[0034] Embodiment 1

[0035] A uniform drying device for glass fiber production includes a drying cylinder 1, a support frame 2, a sealing cover 3, a positioning plate 4, a heating module 5, a positioning mechanism 6 and a stirring mechanism 7. Please refer to Figures 1-5 As shown, support frames 2 are symmetrically and fixedly connected to the front and rear of the outer bottom of the drying cylinder 1. The upper right side of the drying cylinder 1 is rotatably connected with a sealing cover 3. The sealing cover 3 is in contact with the open end of the drying cylinder 1. A heating module 5 is arranged in the middle of the inner bottom of the drying cylinder 1. When the heating module 5 is started, the heating module 5 can dry the glass fiber. The middle right side of the drying cylinder 1 is rotatably connected with a positioning plate 4. The positioning plate 4 is in contact with the sealing cover 3. The positioning plate 4 can limit the sealing cover 3. A positioning mechanism 6 is arranged between the drying cylinder 1 and the sealing cover 3. A stirring mechanism 7 is arranged on the positioning mechanism 6. When the stirring mechanism 7 operates, the stirring mechanism 7 can stir the glass fiber. The positioning mechanism 6 is used to drive the stirring mechanism 7 to move.

[0036] It also includes a rubber plate 21. Please refer to Figure 1 and Figure 2 As shown, rubber plates 21 are fixedly connected to the bottoms of the front and rear support frames 2.

[0037] The positioning mechanism 6 includes a rotating shaft 61, a rope pulley 62, a soft rope 63, a lifting vertical plate 64 and a positioning spring 65. Please refer toFigure 3 and Figure 4 As shown in Figure 4 , lifting vertical plates 64 are slidably penetrated through both the front and rear sides of the drying cylinder 1. When the lifting vertical plates 64 move, the lifting vertical plates 64 can drive the stirring mechanism 7 to move. Between the left and right sides of the front and rear lifting vertical plates 64 and the inner side of the drying cylinder 1, positioning springs 65 are connected. In the middle of the upper parts of the front and rear outer side surfaces of the drying cylinder 1, rotating shafts 61 are rotatably connected. Between the middle parts of the front and rear rotating shafts 61 and the shaft of the sealing cover 3, synchronous belt drives are provided. On the inner sides of the front and rear rotating shafts 61, rope wheels 62 are fixedly sleeved. On the front and rear rope wheels 62, two soft ropes 63 are wound. The two front soft ropes 63 are fixedly connected to the front lifting vertical plate 64, and the two rear soft ropes 63 are fixedly connected to the rear lifting vertical plate 64.

[0038] The stirring mechanism 7 includes a servo motor 71, a driving shaft 72, and a stirring frame 73. Please refer to Figure 3 and Figure 5 As shown in Figure 5 , the driving shaft 72 is rotatably penetrated through the middle parts of the front and rear lifting vertical plates 64. In the middle of the driving shaft 72, the stirring frame 73 is fixedly sleeved. When the stirring frame 73 rotates, the stirring frame 73 can stir the glass fiber. In the middle of the front side surface of the front lifting vertical plate 64, the servo motor 71 is installed by means of bolt connection. The servo motor 71 is fixedly connected to the front end of the driving shaft 72.

