Description

Technical Field

[0001] This invention relates to the field of spinning technology, specifically to a technology for packaging and packing polyester staple fiber with cotton for large-capacity, fluffy spinning. Background Technology

[0002] In the spinning process, the polyester staple fiber bales used for cotton cleaning and packing are heavier and larger than other types of raw material bales. The dimensions of an unopened bale (length x width x height) are 110cm x 70cm x 90cm. After packing and opening, due to their large size, rigidity, and fluffiness, their volume changes significantly, especially the 90cm high bale, which expands to 130-140cm after opening, an increase of 50cm. The packing technique often involves vertically arranging two bales with a gap in the middle or three bales arranged vertically. This technique often leads to several problems: First, insufficient cotton supply to the cleaning and carding system, multiple empty compartments, affecting continuous cotton supply, causing intermittent downtime, and impacting output and quality. Second, individual bales may tip over during production, causing equipment malfunctions. This results in changes in the raw material composition ratio at different levels of the cotton bed, leading to composition fluctuations and changes in the blending composition ratio designed for spinning, affecting the consistency and stability of yarn quality, and causing serious quality problems such as yellow-white yarn and uneven defects on yarn segments.

[0003] To address this issue, a high-capacity, loose-spun polyester staple fiber packaging and cotton packing technology was designed to solve the aforementioned technical problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-capacity, fluffy polyester staple fiber packaging and cotton packing technology for spinning, which solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large-capacity, fluffy polyester staple fiber packaging technology for spinning, wherein during the packaging process of the cotton cleaning process, different batches of polyester staple fiber raw material packages with increased fluffiness after opening are stacked and packed in a specific cross-arrangement. The specific steps include: arranging different batches of raw material packages in a cross-arrangement along the longitudinal direction of the cotton box in a combination unit of two horizontal packages and one vertical package, until the entire box is stacked, and ensuring that the two horizontal packages are from different batches, and the vertical package and the adjacent horizontal package are from different batches.

[0006] Preferably, the raw material package is a polyester staple fiber cotton package after opening, with dimensions of 110cm in length, 70cm in width, and 90cm in height before opening, and the height expands to 130cm to 140cm after opening.

[0007] Preferably, the two horizontal packages refer to two raw material packages placed side by side and close together in the width direction of the cotton box.

[0008] Preferably, the vertical bundle refers to a raw material bundle placed adjacent to the two horizontal bundles along the length of the cotton box, with its long side aligning with the short side of the two horizontal bundles.

[0009] Preferably, the cross-arrangement creates a close contact and mutual support structure between the packages, which enhances the overall stability of the cotton box and effectively prevents the raw material packages from tilting or tipping over during production.

[0010] Preferably, the cross-arrangement method ensures that different batches of raw materials are staggered in both the longitudinal and transverse directions of the cotton box, thereby achieving uniformity and stability of the raw material composition ratio at different levels of the cotton platform.

[0011] Preferably, the process is applied to the cotton feeding process of the carding and combing system, aiming to ensure continuous and uniform cotton feeding and prevent multiple empty bins, intermittent machine stoppages, and yarn quality fluctuations caused by packing.

[0012] Preferably, the raw material packages inside the cotton box have a stable structure in which two horizontal packages and one vertical package are arranged sequentially in an alternating longitudinal direction. Beneficial effects

[0013] This invention provides a large-capacity, loose-fiber polyester staple fiber bales packing technology for cotton cleaning and packing. By employing a specific arrangement of two horizontally spaced bales and one vertically spaced bales in a staggered longitudinal pattern, this invention effectively enhances the overall structural stability of the loose-fiber polyester staple fiber bales within the cotton box, preventing the bales from tipping over during production. This technical solution ensures the continuity and stability of cotton supply to the cleaning and carding system, reducing downtime caused by supply interruptions. Simultaneously, by promoting a uniform, staggered spatial distribution of different batches of raw materials, it helps maintain the stability of the raw material composition ratio at each level of the cotton bed, thereby reducing yarn quality inconsistencies caused by fluctuations in blending ratios, such as yellowing or whitening of yarn and uneven defects. This has a positive effect on improving production efficiency and product quality. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-3 This invention provides a technical solution: a large-capacity, fluffy polyester staple fiber packaging technology for spinning. In the packaging process of the cotton cleaning process, different batches of polyester staple fiber raw material packages with increased fluffiness after opening are stacked and packed in a specific cross arrangement. The specific steps include: arranging the raw material packages of different batches in a cross arrangement along the longitudinal direction of the cotton box in a combination unit of two horizontal packages and one vertical package, until the entire box is stacked. During the stacking process, it is ensured that the two horizontal packages are from different batches, and the vertical package is from a different batch from the adjacent horizontal package.

[0019] In this embodiment, the raw material package is a polyester staple fiber cotton package after opening. Before opening, the package has dimensions of 110cm in length, 70cm in width, and 90cm in height. After opening, the height expands to 130cm to 140cm.

[0020] In this embodiment, the two horizontal packages refer to two raw material packages placed side by side and close together in the width direction of the cotton box.

