Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for glass fiber cloth. Background Technology

[0002] Fiberglass cloth is a fabric woven from fiberglass. It has many excellent properties and is widely used in industrial and construction fields. In the production and processing of fiberglass cloth, drying equipment is usually used to dry the fiberglass cloth.

[0003] When using a drying device to dry sheet-like fiberglass cloth, the usual procedure is to pull out the rack inside the drying chamber, place the fiberglass cloth on the rack, and then push the rack back into the drying chamber for drying. However, since the air inlet of the drying chamber is usually located at the top, the side of the fiberglass cloth below the rack and furthest from the air inlet dries more slowly, resulting in incomplete drying and low efficiency when using the drying device to dry the fiberglass cloth. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the air inlet of the drying box is usually located at the top of the drying box, and the drying progress is slow on the side of the fiberglass cloth located below the drying rack and away from the air inlet, resulting in incomplete drying effect and low efficiency when using a drying device to dry fiberglass cloth. Therefore, a fiberglass cloth drying device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for fiberglass cloth, comprising a box, a blowing assembly, a placement rack, and several electric heating rods. The blowing assembly is located at the top of the inner wall of the box and consists of a drive motor and several fan blades, with the fan blades fixed to the output end of the drive motor. The electric heating rods are located below the blowing assembly at the top of the inner wall of the box. An air inlet slot is provided at the top of the box, and an air outlet is provided on one side of the inner wall of the box. Two door panels are hinged to one side of the box. The placement rack has casters at its bottom for easy movement, and a flipping device is provided on the outer surface of the placement rack to flip the fiberglass cloth placed on the rack for easy drying.

[0006] Preferably, the flipping device includes a first grooved wheel and a second grooved wheel, which rotate on one side of the inner wall of the housing. The first and second grooved wheels have different diameters. A transmission belt is fitted onto the outer surface of the first and second grooved wheels. A servo motor is installed on one side of the outer surface of the housing, and the output end of the servo motor is fixedly connected to one side of the first grooved wheel. A slot is provided on one side of both the first and second grooved wheels. The flipping device also includes two first mesh plates, one end of which is fixedly connected to a shaft. The shaft rotates on the inner wall of the placement rack to connect the first mesh plate and the placement rack. Two first mesh plates are located near the top and bottom of the placement rack surface, respectively. A sliding rod is slidably connected to the inner wall of the shaft. A first spring is provided at one end of the sliding rod, which is located inside the shaft to limit the position of the sliding rod within the shaft. A rectangular rod is fixedly connected to one side of the sliding rod. Pulling the rectangular rod can control the movement of the sliding rod. A rotating wheel is rotatably connected to the end of the first mesh plate away from the shaft. Two grooved rods are fixedly connected to one side of the inner wall of the box. A positioning device is provided on the outer surface of the first mesh plate to limit the position of the glass fiber cloth on the first mesh plate.

[0007] The effect achieved by the above components is as follows: When using the drying device, first place the fiberglass cloth on the surface of the two first mesh plates on the placement rack, fix the position of the fiberglass cloth by the positioning device, then push the placement rack into the interior of the box, so that the rotating wheels at one end of the two first mesh plates enter the two grooves on one side of the inner wall of the box. Push the placement rack to continue moving so that the shafts at one end of the two first mesh plates approach the first groove wheel and the second groove wheel respectively. Pull the rectangular rods on one side of the two shafts to control the sliding rod to slide inward on the inner wall of the groove and compress the first spring. Continue to push the placement rack so that the two shafts are aligned with the positions of the first groove wheel and the second groove wheel respectively. Release the two rectangular rods and push the sliding rod outward by the first spring compressed inside the shaft, so that one end of the sliding rod is inserted into the slots of the first groove wheel and the second groove wheel respectively. Then close the door panel on one side of the box and turn on the electric heating. The heating rod is powered on to raise the temperature. The drive motor of the blower assembly drives the fan blades to rotate, generating airflow that blows hot air into the chamber. Moisture can be discharged through the air outlet on one side of the chamber. Then, the servo motor on the outside of the chamber is activated, which drives the first grooved wheel to rotate, causing the first mesh plate located near the top of the placement rack to rotate. At the same time, the transmission belt moves on the surfaces of the first and second grooved wheels, driving the second grooved wheel to rotate. Because the diameters of the first and second grooved wheels are different, the rotation speeds of the two first mesh plates driven by the first and second grooved wheels are different, preventing the two first mesh plates from colliding when rotating. After drying is completed, the power to the chamber is turned off, the chamber door is opened, and the two rectangular rods are pulled to move the sliding rod so that the sliding rod disengages from the slot. Then, the placement rack is pulled out of the chamber, and the fiberglass cloth on the first mesh plate is removed.