[0039] First, pull the sealing cover 3 to swing upward to open it, and then pull the positioning plate 4 to swing downward to open it. The upward swing of the sealing cover 3 drives the positioning mechanism 6 to operate. The operation of the positioning mechanism 6 drives the stirring mechanism 7 to move upward to a suitable position, and then an appropriate amount of glass fiber can be poured into the drying cylinder 1. Then, pull the positioning plate 4 to swing upward to reset it, and pull the sealing cover 3 to swing downward to reset it. The reset of the sealing cover 3 drives the positioning mechanism 6 to reset, and the reset of the positioning mechanism 6 drives the stirring mechanism 7 to move downward to reset. The stirring mechanism 7 contacts the glass fiber. Start the heating module 5, and the heating module 5 dries the glass fiber. Then start the stirring mechanism 7, and the operation of the stirring mechanism 7 stirs the glass fiber, so that the glass fiber is evenly dried. Due to the effect of the rubber plate 21, the device can be placed more stably. When the glass fiber is dried, turn off the heating module 5 and the stirring mechanism 7. Pull the sealing cover 3 to swing upward to open it, and the stirring mechanism 7 will move upward to disengage from the glass fiber. The upward movement of the stirring mechanism 7 increases the material taking space, and then the glass fiber can be conveniently taken out, improving the material taking efficiency. When all the glass fiber is taken out, pull the sealing cover 3 to swing downward to reset and close it, and the stirring mechanism 7 will move downward to reset.

[0040] When the sealing cover 3 swings upward to open, the sealing cover 3 swings upward to drive the front and rear side rotating shafts 61 to reverse through the synchronous belt drive. The reverse rotation of the front and rear side rotating shafts 61 drives the front and rear side rope wheels 62 to reverse. The reverse rotation of the front and rear side rope wheels 62 winds up the front and rear side flexible ropes 63. The winding of the front and rear side flexible ropes 63 drives the front and rear side lifting vertical plates 64 to move upward. The positioning spring 65 is compressed. The upward movement of the front and rear side lifting vertical plates 64 drives the stirring mechanism 7 to move upward. The upward movement of the stirring mechanism 7 disengages it from the glass fiber, thereby increasing the material taking space. Then the glass fiber can be taken out from the drying cylinder 1. After all the glass fiber is taken out, pull the sealing cover 3 to swing downward to reset. The downward swing reset of the sealing cover 3 drives the front and rear side rotating shafts 61 to rotate forward to reset through the synchronous belt drive. The forward rotation reset of the front and rear side rotating shafts 61 drives the front and rear side rope wheels 62 to rotate forward to reset. The forward rotation reset of the front and rear side rope wheels 62 relaxes the front and rear side flexible ropes 63. Due to the action of the positioning spring 65, the downward movement reset of the front and rear side lifting vertical plates 64 drives the stirring mechanism 7 to move downward to reset.

[0041] When the sealing cover 3 swings upward to open, the front and rear side lifting vertical plates 64 move upward to drive the drive shaft 72 to move upward. The upward movement of the drive shaft 72 drives the stirring frame 73 to move upward to a suitable position. Then, after the glass fiber is placed, pull the sealing cover 3 to swing downward to reset. The downward movement reset of the front and rear side lifting vertical plates 64 drives the drive shaft 72 to move downward to reset. The reset of the drive shaft 72 drives the stirring frame 73 to move downward to reset. The stirring frame 73 contacts the glass fiber. Start the servo motor 71. The servo motor 71 drives the drive shaft 72 to rotate. The rotation of the drive shaft 72 drives the stirring frame 73 to rotate. The rotation of the stirring frame 73 agitates the glass fiber, so that the glass fiber is evenly dried. When the glass fiber is evenly dried, turn off the servo motor 71. The drive shaft 72 stops driving the stirring frame 73 to rotate. When the sealing cover 3 is opened again, the stirring frame 73 moves upward to disengage from the glass fiber, increasing the material taking space and facilitating the taking out of the glass fiber.

