[0039] The following is combined with Figure 1-5 This application is described in further detail.
[0040] The embodiment of the present application discloses a hollow plate production line oven device.
[0041] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0042] Reference Figure 1 and Figure 2 A hollow board production line oven device includes a box body 1 and a drying mechanism 2. The box body 1 is provided with a uniform wind component 11, and the drying mechanism 2 is provided on the box body 1. The drying mechanism 2 is used to produce hot air and can convey the hot air to the uniform wind component 11, and the uniform wind component 11 can uniformly convey the hot air into the box body 1 to uniformly dry the hollow board in the box body 1.
[0043] Reference Figure 2 The box body 1 is provided with a feed port 12 and a discharge port 13 facing each other, so that the hollow board can enter the box body 1 from the feed port 12, and the hollow board can leave the box body 1 from the discharge port 13. In this embodiment, a feed roller 14 is installed at one end of the box body 1 close to the feed port 12, and a discharge roller 15 is installed at one end of the box body 1 close to the discharge port 13, and both the feed roller 14 and the discharge roller 15 are used to support the hollow board to reduce the possibility of deformation of the hollow board due to hanging in the air.
[0044] Reference Figure 1 and Figure 2 The drying mechanism 2 includes a hot air component 21, a conveying roller group 22 and a circulation pipe group 23. In this embodiment, the hot air component 21 is a hot air blower, which is installed on the box body 1 and can heat the external air into hot air and convey the hot air into the box body 1.
[0045] Reference Figure 2 and Figure 3 The wind uniformity assembly 11 includes a wind uniformity sleeve 111 and a connector 112. The wind uniformity sleeve 111 is connected to the inner wall of the box body 1 through the connector 112, and the wind uniformity sleeve 111 is spaced apart from the inner wall of the box body 1, so that a closed wind cavity 113 is formed between the wind uniformity sleeve 111 and the inner wall of the box body 1. In this embodiment, the connector 112 is a bolt. In other embodiments, the connector 112 can also be configured as a bracket.
[0046] Reference Figure 2 and Figure 4 A plurality of air outlets 1111 are evenly arranged on the air uniforming sleeve 111 , and the air outlets 1111 are connected to the wind cavity 113 , and the plurality of air outlets 1111 are divided into two groups, one group of air outlets 1111 is located on the upper top surface of the air uniforming sleeve 111 , and the other group of air outlets 1111 is located on the lower top surface of the air uniforming sleeve 111 .
[0047] The hot air blower is connected to the air cavity 113, so that the hot air produced in the hot air blower can be transported to the air cavity 113, and the hot air can flow out from different air outlets 1111 when flowing in the air cavity 113, so that the hot air can blow on the upper and lower sides of the hollow board at the same time, so as to improve the heating uniformity of the hollow board, thereby facilitating the drying of the hollow board.
[0048] In this embodiment, the air outlet 1111 is a strip structure, which avoids the concentration of hot air to a certain extent, thereby helping to reduce the possibility of hot air centrally heating a local area of the hollow plate, and further improving the heating uniformity of the hollow plate.
[0049] Reference Figure 2 The conveying roller group 22 includes a plurality of conveying rollers 221 rotatably connected to the box body 1 , the plurality of conveying rollers 221 are parallel to each other, and the plurality of conveying rollers 221 are grouped in pairs, and the two conveying rollers 221 in the same group are distributed at intervals in the vertical direction.
[0050] When the hollow board enters the box body 1 from the feed port 12, the hollow board can enter between the two conveying rollers 221, so that the two conveying rollers 221 can limit the hollow board together to reduce the possibility of displacement or vibration of the hollow board when it is blown by hot air, so that the hollow board is not easily deformed by the hot air. And the multiple conveying rollers 221 cooperate with each other to convey the hollow board from the feed port 12 to the discharge port 13, thereby facilitating the conveyance of the hollow board on the one hand, and preventing sliding friction between the hollow board and the conveying rollers 221 on the other hand.
