Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a high-efficiency and energy-saving precision electroplating dryer. Background Technology

[0002] An electroplating dryer is a device used in the electroplating process to improve the drying speed and quality of products. Its main function is to rapidly evaporate the moisture on the surface of electroplated parts after electroplating using high-speed hot air, infrared rays, or radiation, thereby achieving the purpose of drying.

[0003] To overcome the aforementioned shortcomings, a Chinese patent (publication number: CN221781073U) discloses an electroplating dryer, belonging to the field of electroplating processing technology. This solves the problem that such equipment requires a large floor space for manufacturers, resulting in low land utilization. The dryer includes an open-top tank, several connecting plates fixedly connected to the tank, several support plates fixedly connected between adjacent connecting plates, and a movable agitator above the tank. The cleaned electroplated workpieces are placed in the tank above the perforated support plates for drying. A fan is activated, allowing outside air to flow rapidly over the workpiece surface, carrying away moisture. A vibrating motor inside the tank operates, causing changes in the gaps between the workpieces through vibration, improving airflow. Simultaneously, the motor drives a rotating shaft, connecting rods, and blades to agitate the workpieces. The staggered blades prevent the workpieces from detaching from the tank, promoting moisture evaporation. This dryer offers advantages in drying efficiency and space saving, allowing for stacked storage instead of flat laying, effectively utilizing factory space.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: electroplated parts usually have residual electroplating solution on their outer side after electroplating, so they need to be dried as a whole. Existing electroplated parts drying devices are not convenient for drying the whole part and are prone to leaving drying dead corners. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency and energy-saving precision electroplating dryer to solve the problem in the background art that the electroplating drying device is not convenient for drying the whole part and is prone to leaving drying dead corners.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving precision electroplating dryer, including a sealed box, wherein a hot air blower is fixedly connected to the top of the sealed box, and the output end of the hot air blower extends into the interior of the sealed box;

[0007] The sealed box is equipped with a hoisting structure for hoisting electroplated parts. The hoisting structure includes a fixed sleeve that is fixedly connected to the top of the inner side of the sealed box. A rotating sleeve is rotatably connected inside the fixed sleeve. A ring of equally spaced connecting rods is fixedly connected to the outer side of the lower end of the rotating sleeve. A planetary gear is rotatably connected to the end of each connecting rod away from the rotating sleeve. A hook is fixedly connected to the bottom of the planetary gear.

[0008] Preferably, the top and bottom of the rear side of the sealed box are respectively provided with an air inlet pipe and an air outlet pipe, and the air inlet pipe and the air outlet pipe are distributed tangentially to the sealed box. The tangential directions of the air inlet pipe and the air outlet pipe are opposite, and the air inlet pipe is connected to the output end of the hot air blower.

[0009] Preferably, the sealing box has a sealing door hinged to the front side, and a guide strip with a spiral structure is fixedly connected inside the sealing box, and the guide strip extends to the inside of the sealing door.

[0010] Preferably, the outer side of the rotating sleeve is fixedly connected with pneumatic baffles that are distributed in an annular pattern at equal intervals, and the end of the pneumatic baffle away from the rotating sleeve is aligned with the connection between the air inlet pipe and the sealing box.

[0011] Preferably, the fixed sleeve has two sets of bearing steel balls arranged in an annular equidistant structure rotatably connected inside, and the two sets of bearing steel balls are in contact with the upper and lower sides of the upper end of the rotating sleeve, respectively, and the rotating sleeve can rotate relative to the fixed sleeve.

[0012] Preferably, both the fixed sleeve and the rotating sleeve have mutually aligned openings inside, and a fixed rod is fixedly connected inside the opening, and the fixed rod is fixedly connected to the top of the sealing box.

[0013] Preferably, a fixed gear is fixedly connected to the lower end of the fixed rod, and the outer side of the fixed gear meshes with the planetary gear.

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

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a high-efficiency and energy-saving precision electroplating dryer, comprising a sealed box 1, a hot air blower 2 fixedly connected to the top of the sealed box 1, and the output end of the hot air blower 2 extending into the interior of the sealed box 1; a hoisting structure for hoisting electroplated parts is installed inside the sealed box 1, and the hoisting structure includes a fixed sleeve 7 fixedly connected to the top of the inner side of the sealed box 1, a rotating sleeve 8 rotatably connected inside the fixed sleeve 7, and a ring of equally spaced connecting rods 10 fixedly connected to the outer side of the lower end of the rotating sleeve 8, and a planetary gear 11 rotatably connected to the end of each connecting rod 10 away from the rotating sleeve 8, and a hook 12 fixedly connected to the bottom of the planetary gear 11; an air inlet pipe 3 and an air outlet pipe 4 are respectively provided at the top and bottom of the rear side of the sealed box 1, and the air inlet pipe 3 and the air outlet pipe 4 are tangentially distributed with respect to the sealed box 1, the tangential directions of the air inlet pipe 3 and the air outlet pipe 4 are opposite, and the air inlet pipe 3 is connected to the output end of the hot air blower 2.

