Description

Technical Field

[0001] The utility model belongs to the field of wire guide devices, in particular to a fiber band-shaped bundled winding wire guide device. Background Art

[0002] Currently, the winding industry is widely used in defense and civilian applications, such as the production of rocket engine casings, missile launch tubes, pressure vessels, and municipal pipelines. These products offer advantages such as light weight, high strength, rust resistance, corrosion resistance, low thermal expansion coefficient, and long service life. Most CNC winding machines utilize a main shaft and winding nozzle to wind multiple strands of fiber onto a core mold in the form of a cloth strip or round rod. To ensure that the fibers are flat, evenly and continuously distributed across the core mold surface according to a specific pattern during winding, the relative motion relationship between the core mold and winding head must be determined and the winding pattern established. Advanced and rational fiber bundling guides are also required. Existing fiber bundling guides typically utilize a combination of the upper and lower inner curved surfaces of two circular rings (tubes) or the upper and lower outer curved surfaces of two rollers. This structural design allows the fiber bundle to transition from a lower guide head with an upward-facing arc to an upper guide head with a downward-facing arc, where it is gathered and tightened. After passing through the two wire guides, the fiber bundle changes according to the shape of the wire surface, making the fiber bundle uneven, the tightness of each fiber strand different, and the tension different, which seriously affects the quality of the wound product.

[0003] In order to ensure high-precision winding quality, it is crucial to make innovative designs on the wire guide device to bundle multiple strands of fibers into the shape required for winding, ensure smooth and even pay-off, and ensure that the tension of each strand of yarn is consistent. Utility Model Content

[0004] The purpose of this utility model is to provide a fiber ribbon bundle winding guide wire device to solve the problems of kinking and uneven tightness that occur when winding multiple strands of fiber ribbons, resulting in poor quality of the wound product. It can evenly and continuously cover the core mold according to a set pattern, and the payout is smooth and flat, with the tension of each strand of fiber being basically consistent.

[0005] In order to solve the above problems, the utility model discloses a fiber band bundle winding guide wire device, comprising an upper limit guide wire head, a lower limit guide wire head and a comb-shaped guide wire head arranged in sequence; the upper limit guide wire head comprises a first arc bent rod, a first connecting plate and a first support rod, the first arc bent rod is arranged at the upper part of the first connecting plate, and the first support rod is arranged at the lower part of the first connecting plate; the lower limit guide wire head comprises a second arc bent rod, a second connecting plate and a second support rod, the second arc bent rod is arranged at the upper part of the second connecting plate, and the second support rod is arranged at the lower part of the second connecting plate; the radius of the first arc bent rod is smaller than the radius of the second arc bent rod, and the vertex of the second arc bent rod is lower than the vertex of the first arc bent rod.

[0006] As a further improvement of the above technical solution:

[0007] The comb-shaped wire guide head includes a comb finger rod, a comb seat and a third support rod. The comb finger rods are evenly distributed on the comb seat, and the third support rod is arranged below the comb seat.

[0008] The inner surface of the first arc curved rod is a smooth structure, the outer surface of the second arc curved rod is a smooth structure, and the comb finger rod is a cylindrical structure with a smooth surface.

[0009] It also includes a support, and the upper limit wire guide head, lower limit wire guide head and comb-shaped wire guide head are installed on the support. The support includes a support rod, a rib plate and a fixed plate. The support rod is connected to the fixed plate. The rib plate is arranged on one side of the support rod and is connected to the fixed plate to strengthen the connection strength between the support rod and the fixed plate.

