DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the embodiment, Figure 1 A paperboard flattening device for packaging boxes is provided, comprising a frame 1, a paper feeding platform 2 is fixedly connected to the top of the frame 1, a flattening component 3 is arranged on the top of the frame 1, and a guide component 4 is arranged on the frame 1;

[0019] The leveling assembly 3 includes a stand 31, and two stands 31 are fixedly connected to the top of the frame 1. The two stands 31 are fixedly connected by four first connecting rods 32. A rotating shaft 33 is rotatably connected between the two stands 31, and a leveling roller 34 is fixedly connected to the outer side of the rotating shaft 33. Two slide rails 35 are fixedly connected to the opposite sides of the two stands 31, and a rotating seat 36 is slidably connected between the two adjacent slide rails 35. A clamping shaft 37 is rotatably connected between the two rotating seats 36, and a clamping roller 38 is fixedly connected to the outer side of the clamping shaft 37. Cylinders 39 are fixedly connected to the two stands 31, and the output ends of the two cylinders 39 respectively penetrate and extend to the inner sides of the two stands 31, and the output ends of the two cylinders 39 are respectively fixedly connected to the tops of the two rotating seats 36.

[0020] Through the above arrangement, first push the cardboard along the paper feeding platform 2 from left to right until the cardboard enters between the leveling roller 34 and the pressing roller 38, and start the two cylinders 39 at the same time. The output ends of the two cylinders 39 are simultaneously pushed out a suitable distance. At this time, the rotating seat 36 slides downward along the two slide rails 35 until the leveling roller 34 and the pressing roller 38 clamp the cardboard (not clamped), and continue to push the cardboard until the entire cardboard passes between the leveling roller 34 and the pressing roller 38. In the process of the cardboard passing between the leveling roller 34 and the pressing roller 38, the leveling roller 34 and the pressing roller 38 will rotate. After the cardboard completely passes between the leveling roller 34 and the pressing roller 38, it will fall above the guide component 4, slide downward through the guide component 4, slide to the top of the conveyor belt prepared in advance, and be transmitted to the next process through the conveyor belt.

[0021] Reference Figure 1 , wherein four foot pads 5 are fixedly connected to the bottom end of the frame 1;

[0022] Through the above-mentioned structural arrangement, the contact area between the four foot pads 5 and the ground is larger, so it is more stable compared with the four supporting feet of the rack 1 directly contacting the ground.

[0023] Reference Figure 1 , wherein the guide assembly 4 includes a fixed plate 41, two fixed plates 41 are fixedly connected to the frame 1, and the two opposite sides of the two fixed plates 41 are fixedly connected to an inclined plate 42, the two inclined plates 42 are fixedly connected by two second connecting rods 43, and the two inclined plates 42 are rotatably connected to two guide shafts 44, and the outer sides of the two guide shafts 44 are fixedly connected to two guide wheels 45;

[0024] With the above-mentioned structural arrangement, when the cardboard falls onto the four guide wheels 45 , the cardboard will slide downward due to the influence of gravity, and the two guide shafts 44 and the two guide wheels 45 will rotate.
