[0030] Embodiment 1:

[0031] like Figures 1 to 7As shown, the utility model provides a carton board adhesion glue brushing mechanism, including a first conveyor belt 1; the first conveyor belt 1 is used to convey the carton board 8; the number of the glue brushing mechanisms is selected according to the needs, when the number of the glue brushing mechanisms is multiple, it is necessary to ensure that the positional relationship between the multiple glue brushing mechanisms is parallel to each other, the glue brushing mechanism includes a frame 2, a glue storage box 3 and a second conveyor belt 4; the first conveyor belt 1 and the second conveyor belt 4 can be conveyor belt conveyors in the prior art; the frame 2 is an inverted U-shaped frame 2 structure; the frame 2 is fixed on the fixing frame 5 of the first conveyor belt 1, or the frame 2 is fixed to the ground by bolts, as long as the first conveyor belt 1 is ensured and the second conveyor belt 4 are parallel to each other; the glue storage box 3 is fixed to the bottom side of the frame 2 by bolts, and the glue storage box 3 is located above the first conveyor belt 1; glue is stored in the glue storage box 3; a glue outlet 24 is opened at the lower end of the glue storage box 3; the second conveyor belt 4 is arranged between the glue outlet 24 and the first conveyor belt 1; the second conveyor belt 4 is connected to the lower end of the glue storage box 3, and the second conveyor belt 4 corresponds to the glue outlet 24; the second conveyor belt 4 is located above the first conveyor belt 1, and the lower end of the second conveyor belt 4 is used to fit with the upper end surface 8 of the carton board; wherein, the transmission direction of the second conveyor belt 4 is opposite to the transmission direction of the first conveyor belt 1.

[0032] The conveying rollers 7 on the first conveyor belt 1 and the second conveyor belt 4 are driven to rotate by their respective servo motors 6. The rotation directions of the two servo motors 6 are opposite, so that the first conveyor belt 1 and the second conveyor belt 4 jointly convey the carton board 8. The rotation of the conveying rollers 7 can be accurately controlled by the servo motor 6, so that continuous and stable transportation can be achieved, so that the carton board 8 is conveyed from one side of the second conveyor belt 4 to the other side. During the movement of the carton board 8, the glue stored in the glue storage box 3 can fall onto the second conveyor belt 4 through the glue outlet 24. Under the action of the second conveyor belt 4, the glue can adhere to the upper side of the carton board 8, and under the action of the first conveyor belt 1, the carton board 8 with glue attached can leave the second conveyor belt 4, completing the gluing of the carton board 8.

[0033] In the present application, the first conveyor belt 1 and the second conveyor belt 4 can jointly convey the carton board 8, and can realize continuous and stable transportation.

At the same time, since the glue automatically falls onto the conveyor belt through the glue outlet 24, the amount of glue and the uniformity of coating can be ensured, avoiding the waste and uneven coating that may occur during manual gluing.

[0034] Embodiment 2:

[0035] In this embodiment, on the basis of the first embodiment, the second conveyor belt 4 includes two fixed plates 9, a winding belt 10 and a rotating member 11. The second conveyor belt 4 is different from the conveyor belt conveyor structure in the prior art. Specifically, the two fixed plates 9 are symmetrically fixedly connected to the two sides of the lower end of the glue storage box 3, and the fixed plates 9 extend downward to the bottom of the glue storage box 3; the fixed plates 9 are arranged along the conveying direction of the second conveyor belt 4;

[0036] The rotating member 11 includes more than two rotating rollers; the opposite side walls of the two fixed plates 9 are provided with horizontal rotating holes; the two ends of the rotating rollers are rotatably connected in the corresponding rotating holes through bearings; the rotating rollers are evenly arranged along the conveying direction of the first conveyor belt 1; the winding belt 10 is wound around the rotating rollers; the winding belt 10 is located between the glue outlet 24 and the first conveyor belt 1, and the winding belt 10 is used to fit with the upper end surface of the carton board 8, the servo motor 6 in the second conveyor belt 4 is fixedly connected to the fixed plate 9 therein, and the power end of the servo motor 6 is rotatably extended into the fixed plate 9 and is coaxially fixedly connected with one end of one of the rotating rollers;

[0037] It should be noted that the number of rotating rollers is selected according to needs. At the same time, the shape formed by the wrapping tape 10 wrapped around the rotating roller can also be square, diamond, etc.; just ensure that one side of the wrapping tape 10 is located below the glue outlet 24; and the other side of the wrapping tape 10 is located on the first conveyor belt 1, so that the upper side of the carton board 8 can contact this side, so that it can be ensured that the glue can fall from the glue outlet 24 onto the wrapping tape 10 below, and when the rotating roller is driven to rotate by the servo motor 6, the wrapping tape 10 can thereby transport the glue to the upper side of the carton board 8, thereby completing the gluing.

