Description

Technical Field

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

[0002] Cardboard, also known as board paper, is a thick paper sheet made by processing various pulp and interweaving fibers with each other. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard with a basis weight exceeding 250 g / m2 and a thickness greater than 0.5 mm is called cardboard. It is usually made from various plant fibers as raw materials, and non-plant fibers are also added. It is made by papermaking on a cardboard machine. Some special cardboard also contains animal fibers such as wool or mineral fibers such as asbestos.

[0003] During the production and processing of cardboard, glue is applied to the cardboard through a gluing device, and then the applied glue is brushed evenly through a roller, and then the cardboard is pasted and formed. The existing roller glue brushing device brushes the applied glue evenly through the roller. Although the amount of glue sprayed horizontally is the same, when the roller brushes the glue, the glue will move to both sides due to the extrusion of the roller, resulting in uneven thickness of the glue horizontally. Just brushing the glue with the roller will also cause uneven thickness of the glue horizontally. At the same time, when the roller brushes the glue, the glue will adhere to the roller, and a layer of glue on the roller will cause poor glue brushing effect on the subsequent 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 roller glue brushing device for cardboard production to solve the technical problems that the roller can only brush the glue longitudinally, the glue horizontally will be uneven in thickness, and at the same time, the roller brushing the glue will leave a layer of glue on the surface, which will affect the glue brushing effect of the subsequent cardboard.

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

[0006] A roller glue brushing device for cardboard production, including a support frame, a glue brushing roller and a brush for evenly applying glue on the cardboard are arranged above the support frame, a scraper for scraping the glue contaminated on the glue brushing roller is arranged above the support frame, a motor is fixedly installed above the support frame, and a transmission component is arranged between the motor and the glue brushing roller, the brush and the scraper.

[0007] Preferably, the transmission component includes a rotating shaft, the rotating shaft is rotatably connected above the support frame, the rotating shaft is fixedly installed at the output end of the motor, and the glue brushing roller is fixedly installed on the rotating shaft.

[0008] Preferably, a first rotating rod and a second rotating rod are rotatably connected to the support frame. A bevel gear set is arranged between the first rotating rod and the rotating shaft. A pulley set is sleeved between the first rotating rod and the second rotating rod.

[0009] Preferably, a limiting rod is slidably connected above the support frame. A spring is sleeved on the limiting rod. One end of the limiting rod is fixedly provided with a support block.

[0010] Preferably, a transmission block is fixedly installed above the second rotating rod. The transmission block is arranged in an elliptical shape, and the top of the transmission block abuts against one side of the support block.

[0011] Preferably, a brush is fixedly installed below the transmission block. A scraper is fixedly installed on one side of the transmission block. The scraper is in contact with one side of the glue-brushing roller.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The glue on the cardboard is longitudinally brushed by the rotating glue-brushing roller first. The cardboard passing through the glue-brushing roller will move to the lower part of the brush that reciprocates left and right, and the brush will horizontally brush the glue on the cardboard. In this way, the glue will be evenly brushed both horizontally and longitudinally. The roller is used to keep the maximum amount of glue on the cardboard passing through it, while the brush is used to evenly brush the horizontal amount of glue on the cardboard.

[0013] When the brush reciprocates left and right, the scraper will also reciprocate left and right along with the glue-brushing roller. The scraper will push the glue adhered to the glue-brushing roller to both sides, preventing a layer of glue from wrapping on the glue-brushing roller and affecting the subsequent brushing of glue on the cardboard.
