Technical Field
[0001] This application relates to the field of drying equipment technology, and in particular to a drying equipment for electroplated products. Background Technology
[0002] Electroplating is a process that uses electrolysis to deposit a layer of another metal or alloy onto a metal surface, and it is widely used in industrial manufacturing. Its main functions include preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. Electroplating is a wet process; after electroplating, plating solution remains on the workpiece surface. Therefore, it needs to be rinsed with clean water and further dried to ensure the quality and performance of the electroplated parts. Drying is a crucial post-plating treatment step, directly affecting the surface quality and subsequent performance of the electroplated parts.
[0003] Currently, the drying of electroplated parts typically employs a drying oven combined with a heating device and a fan. The specific operation involves placing the cleaned electroplated parts into the drying oven, heating the air using the heating device, and then using a fan to blow the hot air onto the electroplated parts to achieve the drying purpose. This method relies on the flow of hot air and contact with the surface of the electroplated parts to achieve the effect of evaporating moisture.
[0004] Traditional methods of drying electroplated parts typically involve stacking the parts and concentrating the hot air blowing in certain areas. This results in some parts not being able to fully contact the hot air, leading to uneven heat distribution and surface defects that affect the performance and lifespan of the parts. Utility Model Content
[0005] The purpose of this application is to provide an electroplating product drying device to address the problem that traditional electroplating drying methods often result in some electroplated parts not being able to fully contact the hot air, leading to uneven heat distribution, which in turn causes defects on the surface of the electroplated parts and affects their performance and service life.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A drying device for electroplated products includes a drying drum with a top cover hinged to the top. A heating box is fixedly connected to one side of the drying drum. An air guide pipe adapted to the output end of the heating box is fixedly connected to the top of the top cover. A blower is fixedly connected to the input end of the heating box. Multiple electric heating wires are uniformly fixedly connected inside the blower. A draining inner cylinder is rotatably connected inside the drying drum. A drying bag is installed inside the draining inner cylinder. One end of the draining inner cylinder passes through the drying drum and is fixedly connected to a first gear. A second gear meshing with the first gear is rotatably connected to the bottom of the drying drum. A rotary motor is fixedly connected to the bottom of the drying drum. The output end of the rotary motor is fixedly connected to the second gear. A drain pipe is fixedly connected to the bottom of the drying drum. A locking assembly is installed at one end of the drying bag.
[0008] By adopting the above technical solution, and through the coordinated use of the locking components, air guide pipe, blower, electric heating wire, and draining inner cylinder, it is convenient to start the rotary motor to drive the second gear to mesh with the first gear when hot air is introduced into the drying bag by starting the blower and electric heating wire. This causes the draining inner cylinder to drive the drying bag and the electroplated parts inside to rotate rapidly, thereby ensuring full contact between the hot air and the electroplated parts inside the drying bag. This achieves rapid drying of the electroplated parts inside the drying bag. Then, the water vapor generated inside the drying drum is discharged through the drain pipe. This ensures full contact between the hot air and the electroplated parts, effectively improving the drying efficiency of the electroplated parts and enhancing their performance and service life.
[0009] Furthermore, the fastening assembly includes a fastening ring fixedly connected to the top of the drying bag, one end of which is uniformly fixedly connected with a plurality of elastic buckles, and the top of the draining inner cylinder is provided with a plurality of slots adapted to the elastic buckles, and the inner side of the slots is symmetrically provided with grooves adapted to the elastic buckles.
[0010] By adopting the above technical solution, and by setting up the cooperation between the elastic buckle and the slot, it is convenient to use the elastic buckle to quickly snap and fix the drying bag and the draining inner cylinder when the traction locking ring pulls the drying bag into the draining inner cylinder and the elastic buckle is inserted into the slot. The elastic buckle is then snapped back into the slot by utilizing its elastic properties, thereby achieving quick snap-fit and fixation of the drying bag and the draining inner cylinder, which effectively improves the practicality of the device.
