Spraying device for applying glue to corrugated paper boards

Abstract

The invention discloses a spraying device for applying glue to corrugated paper boards. The spraying device comprises a workbench. A glue tank is arranged in the center of the upper surface of the workbench. A second fixing bracket is arranged at the position, close to the glue tank, of the upper surface of the workbench. A glue application roll is connected to the position, close to the bottom end, of the side face of the second fixing bracket in a rotary manner. An electric extending-and-contracting rod is arranged at the position, close to the glue application roll, of the side face of theglue tank. A scraping plate is arranged at the end of the electric extending-and-contracting rod. A glue uniformizing roll is connected to the middle of the side face of the second fixing bracket in arotary manner. The spraying device for applying the glue to the corrugated paper boards is provided with a first fixing bracket, rotating shafts, a conveying belt and a second servo motor, and the corrugated paper boards can be delivered to the position of the glue uniformizing roll for glue application operation; simpleness, rapidness and convenience are achieved; by means of a tray and fixing pillars, the corrugated paper boards can be taken to the next procedure for operation conveniently, and the problem that the glue adheres to other places to affect product quality can be prevented; bymeans of the electric extending-and-contracting rod, the distance between the scraping plate and the glue application roll can be controlled conveniently; and the spraying device is convenient and fast to use.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production, in particular to a corrugated cardboard glue spraying device. Background technique [0002] At present, corrugated cardboard includes face paper, corrugated core paper and bottom paper. In the production process, the face paper and corrugated core paper are first bonded, and then the bottom paper is bonded. Glue on the corrugated medium paper will squeeze and stretch the cardboard when the glue is applied by the glue roller. If the cardboard is too dry, it will cause uneven glue coating and cardboard cracking, which will affect the quality of cardboard bonding. [0003] For example, the patent application publication number CN207273989U discloses a glue spraying device on corrugated cardboard, which includes a frame, a glue box, a top roller, a glue roller, a paper pressing roller, a paper humidifier and a corrugated paper humidifier. The humidifier and the corrugated pap...

Problems solved by technology

[0002] At present, corrugated cardboard includes face paper, corrugated core paper and bottom paper. In the production process, the face paper and corrugated core paper are first bonded, and then the bottom paper is bonded. Glue on the corrugated medium paper, when the glue is applied by the glue roller, the cardboard will be squeezed and stretched to a certain extent. If the cardboard is too dry, it will cause uneven glue coating and cardboard cracking, which will affect the quality of cardboard bonding.

[0003] For example, the patent application publication number CN207273989U discloses a glue spraying device on corrugated cardboard, which includes a frame, a glue box, a top roller, a glue roller, a paper pressing roller, a paper humidifier and a corrugated paper humidifier. The humidifier and the corrugated paper humidifier are respectively composed of a cover body and a spray nozzle installed in the cover body. The bottom end of the cover body of the facial tissue humidifier is equipped with a guide roller, and the other end is provided with a sponge roller. There are a pair of rollers, but the corrugated cardboard glue spray device is inconvenient to send the corrugated cardboard to the vicinity of the glue roller, which affects the work efficiency, and it is inconvenient to transport the corrugated cardboard to the next process, and it is inconvenient to adjust the distance between the scraper and the top roller , more inconvenient to use
