Embodiment 1
[0051] see figure 1 , the present invention provides a technical solution: a high flame-retardant corrugated paper production process, comprising the following steps:
[0052] Step 1: Material preparation: core paper and surface paper of corrugated paper, flame retardant liquid, coating machine, gluing machine and glue;
[0053] Step 2: Pretreatment: place the corrugated cardboard in a constant temperature box with a humidity of 8-12RH for 15-18h;
[0054] Step 3: Flame retardant liquid coating: Coat the corrugated paper prepared in step 2 with a wetting layer on both sides of the coating machine, and after drying, apply a flame retardant liquid on both sides of the corrugated paper; first coat the wetting layer on the surface of the corrugated paper, After drying the surface, further coat the flame retardant liquid to prevent the flame retardant liquid from soaking into the corrugated paper after coating, so as to ensure that the flame retardant liquid forms a protective lay...
Embodiment 2
[0058] see Figure 2-4 , the invention provides a kind of technical scheme: gluing machine comprises:
[0059] Chassis 1, the chassis 1 has a square box, and a drive motor 2 installed on the front of the square box, and a glue injection pump 3 installed on the back of the square box, and a compound mechanism 4 arranged in the inner cavity of the square box, and the installation In the recovery box 5 on the right side of the bottom of the square box cavity, the composite mechanism 4 includes:
[0060] Electromagnetic mechanism 41, this electromagnetic mechanism 41 has bottom electromagnetic block and top electromagnetic block with identical structure, and the suspension magnetic bar 42 that is arranged between bottom electromagnetic block and top electromagnetic block, and is arranged on suspension magnetic bar 42 and described bottom electromagnetic block and the guide mechanism 43 between the top electromagnetic block; the electromagnetic force is generated through the trans...
Embodiment 3
[0065] see Figure 2-5 On the basis of the second implementation, the present invention provides a technical solution: the electromagnetic mechanism 41 includes a protection box 411, a U-shaped core rod 412 arranged at the bottom of the inner cavity of the protection box 411, and a U-shaped core rod 412 sleeved outside the U-shaped core rod 412. The current coil 413 on the surface, the air-permeable partition 414 installed in the middle of the inner wall of the protection box 411 , and the arc guide plate 415 installed on the top of the inner cavity of the protection box 411 . Through the design of the U-shaped core rod 412, the magnetic fields are superimposed on each other to ensure the stability of the magnetic support. At the same time, the heat generated by itself initially heats up the corrugated paper, which is convenient for increasing the speed of the solidification of the glue. The curved guide plate 415 is used to Directional transmission of heat airflow promotes th...
