Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, the present invention provides a corrugated paper packaging box stamping forming device, including a base 1, a fixed mold 2 and a support frame 3 are fixedly connected to the top of the base 1 respectively, the support frame 3 is located outside the fixed mold 2, a piston cylinder 4 is fixedly connected to the top of the support frame 3, the output end of the piston cylinder 4 extends into the interior of the support frame 3 and is fixedly connected to a moving plate 5, and a moving mold 6 is fixedly connected to the bottom of the moving plate 5.

[0024] The auxiliary mechanism includes a storage slot 7 on the top of the base 1, a heater 8 fixedly connected to the bottom inside the storage slot 7, an auxiliary plate 9 fixedly connected to the top of the heater 8 inside the storage slot 7, the top of the auxiliary plate 9 extending to the outside of the storage slot 7 and movably connected to the bottom of the fixed mold 2, a heat-conducting plate 10 fixedly connected to the bottom of the auxiliary plate 9, an exhaust mechanism on the front of the base 1, and a guide mechanism inside the support frame 3.

[0025] refer to Figure 5 The exhaust mechanism includes an exhaust pipe 11 fixedly connected to the front of the base 1. The back of the exhaust pipe 11 passes through the base 1 and extends into the interior of the storage slot 7. A one-way valve 12 located on the front of the base 1 is fixedly connected inside the exhaust pipe 11. The top of the one-way valve 12 extends to the outside of the exhaust pipe 11. A protective mechanism is provided on the surface of the exhaust pipe 11.

[0026] As a technical optimization of this utility model, by setting an exhaust pipe 11 and a one-way valve 12, the gas generated by water heating is discharged, so that the air pressure in the storage tank 7 is kept within a safe range, and the auxiliary plate 9 is prevented from bending and deforming due to excessive air pressure in the storage tank 7.

[0027] refer to Figure 5 The protective mechanism includes a buffer rubber 13 that is movably connected to the surface of the exhaust pipe 11 and located on the front of the base 1. A protective cover 14 is fixedly connected to the surface of the buffer rubber 13, and the back of the protective cover 14 is fixedly connected to the front of the base 1.

[0028] As a technical optimization of this utility model, by setting buffer rubber 13 and protective cover 14, the exhaust pipe 11 is protected to prevent the exhaust pipe 11 from being damaged due to worker's mistake by causing foreign objects to collide with the exhaust pipe 11.

[0029] refer to Figure 2 The guiding mechanism includes guide grooves 15 respectively opened on both sides inside the support frame 3, and sliding blocks 16 are fixedly connected to both sides of the moving plate 5. The outer side of the sliding block 16 extends into the interior of the guide groove 15, and a lubrication mechanism is provided on the surface of the sliding block 16.

[0030] As a technical optimization of this utility model, by setting the guide groove 15 and the sliding block 16, the moving plate 5 is guided and limited during the up and down movement of the moving plate 5, so as to avoid the moving plate 5 from shifting or tilting, thereby affecting the normal operation of the stamping forming device.

[0031] refer to Figure 3 The lubrication mechanism includes a mounting groove 17 opened on the outside of the sliding block 16. A solid lubricant 18 is fixedly connected inside the mounting groove 17. The outside of the solid lubricant 18 extends to the outside of the mounting groove 17 and is movably connected to the inner wall of the guide groove 15.

[0032] As a technical optimization of this utility model, by setting the mounting groove 17 and the solid lubricant 18, when the solid lubricant 18 rubs against the inner wall of the guide groove 15, the lubricant in the solid lubricant 18 will be transferred to the inner wall of the guide groove 15 to lubricate the sliding block 16 and reduce the wear of the sliding block 16.

[0033] refer to Figure 5 The back of the storage slot 7 is fixedly connected to a shielding frame 19 located at the bottom of the auxiliary plate 9. The shielding frame 19 is aligned with the exhaust pipe 11, and a hydrophobic membrane 20 is fixedly connected to the surface of the shielding frame 19.

[0034] As a technical optimization of this utility model, by setting a shield 19 and a hydrophobic membrane 20, water is prevented from entering the exhaust pipe 11. Since there is a certain distance between the shield 19 and the auxiliary plate 9, it will not hinder the gas from entering the exhaust pipe 11.

[0035] The working principle and usage process of this utility model are as follows: When in use, the corrugated paper is first placed on the fixed mold 2. At this time, the heater 8 is started, and the heater 8 heats the water in the storage tank 7. The water transfers heat to the fixed mold 2 through the heat-conducting plate 10 and the auxiliary plate 9. The fixed mold 2 heats the corrugated paper through the heat. Since the heat is transferred through water, the temperature is avoided from being too high and causing the corrugated paper to burn. Then, the piston cylinder 4 is started. The piston cylinder 4 drives the moving plate 5 and the moving mold 6 to move downward through the output end, and punches and bends the corrugated paper.

[0036] In summary, this corrugated cardboard packaging box stamping and forming device heats the water in the storage tank 7 by setting a heater 8. The water transfers heat to the fixed mold 2 through the heat-conducting plate 10 and the auxiliary plate 9. The heat is used to heat the corrugated cardboard, making its fiber structure softer and easier to shape. This avoids the corrugated cardboard from breaking at the bending point when the stamping and forming device is stamping and bending the cardboard, thus improving the practicality of the stamping and forming device.