[0010] The support rod is provided with a plurality of through holes for installing the first support rod, the second support rod and the third support rod. The through holes are provided with locking holes perpendicular thereto, and the locking holes are provided with set screws.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The fiber band-shaped bundle winding guide wire device of the utility model has a novel and ingenious design, a simple structure and a low manufacturing cost. Disassembly, assembly, debugging, maintenance and cleaning operations are convenient and quick. The combined use of multiple guide wire heads can not only ensure that each strand of fiber is evenly arranged at an equidistant distance to prevent kinking, but also enable them to be quickly bundled and gathered. Moreover, the cross-sectional shape changes little after passing through each guide wire head, the pay-off is smooth and flat, the fiber wear is small, and the tension changes little, which greatly improves the winding quality. Especially for wet winding, the arc of the guide wire head passing through the line faces downward, and excess glue is not easy to accumulate on the guide wire head, which reduces the number of times the guide wire head is cleaned and improves work efficiency. The combined design of the guide wire heads forms a closed crescent shape in the running area of ​​the fiber bundle, so that the fiber bundle is not easy to run off the yarn during the winding process, and it is safe and reliable to use.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, the fiber strip bundle winding guide wire device of this embodiment includes an upper limit guide wire head 1, a lower limit guide wire head 2 and a comb-shaped guide wire head 3 arranged in sequence; it also includes a support 5, and the upper limit guide wire head 1, the lower limit guide wire head 2 and the comb-shaped guide wire head 3 are installed on the support 5.

[0028] like Figures 7 to 9 As shown, the support 5 includes a support rod 15, a rib plate 16 and a fixed plate 17. The support rod 15 is connected to the fixed plate 17. The rib plate 16 is arranged on one side of the support rod 15 and is connected to the fixed plate 17 to strengthen the connection strength between the support rod 15 and the fixed plate 17. The support rod 15 is similar to a stepped shaft, and the large shaft section has two symmetrically milled planes. Three circular through holes in vertical planes are drilled in sequence at the far end of the cantilever. A threaded hole is machined in the center of one side of the vertical circular through hole, and the set screw 4 is screwed thereto. The small shaft section is inserted into the middle circular through hole of the fixed plate 17 so that the two planes of the large shaft are parallel to the axis of the upper and lower sets of mounting holes of the fixed plate 17, and the head is slightly lower than the outer surface of the fixed plate 17. The fixed plate 17 is machined with 4 circular through holes for device installation.

[0029] The support rod 15 is provided with several through-holes for mounting the first support rod 8, the second support rod 11, and the third support rod 14. The through-holes are provided with perpendicular locking holes, each of which is equipped with a set screw 4. The support rods of the upper limit wire guide head 1, the lower limit wire guide head 2, and the comb-shaped wire guide head 3 are sequentially inserted into the through-holes of the support 5. The vertical range of the yarn movement is adjusted by fine-tuning the support rod height. After the height of each wire guide head is adjusted, the set screw 4 is screwed into the locking hole on the side of the support 5 to tighten the support rod. The device is then screwed through the four circular holes in the support 5 to the winding machine's winding head, and it feeds and rotates with the winding head. The comb-shaped wire guide head 3 is comb-shaped, with the comb fingers evenly spaced. Both the upper limit wire guide head 1 and the lower limit wire guide head 2 are circular arcs with the arc center facing downward. The upper limit wire guide head 1 has a smaller arc radius, while the lower limit wire guide head 2 has a larger arc radius. Each fiber passing through the winding nozzle first passes through the comb-like guide head 3, where it is flattened between adjacent comb fingers, restricting left and right movement of the yarn and ensuring uniform spacing. The fibers then pass to the lower limit guide head 2, where they cling to its outer arc surface, slightly converging the left and right spacing and restricting downward movement, thus serving as a transition for the upper limit guide head 1 to gather them. Then, at the upper limit guide head 1, the fibers cling to its inner arc surface, gathering and tightening them, and restricting upward movement. Under the combined action of these three guide heads, each strand of fiber naturally and smoothly gathers and gradually forms a ribbon-like payout.

[0030] like Figure 4 As shown, the upper limit wire guide head 1 includes a first arc bent rod 6, a first connecting plate 7 and a first support rod 8, all of which are made of stainless steel. The first arc bent rod 6 is arranged on the upper part of the first connecting plate 7, and the first support rod 8 is arranged on the lower part of the first connecting plate 7. The first arc bent rod 6 is bent by round steel, and the arc radius is relatively small. The two ends of the first arc bent rod 6 are milled and then symmetrically welded to the two ends of the first connecting plate 7. The first support rod 8 is a stepped shaft, and the small shaft section is inserted into the hole in the center of the first connecting plate 7, and its head is slightly lower than the upper surface of the first connecting plate 7. The connection between the shoulder of the first support rod 8 and the lower surface of the first connecting plate 7 is then firmly welded. The inner surface of the arc of the first arc bent rod 6 is very smooth to reduce wear on the yarn.

