[0056] Please refer to Figure 1 and Figure 2 , the present utility model provides an oven device for coil packaging. This oven device can be part of a coil packaging line, and of course, it can also be used independently in other fields. Specifically, the oven device includes a machine platform 1, an oven body 8, a mounting frame 2, and an air-cooling assembly 3. Among them, the oven body 8 is arranged on the machine platform 1. The machine platform 1 may include two cabinet structures that are vertically and oppositely arranged. The mounting frame 2 is arranged on the machine platform 1, and the mounting frame 2 is located in front of the outlet end of the oven body 8. After the PVC coil wrapped with plastic packaging is sent out from the outlet end of the oven body 8, the PVC coil passes under the mounting frame 2. The air-cooling assembly 3 is arranged on the mounting frame 2, and when it works, it can blow cold air downward, so as to air-cool and cool the plastic packaging on the surface of the PVC coil passing under the mounting frame 2, that is, the heat on the surface of the plastic packaging is taken away by the cold air, so that the temperature on the surface of the plastic packaging will not be too high, and the risk of scalding can be reduced when production personnel carry the packaged PVC coil.

[0057] As Figure 1 and Figure 2 shown, in a preferred embodiment of the present utility model, it includes a fan 301 and a cooling coil 302. A plurality of the fans 301 can be arranged side by side, and the fans 301 are all mounted on the mounting frame 2. The cooling coil 302 is located below the fan 301 and is connected to the mounting frame 2, and a coolant circulates in the cooling coil 302. By circulating the coolant in the cooling coil 302, the surface of the cooling coil 302 can be maintained at a relatively low temperature. When the air blown downward by the fan 301 passes through the cooling coil 302, the temperature of the cold air can be further reduced, so as to improve the effect of air-cooling and cooling.

[0058] The coolant can be low-temperature cooling water or heat-conducting oil. When the coolant is cooling water, the cooling coil 302 can be connected to a cooling water tower through a cooling water delivery pipeline, thereby ensuring a sufficient supply of cooling water.

[0059] It can be understood that the cooling water tower can be used in conjunction with the heat exchanger to ensure that the coolant can be cooled down.

[0060] As Figure 1 and Figure 2 shown, in a preferred embodiment of the present invention, the cooling coil 302 is in an S shape. When the air outlet area of the fan 301 increases, it can ensure that more air contacts the cooling coil 302, and the air-cooling effect is better. In addition, both the coolant inlet and the coolant outlet of the cooling coil 302 are located on the same side of the mounting frame 2, which is convenient for laying out the coolant delivery pipes and does not complicate the layout of the coolant delivery pipes.

[0061] As Figure 1 、 Figure 4 、and Figure 5 shown, in a preferred embodiment of the present invention, the oven device further includes a driving sprocket 4, a driven sprocket 5, a transmission chain 6, a support rod 7, and a driving mechanism.

[0062] Among them, there are two driving sprockets 4 in total. The two driving sprockets 4 are arranged in parallel inside the machine table 1, and the two driving sprockets 4 are connected by a first connecting shaft; the number of driven sprockets 5 is the same as that of the driving sprockets 4. Specifically, the two driven sprockets 5 are arranged in parallel inside the machine table 1, and the two driven sprockets 5 are connected by a second connecting shaft. The driven sprocket 5 and the driving sprocket 4 are respectively located on both sides of the oven body 8.

[0063] And there are two groups of transmission chains 6 arranged in parallel. Each group of transmission chains 6 is simultaneously wound around the driving sprocket 4 and the driven sprocket 5. The driving mechanism can be a motor, and its output shaft is in transmission connection with one of the driving sprockets 4, so as to be able to drive the driving sprocket 4 to rotate, and further realize the movement of the transmission chain 6. A plurality of support rods 7 are provided, and both ends of each support rod 7 are arranged on the two transmission chains 6. The support rod 7 can be a high-temperature-resistant metal rod body, which is used to support the packaged PVC coil, and together with the moving transmission chain 6, enables the packaged PVC coil to travel inside the oven body 8.

[0064] Compared with the conveying structures of other structures, the conveying structure composed of the transmission chain 6, the support rod 7, etc. provided in the above embodiment will not have safety hazards such as fire during use.

[0065] As Figure 1 、 Figure 2 、and Figure 7As shown, in a preferred embodiment of the present utility model, the oven body 8 includes a support wall 81, a top plate 82, a hot air blower 83, and a heating assembly 84. Among them, there are two support walls 81, which are vertically arranged on the machine table 1, and a first vertical air duct 811 is provided inside the support wall 81, and an air inlet and outlet 812 communicating with the first vertical air duct 811 is provided on the inner side of the support wall 81. The top plate 82 is arranged on the upper parts of the two support walls 81, and a first horizontal air duct 821 communicating with the first vertical air duct 811 is provided inside the top plate 82. The hot air blower 83 is arranged on the top plate 82, the air inlet of the hot air blower 83 is located below the top plate 82, and the air outlet of the hot air blower 83 is located in the first horizontal air duct 821; and the heating assembly 84 may include multiple heating tubes, and the heating assembly 84 is arranged in the first horizontal air duct 821.

