DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 4As shown, a feeding device proposed by the utility model includes a bottom plate 1, an air suction component, a transmission roller 6, a driving component, a roller shaft 14 and a tensioning adjustment mechanism. The bottom plate 1 is connected to the mounting plate 2, and the mounting plate 2 is connected to the air collecting hood 3 with an opening facing upward, and a porous plate 4 is arranged at the opening of the air collecting hood 3. The input end of the air suction component is connected to the inside of the air collecting hood 3, and the output end of the fan 5 is connected to the outside. The air suction component includes a fan 5, and an exhaust pipe is arranged at the input end of the fan 5. The other end of the exhaust pipe is inserted into the air collecting hood 3 and connected to the inside of the air collecting hood 3. An exhaust pipe is arranged at the output end of the fan 5, and the other end of the exhaust pipe extends to the side of the mounting plate 2 away from the conveyor belt 7. Two transmission rollers 6 are both rotatably connected to the mounting plate 2 and are respectively located on both sides of the air collecting hood 3. The transmission rollers 6 on both sides are connected by a conveyor belt 7 for transmission. The conveyor belt 7 is a porous conveyor belt, and the lower surface of the upper horizontal end of the conveyor belt 7 slides along the upper surface of the porous plate 4. The driving assembly includes a motor 8, which is arranged on the mounting plate 2. The output end of the motor 8 is connected to the end of one of the transmission rollers 6. The driving assembly drives the transmission roller 6 to rotate to drive the conveyor belt 7 to operate. The roller shaft 14 is connected to the mounting plate 2 and is rotatably connected to the unwinding roll. The tensioning adjustment mechanism is connected to the mounting plate 2, and the tensioning adjustment mechanism includes a guide roller B10 and a guide roller C12. A chute 201 is arranged on the mounting plate 2 near the feed end of the conveyor belt 7. Two guide rollers B10 are respectively located on both sides of the chute 201 and are rotatably connected to the mounting plate 2. A slider 11 is arranged in the chute 201 and is slidably connected to the inner wall thereof. The guide roller C12 is rotatably connected to the slider 11. A resistance adjustment assembly 13 for adjusting the sliding resistance of the slider 11 in the chute 201 is arranged on the mounting plate 2. The resistance adjustment assembly 13 includes a slide rod 131, a hollow tube 132, a limit ring 133 and a spring 134. The slide bar 131 is located in the slide groove 201 and connected to its inner wall. The slide bar 131 passes through the slider 11 in the vertical direction and is slidably connected to it. The hollow tube 132 is inserted into the slide groove 201 downward along the top of the mounting plate 2, and the hollow tube 132 is spirally connected to the mounting plate 2. The top of the slide bar 131 is inserted into the hollow tube 132 and is slidably connected to its inner wall. The limit ring 133 is connected to the hollow tube 132 and slides with the slide bar 131. The spring 134 is sleeved on the outside of the slide bar 131. The two ends of the spring 134 are respectively abutted against the limit ring 133 and the side of the slider 11 that are close to each other. The tension adjustment mechanism adjusts the tension of the glass fiber cloth pulled from the unwinding roll to the conveyor belt 7 through the adaptive lifting of the guide roller C12 in the working state. The guide roller A9 is rotatably set on the mounting plate 2 between the feed end of the conveyor belt 7 and the guide roller B10 on the side close to the feed end of the conveyor belt 7. The bottom of the guide roller A9 is lower than the upper surface of the upper horizontal end of the conveyor belt 7.

[0027] In this embodiment, the glass fiber cloth unwinding roll is inserted on the roller shaft 14, and the end of the glass fiber cloth is pulled according to Figure 1As shown, the glass fiber cloth is passed around the right guide roller B10, guide roller C12, left guide roller B10 and guide roller A9 in sequence, and then the glass fiber cloth is pulled to its front end and attached to the upper surface of the upper horizontal end of the conveyor belt 7, and the glass fiber cloth is placed above the porous plate 4, and then the fan 5 is started, and the fan 5 extracts air from the air collecting hood 3. At this time, the glass fiber cloth is attached to the surface of the conveyor belt 7 under the adsorption effect, and then the motor 8 is started, and the motor 8 drives the conveyor belt 7 to operate. At this time, the glass fiber cloth is driven along with the conveyor belt 7 due to the adsorption effect, and the glass fiber cloth maintains good flatness during the conveying process. When the glass fiber cloth is suspended from conveying, the unloading roll at the feeding end will continue to operate due to inertia, which will cause the glass fiber cloth to be too loose. At this time, the slider 11 and the guide roller B12 automatically slide down and keep the glass fiber cloth flat. When the glass fiber cloth is conveyed too tight, the slider 11 and the guide roller B12 slide up due to the upward support force of the glass fiber cloth, thereby achieving the purpose of automatically adjusting the tension of the glass fiber cloth. The sliding resistance of the slider 11 can be adjusted by rotating the hollow tube 132. When the hollow tube 132 is screwed upward, the spring is relaxed and the initial sliding resistance of the slider 11 is reduced. When the hollow tube 132 is screwed downward, the spring is compressed and the initial sliding resistance of the slider 11 is increased.

[0030] In this embodiment, the overall weight of the glass fiber cloth unwinding roll is relatively large, and the support plate A151 and the support plate B156 can support the roller shaft 14 at the same time to prevent the roller shaft 14 from bending downward under the heavy pressure, and the support plate 151 and the support plate B156 are respectively adjusted by the linear module A152 and the linear module B154. This structure can be used to adjust the unwinding position of the glass fiber cloth unwinding roll, and at the same time, the glass fiber cloth unwinding roll can be clamped and limited from both sides; when the glass fiber cloth unwinding roll needs to be replaced, it is only necessary to start the hydraulic cylinder 155 to pull down the support plate B156, which is simple and convenient to operate.
