Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to a novel high-speed single-sided warp knitting machine. Background Art

[0002] The warp knitting machine uses one or several groups of parallel yarns to form loops on all the working needles of the machine fed in the warp direction at the same time to form a knitted fabric. This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The main loop forming parts of the warp knitting machine are knitting needles, yarn guide needles, sinkers and pressing plates (for crochet machines). The knitting needles are installed on the needle bed in a row and move with the needle bed. The yarn guide needles are installed on the strips to form a comb. The warp yarn passes through the eye of the yarn guide needle, moves with the comb bar and wraps around the needle. The fabric is woven through the mutual cooperation of the knitting needles, sinkers and other loop forming parts. In the warp knitting machine, the comb bar is an important part of the warp knitting machine weaving loop. On the warp knitting machine with a smaller width, the comb bar transmission can ensure the needle position through spring recovery.

[0003] The existing warp knitting machines have the following problems: With the advancement of science and technology and the improvement of people's living standards, the demand is also constantly changing.

[0019] Furthermore, the inner cavity of the connecting rod frame 10 is rotatably connected to a crankshaft 11 , and the outer surface of the crankshaft 11 is rotatably connected to a groove needle transmission rod assembly 7 , a needle core transmission rod assembly 8 , and a sedimentation transmission rod assembly 12 .

[0020] Furthermore, one end of the comb bar driving rod assembly 1 away from the crankshaft 11 is rotatably connected to the comb bar swing arm 2. The comb bar swing arm 2 is installed on the front end surface of the middle wall plate 6, and the rear end surface of the middle wall plate 6 is fixedly connected to the oil tank 9.

[0021] Furthermore, the oil tank 9 is fixedly connected to the oil cylinder assembly 14 , and the right end surface of the crankshaft 11 is fixedly connected to the output end of the servo motor 13 .

[0022] Furthermore, one end of the groove needle transmission rod assembly 7 away from the crankshaft 11 is rotatably connected to the groove needle four-bar linkage 5, the upper end surface of the groove needle four-bar linkage 5 is fixedly connected to the needle core four-bar linkage 4, and one side of the upper end surface of the needle core four-bar linkage 4 is fixedly connected to the sinking four-bar linkage 3.

[0024] Working principle: When weaving, start the variable frequency motor to make the output end of the variable frequency motor rotate, so the crankshaft rotates, so that the crankshaft rotates one circle clockwise. When the crankshaft rotates to 0°~135°, the slot needle rises to the first high point. At this time, the comb drive the yarn needle block to rotate around the fulcrum to the rear of the machine. When the crankshaft rotates to 135°~180°, the slot needle slowly descends to make way for the comb yarn needle block, and the comb yarn needle block rotates to the rear of the machine, and the preparation for the yarn introduction into the slot needle is completed; when the crankshaft rotates to 1 When the angle is 80°~225°, the groove needle rises to the second highest point, and at the same time, the comb yarn needle block rotates around the fulcrum to the front of the machine, successfully guiding the thread to the groove needle. When the crankshaft rotates to 225°~340°, the groove needle drops, and at the same time, the needle core rises when it opens, blocking the groove needle mouth, so that the yarn does not run out of the groove needle. At this time, it sinks and retreats, allowing the groove needle to smoothly drop and weave the thread. When the crankshaft rotates to 340°~360°, the groove needle drops to the initial point, and at the same time sinks forward, allowing the groove needle to smoothly unloop to the initial point. When the braiding structure needs to be moved horizontally, the servo motor directly drives the lead screw in the oil cylinder, and the guide bar moves left and right through the sliding of the lead screw; the number of needles for horizontal movement can be set arbitrarily through PLC electronic control. Core technology: Direct drive by servo motor, precise positioning, high efficiency, more accurate than stepper motor, low energy consumption, simpler and more direct structure, small error, high precision.
