Description

Technical Field

[0001] This utility model specifically relates to an electroplating drying device. Background Technology

[0002] In the electroplating industry, workpieces require drying after electroplating to remove residual plating solution and ensure coating quality and adhesion. Existing electroplating drying equipment often uses a fixed duct structure, directly supplying hot air into the inner cavity for drying. However, this method has the following drawbacks: the fixed duct's air outlet direction is singular, and hot air can only cover a localized area of ​​the workpiece. This results in the workpiece drying too quickly near the duct and insufficiently drying areas further away, easily leading to quality problems such as coating cracking and color differences. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide an electroplating drying device. An electroplating drying device includes an inner cylinder and an outer cylinder, with an annular mounting cavity enclosing the inner and outer cylinders.

The inner cylinder has a plurality of first ventilation holes evenly distributed around its circumference that communicate with the annular mounting cavity. The cavity has a plurality of second ventilation holes evenly distributed around its circumference that communicate with the inner cavity of the inner cylinder. A duct capable of rotating about the central axis of the inner cylinder is installed within the annular mounting cavity. The installation cavity is equipped with a motor that can drive the air duct to rotate; the air duct includes a first vertical pipe, a second vertical pipe and a horizontal pipe connecting the first vertical pipe and the second vertical pipe. The first vertical pipe is located in the cavity, the second vertical pipe is located on the outer periphery of the inner cylinder, a first air outlet facing the second ventilation hole is opened on one side of the first vertical pipe, a second air outlet facing the first ventilation hole is opened on one side of the second vertical pipe, and a heater is provided on one side of the outer cylinder. The air outlet of the heater is connected to the first vertical pipe through a rotary joint.

[0004] In one embodiment, the opening of the inner cylinder has a recessed groove along the circumference to facilitate the hanging of a basket inside the inner cylinder.

[0005] In one embodiment, a cover plate is removably placed over the upper opening of the inner cylinder.

[0006] In one embodiment, a temperature sensor is provided on the inner side of the cover plate, and a controller is provided on the outer side of the outer cylinder. The temperature sensor is electrically connected to the controller, and the controller is electrically connected to the heater. The temperature sensor can detect the temperature of the inner cavity of the inner cylinder and transmit the signal to the controller. The controller can adjust the air outlet temperature of the heater according to the temperature signal.

[0007] In one embodiment, the bottom of the outer cylinder is provided with a plurality of casters, and the casters are provided with brake pads.

[0008] In one embodiment, both the inner and outer cylinders are made of stainless steel, and the inner wall of the inner cylinder is coated with a high-temperature resistant, non-stick coating.

[0009] In summary, the advantages of this utility model over the prior art are: This utility model of a warm air blower is directly connected to the air duct via a rotary joint.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 3 The present invention preferably provides an electroplating drying device, comprising an inner cylinder 1 and an outer cylinder 2, with an annular mounting cavity 3 enclosing the inner cylinder 1 and the outer cylinder 2. The inner cylinder 1 has a central column 4, with a cavity 5 recessed at its lower end that communicates with the annular mounting cavity 3, and a mounting cavity 6 recessed at its upper end. The inner cylinder 1 has a plurality of first ventilation holes 7 evenly distributed around its circumference that communicate with the annular mounting cavity 3. The cavity 5 has a plurality of second ventilation holes 8 evenly distributed around its circumference that communicate with the inner cavity of the inner cylinder 1. The annular mounting cavity 3 is provided with a fan that can rotate about the central axis of the inner cylinder 1. The installation cavity 6 is equipped with a motor 10 that can drive the air duct 9 to rotate; the air duct includes a first vertical pipe 91, a second vertical pipe 92 and a horizontal pipe 93 connecting the first vertical pipe 91 and the second vertical pipe 92. The first vertical pipe 91 is located in the cavity 5, and the second vertical pipe 92 is located on the outer periphery of the inner cylinder 1. The first vertical pipe 91 has a first air outlet 94 facing the second ventilation hole 8 on one side, and the second vertical pipe 92 has a second air outlet 95 facing the first ventilation hole 7 on one side. The outer cylinder 2 is equipped with a heater 96, and the air outlet of the heater 96 is connected to the first vertical pipe 91 through a rotary joint.

