Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and in particular, to a double needle bed warp knitting machine. Background Art

[0002] A double needle bed warp knitting machine includes a loop forming device, a comb device, and a transmission device. The loop forming device includes symmetric front and rear loop shedding parts, symmetric front and rear needle bed parts, and symmetric front and rear sinker parts. Among them, latch needles are used in the front and rear needle bed parts. Through the warp knitting machine, one or several groups of parallel arranged yarns can be knitted into knitted fabrics. Through the latch needles, a large yarn laying area can be achieved, and fancy fabrics can be knitted.

[0003] In the patent document with the publication number: CN219157134U, a double needle bed warp knitting machine for knitting terry velvet fabric is disclosed, which includes a frame, a front needle bed, a rear needle bed, a pulling device, and a cloth winding device. The tensioning device includes a tensioning roller group and a driving component. The tensioning roller group includes two relatively arranged support plates and tensioning roller I and tensioning roller II rotatably connected between the two support plates. One end of tensioning roller I and tensioning roller II on the same side passes through the support plate and gears meshing with each other are arranged at the ends. The driving component includes a driving sprocket, a driven sprocket, and a driving chain. The driven sprocket is fixed on tensioning roller I, and it also includes a driver for driving the driving sprocket to rotate; it has the function of independently winding the two pairs of fabrics knitted by the double needle bed warp knitting machine respectively.

[0004] In the actual application process, the following deficiencies still exist: In the production process of some existing warp knitting machines, due to the large width and long length of the fabric, in order to meet different production requirements, the warp knitting machine usually outputs the knitted fabric into multiple wide-width fabrics. In order to avoid wrinkles in the output and winding process of the fabric, a deviation prevention roller is usually installed at the front end of the warp knitting machine. The surface of the deviation prevention roller is usually designed with two convex reverse spirals extending from the middle to both ends. Since the spiral structure of the deviation prevention roller is fixed and unchanged, with the change of the processing requirements of different wide-width fabrics during the production process, it is necessary to re-customize the deviation prevention roller according to different fabric specifications, resulting in increased production costs; in addition, when the existing winding roller winds different wide-width fabrics, it cannot effectively limit each roll of fabric, resulting in the edges of the fabric not being able to be kept neat during the winding process, which not only affects the appearance quality of the fabric, but also increases the difficulty of subsequent finishing and processing, and reduces the production efficiency. Summary of the Invention

The cloth guiding device includes a cloth guiding roller arranged at the front end of the loop forming mechanism of the frame. Both ends of the cloth guiding roller are installed on both sides of the frame through bearing seats and are arranged parallel to the loop forming mechanism. A number of rotation mounting holes are equidistantly and uniformly distributed on the cloth guiding roller. A rotating shaft is penetrated and connected through the rotation mounting holes. A number of adjusting rings corresponding to the rotation mounting holes are arranged on the outer side of the cloth guiding roller. The inner diameter of the adjusting ring is 1.3 - 1.5 times the diameter of the cloth guiding roller. Both ends of the rotating shaft are fixedly connected to the inner side of the adjusting ring. A hollow mounting groove is arranged on the inner side of the cloth guiding roller. An inclination adjuster for separately driving the corresponding rotating shaft to rotate is arranged in the mounting groove. One end of the cloth guiding roller is connected with a driving motor.

[0008] As a further improvement, the inclination adjuster includes a sector gear piece coaxially connected to the middle of the rotating shaft, and a U-shaped fixing frame fixed in the mounting groove. A transmission lead screw is rotatably connected to the U-shaped fixing frame. The thread on the transmission lead screw meshes with the teeth of the sector gear piece. A driving motor is fixed at one end of the U-shaped fixing frame. Power supply devices and controllers for electrically connecting with the driving motor are also provided at both ends of the cloth guiding roller.

[0009] As a further improvement, the power supply device includes a number of first conductive rings evenly sleeved on the outer walls at both ends of the cloth guiding roller. The first conductive ring is provided with a connection terminal penetrating from the outer side of the cloth guiding roller to the mounting groove. The connection terminal is electrically connected to each driving motor. It also includes fixing seats sleeved on the outer sides at both ends of the cloth guiding roller. An extension plate is provided at one end of the fixing seat close to the side plate of the frame. The extension plate is fixedly connected to the side plate of the frame. A number of conductive grooves corresponding to the first conductive rings are formed inside the fixing seat. A number of power connection seats are arranged on the outer side of the fixing seat. Conductive connecting pieces for docking the first conductive ring with the power connection seats are arranged in the conductive grooves.

