A winding and flattening device for warping alkali-free glass fiber

Abstract

This invention discloses a winding and flattening device for warping alkali-free glass fiber, including a base plate. Support plates are provided on both sides of the top of the base plate. Sliding grooves are formed at the bottom of the two sets of support plates on their adjacent sides. Buffer receiving components are slidably arranged inside the two sets of sliding grooves. This invention uses two sets of pressure plates with different hardnesses above the winding roller. The pressure plates can be changed according to the hardness of the glass fiber. Rotating the two sets of pressure plates around a rotating rod rotates the required pressure plate downwards, above the winding roller. At this point, under the elastic force of two sets of first springs, the telescopic frame is pushed downwards, causing the pressure plates to contact the glass fiber on the surface of the winding roller, firmly pressing the glass fiber. Simultaneously, two sets of cleaning brushes are provided inside the pressure plates to wipe away dust from the surface of the glass fiber, preventing dust from being pressed into the glass fiber during winding and improving the cleanliness of the glass fiber.

Description

Technical Field

[0001] This invention relates to the field of winding and flattening devices, specifically a winding and flattening device for warping alkali-free glass fiber. Background Technology

[0002] Fiberglass roving is a plain weave fabric made of untwisted rovings and is an important base material for hand lay-up fiberglass reinforced plastics (FRP). The strength of the roving is primarily in the warp and weft directions. For applications requiring high strength in either the warp or weft, it can also be woven into a unidirectional fabric, which can have a larger number of untwisted rovings in either the warp or weft, resulting in a single warp or single weft fabric. Fiberglass cloth is widely used in hand lay-up molding processes. Fiberglass reinforced roving is mainly used in ship hulls, storage tanks, cooling towers, ships, vehicles, tank trucks, and building structural materials; therefore, the fiberglass needs to be wound up.

[0003] Current winding devices have certain shortcomings:

[0004] 1. When winding glass fiber, in order to make a tight connection between the glass fiber and the winding roller, the glass fiber is usually pressed by a pressure plate. However, the pressure plate used is the same for glass fibers with different fiber contents, which results in a poorer pressing effect when the glass fiber with higher hardness is pressed.

[0005] 2. At the same time, after the glass fiber is wound up, the winding roller needs to be disassembled and replaced. However, the existing winding roller generally needs to be fixed and installed with multiple sets of bolts and pins, which takes a lot of time during installation and disassembly, delays the work progress, and increases the workload.

[0006] 3. At the same time, when disassembling the glass fiber take-up roller, because glass fiber is heavy and the fully wound roll is heavy, if the operator is not careful when disassembling, the take-up roller may slip and fall out of the operating area, which can easily injure the operator and cause a safety accident. Summary of the Invention

A receiving plate is provided on the top of the two sets of buffer springs. First belt shafts are provided on both sides of the bidirectional threaded rod and on one side of the first gear.

[0018] Compared with the prior art, the present invention provides a winding and flattening device for warping alkali-free glass fibers, which has the following beneficial effects:

[0019] 1. This invention features two sets of pressure plates with different hardnesses above the take-up roller. The pressure plates can be changed according to the hardness of the glass fiber. Rotating the two sets of pressure plates around the rotating rod moves the desired pressure plate downwards, above the take-up roller. At this point, under the elastic force of the two sets of first springs, the telescopic frame is pushed downwards, causing the pressure plate to contact the glass fiber on the surface of the take-up roller, firmly pressing the glass fiber. Simultaneously, two sets of cleaning brushes are installed inside the pressure plates to wipe away dust from the surface of the glass fiber, preventing dust from being trapped inside the glass fiber during winding and improving the cleanliness of the glass fiber.

[0020] 2. This invention utilizes two sets of movable rectangular sleeves, allowing them to move out of the rectangular grooves on the take-up roller. This releases the rectangular sleeves from their support and transmission connection to the take-up roller. A sliding ring drives a second annular rack to move between the two sets of first gears and mesh with them. The servo motor, through the transmission of the second belt and the second belt shaft, drives the mounting plate and slide rod to rotate, causing the second annular rack to rotate. This, in turn, drives the two sets of first gears to rotate. Through transmission, the two sets of drive blocks move. The inclined sides of the drive blocks press the drive rod to move, causing the rectangular sleeves to move out of the rectangular grooves, thus enabling disassembly.

[0021] 3. The present invention provides a buffer receiving assembly at the bottom of the take-up roller, so that when the take-up roller is replaced, it falls on the receiving plate first, which squeezes the receiving plate and compresses the two sets of buffer springs, thus buffering the impact force of the take-up roller and preventing it from slipping inside the receiving plate, thus preventing the take-up roller from accidentally slipping and injuring the operator.

The appropriate pressure plate 304 can be replaced according to the specific hardness of the glass fiber.

[0034] As a preferred embodiment, the buffer receiving assembly 4 includes a base plate 401, an internal threaded sleeve 402, a hinge rod 403, a bidirectional threaded rod 404, a receiving plate 405, and a buffer spring 406. The base plate 401 is located inside the two sets of sliding grooves 8. The hinge rods 403 are hinged to both sides of the bottom of the base plate 401. The internal threaded sleeves 402 are hinged to the bottom of the two sets of hinge rods 403. The bidirectional threaded rods 404 are connected to the internal threads of the two sets of internal threaded sleeves 402. The buffer springs 406 are provided on both sides of the top of the base plate 401. The receiving plate 405 is provided on the top of the two sets of buffer springs 406. The first belt shafts 6 are provided on both sides of the bidirectional threaded rods 404 and on one side of the first gear 11. The first belts 12 are sleeved on the outer sides of the two sets of first belt shafts 6, which can buffer the disassembled take-up rollers 9.

