[0022] The utility model provides a bending device for processing honeycomb paperboard through improvement. The technical solution of the utility model is:

[0023] like Figure 1 - Figure 2As shown, a bending device for processing honeycomb paperboard comprises a processing table 1, and support legs 5 are fixedly installed at the four corners of the bottom wall of the processing table 1. A fixing assembly 2 is arranged on the top of the processing table 1, and the fixing assembly 2 comprises a fixing frame 21 fixedly installed on the side wall of the processing table 1, and a lower pressing rod 22 is slidably connected to the top wall of the fixing frame 21, and a lower pressing plate 25 is fixedly installed on the bottom wall of the lower pressing rod 22, and a limiting disk 23 is fixedly installed on the top wall of the lower pressing rod 22, and a fixing spring 24 is sleeved on the top end of the side wall of the lower pressing rod 22, and the upper and lower ends of the fixing spring 24 are fixedly connected to the top wall of the fixing frame 21 and the bottom wall of the limiting disk 23 respectively; by lifting the limiting disk 23 upward, a certain gap is made between the lower pressing plate 25 and the top wall of the processing table 1, and the honeycomb paperboard to be processed is placed between the lower pressing plate 25 and the processing table 1, and the elasticity of the fixing spring 24 is used to move the lower pressing plate 25 downward to press the top of the honeycomb paperboard to ensure that the honeycomb The position of the cardboard is stable. A processing assembly 3 is provided on the top of the processing table 1. The processing assembly 3 includes a processing push rod 31 fixedly installed on the top wall of the processing table 1. A connecting rod 32 is rotatably installed on the output end of the processing push rod 31. A positioning rod 34 is fixedly installed on the side wall of the connecting rod 32. A guide plate 33 is fixedly installed on the side wall of the positioning rod 34 away from the processing push rod 31. The side wall of the guide plate 33 away from the processing push rod 31 is inclined. A receiving groove 36 aligned with the side wall of the fixed frame 21 is opened on the top wall of the processing table 1; through the extension of the output end of the processing push rod 31, the guide plate 33 shovels up the bottom end of the honeycomb cardboard as the output end of the processing push rod 31 extends, so that the honeycomb cardboard is bent. When the guide plate 33 moves to the top of the receiving groove 36, the guide plate 33 rotates around the connecting rod 32. Therefore, the guide plate 33 is inside the receiving groove 36, so that the side wall of the positioning rod 34 fits with the side wall of the honeycomb cardboard to ensure the bending of the honeycomb cardboard.

[0024] like Figure 3 As shown, in one embodiment, in order to facilitate the guide plate 33 to scoop up the honeycomb paperboard, a stirring assembly 4 is arranged inside the processing table 1, and the stirring assembly 4 includes a stirring groove 43 provided at the center position of the top wall of the processing table 1, the stirring groove 43 is connected to the accommodating groove 36, and a stirring plate 41 of an arc-shaped plate is arranged inside the stirring groove 43, and a mounting groove 42 aligned with the stirring groove 43 is provided on the side wall of the guide plate 33, and one end of the stirring plate 41 close to the processing push rod 31 is rotatably mounted inside the mounting groove 42, and a plurality of stirring pads 44 are fixedly installed at equal intervals on the inner bottom wall of the stirring plate 41; when the output end of the processing push rod 31 pushes the guide plate 33 to move toward the fixing assembly 2, the side wall of the stirring plate 41 contacts the side wall of the stirring pad 44, so that the stirring plate 41 rotates upward to lift the honeycomb paperboard, which facilitates the guide plate 33 to lift the honeycomb paperboard, and the stirring plate 41 is repeatedly hit against the bottom of the honeycomb paperboard through the plurality of stirring pads 44, so that the honeycomb paperboard is repeatedly bent, which facilitates the shaping of the honeycomb paperboard.

[0025] like Figure 1 - Figure 3 As shown, in one embodiment, in order to prevent the positioning rod 34 from having an excessively large range of motion and being unable to fit well with the honeycomb paperboard, a limiting plate 35 is fixedly installed on the side wall of the output end of the processing push rod 31, and the limiting plate 35 fits with the side wall of the positioning rod 34; the limiting plate 35 limits the rotation range of the positioning rod 34 to ensure that the positioning rod 34 can fully fit with the side wall of the honeycomb paperboard.

[0026] The specific working method is as follows: by lifting the limit plate 23 upward, there is a certain gap between the lower pressing plate 25 and the top wall of the processing table 1, the honeycomb paperboard to be processed is placed between the lower pressing plate 25 and the processing table 1, and the lower pressing plate 25 is moved downward by the elasticity of the fixing spring 24 to press the top of the honeycomb paperboard to ensure the stability of the position of the honeycomb paperboard. By extending the output end of the processing push rod 31, the guide plate 33 scoops up the bottom end of the honeycomb paperboard as the output end of the processing push rod 31 extends, so that the honeycomb paperboard is bent. When the guide plate 33 moves to the top of the receiving groove 36, the guide plate 33 is moved to the top of the receiving groove 36. The plate 33 will rotate around the connecting rod 32, so the guide plate 33 is located inside the accommodating groove 36, so that the side wall of the positioning rod 34 fits with the side wall of the honeycomb paperboard to ensure the bending of the honeycomb paperboard. When the output end of the processing push rod 31 pushes the guide plate 33 to move toward the fixed component 2, the side wall of the stirring plate 41 contacts the side wall of the stirring pad 44, so that the stirring plate 41 rotates upward to lift the honeycomb paperboard, making it easier for the guide plate 33 to lift the honeycomb paperboard. Through multiple stirring pads 44, the stirring plate 41 repeatedly hits the bottom of the honeycomb paperboard, so that the honeycomb paperboard is repeatedly bent, which facilitates the shaping of the honeycomb paperboard.