[0008] Preferably, two positioning rods are fixedly connected to one side of the placement rack, and the ends of the two rectangular rods away from the inner wall of the sliding rod slide on the outer surface of the positioning rod.

[0009] The effect achieved by the above components is that when the rectangular rod is pulled to control the movement of the sliding rod, the end of the rectangular rod away from the sliding rod will slide on the outer surface of the positioning rod. The positioning rod can further limit the angle between the rectangular rod and the placement frame and the shaft, and avoid the angle of the end of the rectangular rod away from the sliding rod from deflecting as much as possible.

[0010] Preferably, one end of the rectangular rod is provided with an auxiliary component that can temporarily fix the position of the rectangular rod and the sliding rod. The auxiliary component includes a groove block, and one side of the groove block is rotatably connected to a rotating rod via a rotating shaft.

[0011] The effect achieved by the above components is as follows: when the placement rack is moved into the box, pulling the rectangular rod controls the sliding rod to retract into the shaft and compress the first spring, which can push the rotating rod on one side of the slot block to rotate. One end of the rotating rod is pressed against the outer surface of the placement rack to temporarily fix the position of the rectangular rod and the sliding rod. After the shaft is moved to the side of the first groove wheel, rotating the rotating rod to make it parallel with the rectangular rod can release the fixation, thus improving the convenience of connecting the shaft to the first groove wheel or the second groove wheel.

[0012] Preferably, one end of the rotating rod is fixedly connected to an anti-slip block, which is made of high-temperature resistant rubber.

[0013] The effect achieved by the above components is that when the end of the rotating rod equipped with the rubber anti-slip block is pressed against the outer surface of the placement frame, the rotating rod is less likely to slide on its own, and the position of the rectangular rod is more stably fixed.

[0014] Preferably, the positioning device includes several round rods and a ring, as well as a second mesh plate.

[0015] Round rods: Several round rods are fixedly connected to the top four corners of the first mesh plate to support the ring and the second mesh plate;

[0016] Ring: The ring is fixed at the four corners of the second mesh plate and slides on the outer surface of the rod to control the movement of the second mesh plate;

[0017] A second spring is provided on the outer surface of the round rod. The second spring is located below the ring and is used to limit the position of the ring on the outside of the round rod.

[0018] The effect achieved by the above components is as follows: when placing the fiberglass cloth, pulling the second mesh plate controls the rings at the four corners of the second mesh plate to slide upward on the outer surface of the round rod and compress the second spring. Then, the fiberglass cloth is placed on the surface of the first mesh plate. The second mesh plate is released, and the rings are pushed downward on the outer surface of the round rod by the second spring to press the second mesh plate onto the surface of the fiberglass cloth, thus fixing the position of the fiberglass cloth on the first mesh plate and avoiding wrinkles on the surface of the fiberglass cloth during the drying process as much as possible.

[0019] Preferably, an auxiliary rod is fixedly connected to one side of the top of the second mesh plate.

