Technical Field
[0001] This utility model relates to a finished yarn stacking and positioning structure and a finished yarn pallet packaging structure. Background Technology
[0002] Finished yarns need to be stacked layer by layer on pallets during shipment. Since the finished yarns consist of a core tube and yarn wound around it to form a cylindrical shape, directly stacking them is unstable. Therefore, plastic positioning shelves are needed for each layer. Currently, these plastic positioning shelves are integrally injection molded from plastic, mainly consisting of the shelf itself and positioning tubes integrally injection molded onto its upper and lower surfaces. However, these plastic positioning shelves are customized according to the diameter of the finished yarns required by different customers. Once manufactured, they cannot be changed, resulting in the need to customize many different types of plastic positioning shelves. Customizing plastic positioning shelves not only incurs mold costs and has a long mold production cycle, but also has a high cost per shelf. When these finished yarns are shipped and the plastic positioning shelves cannot be recycled, it results in significant cost expenditures. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a finished yarn stacking and positioning structure. This finished yarn stacking and positioning structure is reasonably designed and helps to reduce manufacturing costs and production cycle.
[0004] The present invention relates to a finished yarn stacking and positioning structure, characterized in that: it includes a thin plate and a plurality of plastic positioning discs arranged in a matrix on at least one side surface of the thin plate. The plastic positioning discs include a conical tube body for positioning the inner circumferential wall of the finished yarn core tube and a base plate integrally formed at the lower end of the tube body. The center of the base plate is locked to the thin plate body by bolts.
[0005] Preferably, the aforementioned thin sheet is a PVC plastic sheet, KT board, or PVC board.
[0006] Preferably, the base plate includes a circular piece and multiple connecting ribs connecting the circular piece and the inner wall of the tube. The circular piece has a through hole in its center, and the bolt passes through the through hole to connect and fix the plastic positioning plate to the thin plate.
[0007] Preferably, the upper surface of the thin sheet is provided with a plurality of plastic positioning discs, and the lower surface of the thin sheet is provided with four plastic positioning discs, which correspond to the four corners of the plastic positioning discs on the upper surface of the thin sheet.
[0008] Preferably, multiple plastic positioning discs are arranged in a matrix on both the upper and lower surfaces of the thin sheet, with the plastic positioning discs on the upper and lower surfaces of the thin sheet facing each other one-to-one.
[0009] The method for manufacturing the finished yarn stacking and positioning structure of this utility model involves purchasing common thin sheets (such as PVC plastic sheets, KT boards, or PVC boards) and cutting them into sheets of the same length and width according to the pallet size. Then, markings for the mounting screws are set according to the outer diameter of the finished yarn. Finally, pre-made plastic positioning discs are bolted to the marked positions on the thin sheets, thus completing the manufacturing process.
[0010] The advantages of this utility model's finished yarn stacking and positioning structure are: because it uses commonly used thin plates (such as PVC plastic plates, KT boards, or PVC boards), and plastic positioning plates can be installed on the thin plate matrix according to the finished yarns of different sizes, the cost and production cycle of mold making can be reduced, and the materials are readily available and low in cost.
[0011] The finished yarn stacking and positioning structure of this utility model is characterized by: including a stacking plate and multiple layers of finished yarns stacked on the stacking plate and multiple layers of the above-mentioned finished yarn stacking and positioning structure, wherein each finished yarn in each layer of finished yarns is fitted onto a plastic positioning plate.
[0012] Preferably, a tightening strap is bound between the thin sheet in the top layer of the finished yarn stacking and positioning structure and the lower surface of the upper plate of the pallet.
[0013] The finished yarn stacking and positioning structure of this utility model achieves the advantages of low manufacturing cost and convenient manufacturing due to the adoption of the above-mentioned finished yarn stacking and positioning structure. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] The finished yarn stacking and positioning structure of this utility model includes a thin plate 1 (the thin plate is made of PVC plastic board, KT board or PVC board, etc., which are commonly used boards on the market, cheap and easy to obtain) and a plurality of plastic positioning discs 2 arranged in a matrix on one or both sides of the thin plate (i.e. the upper or lower surface, or the upper and lower surfaces), the plastic positioning discs 2 being prefabricated.
