Description

Technical Field

[0001] This invention belongs to the field of cotton textile technology, specifically referring to a yarn conveyor for cotton textiles. Background Technology

[0002] Core-spun yarn is a type of composite yarn used in cotton textiles. It typically uses strong and tough synthetic filaments (such as polyester or nylon) as the core yarn, with cotton fibers spirally wrapped around it. Its structure combines the advantages of both: the core yarn provides high strength, wrinkle resistance, and dimensional stability, while the outer cotton layer gives the fabric a natural sense of comfort, such as moisture absorption, breathability, softness, and skin-friendliness, as well as good dyeing properties. This process allows the fabric to possess both the durability of synthetic fibers and the comfort of cotton, improving the elasticity and shape retention of the finished product while preserving the appearance and feel of cotton, thus achieving an optimized combination of function and comfort.

[0003] In the production of core-spun yarn, the core yarn and the outer yarn need to be fed in and compounded at the same time. In order to achieve more yarn compounding within the limited space of the yarn rack, the yarn bobbins are usually arranged in an extremely compact and dense manner. Although this high-density layout effectively improves space utilization and production efficiency, it also increases the difficulty of operation. When the yarn on the yarn bobbin is used up and needs to be replaced, the narrow interval between adjacent yarn bobbins will seriously hinder the operator's replacement action, increasing the difficulty and time of bobbin replacement. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a yarn conveyor for cotton spinning, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: A yarn conveyor for cotton spinning is proposed, comprising: Positioning frames, multiple of which are arranged in a linear pattern, each positioning frame includes a vertical pole and a horizontal pole vertically fixed to the vertical pole; Two sets of conveyor frames are fixed to the vertical and horizontal poles, respectively. Two sets of yarn bobbin support frames are installed on the conveyor frame and are respectively connected to the first yarn bobbin and the second yarn bobbin; A guide frame is mounted on the horizontal bar and is used to guide the yarns of the first and second yarn spools. The yarn bobbin support frame includes a bobbin frame and a bobbin shaft connecting cylinder. The bobbin frame is fixedly provided with bobbin shaft connecting cylinders corresponding to the number of the first or second yarn bobbins. The bobbin frame is configured to slide along the conveyor frame and slide in / out from both ends of the conveyor frame for replacing the first or second yarn bobbins on the entire bobbin frame. The bobbin shaft connecting cylinder is configured to hold a single first or second yarn bobbin.

[0006] Furthermore, both the first yarn bobbin and the second yarn bobbin are provided with a bobbin shaft at their center positions. A bobbin head is fixedly provided at the end of the bobbin shaft. A limiting engagement member is provided on the bobbin shaft connecting tube to engage with the bobbin head. The bobbin shaft and the bobbin shaft connecting tube are engaged with each other through the bobbin head and the limiting engagement member.

[0007] Furthermore, the limiting engagement member includes a plurality of centrally symmetrical elastic latches. The limiting engagement member moves axially within the spool shaft connecting cylinder, including a first position and a second position. When the limiting engagement member is in the first position, the plurality of elastic latches are located inside the spool shaft connecting cylinder, the elastic latches abut against each other along the axis, and can lock the spool shaft head at the end of the spool shaft, thus fixing the spool shaft to the spool shaft connecting cylinder. When the limiting engagement member is in the second position, a portion of the plurality of elastic latches are located outside the spool shaft connecting cylinder, the elastic latches move away from each other along the axis, allowing the spool shaft head to disengage from the plurality of elastic latches.

[0008] Furthermore, the elastic flaps are configured to be four in number, and the middle area of ​​each elastic flap is provided with a groove that mates with the spool head.

[0009] Furthermore, the inner wall of the spool connecting cylinder is provided with a limiting groove, which is configured in an "L" shape. The limiting groove includes a first sliding groove parallel to the axis and disposed on the inner wall of the spool connecting cylinder, and a second sliding groove disposed circumferentially on the inner wall of the spool connecting cylinder. The outer wall of the limiting engagement member is provided with a protruding protrusion that can slide inside the limiting groove. When the protrusion is in the first sliding groove, the limiting engagement member can move between the first position and the second position. When the protrusion is in the first sliding groove, the limiting engagement member is limited to the first position.

