[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the automatic gluing device in this embodiment, including a base 1, a guide roller 2 and a pressure roller 3. The pressure roller 3 is rotatably installed in the base 1, and two groups of pressure rollers 3 are provided. A plurality of groups of guide rollers 2 for paper limiting conveying are provided on the side of the base 1. A moving part 4 is installed on the side of the base 1, and a spraying mechanism 5 for stable gluing of the paper is installed on one side of the end of the moving part 4.

[0030] During use, the subsequent stacked and bonded papers are limited and conveyed by the guide roller 2, and multiple groups of papers are concentrated between the pressure rollers 3. During the conveying process, the spraying mechanism 5 is operated to spray a proper amount of glue on the surface of the papers. During the spraying process of the spraying mechanism 5, the moving part 4 can flexibly adjust the position of the spraying mechanism 5 itself to ensure that the glue on the surface of the papers can stably bond the papers. After the glue is sprayed, the pressure roller 3 presses the papers to assist in bonding and strengthen the connection between the papers. The gluing process of the papers is preliminarily completed, the automatic gluing operation is realized, and the overall working quality of the equipment is improved.

[0031] By the attached Figure 4 As shown, it is a structural schematic diagram of the spraying mechanism 5 in this embodiment, the spraying mechanism 5 includes a support frame 51, a side connecting plate 52, a glue nozzle 53 and a delivery pipe 54, the support frame 51 is installed at the end of the moving part 4, the side connecting plate 52 is installed at the end of the support frame 51, the glue nozzle 53 is installed at the top of the side connecting plate 52, and the delivery pipe 54 is installed at the top of the glue nozzle 53.

[0032] During use, as the movable part 4 moves, the glue nozzle 53 slides stably on the surface of the paper, and the end of the delivery tube 54 is connected to the pump body and the glue box. The glue inside the glue box passes through the pump body through the delivery tube 54 and enters the glue nozzle 53. The glue nozzle 53 sprays the surface of the paper stably, which facilitates the stacking and bonding of multiple groups of paper. The number of the support frame 51 and the side parts of the support frame 51 is related to the number of papers to be spliced.

[0033] By the attached Figure 4 As shown, it is a structural schematic diagram of the spraying mechanism 5 in this embodiment, and the spraying mechanism 5 also includes a fixed plate 55 and a cleaning brush 56. The fixed plate 55 is installed on the side of the glue nozzle 53. There are two groups of cleaning brushes 56, one group of cleaning brushes 56 is installed at the bottom end of the fixed plate 55, and the other group of cleaning brushes 56 is installed at the bottom end of the side connecting plate 52.

[0034] During use, when the glue nozzle 53 is spraying glue, the moving part 4 will drive the glue nozzle 53 to move, so that the glue nozzle 53 can evenly spray the paper. During the movement of the support frame 51 and the side parts, the cleaning brush 56 will fit the surface of the paper to evenly spread the glue on the surface of the paper. There are two groups of cleaning brushes 56, which follow the moving direction of the glue nozzle 53. The corresponding cleaning brushes 56 can also clean the impurities on the surface of the paper to ensure the quality of the subsequent cardboard bonding.

[0035] By the attached Figure 4As shown, the support frame 51 is composed of a telescopic rod and a telescopic cylinder. The telescopic cylinder is installed on the side of the moving part 4, the telescopic rod is installed in the telescopic cylinder, and the end of the telescopic rod is connected to the side connecting plate 52. During use, the telescopic rod slides stably inside the telescopic cylinder. When the spraying mechanism 5 is used as a whole, the overall length of the support frame 51 can be adjusted according to the width of the paper itself, so as to be suitable for spraying operations on papers of various specifications.

[0036] By the attached Figure 3 As shown, it is a schematic diagram of the structure of the moving part 4 in this embodiment, the moving part 4 includes a moving cross plate 41, a connecting bracket 42 and an electric push rod 43, the electric push rod 43 is installed on the side of the base 1, the connecting bracket 42 is installed on the output end of the moving cross plate 41, and the moving cross plate 41 is installed on the top of the connecting bracket 42.

[0037] During use, as the electric push rod 43 is started, the output end of the electric push rod 43 drives the connecting bracket 42 to move in parallel. At this time, the movable cross plate 41 drives the spraying mechanism 5 to move, which is used to flexibly adjust the position of the glue nozzle 53 during the process of glue spraying by the glue nozzle 53, and can also assist the cleaning brush 56 to clean and smooth the surface.