[0011] Furthermore, the bottom of the draining inner cylinder is provided with an annular inner conical groove, and the bottom of the annular inner conical groove is provided with a plurality of drainage holes evenly distributed.
[0012] By adopting the above technical solution, and by using the combination of the annular inner conical groove and the drainage hole, it is easy to guide the water vapor accumulated at the bottom of the drain cylinder through the drainage hole and discharge it from the inside of the drain cylinder, which effectively reduces the problem of water vapor accumulation inside the drain cylinder and affecting the drying efficiency of electroplated parts.
[0013] Furthermore, the top of the drying drum is provided with an annular inner arc groove, and the top of the draining inner cylinder is fixedly connected with an annular slider. The outer periphery of the annular slider is spherically hinged with multiple balls, and the balls roll against the inner wall of the annular inner arc groove.
[0014] By adopting the above technical solution, and by setting the ball bearings and the annular inner arc groove to work together, one end of the drain inner cylinder forms a rolling contact with the inner wall of the annular inner arc groove through the ball bearings, thereby effectively improving the rotational stability of the drain inner cylinder.
[0015] Furthermore, a corrugated pipe is fixedly connected to one end of the air guide pipe, and one end of the corrugated pipe is fixedly connected to the output end of the heating box. A traction spring is fixedly connected to the inner side of the corrugated pipe, and the bottom of the traction spring is fixedly connected to the heating box.
[0016] By adopting the above technical solution, and by setting the bellows and traction spring to work together, the bellows and traction spring can be pulled to deform as the air guide pipe moves, thereby effectively improving the sealing effect between the air guide pipe and the heating box.
[0017] Furthermore, multiple guide plates are uniformly and fixedly connected inside the blower, and the electric heating wire is fixedly connected to the bottom of the guide plate. Adjacent guide plates are arranged alternately to form an airflow duct.
[0018] By adopting the above technical solution, and by using the air duct and electric heating wire in combination, the travel distance of the air through the heating box is effectively extended, thereby making the contact between the air and the electric heating wire more sufficient and effectively improving the heating efficiency of the device.
[0019] Furthermore, a filter screen is fixedly connected to the input end of the blower.
[0020] By adopting the above technical solution, the air drawn into the heating box by the blower can be intercepted and filtered by setting up a filter screen, so as to reduce the adhesion of dust and other foreign objects in the air to the surface of the electroplated parts and improve the practicality of the device.
[0021] Furthermore, a conical support is fixedly connected to the bottom of the drying drum, and multiple rubber pads are evenly fixedly connected to the bottom of the conical support.
[0022] By adopting the above technical solution, and by using the combination of conical support and rubber pads, the drying drum forms a flexible contact with the ground through the rubber pads, which effectively reduces the vibration transmission between the drying drum and the ground and improves the stability of the device.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. By setting up a locking assembly in conjunction with the air duct, blower, electric heating wire, and draining inner cylinder, it is convenient to start the rotary motor to drive the second gear to mesh with the first gear when the blower and electric heating wire are started to input hot air into the drying bag. This causes the draining inner cylinder to drive the drying bag and the electroplated parts inside to rotate rapidly, thereby ensuring full contact between the hot air and the electroplated parts inside the drying bag. This achieves rapid drying of the electroplated parts inside the drying bag. Then, the water vapor generated inside the drying drum is discharged through the drain pipe. This ensures full contact between the hot air and the electroplated parts, effectively improving the drying efficiency of the electroplated parts and improving their performance and service life.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0033] This application discloses an electroplating product drying device.
[0034] Reference Figure 1 - Figure 3A drying device for electroplated products includes a drying drum 1, a top cover 2 hinged to the top of the drying drum 1, a heating box 3 fixedly connected to one side of the drying drum 1, an air guide pipe 4 adapted to the output end of the heating box 3 fixedly connected to the top of the top cover 2, a blower 5 fixedly connected to the input end of the heating box 3, multiple electric heating wires 6 evenly fixedly connected inside the blower 5, a draining inner cylinder 7 rotatably connected inside the drying drum 1, a drying bag 8 installed inside the draining inner cylinder 7, one end of the draining inner cylinder 7 passing through the drying drum 1 and fixedly connected to a first gear 9, a second gear 10 meshing with the first gear 9 rotatably connected to the bottom of the drying drum 1, a rotary motor 11 fixedly connected to the bottom of the drying drum 1, the output end of the rotary motor 11 fixedly connected to the second gear 10, a drain pipe 12 fixedly connected to the bottom of the drying drum 1, and a locking component installed at one end of the drying bag 8.