[0010] Furthermore, a dust cover is fixedly provided on the outer periphery of the yarn bobbin connecting cylinder, and the diameter of the dust cover is greater than or equal to the diameter of the second yarn bobbin.

[0011] Furthermore, the conveying frame includes a first conveying frame and a second conveying frame. The first conveying frame is fixed to the side wall of the vertical rod, and the second conveying frame is fixed to the bottom of the horizontal rod. The axis of the first yarn bobbin is horizontally mounted on the first conveying frame through the yarn bobbin support frame, and the axis of the second yarn bobbin is vertically mounted on the second conveying frame through the yarn bobbin support frame. The number of the first or second conveying frames corresponds to the number of the first or second yarn bobbins.

[0012] Furthermore, the spool rack extends into the first or second conveyor frame and is equipped with a connecting pulley. The connecting pulley is configured to slide within the first or second conveyor frame, and is equipped with a self-locking mechanism to fix the connecting pulley in a set position within the first or second conveyor frame.

[0013] Furthermore, the conductor frame includes a connecting rod, a first conductor rod group, and a second conductor rod group. The connecting rod is vertically fixed to the horizontal rod. The first conductor rod group and the second conductor rod group are arranged parallel to each other on the connecting rod. The first conductor rod group is located on the upper side of the horizontal rod, and the second conductor rod group is located on the lower side of the horizontal rod. Both the first conductor rod group and the second conductor rod group are arranged horizontally.

[0014] Furthermore, the number of the first guide rod group and the second guide rod group is the same as the number of the first yarn bobbin or the second yarn bobbin. Each first yarn bobbin or the second yarn bobbin introduces yarn into the corresponding first guide rod group or the second guide rod group. The first guide rod group and the second guide rod group are provided with a groove corresponding to the number of the first yarn bobbin or the second yarn bobbin.

[0015] Beneficial effects: This invention solves the problem of difficult replacement caused by the dense arrangement of yarn bobbins in core-spun yarn production by using a sliding yarn bobbin support frame and a modular bobbin shaft connection structure. The bobbin support frame can slide in or out from both ends of the conveyor frame as a whole, realizing rapid batch replacement of yarn bobbins, reducing the replacement time and labor intensity of operators in confined spaces. The matching design of the limiting clamp and L-shaped limiting groove makes the installation and disassembly of yarn bobbins more convenient and reliable, and allows for targeted replacement of individual yarn bobbins, simplifying the operation steps. The layered guide wire frame structure realizes the orderly guidance of yarn and improves the stability of yarn conveying. Attached Figure Description

[0019] The technical solutions in 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a yarn conveying frame for cotton textiles, including a positioning frame 10, a conveying frame 20, a yarn bobbin support frame 30, and a wire guide frame 40.

[0022] The positioning frames 10 are arranged linearly along the production line. Each positioning frame 10 is vertically fixed by a vertical rod 11 and a horizontal rod 12 to form a stable support frame. Two sets of conveyor frames 20 are respectively installed on the side of the vertical rod 11 and the bottom of the horizontal rod 12 to support the yarn bobbin support frame 30. The yarn bobbin support frame 30 is equipped with a first yarn bobbin 01 and a second yarn bobbin 02, which correspond to the placement of the core yarn and the outer yarn, respectively. The guide wire frame 40 is fixed on the horizontal rod 12 to guide the yarn drawn from the yarn bobbin in an orderly manner to the subsequent textile equipment. The overall structure is compact and supports the synchronous conveying of multiple sets of yarns. It is suitable for the production of composite yarns such as core-spun yarn.

