Description

Technical Field

[0001] The present invention relates to the technical field of static eliminators, in particular to a static eliminator for a glass fiber pulping machine. Background Art

[0002] As electronic products become lighter, thinner, and smaller, the copper-clad laminates they use as their foundation are required to be higher-density, thinner, and more multi-layered. This significantly increases the appearance and performance requirements of electronic-grade fiberglass cloth. During the operation of fiberglass sizing machines, friction between the sizing yarn and the weaving tools, as well as compression by the rollers, generates static electricity. This static electricity causes the sizing yarns to adhere to each other, leading to warp yarn breakage and poor beam winding, seriously affecting beam quality and reducing the quality and competitiveness of fiberglass cloth. This static electricity issue has become a key challenge in fiberglass cloth manufacturing.

[0003] Some current solutions use static eliminators to address static issues in sizing machines, but these solutions present significant drawbacks. To ensure effective static elimination, the eliminators are often placed too close to the yarn. While this improves elimination efficiency to a certain extent, it also presents numerous problems: They easily come into contact with the yarn, causing friction and wear on the yarn surface, impacting yarn quality and strength. Yarn impurities can easily adhere to the eliminator, causing electrode short circuits and abnormal discharges, shortening equipment life, and increasing maintenance costs and downtime. Summary of the Invention

[0004] In order to solve the above technical problems, a static elimination device for a glass fiber pulping machine is provided, which solves the problems existing in the background technology in the prior art.

[0006] The said synergistic mechanism mainly consists of a stabilizing component for stabilizing the yarn and an omnidirectional adsorption component for preventing impurities from adhering to the said static elimination rod;

[0007] Among them, the stabilizing component includes a protective frame located outside the static elimination rod, a wire pressing assembly arranged on both sides of the inside of the protective frame, and an inhibitor supply assembly arranged outside the protective frame. Corresponding wire threading grooves are opened on both sides of the protective frame. The wire threading grooves are used for threading and shrinking yarns.

[0008] Preferably, the wire pressing assembly includes two movable rotating rods symmetrically distributed up and down and a movable shaft roller tightly sleeved on the rod body of the movable rotating rod, and the movable rotating rod rotates laterally between the front and rear inner walls of the protective frame.

[0009] Preferably, the inhibitor supply assembly includes a liquid box fixed on the outer wall of the protective frame, a liquid supply cavity arranged on one side of the inner wall of the liquid box, and a liquid pressure component arranged in the liquid supply cavity. A short liquid spray tube connected to the liquid supply cavity is fixed on the bottom surface of the liquid box, and a one-way valve is built into the liquid spray short tube.

[0010] Preferably, the liquid-pressing component includes a liquid-pressing plate sliding in the liquid supply chamber and a lifting frame arranged in an inverted U-shape on a side plate of the protective frame, one end of the lifting frame penetrates into the liquid supply chamber and is fixedly connected to the liquid-pressing plate, and the other end of the lifting frame is fixed with a pressure plate, and the rod body of the movable rotating rod above is tightly sleeved with an extrusion wheel that is against the bottom surface of the pressure plate.

[0011] Preferably, a liquid storage cavity is provided on the other side of the inner wall of the liquid box, a short liquid injection tube connected to the liquid storage cavity is fixed on the top of the liquid box, a flow groove connected to the liquid supply cavity is opened at the bottom of the inner wall of one side of the liquid storage cavity, and a one-way valve 2 is provided in the flow groove.

[0012] Preferably, the omnidirectional adsorption component includes an annular vent seat which is sleeved outside the static elimination rod and rotatably connected to the pulping machine head. The outer periphery of the annular vent seat is provided with an annular notch, and a sealing ring plate fixedly connected to the pulping machine head is attached to the annular notch. The top of the annular vent seat is fixedly connected to an air suction pipe, and a number of adsorption ports corresponding to the static elimination rod are equidistantly provided on the air suction pipe. A vacuum cleaner is installed on one side wall of the protective frame, and the absorption pipe of the vacuum cleaner penetrates into the protective frame and passes through the sealing ring plate.