[0020] The effect achieved by the above components is that holding the outer surface of the auxiliary rod makes it easier to pull the second mesh plate to move its position on the outer surface of the round rod via the ring.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a flipping device, the glass fiber cloth is placed on the surfaces of two first mesh plates located on the placement rack. The two first mesh plates are rotated inside the box by operating a servo motor, so that the hot air blown by the electric heating rod by the blowing assembly can be blown more comprehensively onto the surface of the glass fiber cloth, thereby improving the efficiency and drying effect of drying the glass fiber cloth.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Example 1, as Figures 1-2 As shown, a fiberglass cloth drying device includes a housing 1, a blowing assembly 5, a placement rack 7, and several electric heating rods 6. The blowing assembly 5 is located at the top of the inner wall of the housing 1 and consists of a drive motor and several fan blades. The fan blades are fixed to the output end of the drive motor. The electric heating rods 6 are located below the blowing assembly 5 at the top of the inner wall of the housing 1. An air inlet slot 4 is provided at the top of the housing 1, and an air outlet 8 is provided on one side of the inner wall of the housing 1. Two door panels are hinged to one side of the housing 1. The bottom of the placement rack 7 is provided with casters for easy movement, and the outer surface of the placement rack 7 is provided with a flipping device 2 that can flip the fiberglass cloth placed on the placement rack 7 for easy drying.

[0035] Reference Figures 1-6As shown, this embodiment discloses a flipping device 2 including a first grooved wheel 22 and a second grooved wheel 23. The first grooved wheel 22 and the second grooved wheel 23 rotate on one side of the inner wall of the housing 1, respectively. The diameters of the first grooved wheel 22 and the second grooved wheel 23 are different. A transmission belt 24 is sleeved on the outer surface of the first grooved wheel 22 and the second grooved wheel 23. A servo motor 21 is provided on one side of the outer surface of the housing 1. The output end of the servo motor 21 is fixedly connected to one side of the first grooved wheel 22. A slot 25 is provided on one side of both the first grooved wheel 22 and the second grooved wheel 23. The flipping device 2 also includes two first mesh plates 26. One end of the first mesh plate 26 is fixedly connected to a shaft 29. The shaft 29 rotates on the inner wall of the placement frame 7 to connect the first mesh plate 26 and the placement frame 7. Plates 26 are located near the top and bottom of the surface of the rack 7, respectively. A sliding rod 210 is slidably connected to the inner wall of the shaft 29. A first spring 211 is provided at one end of the sliding rod 210. The first spring 211 is located inside the shaft 29 and is used to limit the position of the sliding rod 210 within the shaft 29. A rectangular rod 212 is fixedly connected to one side of the sliding rod 210. Pulling the rectangular rod 212 can control the movement of the sliding rod 210. A rotating wheel 27 is rotatably connected to the end of the first mesh plate 26 away from the shaft 29. Two grooved rods 28 are fixedly connected to one side of the inner wall of the box 1. A positioning device 3 is provided on the outer surface of the first mesh plate 26 to limit the position of the glass fiber cloth on the first mesh plate 26. When using the drying device, the glass fiber cloth is first placed on the drying rack 26. The two first mesh plates 26, placed on the placement rack 7, are positioned by the positioning device 3. The placement rack 7 is then pushed into the housing 1, causing the rollers 27 at one end of each of the two first mesh plates 26 to enter the two grooved rods 28 on one side of the inner wall of the housing 1. The placement rack 7 is then pushed further, causing the shafts 29 at one end of each of the two first mesh plates 26 to approach the first grooved wheel 22 and the second grooved wheel 23 respectively. The rectangular rods 212 on one side of the two shafts 29 are pulled, controlling the sliding rods 210 to slide inwards along the inner wall of the grooved rods 28 and compress the first spring 211. The placement rack 7 is then pushed further, aligning the two shafts 29 with the positions of the first grooved wheel 22 and the second grooved wheel 23 respectively. The two rectangular rods 212 are then released, allowing the shafts 29 to pass through... The compressed first spring 211 pushes the sliding rod 210 outward, inserting one end of the sliding rod 210 into the slots 25 of the first grooved wheel 22 and the second grooved wheel 23 respectively. Then, the door panel on one side of the box 1 is closed, and the electric heating rod 6 is energized to heat up. The drive motor of the blower assembly 5 drives the fan blades to rotate, generating wind to blow hot air into the box 1. Moisture can be discharged through the air outlet 8 on one side of the box 1. Then, the servo motor 21 on the outside of the box 1 is operated, which drives the first grooved wheel 22 to rotate, causing the first mesh plate 26 located near the top of the placement rack 7 to rotate. At the same time, the transmission belt 24 moves on the surface of the first grooved wheel 22 and the second grooved wheel 23, driving the second grooved wheel 23 to rotate.Because the diameters of the first grooved wheel 22 and the second grooved wheel 23 are different, the rotation speeds of the two first mesh plates 26 driven by the first grooved wheel 22 and the second grooved wheel 23 are different, preventing the two first mesh plates 26 from colliding during rotation. After drying, the power to the chamber 1 is turned off, the chamber door is opened, and the two rectangular rods 212 are pulled to control the sliding rod 210 to move so that the sliding rod 210 disengages from the slot 25. Then, the placement rack 7 is pulled out of the chamber 1, and the fiberglass cloth on the first mesh plate 26 is removed. By setting the flipping device 2, the fiberglass cloth is placed on the surface of the two first mesh plates 26 on the placement rack 7. The servo motor 21 drives the two first mesh plates 26 to rotate inside the chamber 1, allowing the hot air blown by the heating rod 6 from the blowing assembly 5 to be more comprehensively blown onto the surface of the fiberglass cloth, improving the efficiency and drying effect of the fiberglass cloth.