[0023] Furthermore, the yarn bobbin support frame 30 includes a bobbin frame 31 and a bobbin shaft connecting cylinder 32. The bobbin frame 31 is fixedly equipped with bobbin shaft connecting cylinders 32 corresponding to the number of first yarn bobbins 01 or second yarn bobbins 02. The bobbin frame 31 is configured to slide along the conveyor frame 20 and slide in / out from both ends of the conveyor frame 20 for replacing the first yarn bobbins 01 or second yarn bobbins 02 on the entire bobbin frame 31. The bobbin shaft connecting cylinder 32 is configured to hold a single first yarn bobbin 01 or second yarn bobbin 02. The bobbin frame 31 is embedded in the track of the conveyor frame 20 through the connecting rod pulley 311 at its bottom and can slide along the track. When the yarn in a row of yarn bobbins is used up, the operator can slide the entire bobbin frame 31 out from one end of the conveyor frame 20 to replace the entire row of yarn bobbins in a spacious external area. After replacement, it can slide back into the conveyor frame 20 and be fixed, which can reduce the difficulty of replacing individual bobbins in densely packed arrangements.

[0024] Furthermore, both the first yarn bobbin 01 and the second yarn bobbin 02 are equipped with a bobbin shaft 03 at their center. A bobbin head 031 is fixedly provided at the end of the bobbin shaft 03. A limiting engagement piece 321 is provided on the bobbin shaft connecting cylinder 32 to engage with the bobbin head 031. The bobbin shaft 03 and the bobbin shaft connecting cylinder 32 are engaged by the bobbin head 031 and the limiting engagement piece 321. During installation, the bobbin head 031 is inserted into the limiting engagement piece 321, and the engagement structure achieves quick fixation. During disassembly, the bobbin head 031 can be released by pushing or rotating the limiting engagement piece 321, and the yarn bobbin can be removed. This connection method does not require tools, is easy to operate, and provides a stable connection.

[0025] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the limiting engagement member 321 includes a plurality of centrally symmetrical elastic flaps. The limiting engagement member 321 moves axially within the spool shaft connecting cylinder 32, including a first position and a second position. When the limiting engagement member 321 is in the first position, the plurality of elastic flaps are located inside the spool shaft connecting cylinder 32, and the elastic flaps abut against each other along the axis, thus locking the spool shaft head 031 at the end of the spool shaft 03, fixing the spool shaft 03 to the spool shaft connecting cylinder 32. When the limiting engagement member 321 is in the second position, the plurality of elastic flaps are partially located... On the outside of the yarn bobbin connecting cylinder 32, the elastic locking flaps move away from each other along the axis, allowing the yarn bobbin head 031 to disengage from the multiple elastic locking flaps. The limiting locking component 321 is composed of multiple elastic locking flaps, which are symmetrically arranged and have a certain radial elasticity. When the limiting locking component 321 is in the first position (installation position), the locking flaps retract inward and tightly lock the yarn bobbin head 031. When pushed to the second position (release position), the locking flaps expand outward, and the head can be easily disengaged. This structure achieves locking and releasing through axial movement and is suitable for production scenarios where yarn bobbins are frequently changed.

[0026] Specifically, there are four elastic clips, and the middle area of ​​the elastic clips is provided with a groove that cooperates with the yarn bobbin head 031. Each clip has an arc-shaped groove on its inner side, which matches the shape of the yarn bobbin head 031, increasing the contact area and clamping force, and preventing the yarn bobbin from shaking or falling off during rotation.

[0027] like Figure 6 As shown, the inner wall of the spool connecting cylinder 32 is provided with a limiting groove 320, which is configured in an "L" shape. The limiting groove 320 includes a first sliding groove parallel to the axis and disposed on the inner wall of the spool connecting cylinder 32, and a second sliding groove disposed circumferentially on the inner wall of the spool connecting cylinder 32. The outer wall of the limiting engagement member 321 is provided with a protruding protrusion that can slide inside the limiting groove 320. When the protrusion is in the first sliding groove, the limiting engagement member 321 can move between a first position and a second position. When the protrusion is in the second slide groove, the limiting engagement member 321 is limited to the first position. The inner wall of the bobbin shaft connecting cylinder 32 is provided with an L-shaped limiting groove 320, including an axial first slide groove and a circumferential second slide groove. The protrusion on the outer wall of the limiting engagement member 321 can move axially along the first slide groove to realize the push and pull of the engagement member. When the protrusion slides into the second slide groove and rotates a certain angle, the limiting engagement member 321 is locked in the first position to prevent accidental loosening due to vibration during yarn conveying and improve the safety of use.

