[0003] 1. Steel welded yarn hanging disc: This type of yarn hanging disc is sintered by electric welding from a steel disc and steel nails. However, the spacing of its yarn hanging needles often appears uneven, resulting in poor yarn dropping accuracy, and further causing inconsistent wall thickness of the product and difficult tolerance control. In addition, after being discarded, due to its material and structural characteristics, it is difficult to recycle and reuse, and incineration treatment will cause serious pollution to the environment.

[0004] 2. Steel strip and wood laminated yarn hanging disc: This design is formed by crimping a steel strip with steel nails and a wood laminated disc, effectively solving the problem of uneven spacing of yarn hanging needles and ensuring the wall thickness uniformity of the wound product. However, its operation of changing specifications is complex, the cost is relatively high, and it also faces the problems of difficult recycling and environmental protection treatment after being discarded.

[0005] 3. Resin casting mold yarn hanging disc: This type of yarn hanging disc is formed by resin casting, and its manufacturing process is similar to the sand casting process, and it can be accurately replicated according to the sample parts. Although the manufacturing accuracy has been improved, it is still a disposable product in the end, and it cannot be effectively recycled after being discarded, and incineration treatment will pose a threat to the environment.

[0006] Currently, while the above three yarn hanging disc solutions improve the product quality, they all face the severe challenges of environmental protection recycling and treatment. Therefore, exploring new yarn hanging disc materials and technologies that are recyclable and low-pollution is of great significance for promoting the green and sustainable development of the fiberglass resin-impregnated winding processing industry.

[0030] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0031] A glass fiber impregnated resin wound rod recyclable yarn hanging disk according to an embodiment of the present utility model will be described below with reference to the drawings.

[0032] As Figures 1-5 shown, a glass fiber impregnated resin wound rod recyclable yarn hanging disk according to an embodiment of the present utility model includes a yarn hanging needle 1, a steel mother disk 2 and a steel pressing disk 3. Among them, the yarn hanging needle 1 is made of a hard engineering plastic such as PP, ABS or PU, and has a propeller shape, and is divided into a long specification and a short specification. The steel mother disk 2 is provided with a plurality of card slots 5 on its circumference. The number and positions of the plurality of card slots 5 are set according to the outer diameter of the small end of the winding shaft and the number of laying yarns, and are determined by equally dividing the arc length of the outer circumference of the steel mother disk 2 by 120 degrees. The plurality of card slots 5 axially penetrate to form a trapezoidal cavity, and the steel pressing disk 3 cooperates with the steel mother disk 2.

[0033] Among them, it can be understood that the material selection of the yarn hanging needle 1: The yarn hanging needle 1 is made of a hard engineering plastic formed by composite material injection molding, such as polypropylene PP, acrylonitrile-butadiene-styrene copolymer ABS or polyurethane PU. These materials have excellent mechanical strength, wear resistance and corrosion resistance, and can withstand the tension generated during the yarn laying process without being easily deformed or broken.

[0034] Outer shape design: The outer shape of the yarn hanging needle 1 is designed as a propeller shape. This design not only increases the contact area between the yarn hanging needle 1 and the yarn, improves the yarn grasping ability, but also enables the yarn to be evenly distributed during the winding process, avoiding stacking or loosening phenomena. At the same time, the propeller shape design also facilitates the smooth introduction and export of the yarn, reducing the risk of yarn breakage.

[0035] Specification Classification: According to the requirements of the large and small ends of the winding shaft, the yarn hanging needles 1 are divided into long specifications and short specifications. The long-specification yarn hanging needles 1 are applicable to the small-end part of the winding shaft, and their length and shape are precisely calculated to ensure that the yarn can closely adhere to the surface of the winding shaft; while the short-specification yarn hanging needles 1 are used for the large-end part of the winding shaft, and their design is more compact to adapt to the special shape and size requirements of the large-end part.

[0036] The steel master disc 2 is made of 45# steel, which has high strength and toughness and can meet the requirements of the yarn hanging device for rigidity and durability.

[0037] Card Slot Design: A plurality of card slots 5 are evenly distributed on the circumference of the steel master disc 2. The number and position of the card slots 5 are precisely designed according to the outer diameter of the small end of the winding shaft and the number of yarn laying strips. The positions of the card slots 5 are determined by equally dividing the arc length of the outer circumference of the 120-degree master disc to ensure that each card slot 5 can accurately correspond to a yarn laying point on the winding shaft. The card slots 5 axially penetrate to form a trapezoidal cavity. This design not only facilitates the insertion and fixation of the yarn hanging needles 1 but also provides sufficient space during disassembly to reduce the disassembly difficulty.

[0038] The steel pressure disc 3 is closely fitted with the steel master disc 2, and the yarn hanging needles 1 are fastened by passing fastening screws through the fastening countersunk screw holes 6 or fastening screw holes 7. The design of the steel pressure disc 3 ensures the stability and reliability of the yarn hanging needles 1 during the working process, preventing loosening or falling off due to vibration or impact.

[0039] During the installation process, first select the appropriate specifications and quantities of the yarn hanging needles 1 according to the size of the winding shaft and the yarn laying requirements, and insert them into the corresponding card slots 5 of the steel master disc 2. Then, place the steel pressure disc 3 above the steel master disc 2 and fix it to the steel master disc 2 with fastening screws. Finally, debug and check the entire device to ensure that all components are in normal working condition.

[0040] In an embodiment of the present utility model, as Figures 1-3 shown, it further includes multiple groups of carrying cabins 21 and rabbets 31. Among them, multiple groups of carrying cabins 21 are respectively arranged on both sides of the steel master disc 2, and the rabbets 31 are arranged on the circumference of the steel master disc 2. The depth of the rabbets 31 is 4 mm and the width is 6 mm.

