Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to the following: Figures 1-6 This utility model provides a technical solution: a cardboard side coating device, including a coating table 100, two coating components, an electric slide rail 300, and an adjustment component 400. A top frame 200 is fixedly connected to the top outer surface of the coating table 100. The coating components are located between the coating table 100 and the top frame 200 and are used to coat the cardboard with glue. The electric slide rail 300 is installed on the top downward-facing outer surface of the top frame 200. The electric slide rail 300 is used to drive the coating components to move in the Y-axis direction. An inverted U-shaped frame 301 is installed at the output end of the electric slide rail 300, and a bottom of the inverted U-shaped frame 301 is installed with... The electric push rod 302 is used to drive the glue coating assembly to move in the Z-axis direction. The adjusting assembly 400 is located at the glue coating assembly and is used to adjust the distance between the two glue coating assemblies. Specifically, the cardboard is conveyed to the glue coating table 100. According to the size of the cardboard, the distance between the two glue coating assemblies is adjusted by the adjusting assembly 400 so that the two adjusting assemblies 400 are located on both sides of the cardboard. The electric push rod 302 works to make the glue coating assembly contact the cardboard, and the electric slide rail 300 works to make the glue coating assembly move on the cardboard to perform uniform glue coating on the side plate 405 of the cardboard.

[0019] Furthermore, the gluing assembly includes a gluing roller 406, the outer surface of which has a plurality of through grooves 407 arranged in a circumferential array. Specifically, glue is delivered into the interior of the gluing roller 406 and discharged through the through grooves 407 to perform gluing work on the surface of the cardboard.

[0020] Furthermore, the adjustment assembly 400 includes a gantry frame 401, which is mounted on the output end of the electric push rod 302. A positive and negative lead screw 402 is rotatably connected between the opposite outer surfaces of the left and right sides of the gantry frame 401. A motor 403 is mounted on the outer surface of the gantry frame 401, and the output end of the motor 403 is fixedly connected to the positive and negative lead screw 402. Two threaded blocks 404 are threadedly connected to the outer surface of the positive and negative lead screw 402. A side plate 405 is fixedly connected to the bottom outer surface of the threaded block 404. The outer surface of the device has a hollow tube that rotates through it, and the other end of the hollow tube is connected to the inside of the coating roller 406. Specifically, the distance between the two coating rollers 406 is adjusted according to the size of the cardboard. By turning on the motor 403, the motor 403 drives the positive and negative lead screws 402 to rotate. When the positive and negative lead screws 402 rotate, the threaded block 404 moves. When the threaded block 404 moves, it drives the coating rollers 406 to move, thereby adjusting the distance between the two coating rollers 406. This increases the applicability of the device and reduces glue waste.

[0021] Furthermore, an adhesive delivery assembly is provided above the top frame 200, which is used to deliver adhesive to the coating assembly.

[0022] Furthermore, the glue delivery assembly includes a glue storage cylinder 500 and a delivery pump 501 installed above the top frame 200. The input end of the delivery pump 501 is connected to the inside of the glue storage cylinder 500 through a suction pipe, and the output end of the delivery pump 501 is connected to a connecting pipe 502 through a discharge pipe. The outer surface of the connecting pipe 502 is connected to two telescopic pipes 503, and the other ends of the two telescopic pipes 503 extend to two hollow tubes respectively. Specifically, the delivery pump 501 extracts the glue from the glue storage cylinder 500 through the suction pipe and delivers the glue to the connecting pipe 502 through the discharge pipe. The glue enters the telescopic pipe 503 through the connecting pipe 502, enters the hollow tube through the telescopic pipe 503, and finally enters the glue coating roller 406.

[0023] Furthermore, one end of the hollow tube is connected to a rotary joint 408, and one end of the telescopic tube 503 is connected to the other end of the rotary joint 408. Specifically, under the action of the rotary joint 408, when the glue-coating roller 406 applies glue to the cardboard, the glue-coating roller 406 rotates, thereby causing relative rotation between the hollow tube and the telescopic tube 503. This allows the hollow tube to rotate without affecting the delivery of the glue.

[0024] Furthermore, mounting slots are provided on both the front and rear sides of the gluing table 100, and conveyor belts 600 are installed inside the mounting slots. Specifically, when the conveyor belt 600 is working, it transports the cardboard to the gluing table 100. When the conveyor belt 600 stops working, it stops transporting the cardboard. After the gluing work is completed, the conveyor belt 600 will transport the cardboard from the gluing table 100 to the outside.

[0025] Furthermore, a receiving groove is provided at the top center of the coating table 100, and a vacuum suction cup 700 is installed in the receiving groove. The top of the vacuum suction cup 700 is flush with the top of the coating table 100. One end of the vacuum suction cup 700 is connected to a vacuum tube 701, and the other end of the vacuum tube 701 is connected to an external vacuum generator. Specifically, the external vacuum generator generates suction through the vacuum tube 701, which is used to adsorb the cardboard through the vacuum suction cup 700, thereby increasing the stability of the cardboard during coating.

[0026] Furthermore, a groove 409 is provided on the top outer surface of the portal frame 401 facing downwards. A slider 410 is fixedly connected to the top outer surface of the threaded block 404. The slider 410 is slidably connected to the inside of the groove 409. Specifically, when the positive and negative screws 402 rotate, the threaded block 404 moves. The threaded block 404 drives the slider 410 to slide inside the groove 409. The groove 409 guides the movement of the slider 410, preventing the threaded block 404 from rotating with the rotation of the positive and negative screws 402.

[0027] Working Principle: In use, the cardboard to be coated is placed on the coating table 100. An external vacuum generator, through vacuum tube 701, generates suction that draws the cardboard into the vacuum suction cup 700. The distance between the two coating rollers 406 is adjusted according to the cardboard's size. The motor 403 is activated, driving the lead screw 402 to rotate. This rotation moves the threaded block 404, which in turn moves the coating rollers 406, thus adjusting the distance between them. An electric push rod 302 moves the coating rollers 406 downwards, positioning them at the desired positions. On both sides of the glued cardboard, the glue in the glue storage cylinder 500 is transported to the connecting pipe 502 by the operation of the conveying pump 501. The glue then enters the telescopic pipe 503 through the connecting pipe 502, and then enters the hollow pipe through the telescopic pipe 503, finally entering the glue coating roller 406. The glue is discharged through the through groove 407, and then the electric slide rail 300 operates to move the glue coating roller 406 on both sides of the cardboard, so that the glue coating roller 406 evenly coats both sides of the cardboard. This allows the position between the two glue coating rollers 406 to be adjusted according to the size of the cardboard, so that the glue coating rollers 406 are located on both sides of the cardboard to coat both sides of the cardboard, which increases the applicability of the device and reduces glue waste.