[0031] like Figure 5 As shown, the lower limit wire guide head 2 includes a second arc bent rod 9, a second connecting plate 10 and a second support rod 11, all of which are made of stainless steel. The second arc bent rod 9 is arranged on the upper part of the second connecting plate 10, and the second support rod 11 is arranged on the lower part of the second connecting plate 10; the radius of the first arc bent rod 6 is smaller than the radius of the second arc bent rod 9, and the vertex of the second arc bent rod 9 is lower than the vertex of the first arc bent rod 6. The second arc bent rod 9 is bent by bending round steel, and the arc radius is relatively large. After the two ends of the second arc bent rod 9 are milled, they are symmetrically welded to the lower step surfaces at both ends of the second connecting plate 10. The second support rod 11 is a stepped shaft, and the small shaft section is inserted into the hole in the center of the second connecting plate 10, and its head is slightly lower than the upper surface of the second connecting plate 10. The connection between the shoulder of the second support rod 11 and the lower surface of the second connecting plate 10 is then firmly welded. The outer surface of the arc of the second arc bent rod 9 is very smooth to reduce wear on the yarn.

[0032] like Figure 6 As shown, the comb-shaped wire guide head 3 includes comb fingers 12, a comb base 13, and a third support rod 14, all made of stainless steel. The comb fingers 12 are evenly distributed on the comb base 13, and the third support rod 14 is located below the comb base 13. The comb fingers 12 are small, smooth, uniformly sized round rods that act as wire guides. After being coated with glue, they are inserted and secured into equally spaced blind holes at the top of the comb base 13. The third support rod 14 and the comb base 13 are made of round steel of the same diameter. The third support rod 14 is welded vertically and centered to the bottom of the comb base 13, forming a T-shape.

[0033] The method for using the fiber ribbon bundle winding guidewire device of this embodiment includes the following steps:

[0034] S1, pass each strand of fiber from the winding machine's winding nozzle through the comb-shaped wire guide head 3, the lower limit wire guide head 2 and the upper limit wire guide head 1 in sequence, and then fix the thread ends on the winding machine's main shaft core mold;

[0035] S2. Set the tension of the fiber bundle, adjust the position of the winding machine's winding head and the height of the comb-shaped guide head 3, the lower limit guide head 2 and the upper limit guide head 1, so that the fibers are in a tightened state, and each fiber is symmetrically laid side by side between adjacent comb fingers of the comb-shaped guide head 3 at equal distances, tangent to the outer side of the comb finger rod 12, and is gradually gathered and transitioned to the upper limit guide head 1 through the outer arc surface of the second arc bent rod 9 of the lower limit guide head 2, and is bundled and tightened into a strip through the inner arc surface of the first arc bent rod 6 of the upper limit guide head 1.

[0036] The appropriate winding equipment and process are selected based on the strength and rigidity requirements of the product structure. The relative motion between the core mold and the winding head allows the fiber bundle to be evenly and continuously spread over the core mold surface according to a certain pattern until the core mold winding is completed.

[0037] The utility model can ensure that each strand of fiber is evenly and evenly arranged to prevent kinking through the combined use of multiple wire guides, and can also quickly gather and bunch them. Moreover, the cross-sectional shape changes little after passing through each wire guide, the pay-off is smooth and flat, the fiber wear is small, and the tension changes little, which greatly improves the winding quality. Especially for wet winding, the arc of the wire guide surface is facing downward, and excess glue is not easy to accumulate on the wire guide, which reduces the number of times the wire guide is cleaned and improves work efficiency. The combined design of the wire guides forms a closed crescent shape in the running area of ​​the fiber bundle, making it difficult for the fiber bundle to run off during the winding process, and it is safe and reliable to use.
