Description

Technical Field

[0001] This utility model relates to the field of fiberglass cloth processing technology, and in particular to an electronic-grade fiberglass cloth hydroentanglement splitting machine. Background Technology

[0002] Electronic-grade fiberglass cloth uses hydroentangled fiber opening technology, mainly to solve the inherent defects of traditional mechanical fiber opening processes and meet the stringent requirements of high-end electronic materials for uniformity, strength and signal integrity.

[0003] Chinese Patent No. CN218621379U discloses a hydroentangled fiber splitting device. This utility model is applicable to the splitting of glass fiber cloth. It uses a guide plate to guide the flow of the hydroentangled fibers sprayed by the water spraying mechanism, thereby slowing down the flow rate of the hydroentangled fibers and preventing them from colliding with the water in the lower water tank at high speed and generating foam. This prevents foam from affecting the quality of the product and ensures the working effect of the device.

[0004] However, the device still has shortcomings: when the device is in actual operation, the collision between water and fiberglass cloth will produce a large number of water droplets splashing everywhere, and the device lacks a structure for drying after hydroentanglement, resulting in its relatively simple function. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an electronic-grade glass fiber cloth hydroentanglement fiber opener.

[0006] The technical solution of this utility model is as follows: an electronic grade glass fiber cloth hydroentanglement opening machine, including a base, a lower header set on the base, a T-shaped groove with an upward opening on the lower header, and an inclined groove on each side of the vertical end of the T-shaped groove on the lower header.

[0007] The receiving hopper is located inside the horizontal end of the T-shaped trough, and a drain pipe is installed at the bottom of the receiving hopper, which is inserted below the liquid surface.

[0008] A fixed seat is centrally located on the inner side of the vertical end of the T-shaped groove. A guide roller A is installed on the fixed seat. Two arc-shaped plates with similar convex surfaces are symmetrically arranged at the bottom of the fixed seat and are rotatably connected to it.

[0009] Drive component A is installed on the lower header. When in operation, drive component A drives the two curved plates on both sides to flip in opposite directions.

[0010] The bracket is set on the lower header, and a movable plate is movably installed on the bracket. Two sets of pressure rollers are symmetrically arranged at the bottom of the movable plate, and two sets of water jet nozzles are arranged between the two pressure rollers at the bottom of the movable plate.

[0011] Drive component B is mounted on the bracket and drives the movable plate to rise or fall.

[0012] And an air guide shroud, which is set at the output end of the lower header. A perforated electric heating plate is installed inside the air guide shroud, and a fan is installed on the base. The input end of the fan is inserted into the horizontal end of the T-shaped groove and is located above the liquid surface. The output end of the fan is connected to the input end of the air guide shroud.

[0013] Preferably, a drain pipe is installed on the lower header, the drain pipe is inserted into the T-shaped groove and located below the liquid surface, and a flow valve is installed on the drain pipe to control its internal on / off state and flow rate.

[0014] Preferably, the bottom surface of the inclined groove is provided with a guide roller B at the same height as the guide roller A.

[0015] Preferably, the drive assembly A includes a gear, a worm gear, and a worm. An mounting shaft is provided on the arc-shaped plate. The mounting shaft is rotatably connected to the lower header and the fixed seat. There are two gears, which are coaxially connected to the mounting shafts on their respective sides and mesh with each other. The worm gear is coaxially connected to one of the mounting shafts. The worm is rotatably connected to the lower header and meshes with the worm gear. A crank A is provided at one end of the worm.

[0016] Preferably, two baffles are provided at the bottom of the movable plate, and two sets of pressure rollers are respectively rotatably arranged at the bottom of the baffles on the corresponding side, and the two sets of pressure rollers are respectively located above the guide roller B on the corresponding side.

[0017] Preferably, a drying box is provided inside the air guide shroud between its input end and the porous heating plate. The drying box is slidably connected to the air guide shroud and is filled with desiccant.

