Description

Technical Field

[0001] This utility model belongs to the field of glass fiber processing technology, and in particular relates to an automatic control device for glass fiber impregnating agent level. Background Technology

[0002] Glass fiber sizing agent is an important chemical substance derived from the physical concept of "wetting". It plays a crucial role in the production and application of glass fiber. A sizing agent is a multi-component aqueous solution or water emulsion composed of water or organic solvent as medium and binders, coupling agents, surfactants, antistatic agents and other solutes. In glass fiber processing, the glass needs to be completely immersed in the glass fiber sizing agent.

[0003] In the prior art, automatic control devices for glass fiber impregnating agent levels can generally only replenish the impregnating agent when the level is insufficient. When the level is too high after the glass fiber has been added, it is not convenient to lower the level. Directly discharging the impregnating agent can easily lead to waste and is inconvenient for the next addition. Therefore, an automatic control device for glass fiber impregnating agent levels is proposed to solve the above problems. Utility Model Content

The two ends of the connecting pipe 2 are respectively connected to the interior of the impregnation tank 1 and the storage tank 3. The controller 4 is installed on one surface of the storage tank 3 by bolts. A liquid level sensor 101 is fixedly installed on the inner wall of the impregnation tank 1, and the liquid level sensor 101 is electrically connected to the controller 4. A through hole 301 is passed through the upper surface of the storage tank 3, and a piston rod 302 is slidably installed inside the through hole 301. The lower end of piston rod 302 extends into the storage tank 3. A piston plate 303 is welded to the lower end of piston rod 302. The piston plate 303 is slidably connected to the inner wall of storage tank 3, which facilitates the transmission of a signal to controller 4 when liquid level sensor 101 detects insufficient liquid level. This starts drive motor 308 to move piston plate 303 downward, pushing the wetting agent inside storage tank 3 into wetting tank 1. At the same time, when the liquid level is too high, controller 4 automatically controls piston plate 303 to rise, recovering the wetting agent inside wetting tank 1 into storage tank 3 for the next use, thus improving the convenience of using the device.

[0028] A mounting block 304 is welded to the upper surface of the storage box 3. The mounting block 304 is located on one side of the through hole 301. A mounting groove 305 is opened on one surface of the mounting block 304. A ball screw 306 is rotatably installed inside the mounting groove 305. A drive motor 308 is fixedly installed on the upper surface of the mounting block 304.

[0029] One end of the ball screw 306 extends to the outside of the mounting block 304, and the output end of the drive motor 308 is connected to the keyway of one end of the ball screw 306. The drive motor 308 is electrically connected to the controller 4.

[0030] The ball screw 306 has a threaded drive on its circumferential side with a screw nut 307. The screw nut 307 is slidably connected to the mounting groove 305. A connecting plate 309 is welded to one surface of the screw nut 307. The lower surface of the connecting plate 309 is fixedly connected to the upper surface of the piston rod 302.

[0031] A guide hole 310 is passed through one end of the upper surface of the connecting plate 309. A guide rod 311 is slidably installed inside the guide hole 310. The lower surface of the guide rod 311 is welded to the upper surface of the storage box 3. The guide rod 311 is located on the other side of the through hole 301.

[0032] A liquid replenishment pipe 312 is welded to the bottom of one surface of the storage box 3. One end of the liquid replenishment pipe 312 is connected to the inside of the storage box 3, and a second control valve 313 is installed on the circumferential side of the other end of the liquid replenishment pipe 312. The second control valve 313 is electrically connected to the controller 4.

[0033] The upper surface of the immersion tank 1 is open. Inside the immersion tank 1, a placement frame 102 is slidably installed. Two hanging plates 103 are welded to the upper surface of the placement frame 102. The two hanging plates 103 are concave plate structures and are snapped together with the upper surface of the immersion tank 1. This facilitates the concentrated placement of glass fiber into the immersion tank 1 for immersion and also makes it easy to remove the glass fiber along with the placement frame 102 after immersion. This facilitates the material handling of the device and improves its practicality. A drain pipe 104 is welded to the bottom of one surface of the immersion tank 1. One end of the drain pipe 104 is connected to the inside of the immersion tank 1, and a first control valve 105 is installed on the circumferential side of the other end of the drain pipe 104. The first control valve 105 is electrically connected to the controller 4.

[0034] Please see Figures 1-4 As shown, this utility model is an automatic control device for the liquid level of glass fiber impregnating agent. Its usage method is as follows: First, an appropriate amount of glass fiber is placed inside the placement frame 102, and then the placement frame 102 is placed inside the impregnation tank 1. The hanging plate 103 is then engaged with the impregnation tank 1 to fix the position of the placement frame 102. At this time, the liquid level sensor 101 senses the change in liquid level inside the impregnation tank 1. When it senses that the impregnating agent has not reached the standard liquid level, it will completely immerse the glass fiber at the standard liquid level. The liquid level sensor 101 transmits a signal to the controller 4, at which point the controller 4 starts the drive motor 308. The drive motor 308 drives the ball screw 306 to rotate at a constant speed. When the ball screw 306 rotates... The lead screw nut 307 moves, thereby driving the piston rod 302 to move downward. At this time, the piston plate 303 moves downward, pushing the impregnating agent inside the storage tank 3 into the impregnation tank 1 through the connecting pipe 2. When the liquid level reaches the standard liquid level, the liquid level sensor 101 transmits a signal to the controller 4 again, controlling the drive motor 308 to stop. When the liquid level is higher than the standard liquid level after the glass fiber is put in, in order to avoid unnecessary waste, the liquid level sensor 101 transmits a signal to the controller 4. The controller 4 controls the drive motor 308 to reverse, driving the piston plate 303 to rise, so that the impregnating agent inside the impregnation tank 1 enters the storage tank 3 through the connecting pipe 2.
