Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology for metal parts, specifically, it relates to a part drying and baking device. Background Technology

[0002] During the production and processing of stamped copper sheets, they are typically oiled and polished, then cleaned with water to remove the oil and dirt from the surface before drying. Current drying processes for stamped copper sheets generally suffer from low drying efficiency, easy oxidation of the copper surface, and high energy consumption. Currently, the industry mainly uses two types of drying methods: one is to air-dry the stamped copper sheets naturally, and the other is to use drying equipment to dry the stamped copper sheets.

[0003] However, while both drying methods ultimately achieve the goal of drying stamped copper sheets, they both have significant drawbacks. Specifically, the natural drying method of air-drying stamped copper sheets relies on natural environmental conditions and requires an extremely long time, which undoubtedly delays the subsequent packaging process and affects the efficiency of the entire production process. When using drying equipment to dry stamped copper sheets, the sheets are directly exposed to a high-temperature drying environment. During this process, the copper sheets inevitably come into contact with oxygen in the air. Under high temperatures, copper readily reacts with oxygen, easily forming oxides such as copper oxide or cuprous oxide. Especially when the ambient humidity is high or the drying temperature distribution is uneven, the probability of this oxidation reaction increases significantly, ultimately making it difficult for the drying quality of the stamped copper sheets to meet the ideal standard. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a component drying and baking device.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] The device comprises an outer drying cylinder and an inner drying shell. The inner drying shell has several heat-conducting plates on one side. The outer drying cylinder has a drying channel for transporting stamped copper sheets. The top of the outer drying cylinder has a discharge port for the stamped copper sheets to enter the drying channel. A spiral feeding plate is installed inside the drying channel. An air outlet for blowing air into the inner drying shell is located between the drying channel and the spiral feeding plate. The outer drying cylinder transports the stamped copper sheets into the inner drying shell through the spiral feeding plate. The inner drying shell has a heating plate for heating the airflow and a stirring assembly for agitating the stamped copper sheets.

[0007] In this invention, the combination of an outer drying drum and an inner drying shell achieves integrated "air drying-drying". Compared with traditional processes, this method avoids oxidation of the stamped copper sheets, reduces the time required to dry the stamped copper sheets, and improves the drying efficiency and quality of the stamped copper sheets.

[0008] In this invention, the heat-conducting plate can transfer part of the temperature of the inner drying shell to the outer drying cylinder, thereby creating a low-temperature environment inside the drying channel, which accelerates the drying process of the stamped copper sheet and further improves the drying efficiency of the stamped copper sheet.

[0009] It should be noted that the temperature of the low-temperature environment is relative to the temperature inside the inner drying shell, and this low-temperature environment is usually slightly higher than the room temperature.

[0010] Preferably, the air outlet is located on one side of the material inlet, and a connecting plate frame is provided between the outer drying cylinder and the inner drying shell. One end of the connecting plate frame is connected to the inside of the drying channel, and the other end of the connecting plate frame is connected to the inside of the inner drying shell.

[0011] In this invention, air is blown into the drying channel through the air outlet, allowing the airflow to enter the inner drying shell along the drying channel and carry away the heat emitted by the heating plate. The stirring component agitates the stamped copper sheet to dry it, so that the airflow not only helps to dry the stamped copper sheet, but also serves as the drying gas for drying the stamped copper sheet in subsequent use, further improving the drying efficiency of the stamped copper sheet.

[0012] Preferably, the inner drying shell is provided with a drying chamber, the top of the drying chamber is provided with a waste heat recovery pipe, and the bottom of the drying chamber is fastened to a discharge plate.

[0013] In this invention, after the drying process is completed, the waste heat gas generated during the drying process will be recovered through a waste heat recovery pipe and discharged into a water tank used for cleaning the stamped copper sheets, which helps to carry out the cleaning process of the stamped copper sheets and avoids the waste of waste heat.

[0014] Preferably, the stirring assembly includes a stirring rod rotatably connected inside the drying chamber, and a drive motor is provided on one side of the inner drying shell, the drive motor being drivenly connected to the stirring rod.

[0015] Preferably, the stirring rod includes an arc-shaped pusher blade for accommodating the stamped copper sheet, and the arc-shaped pusher blade is provided with a pusher plate for pushing the stamped copper sheet to move.

