Description

Technical Field

[0001] The utility model relates to a drying furnace structure, in particular to a drying furnace structure used for thermally drying a vehicle body. Background Art

[0002] In the production line of body electroplating / painting, in order to improve productivity and color matching, the body shell with cover parts such as doors and hoods is conveyed through a drying furnace to bake and dry the paint film on the surface of the body. However, the hot air provided by the drying furnace is difficult to circulate inside the body shell, resulting in poor thermal efficiency. In order to make the inside of the body shell have a sufficiently high temperature, the hot air provided by the drying furnace makes the temperature of the outside of the body shell too high, making the temperature inside and outside the body shell uneven, resulting in poor coating quality and / or deformation of the body shell. Therefore, it is necessary to improve the drying furnace to overcome the above problems. Utility Model Content

[0003] The utility model provides a drying furnace structure which can improve the thermal efficiency when thermally drying a vehicle body.

[0004] The utility model provides a drying furnace structure, comprising: a drying furnace main body; a front channel connected to the front end of the drying furnace main body; and a rear channel connected to the rear end of the drying furnace main body. The drying furnace structure is arranged so that a vehicle body passes through the front channel, the drying furnace main body and the rear channel in sequence in a manner of the roof facing downward. In the up and down direction of the drying furnace structure, the front channel and the rear channel are located above the drying furnace main body.

[0005] The utility model provides a drying furnace structure, comprising: a drying furnace main body, wherein the drying furnace structure is arranged so that a vehicle body passes through the drying furnace main body with the roof facing downward, and when the vehicle body passes through the drying furnace main body, the drying furnace structure causes the vehicle body to shake up and down or left and right.

[0006] Based on the above, in the drying furnace structure of the utility model, the car body passes through the drying furnace body in a manner that the roof faces downward, so that the window openings of the car body are located at a relatively lower position. Therefore, after the hot air provided by the drying furnace structure enters the car body, based on the principle that hot air rises, the hot air in the car body will not easily flow to the outside of the car body through the window openings, etc., and the hot air will convect in the car body for a long time. In addition, in one embodiment of the utility model, the positions of the front channel and the rear channel are higher than the position of the drying furnace body. Accordingly, based on the principle that hot air rises, the hot air in the drying furnace body tends to flow to the front channel and the rear channel rather than tending to stagnate, which can increase the fluidity of the hot air and make it easy for the hot air to flow into the car body. In addition, in another embodiment of the utility model, when the car body passes through the drying furnace body, it will shake up and down or shake left and right, which can promote the convection of the hot air and make it easy for the hot air to flow into the car body. Thereby, the drying furnace structure of the utility model can improve the thermal efficiency when the car body is thermally dried.

[0028] Figure 1 It is a schematic diagram of a drying furnace structure according to an embodiment of the present invention, which shows the axial directions X, Y and Z. Figure 2 yes Figure 1 Partial front view of the drying furnace structure. Please refer to Figure 1 and Figure 2 The drying furnace structure 100 of this embodiment is used in a vehicle body electroplating / painting production line to thermally dry the vehicle body shell (i.e., the vehicle body 50 described later) with cover parts such as doors and engine hoods, and to bake the paint film on the surface of the vehicle body.

[0029] The drying furnace structure 100 includes a drying furnace body 110, a front channel 120, and a rear channel 130. The front channel 120 is connected to the front end 110a of the drying furnace body 110 and extends obliquely upward from the front end 110a of the drying furnace body 110, and the rear channel 130 is connected to the rear end 110b of the drying furnace body 110 and extends obliquely upward from the rear end 110b of the drying furnace body 110. Therefore, in the up-down direction (axial direction Z) of the drying furnace structure 100, the front channel 120 and the rear channel 130 are located above the drying furnace body 110. The drying furnace structure 100 is configured so that the vehicle body 50 is as shown in FIG. Figure 1 As shown, the vehicle passes through the front passage 120, the drying furnace body 110 and the rear passage 130 in sequence with the roof 52 facing downward, so that the hot air A (indicated by Figure 2 ) The vehicle body 50 is thermally dried.

[0030] As described above, in the drying furnace structure 100 of the present embodiment, the vehicle body 50 passes through the drying furnace main body 110 in a manner that the roof 52 faces downward, so that the window openings of the vehicle body 50 are located at a relatively lower position. Therefore, after the hot air A provided by the drying furnace structure 100 enters the vehicle body 50, based on the principle that hot air rises, the hot air A in the vehicle body 50 will not easily flow to the outside of the vehicle body 50 through the window openings, etc., and the hot air A will convect in the vehicle body 50 for a long time. In addition, the positions of the front channel 120 and the rear channel 130 are higher than the position of the drying furnace main body 110. Accordingly, based on the principle that hot air rises, the hot air A in the drying furnace main body 110 tends to flow to the front channel 120 and the rear channel 130 rather than tending to stagnate, which can increase the fluidity of the hot air A and make it easy for the hot air A to flow into the interior of the vehicle body 50. Therefore, the drying furnace structure 100 of the present embodiment can improve the thermal efficiency when the vehicle body 50 is thermally dried.

