Description

Technical Field

[0001] This utility model relates to the field of fiber fabric technology, and in particular to a shaping and drying tunnel. Background Technology

[0002] Carbon fiber, as an advanced composite material, has been widely used in many fields such as aerospace, nuclear energy equipment, and transportation.

[0003] In different application fields, carbon fiber fabrics often employ different processes to meet the production requirements. For example, the surface of the fabric fibers is usually coated with a sizing agent. In some production fields, the presence of this sizing agent often affects the resin impregnation effect. In order to improve the impregnation effect of the fabric fibers and resin in the later stage, the sizing agent on the surface of the fabric fibers must be removed in the early stage before spraying chemical powder to adhere to the fabric and harden on the surface to form a shaped fabric and prevent the fiber bundles from loosening.

[0004] Heating is typically used to remove sizing agents from fabric surfaces, and it is also common to heat chemical powders after they are sprayed to melt them. However, fabric fibers are usually in roll form initially. Existing heating devices, due to their structural limitations, require the fabric fibers to be cut before heating them individually. This is not only inefficient, but the heating process also affects the cutting dimensions, requiring subsequent dimensional adjustments to meet application requirements. This process is complex and results in unnecessary material waste.

[0005] Therefore, it is necessary to provide a drying tunnel that can continuously heat the fiber fabric in roll form during continuous conveying, and then cut it as needed after the heating dimensions have stabilized. Utility Model Content

[0006] To address the aforementioned issues, this application provides a structurally sound shaping and drying tunnel that can heat continuously conveyed materials, particularly suitable for heating fiber fabrics in roll form, thereby improving and ensuring heating efficiency, simplifying processes, and saving materials.

[0007] The technical solution adopted in this utility model is as follows: A shaping drying tunnel includes a frame on which an oven is supported. The oven has openings on its front and rear sides for material conveying. The material is driven by a supporting conveying mechanism to enter the oven through the front opening and exit through the rear opening. Multiple heating tubes are arranged at intervals along the conveying direction inside the oven. The oven includes an upper chamber and a lower chamber, which are rotatably connected at their edges. The upper chamber is driven by an opening and closing mechanism to open upward or close downward relative to the lower chamber.

[0008] As a further improvement to the above technical solution: The upper and lower housings have a stepped structure with an inner higher and outer lower edge between their left and right edges, and a sealing element is press-fitted at the gap.

[0009] Multiple sealing grooves are installed at intervals from the inside to the outside on the top surface of the lower housing located at the spacing. The sealing element is installed in the sealing groove, and the upper end of the sealing element extends out of the sealing groove and is pressed in by the bottom surface of the upper housing.

[0010] The heating tubes are arranged in two sets at intervals along the conveying direction, with the two sets of heating tubes located above and below the material, respectively; radiant plates are arranged along the conveying direction between the upper set of heating tubes and the top surface of the material, and between the lower set of heating tubes and the bottom surface of the material, respectively.

[0011] The supporting conveying mechanism includes multiple rollers spaced apart along the conveying direction, with both ends of the rollers rotatably mounted to the oven or frame; a V-groove is provided at the end of the conveying section of each roller, and a traction rope is provided around the V-groove of each roller; the end of each roller extends out of the oven or frame and is fitted with a drive wheel, and a transmission component is connected between adjacent drive wheels, so that the rollers are driven to rotate synchronously by external rotational power through the drive wheels for conveying.

[0012] Asbestos sheets are pressed between the roller end bearing assembly located in the oven and the outer wall of the oven.

[0013] It also includes an exhaust gas pipe connected to the top surface of the oven, and a suction hood connected to the exhaust gas pipe is fitted to the front or rear side of the oven; the exhaust gas pipe is connected to the exhaust gas treatment device; the front and rear openings of the oven are respectively equipped with lifting doors, and the opening height can be adjusted by moving the lifting doors up and down.

[0014] The opening and closing mechanism includes a linear drive power source. The bottom end of the linear drive power source is rotatably mounted on the lower support of the frame, and the upward-facing output end of the linear drive power source is rotatably mounted on the upper support. The upper support is mounted on the upper housing.

[0015] It also includes a temperature control component. The oven is set with two or more temperature zones along the conveying direction. The temperature control component includes a corresponding number of probe groups for each temperature zone. Each probe group includes temperature measuring probes located on the left and right sides and a temperature control probe located in the middle.