[0016] Preferably, the heat-conducting plate is made of aluminum plate, and a shape memory alloy is provided on one side of the aluminum plate, and a triggerable heat insulation layer is provided on the side of the shape memory alloy away from the aluminum plate.

[0017] In this invention, by combining shape memory alloy with a triggerable heat insulation layer, when the temperature in the drying zone exceeds 60°C, the shape memory alloy undergoes a phase transformation, changing from a martensitic structure to an austenitic structure. This causes the volume to expand, which in turn drives the heat insulation layer to expand, increasing its thickness and internal air pores. This significantly reduces heat transfer, allowing the drying channel to maintain a stable low-temperature drying environment for a long time.

[0018] Compared with the prior art, the advantages of this utility model include:

[0019] (1) The component drying and drying device provided by this utility model achieves "drying-drying" integration by using an outer drying cylinder and an inner drying shell. Compared with traditional processes, it can reduce the time required to dry the stamped copper sheet while avoiding oxidation of the stamped copper sheet, and improve the drying efficiency and drying quality of the stamped copper sheet.

[0020] (2) The component drying and drying device provided by this utility model can transfer part of the temperature of the inner drying shell to the outer drying cylinder through the heat conduction plate, so that a low temperature environment is formed inside the drying channel, thereby accelerating the drying process of the stamped copper sheet and further improving the drying efficiency of the stamped copper sheet.

[0021] (3) The component drying and drying device provided by this utility model blows air into the drying channel through the air outlet, so that the airflow enters the inner drying shell along the drying channel and carries away the heat emitted by the heating plate. The stirring component stirs the stamped copper sheet to dry it, so that the airflow not only helps to dry the stamped copper sheet, but also can be used as the drying gas for drying the stamped copper sheet in subsequent use, further improving the drying efficiency of the stamped copper sheet.

[0036] This utility model embodiment is intended to introduce and explain the structural composition of a parts drying and drying device and the cooperation relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components in the parts drying and drying device in this utility model embodiment can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0037] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions. Example 1

[0038] Please see Figure 1 and Figure 2 A component drying and drying device includes an outer drying cylinder 1 and an inner drying shell 2.

[0039] Specifically, the outer drying cylinder 1 is provided with a drying channel 11 for transporting stamped copper sheets. The top of the outer drying cylinder 1 is provided with a feeding port 4 for the stamped copper sheets to enter the drying channel 11. A spiral feeding plate 10 is fixedly installed in the drying channel 11. An air outlet 6 for blowing air into the inner drying shell 2 is provided between the drying channel 11 and the spiral feeding plate 10. The air outlet 6 is fixedly installed on one side of the feeding port 4. The outer drying cylinder 1 transports the stamped copper sheets into the inner drying shell 2 through the spiral feeding plate 10. The inner drying shell 2 is provided with a heating plate 15 for heating the airflow. The inner drying shell 2 is provided with a stirring assembly for stirring the stamped copper sheets.

[0040] It should be noted that the spiral feed plate 10 has multiple drainage holes, through which the moisture from the stamped copper sheet can fall. The outer drying cylinder 1 is equipped with a fan, and the fan outlet is connected to the air outlet 6. By starting the fan, flowing air is drawn into the air outlet 6, and flowing air can be sprayed out from the air outlet 6.

[0041] Please see Figure 1 , Figure 2 and Figure 3 The inner drying shell 2 has several heat-conducting plates 7 on one side, and the inner drying shell 2 transfers heat to the interior of the outer drying cylinder 1 through the several heat-conducting plates 7.

[0042] In this embodiment, the heat-conducting plate 7 is made of aluminum plate, and a shape memory alloy, specifically a shape memory alloy wire, is fixedly disposed on one side of the aluminum plate. A triggerable heat insulation layer is fixedly disposed on the side of the shape memory alloy away from the aluminum plate. In other embodiments, the shape memory alloy is specifically a shape memory alloy sheet, and the shape memory alloy sheets are evenly distributed on the aluminum plate.

