Description

Technical Field

[0001] The utility model mainly relates to the technical field of cardboard production and processing, and specifically relates to a glue discharging device for cardboard production. Background Technique

[0002] In the manufacturing process of cardboard, it is necessary to first make the pulp into cardboard, then apply various coating layers on the cardboard, and finally cover a 0.1-mm-thick flexible reinforcement layer that is light-transmitting on the cardboard to obtain a complete special cardboard. The latest method currently is to adopt a roll coating process, directly using the roll coating method to make a 0.1-mm-thick flexible reinforcement layer on a 1.1-mm-thick cardboard, that is, roll coating a layer of tough glue on the cardboard to form the flexible reinforcement layer.

[0003] For the existing glue discharging device, the glue is usually sprayed on the coating roller through a nozzle, and then the coating roller rotates to continuously apply glue to the cardboard. However, spraying the glue on the coating roller through the nozzle will result in too much glue, and when the coating roller applies the glue on the cardboard, there will be too much glue on the cardboard, causing it to continuously slide downwards, resulting in waste of glue droplets and pollution, and at the same time, too much glue on the cardboard will also cause the cardboard to be soaked by the glue, easily causing damage to the cardboard. Content of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution significantly different from the existing technology. It mainly provides a glue discharging device for cardboard production to solve the technical problem proposed in the above background technique that spraying the glue on the coating roller through a nozzle and then applying the glue to the cardboard by the coating roller will result in too much glue on the cardboard, the glue will slide down and drip, causing waste of glue and pollution of the device by the glue, and at the same time, too much glue is likely to soak the cardboard, causing damage to the cardboard.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A glue discharging device for cardboard production, comprising a support frame, on which a conveying assembly for driving the cardboard to move continuously is arranged, above the support frame, a glue coating roller for continuously coating glue on the cardboard is arranged, above the support frame, a glue storage assembly for storing glue is arranged, and above the glue storage assembly, a scraping brush for scraping off excessive glue on the glue coating roller is arranged. The conveying assembly includes a paper unwinding roller and a paper rewinding roller, the paper unwinding roller and the paper rewinding roller are respectively rotatably connected to the support frame, the paper unwinding roller releases the cardboard and winds it around the paper rewinding roller, a motor is fixedly installed on the support frame, the output end of the motor is fixedly connected to the paper rewinding roller, the motor drives the paper rewinding roller to rotate to wind the cardboard, and at the same time, the cardboard pulls the paper unwinding roller to rotate. A limiting roller is rotatably connected to the support frame, and the limiting roller is used to push the cardboard to fit against one side of the glue coating roller. A pulley group is sleeved between the glue coating roller and the limiting roller, and spaced grooves are formed on the glue coating roller.

[0007] Preferably, the glue storage assembly includes a glue storage tank, the glue storage tank is fixedly installed above the support frame, and a scraping brush is fixedly installed on one side above the glue storage tank.

[0008] Preferably, the glue storage assembly further includes a glue storage box, the glue storage box is fixedly installed on the support frame, and the glue storage box is communicated with the glue storage tank through a conveying pipeline.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The lower side of the glue coating roller is immersed in the glue in the glue storage tank, and the glue coating roller continuously rotates to carry the glue and rotate. And the glue coating roller that rotates out of the glue storage tank will first scrape off a part of the glue through the scraping brush, so that there is not so much glue carried on the glue coating roller, so that the glue applied to the cardboard will not be excessive. At the same time, the glue scraped off by the scraping brush will drip into the glue storage tank, so that no pollution will be caused.

[0010] Spaced grooves are formed on the glue coating roller at intervals, so that the glue coating roller in contact with the cardboard contacts in sections. In this way, when the glue coating roller applies glue, the glue applied to the cardboard is also in sections. Then, through subsequent processes, these glues are evenly applied, so that the glue on the cardboard will not be excessive. If such spaced grooves are not formed, the entire surface of the glue coating roller contacts the cardboard, which will cause excessive glue applied to the cardboard and it cannot be spread evenly in the subsequent processes.

A material storage assembly for storing glue is arranged above the support frame 1, and a scraping brush 11 for scraping off excessive glue on the glue coating roller 6 is arranged above the material storage assembly.