[0018] Preferably, a set of fixing frames is provided on both sides of the lower header on the base, and a guide roller C is rotatably mounted on the fixing frame. A limiting mechanism is provided on the guide roller C to prevent the fiberglass cloth from deviating.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects: By setting an inclined trough connected to the vertical end of the T-shaped channel, a guide roller B is installed on the bottom surface of the inclined trough, and a water baffle is installed on the movable plate. A pressure roller is installed at the bottom of the water baffle, which effectively prevents water from splashing everywhere when it collides with the fiberglass cloth, confining it within the lower header. By setting two sets of arc-shaped plates with adjustable angles, the water impacts the concave surface of the arc-shaped plates as it passes through the fiberglass cloth. The arc-shaped plates guide the water to both sides of the horizontal end of the T-shaped channel, preventing it from splashing upwards. This avoids the downward-flowing water colliding with the water in the lower header, thus preventing foam from being generated and dissipated. The water droplets splash onto the fiberglass cloth. By setting up a combined structure of an air guide hood and a fan, the fan draws air from below the fiberglass cloth, promoting the downward movement of water droplets and further preventing water droplet splashing. Then, the fan sends the drawn air into the air guide hood, where the desiccant and porous electric heating plate inside the air guide hood dehumidify and heat the air before blowing it onto the fiberglass cloth to dry it. At the same time, this utility model also sets up a guide roller C and a limiting mechanism composed of a ring frame, a positioning ring, a slide, and a drive component C, which can prevent the fiberglass cloth from deviating during the conveying process and ensure that the fiber opening quality of the fiberglass cloth is consistent throughout.

[0022] Example 1 like Figures 1-4As shown, this utility model proposes an electronic-grade fiberglass cloth hydroentanglement opener, comprising a base 1, a receiving hopper 4, a fixed base 6, a drive assembly A, a bracket 19, a drive assembly B, and an air guide hood 25. A lower header 2 is mounted on the base 1, and a T-shaped groove 201 with an upward-facing opening is provided on the lower header 2. An inclined groove 202 is provided on each side of the vertical end of the T-shaped groove 201 on the lower header 2. A drain pipe 3 is provided on the lower header 2, inserted into the T-shaped groove 201 and located below the liquid surface. A flow valve is provided on the drain pipe 3 to control its internal flow and velocity. The receiving hopper 4 is located inside the horizontal end of the T-shaped groove 201, and a drain pipe 5 is provided at the bottom of the receiving hopper 4, inserted below the liquid surface. A fixed base 6 is centrally located inside the vertical end of the T-shaped groove 201. A guide roller A7 is mounted on the fixed base 6. Two symmetrically arranged arc-shaped plates 8, rotatably connected to the fixed base 6, are arranged at its bottom. The convex surfaces of the arc-shaped plates 8 are similar, and a viewing window 203 for observing the state of the arc-shaped plates 8 is provided on the lower header 2. A guide roller B12, at the same height as the guide roller A7, is mounted on the bottom surface of the inclined groove 202. A drive assembly A is mounted on the lower header 2. In operation, the drive assembly A drives the two arc-shaped plates 8 to rotate in opposite directions. The drive assembly A includes gear 9, worm gear 10, and worm 11. An mounting shaft 81 is mounted on the arc-shaped plate 8, rotatably connected to the lower header 2 and the fixed base 6. There are two gears 9, each coaxially connected to a corresponding mounting shaft 81, meshing with it. The worm gear 10 is coaxially connected to one of the mounting shafts 81. The worm 11 is rotatably connected to the lower header 2 and meshes with the worm gear 10. A crank A is mounted at one end of the worm 11. A bracket 19 is mounted on the lower header 2. A movable plate 20 is movably mounted on the bracket 19. Two sets of pressure rollers 23 are symmetrically arranged at the bottom of the movable plate 20. Two baffles 22 are also arranged at the bottom of the movable plate 20. The two sets of pressure rollers 23 are rotatably mounted at the bottom of the corresponding baffles 22, and are positioned above the corresponding guide rollers B12. Two sets of water jet nozzles 24 are arranged between the two pressure rollers 23 at the bottom of the movable plate 20. The drive component B includes, but is not limited to, an electric telescopic rod 21. The body of the electric telescopic rod 21 is mounted on the bracket 19, and the output end of the electric telescopic rod 21 is connected to the movable plate 20. In operation, the electric telescopic rod 21 drives the movable plate 20 to rise or fall. An air guide hood 25 is located at the output end of the lower header 2. A porous heating plate 26 is installed inside the air guide hood 25. A fan 28 is mounted on the base 1. An exhaust pipe 29 is installed at the input end of the fan 28. The other end of the exhaust pipe 29 is inserted into the horizontal end of the T-shaped groove 201 and positioned above the liquid surface. The output end of the fan 28 is connected to the input end of the air guide hood 25. A drying box 27 is installed inside the air guide hood 25 between its input end and the porous heating plate 26. The drying box 27 is slidably connected to the air guide hood 25 and is filled with a desiccant, including but not limited to activated carbon packets.

