Description

Technical Field

[0001] This application relates to the technical field of warp knitting machines, and in particular to an extension bracket for a warp knitting machine. Background Technology

[0002] Warp knitting machines play a vital role in the textile industry. They form fabrics by simultaneously weaving one or more sets of parallel yarns (warp yarns) longitudinally into loops that interlock. Warp knitting production is characterized by high efficiency, a wide variety of fabrics, and broad applications, with its products widely used in clothing, home textiles, industrial textiles, and many other fields. With continuous technological advancements, modern warp knitting machines are evolving towards higher speeds, wider widths, and greater intelligence. This has further solidified their importance in the textile industry, significantly driving its development and meeting market demands for various high-quality warp-knitted fabrics.

[0003] In traditional warp knitting technology, to achieve fabric output and take-up, the output and take-up devices were typically positioned close to or in front of the knitting area. After the fabric was drawn from the knitting area, it would quickly descend and be wound onto the take-up roller located below and in front of the machine. This layout was the standard method for solving the fabric take-up problem at the time. During daily operation of the warp knitting machine, this layout was also generally followed when encountering unexpected situations such as cleaning the loop-forming mechanism (e.g., guide bars, needle bed, sinkers), replacing worn parts, adjusting yarn tension, or dealing with yarn breaks or fabric defects.

[0004] However, the existing arrangement of the fabric output and take-up devices on warp knitting machines has significant drawbacks. When it is necessary to inspect the lower front components of the machine or to closely observe and process the weaving condition of the fabric's front side (process side), the retracted fabric roll and its supporting structure severely obstruct the operator's view and operating space. Operators are forced to adopt inconvenient postures such as bending over, squatting, or even crouching, or to frequently start and stop the equipment and remove the fabric roll to continue working. This not only leads to low efficiency in maintenance and debugging operations but also increases the labor intensity of operators and poses certain safety hazards. Summary of the Invention

[0025] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0026] This application discloses an extension bracket for a warp knitting machine.

[0027] This application mainly adopts the method of setting an extension bracket at the output port of the warp knitting machine to wind up the fabric, which achieves the effect of facilitating the maintenance and debugging of the warp knitting machine and improving the operating efficiency. The following is a further detailed description of this application. Example

[0028] See Figure 1 and Figure 2 This application provides an extension bracket for a warp knitting machine, comprising an extension frame 1, a support column 2, a passageway plate 3, a support frame 4, and a winding roller 5 (the winding roller 5 is in...). Figure 3 The machine comprises a winch, a rotating roller 6, and a power assembly 7. The extension frame 1 is fixedly connected to one side of the warp knitting machine's outlet. Support columns 2 are fixedly connected to the extension frame 1. There are two support columns 2, symmetrically arranged horizontally away from the warp knitting machine's outlet. A walkway plate 3 is mounted on the opposite support columns 2. A support frame 4 is mounted on the support columns 2 away from the warp knitting machine. The winding roller 5 is rotatably connected to the opposite bearing block 41 (the bearing block 41 is located on...). Figure 4 Between (the marked points). The rotating roller 6 is rotatably connected to the extension frame 1 and located below the winding roller 5. The power assembly 7 is set on the extension frame 1, thus forming an overall structure that facilitates the winding of the warp knitting machine fabric and does not hinder maintenance and debugging. By extending the fabric to the extension frame for winding, the winding fabric roll and its support structure avoid obstructing the maintenance of the lower front parts of the warp knitting machine and the observation and processing of the weaving status of the fabric face, thereby improving the efficiency of maintenance and debugging operations, reducing labor intensity, and reducing safety hazards.

[0029] Specifically, as the basic support structure of the entire extension frame, extension frame 1 needs to possess a certain level of strength and stability. The material of extension frame 1 can be high-strength steel, such as Q235 steel, which has good strength and toughness, meeting the load-bearing requirements of the extension frame. Extension frame 1 can be assembled using welding or bolt connections to ensure its structural stability. The shape of extension frame 1 can be designed according to the specific structure of the warp knitting machine and site requirements; a common design is a frame structure, which offers high space utilization and load-bearing capacity.

