Detailed Implementation

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0027] The principle of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] This utility model proposes a metal product spin dryer, including a spin dryer 1 and a top cover 2 covering the opening at the top of the spin dryer 1. The spin dryer 1 contains a rotating tray frame 4 driven by a spin dryer motor 3. The top cover 2 is equipped with a fan 5 and a heating element 6. The spin dryer 1 has an air outlet 11, and the top cover 2 has an air inlet 21. The air outlet 11 and the air inlet 21 are connected by a return air pipe 7. The metal product spin dryer recovers hot air in the exhaust and drainage section 13 and recycles it by sending it back to the top cover 2 through the return air pipe 7, thus reducing the energy consumption of hot air drying.

[0029] In this embodiment, the rotating tray frame 4 is provided with a cross groove 41, and multiple rectangular trays 42 are stacked alternately in the cross groove 41. The rectangular trays 42 are divided into multiple small compartments for storing finished or semi-finished hardware parts, and each small compartment has a through hole at the bottom for ventilation and dripping. The alternating stacking of the rectangular trays 42 can improve ventilation and drying efficiency. To further improve ventilation and spin-drying effect, the rotating tray frame 4 is provided with several horizontal through holes 43 for ventilation in both the front-back and left-right directions. The water droplets that are spun out can pass through the horizontal through holes 43 and slide down the inner wall of the spin-drying drum 1, avoiding accumulation on the rotating tray frame 4.

[0030] In this embodiment, the spin-drying drum 1 is composed of a base 12, an exhaust and drainage section 13, and a spin-drying section 14 arranged sequentially from bottom to top. The spin-drying motor 3 is fixed in the inner cavity of the base 12. A water-receiving tray 8 is provided at the bottom of the inner cavity of the exhaust and drainage section 13, which separates the inner cavity of the base 12 from the inner cavity of the exhaust and drainage section 13. A rotating tray frame 4 is disposed in the inner cavity of the spin-drying section 14, and the rotating shaft of the spin-drying motor 3 passes through the water-receiving tray 8 and is connected to the bottom of the rotating tray frame 4. The water-receiving tray 8 is used to collect water droplets dripping from the workpiece and to isolate the inner cavity of the base 12 to prevent water from entering the spin-drying motor 3.

[0031] In this embodiment, the water receiving tray 8 arches upwards in the middle to form a conical surface. Several circumferentially arranged exhaust and drainage holes 131 are provided at the connection point between the edge of the water receiving tray 8 and the wall of the exhaust and drainage section 13. An annular water trough 9 is provided around the exhaust and drainage section 13, and the exhaust and drainage holes 131 are connected to the annular water trough 9. An air outlet 11 is located on the periphery of the annular water trough 9 and is connected to the air inlet 21 via a return air pipe 7. A drain outlet 91 is also provided at the bottom of the annular water trough 9, and the drain outlet is connected to a drain pipe via a flexible hose. The conical water receiving tray 8 allows water droplets spilled from the hardware to be quickly collected and drained into the external annular water trough 9, preventing the water droplets from evaporating and absorbing heat.

[0032] In this embodiment, a support 141 is provided at the bottom of the inner cavity of the spin-drying section 14, and the bottom of the rotating tray frame 4 is rotatably mounted on the support 141 via a support bearing 142. The support bearing 142 has a high load-bearing capacity and can maintain good rotational ability under the pressure of the rotating tray frame 4, the rectangular tray 42, and the hardware. In addition, an annular track 143 is provided on the inner wall of the spin-drying section 14, and several side pulleys 44 are evenly arranged on the periphery of the rotating tray frame 4, rolling along the annular track 143. The side pulleys 44 help the rotating tray frame 4 maintain stability under the centrifugal force generated by rotation, avoiding collision with the spin-drying drum 1 or damage to the support bearing 142, and also avoiding noise caused by collision.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
