Description

Technical Field

[0001] The utility model relates to the technical field of production of impregnated paper, in particular to a drying device for production of impregnated paper. Background Art

[0002] Melamine impregnated paper, also known as melamine impregnated paper, or melamine paper for short, refers to the offset paper that is impregnated with amino resin on solid color base paper or printed decorative paper. After drying to a certain extent, it can be hot-pressed and bonded together or bonded to the substrate of artificial board. It is mainly produced through horizontal impregnation and drying production lines.

[0003] During the production of impregnated paper, it needs to be impregnated in amino resin and then dried by hot drying equipment. After rapid drying by the drying equipment, some water vapor on its surface cannot be quickly extracted, resulting in high surface humidity. It needs to be completely cooled before the humidity can be reduced. Therefore, a wind drying device is needed to further cool and dry the dried impregnated paper. The existing wind drying device has a constant contact area between the airflow and the surface of the impregnated paper, which results in the inability to improve the drying effect when the humidity is high, and is not suitable for the automatic adjustment needs of automated production.

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0025] like Figure 1-5 A drying device for producing impregnated paper is shown, comprising a material guiding mechanism 1 and an air-drying device 2. The material guiding mechanism 1 is arranged on the outside of both sides of the air-drying device 2. The material guiding mechanism 1 comprises a first gantry 11, a material guiding roller 12, a mounting seat 13, a sleeve 14, a folding plate 15, a connecting shaft 16, a pressure roller 17 and a first oil cylinder 18. The material guiding roller 12 is movably connected to the top of the inner side of the first gantry 11, the mounting seat 13 is fixedly arranged on the outer side of the first gantry 11, the sleeve 14 is movably connected to the mounting seat 13, the folding plate 15 is fixedly arranged on the outer surface of the sleeve 14, the connecting shaft 16 is fixedly arranged at the bottom end of the folding plate 15, the pressure roller 17 is movably connected to the connecting shaft 16, and the first oil cylinder 18 is installed on the back of the first gantry 11.

[0026] Specifically, the air drying device 2 includes a second gantry 21, a shielding cover 22, an air inlet pipe 23, a second oil cylinder 24, a lifting air outlet cover 25, a connecting plate 26 and a contact roller 27. The shielding cover 22 is fixedly arranged on the inner side of the top of the second gantry 21, the air inlet pipe 23 is fixedly arranged on the top of the second gantry 21, the second oil cylinder 24 is installed on the top of the second gantry 21, the lifting air outlet cover 25 is clamped on the inner side of the bottom of the shielding cover 22, the connecting plates 26 are fixedly arranged at both ends of the bottom of the lifting air outlet cover 25, and the contact roller 27 is movably connected with the connecting plate 26. Then, the bottom end of the air inlet pipe 23 passes through the top of the second gantry 21 and extends to the inner side of the top of the shielding cover 22. An air outlet hole is vertically opened on the outside of the lifting air outlet cover 25. A sealing gasket is sleeved on the outside of the top of the air outlet cover 25. The outer wall of the sealing gasket on the outside of the air outlet cover 25 fits with the inner wall of the shielding cover 22. The telescopic end of the first oil cylinder 18 contacts the back of the folding plate 15. The telescopic end of the first oil cylinder 18 drives the folding plate 15 to rotate around the sleeve 14. The telescopic end of the second oil cylinder 24 is connected to the top of the lifting air outlet cover 25, and an air inlet hole is opened on the top of the lifting air outlet cover 25.

[0027] In this embodiment, the impregnated paper passes through the top of the guide roller 12 at the top of the inner side of the first gantry 11 on one side, and passes through the bottom of the contact roller 27 and then passes through the top of the guide roller 12 on the inner side of the first gantry 11 on the other side, so that the impregnated paper is arranged in a V shape, and the bottom end of the impregnated paper contacts the bottom of the contact roller 27, thereby ensuring that the bottom air outlet and the impregnated paper maintain a constant height. After the air pump enters through the air inlet pipe 23 at the top of the second gantry 21, it flows out from the bottom of the lifting air outlet hood 25 through the shielding cover 22, acts on the surface of the impregnated paper, thereby blowing away the residual water vapor after heat drying and cooling the impregnated paper, thereby ensuring that the impregnated paper is dry.

[0028] Furthermore, when the sensor detects that the humidity on the surface of the dried impregnated paper is still too high, the control device controls the second oil cylinder 24 to extend and push the lifting air outlet hood 25 downward, so that the contact roller 27 presses down on the impregnated paper. As the lifting air outlet hood 25 descends, the air outlet holes arranged vertically on the side are exposed, so that the airflow rushes out from the air outlet holes on the side of the lifting air outlet hood 25, acts on the surface of the impregnated paper, increases the contact area between the airflow and the impregnated paper, and increases the contact time, so as to better achieve the drying effect. In this process, the first oil cylinder 18 extends, and its telescopic end acts on the back of the folding plate 15 to lift the folding plate 15, so that the sleeve 14 rotates around the clamping shaft inside the mounting seat 13, so that the pressure roller 17 rises, and pressure is applied to the back side of the impregnated paper, so that the distance between the impregnated paper and the air outlet holes on the side of the lifting air outlet hood 25 is closer, thereby further improving the drying effect.

[0029] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
