Description

Technical Field

[0001] This utility model belongs to the technical field of polyester monofilament winding equipment, specifically relating to polyester monofilament trays. Background Technology

[0002] Polyester monofilament is a single fiber made of polyester (PET) material. It features high strength, high elasticity, abrasion resistance, light resistance, aging resistance, strong UV resistance, excellent acid and alkali resistance, and antibacterial properties. In addition, polyester monofilament is non-hygroscopic, non-conductive, and rust-free, allowing it to maintain stable performance in various environments.

[0003] Polyester monofilaments are generally distinguished by their fiber diameter, which offers a wide range to meet the needs of various fields. Common polyester monofilament colors include black, transparent, and green. Furthermore, depending on the production process and application, polyester monofilaments can be classified into various types, such as colored, fluorescent, surface-modified (e.g., antistatic, conductive, silicon nitride), and composite (core-sheath, thermally bonded) products.

[0004] After the polyester monofilament is produced, the tray is rotated by the shaft of the winding equipment. At this time, the shaft passes through the center hole of the tray, so that the polyester monofilament is wound on the tray, and then the trays containing polyester monofilament are stored together.

[0005] Existing technology uses one-piece injection molding for pallets, resulting in a single size for the center hole. When the diameter of the center hole of the pallet is different from the diameter of the shaft of the winding equipment, the pallet cannot be installed on the shaft. Utility Model Content

[0006] The purpose of this invention is to solve the aforementioned technical problems in the prior art by providing a polyester monofilament tray that allows for detachable connection between the center rod assembly and the tray housing. This allows for the selection of a center rod assembly with the required center hole size, thus broadening the applicability of the polyester monofilament tray. Furthermore, when the center hole is damaged, replacing it with a new center rod assembly ensures the integrity of the center hole structure and guarantees normal winding of the polyester monofilament.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0033] a-Center hole. Detailed Implementation

[0034] like Figures 1 to 10 As shown, this is a polyester monofilament tray of the present invention. After the polyester monofilament is produced, it is wound onto the tray to obtain a tray containing polyester monofilament.

[0035] The polyester monofilament pallet includes a pallet shell 1 and a central rod assembly 2. The pallet shell 1 is a one-piece molded structure, comprising support columns 11 and discs 12. The discs 12 are respectively disposed at both ends of the support columns 11, and the cross-sectional area of ​​the discs 12 is larger than that of the support columns 11. Polyester monofilaments are wound on the support columns 11, and simultaneously wound in the space between the two discs 12, ensuring the quality of the polyester monofilament winding. The discs 12 are provided with stiffening ribs 18, which are arranged crosswise and form grooves 19. The reasonable arrangement of the stiffening ribs 18 can reduce the overall weight of the discs 12 while ensuring the strength of the discs 12, facilitating the handling and transportation of the polyester monofilament pallet, and also reducing material costs.

[0036] The tray housing 1 has a through mounting hole 13, and the center rod assembly 2 is disposed in the mounting hole 13.

[0037] The center rod assembly 2 and the tray housing 1 are detachably connected. Specifically, the center rod assembly 2 includes a center rod 21, an end cap 22, and an end cap 23. The center rod 21 has an end cap 25 and an end cap 26. The end cap 22 is fixed at the end cap 25 of the center rod 21. The end cap 22 and the center rod 21 can be integrally formed. The inner wall of the mounting hole 13 is provided with a ring-shaped limiting protrusion 14 and a ring-shaped limiting protrusion 15. The end cap 23 is provided with a threaded hole 219. The end cap 26 is provided with a connecting part 28. A stiffening plate 210 is provided between the connecting part 28 and the center rod 21 to increase the load-bearing capacity of the connecting part 28. The cross-sectional area of ​​the connecting part 28 is larger than that of the end cap 26. The connecting part 28 is provided with a threaded hole 29. The threaded hole 219 and the threaded hole 29 are threadedly connected to a threaded post 214, so that the end cap 23 can be detachably connected to the end cap 26. The center rod 21 has a through hole 27, and the end cap 23 has a through hole 218. The through hole 218 and the through hole 27 are connected to form a through center hole a, through which the shaft of the winding equipment passes. The end cap 22 has a connecting post 211, and a stiffening plate 212 is provided between the end cap 22 and the connecting post 211 to increase the connection strength between the end cap 22 and the connecting post 211 and prevent the connecting post 211 from being damaged. The limiting protrusion 14 has a connecting post 16, and the connecting post 16 has a connecting hole 17. When installing the center rod assembly 2, the connecting post 211 is placed in the connecting hole 17, and the end cap 22 is limited at the limiting protrusion 14. Then, the end cap 23 is installed on the end cap 26 through the threaded post 214, and the end cap 23 is limited at the limiting protrusion 15. At this time, the limiting protrusion 14 and the limiting protrusion 15 are located in the area between the end cap 22 and the end cap 23, so that the center rod assembly 2 can be installed in the mounting hole 13. When the threaded post 214 is unscrewed, the end cap 23 can be removed, and then the end cap 22 and the center rod 21 of the whole structure can be taken out, so that the center rod assembly 2 can be taken out from the mounting hole 13. The center rod assembly of the design specification can be selected according to the required size of the center hole, so that the polyester monofilament tray has a wide range of applications. By adjusting the diameter of the center hole, the winding equipment can adapt to the production needs of polyester monofilaments of different diameters and meet the customized needs of different customers. At the same time, it ensures that the polyester monofilaments can be wound smoothly and stably onto the support column, avoiding problems such as jamming and breakage caused by diameter mismatch. Moreover, when the center hole is damaged, a new center rod assembly is used to ensure the integrity of the center hole structure and to ensure normal winding of the polyester monofilaments.

[0038] End cap 23 is provided with connecting post 3 215, and magnet 1 220 is provided in connecting post 3 215. End cap 24 is provided with connecting post 4 216, and magnet 221 is provided in connecting post 4 216. Magnet 221 and magnet 1 220 attract each other, so that end cap 24 can be detachably connected to end cap 23. End cap 24 is provided in mounting hole 13 and has connecting hole 222. End cap 23 is provided with limiting part 217, which is provided in connecting hole 222. End cap 24 is used to cover threaded post 214, so that the connection between end cap 23 and end cap 26 is hidden, and the threaded post 214 is prevented from loosening due to external influence.

[0039] To improve aesthetics, the end face of end cap 22 is flush with the end face of one of the discs 12, and the end face of end cap 24 is flush with the end face of the other disc 12. Both end cap 22 and end cap 24 are provided with end cap holes 213. By applying force to the end cap holes 213, end cap 22 and end cap 24 can be easily removed from the mounting holes 13.