[0016] A cooling mechanism is also provided on the frame located at the rear of the oven in the material output direction. The cooling mechanism includes one or more air storage pipes. Multiple air nozzles connected to an external air source are arranged at intervals along the width of the frame on the air storage pipes, and air is blown towards the material from the air nozzles. The air storage pipes are movably installed relative to the frame to adjust the blowing direction of the air nozzles or are fixedly installed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention continuously conveys materials through a support conveying mechanism while heating the materials passing through it in an oven. It is particularly suitable for heating fiber fabrics in roll form, improving and ensuring heating efficiency, simplifying processes, and saving materials. This utility model also has the following advantages: By setting the oven as an upper and lower chamber with a separate upper and lower chamber, and using an opening and closing mechanism to switch the opening and closing of the upper chamber, it is convenient to maintain and clean the inside of the oven. By setting up a radiant plate between the heating tube and the material, the heat from the heating tube is evenly distributed by the radiant plate, which helps to ensure that the material is heated evenly. By attaching traction ropes to the ends of the rollers supporting the conveying mechanism, the material can be tied to the traction ropes on both sides at the oven inlet during the initial material feeding. The material is then pulled to the oven outlet by the roller drive, which facilitates operation. Attached Figure Description

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a shaping drying tunnel in this embodiment includes a frame 1, on which an oven 4 is supported and installed. The oven 4 has openings on its front and rear sides that are open to the inside and outside for material conveying. The material is driven by the supporting conveying mechanism 2 to enter the oven 4 through the front opening and exit the oven 4 through the rear opening. Multiple heating tubes 8 are arranged at intervals along the conveying direction inside the oven 4. The oven 4 includes an upper box body 41 and a lower box body 42. The edges of the upper box body 41 and the lower box body 42 are rotatably connected. The upper box body 41 is driven by the opening and closing mechanism 3 to open upward or close downward relative to the lower box body 42.

[0029] In this embodiment, while the material is continuously conveyed by the support conveyor 2, the oven 4 heats the material that passes through it, which is especially suitable for the heating needs of fiber fabrics in roll form.

[0030] In this embodiment, the oven 4 is configured as an upper chamber 41 and a lower chamber 42, and the opening and closing of the upper chamber 41 is switched by the opening and closing mechanism 3, which facilitates the maintenance and cleaning of the interior of the oven 4.

[0031] In this embodiment, the rotatable connection between the upper box 41 and the lower box 42 can be made of stainless steel hinges, with multiple hinges arranged along the conveying direction; other conventional rotatable structures can also be used.

[0032] The upper housing 41 and the lower housing 42 are close to each other, and the left and right edges form a stepped structure with an inner high and an outer low, with a gap of 40. A sealing element 43 is press-fitted at the gap of 40 to effectively ensure the sealing effect after closing and to ensure the heating effect.

[0033] In this embodiment, the upper box 41 and the lower box 42 are each formed independently. They are both formed by combining an outer cold-formed plate (high-temperature electrostatic powder coating) with an inner stainless steel plate to form a cavity, and the cavity is filled with aluminum silicate cotton. In one embodiment, a 2mm cold-formed plate, a 1.2mm stainless steel plate, and 200mm aluminum silicate cotton can be used.

[0034] The top surface of the lower housing 42, located at a spacing of 40, is provided with multiple sealing grooves from the inside to the outside. The sealing element 43 is disposed in the sealing groove, and the upper end of the sealing element 43 extends out of the sealing groove and is pressed into the bottom surface of the upper housing 41.

[0035] In this embodiment, heating the sealing groove avoids damage to the shape of the lower housing 42, effectively ensuring the integrity of the lower housing 42's shape while guaranteeing its sealing performance.

[0036] In practice, the sealing groove can be made of materials with heat resistance and other properties, such as stainless steel, depending on the actual needs.

[0037] Two sets of heating tubes 8 are arranged at intervals along the conveying direction, with the two sets of heating tubes 8 located above and below the material respectively; radiation plates 81 are arranged along the conveying direction between the upper set of heating tubes 8 and the top surface of the material, and between the lower set of heating tubes 8 and the bottom surface of the material respectively.

[0038] In this embodiment, the radiant plate 81 between the heating tube 8 and the material is arranged to even out the heat from the heating tube 8. Combined with the heating arrangement on the upper and lower sides, this helps to ensure the consistency of heat inside the oven 4 and ensures that the material is heated evenly.

[0039] In actual operation, the heating tube 8 can be installed by passing both ends through the wall of the oven 4, so that the area of ​​the heating tube 8 inside the oven 4 constitutes the heating section for heating.

[0040] like Figure 5 and Figure 6 As shown, the supporting conveying mechanism 2 includes multiple rollers 21 spaced apart along the conveying direction. The two ends of the rollers 21 are rotatably mounted to the oven 4 or the frame 1. A V-groove 211 is provided at the end of the conveying section of each roller 21, and a traction rope 22 is provided around the V-groove 211 of each roller 21. The end of each roller 21 extends out of the oven 4 or the frame 1 and is fitted with a drive wheel 24. A transmission component is connected between adjacent drive wheels 24. The external rotational power drives each roller 21 to rotate synchronously for conveying via the drive wheels 24.

