Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production, and more specifically, to a drying device for composite nonwoven fabrics. Background Technology

[0002] After impregnation, composite nonwoven fabrics need to be dried, and existing drying methods mostly use infrared light drying.

[0003] To meet the heat requirements for drying, infrared light needs to be installed on at least one side wall of the drying chamber. However, regardless of which side wall it is installed on, it is impossible to dry both the top and bottom sides of the nonwoven fabric at the same time. If the light energy is increased, one side of the nonwoven fabric will shrink, reducing the production quality of the nonwoven fabric. If infrared light is installed on the two inner walls of the chamber, it will result in a large waste of light and heat energy, increasing energy consumption and costs. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a drying device for composite nonwoven fabrics. The technical problem to be solved by this utility model is: how to improve the drying efficiency of the upper and lower sides of the nonwoven fabric with only the number of infrared lamps on one side wall.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for composite nonwoven fabric, comprising a drying chamber assembly, wherein the nonwoven fabric passes through the drying chamber assembly and can move within the drying chamber assembly; a drying lamp assembly, obliquely installed at one location inside the drying chamber assembly; and a light reflecting assembly, obliquely installed at another location inside the drying chamber assembly, wherein the drying lamp assembly and the light reflecting assembly are arranged diagonally; wherein, part of the light emitted by the drying lamp assembly illuminates the upper layer of the nonwoven fabric located inside the drying chamber assembly, and part of the light shines downward from the side of the nonwoven fabric onto the light reflecting assembly, and after being reflected by a mirror, illuminates the lower layer of the nonwoven fabric.

[0006] In a preferred embodiment, the drying lamp assembly includes a lamp holder and a lamp body, the lamp body being detachably connected to the lamp holder, the lamp holder being either fixedly or rotatably connected to the drying chamber assembly, and the lamp body being electrically connected to an external controller.

[0007] In a preferred embodiment, the light reflection assembly includes a frame and a mirror body, the reflective surface of the mirror body being a mirror surface, and the frame being either fixedly or rotatably connected to the drying oven assembly.

[0008] In a preferred embodiment, the mirror surface is a plane.

[0009] In a preferred embodiment, the mirror surface is convex.

[0010] In a preferred embodiment, the drying box assembly includes a box body, a passageway, and a shelf. Passageways are provided on both symmetrical surfaces of the box body, and a shelf is placed between the passageways to support the non-woven fabric entering and exiting through the corresponding passageways.

[0011] In a preferred embodiment, a bending plate is provided on the side of the passageway closest to the box body.

[0012] In a preferred embodiment, slots are provided at both ends of the shelf, and the slots are engaged with the bending plate.

[0013] In a preferred embodiment, an opening and closing door panel is rotatably connected to the outer side of the housing. When the opening and closing door panel is located at one of the path endpoints, the opening and closing door panel is closed and abuts against the outside of the passageway. When the opening and closing door panel is located at the other path endpoint, the opening and closing door panel is open and coplanar with the bottom surface of the passageway.

[0014] In a preferred embodiment, an exhaust system is connected to the bottom of the housing.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By allowing part of the light emitted by the drying lamps to illuminate the upper layer of the nonwoven fabric located inside the drying chamber, and another part of the light to shine downwards from the side of the nonwoven fabric onto the light reflector, and then shine onto the lower layer of the nonwoven fabric after being reflected by the mirror, the drying efficiency of the composite nonwoven fabric can be improved by adjusting the angle of the light without changing the original number of drying lamps.

[0027] Example

[0028] like Figures 1-4 A drying device for composite nonwoven fabrics includes a drying box assembly 10, a drying lamp assembly 20, and a light reflecting assembly 30. The drying box assembly 10 is a box structure made of sheet metal. The drying lamp assembly 20 and the light reflecting assembly 30 are installed inside the drying box assembly 10 in a diagonal arrangement.

[0029] The drying chamber assembly 10 includes a chamber body 11, a passageway 12, a shelf 13, a bending plate 14, and an opening and closing door panel 15. Sheet metal parts are assembled to form a closed chamber structure to form the chamber body 11. Passageways 12 are provided on both sides of the chamber body 11 to allow non-woven fabric to pass through. A shelf 13 is provided between the two passageways 12 to support the non-woven fabric flat inside the chamber body 11, so that the non-woven fabric can be spread out inside the drying chamber assembly 10 for uniform heating.

[0030] It is known that an insulation layer can be added to the inner wall of the box 11 according to the user's design.

[0031] Preferably, the width of the through-hole 12 is twice the width of the non-woven fabric, so that the non-woven fabric can pass through the through-hole 12 and move to a position on the shelf 13, so that part of the light emitted by the drying lamp assembly 20 falls on the non-woven fabric, and the other part falls on the light reflection assembly 30 and then falls on the non-woven fabric again.