[0031] In detail, the drying furnace structure 100 of the present embodiment further includes a conveying unit 140 and a hot air providing unit 150. The conveying unit 140 may include a conveying belt 142 or other types of conveying devices, which are used to convey the vehicle body 50 through the drying furnace main body 110 in a manner such that the vehicle roof 52 faces downward. Specifically, the conveying surface 142a of the conveying belt 142 faces downward and is used to connect to the bottom of the vehicle body 50 so that the vehicle roof 52 of the vehicle body 50 faces downward. The hot air providing unit 150 is used to provide hot air A into the drying furnace main body 110. The specific configuration and function of the hot air providing unit 150 are known in the art and will not be described in detail herein.

[0032] Figure 3 Schematic diagram of the drying furnace structure of another embodiment of the utility model. Figure 3 In the drying furnace structure 200 of the embodiment shown, the configuration and function mode of the drying furnace body 210, the front channel 220, the rear channel 230, the conveying unit 240 and the hot air providing unit 250 are the same or similar to those of Figure 1 The configuration and function of the drying furnace body 110 , the front channel 120 , the rear channel 130 , the conveying unit 140 and the hot air providing unit 150 of the illustrated embodiment are not described in detail herein.

[0033] Figure 3 The drying furnace structure 200 of the embodiment shown in FIG. Figure 1The main difference of the drying furnace structure 100 of the illustrated embodiment is that, in the drying furnace structure 200, the front channel 220 extends obliquely downward from the front end 210a of the drying furnace body 210, and the rear channel 230 extends obliquely downward from the rear end 210b of the drying furnace body 210. Thus, in the up-down direction (axial direction Z) of the drying furnace structure 200, the front channel 220 and the rear channel 230 are located below the drying furnace body 210 to maintain the hot air in the drying furnace body 210 based on the principle that hot air rises. In addition, in the drying furnace structure 200, the conveying unit 240 of the drying furnace structure 200 is configured to drive the vehicle body 50 to shake up and down. Specifically, the conveying belt 242 included in the conveying unit 240 is as shown in FIG. Figure 3 Accordingly, when the vehicle body 50 moves along the conveyor belt 242 and passes through the drying furnace main body 110, the vehicle body 50 will shake up and down as the conveyor belt 242 is displaced in the up and down directions, thereby promoting the convection of hot air and making it easy for the hot air to flow into the vehicle body 50.

[0034] Figure 4 and Figure 5 They are partial front views of different positions of the drying furnace structure of another embodiment of the utility model. Figure 4 The corresponding position and Figure 5 The corresponding positions are different positions of the drying furnace body 310 in the axial direction Y. Figure 4 and Figure 5 In the drying furnace structure 300 of the embodiment shown, the configuration and function of the drying furnace body 310 and the conveying unit 340 are the same or similar to those of Figure 2 The configuration and function of the drying furnace body 110 and the conveying unit 140 of the illustrated embodiment are not described in detail here.

[0035] Figure 4 and Figure 5 The drying furnace structure 300 of the embodiment shown is Figure 2 The main difference between the drying furnace structure 200 of the embodiment shown is that in the drying furnace structure 300, the conveying unit 340 of the drying furnace structure 300 is configured to drive the vehicle body 50 to shake left and right. Specifically, in the drying furnace structure 300, the conveying belt 342 of the conveying unit 340 is arranged at different positions (such as Figure 4 The position shown is Figure 5 The sections 3421 and 3422 of the vehicle body 50 (shown in the figure) have different inclination angles, so when the vehicle body 50 moves along the conveyor belt 342 and passes through the drying furnace body 310, the vehicle body 50 will shake left and right as the conveyor belt 242 tilts, which can promote the convection of hot air and make it easier for the hot air to flow into the vehicle body 50. In other embodiments, other methods can be used to make the vehicle body 50 shake left and right when passing through the drying furnace body 310, and the utility model is not limited to this.

[0036] In summary, in the drying furnace structure of the utility model, the car body passes through the drying furnace body in a manner that the roof faces downward, so that the window opening of the car body is located at a relatively lower position. Therefore, after the hot air provided by the drying furnace structure enters the car body, based on the principle of hot air rising, the hot air in the car body will not easily flow to the outside of the car body through the window opening, etc., and the hot air will convect in the car body for a long time. In addition, in one embodiment of the utility model, the positions of the front channel and the rear channel are higher than the position of the drying furnace body. Accordingly, based on the principle of hot air rising, the hot air in the drying furnace body tends to flow to the front channel and the rear channel rather than tending to stagnate, so that the fluidity of the hot air can be increased, so that the hot air can easily flow into the interior of the car body. In addition, in another embodiment of the utility model, the car body will shake up and down or shake left and right when passing through the drying furnace body, which can promote the convection of the hot air and make the hot air easy to flow into the interior of the car body. Therefore, the drying furnace structure of the utility model can improve the thermal efficiency of the car body when thermally drying it, and then make the temperature inside and outside the car body shell uniform, so as to ensure the good quality of the car body coating and avoid deformation of the car body shell.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