[0026] When using the dryer, first open the sealing door 5 to open the front of the sealing box 1, and then hang the electroplated parts on the hook 12. Next, close the sealing door 5 to seal the inside of the sealing box 1, and then start the hot air blower 2 to fill the sealing box 1 with hot air. The hot air blower 2 sends the hot air into the sealing box 1 through the air inlet pipe 3. At this time, the hot air circulates inside the sealing box 1, thereby drying the electroplated parts. Since the air outlet of the air inlet pipe 3 is aligned with the pneumatic baffle 9, the hot air entering the sealing box 1 will blow the pneumatic baffle 9 to move. With the pneumatic baffles 9 distributed equidistantly in a ring on the outside of the rotating sleeve 8, the pneumatic baffles 9 will drive the rotating sleeve 8 to rotate within the fixed sleeve 7.

[0027] The connecting rods 10 on the outer side of the lower end of the rotating sleeve 8 are arranged in a ring-shaped equidistant structure. Therefore, during the rotation of the rotating sleeve 8, the connecting rods 10 will drive the connecting rods 10 to rotate around its center. The rotation of the connecting rods 10 will in turn drive the planetary gear 11 and the hook 12 fixedly connected to its bottom to rotate. At this time, the electroplated parts suspended on the hook 12 will rotate inside the sealed box 1, thereby making their contact with the hot air more uniform and improving the drying efficiency.

[0028] Example 2: Based on Example 1, the following structure is also disclosed: A sealing door 5 is hinged to the front side of the sealing box 1, and a guide strip 6 with a spiral structure is fixedly connected inside the sealing box 1, and the guide strip 6 extends to the inside of the sealing door 5; A pneumatic baffle 9 with annular equidistant distribution is fixedly connected to the outside of the rotating sleeve 8, and the end of the pneumatic baffle 9 away from the rotating sleeve 8 is aligned with the connection between the air inlet pipe 3 and the sealing box 1; Two sets of bearing steel balls 15 with annular equidistant distribution are rotatably connected inside the fixed sleeve 7, and the two sets of bearing steel balls 15 are respectively in contact with the upper and lower sides of the upper end of the rotating sleeve 8, and the rotating sleeve 8 can rotate relative to the fixed sleeve 7; Both the fixed sleeve 7 and the rotating sleeve 8 are provided with mutually aligned openings, and a fixed rod 14 is fixedly connected inside the opening, and the fixed rod 14 is fixedly connected to the top of the sealing box 1; A fixed gear 13 is fixedly connected to the lower end of the fixed rod 14, and the outer side of the fixed gear 13 meshes with the planetary gear 11.

[0029] When hot air enters the sealed chamber 1 through the air inlet pipe 3, the air inlet pipe 3 and the sealed chamber 1 are tangentially distributed, so the hot air will come into contact with the guide strip 6 when entering the sealed chamber 1. The guide strip 6 is distributed in a spiral structure inside the sealed chamber 1, so the hot air will move spirally downward inside the sealed chamber 1, thereby achieving uniform heating and preventing excessive local temperature differences from affecting the drying efficiency of the electroplated parts.

[0030] Bearing balls 15 are installed on both the upper and lower sides of the upper end of the rotating sleeve 8, located at the connection between the rotating sleeve 8 and the fixed sleeve 7. During the rotation of the rotating sleeve 8, it will be supported by these two sets of bearing balls 15, thereby reducing rotational resistance and forming an effective bearing structure.

[0031] When the connecting rod 10 rotates with the rotating sleeve 8, it will cause the planetary gear 11 to rotate outside the fixed gear 13. Since the two mesh with each other, the rotation of the planetary gear 11 outside the fixed gear 13 will cause the planetary gear 11 to rotate, which in turn causes the bottom hook 12 to drive the electroplated part to rotate around the rotating sleeve 8 inside the sealed box 1, ensuring that the electroplated part is in full contact with the hot air and improving the drying efficiency.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