[0035] As a preferred embodiment, the mounting groove 201 is annular and has a T-shaped cross-section to prevent the slide rod 206 from dislodging from the interior of the mounting groove 201.

[0036] As a preferred embodiment, the outer side of the ring 203 slides against the outer side of the slide bar 206, and the second gear 17 is located inside the ring 203 and meshes with the first annular rack 202, so as to facilitate meshing with the second gear 17 and the first gear 11 respectively.

[0037] As a preferred embodiment, the telescopic frame 302 consists of a set of horizontal plates and two sets of vertical bars, with the two sets of vertical bars located on both sides of the bottom of the horizontal plates, so that the components on the telescopic frame 302 can move simultaneously.

[0038] As a preferred embodiment, the take-up roller 9 has rectangular grooves on both sides, and the rectangular sleeve 19 is adapted to the rectangular grooves so that the take-up roller 9 rotates along with the rectangular sleeve 19.

[0039] As a preferred embodiment, the second drive shaft 16 is rectangular on the side near the rectangular sleeve 19, and the rectangular sleeve 19 and the second drive shaft 16 are slidably adapted to each other, so that the rectangular sleeve 19 rotates with the second drive shaft 16.

[0040] As a preferred embodiment, a limiting rod is provided at the middle position of the bottom of the receiving plate 405, and a limiting groove is provided at the middle position inside the substrate 401. The limiting rod and the limiting groove are slidably matched to prevent the receiving plate 405 from shifting.

[0041] Example 1, as Figure 1-5 As shown, during winding, the servo motor 5 is turned on and operates, driving the mounting plate 204 to rotate via the second belt 7 and the second belt shaft 14. This causes the two sets of slide rods 206 to rotate inside the mounting groove 201, which in turn causes the ring 203 to rotate. This causes the first annular rack 202 to drive the second gear 17 to rotate, and the second gear 17 to drive the second transmission shaft 16 to rotate. Since one side of the second transmission shaft 16 is rectangular, it drives the rectangular sleeve 19 to rotate, which in turn drives the winding roller 9 to rotate for winding via the rectangular groove.

[0042] Example 2, as Figure 1-5 and Figure 7 As shown, after winding is complete, the winding roller 9 needs to be disassembled. At this time, the servo motor 5 is stopped from rotating, and the ring 203 is pushed to slide on the outside of the two sets of slide bars 206, so that the ring 203 moves between the two sets of first gears 11, and the second ring rack 205 meshes with the two sets of first gears 11. Then, the servo motor 5 is turned on to rotate, driving the two sets of first gears 11 to rotate. Through the transmission of the turntable 10 and the first transmission shaft 15, the two sets of drive blocks 22 make circumferential motion. The inclined side of the drive block 22 presses the drive rod 18 to move, and the two sets of... The drive rod 18 moves, causing the rectangular sleeve 19 to slide outside the second transmission shaft 16, moving the rectangular sleeve 19 out of the rectangular groove for disassembly. At the same time, a set of first gears 11 drives the bidirectional threaded rod 404 to rotate through the transmission of the first belt shaft 6 and the first belt 12, causing the two sets of internal threaded sleeves 402 to move closer to each other. The two sets of hinge rods 403 push the base plate 401 upward, causing the receiving plate 405 to contact the take-up roller 9. When the take-up roller 9 falls, it is buffered, so that the take-up roller 9 falls stably inside the receiving plate 405 and is not easy to fall off.

[0043] Working principle: Rotating the two sets of pressure plates 304 around the rotating rod 306 can rotate the required pressure plate 304 to the lower position, that is, above the take-up roller 9. At this time, under the elastic force of the two sets of first springs 303, the telescopic frame 302 is pushed downward as a whole, causing the pressure plate 304 to come into contact with the glass fiber on the surface of the take-up roller 9, and firmly pressing the glass fiber. At the same time, two sets of cleaning brushes 305 are set inside the pressure plate 304, which can wipe the dust on the surface of the glass fiber, preventing the dust from being pressed into the glass fiber during the winding process, thus improving the cleanliness of the glass fiber.

[0044] The sliding ring 203 drives the second annular rack 205 to move between the two sets of first gears 11 and mesh with each other. This causes the servo motor 5 to drive the mounting plate 204 and slide rod 206 to rotate through the transmission of the second belt 7 and the second belt shaft 14. This causes the second annular rack 205 to rotate, which in turn drives the two sets of first gears 11 to rotate. Through the transmission of the turntable 10 and the first transmission shaft 15, the two sets of drive blocks 22 make circular motion. The inclined side of the drive block 22 presses the drive rod 18 to move. The movement of the two sets of drive rods 18 causes the rectangular sleeve 19 to slide on the outside of the second transmission shaft 16, moving the rectangular sleeve 19 out of the rectangular groove, so that it can be disassembled.

[0045] When the take-up roller 9 is being replaced, it first falls above the receiving plate 405, which compresses the receiving plate 405 and compresses the two sets of buffer springs 406, thus buffering the impact force of the take-up roller 9 and preventing it from slipping inside the receiving plate 405, thus preventing the take-up roller 9 from accidentally slipping and injuring the operator.

[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