[0023] In this embodiment, the fiberglass cloth passes through guide rollers B12 and A7. The electric telescopic rod 21 pushes the movable plate 20 down to the pressure rollers 23 on both sides, which, in conjunction with the corresponding guide rollers B12, clamp the fiberglass cloth, thereby reducing the gap between the T-groove 201 and the outside environment. Due to the influence of the inclined groove 202, splashed water droplets can still flow back into the T-groove 201. The water jet nozzle 24 is connected to an external water supply device, pulling the fiberglass cloth to move and starting to spray water. The water jets open the fiberglass cloth, allowing the fibers to pass through. The water flows downwards and collides with the concave surface of the arc plate 8. The arc plate 8 guides the water to both sides of the horizontal end of the T-shaped groove 201, preventing the water from directly colliding with the water in the lower header 2 and generating foam. This prevents the foam from flowing back and falling back onto the fiberglass cloth, contaminating it. When the angle of the arc plate 8 needs to be adjusted, crank A is rotated. Crank A drives the worm gear 11 to rotate, which in turn drives the arc plate 8, the mounting shaft 81, and the gear 10 to rotate. The two gears 10 mesh, so the other side of the arc plate 8 rotates in the opposite direction to the current arc plate 8. During the fiber opening process, the blower 28 and the porous electric heating plate 26 are started. The blower 28 draws air above the water surface in the T-shaped groove 201 and injects it into the air guide hood 25. After being dried and dehydrated by the desiccant, the air is heated by the porous electric heating plate 26 and blown onto the fiberglass cloth, drying it. The air flow in the T-shaped groove 201 causes water droplets to flow towards the bottom of the receiving hopper 4, further preventing water droplets from splashing everywhere.

[0024] Example 2 like Figure 1 and Figure 4 As shown, the present invention proposes an electronic-grade fiberglass cloth hydroentangling opener. Compared with Embodiment 1, a set of fixed frames 13 are respectively arranged on both sides of the lower header 2 on the base 1. Guide rollers C14 are rotatably arranged on the fixed frames 13. The guide rollers C14 and guide rollers A7 are at the same height and both are higher than the bottom surface of the inclined groove 202. A limiting mechanism for preventing the fiberglass cloth from deviating is provided on the guide rollers C14. The limiting mechanism includes a ring frame 15, a positioning ring 16, a slide 17, and a drive assembly C. The drive assembly C includes, but is not limited to, a bidirectional lead screw 18. Each guide roller C14 is fitted with two annular frames 15 that are slidably connected to it. A positioning ring 16 is rotatably set at the close end of the two annular frames 15 on the same guide roller C14. A sliding groove is provided on the base 1. Two slide frames 17 are arranged parallel to each other and slidably connected to the inner wall of the groove. A guide rod is set in the groove, and the guide rod passes through the slide frame 17 and is slidably connected to it. The two annular frames 15 on the same side of the two sets of guide rollers C14 are respectively connected to the slide frame 17 on the corresponding side. A bidirectional lead screw 18 is rotatably connected to the base 1. Two threaded sleeves are symmetrically arranged on the bidirectional lead screw 18. The two slide frames 17 are respectively connected to the threaded sleeves on the corresponding side. A crank B is set at the end of the bidirectional lead screw 18 that extends out of the base 1.

[0025] In this embodiment, when the fiberglass cloth passes over the guide roller C14, the crank B is rotated and the bidirectional lead screw 18 is rotated. The rotation of the bidirectional lead screw 18 causes the slides 17 on both sides to move closer to each other, thereby causing the ring frame 15 and the positioning ring 16 to move closer to each other synchronously. The positioning rings 16 on both sides contact the fiberglass cloth from the corresponding side, effectively preventing the fiberglass cloth from deviating during the conveying process.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
