Description

Technical Field

[0001] This application relates to the field of yarn frame technology, and in particular to a yarn frame for a double-layer weaving machine. Background Technology

[0002] The yarn trellis of a knitting machine is a core auxiliary device for knitting equipment. It is a component of various knitting machines such as circular knitting machines, flat knitting machines, and warp knitting machines. It is used to stably support yarn bobbins and continuously supply multiple yarns to the knitting machine, ensuring the continuity and stability of yarn delivery during the weaving process. However, most existing yarn trellises adopt a single-sided placement method, while knitting machines usually need to supply dozens to hundreds of yarns at the same time. This makes it impossible to achieve zoned operation and pre-place spare yarn bobbins. Yarn can only be loaded once, and the machine needs to be stopped during the yarn loading process, resulting in low production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer weaving machine yarn frame to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a double-layer weaving machine yarn frame, including a yarn frame body and an aisle frame. The aisle frame has several spaced-apart side aisle frames, and a placement area is formed between two adjacent sets of side aisle frames. The yarn frame body is installed in the placement area. Both the aisle frame and the side aisle frames are equipped with pedals for walking. A gate is provided on both sides of the yarn frame body. The yarn frame body includes several spaced-apart load-bearing frames. A cross frame is installed between two adjacent sets of load-bearing frames. Several spaced-apart yarn posts are installed on the cross frame. Several spaced-apart yarn bobbins are symmetrically arranged at both ends of the yarn posts. The yarn bobbins are used to place yarn cones. Two sets of symmetrically distributed side frames are also installed between two adjacent sets of load-bearing frames. The cross frame is located between the two sets of side frames.

[0006] The gantry includes two sets of spaced-apart support frames, with a support rod connecting the two sets of support frames. Several support rods are provided and spaced-apart along the length of the support frames. Several spaced-apart pulley components are provided on the side of the support frame facing the crossbeam. The pulley components include rollers, which abut against the side frame. The movement of the rollers on the side frame allows the gantry to move relative to the crossbeam along its length.

[0007] Two adjacent sets of support rods form openings through which the yarn packages pass, and the movement of the gantry makes the gantry and the yarn post parallel or intersecting with each other.

[0008] In one embodiment, when the gantry moves on the side frame via the cooperation of rollers, the yarn frame is in a placed state and a covered state.

[0009] When in the placement state, two adjacent sets of support rods are located on both sides of one set of yarn placing shafts, the yarn placing shafts are located in the center of the opening, and the yarn cones pass through the openings and are installed on the yarn placing shafts;

[0010] When in a covered state, the two adjacent sets of support rods are located outside one of the yarn-setting shafts, and the yarn through the opening is located outside the yarn-setting shaft.

[0011] In one embodiment, the pulley component includes two sets of spaced-apart bearing plates, one set of bearing plates is connected to a support and a side frame, and the roller component is rotatably disposed between the two sets of bearing plates.

[0012] An engagement area is formed between the two sets of bearing plates and roller components.

[0013] In one embodiment, a number of pins are provided on the side frame, and a limiting area is formed between two adjacent sets of pins.

[0014] In one embodiment, a wire guide plate is installed on one side of the support frame. Several wire guide plates are provided and distributed at intervals along the length of the support frame. Wire holes are evenly distributed on the wire guide plates.

[0015] In one embodiment, the side frame is provided with through holes, and several through holes are provided and distributed at intervals along the length direction of the side frame.

[0016] In one embodiment, the cable tray also has a side plate, which is hung on one side of the support frame when the cable tray is mounted on the support frame.

[0017] The cable guide plate has mounting holes for mounting bolts.

[0018] In one embodiment, a tension frame is also provided on the outside of the placement area, and two sets of tension wheels are installed on the tension frame at intervals.

