DETAILED DESCRIPTION

[0020] The following will be combined with the attached embodiment of the utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As shown in the figure, a gluing mechanism of a box gluer includes a frame 1, on which a glue gun 2, a smoothing assembly 3 and a press edge assembly 4 are arranged, and a supporting plate 11 located below the glue gun 2 is arranged on the frame 1, and the smoothing assembly 3 includes a smoothing plate 31 arranged on the frame 1 at one side of the glue gun 2, the plate surface of the smoothing plate 31 is perpendicular to the feeding direction of the box gluer, and a smoothing gap 12 is formed between the lower end of the smoothing plate 31 and the supporting plate 11, and the press edge assembly 4 includes a mounting plate 41 and a press edge wheel 42, the mounting plate 41 is fixedly connected to the supporting plate 11, and a plurality of the press edge wheels 42 are rotatably arranged on the mounting plate 41 at intervals along the feeding direction of the box gluer.

[0022] In the above embodiment, the cardboard is transported along the conveyor belt on the box gluer into the space between the glue gun 2 and the supporting plate 11 and is bonded to the supporting plate 11. The conveyor belt for conveying the cardboard is generally arranged on the inner side of the frame 1, and two belts are arranged above and below to cooperate with the clamping cardboard to realize the conveying of the cardboard. This part of the structure for realizing the cardboard conveying is the prior art and will not be described in detail here. The side end of the cardboard that is bonded to the supporting plate 11 and continues to be transported forward enters between the pressing wheel 42 and the supporting plate 11. The side end of the cardboard is affected by the pressing wheel 42, so that the side end of the cardboard that needs to be glued passes under the glue gun 2 and the trowel plate 31 to keep it flat, thereby improving the accuracy of the glue gun 2 spraying glue on the cardboard. After the glue gun 2 sprays the glue on the cardboard, the cardboard continues to be transported forward and passes through the smoothing gap 12. The lower end of the trowel plate 31 evenly spreads the glue sprayed on the cardboard, so that the glue is more evenly attached to the cardboard, thereby ensuring the quality of the finished paper box after subsequent production.

[0023] Furthermore, an upright linear slide rail 13 is fixedly provided on the frame 1, a sliding seat 14 is slidably provided on the linear slide rail 13, the glue gun 2 is fixedly provided on the sliding seat 14, an adjusting screw 15 threaded in the sliding seat 14 is rotatably provided on the frame 1, the smoothing assembly 3 also includes a support plate 32, the support plate 32 is fixedly connected to the sliding seat 14, and the smoothing plate 31 is provided on the support plate 32.

[0024] Specifically, the driving structure of the adjusting screw 15: a height sensor 16 located between the glue gun 2 and the trowel plate 31 is fixedly provided on the support plate 32, an adjusting motor 17 transmission-connected to the adjusting screw 15 is provided on the frame 1, and the adjusting motor 17 cooperates with the height sensor 16 through a controller.

[0025] In the above preferred embodiment, the sliding seat 14 can be driven to slide on the linear slide rail 13 by rotating the adjusting screw 15 to adjust the height of the glue gun 2 and the trowel plate 31 to adapt to the gluing operation of cardboards of different thicknesses, so that the gluing mechanism has better applicability. Preferably, the rotation of the adjusting screw 15 is driven by the adjusting motor 17. When the cardboard passes under the height sensor 16, the sensor will obtain the thickness of the cardboard and control the adjusting motor 17 through the controller to drive the adjusting screw 15 to rotate to achieve height adjustment of the glue gun 2 and the trowel plate 31, so that the adjustment process is automated and more precise.

[0026] Furthermore, the smoothing assembly 3 also includes a mounting arm 33, and two adjusting waist holes 321 parallel to the feeding direction of the folder gluer are formed on the support plate 32. Two connecting rods 331 matching the adjusting waist holes 321 and passing through the two adjusting waist holes 321 upward are formed on the mounting arm 33. A connecting nut 34 tightly pressed against the support plate 32 is screwed on the connecting rod 331, and the smoothing plate 31 is arranged on the mounting arm 33.

[0027] In the above preferred embodiment, the link nut is loosened so that the connecting rod 331 can slide on the adjusting waist hole 321 to adjust the position of the mounting arm 33 on the support plate 32, that is, to adjust the distance of the trowel plate 31 relative to the glue gun 2, so that the distance between the trowel plate 31 and the glue gun 2 can be adapted to cardboards of different widths, so that after the glue gun 2 sprays glue on the cardboard, the trowel plate 31 will evenly spread the glue, thereby ensuring the smoothing effect and making the gluing mechanism have better applicability.

[0028] Preferably, the cross-section of the trowel plate 31 is T-shaped, and a mounting groove 332 is provided in the mounting arm 33, which matches the large end of the trowel plate 31 and passes through the mounting arm 33 to one end. The large end of the trowel plate 31 is inserted into the mounting groove 332, and a fixing plate 333 is fixedly connected to the notch of the mounting groove 332 by bolts. A clearance notch 411 is provided on the mounting plate 41 for the trowel plate 31 to pass through. In the installation structure of the above-mentioned trowel plate 31, after the bolts are unscrewed and the fixing plate 333 is removed, the trowel plate 31 can be slid out of the mounting groove 332 and taken out through the clearance notch 411, which facilitates the disassembly and assembly of the trowel plate 31, thereby facilitating the cleaning or replacement of the trowel plate 31.

[0029] Preferably, the trowel plate 31 is made of polytetrafluoroethylene and the lower end of the trowel plate 31 is arc-shaped. Due to the non-stick property of polytetrafluoroethylene, the probability of glue adhering to the trowel plate 31 when smoothing the glue is reduced, which ensures the smoothing effect and extends the service life of the trowel plate 31.

[0030] Preferably, the edge pressing assembly 4 also includes a wheel seat 43, a telescopic rod 44 and a spring 45, the edge pressing wheel 42 is rotatably set on the wheel seat 43, at least two of the telescopic rods 44 are fixedly connected to the wheel seat 43 and pass upward through the mounting plate 41, the spring 45 is sleeved on the telescopic rod 44 and is located between the wheel seat 43 and the mounting plate 41, the edge pressing wheel 42 is pressed against the supporting plate 11 under the action of the spring 45, when the side end of the cardboard enters between the edge pressing wheel 42 and the supporting plate 11, the edge pressing wheel 42 is tightly pressed against the cardboard under the action of the spring 45 to achieve a better edge pressing effect, so that the cardboard can be better kept flat when passing under the glue gun 2 and the trowel plate 31, and when cardboards of different thicknesses enter between the edge pressing wheel 42 and the supporting plate 11, the telescopic rod 44 slides on the mounting plate 41 so that the edge pressing wheel 42 can be suitable for the edge pressing of cardboards of different thicknesses, so that the gluing mechanism has better applicability.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
