Description
Technical Field
[0001] The utility model relates to the technical field of corrugated paper production, in particular to a steam spraying device for producing corrugated paper. Background Art
[0002] Corrugated cardboard production involves corrugating rolls of base paper through processes such as corrugation, gluing, drying, cooling and shaping, slitting, creasing, and cross-cutting into standard cardboard sheets. Finally, qualified cardboard products are produced through conveying and stacking, achieving high-speed and efficient assembly line operations. During corrugation, the core paper 6 must be humidified before being pressed into flutes to increase its flexibility and prevent breakage during pressing. Currently, humidification of the core paper 6 is uneven, with some areas being over-humidified or under-humidified, making the core paper 6 too soft or brittle, which can easily break during pressing.

[0013] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.
[0014] like Figure 1-3 As shown, the utility model provides a steam spraying device for producing corrugated paper, comprising a frame 1, a transmission roller 2, a steam generator 3, a steam spraying pipe 4, and an air pump 5; the transmission roller 2 is installed on the inner wall of the frame 1, and the core paper 6 contacts the transmission roller 2 and moves forward under the transmission of the transmission roller 2, and the front end of the core paper 6 is connected to the corrugated roller and pressed into a wave shape; the steam generator 3 is installed at the bottom of the frame 1, below the core paper 6; a conical steam collector 7 is installed on the top of the steam generator 3, and the top of the steam collector 7 is connected to two air pumps 5 arranged on both sides of the steam generator 3 through two connecting pipes 8; the two air pumps 5 are respectively connected to the steam spraying pipe 4; the front ends of the two steam spraying pipes 4 are provided with horizontal sections, which are respectively located above and below the core paper 6, and the side walls of the horizontal sections of the two steam spraying pipes 4 are evenly provided with spray ports 9 facing the core paper 6. When the present invention is in use, the roll core paper 6 is installed on the transmission roller 2, and the front end is connected to the corrugated roller. Under the drive of the corrugated roller and the transmission roller 2, the core paper 6 moves forward, and the steam generator 3 generates steam. Under the negative pressure of the air pump 5, the steam is absorbed and passes through the steam collector 7, the connecting pipe 8, and the steam spray pipe 4, so that the spray port 9 on the spray pipe sprays out to act on the core paper 6 to humidify the core paper 6. Steam spray pipes 4 are provided on the upper and lower sides of the core paper 6, which can spray both sides of the core paper 6 at the same time, so that the steam sprays the core paper 6 evenly, which is beneficial to pressing the core paper 6 into fluting and avoiding damage to the core paper 6 during pressing.

The motor 10 drives the transmission roller 2 to rotate. Under the drive of the corrugated roller and the transmission roller 2, the core paper 6 moves forward, and the steam generator 3 generates steam. Under the negative pressure of the air pump 5, the steam is absorbed and passes through the steam collector 7, the connecting pipe 8, and the steam spray pipe 4, so that the spray port 9 on the spray pipe sprays out to act on the core paper 6 to humidify the core paper 6. Steam spray pipes 4 are provided on the upper and lower sides of the core paper 6, which can spray both sides of the core paper 6 at the same time, so that the steam sprays the core paper 6 evenly, which is conducive to pressing the core paper 6 into fluting and avoiding damage to the core paper 6 during pressing.
