[0001] The utility model relates to the technical field of grey board production, in particular to a gluing device for making composite grey boards. Background Art

[0002] Composite grey board is a kind of board material synthesized by multiple layers of cardboard through processes such as gluing, pressing, and drying in a certain proportion. It combines the advantages of multiple layers of cardboard and has characteristics such as a strong structure, strong impact resistance, good moisture resistance, and good shock resistance. Therefore, it is widely used in many fields such as electronic product packaging, gift packaging, furniture back panels, stationery supplies, and advertising boards. During the production process of grey board, a gluing device is required to operate the gluing process on it.

[0003] However, the following problems exist in the existing equipment: after the equipment performs gluing operations for a long time, some glue is likely to adhere to its workbench. After the glue solidifies, it is easy to make the workbench uneven, resulting in uneven placement of the subsequent grey board, thereby affecting the gluing quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that after the existing equipment performs gluing operations for a long time, some glue is likely to adhere to its workbench. After the glue solidifies, it is easy to make the workbench uneven, resulting in uneven placement of the subsequent grey board, thereby affecting the gluing quality, and to propose a gluing device for making composite grey boards.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The output shaft of the first motor is rotatably connected to the workbench and the rear plate. A rectangular groove is formed in the front side of the rear plate. Two ends of the first lead screw are respectively rotatably connected to the top inner wall and the bottom inner wall of the same rectangular groove. The first connecting plate is threadedly sleeved on the first lead screw and is slidably connected to the rectangular groove. The top and bottom of the two positioning rods are respectively fixedly connected to the bottom of the top plate and the top of the workbench. The two second connecting plates are respectively slidably sleeved on the two positioning rods and are slidably connected to the rear plate. One side of the first connecting plate and the two second connecting plates are fixedly connected to the same lifting frame. A glue spray head for applying glue to the grey cardboard is arranged below the lifting frame.

[0011] In a possible design, the moving mechanism includes a second motor, a second lead screw, a first moving block, a bottom block and a coating roller. The lifting frame is U-shaped. One side of the second motor is fixedly connected to one side of the lifting frame by bolts. The output end of the second motor penetrates through one side of the lifting frame and is fixedly connected to one end of the second lead screw. The output shaft of the second motor is rotatably connected to the lifting frame. Two ends of the second lead screw are respectively rotatably connected to the inner walls of the two sides of the same lifting frame. The first moving block is threadedly sleeved on the second lead screw and is slidably connected to the lifting frame. The bottom of the first moving block is fixedly connected to the top of the bottom block. One front side and one rear side of the bottom block are both fixedly connected with a first plate by bolts. One end of two bent columns is respectively rotatably connected to two ends of the same coating roller. The two glue spray heads are both arranged on one side of the same bottom block. A pump body for facilitating glue application is fixedly arranged on the front side of the bottom block. The liquid outlet end of the pump body is connected to the glue spray head through a first pipe. The liquid inlet end of the pump body is fixedly connected with a second pipe, and the second pipe is connected to an external glue storage tank.

[0012] In a possible design, the cleaning mechanism includes a third motor, a third lead screw, a front box, a second moving block, an L-shaped plate, a cleaning block, and a triangular plate. The rear side of the front box is fixedly connected to the front side of the workbench. One side of the third motor is fixedly connected to one side of the front box through bolts. The output shaft of the third motor penetrates through one side of the front box and is fixedly connected to one end of the third lead screw. The output shaft of the third motor is rotatably connected to the front box. The two ends of the third lead screw are respectively rotatably connected to the inner walls of both sides of the same front box. The second moving block is threadedly sleeved on the third lead screw. The outer side of the second moving block is slidably connected to the inner wall of the front box. The bottom of the L-shaped plate is fixedly connected to the top of the second moving block. The rear side of the L-shaped plate is fixedly connected to the front side of the cleaning block. The bottom of the cleaning block is in contact with the top of the workbench. One side of the cleaning block is fixedly connected to one side of the triangular plate.

[0013] In a possible design, a first baffle for facilitating the orderly arrangement of grey cardboard is fixedly connected to the top of the workbench. A second baffle for preventing impurities from falling into the front box is fixedly connected to one side of the top of the front box. The front side and the rear side of the cleaning block are respectively slidably connected to the closer sides of the first baffle and the second baffle. The second baffle is located below the L-shaped plate.

[0014] In a possible design, a collection box for facilitating the collection of impurities cleaned out from the workbench is fixedly connected to one side of the workbench.

[0015] In this application, when in use, place the grey cardboard to be coated with glue on the workbench and arrange it orderly through the baffle. When it is necessary to adjust the height of the glue nozzle to adapt to grey cardboard of different thicknesses, the controller sends a signal to the first motor, and the first motor starts and drives the first lead screw to rotate. Since the first connecting plate is threadedly connected to the first lead screw and is restricted to slide within the rectangular groove, the rotation of the first lead screw will drive the first connecting plate to move up and down. At the same time, the two second connecting plates also move together under the guidance of the positioning rods, thereby driving the entire lifting frame and the glue nozzle below it to lift and lower, realizing the glue coating operation on grey cardboard of different thicknesses. After the lifting frame reaches the predetermined height, the controller starts the second motor, and the second motor drives the second lead screw to rotate. The first moving block is threadedly connected to the second lead screw, so the rotation of the second lead screw will cause the first moving block to move left and right within the lifting frame. The movement of the first moving block drives the bottom block and the coating roller and the glue nozzle on it to move synchronously, and sprays glue on the grey cardboard, and then coats it through the coating roller, realizing the uniform coating of the surface of the grey cardboard. The moving mechanism adopts screw drive to ensure that the coating roller and the glue nozzle can move smoothly and accurately on the surface of the grey cardboard, realizing uniform glue coating, avoiding the problem of uneven thickness that may occur in traditional manual glue coating. After the glue coating operation is completed, after the glue coating is completed, take the grey cardboard after glue coating, and then start the third motor through the controller. The third motor drives the third lead screw to rotate, making the second moving block move left and right within the front box. The movement of the second moving block drives the cleaning block to slide on the surface of the workbench through the L-shaped plate. The combined design of the cleaning block and the triangular plate enhances the cleaning effect, effectively removing the glue residue and impurities on the workbench. When the impurities are pushed by the cleaning block, they are collected through the collection box on one side of the workbench.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, through the lifting mechanism, the moving mechanism and the cleaning mechanism, it is possible to automatically adjust the height of the glue nozzle according to grey cardboard of different thicknesses, realize precise glue coating, improve production efficiency and glue coating quality, make the cleaning of the workbench surface simple and fast, reduce the shutdown maintenance time, improve the overall operation efficiency of the equipment, and at the same time prevent the grey cardboard from being uneven when placed, ensuring the glue coating quality.
