[0025] Example:

[0026] Reference Figures 1-5This utility model provides a cardboard box production gluing processing device, including a base frame 1 and a conveyor belt 5 for conveying cardboard mounted on the base frame 1. A fixed frame 6 is fixedly connected to the top of the base frame 1. The device also includes: a gluing roller 4, which is rotatably mounted on the fixed frame 6 via a spline shaft 201. The fixed frame 6 is provided with a drive unit for driving the gluing roller 4 to rotate; and sleeves 301 fixedly connected to both ends of the gluing roller 4. The sleeves 301 are laterally slidably mounted on the spline shaft 201. The fixed frame 6 is provided with a connecting part. When the drive unit drives the gluing roller 4 to rotate, the connecting part drives the gluing roller 4 to move laterally reciprocally.

[0027] During operation, cardboard is placed sequentially on conveyor belt 5. The glue-applying roller 4 is driven to rotate on the surface of the cardboard by the drive unit. With the cooperation of the connecting part, the glue-applying roller 4 is driven to move laterally back and forth on the surface of the cardboard, so that the glue application is more uniform and the glue application effect is improved.

[0028] The drive unit includes a motor 202 fixedly connected to the mounting bracket 6, and a splined shaft 201 fixedly connected to the output end of the motor 202. The connection unit includes a sliding seat 302 fixedly connected to the bottom of the mounting bracket 6. A bracket 303 is laterally slidably mounted on the sliding seat 302, and a ring 304 is fixedly connected to the bracket 303. The ring 304 is slidably mounted inside the sliding seat 302. A spring 305 is installed between the ring 304 and the inner wall of the sliding seat 302. A cam 307 is rotatably mounted on the mounting bracket 6 via a rotating shaft 306. The circumferential surface of the cam 307 contacts the bracket 303. The contact surface between the bracket 303 and the cam 307 is hemispherical. Sleeve 301 is rotatably connected to support 303. A limiting ring 311 is fixedly connected to sleeve 301. The limiting ring 311 is rotatably installed inside support 303. By setting the limiting ring 311, sleeve 301 can rotate on support 303, and support 303 can drive sleeve 301 to slide along spline shaft 201 through limiting ring 311. A drive shaft 308 is rotatably installed on fixed bracket 6. Drive shaft 308 and spline shaft 201 are connected by belt drive 309. Belt drive 309 is mainly composed of mating belts and pulleys. Bevel gears 310 are fixed on both drive shaft 308 and rotating shaft 306. The two bevel gears 310 are meshed and connected.

[0029] During operation, the motor 202 is started, and the output end of the motor 202 drives the spline shaft 201 to rotate. The spline shaft 201 drives the sleeve 301 to rotate, and the sleeve 301 drives the coating roller 4 to rotate on the surface of the cardboard. At the same time, the spline shaft 201 drives the transmission shaft 308 to rotate through the belt drive 309. The transmission shaft 308 drives the rotating shaft 306 to rotate through the bevel gear 310. The rotating shaft 306 drives the cam 307 to rotate. The cam 307 presses the bracket 303, causing the bracket 303 to slide on the sliding seat 302. The bracket 303 drives the ring 304 to slide in the sliding seat 302 and compress the spring 305. After that, the spring 305 returns to its original position, causing the bracket 303 to move laterally back and forth continuously. The bracket 303 drives the sleeve 301 to move laterally back and forth through the limit ring 311. The sleeve 301 drives the coating roller 4 to move laterally back and forth on the surface of the cardboard.

[0030] A horizontally arranged electric slide rail 7 is fixedly connected to the fixed frame 6. A slider 8 is slidably installed on the electric slide rail 7. A vertically arranged cylinder 9 is fixedly connected to the top of the slider 8. A fixed plate 10 is fixedly connected to the telescopic end of the cylinder 9. A suction cup 11 is fixedly connected to the top of the fixed plate 10. There are two suction cups 11, which are symmetrically arranged. In the initial state, the suction cups 11 are lower than the surface of the conveyor belt 5. There are two conveyor belts 5, which are symmetrically arranged front and back. The suction cups 11 are located between the two conveyor belts 5. A threaded rod 12 is threadedly connected to the base frame 1. A scraper 13 is rotatably installed on the threaded rod 12 through a bearing. The scraper 13 is in contact with the surface of the conveyor belt 5. The scraper 13 is used to scrape off the glue on the surface of the conveyor belt 5 in time to avoid affecting the subsequent glue application work. By rotating the threaded rod 12, the distance between the scraper 13 and the conveyor belt 5 can be adjusted to avoid excessive compression of the conveyor belt 5.

[0031] During operation, the cylinder 9 is activated, and its telescopic end drives the fixed plate 10 to rise. The fixed plate 10 drives the suction cup 11 to rise and contact the bottom of the cardboard to adsorb and fix it. Then, the cardboard is lifted from the surface of the conveyor belt 5 to contact the glue roller 4. The electric slide rail 7 is activated, so that the slider 8 slides laterally to transport the cardboard. After the glue is applied, the cardboard is placed on the conveyor belt 5.

[0032] In use, the cardboard is placed sequentially on the conveyor belt 5. When the cardboard moves above the suction cup 11, the conveyor belt 5 stops running, the cylinder 9 is activated, and its telescopic end drives the fixed plate 10 to rise. The fixed plate 10 drives the suction cup 11 to rise and contact the bottom of the cardboard, adsorbing and fixing it. Then, the cardboard is lifted from the surface of the conveyor belt 5 to contact the glue roller 4. The electric slide rail 7 is activated, so that the slider 8 slides laterally to transport the cardboard.

[0033] Next, the motor 202 is started. The output end of the motor 202 drives the spline shaft 201 to rotate. The spline shaft 201 drives the sleeve 301 to rotate. The sleeve 301 drives the glue coating roller 4 to rotate on the surface of the cardboard. At the same time, the spline shaft 201 drives the transmission shaft 308 to rotate through the belt drive 309. The transmission shaft 308 drives the rotating shaft 306 to rotate through the bevel gear 310. The rotating shaft 306 drives the cam 307 to rotate. The cam 307 presses the bracket 303, causing the bracket 303 to slide on the sliding seat 302. The bracket 303 drives the ring 304 to slide in the sliding seat 302 and compress the spring 305. Then the spring 305 returns to its original position, causing the bracket 303 to move laterally back and forth continuously. The bracket 303 drives the sleeve 301 to move laterally back and forth through the limiting ring 311. The sleeve 301 drives the glue coating roller 4 to move laterally back and forth on the surface of the cardboard, making the glue coating more uniform.