[0041] In this embodiment, by winding traction ropes 22 around the ends of the rollers 21 of the support conveying mechanism 2, when the material is first fed, the material can be tied to the traction ropes 22 on both sides at the feed inlet of the oven 4, and the material can be pulled to the discharge outlet of the oven 4 by the transmission of the rollers 21, which is convenient for operation.

[0042] In this embodiment, an external rotational power source, such as a motor, can drive one of the transmission wheels 24 to rotate via the drive wheel 25, thereby achieving synchronous rotation of each roller 21.

[0043] In this embodiment, the drive wheel 25 and the transmission wheel 24 can be sprockets, which, together with a chain, enable power transmission between the drive wheel 25 and the transmission wheel 24, as well as between adjacent transmission wheels 24.

[0044] An asbestos sheet 20 is pressed between the bearing assembly 23 at the end of the roller 21 located in the oven 4 and the outer wall of the oven 4 for heat insulation, so as to extend the service life of the bearing assembly 23.

[0045] It also includes an exhaust pipe 5 connected to the top surface of the oven 4, and a suction hood 51 connected to the exhaust pipe 5 installed on the front or rear side of the oven 4; the exhaust pipe 5 is connected to the exhaust gas treatment device 52; and lifting doors 44 are installed at the front and rear openings of the oven 4, and the opening height is adjusted by moving the lifting doors 44 up and down.

[0046] In this embodiment, a step platform 7 that can be climbed can also be set on the outside of the shaping drying tunnel as needed. The exhaust gas treatment device 52 and the like can be arranged on the step platform 7 to support and be close to the drying tunnel, and also to facilitate climbing and maintenance operations.

[0047] In this embodiment, during the use of the drying tunnel, the lifting door 44 can be lowered so that its lower edge is close to the surface of the fabric but does not affect its free transport, thereby reducing the loss of heat in the drying oven 4 and ensuring the heating effect.

[0048] The opening and closing mechanism 3 includes a linear drive power source. The bottom end of the linear drive power source is rotatably mounted on the lower support 32 of the frame 1, and the upward output end of the linear drive power source is rotatably mounted on the upper support 31. The upper support 31 is mounted on the upper housing 41.

[0049] In this embodiment, the linear drive power can be selected from conventional power components such as electric cylinders, depending on the requirements.

[0050] Of course, in actual operation, it is necessary to first disconnect the connecting pipe between the exhaust gas discharge pipe 5 at the top of the upper box 41 and the exhaust gas treatment device 52, for example... Figure 1 The connecting segment at the dotted line is then used to open the upper box 41 upwards relative to the lower box 42.

[0051] In this embodiment, the opening angle of the upper housing 41 can be set according to actual needs, such as within 20°, to meet actual use requirements.

[0052] It also includes a temperature control component 6. The oven 4 is set with two or more temperature zones along the conveying direction. The temperature control component 6 includes a corresponding number of probe groups for each temperature zone. Each probe group includes temperature measuring probes located on the left and right sides and a temperature control probe located in the middle.

[0053] In this embodiment, during use, the temperature value can be detected by the central temperature control probe for real-time control and adjustment of the power of the heating tubes 8 in each temperature zone, while the temperature probe performs temperature correction to ensure uniform and consistent temperature in each temperature zone.

[0054] In one embodiment, three temperature zones are provided: low, medium, and high.

[0055] In one embodiment, the probe can use a type K thermocouple for temperature measurement.

[0056] Of course, in actual operation, alarm lights and other facilities can also be installed to provide warnings and reminders when the temperature is high or too high.

[0057] like Figure 7 and Figure 8 As shown, a cooling mechanism 9 is also provided on the frame 1 located on the rear side of the oven 4 in the material output direction. The cooling mechanism 9 includes one or more air storage pipes 91. Multiple air nozzles 92 connected to an external air source are provided at intervals along the width direction of the frame 1 on the air storage pipes 91. Air is blown towards the material from the air nozzles 92. The air storage pipes 91 are movably installed relative to the frame 1 to adjust the blowing direction of the air nozzles 92 or are fixedly installed.

[0058] In this embodiment, the fabric is cooled by blowing air onto the fabric surface through the cooling mechanism 9 at the outlet of the oven 4.

[0059] In this embodiment, a bracket 94 can be installed on the frame 1. The end of the air storage pipe 91 extends toward the bracket 94 to form an extension wall 93. An external shaft pin passes through the circular hole 932 of the extension wall 93 and is fitted onto the bracket 94. At the same time, an arc-shaped groove 931 is opened on the extension wall 93 concentric with the circular hole 932. An external fastener passes through the arc-shaped groove 931 and is fitted onto the bracket 94. The arc-shaped groove 931 allows the air storage pipe 91 to swing relative to the frame 1 with the circular hole 932 as the center to adjust the blowing angle of the nozzle 92, and then lock it after adjustment.

[0060] This invention can heat continuously conveyed materials, and is especially suitable for heating fiber fabrics in roll form, improving and ensuring heating efficiency, helping to simplify processes and save materials.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
