 10, and the pressure plate 10 is slidably connected to the inside of the limiting cylinder 6. The outer tub 1 is equipped with a spin-drying tub 11. The middle position of the bottom of the spin-drying tub 11 is fixed with a fixing post 12. The outer side of the fixing post 12 is evenly provided with locking blocks 13 that match the width of the L-shaped groove 7.

[0036] The operator places the precision plastic parts of the lens into the spin-drying tub 11 and manually inserts it into the outer tub 1. The spin-drying tub 11, along with the fixing post 12 and the outer locking block 13, aligns with the top opening of the L-shaped groove 7. Then, the operator presses the spin-drying tub 11 downwards, causing the locking block 13 to slide down along the L-shaped groove 7. Simultaneously, the fixing post 12 presses down on the pressure plate 10, compressing the spring 9. Once the locking block 13 reaches the bend of the L-shaped groove 7, the operator rotates the spin-drying tub 11 horizontally. The spin-drying tub 11 rotates the locking block 13 to the bottom end of the L-shaped groove 7. The operator releases the pressure, and the spring 9 returns to its original position, pushing the pressure plate 10 and the fixing post 12 upwards. The locking block 13 then engages with the groove 8, thus limiting the spin-drying tub 11 and preventing it from shaking or vibrating.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the limiting mechanism 5 further includes an internally threaded tube 501 and a screw 502. The internally threaded tube 501 is uniformly installed through the outer side of the outer barrel 1. The screw 502 is threadedly installed inside the internally threaded tube 501. A C-shaped plate 503 is rotatably installed at one end of the screw 502. A roller 504 is rotatably installed inside the C-shaped plate 503. A slide rod 505 is fixed on one side of the C-shaped plate 503 and above the screw 502. The slide rod 505 passes through and extends to the outer side of the outer barrel 1.

[0040] After the spin-drying drum 11 is placed inside the outer drum 1, the screw 502 is rotated in sequence. Under the threaded engagement of the internal threaded tube 501, the screw 502 drives the shaped plate 503 and the roller 504 to move outward of the spin-drying drum 11 until the roller 504 is in contact with the outside of the spin-drying drum 11. Under the limiting of the shaped plate 503 by the slide rod 505, the angular displacement of the shaped plate 503 and the roller 504 is prevented when the spin-drying drum 11 is limited. When the spin-drying drum 11 rotates and spins, the roller 504 plays a limiting and stabilizing role on the upper end of the spin-drying drum 11.

[0041] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a protective cover 14 is further provided at the bottom of the spin dryer 11, and an mounting plate 15 is uniformly fixed on the top of the protective cover 14, and the mounting plate 15 is fixedly connected to the bottom of the spin dryer 11.

[0042] The protective cover 14 is installed at the bottom of the spin dryer 11 via the mounting plate 15. The protective cover 14 protects the connection between the fixed column (12) and the limiting cylinder (6) between the bottom of the spin dryer 11 and the rotating shaft 3, reducing the erosion of this part by water and improving the protective effect.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, the drive mechanism 4 further includes a mounting shell 401 and a driven wheel 404. The mounting shell 401 is located on one side of the outer barrel 1. A motor 402 is installed inside the mounting shell 401. The output shaft of the motor 402 is fixed with a drive wheel 403. The driven wheel 404 is located at the bottom end of the rotating shaft 3. A belt 405 is provided between the driven wheel 404 and the drive wheel 403.

[0044] The starter motor 402 drives the drive wheel 403 to rotate, which in turn drives the driven wheel 404 to rotate via the belt 405. The driven wheel 404 then drives the rotating shaft 3 and the spin dryer 11 mounted on the top of the rotating shaft 3 to rotate, thus drying the lens components inside the spin dryer 11.

[0045] like Figure 4As shown, in a preferred embodiment, based on the above method, a sliding hole is further provided at the connection between the outer barrel 1 and the slide rod 505, and a wear-resistant layer is provided inside the sliding hole, and an anti-slip layer is provided on the outside of the locking block 13.

[0046] The sliding hole provides a stable sliding guide for the slide rod 505, and the wear-resistant layer can reduce the frictional wear between the slide rod 505 and the outer barrel 1, extend the service life of the components, and ensure the smoothness of the adjustment of the limit mechanism 5; the anti-slip layer on the outside of the locking block 13 increases the friction between it and the groove 8, and improves the stability after locking.

[0047] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the protective cover 14 is a conical cover, the minimum inner diameter of the protective cover 14 is greater than the outer diameter of the limiting cylinder 6, and the mounting plate 15 is installed at the bottom of the spin dryer 11 by bolts.

[0048] The conical structure guides the ejected water outwards to avoid accumulation; the bolted connection facilitates the disassembly and maintenance of the protective cover 14, improving equipment maintenance efficiency.

[0049] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the end of the screw 502 is further fixed with a handle, and an anti-slip layer is provided on the outer side of the handle.

[0050] The handle increases the point of force application for the hand, making the rotation adjustment of the screw 502 easier; the anti-slip layer increases friction to prevent hand slippage during operation, improving the convenience and stability of the limit mechanism 5 adjustment.

[0051] Example 3

[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0053] The protective cover 14 is installed at the bottom of the spin dryer 11 via the mounting plate 15, and the protective cover 14 covers the outside of the fixing column 12;

[0054] The spin-drying tub 11 is placed inside the outer tub 1 so that the locking block 13 on the outside of the fixing post 12 at the bottom of the spin-drying tub 11 is aligned with the opening at the top of the L-shaped groove 7. The spin-drying tub 11 is pressed down so that the fixing post 12 and the locking block 13 slide down along the L-shaped groove 7. At the same time, the bottom of the fixing post 12 presses down on the pressure plate 10, compressing the spring 9 at the bottom of the pressure plate 10. When the locking block 13 slides to the turning point of the L-shaped groove 7, the spin-drying tub 11 is rotated horizontally, causing the fixing post 12 and the locking block 13 to rotate to the bottom end of the L-shaped groove 7. After releasing, the spring 9 returns to its original position, pushing the pressure plate 10 and the fixing post 12 to move upward. At the same time, the locking block 13 moves upward and locks into the groove 8, thus fixing and limiting the spin-drying tub 11.

[0055] The protective cover 14 at the bottom of the spin dryer 11 covers the outside of the fixing post 12 and the limiting cylinder 6 as the locking block 13 engages with the groove 8, thus protecting the outside of the fixing post 12 and the limiting cylinder 6.

[0056] Then, the screw 502 is rotated in sequence, which is threaded into the internal threaded tube 501, driving the shaped plate 503 and the roller 504 to move outward of the spin-drying drum 11. The roller 504 fits against the outside of the spin-drying drum 11. The slide rod 505 restricts the rotation of the shaped plate 503, ensuring that when the spin-drying drum 11 rotates, the roller 504 forms a stable limit on its upper part.

[0057] The starter motor 402 drives the drive wheel 403 to rotate, which in turn drives the driven wheel 404 via the belt 405, thereby causing the rotating shaft 3 and the top spin dryer 11 to rotate, completing the spin dryer operation of the lens components inside the spin dryer 11.

[0058] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