[0043] The shape memory alloy uses a nickel-titanium alloy with a one-way shape memory effect as the trigger element for the heat insulation layer. The heat insulation layer material is usually a high-efficiency heat insulation material such as ceramic fiber felt. At room temperature, the heat insulation layer is in a relatively compact state, allowing moderate heat transfer to preheat the air entering the outer cavity. When the temperature of the drying area of ​​the inner drying shell 2 exceeds 60°C, the shape memory alloy undergoes a phase transformation, changing from a martensitic structure to an austenitic structure. The volume expands, driving the heat insulation layer to expand, increasing its thickness and internal air porosity, thereby significantly reducing heat transfer. This allows the inner drying shell 2 to form a high temperature while the outer drying cylinder 1 can maintain a low-temperature environment for a long time.

[0044] It should be noted that the specific temperature of the low-temperature environment in the drying channel 11 is between 5℃ and 30℃, while the temperature of the drying area in the inner drying shell 2 is between 40℃ and 70℃. Specifically, the temperature inside the inner drying shell 2 can be controlled by adding a temperature controller to the parts drying and drying device and connecting it to the heating plate 15. The heating plate 15 is equipped with an electric heating wire, which generates heat when energized.

[0045] A connecting plate frame 16 is fixedly installed between the outer drying cylinder 1 and the inner drying shell 2. One end of the connecting plate frame 16 is connected to the inside of the drying channel 11, and the other end of the connecting plate frame 16 is connected to the inside of the inner drying shell 2.

[0046] Please see Figure 4 , Figure 5 and Figure 6 The inner drying shell 2 contains a drying chamber 12. A waste heat recovery pipe 3 is fixedly installed at the top of the drying chamber 12, and a vacuum pump is connected to the waste heat recovery pipe 3. The vacuum pump can extract and recover the waste heat gas inside the inner drying shell 2 for reuse. A discharge plate 5 is connected to the bottom of the drying chamber 12. One end of the discharge plate 5 is rotatably connected to the bottom of the inner drying shell 2, and the other end of the discharge plate 5 is threaded with a bolt. The discharge plate 5 is fastened to the bottom of the inner drying shell 2 by screwing the bolt into the inner drying shell 2. After the stamped copper sheet is dried, the bolt can be unscrewed and the discharge plate 5 can be rotated to open it and take it out. The stirring assembly includes a stirring rod 9 rotatably connected in the drying chamber 12. A drive motor 8 is fixedly installed on one side of the inner drying shell 2. A drive shaft 14 is fixedly connected to the drive end of the drive motor 8. The drive shaft 14 is fixedly connected to the stirring rod 9, so that when the drive motor 8 is started, its drive end can drive the stirring rod 9, causing the stirring rod 9 to rotate. The stirring rod 9 includes an arc-shaped pusher blade 13 for accommodating the stamped copper sheet. The end of the arc-shaped pusher blade 13 away from the drive shaft 14 is fixedly provided with a pusher plate for pushing the stamped copper sheet to move. When the stirring rod 9 rotates, the pusher plate can push the stamped copper sheet, and then the arc-shaped pusher blade 13 can drive the stamped copper sheet to move, thereby achieving the purpose of stirring the stamped copper sheet to move.

[0047] In this embodiment, the steps of air-drying and baking the stamped copper sheet are as follows:

[0048] S1. The stamped copper sheet that needs to be dried is put into the drying channel 11 through the feeding port 4. The stamped copper sheet slides from the top of the spiral feeding plate 10 to the bottom of the spiral feeding plate 10 by its own weight. At the same time, the fan is started to draw the flowing air into the air outlet 6, and the flowing air can be sprayed out from the air outlet 6.

[0049] S2. The heating plate 15 is powered on and heated to increase the temperature inside the inner drying shell 2. The temperature is transferred to the drying channel 11 through the heat conduction plate 7, so that the drying channel 11 is in a low temperature environment. The stamped copper sheet moves in the low temperature environment, which will produce a drying effect.

[0050] S3. When the stamped copper sheet passes through the spiral feed plate 10 and the connecting plate frame 16 into the inner drying shell 2, the flowing gas also enters the inner drying shell 2 and carries away the heat generated by the heating plate 15, blowing it onto the stamped copper sheet inside the inner drying shell 2. The drive motor 8 starts, causing the stirring rod 9 to rotate and stir the stamped copper sheet as it moves inside the inner drying shell 2 for drying. After drying, the bolt on the discharge plate 5 is unscrewed from the inner drying shell 2, and the dried stamped copper sheet can be taken out by rotating and opening the discharge plate 5.

[0051] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
