Description

Technical Field

[0001] The utility model belongs to the technical field of gluing, and in particular relates to a paper box gluing device. Background Art

[0002] The paper box has a three-dimensional structure and is usually formed by folding a die-cut paper box board. In order to keep the structure of the paper box stable, glue needs to be applied to the joints of the paper box. Therefore, a gluing device is needed to glue the paper box board.

[0003] A Chinese patent with publication number CN206551554U discloses a carton gluing device, which includes a hydraulic cylinder, a gluing roller and a pressure roller. The device allows the carton board to pass between the gluing roller and the pressure roller, applies glue to the surface of the carton board, and completes the gluing work on the carton board.

[0004] Among them, when applying glue, the glue application position is usually close to the end edge of the carton board. When assembling the carton, the two ends of the carton board need to be glued together by glue, and the bonding position is squeezed. During the squeezing process, the glue will overflow and diffuse. When the above scheme is used, since the glue roller is in continuous contact with the carton board, the glue is continuously distributed on the surface of the carton board. When assembling the carton, the glue on the carton board is easily squeezed and overflowed, which not only wastes the glue but also easily causes the glue to adhere to the work surface, which is inconvenient to clean. Utility Model Content

[0005] The utility model aims to provide a paper box gluing device to solve the problem in the prior art that glue liquid easily overflows due to squeezing when assembling paper boxes.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A paper box gluing device comprises a workbench, a gluing roller and a glue supply assembly, wherein a conveying mechanism is arranged on the top of the workbench, and a plurality of paper box plates are placed in sequence on the top of the conveying mechanism along the left-right direction, a second motor is fixedly arranged on one side of the workbench, the gluing roller is arranged above the workbench along the front-back direction, the gluing roller can rotate relative to the workbench, a plurality of brush heads are arranged at intervals in the circumferential direction on the outer edge of the gluing roller, the second motor can drive the gluing roller to rotate through a transmission mechanism, the glue supply assembly is fixedly arranged above the workbench, and the glue supply assembly is used to attach glue liquid to the brush head.

[0008] The principle and effect of this technical solution:

[0009] Start the second motor to drive the glue coating roller to rotate, so that the brush head on the glue coating roller adheres to the glue from the glue supply assembly. At this time, the conveying mechanism rotates, driving the carton plate to pass through the glue coating roller, and making the carton plate contact with the brush head of the glue coating roller. The brush heads arranged at intervals apply glue at intervals on the top of the carton plate.

[0010] Through the above arrangement, the glue on the top of the carton board is in the form of lines distributed at intervals. When assembling the carton, when the glue is squeezed, it will flow to the blank space between two adjacent lines of glue, so that the glue can fully cover the carton board and make it difficult for the glue to overflow from the carton board, thereby solving the problem that the glue is easy to overflow due to squeezing when assembling the carton.

[0011] In the utility model, an induction part is fixedly arranged on the top of the workbench, and a first mounting frame is also arranged on the top of the workbench, a mounting plate is horizontally arranged in the first mounting frame, and a reciprocating shaft is respectively slidably penetrated by the left and right ends of the mounting plate along the vertical direction, and the two ends of the glue coating roller are respectively rotatably inserted into the two reciprocating shafts, a fixed plate is arranged on the outer periphery of the reciprocating shaft below the mounting plate, a first tension spring is sleeved between the fixed plate and the mounting plate outside the reciprocating shaft, a rotating shaft is rotatably inserted on the first mounting frame above the mounting plate, and eccentric wheels are fixedly sleeved outside the rotating shaft just above the reciprocating shaft, the top of the reciprocating shaft abuts against the eccentric wheel, a first motor is fixedly arranged on the side wall of the first mounting frame, and the output shaft of the first motor is fixedly connected to the rotating shaft.

[0012] The principle and effect of this technical solution:

[0013] The carton plate is carried by the conveying mechanism and moves toward the glue coating roller. When the sensing component detects that a carton plate has passed by, the first motor drives the rotating shaft to rotate 180°, so that the eccentric wheel moves to the lowest position from the farthest point of the rotating shaft. The eccentric wheel pushes the reciprocating shaft to move to the lowest point. At this time, the brush head can adhere to the glue from the glue supply component. When the sensing component detects that the carton plate has completely passed through the sensing component, the first motor drives the rotating shaft to rotate 180° again, so that the eccentric wheel moves to the highest position from the farthest point of the rotating shaft. The reciprocating shaft moves upward under the action of the first tension spring and keeps in contact with the eccentric wheel. At this time, the brush head cannot adhere to the glue from the glue supply component.