[0042] Embodiment 2

[0043] On the basis of Embodiment 1, there is also a material scattering mechanism 8. The material scattering mechanism 8 includes a bevel gear ring 81, bevel gears 82, a mounting shaft 83, a flexible rod frame 84 and a rotating rod 85. Please refer to Figures 6-8As shown in the figure, four rotating rods 85 are rotatably connected between the upper and lower sides of the stirring frame 73 and the drive shaft 72 at uniform intervals. Soft rod frames 84 are fixedly connected to all the rotating rods 85. When the soft rod frames 84 rotate, the soft rod frames 84 can disperse the glass fibers. On the front side of the drive shaft 72, mounting shafts 83 are symmetrically connected in the circumferential direction up and down. Conical gears 82 are fixedly sleeved on the outer ends of the upper and lower mounting shafts 83. Between the lower part of the upper mounting shaft 83 and the lower parts of the upper four rotating rods 85, and between the upper part of the lower mounting shaft 83 and the upper parts of the lower four rotating rods 85, synchronous belt drives are provided respectively. In the middle of the front side of the inner surface of the drying cylinder 1, a conical gear ring 81 is installed by means of bolt connection. The conical gear ring 81 meshes with the two conical gears 82. When the conical gears 82 rotate, the conical gear ring 81 can drive the conical gears 82 to rotate.

[0044] It further includes a sealing mechanism 9. The sealing mechanism 9 includes an acceleration gear disk 91, a driven gear 92, a transmission cross shaft 93, a positioning gear 94, an arc-shaped rack 95, a sealing plate 96 and a positioning frame 97. Please refer to Figure 6 , Figure 9 and Figure 10 As shown in the figure, positioning frames 97 are fixedly connected symmetrically in the front and back of the drying cylinder 1. An arc-shaped rack 95 is slidably sleeved between the front and back positioning frames 97. A sealing plate 96 is installed between the front and back arc-shaped racks 95 by means of welding connection. The sealing plate 96 contacts the drying cylinder 1 and the sealing cover 3. The sealing plate 96 can block the gap between the drying cylinder 1 and the sealing cover 3. Transmission cross shafts 93 are rotatably connected to the right parts of the front and back sides of the drying cylinder 1. Positioning gears 94 are fixedly sleeved on the inner ends of the front and back transmission cross shafts 93. The front and back positioning gears 94 mesh with the front and back arc-shaped racks 95 respectively. When the positioning gears 94 rotate, the positioning gears 94 can drive the arc-shaped racks 95 to move. Driven gears 92 are rotatably connected to the middle of the upper parts of the front and back outer surfaces of the drying cylinder 1. Synchronous belt drives are provided between the front and back driven gears 92 and the front and back transmission cross shafts 93 respectively. Acceleration gear disks 91 are fixedly sleeved on the outer ends of the front and back rotating shafts 61. The front and back acceleration gear disks 91 mesh with the front and back driven gears 92 respectively. When the acceleration gear disks 91 rotate, the acceleration gear disks 91 can drive the driven gears 92 to rotate quickly.

[0045] When the servo motor 71 starts, the drive shaft 72 rotates to drive the eight rotating rods 85 to rotate. The eight rotating rods 85 rotate to drive the eight soft rod holders 84 to rotate. The eight soft rod holders 84 rotate and contact the fiberglass. At the same time, the drive shaft 72 rotates to drive the two mounting shafts 83 to rotate. The two mounting shafts 83 rotate to drive the two bevel gears 82 to rotate. The two bevel gears 82 rotate through the bevel gear ring 81. The two bevel gears 82 rotate to drive the two mounting shafts 83 to rotate. The two mounting shafts 83 rotate to drive the eight rotating rods 85 to rotate through the synchronous belt drive. The eight rotating rods 85 rotate to drive the eight soft rod holders 84 to rotate. The eight soft rod holders 84 rotate to disperse the fiberglass. The dispersed fiberglass is dried. When the drying of the fiberglass is completed, the servo motor 71 is turned off. The drive shaft 72 stops driving the eight rotating rods 85 to rotate. The eight soft rod holders 84 stop rotating. And the drive shaft 72 also stops driving the two mounting shafts 83 to rotate. The two bevel gears 82 also stop rotating. The eight soft rod holders 84 also stop rotating. In this way, it prevents the fiberglass from caking and affecting the drying, thus ensuring the drying effect of the fiberglass.