[0028] In some embodiments, a dust cover 322 is fixedly provided on the outer periphery of the yarn bobbin connecting cylinder 32. The diameter of the dust cover 322 is greater than or equal to the diameter of the second yarn bobbin 02. The dust cover 322 can cover the upper part of the yarn bobbin, effectively preventing fly hair and dust in the workshop from falling onto the yarn surface, keeping the yarn clean, and reducing yarn breakage and quality problems.

[0029] like Figure 2 and Figure 3 As shown, the conveyor frame 20 includes a first conveyor frame 21 and a second conveyor frame 22. The first conveyor frame 21 is fixed to the side wall of the vertical rod 11, and the second conveyor frame 22 is fixed to the bottom of the horizontal rod 12. The axis of the first yarn bobbin 01 is horizontally mounted on the first conveyor frame 21 through the yarn bobbin support frame 30, and the axis of the second yarn bobbin 02 is vertically mounted on the second conveyor frame 22 through the yarn bobbin support frame 30. The number of the first conveyor frame 21 or the second conveyor frame 22 corresponds to the number of the first yarn bobbin 01 or the second yarn bobbin 02. The first yarn bobbin 01 is placed horizontally, and the second yarn bobbin 02 is placed vertically. This layout makes full use of the three-dimensional space, so that more yarn bobbins can be accommodated on the same positioning frame 10, which can meet the needs of high-density production.

[0030] The yarn bobbin rack 31 extends into the first conveyor rack 21 or the second conveyor rack 22 and is equipped with a connecting rod pulley 311. The connecting rod pulley 311 is configured to slide within the first conveyor rack 21 or the second conveyor rack 22, and is equipped with a self-locking mechanism to fix the connecting rod pulley 311 in a set position within the first conveyor rack 21 or the second conveyor rack 22. The pulley is equipped with a self-locking mechanism (such as a spring pin, friction brake pad, etc.) which can automatically lock after sliding to the designated position to prevent the rack from shifting under yarn tension or equipment vibration, and to ensure the stability of the yarn lead-out position.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the conductor frame 40 includes a connecting rod 41, a first conductor rod group 42, and a second conductor rod group 43. The connecting rod 41 is vertically fixed to the horizontal rod 12. The first conductor rod group 42 and the second conductor rod group 43 are arranged parallel to each other on the connecting rod 41, with the first conductor rod group 42 located on the upper side of the horizontal rod 12 and the second conductor rod group 43 located on the lower side of the horizontal rod 12. Both the first conductor rod group 42 and the second conductor rod group 43 are arranged horizontally. The conductor frame 40 is fixed to the horizontal rod 12 by the connecting rod 41. The first conductor rod group 42 and the second conductor rod group 43 are arranged vertically parallel to each other. The upper group guides the yarn from the first yarn bobbin 01, and the lower group guides the yarn from the second yarn bobbin 02, realizing layered guidance of the yarn and avoiding mutual tangling. The conductor rods have grooves corresponding to the number of yarn bobbins. Each yarn passes through the corresponding groove independently, ensuring that the yarn is arranged in an orderly manner and the tension is uniform.

[0032] Furthermore, the number of the first guide rod group 42 and the second guide rod group 43 is consistent with the number of the first yarn bobbin 01 or the second yarn bobbin 02. Each first yarn bobbin 01 or second yarn bobbin 02 guides the yarn into the corresponding first guide rod group 42 or second guide rod group 43. The first guide rod group 42 and the second guide rod group 43 are provided with grooves corresponding to the number of first yarn bobbins 01 or second yarn bobbins 02. After the yarn from each yarn bobbin is led out, it enters the independent groove on the guide rod group. The surface of the groove is smooth, reducing yarn friction damage. This structure not only guides the yarn direction, but also preliminarily adjusts the yarn tension, providing stable yarn input conditions for subsequent composite processes.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