[0010] As a further improvement, the conductive connecting piece includes a second conductive ring sleeved on the inner side of the conductive groove. A number of contact pieces extending towards the first conductive ring and lapping with the first conductive ring are annularly distributed on the inner side of the second conductive ring.

[0011] As a further improvement, limit rings are arranged at both ends of the rotating shaft. A clamping step for cooperating with the limit ring is arranged outside the rotation mounting hole.

[0012] As a further improvement, the inclination adjusters are alternately distributed at the front and rear ends of the cloth guiding roller.

[0013] As a further improvement, the outer ring edge of the adjusting ring is provided with a fillet.

[0014] As a further improvement, the cloth winding mechanism includes support frames fixed to both sides of the front end of the machine frame, a winding roller rotatably installed in the middle of the support frames, a transmission motor provided on one side of the support frames for driving the winding roller to wind the cloth, and a plurality of limiting discs slidably connected to the winding roller for limiting the cloth.

Detailed Embodiments

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined. To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of the present invention.

[0034] During the production process of some existing warp knitting machines, due to the large width and long length of the fabric, in order to meet different production requirements, the warp knitting machine usually outputs the woven fabric into multiple wide-width fabrics. To avoid wrinkling of the fabric during output and winding, a deviation-preventing roller is usually installed at the front end of the warp knitting machine. The surface of the deviation-preventing roller is usually designed with two convex reverse spirals extending from the middle to both ends. Since the spiral structure of the deviation-preventing roller is fixed, with the change of processing requirements for different wide-width fabrics during the production process, it is necessary to re-customize the deviation-preventing roller according to different fabric specifications, resulting in increased production costs. In addition, when the existing winding roller winds different wide-width fabrics, it cannot effectively limit each roll of fabric, resulting in the edges of the fabric not being able to be kept neat during the winding process, which not only affects the appearance quality of the fabric but also increases the difficulty of subsequent finishing and processing and reduces the production efficiency. To solve the above technical problems, the following technical solutions are proposed in this case:

[0035] Refer to Figures 1 to 10 As shown in the figure, a double-needle bed warp knitting machine includes: a frame 1, a loop-forming mechanism 2 and a transmission mechanism 3 provided on the frame 1. A fabric guiding device 4 and a fabric winding mechanism 5 are further provided at the front end of the frame 1. The fabric guiding device 4 includes a fabric guiding roller 41 provided at the front end of the loop-forming mechanism 2 of the frame 1. Both ends of the fabric guiding roller 41 are installed on both sides of the frame 1 through bearing seats 42 and are arranged parallel to the loop-forming mechanism 2. A number of rotation mounting holes 43 are equidistantly and uniformly distributed on the fabric guiding roller 41. A rotating shaft 44 is connected through the rotation mounting holes 43. A number of adjusting rings 45 corresponding to the rotation mounting holes 43 are provided on the outer side of the fabric guiding roller 41. The inner diameter of the adjusting ring 45 is 1.3 - 1.5 times the diameter of the fabric guiding roller 41. Both ends of the rotating shaft 44 are fixedly connected to the inner side of the adjusting ring 45. A hollow mounting groove 46 is provided inside the fabric guiding roller 41. An inclination adjuster 6 that individually drives the corresponding rotating shaft 44 to rotate is provided in the mounting groove 46. One end of the fabric guiding roller 41 is connected to a driving motor 7;