[0014] The above arrangement can prevent the brush head from continuously adhering glue from the glue supply assembly when there is no carton board on the conveying mechanism, causing the glue to accumulate on the brush head, resulting in the glue falling on the surface of the conveying mechanism, or causing the glue to not be evenly applied to the surface of the carton board.

[0015] In the utility model, a second mounting frame is fixedly provided on the top of the workbench, and the glue supply assembly includes a glue box and a glue supply roller. The glue box is fixedly provided on the top of the second mounting frame, and the glue supply roller is rotatably inserted into the second mounting frame along the front-rear direction. A glue absorption layer is fixedly provided on the outer periphery of the glue supply roller, and the glue supply roller is located below the glue box, and the glue absorption layer can absorb glue liquid from the glue box.

[0016] In the utility model, a slide groove is provided on one side of the second mounting frame, a slider is slidably embedded in the slide groove, a second tension spring is provided between the slider and the inner wall of the slide groove, one end of the glue supply roller is fixedly connected to the output shaft of the second motor, and the transmission mechanism includes a first pulley rotatably arranged on one side of the slider, a second pulley fixedly arranged at the other end of the glue supply roller, and a third pulley fixedly arranged at one end of the glue coating roller, and a transmission belt is wound around the first pulley, the second pulley and the third pulley.

[0017] The principle and effect of this technical solution:

[0018] When the reciprocating shaft reciprocates vertically, the distance between the second pulley and the third pulley changes accordingly. When the distance between the second pulley and the third pulley shortens, the second tension spring drives the slider to move away from the second pulley, so that the transmission belt maintains tension.

[0019] Through the above arrangement, it is possible to avoid the loosening of the conveyor belt due to the change in the spacing between the second pulley and the third pulley, thereby preventing the transmission efficiency from being low, thereby ensuring the stability of the transmission process.

[0020] In the utility model, a scraper is fixedly arranged in the second mounting frame along the front-to-back direction, the scraper is located below the glue supply roller, and the scraper abuts against the glue absorption layer of the glue supply roller, and a collection box is fixedly arranged below the scraper. When the brush head does not adhere to the glue from the glue absorption layer, the scraper scrapes off the excess glue from the glue absorption layer, and the glue that is hung off is collected in the collection box. Through the above arrangement, the excess glue can be collected to prevent the glue on the glue absorption layer from falling onto the surface of the conveying mechanism.

[0021] In the present invention, the glue supply assembly further comprises a pump body, which is fixedly arranged on the side wall of the second mounting frame, and the glue box, the pump body and the collection box are connected via a reflux pipe. Through the above arrangement, the glue in the collection box can be reused, thereby achieving the effect of saving glue resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, a second mounting frame 16 is fixedly provided on the top of the workbench 10, and the glue supply assembly 30 includes a glue box 31 and a glue supply roller 32. The glue box 31 is fixedly provided on the top of the second mounting frame 16, and the glue supply roller 32 is rotatably inserted into the second mounting frame 16 along the front-to-back direction.

[0034] The specific implementation process is as follows:

[0035] The second motor 161 is started to drive the glue coating roller 20 to rotate, so that the brush head 21 on the glue coating roller 20 adheres to the glue from the glue supply assembly 30. At this time, the conveying mechanism 11 rotates, driving the carton plate 12 to pass through the glue coating roller 20, and the carton plate 12 contacts the brush head 21 of the glue coating roller 20. The brush heads 21 arranged at intervals apply glue at intervals on the top of the carton plate 12.

[0036] The carton plate 12 is carried by the conveying mechanism 11 and moves in the direction close to the glue coating roller 20. When the sensing element 13 detects that the carton plate 12 passes by, the sensing element 13 converts the physical change into an electrical signal, and the signal processing module transmits the instruction to the first motor 144. The first motor 144 drives the rotating shaft 142 to rotate 180°, so that the eccentric wheel 143 moves to the lowest position from the farthest point of the rotating shaft 142.

When the sensing element 13 detects that the carton plate 12 has completely passed through the sensing element 13, the first motor 144 drives the rotating shaft 142 to rotate 180° again, so that the eccentric wheel 143 moves to the highest position from the farthest point of the rotating shaft 142. The reciprocating shaft 15 moves upward under the action of the first tension spring 152 and keeps in contact with the eccentric wheel 143. At this time, the brush head 21 cannot adhere to the glue from the glue supply component 30.

[0037] When the reciprocating shaft 15 reciprocates vertically, the distance between the second pulley 322 and the third pulley 22 changes accordingly. When the distance between the second pulley 322 and the third pulley 22 becomes shorter, the second tension spring 164 drives the slider 163 to move away from the second pulley 322, so that the transmission belt 40 maintains tension.