[0041] Among them, it can be understood that multiple carrying cabins 21 are arranged on both sides of the steel mother plate 2, avoiding interference with the yarn hanging needles 1 and other components, ensuring that during the entire winding process, the carrying cabins 21 can stably support and assist the operation of the yarn hanging needles 1. The main design purpose of the multiple carrying cabins 21 is to assist in the installation and disassembly process of the yarn hanging needles 1. Before the yarn hanging operation starts, the operator can easily install the yarn hanging needles 1 at the designated positions on the steel mother plate 2 by utilizing the support and guiding functions provided by the carrying cabins 21. Similarly, after the operation is completed or when the yarn hanging needles 1 need to be replaced, the carrying cabins 21 can also effectively help the operator quickly and accurately complete the disassembly work. This design not only improves the operation efficiency but also reduces the labor intensity of the operator.

[0042] The rabbet 31 is arranged on the circumference of the steel mother plate 2, and its position and quantity are precisely calculated according to the layout and quantity of the yarn hanging needles 1. The rabbet 31 has a specific depth and width: the depth is 4 mm and the width is 6 mm. The design of the rabbet 31 is mainly used to further optimize the installation and fixing effects of the yarn hanging needles 1. By providing precise positioning and fixing spaces, the rabbet 31 can ensure that the yarn hanging needles 1 maintain the correct positions and postures during the installation process. At the same time, during the winding process, the rabbet 31 can also play a role in dispersing stress and reducing vibration, thereby improving the overall stability and reliability of the device.

[0043] In an embodiment of the present utility model, as Figures 1-3 shown, fastening countersunk screw holes 6 or fastening screw holes 7 are evenly distributed on the stepped hole surface of the steel mother plate 2.

[0044] Among them, it can be understood that the main functions of the fastening countersunk screw holes 6 and the fastening screw holes 7 are to fix the steel pressure plate 3 and the yarn hanging needles 1 by installing fastening screws or bolts. During the winding process, the yarn hanging needles 1 need to bear the tension and vibration from the yarn, so it is necessary to ensure that the connection between it and the steel mother plate 2 is firm and reliable. By installing fastening screws or bolts in these holes, the yarn hanging needles 1 and the steel pressure plate 3 can be effectively fastened to the steel mother plate 2 to prevent them from loosening or falling off.

[0045] In an embodiment of the present utility model, as Figure 1 shown, the yarn hanging needles 1 are movably connected to multiple card slots 5.

[0046] Among them, it can be understood that during the actual use process, when the steel mother plate 2 and the steel pressure plate 3 reach a certain degree of wear or need to be replaced, they can be disassembled from the yarn hanging device for necessary cleaning, maintenance, and replacement of worn components. After being repaired, the steel mother plate 2 and the steel pressure plate 3 can be reinstalled on the yarn hanging device for continued use, thus achieving the purpose of cyclic turnover use. This design not only reduces the production cost but also reduces resource waste and environmental pollution.

[0047] In an embodiment of the present utility model, as Figure 1 shown, it further includes a countersunk head screw 4, and the countersunk head screw 4 is movably arranged on the steel pressure plate 3 and the steel master plate 2.

[0048] Among them, it can be understood that when the countersunk head screw 4 passes through the fastening countersunk head screw hole 6 and is screwed into the steel pressure plate 3, through the locking action of the thread, the steel pressure plate 3 is firmly fixed on the steel master plate 2. This fixing method not only ensures the stability of the yarn hanging needle 1 during high-speed rotation or under large tension, but also prevents loosening or falling off caused by vibration or impact.

[0049] Specifically, in the actual implementation process:

[0053] 3. Check whether all accessories are intact, especially whether the fastening countersunk head screw holes 6 or fastening screw holes 7 on the yarn hanging needle 1 and the steel master plate 2 are clear and unblocked.

[0054] Install the yarn hanging needle:

[0055] 1. Place the steel master plate 2 on a suitable workbench to ensure its stability and non-slip.

[0056] 2. According to the position of the card slot 5 on the steel master plate 2, insert the long-specification yarn hanging needles 1 one by one into the corresponding card slots 5 at the small end, ensuring that the yarn hanging needles 1 are tightly fitted with the card slots 5 without looseness.

[0057] 3. Similarly, insert the short-specification yarn hanging needles 1 into the corresponding card slots 5 at the large end, paying attention to the direction and angle of the yarn hanging needles 1 to ensure that they can smoothly guide the yarn during the winding process.

[0058] Fasten the pressure plate:

[0059] 1. Place the steel pressure plate 3 above the steel master plate 2 on which the yarn hanging needles 1 have been installed, ensuring that the hole positions on the steel pressure plate 3 correspond one by one to the fastening countersunk head screw holes 6 or fastening screw holes 7 on the steel master plate 2.

[0060] 2. Use fastening screws, and fasten them through the holes on the steel female plate 2 and the steel pressure plate 3. During the fastening process, gradually apply force evenly to avoid damage or deformation of the components caused by over-tightening at one time.

[0061] 3. Check whether all the fastening screws have been tightened in place to ensure that there is no gap between the steel female plate 2 and the steel pressure plate 3, and the yarn hanging needle 1 is firmly fixed in the card slot 5.

[0062] In summary, for the recyclable and renewable yarn hanging disc of the fiberglass resin-impregnated winding rod in the embodiment of the present utility model, based on the outer diameter of the small end of the winding shaft, the positions of the yarn hanging needles are accurately allocated to ensure uniform wall thickness and improve product quality.
