Background
In the production and processing of the paperboard, many steps require gluing on the paperboard, such as gluing of the core paper and the face paper of the paperboard, laminating of the surface of the paperboard and the like, and with the development of technology, the gluing of the paperboard is mechanically processed.
Chinese patent No. cn201610015631.x discloses a cardboard gluing machine, which comprises a frame, the both sides top surface of the platen of frame is fixed with two vertical boards, the both sides bottom surface of platen is fixed with the backup pad, the both ends of underdrive compression roller articulate in two backup pads, the microscler logical groove that the middle part of platen has is overlapped in the underdrive compression roller plug bush, the top surface of platen is stretched out on the upper portion of underdrive compression roller, the upper portion and the lower part of the lateral wall of vertical board are fixed with the connecting plate, adjusting screw's both ends articulate on two connecting plates, adjusting screw's upper end stretches out the connecting plate on upper portion and is fixed with the rolling disc, the middle part of vertical board has vertical regulation and leads to the groove, the both ends of going up the transmission compression roller pass vertical regulation and lead to the groove and articulate on. The synchronous lifting and descending of the upper press roller and the gluing groove can be realized, so that the uniformity of gluing is ensured, and the gluing effect is improved. When the automatic gluing machine is used, a paper board is placed on a platen, the paper board is manually pushed by a person to be positioned between an upper transmission compression roller and a lower transmission compression roller, then the rotating disc is rotated to adjust the distance between the upper transmission compression roller and the lower transmission compression roller, so that the upper transmission compression roller and the lower transmission compression roller are matched in position, then the lower transmission compression roller is driven to rotate through the operation of a transmission motor, so that the paper board moves forwards, meanwhile, the upper transmission compression roller is driven to rotate through the paper board, glue liquid in a gluing groove drips on the upper transmission compression roller through a glue outlet through hole, and the glue liquid is uniformly coated on the paper board through the rotation of the upper transmission compression roller to finish gluing; in the mistake of rubber coating, the width of cardboard is certainly less than the width of last pressure roller, and the play gluey scope of rubberizing groove lower extreme can't be controlled, lead to going up to be covered with glue on the pressure roller, and the glue that lies in the position outside the cardboard scope can not utilized, lead to the waste of glue, secondly, in last gluey in-process, glue falls on last pressure roller through going up between the rubberizing groove, can't guarantee glue evenly distributed on last transmission compression roller, lead to the glue of coating on the cardboard inhomogeneous, glue can not lead to pasting insecurely enough, glue is too much easy to make the cardboard moist to lead to the cardboard to damage easily in the course of working.

Specifically, the second limiting assembly 5b comprises a limiting shaft 5b1, a second limiting plate 5b2 and a speed reducer 5b3, two ends of the limiting shaft 5b1 are rotatably connected with the frame 1, the second limiting plate 5b2 is fixedly connected with the limiting shaft 5b1, the speed reducer 5b3 is installed at one side of the frame 1, an input end of the speed reducer 5b3 is in transmission connection with the first conveying belt 2, and an output end of the speed reducer 5b3 is fixedly connected with one end of the limiting shaft 5b 1; when the first conveyer belt 2 operates, the speed reducer 5b3 drives the limiting shaft 5b1 to rotate, when the front end of the paper board on the first conveyer belt 2 is abutted against the second limiting plate 5b2, the conveying distance between the two paper boards is controlled, and when the limiting shaft 5b1 drives the second limiting plate 5b2 to continue to rotate to the lower side, the paper board on the first conveyer belt 2 is conveyed to the second conveyer belt 3, and the gluing mechanism 4 is used for gluing.
The working principle of the invention is as follows: before using, promote regulating plate 4a3 through electric putter 4a2 work and move in vertical direction, regulating plate 4a3 drives two regulating blocks 4a4 and covers gluey roller 4b2 and removes, thereby adjust and cover the distance between rubber roll 4b2 and the conveying roller 4b1, be convenient for carry the cardboard of different thickness, afterwards, the manual work places the cardboard on first conveyer belt 2, laminate one side and the first limiting plate 5a1 of cardboard, the front end and the conflict of second limiting plate 5b2 of cardboard on the first conveyer belt 2, thereby control the transport distance between two cardboards, when spacing axle 5b1 drives second limiting plate 5b2 and continues to rotate to the below, the cardboard on the first conveyer belt 2 is carried to on second conveyer belt 3, and carry out the rubberizing by rubberizing mechanism 4. When the gluing mechanism 4 works, a glue source is connected with a connector 4c4 on a gluing column 4c1 through a pipeline, so that glue is continuously supplied into a glue containing cavity 4c2, a gluing motor 4b3 works to drive a driving wheel 4b4 to rotate, a glue coating motor 4b3 drives a glue coating roller 4b2 to rotate under the transmission connection of a belt and two driving wheels 4b4, meanwhile, a glue coating roller 4b2 rotates to drive a driving gear 4d4 to rotate, the driving gear 4d4 drives a driving gear 4d4 rack to rotate, the driving gear 4d3 pulls a rotating wheel 4d2 to rotate, the rotating wheel 4d1 drives a gluing column 4c1 to rotate for a certain angle so that a glue seam 4c3 is close to the glue coating roller 4b2 for gluing, after the glue is fully distributed on the glue coating roller 4b2 from a glue outlet seam 4c 7, the glue coating roller 2 rotates to a glue homogenizing plate 4g2, and the glue coating gap between the glue coating roller 3 2 and the glue coating roller 2 is kept by the glue coating roller 2, therefore, the glue applying roller 4b2 is ensured to have uniform glue applying thickness, redundant glue can be accumulated between the even-touch plate 4g2 and the glue-coating roller 4b2, on one hand, the glue applying roller is used for supplementing the place where the glue applying thickness of the glue-coating roller 4b2 is insufficient, on the other hand, the glue flows into the recycling groove after being accumulated excessively and is discharged along the recycling groove, the recycling opening and the discharge plate 4g3, and the uniform glue on the glue-coating roller 4b2 is coated on the upper end of the paperboard through the rotation of the glue- coating roller 4b 2.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
