[0033] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of improving the strength of the present application is:

[0034] The carton is produced by the production method, and the carton includes a plane layer 01, a corrugated layer 02 and a mesh layer 03, the corrugated layer 02 is bonded to the upper and lower surfaces of the mesh layer 03, and the outer sides of the two corrugated layers 02 are bonded to the plane layer 01; the carton made of the packaging paper with the above structure can increase the strength of the packaging paper by using the mesh layer 03, increase the thickness of the packaging paper by using the mesh layer 03, and increase the tear resistance in the length direction and the width direction;

[0035] In addition, the mesh layer 03 is made of waterproof material, so that after the carton is soaked in water, although the plane layer 01 and the corrugated layer 02 are broken, the mesh layer 03 will not be broken and will remain in a stable state, so that the carton will not fall apart or break, and the carton will not break when it is moved, causing the objects inside to fall out, thereby improving the protection of the objects inside.

[0036] Another embodiment: the grid layer 03 is made of nylon material, which is not only waterproof but also has strong plasticity. It can maintain its own state when bending or folding, ensure the overall strength of the carton, avoid breakage or tearing of the packaging paper, and improve the strength of the manufactured carton.

[0037] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of applying glue in this application is:

[0038] The carton production method uses a production device, which includes a limit block 04, a middle hole 06 is opened in the middle of the limit block 04, two side holes 05 are opened on the limit block 04, respectively on the upper and lower sides of the fishtail middle hole 06, and a smear brush 09 is fixed on the upper and lower surfaces of each side hole 05. The interior of the limit block 04 is empty and has a leakage hole 10. Glue is poured into the limit block 04 and can flow into the smear brush 09 through the leakage hole 10. The limit block 04 is fixedly connected with a The valve 11 is connected to the inside of the limit block 04; the mesh layer 03 is passed through the middle hole 06 in the middle of the limit block 04 to the right, and the two corrugated layers 02 are passed through the two side holes 05 to the right respectively, so that the corrugated layer 02 can contact the two smear brushes 09 when passing through the side holes 05, so that the glue in the smear brush 09 is smeared on the upper and lower surfaces of the corrugated layer 02, thereby completing the automatic application of the glue, and at the same time, the two corrugated layers 02 can be moved to the upper and lower sides of the mesh layer 03 for positioning.

[0039] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of bonding of the present application is:

[0040] The upper and lower ends of the limit block 04 are rotatably connected to guide rollers 07, the right end of the limit block 04 is fixedly connected to the middle frame 12, the upper and lower ends of the middle frame 12 are slidably connected to clamping beams 13, the inner ends of the two clamping beams 13 are rotatably connected to squeeze rollers 14, and the squeeze rollers 14 are driven to rotate by a motor installed on the clamping beams 13, and a spring is fixedly connected between the clamping beams 13 and the middle frame 12. The plane layer 01 passes through the guide roller 07 from below, so that the two plane layers 01 are respectively located on the outside of the two corrugated layers 02, and then the grid layer 03 and the two corrugated layers 02 and the two plane layers 01 pass through the two squeeze rollers 14, the two squeezing rollers 14 can squeeze the mesh layer 03 and the two corrugated layers 02 and the two plane layers 01 under the action of the spring, so that the mesh layer 03 is pasted on the inner side of the two corrugated layers 02, and the two plane layers 01 are pasted on the outer side of the two corrugated layers 02, so as to realize the processing of the packaging paper. At the same time, the squeezing rollers 14 are driven by the motor to rotate, so that the two squeezing rollers 14 continuously twist the mesh layer 03 and the two corrugated layers 02 and the two plane layers 01, so that the mesh layer 03 and the two corrugated layers 02 and the two plane layers 01 move to the right, thereby completing the continuous processing of the packaging paper.

[0041] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of rapid prototyping of the present application is:

[0042] A drying box 15 is fixedly connected to the right end of the middle frame 12, a hot air blower 16 is fixedly connected to the front inner wall of the drying box 15, and a side hole 17 is opened on the rear inner wall of the drying box 15. When the packaging paper passes through the drying box 15, the hot air blown by the hot air blower 16 can enter the gap between the grid layer 03 and the two corrugated layers 02 and the two corrugated layers 02 and the two plane layers 01, thereby accelerating the drying of the glue, improving the forming speed of the packaging paper, and improving the processing efficiency of the packaging paper.

[0043] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of increasing the utilization rate of the present application is:

At this time, the recovered hot air can be introduced into the front frame 22, so that the mesh layer 03 and the two corrugated layers 02 passing through the front frame 22 can be blown out. The two plane layers 01 are dried and cleaned in advance, so that the moisture on the mesh layer 03, the two corrugated layers 02 and the two plane layers 01 can be evaporated faster and kept in a dry state, and the dust and impurities on the mesh layer 03, the two corrugated layers 02 and the two plane layers 01 can be blown away to avoid affecting the glue, and at the same time, the temperature of the mesh layer 03, the two corrugated layers 02 and the two plane layers 01 can be increased, which can facilitate the evaporation of moisture in the glue when applying and pasting the glue, and further improve the processing efficiency;

[0045] The upper and lower ends of the front frame 22 are rotatably connected to limit rollers 23, which can avoid contact and scratches on the front frame 22 when the grid layer 03, the two corrugated layers 02 and the two plane layers 01 move.

[0046] Refer to the attached Figures 1 to 8 From the structure shown, it can be understood that an exemplary operation process of improving flatness of the present application is:

The front and rear ends of the two trowel plates 19 are respectively in surface contact with the inner wall of the drying box 15. The inner end surface of the trowel plate 19 is arc-shaped. The grid layer 03, the two corrugated layers 02 and the two plane layers 01 are bonded after drying, and then move to the right through the two trowel plates 19, so that the two trowel plates 19 can complete the smoothing of the two plane layers 01 after bonding, and the surface of the packaging paper obtained after bonding can be smoother.
