And, if nothing is exceptional, the left side of the arrival direction facing the conveying direction is left (i.e., the side further to the outside in fig. 1 is left) with the front in the conveying direction being front and the reverse being rear.
Embodiment 1 as shown in fig. 1 and 2, this embodiment provides a board 11 edge covering device, which includes a first edge covering mechanism 2, a second edge covering mechanism 4, and a material transferring mechanism, where the first edge covering mechanism 2 is used to attach a pair of side edges of a covering edge covering material to the upper surface of the board 11, the second edge covering mechanism 4 is used to attach another pair of side edges to the upper surface of the board 11, and the four corner edges are also particularly attached to the side walls of the board 11, so as to realize overall edge covering of the side walls of the board 11, and place the side walls or the corners thereof exposed.
The first edge wrapping mechanism 2 and the second edge wrapping mechanism 4 are preferably arranged vertically, on one hand, a device for exchanging the angle of the paper board 11 does not need to be arranged particularly in the process of transferring the paper board 11 from the first edge wrapping mechanism 2 to the second edge wrapping mechanism 4, and on the other hand, the overall length of the device can be reduced so as to adapt to installation and use in a factory building with limited use space.
Referring to fig. 3 and 4, the first hemming mechanism 2 includes a conveying unit and a hemming unit, and the second hemming mechanism 4 includes a conveying unit, a hemming unit, and a corner-forming unit.
The conveying unit is divided into a left conveying mechanism 210 and a right conveying mechanism 220, the left conveying mechanism 210 and the right conveying mechanism 220 are basically identical in structure and are oppositely arranged at intervals, and the interval between the left conveying mechanism 210 and the right conveying mechanism 220 is preferably capable of accommodating the paper boards 11 to pass through. Taking the right conveying mechanism 220 which can be shown clearly in fig. 4 as an example, it includes a right conveying bottom rail 416 and a right conveying narrow belt 414, two sides of the right conveying bottom rail 416 are respectively provided with a right conveying driven wheel 418, the right conveying narrow belt is sleeved on the two right conveying driven wheels 418 and rotates continuously, and the conveying part above the right conveying narrow belt is just embedded in the conveying groove in the upper surface of the right conveying bottom rail 416, and the groove bottom of the conveying groove forms a rigid support for placing the right conveying narrow belt 414. As can be seen from fig. 1 and 2, in this embodiment, the main shaft 443 spans the left conveying mechanism and the right conveying mechanism, and the rotation of the main shaft 443 is a power source of the conveying unit. In order to keep the right conveying belt 414 in a tensioned state and ensure the conveying speed and efficiency, in another embodiment, a right tensioning wheel 419 a and a right tensioning wheel 419 b may be disposed in the path of the right conveying belt 414, especially on both sides of the right conveying driving wheel 413.
In this embodiment, the right conveying belt 414 can be a driving belt, a right conveying driven wheel 418, a right conveying driving wheel 413, and a right tension wheel 419.
The folding unit is configured to fold a pair of side edges of the covering and edge-wrapping material and attach the side edges to an upper surface of the paper board 11 opposite to one surface, and folding mechanisms corresponding to the positions are respectively disposed on the conveying units of the left conveying mechanism and the right conveying mechanism of the second edge-wrapping mechanism 4, taking the right conveying mechanism as an example, the folding mechanism mainly includes a right guide block 415, and the right guide block 415 is formed with or has a guide surface 415a for raising and bending the side edge from a horizontal direction, as shown in fig. 13, the guide surface 415a is a twisted surface formed by smooth transition from the horizontal direction to a vertical direction and then to horizontal transition. As shown in fig. 14, when the paper sheet 11 attached to the covering packaging material passes through, the side edge is guided by the guide surface 415a, and the side edge is turned over vertically and then horizontally, so that the side edge of the passing covering packaging material is turned over together with the side wall and another surface (the upper surface is shown in the drawing, and the upper and lower positions can also be turned over horizontally in practical application, but considering that the covering packaging material is coated with glue, the structure shown in the drawing is often adopted for convenience of application) of the paper sheet 11 to complete the edge folding action.
As shown in fig. 5 and 6, the right angle-bending unit 411 of the second hemming mechanism 4 is disposed adjacent to the hemming unit and behind the hemming unit, and the angle-bending unit is used to perform hemming of a corner edge. Because the four corner edges of the covering edge-covering material are respectively arranged at the four corners, and the paper board 11 is mainly square in the embodiment, a left corner-making unit and a right corner-making unit are respectively arranged at the inlets of the left conveying mechanism and the right conveying mechanism, and the left corner-making unit and the right corner-making unit have the same structure and are correspondingly positioned.
Referring to fig. 10-11, in this embodiment, the left and right angling units include a mounting bracket 411a, an angling block 411h, a driver, a swing shaft 411c, a first pin 411f, a second pin 411e, and a swing block 411d, where the angling block 411h is an L-shaped structure, a corner thereof is a middle portion, and one end thereof is provided with a flat structure perpendicular to the side, i.e., the angling head 411i, which can be inserted into a gap between the paper board 11 and a rail blocking wall of the left or right conveying mechanism, as shown in fig. 12.