[0036] Therefore, the fabric is woven by the looping mechanism 2, and then conveyed to the fabric winding mechanism 5 through the fabric guiding device 4. The fabric is wound by the fabric winding mechanism 5. When the fabric guiding device 4 is in use, the driving motor 7 drives the fabric guiding roller 41 to rotate in the bearing block 42. When conveying fabrics with multiple different widths, by adjusting the angle of each adjusting ring 45 on the fabric guiding roller 41, the adjusting rings 45 on the fabric guiding roller 41 are arranged to be inclined outward from the middle to both ends of each fabric with different widths. During the conveying process, the fabric contacts the surface of the adjusting ring 45. Then, as the fabric guiding roller 41 rotates, the fabric receives opposite acting forces towards both ends, ensuring that the fabric does not converge towards the middle, thus avoiding the wrinkling phenomenon of the fabric. Therefore, even when replacing fabrics with different widths for processing, by adjusting the inclination angle and orientation of each adjusting ring 45, making the adjusting ring 45 inclined outward from the middle to both ends of each fabric, the anti-deviation and anti-wrinkle effects during the fabric conveying process can be achieved;

[0037] Specifically, the inclination angle adjuster 6 controls each rotating shaft 44 on the fabric guiding roller 41 to rotate around the rotating mounting hole 43 respectively, prompting the adjusting ring 45 to rotate synchronously, thereby realizing the adjustment of the angle and orientation of the adjusting ring 45.

[0038] Among them, the inclination angle adjuster 6 includes a sector gear piece 61 coaxially connected to the middle of the rotating shaft 44, and a U-shaped fixing frame 62 fixed in the mounting groove 46. A transmission lead screw 63 is rotatably connected to the U-shaped fixing frame 62. The thread on the transmission lead screw 63 meshes with the teeth of the sector gear piece 61. One end of the U-shaped fixing frame 62 is fixed with a driving motor 64. Power supply devices 8 and controllers electrically connected to the driving motor 64 are also provided at both ends of the fabric guiding roller 41. When in use, an electrical signal is input through the controller, and the power supply device 8 is electrically connected to the driving motor 64, thereby driving the driving motor 64 to rotate in the positive direction. Then, the driving motor 64 drives the transmission lead screw 63 to rotate in the U-shaped fixing frame 62. Since the thread of the transmission lead screw 63 meshes with the teeth of the sector gear piece 61, and the sector gear piece 61 is fixedly connected to the rotating shaft 44, the sector gear piece 61 and the rotating shaft 44 are driven to rotate, and the adjusting ring 45 rotates synchronously with the rotating shaft 44, thereby realizing the adjustment of the angle and orientation of the adjusting ring 45, ensuring that the anti-deviation and anti-wrinkle effects can be achieved when conveying multiple sections of fabrics with different widths.

[0039] Further, the power supply device 8 includes a plurality of first conductive rings 81 evenly sleeved on the outer walls of both ends of the fabric guiding roller 41 at equal intervals. The first conductive ring 81 is provided with connection terminals 82 penetrating from the outside of the fabric guiding roller 41 to the installation groove 46. The connection terminals 82 are electrically connected to each driving motor 64. It further includes fixing seats 83 sleeved on the outer sides of both ends of the fabric guiding roller 41. One end of the fixing seat 83 close to the side plate of the frame 1 is provided with an extension plate 831, and the extension plate 831 is fixedly connected to the side plate of the frame 1. A plurality of conductive grooves corresponding to the first conductive rings 81 are formed inside the fixing seat 83. A plurality of power connection seats 84 are provided on the outside of the fixing seat 83. Conductive connectors 85 for docking the first conductive rings 81 and the power connection seats 84 are arranged in the conductive grooves. During use, the power connection seats 84 are connected to the controller through cables. The controller is mainly responsible for controlling the driving motors 64 to rotate forward and backward according to predetermined requirements. The connection terminals 82 are electrically connected to the driving motors 64. At the same time, the fixing seat 83 is coaxially connected to the fabric guiding roller 41. The fixing seat 83 is installed and fixed on both sides of the frame 1. The power connection seats 84 are electrically connected through the conductive connectors 85 and the first conductive rings 81. The first conductive rings 81 are electrically connected to the connection terminals 82. During the rotation of the fabric guiding roller 41, the fixing seat 83 remains stationary, and at the same time, the conductive connectors 85 and the first conductive rings 81 remain in an electrically connected state. Therefore, even when the fabric guiding roller 41 is in a rotating state, the inclination adjuster 6 can be controlled in real time to adjust the inclination and orientation of each adjusting ring 45, effectively avoiding problems such as fabric deviation and wrinkles, and improving the precision and efficiency of the production line.

