[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a surface drying device for printing and packaging, including a bracket 1 and an adjusting bracket 2. The bracket 1 is rotatably mounted with a plurality of first rollers 101 through a bearing seat, a conveyor belt 102 is mounted on the first roller 101, an adjusting screw 106 is rotatably mounted on the bracket 1, a threaded sleeve 205 is embedded in the adjusting bracket 2, the threaded sleeve 205 is threadedly matched with the adjusting screw 106, a plurality of second rollers 201 are rotatably mounted on the adjusting bracket 2, pressing belts 202 are symmetrically mounted on the second roller 201, a plurality of pressing pieces 3 are equidistantly fixed on the pressing belt 202, and a drying fan 4 is fixedly connected to the adjusting bracket 2 through a supporting arm.

[0022] In this embodiment, a conveyor belt is formed by the support 1, the first roller 101, and the conveyor belt 102. The package is placed on the conveyor belt 102, and the conveyor belt 102 is driven to rotate by a power device to transport the package. At the same time, the second roller 201 is driven to rotate by a linkage mechanism. The rotation of the second roller 201 drives the pressing belt 202 to rotate. The rotation of the pressing belt 202 drives the pressing member 3 to rotate synchronously. When the package moves between the adjustment frame 2 and the support 1, the pressing member 3 presses the corner of the package. The drying fan 4 is provided inside A heating wire is provided, which is not shown in the figure for the prior art. Then, the drying fan 4 can be started to blow out warm air to dry the hard brush ink on the packaging surface. Since the corners of the packaging are pressed by the pressing piece 3, the problem of the packaging being blown away can be effectively avoided. At the same time, the threaded sleeve 205 is threadedly matched with the adjusting screw 106. Rotating the adjusting screw 106 can drive the adjusting frame 2 to move. The movement of the adjusting frame 2 will drive the pressing piece 3 to move, thereby adjusting the distance between the pressing piece 3 and the conveyor belt 102, which is used to adapt to the pressing and fixing of packages of different thicknesses.

[0023] In order to achieve the purpose of synchronous rotation of the pressing belt 202 and the conveyor belt 102, the present device adopts the following technical solution: a driving motor 103 is fixedly connected to one side of the bracket 1, and the output end of the driving motor 103 is fixedly connected to a first roller shaft 101 in front, a first belt pulley 104 is fixedly connected to one end of the first roller shaft 101 in the rear, and a second belt pulley 206 is fixedly connected to one end of the second roller shaft 201 in the rear, and the second belt pulley 206 is linked with the first belt pulley 104 through the connecting belt 6. A limit vertical rod 105 is fixedly connected to the front and rear of the adjusting screw 106, and a limit through hole 204 is provided in the adjusting frame 2 and at the front and rear of the threaded sleeve 205. The limit through hole 204 is slidably matched with the limit vertical rod 105. A dovetail groove 5 is provided on one side of the bracket 1, and a dovetail slider 502 is slidably installed in the dovetail groove 5. A return spring 501 is fixedly connected to the dovetail groove 5, and the other end of the return spring 501 is fixedly connected to the dovetail slider 502. A tensioning wheel 503 is rotatably installed on the dovetail slider 502 through an axis.

[0024] By starting the driving motor 103, the first roller 101 can be driven to rotate. The rotation of one first roller 101 can drive the conveyor belt 102 to rotate, thereby synchronously driving the other first rollers 101 to rotate. The rotation of the first roller 101 can drive the first belt pulley 104 to rotate. The first belt pulley 104 is linked with the second belt pulley 206 through the connecting belt 6. Therefore, the rotation of the first belt pulley 104 can drive the second belt pulley 206 to rotate. The rotation of the second belt pulley 206 can drive the second roller 201 to rotate, so that the pressing belt 202 can rotate synchronously with the conveyor belt 102. The limiting through hole 204 and the limiting vertical rod 105 are slidably matched to limit the adjustment frame 2 to only move up and down. The return spring 501 can provide a certain thrust for the dovetail slider 502. The dovetail slider 502 is subjected to the thrust and drives the tensioning wheel 503 to fit and squeeze the connecting belt 6, so that the connecting belt 6 is always kept in a tensioned state.

[0025] Among them, in order to achieve the purpose of pressing and fixing packages of different widths, the present device is implemented by adopting the following technical solutions: the pressing member 3 includes a mounting plate 301 and a threaded rod 302, a threaded column 303 is fixedly connected to the mounting plate 301, a fixing nut 305 is threadedly installed on the threaded column 303, a fixing countersunk hole 203 is provided on the inner wall of the pressing belt 202, the fixing countersunk hole 203 cooperates with the threaded column 303, a threaded through hole 304 is provided in the mounting plate 301, the threaded through hole 304 is threadedly matched with the threaded rod 302, a knob 306 is fixedly connected to one end of the threaded rod 302, and a circular contact pressure head 307 is fixedly connected to the other end of the knob 306.

[0026] Through the cooperation between the threaded column 303 and the fixed countersunk hole 203, after the threaded column 303 is passed through the fixed countersunk hole 203, the mounting plate 301 can be fixed on the pressing belt 202 by loosening the fixing nut 305. The threaded rod 302 is threadedly cooperated with the threaded through hole 304. The threaded rod 302 can be rotated by the knob 306 to adjust the extension length of the threaded rod 302, and then adjust the distance between the left and right circular contact heads 307, so that the circular contact heads 307 can press and fix packages of different widths.

[0027] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the package is placed on the conveyor belt 102, and the driving motor 103 is started to drive the first roller 101 to rotate. The rotation of the first roller 101 will drive the conveyor belt 102 to rotate, and the rotation of the conveyor belt 102 will drive the placed package to move. At the same time, the pressing piece 3 will rotate synchronously driven by the pressing belt 202. When the package moves to between the adjusting frame 2 and the bracket 1, the circular contact head 307 will press on the corner of the package, thereby pressing and fixing the package on the conveyor belt 102. Starting the drying fan 4 can blow out warm air to dry the surface of the package passing by.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
