Description

Technical Field

[0001] This utility model relates to the field of glass fiber composite material processing technology, specifically to a heat treatment device for glass fiber composite materials. Background Technology

[0002] Glass fiber composites are materials made by combining glass fibers with matrix materials such as resins. Glass fiber composites possess properties such as lightweight, high strength, corrosion resistance, and insulation, and are widely used in automotive manufacturing, aerospace, and construction. However, glass fibers also have some limitations. To overcome these limitations and endow them with superior overall performance, thus expanding their application areas, surface treatment is a commonly used glass fiber application technology worldwide. Glass fiber surface treatment is generally divided into two categories: one is heat treatment, also known as thermal cleaning. This involves using heating methods to remove the paraffin-based textile sizing agent adhering to the surface of the glass fiber during the forming and processing, to meet the requirements of subsequent processing and product performance. The equipment used for heat treatment is called a heat treatment furnace.

[0003] According to a public announcement (Announcement No.: CN222086686U), a heat treatment device for glass fiber composite materials includes a heating furnace. The heating furnace has a heating chamber inside, and heating components are fixedly installed on the inner wall of the furnace. A platform is fixedly installed at the bottom of the furnace, and a heating table is slidably connected to the top of the platform. A hot air blower is fixedly installed on the top of the furnace. Several flow guides are provided on the inner wall of the furnace. A three-way pipe is fixedly installed on the outer surface of the furnace, and the outlet ends of the three-way pipes are all connected to the flow guides. A first return pipe and a second return pipe are fixedly installed on the top of the three-way pipes, and a return component is fixedly installed at one end of each of the first and second return pipes.

[0004] However, in actual use, when the hot air in the heating furnace enters the tee pipe through several guide ports inside the heating furnace, and then passes through the first and second return pipes, it is transported into the heating furnace by the induced draft fans fixed to both sides of the heating furnace through the air supply pipe and through the through hole. Since all the above pipes are outside the heating furnace, they are easily affected by the external temperature, resulting in uneven temperature of the hot air re-entering the heating furnace, which leads to poor heat recovery and reduced heat recycling efficiency. In view of this, we propose a heat treatment device for glass fiber composite materials. Utility Model Content

[0017] 2. In this heat treatment equipment for glass fiber composite materials, after the heat recovery of the hot air is fully mixed evenly by the reflux mechanism, the hot air rushes upward and enters the heat equalization mechanism through the air inlet. The rising hot air drives the second fan blade to rotate. Through the rotation of the second fan blade, the recovered hot air is evenly distributed to multiple sets of air jet nozzles set in the heat equalization mechanism. The hot air sprayed out by the air jet nozzles achieves a more uniform effect. Attached Figure Description

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a heat treatment device for glass fiber composite materials, including a main body 1, a support frame 109 fixedly connected to the upper surface of the main body 1, a base 102 fixedly connected to the lower surface of the main body 1, a guide rail groove 107 provided inside the base 102, a support plate 103 provided at one end of the main body 1, a shelf 106 fixedly connected to the upper surface of the support plate 103, and a stop fixedly connected to one end of the shelf 106. The lower surface of the support plate 103 is fixedly connected to the movable toothed plate 104, the baffle 105 is provided with a buckle 108, and the outer surface of the main body 1 is provided with a slot 101. The main body 1 is characterized by having a reflux mechanism 3 inside, which includes: a second motor 301, a secondary heating pipe 302, an air guide pipe 303, an air intake 304, an air outlet pipe 305, a first fan blade 306, a reflux box 307, an air outlet 308, an air inlet 309, and a secondary heating plate 310.

[0025] In one embodiment of this utility model, the suction machine 304 is fixedly connected to the outer wall of the main body 1 at the end away from the support plate 103. An air outlet 305 is fixedly connected to the input end of the suction machine 304, and an air guide 303 is fixedly connected to the output end of the suction machine 304. A return box 307 is fixedly connected to the upper surface of the base 102. A second motor 301 is fixedly connected to the lower inner surface of the return box 307. A fan blade 306 is fixedly connected to the output end of the second motor 301. A secondary heating plate 310 is fixedly installed on the inner side wall of the return box 307, and a secondary heating pipe 302 is disposed inside the secondary heating plate 310. An air inlet 309 is disposed on the side of the return box 307, and an air outlet 308 is disposed on the inner side of the main body 1. When the suction machine 304 is started... The air outlet 305 draws in hot air from the main body 1 through the air outlet 308. After passing through the air outlet 305, the air intake 304, and the air guide 303, the air enters the return box 307 through the air inlet 309. Through the high-speed rotation of the second motor 301, the fan blade 306 rapidly fuses the introduced hot air with the heat generated by the secondary heating plate 310 and the secondary heating pipe 302 in the return box 307, so that the temperature of the hot air in the return box 307 rises evenly. With the help of multiple sets of uniform heat distribution mechanisms 4 evenly fixedly connected to the upper surface of the return box 307, and multiple sets of air nozzles 401 arranged in a circumferential array on the outer surface of the nozzle body 406, the heated hot air is evenly sprayed onto the shelf 106 through the multiple sets of air nozzles 401, improving the working efficiency of this equipment.