[0040] The conductive connector 85 includes a second conductive ring 851 sleeved inside the conductive groove. A plurality of contact pieces 852 extending towards the first conductive ring 81 and overlapping with the first conductive ring 81 are annularly distributed inside the second conductive ring 851. The contact pieces 852 are copper spring pieces. Furthermore, the elastic characteristics of the spring pieces ensure the continuity and stability of the electrical connection, ensuring that the first conductive ring 81 and the second conductive ring 851 always maintain an electrical connection during the rotation of the fabric guiding roller 41.

[0041] Moreover, the first conductive ring 81, the connection terminals 82, the power connection seats 84, the conductive connectors 85, the second conductive ring 851, and the contact pieces 852 are all made of copper, ensuring conductive stability and also reducing energy loss during power transmission.

[0042] To ensure that the center of each adjusting ring 45 coincides with the rotation axis of the fabric guiding roller 41 and prevent the front and rear misalignment of two adjacent adjusting rings 45, limiting rings 441 are provided at both ends of the rotation axis 44, and a locking step 431 that cooperates with the limiting ring 441 is provided outside the rotation mounting hole 43. Then, the two limiting rings 441 are respectively buckled with the front and rear locking steps 431 of the rotation mounting hole 43, so as to ensure that during the rotation of the fabric guiding roller 41, the tops of the adjusting rings 45 always remain on the same horizontal plane, avoiding stretching deformation of the fabric caused by the offset and protrusion of the adjusting rings 45. When the fabric passes through the adjusting rings 45, it can maintain uniform tension and stable flow, ensuring the quality and processing accuracy of the fabric.

[0043] Meanwhile, the inclination adjusters 6 are alternately distributed at the front and rear ends of the fabric guiding roller 41, making the fabric guiding roller 41 more evenly stressed during rotation, preventing the fabric guiding roller 41 from deflecting, ensuring that the fabric maintains uniform tension and stable flow, and ensuring the quality and processing accuracy of the fabric.

[0044] The outer ring edge of the adjusting ring 45 is provided with a rounded corner to avoid scratching the fabric by the adjusting ring 45 during the fabric guiding process, resulting in damage or defects to the fabric, reducing the friction between the fabric surface and the adjusting ring, and keeping the fabric stable during transmission.

[0045] Specifically, the fabric winding mechanism 5 includes support frames 51 fixed to both sides of the front end of the frame 1, a winding roller 52 rotatably mounted in the middle of the support frames 51, a transmission motor 53 provided on one side of the support frame 51 to drive the winding roller 52 to wind the fabric, and a plurality of limiting disks 54 slidably connected to the winding roller 52 for limiting the fabric. Therefore, during use, the fabric winding cylinder is placed into the winding roller 52, and the transmission motor 53 drives the winding roller 52 to rotate in the support frames 51, thereby realizing the fabric winding work; when winding fabrics of multiple different widths, by horizontally moving the limiting disks 54, the limiting disks 54 are just aligned with both ends of the fabric winding cylinder, so as to realize the limitation of the winding of fabrics of different widths, ensure that the edges of the fabric are aligned during winding, reduce the subsequent finishing and processing difficulties, and improve the production efficiency.

[0046] Among them, a plurality of chutes 521 extending along the axial direction thereof are provided on the surface of the winding roller 52, a convex tooth 541 matching with the chute 521 is arranged inside the limiting disc 54, a locking piece 542 protruding outwards is arranged on one side of the limiting disc 54, and a plurality of bolt holes 522 for fixing the locking piece 542 are arranged on the winding roller 52. Therefore, during use, the limiting disc 54 is driven to slide on the winding roller 52, so that the convex tooth 541 of the limiting disc 54 slides along the chute 521. After the limiting disc 54 is adjusted to a proper position, the locking piece 542 and the bolt hole 522 are tightly connected by bolts, so as to ensure that the limiting disc 54 remains fixed during the winding process and prevent relative rotation between the limiting disc 54 and the winding roller 52, thus ensuring the winding precision and the neatness of the fabric.

[0047] Scales are provided on the surface of the winding roller 52, which is beneficial to quickly positioning the installation position of the limiting disc 54, thereby ensuring the high efficiency and precision during the winding process.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