[0013] Preferably, a transmission rotating rod 2 is rotatably connected between the inner walls on the front and rear sides of the protective frame, and the transmission rotating rod 2 is connected to one of the movable rotating rods through a belt transmission. A supply rotation seat is also fixed on the head of the pulping machine, and a transmission rotating rod 1 is rotatably provided in the inner wall of the supply rotation seat.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) Through the setting of the protective frame, when the yarn after sizing and drying is wound inside the sizing machine head, the protective frame in the stabilization component can effectively form an anti-interference barrier outside the static elimination rod, so that the yarn will not be affected by external airflow when passing through the static elimination rod inside the protective frame, and will not shake significantly, thereby achieving stable and efficient static elimination, and effectively preventing friction contact between the yarn and the static elimination rod to a certain extent.

[0016] (2) Through the setting of the wire pressing assembly, when the yarn is passing through the inner side of the protective frame, the yarn can be synchronously passed through and retracted between the two movable shaft rollers, and then the wire pressing assemblies on both sides of the static elimination rod cooperate with each other to implement stable pressure on the yarn, reduce the shaking of the yarn when passing through the static elimination rod, and avoid the yarn from contacting and rubbing with the static elimination rod due to unstable operation.

[0017] (3) By setting up the stabilizing components, when the yarn passes through and shrinks between the two movable shaft rollers, the pressure plate and the lifting frame move back and forth as a whole, causing the antistatic agent to be output from the short spray tube and drip onto the yarn, thereby reducing the resistance of the surface of the object and making it have a certain conductivity, so that the static electricity generated by the friction of the yarn is quickly conducted, avoiding the accumulation of static electricity, and thus reducing the amount of static electricity charge on the yarn surface.

[0018] (4) Through the setting of the all-round adsorption components, when the movable shaft roller is driven by friction to rotate the movable rotating rod, the movable rotating rod can be driven by the belt to drive the transmission rotating rod 2. During the synchronization process, the transmission rotating rod 2 is driven by the driven bevel gear and the bevel gear 1 to drive the transmission rotating rod 1, causing the bevel gear 2 to engage the bevel gear disk, and then drive the annular ventilation seat, so that the annular ventilation seat carries the suction pipe to rotate around the static elimination rod, thereby comprehensively processing the impurities adhered to different parts of the static elimination rod.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] Reference Figure 1-4 As shown, a static elimination device for a glass fiber slurry machine includes a slurry machine head 1 and a static elimination rod 2 provided on the slurry machine head 1;

[0027] When the sizing machine head 1 is wound up using the built-in winding device of the sizing machine head 1, the static elimination rod 2 is assembled under the yarn. When the static elimination rod 2 is turned on, the static electricity on the surface of the yarn can be effectively eliminated in real time during the winding process, thereby preventing the sized yarns from adsorbing each other and sticking to each other due to excessive static electricity, resulting in poor yarn order.

[0028] In addition, after searching, it can be known that the existing patent announcement number is CN118639373A, and the name is an invention patent for an electrostatic elimination device for an electronic-grade glass fiber yarn slurry machine. It can be seen that the slurry machine head 1 is the head shell of the existing glass fiber slurry machine, which has a built-in winding disk to facilitate the arrangement of the yarn after slurrying and drying in the slurry machine. For the equipment known in the prior art, this case will not make too many introductions to its internal structure.

[0029] However, in order to ensure the static elimination effect, the existing technology often places the static elimination rod 2 too close to the yarn. Although this can improve the elimination efficiency to a certain extent, it brings many problems: it is easy to contact and rub with the yarn, abrading the surface fibers of the yarn, affecting the quality and strength of the yarn; impurities in the yarn are easily adsorbed on the static elimination rod 2, causing electrode short circuits and abnormal discharge, shortening the equipment life, and increasing maintenance costs and downtime.