[0026] In one embodiment of this utility model, the inner upper surface of the main body 1 is provided with an opening corresponding to the outlet of the hot air blower 201. Two sets of hot air blowers 201 and motor 203 are provided and fixedly connected to the upper surface of the main body 1. Two sets of support plates 103 are provided and fixedly connected to both sides of the lower surface of the shelf 106. Buckles 108 are located in pairs on both sides of the baffle 105, and the number of slots 101 is the same as the number of buckles 108. The length of the buckles 108 is the same as the internal length of the slots 101. By providing symmetrical limiting buckles 108 on both sides of the baffle 105, the shelf 106... After the movable baffle 105 moves synchronously, it cooperates with the slot 101 on the outer surface of the main body 1 to limit the closed position of the baffle 105. At the same time, it also limits the fixed position of the baffle 105, preventing the baffle 105 from moving excessively and affecting the sealing effect on the main body 1. Furthermore, the baffle 105 can achieve a self-sealing effect by sealing the entrance of the main body 1, preventing the heat inside the main body 1 from being lost. In addition, in specific applications, after heating is completed, the placement plate 106 moves in the opposite direction, driving the baffle 105 to move in the opposite direction, which in turn drives the buckle 108 to move in the opposite direction and disengage from the inside of the slot 101 to release the restriction on the baffle 105.

[0027] In this embodiment of the utility model, support plates 103 are fixedly installed on both sides of the lower surface of the shelf 106. A movable toothed plate 104 is fixedly connected to the lower surface of the support plate 103. A motor 5 is provided on the side wall of the base 102. A rotating gear 501 is fixedly installed at the output end of the motor 5. The rotating gear 501 meshes with the movable toothed plate 104. When the motor 5 is started, the motor 5 drives the rotating gear 501 to rotate. The movable toothed plate 104 fixedly installed at the bottom of the support plate 103 is driven by the rotating gear 501 to move towards the main body 1. After the heat treatment is completed, the shelf 106 can be moved out of the main body 1 by the reverse rotation of the motor 5, thereby reducing the danger of manual operation.

[0028] In this invention, during use, the glass fiber composite material to be processed is placed on the shelf 106. The rotation of the motor 305, fixedly connected to the side wall of the base 102, in conjunction with the moving toothed plate 104 fixedly connected to the bottom of the support plate 103, pushes the shelf 106 containing the glass fiber composite material into the main body 1. The heating mechanism 2 then starts working. The activation of the motor 203, fixedly connected to the side of the support frame 109, drives the hot air blower 201 to draw in air from the suction cylinder 202 for heating. Combined with the heating from the main heating plate 204 and the main heating pipe 205, the glass fiber composite material placed on the shelf 106 is heated. At this time, the suction machine 304 starts working, drawing hot air from the main body 1 into the air outlet 305 through the air outlet 308. The gas in the air outlet 305 enters the air guide pipe 303 through the suction machine 304 and is then sprayed into the main body 1 through the air inlet 402. In the return box 307, the high-speed rotation of the second motor 301 drives the first fan blade 306 to rotate at high speed. In conjunction with the secondary heating tube 302 and the secondary heating plate 310 set in the return mechanism 3, the heat emitted by the secondary heating tube 302 and the secondary heating plate 310 is rotated and fused with the gas entering the return box 307. The fused and heated gas enters the nozzle body 406 through the air inlet 402 set in the heat equalization mechanism 4. The high-speed hot air drives the second fan blade 404, which is fixedly connected to the outer surface of the bearing 405, to rotate. The inner surface of the bearing 405 is fixedly connected to the outer surface of the fixing rod 403. The fixing rod 403 is fixedly connected to the inner upper surface of the nozzle body 406. The rotation of the second fan blade 404 further mixes the hot air evenly and sprays the hot air into the body 1 through multiple sets of nozzle bodies 406, thereby improving the heat recycling efficiency and enhancing the heat recovery effect.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