[0046] When the sealing cover 3 swings upward to open, the front and rear side rotating shafts 61 reverse to drive the front and rear side acceleration gear discs 91 to reverse. The front and rear side acceleration gear discs 91 reverse to drive the front and rear side driven gears 92 to rotate forward. The front and rear side driven gears 92 rotate forward to drive the front and rear side transmission cross shafts 93 to rotate forward through the synchronous belt drive. The front and rear side transmission cross shafts 93 rotate forward to drive the front and rear side positioning gears 94 to rotate forward. The front and rear side positioning gears 94 rotate forward to drive the front and rear side arc-shaped racks 95 to swing downward. The front and rear side arc-shaped racks 95 swing downward to drive the sealing plate 96 to swing downward. The sealing plate 96 swings downward without blocking the gap between the sealing cover 3 and the drying cylinder 1. When the fiberglass is placed, the sealing cover 3 swings downward to reset. The front and rear side rotating shafts 61 rotate forward to reset to drive the front and rear side acceleration gear discs 91 to rotate forward to reset. The front and rear side acceleration gear discs 91 rotate forward to reset to drive the front and rear side driven gears 92 to reverse. That is, the front and rear side arc-shaped racks 95 drive the sealing plate 96 to swing upward to reset. The sealing plate 96 blocks the gap between the drying cylinder 1 and the sealing cover 3. In this way, it prevents foreign impurities from entering the drying cylinder 1 through the gap and contacting the fiberglass, ensuring the quality of the fiberglass.

[0047] Embodiment 3

[0048] On the basis of Embodiment 1 and Embodiment 2, there is also a pressure relief mechanism 10. The pressure relief mechanism 10 includes a pressure relief pipe 101, a pressure relief valve rod 102 and a return spring 103. Please refer to Figure 11 and Figure 12As shown, a pressure relief pipe 101 is connected to the top of the drying drum 1, and pressure relief valve rods 102 are slidably connected to the front and rear sides of the pressure relief pipe 101. The pressure relief valve rod 102 can control the air pressure, and the lower parts of the front and rear pressure relief valve rods 102 are connected to the inner side of the pressure relief pipe 101 with return springs 103.

[0049] The limiting mechanism 11 includes a positioning base frame 111, a crossbar 112 and a torsion spring 113. Figure 11 and Figure 13 As shown, a cross bar 112 is fixedly connected to the lower part of the outer right side of the drying cylinder 1, and a positioning base frame 111 is rotatably mounted on the cross bar 112. The positioning base frame 111 is in contact with the sealing cover 3. The positioning base frame 111 can limit the sealing cover 3. Torsion springs 113 are connected between the lower parts of the front and rear sides of the positioning base frame 111 and the cross bar 112.

[0050] When the glass fiber is being dried continuously, the air pressure in the drying cylinder 1 will continue to rise. When the air pressure reaches a dangerous value, the air pressure drives the pressure relief valve rods 102 on both sides to move upward, the reset spring 103 is compressed, and the pressure relief valve rods 102 on both sides move upward without sealing the drying cylinder 1. The air in the drying cylinder 1 is discharged through the pressure relief pipe 101 to complete the pressure relief. When the air pressure in the drying cylinder 1 reaches a safe value, the pressure relief valve rods 102 on both sides move downward and reset due to the action of the reset spring 103. In this way, the air pressure in the drying cylinder 1 is prevented from being too high and causing an explosion, thereby ensuring the safety of the device.

[0051] When it is necessary to pull the sealing cover 3 to swing upward to open, first pull the positioning base frame 111 to swing downward to disengage the sealing cover 3, the torsion spring 113 is compressed, and the sealing cover 3 can be opened. When the sealing cover 3 is closed, release the positioning base frame 111. Due to the action of the torsion spring 113, the positioning base frame 111 swings upward to reset and contact the sealing cover 3. The positioning base frame 111 limits the sealing cover 3. In this way, the sealing plate 96 is prevented from being poorly sealed due to unexpected factors, ensuring that the glass fiber can be dried normally.

[0052] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