[0035] The fastening assembly includes a fastening ring 13 fixedly connected to the top of the drying bag 8. One end of the fastening ring 13 is evenly fixedly connected with multiple elastic buckles 14. The top of the draining inner cylinder 7 is provided with multiple slots 15 that are adapted to the elastic buckles 14. The inner side of the slots 15 is symmetrically provided with slots 16 that are adapted to the elastic buckles 14.
[0036] Furthermore, the bottom of the drain inner cylinder 7 is provided with an annular inner conical groove 17, and the bottom of the annular inner conical groove 17 is provided with a plurality of drainage holes 18 evenly distributed.
[0037] Furthermore, the top of the drying drum 1 is provided with an annular inner arc groove 19, and the top of the draining inner cylinder 7 is fixedly connected with an annular slider 20. The outer sphere of the annular slider 20 is hinged with multiple balls 21, and the balls 21 roll against the inner wall of the annular inner arc groove 19.
[0038] Furthermore, a filter screen 25 is fixedly connected to the input end of the blower 5;
[0039] Furthermore, a conical support 26 is fixedly connected to the bottom of the drying drum 1, and multiple rubber pads 27 are evenly fixedly connected to the bottom of the conical support 26.
[0040] In use, first open the top cover 2 around the hinge shaft, and pull the locking ring 13 to move the drying bag 8 into the inside of the draining inner cylinder 7. At the same time, pull the elastic buckle 14 into the inside of the slot 15, so that the elastic buckle 14 is deformed by force and springs back into the inside of the slot 16, thereby completing the quick fixing and installation of the drying bag 8. Then, pour the electroplated parts into the inside of the drying bag 8, and close the top cover 2 around the hinge shaft. At the same time, start the blower 5 and the electric heating wire 6, so that the blower 5 draws the external air through the heating box 3 and the air guide pipe 4 into the inside of the drying barrel 1. The air drawn by the blower 5 is intercepted and filtered by the filter screen 25 to reduce the dust and other foreign objects in the air from adhering to the surface of the electroplated parts. When the air passes through the inside of the heating box 3, it is heated by the contact of the electric heating wire 6, so that the air is heated into hot air and enters the inside of the drying bag 8.
[0041] Then, when hot air is introduced into the interior of the drying bag 8 through the air duct 4, the second gear 10 is driven to mesh with the first gear 9 by starting the rotary motor 11, and the first gear 9 drives the inner drain cylinder 7 to rotate. At the same time, the inner drain cylinder 7 drives the annular slider 20 to push the ball 21 to roll along the inner wall of the annular inner arc groove 19. This causes the inner drain cylinder 7 to drive the drying bag 8 and the electroplated parts inside to rotate rapidly, so that the electroplated parts inside the drying bag 8 come into full contact with the hot air and the residual moisture on the surface of the electroplated parts is dried.
[0042] Next, the hot air, after contacting the electroplated parts, carries moisture through the inner drain cylinder 7 and is discharged from the drying drum 1 through the drain pipe 12. At the same time, water droplets that have accumulated at the bottom of the inner drain cylinder 7 due to gravity slide down into the inner conical groove 17 under the influence of gravity, and flow into the bottom of the drying drum 1 through the drain hole 18, and then are discharged through the drain pipe 12. This effectively improves the full contact between the electroplated parts and the hot air, achieving thorough drying of the electroplated parts inside the drying bag 8, effectively improving the drying efficiency of the device, and improving the performance and service life of the electroplated parts. At the same time, the use of the conical support 26 and the rubber pad 27 effectively increases the support area at the bottom of the drying drum 1, and the conical support 26 forms a flexible contact with the ground through the rubber pad 27, effectively reducing the vibration transmission between the drying drum 1 and the ground, and improving the stability of the device.
