Technical Field

[0001] The utility model relates to the technical field of cardboard transportation, in particular to a cardboard unloading mechanism with a leveling function. Background Art

[0002] Cardboard is a thick paper sheet made of various pulps, various plant fibers, and sometimes mixed with non-plant fibers, on a cardboard machine. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard with a basis weight of more than 250g / m2 and a thickness greater than 0.5mm is called cardboard. After the cardboard is produced, it needs to be stacked and packaged.

[0003] In the prior art, when the cardboard is conveyed, the rollers or belts may shake in different degrees horizontally, causing the cardboard to be misaligned, and the cardboard may also be misaligned when stacked up and down, resulting in the need to spend time to sort them before packaging.

[0031] A conveyor belt 4 is arranged on the side of the collecting part 1 to convey the cardboard into the collecting part 1. A collecting box 101 is arranged in the collecting part 1. The collecting box 101 is a rectangular box body with an opening on the top. A guide block 102 is arranged on the side of the collecting box 101 close to the conveyor belt 4. The top of the guide block 102 is lower than the conveying surface of the conveyor belt 4. The top of the guide block 102 is arranged with an inclined surface to guide the cardboard to fall into the collecting box 101. The driving part 2 is arranged on the outside of the collecting box 101. The driving part 2 includes a support frame 201 arranged on the outside of the collecting box 101, a power shaft 202 rotatably arranged inside the support frame 201, a driving shaft 203 arranged on the power shaft 202 and an electric The machine 205 has several support frames 201, and two power shafts 202 are provided. The two power shafts 202 pass through the support frame 201 and are rotatably connected thereto. The output end of the motor 205 is connected to the power shaft 202 to drive the power shaft 202 to rotate inside the support frame 201. The leveling part 3 is arranged inside the collecting box 101. The leveling part 3 includes a push frame 301 slidably connected to the collecting box 101 and a push plate 303 slidably arranged at the end of the push frame 301. The two power shafts 202 are driven to rotate by the motor 205 arranged inside the driving part 2, and then the pushing shaft 203 rotating on the power shaft 202 pushes the push frame 301 to move inside the collecting box 101, so that the push plate 303 pushes the edge of the stacked cardboard.

[0032] Embodiment 2

[0033] See also Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a cardboard unloading mechanism with a flattening function, comprising a driving part 2, a power shaft 202 and a bevel gear 204:

[0034] There are two power shafts 202, and bevel gears 204 are set at one end of the two power shafts 202. The two bevel gears 204 are meshed and connected with each other, so that when one of the power shafts 202 is driven by the motor 205 to rotate on the support frame 201, the other power shaft 202 will also rotate at the same speed, thereby enabling the driving shaft 203 set on the power shaft 202 to rotate at the same speed.

[0035] Embodiment 3

[0036] See also Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a cardboard unloading mechanism with a leveling function, comprising a leveling part 3, a push frame 301 and a push plate 303:

[0037] The leveling parts 3 are provided with two, and the leveling parts 3 include a push frame 301 and a push plate 303 slidably arranged at the end of the push frame 301. The push frame 301 is provided with an arc-shaped panel on the side close to the push shaft 203 facing outward. Two cylinders passing through the side wall of the collection box 101 are provided in the middle position of the push frame 301. There is a sliding structure between the push frame 301 and the collection box 101. A spring a302 is provided between the push frame 301 and the collection box 101. The rotation of the power shaft 202 drives the push shaft 203 to rotate, so that the rotating push shaft 203 contacts the arc surface and pushes the push frame 301 to move inside the collection box 101. When the push shaft 203 leaves the arc surface, the push frame 301 is reset under the action of the spring a302, and the push frame The push plate 303 is slidably connected with the push frame 301, and the spring b304 is between the push frame 301 and the push plate 303. The push plate 303 faces the inner side of the collection box 101. When the push frame 301 moves, it can drive the push plate 303 to move. When the push plate 303 contacts the edge of the cardboard, the push plate 303 will slide along the push frame 301. After the push plate 303 leaves the edge of the cardboard, the push frame 301 will reset under the action of the spring b304, thereby preventing the push plate 303 from contacting and pushing the cardboard, causing squeezing of the cardboard. The bottom surface of the push plate 303 abuts against the bottom surface of the inside of the collection box 101. The push plate 303 is perpendicular to the bottom surface of the inside of the collection box 101, and can push the cardboard that falls into the collection box 101.

[0038] Working principle: First, the cardboard is transported to the collection box 101 through the conveyor belt 4 arranged on one side of the collection part 1. The collection box 101 is a rectangular box body with an opening on the top. A guide block 102 is arranged on the side of the collection box 101 close to the conveyor belt 4, which can guide the cardboard to fall into the collection box 101. Then the driving motor 205 drives the power shaft 202 connected thereto to rotate. Through the mutual engagement of the two bevel gears 204, when one of the power shafts 202 is driven by the motor 205 to rotate on the support frame 201, the other power shaft 202 will also rotate at the same speed, so that the rotating driving shaft 203 contacts the arc surface and pushes the push frame 301 to move inside the collection box 101. The push plate 303 will push the cardboard that falls into the collection box 101, so that the edges of the stacked cardboards are flat, which is convenient for subsequent packaging.