[0038] By the attached Figure 5 As shown, it is a structural schematic diagram of the extrusion mechanism 6 in this embodiment, and the extrusion mechanism 6 includes a concave plate 62, a swing assembly 63 and an extrusion roller 64. The concave plate 62 is arranged on the side of the movable horizontal plate 41, the swing assembly 63 is installed inside the concave plate 62, and the extrusion roller 64 is installed on the side of the swing assembly 63.

[0039] During use, multiple layers of paper are squeezed by the pressing roller 3 to initially form a cardboard. At this time, the squeezing roller 64 will move in contact with the upper and lower surfaces of the initially formed cardboard to further push and smooth the glue inside the cardboard to prevent part of the glue from accumulating in one place and forming bulges on the surface of the cardboard. The excess glue will be squeezed and pushed by the squeezing roller 64 and pushed out from both sides of the cardboard, which is convenient for the subsequent stable collection of the excess glue.

[0040] By the attached Figure 5 As shown, it is a structural schematic diagram of the extrusion mechanism 6 in this embodiment, and the extrusion mechanism 6 also includes a connecting frame 61 and a supporting frame 65. The supporting frame 65 is installed on one side of the end of the movable horizontal plate 41, and the connecting frame 61 is symmetrically fixedly installed on the side of the supporting frame 65.

[0041] During use, the connecting frame 61 is installed at the other end of the movable horizontal plate 41. When the movable horizontal plate 41 pushes the spraying mechanism 5 to spray evenly, the connecting frame 61 will also drive the squeezing rollers 64 to move stably on the surface of the paperboard. The connecting frame 61 is provided with two groups connected by the supporting frame 65, so that the two groups of squeezing rollers 64 can perform synchronous squeezing operations on the upper and lower surfaces of the paperboard to ensure the working quality of the equipment itself.

[0042] By the attached Figure 6 As shown, the swing assembly 63 includes a fixed base plate 631, a rotating rod 632, a swing arm 633 and a torsion spring 634.

[0043] During use, the torsion spring 634 is installed, and the torsion spring 634 will push the rotating rod 632 and the swing arm 633 to tilt toward the side close to the cardboard, ensuring that the squeezing roller 64 can be close to the surface of the cardboard when moving, and a blocking plate that limits the maximum swing angle of the swing arm 633 is installed at the end of the concave plate 62 to assist the two sets of squeezing rollers 64 to stably fit the surface of the cardboard.

[0044] By the attached Figure 7 As shown, the automatic gluing device also includes a collecting mechanism 7, which includes a bottom shell 71, a moving component 72, a moving bracket 73 and a cleaning scraper 74. The bottom shell 71 is installed on the side of the base 1 opposite to the spraying mechanism 5, the moving component 72 is installed inside the bottom shell 71, the moving bracket 73 is symmetrically installed on the top of the moving component 72, and the cleaning scraper 74 is installed on the side of the moving bracket 73. The cleaning scraper 74 slides along the side wall of the paper.

[0045] During use, the distance between the two groups of movable brackets 73 is adjusted through the operation of the movable assembly 72 itself, so that the cleaning scraper 74 fits on both sides of the cardboard, and the glue squeezed out on both sides of the cardboard is cleaned, so as to facilitate the recovery of excess glue. The movable assembly 72 as a whole is composed of a motor, a bidirectional screw rod, a guide rod and a movable end. The bidirectional screw rod is driven by the motor to rotate inside the bottom shell 71, and the two groups of movable ends move stably along the surface of the bidirectional screw rod to achieve the purpose of adjusting the position of the two groups of movable brackets 73.

[0046] By the attached Figure 7As shown, the collecting mechanism 7 also includes a heating collecting bin 75, which is arranged between the bottom shell 71 and the base 1. The heating collecting bin 75 receives the cleaned glue by the cleaning scraper 74. During use, the heating collecting bin 75 is installed, and the inclined plate on the side of the heating collecting bin 75 receives the glue cleaned by the cleaning scraper 74. The glue will flow into the heating collecting bin 75, and a heating component is installed in the heating collecting bin 75 to ensure the fluidity of the glue itself and prevent the glue from solidifying on the surface of the heating collecting bin 75 after cooling, thereby affecting the overall collection effect.