[0019] The advantages or beneficial effects of the above technical solutions include at least the following:

[0020] This application discloses a yarn frame for a double-layer webbing machine. The main body of the yarn frame utilizes a multi-set interval support frame as its base, combined with a crossbeam and symmetrical side frames in a composite frame structure. Yarn posts for placing yarn bobbins are installed on the crossbeams, achieving high rigidity of the frame and preventing yarn tension fluctuations caused by yarn feeding sway. Because two sets of yarn-holding shafts are symmetrically distributed at both ends of the yarn posts, double the yarn capacity can be achieved within the same space, adapting to the dual-path warp yarn supply requirements of double-layer webbing. Furthermore, the gantry uses a frame structure of support frames and multiple sets of interval support rods. The frame structure, combined with multiple sets of pulley components with rollers facing the main frame, allows for quick switching between parallel and staggered states with the yarn bobbin by moving the gantry. This significantly reduces downtime for yarn changes. Furthermore, the staggered shielding structure between the gantry and the yarn bobbins provides protection against loosening of the yarn packages. The cooperation between the passageway frame and the side passageway frame enables operators to perform high-level yarn changes and safety inspections, solving the problem of low operational efficiency caused by existing yarn frames that can only perform single yarn loading operations.

[0042] Reference Figures 1-7 A double-layer weaving machine yarn frame includes a yarn frame body 1 and an aisle frame 6. The aisle frame 6 has several spaced-apart side aisle frames 61, and a placement area is formed between adjacent sets of side aisle frames 61. The yarn frame body 1 is installed in the placement area. Both the aisle frame 6 and the side aisle frames 61 are equipped with walking pedals. The aisle frame 6 and the spaced-apart side aisle frames 61 form a standardized placement area, in which the yarn frame body 1 is embedded. Together with the walking pedals, it forms a circular operating platform, solving the problem of climbing and operating high-position yarn beams. To address the challenges, a safe operating space is provided for yarn changing and inspection at all machine positions. The passageway frame 6 has movable barriers to prevent unauthorized access when yarn changing is not required. Both sides of the yarn frame body 1 are equipped with gate frames 2. The yarn frame body 1 includes several spaced-apart load-bearing frames 11. A crossbeam 12 is installed between adjacent sets of load-bearing frames 11. These spaced-apart load-bearing frames 11 serve as vertical load-bearing units, and the crossbeams 12 connect adjacent load-bearing frames 11 into a stable structure. The modular support frame 11 features a highly flexible, modular splicing structure. The number of support frames 11, crossbeams 12, and yarn posts 13 can be flexibly adjusted according to the number of warp yarns and production width of the webbing, adapting to the production needs of different specifications of double-layer webbing. Several spaced yarn posts 13 are installed on the crossbeam 12, and several spaced yarn guides 131 are symmetrically arranged at both ends of each yarn post 13. The yarn guides 131 are used to hold yarn cones. The yarn posts 13 adopt a design with symmetrically arranged yarn guides 131 on both sides, allowing a single yarn post 13 to... Simultaneously, multiple sets of yarn bobbins are hung to meet the supply demand of double warp yarns for double-layer webbing, improve space utilization, and adapt to the synchronous supply demand of warp yarns on both sides of double-layer webbing. Two sets of symmetrically distributed side frames 14 are also installed between the two adjacent sets of bearing frames 11. The cross frame 12 is located between the two sets of side frames 14. The side frames 14 are symmetrically arranged on both sides of the cross frame 12, which not only strengthens the overall structural rigidity of the yarn frame and improves the overall resistance to deformation of the yarn frame, but also avoids structural deformation after multiple yarn bobbins are fully loaded, and provides a guiding reference for the movement of the gantry 2.

[0043] The gantry 2 includes two sets of spaced-apart support frames 21, with support rods 22 connecting the two sets of support frames 21. Several support rods 22 are provided and spaced-apart along the length of the support frames 21. Several spaced-apart pulley components 3 are provided on the side of the support frame 21 facing the crossbeam 12. Each pulley component 3 has rollers 31, which abut against the side frame 14. The movement of the rollers 31 on the side frame 14 causes the gantry 2 to move relative to the crossbeam 12 along its length. A pulley component 3 is provided on the inner side of the support frame 21. The side frame 14 of the yarn frame body 1 is used as the moving track. The roller component 31 abuts against the side frame 14 to form a rolling friction pair, which converts the sliding friction between the gantry 2 and the yarn frame body 1 into rolling friction. This enables the gantry 2 to move smoothly and with low resistance and high precision along the length of the cross frame 12, adjusting the relative position of the gantry 2 and the yarn column 13. The rolling moving structure is easy to operate and has low translation resistance. Operators can complete the position adjustment of the gantry 2 with one hand, reducing the difficulty of operation.

