[0004] The prior art mainly transports cartons through a conveyor belt. In order to ensure that the cartons do not shift, pressing rollers are usually set to press the cartons. The cardboard of the cartons is of a corrugated structure. In the prior art, bolts are mostly used to adjust the positions of the pressing rollers, that is, the positions of the pressing rollers are fixed and form a hard connection. For the unevenness of the cartons, it is difficult for a fixed gap to adapt to the unevenness of the cartons, which will damage the corrugations of the cartons and thus affect the strength of the cartons.

[0005] Therefore, we propose a carton gluing machine for carton production. Content of the Utility Model

[0006] The utility model mainly solves the technical problem that the corrugated structure will be damaged during the process of transporting cartons, thereby affecting the strength, and provides a carton gluing machine for carton production.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions. A carton gluing machine for carton production includes:

[0008] A frame, on the top of the frame, a conveyor belt is provided, and on the top of the frame, a carton gluing structure for applying glue is also provided;

[0010] Adjusting structure, arranged at the top of the frame for adjusting the distance between the pressure roller and the conveyor belt. The adjusting structure includes a vertical plate, an adjusting block, a limiting screw, a spring and a pressing plate. The vertical plate is fixedly connected to the frame. The adjusting block is elastically connected to the vertical plate through the spring. The pressing plate is slidably connected to the vertical plate. The pressing plate can squeeze the spring to adjust the pre-pressure value of the spring. The limiting screw is threadedly connected to the adjusting block, and the limiting screw can limit the downward movement distance of the adjusting block.

[0011] As a preferred embodiment of the present invention, the vertical plate forms a rectangular block structure. The same vertical plates are arranged at both ends of the pressure roller. The same adjusting blocks are slidably connected to the wall surfaces of each vertical plate. The two ends of the pressure roller are respectively rotatably connected to the two adjusting blocks.

[0012] As a preferred embodiment of the present invention, the adjusting structure further includes a side chute. A side chute is opened on one side of the vertical plate. The adjusting block is slidably connected to the side chute.

[0013] As a preferred embodiment of the present invention, the side chute forms a rectangular notch, and the adjusting block is adapted to the side chute.

[0014] As a preferred embodiment of the present invention, the adjusting structure further includes an adjusting bolt and a pressing cover. The pressing cover is detachably connected to the vertical plate. The adjusting bolt is threadedly connected to the pressing cover. The lower end surface of the adjusting bolt can abut against the pressing plate and push the pressing plate to slide.

[0015] As a preferred embodiment of the present invention, the pressing cover forms a plate-like structure with the same cross-section as the vertical plate. The pressing cover is locked and fixed to the vertical plate through bolts. A threaded hole is opened on the wall surface of the pressing cover. The adjusting bolt is threadedly connected to the threaded hole of the pressing cover.

[0016] As a preferred embodiment of the present invention, the spring is located between the pressing plate and the adjusting block. The pressing plate is adapted to the side chute and is slidably connected to the side chute.

[0017] The present invention provides a carton gluing machine for carton production. It has the following beneficial effects:

[0018] 1. For a carton gluing machine used in carton production, by rotating the limit screw, the lower end face of the limit screw abuts against the inner bottom surface of the vertical plate, thereby limiting the maximum distance of the adjustment block from moving downward, and the distance between the pressure roller and the conveyor belt is fixed. On the basis of ensuring the limitation of the carton, the pressure roller can avoid damaging the corrugated structure of the cardboard due to too small a distance between the pressure roller and the conveyor belt. The spring can be fixedly connected to the top of the adjustment block, and the adjustment block is pushed by the spring to slide along the vertical plate, realizing the elastic connection of the adjustment block. Then, the distance between the pressure roller and the conveyor belt can be automatically adjusted within a certain range, which has stronger adaptability to cartons of different thicknesses and is beneficial to actual production. Of course, the limit screw can also be rotated so that the lower end face of the limit screw is flush with the bottom of the adjustment block, and then the adjustment block can be elastically connected to the vertical plate by the thrust of the spring. At this time, the downward movement distance of the adjustment block is not limited by the limit screw.