[0036] Reference Figures 2-6 As shown, this embodiment discloses that two positioning rods 213 are fixedly connected to one side of the placement rack 7. The ends of the two rectangular rods 212 away from the inner wall of the sliding rod 210 slide on the outer surface of the positioning rods 213. When the rectangular rods 212 are pulled to control the sliding rod 210 to move, the ends of the rectangular rods 212 away from the sliding rod 210 will slide on the outer surface of the positioning rods 213. The positioning rods 213 can further limit the angle between the rectangular rods 212 and the placement rack 7 and the shaft 29, so as to avoid the angle of the ends of the rectangular rods 212 away from the sliding rod 210 from deflecting as much as possible.

[0037] Reference Figures 5-6 As shown, this embodiment discloses an auxiliary component 214 at one end of the rectangular rod 212, which can temporarily fix the position of the rectangular rod 212 and the sliding rod 210. The auxiliary component 214 includes a groove block 2141. One side of the groove block 2141 is rotatably connected to a rotating rod 2142 via a rotating shaft. When the placement rack 7 is moved into the box 1, pulling the rectangular rod 212 controls the sliding rod 210 to retract into the shaft 29 and compress the first spring 211, which can push the rotating rod 2142 on one side of the groove block 2141 to rotate, so that one end of the rotating rod 2142 abuts against the outer surface of the placement rack 7, thereby fixing the rectangular rod. The positions of 212 and sliding rod 210 are temporarily fixed. After the shaft 29 is moved to one side of the first grooved wheel 22, the fixed position can be released by rotating the rotating rod 2142 parallel to the rectangular rod 212. This improves the convenience of connecting the shaft 29 to the first grooved wheel 22 or the second grooved wheel 23. One end of the rotating rod 2142 is fixedly connected to an anti-slip block 2143. The anti-slip block 2143 is made of high-temperature resistant rubber. When the end of the rotating rod 2142 with the rubber anti-slip block 2143 is pressed against the outer surface of the placement frame 7, the rotating rod 2142 is less likely to slide on its own, making the position of the rectangular rod 212 more stable.

