[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0028] Combination Figures 1 to 5As shown, the sheet gluing and continuous drying device provided by the embodiment of the utility model includes a drying box 1, a gluing mechanism 2, which is installed on the drying box 1, a tensioning mechanism 4, which is installed on the side of the inner wall of the drying box 1 away from the feed port, a drying mechanism 5, which is installed inside the drying box 1, a cooling box 6, a fan 7, which is installed at the lower end of the inner wall of the cooling box 6, and is used to dissipate heat for the dried sheet, a first refrigeration roller 8, a second refrigeration roller 9 and a third refrigeration roller 10, which are installed inside the cooling box 6, and the sheet passes through the first refrigeration roller 8, the second refrigeration roller 9 and the third refrigeration roller 10 in the cooling box 6 in sequence, and the temperatures of the first refrigeration roller 8, the second refrigeration roller 9 and the third refrigeration roller 10 are reduced in sequence.

[0029] Therefore, the gluing mechanism is used to evenly apply glue to the sheet, the tensioning mechanism is used to adjust the tension of the sheet to make it flat, the drying mechanism is used to evenly dry the sheet in all directions, and the fan, the first refrigeration roller, the second refrigeration roller and the third refrigeration roller are used to gently and stably cool the dried sheet, thus solving the problem of sheet shrinkage and improving the quality and stability of the sheet.

[0030] The fan 7 is located below the first refrigeration roller 8 , the second refrigeration roller 9 and the third refrigeration roller 10 .

[0031] In some embodiments, Figure 1 and Figure 3 As shown, the gluing mechanism 2 includes a glue storage box 21, a heating rod 22, a ring-shaped heating pad 23 and a glue application roller 24. The glue storage box 21 is fixedly connected to the upper end of the drying box 1 near the feed port, and the lower end of the glue storage box 21 extends into the drying box 1. The heating rod 22 is located at the upper end of the inner cavity of the drying box 1, and the lower end of the glue storage box 21 is fixedly connected to an output pipe. The front and rear side walls of the inner cavity of the drying box 1 are rotatably equipped with a glue application roller 24 near the glue storage box 21. The top surface of the glue application roller 24 abuts against the lower end of the output pipe, and the bottom surface of the glue application roller 24 fits the surface of the sheet.

[0032] Therefore, when the device is to be used, the heating rod 22 and the annular heating pad 23 are started to prevent the glue in the glue storage box 21 from condensing. When the sheet enters the device, the glue roller 24 is driven to rotate so that the glue roller 24 glues the sheet.

[0033] In some embodiments, Figure 1 and Figure 5 As shown, the tensioning mechanism 4 includes a cylinder assembly 41 and a tensioning roller 42. The cylinder assembly 41 is installed on a side of the inner wall of the drying box 1 away from the feed port, and the tensioning roller 42 is rotatably connected to the output end of the cylinder assembly.

[0034] Therefore, when the sheet moves in the device, the cylinder assembly 41 is started to drive the tension roller 42 to move, adjust the tension of the sheet, and make the sheet flat in the device.

[0035] In some embodiments, Figure 1 and Figure 4 As shown, the drying mechanism 5 includes a hot air blower 51, a surrounding air electric fan 52 and an electric heating network 53. There are two hot air blowers 51, which are respectively installed on the inner walls of the upper and lower ends of the drying box 1. The electric heating network 53 is installed inside the drying box 1. The surrounding air electric fan 52 penetrates the electric heating network 53. The surrounding air electric fan 52 is installed in the middle of the drying box 1 horizontally along the width of the sheet.

[0036] Therefore, when the sheet enters the device, the hot air blower 51, the surrounding air electric fan 52 and the electric heating network 53 are started to evenly dry the sheet on both sides in multiple directions.

[0037] In some embodiments, Figure 1 and Figure 2 As shown, it also includes an exhaust mechanism 3, which includes an exhaust fan 31 and a gas purification layer 32. The input end of the exhaust fan 31 is fixedly connected to the upper end of the drying box 1, and the gas purification layer 32 is installed at the connection between the exhaust fan 31 and the drying box 1.

[0038] Therefore, when the device is working, the exhaust fan 31 is turned on to circulate the gas in the drying box 1. When the sheets are dried, gas with a pungent odor will be generated. The gas purification layer 32 can remove the gas with a pungent odor in the body to prevent the discharged gas from polluting the environment.

[0039] The gas purification layer 32 contains activated carbon particles.

[0040] The following is combined with Figure 1-5 Describe a specific embodiment of the utility model:

[0041] like Figure 1-Figure 5 As shown, it includes a drying box 1, a gluing mechanism 2, which is installed on the drying box 1, a tensioning mechanism 4, which is installed on the side of the inner wall of the drying box 1 parallel to the feed port, a drying mechanism 5, which is installed inside the drying box 1, a cooling box 6, a fan 7, which is installed at the lower end of the inner wall of the cooling box 6, and is used to dissipate heat for the dried sheet, a first refrigeration roller 8, a second refrigeration roller 9 and a third refrigeration roller 10, which are installed inside the cooling box 6, and the sheet passes through the first refrigeration roller 8, the second refrigeration roller 9 and the third refrigeration roller 10 in the cooling box 6 in sequence, and the temperatures of the first refrigeration roller 8, the second refrigeration roller 9 and the third refrigeration roller 10 are reduced in sequence, and also includes an exhaust mechanism 3, the exhaust mechanism 3 includes an exhaust fan 31 and a gas purification layer 32, the exhaust fan 31 is fixedly connected to the upper end of the drying box 1, and the gas purification layer 32 is installed at the connection between the exhaust fan 31 and the drying box 1.

[0042] In actual use, when the device is about to be used, the heating rod 22 and the annular heating pad 23 are started to prevent the glue in the glue storage box 21 from condensing. When the sheet enters the device, the glue roller 24 is driven to rotate so that the glue roller 24 glues the sheet. When the sheet enters the device, the hot air blower 51, the surrounding wind-type electric fan 52 and the electric heating network 53 are started to dry the sheet evenly on both sides and in multiple directions. The cylinder assembly 41 is started to drive the tensioning roller 42 to move, adjust the tension of the sheet, and make the sheet flat in the device. The exhaust fan 31 allows the gas in the drying box 1 to circulate. When the sheet is dried, gas with a pungent odor will be generated. The gas purification layer 32 can remove the gas with the pungent odor in the body to prevent the discharged gas from polluting the environment. When the sheet is dried, it enters the cooling box 6, and the fan is turned on to perform preliminary heat dissipation on the sheet. Then, the first refrigeration roller, the second refrigeration roller and the third refrigeration roller, whose temperatures decrease successively, are used to cool the dried sheet smoothly and stably, thereby solving the problem of sheet shrinkage and improving the quality and stability of the sheet.