[0012] Specifically, the warm air blower is a relatively mature existing technology, and its structural principle will not be elaborated here. It simply needs to provide warm air into the duct. The duct is integrally formed from a first vertical pipe, a second vertical pipe, and a horizontal pipe, and is made of high-temperature resistant stainless steel. The first vertical pipe is vertically installed inside the cavity of the column, and its side wall has a first air outlet facing a second ventilation hole, ensuring that hot air can enter the inner cavity of the inner cylinder through the second ventilation hole. The second vertical pipe is vertically installed inside the outer periphery of the inner cylinder (within the annular mounting cavity), and its side wall has a second air outlet facing the first ventilation hole, ensuring that hot air can enter the inner cavity of the inner cylinder through the first ventilation hole. The horizontal pipe is horizontally installed, with both ends connected to the middle of the first and second vertical pipes, forming a "U"-shaped air duct. The motor is fixedly installed in the mounting cavity of the column, and its output shaft is fixedly connected to the upper end of the first vertical pipe through a coupling. It can drive the air duct to rotate at a constant speed around the central axis of the column. The warm air blower is fixedly installed on the outer wall of the outer cylinder, and its air outlet is connected to the lower end of the first vertical pipe through a rotary joint. The rotary joint can ensure that the hot air is stably delivered without leakage when the air duct rotates.

[0013] Furthermore, multiple rollers (not shown in the figure) are rotatably arranged at intervals along the length of the horizontal pipe on its lower side, and the multiple rollers (not shown in the figure) can be movably supported against the bottom of the annular mounting cavity to form a movable support for the air duct.

[0014] Furthermore, the inner cylinder 1 has a recessed groove (not shown in the figure) along its circumference at the opening, which facilitates the hanging of a basket inside the inner cylinder 1. The hooks of the external hanging basket can then be engaged in the recessed groove for positioning and to prevent displacement. Electroplated parts requiring drying can be placed in the hanging basket first, and then placed inside the inner cylinder for drying.

[0015] Furthermore, a cover plate 12 is detachably placed over the upper opening of the inner cylinder 1. The cover plate is made of stainless steel and is detachably connected to the upper opening of the inner cylinder via a snap-fit ​​structure.

[0016] Furthermore, a temperature sensor 13 is provided on the inner side of the cover plate 12, and a controller (not shown in the figure) is provided on the outer side of the outer cylinder 2. The temperature sensor 13 is electrically connected to the controller (not shown in the figure), and the controller (not shown in the figure) is electrically connected to the heater 96. The temperature sensor 13 can detect the temperature of the inner cavity of the inner cylinder 1 and transmit the signal to the controller (not shown in the figure). The controller (not shown in the figure) can adjust the air outlet temperature of the heater 96 according to the temperature signal. Specifically, the temperature sensor detects the temperature of the inner cavity of the inner cylinder in real time and transmits the signal to the controller; if the temperature is lower than the set value, the controller controls the heater to increase the air outlet temperature; if the temperature is higher than the set value, the controller controls the heater to decrease the air outlet temperature to ensure the stability of the inner cavity temperature.

[0017] Furthermore, the bottom of the outer cylinder 2 is provided with several casters (not shown in the figure), and each caster (not shown in the figure) is provided with a brake pad (not shown in the figure). If it is necessary to move the device, release the brake pads of the casters, push the device to the target position, and then lock the brake pads.

[0018] Furthermore, both the inner cylinder 1 and the outer cylinder 2 are made of stainless steel, and the inner wall of the inner cylinder 1 is coated with a high-temperature resistant and non-stick coating. The inner and outer cylinders are made of stainless steel, which is corrosion-resistant and high-temperature resistant; the high-temperature resistant and non-stick coating on the inner wall of the inner cylinder can prevent electroplating residue from sticking, reduce cleaning difficulty, and extend the overall service life of the device.
