[0024] See also Figure 1-4 The utility model provides a hydraulic paper cutter for producing corrugated paper boxes and convenient feeding, comprising a workbench 1, a first conveying assembly 2, a belt 3, a second conveying assembly 4, a pressing assembly 5 and a cutting assembly 6, wherein the first conveying assembly 2 comprises two conveying rollers 21, the two conveying rollers 21 are connected by a conveying belt 22, and one of the conveying rollers 21 is connected to a first motor 23;

[0025] The second conveying assembly 4 includes a rotating roller 41, a first motor 23 is connected to the back of the workbench 1, two conveying rollers 21 are rotatably connected in the workbench 1, and the rotating roller 41 is transmission-connected to the conveying roller 21 close to the rotating roller 41 through the belt 3. By setting the belt 3, the rotating conveying roller 21 can drive the rotating roller 41 to rotate synchronously through the belt 3;

[0026] A plurality of limit grooves 42 are provided in the rotating roller 41, and a second motor 43 is connected to the rotating roller 41. Two output shafts of the second motor 43 are connected to the threaded rod 44. The ends of the two threaded rods 44 that are away from each other are connected to the rotating roller 41 through bearings 46. The two threaded rods 44 are both threadedly connected to the limit plate 45. The thread directions of the two threaded rods 44 are opposite. By setting the threaded rods 44, the two threaded rods 44 that rotate synchronously can drive the two threaded plates to move closer to or away from each other.

[0027] The two limiting plates 45 are rotatably connected to the adjacent sides thereof. By providing the balls 47, when the two limiting plates 45 approach each other drive the balls 47 to contact the two sides of the paperboard, the limiting plates 45 can limit the paperboard through the balls 47. In this process, since the balls 47 are arranged between the paperboard and the limiting plates 45, the moving paperboard can drive the balls 47 to rotate in the limiting plates 45. The rotating balls 47 reduce the friction between the limiting plates 45 and the paperboard, so that the paperboard can move smoothly after being limited.

[0028] The two limiting plates 45 are respectively slidably connected in the plurality of limiting grooves 42. By providing the limiting grooves 42 and the limiting plates 45, since the limiting plates 45 are slidably connected in the plurality of limiting grooves 42, the plurality of limiting grooves 42 can limit the limiting plates 45, so that the limiting plates 45 will not rotate under the action of the rotating threaded rod 44, so that the limiting plates 45 can be smoothly moved in the limiting grooves 42 along the axial direction thereof under the action of the rotating threaded rod 44;

[0029] The pressing assembly 5 includes an electric push rod 51 and a pressing roller 52. The electric push rod 51 is clamped in the workbench 1. The bottom end of the electric push rod 51 is connected to the pressing roller 52. By setting the pressing roller 52, the pressing roller 52 moving downward can press the paperboard on the rotating roller 41, thereby increasing the friction between the paperboard and the rotating roller 41, so that the rotating rotating roller 41 can smoothly drive the paperboard to move;

[0030] The cutting assembly 6 includes a cutting knife 62 and two cylinders 61. The two cylinders 61 are clamped in the workbench 1. The bottom ends of the two cylinders 61 are connected to the same cutting knife 62. The pressing roller 52 is arranged above the rotating roller 41. The rotating roller 41 is arranged between the conveyor belt 22 and the cutting knife 62. The pressing roller 52 is arranged in the middle above the two limit plates 45.

[0031] The working principle and use process of the utility model are as follows: when the device needs to be used, a cardboard is placed on the conveyor belt 22, and the first motor 23 is controlled to work. The working first motor 23 drives one of the conveyor rollers 21 to rotate, and the rotating conveyor roller 21 can drive the rotating roller 41 to rotate synchronously through the belt 3. The rotating conveyor roller 21 drives another conveyor roller 21 to rotate through the conveyor belt 22, and the cardboard placed on the conveyor belt 22 can move to the rotating roller 41, and then the second motor 43 is controlled to work, and the working second motor 43 drives two threaded rods 44 to rotate synchronously, and the two rotating threaded rods 44 drive two limit plates 45 to approach each other, and the two limit plates 45 approaching each other both drive a plurality of The balls 47 are in contact with both sides of the cardboard respectively, and the working first electric push rod 51 drives the pressing roller 52 to move downward and then presses the cardboard outside and above the rotating roller 41, and then continues to control the first motor 23 to work. The cardboard after being limited moves between the pressing roller 52 and the rotating roller 41 and gradually moves to the bottom of the cutting knife 62. When the cardboard moves to a suitable position, the working hydraulic cylinder drives the cutting knife 62 to move downward. At this time, the first motor 23 stops working, and the cutting knife 62 moving downward can cut the cardboard. After the cardboard cutting is completed, and the cutting knife 62 moves upward under the action of the hydraulic cylinder, the first motor 23 continues to work, and then the cardboard on the conveyor belt 22 can be automatically loaded.