[0032] Preferably, an opening and closing door panel 15 is rotatably connected to the outer wall of the housing 11. When the opening and closing door panel 15 is fully closed, it is against the outside of the passage 12. When the opening and closing door panel 15 is fully open, it is coplanar with the bottom surface of the passage 12, so as to close the passage 12 in the preheating environment and ensure that the temperature inside the housing 11 rises rapidly. The unfolded opening and closing door panel 15 can also guide the non-woven fabric into the passage 12, reducing the probability of wrinkles appearing on the edge of the passage 12.

[0033] Preferably, during the sheet metal processing, a designated position of the housing 11 is stamped, causing the bending plate 14 to bend. The space exposed after the bending plate 14 is bent is the passageway 12. After bending, the bending plate 14 can be aligned with the fully opened large hinged door panel 15 to form a guide surface on both the inner and outer sides of the passageway 12.

[0034] Preferably, the shelf 13 has slots at both ends, and the shelf 13 can be fixed by the engagement between the slots and the bending plate 14.

[0035] Preferably, in order to ensure the stability of the shelf 13 connected to the bending plate 14, the bending plate 14 is made of sheet metal with a thickness greater than 8mm, and the shelf 13 is made of lightweight high-temperature resistant composite material, such as carbon fiber reinforced carbon aerogel composite material. Since the temperature resistance and cost of such materials are different and common, this embodiment does not limit them.

[0036] The above-mentioned drying box assembly 10 has a simple design structure and is easy to manufacture.

[0037] like Figure 5 and Figure 6 The thick solid lines can be considered as non-woven fabric. The drying lamp assembly 20 is installed at the upper diagonal end of the housing 11, while the light reflecting assembly 30 is arranged diagonally opposite the drying lamp assembly 20 at the lower diagonal end of the housing 11. In this way, part of the light emitted from the drying lamp assembly 20 illuminates the upper surface of the non-woven fabric, while part is reflected by the light reflecting assembly 30 to the lower surface of the non-woven fabric. This changes the light path through specular reflection, without changing the number of infrared lamps, and guides some light energy to both the upper and lower surfaces of the non-woven fabric, thereby improving drying efficiency.

[0038] The drying lamp assembly 20 includes a lamp holder and a lamp body. The lamp body is a commercially available lamp assembly with a lamp tube that emits infrared light. Several lamp bodies are connected to the lamp holder by a detachable connection method, which is existing technology and will not be described in detail. The lamp holder is connected to the side wall of the housing 11.

[0039] Specifically, one end of the lamp holder is rotatably connected to the housing 11 via a threaded joint, with a locking nut at the connection point. After the position is adjusted, the locking nut is tightened onto the threaded joint to fix the lamp holder inside the housing 11. The other end of the lamp holder is connected to the housing 11 via a pin. On the side wall of the housing 11, several pin holes are formed with the axis of the locking nut as the center and the width of the lamp holder as the radius. When the lamp holder moves to the corresponding pin hole, the pin is simultaneously inserted into the pin hole and the hole pre-drilled in the lamp holder to further define the position of the lamp holder. The remaining pin holes on the side wall of the housing 11 are plugged when not in use to reduce heat loss.

[0040] The light reflection assembly 30 includes a frame and a mirror body. The mirror body is a commercially available mirror that is heat-resistant and reflects light in a mirror-like manner. The mirror body is fixed to the frame. Of course, the frame can also be connected to the housing 11 by a fixed connection or a rotating connection.

[0041] The fixed connection method is relatively simple. After adjusting the reflection angle of the mirror, the mirror frame can be fixed to the housing 11 with bolts and fasteners.

[0042] For a rotating connection, the connection method on both sides of the frame needs to be considered. In this embodiment, the connection between the housing 11 and the lamp holder is the same. Specifically, one end of the frame is rotatably connected to the housing 11 via a threaded joint, and a locking nut is provided at the center of the connection. After the position is adjusted, tightening the locking nut will fix the lamp holder inside the housing 11. The other end of the frame is connected to the housing 11 via a pin. On the side wall of the housing 11, several pin holes are opened with the axis of the locking nut as the center and the width of the frame as the radius. When the lamp holder moves to the corresponding pin hole, the pin is inserted into both the pin hole and the hole pre-drilled in the frame to further define the position of the lamp holder. The remaining pin holes on the side wall of the housing 11 are plugged when not in use to reduce heat loss.

[0043] Of course, users can also use other connection methods to determine the optical path of the drying lamp group 20 and the reflection path of the light reflection group 30, which is not limited in this embodiment.

[0044] Furthermore, the mirror body of the light reflecting group 30 can also be a convex mirror to expand the radiation range after the light path is reflected, which is suitable for application scenarios where the incident light range is small but the required reflected light range is large.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

[0046] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
