Technical Field
[0001] The present application relates to the technical field of cardboard drying, and in particular to a U-shaped lead-insulated cardboard shaping and drying device. Background Art
[0002] At present, a large number of cardboard sheets are required in a transformer box body. Due to its good insulation performance, in the box body lead-out structure as shown in Figure 1 , a U-shaped insulating cardboard 7 needs to be used.
[0003] This cardboard is U-shaped, and its moisture needs to be dried during the production process. In the prior art, generally, two methods of hot air drying or microwave drying are adopted. Microwave drying has the advantage that the cardboard is not easily deformed, but the cost of microwave drying is high and there are many requirements.
[0004] Therefore, in order to save costs, our company adopts the method of hot air drying. However, hot air drying easily causes the U-shaped plate to deform. There is an urgent need to develop a drying device that can ensure that the U-shaped cardboard does not deform. Summary of the Utility Model
[0005] The purpose of the present application is to provide a U-shaped lead-insulated cardboard shaping and drying device to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present application provides a U-shaped lead-insulated cardboard shaping and drying device adopting the following technical solutions:
[0007] A U-shaped lead-insulated cardboard shaping and drying device includes a drying box equipped with a conveyor, and also includes a shaping frame for placing the cardboard. A plurality of card slots are evenly spaced and fixed on the conveyor belt of the conveyor. The shaping frame can be matched and limited in the card slots. The shaping frame includes a base and a pressing block. A plurality of grooves are evenly spaced on the surface of the base. Partition plates are arranged between adjacent grooves. U-shaped blocks are arranged in the grooves. At the position corresponding to the U-shaped blocks at the bottom of the pressing block, there are U-shaped protrusions. A cavity is formed between the U-shaped protrusions and the U-shaped blocks. Extension plates are provided on both sides of the pressing block;
[0008] Guide rods are fixed on the side frames on both sides of the middle of the drying box where the conveyor is located. The guide rods include an inclined ascending section, a raised holding section, and an inclined descending section. The pressing block can be lifted by the extension plates through the guide rods.
[0009] Preferably, a spring is fixed at the bottom end of the U-shaped block, and the bottom of the spring is fixed in the groove.
[0010] By adopting the above technical solution, by providing a spring, when the pressing block disengages from the base, the spring restores its deformation and bounces the U-shaped block upward, so that the cardboard can be separated from the inner surface of the U-shaped block. At this time, the volatilization of water vapor can be accelerated, thereby improving the drying efficiency.
[0011] A telescopic sleeve for guiding the spring is provided inside the spring.
[0012] Preferably, in order to facilitate the loading and unloading of workers, handles are fixed on both sides of the base.
[0013] The conveyor belt is a chain conveyor belt, and a heat conduction plate is provided at the bottom of the card slot.
[0014] Preferably, in order to improve the heat transfer efficiency, a plurality of heat conduction fins are uniformly fixed on the top surface of the pressing block.
[0015] In summary, the present application includes at least one of the following beneficial technical effects: The U-shaped lead insulating cardboard shaping and drying device is provided with a shaping frame and a guide rod. The shaping frame can transfer the heat in the drying box to the cardboard, heat the cardboard to evaporate its moisture, and the heating is relatively uniform. Then, through the contact between the extension plates on both sides of the pressing block and the guide rod, the pressing block is lifted, increasing the contact area between the cardboard and the hot air, so that it can be quickly dried. After the pressing block disengages from the guide rod, it presses on the cardboard again until it exits the drying box, which can shape the dried U-shaped cardboard, and the dried U-shaped cardboard will not deform, and the shaping effect is good.

Detailed Embodiments
[0021] The following is combined with the attached Figures 2 - 4A further detailed description of the present application is provided.
[0022] An embodiment of the present application discloses a U-shaped lead insulating cardboard shaping and drying device. Referring to Figures 2 - 4 , it includes a drying box 2 equipped with a conveyor 1, and also includes a shaping rack 3 for placing cardboard. Card slots 11 are evenly spaced and fixed on the conveyor belt of the conveyor 1. The shaping rack 3 can be matched and limited within the card slots 11. The shaping rack 3 includes a base 31 and a pressing block 32. A plurality of grooves 311 are evenly spaced on the surface of the base 31. Partition plates are arranged between adjacent grooves 311. A U-shaped block 312 is arranged in the groove 311. At the position corresponding to the U-shaped block 312 at the bottom of the pressing block 32, there is a U-shaped convex block 321. A cavity is formed between the U-shaped convex block 321 and the U-shaped block 312. Both sides of the pressing block 32 have extension plates;
[0023] Guide rods 4 are fixed on the side frames on both sides of the middle part of the drying box 2 where the conveyor 1 is located. The guide rods 4 include an inclined ascending section 41, a raised holding section 42, and an inclined descending section 43. The pressing block 32 can be lifted by the guide rods 4 through the extension plates.
[0024] Referring to Figure 4 , a spring 5 is fixed at the bottom end of the U-shaped block 312. The bottom of the spring 5 is fixed in the groove 311. A telescopic sleeve for guiding the spring 5 is arranged inside the spring 5.
[0025] By setting the spring 5, when the pressing block 32 is separated from the base 31, the spring 5 restores its deformation and bounces the U-shaped block 312 upwards, so that the cardboard can be separated from the inner surface of the U-shaped block 312. At this time, the volatilization of water vapor can be accelerated, thereby improving the drying efficiency.
[0026] To facilitate the loading and unloading of workers, handles (not shown in the figure) are fixed on both sides of the base 31.
[0027] Referring to Figure 4 , the conveyor belt is a chain conveyor belt. A heat conducting plate is provided at the bottom of the card slot 11. A number of heat conducting fins 6 are evenly fixed on the top surface of the pressing block 32. The arrangement of the heat conducting plate and the heat conducting fins 6 can quickly transfer heat to the base 31 and the pressing block 32, thereby heating the cardboard.
[0028] The implementation principle of a U-shaped lead insulating cardboard shaping and drying device according to an embodiment of the present application is as follows:
[0029] The staff first place several U-shaped cardboard sheets into the U-shaped block 312, and then place the pressing block 32 correspondingly on the base 31. The U-shaped convex block 321 and the U-shaped block 312 shape the cardboard in the cavity. After that, the staff move the shaping rack 3 as a whole into the card slot 11 in the conveyor 1. The shaping rack 3 enters the drying box 2 together with the conveyor 1. The hot air in the drying box 2 blows on the shaping rack 3, and the shaping rack 3 transfers the heat to the cardboard, so that the cardboard can be heated. During the operation of the shaping rack 3, the extension plates on both sides of the pressing block 32 contact the guide rod 4, and after continuing to operate, the pressing block 32 is lifted up, increasing the contact area between the cardboard and the hot air, so that it can be quickly dried. After the pressing block 32 disengages from the guide rod 4, it presses on the cardboard again until it exits the drying box 2, which can shape the dried U-shaped cardboard and prevent deformation.
[0030] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