[0019] 2. For a carton gluing machine used in carton production, by rotating the adjustment bolt, the adjustment bolt pushes the pressure plate to slide downward in the side chute and squeeze the spring, realizing the adjustment of the elastic force value of the spring. Then, the thrust of the spring on the adjustment block can be adjusted, and the downward pressure of the pressure roller on the carton can be adjusted within a certain range, with strong adjustability and higher adaptability.

[0026] A carton gluing machine used in carton production, as Figure 1 and Figure 2 shown, includes:

[0027] The frame 10 is provided with a conveyor belt at the top. The top of the frame 10 is also provided with a carton gluing structure 11 for applying glue. Specifically, the carton gluing structure 11 includes a housing. A blower is installed at the top of the housing, and a glue applicator nozzle is installed on the inner top surface of the housing. Through the glue applicator nozzle, glue is applied to the position where the carton needs to be bonded to achieve the adhesion of the carton. This is the existing well-known technology and will not be elaborated here.

[0028] The pressing roller 12 is arranged above the conveyor belt for pressing the carton. Specifically, the pressing roller 12 is of a cylindrical structure. The carton is limited by the pressing roller 12 to prevent the offset of the carton, thereby ensuring the accuracy of adhesion.

[0029] Such as Figure 1 、 Figure 3 、 Figure 4 And Figure 5 As shown in

[0030] Such as Figure 3As shown in the figure, the adjusting structure further includes a side sliding groove 27. A side sliding groove 27 is formed on one side of the vertical plate 20. The adjusting block 21 is slidably connected to the side sliding groove 27. The side sliding groove 27 forms a rectangular notch. The adjusting block 21 is adapted to the side sliding groove 27. The spring 23 is located between the pressing plate 24 and the adjusting block 21. The pressing plate 24 is adapted to the side sliding groove 27 and is slidably connected to the side sliding groove 27. The pressing plate 24 and the adjusting block 21 are limited by the side sliding groove 27, so that the pressing plate 24 and the adjusting block 21 can maintain vertical sliding, and thus the pressure roller 12 is more stable and not easily offset when adjusting the position.

[0031] As Figure 3 shown in the figure, the adjusting structure further includes an adjusting bolt 25 and a gland 26. The gland 26 is detachably connected to the vertical plate 20. The adjusting bolt 25 is threadedly connected to the gland 26. The lower end surface of the adjusting bolt 25 can abut against the pressing plate 24 and push the pressing plate 24 to slide. The gland 26 forms a plate-like structure with the same cross-section as the vertical plate 20. The gland 26 is locked and fixed to the vertical plate 20 by bolts. A threaded hole is formed on the wall surface of the gland 26. The adjusting bolt 25 is threadedly connected to the threaded hole of the gland 26. As a supplementary description of the above solution, by rotating the adjusting bolt 25, the adjusting bolt 25 pushes the pressing plate 24 to slide down in the side sliding groove 27 and squeezes the spring 23, so as to adjust the elastic force value of the spring 23. Then the thrust of the spring 23 on the adjusting block 21 can be adjusted, and the downward pressure of the pressure roller 12 on the carton can be adjusted within a certain range, with strong adjustability and higher adaptability.

[0032] The working principle of the present utility model: Rotate the limit screw 22. The lower end surface of the limit screw 22 abuts against the inner bottom surface of the vertical plate 20, thereby limiting the maximum distance of the downward movement of the adjusting block 21, and the distance between the pressure roller 12 and the conveyor belt is fixed. It is also possible to rotate the limit screw 22 so that the lower end surface of the limit screw 22 is flush with the bottom of the adjusting block 21. Then the adjusting block 21 can be elastically connected to the vertical plate 20 by means of the thrust of the spring 23. At this time, the downward movement distance of the adjusting block 21 is not limited by the limit screw 22. Rotate the adjusting bolt 25. The adjusting bolt 25 pushes the pressing plate 24 to slide down in the side sliding groove 27 and squeezes the spring 23, so as to adjust the elastic force value of the spring 23. Then the thrust of the spring 23 on the adjusting block 21 can be adjusted. The adjusting block 21 is elastically connected by pushing the adjusting block 21 to slide along the vertical plate 20 through the spring 23, and the distance between the pressure roller 12 and the conveyor belt can be automatically adjusted within a certain range to adapt to cartons of different thicknesses.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