[0030] Support column 2 is horizontally and fixedly connected to extension frame 1, used to support walkway slab 3 and provide installation position for support frame 4. Support column 2 can be made of round or square steel pipe, with the wall thickness selected based on actual load-bearing requirements. Taking square steel pipe as an example, its cross-sectional dimensions can be adjusted according to the size of extension frame 1 and load-bearing requirements. The connection between support column 2 and extension frame 1 can be welding or bolting, ensuring a firm and reliable connection between them.

[0031] The passageway plate 3 is set on the opposite support column 2. The extension frame 1 is rotatably connected to the transmission roller 11. The transmission roller 11 is located below the passageway plate 3. The finished fabric output from the warp knitting machine outlet is transmitted through the transmission roller 11 and passes under the passageway plate 3, reducing the possibility of the fabric wrapping affecting the maintenance of the warp knitting machine.

[0032] See Figure 2 and Figure 4 The support frame 4 is detachably fixed to the support column 2 located away from the warp knitting machine. Support blocks 41 slide vertically and vertically on the support frame 4. The support frame 4 can be made of steel plate, providing high strength and stability. The sliding of the support blocks 41 can be achieved by providing vertically extending moving grooves on the support frame 4. In other embodiments, the sliding of the support blocks 41 can also be achieved by a guide rail, which can be a linear guide rail, offering high precision and smooth sliding. The support blocks 41 can be designed according to the weight and size of the winding roller 5 to ensure stable support of the winding roller 5.

[0033] The winding roller 5 is rotatably connected between opposing support blocks 41 and is used to wind the fabric woven by the warp knitting machine. The winding roller 5 can be a solid or hollow shaft, and the material can be aluminum alloy, which is lightweight and high-strength. The surface of the winding roller 5 can be polished to reduce wear on the fabric. The rotatable connection between the winding roller 5 and the support block 41 can be achieved through bearings, and deep groove ball bearings can be selected, which have high rotational accuracy and reliability.

[0034] The rotating roller 6 is rotatably connected to the extension frame 1 and located below the winding roller 5. The rotating rollers 6 are symmetrically arranged in the horizontal direction. In the initial state, the rotating rollers 6 are in contact with one of the other rotating rollers 6 by gravity. At this time, the two rotating rollers 6 rotate in opposite directions, conveying the fabric output from the warp knitting machine outlet and transported below the guide plate 3 to the winding roller 5. Then, the rotating roller 6 and the winding roller 5 can be driven by friction or a transmission belt to ensure that the rotating roller 6 can effectively drive the winding roller 5 to rotate, so that the winding roller 5 rotates to wind the fabric. As the number of layers of fabric increases, the winding roller 5 drives the support block 41 to move upward. The rotating roller 6 can also be made of aluminum alloy, and the diameter and length of the rotating roller 6 are designed according to actual needs. The rotatable connection between the rotating roller 6 and the extension frame 1 can also be achieved through bearings.

[0035] The power assembly 7 includes a power helical gear 71, a transmission helical gear 72, and a power motor 73. The transmission helical gear 72 is mounted on the roller shaft at one end of one of the rotating rollers 6. The power motor 73 is mounted and fixed on the extension frame 1. The power helical gear 71 is fixedly connected to the output shaft of the power motor 73, and the power helical gear 71 meshes with the transmission helical gear 72. The power motor 73 can be a three-phase asynchronous motor, characterized by high efficiency and high reliability. The power helical gear 71 and the transmission helical gear 72 can be made of alloy steel, which has high hardness and wear resistance. The module and number of teeth of the power helical gear and the transmission helical gear 72 are designed according to the requirements of the transmission ratio.

[0036] The combination logic of these components is as follows: the power motor 73 drives one of the rotating rollers 6 to rotate via the power helical gear 71 and the transmission helical gear 72, while the fabric passes between the two rotating rollers 6. At this time, the friction between the two rotating rollers 6 drives the fabric to be fed to the winding roller 5. Simultaneously, the rotation of the rotating roller 6 drives the winding roller 5 to rotate, thus achieving the winding of the fabric. The adjustable structure of the walkway plate 3 can be adjusted in height according to actual needs, making it convenient for workers to walk and operate on it. The design of the support frame 4 and the load-bearing block 41 ensures that the winding roller 5 works stably at different heights. This combination method enables the entire extension bracket to effectively complete the winding of the fabric, while avoiding the impact on the maintenance and debugging of the warp knitting machine.

