[0022] The present utility model provides a Figure 1 - Figure 4 A pressing device for cardboard production as shown in the figure, including a support plate 1. Two chutes 2 are opened in the middle of the top of the support plate 1. A support block 7 is slidably fitted in the two chutes 2. A limit box 8 is fixed at the top of the two support blocks 7. The two sides of the two chutes 2 are respectively fixed with a first support frame 3 and a second support frame 10. Two raw material rollers are rotatably connected inside the first support frame 3. A face paper raw material and a paper core raw material are arranged on the two raw material rollers. Two first motors 4 are fixed on one side of the first support frame 3. The two raw materials are respectively connected to the drive shafts of the corresponding first motors 4.

[0023] Through grooves 16 for the face paper raw material and the paper core raw material to pass through are opened on both sides of the limit box 8. A winding roller 11 is rotatably connected inside the second support frame 10. The winding roller 11 is used for winding the bonded face paper raw material and paper core raw material. A second motor is fixed on one side of the second support frame 10. The drive shaft of the second motor is connected to the winding roller 11.

[0024] Two raw material rollers can respectively wind one end of the facial tissue raw material and the paper core raw material. The facial tissue raw material and the paper core raw material can be pressed and smoothed by the limiting box 8 and then adhered together. After the pasting is completed, the finished raw material can be wound on the winding roller 11. By continuously rotating the winding roller 11, the facial tissue raw material and the paper core raw material can be pulled to move and paste.

[0025] During specific operation, glue can be placed on the side where the facial tissue raw material and the paper core raw material are close to each other for bonding.

[0026] The second motor can drive the winding roller 11 to rotate. The two first motors 4 can respectively drive the corresponding raw material rollers to release the facial tissue raw material and the paper core raw material, and they are used in cooperation with each other.

[0027] A U-shaped frame 9 is arranged at the top of the limiting box 8. An arc-shaped block 6 is fixed at the bottom end inside the through groove 16. An electric heating wire is arranged inside the arc-shaped block 6. A telescopic member 12 is fixed at the top end inside the U-shaped frame 9. The telescopic member 12 includes a telescopic rod and a second spring. The second spring is sleeved outside the telescopic rod. The bottom of the telescopic rod extends into the limiting box 8, and the bottom of the extending end is fixed with a pressing soft plate 5. When the facial tissue raw material and the paper core raw material pass through the through groove 16, the pressing soft plate 5 at the top will press the facial tissue raw material and the paper core raw material. Since the pressing soft plate 5 is provided with the telescopic member 12, according to different thicknesses, the pressing soft plate 5 can adapt, improving the scope of application. At the same time, the through groove 16 inside the limiting box 8 can limit and align the two sides of the facial tissue raw material and the paper core raw material, avoiding the effect of generating movement.