[0044] Two adjacent sets of support rods 22 form openings for yarn packages to pass through. By moving the gantry 2, the gantry 2 and the yarn post 13 are made parallel or staggered to each other. The interval between the adjacent support rods 22 of the gantry 2 forms an operating opening for yarn packages to pass through. By translating the gantry 2, the two working states can be switched, realizing the rapid switching between yarn changing operation and production protection. When changing yarn, no structural parts need to be disassembled. Only the gantry 2 needs to be translated to expose all the yarn bobbins 131, which greatly shortens the downtime of yarn changing and improves the continuous operation efficiency of webbing production.

[0045] Based on the above structure, the main body 1 of the yarn frame serves as the core load-bearing base. Yarn columns 13, symmetrically arranged on both sides with yarn bobbins 131, ensure stable loading of double the number of yarn packages, providing ample warp yarn supply for the double-layer weaving machine. Simultaneously, the main body 1 of the yarn frame employs multiple sets of spaced-apart load-bearing frames 11 as vertical load-bearing units. Adjacent load-bearing frames 11 are rigidly connected by crossbeams 12, forming a modular, spliced ​​load-bearing system. This structural design not only gives the entire yarn frame structural rigidity, enabling it to bear the weight of multiple fully loaded yarn packages without deformation, but also allows for flexible adjustment of the number of warp yarns and weaving width required for double-layer weaving production, adapting to various needs. To meet different production requirements, the gantry 2 located on both sides of the yarn frame body 1 can be moved along the length of the yarn frame body 1. The movement of the gantry 2 enables flexible switching between two working states. When the gantry 2 is moved to be parallel and aligned with the yarn post 13, the interval opening of the support rod 22 of the gantry 2 corresponds to the position of the yarn placing shaft 131, which can quickly complete the installation and replacement of the yarn package. When the gantry 2 is moved to be intersecting with the yarn post 13, the gantry 2 forms physical protection for the yarn package, preventing the yarn package from loosening during high-speed yarn feeding. At the same time, it forms independent combing and limiting of the drawn yarn, ensuring stable tension during the yarn feeding process, preventing multiple yarn routes from tangling together, and ultimately achieving efficient, continuous and stable yarn supply for double-layer webbing production.

[0046] In one embodiment, reference is made to Figure 3 , Figure 4 and Figure 7 When the gantry 2 moves on the side frame 14 through the cooperation of the roller 31, the yarn frame is in a placement state and a blocking state. The relative position of the support rod 22 and the yarn shaft 131 is changed by the translation of the gantry 2, so as to realize the function switching. Furthermore, the two sets of gantry 2 can realize different states respectively, thereby realizing the flexibility of use.

[0047] When in the placement state, two adjacent sets of support rods 22 are located on both sides of one set of yarn placing shafts 131. The yarn placing shaft 131 is located in the center of the opening. The yarn package passes through the opening and is installed on the yarn placing shaft 131. In the placement state, the opening of the support rod 22 is completely aligned with the yarn placing shaft 131, forming an unobstructed straight-through yarn feeding channel. The yarn package can be directly installed on the yarn placing shaft 131 through the opening.

[0048] When in the shielded state, the two adjacent sets of support rods 22 are located outside one of the yarn placing shafts 131, and the yarn bobbin passes through the opening outside the yarn placing shaft 131. In the shielded state, the support rods 22 move to the axial outside of the yarn placing shaft 131 to form a physical protection structure, blocking the axial exit path of the yarn bobbin, while not interfering with the normal radial unwinding of the yarn. The above structure does not require additional locking, buckle or other fixing parts. The state switching can be completed by simply moving the gantry 2, which is a one-step process and reduces the complexity of the operator's actions.