[0022] The specific operation process of this utility model is as follows: Start the motor 5, and the motor 5 drives the recovery roller 2 to rotate. The recovery roller 2 continuously pulls the cardboard to move through rotation. The cardboard drives the unwinding roller 3 and the limiting roller 4 to rotate. The cardboard starts from the unwinding roller 3, passes through the limiting roller 4, and the limiting roller 4 fits one side of the cardboard against the glue applicator roller 6. At the same time, the limiting roller 4 drives the glue applicator roller 6 to rotate through the pulley group 7. The glue applicator roller 6 continuously rotates to apply the glue inside the lower glue storage tank 8 onto the upper part of the glue applicator roller 6. Then, the glue applicator roller 6 rotates to carry the glue and move. After the glue applicator roller 6 rotates out of the glue storage tank 8, it will pass through the scraping brush 11, and the scraping brush 11 will scrape off a part of the glue on the glue applicator roller 6 and drip it back into the glue storage tank 8. After being scraped by the scraping brush 11, the glue applicator roller 6 rotates and contacts the cardboard, and the glue applicator roller 6 applies the glue onto the cardboard. The cardboard continues to move through the pulling of the recovery roller 2 and enters the next process.

[0023] Please refer to Figures 1 - 4 , the conveying component includes an unwinding roller 3 and a recovery roller 2. The unwinding roller 3 and the recovery roller 2 are respectively rotatably connected to the support frame 1. The unwinding roller 3 releases the cardboard and winds it around the recovery roller 2. A motor 5 is fixedly installed on the support frame 1, and the output end of the motor 5 is fixedly connected to the recovery roller 2. The motor 5 drives the recovery roller 2 to rotate to wind up the cardboard, and at the same time, the cardboard pulls the unwinding roller 3 to rotate. A limiting roller 4 is rotatably connected to the support frame 1, and the limiting roller 4 is used to push one side of the cardboard against the glue applicator roller 6. A pulley group 7 is sleeved between the glue applicator roller 6 and the limiting roller 4, and an interval groove 12 is provided on the glue applicator roller 6.

[0024] The cardboard starts from the unwinding roller 3, passes through the limiting roller 4, and the limiting roller 4 presses one side of the cardboard against the glue applicator roller 6. One end of the cardboard is wound around the recovery roller 2. Start the motor 5, and the motor 5 drives the recovery roller 2 to rotate. The recovery roller 2 drives the cardboard to wind around the recovery roller 2 one by one through rotation. The cardboard is pulled by the recovery roller 2 to move. The cardboard will pull the unwinding roller 3 and the limiting roller 4 to rotate. The limiting roller 4 drives the glue applicator roller 6 to rotate through the pulley group 7. The glue applicator roller 6 continuously rotates to apply the glue onto the cardboard through rotation. And an interval groove 12 is provided on the glue applicator roller 6, so that the glue applied onto the cardboard will have intervals. Because usually, more glue is applied onto the cardboard through the roller, and then the glue is scraped evenly by subsequent scraping equipment in such intervals, the glue on the cardboard will be just right. If such an interval groove 12 is not provided, after the glue is scraped evenly by the subsequent scraping equipment, the glue will still be too thick.

[0025] Please refer to Figures 1 - 4 , the storage component includes a glue storage tank 8. The glue storage tank 8 is fixedly installed above the support frame 1. A scraping brush 11 is fixedly installed on one side above the glue storage tank 8. The storage component further includes a glue storage box 9. The glue storage box 9 is fixedly installed on the support frame 1, and the glue storage box 9 is communicated with the glue storage tank 8 through a conveying pipeline 10.

[0026] The glue storage box 9 stores glue inside. The glue inside the glue storage box 9 is transported into the glue storage tank 8 through the transport pipeline 10, and there are multiple transport pipelines 10, so as to ensure uniform transportation of the glue inside the glue storage tank 8. An opening is provided above the glue storage tank 8. The lower side of the glue applicator roller 6 is immersed in the glue inside the glue storage tank 8 through the opening. The rotation of the glue applicator roller 6 continuously drives the glue out of the glue storage tank 8, and the rotating glue applicator roller 6 will pass by the scraping brush 11. The scraping brush 11 will scrape off the glue on the glue applicator roller 6, so that there is not so much glue on the glue applicator roller 6. In this way, the glue applied by the glue applicator roller 6 on the cardboard will not be excessive. The glue scraped off by the scraping brush 11 will drip back into the glue storage tank 8, preventing the glue from dripping onto the equipment and causing waste and pollution.
