Description

Technical Field

[0001] This utility model relates to the field of door product manufacturing technology, and in particular to a drying device for honeycomb paper production. Background Technology

[0002] Honeycomb paperboard is made based on the principle of honeycomb structure in nature. It is a new type of environmentally friendly and energy-saving sandwich structure material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component - honeycomb paper core, and then bonding face paper to both sides of it.

[0003] In the production process of honeycomb paperboard, the honeycomb paper core needs to be stretched and shaped first. The honeycomb paper core needs to go through stretching, drying and other processes during the shaping process.

[0004] Existing baking devices (such as the patent with publication number CN210940701U) are directly connected to the drying chamber via a hot air chamber through an air pipe. An electric heating device is installed in the hot air chamber. With such a structure, the air supply point is fixed, and the temperature around the connection between the air pipe and the drying chamber is much higher than other parts, which will lead to uneven temperature in the drying chamber. Secondly, electric heating has low heating efficiency and high electricity cost. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drying device for honeycomb paper production.

[0006] The objective of this utility model is achieved through the following technical solution: A drying device for honeycomb paper production includes a drying box, wherein a hot air pipe is provided at the bottom of the drying box and the hot air pipe is arranged along the length of the drying box. The hot air duct is connected to multiple air distribution ducts distributed along the width of the drying box, and multiple air outlets are evenly distributed on the air distribution ducts. The drying chamber is equipped with a burner on the outside, and the hot air outlet of the burner is connected to the hot air pipe.

[0007] Furthermore, the air outlet is inclined towards the bottom of the drying chamber.

[0008] Furthermore, multiple air outlets are arranged alternately along the axial direction of the air distribution duct, with their air outlet directions respectively facing the first and last ends of the drying box.

[0009] Furthermore, the drying chamber is equipped with multiple fans.

[0010] Furthermore, the axis of the air distribution duct is perpendicular to the axis of the hot air duct.

[0011] Furthermore, the diameter of the hot air duct is larger than the diameter of the air distribution duct.

[0012] Furthermore, the multiple air distribution ducts are symmetrically arranged with the axis of the hot air duct as the axis of symmetry.

[0013] Furthermore, the bottom of the drying oven is provided with a right-angle plate, the horizontal section of which is detachably connected to the bottom of the drying oven, and the vertical section of which is provided with an arc-shaped support groove adapted to the outer diameter of the air distribution pipe, and the air distribution pipe is disposed in the arc-shaped support groove.

[0014] Furthermore, the horizontal section of the right-angle plate is connected to the bottom of the drying oven by bolts.

[0015] The beneficial effects of this utility model are: This invention uses a distribution pipe connected to the hot air pipe to ensure that the hot air is evenly distributed in the drying chamber. The downward-sloping air outlets prevent the hot air from directly spraying onto the honeycomb paper, thus avoiding the heat from concentrating at a single point on the honeycomb paper.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1-3 This utility model provides a technical solution: Example: like Figures 1-3 As shown, a drying device for honeycomb paper production includes a drying box 1, and a hot air pipe 2 is provided at the bottom of the drying box 1. The hot air pipe 2 is arranged along the length of the drying box 1. The hot air duct 2 is connected to a plurality of branch air ducts 3 distributed along the width of the drying chamber 1. The plurality of branch air ducts 3 are symmetrically arranged about the axis of the hot air duct 2. In this embodiment, the axis of the branch air duct is perpendicular to the axis of the hot air duct 2, and the diameter of the hot air duct 2 is larger than the diameter of the branch air duct. The branch air duct 3 is evenly distributed with a plurality of air outlet holes 4. The drying chamber 1 is equipped with a burner 5 on the outside, and the hot air outlet of the burner 5 is connected to the hot air pipe 2.

[0019] like Figure 3 As shown, the air outlet 4 is inclined toward the bottom of the drying box 1 (the inclination angle is 0-90 degrees, and 45 degrees in this embodiment. The inclination angle refers to the angle between the axis of the air outlet 4 and the axis perpendicular to the horizontal plane).

[0020] Multiple air outlets 4 are arranged alternately along the axial direction of the air distribution pipe 3, with their air outlet directions facing the first and last ends of the drying box 1 respectively (alternate arrangement here means that the air outlets 4 with the air outlet direction facing the first end of the drying box 1 and the air outlets 4 with the air outlet direction facing the last end of the drying box 1 are arranged alternately).

[0021] The drying chamber 1 is equipped with multiple fans 6. The fans 6 are used to pick up the hot air sprayed from the air distribution pipe 3 toward the bottom of the drying chamber 1, so that the hot air rises and heats the honeycomb paper.

[0022] The bottom of the drying oven 1 is provided with a right-angle plate 7. The horizontal section of the right-angle plate 7 is detachably connected to the bottom of the drying oven 1 by bolts. The vertical section of the right-angle plate 7 is provided with an arc-shaped support groove that matches the outer diameter of the air distribution pipe. The air distribution pipe 3 is set in the arc-shaped support groove.

[0023] Working principle: Hot air is continuously supplied to the drying chamber 1 by the burner 5. The hot air enters the distribution pipe 3 through the hot air pipe 2 and is then sprayed towards the bottom of the drying chamber 1 through the air outlet 4, rebounding towards the honeycomb paper. At the same time, the fan 6 picks up the hot air sprayed from the air outlet 4, causing the hot air to rise and heat the stretched honeycomb paper, thus shaping it. The downward tilt of the air outlet 4 avoids the hot air directly spraying onto the honeycomb paper, which would cause the heat to concentrate at one point on the honeycomb paper (heat concentration would damage the honeycomb paper).

[0024] Meanwhile, the air outlets 4, which are alternately positioned so that the air outlets at the beginning and end of the drying chamber 1, can further ensure that the hot air is evenly distributed inside the drying chamber 1.

[0025] This invention uses a distribution pipe connected to the hot air pipe to ensure that the hot air is evenly distributed in the drying chamber. The downward-sloping air outlets prevent the hot air from directly spraying onto the honeycomb paper, thus avoiding the heat from concentrating at a single point on the honeycomb paper.

[0026] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
