Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a positioning mechanism for a warp knitting machine. Background Art

[0002] A knitted fabric is formed by simultaneously looping one or several groups of yarns arranged in parallel on all the working needles of the warp feeding machine. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine. A warp knitting machine is generally composed of a warp knitting main machine, a pulling component and a reduction motor, and multiple fixing mechanisms need to be deployed during use.

[0003] During the operation of the warp knitting machine, the warp threads are usually wound around the disc heads to achieve orderly supply and weaving. As the bearing component of the warp threads, the stable rotation of the disc heads is crucial to the smooth supply of the warp threads and the quality of the fabric. When there is no effective limit mechanism, the two disc heads are prone to move towards each other during high-speed rotation. This may be caused by a variety of reasons, such as vibration during machine operation, uneven tension, manufacturing and installation errors, etc.

[0004] Once the high-speed rotating warps move towards each other and cause position deviation, a series of serious problems will occur. First, the winding of the warp will become irregular, and may overlap, cross or loosen, which directly affects the tension distribution of the warp during the weaving process, resulting in uneven density of the fabric, defects and quality defects.

[0005] Secondly, position deviation may lead to increased wear of the warp, reduce the service life of the warp and increase production costs. In addition, irregular warp winding may also lead to warp breakage, interrupting production, reducing production efficiency, and increasing the time and cost of maintenance and readjustment.

[0006] In summary, in order to ensure the normal operation of the warp knitting machine, improve fabric quality and production efficiency, it is very necessary to design an effective positioning mechanism to limit the relative movement of the warp heads and ensure their stable and accurate rotation.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-3 In an embodiment of the utility model, a positioning mechanism for a warp knitting machine includes a head frame 1, a fixing bone 2 is extended on the outer side of the head frame 1, a first supporting rod 3 and a second supporting rod 4 are sequentially penetrated along the side ends of the fixing bone 2, and the first supporting rod 3 and the second supporting rod 4 are respectively arranged in half on both sides of the fixing bone 2, and the first supporting rod 3 and the second supporting rod 4 are arranged at intervals and pass through the fixing bone 2 to form two separated first assembly positions 5;

[0032] A first stopper 6 corresponding to the inner side of the first assembly position 5 is extended along the upper end surface of the fixing bone 2, a fixing plate 7 is extended along the lower end surface of the fixing bone 2 or the pan head frame 1, and second stoppers 8 corresponding to the outer side of the first assembly position 5 are respectively extended on the outer sides of both ends of the fixing plate 7;

[0033] The first assembly position 5 is provided with a first disk head 9 and a second disk head 10 movably arranged in sequence from the inside to the outside, and the second supporting rod 4 is provided with a limiting component 11 between the first disk head 9 and the second disk head 10, and the two ends of the limiting component 11 are respectively provided with a first roller 12 abutting against the first disk head 9 and a second roller 13 abutting against the second disk head 10.

[0034] In the technical solution of the utility model, the pan head frame 1 serves as the basic supporting structure of the entire mechanism, ensuring the overall stability, and the fixing bone 2 extends from the outside of the pan head frame 1, providing a firm installation position for the subsequent first supporting rod 3, the second supporting rod 4, the first limiting member 6, the second limiting member 8 and the limiting assembly 11;

[0035] The first supporting rod 3 and the second supporting rod 4 sequentially pass through the side ends of the fixed bone 2, and are respectively arranged in half on both sides thereof. This spacing arrangement not only reasonably divides the two separated first assembly positions 5, but also enables each first assembly position 5 to be evenly supported; when the first pan head 9 and the second pan head 10 are respectively installed on the first assembly positions 5, the first supporting rod 3 and the second supporting rod 4 can effectively bear the weight of the first pan head 9 and the second pan head 10, and provide stable support during the rotation process, thereby reducing the shaking caused by the shift of the center of gravity or imbalance;

[0036] The first limiting member 6 located on the upper end surface of the fixing bone 2 limits the first pan head 9 in the horizontal direction from the inside, while the fixing plate 7 located on the lower end surface of the fixing bone 2 or the pan head frame 1 and the second limiting members 8 on the outer sides of the two ends thereof constrain the second pan head 10 in the horizontal direction from the outside. This left-right horizontal matching limiting mode can effectively prevent the first pan head 9 and the second pan head 10 from excessively moving in the horizontal direction, and can control the horizontal displacement of the first pan head 9 and the second pan head 10 within a very small range regardless of the change in warp tension or the vibration of the machine.

