Description

Technical Field

[0001] This utility model relates to the field of cover plate coating drying technology, specifically a thin film cooling coating drying device. Background Technology

[0002] The main purpose of drying the coating on mobile phone glass covers is to remove solvents from the coating and allow it to cure. After solution coating, the coating contains a large amount of solvents, such as organic or aqueous solvents. If these solvents are not removed, the coating will remain in a liquid or semi-liquid state and cannot form a stable solid film. Moreover, the presence of solvents will affect many properties of the coating, such as optical properties and adhesion.

[0003] Existing technologies lack a structure for slow-speed warm air blowing at the inlet and outlet of the drying equipment. As a result, existing drying devices use a conveyor belt to send the cover plate into the drying equipment for drying. During this process, dust in the air can easily enter the drying hood and affect the coating. Furthermore, due to the high drying temperature, there is a certain probability that the cover plate will crack due to the large temperature difference when it is directly removed from the drying hood after being heated. Based on the shortcomings of existing technologies, this utility model designs a thin-film cooling coating drying device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a thin-film cooling coating drying device, which has the advantage of slow warm air blowing at the inlet and outlet of the drying equipment.

[0005] This utility model provides the following technical solution: a thin film cooling coating drying device, including a conveyor, a drying hood is fixedly connected to the upper surface of the conveyor, and air blowing mechanisms are provided at both ends inside the drying hood to facilitate dust prevention and warm air blowing.

[0006] The air blowing mechanism includes a wind box, a wind hood, an air inlet pipe, a fan unit, a heat-conducting copper pipe, heat-conducting fins, heat-dissipating fins, and an air outlet pipe. The wind box is fixedly connected to both ends of the inner wall of the drying hood. The wind hood is fixedly connected to the upper surface of the wind box. The air inlet pipe is fixedly connected to the upper surface of the wind hood. The fan unit is fixedly connected to the other end of the air inlet pipe, and a dust filter plate assembly is installed inside the fan unit. The heat-conducting copper pipe is fixedly connected to one side of the wind box. The heat-conducting fins are fixedly connected to the heat-conducting copper pipe. The heat-dissipating fins are fixedly connected to the heat-conducting copper pipe inside the wind box. The air outlet pipe is fixedly connected to the bottom of the wind box.

[0007] As a preferred embodiment of this utility model, the conveyor is internally rotatably connected to a transmission belt, and the bottom of the conveyor is fixedly connected to a support leg.

[0008] As a preferred embodiment of this utility model, a temperature controller is fixedly connected to the upper surface of the drying hood, a connecting rod is fixedly connected to the top of the inner cavity of the drying hood, a heat insulation cover is fixedly connected to the bottom of the connecting rod, and a heating wire is fixedly installed inside the heat insulation cover.

[0009] In a preferred embodiment of this invention, the conveyor belt is rotatably connected to the bottom of the drying hood.

[0010] As a preferred embodiment of this invention, the heating wire is connected to the temperature control electromechanical system.

[0011] As a preferred embodiment of this utility model, the fan unit is fixedly connected to the upper surface of the drying hood, and the air inlet pipe is fixedly connected to the drying hood through it.

[0012] As a preferred embodiment of this utility model, the air outlet pipe blows air towards the outer end of the drying hood, and the inner cavities of the air box, air hood, air inlet pipe, and air outlet pipe are connected.

[0013] As a preferred embodiment of this invention, the temperature-conducting fins are disposed inside the drying hood.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This thin-film refrigeration coating drying device controls the heating coil to reach the preset temperature via a temperature controller. Then, a coated glass cover is placed on a conveyor belt and moved into the drying hood. At this time, two sets of fans are activated to draw outside air into the air inlet pipe, which then enters the air box through the air hood. The air box is equipped with heat-conducting copper pipes, which are connected to both heat-dissipating and heat-conducting fins on both the inner and outer sides. Because the heat-conducting fins are close to the heating coil, they also heat up due to heat radiation after the heating coil heats up, and the temperature is transferred through heat conduction. The copper tube transfers heat to the heat dissipation fins. At this time, the flowing air entering the air box undergoes heat exchange with the heat dissipation fins, causing the high-temperature air to slowly blow out from the air outlet. The cover plate about to enter the drying hood is slowly preheated by the hot air flowing above it before entering the drying hood to wait for drying. After the dried cover plate is removed from the drying hood, the high-temperature airflow will blow above the cover plate for a period of time to effectively prevent a sudden drop in temperature. This device helps to prevent external dust from entering the drying hood and prevents the ambient temperature from rising or falling suddenly when the cover plate enters or leaves.

A conveyor belt 101 is rotatably connected inside the conveyor 1, and a support leg 102 is fixedly connected to the bottom of the conveyor 1. The conveyor belt 101 is rotatably connected below the drying hood 2.

