Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a warp knitting machine yarn selection mechanism based on multiple pay-off roller switching. Background Technology

[0002] A warp knitting machine is a type of textile machinery. It is primarily used for weaving warp-knitted fabrics. Warp-knitted fabrics are made by interlocking one or more groups of parallel yarns (warp yarns) along the warp direction of the fabric. Under the action of loop-forming components such as hook needles or latch needles on the warp knitting machine, these yarns form loops, thus creating a fabric with a specific structure and pattern. For example, many lace fabrics and swimwear fabrics are woven using warp knitting machines.

[0003] In existing technology, when changing to different yarns, the disassembly and installation of the yarn rollers on a general warp knitting machine is quite cumbersome. Furthermore, the yarn bobbins need to be inserted one by one and positioned and fixed simultaneously during installation. This not only results in low work efficiency but also fails to guarantee the accuracy of the positioning and installation, which may affect the subsequent knitting quality. Utility Model Content

[0004] This utility model discloses a warp knitting machine yarn selection mechanism based on multiple yarn feeding roller switching, which aims to solve the technical problems of the cumbersome operation when changing different yarns in general warp knitting machines, and the need to insert and position the yarn bobbins one by one during installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A warp knitting machine yarn selection mechanism based on multiple pay-off roller switching includes a main frame. A single yarn guide roller is movably connected to the inner walls of opposite sides of the main frame. A quick-switching module is installed inside the main frame, comprising a rotating frame. A circular hole is provided on the main frame, and the rotating frame is movably connected within the circular hole. Multiple circumferentially equidistant mounting rods are fixedly connected to the inner walls of opposite sides of the rotating frame. A fixing kit is fixedly connected to one side of each mounting rod. A yarn cleaning module is installed on the rotating frame, comprising multiple circumferentially equidistant negative pressure chambers. Each negative pressure chamber has a dust suction port and is fixedly connected to the inner wall of the rotating frame. Movable rods are slidably connected to the inner walls of each fixing kit, and springs are fixedly connected to one side of each fixing kit. The ends of each springs away from the fixing kits are fixedly connected to... Each movable rod has multiple sliding parts fixedly connected at equal intervals to its outer surface. These sliding parts slide against the inner wall of their respective mounting rods. A fixing ring is fixedly connected to the outer wall of the movable rod at the end furthest from the fixing assembly. A push rod is fixedly connected to each fixing ring. Each mounting rod has a locking slot, and the push rod slides within the corresponding locking slot. Each sliding part has a mounting hole at the end furthest from the movable rod, and a fixing rod is fixedly connected within each mounting hole. Each fixing rod has an annular groove, and a locking movable part is movably connected within each annular groove. A yarn bobbin body is slidably connected to the outer surface of each locking movable part. A drive motor is fixedly connected to one side of the main frame, and a transmission wheel is fixedly connected to both the output end of the drive motor and the outer wall of the rotating frame. The two transmission wheels are slidably connected to the same transmission belt.

[0007] Equipped with a quick-switching module, when different yarns need to be changed, the drive motor rotates the rotating frame, bringing another mounting rod containing different yarns closer to the guide roller, thus completing the quick switch. When replacing the yarn bobbin body, the push rod is pushed to slide into the locking slot, which in turn pushes the movable rod to move multiple sliding parts and the fixed rod synchronously, causing multiple locking movable parts to move to one side with the yarn bobbin body. Then, the push rod is rotated to lock into the locking slot for limiting. After the replacement is completed, the push rod is released from the locking slot, and the spring elastically returns to its original position, pushing the movable rod back to reset, thus completing the positioning and installation of the yarn bobbin body, improving work efficiency and accuracy.

