[0002] During the chip manufacturing process, the chip needs to be cleaned. After cleaning, there will be a large amount of liquid on the chip. If it is dried directly with a dryer, it will take a long time to dry the liquid on the chip. The long time is low and the efficiency is low. In addition, when the conveyor belt conveys the chip, the dryer will produce certain gases, which can easily blow the chip crooked, causing the chip to shift and affect the transportation of the chip.

[0003] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0004] In order to solve the above problems, the utility model discloses a drying structure for the sheet, which uses an air knife to blow away the larger liquid particles and residues on the sheet, and then conveys the sheet under the limit of a guide bar, while drying it in an oven, effectively improving the drying efficiency of the sheet.

The sheet is transported by a conveyor belt, and the guide strips limit the sheet and prevent it from deviating.

[0007] Preferably, the oven is rectangular as a whole, the length direction of the oven is perpendicular to the feeding direction of the box body, and both ends of the bottom plate of the oven are fixed to the inner side wall of the box body in the length direction through a fixing plate.

[0010] By adopting the above technical solution, the hot air in the oven is discharged outward through the air outlets, and the air outlets are all over the bottom plate, so that all the hot air in the oven can be released to the material sheets to the greatest extent to dry the material sheets. The width of the bottom plate of the oven can completely cover the longitudinal width of the transmission belt, that is, all the material sheets on the conveyor belt can be dried.

[0011] Preferably, the cover body and the bottom plate fit together, a cavity is provided in the cover body for storing hot air, an air inlet is provided on the cover body, and the air inlet is connected to the hot air duct through an air inlet duct.

[0028] like Figure 1-4 As shown, the drying structure of the sheet includes an air knife 2, an oven 3, a hot air duct 5 and a conveyor belt 6 located in a box body 1. The oven 3 is located in the box body 1 in sequence. The oven 3 includes a cover 3-1 and a bottom plate 3-2. The bottom plate 3-2 is provided with an air outlet 3-21. The air knife 26 is located at the sheet inlet on one side of the oven 3. The tail of the box body 1 is a discharge plate 8, and a through groove 8-1 is provided on the discharge plate 8. A guide bar is provided above the conveyor belt 6. When the sheet is cleaned through the previous process, it enters the drying structure. The sheet is first blown strongly by the air knife 2 to blow away impurities and larger water droplets. Then, the sheet is dried by the oven 3 and conveyed by the conveyor belt 6. The guide bar limits the sheet and prevents it from deviating.

[0029] The oven 3 is rectangular as a whole, and the length direction of the oven 3 is perpendicular to the feeding direction of the box body 1. The two ends of the bottom plate of the oven 1 are fixed to the inner side wall of the box body 1 in the length direction through the fixing plate 9. The oven 3 can dry the sheets conveyed by each conveyor belt 6 in the length direction, thereby improving the drying efficiency of the passing sheets.

[0030] The oven 3 is located on both sides of the hot air duct 5, and the air outlets 3-21 are arranged adjacent to each other on the bottom plate 3-2. The bottom plate 3-2 is covered with air outlets 3-21, which are through holes penetrating the bottom plate 3-2. The width of the bottom plate 3-2 is greater than the combined width of the transmission belts. The hot air in the oven 3 is discharged outward through the air outlets. The air outlets 3-21 are distributed all over the bottom plate 3-2, so that all the hot air in the oven 3 can be released to the sheet to the greatest extent to dry the sheet. The width of the bottom plate of the oven 3 can completely cover the combined longitudinal width of the transmission belts, that is, all the sheets on the conveyor belt can be dried.

[0031] The cover body 3-1 and the bottom plate 3-2 fit together, and a cavity is provided inside the cover body 3-1 for storing hot air. An air inlet is provided on the cover body 3-1, and the air inlet is connected to the hot air duct 5 through the air inlet duct 4. The hot air is stored in the cavity, so that when the air outlet discharges air, the hot air stored in the cavity can be transferred and released in time without causing time delay.

[0032] The hot air duct 5 is connected to an external hot air source. The hot air duct 5 is columnar and parallel to the oven 3. The hot air duct 5 draws hot air from the outside, and then stores the hot air source in the oven 3 through an air inlet duct 4 connected to the hot air duct 5 and the oven 3, so as to dry the sheet material and improve the drying efficiency of the sheet material.

[0033] The conveyor belt 6 is located in the feeding direction of the box body 1 in sequence, the guide bar 7 is located above the conveyor belt 6 and passes through the box body 1, close to the conveyor belt 6, the conveying direction of the guide bar 7 and the conveyor bar 6 is consistent, the guide bar 7 is two parallel vertical plates perpendicular to the conveyor belt 6, the guide bar 7 and the size of the sheet are matched, the bottom of the sheet on the conveyor belt 6 is transported by the conveyor belt 6, and the upper two sides are located in the guide bar 7. When the conveyor belt 6 is transporting the sheet, the guide bar 7 always limits the sheet, which can effectively prevent the sheet from shifting during the transmission process, until the sheet is transmitted to the end of the conveyor belt 6 and goes out of the through slot 8-1 to the next process.

[0034] The length direction of the through slot 8-1 is perpendicular to the feeding direction of the box 1, and the bottom of the through slot 8-1 is flush with the conveyor belt 6. The through slot 8-1 is set on the discharge plate 8 to transport the chips out of the box 1. If the material sheet falls, it can also fall into the box 1 in the discharge plate 8, which is convenient for the later staff to collect.

[0035] The sheet is transported on the conveyor belt 6, and the guide strip 7 serves as a limit for the sheet. The sheet is first blown forcefully by the wind knife to blow off the residue and larger water droplets on the sheet, and then the conveyor belt 6 transports it to the bottom of the oven 3. The air outlet 3-21 of the oven 3 dries the sheet, and the conveyor belt 6 transports the sheet from the through slot 8-1 of the discharge plate 8 to the next process.
