The number of rubber rollers 3 is six, and the six rubber rollers 3 are arranged in three groups equidistantly above and below. The back of the machine shell 2 is provided with a driving device for driving the six rubber rollers 3. By arranging six rubber rollers 3 and arranging them in three groups equidistantly above and below, the design can ensure that the glue can be evenly and fully applied to the paperboard when the paperboard passes through, thereby improving the gluing efficiency.

[0026] To realize high-pressure compounding of paperboard, a compounding mechanism for paperboard compounding is arranged on one side of the outside of the machine shell 2. The compounding mechanism comprises a support 4, a compounding roller 5 rotatably installed on the inner side of the support 4, and a driving structure arranged outside the base 1 for driving the compounding roller 5. The number of compounding rollers 5 is two, and an electric telescopic rod 16 is arranged above the top compounding roller 5. Specifically, the number of the support 4 and the compounding roller 5 is two, and the two compounding rollers 5 are distributed above and below. The top side of the outer surface of the machine shell 2 is welded with a mounting table, the electric telescopic rod 16 is fixed on the mounting table by bolts, and the output end of the electric telescopic rod 16 penetrates the inside of the mounting table and is fixed with the upper surface of the top support 4. The design of the electric telescopic rod 16 makes the height of the top compounding roller 5 adjustable according to actual needs, so as to change the compounding pressure. This flexibility makes the device adapt to the compounding needs of paperboards with different thicknesses and materials, improving the versatility and applicability of the equipment.

[0027] To realize the conveying of paperboard, the driving structure comprises a driving motor 10 arranged above the base 1, a transmission shaft 11 fixed to the output shaft of the driving motor 10, and gear parts arranged outside the transmission shaft 11. The number of gear parts is two, and the two gear parts correspond to the two compounding rollers 5 respectively. Specifically, the gear parts are composed of a driving gear 12 and a driven gear 13 meshing with each other. The bottom end of the transmission shaft 11 is connected with the upper surface of the base 1 through a bearing, a vertical plate 9 is welded on the upper surface of the base 1, and a motor seat fixed with one side of the vertical plate 9 is welded outside the driving motor 10.

[0028] The two gear parts are distributed above and below. The bottom driving gear 12 is fixed to the outer surface of the transmission shaft 11, the bottom driven gear 13 is fixed to one end of the bottom compounding roller 5, the top driving gear 12 is internally fixed with a spline sleeve 14 connected with the transmission shaft 11 through spline, the top driven gear 13 is fixed to one end of the top compounding roller 5, and the outer surface of the spline sleeve 14 is rotatably installed with a connecting plate 15 fixed with one side of the top support 4.

This connection mode not only ensures the stability of transmission, but also allows the top compounding roller 5 to move up and down under the action of the electric telescopic rod 16 without affecting the normal work of the transmission system.

[0029] In order to improve the composite effect of the paperboard, the outer part of the machine shell 2 is further provided with a drying device 6 used in cooperation with the composite mechanism; the drying device 6 comprises a box body 61 fixed to the outer surface of the machine shell 2, a fan 62 fixed to one side of the box body 61, and a resistance heating wire 63 fixed to the inside of the box body 61; the side of the machine shell 2 close to the composite mechanism is provided with two spray pipes 7, and a three-way pipe 8 is fixed between the two spray pipes 7 and the box body 61; the inside of the machine shell 2 is hollow, and both sides thereof are through. The drying device 6 heats air through the resistance heating wire 63 in the box body 61, and the fan 62 promotes the circulation of hot air, so that the spray pipe 7 can blow out hot air. The hot air directly acts on the composite paperboard, accelerating the drying process of the glue. The glue quickly solidifies, which can enhance the composite strength of the paperboard and improve the composite quality. Among them, the two spray pipes 7 are respectively fixed to the same side of the outer surface of the two supports 4. The inside of the box body 61 is provided with a temperature sensor.

[0030] The working principle of the above embodiment is as follows:

[0031] The six glue rollers 3 arranged in the inside of the machine shell 2 are responsible for evenly applying glue on the paperboard. The glue rollers 3 are driven to rotate by the driving device at the back of the machine shell 2, ensuring that the glue is evenly distributed on the paperboard. The paperboard after being coated with glue enters the composite mechanism, which is composed of two supports 4 and two composite rollers 5 and is distributed up and down. The top composite roller 5 can adjust the height through the electric telescopic rod 16 to adapt to paperboards of different thicknesses, ensuring uniform composite pressure. The paperboard passes between the two composite rollers 5, and due to the viscosity of the glue, the two layers of paperboard are tightly combined together. The composite paperboard is dried by the spray pipe 7. The spray pipe 7 is connected to the box body 61 through the three-way pipe 8. The inside of the box body 61 is provided with the resistance heating wire 63, and the outside has the fan 62 to promote the circulation of hot air. The hot air blows towards the composite paperboard through the spray pipe 7, accelerating the drying of the glue and making the paperboard quickly set.
