[0002] Large packaging cartons are made of heavy corrugated cardboard. During carton production, whether the cartons are pre-formed or unformed for sale, glue needs to be pre-applied to the cardboard. Existing glue applicators mostly use fixed glue heads or single flow control, spraying only a corresponding amount of glue onto the cardboard surface after it passes through. However, the amount of glue at different locations on the glue strip cannot be controlled, often resulting in uneven glue application. This leads to quality problems and a high defect rate in the glued cartons. In view of this, the inventor has developed a new invention. Utility Model Content

[0021] The following is in conjunction with the appendix Figures 1 to 5 This utility model will be described in detail.

[0022] This utility model relates to an automatic gluing machine for composite paperboard production, comprising a base 1. A paperboard conveying mechanism 2, a material handling mechanism 3, and a gluing mechanism 4 are mounted on the upper surface of the base 1. The paperboard conveying mechanism 2 is used for feeding paperboard. The material handling mechanism 3 is used to receive paperboard and convey it to the gluing mechanism 4. The material handling mechanism 3 is a conveyor belt, a conventional component in this field, and its structure will not be described in detail here. The gluing mechanism 4 includes a glue storage tank 41 and an electric glue spraying assembly 42. The glue storage tank 41 is used to store glue and supply glue to the electric glue spraying assembly 42. The electric glue spraying assembly 42 includes at least a glue spraying head 43. The bottom end of the glue spraying head 43 is provided with a glue outlet 431, and a miniature glue coating roller 432 is installed at the rear end of the glue outlet 431.

[0023] This utility model improves the structure of the glue spray head 43 in existing glue spraying machines by adding a micro glue roller at the rear end of the spray nozzle. This allows the glue coater to simultaneously dispense glue and press the glue strip as the cardboard passes through it, thus better controlling the glue thickness at different positions on the glue strip. This achieves beneficial technical effects such as uniform glue application and improved finished product quality. The product of this technical solution is heavy corrugated cardboard. When placed on the conveyor belt, there is sufficient friction to prevent cardboard displacement. Therefore, the attached drawings do not illustrate this technical issue. If processing lighter cardboard, a cylinder-driven, liftable pressure roller can be installed below the glue coater. When the cardboard is conveyed to the correct position, the pressure roller presses down to effectively prevent cardboard displacement.

[0024] As one embodiment, the glue application mechanism 4 further includes a support frame 44, the glue storage tank 41 is disposed on the top surface of the support frame 44, and the electric glue spraying assembly 42 is disposed on the side wall of the support frame 44, such as... Figure 1 As shown, the support frame 44 serves as a support medium, assisting in fixing the two devices to the machine surface.

[0025] To further improve the technical solution, a liquid level sensor is installed on the inner wall of the glue storage tank 41, and the support frame 44 is also equipped with a glue replenishment tank 441 for replenishing glue to the storage tank 41. When the glue level in the storage tank 41 is lower than a threshold, the liquid level sensor sends a signal, and the glue in the replenishment tank 441 is pumped into the storage tank 41 to replenish the glue in a timely manner, preventing unexpected shutdowns. The equipment does not require constant personnel supervision, reducing labor costs.

[0026] As one embodiment, the electric glue spraying assembly 42 further includes a lateral drive module 45 and a longitudinal drive module 46. The lateral drive module 45 drives the longitudinal drive module 46 to move, and the longitudinal drive module 46 drives the glue spraying head 43 to move up and down. The lateral drive module 45 and the longitudinal drive module 46 improve the flexibility of the glue spraying head 43, allowing it to adapt to different glue spraying scenarios. The lateral drive module 45 and the longitudinal drive module 46 in this technical solution are existing linear components, and their structures are prior art; therefore, they will not be described in detail.

[0027] Preferably, the glue nozzle 43 is connected to the glue storage tank 41 via a glue tube, and a metering pump 47 is also provided between the glue tube and the glue storage tank 41. The metering pump 47 controls the amount of glue output per cycle to prevent glue waste.

[0028] In this technical solution, the cardboard conveying mechanism 2 includes a base 21, a placement rack 22 disposed on the base 21, and a drive assembly 23. The placement rack 22 is used to stack cardboard, and the drive assembly 23 is disposed at the bottom of the placement rack 22 and is used to convey the cardboard in the placement rack 22 one by one to the material conveying mechanism 3. The drive assembly 23 is a conveyor belt, and a gap is left between the drive assembly 23 and the placement rack 22 for the output of a single cardboard.

[0029] Preferably, the placement rack 22 is tilted toward the material conveying mechanism 3, so that the center of gravity of the cardboard is toward the material conveying mechanism 3, which helps the cardboard to be output from the placement rack 22 more easily.

[0030] Preferably, a traction mechanism 5 for assisting in the transport of cardboard is further provided between the drive assembly 23 and the conveying mechanism 3. The traction mechanism 5 includes at least a first traction assembly 51 and a second traction assembly 52 used in conjunction. The traction assembly is automatically powered to ensure that the cardboard has sufficient power to be conveyed, and also helps to speed up the transport of the cardboard.

[0031] In one embodiment, both the first traction assembly 51 and the second traction assembly 52 include an upper traction shaft 53, a lower traction shaft 54, and a drive motor 55 connected to the traction shafts via gear transmission. An upper conveyor wheel 531 is sleeved on the upper traction shaft 53, and a lower conveyor wheel 541 is sleeved on the lower traction shaft 54. A traction channel 56 is formed between the upper and lower conveyor wheels 531 and 541. When the drive motor 55 is activated, the upper and lower conveyor wheels 531 and 541 rotate, and the cardboard passes through the traction channel 56. The surfaces of the upper and lower conveyor wheels 531 and 541 are molded from a high-friction silicone material to better push the cardboard.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