[0021] In this embodiment, the "vertical one pack" refers to a raw material pack placed adjacent to the two horizontal packs along the length of the cotton box, with its long side direction matching the short side direction of the two horizontal packs.

[0022] In this embodiment, the tightly contacted and mutually supporting structure between the packages formed by the cross arrangement enhances the overall stability of the cotton box and effectively prevents the raw material packages from tilting or tipping over during production.

[0023] This embodiment is further configured such that, through the cross-arrangement method, the raw materials of different batches are staggered in both the longitudinal and transverse directions of the cotton box, thereby achieving uniformity and stability of the raw material composition ratio at different levels of the cotton platform.

[0024] In this embodiment, the process is further configured to be applied to the cotton supply process of the combing and cleaning system, in order to ensure continuous and uniform cotton supply and prevent multiple empty warehouses, intermittent machine stoppages and yarn quality fluctuations caused by packing.

[0025] In this embodiment, the raw material packages inside the cotton box are arranged in a stable structure with two horizontal packages and one vertical package arranged in a longitudinal sequence.

[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0027] Example: The raw material used is polyester staple fiber cotton bales, whose standard dimensions before opening are: length 110 cm, width 70 cm, and height 90 cm. After opening the bales using a bale opener or manually, due to the inherent fluffiness of the raw material, the height of the cotton bales expands significantly, increasing from the original 90 cm to between 130 cm and 140 cm, with a volume increase of approximately 50%. To ensure a continuous and stable cotton supply for subsequent cleaning and carding processes, and to ensure accurate blending ratios, multiple batches of polyester staple fiber bales after opening need to be placed into designated cotton boxes (or cotton warehouses).

[0028] In practice, operators use forklifts to perform the packing operation. First, at the starting end of the cotton box (e.g., the end near the cotton supply curtain), the first bale (e.g., batch A) and the second bale (e.g., batch B) are placed side-by-side tightly against each other along the transverse (width) direction of the cotton box, forming the first "transverse two-bale" unit. The two bales are positioned so that their length (110cm) is parallel to the longitudinal (length) direction of the cotton box, and their width (70cm) is parallel to the transverse (width) direction of the cotton box. The two bales are in close contact, providing lateral support to each other.

[0029] Next, a third bundle (e.g., batch C) is placed adjacent to the first "two horizontal bundles" unit along the longitudinal direction (i.e., length) of the cotton box. This third bundle is placed at a 90-degree angle to the aforementioned horizontal bundles; that is, its length (110cm) is parallel to the transverse direction of the cotton box, and its width (70cm) is parallel to the longitudinal direction, thus forming a "one vertical bundle." The front sidewall of this vertical bundle is in close contact with the rear sidewalls (or end faces) of the two horizontal bundles over a large area, forming effective longitudinal support and fit.

[0030] Then, repeat the above cross-arrangement pattern. On one side of the third package (batch C) (either behind or to the side when viewed longitudinally from the cotton box, depending on the cotton box layout), continue to place the fourth package (e.g., batch D) and the fifth package (e.g., batch E) side by side in the horizontal direction, forming a second "two-package horizontal" unit, ensuring that the two packages in this unit are from different batches than the previous vertical package (batch C). Next, behind this second horizontal unit, place another "one-package vertical," namely the sixth package (e.g., batch F), which crosses the horizontal unit and is also from a different batch than the adjacent horizontal packages. Thus, the "two-package horizontal (different batches) - one-package vertical (different batches)" arrangement is used as a basic unit, arranged sequentially, crosswise, and cyclically along the longitudinal direction of the cotton box until the entire preset loading space of the cotton box is filled. During the arrangement process, always ensure that adjacent, especially directly contacting, raw material packages come from different production batches.

[0031] Through the specific arrangement described in the above embodiments, the fluffy polyester staple fiber bales, after being opened, form a stable spatial structure within the cotton box that is mutually constrained and tightly supported. The two horizontally arranged bales rely on each other to prevent lateral tipping; while the vertically arranged bales, like wedges, support the horizontal bales longitudinally, effectively preventing them from tilting or tipping forward or backward under the force of equipment gripping or their own weight. The entire cotton box thus forms a highly stable raw material pile, fundamentally eliminating the possibility of individual bales or sections tipping over during production.

[0032] This robust structure ensures uniform and continuous gripping and feeding of the multi-compartment blending machine in the carding and combing system, preventing cotton supply interruptions, empty compartments, and subsequent equipment downtime caused by bale reversal. Simultaneously, because different batches of raw materials are forcibly and systematically staggered in the longitudinal and transverse directions of the cotton bin, each time unit the grabbing machine or feed roller picks up raw materials from different levels of the cotton table, automatically includes components from different batches mixed according to the designed proportions. This ensures the consistency of the raw material flow output from the cotton bin along the time axis, effectively preventing localized component homogenization caused by bale reversal. This completely eliminates major quality issues such as yellow-white yarn, uneven yarn drying, and increased defects caused by fluctuations in the blending ratio, significantly improving the quality stability and production efficiency of the final yarn product.