[0037] The limiting assembly 11 arranged between the second supporting rod 4 and the first pan head 9 and the second pan head 10 is a key design for the problem of the pan heads moving toward each other. When the first pan head 9 and the second pan head 10 tend to move toward each other during high-speed rotation, the first roller 12 and the second roller 13 at both ends of the limiting assembly 11 contact with the corresponding pan heads and generate resistance. Due to the rolling characteristics of the rollers, the rollers can reduce the hard friction between the pan heads and the pan heads while preventing the movement toward each other, and can also adapt to the slight position adjustment of the pan heads during normal rotation.

[0038] In summary, through the stable disc head frame 1, the fixed bone 2 and the reasonably distributed first supporting rod 3 and the second supporting rod 4, a solid and balanced supporting foundation is provided for the disc head when it rotates at high speed, which greatly reduces the shaking and instability caused by vibration or imbalance, and ensures the stability of the warp knitting machine; the left and right horizontal cooperation of the first limiter 6 and the second limiter 8 provides a strong constraint on the disc head in the horizontal direction, significantly reduces the warp tension fluctuation and uneven winding caused by horizontal shaking, and ensures the quality consistency of the fabric in the width direction; through this horizontal limiting method, the spacing between the two disc heads can be accurately controlled to avoid warp crossing, entanglement or excessive stretching caused by spacing changes, thereby improving the service life of the warp and the weaving accuracy of the fabric, and combined with the roller design in the limiting component 11, while providing effective limiting, it also allows the disc head to be fine-tuned within the normal working range to adapt to different weaving speeds, warp tension changes and working conditions, thereby enhancing the flexibility and adaptability of the entire positioning mechanism.

[0039] In the embodiment of the utility model, the second supporting rod 4 includes a first end 14 corresponding to the first disc head 9 and a second end 15 corresponding to the second disc head 10 , and the junction of the first end 14 and the second end 15 forms a second assembly position 16 that cooperates with the limiting component 11 .

[0040] The first supporting rod 3 and the second supporting rod 4 pass through the side ends of the fixed bone 2 in an orderly manner and are distributed in half on both sides to form two clear assembly positions, thereby providing balanced and stable support for the pan head and effectively counteracting the centrifugal force and vibration generated by the high-speed rotation of the pan head;

[0041] In the unique design of the second supporting rod 4, the first end 14 corresponding to the first disc head 9 and the second end 15 corresponding to the second disc head 10 form a second assembly position 16 for matching the limiting component 11 at the intersection. This design enables the limiting component 11 to be accurately and firmly installed on the second supporting rod 4. When the first disc head 9 and the second disc head 10 tend to move towards each other, the limiting component 11 can play a blocking role in a timely and effective manner.

[0042] In the embodiment of the utility model, the limiting assembly 11 includes a first connecting member 17, a second connecting member 18, a bolt pair 19, and the first roller 12 and the second roller 13 rotatably connected to the first connecting member 17. The first connecting member 17 and the second connecting member 18 are butt-matched at the assembly position, and a connecting hole 20 is opened at the assembly position to match the bolt pair 19.

[0043] The limit assembly 11 itself is composed of a first connecting member 17, a second connecting member 18, a bolt pair 19, and a rotatable first roller 12 and a second roller 13. The first connecting member 17 and the second connecting member 18 are butt-matched at the assembly position, and are fastened together by the bolt pair 19 passing through the connecting hole 20 at the assembly position. This design enables the limit assembly 11 to be tightly mounted on the second supporting rod 4, and when the first disk head 9 and the second disk head 10 tend to move toward each other, effective blocking and restriction are provided by the rotatable first roller 12 and the second roller 13. At the same time, the limit assembly 11 is connected by the bolt pair 19, so that when the components are worn or fail, they can be easily disassembled and replaced, reducing maintenance costs and downtime.

[0044] In the embodiment of the utility model, the second assembly position 16 includes an upper groove 21 and a lower groove 22 located on the second supporting rod 4, the lower end of the first connecting member 17 is protrudingly provided with a first docking block 23 that docks with the upper groove 21, and the upper end of the second connecting member 18 is protrudingly provided with a second docking block 24 that docks with the lower groove 22, wherein the connecting hole 20 is opened in the upper groove 21 and the lower groove 22.