[0051] Reference Figure 2 and Figure 5 The conveying roller 221 is made of heat-conducting material, and a through groove 2211 is opened in the conveying roller 221 along its own axial direction. A plurality of air inlet grooves 2212 are opened on the circumferential outer wall of the conveying roller 221, and the air inlet grooves 2212 are connected with the through grooves 2211, so that the hot air will enter the through grooves 2211 from the air inlet grooves 2212 after blowing through the hollow plate, so as to utilize the hot air to quickly increase the temperature of the conveying roller 221, so that the temperature of the conveying roller 221 is consistent with the temperature of the hot air, and then the conveying roller 221 can heat the hollow plate, so as to reduce the possibility that the conveying roller 221 blocks the hot air and causes uneven heating of the hollow plate.
[0052] In other embodiments, in order to further improve the uniformity of heating of the hollow board, before the hollow board enters the box 1, the conveying roller 221 can be heated by hot air. After the temperature of the conveying roller 221 is consistent with the temperature of the hot air, the hollow board is conveyed to the box 1 for drying, thereby avoiding the temperature of the conveying roller 221 being lower than the temperature of the hot air, which causes uneven heating of the hollow board.
[0053] It should be noted that, in the embodiment of the present application, the specific method used to drive the conveying roller 221 to rotate and the specific material definition of the conveying roller 221 are conventional technical means for those skilled in the art. Therefore, no further elaboration is made in the embodiment of the present application.
[0054] Reference Figure 1 The circulation pipe group 23 includes a first pipe 231 and a second pipe 232. The first pipe 231 is connected to the air inlet of the hot air blower, so that when the hot air blower is working, the external air will enter the hot air blower through the first pipe 231. In this embodiment, the diameter of the middle part of the first pipe 231 is smaller than the diameter of the two ends, so that the flow rate of the gas will be accelerated when passing through the middle part of the first pipe 231, so as to form a negative pressure in the middle part of the first pipe 231.
[0055] Reference Figure 2 and Figure 5The number of the second pipes 232 is equal to the number of the conveying rollers 221 and is arranged one by one. One end of the second pipe 232 is connected to the through groove 2211, and the other end of the second pipe 232 is connected to the middle of the first pipe 231, so that the gas in the box body 1 can pass through the air inlet groove 2212, the through groove 2211 and the second pipe 232 in sequence and enter the first pipe 231.
[0056] When the hot air blower is working and there is hot air in the box body 1, due to the negative pressure formed in the middle of the first pipe 231, the gas in the second pipe 232 can be sucked into the first pipe 231, so that the gas in the through groove 2211 flows into the first pipe 231 through the second pipe 232, thereby facilitating the introduction of the hot air in the box body 1 into the first pipe 231, so that the hot air is mixed with the newly added air in the first pipe 231, thereby increasing the temperature of the gas entering the hot air blower, and then facilitating the hot air blower to quickly heat the gas to realize the recycling of thermal energy, thereby improving the energy utilization rate to a certain extent.
[0057] Reference Figure 2 A filter 2311 is installed between the first pipe 231 and the hot air blower. The filter 2311 is used to filter impurities such as dust from the outside, so that impurities are not easy to enter the hot air blower through the first pipe 231, thereby facilitating the hot air blower to produce clean hot air. In other embodiments, the filter 2311 can also be installed at one end of the first pipe 231 away from the hot air blower.
[0058] The implementation principle of a hollow board production line oven device in the embodiment of the present application is as follows: when the hollow board needs to be dried, the hot air blower is first started to convey hot air into the air cavity 113, so that the hot air flows in the air cavity 113 and flows into the box body 1 through different air outlets 1111. Then the hollow board is conveyed from the feed port 12 to the box body 1, and the hollow board is made to enter between the two conveying rollers 221. At this time, the hollow board will be blown by hot air from both the upper and lower directions, so as to facilitate drying of the hollow board. And in this process, the conveying roller 221 will convey the hollow board to the discharge port 13, so as to send the dried hollow board out of the box body 1, thereby completing the drying operation of the hollow board.
[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