[0030] For this purpose, refer to Figure 2 As shown, it is worth noting that it also includes a synergistic mechanism for improving the use effect of the static elimination rod 2;

[0031] The synergistic mechanism mainly consists of a stabilizing component for stabilizing the yarn and an omnidirectional adsorption component for preventing impurities from adhering to the static elimination rod 2;

[0032] The stabilizing component includes a protective frame 3 located outside the static elimination rod 2. Both sides of the protective frame 3 are provided with corresponding threading grooves for threading yarns.

[0033] Through the setting of the protective frame 3, when the yarn after sizing and drying is wound inside the sizing machine head 1, the protective frame 3 in the stabilization component can effectively form an anti-interference barrier outside the static elimination rod 2, so that the yarn will not be affected by external airflow when passing through the static elimination rod 2 inside the protective frame 3, and will not shake significantly, thereby achieving stable and efficient static elimination, and effectively preventing friction contact between the yarn and the static elimination rod 2 to a certain extent.

[0034] Further, refer to Figure 2 As shown, it is worth noting that the stabilization component also includes wire pressing assemblies arranged on both sides of the interior of the protective frame 3, and the static elimination rod 2 is located between the two sets of wire pressing assemblies;

[0035] The thread pressing assembly includes two movable rotating rods 4 symmetrically distributed up and down and a movable shaft roller 5 tightly sleeved on the rod body of the movable rotating rod 4. The movable rotating rod 4 rotates horizontally between the front and rear inner walls of the protective frame 3, and the yarn is passed through and retracted between the two movable shaft rollers 5.

[0036] Through the setting of the wire pressing assembly, when the yarn is passed through and shrunk inside the protective frame 3, the yarn can be passed through and shrunk between the two movable shaft rollers 5 synchronously, and then the wire pressing assemblies on both sides of the static elimination rod 2 cooperate with each other to implement stable pressurization of the yarn, reduce the jitter of the yarn when passing through the static elimination rod 2, and avoid the yarn from contacting and rubbing with the static elimination rod 2 due to unstable operation.

[0037] Although the above embodiment uses a method of applying pressure to stabilize the yarn by a wire pressing assembly to prevent the yarn from contacting and rubbing with the static eliminator 2 due to unstable operation, this device will cause excessive contact between the yarn and the movable shaft roller 5. Due to friction, the static electricity on the yarn surface increases, thereby causing the yarn to generate more static electricity, reducing the static eliminator effect of the static eliminator 2 on the yarn;

[0038] For this purpose, refer to Figure 2-3 As shown, it is worth noting that the stabilization component further includes an inhibitor supply assembly disposed outside the protective frame 3, and the inhibitor supply assembly cooperates with one set of wire pressing assemblies;

[0039] The inhibitor supply assembly includes a liquid box 6 fixed to the outer wall of the protective frame 3, a liquid supply chamber 7 provided on one side of the inner wall of the liquid box 6, and a liquid pressure member provided in the liquid supply chamber 7. A liquid spray short tube 8 connected to the liquid supply chamber 7 is fixed to the bottom surface of the liquid box 6 and has a built-in one-way valve 1.

[0040] The liquid-pressing member includes a liquid-pressing plate 9 that slides in the liquid-supply chamber 7 and a lifting frame 10 that is arranged in an inverted U-shape on a side plate of the protective frame 3. One end of the lifting frame 10 penetrates into the liquid-supply chamber 7 and is fixedly connected to the liquid-pressing plate 9. The other end of the lifting frame 10 is fixed with a pressure plate 11. The upper movable rotating rod 4 is tightly sleeved with an extrusion wheel 12 that abuts against the bottom surface of the pressure plate 11.