[0024] Please see Figure 2-3 A temperature controller 201 is fixedly connected to the upper surface of the drying hood 2. A connecting rod 202 is fixedly connected to the top of the inner cavity of the drying hood 2. A heat insulation cover 203 is fixedly connected to the bottom of the connecting rod 202. A heating wire 204 is fixedly installed inside the heat insulation cover 203. The heating wire 204 is electrically connected to the temperature controller 201.

[0025] By setting a temperature controller 201 and a heating rod 204, the cover plate on the conveyor belt 101 is dried. By setting a drying hood 2, a connecting rod 202 and a heat insulation hood 203, heat loss is prevented while the heating rod 204 can be fixed inside the drying hood 2.

[0026] Please see Figure 3-5The air blowing mechanism 3 includes an air box 301, an air hood 302, an air inlet pipe 303, a fan unit 304, a heat-conducting copper pipe 305, heat-conducting fins 306, heat-dissipating fins 307, and an air outlet pipe 308. The air box 301 is fixedly connected to both ends of the inner wall of the drying hood 2. The air hood 302 is fixedly connected to the upper surface of the air box 301. The air inlet pipe 303 is fixedly connected to the upper surface of the air hood 302. The fan unit 304 is fixedly connected to the other end of the air inlet pipe 303, and a dust filter plate assembly is installed inside the fan unit 304. The heat-conducting copper pipe 305 passes through and is fixedly connected to the air outlet pipe 308. On one side of the air box 301, the heat-conducting fins 306 are fixedly connected to the heat-conducting copper pipe 305, the heat-dissipating fins 307 are fixedly connected to the heat-conducting copper pipe 305 inside the air box 301, the air outlet pipe 308 is fixedly connected to the bottom of the air box 301, the fan unit 304 is fixedly connected to the upper surface of the drying hood 2, the air inlet pipe 303 is fixedly connected to the drying hood 2, the air outlet pipe 308 blows air towards the outer end of the drying hood 2, the inner cavities of the air box 301, the air hood 302, the air inlet pipe 303 and the air outlet pipe 308 are connected, and the heat-conducting fins 306 are arranged inside the drying hood 2.

[0027] By setting up an air box 301, an air hood 302, an air inlet pipe 303, a fan unit 304, and an air outlet pipe 308, and by installing a dust filter plate assembly inside the fan unit 304, external air is filtered before entering the air inlet pipe 303, the air hood 302, and the air box 301, and then blown out through the air outlet pipe 308, preventing external dust from floating into the drying hood 2. By setting up a heat-conducting copper pipe 305, a heat-conducting fin 306, and a heat-dissipating fin 307, the heat-conducting fin 306 receives the temperature and transfers it to the heat-dissipating fin 307 through the heat-conducting copper pipe 305, thereby heating the air entering the air box 301. This allows the blown-out air to preheat the cover plate that is about to enter the drying hood 2 for drying and to provide heat preservation and slow cooling treatment for the cover plate that has been dried.

[0028] Working principle: When a thin film cooling coating drying device is used, in the initial state, the conveyor belt 101 is first rotated and connected to the conveyor 1. The heat insulation cover 203 and the heating wire column 204 are installed in the drying hood 2 set on the top of the conveyor 1 through the connecting top rod 202, so as to dry the cover plate coating. The heat-conducting copper pipe 305, heat-conducting fins 306 and heat-dissipating fins 307 are installed on the air boxes 301 set on both sides inside the drying hood 2. The top of the air box 301 is connected to the fan unit 304 through the air cover 302 and the air inlet pipe 303, so as to blow hot air outward at the inlet and outlet of the drying hood 2 at both ends.

[0029] When it is necessary to prevent external dust from entering the drying hood 2 and to prevent sudden temperature rises and falls when the cover plate is moved in and out, the temperature controller 201 is first started to control the heating coil 204 to heat up until the preset temperature is reached. Then, the coated glass cover plate is placed on the conveyor belt 101 and moved into the drying hood 2. At this time, two sets of fans 304 are started to draw external air into the air inlet pipe 303 and into the air box 301 through the air cover 302. Since the air box 301 is equipped with heat-conducting copper pipes 305, and the heat-conducting copper pipes 305 are located in two parts, inside and outside the air box 301, respectively connected to heat dissipation fins 307 and heat-conducting fins 306. Because the heat-conducting fins 306 are close to the heating coil 204, the heating coil... After the temperature rises to 204, the heat-conducting fins 306 also heat up due to heat radiation. The heat is transferred to the heat-dissipating fins 307 through the heat-conducting copper pipe 305. At this time, the flowing air entering the air box 301 undergoes heat exchange with the heat-dissipating fins 307, causing the high-temperature air to slowly blow out from the air outlet 308. The cover plate, which is about to enter the drying hood 2, can be slowly preheated by the hot air flowing above it before entering the drying hood 2 to wait for drying. After the dried cover plate is removed from the drying hood 2, the high-temperature airflow will blow above the cover plate for a period of time to effectively prevent a sudden drop in temperature. This device helps to prevent external dust from entering the drying hood 2 and prevents the ambient temperature from rising or falling suddenly when the cover plate enters or leaves.