[0066] When the hot air blower 83 works, the hot air blower 83 sucks the air in the oven body 8 into the first horizontal air duct 821, and the heating assembly 84 may be arranged facing the air outlet of the hot air blower 83. Therefore, when the air is discharged from the air outlet of the hot air blower 83, the air can be heated and raised in temperature by the heating assembly 84. Under the action of wind pressure, the heated air enters the first vertical air duct 811 and enters the oven body 8 through the aforementioned air inlet and outlet 812, thereby realizing the heat circulation of the air in the oven, and the plastic packaging on the surface of the PVC coil can be heated and shrunk in the oven.

[0067] It can be understood that multiple hot air blowers 83 may be provided, and the air outlets of the hot air blowers 83 may face Figure 7 the right side, or may face Figure 7 the left side in the middle. Correspondingly, the heating assembly 84 may also be arranged on both the left and right sides of the hot air blower 83 at the same time, so that hot air will be delivered to the oven body 8 on the inner sides of the two support walls 81, making the plastic packaging evenly heated.

[0068] Of course, when the air outlets of all the hot air blowers 83 face the same direction, the air inlet and outlet 812 on the inner side of one of the support walls 81 mainly functions as an air inlet, so that part of the air in the oven body 8 can first enter the first vertical air duct 811 and then be delivered to the first horizontal air duct 821.

[0069] Such as Figures 5 to 7As shown, in a preferred embodiment of the present utility model, the oven body 8 further includes a bottom plate 85; both ends of the bottom plate 85 are passed through the machine table 1 and are located between the upper side and the lower side of the drive chain 6; a second vertical air duct 101 communicating with the first vertical air duct 811 is provided on the machine table 1; a second horizontal air duct 851 is provided on the bottom plate 85, and the second horizontal air duct 851 communicates with the second vertical air duct 101. Thus, the air heated by the heating component 84 can enter the interior of the bottom plate 85 (i.e., the second horizontal air duct 851) through the second vertical air duct 101; and air outlet holes 852 communicating with the second horizontal air duct 851 are provided on the inner side of the bottom plate 85, so that the hot air can be blown upward from the air outlet holes 852 to the bottom of the PVC coil, ensuring that all sides of the plastic packaging can be evenly heated and the packaging effect of the PVC coil is good.

[0070] When the oven body 8 is used for a long time, debris will fall downward from the inner wall of the top plate 82. The setting of the bottom plate 85 makes the debris only fall on the bottom plate 85. Therefore, in order to regularly clean the debris on the bottom plate 85, in a preferred embodiment of the present utility model, the machine table 1 is provided with an opening 102 that cooperates with the bottom plate 85. The length direction of the opening 102 is the same as the length direction of the machine table 1, so that the bottom plate 85 can be movably passed through the opening 102 and thus can be pulled out to the outside of the machine table 1, facilitating the production personnel to clean the debris on the bottom plate 85.

[0071] In addition, support columns for supporting the bottom plate 85 are provided at the bottom of the bottom plate 85, and both ends of the support columns are connected to the inner side of the machine table 1. The setting of the support columns ensures that the bottom plate 85 can be smoothly pulled out of the machine table 1 and also ensures that the bottom plate 85 can be pushed between the upper and lower sides of the drive chain 6.

[0072] Since the opening 102 is in shape cooperation with the bottom plate 85, the opening 102 can be used to guide the movement of the bottom plate 85. When the bottom plate 85 can be pushed between the upper and lower sides of the drive chain 6 and cannot be pushed forward any further, it can be ensured that the second vertical air duct 101 and the second horizontal air duct 851 are in communication.

[0073] Of course, in order to facilitate pushing and pulling the bottom plate 85, one side of the bottom plate 85 is always located outside the machine table 1, and a groove structure (not shown in the drawings) convenient for hand holding can be provided on this side.

[0074] As Figure 6 shown, in a preferred embodiment of the present utility model, the opening 102 is rectangular, and its inner width value in the vertical direction is greater than the thickness value of the bottom plate 85, so that when the bottom plate 85 is pulled out of the machine table 1, the debris on the bottom plate 85 can also be removed from the machine table 1 together with the bottom plate 85, facilitating the subsequent production personnel to clean the debris on the bottom plate 85.

[0075] In addition, a baffle 86 for covering the opening 102 is provided on the upper part of the bottom plate 85. When the bottom plate 85 is between the upper and lower sides of the drive chain 6, the bottom plate 85 can block the opening 102, so that the heat in the oven body 8 will not leak to the outside of the oven body 8.

[0076] As Figure 1 and Figure 3 shown, in a preferred embodiment of the present utility model, heat insulation curtain assemblies are provided at both the inlet end and the outlet end of the oven body 8. The heat insulation assembly 9 can block the heat from being transferred into the oven body 8, thereby reducing heat damage and lowering the energy consumption of the oven body 8.

[0077] As Figure 1 and Figure 3 shown, in a preferred embodiment of the present utility model, the heat insulation curtain assembly includes a mounting plate 91 and a heat insulation curtain 92. The mounting plate 91 is adsorbed on the side of the oven body 8 by a magnet 93; the heat insulation curtain 92 is detachably arranged on the mounting plate 91.

[0078] Since the mounting plate 91 can be adsorbed on the oven body 8 by the magnet 93, the height of the mounting plate 91 can be adjusted, so that the height of the lower end of the mounting curtain can also be adjusted, enabling PVC coils with different diameters to pass under the heat insulation curtain 92.

[0079] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