[0043] Reference Figure 1 and Figure 2 , Figure 4 One end of the air duct 4 is fixedly connected to a bellows 22, one end of the bellows 22 is fixedly connected to the output end of the heating box 3, and a traction spring 23 is fixedly connected to the inner side of the bellows 22. The bottom of the traction spring 23 is fixedly connected to the heating box 3.
[0044] In use, when the top cover 2 is opened around the hinge shaft, the top cover 2 causes the air guide pipe 4 to pull the bellows 22 to extend, thereby lengthening the bellows 22. At the same time, the bellows 22 causes the traction spring 23 to extend and deform. Then, when the top cover 2 is closed around the hinge shaft, the traction spring 23 is released from its force and rebounds, pulling the bellows 22 to compress, thereby shortening the length of the bellows 22. This effectively improves the sealing effect between the air guide pipe 4 and the heating box 3, and enhances the practicality of the device.
[0045] Reference Figure 1 and Figure 2 , Figure 4 The blower 5 has multiple guide plates 24 evenly and fixedly connected inside. The electric heating wire 6 is fixedly connected to the bottom of the guide plate 24. Adjacent guide plates 24 are arranged alternately to form a duct for airflow.
[0046] When in use, when the blower 5 is started to draw air through the interior of the heating box 3, the air flows along the airflow channel formed between multiple guide plates 24, thereby effectively extending the travel distance of the air through the interior of the heating box 3, and ensuring full contact with multiple electric heating wires 6 during the airflow process, thus effectively improving the heating efficiency of the device.
[0047] The implementation principle of the electroplating product drying device in this embodiment is as follows: First, the top cover 2 is opened around the hinge shaft, so that the top cover 2 drives the air guide pipe 4 to pull the corrugated pipe 22 to extend, thereby lengthening the corrugated pipe 22. At the same time, the corrugated pipe 22 drives the traction spring 23 to extend and deform, and pulls the locking ring 13 to pull the drying bag 8 into the inside of the drain inner cylinder 7. At the same time, the elastic buckle 14 is pulled to insert into the inside of the slot 15, so that the elastic buckle 14 is deformed by force and springs back into the inside of the slot 16, thereby completing the quick fixing and installation of the drying bag 8.
[0048] Then, the electroplated parts are poured into the inside of the drying bag 8, and the top cover 2 is closed around the hinge shaft, so that the traction spring 23 is released from the force and produces a rebound deformation, and pulls the bellows 22 to perform a compression movement, thereby shortening the length of the bellows 22. At the same time, the blower 5 and the electric heating wire 6 are started, so that the blower 5 draws the external air through the heating box 3 and the air guide pipe 4 and introduces it into the inside of the drying barrel 1.
[0049] Meanwhile, as the air passes through the interior of the heating chamber 3, it flows along the airflow channel formed between multiple guide plates 24, thereby effectively extending the travel distance of the air through the interior of the heating chamber 3. During the process of the air flowing along the airflow channel, it comes into full contact with multiple electric heating wires 6, so that the air is heated into hot air and enters the interior of the drying bag 8.
[0050] Next, when hot air is introduced into the drying bag 8 through the air duct 4, the rotating motor 11 is started to drive the second gear 10 to mesh with the first gear 9, and the first gear 9 drives the inner drain cylinder 7 to rotate. At the same time, the inner drain cylinder 7 drives the annular slider 20 to push the ball 21 to roll along the inner wall of the annular inner arc groove 19. This causes the inner drain cylinder 7 to drive the drying bag 8 and the electroplated parts inside to rotate rapidly. This allows the electroplated parts inside the drying bag 8 to come into full contact with the hot air, drying the residual moisture on the surface of the electroplated parts. Then, the hot air that has come into contact with the electroplated parts carries the moisture through the inner drain cylinder 7 and is discharged into the drying barrel 1 through the drain pipe 12.
