[0023] A double-sided edge clamping assembly 7 is installed at the top of the conveying frame 6, which is located inside the drying device 3. The double-sided edge clamping assembly 7 includes a clamping bar 71 slidably connected to the top of the conveying frame 6. A pressure rod 78 is slidably connected to one end of the clamping bar 71, and a roller 79 is equidistantly connected to the pressure rod 78 for rotation. L-shaped plates 710 are staggered and fixedly installed on the opposite surfaces of the two clamping bars 71, and an extrusion cylinder 711 is rotatably connected inside the L-shaped plate 710. The top of the pressure rod 78 is located between the two rollers 79 and is fixedly installed with an edge heating assembly 8.

[0024] like Figure 2 and Figure 3 As shown, one side of the top of the clamping bar 71 is connected to a bidirectional threaded rod 72 by a thread, and the bidirectional threaded rod 72 drives the object to move relatively. A positioning column 73 is connected to the other side of the top of the clamping bar 71. The positioning column 73 is used to position the object. Both sides of the outer surface of the positioning column 73 and the bidirectional threaded rod 72 are connected to a fixing block 74 fixedly installed between the tunnel box of the drying device 3. The fixing block 74 is used for the installation of the positioning column 73 and the bidirectional threaded rod 72. The positioning column 73 and the fixing block 74 are clamped and connected. The threaded rod 72 and the fixed block 74 are rotationally connected, and circular rings are symmetrically clamped and installed on both sides of the outer surface of the bidirectional threaded rod 72. Horizontal plates 75 are symmetrically welded on the inner wall of the clamping strip 71, and screw rods 76 are threadedly connected inside two relative horizontal plates 75. The other two horizontal plates 75 are connected by cylinders 77 passing through the inside. The bottom end of the cylinder 77 and the top end of the pressure rod 78 are welded and connected. The screw rod 76 is used to drive the pressure rod 78 to move up and down, and is limited by the cylinder 77. The bottom end of the screw rod 76 and the top end of the pressure rod 78 are rotationally connected.

[0025] like Figure 2 and Figure 4 As shown, the edge heating assembly 8 includes an air outlet pipe 86 fixedly installed inside the pressure rod 78, the air outlet pipe 86 is used for the flow of gas, a three-way pipe 83 is fixedly installed on the top of the air outlet pipe 86, the three-way pipe 83 is used to divert the gas, a guide cover 81 is fixedly installed on the top of the three-way pipe 83 and the guide cover 81 is fixedly installed on one end face of the tunnel box of the drying device 3 by screws, the guide cover 81 is used to guide the hot air discharged from the drying device 3, a guide pipe 82 is fixedly installed on the top of the guide cover 81, one end of the three-way pipe 83 and one end of the hose 84 are fixedly connected for the flow of gas, which changes the difficulty of the gas flowing along the three-way pipe 83 and the hose 84.

[0026] Working principle: During the actual use of the device, the personnel rotate the bidirectional threaded rod 72, and the bidirectional threaded rod 72 rotates inside the fixed block 74. At this time, the two clamping strips 71 are driven to approach each other and fit the outer side of the color box under the limiting action of the positioning column 73. Then the personnel rotate the screw rod 76. When the screw rod 76 rotates, the pressure rod 78 moves downward steadily under the limiting action of the cylinder 77. When the pressure rod 78 moves, it drives the extrusion cylinder 711 to move downward synchronously through the L-shaped plate 710, and at this time, the pressure rod 78 drives the roller 7 9 moves downward, and the roller 79 fits with the edge of the color box after the movement, and at this time, the middle of the color box and the middle position of the top of the extrusion cylinder 711 fit each other, which can position the two sides of the color box to prevent the paper box from being offset due to the blowing of gas during the drying process inside the drying device 3, and can press the edge of the color box before drying and the middle of the color box after drying, so that the color box is more flat, and the position of the positioning and pressing mechanism can be adjusted, so as to be suitable for color boxes of different sizes, increasing its application range;

[0027] And because the air blown by the drying device 3 to the color box flows upward and is discharged outward along the outer side of the tunnel box of the drying device 3, the discharged air at this time enters the inside of the guide pipe 82 along the guide cover 81, and at this time the air enters the inside of the three-way pipe 83 along the guide pipe 82, and enters the inside of the hose 84 along the three-way pipe 83, and finally enters the inside of the air outlet pipe 86 through the guide cover 85, and enters the edge of the color box along the air outlet pipe 86, thereby achieving the purpose of blowing and drying the edge of the color box, and solving the problem that the edge of the color box is inconvenient to dry due to the use of the pressure rod 78 to press the edge of the color box;

[0028] Finally, the color box is placed into the frame 1. At this time, the color box enters the gluing device 2 along the frame 1. The gluing device 2 glues the color box. The glued color box enters the drying device 3, and the double-sided edge clamping component 7 in the drying device 3 limits the color box on both sides. At the same time, the edge of the color box is heated by the edge heating component 8. The heated color box enters the window film pasting device 4, and after processing in the window film pasting device 4, it enters the magnet and iron sheet pasting device 5. Finally, after processing along the magnet and iron sheet pasting device 5, the processing of the color box is ended, and the processed color box is collected by the collecting device.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