[0022] PVC plastic sheets have a honeycomb-like mesh cross-section, forming a continuous porous structure similar to a honeycomb; KT sheets have a polystyrene (PS) foam core as the core, with a PVC film or paper covering the surface; PVC foam sheets have a high-pressure polyethylene (EVA) foam core as the base, with a PVC board or film covering the surface. These thin sheets are 2-4 mm thick. Although their strength is lower than that of integrally molded plastic sheets, they are not affected in use in palletized packaging because the upper and lower layers of finished yarns support each other.
[0023] The plastic positioning plate 2 includes a conical tube 3 for positioning the inner circumferential wall of the finished yarn core tube and a base plate 4 integrally formed at the lower end of the tube. The center of the base plate is locked to the thin plate 1 by bolts 5 (or screws).
[0024] The finished yarn consists of a core tube and yarn wound around the core tube. Regardless of the specification of the finished yarn, the size of the core tube is the same. Therefore, the plastic positioning discs 2 are all components of the same size. The significant advantage of this application is that the spacing between adjacent plastic positioning discs 2 can be adjusted as needed.
[0025] Although the spacing between adjacent positioning tubes on the existing one-piece injection-molded plastic positioning plate can be set to the size of the largest specification finished yarn, which can meet the packaging of most specifications of finished yarn, it results in wasted space and increased transportation costs when packaging small-sized finished yarn.
[0026] The base plate 4 includes a circular piece 6 and multiple connecting ribs 7 connecting the circular piece and the inner wall of the tube. The circular piece has a through hole 8 in the center, and the bolts 5 (or screws) are inserted through the through hole to connect and fix the plastic positioning plate to the thin plate. The wall thickness of the circular piece 6 and the connecting ribs 7 is the same as or close to the wall thickness of the tube 3, so as to facilitate integral injection molding.
[0027] In one embodiment, the upper surface of the thin sheet 1 is provided with a plurality of plastic positioning discs 2, and the lower surface of the thin sheet is provided with four plastic positioning discs, which correspond to the four corners of the plastic positioning discs on the upper surface of the thin sheet.
[0028] In another embodiment, multiple plastic positioning discs 2 are arranged in a matrix on both the upper and lower surfaces of the thin plate 1, with the plastic positioning discs on the upper and lower surfaces of the thin plate 1 facing each other one-to-one.
[0029] The method for manufacturing the finished yarn stacking and positioning structure of this utility model involves purchasing common thin sheets (such as PVC plastic sheets, KT boards, or PVC boards) and cutting them into sheets of the same length and width according to the pallet size. Then, markings for the mounting screws are set according to the outer diameter of the finished yarn. Finally, pre-made plastic positioning discs are bolted to the marked positions on the thin sheets, thus completing the manufacturing process.
[0030] The advantages of this utility model's finished yarn stacking and positioning structure are: because it uses commonly used thin plates (such as PVC plastic plates, KT boards, or PVC boards), and plastic positioning plates can be installed on the thin plate matrix according to the finished yarns of different sizes, the cost and production cycle of mold making can be reduced, and the materials are readily available and low in cost.
[0031] The present invention relates to a finished yarn pallet packaging structure, comprising a pallet A0 and multiple layers of finished yarn A1 stacked sequentially on the pallet, and multiple layers of the aforementioned finished yarn stacking and positioning structure A2, wherein each finished yarn in each layer of finished yarn is fitted onto a plastic positioning disc 2.
[0032] To increase stability, a tightening strap A4 is tied between the thin plate 1 in the top layer of the finished yarn stacking and positioning structure and the lower surface of the upper plate A3 of the pallet.
[0033] The finished yarn stacking and positioning structure of this utility model achieves the advantages of low manufacturing cost and convenient manufacturing due to the adoption of the above-mentioned finished yarn stacking and positioning structure.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