[0045] The limiting assembly 11 is composed of a first connecting member 17, a second connecting member 18, a bolt pair 19, and a rotatable first roller 12 and a second roller 13. The first docking block 23 at the lower end of the first connecting member 17 is docked with the upper groove 21, and the second docking block 24 at the upper end of the second connecting member 18 is docked with the lower groove 22. The bolt pair 19 is fastened through the connecting holes 20 in the upper groove 21 and the lower groove 22. This design enables the various components to be precisely matched to form a tight and stable overall structure. The cooperation between the upper groove 21 and the lower groove 22 and the corresponding docking blocks provides a clear installation position and guide for the limiting assembly 11, ensuring that it can play its role accurately during work and effectively limit the relative movement of the first disk head 9 and the second disk head 10.

[0046] In the embodiment of the utility model, a connecting structure is provided between the upper groove 21 and the first docking block 23 , and between the lower groove 22 and the second docking block 24 .

[0047] A connection structure is provided between the upper groove 21 and the first docking block 23 and between the lower groove 22 and the second docking block 24, mainly to enhance the connection stability and reliability between the first connecting member 17 and the upper groove 21, and between the second connecting member 18 and the lower groove 22. This connection structure can provide additional fixation and positioning to prevent the first connecting member 17 and the second connecting member 18 from loosening, displacement or separation during operation. It helps to better transmit and disperse the force and stress generated during operation, ensure that the entire limit assembly 11 can function stably, and effectively limit the relative movement of the first pan head 9 and the second pan head 10;

[0048] Among them, the connection structure can be a bayonet connection: a bayonet structure that cooperates with each other is set on the upper groove 21 / lower groove 22 and the first docking block 23 / second docking block 24, and fixation is achieved by the engagement of the bayonet; it can also be a key connection: similar to the cooperation between the key and the keyway, a key and a keyway are set on the upper groove 21 / lower groove 22 and the first docking block 23 / second docking block 24 to transmit torque and prevent relative rotation. It can also be other connection methods, which will not be elaborated one by one here.

[0049] In the embodiment of the utility model, the first limiting member 6 is in an inverted U-shape, and two sides of the first limiting member 6 are respectively matched with the first pan heads 9 located inside the two first assembly positions 5.

[0050] Through this design, the first limiting member 6 can simultaneously perform limiting cooperation with the first disc heads 9 located inside the two first assembly positions 5 .

[0051] In the embodiment of the utility model, the second limiting member 8 is L-shaped, and the vertical end of the second limiting member 8 is limitedly matched with the second pan head 10 located outside the first assembly position 5 .

[0052] Through this design, the vertical end of the second limiting member 8 can be effectively limited and matched with the second pan head 10 located outside the first assembly position 5;

[0053] The second limiting member 8 is combined with the first limiting member 6 to limit the pan head from both the inner and outer sides, further enhancing the stability of the pan head in the horizontal direction and reducing the shaking and deviation of the pan head during operation.

[0054] In the embodiment of the utility model, the first limiting member 6 and the second limiting member 8 are both sleeved with rollers.

[0055] The design of sleeve-mounting rollers on the first limiting member 6 and the second limiting member 8 is mainly to reduce the friction resistance between the disc head and the disc head while realizing the limiting function.

[0056] In the embodiment of the utility model, the pan head frame 1 is annular, and a plurality of the fixing bones 2 are provided, and the plurality of fixing bones 2 are arranged in an annular array along the pan head frame 1 .

[0057] The annular pan head frame 1 can better adapt to the circular motion of the pan head and provide uniform support force distribution, while multiple fixing bones 2 are arranged in a circular array, making the support and limitation of the pan head more balanced and stable. This layout can effectively disperse the various forces generated by the pan head when it rotates at high speed, ensuring that the entire structure can withstand large loads and dynamic changes; at the same time, the design of this annular array facilitates the installation of multiple pan heads on the same pan head frame 1, realizing large-scale production layout and improving production efficiency.

[0058] Preferably, a limiting assembly 11 may also be provided at a position corresponding to the first supporting rod 3 .