[0049] In one embodiment, reference is made to Figure 3 and Figure 6 The pulley component 3 includes two sets of spaced-apart bearing plates 32. One set of bearing plates 32 is connected to a support part 321 and to the side frame 14. The roller component 31 is rotatably disposed between the two sets of bearing plates 32. An engagement area is formed between the two sets of bearing plates 32 and the roller component 31. When the pulley component 3 is connected to the side frame 14, part of the side frame 14 is embedded in the engagement area. The structure of the roller component 31 clamped by the double bearing plates 32 is adopted. The side frame 14 is used as the rolling track. The rolling surface of the roller component 31 directly abuts against the surface of the side frame 14 to achieve smooth translation of the gantry 2. The rolling guidance and anti-detachment limit are combined into one, without the need to install an additional independent guide rail. The existing side frame 14 is directly used as the track, which reduces manufacturing costs and structural complexity. At the same time, the double bearing plates 32 form a limit from both sides of the side frame 14, restricting the displacement of the gantry 2 in the direction perpendicular to the side frame 14, preventing the gantry 2 from deflecting or tipping over, and improving the stability of operation.

[0050] In one embodiment, reference is made to Figures 3-5 The side frame 14 is equipped with several pins 4. A limiting area is formed between two adjacent sets of pins 4. When several pulley components 3 are located in the limiting area, the pulley components 3 move relative to each other within the limiting area. The pins 4 form physical limiting points on the side frame 14, which rigidly limit the movement stroke of the pulley components 3, i.e., the translation range of the gantry 2. This prevents the gantry 2 from moving too much, causing the protection to fail or detach from the side frame 14. By limiting the movement stroke of the gantry 2, the position of the gantry 2 in the placement and shielding states is ensured to be accurate, avoiding problems such as inconvenience in yarn loading or protection failure caused by incomplete movement.

[0051] In one embodiment, reference is made to Figure 3 , Figure 4 and Figure 8 A guide plate 5 is installed on one side of the support frame 11. Several guide plates 5 are provided and distributed at intervals along the length of the support frame 11. Thread holes 51 are evenly distributed on the guide plates 5. The guide plates 5 serve as a yarn separation and guiding structure. Each yarn unwound from the bobbin passes through the corresponding thread hole 51, achieving independent isolation of a single yarn, sorting the yarn path, preventing multiple yarns from tangling together during high-speed unwinding, unifying the yarn feeding angle and stroke of each yarn, improving the weaving yield, and the spaced guide plates 5 can be arranged according to the number of yarn layers and quantities to adapt to the production of double-layer webbing of different specifications.

[0052] The guide plate 5 also has a side plate 52. When the guide plate 5 is installed on the support frame 11, the side plate 52 is hung on one side of the support frame 11. Through the cooperation of the side plate 52, the guide plate 5 can move relative to the support frame 11 along its length. The tool-free sliding adjustment of the guide plate 5 is achieved by the hook-on side plate 52. The spacing and position of the guide plate 5 can be flexibly changed according to the warp density and number of warp yarns. After adjustment, it is locked with bolts to ensure that the position is stable in the working state and will not shift due to yarn pulling. This adapts to the production of double-layer webbing of different specifications and reduces equipment modification costs.

[0053] The guide plate 5 has mounting holes for mounting bolts. The bolt locking method ensures that the guide plate 5 is stable in position during high-speed weaving and will not shift, thus continuously ensuring the yarn guiding effect and maintaining uniform and stable yarn feeding tension.

[0054] In one embodiment, reference is made to Figure 3 , Figure 4 and Figure 6 The side frame 14 is provided with several through holes 141, which are spaced apart along the length of the side frame 14. When the pin 4 is installed on different through holes 141, the limiting area is expanded or reduced. The standardized through hole 141 is used as the installation position of the pin 4. By changing the installation position of the pin 4, the size of the limiting area can be flexibly adjusted, thereby changing the movable stroke of the gantry 2 to adapt to different specifications of yarn bobbins and yarn placing shafts 131. This allows for flexible adjustment of the moving stroke of the gantry 2. For example, when a large diameter yarn bobbin requires a larger yarn opening, the limiting area can be expanded to allow the gantry 2 to move a greater distance, adapting to different sizes of yarn bobbins and different lengths of yarn placing shafts 131, thereby improving the error tolerance of the operation.

[0055] In one embodiment, reference is made to Figure 1 and Figure 2 A tension frame 7 is also installed on the outside of the placement area. Two sets of tension wheels 71 are installed on the tension frame 7. The two sets of tension wheels 71 form a standardized yarn path, which can perform secondary guidance and correction on the yarn after splitting, unify the entry angle and conveying stroke of all yarns into the loom, and avoid the problem of asynchronous yarn feeding in two paths due to yarn deviation and different strokes.