[0038] Reference Figure 1 ,Figure 6 and Figure 7 As shown, this embodiment discloses a positioning device 3 comprising a plurality of round rods 31, a ring 32, and a second mesh plate 34. The round rods 31 are respectively fixedly connected to the four corners of the top of the first mesh plate 26 to support the ring 32 and the second mesh plate 34. The ring 32 is fixed at the four corners of the second mesh plate 34 and slides on the outer surface of the round rods 31 to control the movement of the second mesh plate 34. A second spring 33 is provided on the outer surface of the round rods 31, located below the ring 32 to restrict the position of the ring 32 outside the round rods 31. When placing the fiberglass cloth, pull the second mesh plate 34 to control the rings 32 at the four corners of the second mesh plate 34 to slide upward on the outer surface of the round rod 31 and compress the second spring 33. Then place the fiberglass cloth on the surface of the first mesh plate 26, release the second mesh plate 34, and push the rings 32 downward on the outer surface of the round rod 31 through the second spring 33 to press the second mesh plate 34 onto the surface of the fiberglass cloth, fix the position of the fiberglass cloth on the first mesh plate 26, and avoid wrinkles on the surface of the fiberglass cloth as much as possible during the drying process.

[0039] Reference Figure 6 and Figure 7 As shown in the figure, this embodiment discloses that an auxiliary rod 35 is fixedly connected to one side of the top of the second mesh plate 34. Holding the outer surface of the auxiliary rod 35 makes it easier to pull the second mesh plate 34 to move its position on the outer surface of the round rod 31 via the ring 32.

[0040] Working principle: When using the drying device, pulling the second mesh plate 34 controls the rings 32 at the four corners of the second mesh plate 34 to slide upward on the outer surface of the round rod 31 and compress the second spring 33. Then, the fiberglass cloth is placed on the surface of the first mesh plate 26. The second mesh plate 34 is released, and the second spring 33 pushes the rings 32 downward on the outer surface of the round rod 31, pressing the second mesh plate 34 onto the surface of the fiberglass cloth and fixing the position of the fiberglass cloth on the first mesh plate 26. Then, the placement rack 7 is pushed into the interior of the box 1, so that the rotating wheels 27 at one end of the two first mesh plates 26 respectively enter the two grooves 2 on one side of the inner wall of the box 1. Inside 8, the placement frame 7 is pushed to continue moving, causing the shafts 29 at one end of the two first mesh plates 26 to approach the first grooved wheel 22 and the second grooved wheel 23 respectively. The rectangular rods 212 on one side of the two shafts 29 are pulled to control the sliding rods 210 to slide inward on the inner wall of the groove rod 28 and compress the first spring 211. The placement frame 7 is pushed to align the two shafts 29 with the positions of the first grooved wheel 22 and the second grooved wheel 23 respectively. The two rectangular rods 212 are released, and the first spring 211 compressed inside the shafts 29 pushes the sliding rods 210 to move outward, inserting one end of the sliding rods 210 into the slots 2 of the first grooved wheel 22 and the second grooved wheel 23 respectively. 5. Inside, the door panel on one side of the cabinet 1 is then closed, and the electric heating rod 6 is powered on to heat up. The drive motor of the blower assembly 5 drives the fan blades to rotate, generating wind to blow hot air into the cabinet 1. Moisture can be discharged through the air outlet 8 on one side of the cabinet 1. Then, the servo motor 21 on the outside of the cabinet 1 is operated, which drives the first grooved wheel 22 to rotate, causing the first mesh plate 26 located near the top of the placement rack 7 to rotate. At the same time, the transmission belt 24 moves on the surface of the first grooved wheel 22 and the second grooved wheel 23, driving the second grooved wheel 23 to rotate. Due to the rotation of the first grooved wheel 22 and the second grooved wheel 23... The diameters of the two mesh plates 26 are different, and the rotation speeds of the two mesh plates 26 driven by the first grooved wheel 22 and the second grooved wheel 23 are different, so that the two mesh plates 26 will not collide when rotating. During the drying process, the pressure of the second mesh plate 34 can minimize the wrinkles on the surface of the fiberglass cloth during the drying process. After drying, turn off the power of the chamber 1, open the chamber door, pull the two rectangular rods 212 to control the sliding rod 210 to move so that the sliding rod 210 is disengaged from the slot 25, then pull the placement rack 7 out of the chamber 1, push the second mesh plate 34 upward, and remove the fiberglass cloth located on the first mesh plate 26.
