Description

Technical Field

[0001] This utility model relates to the field of packaging box processing, and in particular to a paper flatness trimming device for packaging boxes. Background Technology

[0002] During the production of packaging boxes, paper (such as cardboard, corrugated paper, grey board, etc.) may warp or deform due to humidity, pressure, or processing techniques, affecting the quality of subsequent printing, die-cutting, and forming. Paper flatness correction devices are used to correct paper deformation and ensure that its flatness meets the requirements of packaging box production. Most existing technologies use roller pressing or flatbed hot pressing to apply uniform pressure to the paper to correct its deformation.

[0003] A search revealed Chinese Patent Publication No. CN219469157U, which discloses a paper leveling device for paper products. The device includes a leveling mechanism and a winding mechanism, which are arranged sequentially. The leveling mechanism includes a first frame, a tension control roller, and a guide roller. The tension control roller is located on one side of the frame, and the guide roller is located on the other side of the first frame. The tension control roller and the guide roller are arranged alternately. The tension control roller includes a first roller body and a magnetic powder clutch. The magnetic powder clutch is located at the end of the first roller body and is used to control the rotational speed of the first roller body. The winding mechanism includes a second frame and a winding roller. The winding roller is rotatably mounted on the second frame. The second frame is equipped with a winding roller adjustment mechanism for adjusting the axial position of the winding roller.

[0004] However, the rough edges produced during cutting and other debris generated during processing may fall onto the surface of the paper. During trimming, these debris will be pressed into the paper, causing indentations on the paper surface and affecting the trimming effect. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a paper flatness trimming device for packaging boxes includes a workbench 1. The top of the workbench 1 has a groove, and several conveying rollers 101 are arranged in the groove. The highest point of the conveying rollers 101 is lower than the highest point of the workbench 1, so as to facilitate the limiting of the paper through the groove. A conveying motor is fixedly connected to the front side of the workbench 1. The output end of the conveying motor is connected to one of the conveying rollers 101 through a coupling. Adjacent two conveying rollers 101 are driven by sprockets and chains, which will not be described in detail.

[0027] A trimming mechanism is provided above the workbench 1. The trimming mechanism includes two vertical plates 201 bolted to the top of the workbench 1. A shaping roller 202 is rotatably connected between the two vertical plates 201. A shaping motor 203 is bolted to one of the vertical plates 201. The output end of the shaping motor 203 is connected to the shaping roller 202 through a coupling. The position of the shaping roller 202 is set according to the thickness of the paper.

[0028] A cleaning mechanism is provided on one side of the trimming mechanism. The cleaning mechanism includes two upright plates 301 bolted to the top of the workbench 1. The two upright plates 301 are arranged one behind the other, and a brush roller 302 is rotatably connected between the two upright plates 301. The brush roller 302 is a hollow tubular shape, and two sets of air holes 401 are opened on the inner wall of the brush roller 302. The two sets of air holes 401 are symmetrically arranged and inclined towards both ends of the brush roller 302. The two upright plates 301 are fixedly connected. There is a stop bar 404, and a fan-shaped notch is opened on one side of the stop bar 404. The notch is located on the side of the stop bar 404 away from the trimming mechanism. The stop bar 404 is coaxially arranged with the brush roller 302. The outer wall of the stop bar 404 abuts against the inner wall of the brush roller 302. The direction and position of the air blowing out are controlled by the opening position of the groove on the stop bar 404. A discharge chute 102 is opened on the top of the worktable 1 to facilitate the smooth fall of the blown debris onto the worktable 1 and to facilitate the collection of debris.

[0029] The cleaning mechanism also includes a power assembly for driving the brush roller 302 to rotate. The power assembly includes a gear ring 303 fixedly connected to the outer wall of the brush roller 302. A rotating motor 304 is bolted to the rear side of the rear upright plate 301. A gear 305 is fixedly connected to the output shaft of the rotating motor 304, and the gear 305 meshes with the gear ring 303.

[0030] The cleaning mechanism also includes an air supply assembly for supplying air to the brush roller 302. The air supply assembly includes a fan 402 bolted to the rear side of the workbench 1. The air outlet of the fan 402 is fixedly connected to an air duct 403. The other end of the air duct 403 is fixedly connected to the rear upright plate 301 and communicates with a notch opened in the side wall of the baffle 404.

[0031] Working principle: In use, the paper is placed on the conveyor roller 101 and conveyed by the conveyor roller 101. Before the paper is trimmed, the rotating motor 304 is started first. The rotating motor 304 drives the gear 305 to rotate. The gear 305 meshes with the gear ring 303, thereby driving the gear ring 303 to drive the brush roller 302 to rotate, cleaning the paper surface and ensuring the trimming effect. At the same time, the blower 402 is started, and air is supplied into the brush roller 302 through the air duct 403. The air is blown out through the air hole 401, blowing the cleaned debris towards both ends of the brush roller 302, so that the debris is blown out of the worktable 1 through the discharge chute 102 for easy collection. Then the shaping motor 203 is started, and the shaping motor 203 drives the shaping roller 202 to rotate, trimming the curled edges of the paper.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