The middle part of the angle block 411h and the end part of the other end (i.e. the linkage end) thereof are provided with pin holes: the pin hole in the middle part is matched with the swing shaft 411c and can be rotatably fixed in a connecting hole I at one end of the swing shaft 411c, the pin hole in the linkage end is also fixed in a connecting hole II of the swing shaft 411c through a pin shaft II 411e, and the connecting hole I is closer to the connecting hole II. Meanwhile, the other end of the swing shaft 411c is a fixed end, which is rotatably fixed on the mounting bracket 411a through a first pin 411 f.
In this embodiment, the driver adopts a small air cylinder 411b, a fixed end of the small air cylinder 411b is hinged on the mounting bracket 411a, a movable end of the small air cylinder 411b is hinged on a second pin shaft 411e, and the movable end of the small air cylinder 411b can drive the other end of the angle block 411h and the middle area of the angle block 411h to swing by taking the swing shaft 411c as the center along with the telescopic action. And then the linkage end of the angle block 411h is controlled to swing and drive the angle head 411i to enter or exit the conveying range of the conveying unit, so that the erected angle edge 1101 is pushed into the gap between the paper board 11 and the rail retaining wall along the conveying direction, the angle edge 1101 is attached to the side wall of the paper board 11, and angle wrapping is realized.
In this embodiment, as shown in fig. 1, the material transferring mechanism 3 adopts a vacuum adsorption material transferring mechanism, which includes a vacuum adsorption part, a lifting structure part 320 and a horizontal motion structure part 310, and the material transferring mechanism 3 can effectively ensure the positioning accuracy of the material transferring process, ensure that the material transferring process is not deviated and timely, so as to realize the action synchronization with the first edge covering mechanism 2 and the second edge covering mechanism 4, especially with the angle forming mechanism, ensure the consistent processing rhythm, further ensure the processing efficiency and improve the yield.
Based on the above, it is specifically explained that for the covering edge-covering dressing of the square paper board 11, the connection relationship between the corner edge and the side edge is as follows: one, four corner sides link with one pair of side; two of the four corner edges are paired pairwise and are linked with the same pair of side edges respectively. In the former case, the four corner edges 1101 (a pair of corner edges on the front side and the side edges are folded together by the folding mechanism to perform a corner attaching operation) and the operation of folding the pair of side edges 1103 can be completed by one processing of the folding and hemming mechanism of the sheet 11 according to the present embodiment.
Therefore, in another embodiment, for the second case, the same structure as the second edge wrapping mechanism 4 may be adopted instead of the first edge wrapping mechanism 2, so as to achieve the overall wrapping of four corners and four sides of the paper board 11.
Example 2 this example differs from example 1 in that: for enhancing the tightness of the side edges against the cardboard 11, the following edge pressing mechanism can be provided: still take the right conveying mechanism as an example, in this embodiment, the edge pressing mechanism is located behind the edge folding mechanism and is disposed on the right conveying narrow belt 414, and a pressing member in clearance fit with the right conveying narrow belt 414 is disposed on the edge pressing mechanism, and the clearance is adapted to the thickness of the paper board 11 to be processed, so that, in the process of continuing conveying the right conveying narrow belt 414, the folded side edge can be tightly attached to the upper surface of the paper board 11, and thus the reliability of the edge covering operation of the side edge can be ensured. Of course, one possible embodiment of the pressing member shown in the drawings is a row of right rollers 417 evenly spaced apart, the right rollers 417 being in clearance fit with the upper surface of the right belt 414, the clearance being adapted to the thickness of the sheet 11 to be processed (preferably slightly less than or equal to the thickness of the sheet 11).
As a specific structure, the flattening mechanism 5 includes a conveying belt 512, a rotating roller for driving the conveying belt 512, and a pressing roller 511 engaged with the upper surface of the conveying belt 512, and certainly, in order to ensure the squeezing effect, a engaging roller or an engaging plane is provided below the conveying belt 512 in clearance fit with the pressing roller 511, so that each part of each paperboard 11 (including the covering material) passing through the clearance is uniformly pressed, and the side edge is tightly attached to the upper surface of the paperboard 11.
Therefore, in this example, the width of the conveyor belt 512 is not less than the width of the paper sheet 11, and the gap between the press roller 511 and the matching roller and the matching plane is slightly less than or equal to the thickness of the paper sheet 11.
The driven wheel 442 is mounted on a rotating shaft which rotates synchronously with the rotating rollers of the flattening mechanism 5 through a coupling 514, and in another embodiment, in consideration of keeping the transmission force stable and changing the rotating speed of the rotating shaft, the driving linkage can be realized by changing the size of the outer diameter of the driven wheel 442 or adding a third triangular transmission structure 513 between the rotating shaft and the pressing roller 511.
Alternatively, in still another embodiment, driving means may be provided for the conveying unit and the flattening mechanism 5, respectively, or a driving means may be further provided for the left conveying mechanism and the right conveying mechanism, respectively.

The conveying side wall has the following functions that the conveying side wall is in contact with the side wall of the paper board 11 in the process of edge pressing or outputting the paper board 11 after edge covering: on one hand, the paper conveying plate 11 can be helped to move forwards continuously to counteract the resistance caused by part of the edge pressing mechanism; on the other hand, the contact process can be utilized to further attach the side edges or the corner edges on the material to the paper board 11, so that the reliability of edge covering is ensured.