[0041] A liquid storage chamber 15 is provided on the other side of the inner wall of the liquid box 6. A liquid injection short tube 16 connected to the liquid storage chamber 15 is fixed to the top of the liquid box 6. A flow groove connected to the liquid supply chamber 7 is opened at the bottom of the inner wall of one side of the liquid storage chamber 15. A one-way valve 2 is provided in the flow groove;

[0042] By setting up the stabilizing component, when the yarn passes through and shrinks between the two movable shaft rollers 5, the movable shaft rollers 5 are driven by friction to rotate the movable rotating rod 4, and then the squeezing wheel 12 rotates synchronously and intermittently squeezes the pressure plate 11, so that the pressure plate 11 and the lifting frame 10 can move back and forth as a whole. During this process, when the lifting frame 10 is forced to rise, the lifting frame 10 can synchronously carry the pressure plate 9 to slide upward on the inside of the liquid supply chamber 7, so that the one-way valve 2 in the flow groove is opened by air pressure, so that the antistatic agent stored in the liquid storage chamber 15 is passed into the liquid supply chamber 7;

[0043] During the process of the lifting frame 10 sliding up, the stretching ring 13 synchronously stretches the stretching spring 14 of the lifting frame 10 to deform. In this way, the elastic force of the stretching spring 14 is utilized. When the pressure plate 11 is no longer squeezed by the squeezing wheel 12, the stretching ring 13 can be driven by the elastic force of the stretching spring 14 to drive the lifting frame 10 to slide down and push the pressure plate 9 downward, causing the pressure plate 9 to squeeze the antistatic agent introduced into the liquid supply chamber 7, causing the antistatic agent to be output from the liquid spray short tube 8 and drip and dye the yarn, thereby reducing the resistance of the object surface and making it have a certain conductivity, so that the static electricity generated by friction on the yarn is quickly conducted, avoiding static electricity accumulation, and thus reducing the amount of static electricity charge on the yarn surface.

[0044] In addition, refer to Figure 2-4 As shown, it is worth noting that the omnidirectional adsorption component includes an annular vent seat 17 which is sleeved outside the static elimination rod 2 and is rotatably connected to the pulping machine head 1. The outer periphery of the annular vent seat 17 is provided with an annular notch, and a sealing ring plate 18 fixedly connected to the pulping machine head 1 is fitted on the annular notch. The top of the annular vent seat 17 is fixedly connected to a suction pipe 19, and a plurality of adsorption ports corresponding to the static elimination rod 2 are equidistantly opened on the suction pipe 19. A dust collector 20 is installed on one side wall of the protective frame 3, and the absorption pipe of the dust collector 20 penetrates the protective frame 3 and passes through the sealing ring plate 18.

[0045] A second transmission rod 24 is rotatably connected between the inner walls on both sides of the front and rear sides of the protective frame 3. The second transmission rod 24 is connected to one of the movable rotation rods 4 through a belt drive. A supply rotation seat 23 is also fixed on the pulping machine head 1. A transmission rotation rod 1 21 is rotatably connected in the inner wall of the supply rotation seat 23. A bevel gear 1 is fixed to one end of the transmission rotation rod 1 21. A driven bevel gear 25 combined with the bevel gear 1 is sleeved on the rod body of the transmission rotation rod 24. A bevel gear 2 is fixed to the other end of the transmission rotation rod 1 21. A bevel gear 2 is fixed to the outer periphery of the top surface of the annular vent seat 17. A bevel gear disk 22 meshing with the bevel gear 2 is fixed;

[0046] By setting up the all-round adsorption components, when the movable shaft roller 5 is driven by friction to rotate the movable rotating rod 4, the movable rotating rod 4 can be driven by the belt to drive the transmission rotating rod 24. During the synchronization process, the transmission rotating rod 24 is driven by the driven bevel gear 25 and the bevel gear 1 to drive the transmission rotating rod 1 21, causing the bevel gear 2 to engage the bevel gear disk 22, and then drive the annular vent seat 17, so that the annular vent seat 17 carries the suction pipe 19 to rotate around the static elimination rod 2, thereby comprehensively processing the impurities adhered to different parts of the static elimination rod 2.