[0008] In a preferred embodiment, cleaning kits are fixedly connected to the exterior of multiple negative pressure chambers, and multiple circumferentially equidistant movable rollers are movably connected to the inner walls of opposite sides of the rotating frame. Multiple circumferentially equidistant negative pressure pumps are fixedly connected to the rotating frame, and connecting pipes are fixedly connected to the output ends of the multiple negative pressure pumps. The ends of the multiple connecting pipes away from the negative pressure pumps pass through the cleaning kits and are fixedly connected to the corresponding negative pressure chambers. Multiple circumferentially equidistant sliding grooves are opened on the inner walls of opposite sides of the rotating frame. Limiting rods are fixedly connected to the sliding grooves, and sliding blocks are slidably connected to the outer walls of the multiple limiting rods. The same tension roller is movably connected to one side of the sliding blocks on opposite sides, and springs are wrapped around the outside of the multiple limiting rods. One end of the multiple springs is fixedly connected to the rotating frame, and the other end is fixedly connected to the corresponding sliding block.

[0009] By incorporating a yarn cleaning module, dust, fly ash, and other impurities on the yarn surface are brushed off by the cleaning kit as the yarn passes through the module. Simultaneously, a negative pressure pump is activated to maintain a negative pressure state within the negative pressure chamber, sucking up the impurities and preventing them from entering the weaving area and affecting fabric quality, thus improving the device's practicality. Furthermore, by incorporating a second spring, the elasticity of the second spring allows for a certain degree of tension adjustment of the yarn sliding outside the tension roller.

[0010] As can be seen from the above, the warp knitting machine yarn selection mechanism based on multi-roller switching provided by this utility model can quickly switch between different yarns without disassembling and reinstalling the yarn rollers when different yarns need to be changed. By rotating the rotating frame, the mounting rods with different yarns are brought close to the guide rollers. At the same time, when installing the yarn bobbins, there is no need to insert and position them one by one. The yarn bobbins are snapped onto the outside of the snap-fit ​​movable parts, and the quick switching module can be used for convenient positioning and installation, improving work efficiency and accuracy. Furthermore, the yarn cleaning module can brush away dust, fly hair and other impurities on the surface of the yarn as it passes through, and the negative pressure chamber sucks them up to prevent impurities from entering the knitting area, thus improving the quality of the fabric.

[0019] Reference Figure 1 , Figure 2 and Figure 4In a preferred embodiment, cleaning kits 303 are fixedly connected to the exterior of multiple negative pressure chambers 302, and multiple circumferentially equidistant movable rollers 301 are movably connected to the inner walls of opposite sides of the rotating frame 204. Multiple circumferentially equidistant negative pressure pumps 304 are fixedly connected to the rotating frame 204, and connecting pipes 305 are fixedly connected to the output ends of the multiple negative pressure pumps 304.

[0020] Working principle: When it is necessary to change to a different yarn, start the drive motor 201, which drives the rotating frame 204 to rotate through the transmission wheel 203 and the transmission belt 202, so that another mounting rod 205 with different yarns is brought close to the guide roller 4, thus completing the quick switch; when it is necessary to replace the yarn bobbin body 9 on the mounting rod 205, push the push rod 214 to slide it into the locking slot 212, and push the movable rod 208 through the fixing ring 213, which drives multiple sliding parts 209 to move synchronously with the fixing rod 210, so that multiple locking movable parts 211 and the yarn bobbin body 9 move to one side, and then rotate the push rod 214 to make it move to the other side. After the yarn bobbin body 9 is replaced, the push rod 214 is rotated again to disengage it from the slot 212. The spring 207 returns to its elastic state and pushes the movable rod 208 to reset, thus completing the positioning and installation of the yarn bobbin body 9. The tension of the yarn sliding outside the tension roller 8 is adjusted by the elastic action of the spring 6. When the yarn passes through the yarn cleaning module 3, the cleaning kit 303 brushes off the dust, fly hair and other impurities on the surface of the yarn. At the same time, the negative pressure pump 304 is started to maintain a negative pressure state in the negative pressure chamber 302 to suck up the impurities and prevent them from entering the weaving area and affecting the fabric quality.