[0038] Specifically, the number of rotating rollers is four; the winding belt 10 is wound on the four rotating rollers, so that the shape of the winding belt 10 is an isosceles trapezoid; the upper side of the winding belt 10 is arranged horizontally and is located below the glue outlet 24; the lower side of the winding belt 10 is arranged horizontally and is located above the first conveyor belt 1; a pressing piece 12 is provided on the inner side of the winding belt 10; by providing four rotating rollers and making the shape of the winding belt 10 isosceles trapezoid, sufficient space can be left on the inner side of the winding belt 10, and compared with providing two rotating rollers, this space is larger and can accommodate more pressing pieces 12;

[0039] A plurality of pressing members 12 are evenly arranged in the direction from one end of the fixed plate 9 to the other end of the fixed plate 9; the pressing member 12 includes a rotating shaft 13, a torsion spring 14 and a clamping block 15; horizontal fixing holes are opened on the two fixing plates 9; both ends of the rotating shaft 13 are rotatably connected in the corresponding fixing holes; the torsion spring 14 is sleeved on the rotating shaft 13; one end of the torsion spring 14 is fixedly connected to the clamping block 15, and the other end of the torsion spring 14 is fixedly connected to the fixing plate 9; the clamping block 15 is fixedly sleeved on the rotating shaft 13; the clamping block 15 is arranged obliquely; the end of the clamping block 15 away from the rotating shaft 13 is the horizontal side; the horizontal side is tightly pressed against the side of the winding belt 10 away from the first conveyor belt 1; under the action of the torsion spring 14, the rotating shaft 13 can be driven to rotate in the fixed hole, so that the rotating shaft 13 drives the clamping block 15 to rotate, so that the horizontal side of the clamping block 15 can press the winding belt 10 downward;

[0040] In this way, when conveying the carton board 8, the carton board 8 will pass through the first conveyor belt 1 and fit tightly against the wrapping belt 10 above. Through the action of the torsion spring 14, the clamping block 15 will press the wrapping belt 10, further increasing the contact tightness between the wrapping belt 10 and the carton board 8. This can effectively increase the contact area between the glue and the top side of the carton board 8, ensuring that the glue is more fully applied to the upper side of the carton board 8, so that the glue can be effectively used, thereby optimizing the gluing effect.

[0041] In this embodiment, rollers 16 are disposed on both sides of the lower end of the pressing block 15 ; the lower ends of the rollers 16 abut against the winding belt 10 .

[0042] The setting of the roller 16 replaces the sliding contact between the clamping block 15 and the inner side of the winding belt 10. When the winding belt 10 is conveying glue, the roller 16 and the inner side of the winding belt 10 are in rolling contact, which can reduce friction and reduce the wear of the winding belt 10, thereby extending the service life of the winding belt 10.

[0045] By controlling the extension or shortening of the telescopic end of the telescopic member 17, the height of the glue storage box 3 can be controlled, thereby controlling the distance between the second conveyor belt 4 and the first conveyor belt 1, so that when conveying carton boards 8 of different thicknesses, it is ensured that the glue can be applied to the top side of the carton board 8 through the second conveyor belt 4, that is, no matter how the thickness of the carton board 8 changes, the glue can be applied to the carton board 8, which has high flexibility.

[0046] Embodiment 4:

[0048] Specifically, four corners of the cover plate 21 are respectively provided with vertical through holes; corners of the top of the glue storage box 20 are provided with vertical through slots; each through hole is coaxial with the corresponding through slot; by using screws 22 to pass through the through holes and be threadedly connected in the corresponding through slots, the cover plate 21 and the glue storage box 20 can be detachably connected;

[0049] The bottom plate 19 fixedly connected to the telescopic end of the telescopic member 17 is bolted to the cover plate 21 .

[0050] By setting the cover plate 21 and the glue storage box 20 to be detachably connected, the cover plate 21 can be removed by unscrewing the screws 22, so that it is convenient to clean the dried glue adhering to the inner wall of the glue storage box 20.

[0052] The snap-on design of the top cover ensures the sealing of the glue adding port to prevent dust or debris from entering. The existence of the lifting plate 23 allows the operator to easily open the top cover for convenient glue adding or cleaning work, and at the same time, the lifting plate 23 contacts the top side of the cover body, which can prevent the top cover from falling into the glue storage box 20.

[0053] In this embodiment, the glue outlet 24 is opened at one end of the bottom of the glue storage box 20; the shape of the glue outlet 24 can be square or round, as long as it is ensured that the glue can drip onto the second conveyor belt 4 through the glue outlet 24; the glue outlet 24 is arranged close to one end of the glue storage box 20; a solenoid valve 25 located below the glue outlet 24 is fixed to the bottom side of the glue storage box 20, and the solenoid valve 25 can adopt a straight-through solenoid valve 25.