[0037] The implementation principle of the warp knitting machine extension bracket in Embodiment 1 of this application is as follows: This warp knitting machine extension bracket moves the fabric winding position from below the front of the machine to the extension bracket, avoiding the obstruction of the wound fabric roll and its support structure to the machine's maintenance and debugging operations. The power unit 7 provides power, causing the rotating roller 6 to drive the winding roller 5, thus achieving fabric winding. The adjustable structure of the guide plate 3 facilitates operator operation and improves work efficiency. The design of the support frame 4 and the load-bearing block 41 ensures the stable operation of the winding roller 5. Compared to the traditional fabric output and winding devices of warp knitting machines, this extension bracket significantly improves the efficiency of warp knitting machine maintenance and debugging, reduces the labor intensity of operators, and minimizes safety hazards, representing an effective improvement over existing technology. Example

[0038] See Figure 5 and Figure 6The difference between Embodiment 2 and Embodiment 1 is that the passageway panel 3 includes a first panel 31 with a "U" shape and a second panel 32 with a "U" shape. The first panel 31 is fastened to the support column 2 and corresponds to it. Sliding grooves 311 are respectively opened on the opposite sides of the first panel 31. Sliding strips 321 are fixedly connected to both ends of the second panel 32. The sliding strips 321 are slidably connected to the sliding grooves 311, so that the two ends of the second panel 32 are respectively connected to the two opposite first panels 31. At this time, the first panel 31 provides support for the second panel 32.

[0039] See Figure 6 and Figure 7 When the slider 321 slides into the groove 311, the opening of the second plate 32 can be set upwards or downwards. When the opening of the second plate 32 is set upwards, the vertical height of the side plate used for standing during maintenance decreases; when the opening of the second plate 32 is set downwards, the vertical height of the side plate used for standing during maintenance increases. The first plate 31 can be made of metal sheet, such as stainless steel, which has the characteristics of corrosion resistance and high strength. The "U"-shaped structure of the first plate 31 can be made by bending process to ensure the integrity of the structure. The second plate 32 can also be made of metal sheet. The fit tolerance between the slider 321 and the groove 311 of the first plate 31 must be controlled within a reasonable range to ensure that the slider 321 can slide smoothly in the groove 311. The connection between the first plate 31 and the second plate 32 adopts a sliding fit, which facilitates the adjustment of the length of the passageway plate 3 according to actual needs and adapts to different working scenarios. To improve the connection stability between the first plate 31 and the second plate 32, the groove shape of the slide bar 321 and the groove 311 can be a "T" shape.

[0040] See Figure 8 and Figure 9Multiple insertion posts 312 slide vertically on the first plate 31, and insertion holes 322 are formed on the slide bar 321 for the insertion posts 312 to be inserted. The insertion posts 312 can be cylindrical, and the material of the insertion posts 312 can be carbon steel, which has high hardness and wear resistance. A linkage bar 313 is fixedly connected to the top of the insertion posts 312, which can connect multiple insertion posts 312 together for convenient simultaneous operation. A fixing bolt 314 is rotatably connected to the linkage bar 313, and the fixing bolt 314 is threaded to the first plate 31. By rotating the fixing bolt 314, the linkage bar 313 can drive the insertion posts 312 to move up and down, thereby realizing the insertion and removal of the insertion posts 312 from the insertion holes 322, which facilitates the fixation of the position of the second plate 32. The first plate 31 has a multi-segment structure. One end of the first plate 31 is fixedly connected to a locking block 315, and the other end of the first plate 31 has a locking groove 316, into which the locking block 315 is inserted. This multi-segment structure facilitates transportation and installation. Through the cooperation of the locking block 315 and the locking groove 316, the segments of the first plate 31 can be quickly connected together, ensuring the stability of the connection.

[0041] The implementation principle of the warp knitting machine extension bracket in Embodiment 2 of this application is as follows: By adjusting the connection method between the first plate 31 and the second plate 32, and by adjusting the orientation of the opening of the second plate 32, the vertical height of the side plate used for standing during maintenance is lowered when the opening is set upwards; and the vertical height of the side plate used for standing during maintenance is raised when the opening of the second plate 32 is set downwards.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
